Description

Transversal support provision for railroad passing device

The present invention relates to a transverse support arrangement for a passage device railway

From document DE 196 23 135 A1, knows a railroad crossing device, in which between the two rails of a railway installation and respectively in the outside of the rails there are groups of pass plates railway Each of these groups comprises a plurality of sequential plates in a longitudinal direction of the device of railway passage. These individual plates or groups of plates they are grouped in an interconnection by tie rods that they extend through these plates or on their underside in the longitudinal direction of the railroad passing device and also they are retained with reference to the bottom in the longitudinal direction of the railroad passing device. Step plates Individuals of these groups are structured from rubber or a material that contains rubber. Particularly, in this case, it uses rubber waste granules, by way of example, obtained from from reprocessing vehicle wheels. The grains individual granules are fixedly joined together by a binder. These plates manufactured from a material of rubber or rubber waste granules settle on the sides top of the sleepers of the railway installation, in which the railroad passage device is available or has to be arranged. In the area of the individual rail fixing points, they provide in the areas adjacent to the recess lanes in these plates. The length of the plates must be adjusted from comparatively accurate way to the division of sleepers or the separation between sleepers, since, in this way, the plates individual are supported in their adjacent area by the sleepers and comparatively strong efforts as they occur, by way of example, during the crossing with vehicles, they cannot lead to local movements too strong downward deflection of individual plates

From the document US-A-4,266,718 a known railway passage device in which between the rails of a railway installation are immobilized by thread molded elements on wooden sleepers. The surface of these elements molded is coated for the formation of a flat finish by cover plates that must also be retained by Thread on the wooden sleepers.

From EP 0 145 609 A it is known a railroad crossing device, in which they are arranged adjustable devices for observing separation between rails and internal step plates.

It is the objective of the present invention provide a transversal support provision with which they can support the step plates of a step device railway between a rail and a lateral delimitation of the passage with compensation of variations in separation.

In accordance with the invention, this is resolved objective for a transversal support provision for the support of a step plate in a lateral delimitation of the passage, essentially transverse to a longitudinal direction of a railroad passage device according to claim 1. It includes a first support area in the delimitation side of the passage and a second support area on a step plate, where the first support zone and the second support zone concur as a wedge in a height direction for the formation of a intermediate space that decreases in height direction, which it also includes a support element that is supported by the first support zone and the second support zone and that is coupled or can be coupled with a support zone of the first zone support and the second support zone in different positions of height and so that it cannot move in the direction of height.

With a transversal support provision of this type becomes possible regardless of the type in which they are configured the step plates or if they are superimposed Several layers of these step plates compensate for variations in the separation between a railway installation, particularly between the lanes of the same, and a lateral delimitation of the He passed. This is particularly important also when reformed railway facilities with gravel after a prolonged duration of operation and are no longer placed exactly in the lateral situation with reference to the delimitation lateral step, as previously was the case.

To ensure the possibility of adjusting the location of the support element in the height direction, without However, ensuring a stable coupling with a support zone, it also proposes that the support element present a first toothed formation and that a support area has a second toothed formation that is situated in or can lead to a coupling gear with the first toothed formation.

The support area can be, by way of example, The second support zone.

The invention further relates to a device of railway passage with a transverse support arrangement of this type, which comprises at least a first group of pass plates with sequential bearing structure in a longitudinal direction of the railroad crossing device, as well as a second group of sequential cover step plates in the direction longitudinal of the rail passage device that are held on the step plates with bearing structure and presenting a usable top side, particularly, on which you can drive and / or ride

Therefore, the railroad passing device It comprises two groups of step plates that act together functionally The first group, that is, the step plates with bearing structure, forms the substructure and makes available the bearing structure for the second group, that is, the plates of cover step. These deck step plates, therefore, already do not lean on the sleepers or any other fund, but, they they place on the step plates of the first group. Therefore, the deck pass plates of the second group are independent of the situation and the mutual separation of the sleepers of a railway installation with respect to its size and placement. This is advantageously perceived particularly also in a curve zone, where the mutual separation between sleepers is greater in the outer zone of the curve than in the inner zone of the curve. The structured cover step plates with a uniform size will they can place independently of deviations of this type in the separation between sleepers and, in fact, directly adjacent. Variations in the separation between sleepers can be compensated in the area of the first group pass plates. However, the deck step plates do not have to be configured in such a way that also absorb and support all the load that is exerted from above. In this case, this is the first function of the step plates with bearing structure, which can be optimized with Regarding this load support function.

The cover step plates may be essentially placed loosely on these carrier plates  passing with bearing structure. That is, it does not have to be created no fixed interconnection between these two groups of plates, by way of for example, by adhesion, rivet or thread.

However, alternatively it also can provide that the second group of deck passage plates is anchored with reference to this first plate bearing group passing with bearing structure. In this way, a interconnection between the two groups of plates that ensures that, particularly during an oblique crossing with heavy vehicles, it can avoid as far as possible a relative displacement of Two groups with reference to each other.

However, to ensure that, also in the case of the railway crossing device according to the invention, the crossing with trains with a comparatively speed high can not lead to unwanted takeoff of step plates individual, it is also proposed that the cover step plates are held together in an interconnection by a provision of tension elements extending in the longitudinal direction of the railroad passing device. In this case, preferably, it is also expected that the interconnection is anchored in at least one area longitudinal terminal of the second group with reference to a background.

In order to easily provide the interconnection between the two groups mentioned previously, it is proposed that the provision of elements of voltage is anchored at least with reference to a step plate with bearing structure

Pass plates with bearing structure they can be configured in a first terminal zone for the support in a lane and, in that place, they can carry, to put provision a certain elasticity or flexibility during placement, an elastic seat for support with reference to rail.

Particularly, when the step plates with bearing structure of the first group are structured in a metal material, by way of example, an aluminum material or steel, it is advantageous or necessary that the step plates with bearing structure are electrically insulated in their first zone terminal with reference to the rail and / or a fixing device lanes This can be provided in a configuration that is you can perform very easily because the elastic seat makes electrical insulation available.

In a second terminal zone the step plates with bearing structure can be configured for support with reference to a lateral delimitation of the passage. A delimitation side of the passage of this type may be formed, by way of example, for roadway delimitation blocks made of a concrete material, with which then limits the roadway that leads to the railroad passing device.

In order to make available a greater flexibility during placement of the passage device railway according to the invention also in a manner transversal to its longitudinal direction, it is proposed in addition to at least one, preferably all step plates with supporting structure are supported in its second terminal area essentially transverse to the longitudinal direction of the railway passage device through an adjustable arrangement of transversal support. For the possibility of adjusting the Transversal support provision ensures that neither light separation variations between the rails, on the one hand, and a lateral delimitation of the passage, on the other hand, can lead to deformations or, also, excessive movement slack.

To be able to make available, also with the structure according to the invention with two groups of plates step that are superimposed, a very constructive type low, which lines up flush with both the surfaces of the rails, that is, the rolling surfaces of the rails, as with the adjacent roadway, it is proposed that at least one, preferably all step plates with bearing structure present between your first terminal zone and your second terminal zone a cutout for sleeper sleepers. Therefore, they have a elementary importance particularly the areas of the plates of step with bearing structure that mesh between two sleepers, is that is, in so-called crossbeam boxes, for setting up high resistance arrangement.

         \ newpage
      

A constructive type that is constructed in a way very low, although, however, stable in the area of the plates step with bearing structure, you can expect the step plates with supporting structure make available in its second zone terminal a seating surface for the passage plates of cover, which is essentially flush with a seating surface that is made available in a central area of the step plates with supporting structure.

According to an additional aspect particularly advantageous of the rail passage device of according to the invention it is proposed that at least one, preferably all step plates with bearing structure present in the longitudinal direction of the passage device railway an extension that is less than the average separation between sleepers of a railway installation in which you have We provide the railroad crossing device. This has the consequence of at least in different areas between the plates step with directly adjacent individual bearing structure intermediate spaces are formed. These intermediate spaces can be larger where the plates with bearing structure are placed in an external zone of the curve and may be smaller where step plates with bearing structure are located in an area internal curve. However, the existence of spaces Intermediates of this type is not problematic, since they are covered by deck step plates. However, due to the fact that these intermediate spaces are comparatively small and can be place in the range of a few centimeters, there is no danger of covering deck passage plates being diverted down during an effort.

At least one of the cover step plates, preferably all cover step plates, may be structured with the use of rubber granulate, preferably, rubber waste granulate.

The or at least one of the step plates with bearing structure may be structured with a material of hollow profile, that is, by way of example, of profile supports aluminum hollow Alternatively, of course, it is also possible to manufacture the at least one of the step plates with bearing structure with a casting material such as a concrete material, fiber composite materials, wood, etc.

You can avoid unwanted take-off of cover step plates of the structure step plates bearing, particularly during the crossing with faster trains, why the cover step plates present in an area terminal, which has to be located near the lanes, or / and in a terminal area, which has to be located far from the rails, a gear formation with drag for a gear with drag in the direction of height with a rail or a lateral delimitation of the passage.

In the figures it is generally indicated with 10 a railway passage device according to the invention. This railway passage device 10 is shown together with a railway installation 12 comprising in a constructive type conventional a plurality of sleepers 14 arranged so sequential in a longitudinal direction L of the installation rail 12 and the rail crossing device 10. In these sleepers 14 are supported with a lateral separation the rails 16, 18, where lanes 16, 18 are immobilized in the crossings 14 respectively by so-called support points individual 20. Rails 14 may be incorporated in a gravel bed, however, by way of example, in the case of a railway installation 12 of the constructive type of firm roadway, they can also be included by casting in a stratum of concrete, from which they can stand out with their upper zone.

It is provided laterally to the installation railway 12 a lateral delimitation of step 22, in the area in the one that the railroad passage device has to provide 10 and, therefore, a roadway, a sidewalk or similar through the railway installation 12. This includes generally a plurality of boundary blocks 24 arranged sequentially in the longitudinal direction L, whose contour will be discussed still below and that generally They are made from a concrete material. With these roadway delimitation blocks 24 then limits, by way of example, a paved road.

The rail passage device 10 produces, in the example represented in Figures 1 and 2, a passage zone between the roadway, that is, the lateral delimitation of step 22, and lane 18. It is assumed that also on the other side of the railway installation 12, that is, between lane 16 and the adjacent roadway at that location, a corresponding arrangement, as well as between rails 16 and 18.

The rail passage device 10 comprises Two groups of step plates. A first group 26 makes available step plates with bearing structure 28. A plurality of these step plates with bearing structure 18 are arranged sequential in the longitudinal direction L, so that extend between lane 18 and the lateral delimitation of step 22, that is, blocks 24. Each of these step plates with bearing structure 28 sits in a first terminal zone 30 on lane 18, in fact, the foot of lane 32 thereof and, of In fact, as Figure 5 can expressly recognize, on an elastic seat element 34. This is held in a support element 36 configured as a hollow profile piece, by adhesion, by introduction in corresponding recesses profile or similar and, therefore, is immobilized. The outline of support element 36 in the area adjacent to lane 18 or foot of lane 32 thereof is adapted to the conformation of the lane 18 in this area.

In a second terminal zone 40 is provided an additional support element 38 configured as a piece of hollow profile which, as well as the support element 36, is elongated in the longitudinal direction L and which, in this case, is supported with reference to the lateral delimitation of step 22, it is say, blocks 24. Support is made in this place in a branch area 42 slightly inclined, despite having a path  approximately horizontal, of the lateral delimitation of step 22 respectively by an elastic seat element 44, which is also held by a drive gear corresponding in the support element 38. In the direction lateral with reference to the longitudinal direction L the step plate support with bearing structure 28 respectively by a transverse support arrangement 46 which is You can recognize in more detail in Figures 6 and 7.

This transverse support arrangement 46 it comprises a first support zone 48 in the lateral delimitation from step 22, in fact, in the form of a branch 50 thereof, approximately vertical, however, tilted slightly towards The outside and up. A second support zone 52 is configured on each of the step plates with structure bearing 28 on the support element 38. This second support zone 52 comprises a lateral area 54 also approximately vertical, however, in this case, tilted slightly upwards and inwards, that is, in the direction of lane 18. The two support zones 48, 52 are located, in the state of installation of the step plate with bearing structure 28, by way of wedge with reference to each other, so that they enclose a space intermediate 56 each other that decreases down by way of cradle.

It is provided assigned to each item step with bearing structure 28 also a support element 58 that is available or that has to be located in this intermediate space 56. This support element 58 has, on the one hand, an element additional seat elastic 60, which rests directly on the first support zone 48, that is, in one of the blocks 24 that placed opposite. A part of the body 62 of the element of support 58 which, by way of example, is also manufactured as a piece with a hollow profile, it is also supported by the second support zone 52, it is that is, the side 54 of the support element 38. On this side 54 and the body part 62 respectively formations of toothed 64, 66, which are elongated in the longitudinal direction L and presenting transversely to the longitudinal direction L, that is, approximately in the direction of height, a plurality of jagged projections or cavities, sequentially. By therefore, the support element 58 can be arranged on the side 54 of the support element 38 in different locations, where, during this arrangement, then the two formations of toothed 64 and 66 to a mutual gear. Once produced this gear, virtually no displacement of the support element 58 in the height direction with reference to support element 38. To immobilize a support element 58 in a location selected in the support element 38, is provide one or more retention elements 68. These are can be inserted through grooves 70 as a groove and interruptions 72 located of course correspondingly in the seat element 60, in recesses 74 as a groove in side 54 of support member 38, where, at the location fully inserted, shown in Figure 6, a lace flange 76, which is provided in the or each element of retention 68, embraces side 54 or support element 38 and, by therefore, secures the retention element 68 against an extension. To release this gear, it can be grasped laterally in the support element 38 configured as a hollow profile piece with a hand or a tool and the lace flange can be moved 76 to an alignment with the remaining area of the element of retention 68, so that it can be removed after location shown in Figure 6 and therefore it can be release the retention of the support element 58 on an assigned plate passing with bearing structure 28.

By the location that can be selected from support elements 58 in the assigned step plates with bearing structure 28 in different height situations, it is done possible to vary the entire width of a construction group that comprises a step plate with bearing structure 28 and an element support 58, in this case, the width refers to the direction longitudinal L. Therefore, it can be adjusted easily too  the lateral support length at variable separations between the lane 18 and the lateral delimitation of step 22. This has a importance particularly when renewing or reforming the railway installation 12 and, after the renewal of the bed of gravel, by way of example, does not reach the same location lateral, lateral refers again to the longitudinal direction L. Then, it is possible by a modification of the situation of support elements 58 in the assigned step plates with structure bearing 28, make an adaptation of corresponding length, so that, in this case, you can also get a installation situation without clearance in the case of different step plates with bearing structure 28. The support is produced both with reference to lane 18 and with reference to the lateral delimitation of step 22, respectively by elements seat elastics 34, 44, 60, by way of example, manufactured to from a rubber material, which, therefore, also hold fixedly on an assigned step plate with bearing structure 28 and  They are not inserted as separate construction parts.

Each of the step plates with structure bearing 28 further comprises between support elements 36, 38, with which the seat or support is made with reference to the rail 18 and the lateral delimitation of step 22, two support elements additional 78, 80. These extend between the two elements of support 36, 38 and are fixedly attached thereto, by way of for example, by welding, riveting, adhesion or otherwise. The support elements 78, 80 essentially elongated in shape transverse to the longitudinal direction L hold each other in the represented example two overcoming elements 82, 84 which, by thus, they exceed the intermediate space between the two elements of support 36, 38, on the one hand, and support elements 78, 80, by other side. The support elements 78, 80 form with the elements of overcoming 82, 84 surface areas that have a transition flush with each other, so that in the area between the two elements of support 36, 38 an approximately flat structure is produced of the step plates with bearing structure 28. By setting arrangement or also the dimensioning and conformation of support elements 80, 78, on the one hand, and the elements of overcoming 82, 84, on the other hand, each step plate with structure bearing 28 forms a recess for accommodation of lanes 86. It is that is, the support elements 78, 80 mesh with their zones lower observed in height direction respectively in boxes between sleepers 88 formed between two sleepers 14. By Therefore, the building space that is arrangement in the direction of height and, however, due to the possibility of using support elements 78, 80 that they build more solidly, a high capacity of load on the plates with bearing structure. Plates step with bearing structure 28 not only rely directly on the sleepers 14 and also on the material surrounding the sleepers 14, that is, by way of example, a gravel material, but, they exceed the area between lane 18 and lateral delimitation from step 22. Therefore, the installation location of the plates step with bearing structure 28 can be obtained completely independent of the conformation of the sleepers and, in addition, of totally independent form of conformation or accumulation of the material surrounding the sleepers 14. However, to be able to locate the step plates with bearing structure 28 thereof way as represented in the figures, they present form assigned to each individual support point 20, which immobilizes the rail 18, in the support element 36 a recess 90 which is you can recognize in Figure 5, in which the area is then housed of the individual support point 20, which is located on the external side of lane 18. The recess 90 is particularly sized in the longitudinal direction L so that neither light displacements of a step plate with structure bearing 28 in this longitudinal direction L can lead to a contact between the support element 36 and the support point individual 20. However, since it cannot be excluded that, with unfavorable circumstances, a displacement occurs excessive of that kind however you have to take care of it avoid electrically conductive contact between the step plate with bearing structure 28 and individual support point 20, as well as also lane 18, is responsible for electrical insulation in the recess area 90. This can be provided, by way of example, because the elastic seat element 34 which, so In addition, it produces electrical insulation between the element of support 36 and lane 18 is configured integrally with an isolation zone comprising, by way of example, several isolation lobes, which meshes in recess 90, which surrounds, during the application of a step plate with bearing structure 28 on lane 18, the area that engages in recess 90 of the individual support point 20 and therefore isolates it also with reference to support element 36, even when it is due produce excessive displacement. To get, despite that, also in this state an access to a respective support point individual, this isolation zone can be provided with slot-like openings, to be able to grab through the Same with a tool.

In addition, it is recognized above all in Figures 2 and 3 that the dimensioning of the step plates with structure bearing 28 in the longitudinal direction L of the passage device rail 10 is such that between pass plates with bearing structure 28 directly adjacent a space is created intermediate 92 reduced in the range of 2 to 4 cm. Each one these step plates with bearing structure 28 are immobilized with respect to its situation in the longitudinal direction L plus or least in a limited space, in fact, immobilized because the area located outside lane 18 of the respective Naughty 14 has to be housed in the housing recess of sleepers 86. However, also in this case, as you can recognize in Figure 4, fundamentally a certain movement slack. The length of the step plates with bearing structure 28 in the longitudinal direction L, therefore, not it is necessarily exactly the same as the division of the sleepers 14, that is, the separation between sleepers. This makes possible use step plates with bearing structure 28 designed from the same way, by way of example, in the outer zone of the curve and also in the inner zone of the curve, where they will adjust then, due to the curvature given, respectively intermediate spaces 92 different. Nor are manufacturing tolerances on the plates step with bearing structure 28, on the one hand, and in the installation rail 12, on the other hand, can lead to deformations, and that there is always a sufficient intermediate space 92 between plates step with bearing structure 28 directly sequential.

As explained above, the plates passing with bearing structure 28 of the first group 26 form only the overcoming between the two seating areas in the lane 18, on the one hand, and the lateral delimitation of step 22, on the other side. To make available a surface on which you can driving or walking or that can be used in another way, is provided a second group 94. This comprises a plurality of plates of cover passage 96. Also cover passage plates 96 are sequentially located in the longitudinal direction L, of so that in the longitudinal direction L, along the entire length of the railway passage device 10, a essentially closed surface. Thus, in this case, the cover passage plates 96 are joined directly. In this case, it should be emphasized that in Figures 1 and 2 it has to be located between the two cover passage plates 96 represented a plate additional cover step which, however, has been omitted by Drawing motives The division of the cover step plates 96 in the longitudinal direction L is independent of the division of step plates with bearing structure 28. The small ones intermediate spaces formed between the step plates with bearing structure 28 individual do not impair the ability to load.

The cover step plates 96 of the second group 94 are structured from an elastic material or flexible. In this case, the use is particularly appropriate of rubber waste granulate, which is fused by a binder, by way of example, polyurethane, with the use of pressure and high temperature and therefore produces very stable, which in particular can also be exposed to efforts during driving on them. Of course, these may be provided, on its surface 98 discovered towards above for the use of a structuring that makes available a desired adhesion.

In Figure 5 it is recognized that these plates of cover passage 96 are formed in its terminal zone 100, which is it has to be located near lane 18, so that they grab the rail head 104 below with a clamping boss 102, so that they are permanently strained in that place and they are also held in height direction. In its 106 terminal area that you have to locate near the lateral delimitation of step 22, the cover passage plates 96 are molded in such a way that, by one side, they sit on an additional branch or a step 108 of the assigned blocks 24 and, on the other hand, are supported by lateral direction in a side surface area 110 that is extends approximately horizontally and, in a given case, it put in contact with it in that place. In Figures 1 and 5 it is further recognizes that cover passage plates 96 are molded in its lower area in such a way that they are adapted to entire contour of the step plates with bearing structure 28 and particularly grab in the space formed between the two support elements 36, 38 and mesh with the support elements 78, 80 and the overcoming elements 82, 84. Therefore, the plates cover pitch 96 are essentially positioned with all the surface on the step plates with bearing structure 28 and are retained by this conformation also adapted so transverse to the longitudinal direction L with reference to the step plates with bearing structure 28.

To also obtain a fixed connection of the deck cover plates 94 individual to each other, is provided,  as can be clearly recognized in Figure 1 and Figure 2, an arrangement of tension elements 112. This extends in the longitudinal direction L along the passage plates of cover 96 or through an opening provided respectively in the same. The arrangement of tension elements 112 may comprise a plurality of tension bars 114, where the length of these tension bars 114 is adapted to the length of the cover passage plates 96 in the longitudinal direction L, so that respectively a tension bar 114 of this type links a cover passage plate 96 with a passage plate of cover 96 directly next or tension bar 114 which go through it. In the two terminal areas that are located in the longitudinal direction L of the interconnection formed in this way cover passage plates 96, can then be performed, by way of for example, by the arrangement of tension elements 102, also a link to the background, by way of example, with a respective sleeper 14. In this case, you can use clamping angles or Similar. Thus, it is not only produced by the provision of tension elements 112 a fixed interconnection of the plates cover step 96 of the second group 94, but simultaneously you also get a situation setting in the direction longitudinal L, as well as a protection against takeoff unwanted In this document, it should be noted that, of course, also depending on the width of the cover step plates 96 transverse to the longitudinal direction L, the arrangement of tension elements 112 may comprise several such groups of tension bars 114 laterally adjacent.

From the preceding description, recognize that, with this configuration of the passing device rail 10, fundamentally no interconnection is created fixed between the cover passage plates 96 of the second group and step plates with bearing structure 28 of the first group 26. Rather, it sits loosely on a first group 26 a second group 94. The second group 94, which puts layout the usable surface, is held, on the one hand, by its own weight, on the other hand, by the grip below the head of lane 104 and, in addition, by the link to the bottom that has been mentioned above, on the step plates with structure bearing 28. This simplifies the assembly of a passing device rail 10 according to the invention, since the plates 28 and 96 can be placed independently of each other and, of course, it also simplifies the disassembly of a passing device rail 10 according to the invention, by way of example, for performing maintenance work on the installation railway 12.

In the railroad passage device 10 which is described above, cover passage plates 96 of second group 94 essentially serve to make available the surface with the desired surface properties, that is, elasticity properties and adequate friction values. Without However, they do not have to be sized and configured in such a way. so that they also hold the entire load and support towards the bottom. This is the objective of the step plates with bearing structure, that can be configured for this, on the one hand, from suitable materials and, on the other hand, with a conformation adequate, where, however, in this case, you don't have to have consider certain surface properties. Therefore for Of course, it is also possible not to assemble the step plates with bearing structure 28 of a plurality of profile supports hollow, by way of example, structured aluminum, but put arrangement thereof as integral casting parts, by way of example, concrete casting parts that, of course, also They can be armed according to existing requirements. Also in the configuration of the step plates with structure bearing 28, for example, of concrete material, can be perform transverse support in the lateral delimitation of the passage 22 by the transverse support arrangement 46 described above previously in detail with reference to Figures 6 and 7. During the production of the step plates with bearing structure 28 can be molded therein, by way of example, the formation of toothed 64. Of course, a provision of Transverse support of this type also when, by way of example, only molded passage plates of material of concrete, that is, without any additional cover layer, and they must also make available the usable surface.

In addition, it is assumed that the device railway passage 10 according to the invention, as already mentioned mentioned at the beginning, it can not only be used in areas adjacent sides, that is, where a roadway reaches the railway installation 12, but, that such a structure It can also be selected in the area between the two lanes 16, 18 although, in this place, the issues mentioned above regarding the effort.

In Figures 8 and 9 a modified configuration of a rail crossing device 10. This coincides in essential aspects with the one described previously, so that, then, it will focus more on The essential differences. First of all, it is recognized above all in Figure 9 there is a difference especially in the configuration of the support element 38 to be located Away from the rails. While in the configuration that has been described above the same way, together with the element of support 36 that has to be located near the rails, an area open recess, which makes available with surfaces of the support elements 78, 80 and the elements of  overcoming 82, 84 the entire essential seating surface that holds the cover step plates 96, in the configuration shown in Figures 8 and 9, the support element 38 is constituted in such a way that it essentially does not stand out from the seating surface 150 made available by the elements of support 78, 80 and overcoming elements 82, 83, 84 and that puts available a seating surface 152 that is aligned so flush with it. That is, a step as a step, in this In this case, it is only available in the nearby terminal area of the rails by the support element 36. With its terminal area 106, which has to be located respectively away from the rails, a cover passage plate 96 extends outward, more beyond the seating surfaces 150, 152 that meet together flush, where it then contacts the area of lateral surface 110 in the lateral delimitation of step 22. In this area of mutual contact, lateral delimitation of step 22 or a respective block 25 thereof presents a cavity 154 as a groove and extending in the direction longitudinal lanes L, in which you can engage a clamping projection 156, protruding outward, of a cover passage plate 96. Therefore, the passage plates of cover 96 are held in the height direction both in your area terminal 100, which is located near the lanes, as in your area terminal 106, which is located far from the rails, by dragging form, in fact, with reference to lane 18, on the one hand, and with reference to the lateral delimitation of step 22, on the other hand. By of course, the conformation of the lateral delimitation of step 22 in this configuration could also be the way it has been described above with reference to Figures 1 to 7, of so that, in this case, there is no drive gear so in the terminal area away from the rails. Finally, you could also take care that only in the terminal area away from the rails of the deck passage plates 96 there is this gear with drag shape while it does not exist in the terminal area that is located near the lanes. Even when a drive-shaped gear acts in both terminal zones of this type in height direction, it can be done during the assembly of a railway passage device 10 simply because the cover step plates that generally they can be elastically deformed they are deformed first place with the use of corresponding tools during the placement, so that later, with the lace action, they engage in the notches or cavities.

In the case of this configuration shown in Figures 8 and 9, an additional configuration difference described above consists of the union of the support elements 36, 78 and 80. It is recognized in the representation of Figure 9 that the support element 36, in this case, is extends beyond a partial section of the surface that is discovered upwards of the support elements 78, 80 and that is welded in these areas of contact edges 158 formed in this area with the mimes, essentially in shape transverse to the longitudinal direction of the rails L, so therefore, it presents welding joints that extend in this address. In addition, a junction section 160 is provided which hugs down support elements 78, 80 in their areas terminals, which are located near the rails, or that extends along them, which is also welded in its areas of edge or edge 162, which have a path approximately towards below, with support elements 78, 80. A welding joint Additional 164 is formed so that it extends in the direction longitudinal L in the lower terminal area of this section 160

You can recognize in Figures 10 and 11 a modification of the configuration shown in Figures 8 and 9. In this case, a difference consists primarily of the configuration of the lateral delimitation of step 22. While in the configurations described above the same it comprises a plurality of blocks 24 molded from a concrete material, in this case, elements of lateral delimitation 170 elongated in the longitudinal direction L structured of a metal material, by way of example, steel. These are designed, by way of example, by welding a plurality of molded plate elements, such that correspond in its cross-sectional contour approximately with  the outline, which previously could also be recognized, of the 24 blocks molded from a concrete material. That is to say, fundamentally you can keep the same functionality that has been described above, however, with the structure of these Elements of a metal material. As well as blocks 24, lateral delimitation elements 170 can be immobilized by the use of a mortar or setting bond material fast on a background prepared, by way of example, a fund of concrete. In this case, it should also indicate that the elements of lateral delimitation 170 can of course also present the groove-like cavity 154, as described above. In addition, it is assumed that the configurations that are represented in Figures 8 to 11 they can be configured particularly also with respect to the support with reference to the respective lane 16 or 18, the same as the configuration represented in the Figures 1 to 7. That is, therefore, particularly also the elastic seat element 34 can provide not only a seat elastic and therefore also an insulation with reference to respective lane 16 or 18, but you can also provide with sections correspondingly molded therein an insulation electrical which, in a given case, is necessary between the element of support 36 and the respective area of an individual support point 20 that gears in it. In addition, it should be noted that, in all configurations represented or described, surfaces or zones of surface of the step plates with bearing structure 28, on which cover passage plates 96 sit, by way of example, they can be made rough, by way of example, by sandblasting, to perform a force closure here by improved friction between cover passage plates 96 and step plates with bearing structure 28 and, thus, counteract a displacement of the cover passage plates 96 in the longitudinal direction L that is possibly produced by a oblique performance of force during a crossing.

An additional possibility to counter this displacement is described below with reference to Figures 12 and 13. Although a plate is shown in Figure 12 step with bearing structure 28 of the configuration shown in Figures 8 to 11, of course, a anchor arrangement 172, shown there, in the step plates with bearing structure 28 represented in the Figures 1 to 7.

It is recognized in Figure 12 that the provision anchor 172 comprises an anchor element 174 by way of plate, which is essentially configured as a clamp, is that is, it is configured in a U-shaped cross section and which, in this way, embraces the overcoming element 83 as a plate that is placed between the two overcoming elements 82, 84 that They can be recognized and held in it. Particularly, it select the extension length of the anchoring element 174 of such that it corresponds to the extension length of the overcoming element 83 between the two support elements 78, 80, so that the anchoring element 174 can hardly be move between support elements 78, 80 in the direction longitudinal L, that is, not in the direction of extension of the provision of tension elements 112. To ensure a increased binding stability of the retention element 174 in the overcoming element 83, joints can be used here of threads additionally represented. Therefore, I don't just know ensures a fixed interconnection in the longitudinal direction L, otherwise, an upward lift is also avoided. On the side upper of the anchoring element 174 an element is immobilized coupling 176 configured with internal thread in its two zones terminals located in the longitudinal direction L, by way of example, by welding.

In this coupling element 176 you can screw two tension bars 114 of the element arrangement voltage 112, respectively configured with approximately half length, to bind in this way a plate of roof passage 96 located on the step plate with structure bearing 28 shown in Figure 12 with the anchoring element 174 and, thus, on the step plate with bearing structure 28. This cover passage plate 96 is shown in Figure 13. It is recognized that it essentially presents the opening 178 as a hole that extends in the longitudinal direction L, which is necessary for the passage of tension bars 114. In its central section, that is, that is placed on the element of anchor 174 or coupling element 176, this step plate of cover 96 has a recess 180 open downwards. The it is sized in such a way that it houses, with the location of  this cover step plate 96 on the step plate with bearing structure 28 shown in Figure 12, the sections of anchor arrangement 172 protruding from the seating surface 150. In this way, it is secured, so other, a seat contact on the entire surface between the plate cover passage 96 of Figure 3 and the passage plate with bearing structure 28 of Figure 12.

Therefore, before the two are screwed tension bars 114, which can be recognized in Figure 12, in the coupling element 176, the passage plate of cover 96 on the passage plate with bearing structure 28. Then, the two tension bars 114 are passed from the two ends of the cover passage plate 96 that are located in longitudinal direction through the respective section of the opening 178 that is placed in that place and curled with their threaded ends in the coupling element 76. Subsequently,  on both sides of the cover passage plate 96, in this case already immobilized, cover passage plates 96 can be placed additional and then join by thread with tension bars 114 that have to pass through them in the bars of tension 114 that are already existing and screwed into the element of coupling 176. This process can be continued in both addresses, until the desired number of license plates is placed cover step 96.

For reasons of stability, this provision of anchor 172 is preferably provided in a central area of a railroad crossing device 10. Fundamentally, it also can conceive, by way of example, step devices 10 longer railways, provide various provisions of anchor 172 of this type in positions that are placed with a separation from each other in the longitudinal direction L.

Particularly, for the solidarity performance of anchor arrangement 172, shown in Figure 12, and the anchor, which acts in the two terminal zones 100 and 106 of the cover passage plates 96 with reference to the bottom, is performed a very stable hold of the cover base plates 96 also in the terminal areas of the railway crossing device 10, so that, in that place, in a given case, it is not necessary no other additional measure, to get an anchor with background reference. However, of course, it is possible provide in this place additional elements, with which they are particularly secured the terminal areas also against a takeoff.

In Figures 14 and 15 a modified configuration of a transverse support arrangement 46, as can be provided, by way of example, assigned to the bearing plates with bearing structure 28 shown in Figures 8 to 11, however, of course, you can also use in the configuration shown in Figures 1 to 7.

Toothed formations are recognized again 64, 66 that have to take a gear to each other, where the toothed formation 64 provided in the support element 38 is approximately totally continuous in the direction of height. The toothed formation 66 that is provided in the element of support 58 presents two groups 182 of teeth or nerves that are place with a separation from each other, where each of these groups 182 may comprise, by way of example, two teeth or nerves. The zone between these two groups 182 is formed essentially flat and it is not placed in a gear with the toothed formation 64 in the support element 38. In this way, it is ensured that also with reduced manufacturing tolerances can avoid a redundant determination for too many protrusions or cavities that mesh with each other.

In addition, it is recognized in Figure 14 that in elastic seat element 44 of support element 38 is molded a shoulder 184 that engages in an opening not shown of the support element 38 and thus secures the element elastic seat 44 against displacement with reference to support element 38. It is assumed that it can also be provide a similar clamping formation, which acts with drag in the direction of travel, in the case of elastic seat element 34 of support element 36 as well as also in the case of the seat element 60, which is held by the gear with form drag on the support element 58.

Finally, it should be stated again that, by Of course, different configuration aspects can be combined of the different configurations described above. In this way, of course, the provision of tension elements 112, in the configuration described with reference to Figures 1 to 7, with reference to at least one plate passing through bearing structure 28. The same, of course, also It is valid for the different elastic seat elements, which are they can also insure against displacement with reference to support elements or support elements, which respectively they house them, by a gear with drag of form correspondent. Of course, they can also be used in all configurations of the step plates with bearing structure 28 or cover passage plates 96 the lateral delimitations of the step 22 that are not structured from a concrete material, but, of a metal material.
