i of a carriage body which is suitable to receive loose material.

In accordance with AT-PS 378 973 aninstallation movable on a track is already known, having a plurality of such loading carriages which are coupled to each other into a drawn formation. These have a conveyor belt arrangement both for the through transportation and also the storage of loose material, which arrangement is composed of a conveyor belt arranged in the base region of an elongated carriage body and of a transfer conveyor belt adjoining thereto in the conveying direction. To supply the various conveyor belt drives, each loading carriage has its own internal combustion engine. All the drives for the conveyor belts of the various loading carriages are connected with a central control unit, which is arranged in an installation for the stabilization of the foundation of the track. Owing to the a transfer conveyor belt projecting over the buffer breast, a problem-free transfer of the loose material from the said installation for the stabilization of the foundation of the track to the following loading carriage is possible. Here, with the conveyor belt arrangements of the individual 0* loading carriages running rapidly, the loose material is transported to the last loading carriage and is stored therein at a slow speed of revolution of the base conveyor belt. The transfer conveyor belt associated therewith is not set in operation here. As soon as this loading carriage is completely full, the slow revolution of the base conveyor belt is stopped and at the same time the speed of revolution of the base- and transfer :onveyor belts in the preceding loading carriage is reduced for the storage of the continually accumulating loose material.

Such an installation, movable on rails, is also known in 3 accordance with DE-Gbm 88 13859 to receive and transport loose material, in which each loading carriage merely has one conveyor belt situated in the base region of the carriage body. This belt projects with its front end region in the conveying direction beyond the buffer breast of the loading carriage and is also arranged lying higher compared with the opposite conveyor belt end. In this way, the loose material is transferred from this base conveyor belt directly onto the base conveyor belt of the next loading carriage. The conveyor belt is arranged entirely within the carriage body, which is connected with the framework of the *0e* ~loading carriage by means of corresponding supports.

U.

The object of the present invention lies in creating a loading carriage, travelling on rails, of the type described in the introduction, which with reduced structural expense is of particularly simple construction.

This object is solved according to the invention in that the conveying device and a support frame supporting it are constructed so as to be broader than the carriage body in its lower end region and that at least a lower region, adjoining the conveying device, of the side wall of the carriage body running in the longitudinal direction of the S carriage is constructed so as to be detachable or respectively orientable .about an axis running in the longitudinal direction of the carriage. This special construction .has the advantage that a carriage body which is constructed particularly simply with four flat walls is able to be used without a base surface. Through the broader construction of the conveying device, between the latter and the carriage body, a reliable seal is able to be produced without any extra structural expenditure, wherein the lower ends of the walls of the carriage body are arranged immediately above the conveying device. The detachable or respectively orientable construction of the lower section of each side wall permits, within a very simple solution, a problem-free and rapid dismantling of the old, used conveyor device, and the installation of a new one, despite the broader construction.

A particularly preferred further development of the invention lies in that each side wall of the carriage body, running in the longitudinal direction of the carriage, is mounted in its lower end region so as to be orientable on the support frame about an axis running in the longitudinal direction of the carriage. Thereby, on the one hand, a fixed anchoring of the side walls on the support frame is ensured, and, on the other hand, a rapid exposure of the lateral end regions of the conveyor device for its unimpeded dismantling or respectively installation.

The mounting of the side wall, having the axis, is arranged at a distance therefrom in the transverse direction of the carriage, in accordance with another variant of the invention. Hence, the lateral end regions of the conveyor I: device, lying outside the carriage body, are already exposed through a relatively small movement of orientation of the o o S side walls, so that the conveyor device is accessible in an unimpeded manner over its entire width.

The side walls running in the longitudinal direction of the carriage may advantageously be connected on their outer side in each case with support strips, at a distance from each other, running vertically to the conveyor device which support strips in their lower end region are supported by means of the mounting on the support frame. These supports make it possible to use side walls which are constructed in the simplest manner in laminar form and which are able to be reinforced by means of the supports and despite the orientable mounting are able to be connected with the support frame in a stable manner.

The side walls are substantially simpler and above all are orientable avoiding torsional forces if, in accordance with a further variant construction of the invention, each side wall which is orientably mounted on the support frame is formed from a plurality of side wall pieces, preferably three, arranged in series in the longitudinal direction of the carriage.

The orientably mounteo side walls of the carriage body are advantageously connected with each other in a detachable manner by means of transverse struts in their upper end regions. Thereby, the laterally orientable side walls are able to be locked in a simple manner and are able to resist the increased lateral pressure without difficulty when the loading carriage is full.

According to another advantageous embodiment of the invention, provision is made that the lateral walls are arranged running in an approximately vertical plane, or Srespectively a plane perpendicular to the conveyor device and with their lower ends at a distance from the conveyor device, wherein on the inner side of the side walls and also in the region between the side wall and the conveying device a lining of elastic material is attached.

By means of the elastic lining, the side wall, which is of S- relatively thin construction, is reliably protected against wear, wherein by distancing the lower end of the side wall a disadvantageous friction with the conveyor device is ruled out.

In accordance with another advantageous variant of the invention, a lower part of the lining, adjoining the conveyor device, is constructed so as to be separate from the rest of the lining and so as to be displaceable in the direction towards the conveyor device. By means of these structural features, in a particularly simple manner a splitting arising through wear of the lining, which may touch the conveyor device for a tight seal, is able to be eliminated.

In accordance with a further possible construction of the invention, a lower part of the side wall of the carriage body, adjoining the conveyor device, is constructed so as to be orientable about an axis running in the longitudinal direction of the carriage. Through this step, with a reduction of the necessary expenditure of force, merely a part of the side wall .is to be constructed so as to be orientable for a dismantling or respectively installation of m the conveyor device on the base side.

*e *9 r A furthe'r, preferred form of embodiment of the invention lies in that the support frame, which is connected with the side walls or respectively with the carriage body and the conveyor device, has downwardly projecting supports, which are detachably connected with the loading platform of a platform wagon. A support frame provided with such features is able to be placed in a particularly advantageous manner onto platform-shaped wagons avoiding costly adaptations.

Thereby, platform wagons which are already in use are able to be equipped with the suport frame, the conveyor device and the carriage body, and are able to be used as loading carriages.

According to another development of the invention, provision is made that the supports are constructed for a position of the support frame which is oblique in the longitudinal direction in relation to the loading platform of the platform wagon with differing length, wherein under, the higher end region of the conveyor device on the base side a lower end region of a transfer conveyor belt is arranged, projecting over the buffer breast. Owing to the oblique position of the support frame, the transfer conveyor belt can be arranged with its lower end beneath the higher end of the conveyor device, without a structural alteration to the loading platform being necessary for this.

In accordance with a further variant of the invention, the transfer conveyor belt may be mounted so as to be orientable on the platform carriage about an axis running at an angle to the plane of the conveying device. Thereby, in a simple manner, even in the case of curves in the track a centering of the upper end of the transfer conveyor belt is possible over the carriage body end of the loading carriage arranged in front.

o~eoQ Another advantageous embodiment of the invention also lies in that the carriage body and the support frame are constructed so as to be narrower than the width of the platform wagon, for the formation of a gangway on the two Slongitudinal sides of the carriage. These gangways permit an unimpeded and safe movement of a supervisory person and also make it possible for the latter to change over without difficulty to the adjoining loading carriage, without thereby arriving into the danger area of a neighbouring track.

A particularly advantageous further development of the invention lies in that on the end of the carriage body lying opposite the orientably mounted transfer conveyor belt, and/or at the upper end of the transfer conveyor belt, a centering device is arranged for arrangement against an orientably mounted transfer conveyor belt or respectively against the carriage body of a further loading carriage. By means of such a centering device, it is ensured that even in the case of curves in the track, automatically a centering of the upper end region of the transfer conveyor belt centrally over the associated end region of the carriage body takes place.

In accordance with a further variant of the invention, this centering device is constructed in the form of two support rollers, spaced apart from each other at a distance corresponding at least to the width of the transfer conveyor belt, which support rollers are mounted so as to be rotatable on the carriage body about an axis running transversely to the longitudinal direction of the carriage and horizontally, and in their outer end regions in each case are connected with a flange having a greater diameter than the support rbllers. Such support rollers ensure a reliable centering of the transfer conveyor belt and also make possible its support to relieve the load of the bearing site arranged in the lower end region. The flange provided respectively in the outer end region of the support rollers provides for a problem-free centering even in tight curves ~in the track.

o0 Finally, in accordance with a further variant embodiment of the invention, the centering device is constructed in the form of two rollers, connected with the carriage body and running in a plane parallel to the plane of the transfer conveyor belt, of .which smallest distance from each other, o running in the transverse direction of the carriage, o0 corresponds at least to the width of the transfer conveyor belt. This centering device is particularly simple in ooooo: S construction and provides for practically no friction to *:*out S: arise between the transfer conveyor belt and the carriage body end of the adjoining loading carriage.

e• S, The invention is described in further detail hereinbelow with the aid of two example embodiments, represented in the drawing, in which: Fig. 1 shows a side view of a loading carriage for loose material, which is coupled with several such loading carriages to form a loading unit, Fig. 2 shows an enlarged view of the loading carriage in accordance with arrow II in Fig. 1, Fig. 3 shows an enlarged detail cross-section through a side wall, constructed according to the invention, of the loading carriage in accordance with arrow III in Fig. 1 and Fig. 4 shows a partial view, running in the longitudinal direction of the machine, of a, further example embodiment of a loading carriage constructed according to the invention, wherein only the end region of the side wall is constructed so as to be orientable.

The loading carriage 1 for loose material or the like, which can be seen in Fig. 1, consists of a platform wagon 3, having a loading platform 2, with bogie travel gear 4 arranged on the end side. On the plaform wagon 3 there is a support frame 6, connected with a carriage body 5, in which Sframe a conveyor device 7 is mounted, adjoining the lower end of the carriage body 5. The support frame 6 has downwardly projecting supports 8, which are detachably connected with the loading platform 2 of the platform wagon P gO e 2 by means of screw connections 9. The carriage body 5 is *om composed of two side walls 11, running in the longitudinal direction of the carriage and formed respectively from three side wall pieces 10 arranged in series, and is further composed of end walls 12, connecting the latter with each other and running transversely. The side walls 11, running vertically or respectively arranged perpendicularly to the Sa plane of the conveyor device 7, are connected in the region of their outer side-with support strips 13, spaced apart from each other and running vertically to the conveyor device 7. In the adjoining end region of two side wall pieces 10, respectively two such support strips 13 are arranged so as to be immediately adjacent.

The supports S connected with the loading platform 2 are constructed with differing length for an inclined position of the support frame 6 in relation to the loading platform 2 in longitudinal direction. Under the higher end region of the conveyor device 7 on the base side, a lower end region

I:

14 of a transfer conveyor belt 16 is arranged, projecting over a buffer breast 15. This transfer conveyor belt is mounted so as to be orientable on the platform wagon 3 about an axis 17 running at an angle to the plane of the conveyor device 7. In the upper drop region 18, a drive 19 is arranged to produce a revolving movement of the transfer conveyor belt 16, indicated by arrows 20. In the drop region 18, this belt rests by means of a centering device 21 on the carriage body 5 of a further loading carriage 1 arranged in frort in the conveying direction. The conveyor device 7, which is constructed as an elastic and endless conveyor belt is movable by means of a drive 22 wi-h its upper belt or 9** respectively upper section in the conveying direction indicated by the arrows 20. In the region of the rear end, in conveying direction, of the loading carriage 1, which is illustrated in its entirety, a transfer conveyor belt, for example -a ballast cleaning machine, is indicated by dot-and-dash lines.

As can be seen in particular in Fig. .2 and 3, the conveyor device 7, constructed as a conveyor belt-, and the support frame 6 supporting the latter, are constructed so as to be broader than the carriage body 5 in its lower end region.

The two side walls 11 are orientably connected with the support frame 6 in each case in their lower end region about an axis 23 running in the longitudinal direction of the carriage. A beai ing 24 having these axes 23 is connected on the one hand with the upper end region.of the support frame 6 and on the other hand with the lower end of a support strip 13, at. a distance from the side wall 11 in the transverse direction of the carriage. The orientably mounted side walls 11 of the carriage body 5 are dezachably connected with each other in their upper end in the region of the support strips 13 by transverse struts 25 (see Fig.

2).

To form a gangway 26 on both longitudinal sides of the

II

carriage, the carriage body 5 is constructed so as to be narrower than the width of the plaform wagon 3. The centering device 21 connected with the rear side wall piece is constructed in the form of two support rollers 27, which are respectively mounted so as to be rotatable about an axis 28 running transversely to the longitudinal direction of the carriage and horizontally. The conveyor device 7 ha-s respectively in its longitudinal end region a deflection roller 30 mounted on the support frame 6 and having an axis running transversely to the longitudinal direction of the carriage.

:0 As can be seen in particular in Fig. 3, the side walls 11 are arr.anged running in an approxiately vertical plane or respectively a plane, perpendicular to the qonveyor device 7 and with their lower ends at a distance-from the conveyor device 7. On the inner side of the side wall 11, a lining 31 of elastic material, is provided. A lower part 32 of the lining 31 adjoining the conveyor device 7 is separate from the rest of the lining 31 and is constructed so as to be displaceable in the direction towards the conveyor device 7.

As a bridge between the lower and upper parts 32,33 of the lining 31, a sheet metal plate 34 is provided, which is detachably secured to the side wall 11.

.o In the production of the loading carriage 1 constructed according to the invention, in an advantageous manner platform wagons 3 which are already in service are also able to be used, wherein the. unit formed from the support frame 6, the conveyor device 7 and the carriage body 5 is connected by means of the screw connections 9 with the loading platform 2.

The transfer conveyor belt 16 is likewise detachably connected in the end region of the loading platform 2. This special construction means that the platform wagon 3 is able to be used in its original state, avoiding costly extra ,work. The lower part 32 of the linin .1 can be displaced in the direction towards the conveyor device 7 after wear and splitting, resulting therefrom, with a corresponding loosening of the sheet metal plate 34. Therefore it is ensured at all times that the ballast stored in the carriage body 5. can not flow out in this region. For the installation or respectively dismantling of the elastic conveyor belt of the conveyor device 7, firstly the transverse struts are loosened and then the side walls 11 are oriented outwards into the position indicated by dot-and-dash lines.

Through the arrangement of the bearing 24 which is staggered with respect to the side wall 11 in the transverse direction of the loading carriage 1, the lower edge of the side walls 11 is displaced outwards with the orientation movement, so that the conveyor belt 35 is able to be installed or respectively dismantled in an entirely unimpeded manner.

A loading carriage 36, illustrated in Fig. 4, is likewise composed of a platform wagon 37, a- support frame 38 connected therewiLh, with a conveyor device 39 constructed as a conveyor belt, and a carriage body 40. A transfer conveyor belt, which is arranged in an inclined manner, is not shown, for greater clarity. An. end wall 42 is connected respectively with side walls 41, running in the longitudinal direction of the carriage, in their front and rear end regions. A lower part 43 of the side wall 41 of the carriage body 40, adjoining the conveyor device 39, is constructed so as to be orientable about an axis 44 running in the longitudinal direction of the carriage. An upper part 45 of the side wall 4-1 is connected with support strips 46 secured to the support frame 38. The lower part 43 is arranged so as to be inclined with respect to the conveying plane of the conveyor device 39, wherein the conveyor device 39 is constructed so as to be broader than the distance from each other, running transversely to the longitudinal direction of the carriage, of the two lower end regions of the lower parts 43 associated in each case with a side wall 41. In the rear and upper end region, in the conveying direction, of the carriage body 40 a centering device 47 is provided. The latter is constructed in the form of two rollers 48 connected respectively with a side wall 41 and running in a plane parallel to the plane of the transfer conveyor belt, which rollers are provided to rest against the side walls of the transfer conveyor belt. The smallest distance of the rollers 48 with respect to each other, running in the transverse direction, of the carriage, corresponds at least to the width of the transfer conveyor belt. For the installation or respectively dismantling of the conveyor belt of the conveyor device 39, the lower parts S 43 of the side wall 40 are turned up (see dot-and-dash arrow). However,. it is likewise possible within the scope of the invention not to secure this lower part 43 orlentably, but rather to secure it detachably on the support strips 46.
