Description

Movable conveyor belt storage system, belt storage and transfer vehicles for such a movable conveyor belt storage system

The invention relates to a movable conveyor belt storage system with a tape storage, the tape storage downstream support structures for the conveyor belt and a movable transfer car with a deflection for the conveyor belt and a Aufnahmeschurre for the acquisition of degraded material, suitable for such a system tape storage and on a in the context of such a conveyor belt storage system particularly preferably usable takeover vehicles.

In US 2,925,901 a continuous conveyor system is described, which consists of a tape storage, nachgereihten scaffolds and a called "Hoppercar" takeover wagons.The takeover carriage takes over here by a tunneling or mining machine geschrämte or degraded material, in which case the with the However, in the case of relatively large-scale belt accumulators, such an approach can not be carried out arbitrarily, but rather for a new break-in and for a new burglary As a rule, a new section of the belt conveyor to be dismantled is completely dismantled and rebuilt at the new service station, which means a high disassembly and assembly effort and a relatively large loss of time.

Conveyor belt storage systems with a storage unit with downstream support frames are also described in GB 1391612, among others. A similar system with a conveyor belt storage system can be found in GB 1150696, in which the filling takes place with vehicles that can travel in the line. In particular, when reduced by relatively low flots the resulting spatial limitation high demands on the construction of such a movable conveyor belt storage system. As a rule, a tape storage with regard to its dimensions not be introduced into the degradable flute with much lower height, so that relatively large distances must be covered with the stored conveyor belt to allow the removal of the mined material. The correspondingly increased conveyor belt requirement leads to further enlargements of the dimensions in the known constructions.

Between the tape storage and the transfer car, which itself has a pulley for the withdrawn from the tape storage conveyor belt, appropriate supports for the conveyor belt must be provided. The scaffolds must therefore also be introduced into the flute to be dismantled. From DE-Al 38 37 986 a support frame for roll holder for upper and lower castor wheels can be seen for this purpose, in which the support bars in groups are telescopically slidable. Such additional devices can also be found, for example, in US Pat. No. 6,095,320, in which a storage system for load-bearing structures is described, in which the support frames are arranged with the longitudinal struts slidable into one another. To ensure the appropriate stability, the longitudinal struts are rigidly connected to a scaffold spar.

Finally, US Pat. No. 4,245,738 discloses a tunneling machine to which an extendable belt conveyor device is connected. The necessary for the support conveyor belt scaffolds can be removed here from a memory and are provided with floor plates to ensure a corresponding stability.

The well-known strip accumulators, transfer trolleys and support devices are generally not reducible in any way, so that in low-producing flots a correspondingly widest automated use is not readily possible. Also, the known devices are not flexible to the extent that in a change from one route to the next route a Ab- and a structure of the tape storage is unnecessary. Finally, the known transfer car for use in particularly low distances are not particularly suitable and limited in particular in the process in terms of their dome and Muldengängigkeit.

The invention aims only to provide a movable conveyor belt storage system and suitable elements for this, with which the use in particularly low distances is possible and even when driving crests and troughs can be passed through without difficulty. Furthermore, the invention aims to provide a movable conveyor belt storage system of the type mentioned, in which the ^■ change from one route to the next route without dismantling and construction of the conveyor system, and in particular of the tape storage can be made.

To achieve this object, the movable conveyor belt storage system according to the invention of the type mentioned above essentially consists in that the tape storage of at least two about a transversely to the strip running direction and the sole plane passing through extending axis pivotally interconnected segments and that at least a portion of the scaffolds in or is carried on the transfer car. Characterized in that the band memory has a plurality of segments, which in turn are hingedly connected to each other and pivotally connected to one another transverse to the strip running direction and the sole plane extending axis, the possibility is created, even in tight curves without breaking the tape storage a To ensure mobility of the entire system. The fact that now at least a portion of the scaffolding in or on the transfer car is carried along, the necessary for the extension of the conveyor belt supports are always taken to near the working face, so that a largely continuous replica of the support according to the dismantling progress successful without this long transport routes for the individual scaffolds are required.

Advantageously, the training is in this case made such that a part of the scaffolds extendable with the tape storage and the majority of the scaffolding in the transfer trolley in the height direction is raised and lowered stored.

A particularly suitable for the movable conveyor belt storage system according to the invention strip memory is inventively further developed so that the band memory has a plurality of segments, that at least two segments have a crawler, that the segments transverse to the strip running direction extending frame spars and that releasable locking members for the pivotable Connection of frame bars are provided. Of the individual segments should thus have at least two segments on a crawler track to ensure the appropriate maneuverability, the pivotal connection is ensured directly by appropriately trained releasable locking members, which can simultaneously form the pivot axes for pivotability. The design is advantageously such that the releasable locking members are formed by axially displaceable bolts or rods, which are axially dipping or dipping in bearing eyes, wherein the axes of the bolts or rods respectively represent the pivot axes. In each case one of the segments has the corresponding bearing eyes, whereas the adjacent segment has the releasable locking members, which can dive into the bearing eyes.

In order to be able to safely supply conveyor belts with particularly long distances, the design according to the invention advantageously has such an effect that at least one segment has bearings for accommodating rollers with an additional conveyor belt. It is thus also additional conveyor belt on separate roles already integrated with the tape storage carried and it must be used for the extension of the conveyor belt no additional device. The design of the band memory of individual segments allows individual segments to assign such additional functions and still ensure the necessary flexibility for driving through any routes.

Advantageously, the training according to the invention is such that the individual segments have in a box-shaped profile rails for cars with sliding pulleys for the stored band, which reach in locking the locking members in a mutually aligned position. In the respective operating position, the individual segments must be locked together and only in this position can be deducted from the storage conveyor belt. In this position, it must therefore also be ensured that the rollers required for the tension of the conveyor belt and the removal of the desired length on the conveyor belt can be moved with their corresponding carriages supporting the bearings of the rollers in the longitudinal direction of the belt store. The rollers themselves are arranged in the usual manner with different diameters each in movable scaffolds, wherein the band is guided around the individual rollers in the manner of a pulley, as corresponds to the known prior art.

The desired off-road capability and flexibility with tight curve radii can be achieved with advantage in that at least three articulated segments each have at least one crawler track. The articulation in any direction can be ensured in a particularly simple manner by virtue of the fact that the segments connected to one another in an articulated manner each have two locking members which can be actuated independently of one another outside the longitudinal center of the strip accumulator or the respective segment and in which the segments are each about the locked axis pivotally connected to each other, with the respective short- veninnere locked axle ensures the respective pivoting. The locking or the solution of the lock can be done in a particularly simple manner so that the locking members are formed by hydraulically actuated bolts, such training also ensures that correspondingly high forces can be safely absorbed by the locking members.

The transfer trolley particularly suitable for use in the movable conveyor belt storage system according to the invention, like other known trolleys, comprises, in addition to a frame and a chassis connected to the frame, in particular crawler tracks, and a deflection roller for a conveyor belt running below a trimming chute, further elements are preferred further developed that the frame is designed as a portal frame, on which at least one subframe for the support of support frames and / or a storage of the guide roller and / or the receiving chute is articulated supported. The formation of the frame as a portal frame makes it possible to suspend the subframe in a suitable manner and in particular to define in the manner of a three-point bearing in accordance with yielding manner, which allows a self-adjustment of the conveyor belt on the pulley. At the same time, such a suspension for driving allows to improve the Muldengängigkeit and to facilitate the driving over hills, as by the use of a subframe, a corresponding height adjustment relative to the portal frame can be achieved, which avoids collisions with the sole. Advantageously, the training is in this case made such that the subframe is mounted hanging on the portal frame, wherein preferably the subframe is adjustably connected in the height direction with the portal frame.

As already mentioned, a particularly advantageous suspension with the appropriate freedom of movement in the manner of a three-point suspension to achieve, with a particularly preferred construction is that the subframe on at least two hydraulic cylinder piston units and at least one further articulation point with at least two degrees of freedom of movement is connected to the portal frame.

For the safe storage of entrained by the transfer car to close to the working face Abstützgerüste the training is advantageously made so that the subframe in the longitudinal direction of the transfer trolley extending spars for receiving scaffolds, which is additionally provided with advantage a shelf for connecting rods for the scaffolds in which connecting rods can be connected to two locking points of the supporting frameworks via at least two locking members, in particular threaded bolts, which are offset in the longitudinal direction via the connecting rods. The arrangement of at least two longitudinally offset locking points allows here to connect the individual supports against tilting or pivoting secured together, so that can be dispensed with space-consuming floor panels and a larger number of supports without further teres can be carried along with the transfer car. The training is advantageously made such that the scaffolds are slidably mounted on rollers on the subframe in the longitudinal direction or conveying direction.

The invention will be explained in more detail with reference to embodiments shown schematically in the drawing.

In Fig.l further the extended route is denoted by 2, wherein the remaining between adjacent sections already ascended sections are designated 3.

Within the distance 2 is now a tape storage 4 can be seen, which has a plurality of crawler tracks 5. The crawler tracks are each associated with individual segments of the tape storage 4, wherein drums 6 are visible at the rear end, which contain additional conveyor belt rolled up.

Adjacent to the front end of the strip accumulator 4, a transfer trolley 7 is shown, which has a feed chute 8. The transfer conveyor indicated schematically at 9 at the rear end of the line driving or -wing machine 1 is in this case raised so far in operation that the from the Streckenvortriebs- or -gewinnungsmaschine 1 recovered material can be dropped on this conveyor 9 in the chute 8. The material passes in the sequence on a withdrawn from the tape storage 4 conveyor belt.

In the illustration in Figure 2, the movability of the conveyor belt storage system is indicated schematically. In the respective traversing position naturally no discharge of material and no Abförderung done, since here the tape is withdrawn in the tape storage 4 and overall the most compact length is taken. However, in order to ensure the corresponding curve, the locking members are hereby solved at the points schematically indicated at 10, wherein at the respective longitudinal center of the opposite points 11, the lock has not been canceled, so that here each pivot axis is formed, which ensures the curve. The crawler undercarriage of the transfer trolley 7 is denoted by 12 here.

In the illustration of Figure 3, a segment 13 of the tape storage 4 is now visible, which has locking members 15 formed by bolts 14. These bolts 14 of the locking members 15 are displaceable over hydraulic cylinder piston units 16 in the axial direction and can thus be inserted into corresponding bearing eyes 17, as can be seen in Figure 4, to form a pivot axis. The segment 13 additionally has a crawler undercarriage 5. The upwardly projecting frame spars are designated 18 and carry the respective locking members. In the box frame construction also tracks 19 for pulleys of a conveyor belt carrying car are visible, which are aligned in the respective locking position with the corresponding rails 19 adjacent segments 20. Such an adjacent segment 20 is shown in Figure 4, in which case the upstanding bearing the bearing eyes uprights are denoted by 21. The box structure leaves above here Rails 19 a sufficient space for the management of the stored conveyor belt.

In Figure 5, another terminal segment 22 of the tape storage can be seen, which in turn has a crawler undercarriage 5, in addition to the mounted in a carriage 23 guide rollers 24 for the stored tape. The drums 6 in turn carry roles. additional conveyor belt, which are indicated schematically at 25 and can be connected to the already in the memory tape to extend the stored tape as needed.

Here, the second movable on the rails 19 carriage 23 can be seen, which in turn has the guide rollers 24 for the stored conveyor belt. To maintain the desired belt tension to the transfer trolley 7 a not shown in detail via a guide roller 27 guided rope is provided which holds the carriage 23 of the conveyor belt, not shown under tension. The segment 26 in turn carries the actuated by the hydraulic cylinder piston unit 16 locking members 15th

In the illustration according to FIG. 7, the locking members 15 formed by bolts are now shown in their engaged position. The bolts 14 in this case pass through the bearing eyes 17 of adjacent segments and therefore form the corresponding locking or the desired pivot axis in the region of their ends. The hydraulic cylinder piston unit, which is provided for the actuation of the bolt 14, is again denoted by 16.

In Figure 8, the transfer trolley 7 is now shown enlarged, the recording chute is again denoted by 8. At the

At the top of the transfer carriage, connecting rods 28 are kept in stock, which subsequently connect to the connection. barter scaffolding 29 find use. The scaffolds 29 are stored on frame members 30 of the transfer car. The transfer trolley 7 has the already shown in Fig.l caterpillar 12th

In Figure 9 is schematically seen in the side view that with a correspondingly raised position of the frame members 30, the scaffolds 29 are lifted from the sole plane 31. For this purpose, the frame members 30 are part of a sub-frame, which is arranged in a portal frame 32 in the direction of the double arrow 33 raised and lowered. The corresponding lowered position is shown schematically in Fig.10.

FIG. 11 schematically shows the height adjustability of the frame members 30 and of the subframe formed by the frame members 30. The height adjustment is again in the direction of the double arrow 33, for which purpose hydraulic cylinder piston units 34 are provided, by means of which the frame beams 30 are mounted in height direction relative to a portal frame 32 adjustable. Furthermore, a pivotable frame part 35 is provided, which can be given away by means of a hydraulic cylinder piston unit 36 in the direction of the double arrow 37 and in this way supports a corresponding lifting of the frame members 30. The crawler undercarriage 12 is in this case fixed to a base frame 38, wherein the relative adjustability of the individual frame to each other in the following Figures 12 and 13 is more apparent.

In Figure 12, the crawler undercarriage is again denoted by 12, wherein the portal frame 32 in addition to a joint 39 with at least two degrees of freedom and laterally each hydraulic Zylinderkolbenaggregate 34 are provided by means of which the frame members 30 having subframe in the height direction relative to the portal frame 32 can be adjusted , In addition, the front guide roller 43 for the conveyor belt is also mounted in a manner not shown between the frame members 30, which in turn is connected in the region of the pivotable frame part via a joint 40 having at least two degrees of freedom to the subframe, so that self-centering of the conveyor belt is made possible. The respective degrees of freedom resulting from the articulation axis of the joints 39 and 40 are shown schematically by the double arrows 41 and 42.

13, the guide roller 43 for the conveyor belt is now shown, wherein the lifting cylinder 34 allow the raising and lowering of the frame members 30 and thus the frame formed by the frame members 30 relative to the frame frame 32. The joint 39, via which the articulated connection of the subframe with the portal frame takes place, hereby allows the schematically illustrated by the double arrows 44 additional freedom of movement.

13, a part of the receiving chute 8 can also be seen in the corresponding partial sectional view. On the frame beams 30, the supporting frameworks shown in FIG. 14 enlarged 29 can be threaded over rollers and stored so that they can be deducted from these frame beams 30 for the extension of the conveyor belt. A guide for the conveyor belt is otherwise visible in Fig.12 with 45.

As shown in FIG. 14, the scaffolds 29 are connected to the ends of the connecting rods 28 via two adjacent locking points 46 in such a manner that tilting of the lateral uprights of the scaffolds 29 is prevented without the need for large floor slabs. The conveyor belt is in this case conveyed via correspondingly arranged support rollers 47, wherein the returning strand of the conveyor belt is supported by the support rollers 48.
