Description

Description

The utility model relates to a cleaning machine with signs of a restrictive part of claim 1 of the formula.

A similar cleaning machine is already known from DE 4343148 Al, FR 1029167 and DD 240043 Al. This machine consists of a frame moving along the railway track / between the end rail running gears of which two extraction chains are located directly one after the other. A screening unit is located between the two extraction chains. While during continuous advancement of the machine with the front, the first extraction chain, the crushed stone is fed to the screening unit, removal is carried out using the second extraction chain

soil, which serves as the basis of crushed stone ballast. It is dumped by a conveyor, for example, into a subsequent storage car. Before dumping the cleaned gravel, sand is laid to make a protective layer of the subgrade.

From FR 714645, the arrangement of four endless scoop chains is known, with which crushed stone is transported upward and fed to a screening plant.

Another base sanitation machine is known from EP 0 629 744 B1. The layer of crushed stone removed by the first extraction chain is crushed in a stone crusher, dumped to make a protective layer of the subgrade on the way, and compacted. With the help of the second extraction chain located on the second frame of the machine, soil is excavated, which is replaced by a protective layer of the subgrade. After this, the path is laid. During another operation, new crushed stone is laid for the production of crushed stone ballast.

The objective of this utility model is to create a generic machine, with which, using two extraction chains, it would be possible to achieve a particularly high cleaning performance.

According to the utility model, this problem is solved by means of a cleaning machine of the kind described above with the characteristics given in the characterizing part of claim 1 of the formula.

For the first time, a machine with these features provides, when using two extraction chains located one after another, a significant increase in productivity with respect to grabbing gravel, so that up to the limit of productivity

even very large screening plants can be loaded. Due to the location of two extraction chains on one common frame of the machine, in combination with a correspondingly large reconstruction gap achieved by the moving rail running mechanism, it is possible, despite a special increase in productivity, to reduce structural costs compared to using two machines.

Other advantages and performance of the utility model are given in the dependent claims and in the drawing.

The utility model is described in more detail below using the example execution shown in the drawing, which represent:

- figures 1 and 2; side view of the front and rear relative to the working direction of the parts of the cleaning machine;

- figure 3: schematic top view of a variant of the extraction chain. Shown in figures 1 and 2, the cleaning machine 1 for cleaning ballast ballast 2 of the path 3 contains a frame 5 moving on the rail running gears 4. The latter is connected to two excavation chains 7, 8 mounted between the end rail running gears 4 with the possibility of moving vertically and horizontally by means of drives 6. These extraction chains 7, 8 located one after the other in the longitudinal direction of the machine are each endless with the possibility of being driven into rotation for excavation of crushed stone 10 by drive 9. Above each internal circuit 7, 8 is working cabin 11 with control device 12 for monitoring is under segment 3 by a chain.

To lift the path 3 with the frame 5 of the machine with the possibility of moving vertically and horizontally by means of the drives 13, two overhead lifting devices are connected 14. The rail gear 4, front relative to the working direction (arrow 15) of the cleaning machine 1, is installed in the guide 16 of the frame 5 of the machine for moving regarding her.

The frame 5 of the machine is composed of the first part 17 located in front of the working direction and connected to it by a hinge 18 of the second part 19. Both frame parts 17, 19 are arranged to move along the path 3 by means of a rail running gear 4 connected to the second frame part 19 in the zone hinge 18.

To remove crushed stone 10, the first extraction chain 7 is provided with a conveyor 20 with a receiving end 21 and a discharge end 22. The latter is located above the screening unit 23 located on the driveway 24 for screening connected to the frame 5 of the machine ********. To remove ************* with a chain 8 of the remaining crushed stone 10, a second conveyor 25 is provided with a receiving 26 and dropping 27 ends.

Finally, a third conveyor 28 extending in the longitudinal direction of the machine, with a place 29 for throwing crushed stone positioned between the second extraction chain 8 and the subsequent rail running mechanism 4. Finally, a conveyor 28 is located above the excavation chain 7 and runs in the middle through the second extraction chain 3 to the crushed stone dumping site 29 located directly above the path 3.

Between both end rail rails 4 of the second part 19 of the frame, a brush 31 rotatable by the drive 30 and a belt conveyor 32 are provided for filling the frontal hopper 33 for crushed stone. The power unit 34 serves to power the travel drives 35 and various other drives.

Immediately before starting work, the front rail mechanism 4 of the first part 17 of the frame is moved from the retracted position indicated by dash-dot lines (Fig. 1) to the working position indicated by solid lines. Thus, the reconstruction period is increased, limited by the movable rail running gear 4 and the next rail running gear 4, and for both extraction chains 7, 8, joint lifting of the path 3 is simplified.

During operation, while continuously moving the machine 1 in the first stage, the upper layer of ballast gravel 2 is removed by the first extraction chain 7. The ballast 10 taken by it is fed for cleaning along the first conveyor 20 to the screening unit 23 located in front. Located in the first working cabin 11. the operator can, using the control device 12, if necessary, control the first extraction chain 7 lying directly in front of it.

With the elevated path-lifting device 14 of the path 3 immediately behind the first extraction chain 7, the second crushed stone layer is removed in parallel with the second extraction chain 8, transported to the second conveyor 25 and fed from it to the second screening unit 23 for cleaning. The operator located in the second work booth 11 can also

the control device 12, if necessary, to control the second extraction chain 8 lying directly below it.

Taken by both extraction chains 7.8 and cleaned in the screening unit 23, the crushed stone 10 is transported using the third conveyor 28 to the crushed stone dumping place 29 located behind the second extraction chain 8 and dumped onto the raised path 3 for re-production of crushed stone ballast 2.

With the help of a subsequent brush 31, it is possible to brush away the rubble lying on the sleepers and, possibly, in some places too much crushed stone 10 can be transported via the belt conveyor 32 to the crushed stone hopper 33.

Preferably, one of the two extraction chains 7, 8 can be made visible in figure 3 and known from US 4614238. This recess chain 8, which is equipped with hinges 36 and a displacement drive 37, has the advantage that, when loading the displacement drive 37, an instantaneous and smooth change in the width of the recess is possible. Thus, the machine 1 can also be used in switch sections, and the front, normally made dredging chain 7 remains inoperative.
