Description

The present invention relates to the field of mechanization of track facilities of railway transport and can be used in the repair (disassembly with subsequent assembly of old and new materials) of the links of the railway track at the production bases of track machine stations.

The well-known "Method for replacing railway sleepers and equipment for replacing railway sleepers", RF patent No. 2072016, MKI E01B 29/06, in which sleepers are removed to the side by a crane from under rails raised by a special device and are similarly replaced with new ones. The disadvantages of the known method for working when repairing rail links at the base include the fact that it requires a normal rail track, which does not exist after cleaning the sleepers, in addition, pulling the sleepers to the side may be impossible due to the train standing nearby, and extremely low productivity (sleepers replacement cycle should not exceed 15-20 seconds). Known: "Device for changing sleepers", and.with. USSR No. 1068570, cl. ЕВВ 29/10; "Device for changing sleepers" A.S. USSR No. 850769, class ЕВВ 29/10 and a number of others created with the aim of replacing sleepers in the current way, which have the same disadvantages, or some of them.

The famous "Trowel", and.with. USSR No. 658204, cl. EB01 29/06. The package of sleepers is fed to the supports by the crane, the bottom row is cut off and fed to the chain conveyor, after which the sleepers are laid out with a trowel on the bench track. The disadvantage of the sleeper is that it cannot be used to stack sleepers selectively, but only in a row, since the conveyor cannot be raised to a height greater than the height of the sleepers. In addition, this trellis is unsuitable for performing sleepers cleaning operations.

A device for arranging reinforced concrete sleepers in a row is known (Link assembly and linking complexes of industrial bases of the ICP: Textbook for universities of railway transport. / Under the editorship of S.G. Shtarev. - M .: Route, 2006. - p. 51 - 53, Fig. 2.7. - taken as a prototype), the basis of which is a spatial portal frame, moving from the drive along the rails of the enclosing path on the wheel supports. Vertical racks of the frame serve as guides for lifting and lowering from the hydraulic cylinders of the platform, on which the gripping levers are rotated in a horizontal plane from the hydraulic cylinders. The levers on which the pile of sleepers is located are lowered using the platform so that the lower row of sleepers lies on the rails of the bench path, after which the levers are parted, raised by the platform on one row, are reduced so that their holder shelves are under the second row of sleepers, and rise with the remaining stack, freeing the bottom row. Then the device moves to the next position and the process repeats. The loading of sleepers onto the device is possible in the same way, provided that the sleepers are shifted on the stand path. The disadvantage of this device is that with its help it is impossible to make a seizure or layout of individual sleepers.

The objective and purpose of the invention is the creation of a mobile device for a single change of reinforced concrete sleepers on the stand when repairing the links of the railway track at the production bases of track machine stations. The objective is achieved in that the mobile device for a single change of reinforced concrete sleepers on the stand during the repair of railway track links, comprising a portal frame moving along the enclosing path of the stand on the drive trolley and supporting a vertically movable platform with pivoting levers for gripping a number of sleepers, is equipped with additional rotary, vertically movable, grippers for one sleepers mounted cantilever in the front of the frame, jumpers are made in the lower part of the frame on which at least two are mounted longitudinal rails to accommodate the step conveyor, in addition, the guide placed Retractable stops.

The step conveyor is made in the form of a carriage movable from the power cylinder, the length of which corresponds to the size of the width of the row of sleepers.

The heated stops are mounted on the rails from the grips for one sleepers, one on each rail so that when the carriage moves to the grippers with the raised sleepers, the sleepers on the carriage cannot move forward.

The heated stops are mounted on rails with a distance from each other in accordance with the width of the sleepers and the number of them on each rail is one less than the number of sleepers in a row, in addition, the stops are installed so that when the carriage returns from grips with a lower sleeper, those remaining in the row the sleepers on the carriage could not move backward.

The implementation of the proposed mobile device with additional rotary, vertically movable grippers for one sleepers, mounted cantilever in the front of the frame, placing jumpers in the lower part of the frame on which at least two longitudinal guides are mounted to accommodate a step conveyor made in the form of a carriage movable from the power cylinder , the length of which corresponds to the size of the width of the row of sleepers, the supply of guides with recessed stops installed on the side of the grippers for one sleepers one at a time on each rail so that when the carriage moves to the grips with the raised sleeper, the sleepers located on the carriage cannot move forward, makes it possible to clean single, defective, sleepers to be replaced from a number of old-fashioned link sleepers that are on the stand path.

The implementation of the proposed mobile device with additional swivel, vertically movable, grippers for one sleepers, mounted cantilever in the front of the frame, placing jumpers in the lower part of the frame on which at least two longitudinal guides are mounted to accommodate the step conveyor, made in the form of movable from the power cylinder carriage, the length of which corresponds to the size of the width of the row of sleepers, the supply of guides with recessed stops installed with a distance from each other in accordance the width of the sleepers and the number of which on each rail is one less than the number of sleepers in a row, set so that during the carriage from the grips with the lowering sleepers, the remaining sleepers on the carriage could not move backwards, ensures the laying of single sleepers instead of the removed, defective sleepers of the link on the bench the way.

The claimed embodiments of a mobile device for a single change of reinforced concrete sleepers on a stand during repair of railway track links at production bases of track machine stations allow the replacement of sleepers not with a crane, but with the help of the claimed device, which reduces the cost of repairing links with reinforced concrete sleepers, increases the degree of mechanization of processes for changing sleepers, eliminates the laborious manual labor of slingers.

A mobile device for a single change of reinforced concrete sleepers on a bench during repair of railway track links includes a drive trolley 1 for moving along the enclosing path 2 of the stand 3. A portal frame 4 is supported on the trolley 1, vertical racks 5 of which serve as guides for the sliders 6 of the platform 7. Vertical movement of the platform 7 is carried out by hydraulic cylinders 8. On the platform 7, L-shaped levers 9 are pivotally mounted with a drive from hydraulic cylinders 10 to capture a number of sleepers. On the lower part of the frame 4, jumpers 11 are made on which at least two longitudinal guides 12 are mounted to move a step conveyor that performs reciprocating movements and is made, for example, in the form of a carriage 13 driven by a hydraulic cylinder 14. The length of the carriage 13 corresponds to the size of the row width sleepers. On the front uprights 5 of the portal frame 4, in the cantilever-mounted guides 15, a beam 16 is installed on which the grippers 17 for one sleepers are placed with the possibility of rotation around the horizontal axis from the hydraulic cylinders 18 and vertical movement from the hydraulic cylinders 19. The magnitude of the stroke of the grippers 17 for one sleepers during vertical movement must be at least the distance from the rail head of the bench path 3 to the top of the carriage 13. On the rails 12 are installed recessed stops 20.

To clean individual, defective, old-fashioned reinforced concrete sleepers of links on the bench path 3 in a mobile device, it is enough to install one stop 20 at the end of each rail 12 from the gripper side 17 for one sleeper, so that sleepers already immersed on the carriage 13, during the course of the carriage 13 to the grippers 17 with the sleepers raised from the bench 3, they could not move forward.

To lay individual reinforced concrete sleepers (instead of cleaned, defective, old sleepers) links on the bench 3 in the mobile device, the number of stops 20 on each rail 12 should be one less than the number of sleepers in a row with the distance between the stops 20 corresponding to the width of the sleepers. The stops 20 are installed in such a way that the sleepers remaining on the carriage 13 during the carriage 13 from the grippers 17 with the sleeper lowered onto the bench path 3 cannot move back.

A mobile device for a single change of reinforced concrete sleepers on a stand during the repair of links of the railway track works as follows.

Old-fashioned rail links with reinforced concrete sleepers, intended for repair, are laid out on the stand path 3. After work on unscrewing the nuts and cleaning the rails, old-fashioned reinforced concrete sleepers remain on stand track 3, some of which must be replaced. The mobile device, designed to clean the defective sleepers from a number of old sleepers one at a time, moves along the enclosing path 2 of the bench path 3 and stops so that grips 17 for one sleeper are located above the replaced sleeper. The grips 17 of the hydraulic cylinders 18 are rotated around the horizontal axis and are bred to a size corresponding to the length of the sleepers, and with the help of the hydraulic cylinder 19 the sleepers are lowered slightly below the bed (Fig. 3, position a), are reduced by the hydraulic cylinders 18 and raised by the hydraulic cylinders 19 together with the sleepers a little higher carriage 13. The carriage 13 with the hydraulic cylinder 14 is brought under the raised sleepers, which in the grippers 17 is lowered by the hydraulic cylinders 19 onto the carriage 13 (Fig. 3, position b). The grippers 17 are parted, the sleeper is released, and the carriage 13 is diverted by the hydraulic cylinder 14 from under the grippers 17 (Fig. 3, position c). The mobile device moves to the next sleeper to be replaced. The rise of each next to be replaced sleepers and placing them on the carriage 13 is carried out similarly to the first. In this case, the previous sleeper runs into the recessed stop 20, it is recessed, the sleeper slides along the carriage 13. Having passed the sleeper, the recessed stop 20 under the action of a spring (not shown) takes its initial position until it meets the next sleeper. The sleepers located on the carriage 13 (raised and laid by the grippers 17), when the carriage 13 moves to the grippers 17 with the next sleeper raised from the bench 3, rests against the stop 20 and cannot move forward. After the first full row of sleepers is gathered on the carriage 13, the platform 7 is lowered by the hydraulic cylinders 8, the L-shaped levers 9 are turned by the hydraulic cylinders 10 and bred to a size corresponding to the length of the sleepers. The platform 7 falls even lower, the levers 9 are shifted, capturing the dialed row of sleepers, and the platform 7 is lifted by hydraulic cylinders 8, freeing up space for the next row of sleepers. After the second (and subsequent rows) full row of sleepers is typed on the carriage 13, wooden gaskets are laid on it, the platform 7 is lowered by the hydraulic cylinders 8, laying on the assembled row the previous rows of sleepers, the L-shaped levers 9 are rotated by the hydraulic cylinders 10 and scaled apart, corresponding to the length of the sleepers. The platform 7 falls even lower, the levers 9 are shifted, capturing the dialed row of sleepers, and the platform 7 is lifted by hydraulic cylinders 8, freeing up space for the next row of sleepers. Unloading the set of sleepers is done by crane.

Following the mobile device for cleaning individual reinforced concrete sleepers, a mobile device moves, designed to stack new sleepers instead of the removed ones. The package of sleepers is loaded by a crane with the levers 9 apart and mounted on the carriage 13. The platform 7 is lifted by the hydraulic cylinders 8 so that the second row of sleepers can be gripped by the levers 9. The platform 7 is raised by hydraulic cylinders 8, the lower row of sleepers remains on the carriage 13. Between the sleepers there are recessed stops 20. The number of recessed stops 20 on each rail 12 is one less than the number of sleepers in a row. Wooden linings (not shown in the drawing) are removed from the row of sleepers that remained on the carriage 13 and the whole row is moved by the carriage 13 with the help of hydraulic cylinders 14 so that the front sleeper is under the jaws 17, which are in the initial (extended) position (Fig. 5, position d). Captures 17 are reduced by hydraulic cylinders 18, capture the sleeper, and after the carriage 13 is retracted, lower it onto the bench path 3 instead of the removed one (Fig. 5, position e). The grips 17 are opened by the hydraulic cylinders 18, free the sleeper and rise to the initial position by the hydraulic cylinders 19. When the carriage 13 is retracted to the initial position, the sleepers remaining on the carriage 13 rest against the stop 20 and cannot move back. The next sleeper, which was the second in a row, runs into the stop 20, drowns it, slides along the carriage 13 and is under the grab 17. Each of the next sleepers is replaced similarly to the first. When the first row of sleepers is laid out instead of the cleaned ones, the platform 7 with the package of sleepers is lowered and the package of sleepers is installed on the carriage 13. Then everything is repeated, as with the first row.
