Description

 The invention relates to equipment of a flyover for maintenance and repair of a motor-car rolling stock and is intended for positioning any carriage of a rolling stock on a separation bridge and creating tensile force in the coupling devices in any inter-car coupling.

 Known overpass for maintenance and replacement of carts (New depot of the city railway of Hanover, - Railways of the world, - 2001. - 1. - P.39-43). Before changing the trolleys, the electric train is hung out using special mobile lifts installed under special points on the body. The trolley from under the train is rolled out using a transport trolley and delivered to the maintenance workshop. The disadvantage of this technical solution is that to replace the trolleys, it is necessary to carry out a synchronous lift of the electric train.

 The closest technical solution to the proposed invention is the overpass for the replacement of carts (Hakobyan GA Locomotive depot of a new generation, - Railway transport, - 2000. - 1. - P.49-55). The overpass is equipped with track disconnecting bridges located under each rolling stock carriage, sliding supports for supporting the body and a transport and lifting mechanism, which is wound under any track disconnecting bridge to remove the trolley. The disadvantage of this technical solution is that all the bogies of the rolling stock cannot be simultaneously installed with the required accuracy on the track disconnecting bridges.

 The inaccuracy of the installation is due to the unfavorable combination of tolerances on the length of the rolling stock and the location of the track disconnecting bridges, as well as the inaccurate stopping of the rolling stock by the driver.

 The present invention solves the problem of ensuring the accurate installation of any carriage rolling stock on the track disconnect bridge.

 To achieve the specified technical result, the overpass is equipped with a device for moving rolling stock. The device is located in the pit of the rail track and consists of a frame, a pumping station and a guide beam with a shelter, in parallel grooves of which a carriage is mounted pivotally connected on one side to the power hydraulic cylinder, and on the other to a pusher equipped with a coupling device, while the guide beam is connected with a frame with two parallel levers with the possibility of its movement in a vertical plane by means of a lifting hydraulic cylinder.

The inventive flyover is illustrated by the drawings shown in figures 1, 2, 3, 4, 5, 6, 7, 8 and 9:

An overpass, consisting of a rail track 1, support racks 2, track disconnect bridges 3, slide supports 4 and a transport and lifting mechanism 5 for replacing the trucks 6 of the rolling stock 7, is equipped with a device 8 for moving the rolling stock 7, which is located in the pit 9 of the rail track 1. The device 8 consists of a frame 10, a pumping station 11, rigidly fixed in the pit 9, and a guide beam 12. In the guide beam 12 are parallel grooves "a", in which the carriage 13 is mounted with the possibility of movement in these grooves by means of forces of the hydraulic cylinder 14 mounted on the guide beam 12 and pivotally connected to the carriage 13. A pusher 15 is mounted on the carriage 13, which is equipped with a coupling device 16 for connecting to the coupling device of the rolling stock 7. The guide beam 12 is connected to the frame 10 by two parallel levers 17 with the possibility of its movement in a vertical plane, for installation in the upper working position by means of a lifting cylinder 18, connected to the frame 10 and one of the levers 17. Above, above the guide beam 12, a shelter 19 is installed, in made in the form of a metal frame fixed with brackets 20 to the guide beam 12, which is designed to protect the device from mechanical damage and serves as a crossing platform covering the pit 9 at the level of the top of the rail tracks 1, for passing overpass mobile equipment when the device 8 is in lower idle position.

 The positioning of the carts 6 is as follows. The guide beam 12 is installed in the upper working position by the lifting cylinder 18 driven by the pump station 11. Then, the power cylinder 14 moves the carriage 13 with the pusher 15 until the coupling device 16 is connected to the coupling device of the rolling stock 7 mounted on the overpass, while the carriage 13 is moved in parallel grooves "a" of the guide beam 12. From one of the stationary posts located near the replaced trolley 6, controlling the power hydraulic cylinder 14, the positioning of the trolley 6 is made, installed pour it on the track disconnect bridge 3, combining the transverse plane "b" of the cart 6 with the transverse plane "in" the path disconnect bridge 3, thereby providing removal and replacement of the cart 6. To control the coupling devices of the rolling stock 7 in any inter-car coupling with the power hydraulic cylinder 14 create a tensile force when the last rolling carriage 7 is braked from the device 8. The device 8 is transferred to the lower idle position in the reverse order, while the shelter 19 is used as a crossing schadki mobile equipment racks.

The use of the proposed device for moving rolling stock will allow:
- to ensure the movement of rolling stock for the precise installation of any of its carts on the track disconnecting bridge for its removal and replacement;
- to reduce the complexity and reduce the time for work on the replacement of rolling stock trolleys, thereby reducing the time for its maintenance;
- to provide unobstructed through passage of rolling stock and mobile equipment of an overpass;
- to create a tensile force in any inter-vehicle coupling of the rolling stock to control the coupling devices and replace them.
