Rack for maintenance and current repair of motor-car rolling stock

 

The invention relates to equipment for maintenance and repair of motor-car rolling stock and is designed for positioning of the cars. Rack for maintenance and repair of motor-car rolling stock contains track 1 on the supporting pillars, travel breakaway bridges, pull-out support, transport and lifting mechanism and the device for moving rolling stock. Device for moving rolling stock placed in the pit rail and consists of a frame 10, a pumping station 11 and the guide beams 12 with shelter. In the parallel grooves of the beam 12 mounted carriage 13, pivotally connected with one side of the power cylinder 14, the pusher 15, equipped with a hitch. Directing a beam connected to the frame with two parallel arms 17 can move in the vertical plane through the cylinder 18 of the lift. The invention provides precise mounting of bogies rolling stock on disconnecting the bridge. 9 Il.

The invention relates to the equipment rack for maintenance and current repair of motor-car rolling stock which I tensile forces in the coupling device in any car-to-car coupling.

Famous bridge maintenance and replacement trucks (New depot city rail Hanover, - Railways of the world - 2001. - 1. - S. 39-43). Before replacing trucks train posted via mobile special lifts that are installed under the special points of the body. Dolly under the train rolls out with transport trucks and delivered to the shop maintenance. The disadvantage of this technical solution is that to replace the trucks need to carry out simultaneous rise of the trains.

The closest technical solution of the present invention is a rack for replacement trucks (Hakobyan, A. Locomotive depot of the new generation, Railway transport, - 2000. - 1. - S. 49-55). The rack is equipped with automatic disconnecting and walkways located under each trolley rolling stock, retractable legs for supporting the body and transport and lifting mechanism, which is put under any directional breakaway bridge pickup truck. The disadvantage of this technical solution is that all the trucks rolling stock cannot be simultaneously installed with the required accuracy on the travel breakaway mos and location travel breakaway bridges, as well as inaccurate stop rolling stock engineer.

The invention solves the problem of providing accurate installation every truck rolling on the path disconnecting the bridge.

To achieve the technical result, the rack is equipped with a device for moving rolling stock. The device is placed in the pit rail and consists of a frame, a pumping station and directing a beam with shelter, parallel grooves which includes the carriage, pivotally connected on one side with a hydraulic power cylinder, the pusher is equipped hitch, while directing a beam connected to the frame by two parallel levers that can move in a vertical plane by means of the lift cylinder.

The inventive rack is illustrated by the drawings shown in figures 1, 2, 3, 4, 5, 6, 7, 8 and 9: Fig.1 shows a rack with rolling stock and a device for moving rolling stock; Fig.2 - callout a in Fig.1; Fig.3 shows a device for moving rolling stock in the working position (General view); Fig.4 - view of B in Fig.3; Fig.5 - external element In Fig.3; Fig.6 - section G-G in Fig.7.

in Fig.9 is a view E of Fig.7; Rack, consisting of the track 1, the supporting struts 2, track breakaway bridges 3, outrigger base 4 and the transport and lifting mechanism 5 for replacement trucks 6 rolling stock 7, equipped with a device 8 for moving the rolling stock 7, which is placed in the pit 9 track 1. The device 8 consists of a frame 10, a pumping station 11, is rigidly fixed in pit 9, and the guide beams 12. In the guide beam 12 is parallel grooves "and" have the carriage 13 can move in these grooves by means of a cylinder 14 mounted on the guide beam 12 and pivotally connected to the carriage 13. On the carriage 13 is fixed to the plunger 15, which is equipped with a coupling device 16 for connection with the drawbar of the rolling stock 7. The guide beam 12 is connected to the frame 10 by two parallel arms 17 can move in the vertical plane, for installation in the upper working position by means of the lift cylinder 18 connected to the frame 10 and one of the levers 17. At the top, above the guide bar 12, a cover 19 made in the form of a metal frame, fixed by means of brackets 20 to reesei platform closing the pit 9 at the level of the top of the head rail 1, for the passage of mobile equipment rack when the device 8 in the lower off position.

The positioning of the trolley 6 is produced as follows. The guide beam 12 is installed in the upper working position of the lift cylinder 18, which is driven pump station 11. Then hydraulic power cylinder 14 moves the carriage 13 with the plunger 15 to the connection of the coupling device 16 with the drawbar of the rolling stock 7 mounted on the rack, the carriage 13 is moved in the parallel grooves "and" guide beams 12. With one of the stations, located near remanufactured truck 6, the driving force of the hydraulic cylinder 14, to produce the positioning of the trolley 6, set her on the path disconnecting the bridge 3, combining the transverse plane "b" carriage 6 with the cross-plane "in the" path disconnecting the bridge 3, thereby allowing removal and replacement of truck 6. To control the coupling device of the rolling stock 7 in any inter-coupling hydraulic power cylinder 14 create tensile stress inhibited when the last car rolling stock 7 device 8. The transfer device is reesei platform for mobile equipment racks.

The application of the proposed device for moving rolling stock will allow you to:
- to provide the movement of rolling stock for accurate setting of any truck on the road disconnecting the bridge for its removal and replacement;
- reduce the complexity and to reduce the time to work on the replacement of trucks rolling stock, thus reducing the time for its maintenance;
to ensure unimpeded through the passage of rolling stock and mobile equipment racks;
to create tensile stress in any inter-coupling of the rolling stock to control coupling devices and their replacement.
