Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1 to 6A tooling for disassembling and assembling a coupler buffer device for subway vehicles includes a moving car 10, a lifting plate 2, three support plates 3 of different heights, and a driving device. The driving device is mounted on the moving car 10 to drive the lifting plate 2 to move up and down. The three support plates 3 are spaced apart on the lifting plate 2, and two of the support plates 3 have through slots. The tooling also includes:

[0023] Two L-shaped plates 4 are slidably connected to the slot at their bottoms, and two sliding grooves 401 are provided on the L-shaped plates 4 at intervals;

[0024] Four T-shaped side plates 5, one end of which can slide within the groove 401;

[0025] Two first fixing devices are used to fix the L-shaped plate 4 on the support plate 3;

[0026] Two second fixing devices are used to fix the two T-shaped side plates 5 onto the L-shaped plate 4. In this utility model, during use, after the subway car to be inspected is lifted and raised using specialized equipment, the lifting plate 2 is moved to the bottom of the coupler buffer device by the mobile vehicle 10. The drive device drives the lifting plate 2 to move upward until the three support plates 3 respectively contact the bottom of the coupler buffer device. After the coupler buffer device is removed from the subway car, the drive device drives the lifting plate 2 to move downward back to its original position, inserts the L-shaped plate 4 into the slot, and fixes it with the first fixing device. Then, the two T-shaped side plates 5 are installed on the L-shaped plate 4 and fixed with the second fixing device to prevent the coupler buffer device from falling off the lifting plate 2 when the mobile vehicle 10 moves to the inspection site. Specifically, the drive device includes an electro-hydraulic rod 11.

[0027] As a preferred embodiment of this utility model, it may also have the following additional technical features:

[0028] In this embodiment, the bottom of the mobile vehicle 10 is provided with a U-shaped plate 101, and the bottom of the drive device passes through the mobile vehicle 10 and is connected to the U-shaped plate 101, thereby reducing the distance between the lifting plate 2 and the ground and facilitating the removal of the coupler buffer device from the lifting plate 2.

[0029] In this embodiment, the mobile vehicle 10 is provided with a cavity 102, which can hold tools for disassembly and assembly.

[0030] In this embodiment, the L-shaped plate 4 is provided with a threaded hole 402; the first fixing device includes an outer tube 6 and an inner rod 7. The inner rod 7 is disposed on one of the support plates 3. The outer tube 6 is threadedly connected to the inner rod 7. The outer tube 6 can be screwed into the threaded hole 402. After the L-shaped plate 4 is inserted into the slot, one side of the L-shaped plate 4 contacts the side of the coupler buffer device. The outer tube 6 is rotated to cooperate with the threaded hole 402, thereby fixing the L-shaped plate 4 on the support plate 3.

[0031] In this embodiment, the second fixing device includes a T-shaped limiting rod 8 and a screw 9. The limiting rod 8 is screwed to the T-shaped side plate 5, and the screw 9 is screwed to the L-shaped plate 4. After the L-shaped plate 4 is installed, the T-shaped side plate 5 is inserted into the slide groove 401, with one side contacting the coupler buffer device. The limiting rod 8 is rotated to make it vertical, and the screw 9 is rotated so that one end contacts one end of the T-shaped side plate 5, thereby fixing it.
