Detailed Implementation

[0023] 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.

[0024] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a special tooling for the maintenance of end equipment of subway vehicles, including a base plate 100, a subway vehicle track 101 and an auxiliary track 102 are arranged above the base plate 100; a movable carriage 200 is movably installed on the auxiliary track 102, a lifting and moving structure is connected above the movable carriage 200, a guide frame 300 and a U-shaped guard plate 400 are connected to the lifting structure, a lifting and conveying structure is connected to the guide frame 300, and a protective structure is connected to the U-shaped guard plate 400.

[0025] Furthermore, the lifting and moving structure includes two U-shaped frames 201, both of which are installed above the moving slide 200. The same support platform 202 is slidably mounted on the two U-shaped frames 201. Two winding rollers 203 are rotatably mounted between the two U-shaped frames 201. A connecting rope 204 is wound around each of the two winding rollers 203. A reduction motor 205 is installed at one end of each of the two connecting ropes 204. The two reduction motors 205 are respectively installed on both sides of the support platform 202. By turning on the reduction motors 205 on both sides, the winding rollers 203 can be driven to rotate. The rotating winding rollers 203 can wind up the connecting ropes 204, pulling the lifting slide 206 to move upward. The rising lifting slide 206 will drive the support platform 202 to rise. By controlling the winding and unwinding of the connecting ropes 204, the height of the support platform 202 can be adjusted so that the staff can be brought to the corresponding height and position to inspect the end of the subway car.

[0026] Furthermore, the U-shaped frame 201 has a vertical slide groove 207 inside, and a vertical slide bar 208 is slidably installed in the vertical slide groove 207. The vertical slide bar 208 is installed on one side of the lifting slide 206. When the lifting slide 206 rises, it can drive the vertical slide bar 208 to slide in the vertical slide groove 207. The setting of the vertical slide groove 207 and the vertical slide bar 208 can limit the movement direction of the lifting slide 206 and prevent its position from shifting.

[0027] Furthermore, several pulleys 209 are rotatably mounted inside the movable carriage 200. The pulleys 209 are in contact with the surface of the auxiliary track 102. A drive motor 210 is mounted on one side of the movable carriage 200. The output end of the drive motor 210 passes through the movable carriage 200 and is mounted on the corresponding pulley 209. When the drive motor 210 is turned on, it can drive the corresponding pulley 209 to rotate. When the pulley 209 rotates, it will roll on the auxiliary track 102 and drive the movable carriage 200 to move.

[0028] Example 2: As Figure 1-5 To facilitate the transport of tools and repair parts to the workers above, a lifting and transporting structure is provided. This structure includes a lead screw 301, which is rotatably mounted inside a guide frame 300. The guide frame 300 is mounted on one side of the support platform 202. An L-shaped connecting plate 302 is threaded onto the lead screw 301. A toolbox 303 is mounted on one side of the L-shaped connecting plate 302. An auxiliary motor 304 is mounted above the guide frame 300, with its output end mounted on the lead screw 301. Activating the auxiliary motor 304 rotates the lead screw 301, causing it to move vertically. This allows the L-shaped connecting plate 302 to lift and lower the toolbox 303. During repair work, the toolbox 303 can be lowered to the ground, allowing other workers to place repair tools or replacement parts inside and then lift the toolbox 303 to deliver it to the workers. The remaining features are the same as in Embodiment 1.

[0029] Example 3: As Figure 2-3 To catch accidentally dropped maintenance tools within a certain range, a protective structure is installed. This structure includes two mounting strips 401, which are respectively installed below the U-shaped guard plate 400 and the support platform 202. A protective net 402 is installed between the two mounting strips 401. Two fixed seats 403 are installed on the support platform 202, and a guide rod 404 is installed between the two fixed seats 403. A limiting slide 405 is slidably mounted on the guide rod 404. The limiting slide 405 is installed on one side of the U-shaped guard plate 400. The internal thread of the sliding block 405 is fitted with a screw 406, which presses against the surface of the guide rod 404. If the tool is accidentally dropped during maintenance, the U-shaped guard plate 400 and the guard net 402 below can catch the falling tool within a certain range. Rotating the screw 406 can release the position restriction on the sliding block 405. Pushing the sliding block 405 can move the U-shaped guard plate 400 and stretch the guard net 402, changing the catching range of the guard net 402. The remaining features are the same as in Embodiment 1.

[0030] The working principle is as follows: The subway car travels along the subway car track 101 to the front of the support platform 202, that is, the side of the support platform 202 away from the toolbox 303. Then, the staff can enter the support platform 202. By turning on the drive motor 210, the corresponding pulley 209 can be rotated. When the pulley 209 rotates, it will roll on the auxiliary track 102 and drive the movable slide 200 to move, which in turn drives the U-shaped frame 201 and the lifting slide 206 to move. This causes the lifting slide 206 to move the support platform 202 closer to the end of the subway car. Then, by turning on the reduction motors 205 on both sides, the winding roller 203 can be rotated. The rotating winding roller 203 can wind up the connecting rope 204, causing one end of the connecting rope 204 to pull the lifting slide 206 upward. The rising lifting slide 206 will then move along the support platform 202. The support platform 202 rises, and its height can be adjusted by controlling the release and retraction of the connecting rope 204, so that workers can be brought to the corresponding height and position to inspect the end of the subway car. By activating the auxiliary motor 304, the lead screw 301 can be rotated. The rotating lead screw 301 can drive the L-shaped connecting plate 302 to move vertically within the guide frame 300 through the threaded engagement with the L-shaped connecting plate 302. This allows the L-shaped connecting plate 302 to drive the toolbox 303 to move up and down. During the inspection process, the toolbox 303 can be lowered to the ground, and then other workers can place the inspection tools in the toolbox 303 and transport them to the inspection workers by controlling the toolbox 303 to rise. Alternatively, parts disassembled during the inspection can be transported down through the toolbox 303.

[0031] If a worker accidentally drops a tool during maintenance, the U-shaped guard plate 400 and the protective net 402 installed below can catch the falling tool within a certain range, reducing the probability of the tool falling to the ground. Rotating the screw 406 allows it to move through its threaded engagement with the limiting slide 405, causing the moving screw 406 to release its pressure on the guide rod 404. This releases the positional restriction on the limiting slide 405, allowing it to slide on the guide rod 404 and move the U-shaped guard plate 400. The U-shaped guard plate 400 then stretches the protective net 402 through the mounting strip 401. The protective net 402 can be made of elastic material to accommodate the movement and adjustment of the U-shaped guard plate 400, allowing the position of the U-shaped guard plate 400 to be adjusted according to the spacing at the ends of the subway car, while also changing the catching range of the protective net 402.
