The bottom end of each hydraulic cylinder 202 is fixedly connected to the bottom plate of the receiving groove 102. A cleaning device 3 is provided on one side of the two maintenance platforms 2 close to the track 101 for cleaning both sides of the vehicle. The cleaning device 3 includes a cleaning groove 301 opened on the maintenance platform 2. A moving groove 303 is opened on one side of the cleaning groove 301. The moving groove 303 is perpendicular to and communicates with the cleaning groove 301. The depth of the cleaning groove 301 is the same as the depth of the moving groove 303. A cleaning plate 302, a driving component 5 and a pushing component 4 are sequentially provided in the cleaning groove 301. The execution end of the driving component 5 is located in the moving groove 303. The pushing component 4 includes electric telescopic rods 401 symmetrically arranged inside the cleaning groove 301. Both electric telescopic rods 401 are fixedly connected to the inner wall of the cleaning groove 301, and the telescopic ends of both electric telescopic rods 401 are fixedly connected with fixing plates 402. Electromagnets 403 are embedded on the side of the two fixing plates 402 close to the cleaning plate 302. Both electromagnets 403 are magnetically adsorbed to the upper and lower ends of the back of the cleaning plate 302. The driving component 5 includes a moving block 505 fixedly connected to the center of the back of the cleaning plate 302. The moving block 505 is sleeved on a lead screw 504. One end of the lead screw 504 is connected to the inner side wall of the cleaning groove 301 through a movable block 506. The other end of the lead screw 504 is located in the moving groove 303. A driving cavity 501 is opened on one side of the maintenance platform 2 inside the moving groove 303. A driving motor 502 is provided inside the driving cavity 501. The driving motor 502 is connected to the driving cavity 501 through a mounting plate 503, and the output end of the driving motor 502 is fixedly connected to the lead screw 504 through a coupling. A second sliding groove 3011 is opened on the inner side wall of the cleaning groove 301. The movable block 506 is located in the second sliding groove 3011.

[0031] After the vehicle enters the maintenance channel 1 through the track 101, the staff can stand on the maintenance platform 2 in advance. The operator starts the hydraulic cylinder 202, and the work of the hydraulic cylinder 202 can raise the maintenance platform 2, facilitating the staff to reach the top of the vehicle for equipment maintenance. Or after the maintenance platform 2 rises, the staff climbs to the top of the platform through the ladder 204. After the maintenance platform 2 stops rising, the pushing component 4 in the cleaning device 3 is started. The work of the pushing component 4 pushes the cleaning plate 302 out of the cleaning groove 301, and the moving cleaning groove 301 drives the driving component 5 to move. Then the driving component 5 works to make the cleaning plate 302 move horizontally along the moving groove 303 to clean the outer wall of the vehicle. Thus, through the receiving groove 102 and the hydraulic cylinder 202, the maintenance platform 2 can be hidden in the maintenance channel 1 to avoid occupying space, and the storage and deployment are simple and fast. At the same time, the deployed maintenance platform 2 can clean the outer wall of the vehicle;

[0032] Further, the electric telescopic rod 401 in the pushing component 4 works, and its telescopic end drives the fixed plate 402 to move. The fixed plate 402 pushes the cleaning plate 302 out of the cleaning groove 301. When the cleaning plate 302 is pushed, it drives the moving block 505 in the driving component 5 to move. The moving block 505 drives the movable block 506 and the mounting plate 503 for fixing the driving motor 502 to move through the lead screw 504 respectively. The movable block 506 moves along the second chute 3011 through the sliding chute 3012 and the sliding block 5061. The mounting plate 503 moves in the driving cavity 501 along the slide rail 5011 through the first chute 5031, facilitating the cleaning plate 502 to move out of the cleaning groove 301. Among them, the electromagnet 403 is in a power-off state. When the cleaning plate 302 is received, the electromagnet 403 is energized to generate magnetism to adsorb the cleaning plate 302. At this time, the electric telescopic rod 401 contracts, and its telescopic end drives the cleaning plate 302 and the driving component 5 to reset;

[0033] Further, the driving motor 502 in the driving component 5 works, and the driving motor 502 drives the lead screw 504 to rotate. The rotating lead screw 504 makes the moving block 505 move along the groove wall under the restriction of the moving groove 303. The moving block 505 drives the cleaning plate 302 to move, and the moving cleaning plate 302 cleans the outer wall of the vehicle.

[0034] Please refer to FIGS. 3 and 4. On one side of the two cleaning plates 302 close to the track 101, a number of spray nozzles 3021 are vertically provided. On one side of the number of spray nozzles 3021, there is a cleaning sponge 3022. The two cleaning sponges 3022 are adhesively fixed to the cleaning plates 302. At the top of the back of the two cleaning plates 302 away from the spray nozzles 3021, there are telescopic hoses 602 connected. The two telescopic hoses 602 communicate with the cavities opened inside the cleaning plates 302. Inside the maintenance platform 2, on one side of the two storage grooves 102, there are water tanks 6. In both of the two water tanks 6, there are water pumps 601 installed. The other ends of the two telescopic hoses 602 pass through the maintenance platform 2 and the water tanks 6 in sequence and are connected to the output ports of the water pumps 601. On the upper surface of the maintenance channel 1 at the positions of the two water tanks 6, there are water filling ports 603 communicated with them. Removably installed on the two water filling ports 603 are sealing covers flush with the upper surface of the maintenance channel 1.

[0035] When the cleaning plates 302 move, start the water pump 601. The working water pump 601 sends the water in the water tank 6 into the cleaning plates 302 through the telescopic hoses 602 and sprays it from the spray nozzles 3021 onto the outer wall of the vehicle. At this time, the cleaning sponges 3022 are in contact with the outer wall of the vehicle. When the cleaning plates 302 move, they drive the spray nozzles 3021 and the cleaning sponges 3022 that are spraying water to move. The spray nozzles 3021 spray and wash the outer wall of the vehicle, and the cleaning sponges 3022 wipe the outer wall of the vehicle after spray washing, so as to clean the outer wall of the vehicle.

[0036] Workflow of the present invention: After the vehicle enters the maintenance channel 1 through the track 101, the hydraulic cylinder 202 can work to raise the maintenance platform 2. The staff can stand on the maintenance platform 2 in advance or climb up through the ladder 204, which is convenient for reaching the top of the vehicle to complete the maintenance of the equipment. At the same time, the pushing component 4 and the driving component 5 in the cleaning device 3 are started in sequence. The electric telescopic rod 401 in the pushing component 4 works, and its telescopic end drives the fixed plate 402 to move. The fixed plate 402 pushes the cleaning plate 302 out of the cleaning groove 301 to move, so that the cleaning sponge 3022 contacts the outer wall of the vehicle. When the cleaning plate 302 is pushed, it drives the moving block 505 in the driving component 5 to move. The moving block 505 drives the movable block 506 and the mounting plate 503 for fixing the driving motor 502 to move through the lead screw 504 respectively. The movable block 506 moves along the second chute 3011 through the sliding groove 3012 and the sliding block 5061. The mounting plate 503 moves in the driving cavity 501 along the slide rail 5011 through the first chute 5031. Then the driving motor 501 in the driving component 5 works, and the driving motor 501 drives the lead screw 504 to rotate. The rotating lead screw 504 makes the moving block 505 move along the moving groove 303, and the moving block 505 drives the cleaning plate 302 to move. At the same time, the water pump 601 works to send the water in the water tank 6 into the cleaning plate 302 through the telescopic hose 602 and spray it onto the outer wall of the vehicle from the nozzle 3021, cooperating with the cleaning sponge 3022 to clean the outer wall of the vehicle, so as to complete the cleaning of the outer wall of the vehicle while maintaining the equipment on the top of the vehicle.
