Therefore, a lot of time is needed to clean the chassis before repair. Moreover, when the subway is towed outward, there may be debris on the track surface. These debris will be lifted up during the movement of the tractor and fall onto the chassis of the vehicle, which further increases the cleaning time and is not conducive to maintenance.

DETAILED DESCRIPTION

[0017] Reference Figure 1-Figure 8 , a traction AGV device for a subway vehicle, comprising: A tractor 1, a lifting groove 2 is formed on the side wall of the tractor 1, a lifting block 3 is slidably connected between the inner walls of the lifting groove 2, a lifting plate 4 is fixedly connected to the side wall of the lifting block 3, a fixed through groove 9 is formed on the lifting block 3 to penetrate the lifting plate 4, the lifting plate 4 is connected to the subway vehicle, and the tractor 1 is operated to pull the subway vehicle to the outside; like Figure 3 and Figure 4 As shown, the lifting structure 5 includes a rotating shaft 51 rotatably connected to the inner wall of the lifting groove 2, a driver is installed on the rotating shaft 51, the driver adopts a large torque motor, a threaded rod 52 is rotatably connected to the rotating shaft 51 through an adjusting structure, the threaded rod 52 penetrates the lifting block 3 and is rotatably connected to the inner wall of the lifting groove 2, and the threaded rod 52 is threadedly connected to the lifting block 3, a hydraulic device is fixedly installed on the inner wall of the lifting groove 2, and the output end of the hydraulic device is fixedly connected to the lifting block 3; The hydraulic device is started to drive the lifting block 3 to move together, and the lifting plate 4 to move together, so that the end of the lifting plate 4 connected to the subway vehicle is lifted up, and the chassis of the subway vehicle is lifted up, so as to facilitate its maintenance and repair. Since the lifting block 3 cannot rotate, the lifting block 3 moves upward under the action of the thread, so that the threaded rod 52 rotates, and cooperates with the adjustment structure to rotate the rotating shaft 51 together; like Figure 5 and Figure 6As shown, a first cleaning structure 6 is installed inside the lifting groove 2, and the first cleaning structure 6 includes a telescopic rod 62 fixedly connected to the inner wall of the lifting groove 2, and the end face of the telescopic rod 62 is fixedly connected to the extrusion plate 63, and the telescopic rod 62 is built with a reset spring, which can automatically reset the telescopic rod 62, and a fixed cam 61 corresponding to the extrusion plate 63 is fixedly sleeved on the rotating shaft 51, and a mounting block 610 is slidably connected to the extrusion plate 63 to avoid motion interference between the mounting block 610 and the connecting shaft 66, and a mounting shaft 611 is rotatably connected between the inner walls of the mounting block 610, and a connecting block 64 is fixedly sleeved on the mounting shaft 611, and the connecting block 64 extends to the mounting shaft 611. The outer side of the mounting block 610 is fixedly connected with a connecting plate 65, and the connecting plate 65 extends to the outer side of the lifting groove 2. The bottom end of the connecting plate 65 is rotatably connected with a mounting rod 67, and the bottom end of the mounting rod 67 is fixedly connected with a cleaning plate 68. The inner wall of the lifting groove 2 is rotatably connected with a connecting shaft 66, and the connecting shaft 66 is fixedly connected to the connecting plate 65. The connecting shaft 66 and the mounting rod 67 are connected by a belt rotating assembly 69. A torsion spring 612 is fixedly connected between the inner wall of the mounting block 610 and the connecting block 64, and the torsion spring 612 is sleeved on the outer side of the mounting shaft 611. The torsion spring 612 cooperates with the telescopic rod 62 to reset the extrusion plate 63. As the rotating shaft 51 rotates, the fixed cam 61 fixedly sleeved on the rotating shaft 51 rotates accordingly. When the fixed cam 61 rotates, it squeezes the squeezing plate 63 to make it move, and the squeezing plate 63 returns to its original position under the action of the telescopic rod 62. Therefore, the squeezing plate 63 moves back and forth. When the squeezing plate 63 moves, it drives the mounting block 610 to move accordingly, and drives the connecting block 64 and the connecting plate 65 to move accordingly. When the end of the connecting plate 65 connected to the connecting block 64 moves, the connecting plate 65 as a whole rotates with the connecting shaft 66 as the center of the circle, so that the connecting plate 65 rotates back and forth continuously, so that the mounting rod 67 and the cleaning plate 68 rotate back and forth accordingly, and the bottom of the subway vehicle chassis is cleaned, ensuring that when the subway vehicle moves with the tractor 1, no debris will be stuck on the chassis of the subway vehicle; like Figure 7 and Figure 8 As shown, a second cleaning structure 7 is installed on the lifting block 3, and the second cleaning structure 7 includes a fixed block 71 fixedly connected to the lifting block 3, a fixed plate 72 fixedly connected to the fixed block 71, a fixed cylinder 73 rotatably connected to the inner wall of the fixed plate 72, a fixed pipe 74 rotatably installed on the inner side of the fixed cylinder 73, the fixed pipe 74 extends to the outer side of the fixed cylinder 73 and is rotatably connected to an air jet nozzle 78, an air guide pipe 75 communicating with the interior of the fixed pipe 74 is fixedly connected to the fixed pipe 74, and the fixed pipe 74 is fixedly connected to an air pump through the air guide pipe 75, the air pump is a prior art, which is installed inside the tractor 1, the air guide pipe 75 adopts a hose, a fixed gear 76 is fixedly sleeved on the fixed cylinder 73, a fixed rack 77 is fixedly connected to the inner wall of the lifting groove 2, and the fixed rack 77 passes through the fixed through groove 9 and meshes with the fixed gear 76; The air pump pumps the gas from the air guide pipe 75 into the fixed pipe 74, and then sprays it out from the jet nozzle 78. When the airflow is sprayed out, it will wash the chassis of the subway vehicle and wash away the dust and other debris on the chassis. At the same time, the fixed pipe 74 will move with the lifting block 3, so that the airflow sprayed from the jet nozzle 78 can clean the chassis of the subway vehicle during the operation of the tractor 1, so that the chassis is kept clean, so that the maintenance personnel can maintain it. A fixing plate 79 is fixedly sleeved on the fixing cylinder 73, and a fixing rod 710 is fixedly connected between the fixing plate 79 and the side wall of the air jet nozzle 78. The air jet nozzle 78 is in an inclined state, and a sealing gasket is fixedly installed at the connection between the air jet nozzle 78 and the fixing tube 74 to prevent air leakage; As the lifting block 3 moves, the fixed block 71 and the fixed plate 72 move together, and the fixed cylinder 73 also moves accordingly. The upper fixed gear 76 fixedly sleeved on the fixed cylinder 73 moves along with the fixed cylinder 73. Under the action of the fixed rack 77, the fixed gear 76 rotates when moving, driving the fixed cylinder 73 to rotate together. When the fixed cylinder 73 rotates, it drives the fixed plate 79 to rotate together, so that the fixed rod 710 and the jet nozzle 78 rotate accordingly. Since the jet nozzle 78 is inclined and no longer in the same straight line with the fixed pipe 74, the direction of the jet airflow will change when the jet nozzle 78 rotates, thereby increasing the area of ​​the airflow ejection and expanding the cleaning range. like Figure 4 As shown, the adjustment structure includes a fixed slot 57 opened on the rotating shaft 51, a fixed tooth 53 matching the fixed slot 57 is slidably sleeved on the threaded rod 52, a rotating ring 56 is rotatably connected to the fixed tooth 53, an adjusting rod 54 is fixedly connected to the rotating ring 56, the adjusting rod 54 passes through the lifting block 3 and is slidably connected to the lifting block 3, and an adjusting block 55 is fixedly installed on the top of the adjusting rod 54. In the initial state, the fixed tooth 53 is located inside the fixed slot 57, so that the rotating shaft 51 and the threaded rod 52 are connected together; When the tractor 1 moves to a suitable position, the maintenance personnel perform maintenance on the subway vehicle. At this time, the lifting block 3 moves upward to the highest position. During the movement, the lifting block 3 contacts the adjusting block 55 and pushes the adjusting block 55 upward, thereby driving the adjusting rod 54 and the fixed tooth 53 to move upward together, so that the fixed tooth 53 moves to the outside of the fixed groove 57. At this time, the rotation of the threaded rod 52 no longer rotates the rotating shaft 51, so that the first cleaning structure 6 no longer operates, avoiding interference to the maintenance personnel. like Figure 1 and Figure 2As shown, a fixed structure 8 is fixedly installed on the lifting plate 4. The fixed structure 8 is a conventional fixed structure. The lifting plate 4 and the chassis of the subway vehicle are connected by components such as a towing hook; an operation panel and a remote control antenna are fixedly installed on the tractor 1. The operation panel and the remote control antenna are existing technologies, so their working principles are not elaborated. The operation panel and the remote control antenna are both used to control the movement of the tractor 1.

[0018] In the present invention, the tractor 1 is first moved to the subway vehicle, and the chassis of the subway vehicle is connected to the lifting plate 4 through the fixing structure 8 on the lifting plate 4. Then, the tractor 1 moves to drive the subway vehicle to move together, so that the subway vehicle is moved to an open area, so as to facilitate the repair of the subway vehicle. At the same time, the hydraulic device is started to drive the lifting block 3 to move, thereby driving the lifting plate 4 to move together, so that the end of the lifting plate 4 connected to the subway vehicle is lifted up, so that the chassis of the subway vehicle is lifted up, so as to facilitate its maintenance and repair. Since the lifting block 3 cannot rotate, the lifting block 3 moves upward under the action of the thread, which causes the threaded rod 52 to rotate, and the rotating shaft 51 rotates under the cooperation of the fixed slot 57 and the fixed tooth 53; As the rotating shaft 51 rotates, the fixed cam 61 fixedly sleeved on the rotating shaft 51 rotates accordingly. When the fixed cam 61 rotates, it squeezes the squeezing plate 63 to make it move, and the squeezing plate 63 returns to its original position under the action of the return spring in the telescopic rod 62. Therefore, the squeezing plate 63 moves back and forth. When the squeezing plate 63 moves, it drives the mounting block 610 to move accordingly, and drives the connecting block 64 and the connecting plate 65 to move accordingly. When the end of the connecting plate 65 connected to the connecting block 64 moves, the connecting plate 65 as a whole moves with the connecting shaft 66 as the The center of the circle rotates, so that the connecting plate 65 rotates back and forth continuously, so that the mounting rod 67 and the cleaning plate 68 swing back and forth accordingly, and the lower part of the subway vehicle chassis is cleaned, ensuring that when the subway vehicle moves with the tractor 1, no debris will be stuck on the chassis of the subway vehicle, and the connecting shaft 66 will rotate together with the connecting plate 65. Under the action of the belt transmission component 69, the rotation of the connecting shaft 66 will drive the mounting rod 67 to rotate together, so that the cleaning plate 68 rotates back and forth during the back and forth swinging process, further improving its cleaning effect; Moreover, the lifting block 3 moves upward, the fixed block 71 and the fixed plate 72 move upward together, and the fixed cylinder 73 also moves upward accordingly. The upper fixed gear 76 fixedly sleeved on the fixed cylinder 73 moves with the fixed cylinder 73. Under the action of the fixed rack 77, the fixed gear 76 rotates when moving, driving the fixed cylinder 73 to rotate together. When the fixed cylinder 73 rotates, it drives the fixed plate 79 to rotate together, so that the fixed rod 710 and the jet nozzle 78 rotate accordingly. Since the jet nozzle 78 is inclined and is no longer in the same straight line with the fixed pipe 74, the direction of the jet airflow will change when the jet nozzle 78 rotates, thereby increasing the area of ​​the airflow spraying and expanding the cleaning range. The dust and debris washed down by the airflow will fall below the lifting plate 4 and be cleaned up by the cleaning plate 68; When the tractor 1 moves to a suitable position, the maintenance personnel perform maintenance on the subway vehicle. At this time, the lifting block 3 moves upward to the highest point. During the movement, the lifting block 3 contacts the adjusting block 55 and pushes the adjusting block 55 upward, thereby driving the adjusting rod 54 and the fixed tooth 53 to move upward together, and allowing the fixed tooth 53 to move to the outside of the fixed groove 57. At this time, the rotation of the threaded rod 52 no longer rotates the rotating shaft 51, so that the first cleaning structure 6 no longer runs, avoiding interference to the maintenance personnel.
