[0029] In summary:

[0030] In use, the staff first pushes the bogie to be repaired into the top frame 5 through the track 21. The design of the track 21 ensures smooth entry and exit of the bogie, greatly improving the convenience of operation. Then, the staff moves the bogie to one side of the bearing plate 10 and prepares to fix it. At this time, the clamping plate 12 is already sleeved on the two threaded rods 11, but has not been tightened. The staff rotates the threaded sleeve 13 to gradually move the clamping plate 12 along the threaded rods 11 to the bogie until the clamping plate 12 and the bearing plate 10 firmly position the bogie at the designated position. Not only does it ensure that the bogie does not move during repair, but it also improves the accuracy and safety of the repair. After completing the fixation of the bogie, the staff starts the pump body 19. The pump body 19 pumps clean water or cleaning liquid into the connecting pipe 15 through an external water source. The connecting pipe 15 uniformly distributes the water flow to the two spray pipes 6, and finally uniformly sprays it from the nozzles of the spray pipes 6, directly acting on the surface and components of the bogie. The water flow distribution is more uniform, improving the cleaning effect. At the same time, the staff can also adjust the spray angle of the spray pipe 6 and the working pressure of the pump body 19 according to the needs to achieve the best cleaning effect. During the cleaning process, the waste water generated is filtered by the filter plate 20 and flows into the bearing box 2. When it is necessary to clean the waste water in the bearing box 2, the staff can open the door body 3 and discharge the waste water through the valve body 4. This design makes waste water treatment more convenient, effectively prevents waste water from accumulating in the repair platform, and maintains the cleanliness and hygiene of the repair environment. In addition, the repair platform also has the function of moving the bogie. When it is necessary to clean or replace the filter plate 20 carrying the bogie, the staff can start the drive motor 7. The output shaft of the drive motor 7 drives the screw 8 to rotate through the rotating shaft and bearing sleeve, and the rotation of the screw 8 drives the nut seat 9 to move along the screw 8 through the screw thread, thereby moving the bearing plate 10 and the bogie fixed on the bearing plate 10 together. The automatic movement of the bearing plate 10 and the bogie on it improves the repair efficiency and reduces the labor intensity of the staff. During the movement of the bearing plate 10, the connecting block 16 slides between the side walls of the top frame 5 through the side slot 22, and the sliding block 17 slides between the inner walls of the side slot 22 through the sliding slot 18. This design provides stable support and guidance for the bearing plate 10, making the movement of the bearing plate 10 more stable and smooth. The sliding block 17 always slides in the sliding slot 18, providing additional support and stability to the bearing plate 10, preventing it from shifting or shaking. This further improves the stability of the bearing plate 10, ensuring the safety and accuracy of the bogie during repair, and also prolongs the service life of the repair platform. First, the design of the track 21 and the clamping plate 12 realizes the convenient pushing and firm fixation of the bogie, improving the accuracy and safety of the repair. Second, the cooperation of the pump body 19, the connecting pipe 15 and the spray pipe 6 realizes the uniform cleaning of the bogie, improving the cleaning effect.Furthermore, through the design of the bearing box 2, the door body 3 and the valve body 4, the wastewater treatment is more convenient, and the cleaning and sanitation of the maintenance environment are maintained. In addition, through the cooperation of the driving motor 7, the screw rod 8 and the nut seat 9, the automatic movement of the bearing plate 10 and the bogie thereon is realized, and the maintenance efficiency is improved. Finally, through the design of the connecting block 16, the sliding block 17 and the side groove 22, the sliding groove 18, the stability of the bearing plate 10 is improved, the safety and accuracy of the bogie during maintenance are ensured, and the service life of the maintenance platform is also prolonged.
