The upper end of the car body 1 is provided with a lifting platform 2. The lifting platform 2 and the car body 1 are connected to each other through a lifting structure 3. The upper end of the lifting platform 2 is installed with a sensing platform 7. Pressure sensors 8 are provided between the lower surface of the sensing platform 7 and the four corners of the upper surface of the lifting platform 2. Both ends of the lower surface of the lifting platform 2 are fixedly connected with fixed rods 9. The inner side of the fixed rod 9 is provided with a sliding groove 10. One end of the inner part of the sliding groove 10 is fixedly connected with a driving motor 11. The output end of the driving motor 11 is transmission-connected with a threaded screw 12. The surface of the threaded screw 12 The sliding block 13 is threadedly connected, and the lower surface of the sliding block 13 is fixedly connected with a counterweight block 14. Through the counterweight block 14 and the pressure sensor 8, the pressure on the upper surface of the lifting platform 2 is sensed through the sensing platform 7 during use, and the counterweight block 14 on the lower surface of the lifting platform 2 slides toward the lighter end, thereby ensuring the stability of the overall structure of the maintenance platform, and effectively avoiding the traditional platform after it is raised to a certain height.

Since maintenance work is often carried out at high altitudes, the tilt of the platform greatly increases the safety risks of maintenance personnel and may cause accidents.

[0025] In the present invention, preferably, fences 5 are fixedly connected to four sides of the upper surface of the lifting platform 2 .

[0026] Preferably, a control structure 6 is installed on the inner side of the fence 5 .

[0027] Preferably, the lifting structure 3 is electrically connected to the power supply through the control structure 6. When the lifting structure 3 is set up, the lifting and lowering of the lifting structure 3 is electrically controlled by controlling the control structure 6 during use, thereby driving the lifting platform 2 at the upper end to be lifted and lowered, thereby achieving the purpose of maintaining container spreaders at different heights.

[0031] Working principle and use process of the utility model: When using the container spreader maintenance platform of the utility model for maintenance, first, the operator lowers the lifting platform 2 to the lowest position through the control structure 6 so as to move the platform to the bottom of the container spreader that needs to be repaired. Then, the operator activates the driving motor of the moving wheel 4 through the control structure 6 to easily move the platform to the designated position. After reaching the position, the operator again controls the lifting platform 2 to slowly rise to the height of the spreader through the control structure 6. During the lifting process, the pressure sensor 8 senses the pressure on the surface of the platform 7 in real time, and maintains the horizontal state of the platform through the sliding adjustment of the sliding block 13 and the counterweight block 14 to ensure safe operation. When the lifting platform 2 rises to the height of the spreader, the operator can remove the spreader from the container and place it on the lifting platform 2. At this time, the fence 5 fixed on the four sides of the upper surface of the lifting platform 2 can prevent the spreader from accidentally slipping and ensure the safety of the operator. The operator can repair the spreader on the lifting platform 2, and control the lifting and lowering of the lifting platform 2 through the control structure 6, so that the operator can reach different parts of the spreader for maintenance. After the maintenance is completed, the operator reinstalls the spreader back to the container and lowers the lifting platform 2 to the lowest position through the control structure 6. Finally, the operator operates the driving motor of the moving wheel 4 through the control structure 6 to move the platform to the next maintenance position or storage position. During the entire maintenance process, the container spreader maintenance platform of the utility model can provide a stable and safe operating environment, effectively improve maintenance efficiency, and reduce operation risks.
