A third movable groove is provided at the bottom inside the platform box 1. The third movable groove is arranged below the circular movable groove and the second movable groove, and the bottom of the second threaded rod 10 extends to the inner side of the third movable groove.

[0042] The clamping and lifting assembly 4 also includes a first double-headed motor 11, a first rotating rod 12 and a first bevel gear set 13. The first double-headed motor 11 is fixedly connected to the middle of the inner side of the third movable groove, and the output ends at both ends of the first double-headed motor 11 are fixedly connected to the first rotating rod 12. The end of the first rotating rod 12 away from the first double-headed motor 11 is rotatably connected to the inner side of the third movable groove. A first bevel gear set 13 is provided on the outer side of the first rotating rod 12. The position of the first bevel gear set 13 corresponds to the bottom of the second threaded rod 10, and the first rotating rod 12 drives the second threaded rod 10 to rotate inside the second movable groove through the first bevel gear set 13.

[0043] The clamping and lifting assembly 4 also includes a second rotating rod 14, a second bevel gear set 15 and a third bevel gear set 16. A fourth movable groove is provided on the inner side of both ends of the platform box 1. The second rotating rod 14 is rotatably connected to the inner side of the fourth movable groove. The top of the second rotating rod 14 extends to the inner side of the first movable groove, and the bottom of the second rotating rod 14 extends to the inner side of the third movable groove. A second bevel gear set 15 is also provided on the outer side of the first rotating rod 12. The position of the second bevel gear set 15 corresponds to the bottom of the second rotating rod 14, and the first rotating rod 12 drives the second rotating rod 14 to rotate through the second bevel gear set 15. A third bevel gear set 16 is provided on the top of the second rotating rod 14. The position of the third bevel gear set 16 corresponds to the first threaded rod 7, and the second rotating rod 14 drives the first threaded rod 7 to rotate through the third bevel gear set 16.

[0044] The clamping and lifting assembly 4 also includes a rotating disk 17, a second double-headed motor 18, a third threaded rod 19 and a clamping plate 20. The rotating disk 17 is rotatably connected to the inner side of the lifting platform 8. A fifth movable groove is provided on the inner side of the top of the rotating disk 17. The second double-headed motor 18 is fixedly connected to the middle part of the inner side of the fifth movable groove. The output ends at both ends of the second double-headed motor 18 are fixedly connected to the third threaded rod 19. The two third threaded rods 19 are symmetrically arranged. The end of the third threaded rod 19 away from the second double-headed motor 18 is rotatably connected to the fifth movable groove. Clamping plates 20 are provided at both ends of the top of the rotating disk 17, and the bottom of the clamping plate 20 extends to the inner side of the fifth movable groove and is threadedly connected to the third threaded rod 19.

[0045] Specifically: when not in use, the two blocking plates 6 can block the center movable groove, so that the top surface of the platform box 1 can be kept flat, making it easy to place other items on the top of the platform box 1;

[0046] When the workpiece needs to be clamped and fixed, the first double-headed motor 11 is turned on to drive the first rotating rod 12 to rotate inside the third movable groove, thereby driving the first bevel gear set 13 and the second bevel gear set 15 outside the first rotating rod 12 to rotate synchronously;

[0047] The connection arrangement of the first bevel gear set 13 can drive the second threaded rod 10 inside the second movable groove to rotate synchronously, thereby driving the movable block 9 threadedly connected to the second threaded rod 10 to move upward inside the second movable groove, thereby driving the lifting platform 8 fixedly connected to the movable block 9 to move upward inside the circular movable groove;

[0048] Through the connection setting of the second bevel gear set 15, the second rotating rod 14 can be driven to rotate inside the fourth movable groove, so that the first threaded rod 7 can be driven to rotate inside the first movable groove through the connection setting of the top third bevel gear set 16, thereby driving the fixing rod 5 threadedly connected to the first threaded rod 7 to move laterally inside the first movable groove, so as to achieve the purpose of moving the two blocking plates 6 to one end away from each other and canceling the blocking effect of the two blocking plates 6 on the inside of the circular movable groove;

[0049] The setting of the fixing rod 5 can stabilize the movement of the blocking plate 6 inside the first movable groove;

[0050] At the same time, by continuously moving the lifting platform 8 upward, the two clamping plates 20 can be driven to move to the outside of the top of the platform box 1;

[0051] Then, the workpiece to be repaired is placed between the two clamping plates 20. By turning on the second double-headed motor 18, the two third threaded rods 19 can be driven to rotate inside the fifth movable groove. The two third threaded rods 19 are symmetrically arranged, which can drive the two clamping plates 20 threadedly connected to the third threaded rods 19 to move synchronously and in opposite directions on the top of the rotating disk 17, thereby achieving a clamping effect on both ends of the workpiece to be repaired.

[0052] At the same time, through the rotating connection setting between the rotating disk 17 and the inner side of the top of the lifting platform 8, after the workpiece to be repaired is clamped, it can rotate freely on the top of the platform box 1, thereby avoiding the maintenance workers walking around the platform box 1 for maintenance, thereby improving the convenience of the maintenance platform.

[0053] Example 3:

[0054] This embodiment 3 is used to further disclose the specific structure of the clamping and lifting component 4 on the premise of the above embodiments. Through the coordination of the clamping and lifting component 4 and the structure in the above embodiments, it is achieved that a plurality of movable support rods are provided at the clamping position, which can fit the surface of irregular or curved surfaces, thereby improving the stability of clamping the object and further improving the overall maintenance efficiency.

[0055] The mechanical maintenance platform provided in Example 1 and Example 2 is further optimized. Specifically, Figure 7As shown, the fixed rod 5 includes a movable rod 21, an extrusion pad 22, a limit block 23 and a spring 24. A plurality of circular reserved grooves are provided on the inner side of the clamping plate 20. The inner sides of the circular reserved grooves are clearance-fitted with movable rods 21, and the movable rods 21 are arranged through the clamping plate 20. The end of the movable rod 21 close to the center position of the rotating disk 17 is fixedly connected to the extrusion pad 22, and the end of the movable rod 21 away from the center position of the rotating disk 17 is fixedly connected to the limit block 23. A spring 24 is provided on the outside of the movable rod 21, and the spring 24 is arranged at the end close to the center position of the rotating disk 17. The two ends of the spring 24 are fixedly connected to the extrusion pad 22 and the clamping plate 20 respectively.

[0056] Specifically, when the two clamping plates 20 approach the workpiece to be repaired, the squeezing pad 22 contacts the surface of the workpiece to be repaired. As the workpiece continues to approach, the squeezing pad 22 is squeezed, causing the movable rod 21 to slide inside the circular reserved groove, and squeezing the spring 24 through the squeezing pad 22.

[0057] By the clearance fit between the multiple movable rods 21 and the circular reserved grooves, the multiple squeezing pads 22 can be adaptively adjusted according to the different concave and convex degrees of the surface of the workpiece to be repaired, thereby being able to clamp workpieces with different surfaces to be repaired;

[0058] At the same time, the elastic setting of the spring 24 can continuously support the extrusion pad 22, thereby further improving the extrusion effect of the extrusion pad 22 on the surface of the workpiece to be repaired.
