[0003] The existing lifting and maintenance platforms lack supporting reinforcement structures on both sides and adjustable supporting structures at the bottom of the maintenance platforms during lifting and use, which may cause the platforms to tip over during use, affecting the safety of use of the maintenance platforms. In addition, since the maintenance space of the maintenance platforms is relatively fixed, the workers' movable range is limited, affecting the functionality of the platform during use. Therefore, a mechanical maintenance lifting platform with a protective function is proposed to solve the above problems. Utility Model Content

[0025] In this embodiment, the support sleeves 31 and the lifting plate 35 on both sides can support the lifting frame 4, and the multi-stage electric telescopic rod 32 can support the side plate 33, and when the multi-stage electric telescopic rod 32 pushes the moving wheels 36 on the lifting plate 35 to separate from the ground, the lifting frame 4 can be supported by the bottom plate 1, thereby improving the stability and safety of the entire lifting platform.

[0026] Among them, connecting grooves 37 are opened on one side and the other side of the lifting frame 4, and the connecting frame 34 is slidably connected to the inner side of the connecting groove 37. The connecting groove 37 and the connecting frame 34 are both U-shaped and have matching specifications, so that the connecting frame 34 can slide stably in the connecting groove 37.

[0027] In addition, the lower end of the connecting frame 34 is fixedly connected to a slider whose end extends to the inside of the lifting frame 4. The lifting frame 4 has a sliding groove whose end is connected to the connecting groove 37 and is located on the outside of the slider. The sliding groove located on the inside of the sliding groove is used to limit the sliding range of the connecting frame 34 so that the connecting frame 34 and the lifting frame 4 will not separate.

[0028] Secondly, a through hole is opened inside the base plate 1, one end of which is connected to the support sleeve 31 and is located on the outside of the lifting plate 35. There are two support sleeves 31, and the two support sleeves 31 are symmetrically distributed on the base plate 1, so that the support sleeves 31 on both sides support the lifting plate 35 and stably support the lifting frame 4 through the lifting plate 35.

[0029] See also Figure 2 Or 4, in this embodiment, the limit member 5 includes a hinge block 52 with one end fixedly connected to the outer side of the support sleeve 31, the inner side of the hinge block 52 is fixedly connected to a limit block 55 with one end penetrating the support sleeve 31 and extending to the inside of the lifting plate 35, the outer side of the rotating block 54 is fixedly connected to a connecting rope 53 with one end penetrating the lifting frame 4, and one end of the connecting rope 53 penetrating the lifting frame 4 is fixedly connected to the connecting block 51.

[0030] In this embodiment, the activated multi-stage electric telescopic rod 32 can push the side plate 33 and the connecting frame 34 to slide toward the side away from the lifting frame 4 to support the internal space of the lifting frame 4, and by pulling the connecting block 51, the limit block 55 is driven to separate from the lifting plate 35.

[0034] Since the support sleeves 31 and the lifting plates 35 on both sides can support the lifting frame 4, and the multi-stage electric telescopic rod 32 can support the side plate 33, and when the multi-stage electric telescopic rod 32 pushes the moving wheels 36 on the lifting plate 35 to separate from the ground, the lifting frame 4 can be supported by the bottom plate 1, thereby improving the stability and safety of the entire lifting platform. Since the limit block 55 on the rotating block 54 extends into the interior of the lifting plate 35, it can limit the lifting and lowering of the lifting plate 35. Therefore, the started multi-stage electric telescopic rod 32 can push the side plate 33 and the connecting frame 34 to slide toward the side away from the lifting frame 4 to support the internal space of the lifting frame 4. By pulling the connecting block 51 to drive the limit block 55 to separate from the lifting plate 35, the continued started multi-stage electric telescopic rod 32 can push and pull the lifting frame 4 to lift and lower, thereby improving the functionality of the entire lifting platform.
