[0020] In this embodiment, the lifting device includes two mounting covers 1 for fixing and supporting the entire device. Four rollers 2 are respectively arranged on the two mounting covers 1, so that the device can be easily moved and positioned. Two support plates 3 are fixedly mounted on the mounting covers 1 to provide a stable support foundation for the device. The mounting frame 4 is fixedly mounted on the support plate 3 as a mounting platform for the lifting mechanism. The scissor lift assembly 5 is arranged on the mounting frame 4, and a smooth lifting movement is achieved through its special mechanical structure.

Two adjustment mechanisms are respectively installed on the two movable plates 13 to adjust the height of the lower end of the movable plate 13. The support mechanism can better limit the roller 2 to ensure the stability of the lifting device. By using this optimized support mechanism, after the lifting device moves to the working position, the rotating motor 11 can drive the bidirectional screw 9 to rotate, so that the movable plate 13 moves to the appropriate position and contacts the roller 2.

By rotating the adjusting screw 19, the driving block 17 can be driven to move up and down relative to the positioning block 18. The adjusting motor 20 serves as a driving source. By controlling the rotation of its output shaft, the adjusting screw 19 can be driven to rotate, thereby pushing the connecting plate 14 fixedly mounted with the driving block 17 to move up and down, so that the pad 15 is lowered to the height below the roller 2, the movable plate 13 drives the pad 15 to contact the roller 2, and the hydraulic rod 6 is retracted to make the bottom of the pad 15 contact the ground, and the roller 2 is placed between the pad 15 and the movable plate 13.

[0027] In a further preferred embodiment of the utility model, two limiting grooves 21 are respectively formed on the two installation covers 1 , and the limiting grooves 21 are slidably connected to the movable plate 13 .

[0030] In this embodiment, the fence 22 is mainly provided for safety protection. When the lifting device is working, the fence 22 can effectively prevent the staff from accidentally falling, thereby ensuring the personal safety of the staff. At the same time, the solid structure of the fence 22 can also resist the impact of external objects to a certain extent, increasing the overall stability of the equipment. An opening is also specially provided on the fence 22, which provides a passage for the staff to get on and off the equipment. Compared with the traditional climbing or bypassing method, this design enables the staff to enter and exit the lifting device more conveniently and quickly, greatly improving the work efficiency.

[0031] In a further preferred embodiment of the present invention, the movable plate 13 and the pad 15 are vertically arranged and are overall arranged in an "L" shape, and the pad 15 and the roller 2 are arranged correspondingly.

[0032] In this embodiment, the movable plate 13 and the pad 15 are arranged vertically, and the whole presents an "L"-shaped structure. This design enables the movable plate 13 and the pad 15 to form a stable supporting structure, thereby enhancing the stability and load-bearing capacity of the entire lifting device. The pad 15 is arranged corresponding to the roller 2.

Combined with the description of the adjustment mechanism and the driving mechanism in the above embodiments, the design of this "L"-shaped movable plate and pad can better cooperate with the adjustment mechanism and the driving mechanism to achieve accurate lifting and stable operation of the lifting device.

[0033] In summary, compared with the relevant technology, the present device realizes the precise adjustment of the height of the pad 15 set under the movable plate through a unique driving mechanism design.

The present device optimizes the structure of the lifting assembly, adopts a scissor-type lifting method and adds a fence, which not only enhances the stability of the lifting equipment, but also greatly improves safety. The opening design on the fence provides a convenient up and down passage for the staff, reduces labor intensity and improves work efficiency. The "L"-shaped design of the movable plate and the pad and their corresponding relationship with the roller further enhance the stability and load-bearing capacity of the equipment. This design makes the lifting process smoother, avoids deviation or shaking, and thus ensures the accuracy of lifting.
