Both ends of the drum 21 are inserted into the driving flange 23 and the driven flange 24, and a first driving source 25 is provided at one end of the driving flange 23 to drive the drum 21 to rotate between the driving flange and the driven flange 24. As a preferred solution of the present utility model, bearings are provided at both ends where the drum 21 is connected to the driving flange 23 and the driven flange 24. When the lifting assembly 2 is assembled with the support assembly 1, it is mainly connected through the hanging beam 22 at the top and the main beam 11. Specifically, the entire main beam 11 is of a trough-shaped structure, with the trough opening facing downwards for installation. The hanging beam 22 is embedded in the trough opening of the main beam 11. Connecting holes for assembly are provided on both the main beam 11 and the hanging beam 22. The support shaft 13 is passed through the connecting holes to connect the lifting assembly 2 at the bottom with the support assembly 1 at the top. As a preferred solution of the present utility model, two groups of support shafts 13 are provided to ensure the stability of the overall assembly structure. Since it is only fixed through the support shaft 13, the entire lifting assembly 2, as a single unit module, can be connected to main beams 11 of different structures and is also applicable to standard clearance hoists with a single-beam structure.

[0031] In the present utility model, the lifting assembly 2 is integrally suspended under the bottom of the main beam 11 and then connected and fixed through the support shaft 13, greatly reducing the assembly time. Secondly, the integrated lifting assembly 2, as a single unit module, can achieve universal installation for both single-beam and double-beam structures, realizing modular assembly and reducing the installation steps and installation difficulty.

[0032] Furthermore, the lifting assembly 2 further includes multiple guide rods 26, and the multiple guide rods 26 are all arranged between the driving flange 23 and the driven flange 24.

An active wheel 41 and a driven wheel 42 are provided on each end beam 12. As a preferred solution of the present utility model, the active wheel 41 and the driven wheel 42 are installed on one side of the end beam 12. The rotating shaft is fixed on the side wall of the end beam 12, which can reduce the installation space. Specifically, the output end of the second driving source 43 is sleeved with a driving gear, and the wheel shaft is sleeved with a driven gear that rotates synchronously with the driving wheel 41.
