[0082] Specifically, two adjacent first disk bodies are connected by flanges. This arrangement facilitates assembly and disassembly of the plurality of first disk bodies, and has a simple structure and convenient operation.

[0083] Furthermore, two adjacent second disk bodies are connected via flanges. This arrangement facilitates assembly and disassembly of multiple second disk bodies, and has a simple structure and convenient operation.

[0084] The connection assembly 40 includes a plurality of connection columns 41, which are spaced apart along the circumference of the first hanging plate 10, and extend in the vertical direction.

[0086] Furthermore, the first disk body and the connecting column 41 adopt a tubular structure. Among them, when the staff works on the working surface of the wellbore, a compressed air system is required to provide compressed air for devices such as a pneumatic drill. In the prior art, it is usually necessary to open a through hole on the lifting device so that the compressed air pipeline can be passed through the through hole, but the space of the lifting device is limited, and opening a through hole is not convenient for the staff to work. However, in the present application, the staff can set an air inlet and an air outlet on the first disk body and the connecting column 41 as needed, and the air inlet and the air outlet are connected to each other, so that the air inlet is connected to the compressed air system, and the air outlet is connected to devices such as a pneumatic drill, and the staff can set control valves at the air inlet and the air outlet as needed. Therefore, the technical solution of the present application can avoid the provision of through holes, simplify the structure, and facilitate the delivery of compressed air.
