[0002] During the installation of underground electromechanical equipment, it is usually necessary to lay cables. During the laying process, the cables need to be pulled so that the cables can enter the pipeline or be pulled out from the pipeline. Initially, this was done by manpower, which was time-consuming and laborious. Later, traction equipment appeared to replace manual pulling and installation of cables.

[0003] In the prior art, a Chinese utility model patent document with authorization announcement number CN213326050U discloses a pulling device for cable installation, in which a cable channel is formed between the tracks of the upper and lower cable pulling mechanisms, and the cables are pulled by rotating the tracks. However, in actual application, the cable diameters of different devices vary, and the width of the cable channel formed between the tracks of the two cable pulling mechanisms is fixed, so that the device can only be used for pulling cables of one diameter. Different pulling devices are required for the installation of different cables, which is inconvenient to use and has high cost.

[0004] Therefore, it is necessary to design a pulling device for installing cables of underground electromechanical equipment that can adjust the pulling force for cables of different diameters, improve the convenience of construction, and reduce construction costs to solve the current technical problems.
