Description

Technical Field

[0001] The invention belongs to the technical field of auxiliary equipment for electric power construction lines, and in particular relates to a universal clamp-type single-person wire-winding device. Background Art

[0002] In the process of building and renovating the secondary circuit of the substation, the outer insulation and metal armor layer of the secondary cable need to be stripped. Due to the complex wiring of the secondary circuit, there are a large number of secondary cables such as signals, control, and power, and the operation site is multi-faceted and wide. After the cable stripping is completed, the core is often bent and deformed due to the movement of personnel and the handling of equipment. In order to ensure the simplicity and clarity of the secondary circuit and provide convenience for the maintenance of the operating personnel and the subsequent maintenance of the relay protection personnel, the on-site operators need to straighten the cable core first, and then connect it to the device and terminal block. Nowadays, most of the wire straightening methods are carried out by two people. One person stands at the root of the cable and fixes it with his feet, and the other person uses pliers to straighten the other end of the core several times to achieve the purpose of straightening the wire. Because there are a large number of secondary cables, this method not only requires the cooperation of multiple people, but also wastes manpower and seriously affects the progress of the project. And because the root of the core needs to be fixed, the wire needs to be flush with the ground, and the probability of hand injuries to the wire pullers is extremely high. Therefore, a labor-saving and convenient wire straightening method is urgently needed. Summary of the invention
