The tractor is a common tool used in the construction of high-voltage wires. It can pull and tighten the high-voltage wires through an electric hoist or ratchet system to ensure the correct positioning and tension of the high-voltage wires during installation. This equipment helps to ensure the accuracy and safety of high-voltage wire installation. However, the existing high-voltage wire tractors need to be connected with the wire rope and use the winding of the wire rope to pull the high-voltage wire to move. Before using the wire traction rope, a detailed inspection is required to check whether the wire rope is worn. The structure and surface of the tractor should be checked. Only when there is no problem can the equipment be used. This traction tool is composed of a hook, a wire rope, a handle, a parallel claw, a ratchet, a pawl, a spring and other components. During operation, it is necessary to move the spring sheet to the other side, and then press the parallel claw with your hand to pull out the wire rope. It needs to be used in conjunction with a wire clamp. The wire clamp clamps the wire, and then the hooks at both ends of the tractor are fixed, and the wire rope is tightened by pulling the handle. The connection head of the steel wire rope and the high-voltage wire is fixed by a wire clamp, which is easy to damage the cable end, and the connection effect is poor and easy to fall off. In view of this, the existing problems are studied and improved, and a traction device for high-voltage wire erection is provided to solve the existing problems. The purpose is to solve the problems and improve the practical value through this technology. Utility Model Content
