General guide wire and earth wire double protection apparatus

Abstract

A general-purpose secondary protection device for guide and ground wires, including a clamping mechanism that can rotate connecting bolts, a U-shaped plate, an automatic telescopic device, a side frame, a pawl, a ratchet wheel, a roller, a steel wire rope, an elastic stop, a hook, Fastening nut, manual handle; the bottom of the clamping mechanism is connected with a rotatable connecting bolt, the side frame is installed on the side of the U-shaped plate, the automatic telescopic device is installed on the upper part of the side frame, and the pawl is arranged on the lower part of the side frame, which is automatically telescopic The device is connected with the pawl; the roller is installed on the U-shaped plate, the right end of the roller has a ratchet, the ratchet is connected with the pawl, and the left end of the roller has a manual handle; the wire rope is wound on the roller, and the lower end of the wire rope is connected There is a hook, and the opening of the hook is provided with an elastic catch. The invention has the advantages of shortening the working time, reducing the labor intensity, avoiding the occurrence of slipping and falling of the wires, ensuring the safety of the wires and ground wires during maintenance operations, and improving economic benefits.

Description

technical field [0001] The invention relates to a construction device for a power transmission line, in particular to a general-purpose secondary protection device for conducting and grounding wires. Background technique [0002] During the power outage operation of the transmission line, dealing with defects on the conductor and the ground wire, replacing the lightning flashover insulator of the transmission line, etc. are often encountered by the team. Poor to lead, ground wire off. [0003] The combined insulating rope secondary protection device currently used is that one end of the hook is hung on the wire, and the other end is wound on the tower material of the iron tower to tie a rope buckle. The safety of the rope buckle of the secondary protection is poor, and the rope body The degree of tightness is difficult to control, resulting in wasting a lot of time when connecting the second protection of the conductor and the ground wire. Contents of the invention [00...
