Overhead ground wire hanger

Abstract

The invention provides an overhead ground wire hanger. Through additionally arranging an inserting inlet channel, a guide outlet channel and a fixing chuck at the corner of the traditional lifting rope winding drum, the lifting rope is lifted to be fixed in a more stable state, happening of several serious safety accidents causes by falling in the case of winding only traditionally can be avoided,and the life and health safety of an electrician is protected; through additionally arranging an auxiliary guide frame plate, a vertical guide column, an upper elastic buffer spring and a lower elastic buffer spring, when a hook hangs a cable to walk upwardly, as an upper force applying connection rod and a lower force applying connection rod have the same rod lengths and the other ends of the two are together hinged onto a lifting seat, the lifting seat provides an acting force for the upper force applying connection rod and the lower force applying connection rod, an upper lifting guide sleeve and a lower lifting guide sleeve are driven under guide of the vertical guide column to move upwardly slowly, the lower elastic buffer spring is further pulled to generate elastic elongation deformation, and the upper elastic buffer spring is squeezed to generate elastic shortening deformation.

Description

technical field [0001] The invention relates to the field of electric equipment, and more specifically, to an overhead ground wire hanger. Background technique [0002] The overhead ground wire is erected above the transmission line and laid to prevent the transmission line from being directly struck by lightning. It can be called a lightning protection line or a ground wire. As the coverage of overhead transmission lines continues to expand, the probability of lightning strikes on transmission lines is also increasing. Since ancient times, thunder and lightning have been incompatible, and the overhead ground wire is a barrier between thunderclouds and power transmission lines. The transmission line spans a wide area, and it is easy to be struck by lightning in the thunderstorm season, which will cause interruption of power transmission, which has become one of the main reasons for power outages in the power system. The installation of overhead ground wires on transmission...

Problems solved by technology

[0004] At present, in the field construction work of the electric power system, especially in the construction of the overhead ground wire of the high-voltage power transmission line, in order to lift the overhead ground wire, the commonly used method of lifting the wire is still the method of manual shouldering, without a special tool

This traditional heavy construction method has many shortcomings and deficiencies. Because it is a high-altitude operation, the weight of the overhead ground wire is very heavy, and the ground wire sometimes moves, so the use of shoulders often causes physical damage to the construction workers; in the above During the construction work, two people are required to coordinate the operation, the labor intensity is high, there are hidden dangers of safety, and the problem needs to be solved
