Pre-twisted wire suspension device for replacing ground wire

Abstract

The invention discloses a pre-twisted wire suspension device for replacing a ground wire. The device comprises a support, wherein a bottom portion of the support is equipped with a lower locking device which can be locked with a cross arm pair, the middle portion of the support is fixedly provided with a main hinge shaft, the main hinge shaft is hinged with a left arm and a right arm which swing up and down at left and right sides, end portions of the left arm and the right arm are equipped with pulley sets, the pulley sets are wound by a pull wire, an upper end of the pull wire is fixedly connected with a wire roller, a lower end of the pull wire is connected with a wire sleeving device in sleeving matching with the ground wire, and an upper portion of the support is provided with a control mechanism used for controlling coiling and uncoiling of the pull wire. The device is advantaged in that rapid mounting and fastening on the high-altitude cross arms can be carried out, assembling is rapid, force-saving suspension is realized, the relatively large operation space is provided for replacing the ground wire metal tool, the ground wire is excellently protected, damage to the groundwire is avoided, operation is simple, and high safety is realized.

Description

technical field [0001] The invention relates to a suspension device for replacing pre-twisted wires of ground wires. technical background [0002] The ground wire clamp is installed on the outer layer of the ground wire to fix the ground wire on the ground wire support of the tower. The ground wire clip protection line has a protective effect on the ground wire. Under the action of the magnetic field of the power line conductor, the guard bar will produce dry-band arc discharge, which will cause the electric corrosion of the guard bar. Under the action of direct lightning and induced lightning, the metal in direct contact with lightning is likely to melt due to high temperature, resulting in damage to wire clips and protective wires. The development of special tools for replacing ground wire fittings is of great significance to the safe, stable and reliable operation of the power grid, ensuring the safety of operators, and improving the quality and efficiency of operation a...

Problems solved by technology

When replacing, it is necessary to use wire rope sleeves and wooden stakes as the cross-arm fixing device, and use a hand hoist to tighten the ground wire. Due to the heavy weight of the ground wire, the weight of the tool is heavy, the operation is inconvenient, the labor intensity is high, and the length of the anchor rope is affected by vibration. Hammer installation distance is limited, the versatility is poor, and the hook is easy to cause damage to the ground wire when lifting

[0004] The traditional method of replacing ground wire fittings takes a long time to work at heights, the labor intensity of the operators is high, and the work efficiency is low. At present, there is still a lack of convenient ground wire fitting replacement bracket tools
