Abstract

The invention discloses a portable tool for replacing a tension wire shockproof hammer in power cut, which solves the problems of high risk, complicated process and low working efficiency of the existing operation method. The tool is characterized by comprising a main insulation tube, a wire side universal hook, a cross arm side universal hook, U-shaped connection plates, a center-through fixing bolt and the like; the two ends of the main insulation tube are connected with the U-shaped connection plates through the center-through fixing bolt; spring washers are arranged in front of the nuts on the two sides of the center-through fixing bolt; and the U-shaped connection plate at one end is connected with the wire side universal hook, and the U-shaped connection plate at the other end is provided with a cross arm side safety wire connection hole and a support rod connection plate and connected with the cross arm side universal hook through a connection rod and a direction adjuster. The tool disclosed by the invention is safe to use, light in weight, convenient to transport, carry and mount, high in stability, flexible to use, convenient to operate and safe and reliable, reduces the labor intensity and operation risk of workers, improves the working efficiency, shortens the power-cut time of the line, and saves the expenses of the overhauling construction operation.

Description

technical field [0001] The invention relates to a replacement tool, more specifically to a tool for replacing a tension wire anti-vibration hammer. Background technique [0002] Due to the influence of weather conditions such as wind, rain, ice, etc., the anti-vibration hammer of overhead transmission line wires is easy to cause corrosion and deformation of the anti-vibration hammer or the breakage of the hammer head, which affects its anti-vibration performance. Especially for old transmission lines, the service life is relatively long, and the damage of wire anti-vibration hammers has an increasing trend year by year, which makes the maintenance work of replacing and installing wire anti-vibration hammers more and more frequent. [0003] During a power outage to replace the anti-vibration hammer for tension conductors, especially when replacing the anti-vibration hammer for single-strand conductors, since the tension insulators are installed horizontally, the distance betw...
