An auxiliary device for hanging grounding wires during electric power maintenance

Abstract

The invention discloses auxiliary equipment for hanging a ground wire during electric power overhaul. The auxiliary equipment comprises an overhauling trolley, wherein the top of the overhauling trolley is fixedly connected to a fixing plate; a plurality of groups of supporting components are arranged on the fixing plate; an operation rod is arranged in each supporting component; each supporting component comprises a hollow vertical column, a movable bolt, a pressure spring and a supporting seat; the overhauling trolley is in threaded connection with a half-threaded bolt; a non-threaded area of the half-threaded bolt is connected to a rotating piece in a sleeved mode; a sleeve rod is hinged to the rotating piece; the sleeve rod is connected to a ground anchor movable rod in a sleeved mode;and one end of the ground anchor movable rod is fixedly connected to a force application rod while the other end of the ground anchor movable rod is fixedly connected to a spiral ground anchor. The auxiliary equipment is simple in structure and convenient to use, the plurality of groups of supporting components are arranged on the overhauling trolley and a plurality of operation rods can be contained, so that the auxiliary equipment is suitable for large-scale electric power overhaul work; the horizontal height of each operating rod is changed through the corresponding pressure spring, so that the operation of repeatedly walking up and down stairs of an operator is reduced; and furthermore, the overhauling trolley can be fixed on the slope through the spiral ground anchor, so that the practicability is improved.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to an auxiliary device for hanging a grounding wire during electric power maintenance. Background technique [0002] The grounding wire hanging is a type of work often used in electric power maintenance work. The operation process is to hang three grounding operating rods of different phases connected with each other by cables to the line to be tested for testing. It is not difficult to install the cable, but once the height of the installation site exceeds the length of the converging ends of the cables, the difficulty of installation will increase significantly. The main difficulty is that the grounding wires need to be installed in phases. When the operator is installing the ground wires of the first phase, the other two phases are placed in the air or placed on the ground. In this way, when the height of the place where the grounding wire is hung is too high, t...

AI Technical Summary

Problems solved by technology

The weight of the entire wiring device includes not only the weight of the ground wire operating rod, but also the weight of the cable wires. In addition, due to the influence of factors such as the height of the installation and the narrow space, it is very easy for personnel to fall and touch the wires during the operation of the escalator.
