Universal spiral compaction type grounding wire operating rod

Abstract

The invention discloses a universal spiral compaction type grounding wire operating rod. The universal spiral compaction type grounding wire operating rod is characterized by comprising a lead clamp assembly, an adjusting assembly, an operating rod assembly and a transmission handle assembly which are sequentially connected, and further comprising an insertion type connector used for connecting an insulation operating rod and a limit stop nail, wherein lead clamps are provided with screws and spiral compaction bolts connected with universal joints and clamp heads connected with a steel wire transmission soft shaft, the adjusting assembly comprises supporting pipes used for fixing the universal joints and the steel wire transmission soft shaft, the operating rod assembly comprises the insulation operating rods and insulation transmission rods which are arranged in the insulation operating rods and are connected with the steel wire transmission soft shaft and a transmission handle clamp head, and the transmission handle assembly is provided with a thread type connection head used for connecting the operating rods. The universal spiral compaction type grounding wire operating rod is advantaged in that leads are made to be clamped in any adjustment angle of the horizontal direction 360 DEG and the vertical direction about 120 DEG, the quantity of the operating rods is reduced through employing an assembly connection mode, exchange of the lead clamps in different modes is facilitated, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a universal screw-pressing type grounding wire operating lever. Background technique [0002] According to the relevant power safety regulations of the country and the power industry, when the staff is working on the power equipment, a three-phase short-circuit grounding wire must be installed in all directions that may send power to the workplace, which is to protect the staff from sudden calls at the workplace. Reliable safety measures, at the same time, the residual charge of the disconnected part of the equipment can also be exhausted due to grounding. The existing technology is to fix a wire clamp with screw compression on the insulation operation rod, rotate the insulation operation rod to drive the screw to compress the wire (remove the reverse rotation of the insulation operation rod), and connect the soft copper wire to the wire clamp and fix it with a grounding cl...

AI Technical Summary

Problems solved by technology

[0005] Since the wire clamp is fixed at 90 degrees, it only solves the installation of the wire grounding wire perpendicular to the ground, and the installation of wires at other angles is still very difficult, and gear meshing transmission is used, which must be made of metal materials with higher hardness. The wire clamps are all made of aluminum alloy, which is relatively light, which not only increases the weight of the wire clamps, but also makes the lifting operation more difficult, and increases the cost of manufacturing and purchasing
