Universal spiral compaction type grounding wire operating rod

Abstract

The invention discloses a universal screw compression type grounding wire operating rod. The technical solution of the present invention is: including the wire clip assembly, the adjustment assembly, the operating rod assembly and the transmission handle assembly connected in sequence, the wire clip is provided with a screw connected with the universal joint and a screw compression bolt connected with the steel wire transmission flexible shaft The chuck, the adjustment assembly includes a support tube, which is used to fix the universal joint and the steel wire transmission flexible shaft, and is also provided with a plug-in joint and a limit stop nail for connecting the insulating operating rod. The operating rod assembly includes an insulating operating rod and an insulating operating rod. An insulated transmission rod inside the operation rod is connected with the steel wire transmission flexible shaft and the chuck of the transmission handle, and the transmission handle assembly is provided with a threaded connector for connecting the operation rod. The solution provided by the invention allows the wire clip to be adjusted at any angle at 360 degrees in the horizontal direction and about 120 degrees in the vertical direction, and the number of operating rods is reduced by the way of component connection, which facilitates the exchange of different types of wire clips and reduces the cost.

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...

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
