Quick live-line live wire lapping clamp

Abstract

The invention discloses a quick live-line wire lapping clamp. The comprises: a wire clamp main body which comprises a connection section, a hook head located at the upper end of the connection section and an accommodating shell located at the lower end of the connection section, wherein the connection section is internally provided with a slide way; an extrusion assembly, wherein one end of the extrusion assembly is connected into the slide way in a sliding manner; a driving assembly comprising a screw rod penetrating through the containing shell, wherein the upper end of the screw rod is rotationally connected with the lower end of the extrusion assembly; and a locking assembly comprising a folding rod which is hinged in the accommodating shell and a compression spring which is fixed in the accommodating shell. The folding rod comprises a pressing strip and a stirring strip which are connected with each other, and the inner side face of the pressing strip is provided with threads matched with the external thread opening of the screw rod. According to the invention, the operation difficulty of fastening the live wire clamp by the insulating rod can be greatly reduced, so that the operation time and risk can be reduced, meanwhile, the tight contact between the wire clamp and the main wire can be ensured, and the separation is prevented.

Description

technical field [0001] The invention relates to the technical field of electric power engineering, in particular to a fast live wire clamp. Background technique [0002] With the rapid development of the power grid and the continuous improvement of the requirements for power supply reliability in various industries, live work has become an important means of construction and maintenance to effectively reduce user outage time, improve customer service quality, and improve the economic benefits of the power grid. One of the important live-work projects is liveline work (connecting and fixing the drain wire to be externally connected to the main wire of the power grid through a clamp to realize the power-taking process of the drain wire). The work of live-fired distribution network can be carried out by using ground potential insulating rod method, intermediate potential insulating rod, and insulating gloves. Currently, there are many live-fired methods and clamps, among which ...

AI Technical Summary

Problems solved by technology

[0003] The line clamp needs to be installed on site with the insulating rod, but the currently used live loading and unloading line clamp has the following disadvantages: when installing the line clamp, it is fixed on the main line by rotating the bolt at the end of the insulating rod, but because the operating object is 10KV It is very difficult to operate the live fire operation. If the bolt is rotated only by the insulating rod, the connecting part of the insulating rod will slide, making it difficult to exert the rotating torque, resulting in the main wire and the clamp not being in close contact, making it difficult for the clamp to connect with the main wire. The problem of close contact, and it takes a long time; at the same time, when using the insulating rod to twist and tighten, do not use a lot of force, otherwise the connecting parts of several insulating rods will be twisted.
