Description

Multifunctional wrench for power transmission line

technical field

The utility model relates to the technical field of power transmission lines, in particular to a multifunctional wrench for power transmission lines.

Background technique

The transmission line is realized by using a transformer to boost the electric energy generated by the generator, and then connecting it to the transmission line through control equipment such as a circuit breaker. Structural forms, transmission lines are divided into overhead transmission lines and cable lines. The overhead transmission line is composed of line towers, wires, insulators, line fittings, guy wires, tower foundations, grounding devices, etc., and is erected above the ground.

During the erection of transmission lines, a wrench is often used to install the bolts in the transmission line. The purpose is to use the principle of leverage to twist bolts, screws, nuts and other threads to hold the bolts tightly, so that the operator can save more effort.

Most of the existing wrenches used for power transmission lines have relatively single functions and can only be used for limited types of bolt tightening work, while some multi-functional wrenches that can meet the use of different types of bolts often add other parts to the original basis of ordinary wrenches. Because it does not have the function of folding and storing, it will bring a certain burden to the personnel when carrying it. For this reason, we propose a multifunctional wrench for power transmission lines.
