Tightener for electric power engineering cable installation

Abstract

The invention relates to the technical field of tighteners, in particular to a tightener for electric power engineering cable installation, which comprises a fixed frame, two symmetrically arranged L-shaped plates are arranged in the fixed frame, the two L-shaped plates are fixedly connected with the inner wall of the fixed frame, a U-shaped plate is arranged between the two L-shaped plates, and the U-shaped plate is fixedly connected with the fixed frame. A supporting plate is rotationally connected to the center of the bottom of an inner cavity of the fixing frame. Compared with the prior art, the cable tightener is wide in application range, a plurality of cables can be conveniently fastened at the same time, and the problems that in the using process of a traditional cable tightener for electric power engineering cable installation, manual fastening is usually conducted through the cable tightener, manpower is extremely consumed, only one cable can be fastened generally, the installation efficiency is low, and the conventional tightener cannot fasten the cable according to the height of the cable, so that the application range is narrow, and time and labor are wasted.

Description

technical field [0001] The invention relates to the technical field of wire tensioners, in particular to a wire tensioner for cable installation in electric power engineering. Background technique [0002] The wire tensioner, also called the ratchet tensioner, is used to tighten the wires in the construction of overhead line laying. When in use, first loosen the steel wire rope or galvanized iron wire on the wire tensioner, and fix it on the cross arm, clamp the wire with the wire clamp, and then pull the special wrench. Due to the anti-reversal function of the ratchet, the steel wire rope or galvanized iron wire is gradually wound on the ratchet drum to tighten the wire. Fasten the tightened wires to the insulators. Then first release the ratchet to loosen the steel wire rope or galvanized iron wire, then loosen the wire clamp, and finally wind the steel wire rope or galvanized iron wire on the drum of the ratchet. [0003] Cable tighteners are used during the installati...

AI Technical Summary

Problems solved by technology

[0003] Cable tighteners are used during the installation and use of cables, but traditional cable tensioners for power engineering are usually manually tightened with a cable tightener during use, which consumes a lot of manpower and usually only One cable can be fastened, and the installation efficiency is low, and the previous cable tensioner cannot be fastened according to the height of the cable, resulting in a narrow scope of application, and it is time-consuming and labor-intensive
