Problems solved by technology

At present, most of the traditional thread tensioners are ratchet thread tensioners. The ratchet thread tensioner mainly realizes thread tightening through manual control of the handle, and the efficiency is relatively low.
When the traditional ratchet wire tensioner needs to tighten the wire on both sides, it can only be done by two devices at the same time or the same device repeats the operation twice, which is cumbersome and time-consuming. Unbundling and bundling will cause great damage to the cable

Abstract

The invention relates to the technical field of auxiliary equipment for electric power facilities, and provides a multifunctional wire tensioner for power transmission and transformation lines, which includes a housing and a geared motor. Two sets of wire tensioning devices are symmetrically arranged in the housing, and the wire tensioning device has a gear disengagement mechanism. and anti-reversal mechanism. The beneficial effect is that the regulation of two-way tightening or one-way tightening can be realized, and the efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for electric power facilities, in particular to a multifunctional wire tensioner for power transmission and transformation lines. Background technique [0002] The wire tensioner is mainly used for tightening and withdrawing wires in the erection of power transmission and transformation lines, adjusting wires for poles and towers, and fastening ground wires. At present, the traditional thread tensioner is mostly a ratchet thread tensioner, and the ratchet thread tensioner mainly realizes thread tightening by manually controlling the handle, and the efficiency is relatively low. When the traditional ratchet wire tensioner needs to tighten the wire on both sides, it can only be done by two devices at the same time or the same device repeats the operation twice, which is cumbersome and time-consuming. Unbundling and bundling will cause great damage to the cable. Contents of the inventi...
