Tightening device for electric power construction

Abstract

The invention discloses a tightening device for electric power construction. The tightening device comprises a bottom plate and a rope; a travel mechanism is arranged at the lower end of the bottom plate; two vertical plates are fixedly connected with the upper end of the bottom plate; a first rotation shaft is rotatably connected between the two vertical plates; the part of the first rotation shaft between the two vertical plates is coaxially and fixedly connected with a reel; the first rotation shaft penetrates through one of the vertical plates; a tightening mechanism is arranged at the end, located outside the vertical plate, of the first rotation shaft; the tail end of the rope is fixedly connected with a first connection plate; a second connection plate is arranged on the side, far away from the rope, of the first connection plate; the second connection plate and the first connection plate are detachably connected through a bolt; and a fixing mechanism is arranged at the end, faraway from the first connection plate, of the second connection plate. Through setting the travel mechanism, the tightening device can move in mountainous areas; through setting the fixing mechanism and the bolt, an effect of fixing leads can be played; and the fixing mechanism can be dismounted, so that the change is convenient.

Description

technical field [0001] The invention relates to the technical field of wire tightening devices, in particular to a wire tightening device for electric power construction. 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] The wire tightening device in the prior art is gener...

AI Technical Summary

Problems solved by technology

[0003] The wire tightening device in the prior art is generally bulky, and when carrying out construction in some mountainous areas, it is cumbersome to carry, and even requires a lot of staff to carry it, and may cause personal injury to the carrier; there are also wire tightening devices. When the hook is pulling the wire, the uneven pulling force causes the hook to slide back and forth on the wire, which will wear the hook, and the hook may slip off the wire
