Abstract

The invention discloses a novel tool for replacing a wire side bolt on an overhead transmission line in an electrified mode; the novel tool comprises an insulating operation rod, a bolt tooth-shaped disc connector, a semi-long-hole tooth-shaped disc connector, a butterfly nut, a first gear, a second gear, a gearbox, a first transmission shaft, a second transmission shaft, and sleeve. The novel tool is driven by the gears, and by changing the movement transmission direction, bolts and nuts in different penetrating directions on the side of the wire can be replaced conveniently in an electrifiedmode; the device has the advantages of being easy to operate, safe and reliable, high in working efficiency and the like, and the problem in replacement or fastening of bolts in the clockwise penetrating direction is solved; and due to the adoption of the device, huge economic loss caused by power failure of the overhead power transmission line can be avoided, and technical support for achievingtransmission line live-line repair operation is provided.

Description

technical field [0001] The invention relates to the field of live work on overhead transmission lines, in particular to a new type of tool used for live replacement of wire side bolts on overhead transmission lines. Background technique [0002] As an important part of the power grid, overhead transmission lines play an important role in the power system. There are many types of overhead transmission lines, mainly distributed in open fields, valleys and hills, and river networks. Due to the influence of various natural environments, installation All kinds of fittings on transmission towers often loosen, causing bolts to fall off, leaving hidden dangers for the safe operation of transmission lines. The usual maintenance method is: Daily operation and maintenance personnel find defects during line inspection, send a power outage application to the dispatcher, and after the dispatcher issues a power outage order, the operation and maintenance personnel will go to the tower to p...
