Description

A kind of telescopic charged dismounting Bird's Nest slide plate and charged dismounting Bird's Nest method

Technical field

The present invention relates to a kind of telescopic charged dismounting Bird's Nest slide plate and charged dismounting Bird's Nest method, belong to overhead power transmission line electrified repair apparatus technical field.

Background technology

In recent years, along with the raising of social environment consciousness, the continuous improvement of natural environmental condition and people love bird, protect the consciousness reinforcement of bird, avian reproduction speed is also constantly accelerated, because the destruction of early stage natural environment is caused tall and big trees scarcity, cause birds cannot look for corresponding natural environment and nest, build Bird's Nest then be chosen on firm, tall and big electric power line pole tower.The frequent activities of birds on transmission line, has brought great harm to the safe operation of transmission line.In order to ensure transmission line safe operation, must remove in time the Bird's Nest on shaft tower, especially the Bird's Nest of insulator string hanging point top.The main material that birds are built nest comprises the foreign material such as branch, iron wire, faggot, and these materials are not insulators.In the time removing Bird's Nest, owing to containing the electric conductors such as a large amount of iron wires in Bird's Nest, after Bird's Nest is broken, these electric conductors fall naturally, very easily touch live wire or fall between line, causing safe distance deficiency between line, wire and iron wire form conductive channel, cause transmission line short circuit dischange, serious threat Bird's Nest is removed personnel's personal safety and transmission line safe operation.

Summary of the invention

The object of the invention is to provide a kind of telescopic charged dismounting Bird's Nest slide plate and charged dismounting Bird's Nest method, and while preventing from removing Bird's Nest, Bird's Nest vertical drop causes transmission line short circuit dischange, solves the problem existing in background technology.

Technical scheme of the present invention is:

A kind of telescopic charged dismounting Bird's Nest slide plate, comprise insulation canvas, insulating cord, insulation tail rope, insulated tube and canvas bracing or strutting arrangement, insulation canvas two ends are separately positioned on two insulated tubes, on an insulated tube, connect insulating cord, on another insulated tube, connect insulation tail rope, insulation canvas below is provided with canvas bracing or strutting arrangement, described canvas bracing or strutting arrangement is to be made up of insulation board end is hinged some, every pair of insulation board is X-type, middle part is hinged, and the insulation board end at two ends is connected with insulated tube end by expansion bracket.

Described expansion bracket comprises expansion link and fixed bolt hole, and expansion link is located in insulated tube, and exposed portions serve is provided with fixed bolt hole.

Described insulation tail rope is provided with hook.

Described insulation board is strip.

A kind of charged dismounting Bird's Nest method, adopts above-mentioned charged dismounting Bird's Nest slide plate to carry out, and comprises following steps:

1. charged dismounting Bird's Nest slide plate is stretched to maximum, the canvas that makes to insulate is smooth;

2. by insulating cord colligation on the cross-arm angle steel of cross arm insulator string hanging point one side, the hook of insulation on tail rope hangs on the angle steel of cross-arm both sides;

3., while removing Bird's Nest, the foreign material in Bird's Nest will skid off along the telescopic charged dismounting Bird's Nest slide plate tilting.

With known general utility tool dismounting Bird's Nest.

The invention has the beneficial effects as follows: can draw in and launch, volume is little, and quality is light, easy to carry, the foreign material vertical drop such as iron wire while having avoided dismounting Bird's Nest, the Bird's Nest that makes to build on shaft tower can smooth charged dismounting.
