Description

A tool for high-altitude live remote control electric tightening of wire clamp bolts for transmission lines

technical field

The invention relates to the technical field of maintenance and construction of power grid transmission lines, in particular to a tool for high-altitude live remote-controlled electric tightening of wire clamp bolts for power transmission lines.

Background technique

In the live work of transmission lines, it is difficult to fasten the suspension clamp bolts and bolt-type tension clamp bolts of the transmission line. The bolt of the suspension clamp is located directly under the suspension insulator, separated from the cross arm by an insulator and hardware, and the bolt-type tension clamp is located about 2 meters away from the edge of the cross arm under the wire side, which is in the dead corner of the maintenance operation. Once the clamp bolt is found If it is loose, the defect must be dealt with immediately, otherwise, failure to deal with the defect in time will cause major accidents such as tripping, disconnection, and tower collapse. Accidents such as disconnection and tower collapse will cause the death of surrounding people and animals by electrocution, large-scale permanent power outages and other major accidents and disasters. It is difficult to realize the bolt tightening of suspension clamp bolts and bolt-type tension clamps in ordinary tower climbing operations. Usually, it is necessary to hook up the soft ladder through equipotential operation. When the clamp bolts are loose, hook up the soft ladder to eliminate The defect is very dangerous. Loose bolts will make the wires dance more, so that the probability of disconnection and tower collapse will increase exponentially, and the difficulty, strength and danger of electricians to deal with defects will also increase. Fastening of suspension clamp bolts and electrical bolts of bolt-type tension clamps is very difficult, labor-intensive, and has a very large safety risk. In the double or multi-circuit erected lines on the same tower, due to insufficient safety distance, the bolt tightening of the suspension clamp bolts and the bolt-type tension clamp can only be completed by applying for a power failure of the line. In order to solve the above problems, it is decided to carry out design rectification on the basis of the existing insulating operating rod, and complete the live tightening work of the suspension clamp bolts and the bolt-type tension clamp electrical bolts. Ensure the safe and stable operation of transmission lines.

The looseness of the bolts of the suspension clamp bolts and the bolt-type tension clamps is a critical defect, which can usually be eliminated by equipotential operation or applying for line power outage. Improve transmission line maintenance efficiency and power supply reliability.

Therefore, a tool for high-altitude live remote-controlled electric tightening of clamp bolts for transmission lines was developed to solve the problems of disconnection and tower collapse caused by loose bolts of suspension clamp bolts and bolt-type tension clamps, improving the efficiency of power transmission operations and reducing labor. strength and reduce the risk of safe operation.
