A device for supporting power transmission wires during pole replacement

Abstract

The invention discloses a device for supporting a transmission conductor in the process of replacing an electric pole. The device comprises a movable lifting frame, a lifting plate, cross beams and positioning clamping groove plates. The lifting plate is fixed to the top end of the movable lifting frame. At least two cross beams are arranged and are fixed to the lifting plate in parallel. Each cross beam is provided with the corresponding positioning clamping groove plate. The positioning clamping groove plates are fixed to the cross beams with openings facing upwards. After a hoop of an angle iron cross arm on the damaged electric pole is demounted, the angle iron cross arm can be lifted through the device, the transmission conductor is erected overhead through the angle iron cross arm, and the process for replacing the damaged electric pole with a new electric pole is simplified. In order to prevent displacement of the angle iron cross arm in the construction process, electromagnets in clamping grooves of the positioning clamping groove plates can be used for pulling and clamping the angle iron cross arm, the angle iron cross arm and the transmission conductor are kept at the original installation positions all the time, operation difficulty is lowered, and the transmission conductor can be conveniently and rapidly fixed to the new electric pole.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance tools. Background technique [0002] In the transmission line facilities, the poles used for overhead transmission lines are distributed widely and in large numbers. Some poles are often deformed and broken, and some of the poles themselves are not up to standard, especially the cement poles that have been weathered by the natural environment for a long time. Cracks; some are damaged by external forces and deformed by vehicle collisions. These sick poles cannot guarantee the normal operation of the transmission line, and there are great safety hazards, so they must be replaced in time. If the wires on the poles are removed, it will increase a lot of workload, making the maintenance operation difficult and the construction efficiency low. To replace a pole without dismantling the wires, the power transmission wire must be pulled out when the damaged pole is pulled out. Suspended...

[0002] In the transmission line facilities, the poles used for overhead transmission lines are distributed widely and in large numbers. Some poles are often deformed and broken, and some of the poles themselves are not up to standard, especially the cement poles that have been weathered by the natural environment for a long time. Cracks; some are damaged by external forces and deformed by vehicle collisions. These sick poles cannot guarantee the normal operation of the transmission line, and there are great potential safety hazards. They must be replaced in time

If the wires on the poles are removed, it will increase a lot of workload, making the maintenance operation difficult and the construction efficiency low. To replace a pole without dismantling the wires, the power transmission wire must be pulled out when the damaged pole is pulled out. hanging overhead

In the prior art, cranes are usually used to lift the wires overhead, but the site terrain of many electric poles is complex, which is not suitable for large cranes to enter, and this construction method is easy to loosen the original transmission wires on the angle iron cross arms. The transmission wire must be fastened
