Pre-wire-twisting winding device for repairing high-voltage power transmission conducting wire

Abstract

The invention provides a pre-wire-twisting winding device for repairing high-voltage power transmission conducting wire. The pre-wire-twisting winding device comprises a winch, a winch motor and a mobile platform, wherein an inner hole is formed in the circle center of the winch, a plurality of through holes are formed in the winch, the through holes are uniformly distributed along the circumferential direction of the inner hole, the winch is formed by splicing a first semicircular winch body and a second semicircular winch body which are symmetrical to each other, a power transmission conducting wire is located in the inner hole through opening and closing of the first semicircular winch body and the second semicircular winch body, the winch motor controls the winch to rotate around the circle center of the winch, and the mobile platform controls the winch to move in the length direction of the power transmission conducting wire. The pre-wire-twisting winding device has the advantagethat the pre-wire-twisting winding device can automatically repair the broken strand of a power transmission conducting wire.

Description

【Technical field】 [0001] The invention relates to a pre-twisted wire winding device for repairing high-voltage transmission wires, and belongs to the technical field of pre-twisted wire winding devices. 【Background technique】 [0002] With the development and progress of society, especially the main power transmission line, it is necessary to avoid power outages as much as possible, otherwise it will bring huge economic losses. In order to avoid this situation, regular maintenance and repairs are usually carried out on the transmission wires. As a high-voltage transmission carrier, the steel-cored aluminum stranded wire is mostly exposed, and it will often be corroded by lightning or weather, resulting in broken strands. The pre-twisted wire repair operation method is currently recognized as "minimally invasive wire surgery", which does not require power outages and has little impact on the operation of the entire line. [0003] At present, the operation method of repairin...

AI Technical Summary

Problems solved by technology

The traditional operation method needs to manually wind several groups of pre-twisted wires group by group, root by pitch, and the final stage of winding each group of repair strips is very laborious due to stress. Environments such as wind, swing, and high altitude will pose a great threat to the physical fitness and life safety of the workers, and its safety is extremely low.

Secondly, due to the technical differences of the operators, the winding quality of the pre-twisted wires will be uneven, and defects may appear again in a short period of time, so that the transmission wires are exposed to the air again, reducing the protection ability of the transmission wires
