Description

Technical Field

[0001] The present invention relates to the technical field of wire maintenance equipment, and particularly relates to a double-conductor pulley for a transmission line. Background Art

[0002] At present, the repair of transmission line conductors and lightning conductors usually adopts the pulley wire outlet method for repair;

[0003] When repairing a single-phase double-conductor line, the pulley is usually placed on the lower conductor or the corresponding conductor of this phase for repair. After the wire comes out of the pulley and is at a certain distance from the insulator, due to gravity, the distance between the conductor where the pulley is located and the other conductor of this phase increases, and maintenance cannot be carried out; especially when installing spacer dampers on the line, since the two ends of the spacer damper need to be installed on two different conductors respectively, the problem is more obvious. Ground personnel need to use ropes to pull the conductors closer and then carry out maintenance. This working method has many unsafe factors, requires a large number of personnel, has high requirements for the terrain of the working area, and has low work efficiency. Therefore, the present invention proposes a double-conductor pulley for a transmission line to solve the problems existing in the prior art. Summary of the Invention
