Power transmission line double-wire tackle

Abstract

The power transmission line double-wire pulley comprises a mounting plate and wire wheel assemblies, wherein the wire wheel assemblies are arranged on the left side and the right side of the top of the mounting plate correspondingly, each wire wheel assembly comprises supporting plates and a first wire wheel, the supporting plates are divided into a front set and a rear set, and the first wire wheels are rotatably mounted below the position between the front set of supporting plates and the rear set of supporting plates; sliding grooves are formed in the upper portions of the inner sides of the two sets of supporting plates correspondingly, sliding blocks are movably installed in the sliding grooves, a second wire wheel is rotatably installed between the two sets of sliding blocks, threaded lead screws are rotatably installed in the sliding grooves, and the threaded lead screws penetrate through the sliding blocks and are in threaded fit with the sliding blocks. A second wire wheel anda first wire wheel are designed, the second wire wheel is installed on an upper wire, the first wire wheel is installed on a lower wire, the problem that the distance between two wires is large during double-wire line span inner repairing can be effectively solved, the first wire wheel can be driven to rotate by rotating a crank, an operator can move in a more labor-saving mode, operation is moreflexible and convenient, and the repairing efficiency is improved; and working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electric wire maintenance equipment, in particular to a double-conductor pulley for power transmission lines. Background technique [0002] At this stage, the repair of transmission line conductors and lightning conductors is usually carried out by the method of pulling out wires; [0003] When the single phase of the line is repaired with two conductors, the pulley is usually placed on the lower conductor of the phase or the corresponding conductor for repair. After the pulley exits the conductor and the insulator at a certain distance, due to gravity, the distance between the conductor where the tackle is located and the other conductor of the phase is enlarged. Carry out inspection and maintenance; especially when installing spacers on the line, since the two ends of the spacer need to be installed on two different wires, the problem is more obvious, and ground personnel need to use ropes to pull the w...

Problems solved by technology

[0003] When the single phase of the line is repaired with two conductors, the pulley is usually placed on the lower conductor of the phase or the corresponding conductor for repair. After the pulley exits the conductor and the insulator at a certain distance, due to gravity, the distance between the conductor where the tackle is located and the other conductor of the phase is enlarged. Carry out inspection and maintenance; especially when installing spacers on the line, since the two ends of the spacer need to be installed on two different wires, the problem is more obvious, and ground personnel need to use ropes to pull the wires closer and then repair them There are many unsafe factors in the method, more personnel are required, the multi-working area has high terrain requirements, and the work efficiency is low. Therefore, the present invention proposes a double-conductor tackle for power transmission lines to solve the problems existing in the prior art
