Rotary overhead conductor opening device

Abstract

The invention discloses a rotary overhead conductor opening device, and aims to provide the rotary overhead conductor opening device which can open two overhead conductors reliably, provides a sufficient operation space for vertical rod operation, and is convenient to operate. The device comprises a vertical pipe, a strip-shaped hole formed in the pipe wall of the vertical pipe and extending in anaxial direction of the vertical pipe, guide rings connected with the vertical pipe through connecting pieces and positioned above the vertical pipe, a sliding sleeve which slides along the vertical pipe, a sliding sleeve locking bolt arranged on the sliding sleeve, a pull rod arranged on the inner side surface of the sliding sleeve, two supporting rods distributed on the two opposite sides of thevertical pipe, and self-adaptive wire fixing devices arranged on the supporting rods in a one-to-one correspondence mode. The upper ends of the supporting rods are hinged to the upper end of the vertical pipe; the supporting rods are connected with the sliding sleeve through connecting rods; and one end of each connecting rod is hinged to the middle of each supporting rod, and the other end of each connecting rod is hinged to the sliding sleeve.

Description

technical field [0001] The invention relates to an electric power construction tool, in particular to a rotating overhead wire stretching device. Background technique [0002] At present, when a new high-voltage pole needs to be erected on a certain section of the high-voltage line, two parallel wires need to be pulled apart to increase the distance between the wires to provide enough work space for the pole operation and ensure that the operation Safety. At present, there are several ways to open the two wires: [0003] First, use two electrified trolleys to carry out operations, and the electrified trolley stops at the two wires, and the construction personnel pull the conductors apart through the electrified trolley. This operation method requires the cooperation of the electrified trolley and several construction personnel, and the operation is inconvenient; [0004] Its two, tie up insulating working rope on two conductors, and two construction workers pull conductors...

AI Technical Summary

Problems solved by technology

[0003] First, use two electrified trolleys to carry out operations, and the electrified trolley stops at the two wires, and the construction personnel pull the conductors apart through the electrified trolley. This operation method requires the cooperation of the electrified trolley and some construction personnel, and the operation is inconvenient;

[0004] Its two, tie the insulating working rope on the two wires, and two construction workers pull the wires apart on the ground. This operation method pulls the overhead wires apart by manpower, and there is a big potential safety hazard.

[0005] Third, after the two wires are pulled apart, they are respectively connected to the insulating rod through the binding rope, so that the two wires are stretched apart. The connection between the binding rope and the support rod often requires several personnel to work together to stretch and position the wires. , and there is a greater security risk
