Double-bundled-conductor hoisting frame with idler wheels

Abstract

The invention discloses a double-bundled-conductor hoisting frame with idler wheels and relates to the technical field of electric power circuit construction. The double-bundled-conductor hoisting frame comprises a hoisting frame body, hanging rings or hanging hooks are arranged on the hoisting frame body, the two idler wheels are arranged on the hoisting frame body, the two idler wheels are arranged in an up-and-down mode or a left-and-right mode, and the axes of the two idler wheels are both perpendicular to conductors. The pair of idler wheels which can revolve around the axes of the idler wheels are arranged on the double-bundled-conductor hoisting frame, therefore, the bundled conductors can slide along with the rotation of the idler wheels when the bundled conductors are placed on the idler wheels to be hoisted, the hard friction between an existing bundled conductor lifting machine and the bundled conductors is avoided, abrasion and breakage to conductor bodies of the bundled conductors in the hoisting process are reduced to the maximum degree, integrity of the conductors is powerfully protected, the work efficiency of electric power circuit remodeling is greatly improved, and the workload of secondary maintenance caused by damage to the conductors is avoided.

Description

technical field [0001] The invention relates to the technical field of power line construction. Background technique [0002] In recent years, due to the rapid development of social economy, new roads, railways, power lines, etc. are also under construction at high speed in an orderly manner, and old lines spanning to-be-built and built roads, railways, power lines, etc. are also increasing day by day. The line has also brought about problems that must be changed, so the reconstruction and elevation of the line are also being carried out intensively. Many lines erected in the air are facing the construction of other new facilities, which affects the construction and have to be elevated.

AI Technical Summary

Problems solved by technology

In the past, the double-split conductor wire lifter for 220KV lines was prone to displacement of the conductor in the lifter during the process of lifting the conductor, resulting in conductor wear and strand breakage, etc.

Especially when the old-fashioned wire lifter is used to lift higher wires, it may cause serious wear and tear of the wires, strand breakage, etc., which is dangerous to the wires, and it takes time to repair. The pole is far away, people at high altitude cannot reach the position, and the tackle cannot be installed correctly and conveniently
