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

Embodiment 2

[0015] Example 2 as figure 2 A double-split wire lifting frame with rollers is shown, including a lifting frame body, which is provided with a hanging ring or a hook 4, and two rollers 1, which are arranged left and right, and the two rollers 1 The axes are perpendicular to the wire. The body structure of the lifting frame is an isosceles triangle frame, and two bottom corners of the isosceles triangle frame are respectively provided with a U-shaped groove 3 in the outer sides of the two base angles. Or the hook 4 is the isosceles triangle frame itself. The roller 1 is a grooved wheel. The material of the roller 1 is aluminum alloy. During use, the left and right wires are carried on the left and right rollers 1 respectively, and the purpose of lifting the wires is achieved by lifting the hanging ring or the hook 4 .

[0016] The beneficial effect produced by adopting the above-mentioned technical scheme is that: the double-split wire lifting frame with rollers makes the ...

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. Transformation, especially for the upgrade of double-split conductors for 220KV lines. 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 str...
