Novel overhead cable hanging device

Abstract

The invention particularly discloses a novel overhead cable hanging device which comprises a steel strand hanging and clamping part arranged at the upper end, a cable supporting part arranged at the lower end, a pair of connecting arms arranged between the steel strand hanging and clamping part and the cable supporting part, an opening and closing connecting part arranged at the ends, close to thecable supporting part, of the pair of connecting arms, and a locking piece. The steel strand hanging and clamping part comprises a pivoting part, extending parts extending downwards along the two sides of the pivoting part, and arc-shaped wire wrapping grooves transversely formed in the opposite inner sides of the two extending parts respectively; the opening and closing connecting part comprisesa first connecting part and a second connecting part, and the locking piece penetrates through and is locked in a shaft hole through which the first connecting part and the second connecting part arecommunicated with each other; and the two arc-shaped wire wrapping grooves are locked by the locking piece and then are encircled to form an approximately annular steel strand wrapping and clamping cavity. Transverse displacement of the cable hanging device can be effectively avoided, meanwhile, the cable hanging device is stably hung on a steel strand and is not prone to falling off, and the structure is compact and small.

Description

technical field [0001] The invention relates to the technical field of electric wire hanging appliances, in particular to a novel overhead cable hanging device. Background technique [0002] When erecting the cable, due to the large span between the cable support frames, the cable will sag or even break under the action of tension and self-weight. Traditionally, a steel strand is erected in the air, and the wire is wound or hooked, etc. Hang the cable on the steel strand. The traditional hook is a piece of metal wire folded into a V shape in the middle, and the two ends are folded into a hook shape. The traditional hook is easy to fall off from the steel strand during the hooking process; at the same time, because the operator works in the air, the dropped hook often falls to the ground, which is not easy to pick up; and the traditional hook will swing longitudinally with the wind.

AI Technical Summary

Problems solved by technology

The traditional hook is easy to fall off from the steel strand during the hooking process; at the same time, because the operator is suspended in the air, the dropped hook will often fall to the ground, which is not easy to pick up; and the traditional hook will swing longitudinally with the wind

[0003] In order to reduce the vertical swing of the hook with the wind, the hook is changed from a V shape to a W shape, but this structure requires the hook to be hung on the cable first, and then the two hooks are moved to deform the wire and put the cable into the W-shaped hook on the two V-shaped corners of the body, and finally hang the two hook reset hooks on the steel strands, making it extremely inconvenient to work at heights

[0004] The traditional V-shaped or W-shaped hooks are made by bending metal wires, and the contact surface with the cables is small, which is easy to damage the insulation layer of the cables

In addition, in the case of strong wind, the traditional hook will bear a large shear force, causing the hook to break

[0005] In order to improve the above-mentioned defects of the traditional hook, the company has submitted several patent applications for the cable hanging device, which can effectively solve the problem that the traditional hook is easy to damage the cable insulation layer and it is easy to withstand a large shearing force when the wind is strong. broken problem

However, the problem of lateral displacement of the hanging device along the steel strand cannot be overcome, which in turn affects the stability of the hanging device, and there is also the possibility of loosening or falling off
