Abstract

The utility model relates to a special tool for line lifting in the high-voltage power transmission line overhead earth wire construction of a power system, in particular to an overhead earth wire lifting device. The lifting device comprises a lifting device, a lifting hook, a steel wire rope and a spanner, wherein, the lifting device is connected with the lifting hook by the steel wire rope arranged on a bobbin winder pulley. In the utility model, because of the structure, constructors do not need to use pickaback when they conduct high-voltage power transmission line overhead earth wire construction and can independently complete the line lifting operation, which prevents the injury to limbs during the construction, reduces the labor intensity and relieves the unsafe hidden danger. The special tool has the advantages of simple and reasonable structure, safety and reliability, high working efficiency, etc.

Description

The overhead ground wire rope hoister

Technical field

The utility model relates to the specific purpose tool that line is carried in a kind of electric power system high voltage circuit overhead ground wire construction, a kind of specifically overhead ground wire rope hoister.

Background technology

When the operation of electric power system field construction, particularly when the high voltage circuit overhead ground wire was constructed, the workmen was for the overhead ground wire of slinging at present, and the line method of carrying commonly used still adopts artificial method pickaback, the instrument of neither one special use.There are many shortcoming and defect in the heavy construction method of this tradition, and be in particular in: 1. owing to be work high above the ground, overhead ground wire weight is very big, and ground wire produces mobile sometimes, so adopt the damage that brings limbs pickaback through regular meeting to the workmen; 2. need double coordinative operation when above-mentioned construction operation, labour intensity is big, has hidden danger.

Summary of the invention

The purpose of this utility model be to provide a kind of simple and reasonable, safe and reliable, be fit to that one-man service, labour intensity are low, the overhead ground wire rope hoister of high efficiency.

The purpose of this utility model is achieved in that this rope hoister comprises rope hoister main body, main hook part, steel wire rope, spanner, and wherein the rope hoister main body is connected with main hook part by the steel wire rope that is provided with on its reel.

Described rope hoister main body is made of reel framework and messenger wire seat two parts, its reel framework is arranged on the messenger wire seat, and can rotate along the connection bearing pin on it, the reel framework is provided with winding wheel shaft, reel is arranged in the reel framework, on the reel, an end of a side of reel framework, reel be provided with by have a spring spacing draw for a short time spacing flywheel and with spanner on the corresponding wrench of plate mouth; What described messenger wire seat adopted is " recessed " word shape structure, has recess and through wires hole above, and a side of recess and through wires hole has jackscrew.

Described main hook part is made of pedestal, axle, pulley, suspension hook, latch hook nut, and its axle that is provided with pulley is arranged on the pedestal, and suspension hook is arranged on the top of pedestal by the latch hook nut.

The utility model is owing to adopt said structure to make the workmen when carrying out the construction of high voltage circuit overhead ground wire and propose the line operation, do not need to use pickaback, single independence just can be finished and propose the line operation, avoided in work progress damage to limbs, alleviate labour intensity, eliminated unsafe hidden danger.Have advantages such as simple and reasonable, safe and reliable, operating efficiency height.

Embodiment

This rope hoister comprises rope hoister main body 1, main hook part 2, steel wire rope 3, spanner 21, and wherein rope hoister main body 1 is connected with main hook part 2 by the steel wire rope 3 that is provided with on its reel 8.

Described rope hoister main body 1 is made of reel framework 4 and messenger wire seat 5 two parts, its reel framework 4 is arranged on the messenger wire seat 5, and can rotate along the connection bearing pin on it 6, reel framework 4 is provided with winding wheel shaft 7, reel 8 is arranged in the reel framework 4, on the reel 7, an end of a side of reel framework 4, reel 7 be provided with by have a spring spacing draw for a short time 10 spacing flywheels 9 and with the corresponding wrench 11 of plate mouth on the spanner 4; What described messenger wire seat 5 adopted is " recessed " word shape structure, has recess 12 and through wires hole 13 above, and a side of recess 12 and through wires hole 13 has jackscrew 14,15.

Described main hook part 2 is made of pedestal 16, axle 17, pulley 18, suspension hook 19, latch hook nut 20, and its axle 17 that is provided with pulley 18 is arranged on the pedestal 16, and suspension hook 19 is arranged on the top of pedestal 16 by latch hook nut 20.

The course of work

During use, messenger wire seat 5 is snapped on the stringing cross-arm (angle bar), fixing by top jackscrew 14, put down main hook part 2, suspension hook 19 is hooked on the overhead ground wire, adopt wrench 4 clockwise directions rotations to hang tight then, make overhead ground wire break away from the wire clamp position, draw 10 the stuck flywheel 9 of auto lock prevented its reverse for a short time on the reel framework 4.At this moment the workmen just can place or change coaster or wire clamp operation.
