Abstract
The invention relates to a 220-kilovolt ground wire lifting device of a power transmission line. The lifting device comprises a balance strut-beam; a clamp apparatus is arranged at the lower portion of the balance strut-beam; lifting rods are arranged at two ends of the balance strut-beam; and lifting hooks are arranged at the lower ends of the lifting rods. According to the invention, the lifting device has a simple structure and a good safety performance as well as can be used conveniently; besides, one third of working time is shortened and working efficiency can be substantially improved.
Description
Technical field
The present invention relates to a kind of electric power facility apparatus for examination and repair, be specifically related to a kind of 220 kilovolts of ground wire raisers.
Background technology
Power industry is the basis of national economy, is the guarantee of electric equipment operate as normal.Along with the develop rapidly of Chinese national economy, the rapid raising of living standards of the people, electric power has become indispensable assistant in our life.At present, transmission line is being born the effect of contact tie and bridge as the main path of transferring electric power, its whether safe and reliable the stable of electric power system that directly affect.
For guaranteeing that transmission line normally moves, often need that 220 KV ground wires are connected gold utensil (be used for overhead ground wire is fixed on shaft tower, be made up of U type ring or right angle link plate and suspension clamp) and carry out upkeep operation.At present 220 KV ground wires connection gold utensil is overhauled and all adopt Lever Blocks to promote working system, this operational method is time-consuming, effort, and efficient is low, and operation inconvenience.Owing to need carry out work high above the ground for a long time, operating personnel's physical demands is very big, and repair quality is difficult to guarantee, very is unfavorable for safety in production and standardized work.
Summary of the invention
The objective of the invention is to overcome the problems referred to above that exist in the prior art, a kind of 220 kilovolts of ground wire raisers are provided.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is following:
220 kilovolts of ground wire raisers of the present invention, this lifter comprises the balance strutbeam, and described balance strutbeam is a few font balance strutbeams, is provided with jig in balance strutbeam bottom, is provided with lifting arm at balance strutbeam two ends, and the lifting arm lower end is provided with suspension hook.
Described lifting arm is a leading screw.Also can adopt gear driven type.
On the lifting arm of the left and right sides, be provided with rotary handle among the present invention.
The present invention is simple in structure, carries convenient transportation, and on-the-spot applicability is good.Only 4.9 kilograms of lifter deadweights are convenient to that personnel carry and vehicle transport.Stability Analysis of Structures, safe and reliable.Lifter uses two-restriction filament bar to promote ground wire, has increased the safeguard protection of equipment, has improved the stability of lifter again.Activity duration is short, high efficiency.Every operation group only needs 3 people, reduces by 1 people than the Lever Blocks lift method, saves operating personnel 25%; Activity duration reduces 1/3rd than the Lever Blocks lift method, obviously increases work efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1,220 kilovolts of ground wires of the present invention overhaul special-purpose lifter, and this lifter comprises balance strutbeam 1; Described balance strutbeam is a few font balance strutbeams; Be provided with jig 2 in balance strutbeam 1 bottom, be provided with lifting arm 3 at balance strutbeam 1 two ends, described lifting arm is a leading screw.The lifting arm lower end is provided with suspension hook 5.On the lifting arm of the left and right sides, be provided with rotary handle 4.
Operation principle of the present invention is following: lifter of the present invention is fixed on the ground line bracket at goat's horn cross-arm top of 220kV circuit; Ground wire is put into the suspension hook 5 of two screw adjustable type structures arranged side by side; Tighten the hasp bolt, with instrument fixed card jail; Rotation adjustment handle promotes ground wire to correct position; Remove the ground wire annex gold utensil that needs replacing, and the gold utensil that more renews; Rotation adjustment handle makes ground wire return to original position; Removal tool finishes operation.
