Abstract
The invention discloses a lifter special for overhauling of a 220-kilvolt overhead ground wire of a power transmission line. The lifter comprises a balancing strut beam, wherein the balancing strut beam is a square shoulder type balancing strut beam; clamping apparatus is arranged on the lower part of the balancing strut beam; lifting rods are arranged at two ends of the balancing strut beam; and lifting hooks are arranged at the lower ends of the lifting rods. The lifter has a simple structure and good safety performance, is durable and tight in connection, is convenient to operate, shortens the working time by 50 percent, and can greatly improve the working efficiency.
Description
Technical field
The present invention relates to a kind of electric power facility apparatus for examination and repair, be specifically related to 220 kilovolts of lightning conducters of a kind of transmission line and overhaul special-purpose lifter.
Background technology
220 kilovolts of lightning conducter service kits that use at present are made up of truss structure and palm cucurbit two parts of angle steel processing.During use it is installed in the top of 220 kilovolts of goat's horn cross-arms,, on the palm cucurbit hitch point mounted thereto, promotes lightning conducter then and change the annex gold utensil with this job platform as the palm cucurbit.Mainly there is following deficiency in existing operation tool: (1) this instrument is made up of truss structure and palm cucurbit two parts of the processing of ∠ 50 * 5 angle steel, and the instrument total weight reaches 14 kilograms, and is very heavy, is not easy to use.(2) this instrument and goat's horn cross-arm connecting portion are insecure, lack bracing structure, therefore along the line direction poor stability, are prone to take place rollover and cause lightning conducter to come off, and its security performance has satisfied not the safety in production needs.Need disengaging section cross-arm member when (3) this instrument is installed, operation sequence is loaded down with trivial details, and using wastes time and energy, and changes 1 place's lightning conducter annex gold utensil and need use about 1 hour.
Summary of the invention
The objective of the invention is to overcome the problems referred to above that exist in the prior art, provide 220 kilovolts of lightning conducters of a kind of transmission line to overhaul special-purpose lifter.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is following:
220 kilovolts of lightning conducters of transmission line of the present invention overhaul special-purpose lifter; This lifter comprises the balance strutbeam, and described balance strutbeam is provided with jig for flat shoulder formula balance strutbeam in balance strutbeam bottom; Be provided with lifting arm at balance strutbeam two ends, 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, connects fasteningly, durable in use, and security performance is good; Easy to operate, the activity duration shortens half the, can reach to increase substantially operating efficiency; Material is light, and instrument weight is reduced to 5.1 kilograms; Reduce line maintenance operation interruption duration, improve the business economic benefit.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1,220 kilovolts of lightning conducters of transmission line of the present invention overhaul special-purpose lifter, and this lifter comprises balance strutbeam 1; Described balance strutbeam is flat shoulder formula balance strutbeam; 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; Lightning conducter 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 lightning conducter to correct position; Remove the lightning conducter annex gold utensil that needs replacing, and the gold utensil that more renews; Rotation adjustment handle makes lightning conducter return to original position; Removal tool finishes operation.
