Abstract
The utility model relates to an insulative double-hook wire grip with a treble block, which belongs to the technical field of the design and manufacture of wire grips. The wire grip consists of an outer insulative clamp plate and an inner insulative clamp plate. A treble block is arranged between the clamp plates; and the inner insulative clamp plate and the outer insulative clamp are connected by coupling bolts and a block shaft. The upper part and the lower part of the inner insulative clamp plate are respectively provided with a lifting hook. When in use, a treble block is firstly fixed on the cross arm of a pole, an insulative rope and the treble block of the wire grip are used to form a pulley block. The upper lifting hook and the lower lifting hook respectively hook two conductors of a stranded conductor. An operator on the ground pulls a rope, the upper lifting hook and the lower lifting hook simultaneously lift the two conductors of the stranded conductor through the transmission of the pulley block, and then the operation of changing an insulator chain is carried out, thereby increasing the work efficiency and extending the application range. The wire grip has simple structure and reasonable design and is an ideal wire grip which solves the actual problem that the existing wire grip is fit for the change of the insulator chain of single conductors only.
Description
Technical field
The utility model belongs to the design and the manufacturing technology field of line lifter.
Background technology
The charged for replacement insulator chain is a groundwork of hot line work, can reduce the power off time and the number of times of circuit as much as possible, to improve the continuity and the reliability of power supply.Now change employed line lifter in the insulator chain operation, just a three-wheel list hook line lifter is fixed on a three-fold block on the cross-arm of shaft tower during operation, three-wheel list hook line lifter is hung on the hook below the three-fold block again, and line lifter list hook is lived lead.Operating personal stands in ground, and the pulling rope is sling lead by pulley, changes insulator chain then.But this line lifter only is suitable for the single line insulator chain and changes owing to have only a hook.For existing most of multiple wire line that adopts, the charged for replacement insulator chain is inapplicable.
Summary of the invention
The purpose of this utility model provides a kind of line lifter that is applicable to that single, multiple wire insulation is changed, to solve the practical problems that existing product exists.
Structure of the present utility model is as shown in drawings: in the both sides, top of line lifter one outer layer insulation clamping plate are arranged respectively, have two primary insulation clamping plate between outer cleat insulator.Between cleat insulator, have three insulating blocks.Central part at cleat insulator all has through hole, has sheave shaft in the through hole.Constitute three-fold block by sheave shaft and three pulleys.On the primary insulation clamping plate, have fastening bolt.Suit one metal sleeve on fastening bolt.Metal sleeve places between two primary insulation clamping plate, works the primary insulation clamping plate effect of supporting.Have lancet on interior laminated plank top, the bottom has lancet down.
Using method of the present utility model is: a three-fold block is fixed on the cross-arm of shaft tower, utilizes insulation rope and this product three-fold block to form assembly pulley.Last lancet and following lancet are hooked on respectively on two leads of multiple lead, and operating personal spurs rope on ground then, by the assembly pulley conduction lead is sling.Carry out the replacing of insulator chain again.Because this product has lancet up and down, both has been applicable to the single conductor operation, is applicable to multiple lead operation again.Can mention two leads simultaneously, improve work efficiency.Solved the problem that existing product exists.Be a kind of desirable line lifter, it is simple in structure, and is reasonable in design.
