Abstract
The utility model discloses an insulator replacement tool, which belongs to the overhead line mounting tool. The insulation replacement tool comprises a cross bar, one end of the cross bar is fixedly provided with a hanging hook, the other end of the cross bar is provided with a hanging rod, the depth of the groove of the hanging hook is less than the width of the angle bar of a cross arm; the width of the groove of the hanging hook is more than the thickness of the angle bar of the cross arm, a limit block is fixedly arranged on the hanging ring and below the cross bar, and the upper end of the hanging ring and the cross bar are both provided with a nut. When the utility model is used, the hanging hook can be clamped on the angle bar of the cross arm and can not fall off the cross arm, thereby making the operation secure. Moreover, a pulley I is suspended in the middle of the cross bar and is connected with a transmission rope, a pulley II is suspended on the hanging ring and is connected with a hoist rope, and the two ropes are suspended in different hanging points with no twisting. Therefore, the utility model has the advantages of safe use and simple operation.
Description
Technical field
The utility model belongs to overhead transmission line erecting tools field, is specifically related to a kind of insulator and changes instrument.
Background technology
A lot of insulators is arranged, owing to reasons such as aging and flashover need often maintenance and change insulator in transmission line.When changing insulator, need promote lead with the cucurbit rope, transmit the rope tool for transmitting.But there is not special-purpose insulator to change instrument at present, the hitch point of cucurbit rope and transmission rope is all on the cross-arm brace, there are following two problems in this: 1, cucurbit rope and transmit rope both hang on a suspension centre and often make that rope is intertwined is difficult to separate rope, troublesome poeration when work high above the ground; 2, fail safe is poor.
The utility model content
The technical problems to be solved in the utility model is that insulator transmits the restrict problem of easy winding, troublesome poeration, poor stability of rope and cucurbit when changing, and provides a kind of rope and cucurbit rope of transmitting to be difficult for winding, insulator replacing instrument simple to operate, safe in utilization.
The technical solution of the utility model realizes with following method:
A kind of insulator is changed instrument, comprises cross bar, and cross bar one end is suspension hook fixedly, and the cross bar other end is provided with suspension ring, and fixed limit piece on the suspension ring, guide vane end stop are positioned at the cross bar below, on suspension ring upper end, the cross bar nut is set.
The degree of depth of described suspension hook hook groove is less than the width of cross-arm angle steel; The width of suspension hook groove is greater than the thickness of cross-arm angle steel.
Fixed limit piece on the described suspension ring, guide vane end stop are positioned at the cross bar below, on suspension ring upper end, the cross bar nut are set.
Adopt insulator of the present utility model to change instrument, suspension hook is stuck on the angle steel of cross-arm, guarantees not break away from handling safety from cross-arm.The mid-mounting pulley I of cross bar, pulley I go up to connect and transmit rope, hang pulley II on the suspension ring, and pulley II goes up and connects the cucurbit rope, and two ropes hang on different suspension centres, can not twine between the two, and are safe in utilization, simple to operate.
