The tool of the utility model introduces a pulley block to combine with the clamping apparatus, thereby making the phase insulator chain in the double/ multi-circuit with inadequate safe distance realize ground potential replacement. The tool of the utility model features convenient and flexible operation, low labor intensity, high working efficiency, and reliable and secure operation, and is capable of creating remarkable economic and social benefits.

Description

The instrument of phase insulator string in many times towers of charged for replacement circuit
Technical field
The utility model relates to a kind of two instrument of phase insulator string in the phase replacing insulator string instrument, particularly many times towers of a kind of charged for replacement circuit that returns in the towers.
Background technology
Because the requisition of circuit corridor is more and more difficult, power transmission sequence adopts double loop or multi-circuits transmission lines on single tower shaft tower in a large number, adopt vertical arrangement such as 110KV circuit double loop tangent tower wire, middle phase cross-arm is generally 3.5 meters with upper phase cross-arm, behind deduction insulator string length and the middle mutually cross-arm height, middle phase cross-arm and upper conductor distance only have about 1.2 meters, phase insulator during if Live line maintenance method is changed routinely, personnel need enter the operation of middle phase cross arm end, 1.2 safety requirements can't be satisfied in the gap of rice, can only power failure operation, this has reduced power supply reliability simultaneously just so that amount of power supply is subjected to a large amount of losses.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and provides a kind of applicable to phase insulator string instrument in the two many times towers of charged for replacement circuit that return phase insulator in towers or the many times towers of earth potential live replacing circuit.
The instrument of phase insulator string in many times towers of a kind of charged for replacement circuit, its structural feature is: include the pulley jig, two bar insulation ropes, described pulley jig includes jig and two s' running block, described jig is wing-shaped structure, be provided with the open seam of the snapped in cross-arm of linking up the jig front-back in the middle part of wing-shaped structure, reach the square groove vertical with open seam that extends along two flank directions of wing-shaped structure, the notch of this square groove is positioned at the jig lower surface, lower surface at jig two flanks is respectively arranged with the fixed pulley group, each fixed pulley group has more than one fixed pulley, be provided with the hangers be used to the jig of slinging in the upper end of jig, the fixed pulley number of the fixed pulley group on the pulley number on each running block and jig one flank is complementary, and is provided with the hook be used to the wire of slinging in the bottom of each running block.
The two instruments that return phase insulator string in the tower of the charged for replacement circuit of this structure, assemble various power tools on ground by the staff, with two bar insulation ropes and two running blocks, form a cover assembly pulley with the fixed pulley group on jig two flanks, the length of insulating cord wherein should fall to ground to make things convenient for the ground staff to operate after walking around movable pulley and fixed pulley, then the staff climbs middle cross-arm root and with action bars jig is installed on the terminal insulator string suspension point of middle cross-arm place, jig middle aperture slots and square groove closely are fixed on the cross-arm, and two movable pulleys hook is hung wire; The ground staff tightens up the tail rope of two assembly pulley insulating cords, with on insulator load transfer to the two cover assembly pulley, thereby can realize replacing insulator under electrified.
Be provided with for the hangers that hangs the starter pulley group at running block.
Also be provided with two fixed pulley on the jig between the two fixed pulley groups of jig, two fixed pulleys are divided on the flank of open seam both sides.
Set up a fixed pulley between two fixed pulley groups of jig, changing the porcelain insulator period of the day from 11 p.m. to 1 a.m, because porcelain bottle insulators weight is very heavy, therefore available rope is sling porcelain vase by this fixed pulley, plays the effect of weight reduction.
In sum, the utility model following advantage compared to existing technology:
The two instruments that return phase insulator string in the tower of charged for replacement circuit of the present utility model, in the middle of assembly pulley being incorporated into jig, be combined with jig, and so that for inadequate two of safe distance return or many times tower circuits in the phase insulator string realize earth potential replacement, it has convenient and flexible operation, labour intensity is low, operating efficiency is high, and job safety is reliable, can create comparatively considerable economic benefit and social benefit.
The two instruments that return phase insulator string in the tower of charged for replacement circuit of the present utility model are the ingenious combinations of jig and pulley, have realized the indirect operation installation, it transfers to ground to the stringing operation from tower, greatly reduce the gap operating workload, improved operating efficiency, reduced labour intensity;
