Description
Technical field
The utility model belongs to the instrument of changing the two insulator strings of simply connected in a kind of 500kV overhead power line.
Background technology
At changing 500kV circuit simply connected two string suspension insulator operational method and power tool, present operational method and the power tool that adopts, adopt cross-arm jig vertical-lift lead to make the lax method of insulator string change single insulator string, two yoke plates deflection can occur after an insulator string is freed therein, thereby new insulator string can't be in place.Solving insulator string two yoke plate deflection problems needs other machining fixture to fix two yoke plates, but the cross-arm card that is used for connecting the jig of two yoke plates can not installed with having.Cause the complicated operation of changing the two string of straight line simply connected suspension insulator.
Summary of the invention
The purpose of this utility model is exactly to disclose a kind of instrument of changing the two string of straight line simply connected suspension insulator.
The technical scheme that realizes above-mentioned purpose is:
A kind of instrument of changing the two string of straight line simply connected suspension insulator by last card, following card, is installed adjustable insulation arm-tie, lifting screw mandrel formation between last card and following card.Key is to go up blocking forming V-shape body, and two ends have screw, and attachment screw is installed, two grooves about having along the centre position of the length direction of V-arrangement body, and the interior bottom face of every groove is the inclined-plane; The recessed card of following blocking camber, an attachment screw is installed in the left end perforate of the recessed card of arc, and right-hand member has the screw mandrel trepanning of encapsulation lifting screw mandrel.This attachment screw and screw mandrel trepanning are on orthogonal; At the left end attachment screw of last card be connected with lifting screw mandrel and insulation arm-tie in the screw mandrel trepanning of card right-hand member down.
During use, on block right groove inclined-plane and be stuck in suspension insulator by on iron tower cross-arm side two yoke plates, the right side screw is connected with two yoke plate preformed holes, the left side screw is connected with the arm-tie that insulate.Under block the groove pocket on the insulator string socket-clevis eye, screw is locked in downside yoke plate upper edge, screw mandrel is inserted in down card right side circular hole and locking, screw mandrel is connected with the insulation arm-tie, tightens up screw mandrel at downside, card is simultaneously stressed up and down, and insulator string is relaxed, the replacing insulator string.
Working forms in conjunction with the two insulator strings of strain insulator bent plate card commonly used is used on the vertical two strings of 500kV, develop the upper and lower card of two yoke plates, be connected up and down with screw mandrel, strain insulator mode straight line is used, bigeminy integrated circuit board (going up card) utilizes the middle screw mandrel trepanning and the skew back face of two yoke plates, as hard point; Under connect adjustable insulation arm-tie, the yoke plate card that dangles (down card) passes in the middle of socket-clevis eye and wire clamp link plate, is fixed on the yoke plate upper edge of dangling with lock pin, pocket is on the screw of socket-clevis eye in the middle of the jig: with the upside-down mounting of lifting screw mandrel on card down.Tighten up screw mandrel, the pulling force that insulator string bears is transferred on the complete load instrument, the damaged insulator string is freed the insulator string that more renews.Adopt the coaxial force way of insulator string, the pulling force that insulator string is born changes to be born by combination tool, makes insulator string lax transferring to promote yoke plate along the insulator string axis direction and make insulator string lax in traditional lead of lifting vertically.Make that the operation of changing insulator string is safe, simple.
