The utility model provides an electrified insulator chain lifting mechanism, includes the insulating rope of fixed pulley, movable pulley and winding movable pulley and fixed pulley, insulating wheel on fixed pulley and the movable pulley all disposes according to the two -stage quintuplet, the fixed pulley top is articulated to have the yoke plate to connect, and the yoke plate connects and links to each other with construction mounting hole on the cross arm through the round pin axle, the movable pulley bottom is articulated to have the lifting hook to connect, and the lifting hook connects and links to each other with the four -bundled conductor lifting hook through the round pin axle. The advantage is: can provide sufficient traction force, guarantee that four -bundled conductor's insulator chain is lax simultaneously, the change is more swift, by transferring to ground to the stringing operation from the tower, can reduce clearance operation work volume, has both improved the operating efficiency, can also reduce intensity of labour.
