the disassembling and assembling mechanism comprises a connecting sleeve, a screw rod, a threaded sleeve, a clamping piece and a moving piece, the screw rod is fixedly arranged on the connecting sleeve, and the clamping piece and the moving piece are respectively arranged on the screw rod through the threaded sleeve; one side of the connecting sleeve is provided with an L-shaped clamping groove, the other side of the connecting sleeve is provided with a positioning hole, the upper end of the connecting rod is provided with a through hole, a positioning pin is arranged in the through hole, and the connecting rod is clamped in the connecting sleeve and is fixed through the positioning pin; the clamping piece comprises a bottom plate, a bayonet used for clamping the insulator string bowl head is arranged on the lower side of the bottom plate, a limiting groove used for preventing the moving piece from separating is arranged on the upper side of the bottom plate, positioning grooves are arranged on the left side and the right side of the bottom plate, and positioning plates are arranged on the lower portions of the two positioning grooves; the movable part comprises an inverted U-shaped rod and two hanging rods arranged on the upper part of the inverted U-shaped rod, two sides of the inverted U-shaped rod are respectively positioned in the two positioning grooves, the upper side of the inverted U-shaped rod is positioned in the limiting groove, a strip hole is formed in the front side of the limiting groove, and the two hanging rods extend out of the strip hole; the two hanging rods are vertically arranged, and the distance between the two hanging rods is larger than the thickness of the R-shaped pin;
the dismounting method of the insulator string R-type pin ground potential steering dismounting device comprises the following steps:
(1) The ground potential operator adjusts the relative angle of the first connecting frame and the second connecting frame according to the position of the R-shaped pin of the insulator string, so that the first connecting frame and the second connecting frame are in horizontal connection or vertical connection and are fixed through bolts and nuts;
(2) An operator holds the insulating rod by hand, clamps the clamping member on the insulator string bowl head and enables the hanging nose of the R-shaped pin to be hung on the hanging rod at the lower side of the moving member;
(3) The crank at the end part of the insulating rod is rotated to enable the transmission shaft in the insulating rod to generate forward rotation or reverse rotation driving force, and the movable part of the disassembling and assembling mechanism moves up or down through the transmission of the steering rotating mechanism, so that the R-shaped pin is pulled out or pressed into the socket head, and the disassembling or assembling of the R-shaped pin is realized;
in the step (1), when the V-shaped insulator string is dismounted, repaired or replaced, a ground potential operator stands on the cross arm on the upper side of the insulator string, adjusts the first connecting frame and the second connecting frame to be vertical, and then carries out dismounting; when I shape insulator chain carries out dismouting maintenance or change, the ground potential operation personnel stand in insulator chain side to adjust first link and second link to the horizontality, carry out the dismouting.
