Link plate top is parallel with mobile jam plate.
Can make the jig structure more firm like this, and can be in the cross-arm end stable pinning jig.
The connecting portion of link plate and mobile jam plate lay respectively at the two sides on link plate top.
In general, the insulator string of cross-arm T type hanging point is single string, when operation, needs as far as possible the stringing device of both sides away from insulator string, and when mobile jam plate was positioned at close cross-arm one side of link plate, connecting portion preferably was positioned at the opposite side of link plate when therefore operating.
The integrated structure in the top of link plate and bottom.
Can turn parts into the whole like this, simplify tool construction, reduce the instrument amount of parts, operating efficiency is provided, this moment, the link plate bottom was preferably a kind of annulus structure.
The upper and lower of link plate is a kind of " ┓ " in the plane.
Like this, when mounted, connecting portion can be more forward, and is in the same plane as much as possible with insulator string, is convenient to change operation.
The stringing device includes fixed pulley, movable pulley and metal hook, and each pulley all is equipped with metal hook, wherein the lead that is connected with suspension insulator to be replaced of the corresponding respectively connecting portion that hooks link plate of the metal hook that is connected with movable pulley of fixed pulley.
During use, stay cord one end by the ground handling personnel operation, can further be simplified the working procedure that is positioned at staff on the cross-arm like this, improve operating efficiency.
Operational method of the present invention can further be specially:
The link of insulating bar is a kind of snail hook.
The snail hook shape is shape in the shape of a spiral, and an end is installed on the insulating bar, and the other end then at least one circle of spiral back is unsettled.During operation, free end is stretched into the operating portion of mobile jam plate, rotate insulating bar, make operating portion deeply along snail hook.
Because the operating space on the steel pipe pole is little, during the map function angle, personnel can't follow and shift one's position traditional insulating bar, thereby occur the unhook phenomenon easily, bring operational inconvenience, even cause safety problem in operating process.The used snail hook of the present invention has solved the problems referred to above, and it can hook jig to greatest extent, easily translation-angle and can not breaking off relations.
