in the process of installing the wire anti-abrasion wire crossing frame device for paying off a distribution network on a wire of an original line, after a transverse hanging rod is hung on hanging holes of two side plates of a corresponding roller bracket, a vertical stop rod is moved downwards until an upper limiting block is abutted against the upper end of a vertical guide sleeve, at the moment, the vertical stop rod blocks the transverse hanging rod, so that the transverse hanging rod is kept on the hanging holes of the side plates, and a balance weight is hung on the roller bracket through the hanging rod; after the anti-abrasion wire crossing frame device for the wires for paying off the distribution network is installed on the wires of the original circuit, an operator enables the wires of the original circuit to be positioned between two lower paying-off ropes, the limiting rods are distributed up and down, the fuze ropes are connected to the lower ends of the limiting rods, the lower ends of the lower paying-off ropes are hung on the ground, the balance weight connecting ropes are hung on the ground, and the lower ends of the fuze ropes are close to or hung on the ground;
after the paying-off is finished, an operator pulls the counterweight connecting rope on the ground surface, and pulls the limiting rod downwards through the fuze rope, so that the limiting rod is separated from the splicing sleeve; then, an operator gradually releases the counterweight connecting rope on the ground surface, the two counterweight pieces are lowered to the ground, then the operator pulls one of the counterweight connecting ropes on the ground surface to enable the distribution network paying-off wire anti-abrasion wire crossing frame device to rotate on the wires of the original line, the movable frame and the wire crossing frame are located below the wires of the original line, at the moment, the distribution network paying-off wire anti-abrasion wire crossing frame device is hung on the wires of the original line through the transverse hanging rod, one of the counterweight connecting ropes bypasses the wires of the original line, and the unlocking pull wire in the paying-off box falls off from the paying-off box under the action of self weight; then, an operator pulls the vertical stop lever downwards on the ground surface through the unlocking pull wire until the lower limiting block abuts against the lower end of the vertical guide sleeve, and at the moment, the vertical stop lever moves to the position below the hanging hole; then the operator releases gradually at the earth's surface and walks around this root of the wire of former circuit and puts the rope, this in-process, the removal frame with the line frame more will move down under the dead weight effect (the horizontal peg of pendant will up move along the hanging hole to shift out the hanging hole through the access & exit), thereby will whole join in marriage net for the unwrapping wire abrasionproof damage line frame device of crossing and transfer to ground, the realization will join in marriage net for the unwrapping wire abrasionproof damage line frame device of crossing and take off on the wire of former circuit at the earth's surface, need not to go up the shaft tower operation, its convenient operation is swift.
Further, as shown in fig. 4, the hanging piece locking device comprises two vertical limiting sleeves 6.7, the two vertical limiting sleeves are correspondingly arranged on the lower portions of the outer side surfaces of the two side plates of the roller wheel support one by one, the vertical limiting sleeves are located below the hanging holes, and when the upper limiting block abuts against the upper end of the vertical guide sleeve, the lower end of the vertical stop rod is inserted into the vertical limiting sleeves.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, alterations and equivalents of the above embodiments according to the technical spirit of the present invention are still within the protection scope of the technical solution of the present invention.
