Disclosure of Invention

The invention aims to solve the technical problem that the prior overhead pole climbing operation for replacing an insulator with a wire dismounting insulator in the power line in the background art wastes time and labor and has potential safety hazards, and provides a tool for dismounting a jumper pole, which can quickly finish the wire dismounting operation, saves time and labor and can ensure the operation safety of workers.

The invention can solve the problems by the following technical scheme: the crossing rod wire stripper tool comprises a hollow connecting circular tube and a left wire clamp and a right wire clamp, wherein openings at the outer ends of the left wire clamp and the right wire clamp are connected through bolts; a bearing pressing bar is fixed between the clamp bodies at two side lines of the wire clamp; the nuts connected at the inner end heads of the two wire clamps and the nuts of the corresponding angle supports are respectively connected into a whole through bolts and one end threads of the connecting bolts; the nut end of the bolt is fixedly connected with the left end of the connecting circular tube; a sleeve of a ratchet wrench is arranged between the connecting bolt and the connecting circular tube; the outer ends of the left and right angle support angles are respectively fixedly connected through angle support bolts.

Compared with the background technology, the invention has the following beneficial effects: after the crossing rod wire disassembling tool is used, the wire disassembling work can be rapidly completed by one person, the efficiency is high, the time and the labor are saved, the time is saved for 36 minutes on average, the operation safety of workers can be guaranteed, a mechanical power source is provided by a ratchet wrench, and the task of separating the crossing rod wire from the insulator is easily completed.

FIG. 1 is a schematic structural diagram of the present invention.

In the figure: 1-wire clamp; 2-bearing pressure bar; 3-angle support; 4-a bolt; 5-connecting a circular tube; 6-ratchet wrench; 7-connecting bolts; 8-angle support bolt.

The specific implementation mode is as follows:

the invention will be further explained below with reference to the accompanying drawings:

as shown in the attached drawing 1, the spanning rod wire stripper tool comprises a ratchet wrench 6 and a left wire clamp 1 and a right wire clamp 1, wherein the left wire clamp 1 and the right wire clamp 1 are duckbilled wire clamps; the openings at the outer ends of the left and right duckbill wire clamps are connected by bolts; bolt holes are formed in the wire clamp bodies on the two sides of the duckbilled wire clamp, a bearing pressure lever 2 is fixed between the wire clamps on the two sides of the duckbilled wire clamp through bolts in the bolt holes, and the bearing pressure lever is used for propping an inserted lead to fix the lead and protecting the lead from being damaged; nuts at the inner end heads of the left and right duckbilled wire clamps and nuts of the corresponding angle supports 3 are respectively connected into a whole through a bolt 4 and one end of a connecting bolt 7 in a threaded manner; namely, the nut at the inner end of the left duckbilled wire clamp and the nut of the corresponding left angle support 3 are respectively connected into a whole through one end of the bolt 4 by screw threads; the nut at the inner end of the right duckbilled wire clamp and the nut of the corresponding right angle support 3 are respectively connected into a whole through one end of a connecting bolt 7; the angle support 3 comprises two support rods and a nut connected between the two support rods; one end of each support rod is fixedly connected with the corresponding end of the corresponding support rod through a nut to form a triangular bracket; the other ends corresponding to the left and right angle braces 3 are fixedly connected through an angle brace bolt 8; the nut end of the bolt 4 is fixedly connected to the left end face of the hollow connecting circular tube 5; the nut end of the connecting bolt 7 is inserted into the inner cavity of the right end of the sleeve of the ratchet wrench 6, so that after the tool is assembled, the ratchet wrench 6 pushes and pulls the sleeve to rotate, and the connecting bolt 7 is screwed out or in; the left end sleeve of the ratchet wrench 6 is inserted into the inner cavity at the right end of the hollow connecting circular tube 5, and the purpose is to support and fix the ratchet wrench 6. The left end of the sleeve of the ratchet wrench 6 is a phi 19 sleeve; the right end is a phi 24 sleeve.

The spanning rod wire breaker tool is used as follows:

1. and opening a bolt of the duckbilled wire clamp on the left side, clamping the left side line of the rhombic conductor into the wire clamp, and enabling the bearing pressing rod 2 to support the conductor to be fixed.

2. And adjusting the bolts 4 to ensure that the length between the force bearing pressing rods on the two sides of the tool is consistent with the length between the diamond-shaped leads.
