(2) firstly, two operators are needed, wherein the two operators are respectively arranged on a left iron tower and a right iron tower, the operator of the right iron tower holds the cut-off device, then the operator of the right iron tower hangs the cut-off device on a cable after reaching the top end of the iron tower, and then the split traction ring on the main body fixing seat is connected with a grinding rope of a winch of the right iron tower; (3) then operating a remote controller, starting a jacking motor in the walking driving assembly, driving a jacking lead screw to rotate through the jacking motor, driving a middle lower guide wheel to move upwards through a jacking sliding seat, clamping a cable through a left upper guide wheel, a right upper guide wheel and a middle lower guide wheel, so as to tightly press the cable clamped in the jacking lead screw to achieve friction adhesive force in walking action, then starting a walking driving gear, driving the middle lower guide wheel to rotate through the walking driving motor to realize walking movement of a main body fixing seat on the cable, walking the main body fixing seat and a split fixing seat to a left iron tower, and connecting a twisted rope of a left iron tower winch with a main body traction rope on the main body fixing seat by an operator of the left iron tower;
(3) the remote controller is operated, the walking driving motor rotates reversely, so that the main body fixing seat and the split fixing seat walk towards the right side and walk to a position needing to be started;
(4) operating the remote controller, starting a main body meshing motor in the main body meshing assembly, and driving a main body meshing lead screw to rotate through the main body meshing motor so as to drive main body meshing teeth to slide towards the main body fixed meshing teeth direction to realize cable meshing;
(5) operating a remote controller, starting a split meshing motor in the split meshing assembly, and driving a split meshing lead screw to rotate through the split meshing motor so as to drive split meshing teeth to slide towards the direction of split fixed meshing teeth to realize cable meshing;
(6) the remote controller is operated, a retracting motor in the retracting assembly works, a retracting lead screw rotates, the main body fixing seat and the split fixing seat are close to each other, meanwhile, the main body traction ring and the split traction ring are pulled through a grinding rope of a left iron tower winch and a grinding rope of a right iron tower winch, the split fixing seat and the main body fixing seat are also close to each other, finally, occluded cables are close to each other, and therefore the original tension of a broken line is eliminated;
(7) operating the remote controller, opening a shearing motor in the cutting assembly, driving the force boosting device to eject the shearing moving blade out through the shearing motor, cutting, and further shearing the cable;
(8) and operating the remote controller, enabling a winding and unwinding motor in the winding and unwinding assembly to work, reversely rotating a winding and unwinding lead screw, keeping the main body fixing seat and the split fixing seat away from each other until the winding and unwinding lead screw is separated from the winding and unwinding screw, separating a lead on the split fixing seat from a separation socket on the main body fixing seat, finally respectively releasing a grinding rope of the left iron tower winch and a grinding rope of the right iron tower winch, and slowly putting down two ends of a disconnected cable.
2. The method according to claim 1, wherein the main body fixing seat in step (1) is provided with a detachment early warning device, the detachment early warning device is connected with the detachment sensor through a remote control receiver, and the detachment sensor gives an alarm through the detachment early warning device after detachment.
