Background Technology

[0002] Currently, the commonly used methods for fixing insulated guide wires in live-line power distribution work mainly include insulated fall arrest ropes and insulated hanging poles. Insulated fall arrest ropes are used to fix the insulated guide wires by binding or clamping, and then hooking them onto the main line. This process usually involves multiple steps: first, selecting suitable binding points, then using binding tape or clamps to fix the insulated guide wires. Using binding tape often requires certain skills and experience from the operator to ensure a secure fixation without damaging the insulated guide wire, making it inconvenient. Using clamps requires first opening the clamp's locking pins, then inserting the insulated guide wire, then closing the locking pins and clamping the wire, also inconvenient. Insulated hanging poles require first tightening the crossarm, then opening the spring clamps, then inserting and clamping the insulated guide wire. After the work is completed, removing the insulated fall arrest rope requires manually opening the safety buckle on the insulated hook, making it inconvenient. Summary of the Invention

[0039] Example 2

[0040] Based on Embodiment 1, the insulating rod 3 is threaded with a bolt. When the insulating lead wire for live-line operation is temporarily suspended, the stop rod 6 and the insulating rod 3 cooperate to cover the main lead wire. The bolt is rotated in the forward direction to make it press against the stop rod 6 to prevent the stop rod 6 from rotating on its own. When it is necessary to remove the temporary suspension device for the insulating lead wire for live-line operation, the bolt is rotated in the reverse direction to make it detach from the stop rod 6.

[0041] Example 3

[0042] The method for using temporary suspension devices for insulated lead wires in live-line power distribution work includes the following steps:

[0043] When the insulated lead wire is temporarily suspended during power outage operation of the distribution network, the insulating rod 3 is lifted so that the main line is in the first slot 8 until the main line pushes the sliding rod 9 into the insulating rod 3. The insulating rod 3 drives the linkage rod 19 to rotate around the second rotating shaft 24 in the forward direction through the through slot 25. The limiting slot 22 is disengaged from the limiting rod, and the second spiral steel 18 is compressed.

[0044] The first spiral steel 15 causes the stop rod 6 to rotate in the forward direction, and the main line enters the second slot 7. The stop rod 6 and the insulating rod 3 cooperate to cover the main line. The stop rod 6 pulls the slider 13 through the connecting line 4. The slider 13 drives the actuating element 2 to move. When the actuating element 2 is located on one side of the slot 12, the third spiral steel 20 pushes the retaining ring 21 to move. The retaining ring 21 drives the actuating element 2 to insert into the slot 12, preventing the actuating element 2 from being moved down due to misoperation. This completes the temporary suspension of the insulated lead wire temporary suspension device on the main line for the power distribution network non-stop operation.

[0045] The movable insulating guide wire allows the insulating guide wire clamp to engage with the insulating guide wire clamp 1, thus completing the temporary suspension of the insulating guide wire;

[0046] After the insulated lead wire is temporarily suspended for live power distribution work, remove the insulated lead wire clamp from the insulated lead wire clamp 1;

[0047] Pull the actuating element 2 to disengage it from the slot 12, compressing the third spiral steel 20. Then move the actuating element 2 away from the main line. The actuating element 2 drives the slider 13 to move. The slider 13 drives the stop rod 6 to rotate in the opposite direction through the connecting line 4 to reset it. When the stop rod 6 rotates in the opposite direction, the ramp 17 guides the limiting post 5 so that the limiting post 5 can drive the linkage rod 19 to rotate in the forward direction. Then the second spiral steel 18 pushes the linkage rod 19 to reset it. The limiting post 5 is inserted into the limiting groove 22. At the same time, the linkage rod 19 drives the sliding rod 9 to extend from the insulating rod 3 and penetrate into the first slot 8. The temporary suspension device of the insulating lead wire for the power distribution network without power interruption can be removed from the main line by lowering it.

[0048] The beneficial effects of this invention are that, compared with the prior art, when temporarily suspended on the main line, it can be fixed to the main line by simply lifting it up; the temporary suspension of the insulating guide wire can be completed by simply engaging the insulating guide wire clamp with the insulating guide wire clip; the insulating guide wire can be removed by simply pulling the insulating guide wire clamp laterally; and the temporary suspension device for the insulating guide wire can be removed from the main line by pulling the actuating component and moving it away from the main line. It is convenient to use.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention.
