[0001] The present invention relates to the technical field of transmission line equipment, and particularly relates to an overhead conductor repair device and a repair method thereof. Background Art

[0002] The safe operation of overhead transmission lines is directly related to the overall safe operation of the power grid. Overhead lines are directly exposed to the external environment. They not only have to bear mechanical loads and electrical loads during normal operation, but are also affected by natural environments and human factors. Therefore, overhead lines are prone to damage, and in severe cases, it may cause strand breaks or even wire breaks. This not only affects the safe operation of the line, but also seriously affects the lives and property safety of the general public, increasing the burden on the power transmission network. It is imperative to strengthen the protection work of power facilities.

[0003] In line maintenance work, locally stranded overhead lines can be put back into use after effective repair. Currently, the common repair method is that workers climb the tower and walk along the overhead line to the wire break point, and use materials such as preformed strands and aluminum single wires to manually wind the damaged part, which has a large labor intensity. Therefore, corresponding improvements are made to solve this problem. Summary of the Invention

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0032] Embodiment 1

[0033] Refer to Figures 1-9, An overhead wire repair device, including a first half-ring 1 and a second half-ring 3. There is a V-shaped notch 2 on the first half-ring 1, and the second half-ring 3 matches the shape of the notch 2. The front end of the first half-ring 1 is fixedly connected with a first half-ring track 4, and the front end of the second half-ring 3 is fixedly connected with a second half-ring track 5. The first half-ring track 4 and the second half-ring track 5 form a complete circle as a whole. There is a movable block 6 slidably connected in the first half-ring track 4. The front end of the movable block 6 is fixedly connected with a plurality of connecting columns 7, and the front ends of the plurality of connecting columns 7 are fixedly connected with the same handle 8. The front end of the handle 8 is rotatably connected with a winding drum 9, and a preformed wire 10 is wound on the winding drum 9. The rear end of the second half-ring 3 is fixedly connected with two sleeve rods 11 symmetrically distributed on both sides. Embedding grooves 12 are opened on the opposite sides of the two sleeve rods 11. A first spring 14 is fixedly connected in the embedding groove 12, and an inner rod 13 is fixedly connected to the outside of the first spring 14. A clamping portion 15 is arranged on the outside of the inner rod 13. The rear end of the first half-ring 1 is fixedly connected with two positioning columns 16 symmetrically distributed on both sides.

[0034] Further, the cross-section of the clamping portion 15 is crescent-shaped. That is, when the second half-ring 3 is clamped into the notch 2, the clamping portion 15 can make the clamping portion 15 contract into the embedding groove 12 along with the inner rod 13 through the action of its outer arc surface, and then clamp the positioning column 16.

[0035] Further, a chute 17 is opened on the inner wall of one side of the first half-ring 1. A slider 18 is slidably connected in the chute 17. The inner side of the slider 18 is fixedly connected with a first shaft rod 21. The inner side of the first shaft rod 21 is rotatably connected with a first wire roller 22. An adjusting screw rod 19 is rotatably connected in the chute 17. The adjusting screw rod 19 is threadedly connected with the slider 18. The bottom of the adjusting screw rod 19 extends to the outside of the first half-ring 1 and is fixedly connected with a runner 20.

[0036] Further, a second shaft rod 23 is fixedly connected to the inner wall of the first half-ring 1 close to the chute 17. The inner side of the second shaft rod 23 is rotatably connected with a second wire roller 24. The second wire roller 24 is located directly below the first wire roller 22. Both the second wire roller 24 and the first wire roller 22 are in hourglass structures, so that the device can be fixed to the wire, and during the winding process, it is convenient for the device to move along the direction of the wire.

[0037] Further, docking grooves 25 are opened on the inner walls on both sides of the notch 2. Docking blocks 26 are arranged on both sides of the second half-ring 3. The structures of the docking blocks 26 and the docking grooves 25 match, so that the second half-ring 3 can be stably inserted into the notch 2.

[0038] Further, two fixing seats 27 symmetrically distributed on both sides are fixedly connected to the bottom of the rear end of the first half-ring 1. The same rope 28 is fixedly connected to the two fixing seats 27. A counterweight plate 29 is sleeved on the rope 28, so as to maintain the overall stability of the device.

[0039] Further, an extension rod 30 is fixedly connected to the front end of the winding cylinder 9, and a plurality of uniformly distributed hooks 31 are fixedly connected to the outer side surface of the extension rod 30.

[0040] Further, an ear block 32 is fixedly connected to the rear end of the winding cylinder 9, a handle 33 is rotatably connected to the top of the ear block 32, and the same second spring 34 is fixedly connected between the handle 33 and the winding cylinder 9.

[0041] Working principle: When in use, the first half-ring 1 is sleeved on the wire to be repaired through the notch 2, and then the second half-ring 3 is clamped into the notch 2. The inner rod 13 and the clamping part 15 are pushed into the embedding groove 12. After the clamping part 15 and the positioning column 16 are aligned, the inner rod 13 is released. Under the elastic force of the first spring 14, the clamping part 15 and the positioning column 16 on the inner rod 13 are butted to fix the second half-ring 3. Then the wire to be repaired is placed between the first wire roller 22 and the second wire roller 24. Then the runner 20 is rotated to make the adjusting screw rod 19 rotate, so that the whole of the slider 18, the first shaft rod 21 and the first wire roller 22 move downward, and the wire can be clamped by the first wire roller 22 and the second wire roller 24, so that the device is fixed to the wire; the free end of the preformed strand 10 on the winding cylinder 9 is pulled out and sequentially passed through a plurality of hooks 31. Finally, the free end of the preformed strand 10 is pressed on the wire. The other hand holds the handle 8 and drives the handle 8 to rotate around the wire. The handle 8 follows the connecting column 7 and the movable block 6 and rotates along the first half-ring track 4 and the second half-ring track 5, and the preformed strand 10 can be wound around the wire. By tightly holding the handle 33, the other end of the handle 33 abuts against the winding cylinder 9, and the winding cylinder 9 can be fixed. When the wire feeding of the winding cylinder 9 is stopped, when continuing to wind, the preformed strand 10 wound on the wire can be tightened and wound more tightly; after winding, the preformed strand 10 is cut off from the winding cylinder 9, and the device is removed from the wire.

Under the elastic force of the first spring 14, the clamping part 15 and the positioning post 16 on the inner rod 13 are butted to fix the second half-ring 3. Then, place the wire to be repaired between the first wire roller 22 and the second wire roller 24. Then, rotate the runner 20 to make the adjusting screw 19 rotate, so that the slider 18, the first shaft rod 21 and the first wire roller 22 move downward as a whole, and the wire can be clamped by the first wire roller 22 and the second wire roller 24, thus fixing the device to the wire.
