[0023] As attached Figure 1 To be continued Figure 5 As shown:

[0024] This utility model provides a conductor lifting device for high-voltage transmission lines, including a housing 1, a fixed housing 2, and a movable frame 12;

[0025] The lower end of the outer shell 1 is provided with a sliding groove 101. The inside of the outer shell 1 is connected to a baffle 11, and a second sliding groove 1101 is provided on the baffle 11. The upper end of the outer shell 1 is fixedly connected to a fixing rod 5. The fixed outer shell 2 is placed on the upper end of the fixing rod 5, and the fixed outer shell 2 is provided with two sets of grooves. A connecting rod 6 is installed in the grooves on the fixed outer shell 2. A small baffle 601 is connected to the connecting rod 6. A rack 602 is connected to the inner side of the two sets of connecting rods 6. Four sets of movable frames 12 are installed inside the outer shell 1. A cable rack is installed inside the movable frame 12. The cable rack is provided with a groove, and a cable 9 is provided on the cable rack. The lower end of the cable 9 passes through the sliding groove 101. A square hole is provided on the inner side of the rear end of the movable frame 12.

[0026] Among them, such as Figure 2 As shown, the upper end of the fixed housing 2 is provided with a rotating cover 8, and the lower end of the rotating cover 8 is fixedly connected to a connecting rod 801. The lower end of the connecting rod 801 is connected to a gear 802, which meshes with a rack 602. Positioning parts 7 are connected to the two sets of connecting rods 6, and threaded holes are provided at the lower end of the positioning parts 7. Threaded rods 701 are movably connected in the threaded holes on the positioning parts 7. By rotating the rotating cover 8, the two sets of connecting rods 6 can be quickly moved, which can facilitate quick and easy installation and fixation, and is conducive to adapting to different installation scenarios.

[0027] Among them, such as Figure 4 As shown, a rotating rod 3 is connected to the movable frame 12. The rotating rod 3 has locking components A301 on both sides, which are locked into grooves on the cable rack. A locking component B302 is connected to the rear end of the rotating rod 3, and is locked into a square hole on the inner side of the rear end of the movable frame 12. The front end of the rotating rod 3 extends through a sliding groove 1101, and an anti-slip sleeve 4 is connected to the outer side of the front end of the rotating rod 3. By moving the rotating rod 3, the locking component B302 is pulled out. Rotating the rotating rod 3 drives the cable rack, causing the cable 9 to descend or rise. This facilitates control of the cable lifting height during operation and makes subsequent operations easier for staff.

The rotating rod 3 can be moved to pull out the clamping part B302. Rotating the rotating rod 3 can drive the cable rack to lower or raise the cable 9, which is conducive to controlling the lifting height during operation and facilitates subsequent operation by the staff. After the height is determined, the rotating rod 3 can be pushed to re-clamp the clamping part B302 into the square hole on the inner side of the rear end of the movable frame 12. The clamping frame 10 can be used to fix the wires and is conducive to adapting to more different wires.
