[0019] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them.

Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0020] Example:

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this utility model provides a conductor lifting device for high-voltage transmission lines, including a crossbar 1, an installation groove 2 inside the crossbar 1, a lifting hook 5 below the crossbar 1, a connecting rod 3 connected to the upper end of the lifting hook 5, a limiting groove 21 at the upper end of the connecting rod 3, the connecting rod 3 being sleeved in the installation groove 2 through the limiting groove 21 and slidably connected to the crossbar 1, a movable groove 22 on one side of the connecting rod 3 located in the limiting groove 21, a baffle 11 rotatably connected to the outside of the connecting rod 3 located below the movable groove 22, an installation block 14 fixed to the outside of the connecting rod 3 located above the movable groove 22, a buckle 15 connecting the baffle 11 and the installation block 14, multiple sets of slots 18 evenly arranged laterally at the bottom of the installation groove 2, an installation cavity 16 opening upward on the upper surface of the limiting groove 21, a fixing rod 19 extending into one set of slots 18 penetrating the installation cavity 16;

[0022] When using this device, the wire can be lifted using the lifting hook 5, and the number of lifting hooks 5 can be selected as needed. When adding lifting hooks 5, the movable groove 22 on one side of the connecting rod 3 can be aligned with the bottom of the mounting groove 2, and the connecting rod 3 can be fitted into the mounting groove 2 through the movable groove 22 and the limiting groove 21. At this time, the baffle 11 can be rotated so that its end is close to the mounting block 14, and the two can be fixed together by the buckle 15, preventing the connecting rod 3 from slipping off the crossbar 1 through the movable groove 22. Through the above operation, the connecting rod 3 can be fixed on the crossbar 1. Similarly, when disassembling the connecting rod 3, simply unfasten the buckle 15. Furthermore, by lifting the fixing rod 19 upwards away from the slot 18, the connecting rod 3 can be moved to slide inside the mounting groove 2 to adjust the distance between multiple sets of lifting hooks 5. This facilitates the adjustment of the distance between multiple sets of wires. After adjusting to the appropriate position, the fixing rod 19 is released and inserted into the corresponding slot 18 at the bottom of the mounting groove 2 to fix the position of the connecting rod 3 and the lifting hook 5. Therefore, when using this device, it is possible to determine whether to add lifting hooks 5 according to the required number of lifting hooks 5 and quickly install them between them and the crossbar 1. At the same time, it is also possible to control and adjust the distance between each set of wires, making it convenient for lifting different numbers of wires.

[0023] like Figure 2 , Figure 4 As shown, the lower end of the baffle 11 is provided with a rotating hole 13, and a T-shaped rod 12 fixedly connected to the outer wall of the connecting rod 3 is inserted into the rotating hole 13. The baffle 11 is rotatably connected to the connecting rod 3 through the T-shaped rod 12 and the rotating hole 13. By inserting the T-shaped rod 12 into the rotating hole 13 and fixing it on the connecting rod 3, the baffle 11 can be easily installed on the connecting rod 3, while ensuring that the baffle 11 and the connecting rod 3 are rotatably connected.

[0024] like Figure 1 ,Figure 2 , Figure 3 As shown, a spring 17 is provided inside the mounting cavity 16. The upper end of the spring 17 abuts against the upper end surface of the mounting cavity 16, and a limiting plate 20 is fixed to the lower end of the spring 17. The limiting plate 20 is fixedly connected to the fixing rod 19. The spring 17 is sleeved on the outside of the fixing rod 19, and the upper end of the fixing rod 19 extends out of the upper end of the connecting rod 3 and is connected to the limiting block 9. When using this device, when it is necessary to adjust the distance between each group of wires, the fixing rod 19 can be lifted upward by lifting the limiting block 9 to move it upward away from the slot 18, and at the same time, it will move upward with the fixing rod. The fixed limiting plate 20 is moved upward and compresses the spring 17. At this time, the connecting rod 3 can be pushed to slide inside the mounting groove 2 to adjust its position, so as to facilitate the synchronous movement of the lifting hook 5 and the wire. After moving to the appropriate position, the limiting block 9 is released. At this time, the spring 17 resets itself and pushes the limiting plate 20 downward, so that the fixed rod 19 is inserted into the corresponding slot 18. This fixes the position of the connecting rod 3, so that the distance between each group of wires is kept constant and the wires are prevented from intertwining during the lifting process.

[0025] like Figure 1 As shown, a mounting base 7 is fixed to one side of the lifting hook 5. A limiting rod 6 is connected to the mounting base 7. A tightening bolt 8 is rotatably connected to the mounting base 7. The tightening bolt 8 is threadedly connected to the mounting base 7. A threaded groove is opened upward at the bottom of the connecting rod 3. A threaded rod 4 extending out of the bottom of the connecting rod 3 is threadedly connected in the threaded groove. The threaded rod 4 is fixedly connected to the lifting hook 5. A lifting ring 10 is fixed to the upper end of the crossbar 1. By setting the limiting rod 6, it is convenient to rotate the lifting hook 5 after the wire is installed inside the lifting hook 5. The limiting rod 6 is positioned above the wire and the lifting hook 5, forming a closed hole between them that allows the wire to pass through. The limiting rod 6 is then fixed by tightening the screw 8, which helps to secure the wire inside the lifting hook 5 and prevents it from slipping during lifting. The distance between the lifting hook 5 and the crossbar 1 can be easily adjusted by setting the threaded groove and threaded rod 4, making it suitable for different application scenarios. The lifting ring 10 is fixed above the crossbar 1, which facilitates the lifting of the device through the lifting ring 10, thereby lifting the wire.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
