[0002] Insulators are devices installed between conductors at different potentials or between a conductor and a grounding component, which can withstand voltage and mechanical stress. There are various types of insulators with different shapes. Although different types of insulators have great differences in structure and shape, when a local part of an insulator string is damaged at high altitude, the whole insulator string needs to be taken down for maintenance, which is a cumbersome process and cannot be directly repaired locally, resulting in low work efficiency. Summary of the Invention

[0015] The present invention will be further described below with reference to embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figure 1-5 This invention provides an auxiliary device for replacing insulator strings, comprising two connecting blocks 10, each with a fixing mechanism 11. Two telescopic rods 12 are positioned between the two connecting blocks 10. Each telescopic rod 12 includes an outer cylinder 121 and an inner rod 122. The outer cylinder 121 is sleeved on the inner rod 122. A rotating component 13 is sleeved on the end of the outer cylinder 121 away from the inner rod 122. A winding rod 14 is connected to the end of the rotating component 13 near the outer cylinder 121. The winding rod 14 is laterally positioned inside the outer cylinder 121, and a pull rope 15 is wound around it. The side of the pull rope 15 away from the winding rod 14 is connected to the inner rod 122. A vertical disc 16 is connected to the inner wall of the outer cylinder 121, located on the side of the winding rod 14 away from the rotating component 13. The vertical disc 16 is positioned on one side of the winding rod 14. A compression spring 17 is connected, with one end of the compression spring 17 away from the vertical plate 16 connected to one end of the inner rod 122. The pull rope 15 passes through two fixed pulleys 18, the vertical plate 16, and the compression spring 17 in sequence. The fixed mechanism 11 separates the damaged area of ​​the insulator string 22. Rotating the rotating part 13 releases the pull rope 15, causing the inner rod 122 to move under the elastic force of the compression spring 17, thus lengthening the telescopic rod 12. Rotating the rotating part 13 in the opposite direction drives the winding rod 14, which winds the pull rope 15. The pull rope 15 pulls the inner rod 122, shortening the telescopic rod 12. This adjusts the distance between the two fixed mechanisms 11, allowing for the selection of damaged areas of different lengths, facilitating localized repairs of the insulator string 22 and increasing work efficiency.

[0018] Please see Figure 1-3A fixed pulley 18 is installed inside the outer cylinder 121, and there are two fixed pulleys 18 with different sizes. The direction of the pulling rope 15 and the winding rod 14 is changed through the two fixed pulleys 18, which facilitates the winding by the winding rod 14.

[0019] See Figure 1-3 The rotating member 13 is in a king-shaped configuration. A connecting cylinder 19 is sleeved on a side of the rotating member 13 away from the outer cylinder 121, and one end of the connecting cylinder 19 away from the rotating member 13 is connected with a connecting block 10. The rotating member 13 can rotate without being separated from the connecting cylinder 19 and the outer cylinder 121. When the rotating member 13 rotates, it drives the winding rod 14 to rotate, providing rotational power for the winding rod 14.

[0020] See Figure 1 , Figure 2 , Figure 4 and Figure 5 Each of the two connecting blocks 10 is provided with an arc-shaped slot 101, and a sliding slot 102 is radially opened on the inner wall of the arc-shaped slot 101. The fixing mechanism 11 comprises a transverse rod 111, an arc-shaped tooth plate 112, a pull rod 113, an adjusting spring 114 and a limit block 115. Two ends of the transverse rod 111 are transversely connected in the arc-shaped slot 101, the arc-shaped tooth plate 112 is sleeved on the transverse rod 111, the limit block 115 is arranged in the sliding slot 102, one end of the limit block 115 away from the arc-shaped tooth plate 112 is connected with the adjusting spring 114, and the other end of the adjusting spring 114 is connected to the inner wall of the sliding slot 102. One end of the pull rod 113 passes through the adjusting spring 114 and is connected with the limit block 115. A side of the limit block 115 close to the arc-shaped tooth plate 112 is arc-shaped. When the arc-shaped tooth plate 112 is pressed and covered, since one side of the limit block 115 is arc-shaped, the arc-shaped tooth plate 112 abuts against the limit block 115, and the limit block 115 will retreat, then move back under the elastic force of the adjusting spring 114, so that the limit block 115 is clamped between the clamping slots of the arc-shaped tooth plate 112, thereby fixing the insulator string 22.

[0021] See Figure 1 , Figure 2 , Figure 3 and Figure 5 A groove 20 is opened on a side of the outer cylinder 121 close to the rotating member 13, and an abutting assembly 21 is arranged inside the groove 20. The abutting assembly 21 comprises an abutting spring 211 and an abutting block 212. Two ends of the abutting spring 211 are respectively connected with one end of the abutting block 212 and the inner wall of the groove 20, and the other end of the abutting block 212 abuts against the rotating member 13. The friction force between the abutting block 212 and the rotating member 13 is greater than the elastic force of the compression spring 17. The friction force between the rotating member 13 and the abutting block 212 is increased through the elastic force of the abutting spring 211, so that the rotating member 13 cannot rotate by itself, which improves the stability of the rotating member 13.

[0022] The working principle of this invention is as follows: First, one end of the insulator string 22 that is undamaged and close to each other is placed in an arc-shaped groove 101. When the arc-shaped toothed plate 112 is pressed down, because one side of the limiting block 115 is arc-shaped, the arc-shaped toothed plate 112 abuts against the limiting block 115, and the limiting block 115 will move backward. Under the elastic force of the adjusting spring 114, it moves back, so that the limiting block 115 is stuck between the slots of the arc-shaped toothed plate 112, thereby fixing the insulator string 22. Rotate the two rotating parts 13. Rotating the rotating parts 13 causes the winding rod 14 to loosen the pull rope 15, so that the inner rod 122 moves under the elastic force of the compression spring 17, so that... The telescopic rod 12 becomes longer. When the rotating part 13 is rotated in the opposite direction, the rotating part 13 drives the winding rod 14. The winding rod 14 winds the pull rope 15, and the pull rope 15 pulls the inner rod 122, making the telescopic rod 12 shorter. This adjusts the distance between the two fixing mechanisms 11, allowing for the selection of damaged areas of different lengths. Then, the undamaged insulator string 22 at the other end is fixed, allowing the damaged insulator string 22 to be disassembled without the undamaged insulator string 22 falling off. When disassembly is required, the pull rod 113 is pulled, causing the limit block 115 to separate from the arc-shaped toothed plate 112, allowing for quick disassembly and replacement of the auxiliary device.

[0023] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description, and these obvious variations or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
