High-voltage overhead lines can transmit electrical energy hundreds of kilometers away, meeting the needs of long-distance power transmission. They can transmit large amounts of electrical energy to ensure the stable use of the West-to-East Power Transmission Project and are an important part of the power grid. However, they are very difficult to erect. Therefore, it is necessary to ensure the stability of the overhead lines during the erection process to reduce the failure rate in subsequent use and ensure the stable and efficient operation of the power grid.

[0003] However, existing overhead lines are tightened from the outside, which can cause displacement or even damage to the external insulation material, leading to installation failure and making it difficult to effectively connect to the power grid quickly. To avoid the above technical problems, it is necessary to provide an overhead line that can be tightened to overcome the defects in the existing technology. Summary of the Invention

[0031] The inner side of the insulating rubber sleeve 1 is provided with a connecting groove 201, the inner side of the connecting groove 201 is embedded with a connecting plate 202, the inner side of the connecting plate 202 is provided with a fixing groove 203, the inner side of the fixing groove 203 is embedded with a battery cell 204, and a snap-fit ​​groove 205 is provided at the middle position of the inner side of the connecting plate 202.

[0032] A snap-fit ​​plate 206 is embedded inside the snap-fit ​​groove 205. A damping groove 207 is formed on the outer side of the snap-fit ​​plate 206. The snap-fit ​​plate 206 is snapped into the snap-fit ​​groove 205 through the damping groove 207. Several fixing grooves 203 are formed, and the fixing grooves 203 are equally spaced inside the connecting plate 202 to facilitate pulling the connecting plate 202. A connecting pipe 208 is welded to one end face of the snap-fit ​​plate 206. A limit groove 209 is formed on the outer side of the connecting pipe 208. A limit block 210 is embedded inside the limit groove 209. The connecting pipe 208 is provided with... There are two connecting tubes 208 symmetrically welded to the two end faces of the clamping plate 206. The pull cable 211 is welded to the limiting block 210, which is conducive to pulling the entire cable. The pull cable 211 is connected to the inner side of the connecting tube 208. The inner diameter of the connecting tube 208 is equal to the outer diameter of the pull cable 211. The inner side of the connecting tube 208 is provided with a movable groove at the corresponding position of the pull cable 211. Several connecting plates 202 are provided. Several connecting plates 202 are equidistantly sleeved on the outside of the battery cell 204 to facilitate the connection of multiple connecting plates 202.

[0033] One end of the pull cable 211 is equipped with a coiling assembly 3;

[0034] The winding assembly 3 includes a base 301, a rotating shaft 302, a take-up roller 303, a stop plate 304, a take-up groove 305, and a handle 306;

[0035] A base 301 is provided on one side of the pull cable 211. A rotating shaft 302 is welded to the top of the base 301. A take-up roller 303 is sleeved on the outside of the rotating shaft 302. A rotating groove is opened on the inner side of the take-up roller 303 at the position corresponding to the rotating shaft 302. The take-up roller 303 is rotatably connected to the rotating shaft 302 through the rotating groove, which facilitates the tightening of the overhead line. A stop plate 304 is welded to the top of the rotating shaft 302. A take-up groove 305 is opened on the outer side of the take-up roller 303. A handle 306 is welded to the top of the take-up roller 303.

[0036] The working principle and usage process of this utility model are as follows: First, when the overhead line is being erected, the limiting block 210 can be moved by pulling the cable 211. At this time, the limiting block 210 will move the connecting pipe 208 through the limiting groove 209. Then, during the movement of the connecting pipe 208, the locking plate 206 will be moved. Since the locking plate 206 is locked with the connecting plate 202 through the damping groove 207, the connecting plate 206 and the locking groove 205 can be used to move the connecting plate 202. Subsequently, the connecting plate 202 can be used to move the battery cell 204 inside the fixing groove 203. The connecting plate 202 will also drive the pulling cable 211 on the other side. The cable can be moved because several connecting discs 202 are installed on the outside of the battery core 204. When the pulling cable 211 is pulled, all the connecting discs 202 can be moved at the same time. These connecting discs 202 will pull the entire cable to move at the same time. Since the connecting discs 202 are engaged with the inner side of the insulating rubber sleeve 1 through the connecting groove 201, the insulating rubber sleeve 1 will be moved from the inside to the outside by the connecting discs 202. When the cable is erected at high altitude, it is not necessary to pull the insulating rubber sleeve 1 from the outside to tighten the overhead line. Tightening the overhead line from the inside to the outside prevents the insulating rubber sleeve 1 from being forcibly displaced and damaged, ensuring that the insulation of the overhead line is not affected, and further improving the stability of the overhead line.

[0037] Next, when tightening the cable 211, the operator fixes the base 301 to the tower, and then winds the cable 211 inside the winding groove 305 inside the winding roller 303. Then, the operator can hold the handle 306 to drive the winding roller 303 to rotate outside the rotating shaft 302. At this time, the winding roller 303 will rotate at the bottom end of the stop plate 304. Then the winding roller 303 will continuously wind the cable 211, thereby continuously tightening the overhead line and further improving the laying efficiency of the overhead line.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
