Most transmission line tensioners use single-pulley tensioners, which are located under the crossarm. The transmission line passes through the pulley and is manually dragged below. To hang the transmission line on the hanging point above the crossarm, cooperation between the upper and lower personnel is required to hang it on the designated hanging point above the crossarm.

[0003] In case of a straight tower pole, the tightening direction of the two pulleys is in a straight line with the tightening direction of the transmission line, and the transmission line is passed through the two pulleys.

[0020] The existing tensioner cannot be adjusted after being fixed. Since the positions of insulators and cross arms on different poles are different, it is inconvenient for users to tighten the line if the relative distance is large, which reduces the application range of the device.

[0021] In view of this, a transmission line erection tensioner is provided, which realizes adjustment of the frame height through the cooperation between the screw, the sleeve and the shell. The user can adjust it according to the tightening position, which solves the problem that the position of the existing tensioner cannot be adjusted after being fixed. Since the positions of insulators and crossarms on different poles are different, it is inconvenient for users to tighten the line if the relative distance is large, which reduces the scope of application of the device.

[0024] In the specific implementation process, it is worth pointing out that the screw rod 3 can be rotated through the bearing, and the height of the frame body 1 can be adjusted through the cooperation between the screw rod 3, the sleeve 4 and the handle 21. The user can adjust it according to the position of the tightening wire, which solves the problem that the position of the existing tightening wire device cannot be adjusted after being fixed. Since the positions of the insulators and cross arms on different poles are different, if the relative distance is large, it is inconvenient for the user to tighten the wire, which reduces the application range of the device;

[0031] In the specific implementation process, it is worth pointing out that the device relies on the elastic deformation of the spring 18 to drive the insertion rod 17 to always be inserted into the inner groove of the frame 1 for fixing. A plurality of grooves are processed on the inner side of the frame 1 to adjust the angle of the upper shaft 14. The specific opening position is not limited. When adjustment is required, just pull the insertion rod 17 downward;

[0033] In the specific implementation process, it is worth pointing out that the positioning rod 16 can be inserted into the through holes of the vertical plate 13 and the seat body 12 for positioning, thereby realizing the disassembly of the shaft body 14;

[0034] Specifically, based on the above-mentioned embodiment 1, the angle of the shaft 14 is adjusted through the cooperation between the bottom plate 11, the spring 18 and the back plate. The user can rotate it according to the wiring needs. The whole process is convenient for the user to operate and improves work efficiency.
