Its main function is to be used as a tool for tensioning the cable during the construction of the overhead line laying. Through its unique mechanical structure, it can effectively tension the cable to the required tension state to ensure the stability and safety of the line.

[0024] Embodiment 1:

[0025] According to Figure 1 and Figure 2 As shown, it includes a housing 1, a driving component, a connecting seat 23, a turnbuckle 4, and a fixture for clamping a cable. The interior of the housing 1 is hollow, and its top is open.

[0026] One end of the housing 1 is provided with a fixed clamping plate 31 and a movable clamping plate 34 for clamping a cross arm. The fixed clamping plate 31 is welded to the bottom of the housing 1. The fixed clamping plate 31 and the movable clamping plate 34 are detachably connected by a connecting member. The connecting member includes a stud 33. One end of the stud 33 is welded to the fixed clamping plate 31, and the other end passes through a reserved hole of the movable clamping plate 34 and is threadedly connected with a fastening nut 32. By tightening the fastening nut 32, the movable clamping plate 34 and the fixed clamping plate 31 clamp the cross arm, and the housing 1 is fixed on the cross arm.

[0027] The driving component includes a threaded rod 21 and a moving nut 24. Bearings are sleeved on the optical axes at both ends of the threaded rod 21, and the two bearings are respectively installed on the left and right side walls of the housing 1, enabling the threaded rod 21 to rotate stably.

[0028] One end of the threaded rod 21 is installed with a rotating rod 22 for driving the threaded rod 21 to rotate. The moving nut 24 is threadedly connected with the threaded rod 21, and its top is fixedly connected with the connecting seat 23. By rotating the rotating rod 22 to drive the rotation of the threaded rod 21, the threaded rod 21 drives the connecting seat 23 to move horizontally through the moving nut 24 during rotation.

[0029] One end of the turnbuckle 4 is fixedly connected with the connecting seat 23. The fixture includes a connecting nut 51 and two arc-shaped clamping plates 53. The two arc-shaped clamping plates 53 are connected by bolts 52. The connecting nut 51 is welded to the bottom of any one of the arc-shaped clamping plates 53. The connecting nut 51 is threadedly connected with the turnbuckle 4, enabling the fixture and the turnbuckle 4 to be detachably separated, facilitating the replacement of the fixture. By connecting the turnbuckle 4 with the fixture, on the one hand, the position of the fixture can be adjusted according to the tension requirement of the cable, and on the other hand, by operating the turnbuckle 4, the tension can be further adjusted.

[0030] This wire tightener is driven by a threaded rod 21, has a simple structure, low maintenance requirements, and by controlling the rotation of the threaded rod 21, force can be continuously applied until the required tightness is reached, providing more precise tension control and maintaining the tension.

[0031] During specific use, for a wire tightener for electric power construction of the present utility model, first, the fixed clamping plate 31 is brought into contact with the cross arm, and the movable clamping plate 34 is put on the stud 33. By successively screwing the fastening nuts 32, the movable clamping plate 34 and the fixed clamping plate 31 are made to clamp the cross arm, and the housing 1 is fixed on the cross arm. Then, the turnbuckle 4 is rotated to adjust the position of the arc-shaped clamping plate 53 so that the arc-shaped clamping plate 53 contacts the cable. Then, multiple bolts 52 are used to connect the two arc-shaped clamping plates 53, and then the cable is clamped and fixed. Finally, the rotating rod 22 is rotated to drive the rotation of the threaded rod 21. During the rotation of the threaded rod 21, the connecting seat 23, the turnbuckle 4, and the fixture are driven by the moving nut 24. During the continuous movement of the fixture, the cable is tightened to the required tension state to ensure the stability and safety of the line.
