[0002] A wire tensioner, also known as a ratchet tensioner, is used to tighten conductors during overhead line installation. To use it, first loosen the steel or galvanized wire from the tensioner and secure it to the crossarm. Then, clamp the conductor with a wire clamp and use a special wrench. In daily life, wire tensioners are often used to tighten wires.

[0003] The authorization announcement number CN219892810U discloses a power transmission and transformation line tensioner, including a winding assembly and a clamping assembly fixed to the winding assembly, the clamping assembly includes a first clamping disk and a second clamping disk hinged on the first clamping disk, the first clamping disk is hinged with a connecting member for connecting the first clamping disk and the second clamping disk; the winding assembly includes a connecting frame, a turntable rotatably connected in the connecting frame and a driving member for driving the turntable to rotate, wherein the turntable can pay out or reel in the power transmission and transformation line when it rotates, solving the problem that the traditional tensioning device lacks a fixed structure and is inconvenient for aerial winding operations.

[0004] Although the above-mentioned solution solves the problem that the traditional wire tightening device lacks a fixed structure and is inconvenient for aerial wire winding operations, the wires lack guidance during the tightening process. When the wires are wound on the disc, they are prone to loosening and becoming disordered. For this reason, we propose a power transmission and transformation line tightener. Utility Model Content

[0005] The main purpose of the utility model is to provide a transmission and transformation line tensioner, which solves the problem that the wires are easily loose and scattered when wound on the disc due to lack of guidance for the wires during the tensioning process by setting a guide unit and a connecting unit.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A power transmission and transformation line tensioner comprises a main body unit, a winding unit and a guide unit arranged in the main body unit, and a connecting unit arranged on the side of the main body unit;

[0008] The guide unit includes a threaded shaft movably arranged inside the main unit, a driving motor installed at the input end of the threaded shaft, a moving part installed on the circumferential side of the threaded shaft, and a combing part arranged on the side of the moving part;

[0009] The connecting unit includes a first clamping disc installed on the side of the main body unit, a second clamping disc movably installed on the side wall of the first clamping disc, and a clamping member disposed between the first clamping disc and the second clamping disc.

[0010] Preferably, the main body unit includes a fixed box and a winding roller movably installed in the fixed box.

[0011] Preferably, the winding unit includes a turbine installed on the side wall of the winding roller, a U-shaped seat installed on the inner side wall of the fixed box, a worm movably installed in the U-shaped seat, and a driving member disposed at the end of the worm.

[0012] Preferably, the driving member includes a rotating disc installed at the input end of the worm and a handle installed on the side wall of the rotating disc.

[0013] Preferably, the combing member includes a C-shaped seat installed on the side wall of the moving member and a wire guiding wheel movably installed in the C-shaped seat.

[0014] Preferably, the guiding unit further includes a limiting washer installed on the inner side wall of the fixed box, and the limiting washer is sleeved on the circumferential side of the threaded shaft.

[0015] Preferably, the clamping member includes a rotating groove opened on the side wall of the first clamping disc, a clamping groove opened on the side wall of the second clamping disc, a threaded rod movably installed in the rotating groove, and a nut installed on the circumferential side of the threaded rod.

[0016] Compared with the prior art, the present utility model has the following beneficial effects:

[0017] In the present utility model, through the arranged guiding unit and connecting unit, when it is necessary to tighten the wire, the inner wall of the first clamping disc is abutted against the transmission and transformation electric pole. Subsequently, after rotating the second clamping disc to approach the second clamping disc, the threaded rod is inserted into the clamping groove on the side wall of the second clamping disc. Then, the nut is screwed onto the threaded rod to complete the fixation before tightening, which facilitates the operation of the staff. When performing the wire tightening operation, by rotating the handle, the rotating disc drives the worm to rotate, and the worm drives the turbine to rotate, so that the winding roller tightens and winds the wire. During the process of tightening and winding, the driving motor drives the threaded shaft to rotate, and the moving member drives the wire guiding wheel to move along the threaded shaft, so that the wire is evenly wound on the surface of the winding roller, avoiding slack and scattering during wire tightening.
