Description

Technical Field

[0001] The utility model relates to the technical field of line tensioners, and more specifically, to a line tensioner for electric power construction. Background Art

[0002] During the construction of power lines, tightening the lines is a very important task. If the lines are too loose, they may collide with each other and cause a short circuit. If the lines are too tight, they may cause the wires to break or the poles to break.

[0003] The existing structure does not have a self-locking function, and the line tightening function is achieved by manually operating the rotating handle, which is inefficient and labor-intensive, especially during high-altitude operations.

[0004] After searching, a Chinese patent with authorization announcement number CN208337035U discloses a wire tensioner for power construction. The mechanism fixes the conductor on the insulator, operates the servo motor to loosen the rope on the rotating roller, hangs the rear hook on the crossarm, and then hangs the conductor on the front hook. The servo motor is operated to drive the rotating roller to rotate, and gradually winds the rope around the rotating roller, thereby tightening the conductor. During the conductor tightening operation, since the helix angle of the worm is smaller than the equivalent friction angle of the meshing surface, the worm gear transmission mechanism itself has a self-locking effect and is very reliable and not prone to accidents. The servo motor controls the direction of the rotation speed of the rotating roller through the worm gear rotation mechanism, which not only improves work efficiency and greatly reduces the labor intensity of operators, but also has a reliable self-locking function and improves the safety factor.

[0005] However, when this structure is actually used, the rear hook is hung on the cross arm, and the wire is then hung on the front hook for fixing. Due to the gap between the hook and the cable, the tensioner is prone to shaking during operation, making the clamping position of the cable on the tensioner inaccurate, resulting in loose cable installation, which affects the tensioning effect of the tensioner.
