Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction, in particular to a wire tensioner for electric power construction. Background Art

[0002] Wires are important equipment for ensuring the transmission of electricity. After the installation of the wires, there is a certain distance between the two points where the wires are installed. Due to thermal expansion and contraction, the wires between the two points may become tight or loose, which can easily affect the use of the wires. Therefore, when installing the wires, the wires need to be loosened a certain amount before being tightened and adjusted. The existing publication number CN 113872112 B is a tensioning device for power transmission lines. According to the vertical distance between the line placement groove at the top of the telescopic rod and the wire, the position between the fixed rod and the rotating rod in the telescopic rod is adjusted to control the overall length of the telescopic rod. The wire is placed in the line placement groove at the upper end of the telescopic rod, and the middle of the wire is fixed in the line fixing fixture at the top of the adjustment rod. The telescopic device is operated by a controller to move the adjustment rod downward. The height of the wire can only be adjusted between the telescopic rods, avoiding changes in the overall height of the wire. However, in the above device, the rotating wheel on the line placement groove is fixed relative to the adjustment point of the wire, resulting in a fixed adjustment range for the wire tensioning, which causes inconvenience in use.
