Description

Tool for fastening loose stay wire

Technical Field

The utility model relates to the technical field of power transmission auxiliary devices, in particular to a tool for fastening and loosening a stay wire.

Background

The stay wire is an important component part of the distribution line, and the common stay wire is also called a floor stay wire, and has the main functions of balancing unbalanced tension of a wire and stabilizing a pole tower, so that the stress intensity of the pole tower is reduced. The stay wire in the prior art is divided into an upper part and a lower part, wherein the upper part comprises an upper handle fixed on the upper part of the electric pole and a part connected with the upper handle, and the lower part comprises a ground anchor handle or pull ring, a stay wire rod and a part buried underground, which is called a bottom handle. The middle of the stay wire is provided with a hardware fitting for adjusting the tightness, generally a UT wire clamp, and an electric shock preventing insulator is additionally arranged in the middle of the stay wire with the voltage of 10kV or below. The common pull wire of the power line with the voltage class of 10kV and below forms an included angle of 45 degrees with the electric pole.

The tower stay wire can loose due to severe weather, corrosion of stay wire connection parts and other problems after the line is operated for several years, and the safety problems such as pole falling, crossarm torsion and the like are easy to occur. In order to eliminate such a safety hazard,

the current common stay wire adjusting method is that a worker climbs a pole after power failure, and adjusts the stay wire by the position of a wire clamp at the upper end of the stay wire or adjusts the stay wire by the position of a UT wire clamp at the lower end of the stay wire without power failure. Because the stay wire is often stolen, the UT wire clamp at the lower end of the stay wire is generally covered by an anti-theft facility. If the loose stay wire is adjusted without power failure, the anti-theft equipment needs to be destroyed, so that great economic loss is caused. After power failure, the staff climbing operation is adjusted by the wire clamp at the upper end of the stay wire, certain electric quantity is required to be lost, and certain safety risks can exist in the staff climbing operation.
