Auxiliary pull ring manufactured from power stay wire and method for manufacturing stay wire

Abstract

The invention belongs to the technical field of stay-wire-manufactured appliances and discloses an auxiliary pull ring manufactured from a power stay wire and a method for manufacturing the stay wire. The auxiliary pull ring is mainly characterized by comprising a semi-cylindrical pipe body, wherein a U-shaped hugging column wing is arranged below the pipe body, and a through hole is formed in the hugging column wing; a pin shaft is arranged in the through hole, and a hanging ring is arranged on the side face close to the upper end of the pipe body. During manufacturing the stay wire, the pipe body sleeves a stay wire rod, and the upper end of the pin shaft is clamped at the end part of welding of a stay wire rod bending ring; at the moment, the hanging ring and the stay wire rod bending ring are in the same plane or the planes of the hanging ring and the stay wire rod bending ring are mutually parallel; the upper end of the hanging ring and the stay wire rod bending ring are propped against each other, so that a wire grip and the stay wire form a certain angle; when the manufactured stay wire is withdrawn, the wire grip is not overlapped with the stay wire yet, a lower hook or a steel wire rope sleeve of the wire grip is arranged the hanging ring, and the lower end of a UT wire clamp is arranged in the stay wire rod bending ring, so that the lower hook or the steel wire rope sleeve of the wire grip and the UT wire clamp cannot be mutually clamped, the wire grip is convenient to dismount. The working efficiency and the manufacture quality of the stay wire are improved.

Description

technical field [0001] The invention belongs to the technical field of pull wire production equipment and methods, and in particular relates to a method for making auxiliary pull rings and pull wires for electric power pull wires. Background technique [0002] In the line erection construction, in order to ensure the stability of the tower, it is necessary to make the tower stay wire on the tower. The strands usually need to be tightened before making the pull downs. At present, most of the tightening tools for tightening steel strands are ratchet-type multi-functional tighteners. In view of the different bearing forces of the pull wires, the diameters of the pull rods are also different. When fixing on a pull rod with a diameter of 28-25mm, due to the large diameter of the pull rod, the hook head of the wire tensioner cannot be directly connected with the pull rod. The hook head is set on the wire rope sleeve. When the wire tensioner is fixed directly or through the wire...

AI Technical Summary

Problems solved by technology

When the wire tensioner is fixed directly or through the wire rope sleeve and the wire rod, the wire tensioner will overlap with the wire to be made, which will bring inconvenience to the production of the lower handle of the wire and the installation of the UT wire clamp.

During the installation process, both the wire rope sleeve and the UT wire clamp are in the bending ring of the pull rod at the same time. When tightening the wire or tightening the bolts on the UT wire clamp, the wire rope sleeve and the UT wire clamp are blocked by each other, making it difficult to disassemble the wire tensioner. Reduce work efficiency and even affect the quality of cable production
