Embodiment 1

[0017] Pull wire anti-twist device, including support plate 1, movable clamp 3, fixed clamp 2. The pallet 1 is a long strip, and the length of the pallet is optimally matched with the length of the cable. One end of the pallet 1 is provided with a sliding groove 6 along the length direction. A movable clamp 3 is installed at one end of the pallet 1 where the sliding groove 6 is provided, and a fixed clamp 2 is installed at the other end of the pallet 1. The fixing clip 2 is composed of two fixing plates 21, which are fixedly installed on both sides of the pallet 1. The fixing plates 21 can have a square or trapezoidal structure, and the trapezoidal structure can be used to clamp the cable. A bolt 4 passing through the pallet 1 is installed between the two fixing plates 21. The movable clamp 3 is composed of two movable clamping plates 31. The two movable clamping plates 31 are installed on both sides of the sliding groove 6 of the pallet. The two movable clamping plates 31 ar...

Embodiment 2

[0020] Such as Figure 1~3 As shown, the difference between this embodiment and Embodiment 1 is that the fixed clamping plate 21 and the movable clamping plate 31 are both stepped with two sections of different thickness. This design is that each step section of different thickness is matched with the width of the pallet so as to be stuck on both sides of the pallet. When in use, different stepped sections can be exchanged and connected to both sides of the pallet, so that the gap between the two fixed clamping plates and the movable clamping plate is also variable, which can be applied to pull wires with different diameters.

Abstract

The invention discloses an anti-distortion device for a bracing wire, comprising a supporting plate with a sliding chute at one end. One end of the supporting plate, which is provided with the sliding chute, is movably provided with a live splint for clamping the bracing wire, and the other end of the supporting plate is provided with a retaining clip. The retaining clip consists of two fixed clamping plates fixedly installed at two sides of the supporting plate. The live splint consists of two movable clamping plates installed at two sides of the sliding chute of the supporting plate, and the two movable clamping plates are connected and fixed by bolts passing through the sliding chute. The fixed clamping plates and the movable clamping plates are both in ladder shapes matched with the supporting plate and having two sections of different thickness. Nuts matched with the bolts are butterfly-shaped nuts. By adopting the anti-distortion device, distortion of the bracing wire is effectively avoided, and time and labor are saved. The anti-distortion device for the bracing wire has the advantages of simple structure, attractive shape, low cost, safety, convenience, convenient carrying and strong adaptability.

Description

Technical field [0001] The invention relates to a tool used for pulling wires of transmission lines, in particular to a wire pulling anti-torsion device. Background technique [0002] The construction specifications for low-voltage overhead lines require that load-bearing poles such as swelling resistance, corners, branches, terminals and spans should be installed with pull wires to balance the force of the poles and ensure the stability of the line. Low-voltage overhead power distribution lines generally use galvanized steel stranded wire as the cable. The manufacturing process of the cable is to first bend the ends of the cable and fold it in half, and then use the steel wire to tightly wrap the head of the bent part. In the process of pulling wire, the tail wire and the main wire are often twisted and deformed, which affects the process standard. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a pull wire anti-torsion...
