A pre-twisted damping anti-vibration hammer

Abstract

A pre-twisted damping anti-vibration hammer. The invention relates to the improvement of a pre-twisted anti-vibration hammer upper wire clip structure. It can effectively enhance the anti-loosening and anti-slip capabilities of the anti-vibration hammer, ensure the accurate installation position of the anti-vibration hammer and protect the cable from damage. It includes a wire clip, the upper part of which is hook-shaped, and the hook-shaped hook surface is a wire clamping surface, and a damping anti-skid pad is provided on the wire clamping surface. The invention increases the sliding friction force between the anti-vibration hammer and the cable, improves the anti-sliding ability of the anti-vibration hammer, ensures the correct installation position of the anti-vibration hammer, and can protect the cable from damage. In order to ensure the reliability of the connection between the damping anti-slip pad and the clamp, a bump and a mounting hole are provided, and the elasticity of the material of the damping anti-slip pad is used to embed the bump into the mounting hole; it can prevent the damping pad from slipping relative to the anti-vibration hammer verb: move. In order to increase the reliability of the connection with the wire, the curvature of the upper part of the clamping surface is also reduced to be smaller than the curvature of the wire, which is equivalent to clamping the wire in a small arc.

Description

technical field [0001] The invention relates to an anti-vibration hammer of electric power transmission equipment, in particular to an improvement on a pre-twisted type anti-vibration hammer upper wire clip structure. Background technique [0002] Breeze vibration is the main vibration form of overhead cables, and it is also the most harmful vibration to cables. In order to reduce and avoid damage to cables caused by breeze vibration, anti-vibration hammers are usually hung on cables to effectively reduce the vibration amplitude and frequency of cables under wind conditions, thereby reducing fatigue damage and fracture of cables and prolonging the service life of cables. [0003] The anti-vibration hammer is suspended on the cable through the anti-vibration hammer clamp. The existing anti-vibration hammer clamp has loose clamping during use, which causes the anti-vibration hammer to slip, resulting in inaccurate positioning of the anti-vibration hammer and damage to the cabl...

[0003] The anti-vibration hammer is suspended on the cable through the anti-vibration hammer clamp. The existing anti-vibration hammer clamp is loose during use, which causes the anti-vibration hammer to slip, resulting in inaccurate positioning of the anti-vibration hammer and damage to the cable.
