Description

Strain drainage wire supports roll adjustment fastener

Technical Field

The invention relates to the technical field of overhead transmission lines, in particular to a strain drainage wire supporting distance-adjusting wire clamp.

Background

The jumper is one of the important components of the overhead transmission line, and is used for connecting the leads on two sides of the tension tower to realize an electric path. During the line construction, the forming of the jumper wire neutron conductor is often not as neat as the conductor of the power transmission line due to the influence of the structural type of the strain tower, the rigidity of the conductor, the relative position of the circuit sub conductor and the like. Due to the sag, the upper drainage wire of the split conductor is easy to collide with the extension pull rod at the rear part of the lower conductor in the construction process, so that the conductor is damaged if the upper drainage wire is light, and the strand of the drainage wire is broken if the upper drainage wire is heavy. Therefore, a set of devices is needed to support the drainage wires and the extension rod and maintain a certain distance, and simultaneously, the requirements of different spatial positions are also needed to be met.

The distance-adjusting wire clip used in the past project is shown in figure 24, and when the distance-adjusting wire clip is used, the wire clip has several problems (1) that the degree of freedom of the wire clip is not enough, and when the plane of the extension pull rod and the plane of the drainage wire are crossed in space, the wire clip needs to bear the action of bending moment, so that the mechanical property of the wire clip is poor; (2) the wire clamp adopts a parallel groove structure type, and the wire clamp cover plate and the wire clamp base adopt the same set of nuts, so that the condition that a wire easily breaks loose from the wire clamp is caused; (3) the rubber pad of centre gripping wire is thin partially, and the back is come loose to the wire, causes the wearing and tearing of rubber even wire because of the vibration easily.
