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 at the same time, the requirements of different spatial positions are also met.

As shown in fig. 21, a distance-adjusting wire clip used in the conventional art includes: the cable clamp comprises a cable clamp cover plate 6, cable clamp rubber 7, a cable clamp base 8, a nut 9 and a stud bolt 10; when using, the distance-adjusting wire clamp has several problems:

(1) the freedom degree of the wire clamp is not enough, and when the plane of the extension pull rod is vertical to the plane of the drainage wire in space, the wire clamp needs to bear the action of bending moment, so the mechanical property of the wire clamp 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.

Disclosure of Invention

Aiming at the defects of the prior art, the invention designs the strain drainage wire supporting distance-adjusting wire clamp which is suitable for the size requirements of extension pull rods and wires of various overhead transmission lines and realizes multi-degree-of-freedom adjustment between the wire clamps. The wire clamp adopts the hinge form, has realized independent clamping wire and extension pull rod. Meanwhile, the rubber pad of the wire clamp is thickened, so that the abrasion of the wire is avoided. The multi-freedom-degree adjusting device is provided for adjusting multiple degrees of freedom between wire clamps and independently clamping the wires and extending the pull rods, and line faults caused by collision of the wires and the extension pull rods are avoided.
