Description
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. 24, a distance-adjusting wire clip used in the conventional engineering includes: the cable clamp comprises a cable clamp cover plate 7, cable clamp rubber 8, a cable clamp base 9, a nut 10 and a stud bolt 11; when using, the distance-adjusting wire clamp has several problems:
(1) the freedom degree of the wire clamp is not enough, and when the distance between the extension pull rod and the drainage wire is far, the wire clamp needs to bear not only larger pulling force but also bending moment, so that the mechanical property is poor, and the wire is easy to damage;
(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.
