Strain drainage wire supporting distance-adjusting wire clamp

Abstract

The invention provides a strain drainage wire supporting distance-adjusting wire clamp. The strain drainage wire supporting distance-adjusting wire clamp comprises two wire clamps, a horizontal elastic connecting piece, an L-shaped connecting rod and a vertical elastic connecting piece, wherein one wire clamp is connected with one end of the horizontal elastic connecting piece; the other wire clamp is connected with one end of the vertical elastic connecting piece; two ends of the L-shaped connecting rod are respectively connected with the other end of the horizontal elastic connecting piece and the other end of the vertical elastic connecting piece; and the two wire clamps are respectively used for clamping the extension pull rod and the drainage wire. According to the structure, multi-degree-of-freedom adjustment between the wire clamps is realized while the space fixing and mounting requirements of the drainage wire and the extension pull rod are met, the wire clamps do not need tobear or bear a very small bending moment effect, and the mechanical property is relatively good.

Description

technical field [0001] The invention relates to the technical field of overhead power transmission lines, in particular to a strain-resistant drainage wire support distance adjustment clamp. Background technique [0002] The jumper is one of the important components of the overhead transmission line. Its function is to connect the wires on both sides of the strain tower to realize the electrical path. During the construction of the line, due to the influence of the structure type of the tension tower, the stiffness of the conductor and the relative position of the sub-conductor of the line, the formation of the sub-conductor of the jumper is often not as neat as that of the transmission line. Due to the existence of sag, the upper drainage wire of the split conductor is likely to collide with the extension rod at the rear of the lower conductor during the construction process, resulting in damage to the conductor in the slightest, and broken strands and disconnection of the ...

Problems solved by technology

[0003] The distance adjustment clamps used in previous projects are as follows: Figure 27 As shown, there are several problems in the use of this type of distance-adjustable cable clamp. (1) The degree of freedom of the cable clamp is not enough. When the plane where the extension rod is located and the plane where the drainage line is located intersect in space, the cable clamp must bear the bending moment , so its mechanical properties are poor; (2) The cable clamp adopts a parallel groove structure, and the cover plate of the cable clamp and the base of the cable clamp use the same set of nuts, which makes it easy for the wire to break free from the cable clamp; (3) The rubber clamping the wire The pad is thin, and after the wire is loose, the rubber or even the wire will be easily worn due to vibration.
