Problems solved by technology

The tension clamps connect the shell body (clamp shell) to the electric tower through a pull rod or a hanging plate, which requires considerable strength. Most of the main tubes of the existing clamp shells are single-layer main tubes, which are not very good. Satisfies the harsh conditions of use of tension clamps

Abstract

The invention discloses a tension clamp, which comprises a tension clamp housing, a drainage plate, and a drainage clamp. The drainage plate is fixed on a main pipe, the drainage clamp and the drainage plate are connected by bolts, and a wedge-shaped groove is arranged on the drainage plate. , the wedge-shaped plate on the drainage clamp is sleeved in it, the tension clamp housing includes a main pipe and a steel anchor, the main pipe is a hollow structure, one end of the main pipe is fixedly connected with a steel anchor, and the other end of the main pipe is provided with a second A lined aluminum pipe, a second lined aluminum pipe, and reinforced steel pipe. The main tube of the hollow structure is equipped with the first lined aluminum tube, the second lined aluminum tube, and the reinforced steel tube to ensure the strength of the main tube and make it better adapt to harsh service conditions. The drainage plate is designed with wedge-shaped grooves. Used in conjunction with the wedge-shaped drainage clip, when the drainage clip moves down, the wedge-shaped structure makes the cooperation between the drainage plate and the drainage clip tighter and tighter, even when the fixing bolts are loose, the C-shaped groove makes it difficult for the drainage plate to come off.

Description

technical field [0001] The invention relates to the field of wire clips, in particular to a strain-resistant wire clip. Background technique [0002] With the rapid development of power application facilities in power distribution networks, in high-voltage and ultra-high-voltage overhead power systems, in order to anchor and tighten both ends of carbon fiber composite core conductors to poles or towers, strain clamps are required. The tension clamps connect the shell body (clamp shell) to the electric tower through a pull rod or a hanging plate, which requires considerable strength. Most of the main tubes of the existing clamp shells are single-layer main tubes, which are not very good. It can meet the harsh conditions of use of tension clamps. Contents of the invention [0003] The purpose of the present invention is to provide a tension clamp to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the pr...
