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 strain clamp shell and a strain clamp comprising same. The strain clamp shell comprises a main body pipe and a steel anchor, the main body pipe is of a hollow structure, one end of the main body pipe is fixedly connected with the steel anchor, and a first lining aluminum pipe, a second lining aluminum pipe and a reinforcing steel pipe are arranged in the other end of the main body pipe; the strain clamp comprises the strain clamp shell, a drainage plate and a drainage wire clamp, the drainage plate is fixed on the main body pipe, the drainage wire clamp is connected with the drainage plate through a bolt, a wedge-shaped groove is formed in the drainage plate, and the wedge-shaped plate on the drainage wire clamp is sleeved in the wedge-shaped groove. The first lining aluminum pipe, the second lining aluminum pipe and the reinforcing steel pipe are arranged in the main body pipe of the hollow structure, the strength of the main body pipe is guaranteed, the main body pipe can better adapt to harsh using conditions, the drainage plate is provided with the wedge-shaped groove and is used in cooperation with the wedge-shaped drainage wire clamp, and when the drainage wire clamp moves downwards, the wedge-shaped structure enables the drainage plate and the drainage wire clamp to be matched tighter and tighter, and even if the fixing bolt is loosened, the C-shaped groove enables the drainage plate not to be separated easily.

Description

technical field [0001] The invention relates to the field of wire clips, in particular to a tensile wire clip casing and a tensile wire clip containing the same. Background technique [0002] With the rapid development of power application facilities in distribution networks, in high-voltage and ultra-high-voltage overhead power systems, in order to anchor and tension both ends of carbon fiber composite core wires to poles or towers, tension clamps are required. The tension clamps connect the shell body (clamp shell) to the electrical tower through tie rods or hanging plates, which requires considerable strength. It can meet the strict conditions of use of tension clamps. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a tension clamp housing and a tension clamp containing the same, so as to solve the problems raised in the above-mentioned background art. [0004] In order to achieve the above purpose, the present invention provides t...
