A high-strength anti-corona pre-twisted suspension clamp

Abstract

The invention relates to a wire suspension hardware tool, in particular to a high-strength anti-corona pre-twisted suspension clamp, which can increase the load-carrying capacity in the vertical direction on the premise of the same material consumption, is easy to install and improves the operating reliability. The high-strength anti-corona pre-twisted suspension clamp comprises a U-shaped wire clamp body and a fastening bolt, wherein the fastening bolt extends from the position of the upper lug plate to the two side edges of the wire clamp body to achieve the purpose of fastening connection; the wire clamp body comprises a first body and a second body, which are oppositely closed; and an installation groove is formed between the first and the second bodies after the two bodies are oppositely closed. The high-strength anti-corona pre-twisted suspension clamp further comprises a first elastic clamping body and a second elastic clamping body which are oppositely closed, and pre-twisted wires, wherein the first elastic clamping body and the second elastic clamping body are semi-circular tile-shaped, and a wire installation groove is formed between the first and the second clamping bodies after the two clamping bodies are oppositely closed, so that the first and the second elastic clamping bodies are clamped on the wires; the pre-twisted wires are wound on the outer surfaces of the first and the second elastic clamping bodies; and the first and the second elastic clamping bodies on which the pre-twisted wires are wound are mounted inside the installation groove. The suspension clamp provided by the invention has higher load-carrying capacity and greatly reduces the material consumption on the premise of the same load-carrying capacity. Besides, the connection is reliable and the resources are saved.

Description

technical field [0001] The invention relates to a wire suspension fitting, in particular to a high-strength halo-proof pre-twisted suspension clamp. Background technique [0002] It is one of the most widely used fittings on the power overhead line of the suspension clamp, and its safety and reliability are of great significance to the safety of power lines and power safety. [0003] At present, in the existing pre-twisted suspension clamps, the clamp body is either hinged or fastened with a U-shaped hoop. When the hinged connection method is adopted, the bottom of the clamp body is generally small because of the small size of the hinged structure clamp, which is often the position where corona is easy to occur; when the U-shaped hoop fastening method is adopted, the left and right sides of the clamp body Parts are only fastened by a U-shaped hoop, and the destructive strength of the clamp is relatively small when the size is the same, or the size is often relatively large ...

AI Technical Summary

Problems solved by technology

When the hinged connection method is adopted, the bottom of the clamp body is generally small because of the small size of the hinged structure clamp, which is often the position where corona is easy to occur; when the U-shaped hoop fastening method is adopted, the left and right sides of the clamp body Some parts are only fastened by a U-shaped hoop. The failure strength of the clamp is relatively small when the size is the same, or the size is often relatively large when the strength is the same, and the material consumption is more, which does not conform to the idea of ​​resource conservation.
