Crimping device for steel-cored aluminum stranded wire

Abstract

The invention discloses a crimping device for a steel-cored aluminum stranded wire. The crimping device comprises a first mounting ring, a second mounting ring arranged at a lower part of the first mounting ring, and sliding rods symmetrically arranged on one side of the first mounting ring and one side of the second mounting ring, and a crimping cylinder is clamped between the first mounting ringand the second mounting ring; a sliding block is arranged on each sliding rod, a clamping hook is arranged on one side of the sliding block, and a connecting buckle is arranged at one end of a pressing rod; and a first clamping ring is arranged at the lower end of the upper sliding block, a second clamping ring is arranged at the upper end of the lower sliding block, a connecting device is arranged between a first grip and a second grip, and a stranded wire body is arranged between the first clamping ring and the second clamping ring. In the invention, the crimping cylinder is clamped in thefirst mounting ring and the second mounting ring; and the sliding rods are arranged on one side of the first mounting ring and one side of the second mounting ring, the sliding block is arranged on each sliding rod, the pressing rod is arranged on the upper portion of the sliding rod, the pressing rod is used for pushing the sliding block, the stranded wire body is pushed into the crimping cylinder step by step, stress uniformity of the stranded wire body is guaranteed, and technical difficulty of construction personnel is reduced.

Description

technical field [0001] The invention belongs to the technical field of cable crimping, in particular to a crimping device for aluminum-steel-cored wires. Background technique [0002] Steel-cored aluminum stranded wire is made of aluminum wire and steel wire, which is suitable for overhead transmission lines. It has a steel "core" inside, and aluminum wires are wound around the steel core by twisting on the outside; the steel core It mainly plays the role of increasing the strength. The aluminum stranded wire mainly plays the role of transmitting electric energy. During the crimping operation, one end of the stranded wire needs to be inserted into the crimping tube and crimped to complete the connection and use, which is convenient for multi-wire connection or protective installation of the joint. . [0003] After retrieval, the Chinese patent authorization number is CN201320769786.4, which discloses a crimping device for aluminum-steel conductors for power conductor constr...

AI Technical Summary

Problems solved by technology

A kind of crimping device for aluminum steel-cored wire for power conductor construction in the above-mentioned patent has the following disadvantages: when plugging inward, it needs to be manually pushed for insertion, and uneven force may cause certain bending and irregular pushing of the twisted wire, and It is laborious to push manually, which has a certain impact on the continuous installation operation of multiple lines
