Portable LGJ-aluminum cable steel reinforced positioning holder

Abstract

The invention discloses a portable LGJ-aluminum cable steel reinforced positioning holder, and belongs to the technical field of power construction equipment. The device comprises two petal semi-annular positioning mode buckles which are hinged by a hinge shaft, wherein connection seats are respectively arranged at free ends of the positioning mode buckles, the two connection seats are fastened toform a whole by a fastening piece, semi-annular positioning modes are respectively fixed in the positioning mode buckles, the radius of an outer side surface of each positioning mode is equal to theradius of an inner side surface of each positioning mode buckle, the radius of an inner side surface of each positioning mode is equal to the radius of a steel core aluminum stranded wire, ends of thepositioning modes protrude out of the positioning mode buckles, and one of the positioning modes is used for fixing a groove of a turntable-type cuter cam. When a turntable-type cutter is used for cutting an outer-layer aluminum wire of the steel core aluminum stranded wire in a rotation way, the aluminum wire of a cross section of the end of the aluminum stranded wire of the positioning holder can be enabled not to be scattered, smooth twisting texture of the original wire is maintained, burr and crimping are prevented, the positioning holder is accurate and convenient to operate, and the construction quality is ensured.

Description

technical field [0001] The invention belongs to the technical field of electric power construction equipment, in particular to a portable LGJ-steel-cored aluminum strand positioning gripper. Background technique [0002] In the installation of 35kV-500kV high-voltage transmission line conductors and electrical primary equipment, it is necessary to connect LGJ-steel-reinforced aluminum stranded wire and tension clamps, connecting pipes, equipment clamps and other connecting fittings. LGJ-steel-reinforced aluminum stranded wires are wrapped with two Layer aluminum wire, inside is galvanized steel wire core wire. According to the construction requirements, when two steel-reinforced aluminum stranded wires are butt-connected, the outer aluminum wires of the two wire ends must first be stripped off, and then the ends of the galvanized steel core wires are inserted into the connecting steel pipe for crimping. Tension, and finally put an aluminum tube on the outside of the wire fo...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, a portable LGJ-steel-reinforced aluminum wire stripper is used to strip the outer layer of aluminum wire. When the outer aluminum wire of the stranded wire is rotated and cut down, the aluminum wire will be loose, which will destroy the original wire twisted pattern and make it difficult to pass through the pipe.

2. When the rotary disc cutter rotates and cuts the outer aluminum wire of the steel core aluminum stranded wire, the displacement occurs, causing the incision to be inclined, and the parameters of the aluminum wire are not uniform.

3. When the turntable cutter rotates and cuts the outer aluminum wire of the steel-reinforced aluminum strand, it causes burrs or curls at the end of the aluminum wire. These burrs or curls rub against the inner wall of the tube when they pass through the tube, resulting in scratches and embedded in the tube. In severe cases, the ends of the steel-reinforced aluminum stranded wires will be stuck in the pipe, making it impossible to advance or retreat.

The stuck tube not only increases the workload, but also causes rough crimping of the aluminum wire series tubes of the tension clamps, connecting tubes, and equipment clamps, which will cause overcurrent and voltage drop control abnormalities, increase the resistance and cause overheating, and may also cause damage to the crimping tubes
