Wire cutter

Abstract

The invention discloses a wire cutter and relates to the field of power system line maintenance. The wire cutter comprises an operating table, the operating table is provided with a rotating device and a retention pressing device corresponding to the position of the rotating device, the retention pressing device comprises a manual opening and closing module fixed on the operating table, the manual opening and closing module is connected with an upper formwork, and a lower formwork bolt is connected to the operating table corresponding to the upper formwork. The rotating device comprises a cylindrical base, the outer portion of the base is sleeved with a bearing, the bearing is sleeved with a turntable, two connecting plates are symmetrically fixed on the circumference of the turntable, one connecting plate is respectively provided with a knife rest with a blade and a feeding device through two first bent plates, the rear end of the knife rest is hinged to the front end of the feeding device, and the other connecting plate is provided with a pressing wheel device relative to the blade. The wire cutter can rapidly cut an aluminum stranded wire of an iron core aluminum stranded wire outer layer and does not damage a steel core, and a broken line part is tidy and attractive.

Description

Technical field [0001] The invention relates to a power system operating equipment, in particular to a tool for cutting wires. Background technique [0002] The transmission line is a power facility that uses insulators and corresponding fittings to suspend the conductors and overhead ground wires on the poles and towers to connect power plants and substations to achieve the purpose of transmitting electrical energy. It is mainly composed of wires, overhead ground wires, insulators, fittings, towers, foundations, and grounding devices. The main function of the wire is to transmit electrical energy. The line conductor should have good electrical conductivity, sufficient mechanical strength, resistance to vibration fatigue and resistance to corrosion by chemical impurities in the air. At present, steel core aluminum stranded wire is often used as the line conductor. When the strain clamp is connected to the conductor, the outer aluminum stranded wire at the end of the steel core...

AI Technical Summary

Problems solved by technology

At present, tools such as pliers, scissors or saws are generally used for stripping the iron core aluminum stranded wire. All the strength is used by the operator based on feeling, which can easily cause the stripping force to be too light to peel it off, or the stripping force cannot Excessive weight causes the layer that does not need to be stripped to be removed, so the occurrence rate of defective products is high; in addition, for the operator, due to the low safety of the tool, improper operation can easily cause personal cuts
