Description

Anti-torsion device for steel wire rope Technical Field The utility model relates to the technical field of anti-torsion devices, in particular to an anti-torsion device for a steel wire rope. Background The steel wire rope is a spiral steel wire bundle which is formed by twisting steel wires with mechanical properties and geometric dimensions according to certain rules, and is used for lifting, traction, tensioning and bearing in a material handling machine. Because the spiral structure of the steel wire rope enables the steel wire rope to generate interaction internal force between each layer of steel wires and the strand rope when the steel wire rope is stressed, in hoisting operation, when the steel wire rope is acted by tensile force, the internal force can be decomposed into axial component force parallel to the axis of the steel wire rope and radial component force perpendicular to the axis of the steel wire rope, the radial component force can lead the strand or the steel wire rope to generate torsion trend, and the end head of the steel wire rope is usually fixed during hoisting, the free rotation of the steel wire rope is limited by the fixing mode, so that internal torque cannot be released, torsion phenomenon is further aggravated, the steel wire rope is seriously distorted, and cracks, fracture and the like appear, and the service life and safety of the steel wire rope are influenced.
