Damping-variable steel wire rope torsional force release device

Abstract

The invention discloses a damping-variable steel wire rope torsional force release device. The damping-variable steel wire rope torsional force release device comprises an upper cavity housing, a lower cavity housing, an upper cavity and lower cavity connecting assembly and a damping adjusting mechanism, wherein the upper cavity housing and the lower cavity housing are cylindrical, arranged oppositely up and down, connected with each other through the upper cavity and lower cavity connecting assembly, and used for being connected with ends of a steel wire rope; and the damping adjusting mechanism is installed in the upper cavity housing and located between the upper cavity and lower cavity connecting assembly and the upper cavity housing, and used for adjusting the rotation speed when the torsional force of the steel wire rope is released. The damping-variable steel wire rope torsional force release device can be directly installed on the steel wire rope, and can release the torsional action force generated by the rope in the operation process stably in time, the operation is simple, easy to implement and reliable, the defect that the torsional action force of the rope cannot be released or is released too fast in the working process to cause reverse breaking is overcome, the problem of the poor working condition of the rope is solved, the service life of the rope is prolonged, and the using safety of the rope is improved.

Description

technical field [0001] The invention relates to the technical field of crane hanger connections, in particular to a variable damping wire rope torsional force release device. Background technique [0002] As an important part of crane hook and spreader connection, the wire rope torsional force release device is widely used in hoisting machinery, which can release the torsional force of the wire rope during work in time. The wire rope torsion force release device is used in conjunction with the wire rope, and is mainly used to release the torque generated by the wire rope during use, to prevent the wire rope from being hinged and entangled, and to prevent the wire rope from breaking due to the increase in torque. However, at the present stage, during the use of the steel wire rope, the torsional force of the steel wire rope cannot be released during the working process, or some devices can be used to release but the release speed is too fast, resulting in reverse rotation due...

Problems solved by technology

However, at the present stage, during the use of the steel wire rope, the torsional force of the steel wire rope cannot be released during the working process, or some devices can be used to release but the release speed is too fast, resulting in reverse rotation due to inertia after release, thus forming The dismantling and torsional force of the reverse rope strands greatly reduces the life and mechanical properties of the rope, and more accidents of wire rope damage occur, posing a great safety hazard
