AI Technical Summary

Technical Problem

In existing technologies, the wire rope winding method can easily lead to uneven wire rope length during ultra-high lifting, causing the lifting device to tilt and twist, which affects the stability and safety of the lifting process.

Method used

The steel wire rope is wound in multiple layers. The main lifting mechanism and the auxiliary lifting mechanism, combined with the balance pulley and balance arm, adjust the uneven length of the steel wire rope and release the torque through the anti-rotation sleeve to achieve the balance and torsion compensation of the rope.

Benefits of technology

It effectively solved the problems of uneven wire rope length and torsion, improved the stability and safety of the lifting process, and reduced the risk of skewing and torsion of the lifting equipment.

Abstract

The utility model relates to the technical field of steel wire rope winding error compensation, in particular to a steel wire rope multi-layer winding crane positioning error compensation device which comprises a lifting part and a lifting balance group, the lifting part comprises a lifting steel wire rope group; the lifting balance group is used for keeping the balance of a rope body included in the lifting part in the use process, and comprises a balance pulley and a balance arm; the lifting steel wire rope set comprises a main lifting mechanism and an auxiliary lifting mechanism. Based on the structural arrangement, the problems that the winding length of the steel wire rope is unbalanced, the steel wire rope is difficult to adjust and the rope body is twisted due to the manufacturing error of the winding drum and the extension and extension of the steel wire rope in the current ultrahigh-lift lifting process can be solved, and the stability, the balance and the safety in the lifting process are improved.
