Abstract

The invention relates to the technical field of port handling, in particular to a sling torsion proof device, a lifting winding system, and a port crane. The sling torsion proof device includes driving assemblies, transmission assemblies, and fixing assemblies, the fixing assemblies are arranged on the transmission assemblies and are used to fix steel wire rope assemblies connected with a sling, the driving assemblies can drive the transmission assemblies to translate to and fro along a first direction so that the fixing assemblies pull the steel wire rope assemblies to and fro along the firstdirection, the lifting winding system includes the sling torsion proof device, and the port crane includes the lifting winding system. According to the sling torsion proof device, the lifting windingsystem, and the port crane, the torsion of the sling need not to be restored manually by operating personnel, the sling can rotate quickly and reach the tank aligning position, the manpower is savedand the tank aligning efficiency is improved, so that the handling efficiency of a shore bridge can be improved, the inertia torsion of the sling can be eliminated, the occurrence of an accident of tank colliding is prevented, and the sling is prevented from torsion intensification.

Description

technical field [0001] The invention relates to the technical field of port loading and unloading, in particular to an anti-twist device for a spreader, a lifting winding system and a port crane. Background technique [0002] The port crane usually lifts the quay bridge and loads and unloads the container by lifting the spreader. Since the quay bridge is raised, a longer wire rope is required for lifting operations, so it is easy to cause the wire rope to swing or twist during the process of pulling the wire rope. And then cause the spreader below the steel wire rope to twist or tilt due to inertia, which brings difficulties to the box alignment with the container. [0003] In the related technology, the twisting of the spreader is usually restored manually. This manual twisting method is inefficient, labor-intensive and depends on the work experience of the personnel. Improper operation is not ideal for the recovery of the twisting of the spreader, and it is even easy to re...
