Roll stabilization system for crane sling and operation method thereof

Abstract

The invention discloses a roll stabilization system for a crane sling. The roll stabilization system comprises a plurality of fans (1) and a fan control system, wherein the fans (1) are separately positioned at the four opposite corners of the crane sling (2) and are symmetrical about the center of the sling (2); air openings of the fans (1) face the sling (2); and the fan control system controls the fans (1) to act on the sling (2). The invention further provides an operation method of the roll stabilization system for the crane sling. According to the roll stabilization system, the roll stabilization effect is achieved through the fans and the simple fan control system, structure is simple, cost is low, and later maintenance is simple; torsion and changing resistance of the sling is directly increased through reverse thrust generated by the fans, so that the roll stabilization system is safe and reliable, and the roll stabilization effect is good; and quick alignment of the sling can be achieved, and assembly and disassembly efficiency is improved.

Description

technical field [0001] The invention relates to the field of port hoisting machinery, in particular to a crane spreader anti-sway system and an operating method thereof. Background technique [0002] The existing anti-rolling systems mainly include the following types: [0003] 1. Rigid guide cylinder braking and anti-rolling system: The guide cylinder is installed above the spreader, and the guide cylinder rolls or slides in the outer cylinder and frame connected to the trolley frame. It can effectively prevent the sway of the spreader and the load due to the horizontal force. [0004] 2. Separation trolley type anti-rolling system: By separating the front and rear hoisting trolleys for a certain distance, the suspension steel wire rope forms an inverted triangle and generates horizontal force components to achieve the purpose of anti-rolling. [0005] 3. Hydraulic anti-sway system: Use hydraulic cylinders to increase system damping and control existing swings [0006] 4...

AI Technical Summary

Problems solved by technology

[0009] However, the rigid guide cylinder braking type has a complex structure and high cost, and is mainly suitable for occasions with low lifting height; the separation trolley type has a complex structure, troublesome maintenance and debugging, and the anti-sway effect is general; the hydraulic anti-sway system and auxiliary wire rope The structure of the anti-rolling system is complicated, the cost is high, and the maintenance and debugging are troublesome; the winding of the wire rope of the inverted triangle eight-rope anti-rolling system is complicated, the wear of the steel wire rope increases, and the service life decreases; Decreased effect
