Crane steel wire rope anti-swing system

Abstract

The invention discloses a crane steel wire rope anti-swing system. The crane steel wire rope anti-swing system comprises a motor, a reducer, a brake and a winding drum, which are mounted on a trolley frame and sequentially connected, wherein the lower parts of hoist ropes are twisted on a lower pulley block on an upper sling rack; the crane steel wire rope anti-swing system is characterized in that the eight hoist ropes twisted on the winding drum pass through an upper pulley block and a steering wheel, and steel wire rope lantern rings at the ends of the hoist ropes are respectively connected with piston rods of eight hydraulic cylinders which are symmetrically and uniformly fixed on the four sides of the trolley frame; the eight hydraulic cylinders are divided into two groups; every four hydraulic cylinder blocks are connected in series through hydraulic cylinder connecting pipelines. With the adoption of the technical scheme, the crane steel wire rope anti-swing system disclosed by the invention is simple in structure, the anti-swing effects of the steel wire ropes are obvious, the service life of the steel wire rope is effectively prolonged, and conveniences are brought to routine maintenance and repair of the equipment; the steel wire ropes are twisted in a multi-magnification manner, and the magnification factor is two, so that the pull of the steel wire ropes is only half of that in the prior art, and the torque of the winding drum can be reduced. Therefore, the specification of the reducer can be reduced, and the manufacturing cost can be lowered.

Description

technical field [0001] The invention is applicable to various container cranes and other lifting equipment with similar container spreaders. Background technique [0002] When handling containers, in order to facilitate the driver's operation and improve work efficiency, users have anti-sway requirements for the spreaders of container gantry cranes. Different wire rope winding systems have different anti-sway effects. ZL03117018.8 proposes a two-way anti-sway system for cranes. The patented 8-rope winding method, when applied to a large container crane, the force on the wire rope is large, the torque of the reducer is large, and the force on the 8 wire ropes is unbalanced, resulting in a short life of the wire rope. . The end of the wire rope is fixed on the hanger, which is not convenient for daily maintenance. At the same time, there is no specific implementation method when the multi-rate winding method of the wire rope is missing. Contents of the invention [0003] I...
