The invention discloses a crane anti-sway device and its control method and the crane, which comprises a trolley frame, a hanger and an anti-sway device. Translating device and second translating device, the first movable pulley and the second movable pulley respectively fixed on the two translating devices, the fixed pulley installed on the spreader, the first anti-sway wire rope and the second anti-sway wire rope; two anti-sway The steel wire rope is wound on the reel, extending from the opposite sides of the reel, passing around the movable pulley and the fixed pulley in turn, and then fixed on the trolley frame; the anti-sway controller controls the first translation device and the second translation device to move relatively or oppositely, To adjust the distance between the first translation device and the second translation device; if the spreader is twisted during operation, the horizontal distribution of the anti-sway wire rope in the twist direction can be changed by adjusting the translation device in the anti-sway device in the twist direction. The active anti-sway effect of the spreader is realized based on the horizontal component force.
Description
technical field [0001] The invention belongs to the technical field of hoisting equipment, and in particular relates to a crane anti-sway device, a control method thereof and a crane. Background technique [0002] In recent years, with the rapid development of container logistics, large ships have become the main ship types of the world's ocean trunk lines. The large-scale ship puts forward higher requirements on the loading and unloading efficiency of the port. [0003] At present, there is still a big gap between the loading and unloading efficiency of ports in various countries and the efficiency requirements of ships, and the main bottleneck restricting the operation efficiency is the loading and unloading of the main spreader of the bridge crane with the most complicated working conditions. The current design capacity of the bridge crane is about 45-50 natural containers per hour, while the actual average operating efficiency of the port is 28-30 natural containers. Th...
