Crane bothway anti-swing mechanism and crane

Abstract

The invention provides a crane bothway anti-swing mechanism and a crane. The crane bothway anti-swing mechanism comprises a trolley support, a hoisting tool upper support and a coiling block; the coiling block is arranged on the trolley support; a first-direction anti-swing assembly is further included and comprises a first steel wire rope, a first upper support sliding wheel arranged on the hoisting tool upper support, a winding-out assembly and a first winding-back assembly, and the winding-out assembly and the first winding-back assembly are evenly arranged on the trolley support; the firstend of the first steel wire rope is connected with the coiling block, and the second end of the first steel wire rope is wound out from the coiling block to pass through the winding-out assembly, thefirst upper support sliding wheel and the first winding-back assembly to form an inverted triangle shape.

Description

technical field [0001] The invention relates to the field of hoisting machinery, in particular to a two-way anti-sway mechanism for a crane and the crane. Background technique [0002] The main hoisting wire rope winding method of the traditional container gantry crane cannot restrain the swing of the container spreader and the container in the traveling direction of the trolley and the traveling direction of the cart, so a mechanical, hydraulic or electronic anti-sway system must be added to restrain the swing of the container crane. swing of tools and containers in the direction of travel of the trolley and / or the direction of travel of the cart. In the prior art, the container spreader and the container anti-sway mechanism mostly adopt mechanical anti-sway and electronic anti-sway. Among them, mechanical anti-sway mostly adopts torque motor anti-sway, 4-rope one-way anti-sway and 8-rope two-way anti-sway, mechanical anti-sway is mostly active anti-sway; electronic anti-s...

Problems solved by technology

[0005] However, the above-mentioned 4-rope anti-sway mechanism has the following technical defects: first, the four-rope winding only forms an inverted triangle in two planes, and the angle between the two isosceles of the inverted triangle is too small, so the anti-sway effect is poor; Four-rope winding cannot achieve anti-sway in the running direction of the cart; third, four-rope winding needs to be used together with torque motor anti-sway or electronic anti-sway to increase the anti-sway effect in the direction of trolley movement, but the cost of anti-sway is high

[0006] The above-mentioned 8-rope two-way anti-sway mechanism has the following technical defects: first, the wire rope is wound at a single rate, and the torque generated by the self-weight of the cargo all acts on the reducer, which has a large model and high cost; second, the length of the wire rope is adjusted by adjusting the bolt , the adjustment is difficult and the adjustment effect cannot meet the target requirements; third, the steel wire rope is not uniformly stressed, so that the life of the steel wire rope is short, and often some of the 8 steel wire ropes reach the scrapping standard early, while the rest of the steel wires have not yet reached the scrapping standard , resulting in waste of cost

[0007] In summary, the existing anti-sway mechanism has the problems of poor anti-sway effect, high anti-sway cost and short anti-sway life
