Anti-rolling winding device and tire type container gantry crane

Abstract

The invention provides an anti-rolling winding device and a tire type container gantry crane, and relates to the technical field of crane rolling prevention. The anti-rolling winding device comprisesa first unwinding mechanism and a plurality of anti-rolling units, wherein each anti-rolling unit comprises a first rope body, a pulley assembly used for being installed on a lifting appliance and a second unwinding mechanism used for being installed on a trolley; one end of each first rope body is connected with the first unwinding mechanism, and the other end of each first rope body penetrates through the corresponding pulley assembly to be connected with the corresponding second unwinding mechanism; and in the moving direction of the trolley and the moving direction of a cart, an inverted triangular structure is defined by the extending path of each first rope body and the trolley. According to the anti-rolling winding device, the abrasion of the first rope bodies is relieved, the lifting structure is more stable, and the anti-rolling effect is better.

Description

technical field [0001] The invention relates to the technical field of anti-sway cranes, in particular to an anti-sway winding device and a tire-type container gantry crane. Background technique [0002] When the spreader on the gantry crane is lifting the container, the trolley will walk along the trolley track on the main girder of the gantry crane, and the trolley will walk along the laid trolley track. The trolley and the trolley drive the spreader along the X direction and The movement in the Y direction will cause the sling to sway to a certain extent during the hoisting process, and it is necessary to reduce the sway of the sling through the anti-sway structure. [0003] At present, in the existing anti-sway structure of the gantry crane, either the steel wire rope is fixedly connected with the spreader, or the steel wire rope is suspended on the pulley on the spreader, and the effect of lifting and anti-sway is realized by adjusting the length of the steel wire rope....

AI Technical Summary

Problems solved by technology

However, in the first method, the steel wire rope is subjected to a large force, and the damage degree of the steel wire rope needs to be checked frequently; in the second method, the path that the steel wire rope passes before entering the pulley is usually parallel to the path that the wire rope passes after extending out of the pulley, resulting in The hoisting structure is unstable, and the stability is still poor during the container hoisting process
