Abstract

The invention relates to a self-balancing windproof stay rope device of a heavy crane in a port, mainly comprising a winding drum (8) and two sets of stay ropes with the same structures, wherein each set of the stay rope is composed of a spiral buckle (4), a steel wire rope (7) and a fixing pin shaft; the spiral buckle is located between a crane windproof stay rope ear plate (1) and the steel wire rope; the upper end of the spiral buckle is fixed with the crane windproof stay rope ear plate via an ear plate fixing pin shaft (2); the lower end of the spiral buckle is connected with the upper part of the steel wire rope via the fixing pin shaft of the steel wire rope; the lower parts of the two sets of stay rope steel wire ropes are wound on the winding drum (8) in reversed directions; the winding tail end of the steel wire rope is fixed on the winding drum by a steel wire rope pressing plate (12); the winding drum is fixed and supported by two winding drum supporting seats; and each supporting seat is fixed with a wharf embedded part (10) via bolts. When typhoon or hurricane comes, the device provided by the invention can notably improve the windproof ability and the windproof safety of the heavy crane in port; furthermore, the device is convenient in use and is capable of prolonging the service life of the stay rope.

Description

technical field

[0001] The invention relates to a windproof device for a large port crane, in particular to a self-balancing windproof cable device for a large port crane. Background technique

[0002] In order to adapt to the large-scale development trend of freight ships and improve their loading and unloading efficiency, port cranes are also constantly developing in the direction of large-scale, and the large-scale cranes also increase their center of gravity, increase the windward area, and the possibility of suffering from wind disasters. Increase. In recent years, typhoons or hurricanes have caused frequent wind disaster accidents on large cranes in ports. Once an accident occurs, it will not only directly affect the production order of the terminal, but also cause major economic losses to related enterprises, and even cause casualties.

[0003] At present, the anti-typhoon and anti-hurricane devices of large port cranes mainly include rail clamps, anchors (hooks), wh...
