The invention relates to the technical field of propeller strut mechanisms of floating cranes, and provides a propeller strut mechanism of a large floating crane, which is convenient to transfer and is not limited by height, and comprises a ship body, a support frame and a suspension arm mast assembly are mounted at one end of the top of the ship body, and the suspension arm mast assembly is positioned on one side of the support frame; according to the device, the problems that an existing floating crane is inconvenient to move, the height of a propeller strut mechanism cannot be adjusted, and consequently the crane cannot pass through an inland river height limiting bridge are solved, the functionality of the existing floating crane is greatly reduced, and the application range of the existing floating crane is greatly widened. Through the arrangement of the propeller strut mechanism and the variable-amplitude winding system, the ship body drives the whole crane to move on the river surface, and the propeller strut mechanism and the mast can synchronously adjust the height, so that the crane can pass through a lower bridge of an inland river, and the functionality and the application range of an existing floating crane are improved.
本发明适用于涉及浮式起重机人字架机构技术领域,提供了一种便于转运不受高度限制的大型浮式起重机人字架机构,包括船体,所述船体的顶部一端安装有支撑架和吊臂桅杆组件,所述吊臂桅杆组件位于支撑架的一侧,所述吊臂桅杆组件和支撑架之间安装有变幅缠绕系统,该装置解决了现有浮式起重机不便移动以及人字架机构的高度无法调节的问题,从而导致起重机无法通过内河限高桥梁,大大降低了现有浮式起重机的功能性和使用范围,本发明,通过设置人字架机构和变幅缠绕系统,船体带动起重机整体在河面上移动,且人字架机构可与桅杆同步调节高度,致使起重机可通过内河较低矮的桥梁,提高了现有浮式起重机的功能性和使用范围。
