The invention discloses a floating crane ship propeller overturning and hoisting structure and a method for installing a propeller, and relates to the technical field of ship construction. The floating crane ship propeller overturning and hoisting structure comprises a lifting lug set arranged on a ship body block and a lifting hole set arranged on the propeller; the number of the lifting lug sets is five, each lifting lug set comprises two lifting lugs, and the two lifting lugs are symmetrically arranged along the section in the length direction of the ship with respect to the central axis of the propeller well. The number of the lifting hole sets is three, each lifting hole set comprises two lifting holes, the first lifting hole set and the second lifting hole set are formed in the face, located on the inner side of a cabin, of the installation flange, and the two lifting holes of the first lifting hole set and the two lifting holes of the second lifting hole set are located in the same circle with the circle center of a center hole of the installation flange as the circle center. Lifting ropes are arranged between the lifting lug sets and the corresponding lifting hole sets, and the lifting ropes can be tightened or loosened. By arranging a reasonable hoisting structure, each state of the propeller in the overturning installation process is controllable, finally, the propeller is adjusted to the installation position, the posture is controllable, and therefore precise positioning and precise installation of the propeller are achieved.
本发明公开了一种浮吊船推进器翻转吊装结构及安装推进器的方法,涉及船舶建造技术领域,包括设置在船体总段上的吊耳组和设置在推进器上的吊孔组;吊耳组设置有五组,每组包括两个吊耳,两个所述吊耳以推进器井中轴线沿船长方向剖面对称布置;吊孔组设置有三组,每组包括两个吊孔,其中第一吊孔组和第二吊孔组设置在安装法兰上位于船舱内侧的一面上,第一吊孔组的两吊孔和第二吊孔组的两吊孔位于同一以安装法兰中心孔的圆心为圆心的圆上;吊耳组与其对应的吊孔组之间设置有吊绳,吊绳可收紧或放松。通过设置合理的吊装结构,实现推进器翻转安装过程中各个状态的可控,最终将推进器调整至安装位置且姿态可控,从而实现推进器精确定位和精准安装。
