The invention provides a manufacturing and installing method for a semi-suspension type twisted rudder blade of a ship. The manufacturing and installing method comprises the following steps that S1, a rudder blade structure drawing is designed and drawn; s2, the longitudinal grating and the transverse grating in the rudder blade are pre-assembled in an inner field in advance, the grating in the rudder blade serves as a base plane, all the horizontal rib plates are installed, and two independent grating assembly components are formed; s3, manufacturing a rudder blade wrapping plate jig frame template and a rudder blade wrapping plate; s4, a wrapping plate on one side of the rudder blade is positioned; s5, marking a wrapping plate positioning line on the wrapping plate; s6, positioning and mounting the grating assembly component; s7, a rudderstock bearing seat and a rudder pintle bearing seat are installed, and then the grating assembly component and the wrapping plate are welded in an electric welding mode; s8, a wrapping plate on the other side of the rudder blade is installed; s9, stress relief is conducted on the outer surface of the rudder blade; and S10, folding and mounting the rudder blade. According to the manufacturing and mounting method for the semi-suspension type twisted rudder blade, the construction difficulty of the rudder blade can be effectively reduced, the construction precision of the rudder blade is improved, the precision standard of positioning and mounting of a rudder stock during folding is also improved, and the comprehensive cost of later modification is avoided.
本发明提供了一种船舶半悬挂式扭曲舵叶制作安装方法,包括以下步骤:S1.设计绘制舵叶结构图纸;S2.将舵叶内部的纵、横格板在内场提前预装组装,以舵叶内部格板为基面,安装各道水平筋板,形成两个独立的格板组立构件;S3.制作舵叶包板胎架模板和舵叶包板;S4.将舵叶一侧包板定位;S5.在包板上划出包板定位线;S6.格板组立构件定位安装;S7.安装舵杆承座和舵销承座,然后对格板组立构件与包板电焊装焊;S8.舵叶另一侧包板安装;S9.对舵叶外表面进行应力消除;S10.舵叶合拢安装。本发明的半悬挂式扭曲舵叶制作安装方法,该方法能有效降低该舵叶的建造难度,提高自身的建造精度,也提高了合拢时的舵杆定位安装的精度基准,避免后期修改的综合成本。
