The invention relates to the technical field of in-dock blade fitting, and particularly discloses a large floating dock blade fitting process, which is characterized in that an old propeller is lifted out from a tail shaft to a position between the tail shaft and a rudder through a hoist crane handover mode, and then the old propeller is lifted to a position, convenient for a floating crane to lift, on the side of a starboard through the hoist crane handover mode; an old propeller is helped to turn over through a hoist crane and a floating crane, the floating crane is used for adjusting the old propeller away from a working area, a new blade hub and an original stern shaft cone area are checked and measured, the taper hole fitting allowance of the new blade hub is confirmed, new blades are hoisted through the floating crane and the hoist crane, and horizontal fitting in a dock is achieved through a new fitting process. And therefore, the traditional fitting process flow is simplified, and the fitting precision is improved.
本发明涉及坞内桨叶拂配技术领域,具体公开了大型浮船坞内桨叶拂配工艺,过起重葫芦交接的方式将老旧螺旋桨从艉轴吊出,至艉轴与舵之间,再次通过起重葫芦交接的方式将老旧螺旋桨吊到右舷舷侧方便浮吊吊运的位置,通过起重葫芦和浮吊帮助老旧螺旋桨翻身,用浮吊将老旧螺旋桨调离工作区域,检查和测量新桨叶桨毂和原船艉轴锥体区域,确认新桨叶桨毂锥孔拂配余量,通过浮吊和起重葫芦起吊新的新桨叶通过新的拂配工艺实现坞内水平拂配,进而简化传统的拂配工艺流程,提高拂配精度。
