The invention discloses a container ship propeller replacement and installation method, which comprises the following steps that a, a container ship enters a floating dock seat pier, and a barge is stopped at the tail part of a floating dock; b, a reshipment lifting lug is installed on a ship outer plate corresponding to the upper portion of the old propeller; c, mounting a special lifting ring for the propeller above the hub of the old propeller; d, hoists are hung on the reshipment lifting lugs respectively; e, the lower end of the hoist is connected with a special propeller lifting ring through a shackle by using a rope loop; f, dismounting the propeller cap for fixing the old propeller; g, operating a hoist right above the old propeller until the old propeller is loosened from the tail shaft; h, after the old propeller is loosened, the old propeller is in a loose state; i, the old propeller is moved out of the tail shaft; and m, meanwhile, the new propeller is hoisted to the tail of the floating dock, reverse operation is carried out according to the dismantling steps, the new propeller is installed in place, all tools are dismantled, and replacement of the new propeller is completed. The method is scientific, reasonable and safe, and effectively solves the bottleneck of pier repair when a large ship enters a small dock.
本发明公开了一种集装箱船螺旋桨换新安装方法,包括以下步骤:a、集装箱船进浮船坞座墩,在浮船坞尾部停靠驳船;b、在旧螺旋桨上部对应的船外板上安装倒运吊耳;c、在旧螺旋桨桨毂上方安装螺旋桨专用吊环;d、在倒运吊耳上分别挂设葫芦;e、葫芦下端使用绳圈与螺旋桨专用吊环使用卸扣连接;f、拆除固定旧螺旋桨的将军帽;g、操作旧螺旋桨正上方葫芦,直到旧螺旋桨与尾轴松动;h、旧螺旋桨松动后,处于松弛状态;i、将旧螺旋桨从尾轴上移位出来;m、同时将新螺旋桨吊运至浮船坞尾部,按照拆除的步骤进行逆向操作,将新螺旋桨安装到位,拆除所有工具,完成螺旋桨换新。本发明科学、合理、安全,有效解决了大船进小坞的座墩修理的瓶颈。
