The invention relates to the field of ship maintenance, and discloses a ship and a ship propeller shaft replacement method. The ship comprises a rudder system and a propulsion system, wherein the rudder system comprises a rudder blade, a through hole is formed in the rudder blade, and sealing plates are detachably connected to the two ends of the through hole respectively; and the propulsion system comprises a propeller shaft, the tail end of the propeller shaft is connected with a propeller and faces the rudder blade, when the propeller shaft is detached, the rudder blade rotates to a presetrudder angle, and the propeller shaft can move in the axis direction of the propeller shaft and penetrate through the through hole. When the propeller shaft of the ship is replaced by a new propellershaft, the rudder blade rotates to the preset rudder angle, the propeller shaft can move in the axis direction of the propeller shaft and penetrate through the through hole, the complex operation of disassembling the rudder system before disassembling the propeller shaft is avoided, the workload and the working difficulty of the propeller shaft maintenance personnel are reduced, the working time is shortened, the safety is improved, and then the maintenance cost of the ship propeller shaft is reduced.
本发明涉及船舶维护领域,公开了一种船舶和船舶螺旋桨轴的换新方法。一种船舶包括舵系和推进系统。舵系包括舵叶,舵叶开设有通孔,通孔的两端分别可拆卸连接有封板。推进系统包括螺旋桨轴,螺旋桨轴的尾端连接有螺旋桨并朝向舵叶,当拆卸螺旋桨轴时,使舵叶转动至预设舵角,螺旋桨轴能够沿自身轴线方向移动并穿过通孔。本发明的船舶在换新螺旋桨轴时,舵叶转动至预设舵角,螺旋桨轴能够沿自身轴线方向移动并穿过通孔,避免了拆除螺旋桨轴前拆除舵系的复杂操作,降低了螺旋桨轴维护人员的工作量和工作难度,缩短了工作时间,提高了安全性,进而降低了船舶螺旋桨轴的维护成本。
