The invention provides an out-of-cabin hoisting device and method for a tail shaft of a large ship, and relates to the technical field of ship hoisting. The hoisting device comprises a portal crane, a first pneumatic hoist, a second pneumatic hoist, a third pneumatic hoist, a protective round pipe and a limiting tool, the invention further provides a large ship stern shaft out-of-cabin hoisting method, auxiliary holes are formed in a ship, the ship stern shaft is hoisted through the large hoisting device, and after the bow portion of the ship stern shaft is higher than the stern portion, the ship stern shaft is hoisted through the protective round pipe. The portal crane is used for slowly lifting the bow of the ship stern shaft and gradually moving towards the bow, a middle bearing support of a ship body is prevented from being touched in the moving process, and after the portal crane is stably stressed, the horizontal projection length of the ship stern shaft is adjusted to be smaller than the length of an auxiliary hole through the pneumatic hoist, and then the ship stern shaft is hoisted out of a cabin through the portal crane. According to the invention, horizontal hoisting of the stern shaft out of the cabin is changed into large-angle hoisting of the stern shaft out of the cabin, so that the task load and the construction cost of hoisting are reduced, and rapid hoisting of the large ship stern shaft out of the cabin is realized.

    本发明提供了一种大型船舶艉轴出舱吊运装置及方法,涉及船舶吊装技术领域。本发明吊运装置包括门机、第一风动葫芦、第二风动葫芦、第三风动葫芦、防护圆管和限位工装,本发明还配套提出了大型船舶艉轴出舱吊运方法,通过在船舶上开设工艺孔,利用大吊运装置将船舶艉轴吊起,使得船舶艉轴的艏部高于艉部后,利用门机将船舶艉轴的艏部缓慢抬起并逐渐向艏部移动,移动过程避免触碰船体中间轴承支架,待门机受力稳定,利用风动葫芦将船舶艉轴的水平投影长度调整至小于工艺孔的长度后,利用门机将船舶艉轴吊运出舱。本发明通过将平吊艉轴出舱变为大角度吊装艉轴出舱,降低了吊运的任务量和施工成本,实现了大型船舶艉轴的快速吊运出舱。
