本公开涉及一种半船起浮艉轴密封工装及密封方法,包括密封板、环形密封垫片、螺栓结构,在艉轴的外端面和内端面分别设置一块密封板,在外端的密封板上固定安装螺柱,在外端和内端的密封板上均设置环形密封垫片,将螺柱穿过艉轴孔,并将外端的密封板通过对应环形密封垫片与艉轴的外端面贴紧,将内端的密封板通过对应环形密封垫片与艉轴的内端面贴紧,将螺柱的内端与内端的密封板固定,并通过螺柱拉紧两端的密封板,使得两端的密封板通过对应的环形密封垫片压紧对应的端面,实现密封。拆装方便,还可以重复多次使用,密封性好,对艉轴无损害。

    The invention relates to a sealing tool and a sealing method for a floating tail shaft of a semi-ship. The sealing tool comprises sealing plates, annular sealing gaskets and a bolt structure. The sealing plates are separately arranged on the outer end surface and the inner end surface of the tail shaft, a stud is fixedly mounted on the sealing plate at the outer end, the annular sealing gaskets are arranged on the sealing plates at the outer end and the inner end, the stud penetrates a tail shaft hole, the sealing plate at the outer end clings to the outer end surface of the tail shaft throughthe corresponding annular sealing gasket, the sealing plate at the inner end clings to the inner end surface of the tail shaft through the corresponding annular sealing gasket, the inner end of the stud is fixed to the sealing plate at the inner end, and the sealing plates at two ends are tensioned by the stud, so that the sealing plates at two ends compress the corresponding end surfaces throughthe corresponding annular sealing gaskets to seal. The sealing tool is convenient to dissemble and assemble, can be used repeatedly for many times, is good in sealing property and is harmless to thetail shaft.
