Problems solved by technology
The traditional method is to prepare a circular outer sealing plate to seal the stern shaft hole by welding. figure 1 As shown, this method is simple and practical, but its disadvantages are also very obvious. The end of the stern shaft is a casting, and welding will greatly damage the base metal. Since the end has high requirements for flatness, it must be polished and smooth after removal.

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.
Description
technical field [0001] The present disclosure relates to the technical field of shipbuilding, in particular to a semi-ship floating stern shaft sealing tool and a sealing method. Background technique [0002] With the rapid development of shipbuilding technology, half-ship floating is becoming more and more common in order to improve the efficiency of dock utilization. At this time, many ship systems are not perfect, so it is very important to ensure the safety of ships. How to ensure that the stern shaft is sealed in place is the most important thing. The stern shaft is directly connected to the engine room, and there are many equipments inside. Once an accident occurs, the consequences will be disastrous. The traditional method is to prepare a circular outer sealing plate to seal the stern shaft hole by welding. figure 1 As shown, this method is simple and practical, but its disadvantages are also very obvious. The end of the stern shaft is a casting, and welding will gre...
