Description

Technical Field

[0001] The utility model relates to the technical field of shipbuilding, in particular to a tail shaft sealing hole tooling for moving a ship. Background Art

[0002] When a half-ship is being closed in the dock, when the whole ship needs to be launched, when the half-ship needs to be moved, the stern steel casting has been installed, but the tail shaft propeller has not been installed. At this time, in order to prevent the river water from entering the hull from the tail shaft, the tail shaft hole needs to be blocked. Otherwise, after the river water enters the hull, after the half-ship is positioned and dropped, the cabin needs to be drained, the sand and silt in the cabin need to be cleared, and the cabin needs to be cleaned, which wastes a lot of manpower, material resources and time. The original method is to weld a plate on the flat surface of the tail shaft hole steel casting to block it, and then remove the steel plate after use, and re-grind the steel casting, which will cause certain damage to the surface of the steel casting, and the shipowner's ship inspection has high requirements for the visible surface of the steel casting, so it is necessary to avoid such situations as much as possible.
