RAIL DEVICE FOR RAISING A CONNECTION POINT OF A MAIN HULL WITH AN AUXILIARY BUOYANCY DEVICE IN A NON-OVERTURNED SHIP CAPABLE OF PREVENTING THE OVERTURN OF A SHIP

摘要

PURPOSE: A rail device for raising a connection point of a main hull with an auxiliary buoyancy device in a non-overturned ship is provided to prevent the overturn of a ship because a ship is maintained in an erected state by rotating a main hull body.;CONSTITUTION: A rail device(41) for raising a connection point of a main hull with an auxiliary buoyancy device in a non-overturned ship comprises a main rail(51), a moving rail(52), and bidirectional latches(43). The rail device is installed inside a stem and a stern to which a connection bar is connected at first and second buoyancy devices. The length of the rail device is same as the length of the first and second buoyancy devices from the bottom to the top of a ship. The width and thickness of the rail device is adjusted according to the length of the rail device and the conditions of a hull. The main rail comprises slide grooves(31) and rotary shafts(42). The moving rail is vertically moved in the slide grooves by the self weight thereof. The bidirectional latches are coupled to the rotary shafts to move the moving rail only in an upward direction.;COPYRIGHT KIPO 2013
