DRILLSHIP THRUSTER PRIMARY LOCKING PIN AND SOCKET

PURPOSE: A thruster fixing equipment of a drilling ship is provided to improve workability by curved surface processing a contact unit inside a main socket and a contact unit in a head unit of a fixing pin. CONSTITUTION: A thruster fixing equipment of a drilling ship comprises a fixing pin (40), a main socket, and an upper socket (60). The fixing pin is equipped in a canister (20) of a thruster which is installed in order to be moved up and down to an upper direction of a trunk (100). The main socket fixes a descended state of the thruster at a lower part of an inner wall surface of the trunk. The upper socket fixes a state ascended and descended of the thruster at an upper part of an inner wall surface of the trunk. The thruster is fixed to an inner wall surface of the trunk by inserting the fixing pin into the main socket and the upper socket. Inserting of the fixing pin, the main socket, and the upper socket is facilitated by curved surface processing a contact unit (61) of the upper socket and the main socket. In the upper socket, a guide groove (63) which guides the fixing pin to enter easily from a lower part is equipped.
