The utility model discloses an extension
deck for a
deck transport ship, which belongs to the technical field of transport ship decks and comprises a storage shell, an extension plate is slidably connected in the storage shell, a support is fixedly connected to the upper surface of the storage shell, a hydraulic rod is fixedly connected to the inner wall of the support, and a key controller is fixedly connected to the upper surface of the support. The inner wall of the storage shell is fixedly connected with a
servo motor, and the output end of the
servo motor is fixedly connected with a
threaded rod. According to the extension
deck for the deck transport ship, through mutual cooperation of a storage shell, an extension plate, a support, a hydraulic rod, a key controller, a connecting plate, a limiting block, a
servo motor, a
threaded rod, a limiting groove, a guide rod, a
damper, a return spring and a buffer plate, the key controller can be operated to control the servo motor to be powered on to drive the
threaded rod to rotate; and therefore, the extension plate in threaded connection with the threaded rod can slide in the storage shell in a reciprocating manner, and the extension plate can stretch out or be stored relative to the storage shell.
