Abstract

The invention discloses a ship side door structure. The structure comprises a side door body, sealing rubber strips, connecting rod oil cylinders and operating oil cylinders. A door frame is formed between an upper platform of a ship and a deck, the sealing rubber strip is arranged on the edge of the door frame in the circumferential direction of the door frame, one side of the side door body is connected with a deck shaft, and when the side door body is closed, the included angle between the side door body and the horizontal plane is an acute angle. The side door body comprises a first gangplank, a second gangplank and a folding oil cylinder. One side of the first gangplank is connected with the deck through a shaft, the side, opposite to the deck, of the first gangplank is connected withthe second gangplank through a shaft, and a base of the folding oil cylinder is installed on the first gangplank in a hinged mode. According to the ship side door structure, the acute angle is formedbetween the side door body and the horizontal plane when the side door body is closed. When the side door body enters water, water can supply inward pushing force to the side door body, it is guaranteed that the side door has enough pressing force when closed, and the sealing effect is improved.

Description

technical field

[0001] The invention belongs to the technical field of ship building, and in particular relates to a ship side door structure. Background technique

[0002] The ship's side door is used for the entry and exit of vehicles, and is the key to the entire channel system. When the side door is opened, it can facilitate the entry and exit of vehicles. When the side door is closed, it effectively separates the outside of the hull and the vehicle garage, and plays the role of a watertight bulkhead. The traditional side door structure adopts an integrated structure. When the side door is closed, it adopts front sealing and pressing, that is, when the door panel is lifted and closed, the sealing strip is pressed when the door panel is lifted and closed. The sealing pressure is closely related to the pressing force, and the weight of the side door Large, it is difficult to ensure sufficient pressing force, and the sealing performance of the side door cannot be guarantee...
