Technical Field

The invention relates to the technical field of ship construction, in particular to a bidirectional limiting device and a bidirectional limiting method for a ship cabin door.

Background

The opening and closing of the hatch door is very frequent during the use of the ship. Generally, the mass of a ship cabin door is large, and a worker often collides with equipment behind the door to cause damage due to improper control in the process of opening the cabin door. In addition, the rolling hold is susceptible to adverse effects when the crew performs some handling action. Therefore, a door opening and closing limit measure is required.

Conventionally, an iron chain is arranged on the cabin door to prevent the cabin door from being closed accidentally, but the disadvantage of accidental collision of the cabin door is not eliminated because the iron chain only can limit movement in one direction and is not a rigid structure. It is also possible to weld the deck surface with a stop-blocking hatch, but the above-mentioned drawbacks also occur and can damage the flatness of the deck, reducing the safety of the ship.
