Description
Technical Field
The invention relates to the technical field of ship decks, in particular to a sliding type bulwark door.
Background
When the ocean is sailed, according to the actual use demand of ship type, the bulwark needs the operating mode that can open partially to make things convenient for special goods to get on or off the ship. For example, when a scientific investigation ship sails to a designated place in the ocean, various test suspension arms are extended out from a cabin above a main deck to grab or suspend special equipment, and at the moment, the outer side bulwarks can block the entry and exit of special goods and need to be moved away to make a sufficient space.
For the conventional personnel to get on and off the ship board, the bulwark can be solved only by arranging a hinge type bulwark door with the size of 900 mm; the size of the special cargo or equipment is usually not small and often requires a net space size of more than 3 meters. Due to the limited deck space, the conventional hinge opening mode is not feasible, and the two-side sliding type or hydraulic overturning opening mode is usually adopted. Because the ship is positioned on the side of the ship, the wave-up probability is high when the ship is in a severe sea condition during navigation, the wave-up load calculated by a classification society can even reach 5-7 tons/square meter, and a hydraulic operating mechanism is easy to damage. There are similar scientific investigation ship side door hydraulic operating mechanism damaged and unable working condition.
Due to the special engineering or scientific investigation ship, the bulwark door can still be operated under severe sea conditions. The violent longitudinal and transverse rolling movement of the ship during operation needs to be fully considered, and the bulwark door can not only slide but also cannot be overturned; and can bear the storm load which can be as large as one ton.
Conventional side direction slides, means that slide bulwark door exterior and the whole planking of hull can't be in the coplanar in the open area, bulwark door structure otherwise can not slide to both sides in the fixed bulwark to give way open space. Therefore, the continuity of the hull plates is inevitably broken here, affecting the appearance of the entire ship. Particularly, when scientific research ships are parked for supply in various seaports in the world, the broadside position of the height is most obvious.
For special engineering or scientific research ships, the deformation of the ship body under load is complex due to severe sea conditions. The manual sliding type bulwark door needs to be opened and closed smoothly, bears large storm external load when being closed, prevents loading and tipping during movement, needs to be adapted to hull deformation and convenient disassembly and maintenance under special conditions, and is convenient to maintain.
