Abstract
Description
Technical Field
[0001] The utility model relates to a ship passage cover, in particular to a cover plate device used for a ship passage. Background Art
[0002] Due to the limited construction space and complicated system of ships, the manhole covers or cover plates used in ship passages can hardly be arranged in the most convenient position for personnel to enter and exit. At present, manhole covers or cover plates are made according to standards. When entering and exiting the cabin, the cover plates need to be pushed open for hook hanging and fixing or flipped 180° for support on the platform or deck.
[0003] Chinese patent CN205186471U discloses "a kind of manhole cover for ship passages". By adding a hinge connecting rod to the cover plate and a hinge seat to the cabin plate, the cover plate and the cabin plate are connected by a hinge structure. In this way, after the manhole cover is disassembled, the manhole cover is suspended on the hinge seat, and a pin control is provided on the hinge connecting rod. When the manhole cover is opened, the cover plate can be fixed with a latch to ensure that the manhole cover will not swing with the swing of the ship in the open state. In this way, the manhole cover is easy to disassemble and assemble, and personnel have more energy to ensure their own safety during the disassembly process. Then, some ship passages are on a horizontal plane, and the layout position is narrow, which does not meet the conditions for the manhole cover to be turned over and laid flat. The flap can only be fixed to the side wall by a hook. Each cover plate is heavier. Not only may the cover plate fall over during the opening process, but the operation process is also cumbersome and there are safety hazards. In addition, the conventional hanging hook structure causes the cover plate to shake and make a loud noise during the connection process. Utility Model Content
