Hatch cover apparatus for vessel

Abstract

The present invention relates to a hatch cover for a vessel which comprises a hatch cover which has a rectangular plate shape; a hatch frame which has a rectangular frame shape in order to support the hatch cover; a hatch hinge which is installed on the upper surfaces of the hatch cover and the hatch frame and combines the hatch cover to the hatch frame to be able to rotate; an open protrusion which protrudes in a lateral direction from either the left or the right side surface and rotates to the front by interlocking with the opening operation of the hatch cover; and a side guide bar which has a plate shape extending up and down, whose lower end is coupled to one side of the hatch frame to be able to rotate, where an elongated guide hole is formed along the side surface with the upper part extending further to the back side in order to form a supporting projection, and which is coupled with the open protrusion in order to guide the closing operation of the hatch cover and fix the opening state of the hatch cover. The hatch cover for a vessel can facilitate the opening and closing operation and simply fix the opening state with small power.

Description

technical field [0001] The present invention relates to a hatch cover device, in particular to a ship hatch cover device which can be easily opened and closed and which can be easily fixed in an open state. Background technique [0002] Generally speaking, a hatch is the general designation of hatches and manholes of a ship, especially a through-part that is open on the deck for loading and unloading cargo or for people to come in and out. The size of the hatch should depend on the purpose of use. In order to ensure the strength and safety of the hull, the hatch should be as small as possible, but in order to improve the loading and unloading capacity, the larger the better. [0003] In addition, the channel for loading and unloading cargo into the cabin is called a cargo hatch, and in order to prevent seawater from flowing into the ship, a hatch coaming of sufficient height is set around the hatch and covers its upper part is called a hatch cover. [0004] In addition, in ...

AI Technical Summary

Problems solved by technology

In the case of the prior art, the hatch cover is opened and closed manually by people, and the hatch cover used for the wall is usually set at a place higher than a person, so it needs to be opened and closed with the help of a ladder or a long pole, which is very inconvenient. convenient

[0005] In addition, due to the heavy weight of the hatch cover made of metal, it requires a lot of strength to open it, and the rapid rotation when closing it may easily lead to accidents such as being caught

[0006] In addition, it is prone to bending or damage during repeated opening and closing of the high-weight hatch without additional guiding devices
