Abstract
The invention discloses a hatch cover which comprises a cover plate (1), a coaming (2) and a plurality of locking devices. Each locking device comprises a swing bolt (7), a butterfly nut (8), a pressing plate (9) and a base (10). The base (10) is fixed on the outer wall of the coaming (2). The end, without a thread, of each swing bolt (7) is hinged to one corresponding base (10). The rear portion of each pressing plate (9) is fixed on the cover plate (1), and the front portion of each pressing plate is provided with an opening groove which allows one corresponding swing bolt (7) to pass through. The hatch cover is characterized in that a check ring (5) is fixedly arranged on the bottom face of the cover plate (1), the check ring (5) is welded and fixed with one or more reinforcing ribs to form a frame structure together with the cover plate (1), and a sealing ring (3) is arranged between the check ring (5) and the folded edge of the cover plate (1). The hatch cover is tight in sealing and firm in locking.
Description
Technical field
The present invention relates to install on a kind of ship, relate in particular to a kind of hatch cover.
Background technology
At present, the boats and ships of International Association of Classification Societies (IACS) (IACS) code requirement manufacturing after 2004, the small-sized hatch cover of exposed section in its bow 0.25 captain's scope is the hatch cover that needs to adopt cover plate and latching device reinforcement.Existing steel hatch cover standard can not satisfy its requirement.The cover plate of existing steel hatch cover is the steel plate crimp, the reinforced rib that does not have International Association of Classification Societies's code requirement, its latching device does not all reach the minimum size of International Association of Classification Societies's code requirement at thickness of compressive plate and the diameter of bolt, during cover plate locking, the force part is rubber pad and coaming plate upper end, and coupling mechanism force is not enough.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of and seal closely, lock firm hatch cover.
Solve this technical problem, technical scheme of the present invention is: a kind of hatch cover, comprise cover plate, coaming plate and a plurality of latching device, and cover plate and coaming plate are square tube shape or cylindrical shape, latching device comprises eyelet bolt, fly nut, pressing plate and base.Base is fixed on the outer wall of coaming plate, the not threaded end of eyelet bolt is hinged on the base, the rear portion of pressing plate is fixing on the cover board, its front portion has the open slot that passes for eyelet bolt, its structural feature is to set firmly on the bottom surface of described cover plate educates retaining and pours, this back-up ring constitutes framed structure jointly by weldering above reinforced rib of net and cover plate, is provided with seal ring between the flanging of back-up ring and cover plate.
Be installed with back-up block on the end face of described each base respectively.
The anterior bevel of described pressing plate upwarps.
Compared with prior art, the beneficial effect that has of the present invention is:
1, the present invention is owing on the cover board adopt the reinforced frame structure, thereby improved intensity and the rigidity of cover plate greatly.
2, in latching device because solid welding has back-up block on the eyelet bolt base, thereby when tightening fly nut, bigger predetermincd tension can be arranged, locking firmly, the fly nut ears are long and be circle, can strengthen screwing force, also can add sleeve pipe in case of necessity and tighten.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the local enlarged diagram of the X of Fig. 1.
Fig. 3 is the birds-eye view of figure l.
The specific embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
See also Fig. 1-Fig. 3, a kind of hatch cover comprises cover plate 1, coaming plate 2, seal ring 3, two hinges 4 and a plurality of latching device, and cover plate 1 is square, is made by steel plate punching press flanging, and a side of cover plate 1 is connected with the upper end of a side gate of an imperial palace plate 2 by two hinges 4.Cover plate 1 is locked at the upper port of coaming plate 2 by a plurality of latching devices.Solid welding has a back-up ring 5 on the bottom surface of cover plate 1, and the thickness of back-up ring is identical with the thickness of cover plate, highly strengthens, and is about 50mm, and solid welding has two parallel reinforced ribs 6 in back-up ring 5.Reinforced rib 6 is two-sided welding with the welding of cover plate 1, back-up ring 5, and end sharping and the back-up ring of reinforced rib 6 connect.Make cover plate 1, back-up ring 5 and the reinforced rib 6 common framed structures that constitute one.Seal ring 3 is arranged between the flanging and back-up ring 5 of cover plate 1.Latching device comprises eyelet bolt 7, fly nut 8, pressing plate 9 and base 10.Base 10 solid weldings are on the outer wall of a side gate of an imperial palace plate 2, and solid welding has back-up block II on the base 10.The not threaded end of eyelet bolt 7 is hinged on the base 10, and the rear portion solid welding of pressing plate 9 is on cover plate l, and its front portion has the open slot that passes for eyelet bolt 7, and the anterior bevel of pressing plate 9 upwarps.
Those of ordinary skill in the art will be appreciated that, above embodiment illustrates the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the claim scope of the present invention variation, the modification of the above embodiment.
