[0024] Next, a preferred embodiment is given and the accompanying drawings are used to more clearly and completely illustrate the present invention.

[0025] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, a detachable hatch coaming structure, which includes a hatch coaming plate 20 and a bracket 30 provided on the ship deck 10; the bracket 30 is fixedly connected to the outer side wall of the hatch coaming plate 20.

[0026] The hatch coaming plate 20 is composed of an upper coaming plate 21 and a lower coaming plate 22. In this embodiment, the height of the lower coaming plate 22 is 300 - 400 mm. The height of the lower coaming plate is slightly lower than the height of the packing block.

[0027] The bracket 30 includes an upper bracket 31 and a lower bracket 32.

[0028] The lower end of the lower coaming plate 22 and the lower end of the lower bracket 32 are both fixedly connected to the deck, the upper end of the lower coaming plate 22 is fixedly provided with a first horizontal flange plate 41, and the upper end of the lower bracket 32 is fixedly connected to the bottom of the first horizontal flange plate 41.

[0029] The lower end of the upper coaming plate 21 is fixedly provided with a second horizontal flange plate 42; the lower end of the upper bracket 31 is fixedly connected to the top of the second horizontal flange plate 42.

[0030] The first horizontal flange plate 41 and the second horizontal flange plate 42 are connected by bolts.

[0031] A vertical flange plate 43 is also provided between the upper coaming plate 21 and the lower coaming plate 22. The vertical flange plate 43 is fixedly connected to the inner side wall of the upper coaming plate 21 and the inner side wall of the lower coaming plate 22 by bolts respectively.

[0032] The bolts connecting the first horizontal flange plate 41 and the second horizontal flange plate 42 are distributed on both sides of the bracket 30.

[0033] The bolts connecting the vertical flange plate 43 and the upper coaming plate 21 are distributed on both sides of the bracket 30.

[0034] The bolts connecting the vertical flange plate 43 and the lower coaming plate 22 are distributed on both sides of the bracket 30.

[0035] The hatch coaming may be provided with drain holes or may not be provided with drain holes.

[0036] In this embodiment, the hatch coaming 20 is provided with a plurality of drain holes 63.

[0037] The drain holes 63 straddle the upper coaming and the lower coaming; the first horizontal flange plate 41 and the second horizontal flange plate 42 are not distributed at the drain holes; the vertical flange plate 43 is provided between adjacent drain holes.

[0038] The left end and the right end of the first horizontal flange plate 41 between adjacent drain holes 63 are respectively located on both sides of the bracket 30; the left end and the right end of the second horizontal flange plate 42 between adjacent drain holes 63 are respectively located on both sides of the bracket 30.

[0039] In other embodiments, the hatch coaming is not provided with drain holes, and the first horizontal flange plate is continuously distributed along the hatch coaming; the second horizontal flange plate is continuously distributed along the hatch coaming.

[0040] The hatch coaming 20 includes a longitudinal coaming 51 distributed along the longitudinal direction of the ship and a transverse coaming 52 distributed along the transverse direction of the ship.

[0041] There are two longitudinal coamings and two transverse coamings respectively, and the two longitudinal coamings and the two transverse coamings enclose a rectangular loading area.

[0042] At the connection of the longitudinal coaming and the transverse coaming, the first horizontal flange plate, the second horizontal flange plate and the vertical flange plate are also provided.

[0043] The longitudinal coaming 51 and the transverse coaming 52 are connected at a right angle, and a vertical flange plate is provided at the connection of the longitudinal coaming 51 and the transverse coaming 52; the vertical flange plate is an L-shaped vertical flange plate 44, and the L-shaped vertical flange plate 44 is connected to both the longitudinal coaming 51 and the transverse coaming 52 at the same time.

[0044] The longitudinal coaming 51 extends to the outside of the connection of the longitudinal coaming and the transverse coaming. A bracket 60 provided on the outer wall of the longitudinal coaming and the transverse coaming 52 are in the same plane.

[0045] The first horizontal flange plate 45 at the connection of the longitudinal coaming 51 and the transverse coaming 52 is continuously distributed between the longitudinal coaming 51 and the transverse coaming 52.

[0046] The second horizontal flange plate 46 at the connection of the longitudinal coaming 51 and the transverse coaming 52 is continuously distributed between the longitudinal coaming 51 and the transverse coaming 52.

[0047] The free edge of the end of the longitudinal coaming 51 is provided with a panel 61. The free edge of the end of the longitudinal coaming is transitioned with an arc from top to bottom to reduce the stress concentration at the end.

[0048] In the normal use state, that is, when loading goods with smaller sizes in the loading area surrounded by the hatch coaming, the first horizontal flange plate and the second flange plate are fixedly connected by bolts, and the vertical flange plate is fixedly connected to the upper coaming and the lower coaming by bolts. In this way, the hatch coaming can achieve the normal function of loading goods.

[0049] When it is necessary to load goods with larger sizes, the upper coaming can be removed by disassembling the bolts. The height of the lower coaming is slightly lower than the height of the dunnage. By laying dunnage on the deck, the goods with larger sizes can be placed in the loading area.

[0050] In the present invention, the lower coaming is welded to the hull deck, and a double-flange bolt connection method with a horizontal plane and a vertical plane is adopted between the upper coaming and the lower coaming.

[0051] The horizontal flange bolt connection structure can withstand the vertical tension caused by the bending moment resulting from the lateral load of the hatch coaming, avoiding the vertical flange bolt connection structure from bearing excessive shear force.

[0052] The vertical flange bolt connection structure can withstand the horizontal tension caused by the lateral load of the hatch coaming, avoiding the horizontal flange bolt connection structure from bearing excessive shear force.

[0053] The horizontal flange bolt connection structure and the vertical flange bolt connection structure cooperate with each other to obtain a better connection effect, which not only ensures the structural strength of the hatch coaming itself, but also enables the upper and lower parts of the hatch coaming to meet the detachable requirement of the upper coaming.

[0054] The present invention makes the hatch coaming structure in a detachable form, which can not only meet the requirements of the structural strength of the hatch coaming itself, but also load goods with larger sizes. It can not only effectively increase the deck area of the loadable area, but also connect the discrete areas into a large usable deck area.

[0055] Although the specific implementation manners of the present invention have been described above, those skilled in the art should understand that this is only an example. The protection scope of the present invention is defined by the appended claims. Without departing from the principles and essence of the present invention, those skilled in the art can make various changes or modifications to these implementation manners, but these changes and modifications all fall within the protection scope of the present invention.
