HATCH COVER OF SHIP AND HATCH COVER ASSEMBLY USING THE SAME

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of Korean Patent Application No. 10-2013-0011003 filed on 31 January 2013, with the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

BACKGROUND

[0002] The present disclosure relates to a hatch cover and a hatch cover assembly using the same.

[0003] In general, ships transporting masses of goods, such as a cargo ship, a container ship, or the like, have a cargo hold storing goods therein.

[0004] For example, an opening is provided in an upper deck of a ship to allow goods to be loaded into or unloaded from a cargo hold therethrough, and such an opening may be opened and closed by a hatch cover provided in the upper deck.

[0005] A size of a hatch cover may vary according to size or specifications of a ship, and a plurality of partitions are provided therein to reinforce strength.

[0006] Referring to FIG. 1, a hatch cover 10 of a ship 1 may be provided to open and close a cargo hold of the ship 1 transporting transports masses of goods, such as a cargo ship, a container ship, or the like.

[0007] The cargo hold of the ship 1 may have a storage space prepared to store goods, and an opening may be provided in one upper portion of a hull (a body of the ship) 20, for example, in a portion of the upper deck 30, so as to be used as a passage for loading goods to or unloading goods from the cargo hold.

[0008] Also, the hatch cover 10 may be provided in the ship 1 to open and close the opening to protect goods loaded in the cargo hold. The hatch cover 10 is provided in the upper deck 30 of the ship 1 and may be provided to open and close the opening as necessary.

[0009] Also, the size of the hatch cover 10 may vary according to size or specifications of the ship 1. Also, a single hatch cover 10 may be provided in a width direction of the ship 1, or a plurality of hatch covers may be provided and only a portion thereof may be utilized for opening and closing the opening.

[0010] Here, the hatch cover 10 may include a cover body 11 allowing opening and closing of the opening of the ship 1, at least one stacking guide 13 protruding in a center of one transverse directional side of the cover body 11, and a pin stopper 12 serving to prevent the cover body 11 from being released and serving as a rotational center during a position movement of the hatch cover 10 when a shape of the opening is changed as external force is applied to the ship 1. Meanwhile, on the deck 30 of the ship 1, a guide rail 31 guiding the stacking guide 13 may be provided, and a central pin 32 may be fixedly provided to be inserted into the pin stopper 12 at a location corresponding thereto. Also, a pad 33 may be provided between the deck 30 and the cover body 11 to transmit force.

[0011] As illustrated in FIG. 2, the pin stopper 12 provided in the hatch cover 10 may be provided in a position apart from the transverse directional center of the hatch cover 10. This is because both the stacking guide 13 and the pin stopper 12 need to be provided in one transverse directional side of the hatch cover 10, so any one of them is inevitably provided in a position apart from the transverse directional center.

[0012] In this structure, when a shape of the opening is changed due to distortional force applied to the ship 1, the hatch cover 10 is moved in position according to a change in shape of the opening and rotated about the central pin 32. For example, the cover body 11 is rotated to a position indicated by the dotted line in FIG. 2. In this case, a movement amount Dmax of a left side of an upper portion of the cover body 11 is greater than a movement amount Dmin of a right side of a lower portion of the cover body 11. The difference between the movement amounts is caused because a rotational center of the cover body 11 is slanted toward the right side in the transverse direction.

[0013] However, the distortional force applied to the ship 1 is overall equally applied throughout the ship 1, so the opening of the ship 1 is changed to have an overall consistent shape. However, in the case in which the rotational center of the hatch cover 10 is slanted to the right side in the transverse direction, there is a difference between a rotation amount of the hatch cover 10 and deformation of the opening.

SUMMARY

[0014] An aspect of the present disclosure may provide a hatch cover allowing a lower portion to have a movement amount identical to that of an upper portion based on a center in a transverse direction when distortional force is applied to a ship, and a structure of a hatch cover assembly.

[0015] Also, the present disclosure may solve the above problem through a simple change in a structure.

[0016] According to an aspect of the present disclosure, a hatch cover may include: a cover body provided to open and close a cargo hold of a ship; a pin stopper protruded from one side of the cover body in a transverse direction and having a pin hole provided in a vertical direction; and a stacking guide protruded outwardly from the pin stopper in the transverse direction.

[0017] The pin stopper and the stacking guide may be integrally formed.

[0018] The pin stopper and the stacking guide may have a "Ö" shape, and the protruded portion may serve as the stacking guide.

[0019] A center of the pin hole and a center of the stacking guide may be positioned in a center of the cover body in the transverse direction.

[0020] According to another aspect of the present disclosure, a hatch cover assembly may include: the foregoing hatch cover; a guide rail erected on a deck of a ship and further extending in a transverse direction to guide a stacking guide of the hatch cover; and a central pin provided on the deck of the ship and inserted into a pin hole of the hatch cover.

[0021] The guide rail may be provided as a pair of bars having the stacking guide inserted therebetween in the transverse direction.

[0022] A plurality of containers may be disposed in an upper portion of the cover body of the hatch cover in the transverse direction, and a gap between containers disposed closest to the stacking guide may be greater than gaps between other containers .

[0023] A gap between containers disposed closest to the stacking guide may be two or more times greater than gaps between other containers.

DETAILED DESCRIPTION

[0025] Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0026] The disclosure may, however, be exemplified in many different forms and should not be construed as being limited to the specific embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0027] In the drawings, the shapes and dimensions of elements may be exaggerated for clarity, and the same reference numerals will be used throughout to designate the same or like elements.

[0028] FIG. 3 is a plan view illustrating a hatch cover according to an exemplary embodiment of the present disclosure, and FIG. 4 is a reference view illustrating a configuration in which the hatch cover is installed in a ship according to an exemplary embodiment of the present disclosure .

[0029] Referring to FIGS. 3 and 4, a hatch cover 100 according to the exemplary embodiment of the present disclosure may include: a cover body 110, a stacking guide 130 guiding a movement of the cover body 110 to an opening of a ship, and a pin stopper 120 serving to prevent the cover body from being released and serving as a rotation center when external force is applied. Meanwhile, a guide rail 210 guiding the stacking guide 130 and a central pin 220 fixedly provided to be inserted into the pin stopper 120 may be provided on a deck 200 of the ship. Also, a pad 230 may be provided between the deck 200 and the cover body 110 to transmit force.

[0030] The cover body 110 may have a large plate shape and be provided to open and close a cargo hold of the ship. A container 40 may be additionally stacked in an upper portion of the cover body 110, so the cover body 110 may have sufficient rigidity. For example, the cover body 110 may be provided as a steel plate, or the like, having sufficient rigidity.

[0031] The pin stopper 120 may be protruded in one transverse directional side of the cover body 110 and have a pin hole 121 vertically passing through the pin stopper 120. The pin stopper 120 may be positioned in a transverse directional center of the cover body 110. Thus, the pin hole 121 may be positioned in the transverse directional center of the cover body 110.

[0032] The stacking guide 130 may protrude outwardly from the transverse directional side of the pin stopper 120. Also, the stacking guide 130 may be disposed in the transverse directional center of the cover body 110. Also, the stacking guide 130 may be provided as a protrusion protruding from the transverse directional side of the pin stopper 120.

[0033] Meanwhile, the pin stopper 120 and the stacking guide 130 may be integrally formed. The pin stopper 120 and the stacking guide 130 may be provided to have a "ΰ" shape, and the protruded portion in the "ΰ" shape may serve as the stacking guide 130.

[0034] Namely, the pin stopper 120 and the stacking guide 130 may be coupled to the cover body 110 such that the protruded portion in the "ΰ" shape is positioned in an outer side in the transverse direction.

[0035] In addition, in the present disclosure, since the pin stopper 120 only needs to be provided in one side of the cover body 110 in the transverse direction, a stacking guide 135 having a "[HJ" shape may be provided in the other side, opposite to the one side of the cover body 110, in the transverse direction. Of course, in this case, a guide rail 215 provided as having a bar shape on the deck 200 may be provided as having a shape corresponding to the position of the guide rail 215. The present disclosure is not limited thereto, and a stacking guide having a "ΰ" shape may be provided in the other side opposing the one side of the cover body 110 in the transverse direction, and in this case, a guide rail having a shape identical to that provided in the one side of the cover body 110 in the transverse direction may be provided on the deck 200 as described hereinafter.

[0036] Also, a pad 230 may be provided between the deck 200 and the cover body 110 to transmit force. The pad 230 may be formed of an elastic material such as rubber, or the like, to absorb impact applied thereto. One or more pads 230 may be provided on the edges of the cover body 110. In particular, the pad 230 may be provided on a lower surface of the stacking guide 130 or on a lower surface of the pin stopper 120. Also, the pad 230 may be provided on the deck 200 corresponding to the edges of the cover body 110.

[0037] Meanwhile, the hatch cover 100 according to the exemplary embodiment of the present disclosure may be installed on the deck 200 of the ship. Hereinafter, a structure in which the hatch cover 100 is installed on the deck 200 will be referred to as a "hatch cover assembly".

[0038] The hatch cover assembly according to the present exemplary embodiment may include the hatch cover 100, the guide rail 210 provided on the deck 200 of the ship and installed to be erected on the deck 200 to guide the stacking guide 130 of the hatch cover 100, and the central pin 220 inserted into the pin hole 121 of the pin stopper 120 provided in the hatch cover 100 and provided on the deck 200 of the ship.

[0039] Namely, the hatch cover assembly according to the present exemplary embodiment may be disposed on the deck 200 at a position corresponding to the structure of the hatch cover 100 according to the present exemplary embodiment. Meanwhile, the guide rail 210 and the central pin 220 may be provided in an upper portion of a lashing bridge (not shown) provided extendedly in the transverse direction on the deck 200 of the ship. The lashing bridge (not shown) is a fixed structure provided on the deck 200 of the ship to facilitate fixing of the container 40 loaded in an upper portion of the hatch cover 100 of the ship even if the container 40 is stacked as multiple layers.

[0040] The guide rail 210 may be provided as a pair of bars having the stacking guide 130 inserted therebetween. Of course, the guide rail 210 may have the "[H]" shape sufficient space is secured.

[0041] Referring to FIG. 4, a configuration in which the hatch cover 100 according to the exemplary embodiment of the present disclosure is installed on the deck 200 is illustrated.

[0042] The pin stopper 120 provided in the hatch cover 100 may be provided in the center of the cover body 110 in the transverse direction.

[0043] In the structure, when distortional force is applied to the ship 1, a shape of the opening of the ship 1 is changed according to a direction of the force, such that the hatch cover 100 is rotated about the central pin 220 inserted into the pin stopper 120. After the rotation, the cover body 110 is moved to a position indicated by the dotted line in FIG. 4. In this case, a movement amount D1 at a left portion of the upper portion of the cover body 110 is equal to a movement amount D2 at a right portion of the lower portion of the cover body 110. Namely, D1 and D2 are equal. This is caused because the rotation center of the cover body 110 is positioned at the center in the transverse direction.

[0044] Meanwhile, in FIG. 4, a gap G2 between central containers among containers 40 loaded in the upper portion of the hatch cover 100 in the transverse direction may be greater than a gap G1 between central containers among containers 40 loaded in the upper portion of the hatch cover 100 in the transverse direction illustrated in FIG. 2. In detail, the gap G2 may be two or more times greater than G1. Namely, a plurality of containers 40 may be disposed in the upper portion of the cover body 110 of the hatch cover 100 in the transverse direction, and here, the gap between the containers disposed closest to the stacking guide 130 may be greater than those between other containers. In addition, the gap between the containers disposed closest to the stacking guide 130 may be two or more times greater than those between the other containers. In the case of using the hatch cover assembly according to the exemplary embodiment of the present disclosure, the containers 40 may be loaded in the upper portion of the hatch cover 100, and the above configuration is used in order to easily fix the loaded containers 40. Hereinafter, details thereof will be described with reference to FIG. 5.

[0045] FIG. 5 is a reference view illustrating a configuration in which containers are loaded in an upper portion of the hatch cover and fixed according to an exemplary embodiment of the present disclosure.

[0046] Referring to FIG. 5, the containers 40 may be installed in the upper portion of the hatch cover 100. In addition, lashing eyes 240 are fixedly provided as means of fixing the loaded containers 40 on the deck 200 of the ship. In detail, the lashing eyes 240 may be provided in an upper portion of a lashing bridge (not shown) provided extendedly in the transverse direction on the deck 200 of the ship. The containers 40 may be connected to lashing bars 250 connected to the lashing eyes 240 to be firmly fixed to predetermined positions.

[0047] Meanwhile, in the case of the hatch cover assembly according to the exemplary embodiment of the present disclosure, the guide rail 210 may be provided to be even longer in the transverse direction. Namely, by having the stacking guide provided in the hatch cover 100 to have the "ΰ" shape and the guide rail 210 guiding the stacking guide 130 to have the "(Η]" shape, the guide rail 210 may be provided to be extended further in the transverse direction.

[0048] Here, in general, a pair of lashing eyes 240 is provided at locations corresponding to both end portions of each container 40 in the transverse direction. Thus, in the exemplary embodiment of the present disclosure, the gap G2 between the central containers among the containers 40 loaded in the upper portion of the hatch cover 100 is adjusted to be greater to allow the lashing bars 250 connected to the lashing eyes 240 to exert sufficient fixing force.

[0049] As set forth above, according to exemplary embodiments of the present disclosure, although distortional force is applied to a ship, upper and lower portions of a hatch cover may have the same movement amount based on a center in a transverse direction.

[0050] In addition, when the exemplary embodiments of the present disclosure are used, even if distortional force is applied to a ship, a rotation amount of the hatch cover and a deformation amount of an opening may be approximately equal.

[0051] Also, when the exemplary embodiments of the present disclosure are used, movement amounts of respective portions of the hatch cover may be balanced when a ship is distorted by simply altering a structure of a stacking guide.

[0052] While exemplary embodiments have been shown and described above, it will be apparent to those skilled in the art that modifications and variations could be made without departing from the spirit and scope of the present disclosure as defined by the appended claims.
