Description

Container loading aids and container carriers

[0001] The present invention relates to a container loading assist device and a container carrier.

[0002] Container carriers are increasingly expanding their container loading capacity, and alongside this increase, ensuring the stability of loaded containers during transit is being highlighted as a critical factor.

[0003] These container ships load containers into cargo holds provided in the fore-and-aft direction within the hull using a structure called a cell guide, and then load the containers in multiple layers onto the hatch covers after installing the hatch coamings at the entrances of the cargo holds on the upper deck of the hull. To prevent the containers loaded on the hatch covers from tipping over, they are secured using various fittings on lashing bridges located above the space between the cargo holds.

[0004] Hatch covers not only support the load of containers loaded on the upper deck and block the inflow of foreign substances (such as seawater or rain) into the cargo hold, but also contribute to reinforcing the longitudinal strength of the container ship.

[0005] However, hatch covers not only present the inconvenience of being difficult to produce, transport, and load due to their heavy weight, but also require an additional structure to be provided at the entrance of the cargo hold, which occupies a significant amount of space between adjacent cargo holds, thereby preventing the loading of containers in that area.

[0006] Recently, research has been conducted on small container ships with an open-top concept that lacks hatch covers to solve the problems of production, transportation, and installation of hatch covers while shipping more containers.

[0007] When applying the open-top concept to small container ships, there are problems such as damage to the lower containers due to the load of the loaded containers and issues with the ship's trim and stability, which necessitate limiting the number of containers (tiers) continuously loaded from the bottom of the cargo hold to the upper deck to a certain number (e.g., 12 tiers), and there are problems such as having to raise the side plates excessively high and reinforce the hull strength compared to container ships of the same loading size to prevent green water from entering the ship's deck in rough seas during ship operation.

[0008] In large container ships, to prevent containers loaded on top of hatch covers from tipping over, it is necessary to secure and unsecure them to the lashing bridge using various fittings during unloading. Since this process is mostly performed manually, it requires excessive working time and safety management, resulting in operational costs for the container ship. Furthermore, when excessive hull movement occurs due to adverse weather conditions during operation, problems arise where the lashing system collapses due to incomplete elements—such as hatch covers shifting under load, fastening devices on the deck or hatch covers breaking, lashing bridge fittings snapping, or relative displacement between the hatch cover and the hull—ultimately leading to the damage or loss of loaded containers into the sea.

[0009] The present invention was created to solve the problems of the prior art as described above, and the objective of the present invention is to provide a container loading assist device and a container carrier that increase the loading capacity by increasing the number (units) of containers continuously loaded from the bottom of the cargo hold to the upper deck of a large container carrier.

[0035] The objects, specific advantages, and novel features of the present invention will become more apparent from the following detailed description and preferred embodiments in conjunction with the accompanying drawings. It should be noted that in assigning reference numerals to the components of each drawing in this specification, identical components are assigned the same number whenever possible, even if they are shown in different drawings. Furthermore, in describing the present invention, detailed descriptions of related prior art are omitted if it is determined that such detailed descriptions would unnecessarily obscure the essence of the invention.

[0036] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0037] FIG. 1 is a longitudinal section view of a container carrier according to a first embodiment of the present invention, FIG. 2 is a partial cross-sectional view of a container carrier according to a first embodiment of the present invention, and FIG. 3 to 8 are drawings for explaining a container carrier according to a first embodiment of the present invention and a container loading assist device provided therein. In addition, FIG. 9 (a) to (c) are drawings for explaining a method of unloading a container using a container loading assist device on a container carrier according to a first embodiment of the present invention.

[0038] As illustrated in (a) to (c) of FIGS. 1 to 8 and FIGS. 9, a container carrier (1) according to the first embodiment of the present invention can transport containers (C) in multiple layers inside and outside the hull (10) from a starting point to a destination, and as a new concept container carrier without a hatch cover, it may be equipped with a container loading assist device (100) for loading and supporting containers (C).

[0039] In this embodiment, the container carrier (1) may be a large container carrier capable of loading a large number of containers (C) in 13 layers or more, including the amount loaded from the bottom of the cargo hold (17) to the upper deck (11), but is not limited thereto. Additionally, the containers (C) may include 20ft containers (hereinafter referred to as "small containers"), 40ft containers (hereinafter referred to as "large containers"), or containers of 45ft or more (hereinafter referred to as "maximum containers") that are mainly loaded on the container carrier (1). However, according to ISO standards, not only are containers of various sizes (C) used for ships in addition to the 20ft or 40ft mentioned above, but there are also containers (C) with various specifications; therefore, it should be noted that the small containers (C) or large containers (C) mentioned below are not used in the sense of being limited to 20ft or 40ft.

[0040] The hull (10) forms the exterior of the container ship (1). The hull (10) is surrounded by an upper deck (11), side plates (12), and bottom plates (13).

[0041] This hull (10) can be formed with a double hull structure in which the side plate (12) is composed of a side outer plate (12a) and a side inner plate (12b), and a double bottom structure in which the bottom plate (13) is composed of a bottom outer plate (13a) and a bottom inner plate (13b).

[0042] Containers (C) can be loaded inside the hull (10). To this end, a plurality of cargo holds (17) are provided inside the hull (10), which are partitioned in the front-rear direction by transverse bulkheads (16). In the cargo holds (17), lower cell guides (31) are installed at regular intervals on the sides of the transverse bulkheads (16) to guide the loading of containers (C) inside the cargo holds (17).

[0043] In this embodiment, the cargo hold (17) has an open entrance structure, and instead of a conventional hatch cover being installed at the entrance, the container loading assist device (100), which will be described later, can be configured to be mounted at the entrance of the cargo hold (17) or at any location inside the cargo hold (17). That is, the entrance of the cargo hold (17) can be made of a simple structure so that the container loading assist device (100) can be mounted. When the container loading assist device (100) is mounted inside the cargo hold (17), a groove (not shown) can be formed in the upper deck forming the entrance of the cargo hold (17) so that the container loading assist device (100) can pass through the entrance of the cargo hold (17).

[0044] In addition, when the container loading assist device (100) of the present embodiment is applied to a container carrier (1) having an existing lashing bridge or a container carrier (1) having a hatch coaming at the entrance of a cargo hold (17), it can be mounted on the hatch coaming on the upper deck (11) of the entrance of the cargo hold (17).

[0045] An engine room (R) may be provided in a location adjacent to the stern (15) inside the hull (10). A propulsion engine (not shown) is housed in the engine room (R), and the propulsion engine is mechanically or electrically connected to a propeller to rotate the propeller by consuming liquefied gas as fuel.

[0046] A cabin (A) is provided on the upper deck (11) of the hull (10). The cabin (A) is a living space for the crew and can be divided into multiple layers in the vertical direction, and a control room for controlling navigation can be provided on the uppermost layer.

[0047] An engine casing (I) is provided at the rear of the cabin (A) on the upper deck (11) of the hull (10). The engine casing (I) has a chimney for discharging exhaust from the propulsion engine to the outside and may also form a space for an emergency generator or fire extinguishing facility.

[0048] Containers (C) can be loaded on the upper deck (11) of the hull (10), excluding the cabin (A) and the engine casing (I). To load the containers (C), a top bridge (20) is provided on the upper deck (11) at a certain distance apart in the front-rear direction.

[0049] The top bridge (20) can be installed extending to the left and right edges of the upper deck (11) between the cargo holds (17), and can be arranged at regular intervals from the bow (14) to the stern (15).

[0050] Upper cell guides (32) may be installed at regular intervals on both sides of the top bridge (20). That is, the top bridge (20) of this embodiment is not a lashing bridge to which a conventional lashing system is applied, but a cell guide system to which upper cell guides (32) are applied.

[0051] Each upper cell guide (32) can be integrally formed by connecting each lower cell guide (31), which extends from the top of the top bridge (20) to the upper deck (11) and is installed inside the cargo hold (17). Additionally, the upper cell guide (32) is integrally connected to the lower cell guide (31) to form a continuous guide path for the container (C). When the container loading assist device (100) is lowered by using a crane (CR) to bring it into the upper cell guide (32), the container loading assist device (100) can be lowered while being guided by the upper cell guide (32) and brought into the guide path.

[0052] The upper cell guide (32) guides the lifting and lowering of a small container (C) or a large container (C) being transported by a crane (CR), and the upper cell guide (32) provided on the top bridge (20) and the lower cell guide (31) installed on the transverse bulkhead (16) are connected to each other, so that continuous loading or unloading operations can be performed without additional work such as installing a hatch cover or lashing work when unloading the container (C). The upper cell guide (32) can support the lateral load of the small container (C) or the large container (C) generated by the movement of the hull (10).

[0053] The top bridge (20) of the present embodiment is configured such that upper cell guides (32) are installed on both sides, thereby allowing the upper cell guides (32) to support and fix the container (C), thus eliminating the need for a conventional lashing system (fastening device such as a lashing rod or lashing bar), and can be configured to prevent the container (C) from tipping over at the front and rear of the container (C) which is generally loaded at 1 to 4 tier levels, and to secure access and work space for maintenance and monitoring of the control unit, etc., provided in the reefer container (C), and can solve the problem of the loaded container (C) being damaged or lost by directly supporting the container (C) on the upper deck (11) during the operation of the container carrier (1).

[0054] The top bridge (20) can be composed of a combination of a plurality of vertical members (21) and a plurality of horizontal members (22).

[0055] Among the plurality of vertical members (21), the outer vertical members (21a), which are arranged in pairs on the upper deck (11) on the left and right sides of the hull (10), can be arranged at intervals corresponding to the width of a small container (C) or a large container (C).

[0056] Among the multiple vertical members (21), the multiple intermediate vertical members (21b) arranged between the outer vertical members (21a) can be arranged at intervals corresponding to twice the width of the small container (C) or large container (C).

[0057] At this time, the upper cell guide (32) can be positioned between each of the outer vertical member (21a), the plurality of intermediate vertical members (21b), and the plurality of intermediate vertical members (21b).

[0058] In addition, the top bridge (20, 20a, 20b) may further enhance the safety of the loaded container (C) by additionally placing at least one of the lashing eye, lashing ring, lashing plate, plug, and cone, which are fasteners of the lashing system, so that an existing lashing system can be additionally applied to the top.

[0059] Although the container carrier (1) according to the first embodiment of the present invention described above is described as having a top bridge (20) with a cell guide system applied thereto, it is not limited thereto, and it is understood that a lashing bridge with a lashing system applied thereto may be installed in some rows or in some sections on the left and right sides of a single row, similar or identical to the existing one. That is, it is noted that the container carrier (1) according to the first embodiment of the present invention may have a hybrid type bridge in which the top bridge (20) with the cell guide system of the present invention and the lashing bridge with the existing lashing system applied thereto are mixed.

[0060]

[0061] A container carrier (1) according to the first embodiment of the present invention may be equipped with a container loading assist device (100).

[0062] The container loading assist device (100) is provided on a container carrier (1) without a hatch cover and may be configured to be applied to at least one cargo hold (17) to load and support a small container (C) or a large container (C) on top, and may include an upper frame (111), a lower frame (112), a support member (113), a protruding member (120), a reinforcing frame (130), a first fitting member (141), and a second fitting member (142). The container loading assist device (100) may form a main body (110) in which the upper frame (111), the lower frame (112), and the support member (113) are combined to form an overall shape in the form of a rectangular box.

[0063] The upper frame (111) can be configured in a rectangular shape having a width corresponding to the width of a small container (C) or a large container (C) and a length corresponding to the length of a large container (C).

[0064] The upper frame (111) may be composed of a pair of first long frame (111a) that are arranged with a width corresponding to the width of a small container (C) or a large container (C) and have a length corresponding to the length of a large container (C), and a pair of first short frame (111b) that connect the ends of each of the pair of first long frame (111a) and have a width corresponding to the width of a small container (C) or a large container (C).

[0065] The lower frame (112) can be configured in a rectangular shape having a width corresponding to the width of the small container (C) or the large container (C) and a length corresponding to the length of the large container (C).

[0066] The lower frame (112) may be composed of a pair of second long frame (112a) that are arranged with a width corresponding to the width of the small container (C) or large container (C) and have a length corresponding to the length of the large container (C), and a pair of second short frame (112b) that connect the ends of each of the pair of second long frame (112a) and have a width corresponding to the width of the small container (C) or large container (C).

[0067] In the above, each of the pair of second long-axis frames (112a) may be configured such that both ends are connected to the lower end of the support (113) to be described later, and as they go inward, they have a downward slope and are then bent so that they are level with each of the pair of first long-axis frames (111a) in the middle portion.

[0068] Support members (113) may be provided in multiple numbers in the height direction on the upper frame (111) and the lower frame (112), and may be configured to connect each of the square corners of the upper frame (111) and each of the square corners of the lower frame (112).

[0069]

[0070] The protruding member (120) may be configured to protrude outward from the upper and lower frames (111, 112) or the support (113) so as to be mounted at any position of the cargo hold (17). The protruding member (120) may be configured to protrude outward in the longitudinal direction from the bottom of each support (113) so as to be mounted at the entrance of the cargo hold (17) or at any position inside the cargo hold (17).

[0071] When the protruding member (120) is mounted on the upper deck (11) of the entrance of the cargo hold (17), the load of the small container (C) or large container (C) transmitted through the support (113) can be transmitted to the upper deck (11).

[0072] When a protruding member (120) is mounted at any position inside the cargo hold (17) using a position adjustment member (not shown), the upper deck (11) at the entrance of the cargo hold (17) may have a groove formed in the portion where the protruding member (120) is mounted, through which the protruding member (120) passes. Accordingly, after passing through the groove formed in the upper deck (11), the protruding member (120) is mounted on a position adjustment member installed at any position on the transverse bulkhead (16) inside the cargo hold (17), and can transfer the load of a small container (C) or a large container (C) transmitted through the support (113) to the transverse bulkhead (16).

[0073] When the container loading assist device (100) of the present invention is applied to an existing container carrier in which a lashing bridge is installed or to an existing container carrier in which a hatch coaming is present at the entrance of a cargo hold (17), a protruding member (120) may be mounted on the upper hatch coaming of the upper deck (11) at the entrance of the cargo hold (17).

[0074]

[0075] The reinforcing frame (130) connects the middle portion along the length direction of the upper frame (111) and the middle portion along the length direction of the lower frame (112), and can support the load of a small container (C) or a large container (C) loaded on the upper surface of the container loading aid (100).

[0076] The reinforcing frame (130) may be composed of a first horizontal reinforcing member (not shown) connecting the middle portions of each of a pair of first long-axis frames (111a), a second horizontal reinforcing member (not shown) connecting the middle portions of each of a pair of second long-axis frames (112a), a first vertical reinforcing member (not shown) connecting one end of the first horizontal reinforcing member and one end of the second horizontal reinforcing member, and a second vertical reinforcing member (not shown) connecting the other end of the first horizontal reinforcing member and the other end of the second horizontal reinforcing member.

[0077]

[0078] The first fitting member (141) is provided at the top of each of the square corners of the upper frame (111) and can be used for fixing when loading a large container (C) or a small container (C), or for lifting when transporting with a crane (CR).

[0079] The second fitting member (142) is provided as a pair on the upper part of the middle section of the upper frame (111) and can be used for fixing when loading a small container (C), or can also be used for lifting together with the first fitting member (141) when transporting with a crane (CR).

[0080] In the above, the first fitting member (141) can be formed at the same height at each of the square corners of the upper frame (111), and the second fitting member (142) is provided at the top of the middle part of each of the pair of first long-axis frames (111a), and can be formed 5mm to 15mm higher than the height of the first fitting member (141) so that when two small containers (C) arranged in the longitudinal direction are loaded, they tilt inward due to buckling caused by the load, but the two small containers (C) facing each other do not come into contact.

[0081] The container loading assist device (100) of the present invention is equipped with a first fitting member (141) and a second fitting member (142), so that, unlike conventional similar technology, small containers (C) and large containers (C) can be mixed and safely fixed on the upper surface.

[0082]

[0083] The container loading assist device (100) may further include a first plate (151), a second plate (152), a watertight member (153), and a reinforcing member (160).

[0084] The first plate (151) can be installed on a one-sided frame formed by one of a pair of first long-axis frames (111a), one of a pair of second long-axis frames (112a), and a support (113) connecting both ends thereof.

[0085] The second plate (152) can be installed on the other side frame formed by the other of the pair of first long-axis frames (111a), the other of the pair of second long-axis frames (112a), and a support (113) connecting both ends thereof.

[0086] The watertight member (153) can be configured to block water (seawater or rainwater) from entering the cargo hold (17) when the container loading aid (100) is mounted on the upper deck (11) of the cargo hold (17) entrance and a container (C) is loaded on top thereof, and may include a first watertight plate (153a), a second watertight plate (153b), and a third watertight plate (153c).

[0087] The first watertight plate (153a) can be installed on an upper frame formed by a pair of first long-axis frames (111a) and a pair of first short-axis frames (111b) that form the upper frame (111), and can block water from flowing into the cargo hold (17) through the upper part of the container loading assist device (100).

[0088] The second watertight plate (153b) can be installed on the front and rear frame formed by the first short frame (111b) of the upper frame (111), the support (113), and the protruding member (120), and can block water from flowing into the cargo hold (17) through the front and rear portions of the container loading assist device (100). The lower portion of the second watertight plate (153b) protrudes outward in correspondence with the shape of the protruding member (120), and is thereby positioned on the upper deck (11) of the cargo hold (17) entrance.

[0089] The third watertight plate (153c) can be installed at a certain height along the edge of each of the pair of first long-axis frames (111a) forming the upper frame (111), and can block water from flowing into the cargo hold (17) by directing water accumulated on the first watertight plate (153a) to the second watertight plate (153b) forming the side of the container loading aid (100).

[0090] A third watertight plate (153c) installed along the edge of each of a pair of first long-axis frames (111a) may have a gap greater than the width of the small container (C) or large container (C) so as not to be damaged when the small container (C) or large container (C) is fixed to the first and second fitting members (141, 142), or the height of the third watertight plate (153c) may be formed lower than that of the first fitting member (141) and the second fitting member (142).

[0091] As described above, the container loading assist device (100) having a watertight member (153) is mounted on the upper deck (11) at the entrance of the cargo hold (17), and when a container (C) is loaded on the upper deck, if water flows down the side wall of the container (C), water accumulates on the first watertight plate (153a), and the accumulated water is not allowed to overflow to the side of the container loading assist device (100) by the third watertight plate (153c) and flow into the cargo hold (17), but can be drained to the upper deck (11) through the second watertight plate (153b).

[0092]

[0093] The reinforcing member (160) may be installed on at least one of the outer and inner sides of each of the first plate (151) and the second plate (152).

[0094] The reinforcing member (160) may be composed of an intermediate reinforcing member (161) connected to each of a pair of first long-axis frames (111a) and each of a second long-axis frame (112a) so as to face each of a first long-axis frame (111a) and each of a second long-axis frame (112a) with the first plate (151) and the second plate (152) in between when installed on the outer surface of each of the first plate (151) and the second plate (152), and first and second reinforcing members (162, 163) arranged between the supports (113) on both sides based on the intermediate reinforcing member (161) and connected to each of the pair of first long-axis frames (111a) at the bending portion of each of the pair of second long-axis frames (112a).

[0095] In this embodiment, although a pair of second long-axis frames (112a) are described as having a folded shape, it is understood that they can be formed in a flat shape. That is, the container loading assist device (100) of this embodiment can be manufactured in the shape of a rectangular box.

[0096] The container loading assist device (100) of the present invention may have all or part of a reinforcing frame (130), a first plate (151) and a second plate (152), and a reinforcing member (160), thereby securing rigidity capable of supporting the load of a container (C) loaded on top independently, unlike conventional similar technology.

[0097]

[0098] The container loading assist device (100) may further include a stacking member (170) that vertically connects and / or supports the main body (110).

[0099] The stacking member (170) may have a structure that can be switched from a first state of being stacked on a transport vehicle or on land to a second state of being stacked on a container transport ship (1).

[0100] The stacking member (170) may consist of a stacking bridge (171) installed on the outer side in the width direction on each side of the support member (113), and a third fitting member (172) provided at the bottom of each stacking bridge (171) and connected to a first fitting member (141) provided on the main body (110) that is stacked on top when stacking the main body (110) in multiple layers.

[0101] The stacking bridge (171) can be configured so that when the main body (110) is stacked in multiple layers using the first fitting member (141) and the third fitting member (172), a pair of second fitting members (142) provided on the main body (110) stacked at the bottom do not come into contact with the lower frame (112) of the main body (110) stacked at the top.

[0102] That is, the stacking bridge (171) can be formed with a length such that when the container stacking aid (100) is stacked vertically, the bottom part of the container stacking aid (100) stacked on top and the top part of the container stacking aid (100) stacked on the bottom do not come into contact, because there is a possibility of damage due to contact friction when shaking occurs due to external environmental factors while the upper and lower container stacking aids (100) are in contact.

[0103] Additionally, the stacking member (170) can be formed to be in contact with the hatch coaming (not shown in the drawing) or the lower cell guide (31) of the cargo hold (17) when the container loading assist device (100) is installed at the entrance of the cargo hold (17), and can be extended to the lower part of the protruding member (120).

[0104] By configuring the stacking member (170) as described above, the container loading assist device (100) can be stably fixedly installed at the entrance of the cargo hold (17), and when the container loading assist device (100) is raised between the top bridges (20) to install or remove it, it comes into contact with the upper cell guide (32), thereby stably guiding the raising and lowering.

[0105]

[0106] The container loading assist device (100) configured as described above can be guided by the upper cell guide (32) when moving between adjacent top bridges (20) by a crane (CR).

[0107] Additionally, the container loading assist device (100) can be stored by stacking it between outer vertical members (21a) facing each other in the front-rear direction on the upper deck (11) on the left or right side of the hull (10) during container unloading operations or before container loading operations, and, although not shown, can be stored by stacking it between intermediate vertical members (21b) facing each other in the front-rear direction, and, of course, can be stored by stacking it between two or more vertical members (21) even when two or more container loading assist devices (100) are connected in parallel. In this way, by stacking and storing the container loading assist device (100) on the container carrier (1), a separate storage place on land is not required, and the unloading efficiency of the container (C) can be improved.

[0108] In the present invention, the container carrier (1) is connected to lower cell guides (31) installed at regular intervals on the sides of the transverse bulkhead (16) within the cargo hold (17) and upper cell guides (32) installed on the top bridge (20) corresponding thereto. While the ability to continuously load containers (C) from the bottom of the cargo hold (17) to the top of the upper deck (11) may be similar to the open-top of a conventional small container carrier, the container carrier (1) of the present invention can load containers (C) in large quantities of 13 layers or more, including the amount loaded from the bottom of the cargo hold (17) to the top of the upper deck (11), due to the role of the container loading assist device (100) located in the center of the cell guides (31, 32), the top bridge (20) installed on the upper deck (11), and the upper cell guides (32).

[0109]

[0110] Hereinafter, a method for unloading a container using a container loading assist device (100) on a container carrier (1) according to the first embodiment of the present invention will be described with reference to FIG. 9 (a) to (c).

[0111] First, the operation of loading a container (C) on land onto a container carrier (1) using a crane (CR) is described. A spreader (SR) may be attached to the crane (CR). The crane (CR) can transport the container (C) and the container loading aid (100) using the attached spreader (SR).

[0112] The operation of loading the container (C) into the cargo hold (17) using a crane (CR) is performed to complete the loading of the container (C) into the cargo hold (17).

[0113] A crane (CR) is used to mount the container loading aid (100) at any position on the cargo hold (17).

[0114] At this time, the container loading aid (100) is transferred to the cargo hold (17) of the container carrier (1) using a crane (CR) while stored on land.

[0115] Afterwards, the operation of loading the container (C) onto the upper part of the container loading assist device (100) using a crane (CR) is performed, and the loading of the container (C) onto the upper part of the container loading assist device (100) is completed.

[0116] Below, the operation of unloading a container (C) of a container ship (1) onto land using a crane (CR) is described.

[0117] First, a crane (CR) is used to unload a container (C) loaded on top of a container loading aid (100).

[0118] Next, the container loading aid (100) is removed from the entrance of the cargo hold (17) using a crane (CR), thereby opening the entrance of the cargo hold (17).

[0119] Afterwards, the operation of unloading the container (C) loaded inside the cargo hold (17) is performed using a crane (CR).

[0120]

[0121] FIG. 10 is a drawing for explaining a container loading assist device provided on a container carrier according to a second embodiment of the present invention, and FIG. 11 (a) and (b) are drawings for explaining the process of operating the container loading assist device provided on a container carrier according to a second embodiment of the present invention as a spreader.

Here, the first specification may be, for example, the specification of a 40ft container among the 20ft container, 40ft container, and 45ft container mainly loaded on a container carrier (1). Accordingly, the container (C1) of the first specification may be a 40ft container and may correspond to the container (C1) shown in FIG. 21, which will be described later.

[0124] A container loading assist device (100) provided on a container carrier (1) according to a second embodiment has a size corresponding to a first standard and is applied to at least one cargo hold (17) and mounted on the hull (10), and can transfer the load of a container (C) loaded upward to the hull (10).

[0125] Additionally, the container loading assist device (100) provided on the container carrier (1) according to the second embodiment may further include a first fitting member (141) provided at the corner and on which the corner of a container (C1) of the first size is seated, and an inner fitting member (143) disposed inside the first fitting member (141) and provided to correspond to a third size smaller than the first size. Here, the third size may be the size of a 20ft container when the first size corresponds to the size of a 40ft container.

[0126] This container loading assist device (100) may further include a second fitting member (142) provided in the center in the front-rear direction.

[0127] In the above, the inner fitting member (143) may be positioned between the first fitting member (141) and the second fitting member (142).

[0128] The container loading assist device (100) of the second embodiment is provided on the exterior of the container carrier (1) as illustrated in FIG. 11 (a) and (b) and can be lifted by a spreader (SR) attached to a crane (CR). In this embodiment, the spreader (SR) may be a spreader having a telescoping function that can be expanded to a first size and reduced to a third size.

[0129] At this time, the container loading assist device (100) of the second embodiment can be lifted with the first fitting member (141) fastened by a spreader (SR) expanded to the first standard, as shown in FIG. 11 (a).

[0130] In addition, the container loading assist device (100) of the second embodiment can be lifted with the inner fitting member (143) fastened by a spreader (SR) reduced to a third size, as shown in (b) of FIG. 11.

[0131] The first fitting member (141) is provided at each corner of the container loading aid (100) and can be positioned at a location corresponding to the first standard.

[0133] In the above, the third specification has a width equal to the first specification and a length that is half that of the first specification.

[0134] As described above, the container loading assist device (100) of the second embodiment is further provided with an inner fitting member (143) between the first fitting member (141) and the second fitting member (142), so that the container loading assist device (100) can be lifted with the inner fitting member (143) fastened by a spreader (SR) reduced to the third size, thereby eliminating the possibility of interference with the twistlock for load measurement when lifting the container loading assist device (100) and eliminating the problem of interference with the upper cell guide (32) when using a crane (CR) with a width of 40 ft.

[0135]

[0136] FIGS. 12 and FIGS. 13 are drawings for explaining a container loading assist device provided on a container carrier according to a third embodiment of the present invention.

[0137] A container carrier (1) according to the third embodiment may include, as described above, a hull (10) formed by a side plate (12) forming a double hull structure with a side outer plate (12a) and a side inner plate (12b), a bottom plate (13) forming a double bottom structure with a bottom outer plate (13a) and a bottom inner plate (13b), and an upper deck (11), a cargo hold (17) partitioned by a transverse bulkhead (16) inside the hull (10), a lower cell guide (31) installed at regular intervals on the transverse bulkhead (16), and a top bridge (20) provided on the upper deck (11) and having an upper cell guide (32) that forms a guide path for a container (C).

[0138] The lower cell guide (31) may have a specification for loading a container (C1) of the first specification. Here, the first specification may be, for example, the specification of a 40ft container among the 20ft container, 40ft container, and 45ft container mainly loaded on a container carrier (1). Accordingly, the container (C1) of the first specification may be a 40ft container and may correspond to the container (C1) shown in FIG. 21, which will be described later.

[0139] A container loading assist device (100) provided on a container carrier (1) according to the third embodiment has a size corresponding to the first standard and is applied to at least one cargo hold (17) and mounted on the hull (10), and can transfer the load of a container (C) loaded upward to the hull (10).

[0140] In addition, the container loading assist device (100) provided on the container carrier (1) according to the third embodiment may include a spraying unit (180) for spraying a fire extinguishing liquid toward the interior of the cargo hold (17), as shown in FIGS. 12 and 13.

[0141] Referring to FIGS. 12 and 13, the spraying unit (180) may include a connecting end (181) mounted inside the container loading aid (100), pipes (182, 182a, 182b, 182c) and nozzles (183, 183a, 183b, 183c), and a fire extinguishing liquid supply unit (184) and supply line (185) provided on the upper deck (11) of the hull (10).

[0142] The connecting section (181) can be provided as a pair on the front and rear sides of the container loading aid (100) that spans the upper deck (11) of the hull (10).

[0143] A pair of connecting terminals (181) allow at least one of them to be connected to a supply line (185) to supply fire extinguishing liquid to a pipe (182, 182a, 182b, 182c) in which a nozzle (183, 183a, 183b, 183c) is provided.

[0144] That is, a pair of connecting terminals (181) can both be connected to the supply line (185).

[0145] Additionally, of the pair of connecting ends (181), only one of the connecting ends (181) may be connected to the supply line (185). At this time, the other connecting end (181) that is not connected to the supply line (185) is sealed with a stopper (not shown) to prevent leakage of the extinguishing liquid supplied through the supply line (185).

[0146] These pairs of connecting ends (181) are kept sealed by plugs when the container loading aid (100) is stored or not connected to the supply line (185).

[0147] Pipes (182, 182a, 182b, 182c) can have both ends connected to a pair of connecting ends (181) and can supply fire extinguishing liquid supplied from a fire extinguishing liquid supply unit (184) to nozzles (183, 183a, 183b, 183c).

[0148] The nozzles (183, 183a, 183b, 183c) can be arranged along the length of the pipes (182, 182a, 182b, 182c) and can spray the fire extinguishing liquid supplied to the pipes (182, 182a, 182b, 182c) into the interior of the cargo hold (17).

[0149] The extinguishing liquid supply unit (184) can be supplied through a supply line (185) to a pipe (182, 182a, 182b, 182c) equipped with a nozzle (183, 183a, 183b, 183c). At this time, the supply line (185) can be connected to at least one of a pair of connecting ends (181).

[0150] In this embodiment, the connecting end (181), pipe (182, 182a, 182b, 182c) and nozzle (183, 183a, 183b, 183c) of the spraying unit (180) mounted inside the container loading assist device (100) can be configured to be symmetric with respect to the centerline in the width direction of the container loading assist device (100), and accordingly, when arranging the container loading assist device (100) in the cargo hold (17), it can be arranged without considering left-right directionality, thereby making installation work easier.

[0151] In addition, the connecting end (181), pipe (182, 182a, 182b, 182c) and nozzle (183, 183a, 183b, 183c) mounted inside the container loading assist device (100) can be detached from the container loading assist device (100) to facilitate maintenance, as well as to facilitate replacement when broken or damaged.

[0152] The spraying unit (180) provided in the container loading assist device (100) may have different configurations as shown in FIG. 12 and FIG. 13. Hereinafter, the spraying unit (180) shown in FIG. 12 will be referred to as the spraying unit (180) having a first configuration, and the spraying unit (180) shown in FIG. 13 will be referred to as the spraying unit (180) having a second configuration.

[0153] As shown in FIG. 12, the spraying unit (180) having the first configuration may have a pipe (182) arranged along the length centerline of the container loading aid (100). At this time, a nozzle (183) may be arranged along the length direction of the pipe (182) and configured to spray fire extinguishing liquid vertically downward. Both ends of the pipe (182) may be connected to a pair of connecting ends (181) and may supply fire extinguishing liquid supplied from a fire extinguishing liquid supply unit (184) to the nozzle (183).

[0154] Additionally, the injection unit (180) having the second configuration may include, as shown in FIG. 13, a pipe (182) that is positioned along the length centerline of the container loading aid (100), a left pipe (182b) positioned to the left of the central pipe (182a), and a right pipe (182c) positioned to the right of the central pipe (182a).

[0155] At this time, the nozzle (183) may include a central nozzle (183a) arranged along the length direction of the central pipe (182a) and configured to spray fire extinguishing liquid vertically downward, a left nozzle (183b) arranged along the length direction of the left pipe (182b) and configured to spray fire extinguishing liquid downward to the left, and a right nozzle (183c) arranged along the length direction of the right pipe (182c) and configured to spray fire extinguishing liquid downward to the right.

[0156] The central pipe (182a), the left pipe (182b), and the right pipe (182c) can be configured in parallel in the container loading aid (100). Both ends of the parallel pipes (182, 182a, 182b, 182c) can be connected to a pair of connecting ends (181), and fire extinguishing liquid supplied from the fire extinguishing liquid supply unit (184) can be supplied to the nozzles (183a, 183b, 183c).

[0157] In this embodiment, a container loading assist device (100) including a spraying unit (180) having a first configuration or a second configuration is referred to as the first container loading assist device (100a), and a container loading assist device (100) of the aforementioned other embodiment in which the spraying unit (180) is omitted is referred to as the second container loading assist device (100b). Depending on whether the spraying unit (180) provided in the first container loading assist device (100a) is the first configuration or the second configuration, the arrangement in the cargo hold (17) may differ, as will be explained below.

[0158] Referring to FIG. 12, when a first container loading assist device (100a) having a spraying unit (180) of the first configuration is arranged in a cargo hold (17), the first container loading assist device (100a) is arranged along the left and right directions of the hull (10) in the cargo hold (17), and the arrangement of the second container loading assist device (100b) can be omitted. This arrangement is done to ensure an even distribution of the fire extinguishing liquid sprayed into the interior of the cargo hold (17), as the spraying unit (180) of the first configuration can only spray the fire extinguishing liquid vertically downward.

[0159] Referring to FIG. 13, when a first container loading assist device (100a) equipped with a spraying unit (180) of the second configuration is arranged in a cargo hold (17), the first container loading assist device (100a) and the second container loading assist device (100b) can be arranged alternately along the left and right directions of the hull (10) in the cargo hold (17). Arranging them in this way allows the spraying unit (180) of the second configuration to spray the fire extinguishing liquid not only vertically downward but also to the right downward and left downward directions, thereby enabling the fire extinguishing liquid to be sprayed evenly not only in the cargo hold (17) below the first container loading assist device (100a) but also in the cargo hold (17) below the second container loading assist device (100b) where the spraying unit (180) is omitted.

[0160]

[0161] FIGS. 14 and 15 are drawings for explaining a container loading assist device provided on a container carrier according to a fourth embodiment of the present invention.

[0162] A container carrier (1) according to the fourth embodiment may include, as described above, a hull (10) comprising a side plate (12) forming a double hull structure with a side outer plate (12a) and a side inner plate (12b), a bottom plate (13) forming a double bottom structure with a bottom outer plate (13a) and a bottom inner plate (13b), and an upper deck (11); a cargo hold (17) partitioned by a transverse bulkhead (16) inside the hull (10); a lower cell guide (31) installed at regular intervals on the transverse bulkhead (16); and a top bridge (20) provided on the upper deck (11) and having an upper cell guide (32) that forms a guide path for a container (C).

[0163] The lower cell guide (31) may have a specification for loading a container (C1) of the first specification. Here, the first specification may be, for example, the specification of a 40ft container among the 20ft container, 40ft container, and 45ft container mainly loaded on a container carrier (1). Accordingly, the container (C1) of the first specification may be a 40ft container and may correspond to the container (C1) shown in FIG. 21, which will be described later.

[0164] A container loading assist device (100) provided on a container carrier (1) according to the fourth embodiment has a size corresponding to the first standard and is applied to at least one cargo hold (17) and mounted on the hull (10), and can transfer the load of a container (C) loaded on top to the hull (10).

[0165] Additionally, the container loading assist device (100) provided on the container carrier (1) according to the fourth embodiment may be arranged in a plurality along the left and right directions of the hull (10) in the cargo hold (17), and as shown in FIGS. 14 and 15, the plurality of container loading assist devices (100) may further include a sealing member (190) provided on a surface facing each other to suppress the inflow of foreign matter into the cargo hold (17). This sealing member (190) may be formed of rubber, a composite material, or a similar material for watertightness on the side of the container loading assist device (100).

[0166] A sealing member (190) provided in a container loading assist device (100) may have a different configuration as shown in FIG. 14 and FIG. 15. Hereinafter, the sealing member (190) shown in FIG. 14 will be described as a sealing member (190) having a first configuration, and the sealing member (190) shown in FIG. 15 will be described as a sealing member (190) having a second configuration.

[0167] A sealing member (190) having a first configuration may include a first sealing member (191) provided on the left side of the container loading assist device (100), as shown in FIG. 14, and a second sealing member (192) provided on the right side of the container loading assist device (100) and symmetrically provided with respect to the first sealing member (191).

[0168] That is, the container loading assist device (100) of the fourth embodiment may include a first sealing member (191) and a second sealing member (192) arranged symmetrically on the left and right sides.

[0169] In the fourth embodiment, when a plurality of container loading aids (100) having a sealing member (190) of the first configuration are arranged in a cargo hold (17), the first sealing member (191) and the second sealing member (192) provided in two adjacent container loading aids (100) can suppress the inflow of foreign matter into the cargo hold (17) on surfaces facing each other.

[0170] Additionally, the sealing member (190) having the second configuration may include a third sealing member (193) provided at a left side point of the container loading assist device (100) as shown in FIG. 15, and a fourth sealing member (194) provided at a right side point of the container loading assist device (100) but arranged so as to be offset from the third sealing member (193).

[0171] That is, the container loading assist device (100) of the fourth embodiment may include a third sealing member (193) and a fourth sealing member (194) provided at one point on the left and another point on the right.

[0172] In the fourth embodiment, when a plurality of container loading aids (100) having a sealing member (190) of the second configuration are arranged in a cargo hold (17), the third sealing member (193) and the fourth sealing member (194) provided in two adjacent container loading aids (100) can prevent foreign substances from entering the cargo hold (17) from facing each other in a mutually offset manner.

[0173] In the above, the point on the left where the third sealing member (193) is provided may be 180 degrees rotationally symmetrical with respect to the other point on the right where the fourth sealing member (194) is provided.

[0174] The third sealing member (193) may be provided on the left side of the container loading aid (100) in a portion of the front and rear.

[0175] The fourth sealing member (194) may be provided in the right side of the container loading aid (100), in the front and rear portions.

[0176] As described above, in the fourth embodiment, when the container loading assist device (100) is arranged in the cargo hold (17), the inflow of foreign matter into the cargo hold (17) can be suppressed by a sealing member (190) having the first configuration or the second configuration.

[0177] However, the sealing member (190) having the first configuration or the second configuration can only seal the second gap (G2) that is formed in the part where the container loading assist device (100) comes into contact, but in the case of the container loading assist device (100) placed at the left and right ends of the entrance of the cargo hold (17), a first gap (G1) larger than the second gap (G2) is formed from the hull (10), so it cannot prevent foreign matter from entering the cargo hold (17) in this part (see FIG. 33).

[0178] Accordingly, as will be described later with reference to FIGS. 31 to 35, an auxiliary coaming member (72) protruding to face a container loading assist device (100) positioned at a location spaced apart from the left and right sides of the entrance of the cargo hold (17) is provided above the coaming member (71), thereby suppressing foreign substances entering the cargo hold (17) together with the sealing member (190) of the container loading assist device (100) between the container loading assist device (100) and the entrance of the cargo hold (17).

[0179] At this time, the auxiliary coaming member (72) is positioned such that its upper portion is adjacent to one side of the container loading assist device (100), and although not shown, it is positioned below the sealing member (190) so that when it flows from the upper surface of the container loading assist device (100) to the auxiliary coaming member (72) through the sealing member (190), it does not flow into the cargo hold (17).

[0180]

[0181] FIGS. 16 to 19 are drawings for explaining a storage system for storing a container loading aid of the present invention.

[0182] The storage system (200) can store the container loading aid (100) on land or on a container carrier (1), and can be configured to stack them in a row on land or on a container carrier (1) and operate them conveniently with a crane (CR).

[0183] The storage system (200) may be configured to store a container loading aid (100) used in a container carrier (1), comprising a cargo hold (17) partitioned by a transverse bulkhead (16) inside the hull (10), a lower cell guide (31) installed on the transverse bulkhead (16), and a bridge provided on the upper part of the hull (10).

[0184] In the above, the term "bridge" may be used to encompass various bridges, such as the aforementioned top bridge (20), the first deck bridge (20a) to be described later, and the first composite bridge (20b) to be described later.

[0185] In the above, the container loading assist device (100) is applied to the cargo hold (17) to be mounted on the hull (10) as described above, and may include a protruding member (120) that is mounted on the upper deck (11) of the hull (10) and protrudes in the forward and backward directions.

[0186] The storage system (200) may include a frame (210), a guide member (220), an entry guide (230), a fixing member (240), and a ladder (250).

[0187] The frame (210) can be configured to form a space capable of accommodating the container loading aid (100) in multiple stages.

[0214] The rotating part (42) can maintain a rotating state in the direction outside the cargo hold (17) when the container (C1) of the first standard is loaded inside the cargo hold (17).

[0215] Additionally, the rotating part (42) can be rotated in the direction of the inside of the cargo hold (17) so that at least a part of the container loading assist device (100) being inserted is mounted, before the container loading assist device (100) is inserted into the upper cell guide (32) after the container (C1) of the first standard is loaded into the cargo hold (17).

[0216] In the fifth embodiment, a container of the first size (C1) can be loaded inside the hull (10) which is the lower part of the container loading assist device (100), and on the upper part of the container loading assist device (100), as shown in FIGS. 20, 22 to 25, a container of the first size (C1) and a container of the second size (C2) can be loaded in various ways.

[0217] That is, as shown in FIG. 20, only a container of the second standard (C2) can be loaded on the upper part of the container loading aid (100).

[0218] As shown in FIG. 22, a container of the second size (C2) can be partially loaded on the upper part of the container loading aid (100), and a container of the first size (C1) can be loaded on the upper part.

[0219] As shown in FIG. 23, a container (C1) of the first size can be partially loaded on the upper part of the container loading aid (100), and a container (C2) of the second size can be loaded on the upper part.

[0220] As shown in FIG. 24, only a container (C1) of the first standard can be loaded on the upper part of the container loading aid (100).

[0221] That is, in this embodiment, only a container of the first size (C1) may be loaded on the upper part of the container loading aid (100), only a container of the second size (C2) may be loaded, or a mixture of a container of the first size (C1) and a container of the second size (C2) may be loaded.

[0222] The container loading assist device (100) may include a first fitting member (141) provided at the corner as described above.

[0223] When a container (C1) of the first size is placed on the container loading assist device (100) described above, the corner casting (C11) of the container (C1) of the first size is seated on the first fitting member (141) to fix the container (C1) of the first size.

[0224] When a container of the second size (C2) is placed on the container loading assist device (100) described above, the auxiliary corner casting (C22) of the container of the second size (C2) is seated on the first fitting member (141) to secure the container of the second size (C2).

[0225] When a container of the first size (C1) and a container of the second size (C2) are stacked, an auxiliary corner casting (C22) of the container of the second size (C2) is seated on the first fitting member (141) of the container of the first size (C1) so that the container of the first size (C1) and the container of the second size (C2) can be fixed to each other.

[0226] In addition, the container carrier (1) according to the fifth embodiment may further include a stool member (50) provided on the upper deck (11) on the front and rear side of the entrance of the cargo hold (17), as shown in FIG. 25, and configured to support at least a portion of a container (C2) of the second standard.

[0227] The stool member (50) may include a stool (not shown in the drawing) fixed to the upper deck (11) and a projection (not shown in the drawing) provided on the upper surface of the stool at a position corresponding to the main corner casting (C21) of the second standard container (C2).

[0228] When a container (C2) of the second size is loaded onto the upper surface of the container loading aid (100), the main corner casting (C21) of the container (C2) of the second size is seated on the protrusion, thereby securing the container (C2) of the second size.

[0229] The above-mentioned stool member (50) may be provided with a height equal to or higher than the height of the container loading aid (100).

[0230] When the height of such a stool member (50) is the same as the height of the container loading assist device (100), it can be mounted on the hull (10) together with the container loading assist device (100) to distribute the load of the container (C) loaded upward and transfer it to the hull (10).

[0231] Additionally, if the height of the stool member (50) is higher than the height of the container loading aid (100), it can be mounted on the hull (10) and directly transfer the load of the container (C) loaded upward to the hull (10).

[0232] Additionally, the container carrier (1) according to the fifth embodiment may further include a lashing member (23) for securing a container (C) loaded on top of a container loading aid (100).

[0233] The lashing member (23) can secure a container (C1) of the first size to the first deck bridge (20a) when the container (C) loaded on the top of the container loading aid (100) is of the first size.

[0234] When the container (C) loaded on the top of the container loading aid (100) is of the second size, the container (C2) of the second size is fixed by the upper cell guide (32), so the lashing member (23) is unnecessary.

[0235] In the container carrier (1) of the fifth embodiment, a first deck bridge (20a) may be installed on the upper deck (11) on the front and rear sides of a plurality of cargo holds (17).

[0236] In addition, the container carrier (1) of the fifth embodiment may have a first deck bridge (20a) installed on the upper deck (11) on the front and rear sides of at least one of the cargo holds (17), and the top bridge (20) of the first embodiment described above may be installed on the upper deck (11) on the front and rear sides of the remaining cargo holds (17).

[0237] That is, the container carrier (1) according to the fifth embodiment may have only the first deck bridge (20a) or may have the top bridge (20) of the first embodiment mixed in.

[0238] The first deck bridge (20a) may be different from the top bridge (20) of the first embodiment. However, the first deck bridge (20a) may be interpreted as the top bridge (20).

[0239] The top bridge (20) of the first embodiment may be installed extending to the left and right edges of the upper deck (11) between the cargo holds (17) as described above, and may be arranged at a certain distance from the bow (14) to the stern (15). The top bridge (20) arranged in the forward and backward direction may be composed of a combination of a plurality of vertical members (21) and a plurality of horizontal members (22), wherein the width of the plurality of vertical members (21) may be the same as the width of the upper deck (11) between adjacent cargo holds (17).

[0240] In addition, the top bridge (20) of the first embodiment has upper cell guides (32) installed on both sides that are integrally connected with lower cell guides (31) to form a continuous guide path for a container (C1) of the first standard.

[0241] The first deck bridge (20a) may have the same or similar overall configuration compared to the top bridge (20) of the first embodiment, but the width of the plurality of vertical members (21) may be narrower than the width of the upper deck (11) between adjacent cargo holds (17). The first deck bridge (20a) will be described in detail below.

[0242] A first deck bridge (20a) may be provided on an upper deck (11) between a plurality of cargo holds (17), as illustrated in FIGS. 20, 22 to 25. On one side of the first deck bridge (20a), an upper cell guide (32) may be formed on a side adjacent to the first cargo hold (17) among the plurality of cargo holds (17) but not integrally connected to a lower cell guide (31), and on the other side of the first deck bridge (20a), an upper cell guide (32) may be formed on a side adjacent to the second cargo hold (17) adjacent to the first cargo hold (17) but integrally connected to a lower cell guide (31) to form a continuous guide path.

[0243] A first deck bridge (20a) provided on the upper deck (11) on the front and rear side of at least one of the multiple cargo holds (17) may have a portion of the upper deck (11) exposed in the part where the lower cell guide (31) and the upper cell guide (32) are not connected, and a hinge member (40) and / or a stool member (50), etc. may be provided on the exposed upper deck (11).

[0244] In the container carrier (1) of the fifth embodiment, when the first deck bridge (20a) and the top bridge (20) of the first embodiment are arranged to be mixed, a second-sized container (C2) larger than a first-sized container (C1) can be loaded between the first deck bridges (20a) facing each other, and a first-sized container (C1) can be loaded between the first deck bridge (20a) and the adjacent top bridge (20) and between the top bridges (20) facing each other.

[0245] In addition, in the container carrier (1) of the fifth embodiment, when only the first deck bridge (20a) is applied, a second-sized container (C2) larger than a first-sized container (C1) can be loaded between the first deck bridges (20a) facing each other at the part where the lower cell guide (31) and the upper cell guide (32) are misaligned, and a first-sized container (C1) can be loaded between the first deck bridges (20a) facing each other at the part where the lower cell guide (31) and the upper cell guide (32) are connected to form a continuous guide path.

[0246] As mentioned above, the first deck bridge (20a) can be installed on the upper deck (11) such that, among the upper cell guides (32) installed on the front and rear sides, the upper cell guide (32) installed on the rear side is connected to the lower cell guide (31) installed inside the cargo hold (17) and is formed as a single unit, and the upper cell guide (32) installed on the front side is configured to be misaligned with the lower cell guide (31) installed inside the cargo hold (17), so that a part of the upper deck (11) is exposed at the part where the lower cell guide (31) and the upper cell guide (32) are misaligned.

[0247] In other words, in the fifth embodiment, one first deck bridge (20a) and another first deck bridge (20a) can be arranged so that a second-sized container (C2) larger than a first-sized container (C1) can be loaded between the first deck bridge (20a) installed on the upper deck (11) on the rear side of the entrance of one cargo hold (17) and the other first deck bridge (20a) installed on the upper deck (11) on the front side of the entrance of one cargo hold (17), so that a portion of the upper deck (11) that is exposed faces each other.

[0248] That is, if one first deck bridge (20a) is installed on the upper deck (11) such that the rear upper cell guide (32) is positioned on an extension line with the lower cell guide (31) provided in the rear cargo hold (17) based on one cargo hold (17), and the front upper cell guide (32) is positioned off-center from the lower cell guide (31) provided in the cargo hold (17), then another first deck bridge (20a) can be installed on the upper deck (11) such that the rear upper cell guide (32) is positioned off-center from the lower cell guide (31) provided in the cargo hold (17), and the front upper cell guide (32) is positioned on an extension line with the lower cell guide (31) provided in the front cargo hold (17) based on one cargo hold (17).

[0249] One of these first deck bridges (20a) and another first deck bridge (20a) positioned adjacent to it form a basic structure for loading a second-sized container (C2) larger than a first-sized container (C1).

[0250] When the first deck bridge (20a) and the top bridge (20) of the first embodiment are arranged in a mixed manner, the first deck bridge (20a) is arranged in a basic structure consisting of one first deck bridge (20a) and another first deck bridge (20a), and at least one basic structure may be arranged, and at least one top bridge (20) of the first embodiment may be arranged in front of or behind the basic structure of the first deck bridge (20a).

[0251] The arrangement of the first deck bridge (20a) and the top bridge (20) of the first embodiment can be varied, for example, by repeating the arrangement in the order of one first deck bridge (20a), another first deck bridge (20a), and the top bridge (20), or by repeating the arrangement of one first deck bridge (20a) and another first deck bridge (20a) at least twice, and repeating the arrangement of the top bridge (20) at least once between the repeated first deck bridges (20a).

[0252] The width between one first deck bridge (20a) and another first deck bridge (20a) can correspond to the width of a second-sized container (C2) that is larger than a first-sized container (C1). That is, the width between one first deck bridge (20a) and another first deck bridge (20a) can be a width that allows the second-sized container (C2) to be raised and lowered by being supported by upper cell guides (32) facing each other on both sides of the second-sized container (C2).

[0253] In addition, in the section where a basic structure consisting of one first deck bridge (20a) and another first deck bridge (20a) is arranged in succession, the width between the other first deck bridge (20a) on the front side of the basic structure and the one first deck bridge (20a) on the rear side of the adjacent basic structure can correspond to the width of a first-size container (C1) that is smaller than a second-size container (C2). That is, the width between the other first deck bridge (20a) on the front side of the basic structure and the one first deck bridge (20a) on the rear side of the adjacent basic structure can be a width that allows the first-size container (C1) to be raised and lowered by being supported by upper cell guides (32) facing each other on both sides of the first-size container (C1).

[0254] In addition, in the part where the top bridge (20) of the first embodiment is arranged adjacent to the basic structure consisting of one first deck bridge (20a) and another first deck bridge (20a), the width between the first deck bridge (20a) of the basic structure and the top bridge (20) can correspond to the width of the first standard container (C1), which is smaller than the second standard container (C2). That is, the width between the first deck bridge (20a) of the basic structure and the top bridge (20) can be a width that allows the first standard container (C1) to be raised and lowered by being supported by the upper cell guide (32) facing both sides of the first standard container (C1).

[0255] In addition, in the portion where the top bridges (20) of the first embodiment are arranged continuously, the width between the front top bridge (20) and the rear top bridge (20) can correspond to the width of the first standard container (C1), which is smaller than the second standard container (C2). That is, the width between the front top bridge (20) and the rear top bridge (20) can be a width that allows the first standard container (C1) to be raised and lowered by being supported by the upper cell guide (32) facing both sides of the first standard container (C1).

[0256] As mentioned above, the first deck bridge (20a) of the fifth embodiment is configured such that the upper cell guide (32) installed on the rear side among the upper cell guides (32) installed on the front and rear sides is connected to the lower cell guide (31) installed inside the cargo hold (17) and is formed as a single unit, and the upper cell guide (32) installed on the front side is configured to be offset from the lower cell guide (31) installed inside the cargo hold (17). Of course, a second deck bridge (not shown) of another embodiment of such a first deck bridge (20a) can also be applied to a container carrier (1).

[0257] Unlike the first deck bridge (20a) shown in FIGS. 20, 22 to 25, the second deck bridge may be provided on the upper deck (11) between a plurality of cargo holds (17). On one side of the second deck bridge, an upper cell guide (32) may be formed on the side adjacent to the first cargo hold (17) among the plurality of cargo holds (17) but not integrally connected to the lower cell guide (31), and on the other side of the second deck bridge, an upper cell guide (32) may be formed on the side adjacent to the second cargo hold (17) adjacent to the first cargo hold (17) but not integrally connected to the lower cell guide (31).

[0258] Accordingly, the second deck bridge has both sides of the upper deck (11) exposed, and hinge members (40) and / or stool members (50), etc., can be provided on both sides of the upper deck (11) that are exposed.

[0259]

[0273] The third container loading aid (100c) can be distinguished by color to distinguish between the container loading aid (100) of the above-described embodiment, which has a size corresponding to the first standard container (C1), and the third container loading aid (100c) of the sixth embodiment, which has a size corresponding to the second standard container (C2).

[0274] For example, the third container loading aid (100c) can be identified by marking the inner part of the first fitting member (141), which is provided adjacent to the upper corner of the main body (110c) corresponding to the container loading aid (100) of the above-described embodiment, with a first color (yellow), and marking the space between the outer fitting member (144), which is provided adjacent to the upper corner of the main body (110c) corresponding to the third container loading aid (100c) of the sixth embodiment, and the first fitting member (141), which is provided adjacent to the upper corner of the main body (110c), with a second color (blue) different from the first color.

[0275] In the third container loading assist device (100c), the configuration of the first color portion is identical or similar to the configuration of the container loading assist device (100) of the previously described embodiment, so a detailed description is omitted here to avoid redundant explanation, and the configuration of the second color portion may be configured as follows: as mentioned above, the first watertight plate (153a), the second watertight plate (153b), and the third watertight plate (153c) are further extended outward from the first fitting member (141) to correspond to the size of the second standard container (C2), and the outer fitting member (144) is provided in the extended corner portion so that the main corner casting (C21) of the second standard container (C2) is seated.

[0276] The third container loading assist device (100c) configured in this manner can transfer the load of a first-size container (C1) or a second-size container (C2) loaded upward to the hull (10) by mounting a portion extending outward from the first fitting member (141) on the hull (10) as shown in FIGS. 27 and 28.

[0277] As illustrated in FIG. 27, when a container of the second size (C2) is placed on a third container loading aid (100c), the auxiliary corner casting (C22) of the container of the second size (C2) is seated on the first fitting member (141), and the main corner casting (C21) of the container of the second size (C2) is seated on the outer fitting member (144), thereby securing the container of the second size (C2).

[0278] Additionally, as shown in FIG. 28, when a container of the first size (C1) is placed on the third container loading aid (100c), the corner casting (C11) of the container of the first size (C1) is seated on the first fitting member (141) to secure the container of the first size (C1).

[0279]

[0280] Hereinafter, the aforementioned container loading assist device (100) will be described as a container loading assist device (100) for a first standard having a size corresponding to a first standard and a main body (110) in the shape of a rectangular box, and the third container loading assist device (100c) of the present embodiment will be described as a container loading assist device (100c) for a second standard having a size corresponding to a second standard larger than the first standard and a main body (110c) in the shape of a rectangular box.

[0281] As described above, the first standard container loading assist device (100) may include a first fitting member (141) provided at the upper corner of the main body (110) and on which the corner of the first standard container (C1) is seated, a second fitting member (142) provided at the center in the front-rear direction of the main body (110) and on which one corner of a third standard container (not shown) smaller than the first standard is seated, and a stacking member (170) extending directly downward from the first fitting member (141) and having a part protruding downward from the main body (110).

[0282] As shown in FIG. 26, the second standard container loading assist device (100c) may include a first fitting member (141) provided at the upper corner of the main body (110c) and on which the corner of a first standard container (C1) is seated, a second fitting member (142) provided at the center in the front-rear direction of the main body (110c) and on which one corner of a third standard container (not shown) smaller than the first standard is seated, and an outer fitting member (144) disposed on the outside of the first fitting member (141) and on which the corner of a second standard container (C2) larger than the first standard is seated.

[0283] In the above, the container of the third standard can correspond to the standard of a 20ft container when the container of the first standard (C1) corresponds to the standard of a 40ft container and the container of the second standard (C2) corresponds to the standard of a 45ft container.

[0284] The second standard container loading aid (100c), although not shown in FIG. 26, may further include a loading member (170) that extends downward from the first fitting member (141) in the same or similar manner as the first standard container loading aid (100) and has a portion protruding downward from the main body (110c).

[0285] When the second standard container loading aid (100c) is installed at the entrance of the cargo hold (17), the protruding part of this loading aid (170) comes into contact with the lower cell guide (31) inside the cargo hold (17), thereby allowing the second standard container loading aid (100c) to be fixed at the entrance of the cargo hold (17).

[0286] The stacking member (170) may include a stacking bridge (171) extending downward from the first fitting member (141), and a third fitting member (172) provided at the bottom of the stacking bridge (171) and connected to the first fitting member (141) provided on the second standard container stacking aid (100c) which is stacked on top when stacking the second standard container stacking aid (100c) in multiple layers.

[0287] The second standard container loading assist device (100c) configured as above can be installed such that the extended front and rear ends of the main body (110c), which extends to both sides from the first fitting member (141) to the outer fitting member (144), are supported on the upper deck (11) on the front and rear sides of the entrance of the cargo hold (17), and the ends are not supported on the upper deck (11) on the left and right sides of the entrance of the cargo hold (17).

[0288] In the above, as both ends of the second standard container loading aid (100c) are installed without being supported on the upper deck (11) on the left and right sides of the entrance of the cargo hold (17), a first gap (G1) may occur in this part as shown in FIG. 33, and foreign matter may flow into the interior of the cargo hold (17) through the first gap (G1).

[0289] Accordingly, a container carrier (1) equipped with a second-standard container loading aid (100c) may further include a coaming member (71) that is provided on the left and right sides of the entrance of the cargo hold (17) and protrudes upward from the upper deck (11), which is identical or similar to the eighth embodiment (Figs. 31 to 35) described later, and an auxiliary coaming member (72) that is provided above the coaming member (71) and protrudes to face the second-standard container loading aid (100c) which is positioned at a spaced-away position from the left and right sides of the entrance of the cargo hold (17) to suppress foreign substances flowing into the left and right sides of the cargo hold (17).

[0290] Additionally, when the second standard container loading aid (100c) is arranged along the left and right directions of the hull (10), a second gap (G2) may be created between adjacent second standard container loading aids (100c), as shown in FIG. 33, and foreign matter may be introduced into the interior of the cargo hold (17) through the second gap (G2).

[0291] Accordingly, the second standard container loading assist device (100c) may further include a sealing member (190) provided on a surface facing each other in the same or similar manner as the aforementioned fourth embodiment (Figs. 14 and 15) to suppress the inflow of foreign matter into the cargo hold (17).

[0292] These sealing members (190) can prevent foreign substances from entering the cargo hold (17) together with the auxiliary coaming member (72).

[0293] At this time, the auxiliary coaming member (72) may be positioned so that its upper portion is adjacent to one side of the second standard container loading auxiliary device (100c), and may be positioned below the sealing member (190).

[0294] The bridge provided on the upper deck (11), with one or both sides of the lower cell guide (31) offset from the upper deck, can be varied and will be described in detail below.

[0295] First, the bridge of the present embodiment may be a first deck bridge (20a) identical or similar to the aforementioned fifth embodiment (Figs. 20 to 25) which is installed on the upper deck (11) on the front and rear sides forming the entrance of the cargo hold (17).

[0296] As described above, the first deck bridge (20a) may be provided on the upper deck (11) between the plurality of cargo holds (17). On one side of the first deck bridge (20a), an upper cell guide (32) may be formed on the side adjacent to the first cargo hold (17) among the plurality of cargo holds (17) but not integrally connected to the lower cell guide (31), and on the other side of the first deck bridge (20a), an upper cell guide (32) may be formed on the side adjacent to the second cargo hold (17) adjacent to the first cargo hold (17) but integrally connected to the lower cell guide (31) to form a continuous guide path.

[0297] In the case where the bridge of the present embodiment is a first deck bridge (20a) configured as above, the container carrier (1) may be equipped with a first standard container loading assist device (100) and a second standard container loading assist device (100c) mixed together.

[0298] That is, the first standard container loading aid (100) can be installed at the entrance of the second cargo hold (17) in which the upper cell guide (32) is integrally connected with the lower cell guide (31) at the first deck bridge (20a).

[0299] The second standard container loading aid (100c) can be installed in any one of the cargo holds (17) in the first deck bridge (20a) where the upper cell guide (32) is not integrally connected with the lower cell guide (31).

[0300] In addition, the bridge of the present embodiment may be a second deck bridge (not shown) identical or similar to the aforementioned fifth embodiment (Figs. 20 to 25) which is installed on the upper deck (11) on the front and rear sides forming the entrance of the cargo hold (17).

[0302] In the case where the bridge of the present embodiment is a second deck bridge configured as above, the container carrier (1) may be equipped with a second standard container loading assist device (100c).

[0303] That is, the second standard container loading aid (100c) can be installed in the first cargo hold (17) and the second cargo hold (17) in which the upper cell guide (32) is not integrally connected with the lower cell guide (31) at the second deck bridge.

[0304] In addition, the bridge of this embodiment may be a first composite bridge (20b) identical or similar to the seventh embodiment (Fig. 29) described later, which is installed on the upper deck (11) on the front and rear sides forming the entrance of the cargo hold (17).

[0305] As will be described later, the first composite bridge (20b) may be provided on the upper deck (11) between a plurality of cargo holds (17). On one side of the first composite bridge (20b), an upper cell guide (32) may be formed, which is provided on the side adjacent to the first cargo hold (17) among the plurality of cargo holds (17) and is integrally connected with the lower cell guide (31) to form a continuous guide path. On the other side of the first composite bridge (20b), the upper cell guide (32) may be omitted on the side adjacent to the second cargo hold (17) that is adjacent to the first cargo hold (17). The side of the first composite bridge (20b) where the upper cell guide (32) is omitted may be located on the inner side of the upper deck (11) so as not to be offset from the lower cell guide (31).

[0306] In the case where the bridge of the present embodiment is a first composite bridge (20b) configured as described above, the container carrier (1) may be equipped with a first standard container loading assist device (100) and a second standard container loading assist device (100c) mixed together.

[0307] That is, the first standard container loading assist device (100) can be installed in the first cargo hold (17) in which the upper cell guide (32) is integrally connected with the lower cell guide (31) in the first composite bridge (20b), and the second standard container loading assist device (100c) can be installed in the second cargo hold (17).

[0308] Additionally, the bridge of the present embodiment may be a second composite bridge (not shown) identical or similar to the seventh embodiment (Fig. 29) described later, which is installed on the upper deck (11) on the front and rear sides forming the entrance of the cargo hold (17).

The side of the second composite bridge, in which the upper cell guide (32) is omitted, can be positioned on the inner side of the upper deck (11) so as to be offset from the lower cell guide (31).

[0309] In the case where the bridge of the present embodiment is a second composite bridge configured as above, the container carrier (1) may be equipped with a second standard container loading assist device (100c).

[0310] That is, the second standard container loading assist device (100c) can be installed in the first cargo hold (17) and the second cargo hold (17).

[0311] In addition, the bridge of this embodiment may be a lashing bridge (60) identical or similar to the seventh embodiment (Fig. 29) described later, which is installed on the upper deck (11) on the front and rear sides forming the entrance of the cargo hold (17).

[0312] As will be described later, the lashing bridge (60) may be provided on the upper deck (11) between the multiple cargo holds (17). On one side of the lashing bridge (60), the upper cell guide (32) may be omitted, provided on the side adjacent to the first cargo hold (17) among the multiple cargo holds (17), and on the other side of the second composite bridge (20b), the upper cell guide (32) may be omitted, provided on the side adjacent to the second cargo hold (17) adjacent to the first cargo hold (17). Both sides of the lashing bridge (60) where the upper cell guide (32) is omitted may be positioned on the inner side of the upper deck (11) so as to be offset from the lower cell guide (31).

[0313] In the case where the bridge of the present embodiment is a lashing bridge (60) configured as above, the container carrier (1) may be equipped with a second standard container loading assist device (100c).

[0314] That is, the second standard container loading assist device (100c) can be installed in the first cargo hold (17) and the second cargo hold (17).

[0315]

[0316] FIG. 29 is a drawing for explaining a container carrier according to the seventh embodiment of the present invention.

[0317] A container carrier (1) according to the 7th embodiment may include, as described above, a hull (10) comprising a side plate (12) forming a double hull structure with a side outer plate (12a) and a side inner plate (12b), a bottom plate (13) forming a double bottom structure with a bottom outer plate (13a) and a bottom inner plate (13b), and an upper deck (11), a cargo hold (17) partitioned by a transverse bulkhead (16) inside the hull (10), a lower cell guide (31) installed at regular intervals on the transverse bulkhead (16), and a first composite bridge (20b) provided on the upper deck (11) and having an upper cell guide (32) that forms a guide path for a container (C).

[0318] The first composite bridge (20b) applied to the container carrier (1) according to the seventh embodiment may differ in configuration from the top bridge (20) of the first embodiment described above.

[0319] That is, one side of the first composite bridge (20b) may be configured to be identical or similar to the structure in which the upper cell guide (32) is installed in the top bridge (20) of the first embodiment, and the upper cell guide (32) may be positioned at the edge of the upper deck (11) so as to be integrally connected with the lower cell guide (31) installed inside the cargo hold (17) to form a continuous guide path.

[0320] Additionally, the other side of the first composite bridge (20b) may be configured to be identical or similar to the structure of the top bridge (20) of the first embodiment in which the upper cell guide (32) is omitted, or the structure of the lashing bridge (60), and may be positioned on the inner side of the upper deck (11) so as to be offset from the lower cell guide (31) installed inside the cargo hold (17).

[0321] That is, the first composite bridge (20b) may be provided on the upper deck (11) between the plurality of cargo holds (17). On one side of the first composite bridge (20b), an upper cell guide (32) may be formed, which is provided on the side adjacent to the first cargo hold (17) among the plurality of cargo holds (17) and is integrally connected with the lower cell guide (31) to form a continuous guide path, and on the other side of the first composite bridge (20b), the upper cell guide (32) may be omitted on the side adjacent to the second cargo hold (17) adjacent to the first cargo hold (17). The side of the first composite bridge (20b) where the upper cell guide (32) is omitted may be located on the inner side of the upper deck (11) offset from the lower cell guide (31).

[0322] In this first composite bridge (20b), the upper cell guide (32) can support and fix the container (C) on the inner side where the upper cell guide (32) is provided, and the container (C) can be fixed by the lashing member (23) on the outer side where the upper cell guide (32) is omitted.

[0323] The first composite bridge (20b) configured as described above can be installed on the front upper deck (11) and the rear upper deck (11), respectively, forming the entrance of one of the cargo holds (17) among the plurality of cargo holds (17).

[0324] The first composite bridge (20b), which is installed on the front upper deck (11) and the rear upper deck (11) forming the entrance of the cargo hold (17), can be installed such that the inner surface facing it is aligned with the lower cell guide (31), and the outer surface of each is offset from the lower cell guide (31).

[0325] This first composite bridge (20b) can be installed in a section where many containers (C) can be loaded, because the upper cell guide (32) forming the facing inner surface can stably fix the container (C).

[0326] For example, the first composite bridge (20b) may be provided above the engine room (R) located at the rear of the cabin (A).

[0327] This first composite bridge (20b) may be different from the top bridge (20) of the first embodiment, but the first composite bridge (20b) can be interpreted as the top bridge (20).

[0328] Although it has been described above that the first composite bridge (20b) is installed on the front upper deck (11) and the rear upper deck (11), respectively, which form the entrance of one of the multiple cargo holds (17), it is obvious that it can be provided on the upper deck (11) which forms the entrance of at least one of the multiple cargo holds (17).

[0329] In addition, the container carrier (1) according to the seventh embodiment may further include a lashing bridge (60) provided on the upper deck (11) in addition to the first composite bridge (20b) described above, as shown in FIG. 29.

[0330] In this embodiment, the lashing bridge (60) may be provided on the upper deck (11) between a plurality of cargo holds (17). On one side of the lashing bridge (60), the upper cell guide (32) may be omitted, provided on the side adjacent to the first cargo hold (17) among the plurality of cargo holds (17), and on the other side of the second composite bridge (20b), the upper cell guide (32) may be omitted, provided on the side adjacent to the second cargo hold (17) adjacent to the first cargo hold (17). Both sides of the lashing bridge (60) where the upper cell guide (32) is omitted may be located on the inner side of the upper deck (11) offset from the lower cell guide (31).

[0331] This lashing bridge (60) may be made of a structure identical or similar to the structure in which the upper cell guides (32) provided on both sides of the aforementioned top bridge (20) are omitted, or may be made of a structure identical or similar to the existing lashing bridge that is generally widely applied.

[0332] The lashing bridge (60) can fix the container (C) by means of a lashing member (23) connected to the inner and outer surfaces where the upper cell guide (32) is omitted.

[0333] A lashing bridge (60) may be provided on the upper front and rear deck (11) forming the entrance of the remaining cargo holds (17), excluding the cargo hold (17) to which the first composite bridge (20b) is applied among the plurality of cargo holds (17).

[0334] Additionally, the container carrier (1) according to the seventh embodiment may further include a container loading assist device (100) that transmits the load of a container (C) loaded upwardly to the hull (10), at least a portion of which is mounted on the hull (10).

[0335] The container loading assist device (100) can be installed at the entrance of at least one cargo hold (17) among a plurality of cargo holds (17) to which the first composite bridge (20b) is applied.

[0336] A hatch cover (HC) may be installed at the entrance of the cargo hold (17) to which the lashing bridge (60) is applied.

[0337] In this embodiment, it was described that the container loading assist device (100) is installed only at the entrance of the cargo hold (17) where the first composite bridge (20b) is provided, but it is obvious that the container loading assist device (100) can also be installed at the entrance of the cargo hold (17) where the lashing bridge (60) is applied, by omitting the hatch cover (HC).

[0338] The first composite bridge (20b) may include a plurality of vertical members (21) arranged at regular intervals on an upper deck (11) that partitions the cargo holds (17) in the same or similar manner as the top bridge (20) of the first embodiment, and a plurality of horizontal members (22) installed at regular intervals on the plurality of vertical members (21).

[0339] However, in the case of the top bridge (20) of the first embodiment, the plurality of vertical members (21) are installed with a width equal to the width of the upper deck (11) that partitions the cargo hold (17), but in the case of the first composite bridge (20b) of the present embodiment, they may be installed with a width narrower than the width of the upper deck (11).

[0340] A plurality of vertical members (21) may include outer vertical members (21a) arranged in pairs on the left and right upper decks (11) of the hull (10), and intermediate vertical members (21b) arranged in multiple positions in the left and right directions of the hull (10) between the outer vertical members (21a).

[0341] A plurality of intermediate vertical members (21b) may be provided with an inverted U-shaped passageway (not shown in drawing) that penetrates in the left and right directions so that a worker can move through the horizontal member (22) for maintenance and monitoring of the loaded container (C).

[0342] The first composite bridge (20b) applied to the seventh embodiment can be installed on the upper deck (11) on the front and rear sides of one of the cargo holds (17), as shown in FIG. 29.

[0343] At this time, in the first composite bridge (20b) installed on the front and rear upper deck (11) of the cargo hold (17), the inner surfaces facing each other can be arranged so that the upper cell guide (32) is integrally connected with the lower cell guide (31) installed inside the cargo hold (17) to form a guide path for the loaded container (C).

[0344] In the first composite bridge (20b) installed on the front and rear upper deck (11) of the cargo hold (17), the outer surface facing the adjacent lashing bridge (60) may be structured such that the upper cell guide (32) is omitted, and the outer surface with the omitted upper cell guide (32) is positioned on the inner side of the upper deck (11) so as to be offset from the lower cell guide (31). That is, the first composite bridge (20b) may be installed with a width narrower than the width of the front and rear upper deck (11) of the entrance of the cargo hold (17).

[0345] Additionally, the first composite bridge (20b) applied to the seventh embodiment, although not illustrated, can be installed continuously or discontinuously as a set of two first composite bridges (20b) each installed on the front upper deck (11) and the rear upper deck (11) forming the entrance of the cargo hold (17). When two first composite bridges (20b) forming a set are installed discontinuously, other bridges such as the aforementioned lashing bridge (60), the top bridge (20) of the first embodiment, or the first deck bridge (20a) of the fifth embodiment may be installed on the upper deck (11) between them.

[0346] As mentioned above, the first composite bridge (20b) of the seventh embodiment is configured to be identical or similar to the structure in which an upper cell guide (32) is installed, which is integrally formed by connecting one side to the lower cell guide (31) of the top bridge (20) of the first embodiment, and the other side is configured to be identical or similar to the structure in which the upper cell guide (32) is omitted from the top bridge (20) of the first embodiment or the structure of one side of the lashing bridge (60). Of course, a second composite bridge (not shown) of another embodiment of such a first composite bridge (20b) can also be applied to a container carrier (1).

[0347] Unlike the first composite bridge (20b) shown in FIG. 29, the second composite bridge may be configured such that the upper cell guide (32) installed on one side is not connected to the lower cell guide (31) and formed as a single unit, but is instead provided on the inner side of the upper deck (11) so as to be offset from the lower cell guide (31).

[0348] That is, the second composite bridge may be provided on the upper deck (11) between the plurality of cargo holds (17). On one side of the second composite bridge, an upper cell guide (32) may be formed on the side adjacent to the first cargo hold (17) among the plurality of cargo holds (17) but not integrally connected to the lower cell guide (31), and on the other side of the second composite bridge (20b), the upper cell guide (32) may be omitted on the side adjacent to the second cargo hold (17) which is adjacent to the first cargo hold (17). The side of the second composite bridge where the upper cell guide (32) is omitted may be located on the inner side of the upper deck (11) offset from the lower cell guide (31).

[0349] With reference to FIG. 30 (a) to (c), the arrangement relationship of the bridges installed on the container carrier (1) according to the seventh embodiment of the present invention will be explained.

[0350] FIG. 30 (a) discloses a first loading area in which a bridge is installed to guide and support a container (C) provided above the upper deck (11) by an upper cell guide (32) that is continuously connected to a lower cell guide (31).

[0351] In the first loading area, the bridges installed on the front upper deck (11) and the rear upper deck (11), respectively, forming the entrance of the cargo hold (17), may be integrally formed with a first guide part (GP1) facing the cargo hold (17) and connected to a lower cell guide (31). In this case, the first guide part (GP1) may be an upper cell guide (32) that is integrally formed by connecting to the lower cell guide (31) and guides and fixes a container (C1) of the first size. At this time, the aforementioned container loading assist device (100) may be installed at the entrance of the cargo hold (17).

[0352] The bridge of the first loading area provided at the front and rear of the cargo hold (17) illustrated in FIG. 30 (a) may have an upper cell guide (32) that is continuously connected to a lower cell guide (31) on at least one side.

[0353] The bridge of the first loading area may be the first composite bridge (20b) of the present embodiment, in which the inner surface facing the cargo hold (17) is structured such that the upper cell guide (32) is integrally connected to the lower cell guide (31) to form a continuous guide path, and the outer surface is structured such that the upper cell guide (32) is omitted, the lower cell guide (31) is not integrally connected, and the bridge is offset forward or backward relative to the hull (10) from the upper deck (11).

[0354] Additionally, the bridge of the first loading area may be the top bridge (20) of the first embodiment described above, in which both upper cell guides (32) provided on both sides are integrally connected with the lower cell guide (31) to form a continuous guide path.

[0355] FIG. 30 (b) discloses a second loading area in which a bridge is installed to guide and support a container (C) provided above the upper deck (11) by an upper cell guide (32) that is offset from the lower cell guide (31).

[0356] In the second loading area, the bridges installed on the front upper deck (11) and the rear upper deck (11), respectively, forming the entrance of the cargo hold (17), may be configured such that the second guide portion (GP2), facing the cargo hold (17) in between, is offset from the lower cell guide (31). In this case, the second guide portion (GP2) is configured to be offset from the lower cell guide (31) and may be an upper cell guide (32) that guides and fixes a container (C2) of the second size. At this time, the aforementioned third container loading assist device (100c) or hatch cover (HC) may be installed at the entrance of the cargo hold (17). Although the drawing shows the third container loading assist device (100c) or hatch cover (HC) being installed at the entrance of the cargo hold (17), it is obvious that the aforementioned container loading assist device (100) may also be installed.

[0357] The bridge of the second loading area provided at the front and rear of the cargo hold (17) illustrated in Fig. 30 (b) may have an upper cell guide (32) that is offset from the lower cell guide (31) on at least one side.

[0358] The bridge of the second loading area may be a second composite bridge (not shown) of the present embodiment, in which the inner surface facing the cargo hold (17) is structured such that the upper cell guide (32) is not integrally connected with the lower cell guide (31) and is offset forward or backward relative to the hull (10) on the upper deck (11), and the outer surface is structured such that the upper cell guide (32) is omitted and is not integrally connected with the lower cell guide (31) and is offset forward or backward relative to the hull (10) on the upper deck (11).

[0359] Additionally, the bridge of the second loading area may be the first deck bridge (20a) of the aforementioned fifth embodiment, in which the inner surface facing the cargo hold (17) is structured such that the upper cell guide (32) is not integrally connected with the lower cell guide (31) and is offset forward and backward relative to the hull (10) on the upper deck (11), and the outer surface is structured such that the upper cell guide (32) is integrally connected with the lower cell guide (31) to form a continuous guide path.

[0360] Additionally, the bridge of the second loading area may be a second deck bridge (not shown) of the fifth embodiment, in which the inner surface facing the cargo hold (17) is configured such that the upper cell guide (32) is not integrally connected with the lower cell guide (31) and is offset forward or backward relative to the hull (10) on the upper deck (11), and the outer surface is configured such that the upper cell guide (32) is not integrally connected with the lower cell guide (31) and is offset forward or backward relative to the hull (10) on the upper deck (11).

[0361] That is, among the two bridges of the second loading area provided at the front and rear of the cargo hold (17) shown in Fig. 30 (b), the bridge provided at the front of the cargo hold (17) is any one of the second composite bridge of the present embodiment, the first deck bridge (20a) of the fifth embodiment, and the second deck bridge of the fifth embodiment, and the bridge provided at the rear of the cargo hold (17) is any one of the second composite bridge of the present embodiment, the first deck bridge (20a) of the fifth embodiment, and the second deck bridge of the fifth embodiment, so the two bridges of the second loading area provided at the front and rear of the cargo hold (17) may be of the same type of bridge or different bridges.

[0362] Figure 30 (c) discloses a third loading area in which at least one side has a structure in which the upper cell guide (32) is omitted and is not integrally connected with the lower cell guide (31) and is arranged to be offset forward and backward relative to the hull (10) on the upper deck (11), and a bridge is installed to secure the container (C) by a lashing member (23) on at least one side in which the upper cell guide (32) is omitted.

[0363] In the third loading area, the bridges installed on the front upper deck (11) and the rear upper deck (11), respectively, which form the entrance of the cargo hold (17), may be configured such that the lashing portion (LP) facing the cargo hold (17) is offset from the lower cell guide (31). In this case, the upper cell guide (32) is omitted, and the lashing portion (LP) has a structure that is offset forward and backward relative to the hull (10) on the upper deck (11) without being integrally connected to the lower cell guide (31), and may be one side of the bridge capable of securing a container (C1) of the first standard size by means of a lashing member (23). At this time, a hatch cover (HC) may be installed at the entrance of the cargo hold (17). Although the drawing shows a hatch cover (HC) installed at the entrance of the cargo hold (17), it is obvious that the aforementioned container loading assist device (100) or the third container loading assist device (100c) may also be installed.

[0364] The bridge of the third loading area provided at the front and rear of the cargo hold (17) illustrated in Fig. 30 (c) may have a structure in which the upper cell guide (32) is omitted on at least one side and is not integrally connected with the lower cell guide (31), and is offset from the upper deck (11) relative to the hull (10) in the front and rear directions.

[0365] The bridge of the third loading area may be the first composite bridge (20b) of the present embodiment, in which the inner side facing the cargo hold (17) is formed such that the upper cell guide (32) is omitted and is not integrally connected with the lower cell guide (31), and is offset forward or backward relative to the hull (10) from the upper deck (11), and the outer side is formed such that the upper cell guide (32) is integrally connected with the lower cell guide (31) to form a continuous guide path. In describing the first composite bridge (20b), it is described here that among the two bridges facing the cargo hold (17), one bridge is the first composite bridge (20b) and the other bridge is the lashing bridge (60), and in the seventh embodiment (Fig. 29), the two bridges facing the cargo hold (17) are described as the first composite bridge (20b). Accordingly, it should be noted that the description of the inner side of the bridge facing each other with the cargo hold (17) in between and the outer side opposite the inner side are expressed differently.

[0366] Additionally, the bridge of the third loading area may be a lashing bridge (60) in which the inner side facing the cargo hold (17) is formed such that the upper cell guide (32) is omitted and is not integrally connected with the lower cell guide (31), and is offset forward or backward relative to the hull (10) from the upper deck (11), and the outer side is formed such that the upper cell guide (32) is omitted and is not integrally connected with the lower cell guide (31), and is offset forward or backward relative to the hull (10) from the upper deck (11).

[0367] That is, among the two bridges of the third loading area provided at the front and rear of the cargo hold (17) shown in Fig. 30 (c), the bridge provided at the front of the cargo hold (17) is either the first composite bridge (20b) or the lashing bridge (60) of the present embodiment, and the bridge provided at the rear of the cargo hold (17) is either the first composite bridge (20b) or the lashing bridge (60) of the present embodiment, so the two bridges of the third loading area provided at the front and rear of the cargo hold (17) may be of the same type of bridge or different bridges.

[0368] As described with reference to (a) to (c) of FIG. 30 above, the container carrier (1) of the present embodiment is installed in a first loading area in which a bridge is installed on the upper deck (11) on the front and rear sides forming the entrance of the cargo hold (17), and the inner surface facing the cargo hold (17) is structured such that the upper cell guide (32) is integrally connected with the lower cell guide (31) to form a continuous guide path; and the second loading area in which a bridge is installed on the upper deck (11) on the front and rear sides forming the entrance of the cargo hold (17), and the inner surface facing the cargo hold (17) is structured such that the upper cell guide (32) is omitted and is not integrally connected with the lower cell guide (31), and is offset forward and backward relative to the hull (10) from the upper deck (11), and the bridge is installed on the upper deck (11) on the front and rear sides forming the entrance of the cargo hold (17). The third loading area may include a bridge installed on the inner side facing the cargo hold (17), in which the upper cell guide (32) is omitted and the lower cell guide (31) is not integrally connected, and the bridge is structured to be offset forward or backward relative to the hull (10) from the upper deck (11).

[0369] The container carrier (1) according to the 7th embodiment may be arranged such that at least two of the first to third loading areas are mixed in the forward and backward directions of the upper deck (11).

[0371] FIGS. 31 to 35 are drawings for explaining a container carrier according to the eighth embodiment of the present invention. In FIG. 35, the right-hand drawing is a drawing with a part of the structure of the top bridge (20) removed to show a drain (721) formed in the auxiliary coaming member (72).

[0372] A container carrier (1) according to the eighth embodiment comprises, as described above, a hull (10) comprising a side plate (12) forming a double hull structure with a side outer plate (12a) and a side inner plate (12b), a bottom plate (13) forming a double bottom structure with a bottom outer plate (13a) and a bottom inner plate (13b), and an upper deck (11); a cargo hold (17) partitioned by a transverse bulkhead (16) inside the hull (10); a lower cell guide (31) installed at regular intervals on the transverse bulkhead (16); a top bridge (20) provided on the upper deck (11) and having an upper cell guide (32) that forms a guide path for a container (C); a container loading assist device (100) applied to the cargo hold (17) to allow a container (C) to be loaded upward; and on the upper deck (11) on the left and right sides of the entrance of the cargo hold (17). It may include an auxiliary coaming member (72) that is provided and protrudes to face the container loading assist device (100).

[0373] The upper cell guide (32) can be integrally connected with the lower cell guide (31) to form a guide path for a continuous container (C).

[0374] The container loading assist device (100) is installed such that its front and rear ends are supported on the upper deck (11) on the front and rear sides of the entrance of the cargo hold (17), and its two ends are not supported on the upper deck (11) on the left and right sides of the entrance of the cargo hold (17), and is mounted on the hull (10) to transfer the load of the container (C) loaded upward to the hull (10).

[0375] Additionally, the container carrier (1) according to the eighth embodiment may further include a coaming member (71) that is provided on the left and right sides of the entrance of the cargo hold (17) and protrudes upward from the upper deck (11).

[0376] At this time, the auxiliary coaming member (72) is provided above the coaming member (71), and at least a portion of it may be placed above the cargo hold (17), and may protrude to face the container loading auxiliary device (100) which is placed at a position spaced apart from the left and right sides of the entrance of the cargo hold (17), thereby suppressing foreign substances flowing into the left and right sides of the cargo hold (17).

[0377] These auxiliary coaming members (72) can be continuously connected along the longitudinal direction of the hull (10) and may include a closed portion (not shown in the drawing) provided at the part corresponding to the entrance of the cargo hold (17) and an open portion (not shown in the drawing) provided at the part corresponding to the top bridge (20).

[0378] The open portion of the auxiliary coaming member (72) may have a drain (721) that guides foreign matter entering the top bridge (20) to be discharged to the outside of the hull (10) along the left and right directions, as shown in FIG. 35.

[0379] The closed portion of the auxiliary coaming member (72) may be provided with an openable exhaust port (not shown) for ventilation inside the cargo hold (17). The exhaust port can discharge heat generated when reefer containers, etc. are loaded to the outside.

[0380] Additionally, the container carrier (1) according to the eighth embodiment may further include a bracket (80) provided at the corner of the entrance of the cargo hold (17), as shown in FIG. 33.

[0381] The container loading assist device (100) is positioned at a distance from the left and right sides of the entrance of the cargo hold (17) to avoid interference with the bracket (80), and as a result, a first gap (G1) is inevitably created.
