Description

Technical Field

[0001] This invention relates to a container stacking assistance device, a container carrier having the container stacking assistance device, and a method for loading and unloading containers. Background Technology

[0002] As container carriers gradually increase their loading capacity, ensuring the stability of transported containers during operation is becoming an important factor that has attracted attention.

[0003] Such container carriers use a structure called a compartment guide to load containers onto cargo holds that are positioned forward and backward from inside the hull. The container carrier attaches hatch covers to the hatch flanges, which are located at the cargo hold entrances on the upper deck of the hull. The containers are then loaded onto the hatch covers in multiple layers. Various accessories are used to secure the containers loaded onto the hatch covers to a securing platform located above the space between the cargo holds to prevent them from falling.

[0004] Hatch covers not only support the load of containers loaded on the upper deck and prevent foreign objects (seawater, rainwater, etc.) from flowing into the cargo hold, but also help to strengthen the longitudinal strength of the container carrier.

[0005] However, hatch covers are not only inconvenient to manufacture, transport, and install due to their high weight, but also require additional structures at the cargo hold entrance for installation, thus occupying a large amount of space between adjacent cargo holds, and the container cannot be loaded with as much space as that space.

[0006] Recently, a small container vehicle with an open-top concept without hatch covers has been studied to address the issues of hatch cover production / transportation / installation when transporting more containers.

[0007] When the open-top concept is applied to small container ships, the number of containers continuously loaded from the bottom of the hold to the upper deck must be limited to a certain number (e.g., 12 layers) or less due to the problem of damage to the lower containers during loading caused by the weight of the loaded containers, as well as the pitch and stability issues of the ship. There is also the problem that the side panels must be excessively increased compared to container ships of the same size, and the strength of the hull must be strengthened to prevent large amounts of seawater from flowing onto the ship's deck during ship operations in rough seas.

[0008] In large container ships, to prevent containers loaded on top of hatch covers from falling off, various accessories are used to secure / remove containers from the hatch covers on a rigging platform during loading and unloading. Most of this loading and unloading is done manually, requiring excessive work time and safety management, which increases the operating cost of the container ship. Furthermore, when severe weather causes excessive hull movement during container ship operation, imperfections in the hatch covers and rigging system—such as hatch covers moving under load, damage to deck or hatch cover fasteners, damage to rigging platform accessories, or relative displacement between the hatch covers and the hull—can lead to the continuous collapse of the rigging system, ultimately resulting in damaged or lost containers at sea. Summary of the Invention

[0009] The problem the invention aims to solve

[0010] The present invention addresses the problems of the aforementioned related technologies. The objective of the present invention is to provide a container stacking assistance device, a container carrier equipped with the container stacking assistance device, and a method for loading and unloading containers. This container stacking assistance device increases the loading capacity of large container carriers without hatch covers by increasing the number (layers) of containers continuously loaded from the bottom of the cargo hold to the upper part of the upper deck. Furthermore, the container stacking assistance device eliminates the need for assembly operations between the loaded containers and the tethering platform to prevent the loaded containers from tipping over.

[0055] The objects, specific advantages, and novel features of the invention will become clearer from the following detailed description and the preferred embodiments illustrated in conjunction with the accompanying drawings. When assigning reference numerals to components in the various drawings herein, it should be noted that even when the same component is shown in different drawings, the same component will, as far as possible, have only the same numbering. Furthermore, in describing the invention, detailed descriptions of relevant known technologies will be omitted where it is determined that such detailed descriptions may unnecessarily obscure the subject matter of the invention.

[0056] The preferred embodiments of the present invention will then be described in detail with reference to the accompanying drawings.

[0058] like Figures 1 to 18 As shown, the container carrier 1 according to an embodiment of the present invention can transport the container C from the place of origin to the destination by loading multiple layers of container C inside and outside the hull 10. As a new container carrier without hatch cover concept, it can be equipped with container stacking assistance device 100 or container stacking assistance device 100a for loading and supporting the container C.

[0059] In this embodiment, the container carrier 1 may be a large container ship carrying 13 or more layers of large containers C, including those extending from the bottom of the cargo hold 17 to the upper deck 11, but is not limited to this. Additionally, the containers C may include 20-foot containers (hereinafter referred to as "small containers") or 40-foot containers (hereinafter referred to as "large containers") primarily loaded on the container carrier 1. However, according to ISO standards, in addition to the aforementioned 20-foot or 40-foot containers as transport containers C, not only are containers C of various sizes used on ships, but there are also containers C of various specifications; therefore, the small containers C or large containers C described below are not limited to 20-foot or 40-foot containers.

[0060] In the above text, the container stacking assist devices 100 and 100a can be as follows: Figures 3 to 7 and Figure 17 The open container stacking assist device 100 shown can also be as follows: Figures 8 to 12 and Figure 18 The enclosed container stacking assistance device 100a is shown. Since the open container stacking assistance device 100 and the enclosed container stacking assistance device 100a are somewhat similar in construction and function, the following description will primarily focus on the open container stacking assistance device 100, while different configurations and functions of the enclosed container stacking assistance device 100a will be discussed with reference to... Figures 8 to 12 and Figure 18describe.

[0061] The hull 10 forms the exterior of the container carrier 1. The hull 10 is surrounded by the upper deck 11, side plates 12 and bottom plate 13.

[0062] The hull 10 can be formed by a double hull structure and a double bottom structure. In the double hull structure, the side plate 12 is composed of an outer side plate 12a and an inner side plate 12b. In the double bottom structure, the bottom plate 13 is composed of an outer bottom plate 13a and an inner bottom plate 13b.

[0063] Container C can be loaded inside the hull 10. For this purpose, a plurality of cargo holds 17 are provided inside the hull 10, which are separated in the fore-and-aft direction by transverse bulkheads 16. Inside the cargo holds 17, lower compartment guides 31 are installed at fixed intervals on the sides of the transverse bulkheads 16 to guide the loading of containers C in the cargo holds 17.

[0064] In this embodiment, cargo hold 17 has an open entrance structure, and no existing hatch cover is installed at the entrance. However, the container stacking assistance device 100, which will be described later, can be configured to be installed at the entrance of cargo hold 17 or at any location within cargo hold 17. In other words, the entrance of cargo hold 17 can be made of a simple structure so that the container stacking assistance device 100 can be installed. When the container stacking assistance device 100 is installed inside cargo hold 17, a recess (not shown) can be formed in the upper deck forming the entrance of cargo hold 17 so that the container stacking assistance device 100 can pass through the entrance of cargo hold 17.

[0065] Additionally, when the container stacking assistance device 100 of this embodiment is applied to a container carrier 1 having an existing tethering platform or a container carrier 1 having a hatch flange at the entrance of the cargo hold 17, it can be installed on the hatch flange on the upper deck 11 at the entrance of the cargo hold 17.

[0066] An engine room R may be located inside the hull 10 near the stern 15. A propulsion engine (not shown) is housed in the engine room R and is mechanically or electrically connected to a propeller to achieve propulsion by consuming liquefied gas as fuel.

[0067] Cabin A is located on the upper deck 11 of the hull 10. Cabin A is the living space for the crew and can be divided into several levels along the vertical direction, with the bridge for controlling navigation located on the uppermost level.

[0068] On the upper deck 11 of the hull 10, at the rear of the compartment A, is an engine casing I. The engine casing I has a funnel for discharging exhaust gases generated by the propulsion engine to the outside, and can be configured to house an emergency generator or fire extinguishing equipment.

[0069] In the upper deck 11 of the hull 10, container C can be loaded in the portion other than the hold A and engine casing I. For loading container C, top platforms 20 are spaced apart from each other and arranged on the upper deck 11 in the fore-and-aft direction.

[0070] The top platform 20 can be installed between the cargo holds 17 and extend to the port and starboard edges of the upper deck 11, and can be set at fixed intervals from the bow 14 to the stern 15.

[0071] On both sides of the top platform 20, upper compartment guides 32 can be installed at fixed intervals. In other words, the top platform 20 of this embodiment is not a tethering platform using an existing tethering system, but a compartment guiding system using upper compartment guides 32.

[0072] Each upper compartment guide 32 extends from the upper end of the top platform 20 to the upper deck 11 and can be integrally formed by connecting to each of the lower compartment guides 31 installed inside the cargo hold 17.

[0073] The upper compartment guide 32 guides the raising and lowering of small or large containers C transported by the crane CR. The upper compartment guide 32, mounted on the top platform 20, and the lower compartment guide 31, mounted on the transverse bulkhead 16, are respectively connected to allow for continuous loading and unloading of containers C without additional work such as hatch cover installation or rigging. The upper compartment guide 32 can support the lateral load of the small or large containers C generated by the movement of the hull 10.

[0074] In the top platform 20 of this embodiment, by installing upper compartment guides 32 on both sides, the upper compartment guides 32 can support and fix the container C, and the existing tethering system (such as fastening devices for tethering rods and tethering bars) can be omitted. This prevents the container C from falling off the front and rear of the container C, which is usually loaded in 1 to 4 layers. It can ensure access and working space for control units and other equipment set up in the refrigerated container C for maintenance and monitoring. During the operation of the container carrier 1, by directly supporting the container C on the upper deck 11, the problem of damage or loss of the loaded container C can be solved.

[0075] In particular, by eliminating the flaws in the hatch covers and tethering systems that are problems with traditional large container carriers, such as hatch covers moving due to load in cases of excessive hull movement during navigation due to severe weather, damage to the fastening devices of the deck or hatch covers, breakage of tethering platform components, or relative displacement of the hatch covers to the hull, the problem of continuous collapse of the tethering system that ultimately leads to damage to or loss of the loaded container C at sea can be solved.

[0076] In the case of existing tethered platforms, due to the application of the tethering system, sufficient width is required for tethering operations according to operator environment regulations. However, in the top platform 20 of this embodiment, by omitting the tethering system and applying the compartment guidance system, the width can be minimized and the complex structure of installing an existing tethered platform can be simplified. Since the width of the top platform 20 can be minimized, the width of the upper deck 11 between cargo holds 17 can be minimized compared to existing container carriers that install existing tethered platforms, and compared to container carriers 1 of the same specifications, design flexibility can be ensured (optimization is possible due to the reduction of hull length and other tethering systems), or the transport capacity of container C can be increased.

[0077] The top platform 20 can be composed of a combination of a plurality of vertical components 21 and a plurality of horizontal components 22.

[0078] Among the plurality of vertical components 21, two outer vertical components 21a arranged on the upper deck 11 on each of the port and starboard sides of the hull 10 can be arranged at intervals corresponding to the width of the small container C or the large container C.

[0079] Among the plurality of vertical components 21, the plurality of intermediate vertical components 21b arranged between the outer vertical components 21a can be arranged at intervals corresponding to twice the width of the small container C or the large container C.

[0080] Here, each of the upper compartment guides 32 can be arranged between each of the outer vertical assembly 21a and the plurality of intermediate vertical assemblies 21b, and is arranged between the plurality of intermediate vertical assemblies 21b.

[0081] Since the top platform 20 is combined with the upper compartment guide 32 that supports the lateral load of the container C generated by the movement of the hull 10, it is preferably configured to bear the lateral load.

[0082] Accordingly, Figure 27 As shown in (a) and (b), a structural analysis was performed on the inclined or vertical and horizontal components that constitute the top platform.

[0083] Figure 27 (a) is the top platform 20 of this embodiment, which is composed of a combination of a plurality of vertical components 21 and a plurality of horizontal components 22. Figure 27 (b) is a comparative example of a top platform 20-1 consisting of a combination of multiple tilting components 23.

[0084] As a result of the structural analysis, the load-bearing height in the inclined or vertical and horizontal directions was analyzed, and another embodiment of the top platform 20, top platform 20a and another embodiment of the top platform 20, top platform 20b, were obtained. Top platform 20a, as... Figure 28As shown, the top platform 20b is as follows Figure 29 As shown.

[0085] exist Figure 28 In another embodiment of the top platform 20a shown, a plurality of tilting components 23 are further installed to reduce the load applied to the plurality of vertical components 21 and the plurality of horizontal components 22 constituting the top platform 20.

[0086] The aforementioned plurality of tilting components 23 can be installed at an upward inclination from the lower end of each of the two outer vertical components 21a arranged on the upper deck 11 on the left and right sides of the hull 10 and the lower end of at least one of the intermediate vertical components 21b in the direction from the middle of the hull 10.

[0087] In addition, Figure 29 In another embodiment of the top platform 20b shown, a plurality of plate assemblies 24 are further installed to reduce the load on the plurality of vertical assemblies 21 and the plurality of horizontal assemblies 22 constituting the top platform 20.

[0088] The aforementioned plurality of plate assemblies 24 can be respectively installed in the plurality of intermediate vertical assemblies 21b, between an intermediate vertical assembly 21b adjacent to each outer vertical assembly 21a, and between two intermediate vertical assemblies 21b installed in the plurality of intermediate vertical assemblies 21b and arranged in the middle part of the hull 10.

[0089] Since the upper cabin guide 32 is installed at the top, or customized to be lower or higher than the top according to the needs of the ship owner, the top platform 20, top platform 20a and top platform 20b of the present invention can fundamentally prevent the loss of the container C due to overturning. According to the needs of the ship owner, the number of layers of the upper deck 11 can be customized and manufactured into a cabin block that integrates the upper and lower structures of the hull, so as to minimize weight and increase productivity.

[0090] Furthermore, in addition to the top platforms 20, 20a, and 20b, in order to apply the existing tethering system at the uppermost point in addition to the aforementioned compartment guidance system, at least one of the tethering eye, tethering ring, tethering plate, plug, and cone, which are the fixing devices of the tethering system, is additionally arranged to further improve the safety of the loaded container C.

[0091] According to an embodiment of the present invention, the container carrier 1 may further include hull extension members 50 protruding from the left and right sides of the hull 10, such as... Figure 14 As shown. The hull extension component 50 may consist of an extension deck 11a and a suspended outer plating 12a1.

[0092] The extension deck 11a can extend outward from the left and right edges of the upper deck 11, and is longer than the length corresponding to the width of the container C.

[0093] The overhanging outer plating 12a1 extends at a certain angle from the waterline DL to the edge of the extension deck 11a. The overhanging outer plating 12a1 reduces the likelihood of wave intrusion by giving the outer plating 12a a certain outward slope. Even when container ships 1 with a capacity of 6500 TEU or higher are loaded with containers C in eight (sometimes nine) decks within cargo hold 17, the actual likelihood of wave intrusion is very small; however, even taking this into account, the risk of wave intrusion can be reliably controlled by applying the overhanging outer plating 12a1.

[0094] The surrounding structure, which is modified by further including a hull extension component 50 in the container carrier 1, is described below.

[0095] First, in the side plate 12, which is composed of inner side plate 12b and outer side plate 12a, the outer side plate 12a may be composed of a vertical outer plate 12a2 and a hanging outer plate 12a1. The vertical outer plate 12a2 extends from the waterline DL to the bottom plate 13, and the hanging outer plate 12a1 extends from the waterline DL to the edge of the extension deck 11a.

[0096] The top platform 20 can be installed extending from the port and starboard edges of the upper deck 11 to the port and starboard edges of the extension deck 11a. Here, on the extension deck 11a between the top platforms 20 facing each other in the fore-and-aft direction, small or large containers C can be additionally loaded, and on the extension decks 11a on the port and starboard sides of the hull 10 between the top platforms 20 facing each other in the fore-and-aft direction, reinforced bulkheads 60, which will be described later, can be discontinuously installed along the port and starboard edges of the hull 10.

[0097] Additionally, the top platform 20 extends from the port and starboard edges of the upper deck 11 to the port and starboard edges of the extension deck 11a, and can be extended and installed to ensure space for the installation of the reinforced bulkhead 60, which will be described later. Here, the reinforced bulkhead 60, which will be described later, can be installed continuously along the edges of the extension deck 11a on the port and starboard sides of the hull 10.

[0098] Although the container carrier 1 according to the above embodiment of the present invention is described as having a top platform 20 with an applied compartment guidance system, it is not limited thereto. A tethered platform with a similar or identical tethering system can be installed in some sections of a row or on the left and right sides of a row. In other words, the container carrier 1 according to the embodiment of the present invention can have a hybrid platform that combines a top platform 20 and a tethered platform, in which the compartment guidance system of the present invention can be applied to the top platform 20 and existing tethering systems can be applied to the tethered platform.

[0099] According to an embodiment of the present invention, the container carrier 1 may further include reinforced bulkheads 60 installed on the left and right sides of the hull 10 to improve the bending moment caused by the arching or sagging of the hull 10.

[0100] The reinforced bulkhead 60 can be formed as a double hull structure similar to the side plate 12, and can be installed at the edges of the upper deck 11 on the left and right sides of the hull 10.

[0101] The width of the reinforced bulkhead 60 is less than the width of the side plate 12 forming the twin hull structure, and the height of the reinforced bulkhead 60 can be formed to be equal to or less than the height of the top platform 20.

[0102] The reinforced bulkhead 60 can be formed from various catamaran structures, such as partially open or closed types.

[0103] In reinforced bulkhead 60, based on the formula used to obtain the moment of inertia, I = Bh 3 / 12 (where I is the moment of inertia, B is the width, and h is the height), as h increases, the moment of inertia increases, and is formed to connect to the side plate 12, ultimately resulting in an increase in the height of the side plate 12, and can improve the bending moment caused by arching or sagging.

[0104] When the top platform 20 is installed to extend to the port and starboard edges of the upper deck 11, or when the extension deck 11a is further configured and the top platform 20 is installed to extend from the port and starboard edges of the upper deck 11 to the port and starboard edges of the extension deck 11a, a reinforced bulkhead 60 may be installed on the port and starboard edges of the hull 10 between the top platforms 20 facing each other in the fore-and-aft direction, and is arranged discontinuously along the port and starboard edges of the hull 10. The reinforced bulkhead 60 may be connected to the top platform 20.

[0105] When the extension deck 11a is further constructed and the top platform 20 extends from the port and starboard edges of the upper deck 11 to the port and starboard edges of the extension deck 11a, but is extended to ensure space for the installation of the reinforced bulkhead 60, the reinforced bulkhead 60 can be continuously installed along the edges of the extension deck 11a on the port and starboard sides of the hull 10. The reinforced bulkhead 60 can be attached to the top platform 20.

[0106] The container carrier 1 according to an embodiment of the present invention may further include a drain outlet 70, such as Figure 14 As shown. When the side plate 12 is a double hull structure consisting of an inner side plate 12b and an outer side plate 12a, the drainage outlet 70 can extend outward through the side plate 12 of the double hull structure on the freeboard deck 19, so that water can be discharged from the dock to the outside.

[0107] like Figure 15 As shown, the container carrier 1 according to an embodiment of the present invention may further include a support structure 80.

[0108] The support structure 80 is arranged on the bottom surface of the cargo hold 17 to support the container C upward and at intervals, and a flow channel is formed between the bottom surface of the cargo hold 17 and the lowest container C to allow foreign objects (such as seawater, rainwater, etc.) flowing into the cargo hold 17 to flow.

[0109] In the case where the bottom plate 13 has a double bottom structure consisting of an inner bottom plate 13b and an outer bottom plate 13a, the support structure 80 can be installed on the bottom surface of the inner bottom plate 13b at fixed intervals, so that the container C is not flooded by foreign objects such as seawater or rainwater seeping into the entrance of the cargo hold 17 while supporting the container C.

[0110] The support structure 80 can be installed at the bottom of the inner bottom plate 13b and at a position corresponding to the corner casting (not shown) of the container C, or it can be installed at the bottom of the inner bottom plate 13b and at a position corresponding to the middle part between the corner castings of adjacent loaded containers C.

[0111] The support structure 80 may have a height of 250mm to 350mm from the bottom of the inner bottom plate 13b.

[0112] In the container carrier 1 of the embodiments of the present invention, such as Figure 16 As shown, a drainage system 90 can be installed on the floor 13 to discharge water that seeps in through the inlet of cargo compartment 17 to the outside.

[0113] When the bottom plate 13 has a double bottom structure consisting of an inner bottom plate 13b and an outer bottom plate 13a, the drainage system 90 can be configured such that water entering through the drain holes 92 formed on the inner bottom plate 13b is collected in the box-shaped bilge wells 91 formed below the inner bottom plate 13b on the lower left and lower right sides of the transverse bulkhead 16, and the water collected in the bilge wells 91 is discharged into the bilge pump (not shown) of the engine room R through the drain pipe (not shown) of the pipe 93.

[0114] The container carrier 1 according to an embodiment of the present invention may be equipped with a container stacking assistance device 100.

[0115] A container stacking assist device 100 is installed in a container carrier 1 without a hatch cover and applied to at least one cargo compartment 17. It can be configured to load and support small or large containers C on its upper side and may include an upper frame 111, a lower frame 112, a support member 113, a protruding assembly 120, a reinforcing frame 130, a first assembly assembly 141, and a second assembly assembly 142. In the container stacking assist device 100, the upper frame 111, lower frame 112, and support member 113 can be combined to form a main body 110, the overall shape of which is a rectangular box.

[0116] The upper frame 111 can be configured as a rectangle, with its width corresponding to the width of the small container C or the large container C, and its length corresponding to the length of the large container C.

[0117] The upper frame 111 may consist of a pair of first long axis frames 111a and a pair of first short axis frames 111b. The first long axis frames 111a are arranged such that their width corresponds to the width of the small container C or the large container C, and their length corresponds to the length of the large container C. The pair of first short axis frames 111b connects each end of the pair of first long axis frames 111a, and the width of the pair of first short axis frames 111b corresponds to the width of the small container C or the large container C.

[0118] The lower frame 112 can be configured in a rectangular shape, with its width corresponding to the width of the small container C or the large container C, and its length corresponding to the length of the large container C.

[0119] The lower frame 112 may consist of a pair of second long axis frames 112a and a pair of second short axis frames 112b. The second long axis frames 112a are arranged such that their width corresponds to the width of the small container C or the large container C, and their length corresponds to the length of the large container C. The pair of second short axis frames 112b connects each end of the pair of second long axis frames 112a, and the width of the pair of second short axis frames 112b corresponds to the width of the small container C or the large container C.

[0120] In the above, each of the pair of second long axis frames 112a can be configured such that both ends are connected to the lower end of the support 113 described later, and has a downward slope near the inside and is bent to remain horizontal with each of the first long axis frames 111a in the middle portion.

[0121] The support member 113 can be arranged along the height direction of the upper frame 111 and the lower frame 112, and can be configured to connect each corner of the upper frame 111 and each corner of the lower frame 112.

[0122] The protruding component 120 can be configured to project outwards from the upper frame 111 and lower frame 112 or support member 113, allowing it to be installed at any location within the cargo hold 17. The protruding component 120 can also be configured to project longitudinally outwards from the lower end of each support member 113 for installation at the entrance of the cargo hold 17 or at any location within the cargo hold 17.

[0123] When the protruding component 120 is installed on the upper deck 11 at the entrance of the cargo hold 17, the load of the small container C or the large container C transmitted through the support 113 can be transferred to the upper deck 11.

[0124] When the protruding component 120 is installed at any location within the cargo hold 17 using the position adjustment assembly 40 described later, a recess is formed in the upper deck 11 of the cargo hold 17 entrance, through which the protruding component 120 enters the portion where it is installed. Accordingly, the protruding component 120 is installed on the position adjustment assembly 40 described later through the recess formed in the upper deck 11. The position adjustment assembly 40 is installed at any location within the transverse bulkhead 16 of the cargo hold 17, and the protruding component 120 can transfer the load of the small or large container C transmitted via the support 113 to the transverse bulkhead 16.

[0125] When the container stacking assistance device 100 of the present invention is applied to an existing container vehicle equipped with a tethering platform or an existing container vehicle having a hatch at the entrance of the cargo hold 17, the protruding component 120 may be installed on the upper hatch edge of the upper deck 11 at the entrance of the cargo hold 17.

[0126] The reinforcing frame 130 connects the middle part of the upper frame 111 in the length direction and the middle part of the lower frame 112 in the length direction, and can support the load of small or large containers C loaded on the upper surface of the container stacking assist device 100.

[0127] The reinforcing frame 130 may be composed of a first horizontal reinforcing rib 131, a second horizontal reinforcing rib 132, a first vertical reinforcing rib 133, and a second vertical reinforcing rib (not shown). The first horizontal reinforcing rib 131 connects the middle portion of each of the pair of first long axis frames 111a, the second horizontal reinforcing rib 132 connects the middle portion of each of the pair of second long axis frames 112a, the first vertical reinforcing rib 133 connects one end of the first horizontal reinforcing rib 131 and one end of the second horizontal reinforcing rib 132, and the second vertical reinforcing rib connects the other end of the first horizontal reinforcing rib 131 and the other end of the second horizontal reinforcing rib 132.

[0128] The container stacking assistance device 100 may further include a first plate 151, a second plate 152, and a reinforcing component 160.

[0129] The first plate 151 can be installed in a side frame formed by either of the pair of first long axis frames 111a, either of the pair of second long axis frames 112a, and the support member 113 connecting its two ends.

[0130] The second plate 152 can be installed in 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 the support member 113 connecting its two ends.

[0131] The reinforcing component 160 can be installed on at least one of the outer and inner sides of the first plate 151 and the second plate 152.

[0132] When the reinforcing assembly 160 is mounted on the outer surface of each of the first plate 151 and the second plate 152, the reinforcing assembly 160 may consist of an intermediate reinforcing assembly 161 connected to each of the pair of first long axis frames 111a and the pair of second long axis frames 112a, and a first reinforcing assembly 162 and a second reinforcing assembly 163 arranged between the support members 113 on both sides of the intermediate reinforcing assembly 161 and connected to each of the pair of first long axis frames 111a at the curved portion of the pair of second long axis frames 112a, facing each of the first vertical reinforcing rib 133 and the second vertical reinforcing rib, with the first plate 151 and the second plate 152 inserted therebetween.

[0133] In this embodiment, the pair of second long axis frames 112a are described as having a curved form, but they can be formed in a flat form. In other words, the container stacking assist device 100 of this embodiment can be manufactured in the form of a rectangular box.

[0134] The container stacking assistance device 100 of the present invention can ensure the rigidity to support the load of the container C loaded on its own body by including all or part of the reinforcing frame 130, the first plate 151 and the second plate 152 and the reinforcing component 160, unlike conventional similar technologies.

[0135] The first assembly component 141 is located at the upper part of each corner of the upper frame 111 and can be used for fixing when loading large or small containers C, or for lifting when transported by crane CR.

[0136] A pair of second assembly components 142 are positioned at the upper part of the middle section of the upper frame 111 and can be used to secure the small container C when it is loaded, or to be hoisted together with the first assembly component 141 when transported by crane CR.

[0137] In the above, the first assembly component 141 can be formed at the same height at each corner of the upper frame 111, and the second assembly component 142 can be set at the upper end of the middle portion of each of the pair of first long shaft frames 111a, and can be formed to be 5mm to 15mm higher than the height of the first assembly component 141, so that when two small containers C arranged along the length direction are loaded, even if they tilt inward due to buckling caused by the load, the two small containers C facing each other will not come into contact with each other.

[0138] The container stacking assistance device 100 of the present invention includes a first assembly component 141 and a second assembly component 142, which allows small containers C and large containers C to be mixed and firmly fixed on the upper surface, unlike conventional similar technologies.

[0139] The container stacking assistance device 100 may further include a coupling component 170 of the parallel body 110, such as Figure 19 As shown.

[0140] The coupling assembly 170 can connect two or more upper frames 111 and lower frames 112 arranged adjacent to each other. The coupling assembly 170 can consist of a first coupling assembly 171 mounted on each side of at least two upper frames 111 and a second coupling assembly 172 mounted on each side of at least two lower frames. The first coupling assembly 171 and the second coupling assembly 172 can be hinged gaskets.

[0141] The first coupling component 171 can be fixed to each of the pair of first long shaft frames 111a, and can be rotatably connected to the upper part of each of the first reinforcing component 162 and the second reinforcing component 163.

[0142] The second coupling component 172 can be fixed to each of the pair of second long shaft frames 112a, and can be rotatably connected to the lower part of each of the first reinforcing component 162 and the second reinforcing component 163.

[0143] In the above text, when the main body 110 is connected in parallel, the first coupling component 171 can connect to the upper part of the adjacent main body 110, and when the main body 110 is connected in parallel, the second coupling component 172 can connect to the lower part of the adjacent main body 110.

[0144] The first coupling component 171 and the second coupling component 172 can maintain a constant interval between the parallel-connected main bodies 110. In other words, when the container stacking assistance device 100 of this embodiment is connected in parallel via the first connector 171 and the second coupling component 172, a certain interval is formed between adjacent container stacking assistance devices 100, and this interval can have a spacing that allows the upper compartment guide 32 to be inserted.

[0145] When the container stacking assistance device 100 of this embodiment is connected in parallel using the first coupling component 171 and the second coupling component 172, the first plate 151 and the second plate 152 of each adjacent container stacking assistance device 100 become a closed structure. Although it may be difficult to fasten the first coupling component 171 and the second coupling component 172 through a certain interval gap, holes (not shown) can be formed in the first plate 151 and the second plate 152 corresponding to the positions of the first coupling component 171 and the second coupling component 172, or operating spaces can be separately provided in the upper frame 111 and the lower frame 112, or fastening can be achieved by methods such as using a separate tool.

[0146] When transported by crane, the container stacking assistance device 100 can be transported individually without parallel main bodies 110, or it can be transported with at least two main bodies 110 connected in parallel via a first coupling assembly 171 and a second coupling assembly 172.

[0147] In this embodiment, although it has been described that at least two or more container stacking assistance devices 100 are connected in parallel using the first coupling component 171 and the second coupling component 172, the invention is not limited thereto. The container stacking assistance devices 100 can be manufactured in a configuration where two or more are connected laterally, with a certain gap between the connected devices. This gap can be large enough to allow for the insertion of the upper compartment guide 32. In other words, the container stacking assistance devices 100 of the present invention can encompass both single and multiple types.

[0148] In this embodiment, when the container stacking assistance device 100 is of a single type, although the dimensions (width and length) of the upper frame 111 and the lower frame 112 have been described based on the small container C or the large container C, when the container stacking assistance device 100 is of multiple types, the width and length of the upper frame 111 and the lower frame 112 are 1 to n times the width and length of the small container C or the large container C (n is a natural number), and the upper frame 111 and the lower frame 112 simultaneously have a planar cross-section smaller than the entrance of the cargo hold 17.

[0149] In the above description, it is preferable to connect an odd number of container stacking aids 100 in parallel to align the center of gravity when transporting them by the crane CR. In other words, when transporting the container stacking aids 100 using a spreader SR attached to the crane CR, since the spreader SR is connected to the container stacking aid 100 located at the center of the parallel container stacking aids 100, it is necessary to connect an odd number of container stacking aids 100 to facilitate alignment of the center of gravity during transport. The number of parallel container stacking aids 100 can vary depending on the operating load of the crane CR.

[0150] The container stacking assistance device 100 may further include a stowage assembly 180 that is vertically connected to and / or supports the main body 110.

[0151] like Figure 20 and Figure 21 As shown, the stowage assembly 180 may have a structure capable of switching from a first state of stowage on a transport vehicle TR or stowage on land 2 to a second state of stowage on the container carrier 1.

[0152] The stacking assembly 180 may consist of stacking legs 181 mounted on the outer side of each side of the support 113 in the width direction and a third assembly assembly 182 disposed at the lower end of each stacking leg 181 and fastened to the first assembly assembly 141, wherein the first assembly assembly 141 is disposed on the upper body 110 when the body 110 is stacked in multiple layers.

[0153] When the main body 110 is stacked into multiple layers using the first assembly assembly 141 and the third assembly assembly 182, the stacking legs 181 can be configured such that the pair of second assembly assemblies 142 disposed on the lower main body 110 does not contact the lower frame 112 of the upper main body 110.

[0154] In other words, when the container stacking assist device 100 is vertically stacked, the stacking leg 181 is configured to be long enough that the bottom of the container stacking assist device 100 stacked on top and the top of the container stacking assist device 100 stacked on the bottom will not contact each other. This is because when the upper and lower container stacking assist devices 100 are in contact, they may be damaged due to contact friction when shaking occurs due to external environmental factors.

[0155] The stowage assembly 180 configured as described above has the functions of safely storing the container stacking assistance device 100 when manufactured or stowed on land 2, supporting and connecting each container stacking assistance device 100 that is vertically stowed when multiple container stacking assistance devices are transported from land 2 to transport vehicle TR, and supporting and connecting each container stacking assistance device even when multiple container stacking assistance devices 100 are stowed and stored in some compartments 18 of container carrier 1, as well as the function of being able to connect and / or support the container stacking assistance device 100.

[0156] When the container stacking assistance device 100 is raised and lowered between adjacent top platforms 20 by the crane CR, the container stacking assistance device 100 configured as described above can be guided by the upper compartment guide 32.

[0157] Additionally, during container unloading operations or before container loading operations, such as Figure 21As shown, the container stacking assistance device 100 can be stowed and stored between the outer vertical components 21a facing forward and backward on the upper deck 11 on the port or starboard side of the hull 10, and although not shown, it can be stowed and stored between the intermediate vertical components 21b facing forward and backward, and even when two or more container stacking assistance devices 100 are connected in parallel, it can be stowed and stored between two or more vertical components 21. In this way, by stowing and storing the container stacking assistance device 100 in the container carrier 1, a separate stowage location on land is not required, which improves the efficiency of loading and unloading the container C.

[0158] Additionally, when the container stacking assistance device 100 is connected in parallel via the first coupling assembly 171 and the second coupling assembly 172, a gap is formed between adjacent container stacking assistance devices 100, and when the crane CR rises and falls between adjacent top platforms 20, the upper compartment guide 32 can be inserted into the gap and guided.

[0159] As described above, the left and right sides of the main body 110 are sealed with the first plate 151 and the second plate 152, and the top, bottom, front and rear of the main body 110 are open, forming an open container stacking assistance device 100. The closed container stacking assistance device 100a will be described next.

[0160] like Figures 8 to 12 and Figure 18 As shown, compared to the open container stacking assistance device 100, the closed container stacking assistance device 100a may be similar to the open container stacking assistance device 100 in overall shape, function and configuration, but may differ in the further configuration of the waterproof component 153.

[0161] The enclosed container stacking assistance device 100a will then be described, and since its configuration, except for the waterproof component 153, is the same as or similar to that of the open container stacking assistance device 100, the same reference numerals will be used (…). Figures 8 to 12 and Figure 18 References not shown in the text Figures 3 to 7 and Figure 17 (as shown in the diagram), therefore, to avoid repetition, detailed descriptions of each identical component will be omitted here, and only the waterproof component 153, which is different from the open container stacking assistance device 100, and the parts that vary due to the waterproof component 153 will be described.

[0162] The waterproofing assembly 153 is installed on the upper deck 11 at the entrance of the cargo hold 17 with an enclosed container stacking assistance device 100a. When the container C is loaded on top of it, it can be configured to prevent water (seawater or rainwater) from entering the cargo hold 17, and may include a first waterproofing plate 153a, a second waterproofing plate 153b and a third waterproofing plate 153c.

[0163] The first waterproof panel 153a can be installed on the upper side frame, which consists of a pair of first long axis frames 111a and a pair of first short axis frames 111b constituting the upper frame 111, and the first waterproof panel 153a can prevent water from entering the interior of the cargo hold 17 through the upper part of the enclosed container stacking assistance device 100a.

[0164] The second waterproofing plate 153b can be installed on the front and rear side frames formed by the first short shaft frame 111b of the upper frame 111, the support member 113, and the protruding assembly 120, and can prevent water from entering the cargo hold 17 through the front and rear of the enclosed container stacking assist device 100a. The lower part of the second waterproofing plate 153b protrudes outward corresponding to the shape of the protruding assembly 120, thereby being located on the upper deck 11 at the entrance of the cargo hold 17.

[0165] The third waterproofing plate 153c can be installed at a specific height along the edge of each of the pair of first long axis frames 111a constituting the upper frame 111, and guide the water accumulated on the first waterproofing plate 153a to the second waterproofing plate 153b forming the side of the enclosed container stacking assistance device 100a to prevent water from flowing into the interior of the cargo hold 17.

[0166] The third waterproof plate 153c disposed along the edge of each of the first long axis frames 111a may have a gap greater than the width of the small container C or the large container C, or the height of the third waterproof plate 153c may be formed to be lower than the height of the first assembly assembly 141 and the second assembly assembly 142 to prevent damage when the small container C or the large container C is fixed to the first assembly assembly 141 and the second assembly assembly 142.

[0167] In other words, unlike the open container stacking assistance device 100, the upper width of the closed container stacking assistance device 100a can be greater than the upper width of the small container C or the large container C.

[0168] As described above, when the enclosed container stacking assistance device 100a equipped with waterproof components 153 is installed on the upper deck 11 at the entrance of the cargo hold 17, and the container C is loaded on top of it, water flows down the side wall of the container C and accumulates on the first waterproof plate 153a. Through the third waterproof plate 153c, the accumulated water will not overflow through the side of the enclosed container stacking assistance device 100a and flow into the cargo hold 17, but can be discharged to the upper deck 11 through the second waterproof plate 153b.

[0169] As described above, the container stacking assistance devices 100, 100a of the present invention can be configured as a simple open type and an open parallel type connected via coupling component 170, or as a simple closed type and a closed parallel type connected via coupling component 170. Here, the open type can be non-waterproof, while the closed type can be waterproof or sealed.

[0170] The container stacking assistance devices 100, 100a of the present invention can be operated in the same way as ISO container C, can be operated with a crane CR to maximize loading convenience, can be loaded and transported from land to transport vehicle TR to facilitate production and logistics, and can reduce the weight of existing 6-row hatch covers by 25% (e.g., about 600 tons based on 15K).

[0171] The container carrier 1 according to an embodiment of the present invention can be as follows: Figures 22 to 26 As shown, it includes a position adjustment component 40 for adjusting the position of the container stacking assistance device 100 and adjusting the number of loading layers of the container stacking assistance device 100.

[0172] The position adjustment assembly 40 is arranged horizontally between each of the adjacent lower compartment guides 31 in the plurality of compartments 18 inside the cargo hold 17, and can be installed at any position along at least one or more of the transverse bulkheads 16 separating the cargo holds.

[0173] The position adjustment assembly 40 can be configured to install the container stacking assistance device 100, which is lowered into the cargo hold 17, via a groove formed on the upper deck 11.

[0174] The position adjustment component 40 may be at least one of the following: fixed stop 41, sliding stop 42, and hinged stop 43a, hinged stop 43b, and hinged stop 43c.

[0175] Position adjustment component 40 can be as follows Figure 22 The fixed stop 41 shown.

[0176] A pair of fixed stops 41 are arranged horizontally between adjacent lower compartment guides 31 in each of the plurality of compartments 18, and can be installed at any position in the vertical direction along the transverse bulkhead 16 to correspond to the protruding component 120 of the container stacking assist device 100, such that the protruding component 120 is installed.

[0177] Alternatively, the position adjustment component 40 can be a sliding stop 42, such as... Figure 23 As shown.

[0178] A pair of sliding stoppers 42 can be mounted to move along a guide rail 42a, which is horizontally mounted on a transverse bulkhead 16, which is located between each of the plurality of lower compartment guides 31 adjacent to each of the compartments 18.

[0179] When the container stacking assist device 100 rises and falls, the sliding stop 42 can be moved left and right so that the protruding component 120 (shown by solid line in the figure) can be installed and can be moved to the middle so that the protruding component 120 does not interfere (shown by dashed line in the figure).

[0180] Additionally, the position adjustment assembly 40 can be a hinged stop 43a, hinged stop 43b, or hinged stop 43c that allows for various rotations, such as... Figure 24 , Figure 25 and Figure 26 As shown in (a) to (c).

[0181] A pair of articulated stops 43a, 43b, and 43c are arranged horizontally between adjacent lower compartment guides 31 in each of the plurality of compartments 18, and can be rotatably mounted on the transverse bulkhead 16 near the location through which the protruding assembly 120 passes.

[0182] When the container stacking assist device 100 rises or falls, the hinged stops 43a, 43b, and 43c can be rotated in one direction to install the protruding component 120 (shown by solid lines in the figure), or they can be rotated in another direction to prevent the protruding component 120 from interfering (shown by dashed lines in the figure).

[0183] Figure 26 (a) is a side view of the hinge stop 43c in a rotated state, (b) is a plan view of the hinge stop 43c showing a state in which it is rotated to allow the protruding component 120 to be installed, and (c) is a plan view of the hinge stop 43c showing a state in which it is rotated to allow the protruding component 120 to pass through.

[0184] As described above, the position adjustment assembly 40 can be composed of various stops such as a fixed stop 41, a sliding stop 42, a hinged stop 43a, a hinged stop 43b, and a hinged stop 43c, and these various stops can be used in parallel.

[0185] For example, when the fixed stop 41 is installed at any position on the transverse bulkhead 16, the sliding stop 42 or the hinged stops 43a, 43b, and 43c are installed at at least one or more positions on the transverse bulkhead 16 above or below the fixed stop 41, so that at least two or more container stacking assistance devices 100 can be installed in each of the plurality of compartments 18 within the cargo hold 17.

[0186] As another example, when the fixed stop 41 is not installed at any position on the transverse bulkhead 16, the sliding stop 42 or the hinged stops 43a, 43b, and 43c are installed at at least one or more positions on the transverse bulkhead 16, such that at least one or more container stacking assistance devices 100 can be installed in each of the plurality of compartments 18 within the cargo hold 17.

[0187] In this invention, in the container carrier 1, lower compartment guides 31, installed at fixed intervals on the side surfaces of the transverse bulkheads 16 within the cargo hold 17, and upper compartment guides 32, installed on the corresponding top platforms 20, 20-1, 20a, 20b, are connected. The ability to continuously load containers C from the bottom of the cargo hold 17 to the top of the upper deck 11 may resemble the open-top design of conventional small container carriers. However, due to the container stacking assistance devices 100, 100a located between the lower compartment guides 31 and the upper compartment guides 32, and the functions of the top platforms 20, 20-1, 20a, 20b, and the upper compartment guides 32 installed on the upper deck 11, the container carrier 1 of this invention can accommodate a large number of containers C, from the bottom of the cargo hold 17 to the top of the upper deck 11, loading 13 or more layers.

[0188] Figure 30 and Figure 31 This is a diagram used to compare the loading stability of containers in a conventional tethering system and the compartment guidance system of the present invention.

[0189] As described above, in the container carrier 1 of the present invention, the existing tethering system applied to the existing tethering platform is omitted, and a compartment guiding system in which an upper compartment guide 32 is provided on the top platform 20 is applied. Subsequently, by referring to Figure 30 and Figure 31 This invention compares and explains the loading stability of container C in the compartment guidance system of the present invention and in existing tethering systems, with the aim of revealing the differences between the present invention and existing inventions.

[0190] Figure 30 (a) shows the load acting on the socket base portion during internal tying in an existing tying system applied to an existing tying platform, and it shows that the compressive load due to its own weight and the lateral load due to the hull motion act as moment components on the socket base portion as additional compressive loads.

[0191] Figure 30 (b) shows the load acting on the socket base during external tethering in an existing tethering system applied to an existing tethering platform, and shows that the compressive load due to its own weight and the lateral load due to hull motion, as moment components, act as additional compressive loads on the socket base, but the aforementioned loads are reduced relative to the internal tethering.

[0192] Figure 30 (c) illustrates an existing zip system applied to an existing zip platform, such as Figure 30 As shown in (a) and (b), transient hull motion loads act as an incomplete element in the hatch cover and tethering system, causing hatch cover movement and relative displacement between the deck platform and the hatch cover and the hull, thereby damaging the socket base. Such damage to the socket base is a major cause of container collapse and loss.

[0193] Figure 31 This invention demonstrates that when the compartment guidance system with an upper compartment guide 32 and container stacking assistance devices 100 and 100a installed on the top platform 20 are applied, the loads acting on the first assembly assembly 141 and the second assembly assembly 142, which serve as the socket base of the container stacking assistance devices 100 and 100a, are absorbed by the upper compartment guide 32 due to the compressive load caused by its own weight and the lateral load caused by the movement of the hull. This prevents the generation of additional compressive forces and ensures that the same margin as the general structural strength of the hull is available to resist the loads caused by the movement of the hull. The effect of the relative displacement of the hull is not significant, and damage to the container C caused by load offset and domino effect caused by the collapse of the tie system can be fundamentally prevented.

[0194] Figures 32 to 34 This is a table used to compare the loading stability of containers in a conventional tethering system and the compartment guidance system of the present invention.

[0195] As described above, in the container carrier 1 of the present invention, the existing rigging system used in existing rigging platforms is omitted, and a compartment guidance system in which an upper compartment guide 32 is provided in the top platform 20 is applied. Subsequently, by referring to Figures 32 to 34 By comparing the loading stability of container C in the compartment guidance system of the present invention with that in the existing tethering system, the differences between the present invention and the prior art are revealed.

[0196] Figure 32 The table shows the results obtained by calculating the lateral deformation force, corner force, and torsional locking force when container C is loaded in 12 layers on top of the upper hatch cover on the upper deck of the ship and the tethering system is used to tie container C in 3 layers in an existing tethering system applied to an existing tethering platform.

[0197] Lateral deformation force is the force exerted on the loaded container C along the tilting direction under the influence of the ship's roll. Angle column force is the vertical force applied to the four columns of the loaded container. Torsion lock force is the force applied to the torsion locks connecting the container through the ship's movement.

[0198] Figure 33 The table shows the results of calculating lateral deformation force, corner force and torsional locking force in the compartment guidance system of the present invention, in which the upper compartment guide 32 is provided on the top platform 20. When the container C is loaded on top of the container stacking assistance device 100 in 12 layers and the compartment guidance system of the container stacking assistance device 100 is applied to a maximum of four layers.

[0199] Figure 34 It shows the basis Figure 32 and Figure 33 The table presents the analysis results of lateral deformation force, corner force, and torsion lock force in the existing tie system and the cabin guidance system of the present invention.

[0200] like Figure 34 As shown, by analyzing the results of the angular column force at the maximum value of motion acceleration when the loaded container C moves left and right during the lateral movement of the container carrier, the permissible value is 848 kN. In comparison, in the case of the existing tethering system (three-layer container tethering platform), the lowest point of the loaded container above the hatch cover has a force of 927.5 kN, which exceeds the permissible value and may lead to a container collapse accident. However, in the case of the compartment guidance system of the present invention (a structure in which four layers of containers are supported by compartment guides to the upper part of the container stacking assistance device of the present invention), because the compartment guides absorb the motion acceleration up to four layers of loaded containers, the maximum value is less than the permissible value of 805.7 kN, so there is no risk of container collapse.

[0201] Furthermore, although not shown, under the same conditions where there are twelve layers of loaded container C and smaller containers (20ft containers) are loaded from the first to the tenth layer, in existing tethering systems, when a 20ft container is loaded onto the top of the hatch cover (where tethering only on one side results in a worse situation than not tethering at all), there is no tethering. However, in the compartment guidance system of the present invention (a structure supported to five layers of containers by compartment guides), the compartment guides support the containers. Therefore, unlike existing tethering systems, the load can be transferred in a purely lateral direction (similar to load transfer within the cargo hold), and under permissible torsion lock loads (minimum breaking force 500kN (per person), 420kN (shear force)), the design safety factor of the present invention can be increased by approximately 8 times compared to existing design safety factors. In other words, when the compartment guidance system of the present invention is applied, superior stability can be expected to be ensured under the conditions of turbulent sea navigation with 20ft containers loaded, compared to existing tethering systems.

[0202] Figure 35 These figures illustrate a method for loading and unloading containers using a container stacking assistance device in a container vehicle according to an embodiment of the present invention. Figure 36 This is a flowchart illustrating a container loading and unloading method using a container stacking assistance device in a container vehicle according to an embodiment of the present invention. Figure 37 This is another flowchart illustrating a container loading and unloading method using a container stacking assistance device in a container vehicle according to an embodiment of the present invention.

[0203] Reference Figure 35 and Figure 36 The present invention will describe a method for loading and unloading containers using container stacking assistance devices 100, 100a in a container carrier 1 according to an embodiment of the present invention.

[0204] In this embodiment, the container stacking assistance devices 100, 100a used in the container loading and unloading method, as described above, may include an upper frame 111 and a lower frame 112, a support member 113, a protruding assembly 120, and a coupling assembly 170, so that at least one cargo compartment 17 of the container carrier 1 used for loading small or large containers C loads the container C on its upper side. The width and length of the upper frame 111 and the lower frame 112 are equal to the width of the small or large container C. The upper frame 111 and the lower frame 112 are 1 to n times the length (n is a natural number), and the upper frame 111 and the lower frame 112 have a planar cross section smaller than the entrance of the cargo hold 17. The support member 113 is arranged along the height direction of the upper frame 111 and the lower frame 112. The protruding component 120 protrudes outward from the upper frame 111 and the lower frame 112 or the support member 113 so that it can be installed at any position in the cargo hold 17. The coupling component 170 connects two or more upper frames 111 and lower frames 112 arranged adjacent to each other.

[0205] The method of loading and unloading containers in the container carrier 1 equipped with container stacking assistance devices 100, 100a will then be described in detail.

[0206] First, the operation of loading container C from land 2 onto container carrier 1 using crane CR will be described.

[0207] The loading of container C into cargo hold 17 is completed by using crane CR (step S11).

[0208] The container stacking assistance devices 100 and 100a are connected in parallel using the coupling assembly 170 (step S12).

[0209] In step S12, it is preferable to connect an odd number of parallel-connected container stacking aids 100, 100a so as to align their center of gravity when transported by the crane CR. In other words, when transporting the container stacking aids 100, 100a using spreaders SR attached to the crane CR, since the spreaders SR are connected to the centrally located container stacking aids 100, 100a in the parallel connection, they need to be connected in an odd number so that the center of gravity can be easily aligned during transport.

[0210] Transport using crane CR in parallel with container stacking assistance devices 100 and 100a (step S13).

[0211] The container stacking assistance devices 100 and 100a are placed on the upper deck 11 at the entrance of cargo hold 17 by using a crane CR, so that the container stacking assistance devices 100 and 100a cover the entrance of cargo hold 17 (step S14).

[0212] In step S14, while the container stacking assistance devices 100 and 100a are stored on land 2, they are transported to the cargo compartment 17 of the container carrier 1 using a crane CR.

[0213] The operation of loading container C onto the upper part of container stacking assist devices 100, 100a is performed by using crane CR, thus completing the loading of container C onto the upper part of container stacking assist devices 100, 100a (step S15).

[0214] The operation of unloading container C from container carrier 1 onto land 2 using crane CR will then be described.

[0215] The operation of unloading the containers loaded on top of the container stacking assistance devices 100 and 100a is performed using the crane CR (step S16).

[0216] The entrance to cargo hold 17 is opened by using a crane CR to remove the container stacking assistance devices 100 and 100a from the entrance of cargo hold 17 (step S17).

[0217] In step S17, the container stacking assistance devices 100 and 100a can be transported in parallel to any position on the upper deck 11 for stowage and storage, and then transported to the land 2 for stowage and storage.

[0218] The operation of unloading container C, which is loaded in cargo hold 17, is performed using crane CR (step S18).

[0219] In this embodiment, when the container carrier 1 includes a hull 10, a cargo hold 17, a lower compartment guide 31, a top platform 20, and an upper compartment guide 32, the upper compartment guide 32 can be installed on the upper deck 11 located at the entrance of the cargo hold 17 using a crane CR while in the state of using the parallel container stacking assistance devices 100, 100a with the coupling assembly 170 (step S12) (step S14), or when removed from the entrance of the cargo hold 17 (step S17), the upper compartment guide 32 can be inserted into the parallel container stacking assistance device 100, 100a. The gap between the container stacking assist devices 100 and 100a is used to guide the rising and falling; the upper deck 11, side plates 12 and bottom plate 13 form the appearance in the hull 10, the cargo hold 17 is separated in the hull 10 by transverse bulkheads 16, the lower hold guide plates 31 are installed at fixed intervals on the sides of the transverse bulkheads 16, the top platform 20 extends to the left and right edges of the upper deck 11 between the cargo holds 17 and is arranged in multiple rows along the length of the hull 10, and the upper hold guide 32 is connected to each lower hold guide 31 and is installed on both sides of the top platform 20.

[0220] Reference Figure 35 and 37 This paper will describe another method for loading and unloading containers in a container transport vehicle 1 using container stacking assistance devices 100, 100a according to an embodiment of the present invention.

[0221] In this embodiment, the container stacking assistance devices 100 and 100a used in the container loading and unloading method, as described above, may include an upper frame 111 and a lower frame 112, a support member 113, and a protruding component 120, so that they can be applied to at least one cargo compartment 17 of the container carrier 1 for loading small or large containers C to load the containers C on its upper side. The width and length of the upper frame 111 and the lower frame 112 are 1 to n times the width and length of the containers C (n is a natural number), and the upper frame 111 and the lower frame 112 have a planar cross-section smaller than the entrance of the cargo compartment 17. The support member 113 is arranged along the height direction of the upper frame 111 and the lower frame 112, and the protruding component 120 protrudes outward from the upper frame 111 and the lower frame 112 or the support member 113 so as to be installed at the entrance of the cargo compartment 17.

[0222] The method of loading and unloading containers in the container carrier 1 equipped with container stacking assistance devices 100, 100a will then be described in detail.

[0223] First, the operation of loading container C from land 2 onto container carrier 1 using crane CR will be described.

[0224] The operation of loading container C into cargo hold 17 is performed by using crane CR, thus completing the loading of container C into cargo hold 17 (step S21).

[0225] The container stacking assistance devices 100 and 100a are placed on the upper deck 11 at the entrance of cargo hold 17 by using a crane CR, and the container stacking assistance devices 100 and 100a cover the entrance of cargo hold 17 (step S22).

[0226] In step S22, the container stacking assistance devices 100 and 100a are transported to the cargo hold 17 of the container vehicle 1 by crane CR while stored on land 2, or are transported to the cargo hold 17 of the container vehicle 1 by crane CR while stored at any position on the upper deck 11 of the container vehicle 1.

[0227] The operation of loading container C onto the upper part of container stacking assist devices 100 and 100a is performed by using crane CR, thus completing the loading of container C onto the upper part of container stacking assist devices 100 and 100a (step S23).

[0228] The operation of unloading container C from container transport vehicle 1 onto land 2 using crane CR will then be described.

[0229] The operation of unloading the containers loaded on top of the container stacking assistance devices 100, 100a is performed using the crane CR (step S24).

[0230] By using the crane CR to remove the container stacking assistance devices 100 and 100a from the entrance of cargo hold 17, and simultaneously unloading the removed container stacking assistance devices 100 and 100a to land 2 or transporting them to any location on the upper deck 11, the entrance of cargo hold 17 is opened (step S25).

[0231] In step S25, the container stacking assistance devices 100, 100a can be transported to any location on the upper deck 11 for loading and storage on the upper deck 11, and transported to the land 2 for stowage and storage on the land 2.

[0232] The operation of unloading container C, which is loaded in cargo hold 17, is performed using crane CR (step S26).

[0233] In this embodiment, when the container carrier 1 includes a hull 10, a cargo hold 17, a lower compartment guide 31, a top platform 20, and an upper compartment guide 32, in step S25 of opening the entrance to the cargo hold 17, the container stacking assistance devices 100 and 100a can be stored between the top platforms 20 facing each other in the fore-and-aft direction on the upper deck 11, or they can be stored on the land 2. In the hull 10, the upper deck 11, side plates 12, and bottom plate 13 form the exterior. The cargo hold 17 is separated inside the hull 10 by transverse bulkheads 16. The lower compartment guide 31 is installed at fixed intervals on the sides of the transverse bulkheads 16. The top platform 20 extends to the left and right edges of the upper deck 11 between the cargo holds 17 and is arranged in multiple rows along the length of the hull 10. The upper compartment guide 32 is connected to each lower compartment guide 31 and is installed on both sides of the top platform 20.

[0234] Figure 38 and Figure 39 This is an explanation Figure 17 and Figure 18 Perspective and plan views of another embodiment of the container stacking assistance device.

[0235] like Figure 38 and Figure 39 As shown, in the container stacking assistance device 100b according to another embodiment, and... Figure 17 The open container stacking assist device 100 shown is closed on both sides by the first plate 151 and the second plate 152, and open at the top, bottom, front, and rear. Figure 18 Compared to the enclosed container stacking assistance device 100 shown, which is sealed on the left and right sides by the first plate 151 and the second plate 152 and sealed on the top and front and rear sides by the waterproof component 153, the basic configuration may be the same or similar, but the structure may be different. It is a multi-modal container stacking assistance device formed by at least two or more open container stacking assistance devices 100 or enclosed container stacking assistance devices 100a arranged in the width direction.

[0236] In other words, assuming that the open container stacking assist device 100 or the closed container stacking assist device 100a is a single type for loading a row of containers C, the container stacking assist device 100b according to another embodiment can be defined as a multi-type device configured to load at least two or more rows of containers C in the width direction.

[0237] According to another embodiment, the container stacking assistance device 100b may include a main body and a protruding component 120. The main body consists of at least two or more unit bodies 110a arranged in the width direction and a connecting member 190 connecting adjacent unit bodies 110a. The protruding component 120 protrudes outward from each unit body 110a so as to be installed at any location in the cargo compartment 17.

[0238] In the foregoing, since unit 110a has the same or similar basic configuration as the main body 110 of open container stacking assistance device 100 or closed container stacking assistance device 100a, similar reference numerals are used for similar configurations. Accordingly, detailed descriptions of each identical component will be omitted here to avoid repetition, and configurations that vary according to multiple types of configurations will be described in detail.

[0239] In unit 110a, the upper frame 111, lower frame 112, and support member 113 can be combined with each other to form an overall rectangular box shape. The upper frame 111 and lower frame 112 have planar cross-sections, the width of which corresponds to the width of container C and its length is less than the entrance of cargo hold 17. The support member 13 is disposed between the upper frame 111 and lower frame 112 along the height direction. Here, the support member 113 connects each square corner of unit 110a, and the protruding component 120 protrudes outward from the lower end of each support member 113.

[0240] Unit 110a may be provided in at least two or more units corresponding to the width interval of the lower compartment guide 31.

[0241] The width of the connecting component 190 corresponds to the width of the lower compartment guide 31 and can connect adjacent units 110a.

[0242] When the configuration of unit 110a is the same as or similar to that of the main body 110 of the aforementioned open container stacking assistance device 100, the connecting member 190 can be welded to the first long axis frame 111a in the adjacent unit 110a by means of an attachment width unit, or it can be configured as a component with two facing first long axis frames 111a. Although not shown in the figure, in order to enhance structural rigidity, the lower part of the connecting member 190 (inside the container stacking assistance device 100b) can be provided with a reinforcing structure such as a reinforcing rib, such as a longitudinal reinforcing component or a transverse reinforcing component.

[0243] Additionally, when the configuration of unit 110a is the same as or similar to that of the main body 110 of the aforementioned enclosed container stacking assist device 100a, the connecting member 190 can be welded to the first long axis frame 111a in the adjacent unit 110a by means of an attachment width unit, or it can be formed from a single plate when viewed from top to bottom on the upper surface of the container stacking assist device 100b. Although not shown in the figures, to enhance structural rigidity, the lower part of the connecting member 190 and the waterproof plate 153c (inside the container stacking assist device 100b) can be provided with reinforcing structures such as reinforcing ribs, longitudinal reinforcing components, or transverse reinforcing components.

[0244] In the aforementioned enclosed container stacking assistance device 100a, the upper part, front side, and rear side of the main body 110 are sealed with waterproof components 153, and in the container stacking assistance device 100b according to another embodiment, the upper part, front side, and rear side of the unit body 110a can also be sealed with waterproof components 153.

[0245] According to another embodiment, the waterproofing component 153 of the container stacking assistance device 100b may include a first waterproofing plate 153a, a second waterproofing plate 153b, and a third waterproofing plate 153c. The first waterproofing plate 153a is installed on the upper part of each unit 110a, the second waterproofing plate 153b is installed on the front and rear sides of each unit 110a, and its lower end protrudes outward corresponding to the shape of the protruding component 120 and is located on the upper deck 11 at the entrance of the cargo hold 17. The third waterproofing plate 153c is installed at a certain height along the upper two side edges of each unit 110a. Water accumulated on the first waterproofing plate 153a of each unit 110a is guided to the second waterproofing plate 153b of each unit 110a through the third waterproofing plate 153c. When the waterproofing component 153 of the container stacking assistance device 100b of another embodiment is configured in this way, the connecting member 190 may further include a waterproofing plate connecting the first waterproofing plates 153a of adjacent units 110a.

[0246] The waterproof plate of the connecting component 190 can be separately provided to connect the first waterproof plates 153a of adjacent unit bodies 110a, or it can be integrally formed by extending the first waterproof plate 153a.

[0247] As described above, the third waterproofing plate 153c is installed at a certain height along the upper two sides of each unit body 110a. However, when at least two or more unit bodies 110a are arranged in the width direction, it can be formed at the upper left edge of the unit body 110a arranged on the left and the upper right edge of the unit body 110a arranged on the right. In other words, the third waterproofing plate 153c can be installed at a certain height along the upper two sides of the main body, which is formed by arranging at least two or more unit bodies 110a in the width direction.

[0248] In addition, the container stacking assistance device 100b according to another embodiment may further include a guide groove 195, which is formed to be recessed inward to a certain depth from both sides of the connecting member 190.

[0249] The guide groove 195 can be formed to slide in the lower compartment guide 31 or the upper compartment guide 32 connected to the lower compartment guide 31 and extending a certain length to the upper part of the upper deck 11, so as to guide the rise and fall of the container stacking assistance device 100b.

[0250] Additionally, according to another embodiment, the container stacking assistance device 100b may further include an assembly assembly for securing the container C, which is disposed on the upper surface of the upper frame 111 and loaded on the upper frame 111.

[0251] The assembly components may be the same as or similar to the assembly components of the open container stacking assistance device 100 or the closed container stacking assistance device 100a described above.

[0252] In other words, the assembly assembly includes a first assembly assembly 141 for securing the large container C and a second assembly assembly 142 for securing the small container C, wherein the second assembly assembly 142 may share at least a portion of the first assembly assembly 141 to secure the small container C.

[0253] According to another embodiment of the above configuration, the container stacking assistance device 100b is formed by connecting at least two or more unit bodies 110a arranged in the width direction by connecting member 190, wherein the unit bodies 110a are preferably arranged in an odd number, such that the first assembly assembly 141 and the second assembly assembly 142 located in the unit body 110a located in the center can be used for hoisting when transported by crane CR.

[0254] As described above, in this embodiment, by providing top platforms 20, 20-1, 20a, and 20b equipped with upper compartment guides 32, the container C can be supported and secured by the upper compartment guides 32, eliminating the need for existing tethering systems (such as fastening devices for tethering rods and tethering bars), thus reducing material costs and the time and money spent on tethering work. Furthermore, during the operation of the container carrier 1, by directly supporting the container C on the upper deck 11, the problem of damage or loss of the loaded container C can be solved. Additionally, since the upper compartment guides 32 provided on the top platforms 20, 20-1, 20a, and 20b are respectively connected to the lower compartment guides 31 installed on the transverse bulkhead 16, loading and unloading of the container C can be performed continuously without additional work such as installing hatch covers or tethering.

[0255] In addition, by configuring the container stacking assistance devices 100, 100a, and 100b to be installed at the entrance of the cargo hold 17 of the container carrier 1, this embodiment not only helps the longitudinal strength of the hull 10 when installed at the entrance of the cargo hold 17, but also transfers the load of the containers C loaded on the upper deck 11 to the hull 10. Therefore, it can stack a large number of containers C, including those loaded from the bottom of the cargo hold 17 to the upper part of the upper deck 11, up to thirteen or more layers.

[0256] In addition, in this embodiment, by configuring the container stacking assistance devices 100, 100a, and 100b to be able to transport one or more by the crane CR and stack themselves, they can be easily handled to be installed at the cargo compartment 17 entrance of the container carrier 1, facilitating storage on the container carrier 1 or on land 2, and facilitating transport by the transport vehicle TR on land 2.

[0257] In addition, in this embodiment, since the container stacking assistance devices 100, 100a, and 100b are provided with all or part of the reinforcing frame 130, the first plate 151 and the second plate 152, and the reinforcing component 160, the rigidity that can support the load of the container C loaded on top can be ensured.

[0258] In addition, in this embodiment, by providing a first assembly component 141 and a second assembly component 142 corresponding to the corner castings of the container C on the upper surface of the container stacking assistance devices 100, 100a, and 100b, not only can the containers loaded on the upper surface be securely fixed, but also 20-foot small containers C and 40-foot large containers C can be stacked together.

[0259] Furthermore, in this embodiment, by forming the top platforms 20, 20-1, 20a, and 20b into a compartment guidance system that omits the tethering platform and connects the upper compartment guide 32 and the lower compartment guide 31 mounted on the transverse bulkhead 16 to each other, compared with the existing tethering platform, not only can the width be minimized, but the complex structure of installing the existing tethering platform can be formed into a simple structure. Moreover, since the width of the upper deck 11 between the cargo holds 17 can be minimized compared with the existing container carrier with the existing tethering platform, design flexibility (due to the optimization possibilities caused by eliminating the hull length and other tethering systems) or increased transport capacity of the container C can be ensured compared with the container carrier 1 of the same specifications.

[0260] In addition, in this embodiment, by providing a position adjustment component 40 for adjusting the position of the container stacking assistance devices 100, 100a, and 100b, one or more container stacking assistance devices 100, 100a, and 100b can be installed at any position within the cargo hold 17, thereby increasing the flexibility of loading containers C.

[0261] In addition, in this embodiment, by providing hull extension members 50 protruding to the left and right sides of the hull 10, the container C can be additionally loaded into the hull extension members 50. This not only increases the loading capacity of the container C, but also reduces the possibility of wave intrusion by making the outer side plate 12a portion constituting the hull extension member 50 inclined outward.

[0262] In addition, in this embodiment, the bending moment of the hull 10 can be improved by installing reinforced bulkheads 60 at the edges of the upper deck 11 on the left and right sides of the hull 10.

[0263] In addition, in this embodiment, by providing a drain outlet 70 in the freeboard deck 19 to penetrate the side plate 12 of the double hull structure to the outside, providing a support structure 80 for supporting the container C at fixed intervals at the bottom of the inner bottom plate 13b, and providing a drainage system 90 on the bottom plate 13, water introduced through the cargo hold 17 inlet of the container carrier 1 can be easily handled, and the container C located at the bottom of the cargo hold 17 can be prevented from being submerged in water.

[0264] While the present invention has been described above with reference to embodiments thereof, this is merely exemplary and does not limit the invention. Those skilled in the art will understand that various combinations, modifications, and applications not illustrated in the embodiments are possible without departing from the essential technical content of these embodiments.
