Description

Technology Field

[0001] The present invention relates to a container loading device and a ship including the same. Background Technology

[0002] Generally, a container ship is a vessel that organizes various types of containers into units of a fixed size and transports them by loading them onto the deck or in the cargo holds inside the hull.

[0003] Container ships are increasingly expanding their container loading capacities to reduce transportation costs, and as this capacity grows, ensuring the stability of loaded containers during operation is becoming a critical factor. To guarantee container stability during transit, a structure called a "cell guide" is applied to the cargo holds inside the hull, and various securing devices are installed on the upper deck (above the hatch covers).

[0004] Devices for securing containers loaded on the upper deck include twist locks, lashing bridges, and lashing bars.

[0005] Container carriers are generally equipped with lashing bridges at the level of approximately 1 to 4 tiers. These lashing bridges enable the fastening of lashing bars to prevent containers from tipping over, thereby allowing for the lashing of containers. In addition to the function of fastening using lashing bars, lashing bridges provide access and workspace for the maintenance and monitoring of control units installed in reefer containers loaded on the deck. Since lashing bridges are essential for fastening lashing bars at the fore and aft of containers, they must have a width equal to the ship's width, withstand the load of the lashing bars, and be constructed as high-strength and heavy-weight structures to meet the dimensional requirements for securing workspace.

[0006] Among the containers loaded on the deck of a container ship, for containers loaded at the level of a lashing bridge, lashing is secured using a lashing bar that connects the lashing bridge and the container as described above; however, for containers loaded at a level higher than the height of the lashing bridge, access by workers is impossible, so only a basic fastening device, a twistlock, is applied.

[0007] In the case of Twist Locks capable of automatic and semi-automatic fastening, fastening and unfastening require minimal work time, whereas lashing bars that cannot be automatically fastened present a problem in that fastening and unfastening take a significant amount of time.

[0008] Therefore, to reduce the time required for container fastening and unfastening, a method has been proposed to apply guiding sections not only to the cargo holds but also to the lashing bridges located on the upper deck. However, when guiding sections are installed on the lashing bridges, structural interference occurs between the guiding sections and the hatch covers because the size of the hatch covers that open and close the cargo holds is larger than the space between the lashing bridges where the guiding sections are installed.

[0009] In particular, since a large number of containers can be loaded on the top of the hatch cover, it must be constructed of a high-strength and heavy-weight structure. As a result, it is impossible to operate the opening and closing with the strength of a worker, making it unavoidable to use a crane on a ship or on land. Therefore, when a guiding part is installed on the lashing bridge as described above, a solution is required to overcome structural interference during the transfer and opening / closing of the hatch cover. The problem to be solved

[0010] 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 device and a ship including the same, which secures a container loaded on the upper deck of a ship through a guiding part connected to a lashing bridge, while ensuring that the guiding part provided on the lashing bridge does not interfere with the vertical movement of a hatch cover. means of solving the problem

[0011] The present invention relates to a container loading device provided in a ship having a hull internal cargo hold having a cell guide and a hatch cover placed on the upper deck, wherein the container is loaded on the hatch cover, and may include a plurality of lashing bridges arranged on the upper deck and a guiding member provided on the lashing bridges to support the container.

[0012] Specifically, the guiding member is provided on only one side between a pair of lashing bridges facing each other, and is aligned vertically with the cell guide placed inside the cargo hold, and the hatch cover can be inserted through the space between one of the lashing bridges where the guiding member is provided and the other lashing bridge where the guiding member is not provided.

[0013] Specifically, the space between one of the lashing bridges provided with the guiding part and another lashing bridge not provided with the guiding part is,

[0014] It is arranged to be at least partially offset in the horizontal direction from the entrance of the cargo hold, thereby inducing horizontal movement of the hatch cover.

[0015] Specifically, the guiding member can be installed at a height higher than the height of the lashing bridge and is spaced apart from the upper deck, and the spaced-apart height is higher than the thickness of the hatch cover so that the hatch cover can move horizontally on the upper deck, and the space between one of the lashing bridges provided with the guiding member and another lashing bridge not provided with the guiding member has a gap longer than the length of the hatch cover, and the other lashing bridge not provided with the guiding member may include a container fastening function using the lashing bar.

[0016] Specifically, the hatch cover can be vertically transported in contact with the guiding part in the space between one of the lashing bridges provided with the guiding part and another lashing bridge not provided with the guiding part, reaching the upper deck while preventing structural interference caused by the hatch cover's displacement, and can be horizontally transported and positioned on the upper deck.

[0017] Specifically, the cargo hold further includes a cargo hold inner wall that determines the size of the cargo hold and withstands the load of the upper deck, and a rectangular hopper tank having the same shape as the container, and when the container is loaded into the cargo hold, it is positioned in contact with cell guides placed on both sides of the cargo hold inner wall, and when loaded onto the upper deck, it is loaded on the top of the hatch cover, and one side of the container is in contact with the guiding part placed on the lashing bridge, and the opposite side of the container can be fixed to the lashing bridge through the lashing bar.

[0018] Specifically, the length of the hatch cover is formed to be longer than the length of the container so that the container can be loaded within the upper area of ​​the hatch cover.

[0019] A vessel according to an embodiment of the present invention is equipped with the container loading device. Effects of the invention

[0020] The container loading device according to the present invention and the ship including the same can improve work efficiency and ensure stability by reducing the time required for fastening and unfastening containers by placing a guiding part on the lashing bridge on the upper deck, and can overcome structural interference between the hatch cover and the guiding part during vertical transport of the hatch cover through the placement of the guiding part.

Specific details for implementing the invention

[0022] 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.

[0023] Before describing the present invention, a conventional lashing bridge (3) and a cargo hold (7) will be described first with reference to FIGS. 1 and FIGS. 2.

[0024] Preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0025] FIG. 1 is a cross-sectional view of a conventional lashing bridge (3), and FIG. 2 is a cross-sectional view of a cargo hold (7) included in a container ship.

[0026] A container ship can load and transport standard cargo, such as containers (2). The container ship is equipped with multiple cargo holds (7) inside the hull, and can sequentially load and transport multiple containers (2) into these cargo holds (7). Such a container ship can be manufactured and operated in various forms and structures depending on the loading method or unloading method of the containers (2).

[0027] Referring to FIG. 1, a cargo hold (7) is provided in the lower direction relative to the upper deck (6) of the ship, and a lashing bridge (3) is provided in the upper direction.

[0028] Generally, the container (2) can be loaded inside the cargo hold (7) or on top of the hatch cover (5) that opens and closes the cargo hold (7).

[0029] Containers (2) loaded inside the cargo hold (7) are positioned to be in contact with the cell guide (1), and containers (2) loaded on the upper deck (6) or on the top of the hatch cover (5) of the ship are secured to the lashing bridge (3) using a lashing bar (8) so as to prevent tipping over during operation.

[0030] Lashing bridges (3) are mainly installed on large container ships (5000 TEU or more), and lashing bridges (3) may be installed on most ships to reduce the risk of overturning containers (2) and increase stability when containers (2) are stacked high.

[0031] Lashing bridges (3) are spaced apart along the width direction of the hull and can be installed on the upper deck (6) of the ship. The height of the lashing bridges (3) can be installed at a height capable of supporting multiple layers of containers (2) loaded, and as container ships have recently become larger and the number of layers of loaded containers (2) has increased, the height of the lashing bridges (3) has also increased from the existing 2 layers to 3 layers, and the height can reach 10m or more.

[0032] The lashing bridge (3) may include a lashing bridge support (31) and a lashing bridge support frame (32).

[0033] Hereinafter, the lashing bridge support (31) is referred to as the support (31), and the lashing bridge support frame (32) is referred to as the support frame (32).

[0034] The lashing bridge (3) may have an H-shaped structure and may have supports (31) on both sides that can secure the container (2), and the supports (31) may be spaced apart at intervals equal to the length of the short edge of the container (2).

[0035] A support frame (32) may be positioned between the supports (31) placed on both sides, and the supports (31) may be connected to and fixed to the support frame (32). At this time, various methods of connection, such as welding or bolting, are possible.

[0036] The size of the support frame (32) varies depending on the purpose of the lashing bridge (3), but it can be configured as a passageway large enough for people to pass through. Therefore, it is possible to check whether the container (2) is securely fixed by the support (31) from the top of the support frame (32).

[0037] During the operation or anchoring of the ship, vibrations may occur in the lashing bridge (3) due to waves or wind. If these vibrations persist for a long time, they may have the characteristics of natural vibrations, causing the lashing bridge (3) to break or bend and fail to properly support the container (2).

[0038] In addition, since the lashing bridge (3) supports the weight of the container (2), increasing the weight may be unavoidable to ensure the rigidity of the lashing bridge (3), and to compensate for this, there is a method of increasing the thickness of the lashing bridge (3), but this method can result in increasing the weight and placing a burden on the ship.

[0039] The container (2) can be secured by connecting both sides of the container (2) to the lashing bridge (3) with lashing bars (8). The connection between the lashing bars (8) and both sides of the container (2) is not automatically connected, so there is a problem that it takes a huge amount of time to connect and disconnect, and there is also a risk factor in terms of work safety because workers must install it at a high place.

[0040] Although many methods have been proposed to solve these problems, the lashing bridge (3) is directly related to the operation of the ship, along with the loading of containers (2) and hatch covers (5), so it is difficult to independently change the type and arrangement method of the lashing bridge (3).

[0041] However, many of the problems described above can be solved through the container loading device of the present invention, which will be explained later in FIGS. 3, 4, and 5.

[0042] The cargo hold (7) is located in the lower direction relative to the upper deck (6) of the ship and is a space for loading cargo between the engine room bulkhead and the bow bulkhead, and its shape may vary depending on the shape of the cargo being transported.

[0043] Referring to FIG. 2, the cargo tank (7) may have a cargo tank inner wall (71) that separates the cargo tank (7), and cell guides (1) may be placed on both sides of the cargo tank inner wall (71). The cell guides (1) may be directly attached to the cargo tank inner wall (71), or they may be spaced apart from the cargo tank inner wall (71) as needed. Additionally, the cell guides (1) may be composed as a single unit and placed vertically on the inner wall, or they may be divided into units and placed on the cargo tank inner wall (71) in the form of parts.

[0044] Cell guides (1) can be installed in multiple numbers at regular intervals on the inner wall (71) of the cargo hold, and can serve as guides when loading or unloading containers (2) to enable efficient transport, and can be placed between a loaded container (2) and an adjacent container (2) to prevent the container (2) from tipping over, thereby enabling stable transport.

[0045] The cell guide (1) may have a vertical plate shape, and if necessary, two members may form one cell guide (1). Additionally, the cell guide (1) may be composed of members connected integrally, or the cell guide (1) itself may be divided into separate parts with a portion omitted.

[0046] Referring to FIG. 2, a rectangular shape protruding from the interior space of the cargo hold (7) can be seen. This is a hopper tank (72) and can be installed on the lower left and right sides of the ship. The hopper tank (72) can perform the function of reducing the lateral movement of the ship.

[0047] In a general ship, the hopper tank (72) is formed in a diagonal shape, but in the case of a container ship, since containers (2) are loaded in the cargo hold (7), a hopper tank (72) having the shape of a container (2) can be arranged. Therefore, containers (2) can be loaded on top of the hopper tank (72).

[0048] FIG. 3 is a cross-sectional view of a container loading device according to one embodiment of the present invention, and FIG. 4 is a cross-sectional view of a container (2) loaded on a container loading device according to one embodiment of the present invention.

[0049] The following describes the components constituting the container loading device.

[0050] The container loading device includes a lashing bridge (3), a lashing bar (8), and a guiding part (4), and the vessel on which the container loading device is provided may have a hatch cover (5).

[0051] The lashing bridge (3) is a structure that can secure a container (2) loaded on the upper deck (6) or on the top of a hatch cover (5) of a ship using a lashing bar (8), and is positioned on the upper deck (6), and multiple bridges may be positioned.

[0052] The lashing bridge (3) may have an H-shaped structure and may have vertical supports (31) that can fix the container (2) on both sides, and the supports (31) may be spaced apart at intervals equal to the length of the short edge of the container (2).

[0053] A support frame (32) may be positioned between the supports (31) placed on both sides, and the supports (31) may be connected to and fixed to the support frame (32). At this time, various methods of connection, such as welding or bolting, are possible.

[0054] The size of the support frame (32) varies depending on the purpose of the lashing bridge (3), but it can be configured as a passageway large enough for people to pass through. Therefore, it is possible to check whether the container (2) is securely fixed by the support (31) from the top of the support frame (32).

[0055] Additionally, referring to FIG. 3, a guiding member (4) may be connected to the lashing bridge (3). The lashing bridge (3) and the guiding member (4) may be connected in contact or separated.

[0056] The distance between the lashing bridge (3) and the guiding section (4) may vary depending on the design, but the space between one lashing bridge (3) with the guiding section (4) and another lashing bridge (3) without the guiding section (4) may have a gap longer than the length of the hatch cover (5).

[0057] In addition, the space between one lashing bridge (3) provided with a guiding section (4) and another lashing bridge (3) not provided with a guiding section (4) is provided at least partially offset in the horizontal direction from the entrance of the cargo hold (7) to induce horizontal movement of the hatch cover (5).

[0058] The lashing bar (8) is a fixing device that can be used for containers (2) loaded on the upper deck (6) of a ship. It can also be used when containers (2) are loaded in 4 layers or less, and it serves to fix the containers (2) by connecting to the lashing bridge (3) or the deck.

[0059] Even if the container (2) is spaced apart from the lashing bridge (3) or is in contact with the lashing bridge (3), the corners of the lashing bridge (3) and the container (2) can be connected through the lashing bar (8) to secure the container (2).

[0060] Devices used in the lashing bar (8) may include lashing rods or turnbuckles. Turnbuckles are used in places where length adjustment or tension adjustment is required for ropes or wires, and can be used to pull or loosen general ropes or chains.

[0061] The turnbuckle is used such that one male screw is a right-hand screw and the other male screw is a left-hand screw, so when the nut, which is the part with the female screw, is rotated, the two male screws move closer together, and when the rotation is reversed, they move further apart.

[0062] Types of turnbuckles include forged turnbuckles, squeegee turnbuckles, and cast turnbuckles, and among them, forged turnbuckles have three types: I&I, Jaw & Jaw, and Hook-Ac-Hook.

[0063] Depending on the method of use, one side can be changed to a different type, and generally, forged turnbuckles are used for tasks requiring tensile strength.

[0064] The turnbuckle can be used for many purposes as it is adjustable in length and allows the use of a single type of rod, making it easy to handle and reducing working time. The fixing method of the lashing bar (8) can be a vertical lashing fixed in a vertical direction, a cross lashing fixed in a horizontal direction, or a mixed lashing that combines the two.

[0065] Referring to FIG. 4, one side of the container (2) loaded on the hatch cover (5) is fixed in contact with the guiding part (4), and the opposite side is fixed to the lashing bridge (3) through the lashing bar (8).

[0066] In the container (2) loading operation, the transfer and loading of the container (2) can be done through the crane's spreader, so it does not take much time. However, the fastening and unfastening of the lashing bar (8) cannot be done automatically and must be done manually, which takes a huge amount of time, and there is a risk factor in terms of work safety as workers must install it at a high place.

[0067] When containers (2) are loaded in multiple layers on the upper deck (6) of a ship, the lashing bar (8) fastening operation for containers (2) loaded higher than the lashing bridge (3) is essential and therefore accounts for the majority of the container (2) loading operation.

[0068] Unlike conventional lashing bridges (3), the container loading device of the present invention can minimize or omit the fastening of the lashing bar (8) by fixing one side of the container (2) with a guiding part (4), and fix the opposite side of the container (2) through the lashing bar (8). Therefore, the work of fastening and unfastening the container (2) can be eliminated by about 50%, thereby improving work efficiency and safety.

[0069] Referring to FIG. 4, the guiding part (4) is positioned on the lashing bridge (3) to support the container (2).

[0070] The guiding section (4) can perform the function of fixing the side of the container (2), similar to the cell guide (1) which is placed on the lashing bridge (3) and on the inner wall (71) of the cargo hold. However, while the cell guide (1) placed on the inner wall (71) of the cargo hold is placed on both sides of the inner wall (71) of the cargo hold, the guiding section (4) can be placed on only one side in the space between the lashing bridge (3) and the lashing bridge (3).

[0071] Additionally, the guiding section (4) can be aligned vertically with the cell guide (1), allowing containers (2) of the same size to be loaded onto the upper deck (6) and the cargo hold (7).

[0072] The guiding section (4) can be installed higher than the height of the lashing bridge (3), and the guiding section (4) and the upper deck (6) can be spaced apart. Since space is required for the hatch cover (5), which serves as a cover for the cargo hold (7), to be transported horizontally on the upper deck (6), the guiding section (4) may be spaced apart from the upper deck (6) by at least the thickness of the hatch cover (5).

[0073] The shape of the guiding part (4) may have a vertical plate shape, and if necessary, two members may form one guiding part (4).

[0074] The container loading device of the present invention loads the container (2) so that it is not loaded directly onto the lashing bridge (3), and the container (2) can be secured using the lashing bar (8) and the guiding part (4). Therefore, the load of the container (2) acting on the lashing bridge (3) can be minimized.

[0075] The hatch cover (5) serves to open and close the cargo hold (7) and can also prevent foreign substances from entering the cargo hold (7). Additionally, since a number of containers (2) can be loaded on the top of the hatch cover (5), the hatch cover (5) must be constructed as a heavy structure.

[0076] Therefore, since the hatch cover (5) cannot be opened or closed by the strength of a worker, the hatch cover (5) can be moved using a crane on a ship or on land to open or close the cargo hold (7). Because there is a limit to the horizontal movement of the hatch cover (5) due to the limited working radius of the crane, the movement of the hatch cover (5) is generally carried out in the vertical direction.

[0077] Referring to FIG. 3, since the cargo tank (7) is located between the lashing bridges (3), the hatch cover (5) must pass between the lashing bridges (3) to be transported to the top of the cargo tank (7).

[0078] If the guiding section (4) is spaced apart on both sides of the lashing bridge (3), the gap between the guiding sections (4) may be shorter than the length of the hatch cover (5). In this case, structural interference may occur between the guiding section (4) and the hatch cover (5), making it impossible to move and open / close the hatch cover (5) in the vertical direction.

[0079] In order to solve these problems, the container loading device of the present invention may have a guiding member (4) placed on only one side in the space between the lashing bridge (3) and the lashing bridge (3). Accordingly, the gap between the lashing bridge (3) and the guiding member (4) that is not connected to the guiding member (4) may have a gap longer than the length of the hatch cover (5).

[0080] Referring to FIG. 3, the hatch cover (5) can be transported vertically while in contact with the guiding part (4) in the gap between the guiding part (4) and the lashing bridge (3), thereby reaching the upper deck (6) while preventing structural interference caused by the hatch cover (5) moving out of position. After reaching the upper deck (6), the hatch cover (5) can be transported horizontally to the upper deck of the cargo hold (7).

[0081] A container (2) can be loaded on top of a hatch cover (5). However, if the container (2) is loaded in a way that is off-center on one side of the hatch cover (5), the load of the container (2) may not be concentrated at the end of the hatch cover (5) but may be concentrated at the center of the hatch cover (5), which is more vulnerable, and thus deformation such as twisting may occur in the hatch cover (5).

[0082] In the present invention, as shown in FIG. 4, if a container (2) is loaded within the upper area of ​​a hatch cover (5) or if the center of the hatch cover (5) and the container (2) are aligned, one side of the container (2) comes into contact with the guiding part (4) and the opposite side is separated from the lashing bridge (3) and is fixed through the lashing bar (8).

[0083] In this case, the load of the container (2) can be concentrated at the location where the upper deck (6), which is the end of the hatch cover (5), and the hatch cover (5) meet, thereby preventing deformation of the hatch cover (5).

[0084] FIG. 5 is a cross-sectional view of a container loading device according to another embodiment of the present invention, FIG. 6 is a perspective view of a horizontal moving part (41) which is a component of a container loading device according to another embodiment of the present invention, and FIG. 7 is a cross-sectional view of a horizontal moving part (41) which is a component of a container loading device according to another embodiment of the present invention.

[0085] A container loading device according to another embodiment of the present invention may include a guiding part (4) and a horizontal moving part (41) that support a container (2) by being connected to a plurality of lashing bridges (3) arranged on the upper deck (6).

[0086] Hereinafter, other embodiments of the present invention will be described primarily in terms of how they differ from the preceding embodiments, and any parts omitted from the description will be replaced by the preceding content.

[0087] In a container loading device according to another embodiment of the present invention, unlike the previous embodiment, the guiding part (4) may be positioned on both sides of the lashing bridge (3). As previously explained, if the guiding part (4) is positioned spaced apart on both sides of the lashing bridge (3), structural interference occurs, making it impossible to move and open / close the hatch cover (5) in the vertical direction.

[0088] A container loading device according to another embodiment of the present invention includes a horizontal moving part (41) in the guiding part (4) positioned on both sides of the lashing bridge (3) to solve these problems, thereby enabling the spacing between the guiding parts (4) to be adjusted through the horizontal movement of the guiding part (4).

[0089] Referring to FIG. 5, the guiding sections (4) can be moved horizontally so that the space between the guiding sections (4) is made longer than the length of the hatch cover (5).

[0090] In addition, referring to FIGS. 3 and 4 described above, unlike the conventional lashing bridge (3), the container loading device can fix one side of the container (2) with a guiding part (4) and fix the opposite side of the container (2) through a lashing bar (8). Therefore, the work of fastening and unfastening the container (2) can be eliminated by 50%.

[0091] In contrast, a container loading device according to another embodiment of the present invention can secure both sides of the container (2) with guiding parts (4), so that securing through a lashing bar (8) may not be necessary. Therefore, the work of securing and unsecuring the container (2) can be 100% eliminated, thereby further improving work efficiency and stability.

[0092] Additionally, the guiding part (4) may be configured as an integrated unit or as a separate unit. In the case where the guiding part (4) is configured as a separate unit, a horizontal movement unit (41) may be individually connected to the separated guiding part (4), so that the position of the separated guiding part (4) can be individually adjusted.

[0093] The horizontal moving part (41) may include a slide block (411) connected to the guiding part (4), a roller (412) that allows the slide block (411) to slide, a handle (413) attached to the slide block (411) that allows the position of the slide block (411) to be adjusted by manual operation, and a fixing pin (414) inserted between the roller (412) and penetrating the slide block (411) to fix the slide block (411).

[0094] The slide block (411) is a connecting member connected to the guiding part (4) and slides through the roller (412) inside the horizontal moving part (41) to transport the guiding part (4).

[0095] Referring to FIG. 6, it is possible to slide in both directions, but referring to FIG. 7, there is a hole at the end of the slide block (411) into which a fixing pin (414) is inserted, so although it is possible to slide in both directions, there may be a limitation on the distance of movement. The slide block (411) may be made of the same material as the guiding part (4), and since it can also perform the role of supporting the guiding part (4), it may be made of a rigid material.

[0096] Additionally, the slide block (411) may have an uneven structure (416) through which a fixing pin (414) can pass, so that the slide block (411) can be fixed by applying the fixing pin (414) to the uneven structure (416). One or more uneven structures (416) may be arranged along the length direction of the slide block (411).

[0097] The roller (412) is a device that enables the slide block (411) to slide inside the horizontal moving part (41). The roller (412) can be a metal ball, or it can be in the form of a flat wheel made of alloy or plastic.

[0098] Referring to FIG. 7, multiple rollers (412) may be arranged inside the horizontal moving part (41). Multiple rollers may be arranged above and below the slide block (411), and the rollers (412) above and below may be arranged in a straight line with each other so as not to be misaligned.

[0099] A vertical fixing pin (414) can be inserted between the rollers (412) and the rollers (412), and for safety, a permanent fixing pin (415) is placed near the guiding part (4) so ​​that the slide block (411) cannot move beyond a certain length.

[0100] The handle (413) is attached to the slide block (411) and can be manually operated to adjust the position of the slide block (411). The handle (413) can be connected to the side opposite the guiding part (4) relative to the slide block (411). For manual operation of the handle (413), the end portion of the handle (413) may have a handle shape or a T-shape.

[0101] As previously explained, in the container loading device of the present invention, the guiding part (4) may be configured as an integrated unit or as a separate unit. In this case, a horizontal moving part (41) may be individually connected to the separated guiding part (4), and the position of the separated guiding part (4) may be individually adjustable through a handle (413).

[0102] Therefore, even if the specifications of the loaded containers (2) are different, the spacing between the guiding parts (4) can be adjusted individually for each layer, so the order or size of the loaded containers (2) may not be limited.

[0103] In addition, the container loading device according to another embodiment of the present invention adopts a sliding structure, so that the area where the individual guiding part (4) contacts the container (2) does not change even if the dimensions of the container (2) differ compared to other folding structures.

[0104] In other folding structures, when the dimensions of the container (2) change, the area of ​​the loading device in contact with the container (2) may change depending on the degree to which the folding structure is unfolded. In cases where the area of ​​the loading device in contact with the container (2) may change in this way, the load distribution of the container (2) may not be properly achieved, and the container (2) may not be properly secured.

[0105] Individual position adjustment of the guiding part (4) via the handle (413) can be manually operated by human power without requiring a separate mechanical device, and the force required for horizontal movement of the guiding part (4) may vary depending on the friction between the roller (412) and the slide block (411).

[0106] In the case of a container loading device according to another embodiment of the present invention, since the handle (413) can be manually operated by human power, the friction between the roller (412) and the slide block (411) may be reduced, and in this case, for safety, several fixing pins (414) to be described later may be installed.

[0107] In the case of other foldable structures, a hydraulic cylinder or motor may be required for operation. If such separate mechanical devices are required, an increase in unit cost is inevitable, and it may be difficult to deal with breakdowns during ship operation. In the case of a container loading device according to another embodiment of the present invention, these problems may not exist because it can be operated by human power.

[0108] The fixing pin (414) is a device that can be inserted between the rollers (412) and the roller (412) to fix the slide block (411) by penetrating it. There may be a hole on one side or top surface of the horizontal moving part (41), and the fixing pin (414) can be applied by penetrating the hole.

[0109] A fixing pin (414) can restrict the movement of a slide block (411) as one of the uneven structures (416) engages with one of the fixing pins (414). The fixing pin (414) may need to be rigid enough to withstand the movement or load of the guiding part (4) and the slide block (411).

[0110] The thickness of the fixing pin (414) may vary depending on the gap between the rollers (412) and the rollers (412), and the length of the fixing pin (414) may be longer than the combined length of the slide block (411) and the upper and lower rollers (412).

[0111] As previously explained, for vertical transport of the hatch cover (5), the guiding part (4) can slide horizontally to expand the space between the guiding parts (4). During the transport process of the hatch cover (5), the guiding part (4) can be fixed by applying a fixing pin (414) to the uneven structure (416) of the slide block (411) so that the guiding part (4) can no longer move horizontally.

[0112] Just as the horizontal movement of the guiding part (4) can be controlled by manpower, the fixing pin (414) can also be operated manually. As shown in FIG. 6, the fixing pin (414) can be positioned to protrude more than the horizontal movement part (41) to facilitate manual operation.

[0113] The fixing pin (414) can be in the form of a flat plate or a cylinder.

[0114] Referring to FIG. 7, multiple fixing pins (414) may be arranged for safety, and permanent fixing pins (415) may be arranged to prevent safety accidents caused by sliding during horizontal movement of the guiding part (4).

[0115] The permanent fixing pin (415) can be positioned opposite the handle (413) in the horizontal moving device and can limit the maximum length that the slide block (411) can move horizontally while restricting the movement of the uneven structure (416).

[0116] Therefore, even if the slide block (411) slides due to mechanical problems such as accidental misoperation through the handle (413) or failure of the roller (412), the accident can be prevented through the permanent fixing pin (415).

[0117] The permanent fixing pin (415) may have a groove so as not to restrict the movement of the slide block (411) excluding the uneven structure (416). The permanent fixing pin (415) may cause the uneven structure (416), which can be placed on the slide block (411), to stop moving horizontally by colliding with or engaging with the permanent fixing pin (415).

[0118] Accordingly, the uneven structure (416) may have a shape that protrudes to the left and right more than the slide block (411), and the shape that protrudes to the left and right is larger than the size of the groove that can be placed on the permanent fixing pin (415), so that it may collide with or interlock with the groove and restrict the movement of the slide block (411).

[0119] Unlike the fixed pin (414) described above, the permanent fixing pin (415) may be difficult to change position and is placed for the purpose of preventing accidents; therefore, it may be formed of a material with better rigidity than the fixed pin (414), or if the same material is used, it may be thicker. In addition, the color or shape may be different to distinguish the permanent fixing pin (415) from the fixed pin (414).

[0120] The fixing pin (414) may also function as a permanent fixing pin (415) depending on its shape and the location where it is applied.

[0121] Below, a container (2) loaded by the above embodiments is described.

[0122] Containers (2) can be loaded into a cargo hold (7) or onto the upper deck (6) or on a hatch cover (5) that serves as a cover for the cargo hold (7). As a securing device for the containers (2), a twist lock connecting the corners of the loaded containers (2) can be used.

[0123] The twist lock can be used for vertical fixing between containers (2), and can also be used to fix the hatch cover (5) and the container (2). The types of twist locks include a manual type in which the lever is manually rotated in both directions to fix, and semi-automatic and full-automatic types.

[0124] Containers (2) can be stacked in eight layers or more on the upper deck (6), and one or two layers stacked beyond the lashing bridge (3) can be connected to a lashing bar (8) for safety, and containers (2) stacked without going beyond the lashing bridge (3) can also be connected to a lashing bar (8). Layers beyond that can be secured by twist locks between the containers (2).

[0125] The present invention is not limited to the embodiments described above, and may include a combination of the above embodiments or a combination of at least one of the above embodiments and known technology as another embodiment.

[0126] Although the present invention has been described in detail through specific embodiments, this is for the purpose of specifically explaining the invention, and the invention is not limited thereto. It will be apparent that modifications or improvements can be made by those skilled in the art within the technical scope of the invention.

[0127] All simple variations or modifications of the present invention fall within the scope of the present invention, and the specific scope of protection of the present invention will be clarified by the appended claims. Explanation of the symbols
