Description

Container securing device and container carrier equipped with same

[0001] The present invention relates to a container securing device and a container carrier equipped with the same.

[0002] Container carriers are increasingly increasing their container loading capacity, and along with this increase in loading capacity, ensuring the stability of loaded containers during operation is attracting attention as an important factor.

[0003] These container carriers load containers into cargo holds arranged forward and backward inside the hull using structures called cell guides. They then install hatch covers on hatch coamings installed at the entrances to the cargo holds on the upper deck of the hull, and then stack containers in multiple tiers on the hatch covers. To prevent containers from tipping over, they are secured to lashing bridges located above the spaces between the cargo holds using various fittings.

[0004] In order to prevent containers loaded on top of the hatch cover from tipping over on a container carrier, it is necessary to secure / unfasten the containers on top of the hatch cover to the lashing bridge using various fittings when unloading containers. This is mostly done manually by workers, requiring excessive work time and safety management, which incurs operating costs for the container carrier.

[0005] In addition, when excessive hull motion occurs due to bad weather during the operation of a container carrier, the hatch cover moves due to the load, the fastening device of the deck or hatch cover is damaged, the fittings of the lashing bridge are broken, or the hatch cover and the hull are relatively displaced, and the lashing system continuously collapses due to imperfect elements of the hatch cover and lashing system, and ultimately, the loaded containers are damaged or lost to the sea.

[0006] The present invention was created to solve the problems of the prior art as described above, and the purpose of the present invention is to provide a container fixing device that can prevent containers that are continuously loaded from the bottom of a cargo hold to the upper part of an upper deck from falling over, and a container carrier equipped with the same.

In this specification, when reference numerals are assigned to components in each drawing, it should be noted that, where possible, identical components are assigned the same reference numerals even if they appear in different drawings. Furthermore, in describing the present invention, if a detailed description of a related known technology is deemed to unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

[0030] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0031]

[0032] FIG. 1 is a longitudinal cross-sectional view of a container carrier according to a first embodiment of the present invention, FIG. 2 is a partial cross-sectional view of a container carrier according to the first embodiment of the present invention, and FIGS. 3 to 8 are drawings for explaining a container carrier according to the first embodiment of the present invention and a container loading assistance device provided thereon.

[0033] As illustrated in FIGS. 1 to 8, a container carrier (1) according to a first embodiment of the present invention can transport containers (C) from a departure point to a destination by loading them in multiple stages inside and outside a hull (10), and as a new concept container carrier without a hatch cover, a container loading auxiliary device (100) for loading and supporting containers (C) can be provided.

[0034] In this embodiment, the container carrier (1) may be a large container carrier that loads a large quantity of containers (C) of 13 or more tiers, including the amount loaded from the bottom of the cargo hold (17) to the upper part of the upper deck (11), but is not limited thereto. In addition, the containers (C) may include 20 ft containers (hereinafter referred to as 'small containers'), 40 ft containers (hereinafter referred to as 'large containers'), or 45 ft or larger containers (hereinafter referred to as 'maximum containers') that are mainly loaded on the container carrier (1). However, according to the ISO standard, containers (C) of various specifications other than the 20 ft or 40 ft mentioned above are used for ships, and there are containers (C) with various specifications. Therefore, it should be noted that the small containers (C) or large containers (C) mentioned below are not used in a meaning limited to 20 ft or 40 ft.

[0035] The hull (10) forms the exterior of the container carrier (1). The hull (10) is surrounded by an upper deck (11), a side plate (12), and a bottom plate (13).

[0036] This hull (10) can be formed with a double-hull structure in which the side plate (12) is formed of a side outer plate (12a) and a side inner plate (12b), and a double-bottom structure in which the bottom plate (13) is formed of a bottom outer plate (13a) and a bottom inner plate (13b).

[0037] Containers (C) can be loaded inside the hull (10). To this end, a plurality of cargo holds (17) are provided inside the hull (10) and are partitioned in the front-rear direction by transverse bulkheads (16). Inside the cargo holds (17), lower cell guides (31) are installed at regular intervals on the side of the transverse bulkhead (16) to guide the loading of containers (C) inside the cargo holds (17).

[0038] In this embodiment, the cargo hold (17) has an open entrance structure, and instead of the existing hatch cover being installed at the entrance, the container loading assistance device (100) to be described later can be configured to be installed at the entrance of the cargo hold (17) or at an arbitrary location inside the cargo hold (17). That is, the entrance of the cargo hold (17) can have a simple structure so that the container loading assistance device (100) can be installed. When the container loading assistance device (100) is installed inside the cargo hold (17), a groove (not shown) can be formed on the upper deck forming the entrance of the cargo hold (17) so that the container loading assistance device (100) can pass through the entrance of the cargo hold (17).

[0039] In addition, when the container loading assistance device (100) of the present embodiment is applied to a container carrier (1) with an existing lashing bridge or a container carrier (1) with a hatch coaming at the entrance to a cargo hold (17), it can be installed on the hatch coaming on the upper deck (11) at the entrance to the cargo hold (17).

[0040] An engine room (R) may be provided at a location adjacent to the stern (15) inside the hull (10). A propulsion engine (not shown) is accommodated within the engine room (R), and the propulsion engine is mechanically or electrically connected to the propeller, and consumes liquefied gas as fuel to rotate the propeller.

[0041] A cabin (A) is provided on the upper deck (11) of the hull (10). The cabin (A) is a living space for the crew, and can be divided into multiple floors in the vertical direction, and a cockpit for controlling navigation can be provided on the uppermost floor.

[0042] An engine casing (I) is provided at the rear of the cabin (A) on the upper deck (11) of the hull (10). The engine casing (I) has a chimney for discharging exhaust generated from the propulsion engine to the outside, and may also form a space for installing an emergency generator or fire extinguishing facilities.

[0043] Containers (C) can be loaded on the upper deck (11) of the hull (10) except for the cabin (A) and engine casing (I). To load containers (C), top bridges (20) are provided on the upper deck (11) spaced apart by a certain distance in the forward and backward directions.

[0044] The top bridge (20) can be installed to extend to the left and right edges of the upper deck (11) between the cargo holds (17), and can be placed at a certain interval from the bow (14) to the stern (15).

[0045] Upper cell guides (32) can be installed at regular intervals on both sides of the top bridge (20). That is, the top bridge (20) of the present embodiment is not a lashing bridge to which a conventional lashing system is applied, but a cell guide system to which an upper cell guide (32) is applied.

[0046] Each of the upper cell guides (32) may be configured integrally with each of the lower cell guides (31) that extend from the top of the top bridge (20) to the upper deck (11) and are installed inside the cargo hold (17). In addition, the upper cell guide (32) is integrally connected with the lower cell guide (31) to form a continuous guide path for containers (C). When the container loading auxiliary device (100) is introduced into the interior of the upper cell guide (32) and lowered using a crane (CR), the container loading auxiliary device (100) may be introduced into the guide path and lowered while being guided by the upper cell guide (32).

[0047] The upper cell guide (32) guides the lifting and lowering of a small container (C) or a large container (C) transported by a crane (CR), and the upper cell guide (32) provided on the top bridge (20) and the lower cell guide (31) installed on the transverse bulkhead (16) are respectively connected, so that continuous loading or unloading operations can be performed without additional operations such as hatch cover mounting or lashing operations when unloading a container (C). The upper cell guide (32) can support the lateral load of the small container (C) or the large container (C) generated by the movement of the hull (10).

[0048] The top bridge (20) of the present embodiment has upper cell guides (32) installed on both sides, so that the upper cell guides (32) can support and fix the containers (C), thereby omitting the existing lashing system (fastening devices such as lashing rods and lashing bars), and can be configured to prevent the containers (C) from falling over before and after the containers (C) are generally loaded in 1 to 4 tier levels, and to secure access and working space for maintenance and monitoring of control units, etc. provided in the reefer container (C), and can solve the problem of the loaded containers (C) being damaged or lost by directly supporting the containers (C) on the upper deck (11) when the container carrier (1) is in operation.

[0049] The top bridge (20) can be composed of a combination of a plurality of vertical members (21) and a plurality of horizontal members (22).

[0050] Among the plurality of vertical members (21), the outer vertical members (21a) arranged in pairs on the upper deck (11) on the left and right sides of the hull (10) can be arranged at intervals corresponding to the width of a small container (C) or a large container (C).

[0051] Among the plurality of vertical members (21), the plurality of intermediate vertical members (21b) arranged between the outer vertical members (21a) can be arranged at intervals corresponding to twice the width of the small container (C) or the large container (C).

[0052] At this time, the upper cell guide (32) can be placed between each of the outer vertical member (21a), the plurality of intermediate vertical members (21b), and the plurality of intermediate vertical members (21b).

[0053] In addition, the top bridge (20) can further improve the safety of the loading container (C) by additionally placing at least one of the lashing eye, lashing ring, lashing plate, plug, and cone, which are container fixing devices of the lashing system, so that the existing lashing system can be additionally applied at the top.

[0054] Although the container carrier (1) according to the first embodiment of the present invention described above has been described as having a top bridge (20) to which a cell guide system is applied, it is not limited thereto, and it goes without saying that a lashing bridge to which a lashing system is applied similarly or identically to the existing one may be installed in some rows or some sections on the left and right sides of one row. In other words, it is to be noted that the container carrier (1) according to the first embodiment of the present invention may have a hybrid bridge in which a top bridge (20) to which the cell guide system of the present invention is applied and a lashing bridge to which a conventional lashing system is applied are mixed.

[0055]

[0056] A container carrier (1) according to the first embodiment of the present invention may be equipped with a container loading assistance device (100).

[0057] A container loading auxiliary device (100) is provided on a container carrier (1) without a hatch cover, and can be configured to be applied to at least one cargo hold (17) to load and support a small container (C) or a large container (C) upward, and can include an upper frame (111), a lower frame (112), a support (113), a protruding member (120), a reinforcing frame (130), a first fitting member (141), and a second fitting member (142). The container loading auxiliary device (100) can form a main body (110) having an overall rectangular box shape by mutually connecting the upper frame (111), the lower frame (112), and the support (113).

[0058] The upper frame (111) may be configured in a square shape with a width corresponding to the width of a small container (C) or a large container (C) and a length corresponding to the length of the large container (C).

[0059] The upper frame (111) may be composed of a pair of first long-axis frames (111a) arranged with a width corresponding to the width of a small container (C) or a large container (C) and having a length corresponding to the length of the large container (C), and a pair of first short-axis frames (111b) connecting the ends of each of the pair of first long-axis frames (111a) and having a width corresponding to the width of the small container (C) or the large container (C).

[0060] The lower frame (112) may be configured in a rectangular shape with a width corresponding to the width of a small container (C) or a large container (C) and a length corresponding to the length of the large container (C).

[0061] The lower frame (112) may be composed of a pair of second long-axis frames (112a) arranged with a width corresponding to the width of a small container (C) or a large container (C) and having a length corresponding to the length of the large container (C), and a pair of second short-axis frames (112b) connecting the ends of each of the pair of second long-axis frames (112a) and having a width corresponding to the width of the small container (C) or the large container (C).

[0062] In the above, each of the pair of second long axis frames (112a) may be configured such that both ends are connected to the lower end of a support (113) to be described later, have a downward slope as they go inward, and are bent so as to be level with each of the pair of first long axis frames (111a) at the middle portion.

[0063] The support (113) may be provided in multiple pieces in the height direction on the upper frame (111) and the lower frame (112), and may be configured to connect each of the square corners of the upper frame (111) and each of the square corners of the lower frame (112).

[0064]

[0065] The protruding member (120) may be configured to protrude outward from the upper and lower frames (111, 112) or the support member (113) so as to be mounted at any position of the cargo hold (17). The protruding member (120) may be configured to protrude outward in the longitudinal direction from the lower end of each of the support members (113) so as to be mounted at the entrance of the cargo hold (17) or at any position inside the cargo hold (17).

[0066] When the protruding member (120) is installed on the upper deck (11) at the entrance of the cargo hold (17), the load of a small container (C) or a large container (C) transmitted through the support (113) can be transmitted to the upper deck (11).

[0067] When the protruding member (120) is installed at an arbitrary position inside the cargo hold (17) using a position adjusting member (not shown), a groove through which the protruding member (120) passes can be formed in the upper deck (11) at the entrance of the cargo hold (17) at the portion where the protruding member (120) is installed. Accordingly, the protruding member (120), after passing through the groove formed in the upper deck (11), is installed on the position adjusting member installed at an arbitrary position of the transverse bulkhead (16) inside the cargo hold (17), and the load of the small container (C) or large container (C) transmitted through the support (113) can be transmitted to the transverse bulkhead (16).

[0068] When the container loading assistance device (100) of the present invention is applied to an existing container carrier having a lashing bridge installed or an existing container carrier having a hatch coaming at the entrance to a cargo hold (17), the protruding member (120) can be installed on the upper hatch coaming of the upper deck (11) at the entrance to the cargo hold (17).

[0069]

[0070] The reinforcing frame (130) connects the middle part in the longitudinal direction of the upper frame (111) and the middle part in the longitudinal direction of the lower frame (112), and can support the load of a small container (C) or a large container (C) loaded on the upper surface of the container loading auxiliary device (100).

[0071] The reinforcing frame (130) may be composed of a first horizontal reinforcing member (not shown) connecting the middle portions of each of a pair of first long axis frames (111a), a second horizontal reinforcing member (not shown) connecting the middle portions of each of a pair of second long axis frames (112a), a first vertical reinforcing member (not shown) connecting one end of the first horizontal reinforcing member and one end of the second horizontal reinforcing member, and a second vertical reinforcing member (not shown) connecting the other end of the first horizontal reinforcing member and the other end of the second horizontal reinforcing member.

[0072]

[0073] The first fitting member (141) is provided at the top of each of the square corners of the upper frame (111) and can be used for fixing when loading a large container (C) or a small container (C), or for lifting when transporting with a crane (CR).

[0074] The second fitting member (142) is provided as a pair at the upper part of the middle portion of the upper frame (111), and can be used for fixing when loading a small container (C), or can be used for lifting together with the first fitting member (141) when transporting with a crane (CR).

[0075] In the above, the first fitting member (141) can be formed at the same height at each of the square corners of the upper frame (111), and the second fitting member (142) can be provided at the upper end of the middle portion of each of the pair of first long axis frames (111a), and can be formed 5 mm to 15 mm higher than the height of the first fitting member (141) so that the two facing small containers (C) do not come into contact with each other even if they tilt inward due to a buckling phenomenon caused by a load when two small containers (C) are placed in the longitudinal direction.

[0076] The container loading assistance device (100) of the present invention is provided with a first fitting member (141) and a second fitting member (142), so that, unlike similar technologies of the past, small containers (C) and large containers (C) can be safely fixed together on the upper surface.

[0077]

[0078] The container loading assistance device (100) may further include a first plate (151), a second plate (152), a watertight member (153), and a reinforcing member (160).

[0079] The first plate (151) can be installed on a one-sided frame formed by one of a pair of first long axis frames (111a), one of a pair of second long axis frames (112a), and a support (113) connecting both ends thereof.

[0080] The second plate (152) can be installed on the other side frame formed by the other one of the pair of first long axis frames (111a), the other one of the pair of second long axis frames (112a), and a support (113) connecting both ends thereof.

[0081] The watertight member (153) can be configured to block water (seawater or rain) from flowing into the cargo hold (17) when the container loading assistance device (100) is installed on the upper deck (11) of the cargo hold (17) entrance and a container (C) is loaded thereon, and can include a first watertight plate (153a), a second watertight plate (153b), and a third watertight plate (153c).

[0082] The first watertight plate (153a) can be installed on the upper frame formed by a pair of first long-axis frames (111a) and a pair of first short-axis frames (111b) forming the upper frame (111), and can block water from flowing into the cargo hold (17) through the upper portion of the container loading auxiliary device (100).

[0083] The second watertight plate (153b) can be installed on the front and rear frames formed by the first short frame (111b), the support (113), and the protruding member (120) of the upper frame (111), and can block water from flowing into the cargo hold (17) through the front and rear portions of the container loading auxiliary device (100). The lower portion of the second watertight plate (153b) protrudes outward in response to the shape of the protruding member (120), and is thus positioned on the upper deck (11) of the entrance to the cargo hold (17).

[0084] The third watertight plate (153c) can be installed at a certain height along the edge of each of the pair of first long axis frames (111a) forming the upper frame (111), and can guide water accumulated on the first watertight plate (153a) to the second watertight plate (153b) forming the side of the container loading assistance device (100), thereby preventing water from flowing into the cargo hold (17).

[0085] The third watertight plate (153c) installed along each edge of a pair of first long axis frames (111a) may have a gap width greater than the width of the small container (C) or the large container (C) or may be formed so that the third watertight plate (153c) is lower than the height of the first fitting member (141) and the second fitting member (142) so as not to be damaged when the small container (C) or the large container (C) is fixed to the first and second fitting members (141, 142).

[0086] When a container loading auxiliary device (100) provided with a watertight member (153) as described above is installed on the upper deck (11) at the entrance of a cargo hold (17) and a container (C) is loaded on top thereof, and water flows down the side wall of the container (C), the water accumulates on the first watertight plate (153a), and the accumulated water does not overflow to the side of the container loading auxiliary device (100) by the third watertight plate (153c) and flows into the interior of the cargo hold (17), but can be drained to the upper deck (11) through the second watertight plate (153b).

[0087]

[0088] The reinforcing member (160) can be installed on at least one of the outer and inner surfaces of each of the first plate (151) and the second plate (152).

[0089] When the reinforcing member (160) is installed on the outer surface of each of the first plate (151) and the second plate (152), it may be composed of an intermediate reinforcing member (161) connected to each of the first long axis frames (111a) and the second long axis frame (112a) so as to face each of the first vertical reinforcing member and the second vertical reinforcing member with each of the first plate (151) and the second plate (152) interposed therebetween, and a first and second reinforcing member (162, 163) arranged between the supports (113) on both sides based on the intermediate reinforcing member (161), but connected to each of the first long axis frames (111a) at the bent portion of each of the second long axis frames (112a).

[0090] In this embodiment, the pair of second long axis frames (112a) have been described as having a folded shape, but it is obvious that they can be formed in a flat shape. That is, the container loading assistance device (100) of this embodiment can be manufactured in the shape of a rectangular box.

[0091] The container loading assistance device (100) of the present invention can secure rigidity capable of supporting the load of a container (C) loaded on top by itself, unlike similar technologies in the related art, by including all or part of a reinforcing frame (130), a first plate (151), a second plate (152), and a reinforcing member (160).

[0092]

[0093] The container loading assistance device (100) may further include a loading member (170) that vertically connects and / or supports the main body (110).

[0094] The stacking member (170) may have a structure that can be converted from a first state in which it is stacked on a transport vehicle or land to a second state in which it is stacked on a container carrier (1).

[0095] The stacking member (170) may be composed of a stacking leg (171) installed on the outer side in the width direction on each side of the support (113), and a third fitting member (172) provided at the lower end of each stacking leg (171) and connected to the first fitting member (141) provided on the main body (110) to be stacked at the top when stacking the main body (110) in multiple stages.

[0096] The stacking legs (171) can be configured so that when the main body (110) is stacked in multiple stages using the first fitting member (141) and the third fitting member (172), a pair of second fitting members (142) provided on the main body (110) stacked at the bottom do not come into contact with the lower frame (112) of the main body (110) stacked at the top.

[0097] That is, the stacking leg (171) may be formed to a length such that, when the container loading auxiliary devices (100) are stacked vertically, the lower part of the container loading auxiliary device (100) stacked on top and the upper part of the container loading auxiliary device (100) stacked on the lower part do not touch each other. This is because there is a possibility of damage due to contact friction when the upper and lower container loading auxiliary devices (100) are in contact and shaken by external environmental factors.

[0098] In addition, the loading member (170) can be formed to have a structure that comes into contact with the hatch coaming (not shown in the drawing symbol) or the lower cell guide (31) of the cargo hold (17) entrance when the container loading assistance device (100) is installed at the cargo hold (17) entrance, and can extend to the lower part of the protruding member (120).

[0099] By configuring the loading member (170) as described above, the container loading auxiliary device (100) can be stably fixedly installed at the entrance of the cargo hold (17), and when the container loading auxiliary device (100) is elevated between the top bridges (20) to install or remove it, it comes into contact with the upper cell guide (32) to guide the elevation stably.

[0100]

[0101] The container loading assistance device (100) configured as described above can be guided by the upper cell guide (32) when being raised and lowered between neighboring tower bridges (20) by a crane (CR).

[0102] In addition, the container loading auxiliary device (100) can be stored by being placed between outer vertical members (21a) facing forward and backward on the upper deck (11) on the left or right side of the hull (10) during container unloading or before container loading, and although not shown, it can be stored by being placed between intermediate vertical members (21b) facing forward and backward, and of course, it can be stored by being placed between two or more vertical members (21) even when two or more container loading auxiliary devices (100) are connected in parallel. In this way, by placing and storing the container loading auxiliary device (100) on the container carrier (1), there is no need for a separate storage area on land, and the efficiency of unloading the container (C) can be improved.

[0103] In the present invention, the container carrier (1) is connected to lower cell guides (31) installed at regular intervals on the side of the transverse bulkhead (16) in the cargo hold (17), and upper cell guides (32) installed on the top bridge (20) corresponding thereto. The ability to continuously load containers (C) from the bottom of the cargo hold (17) to the top of the upper deck (11) may be similar to the open-top of a conventional small container carrier, but the container carrier (1) of the present invention can load containers (C) in bulk in 13 or more stages, including the amount loaded from the bottom of the cargo hold (17) to the top of the upper deck (11), due to the roles of the container loading auxiliary device (100) located in the center of the cell guides (31, 32) and the top bridge (20) and upper cell guide (32) installed on the upper deck (11).

[0104]

[0105] FIGS. 9 to 11 are drawings for explaining a container carrier according to a second embodiment of the present invention, wherein FIG. 9 is a cross-sectional view of a container carrier according to a second embodiment of the present invention, FIG. 10 is a partial side view of a container carrier according to a second embodiment of the present invention, and FIG. 11 is a partial side perspective view of a container carrier according to a second embodiment of the present invention.

[0106] Referring to FIGS. 9 to 11, a container carrier (1) according to a second embodiment of the present invention may have the same or similar overall configuration as the container carrier (1) according to the first embodiment described above, including a container loading auxiliary device (100) and a tower bridge (20), but may differ in that it further includes a container securing device (200) and a first auxiliary structure (AS1) for connecting the container securing device (200) to the hull (10).

[0107] Accordingly, in order to avoid duplication of explanation, the description will focus on the container securing device (200) and the first auxiliary structure (AS1), which are different configurations compared to the container carrier (1) according to the first embodiment described above, and detailed descriptions of other configurations that are the same or similar will be omitted.

[0108] The top bridge (20) is a fixed structure provided on the hull (10) for fixing the container (C), as described in the first embodiment, and can be installed to extend to the left and right edges of the upper deck (11) between the cargo holds (17), and can be arranged in multiple rows in the longitudinal direction of the hull (10).

[0109] Upper cell guides (32) can be installed at regular intervals on both sides of the top bridge (20).

[0110] As described above, the upper cell guide (32) extends from the top of the top bridge (20) to the upper deck (11), is integrally connected to the lower cell guide (31) installed inside the cargo hold (17), and forms a continuous guide path for the container (C). When the container (C) and the container loading auxiliary device (100) are introduced into the upper cell guide (32) and lowered using a crane (CR), the container (C) and the container loading auxiliary device (100) can be guided by the upper cell guide (32) and be introduced into the guide path and lowered.

[0111] The container loading assistance device (100) is provided on a container carrier (1) without a hatch cover, as described in the first embodiment, and can be configured to be applied to at least one cargo hold (17) to load and support a container (C) upward, and can include an upper frame (111), a lower frame (112), a support (113), a protruding member (120), a reinforcing frame (130), a first fitting member (141), and a second fitting member (142). The container loading assistance device (100) can form a body (110) having an overall rectangular box shape by mutually connecting the upper frame (111), the lower frame (112), and the support (113), and can further include a first plate (151), a second plate (152), a watertight member (153), a reinforcing member (160), and a stacking member (170).

[0112] Containers (C) can be loaded in multiple stages on the upper part of the container loading auxiliary device (100).

[0113] A plurality of containers (C) loaded on top of a container loading auxiliary device (100) can be fixed to each other by using fitting members such as twist locks (not shown) to be loaded vertically.

[0114] The twist lock may be a fitting member that interconnects a corner casting (C11) provided at a lower edge of an upper container (C) and a corner casting (C11) provided at an upper edge of a lower container (C).

[0115] Corner casting (C11) is generally manufactured in the shape of a square box, with four corners installed on the upper surface of the container (C) and four corners installed on the lower surface, and holes can be provided on the upper surface and side for use as hooks for transporting the container (C), for use as a tie for twist locking the upper and lower containers (C) during loading, and for use as a lashing for fixing the loaded container (C).

[0116] The upper container (C) and the lower container (C), which are loaded vertically at a position higher than the top of the top bridge (20), can be connected and fixed to the top bridge (20) using a lashing member (340) provided on the container carrier (1) of the third embodiment described later in addition to a twist lock, thereby further preventing the containers (C) from falling over.

[0117] In the case where a lashing member (340) is applied to a container carrier (1) of the second embodiment, as in the container carrier (1) of the third embodiment described below, at least one of a lashing eye, a lashing ring, a lashing plate, a plug, and a cone may be additionally installed on the top bridge (20) so that upper and lower containers (C) loaded vertically at a position higher than the top of the top bridge (20) can be connected to the top bridge (20) using the lashing member (340).

[0118] However, when applying a lashing member (340) to a container carrier (1) of the second embodiment, the cost and installation work required for using the lashing member (340) may be excessive, so, as described above in the first embodiment, the upper cell guide (32) supports and fixes the container (C) loaded on the upper portion of the container loading auxiliary device (100), so it goes without saying that the lashing member (340) can be omitted in the container carrier (1) of the second embodiment.

[0119] The container carrier (1) of the second embodiment can prevent the container (C) from overturning by supporting and fixing the loaded container (C) by the upper cell guide (32) provided on both sides of the top bridge (20), but there is a limit to preventing the container (C) from overturning when the container carrier (1) shakes violently due to bad weather such as yellow sea voyage.

[0120] Accordingly, the container carrier (1) according to the second embodiment may further include a container securing device (200) and a first auxiliary structure (AS1) for connecting the container securing device (200) to the top bridge (20) so as to effectively prevent the container (C) from overturning.

[0121] A container fixing device (200) can be configured to fix a container (C) loaded vertically at a position higher than the top of the tower bridge (20) by connecting it to the tower bridge (20). The detailed configuration of this container fixing device (200) will be described later with reference to FIGS. 15 to 20.

[0122] The container securing device (200) can be connected to the top bridge (20) at positions corresponding to the front left and right sides and the rear left and right sides of the container (C) to secure the upper and lower containers (C). That is, four container securing devices (200) can be installed in one container (C).

[0123] As shown in Fig. 9, the container fixing device (200) can be provided to securely fasten upper and lower containers (C) that are loaded vertically at a position higher than the top of the top bridge (20) among the outermost containers (C) that are loaded in multiple layers by being supported by a stool structure (320) installed on the upper side of the upper deck (11) on the left and right sides of the hull (10).

[0124] In this embodiment, the container fixing device (200) is described as fixing the outermost container (C), but it is not limited thereto, and it is of course possible to fix upper and lower containers (C) loaded vertically at a position higher than the top of the top bridge (20) on the inside of the outermost container (C).

[0125] The container fixing device (200) can be installed so that the lower end is fixedly connected to the first auxiliary structure (AS1) installed on the top bridge (20) and extends upwardly in the length direction of the container (C) in order to fix the upper container (C) and the lower container (C) that are loaded vertically and prevent the container (C) from falling over, and the upper end can be installed so as to be connected to at least one of the holes of the corner casting (C11) provided on the lower edge of the upper container (C) and the holes of the corner casting (C11) provided on the upper surface of the lower container (C).

[0126] The container fixing device (200) can extend in a nearly vertical upward incline from the first auxiliary structure (AS1) provided on the upper part of the top bridge (20) to the corner casting (C11) provided at the corner of the container (C), as shown in FIGS. 10 and 11.

[0127] In this way, the container fixing device (200) is installed so as to have an upward inclination close to vertical with respect to the container (C) while connected to the upper and lower containers (C), thereby generating tension toward the hull (10), thereby not only increasing the binding strength between the upper and lower containers (C), but also restraining the shaking of a plurality of containers (C) loaded between the lower top bridges (20) of the upper and lower containers (C), thereby further preventing the containers (C) from overturning.

[0128] As illustrated in FIG. 11, the container fixing device (200) can be installed so as to have an upward inclination in the longitudinal direction of the container (C) by being simultaneously connected to holes (not shown in the drawing symbol) provided on both sides of the container (C) in each of the corner castings (C11) provided on the lower edge of the upper container (C) and the corner castings (C11) provided on the upper edge of the lower container (C).

[0129] At this time, the container fixing device (200) may be installed so that the first connecting portion (211b) of the head member (210) is connected to the corner casting (C11) of the upper container (C), and the second connecting portion (211c) of the head member (210) is connected to the corner casting (C11) of the lower container (C), and two of them may be installed on each of the front and rear sides of the container (C) so as to be parallel in the width direction of the container (C).

[0130] In this case, when the container fixing device (200) is connected to the upper and lower containers (C) at the same time, the upper and lower containers (C) can be mutually fixed by the container fixing device (200), so the installation of a twist lock that is installed on the corner casting (C11) of the upper container (C) and the corner casting (C11) of the lower container (C) to fix the upper and lower containers (C) can be omitted.

[0131] In addition, the container fixing device (200), although not shown, may be installed so as to have an upward inclination in the longitudinal direction of the container (C) by being connected to one of the holes provided on either side of the container (C) in each of the corner casting (C11) provided on the lower edge of the upper container (C) and the corner casting (C11) provided on the upper edge of the lower container (C).

[0132] At this time, the container fixing device (200) may be connected such that the first connecting portion (211b) of the head member (210) is connected to the corner casting (C11) of the upper container (C) or the corner casting (C11) of the lower container (C), or the second connecting portion (211c) of the head member (210) is connected to the corner casting (C11) of the upper container (C) or the corner casting (C11) of the lower container (C), and two of them may be installed parallel to each other in the width direction of the container (C) at the front and rear sides of the container (C).

[0133] In this way, when the container fixing device (200) is connected to one of the upper and lower containers (C), since the upper and lower containers (C) cannot be fastened together with the container fixing device (200), the upper and lower containers (C) can be fastened together by installing a twist lock on the corner casting (C11) of the upper container and the corner casting (C11) of the lower container.

[0134] In addition, the container fixing device (200), although not shown, may be installed so as to have an upward inclination in the longitudinal direction of the container (C) by being connected to at least one hole among the holes provided toward the front and rear of the container (C) in each of the corner casting (C11) provided at the lower edge of the upper container (C) and the corner casting (C11) provided at the upper edge of the lower container (C).

[0135] At this time, the container fixing device (200) may be connected such that the first connecting portion (211b) of the head member (210) is connected to at least one corner casting (C11) among the corner casting (C11) of the upper container (C) and the corner casting (C11) of the lower container (C), or the second connecting portion (211c) of the head member (210) is connected to at least one corner casting (C11) among the corner casting (C11) of the upper container (C) and the corner casting (C11) of the lower container (C), and two of them may be installed parallel to each other in the width direction of the container (C) at the front and rear sides of the container (C).

[0136] In addition, the container fixing device (200), although not shown, may be installed so as to have an upward slope in the width direction of the container (C) by being connected to at least one hole among the holes provided toward the front and rear sides of the container (C) in each of the corner casting (C11) provided at the lower edge of the upper container (C) and the corner casting (C11) provided at the upper edge of the lower container (C), respectively. In this case, the container fixing device (200) is installed so that two of them intersect in a diagonal direction at each of the front and rear sides of the container (C) so as to fix the upper container (C) and the lower container (C).

[0137] At this time, the container fixing device (200) may be installed so that the first connecting portion (211b) of the head member (210) is connected to at least one corner casting (C11) among the corner casting (C11) of the upper container (C) and the corner casting (C11) of the lower container (C), or the second connecting portion (211c) of the head member (210) is connected to at least one corner casting (C11) among the corner casting (C11) of the upper container (C) and the corner casting (C11) of the lower container (C), and two of them may be installed so that they intersect in the width direction of the container (C) at each of the front and rear sides of the container (C).

[0138]

[0139] The first auxiliary structure (AS1) can be formed to protrude above the top bridge (20).

[0140] The first auxiliary structure (AS1) may be configured to connect the container securing device (200) to the top bridge (20).

[0141] The first auxiliary structure (AS1) can be installed on the top of the top bridge (20) at positions corresponding to the front and rear left sides of the container (C) and the front and rear right sides of the container (C), respectively, so that container fixing devices (200) can be installed on the front and rear left sides and the rear left and right sides of the container (C), as shown in FIGS. 10 and 11.

[0142] The first auxiliary structure (AS1) may be installed at an interval equal to or similar to the width of the container (C) so that the container fixing device (200) can be installed at an upward incline in the longitudinal direction of the container (C) by being connected to at least one of the holes provided on both sides of the container (C) in each of the corner castings (C11) provided on the lower edge of the upper container (C) and the corner castings (C11) provided on the upper edge of the lower container (C).

[0143] The first auxiliary structure (AS1), as illustrated in FIG. 11, may be provided in a separate form so that one container fixing device (200) connecting the rear of a container (C) positioned forward relative to the top bridge (20) and another container fixing device (200) connecting the front of a container (C) positioned rearward relative to the top bridge (20) can be individually connected.

[0144] If the first auxiliary structure (AS1) is detachable, a fixing means (not shown in the drawing) for fixing a connecting portion (232a) provided to a container fixing device (200) may be provided on the upper side of the first auxiliary structure (AS1).

[0145] In addition, the first auxiliary structure (AS1) can be provided as an integral unit so as to be able to simultaneously connect one container securing device (200) and another container securing device (200), as will be described later with reference to FIG. 14.

[0146]

[0147] The container carrier (1) according to the second embodiment configured as described above, in addition to fixing the container (C) to the hull (10) using the upper cell guide (32), fixes at least the outermost container (C) using the container fixing device (200), thereby strengthening the fixing force of the outermost container (C), so that even if the container carrier (1) shakes violently due to bad weather such as yellow sea voyage and the container (C) loaded on the inside of the outermost container (C) shakes, the outermost container (C) acts as a fixing structure on the left and right sides of the hull (10), thereby more efficiently preventing the container (C) from overturning.

[0148]

[0149] FIGS. 12 to 14 are drawings for explaining a container carrier according to a third embodiment of the present invention, wherein FIG. 12 is a cross-sectional view of a container carrier according to a third embodiment of the present invention, FIG. 13 is a partial side view of a container carrier according to a third embodiment of the present invention, and FIG. 14 is a partial side perspective view of a container carrier according to a third embodiment of the present invention.

[0150] Referring to FIGS. 12 to 14, a container carrier (1) according to a third embodiment of the present invention may have an overall configuration that is the same or similar to that of the container carrier (1) according to the first embodiment described above, but may differ in that the container loading assistance device (100) and the top bridge (20) of the first embodiment are omitted and a hatch cover (310) and a lashing bridge (330) are installed.

[0151] A container carrier (1) according to a third embodiment of the present invention is a container carrier that loads containers (C) in multiple stages inside and outside the hull (10) and transports them from a departure point to a destination, and may be equipped with a hatch cover (310) for loading and supporting containers (C) and a lashing bridge (330) for fixing containers (C) loaded on top of the hatch cover (310) and for maintenance of the containers (C).

[0152] The hull (10) forms the exterior of the container carrier (1). The hull (10) is surrounded by an upper deck (11), a side plate (12), and a bottom plate (13).

[0153] This hull (10) can be formed with a double-hull structure in which the side plate (12) is formed of a side outer plate (12a) and a side inner plate (12b), and a double-bottom structure in which the bottom plate (13) is formed of a bottom outer plate (13a) and a bottom inner plate (13b).

[0154] Containers (C) can be loaded inside the hull (10). For this purpose, a number of cargo holds (17) are provided inside the hull (10) and are partitioned in the front-rear direction by transverse bulkheads (16).

[0155] Inside the cargo hold (17), lower cell guides (31) are installed at regular intervals on the side of the transverse bulkhead (16) to guide the loading of containers (C) inside the cargo hold (17).

[0156] The cargo hold (17) can have a hatch cover (310) installed at the entrance.

[0157] Containers (C) can be loaded in multiple stages on the upper part of the hatch cover (310).

[0158] The lashing bridge (330) is a fixed structure provided on the hull (10) for fixing a container (C), and can be installed to extend to the left and right edges of the upper deck (11) between the cargo holds (17), and can be arranged in multiple rows in the longitudinal direction of the hull (10).

[0159] A plurality of containers (C) loaded on the upper part of the hatch cover (310) can be fixed to each other by using fitting members such as twist locks (not shown) to be connected to each other.

[0160] The twist lock may be a fitting member that interconnects a corner casting (C11) provided at a lower edge of an upper container (C) and a corner casting (C11) provided at an upper edge of a lower container (C).

[0161] Corner casting (C11) is generally manufactured in the shape of a square box, with four corners installed on the upper surface of the container (C) and four corners installed on the lower surface, and holes can be provided on the upper surface and side for use as hooks for transporting the container (C), for use as a tie for twist locking the upper and lower containers (C) during loading, and for use as a lashing for fixing the loaded container (C).

[0162] The upper container (C) and the lower container (C), which are loaded vertically at a position higher than the top of the lashing bridge (330), are connected and fixed to the lashing bridge (330) using a lashing member (340) in addition to a twist lock to prevent the container (C) from falling over.

[0163] The lashing member (340) may be a conventional lashing bar that connects and fixes upper and lower containers (C) loaded vertically at a position higher than the upper end of the lashing bridge (330) to the lashing bridge (330), and may be connected to at least one of a lashing eye, a lashing ring, a lashing plate, a plug, and a cone installed on the lashing bridge (330).

[0164] The lashing member (340) can be extended in the first direction from the lashing bridge (330) and connected to the container (C).

[0165] As illustrated in FIG. 12, the lashing member (340) may be installed so as to have an upward slope in the width direction of the container (C) by being fixedly connected to a structure such as an existing lashing eye or a first auxiliary structure (AS1) installed on a lashing bridge (330) at the lower end so as to prevent the container (C) from overturning by fixing the upper container (C) and the lower container (C), and may be installed so as to have an upward slope in the width direction of the container (C) by being connected to one of the holes provided in the front and rear sides of the container (C) at the upper end of each of the corner castings (C11) provided at the lower edge of the upper container (C) and the corner castings (C11) provided at the upper edge of the lower container (C). In this case, the lashing members (340) are installed so as to diagonally intersect in four pieces, two each at the front and rear sides of the container (C), so as to fix the upper container (C) and the lower container (C).

[0166] This lashing member (340) is a conventional lashing bar that is generally widely applied and is installed to prevent the container (C) from overturning, but has limitations in preventing the container (C) from overturning when the container carrier (1) shakes violently due to bad weather such as yellow sea voyage.

[0167] Accordingly, the container carrier (1) according to the third embodiment may further include a container securing device (200) and a second auxiliary structure (AS2) for connecting the container securing device (200) to the lashing bridge (330) so as to effectively prevent the container (C) from overturning.

[0168] The container securing device (200) can be extended in the second direction from the lashing bridge (330) and connected to the container (C).

[0169] The container securing device (200) can be configured to secure a container (C) loaded vertically at a position higher than the top of the lashing bridge (330) by connecting it to the lashing bridge (330). The detailed configuration of this container securing device (200) will be described later with reference to FIGS. 15 to 20.

[0170] The container securing device (200) can be connected to the lashing bridge (330) at positions corresponding to the front left and right sides and the rear left and right sides of the container (C) to secure the upper and lower containers (C). That is, four container securing devices (200) can be installed in one container (C).

[0171] As shown in Fig. 12, the container fixing device (200) can be provided to secure upper and lower containers (C) that are loaded vertically at a position higher than the top of the lashing bridge (330) among the outermost containers (C) that are loaded in multiple layers by being supported by a stool structure (320) installed on the upper side of the upper deck (11) on the left and right sides of the hull (10).

[0172] In this embodiment, the container fixing device (200) is described as fixing the outermost container (C), but it is not limited thereto, and it is of course possible to fix upper and lower containers (C) loaded vertically at a position higher than the top of the lashing bridge (330) on the inside of the outermost container (C).

[0173] The container fixing device (200) can be installed so that the lower end is fixedly connected to a second auxiliary structure (AS2) installed on a lashing bridge (330) to prevent the container (C) from falling over by fixing the upper container (C) and the lower container (C) that are loaded vertically, and extends upwardly in a longitudinal direction of the container (C), and the upper end is connected to at least one of a corner casting (C11) provided on the lower edge of the upper container (C) and a corner casting (C11) provided on the upper surface of the lower container (C).

[0174] The container securing device (200) can extend in a nearly vertical upward incline from the second auxiliary structure (AS2) provided on the upper part of the lashing bridge (330) to the corner casting (C11) provided at the corner of the container (C), as shown in FIGS. 13 and 14.

[0175] In this way, the container fixing device (200) is installed so as to have a nearly vertical inclination with respect to the container (C) while connected to the upper and lower containers (C), thereby generating tension toward the hull (10), thereby not only increasing the binding strength between the upper and lower containers (C), but also restraining the shaking of a plurality of containers (C) loaded between the lower lashing bridges (330) of the upper and lower containers (C), thereby further preventing the containers (C) from overturning.

[0176] As illustrated in FIG. 14, the container fixing device (200) can be installed so as to have an upward inclination in the longitudinal direction of the container (C) by being simultaneously connected to holes (not shown in the drawing symbol) provided on both sides of the container (C) in each of the corner castings (C11) provided on the lower edge of the upper container (C) and the corner castings (C11) provided on the upper edge of the lower container (C).

[0177] At this time, the container fixing device (200) may be installed so that the first connecting portion (211b) of the head member (210) is connected to the corner casting (C11) of the upper container (C), and the second connecting portion (211c) of the head member (210) is connected to the corner casting (C11) of the lower container (C), and two of them may be installed on each of the front and rear sides of the container (C) so as to be parallel in the width direction of the container (C).

[0178] In this case, when the container fixing device (200) is connected to the upper and lower containers (C) at the same time, the upper and lower containers (C) can be mutually fixed by the container fixing device (200), so the installation of a twist lock that is installed on the corner casting (C11) of the upper container (C) and the corner casting (C11) of the lower container (C) to fix the upper and lower containers (C) can be omitted.

[0179] In addition, the container fixing device (200), although not shown, may be installed so as to have an upward inclination in the longitudinal direction of the container (C) by being connected to one of the holes provided on either side of the container (C) in each of the corner casting (C11) provided on the lower edge of the upper container (C) and the corner casting (C11) provided on the upper edge of the lower container (C).

[0180] At this time, the container fixing device (200) may be connected such that the first connecting portion (211b) of the head member (210) is connected to the corner casting (C11) of the upper container (C) or the corner casting (C11) of the lower container (C), or the second connecting portion (211c) of the head member (210) is connected to the corner casting (C11) of the upper container (C) or the corner casting (C11) of the lower container (C), and two of them may be installed parallel to each other in the width direction of the container (C) at the front and rear sides of the container (C).

[0181] In this way, when the container fixing device (200) is connected to one of the upper and lower containers (C), since the upper and lower containers (C) cannot be fastened together with the container fixing device (200), the upper and lower containers (C) can be fastened together by installing a twist lock on the corner casting (C11) of the upper container and the corner casting (C11) of the lower container.

[0182] In addition, the container fixing device (200), although not shown, may be installed so as to have an upward inclination in the longitudinal direction of the container (C) by being connected to at least one hole among the holes provided toward the front and rear of the container (C) in each of the corner casting (C11) provided at the lower edge of the upper container (C) and the corner casting (C11) provided at the upper edge of the lower container (C).

[0183] At this time, the container fixing device (200) may be connected such that the first connecting portion (211b) of the head member (210) is connected to at least one corner casting (C11) among the corner casting (C11) of the upper container (C) and the corner casting (C11) of the lower container (C), or the second connecting portion (211c) of the head member (210) is connected to at least one corner casting (C11) among the corner casting (C11) of the upper container (C) and the corner casting (C11) of the lower container (C), and two of them may be installed parallel to each other in the width direction of the container (C) at the front and rear sides of the container (C).

[0184] In the above, when the container fixing device (200) is simultaneously connected to the corner castings (C11) of the upper and lower containers (C) so as to have an upward slope in the longitudinal direction of the container (C), the installation of the lashing member (340) can be omitted, and when the container fixing device (200) is connected to one of the corner castings (C11) of the upper and lower containers (C) so as to have an upward slope in the longitudinal direction of the container (C), the lashing member (340) can be installed to the corner casting (C11) to which the container fixing device (200) is not connected so as to have an upward slope in the width direction of the container (C).

[0185] In addition, the container fixing device (200), although not shown, may be installed so as to have an upward inclination in the width direction of the container (C) by being connected to at least one hole among the holes provided toward the front and rear of the container (C) in each of the corner casting (C11) provided at the lower edge of the upper container (C) and the corner casting (C11) provided at the upper edge of the lower container (C).

[0186] At this time, the container fixing device (200) may be installed so that the first connecting portion (211b) of the head member (210) is connected to at least one corner casting (C11) among the corner casting (C11) of the upper container (C) and the corner casting (C11) of the lower container (C), or the second connecting portion (211c) of the head member (210) is connected to at least one corner casting (C11) among the corner casting (C11) of the upper container (C) and the corner casting (C11) of the lower container (C), and two of them may be installed so that they intersect in the width direction of the container (C) at each of the front and rear sides of the container (C).

[0187] In the above, when the container fixing device (200) is simultaneously connected to the corner castings (C11) of the upper and lower containers (C) so as to have an upward slope in the width direction of the container (C), the installation of the lashing member (340) can be omitted, and when the container fixing device (200) is connected to one of the corner castings (C11) of the upper and lower containers (C) so as to have an upward slope in the width direction of the container (C), the lashing member (340) can be installed to the corner casting (C11) to which the container fixing device (200) is not connected so as to have an upward slope in the width direction of the container (C).

[0188]

[0189] The second auxiliary structure (AS2) may be formed to protrude from the upper portion of the lashing bridge (330).

[0190] The second auxiliary structure (AS2) may be configured to connect the container securing device (200) to the lashing bridge (330).

[0191] Additionally, the second auxiliary structure (AS2) can be configured to connect the lashing member (340) to the lashing bridge (330) together with the container securing device (200).

[0192] The second auxiliary structure (AS2) can be installed on the upper part of the lashing bridge (330) at positions corresponding to the front and rear left sides of the container (C) and the front and rear right sides of the container (C), respectively, so that container fixing devices (200) can be installed on the front and rear left sides and the rear left and right sides of the container (C), as shown in FIGS. 13 and 14.

[0193] The second auxiliary structure (AS2) may be installed at an interval equal to or similar to the width of the container (C) so that the container fixing device (200) can be installed at an upward incline in the longitudinal direction of the container (C) by being connected to at least one of the holes provided on both sides of the container (C) in each of the corner castings (C11) provided on the lower edge of the upper container (C) and the corner castings (C11) provided on the upper edge of the lower container (C).

[0194] The second auxiliary structure (AS2), as illustrated in FIG. 14, can be provided as an integral unit so as to simultaneously connect one container securing device (200) connecting the rear of a container (C) positioned forward relative to a lashing bridge (330) and another container securing device (200) connecting the front of a container (C) positioned rearward relative to a lashing bridge (330).

[0199]

[0200] The container carrier (1) according to the third embodiment configured as described above, in addition to fixing the container (C) to the hull (10) in a general manner using a lashing member (340), fixes at least the outermost container (C) using a container fixing device (200), thereby strengthening the fixing force of the outermost container (C), so that even if the container carrier (1) shakes violently due to bad weather such as yellow sea voyage and the container (C) loaded on the inside of the outermost container (C) shakes, the outermost container (C) acts as a fixing structure on the left and right sides of the hull (10), thereby more efficiently preventing the container (C) from overturning.

[0201]

[0202] Hereinafter, a container fixing device (200) provided on a container carrier (1) according to the second and third embodiments of the present invention described above will be described with reference to FIGS. 15 to 21.

[0204] Referring to FIGS. 15 to 21, the container fixing device (200) of the present invention is a device for fixing a container (C) loaded on the upper deck (11) of a container carrier (1), and as described in the second and third embodiments, the container (C) can be fixed by connecting to a top bridge (20) or a lashing bridge (330), which is a fixing structure provided on a hull (10) for fixing the container (C).

[0205] Such a container fixing device (200) may include a head member (210), a load member (220), and a fixing member (230).

[0206] The head member (210) can be connected to a container (C) loaded on the upper deck (11) of a container carrier (1).

[0207] The head member (210) can connect the upper container (C) and the lower container (C) that are loaded vertically, and can include a connecting portion (211) and a joint (212).

[0208] The connecting portion (211) forms a certain angle from the load member (220) and extends toward the upper container (C) and the lower container (C) that are loaded vertically, thereby connecting the upper container (C) and the lower container (C) to each other.

[0209] This joint (211) may include a body (211a), a first joint (211b), and a second joint (211c).

[0210] The body part (211a) may have an overall triangular shape.

[0211] The body portion (211a) can be configured such that the first vertex is rotatably connected to the joint (212) in the first direction, as illustrated in FIG. 16. That is, the body portion (211a) can be rotated equiangularly about the longitudinal direction of the load member (220) as an axis, and no specific directionality is required when connecting the first coupling portion (211b) and the second coupling portion (211c) to the container (C).

[0212] The first connecting portion (211b) may be provided at a second vertex spaced a certain distance from the first vertex of the body portion (211a).

[0213] The second connecting portion (211c) may be provided at a third vertex spaced a certain distance from the first vertex of the body portion (211a).

[0214] The first coupling portion (211b) and the second coupling portion (211c) can be configured to be inserted into and fastened to a hole (not shown in the drawing symbol) provided in the corner casting (C11) of the container (C), as illustrated in FIG. 17.

[0215] That is, the distance between the first coupling portion (211b) and the second coupling portion (211c) may be the same as the distance between the hole of the corner casting (C11) provided at the lower edge of the upper container (C) and the hole of the corner casting (C11) provided at the upper edge of the lower container (C) when the containers (C) are loaded in the upper and lower portions.

[0216] The joint (212) can rotatably connect between the connecting portion (211) and the load member (220). The joint (212) can apply a 2-knuckle joint to minimize the moment component due to the load applied to the head member (210).

[0217] The joint (212) can be rotatably connected to the connecting portion (211) in a first direction, and can be rotatably connected to the second fastening hole (223a) provided in the second fastening portion (223) of the load member (220) in a second direction. Here, the first direction may be a direction of rotation left and right based on the longitudinal direction of the load member (220), and the second direction may be a direction of rotation back and forth based on the longitudinal direction of the load member (220).

[0218] The head member (210) configured as described above can be selectively inserted into the holes of the corner casting (C11) provided at the lower edge of the upper container (C) and the corner casting (C11) provided at the upper edge of the lower container (C) by connecting the body part (211a) to the joint (212) so as to be equiangularly rotatable in the first direction, respectively, so that the first coupling part (211b) and the second fastening part (223) can be selectively inserted into the holes of the corner casting (C11) provided at the lower edge of the upper container (C) and the corner casting (C11) provided at the upper edge of the lower container (C). As a result, the head member (210) can be simultaneously connected to the corner casting (C11) of the upper container (C) and the corner casting (C11) of the lower container (C), or can be connected to either the corner casting (C11) of the upper container (C) or the corner casting (C11) of the lower container (C).

[0219]

[0220] The load member (220) may be configured to connect between the head member (210) and the fixed member (230), and may include an extension portion (221) that extends long in one direction, a first fastening portion (222) provided on one side of the extension portion (221), and a second fastening portion (223) provided on the other side of the extension portion (221).

[0221] The first fastening portion (222) and the second fastening portion (223) may be provided on both sides of the extension portion (221) in the same or similar shape as illustrated in FIG. 18, and may be formed to have an area larger than the area of ​​the extension portion (221).

[0222] The extension portion (221) may be provided with an overall equal cross-sectional area, and the first fastening portion (222) and the second fastening portion (223) may be provided with a cross-sectional area that increases as they go outward from the extension portion (221).

[0223] A first fastening hole (222a) is provided in the first fastening portion (222) so that a load holder (231) can be fastened by a holder bearing (231a).

[0224] That is, the load member (220) can be connected to the fixed member (230) by the first fastening member (222).

[0225] A second fastening hole (223a) is provided in the second fastening portion (223) so that it can be rotatably connected to the joint (212).

[0226] That is, the load member (220) can be connected to the head member (210) by the second fastening member (223).

[0227] The load member (220) configured in this manner may have a rectangular cross-sectional shape, as illustrated in FIG. 19, and may include a core (224) and an outer layer (225).

[0228] The core (224) can be formed to be long in one direction.

[0229] The core (224) may be formed of steel or a steel fusion material.

[0230] The core (224) may be a component that maintains a gap with the outer layer (225) and increases the convenience of manufacturing.

[0231] The core (224) may have the same cross-sectional area throughout the extension (221), and may have a cross-sectional area that increases as it goes outward from the extension (221) in the first fastening portion (222) and the second fastening portion (223).

[0232] The outer layer (225) may be arranged to surround the outer side of the core (224).

[0233] The outer layer (225) can be provided on the outer side of the core (224), for example, on both sides.

[0234] In this embodiment, the outer layer (225) is described as being provided on both sides of the core (224), but it is of course possible to provide it so as to cover the entire surface including the front and back.

[0235] The outer layer (225) may be formed of a composite material, for example, carbon fiber reinforced plastic (CFRP).

[0236] The outer layer (225) may be a core component that receives the main tensile force from the load member (220).

[0237] Additionally, the load member (220) may further include a cover (226), as illustrated in FIG. 19.

[0238] The cover (226) may be arranged to entirely surround the core (224) and the outer layer (225).

[0239] The cover (226) may be a component that is overlaid to protect the core (224) and the outer layer (225) from the external environment.

[0240] Additionally, the load member (220) may further include a strap (227), as illustrated in FIG. 18.

[0241] The strap (227) may be provided at the boundary between the extension portion (221) and the first fastening portion (222) and the boundary between the extension portion (221) and the second fastening portion (223). That is, the strap (227) may be provided at the boundary where the cross-sectional area of ​​the core (224) changes.

[0242] The strap (227) can be arranged to surround the outer layer (225) at the boundary where the cross-sectional area of ​​the core (224) changes, as shown in FIG. 18.

[0243] Additionally, the strap (227) may be arranged to surround the cover (226) at the boundary portion where the cross-sectional area of ​​the core (224) changes when the cover (226) is formed, as illustrated in FIG. 19.

[0244] These straps (227) prevent the outer layer (225) from being separated from the core (224) or the cover (226) from being separated from the outer layer (225) by compressing the portion where the cross-sectional area changes when tensile force is applied to the load member (220).

[0245]

[0246] The fixed member (230) can be configured to be connected to the hull (10) of the container carrier (1).

[0247] The fixed member (230) may include a load holder (231), a tensioner (232), and a retainer (233).

[0248] The load holder (231) can be configured to accommodate the load member (220).

[0249] The load holder (231) can have an internal structure, as shown in Fig. 20, in which a plurality of spaces in which a bearing (231a) for the holder is fixedly installed can be provided so that the overall length of the container fixing device (200) can be adjusted.

[0250] As shown in Fig. 20, when the holder bearing (231a) coupled to the first fastening hole (222a) provided in the first fastening portion (222) of the load member (220) is located on the inside of the load holder (231), the overall length of the container fixing device (200) becomes the shortest as the load member (220) enters deep into the inside of the load holder (231), and the overall length of the container fixing device (200) becomes longer as the holder bearing (231a) is located on the outside of the load holder (231).

[0251] The tensioner (232) is coupled to a load holder (231) connected to a load member (220), and can be configured to adjust the tension of the load member (220), and can include a connecting portion (232a) and a tightening portion (232b).

[0252] The connecting portion (232a) may be configured such that one end thereof is connected to the hull (10). Here, the hull (10) to which one end of the connecting portion (232a) is connected may be the first auxiliary structure (AS1) provided on the upper portion of the tower bridge (20) described above in the second embodiment, or the second auxiliary structure (AS2) provided on the upper portion of the lashing bridge (330) described above in the third embodiment.

[0253] The other end of the connecting portion (232a) may be configured to extend a certain length from one end and to allow the tightening portion (232b) to be screw-connected.

[0254] The tightening member (232b) is screw-connected to the other end of the connecting member (232a) and can adjust the tension of the load member (220) by rotation.

[0255] The maintenance unit (233) can be provided between the tightening unit (232b) and the load holder (231).

[0256] The maintenance unit (233) can be configured to push the load holder (231) in the opposite direction of the load member (220) while the tension of the load member (220) is adjusted by the tightening unit (232b), thereby maintaining the tension of the load member (220).

[0257] The maintenance member (233) is a part having a certain rigidity and can prevent the head member (210) from being detached while maintaining the tension of the load member (220) until the maximum capacity of the container fixing device (200) is exerted.

[0258]

[0259] The container fixing device (200) configured as described above has a weight that is difficult for a worker to lift.

[0260] Accordingly, the worker can adjust the installation position of the container fixing device (200) using the jig (400), as shown in FIG. 21.

[0261] The jig (400) can be made of a material such as a rod or wire.

[0262] The end of the jig (400) can be configured to be detachable from the load member (220).

[0263] The work process for connecting the container fixing device (200) to the corner casting (C11) of the container (C) is as follows.

[0264] First, with the fixed member (230) separated, the end of the jig (400) is connected to the upper end of the load member (220) on which the head member (210) is mounted, and while the worker holds the lower end of the load member (220) with one hand and the jig (400) with the other hand, the worker pulls the jig (400) so that the head member (210) is positioned at the corner casting (C11) of the container (C), thereby connecting the head member (210) to the corner casting (C11) of the container (C).

[0265] When the head member (210) is coupled to the corner casting (C11) of the container (C) using the jig (400), the lower end of the load member (220) is connected to the load holder (231) of the fixed member (230). At this time, the load member (220) is fixedly connected by adjusting its position inside the load holder (231) so that the length can be connected to the first auxiliary structure (AS1) provided on the upper part of the top bridge (20) or the second auxiliary structure (AS2) provided on the upper part of the lashing bridge (330).

[0266] When the connecting portion (232a) of the fixed member (230) is connected to the first auxiliary structure (AS1) or the second auxiliary structure (AS2), the tension of the load member (220) is adjusted using the tightening portion (232b) to complete the installation work of the container fixing device (200).

[0267] The dismantling process of the container fixing device (200) can be performed in the opposite manner to the installation process described above. That is, after the load member (220) is separated from the fixing member (230), the head member (210) can be separated from the container (C) using a jig (400).

[0268]

[0269] The container fixing device (200) of the present invention configured as described above can minimize container (C) loss by increasing the lashing strength of the outermost container (C) loaded in multiples on the outermost side of the upper deck (11) on the left and right sides of the hull (10), and can be applied to various bridges as well as the top bridge (20) equipped on the container carrier (1) of the second embodiment described above or the lashing bridge (330) equipped on the container carrier (1) of the third embodiment described above.

[0270] In addition, the container fixing device (200) of the present invention can be applied not only to the outermost container (C), but also to a container (C) loaded on the inside of the outermost container (C).

[0271] In addition, the container fixing device (200) of the present invention can be easily applied when modifying an existing container carrier.

[0272] In addition, the container securing device (200) of the present invention can operate effectively in extreme maritime conditions where a container (C) loaded on the upper deck (11) may be lost at sea due to severe movement of the container carrier (1).

[0273] In addition, when the container fixing device (200) of the present invention is installed so as to have an upward slope in the longitudinal direction of the container (C) by connecting to holes (not shown in the drawing symbol) provided toward both sides of the container (C) in each of the corner castings (C11) provided at the lower edge of the upper container (C) and the upper edge of the lower container (C), as illustrated in FIG. 14, it can avoid interference with the lashing member (340) that is installed so as to have an upward slope in the longitudinal direction of the container (C) by connecting to holes provided toward the front and rear sides of the container (C) in each of the corner castings (C11) provided at the lower edge of the upper container (C) and the upper edge of the lower container (C).

[0274] In addition, the container fixing device (200) of the present invention can adjust the operational effect in normal operation conditions and bad weather operation conditions by installing a retaining member (233) between the tightening member (232b) and the load holder (231) in the fixing member (230). The operation conditions and function settings are described below.

[0275] That is, the container fixing device (200) of the present invention can perform two main functions: performing a function of reinforcing lashing strength in normal operation conditions and performing a function of minimizing collapse and loss of a container (C) in bad weather operation conditions.

[0276] First, the container securing device (200) of the present invention has a function that can simultaneously reinforce lashing strength during normal operation and minimize collapse and loss of containers during operation in bad weather.

[0277] In general, among the multiple containers (C) loaded on the upper deck (11), the outermost container (C) loaded in multiples on the outermost side has a relatively large acceleration resultant force and is greatly affected by wind load, so the number of loaded units and the total loaded weight are relatively reduced compared to the containers (C) loaded on the inside of the outermost container (C) at other locations.

[0278] The container securing device (200) of the present invention has a rigidity-adjustable retaining member (233) for the purpose of reinforcing the lashing strength of a plurality of outermost containers (C) loaded on the upper deck (11), thereby enabling the retaining member (233) to be used simultaneously in both normal and adverse weather conditions, thereby increasing the lashing strength in normal operation conditions and minimizing collapse and loss of containers (C) in adverse weather conditions. In addition, compared to before using the container securing device (200) of the present invention, the number of stacked outermost containers (C) can be increased to be the same as or similar to the number of stacked containers (C) loaded on the inner side. At this time, the tensioner (232) adjusts the load member (220) to have a general tension.

[0279] Second, the container fixing device (200) of the present invention has a function capable of minimizing container collapse and loss during operation in bad weather.

[0280] The container securing device (200) of the present invention operates effectively when, through rigidity control using the retaining member (233), only a certain amount of tension is generated to prevent the head member (210) from being separated from the corner casting (C11) of the container (C) under normal operation conditions, and when the movement of the loaded container (C) increases in bad weather and a certain amount of movement occurs, which increases the possibility of loss of the container (C), i.e., when a displacement with a high risk of collapse occurs. This is because, under normal operation conditions, the lashing strength reinforcement function is minimized using the retaining member (233), so that the natural movement of the entire loaded container (C) can be maintained, while also preventing unnecessary waste of force in terms of durability. At this time, the tightening member (232b) that generates tension is not tightened to the end of the guided marking part. Thereafter, the spring rigidity is used up to a certain level of movement, and in severe movement in bad weather, the load is transmitted to the main tensile member.

[0281] In addition, when the container fixing device (200) of the present invention is installed in the upper and lower containers (C) and operates, as shown in FIG. 17, a force induced by the separation of the upper and lower containers (C) and a force induced by the tension of the load member (220) are generated in the head member (210). The description of each force is as follows.

[0282] The force induced by the separation of the upper and lower containers (C) causes tension in the vertical portion of the triangular head member (210) that connects the corner castings (C11) of the upper and lower containers (C) when a lifting force is generated on one of the upper and lower containers (C) where the container fixing device (200) is installed. The head member (210) operates separately from the existing twistlock, and its applied load and response may vary depending on the clearance with the corner casting (C11). However, it is desirable in terms of strength to be designed so that the same load as the twistlock is basically applied. Although it is not the same portion from the corner casting (C11), it is a structure that receives loads in all hole portions formed in the corner casting (C11), so it should be manufactured so that the design is not disadvantageous in terms of strength due to load concentration.

[0283] The force induced by the tension of the load member (220) corresponds to the case where the tension is applied to the load member (220) on the side where compression occurs in the upper and lower containers (C) on which the container fixing device (200) is installed, that is, on the side where the upper and lower containers (C) fall. In this case, a complex load is formed on the head member (210), and the moment component that may occur in the head member (210) is minimized by using the joint (212) connecting the head member (210) and the load member (220) as a 2-knuckle joint, but the moment applied to the head member (210) cannot be avoided due to the shape of the head member (210), the direction of the force, and the eccentricity of the force. To control this as much as possible, the container fixing device (200) is designed to be supported by a corner casting (C11) and to apply the lever principle, thereby enabling the moment generated in the head member (210) to be converted into tension.
