Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a container support for stably stacking containers inside a hold of a container ship or in a hutch cover of a wooden container.

[Prior art] - In I'IQ, there are containers for shipping that have almost the same width and different length dimensions, and among these, the container that has been standardized by the ISO standard and is the most commonly used. These include containers with a length of 48 feet, 45 feet, or 40 feet, and small containers (hereinafter referred to as "rate containers") with lengths of 20 feet or 12 feet.

These containers are transported inside a hold of a container ship or the like, or stacked on haunch covers that are carried inside a hold on a deck.

As shown in Figures 5 and 6, inside the hold of a container ship, there is a container guide A that fits and supports containers, and prevents stacked containers from falling apart. .

This container guide A is formed to correspond to the external shape of a large-sized container such as a standard type 40 feet or 45 feet, so that the four corners of the container come into contact and fit into it. The containers are fitted inside the container guide and stacked one after another for storage.

The stacked containers are connected via fixing fittings attached to each corner of the containers and connecting fittings such as stacking pieces and positioning cones.

For example, as shown in FIG. 2, when using a stacking piece D having a structure in which a mounting flange 7 and a locking protrusion S having a locking launch 8 are provided on both sides of a base plate 6, there is a gap between the stacked upper and lower containers. Attach the mounting flange 7 and retaining protrusion 9 of the stunking piece D to the fixing fittings C and C, respectively.
Connect by engaging and preventing removal. Further, the lowermost container is fixed on the floor by connecting the fixing fitting on the lower surface to the fixing fitting provided on the floor of the hold through a connecting fitting such as a stamping piece.

On the other hand, in order to load containers onto the hatch cover, as shown in FIG. There is a method of fixing the container E to the support towers F by providing a holding device 17 having a stretchable holding member 18 and pressing the containers E stacked between the support towers F by the holding device 18 of the holding device 17. It is taken.

[Problem to be solved by the invention]

By the way, the size of the container guide and the spacing between the support towers as described above are set so that large containers such as 40 feet or 45 feet can be stored in the standard type.
Since the container is formed to correspond to the external shape of the container, in order to load small containers such as 20 feet or 12 feet between the container guides and support towers inside the hold, the container Insert two small containers B in parallel into guide A, and place small container B on top of it.
This is done one after another.

However, if small containers B are stacked as shown above,
Since the free ends of both containers B that face each other are not guided by the container guide A, the ends may shift laterally from inside the container guide A as shown by the broken line in Figure 6 due to the shaking of the ship during transportation. A movement occurs. In this case, since the containers are connected to each other and the lower surface of the lowermost container is fixed to the floor of the hold, due to the above-mentioned displacement movement, the lowermost container is As shown, the weight of the cargo stacked on top causes a diagonally downward deforming force to be applied.
This causes problems such as deformation and breakage of the container.

In order to deal with the above-mentioned problems, conventionally, as shown in FIG. 6, the free ends of the small containers B are connected to each other with a connector 11 to suppress the lateral movement of the container. It is being said. However, although the above method certainly suppresses the lateral displacement of the small containers B and prevents deformation accidents, it is not possible to unload the stacked small containers B in each row, making loading and unloading work time-consuming. There is a problem.

This problem also occurs when small containers are stacked on hatch covers between support towers F as shown in FIG.

In addition, when containers are stacked between support towers and transported, all the loads applied from the containers due to the shaking of the ship, etc., act on the holding device that secures the containers.
The holding device itself needs to have sufficient strength to withstand these loads. As a result, the weight of the holding device becomes large, which puts pressure on the load on the ship, and the increased weight on the deck has an undesirable effect on the unevenness of the ffl amount of the ship. In addition, by interposing the holding device between the support tower and the container, the equipment on the deck becomes complicated, and furthermore, the stacked containers must be fixed with a holding member, which makes loading work time-consuming. There is also.

This invention was made in view of the above problems, and an object of the present invention is to provide a container support device that allows large or small containers to be stably stacked between container guides and support towers with simple operation and structure. The purpose is

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a frame consisting of a pair of long sides and a pair of short sides attached between the ends of the long sides. Engagement holes for engagement of the connecting fittings of the container are provided on the upper and lower surfaces of both ends of the long side material, and the above-mentioned engagement holes are provided on the upper and lower surfaces of the required positions between the both ends of the long side material. be.

[Effect]

For example, in a container guide for a 40-foot container, 2
When loading a 0-foot small container, as shown in FIG. The width of the frame body 30 is set to be the same as the width of the guide A, and the four corners of the frame body 30 are formed to fit into the container guide A.
An engagement hole 32 with which a connecting fitting engages is provided at both ends of the long side material 31, and two engagement holes 33 are provided in parallel on the upper and lower surfaces of the central portion of the long side material 31. Then, the container support is attached to the container guide, interposed between the containers, every time two small containers fitted in parallel are stacked in several stages.

In this state, the container support is guided with each end of the long side material 31 in contact with the container guide A, and the engagement holes 32 and 33 at both ends and the center of the container support are parallel to each other in the guide. The small container B is positioned so as to correspond to the engagement hole of the fixing fitting of the small container B.

Attach the support to each engagement hole 32.3 of the container support.
3 and the fixing fittings of the upper and lower small containers are connected via a connecting fitting such as a stacking piece or a positioning cone. When stacked in this way, the four corners of the container support are guided by the container guide and their movement is fixed.
Each small container is immobilized within the container guide via a support.

The above example shows the case where it is used in common for 40 feet and 20 feet containers, but for example, when it is used in common for 40 feet and 12 feet containers, the long side material 31 of the frame 30 as shown in FIG. When three 12-foot containers are arranged in parallel between both ends of the container, engagement holes 32 and 33 of the connecting fittings are provided at positions corresponding to the fixing fittings of each container. In this case, the engagement holes 32 at both ends of the long side material 31 are commonly used for both 40-foot and 12-foot containers.

Further, the container support described above can also be used for fixing large containers such as 45 feet and 40 feet to each other. In this case, as shown in FIG. 15, engagement holes 32 are provided at both ends of the long side material 31, and engagement holes 33 are provided at a position 5 feet inside from one end. That is, in the case of a 45-foot container, the engagement holes 32 at both ends are used, and in the case of fixing a 40-foot container, the engagement holes 32 at one end and the inner engagement hole 33 are used. In this way, the required position referred to in the "claims" is appropriately set depending on the size of the container to be shared.

On the other hand, when containers are loaded on the hatch cover, the length of the frame is made the same as the distance between opposing support towers, and the width of the frame is made the same as the width of the container. Similar to the above, this container support is provided between opposing support towers.
It is installed by interposing it between the containers every several stacks of containers.

Further, the container support and the container are connected by a connecting fitting such as a stacking piece or a positioning cone.

Cargo handling work can be carried out for each row of stacked containers by sequentially performing the above-described connection and disconnection work between containers and container supports.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

The container support 1 shown in FIG. 1 is commonly used for 40-foot containers and 20-foot containers, and includes a substantially rectangular frame 2 formed to correspond to the shape of the mounting surface of the 40-foot container, and a Connectors 3 each attached to each corner of the body 2 and at a position dividing the long sap material side 2a into two equal parts.
．． It consists of 4.

The frame 2 has the external shape of a standard 40-foot container by a pair of long sides 2a, 2a and a pair of short sides 2b, 2b passed between the ends of the long sides 2a. It is formed to a corresponding size, and when fitted into the container guide A, the outer side of the connector 3 attached to each corner comes into contact with the inside of the container guide A, as shown in Fig. 4. It has become.

As shown in FIG. 2, the connector 3.4 is a U-shaped metal fitting 5a.
An engagement hole 5 is provided on the upper and lower surfaces of the container to which a connecting fitting of the container engages.In the connecting fitting 4 attached to the central part of the long side material 2a, the engaging hole 5 is provided in the longitudinal direction of the side side. Two of them are provided in parallel. As shown in FIG. 4, when the container support 1 is placed on two parallel 20-foot small containers B, the engagement holes 5 are formed so that the fixing fittings C of each of the two-handed containers B can be engaged with each other. It corresponds to the hole.

The shape of the engagement hole 5 is formed in accordance with the structure of the stacking piece, positioning cone, etc. to be used. For example, when using the stacking piece D shown in FIG. The protruding engagement latch 8 is formed in a shape that prevents it from being pulled out.

In addition, the locking latch 8 in the stacking piece D
is biased in the projecting direction by a spring provided inside the projection 9, and the latch 8 can be retracted into the projection S by rotating a handle 10 connected to the spring.

The container support 1 of the embodiment has the above-mentioned configuration, and as shown in FIG. tier) Attach each stack by interposing it between the containers.

To connect the container support 1 onto the small container B, each connector 3.4 of the container support 1 is connected as shown in the second panel.
The mounting flange 7 of the stacking piece D is fitted into the engagement hole 5 on the lower side of the stacking piece D, and the stacking piece D is placed on the small container B in this state. In this case, the engagement protrusion 9 of the stacking piece D
is fitted into the engagement hole of the fixture C of each small container B, the engagement latch 8 enters into the engagement protrusion S, and when the protrusion 9 fits inside the fixture C, the engagement latch 8 protrudes due to the elasticity of the spring and prevents the stacking piece D from being removed from the fixture C.

Moreover, when stacking the small containers 8 on the container support 1, contrary to the above, the mounting flange 7 is engaged with the lower fixing metal fitting C of the small container B, and the stunking piece D is attached. The small container B is set on the container support 1.

When small containers B and container supports 1 are stacked together in this way, each small container B is Movement is fixed by the container support 1. Therefore, deforming force due to lateral displacement as shown in FIG. 6 does not act on the small containers B, and stacking can be performed stably.

In addition, container support 1 and small container B are placed in the order in which they are stacked.
By connecting and releasing the connections, cargo handling operations can be carried out for each row of containers.

FIG. 8 shows another embodiment, this container support 20
is used to secure containers between support towers on decks.

The frame 21 of this container support 20 includes a long side material 21a,
The ends of the long side members 21a are formed to protrude from the short side members 21b, 21b, and the length of the long side members 21a is formed to be the same as the distance between the opposing support towers F, as shown in FIG. The width of the frame body 21 is formed to be the same as the width of the container. On the other hand, on the opposing inner surface of the support tower F, there is attached a support guide 22 whose width is the same as the width of the container and through which each end of the long side material 21a of the frame body 21 is guided.

Connectors 23 and 24 are attached to the long side material 21a at the center and at positions corresponding to the four corners of the 40-foot container near both ends, respectively.
24 has an engagement hole 25 formed on the upper and lower surfaces thereof, into which a connecting fitting such as a stacking piece or a positioning cone is engaged.

Two engaging holes 25 are provided in the central connector 23 in parallel in the length direction of the frame, and the positions of the engaging holes 25 are 20 feet apart, as shown by the broken line in FIG. small container 8
When two pieces are arranged in parallel and their respective corners are aligned with the connectors 24 on both ends, the positions match the positions of the fixing metal fittings 26 at each corner of the other side.

As shown in FIG. 1O, the container support 20 having the above structure is installed between the containers E each time the containers E are stacked on the hatch cover 15 between the support towers F. In this case, each of the connectors 23 and 24 of the container support 20 and the fixing metal fittings 26 of the upper and lower containers E that sandwich the container support 20 are connected by connecting metal fittings.

When the container support 20 is interposed between each container E in this way, the four corners of the container support 20 come into contact with the support guides 22 of the support tower F and the movement is stopped, so the container E It is stably fixed between F.

By the way, small containers of 20 feet or 12 feet are stacked directly on the hatch cover 15 without using a support tower, as shown in FIG. Many methods are also used to transport the material in a fixed state. In this case, the lowermost small container B is positioned on the hatch cover 15 by the deck socket 28 provided on the hatch cover 15, and the upper small containers B are connected using stacking pieces or positioning cones.

However, in the case of stacking small containers B side by side as described above, there is only an extremely narrow gap 29 between adjacent small containers B, and it is difficult to pass the lashing tools inside this gap 29. There is a drawback that it cannot be done.

Therefore, small container B is only fixed to the hatch cover in one direction, but the height at which the containers can be stacked is determined by the container's fixing force, so if the fixing force is weak as described above. However, there is a problem in that the stacking height of containers is limited and containers cannot be stacked too high.

In this case, as shown in FIG. 12, if the container support 1' according to the present invention is interposed between the small containers B stacked in several tiers, each container will be connected by the container support. The entire stack of small containers can be firmly fixed on the bunch cover. Therefore, containers can be stacked high and highly efficient transportation can be achieved. Further, in this case, an engagement hole for a lashing tool may be provided at the end of the container support, and the container support and the hatch cover may be directly fixed by the lashing tool.

In the above embodiment, a container support that can be used in common for containers of half length, 40 feet and 20 feet, is shown, but three or more small containers can be supported with one frame as shown in FIG. The structure described in the above embodiment can be used in the same way for supporting tools or for supporting tools shared between large containers with the same dirt floor as shown in FIG. 15.

〔Effect of the invention〕

As explained above, the container support of the present invention allows the movement of the container to be controlled by fitting the frame into contact with the four corners of the frame within the container guide or between the support towers, and by connecting the container to the container using the connecting fittings. Since the container is fixed between the container and the support tower, containers can be stacked stably regardless of their size.

In addition, when loading containers between support towers on a deck, there is no need to use a holding device to press and fix the containers, so the equipment on the deck can be simplified and the weight of the ship can be significantly reduced by v1. There is.

Furthermore, since the container support is only removably interposed between the containers, the stacked containers can be unloaded row by row, and the loading and unloading work can be carried out quickly.
