Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for loading and holding containers on a multi-purpose cargo ship for transporting grain, coal, lumber, etc.

Multi-purpose cargo ships need to be able to load and unload a variety of cargoes.
Therefore, when loading containers, it is not possible to use a container loading and holding device that is firmly fixed in the ship's hold, as in a full container ship.

For this reason, guides that can be easily attached and detached are provided to connect and position the containers that are adjacent to each other vertically, horizontally, front and rear, and furthermore, the lowest container and the lowest container due to the play that exists between the guide and the container are connected and positioned. In order to prevent the spread of misalignment with the upper container and to prevent container damage, the seventh
It was decided to use a long chucking beam 20 as shown in the figure.

The chucking beam 20 has engaging protrusions 21, 21, . Alternatively, a tilting guide removably provided on the wall of the ship's hold can be engaged.
Further, the distance between the engaging protrusions is set on the top of the container,
The spacing is made equal to the spacing between the engagement recesses formed in the corners of the lower surface.

If such a chucking beam 20 is used, the misalignment between the lower container of the chucking beam 20 and the upper container of the chucking beam 20 can be prevented by the engaging protrusion and the engaging recess. This distance corresponds to the play that exists between the two, and the intended purpose of preventing the expansion of misalignment can be achieved.

Furthermore, the load of the containers above the chucking beam is prevented from being applied to the containers below, thereby preventing damage to the containers due to rolling, pitching, etc.

However, when loading and unloading containers using this tilting beam, when loading and unloading containers located below the tilting beam, it is necessary to A certain container must be completely unloaded in advance.

This drawback does not become apparent when all containers are loaded at one port and unloaded at another port, but such cases are extremely rare, and in most cases, It is necessary to load containers little by little at several ports and unload containers little by little at several ports.

Since it is not known at all until the container is loaded at which port a container loaded at one port will be unloaded, it is possible to efficiently divide the loading of containers at one port by destination. Even if the situation changes, the destination of containers at other ports cannot be predicted.

Therefore, in reality, the above-mentioned drawbacks cannot be overcome, and the efficiency of loading and unloading containers is reduced.

The present invention solves the above-mentioned drawbacks by configuring the jocking beam main body and the engagement protrusion separately, and will be described in detail below with reference to the accompanying drawings showing embodiments.

FIG. 1 is a plan view of the container loading and holding device of the present invention, FIG. 2 is an enlarged front view of the same main part, and FIG.
FIG. 2 is a cross-sectional view, and FIG. 4 is an enlarged plan view of the main part, which is composed of a jocking beam main body 1 and a connecting member 2.

The chucking beam main body 1 has recessed steps at predetermined positions on both sides of a highly rigid rod having a predetermined width, a predetermined height, and a length approximately equal to the width of the hold, at intervals approximately equal to the width of the container 3. I'm wearing 4,4...

The connecting member 2 is provided with a protrusion 5 inserted into the recessed step 4 at a predetermined position on one side of a plate having a predetermined planar shape and a predetermined thickness, and at predetermined positions on the upper and lower surfaces of the plate. , protrusions 7 that engage with engagement recesses 6 formed in the upper and lower corners of the container 3 are provided.

Incidentally, reference numeral 8 denotes a racking fixing metal fitting set at a predetermined position on the upper surface of the jocking beam main body 1.

The operation when loading containers using the container loading and holding device having the above configuration is as follows.

The lowest container is positioned and stowed on the deck in the hold using guide fittings that connect adjacent containers in the front, rear, left and right directions, and a guide with almost the same configuration as above is placed on top of the lowest container. Position and stack the second tier container using metal fittings. Therefore, the second-level container is located directly above the lowest-level container.

Next, when stacking the third tier of containers, the container stacking and holding device of the present invention is installed as shown below.

That is, the chucking beam main body is supported between the chucking guides 9, which are removably fixed to the hold wall so that its upper surface is slightly higher than the top surface of the second-tier container, and is further connected. Part 2
By fitting the protrusion 5 into the recessed step 4 of the chucking beam main body, a protrusion 7, 7 is formed in an engagement recess 6 at a corner of the upper surface of the second stage container.
6. Here, the chucking beam main body is positioned within the gap between adjacent containers.

Thereafter, containers in the third and higher tiers are stacked in the same manner as described above.

The topmost container is fixed to the hold wall using a topside chock.

Moreover, one end of the chucking beam main body is fixed to the chucking guide 9 on the hull wall side, and the other end is freely abutted and supported on the chucking guide 9 on the center partition wall side. There is.

Further, by using the metal fittings 8, 8, . . . provided on the upper surface of the chucking beam main body, lashing may be performed between the container and the container located above the container stowage holding device, or only lashing may be performed.

In addition, if the distance between the outermost container and the inner wall surface of the ship's hold is small, a wooden wedge may be installed between the container other than the container that engages with the container loading and holding device of the present invention and the inner wall surface of the ship's hold. It is also possible to insert and secure the container with this wedge.

The operations when loading and unloading containers are as follows.

For containers located above the container stowage holding device of the present invention, top side jocks, guide fittings, lashings, etc. are removed to free adjacent containers, and then the desired container is pulled up using a crane or the like.

If it is necessary to unload a lower container, it is not necessary to unload all the containers located above the container to be unloaded.
It is sufficient to load and unload the minimum number of containers necessary for loading and unloading the containers.

Furthermore, even when loading and unloading a container located lower than the container loading and holding device of the present invention, the long chucking beam main body is located within the gap between the containers, so the engagement protrusion 2 at the necessary location It is only necessary to remove the container, so the container can be easily loaded and unloaded.

The above has described an embodiment in which the container loading and holding device of the present invention is provided between the second-tier container and the third-tier container, but it may also be provided at different height positions, or It may be provided at a plurality of different height positions.

Furthermore, if connecting members 2 with different wall thicknesses are prepared,
Even when containers with a height of 8 feet and 8 feet and 6 inches are mixed, they can be stacked without any inconvenience.
Loading and unloading can be done.

Further, as the engagement protrusion 2, one protrusion 7 provided on the upper and lower surfaces may be used as a set of two.

As described above, in the present invention, since the horizontal load of the container is also received by the container stowage holding device, the lower container does not receive all of the horizontal load of the upper container as in the case of stowage using only guide fittings. For this reason, even if the ship's hull rolls, the displacement of the container will not be magnified or the container will not be destroyed. Furthermore, since the container stowage holding device is located within the gap between adjacent containers, it is not necessary to remove the container stowage holding device even when loading or unloading a container below the container holding device. ,
Therefore, it has the unique effect of being able to load containers by destination at many ports and efficiently unload the containers at the destination.
