Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is preferably used in a container ship, in which the longitudinal direction of the container or container ship is separated by a transverse end wall or bulkhead, and the transverse direction of the container is separated by a transverse end wall or a bulkhead. a vertical space defined by pairs of vertically extending partition guides that are opposite to each other, said partition guide pairs projecting from a lateral end wall or bulkhead and having a narrow dimension when viewed in the lateral direction; The present invention relates to a container storage device in which a guide surface is provided on the top of at least one of a wall or a partition wall and is inclined downward toward the inside of a vertical space.

(Prior Art) Today, in container transportation, attempts are being made to increase the capacity of each cargo ship in order to reduce transportation costs without increasing the size of the cargo ship.
The width of a cargo ship is determined by the width of the strait through which it normally travels. The width of a ship passing through the Panama Strait is generally 32.2 m, for example.

U.S. Pat. No. 3,827,384 discloses a T-shaped profile as opposed webs laterally bounded by vertically extending partition guides and vertically bounded by transverse end walls. It describes a method of stacking containers one after another in a vertical space (shaft). These vertical spaces are often sized to accommodate so-called 40-foot (12.2 m) containers. Additionally, this vertical space can be extended from a 40-foot container to 20 feet (6.1 m) by installing a lateral bulkhead.
It is known to change the container to a storage container. In this case, the lateral bulkheads create vertical space for two rows of 20 foot containers arranged laterally in sequence.

(Problem to be Solved by the Invention) In an attempt to reduce transportation costs by utilizing the width of a cargo ship, increasing the number of vertical spaces arranged in the lateral direction of the ship is an attempt to reduce the number of loading and unloading spaces in the vertical spaces. is constrained by the need for larger vertical space dimensions in order to be able to perform the process quickly. Therefore, there must be some lateral play between each container and the vertical space.

Furthermore, relatively narrow partition guides are determined by strength requirements and therefore do not allow for the provision of sloped guide surfaces in relation to the surfaces present on the lateral walls.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a container storage device that can maximize the width of a cargo ship without having a major adverse effect on the loading and unloading of containers.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the container storage device according to the present invention makes the upper ends of the partition guide pairs vertically opposed to each other in each vertical space almost at the same level, The present invention is characterized in that the pair of partition guides on one side of each vertical space is at a different height from the pair of partition guides on the other side of each vertical space when viewed in the lateral direction.

(Operations and Effects) According to the present invention, in the carrying-in operation, each container is guided down to above the partition guide pair whose upper end is at a lower level in the vertical space into which the container is to be carried.
At this time, the inclined guide surface of the lateral end wall is used to properly position the container in the vertical direction. The container is then laterally guided in vertical space to abut the container against a portion of the other pair of higher level partition guides extending above the lower level partition guide. The container then descends into the vertical space, passes through the partition guides at the lower level and slides along the sides of the partition guides at the higher level. In this way, even in the case of a vertical space for a 20-foot container, where there is no room for a guideway in the transverse bulkhead used to divide the vertical space for a 40-foot container into a vertical space for a 20-foot container, an inclined guideway can be used. The lowering operation can be carried out by sliding the container along a lateral end wall having a lateral end wall. Therefore, even if the lateral dimensions of the vertical spaces are made as small as possible and only narrow partition guides are provided, the container can be quickly positioned within each vertical space.

In a preferred embodiment of the invention, the high level partition guide pair extends to a level above the lowest edge of the guide surface in at least one end wall. With this configuration, the vertical guiding movement of the container can be performed simultaneously with the horizontal guiding movement.

In a preferred embodiment of the invention, the height difference between adjacent pairs of partition guides is approximately 400 mm.

Furthermore, in a preferred embodiment of the invention, the partition guide extending at least to a high level has an upwardly enlarged projection which is coplanar with the partition guide and extends from both sides of the partition guide. It shall have a plane that almost coincides with the side surface of. According to this configuration, the reliability of proper guidance of containers, which tend to be arranged at an angle with respect to the vertical space, is further improved. Furthermore, the advantage is that the strength of the guide surface is increased.

Furthermore, in a preferred embodiment of the present invention, the partition guide is sloped along its upper edge. According to this configuration, each container can be easily guided within the vertical space between the partition guides.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a schematic perspective view of a part of a container storage device 1 according to the invention. The illustrated portion of the equipment includes eight vertical spaces 2 each containing 20 ft (6.1 m) vertically stacked containers.
There are ~9. The longitudinal (vertical) direction of this device is arrow 1.
0 direction. The container storage device is placed on the ship so that this longitudinal direction coincides with the longitudinal direction of the container ship. The vertical space described above is created by dividing a 40 foot (12.2 m) container space into four spaces separated by narrow, laterally extending transverse bulkheads 11. This partition wall is the tension absorbing device 12~
19 to maintain the proper position. This tension absorbing device may be a cable or a thin bar. These tension absorbing cables 12 to 19 are connected to the lateral bulkhead 11
and laterally extending lateral end walls 20, 21 located at both ends of a large space for a 40-foot container. Thus, the vertical spaces 2-9 for a 20-foot container are separated by lateral end walls 20, 2, respectively.
1 and a part of the partition wall 11.
This partition wall 11 forms the second end wall of each vertical space. Furthermore, each of these vertical spaces is provided with partition guide pairs 22, 23;
5; 26, 27; 28, 29; 30, 31; 3
2,33; 34,35 and 36,37. These partition guides include a lateral end wall, that is, a first end wall 20, 21, and a lateral partition wall 1, which is a second end wall.
1 and has a relatively narrow width when viewed in the lateral direction of the device. The outermost vertical spaces 2, 6 in the drawing are delimited on their opposite sides from the other vertical spaces by longitudinal walls 38.

Each pair of mutually opposing partition guides 22-37 extends to substantially the same height level as shown by the dotted lines. Furthermore, on one side of the vertical spaces 2 to 9 one pair of partition guides extends to a higher level than the other pair of partition guides on the other side. In this connection, the longitudinal wall 38 can be considered as an integral partition guide on one side of the outermost vertical spaces 2 and 6. When viewed from the left-hand corner of FIG. 1, the vertical spaces are alternately separated by long pairs of partition guides and pairs of short partition guides.

The end walls 20, 21 of the vertical space for an open 40 foot container are provided with further upwardly extending guide surfaces 39, 50, respectively, which guide surfaces slope downwardly into the interior of the vertical space.

FIG. 2 is a longitudinal cross-section of the vertical space 4 on the - line in FIG.
so that it is at a level located on a plane that intersects the inclined guide surface 39 of 0. Furthermore, the upper end 41 of the other partition guide 25 is positioned on a plane below the upper end 42 of the partition wall 11. Furthermore, as shown in FIG. 2, the upper end of the partition guide is provided with inclined surfaces 43 and 44 on both end surfaces, respectively. The inclined surfaces slope downwardly into the vertical space on the side of the inclined surfaces.

FIG. 3 shows a modified example of the partition guide, which corresponds to the above-mentioned partition guide 24 extending in the vertical direction and will be described with a dash. Partition guide 24'
A protrusion 45 is formed on the partition wall 45 to extend on the same plane as the partition wall formed by the pair of partition guides. Therefore, this protruding portion 45 is also delimited on both side surfaces by the same surfaces as the side surfaces of the remaining portion of the main body of the partition guide.

Despite the relatively small lateral clearance for each container, the container storage device described above allows for rapid loading of containers into vertical spaces. i.e., vertically positioning the container above a pair of short partition guides between two adjacent vertical spaces until the bottom of the container reaches a level below the level of the upper end of the adjacent long partition guide. Loading can be done quickly by lowering the vehicle. During this work, the vertical guidance of the container storage device is
corresponding inclined guide surfaces 39 or 50 in vertical spaces
This is done by sliding the container downwards along the Next, the container is supported on the short partition guides until the container abuts against the pair of long partition guides forming the other side of the vertical space. The container then slides downward (preferably on the end wall 20 or 21 with the guide surface and on the long partition guide pair).

The individual partition guides are formed, for example, by projecting webs with a T-shaped profile. Alternatively, a rectangular bar can be welded into a chevron shape. Furthermore, the partition guide can also be of the RHS type with a hollow cross section. The thickness of the partition guide is generally about 30 mm, but the thickness is determined by strength conditions. The difference between the long partition guide and the short partition guide is preferably about 400 mm. Preferably, the lower edge of the inclined guide surface is approximately 150 mm below the level of the upper end 42 of the partition wall 11. The container storage device according to the present invention can quickly and reliably introduce a container into a vertical space even if the guide has only about 0.25 mm of play in the lateral direction of each vertical space (with the exception of the play below the vertical space). can. This guidance is obtained without affecting the thickness of the partition guidance and without reducing the number of vertical spaces with respect to the transverse direction of the ship.

What has been described above merely shows preferred embodiments of the present invention, and various modifications can be made within the scope of the claims. For example, the container storage system could initially have only vertical space for a 20-foot container and no bulkhead 11. Further, the container storage device may be designed to handle only 40-foot containers, and the bulkhead 11 may not be provided. In the above embodiment,
The pairs of partition guides are alternately provided with short ones and long ones, but it is also possible to use partition guides with two or more lengths by using a partition guide with an intermediate length. You can also do it.
