The upper one projection 18b of the first restraint 16 is inserted into the lower hole 21a of the first restraint, and the other lower protrusion of the first restraint 16 is inserted into the upper hole 21b of the other small container 14 at the lower tier. While the part 19a is inserted, the other upper protrusion 19b of the first restraining device 16 is inserted into the lower hole 21a of the other small container 14 in the upper stage. As a result, the one small container 14 and the other small container 14 that are adjacent to each other in the boat width direction B are restrained by the first restraint 16 at a predetermined interval S in the boat width direction B.

At this time, the small containers 14 are stacked in the following procedure. That is, as shown in FIG. 12 (a), first, the small containers 14 are lowered to the lowermost portions of the stacking spaces 11a and 11b, and the small containers 14 adjacent to each other in the boat width direction B are separated by the first restraining device 16. to bound. Thereafter, as shown in FIG. 12B, the second-stage small containers 14 are stacked on the lowermost small containers 14, and the second-stage small containers 14 adjacent to each other in the ship width direction B are separated from each other. 12 with the restraint 16 of FIG.
(C), the small containers 14 of the third and subsequent stages are stacked in the same procedure.

As described above, conventionally, a plurality of small containers 14 are sequentially stacked in the same upper and lower layers, and the above-described stacking procedure is hereinafter referred to as a horizontal stacking method. As shown in FIGS. 8 and 9, each of the small containers 1 stacked in the stacking space 11 a next to the ship side wall 23.
4 is restrained by the second restraining tool 24 at a predetermined interval S in the width direction B of the boat on the side wall 23. That is, as shown in FIG. 13 and FIG.
Reference numeral 4 denotes a connecting plate 25 which is detachably attached to the inner surface of the ship side wall 23 and protrudes inward, and an engaging body 26 which is detachably provided at a tip end of the connecting plate 25. The engagement body 26 has a pair of upper and lower protrusions 27 a and 27 b, and is provided with a mounting hole 28

According to this, when a plurality of small containers 14 are stacked in the stacking space 11a next to the ship side wall 23, the lower projections of the second restraint 24 are inserted into the upper holes 21b of the lower small containers 14. Portion 27a is inserted and the lower hole 21 of the upper small container 14 is inserted.
The upper protruding portion 27b of the second restraining tool 24 is inserted into a. As a result, each small container 14 is restrained by the second restraining tool 24 at a predetermined interval S in the boat width direction B on the boat side wall 23.

Further, as shown in FIG. 15, a hatch cover 32 for opening and closing the hatch is provided on the deck of the container ship 10.
33 are provided. The hatch covers 32 and 33 are provided at a plurality of locations in the boat width direction B. Below the adjacent position C and hatch cover 32 and the other hatch cover 33 of these one is adjacent, small containers of one D ₁ adjacent to each other in the ship width direction B 14 and the other D ₂ of the small containers 14
The first restraining device 16 is not attached between the pressure adapter and the pressure adapter 35 that receives only the load Fa in the compression direction along the boat width direction B. FIG.

One end of the 5 contrast inserted Datsu抜capable between the upper small containers 14 and the lower small container 14 of D _1, and the upper small containers of the other end portion and the other D ₂ of the pressure adapter 35 14 And the small container 14 at the lower stage.

The reason for mounting the pressure adapter 35 as described above is as follows. That is, when unloading the small container 14 and only unloading the small container 14 below one of the hatch covers 32 at one port, only one of the hatch covers 32 is opened and closed to save the unloading time. Hatch cover 33 is kept closed. Thus, whereas when the small containers 14 and the other D ₂ of the small containers 14 of D ₁ are restrained by the first restrainer 16, whereas D ₁ of the small containers 14
The can not be taken out from one of the hatch cover 32, small containers 1 of this reason, whereas D ₁
It is provided Datsu抜possible pressure adapter 35 between the 4 and the small containers 14 of the other D _2. Further, when loading small containers 14, only one hatch cover 32 is opened and closed at one port, and the small containers 14 are stacked under one hatch cover 32 by the conventional horizontal loading method, and then loaded at another port. The other hatch cover 33
Only the small container 14 is opened and closed, and the small containers 14 are stacked under the other hatch cover 33 by the conventional horizontal stacking method. In this case, among the small containers 14 which are already stacked beneath the one hatch cover 32 when, set with the first restraint 16 between the upper and lower small container 14 of the other hand D ₁ in the lower of the adjacent position C, among small containers 14 to be stacked below the other hatch cover 33, the below the adjacent position C of the contrast D ₁ small containers 14
When stacking hung a small container 14 of the other D ₂ adjacent to, it is because such first restraint 16 which is set in a small container 14 of the other hand D ₁ gets in the way.

Furthermore, whereas D ₁ of the upper and lower both stages small containers 14 and the upper and lower stages of the other D ₂ small containers 14

[0011]

However, in the above-mentioned conventional type, a plurality of small containers 14 are stacked vertically in a specific stacking space 11a, and after the stacking of the small containers 14 in the stacking space 11a is completed. However, the vertical stacking method in which the small containers 14 are stacked one above the other in the stacking space 11b adjacent in the ship width direction B cannot be performed.
That is, for example, the small container 14 is lowered to the bottom of the specific stacking space 11a shown in FIG.
The lower one protrusion 18a of the first restraining device 16 is inserted into the upper hole 21b of the lowermost small container 14, and the upper one protrusion 18b of the first restraining device 16 is inserted.
Into the lower hole 21a of the small container 14 of the second stage, the small container 14 of the second stage is stacked on the small container 14 of the lowest stage, The containers 14 are stacked. In this way, after stacking a plurality of small containers 14 in a specific stacking space 11a in a vertical line and then trying to stack the small containers 14 in the adjacent stacking space 11b shown in FIG. The first restraint 16 projecting in the ship width direction B from above and below the small container 14 shown in (a) becomes an obstacle, and the small container 14 shown in (b) cannot be lowered into the adjacent stacking space 11b. That's why. As described above, in the related art, there is a problem that a plurality of small containers 14 can only be stacked in the horizontal stacking method (see FIG. 12), but cannot be stacked in the vertical stacking method.

[0015] As shown in FIG. 15, one hatch cover 32 and the other hatch cover 33 are adjacent to each other in a ship width direction B below an adjacent position C adjacent to the other hatch cover D _1.
Between the small containers 14 of small containers 14 and the other D ₂ of the first restraint 16 is not mounted, instead, the pressure adapter 35 is provided, small containers 14 and the other D of the contrast D _{1 2} , the load F in the compression direction along the ship width direction B.
Only a is received by the pressure adapter 35.

As described above, the small containers 14 adjacent to each other in the ship width direction B on the same upper and lower layers are not all connected to each other by the first restraining device 16 and are restrained, but are connected below the adjacent position C. Since the (restraint) is interrupted, when the container ship 10 swings in the boat width direction B, the load Fb acting on each of the second restraints 24 in the compression direction increases. Accordingly, it is necessary to improve the strength of each of the second restraining members 24, so that there is a problem that each of the second restraining members 24 becomes large and the weight increases.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a container stacking restraint which does not hinder the stacking of containers on a ship in a vertical stacking system.

[0015]

According to the first aspect of the present invention, a container stacking restraint for a container ship comprises a vertically stacked container and an adjacent container stacked next to the container. And a stacking restraint that restrains at a predetermined interval in the horizontal direction, wherein the restraining body is rotatable in a horizontal plane with one engaging body having a pair of upper and lower engaging portions, and one engaging body. The other end of the movable arm having a pair of upper and lower engaging portions is detachably provided at a free end of the movable arm, and each of the one and the other Each part is configured to be freely disengageable from engaged portions formed at both upper and lower ends of each container, and when the engaging portion of the one engaging body is engaged with the engaged portion of the container, The movable arm is the other An engagement position where the engaging portion is engageable with the engaged portion of the container adjacent to coalescence, is to pivot between a retracted position retracted from the stacking space next to the container.

According to this, the lower engaging portion of one of the engaging bodies of the restraint body is engaged with the upper engaged portion of the lower container, and at this time, the movable arm of the restraining body is moved to the retracted position. By rotating, the movable arm is retracted from the stacking space of the adjacent container. Thereafter, the upper engaging portion of one of the engaging members of the restraint body is engaged with the lower engaged portion of the upper container, and the upper container is stacked on the lower container. Furthermore, by stacking a plurality of containers in a line in the upper and lower directions in the same procedure, the restraint body is set between the upper and lower sides of each container.

When adjacent containers are stacked next to each other in the horizontal direction at predetermined intervals in the horizontal direction, the movable arms of the upper and lower restraint bodies are located at the retracted position and are adjacent to the adjacent containers. The movable arm does not hinder the lowering of the container in the stacking space of the adjacent container because the container is retracted from the stacking space of the adjacent container. After the container is lowered to the stacking space of the adjacent container in this manner, the movable arm of the restraint body is rotated from the retracted position to the engaged position. Thus, the free end of the movable arm projects above the adjacent lower container. Then, the other engaging body is attached to the free end of the movable arm, and the lower engaging part of the other engaging body is engaged with the upper engaged part of the adjacent lower container. Thereafter, the upper container is stacked on the adjacent lower container, and at this time, the upper engaging portion of the other engaging body is engaged with the lower engaged portion of the upper container. Furthermore, by stacking a plurality of adjacent containers in a vertical line in the same procedure, the containers stacked in a vertical line and the adjacent containers stacked next to these containers are restrained at the same vertical level. Are mutually restrained at predetermined intervals in the horizontal direction.

By retreating the movable arm of the restraint body set between the upper and lower sides of the already stacked containers to the retracted position, the movable arm hinders the stacking of adjacent containers. Therefore, containers can be stacked vertically. In the container stacking restraint of the container ship according to the second aspect of the present invention, holes are formed at both upper and lower ends of each container as engaged portions, and the engaging portions are vertically insertable into and removable from the holes. In this case, a simple projection is used.

According to this, the lower projection of one of the engaging members of the restraint body is inserted into the upper hole of the lower container, and at this time, the movable arm of the restraint body is rotated to the retracted position. And evacuate from the stacking space of the adjacent container. Then, the upper protrusion of one of the engaging members of the restraint body is inserted into the lower hole of the upper container, and the upper container is stacked on the lower container.
Furthermore, by stacking a plurality of containers in a line in the upper and lower directions in the same procedure, the restraint body is set between the upper and lower sides of each container.

When the adjacent containers are stacked next to each other in the horizontal direction at predetermined intervals in the vertical direction, the containers are lowered into the stacking space of the adjacent containers, and then the movable body of the restraint device is moved. The arm is rotated from the retracted position to the engaged position. This allows
The free end of the movable arm projects above the adjacent lower container. Then, the other engagement body is attached to the free end of the movable arm, and the lower projection of the other engagement body is inserted into the upper hole of the adjacent lower container. Thereafter, the upper container is stacked on the adjacent lower container, and at this time, the upper protrusion of the other engagement body is inserted into the lower hole of the upper container. Furthermore, by stacking a plurality of adjacent containers in a vertical line in the same procedure, the containers stacked in a vertical line and the adjacent containers stacked next to these containers are restrained at the same vertical level. Are mutually restrained at predetermined intervals in the horizontal direction.

In the container stacking restraint of the container ship according to the third aspect of the present invention, the other engaging member is removably inserted into a mounting hole formed at a free end of the movable arm, and the movable body is provided with a movable arm. It is provided so that the position can be freely adjusted in the length direction. According to this, when stacking adjacent containers at predetermined intervals in the horizontal direction next to the already stacked containers, the movable arms of each restraint body are rotated to the retracted position, and the stacking space for the adjacent containers is kept. After lowering the container, the movable arm of the restraint body is rotated from the retracted position to the engaged position.
Thus, the free end of the movable arm projects above the adjacent lower container. Then, the other engaging body is inserted into the mounting hole for mounting. At this time, by adjusting the mounting position of the other engaging body in the length direction of the movable arm,
The position of the lower engaging portion of the other engaging body can be accurately adjusted to the position of the upper engaged portion of the adjacent lower container. Therefore, even if the position of the adjacent container is slightly shifted, the adjacent containers can be restrained by the restraint by adjusting the mounting position of the other engagement body as described above.
