Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a multi-purpose cargo ship, which transports cargo of irregular size and shape such as miscellaneous goods and wood, and efficiently stows containers of fixed size and shape in its hold. We have developed a device to obtain this information.

The gist of the loading device of the present invention is that a pair of rails 2 consisting of straight rods are laid on the bottom of the ship's hold in the ship's width direction up to the inner side of the ship's side, and a slider 4 is slid over these rails. The slider is provided with a protrusion 3 that fits into the hole of the container corner fitting 7, and a blind hole 5 is provided in a predetermined position of the rail 20 to fix a stopper 9 for fixing the container to fix the container. This is what I did.

Conventionally, container loading was an improvement device for ship holds.
There is U.S. Patent No. 3,468,437, in which a container is moved on a rail protruding above the ship's hold, and is moved from a straight line to the left or right as necessary. Since there was no means for hoisting it up and stably fixing it inside the ship's bottom, it was easy to hang it from Tsuchi and transfer it into the hold, but it could not be loaded stably on a long voyage. It was difficult to hold the containers, and there was a risk of danger not only to each other but also to the ship.

In addition, the container rack used to have a large-diameter chevron crown and a small-diameter follower plug protruding from the top and bottom of a single plate to connect to the container and slide on the rail. There was a drawback that the upper and lower chevron crowns and follower plugs were easily damaged due to heavy loads on one axis.

SUMMARY OF THE INVENTION The present invention aims to eliminate the drawbacks of the prior art, to provide a device that makes full use of the space in a ship's hold, and stably stows containers using solid rails, sliders, and stoppers.

Hereinafter, embodiments of the stowage device of the present invention will be described in detail with reference to the drawings.

The hold of the multi-purpose cargo ship shown in Fig. 1 has a width wider than the width of the ship.The hold bottom 1 extends closer to the port and starboard sides of the ship.

Reference numeral 2 denotes a pair of rails, which are laid so as to be located on the lower surfaces of the front and rear ends of each container 6, so that each container 6 can be loaded with its longitudinal direction extending in the direction connecting the bow and stern of the ship. It has become.

Reference numerals 4 and 4' denote sliders, each having protrusions 3 protruding from the upper surface thereof, and the protrusions 3 are connected to respective corner fittings 7 attached to the four corners of the lower end of the container 6.
, 7' are fitted into the respective stopper fitting holes 10 on the lower end surfaces of the stoppers.

Reference numeral 5 denotes a blind hole having the same shape as the stopper fitting hole of the container corner fitting recessed in a predetermined position of each rail 20, and a set of four stoppers are fitted into the corner fittings 7, 7' at the four corners of the container 6'. 9 and 9' are fitted.

The top surface of the stopper 9 has a protrusion 8 which has the same shape as the stopper fitting hole of the container corner fitting and is fitted therein, and the bottom surface also has a protrusion 8.
protrusions 8' having the same shape as are respectively protruded, and the protrusions 8, 8' on the upper and lower surfaces respectively engage the stopper fitting hole 10 of the corner fitting;
It is configured to fit into the blind hole 5.

Next, the seeding order of containers will be explained.

As shown in Figure 1A, a container 6 suspended from a multi-purpose cargo ship straddles a pair of rails 2 laid on a hold bottom 1 that is wider on both sides than the width of the cargo ship. The protrusions 3 of each slider and the holes 1 of the container corner fittings (attached to the lower ends of the front, rear, left and right corners) 7 and 7' are mounted on the upper surfaces of the front, rear, left and right sliders 4 and 4'.
0 are fitted and supported, and the slider stopper 4 at the end of the rail
' is transported by a slider on a rail.

According to the figure, there is one container, but there may be more than one container.

...The next container 6' located in an area the size of Tsuchiro is placed in four blind holes 5 recessed at predetermined positions on the rail directly below Hashichiro so as to be adjacent to the preceding container 6. The corner fittings 7, 7 at the four corners are suspended from the upper surface of each stopper 9, 9' (four are provided in the front, rear, left, and right) fitted in advance.
' holes 10 are fitted with protrusions 8 on the upper surface of each stopper and are immediately fixed on the rail, adjoining the preceding container 6 and preventing the container 6 from moving along the rail.

Similarly, sliders 4 and 4 for the opposite side
The container placed on the ship is transported sideways, supported by the slider stopper 4'', and the next container is fitted and fixed to the stoppers 9 and 97 in the same manner as described above, and is placed on each pair of rails while being moved from the bow or stern. Multiple rows can be stacked sequentially from one direction to another.

To stack containers in several tiers, first place sliders 4.4' corresponding to the four corners of container 6 directly below the container.
... are placed opposite each other in advance, and the container 6 is placed stationary with the protrusion 3 and the stopper fitting hole 10 mating with each other, and for further stacking, stoppers 9, 9' are attached to the corner fittings at the four corners of the upper surface of the container 6. After repeating the operation of inserting the four corners of the overload container into the upper part of each container in order to accumulate the predetermined number of stages, the container is slid toward the side using a wire or other lift.

In this way, when the stowage in the area that spreads out laterally from the position directly below the hatch opening is completed, the stowage in the area directly below the hatch opening is completed by placing the stopper 9 corresponding to the four corners of the container on the blind hole 5 opened on the rail. In order to fit and further stack containers on top of the containers, stoppers 9 are interposed at the four corners of the opposing surfaces of the upper and lower containers in the same manner as described above, so that the desired number of stacks can be stacked.

In this way, since there is no need to adjust the loading position directly below the Tsuchiro, the lower loaded containers are placed on the rail via the stopper 9, so they are stabilized without moving in any direction.

Therefore, the container placed on the slider 4 is supported adjacent to the slider 4 and can be kept stable without collapsing against the shaking of the ship.

It goes without saying that many pairs of rails 2 are laid in the direction connecting the bow and stern of the ship in the hold.

As described above, the loading device of the present invention includes a simple rail 2 that is straight rod-shaped and has a predetermined number of blind holes 5 recessed in predetermined positions, and a slider with an upper protrusion 3 that slides astride the rail. 4,
4'... and a stopper 9 that fits into the blind hole 5.
By providing a multi-purpose cargo ship, a large number of containers can be easily, quickly, and reliably stowed in multiple rows and fixedly in the hold of a multi-purpose cargo ship by making effective use of the width of the hold bottom. This is a loading device that produces a pyramid effect even when moving up and down, without worrying about involuntary rocking or cargo collapse, and therefore having no adverse effects on the ship's belly.

In particular, the slider 4 of the device of the present invention is straddled over the rail 2,
The protrusions 3 are provided on the upper surface of the stopper 9 to prevent force from being concentrated on the protrusion portions of the slider 4 when the container is moved.
The shape of 8' is the same shape as the stopper fitting hole 10 of the container corner fitting, and the blind hole 5, which is recessed on the rail 2 and symmetrical to each other, is also the same shape as the stopper fitting hole 10 of the container corner fitting. Therefore, the stopper 9, the blind hole 5 of the rail 2, and the stopper fitting hole 10 of the container corner fitting fit together exactly, and the containers are stacked with good stability without swinging on the rail. .

Furthermore, the rails 2 used in the loading device of the present invention are two straight rod-shaped ones that immediately constitute a pair of rails, and one rail is composed of two space bars like the conventionally known rails. It is not as complicated as it used to be; it simply consists of two completely independent rails placed with their ends touching the ship's side without any fasteners or the like.

Therefore, it has the effect that it can be easily installed and removed from the bottom of the hold, and by providing the blind hole 5 corresponding to the container at a predetermined position of the straight rod-shaped rail, the stopper 9 can be fitted (just It has a simple and reliable structure that allows each container to be immediately fixed in sequence, and the structure of the stopper 9 is symmetrical with the top and bottom protrusions 8 and 8' preventing the concentrated load from being biased to one side (it is solid and can be used without being above or below). It is.

In the end, it is an excellent invention that is simple and reliable as a loading device.
When loading cargo other than containers, the slider is removed or assembled at the end of the rail, and the stopper is fitted into the blind hole 5, thereby making it possible to safely stow cargo without inadvertently slipping out.
