Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cargo handling system in a place without port facilities and a ship used therein.

Cargo handling operations are extremely difficult in locations with poor or no port facilities, and there are regions where many ships wait offshore waiting for preceding ships to unload their cargo.

Cargo handling work in places like this where port facilities are insufficient or not available at all is conventionally carried out by anchoring a mother ship that can carry a large number of purges loaded with cargo off the coast of the cargo handling area, and then distributing purges from this mother ship onto a sandy beach or the like. This method speeds up the work until the purge is unloaded from the mother ship to the sea; In order to raise it, quayside equipment such as a crane is required, so overall it is not a very efficient method.

As a result, many ships are forced to wait offshore.

In addition, there are so-called roll-off/roll-on ships that are designed to allow trailers and the like to enter and exit directly as ships that meet this purpose, but this is not a good idea as it has poor volumetric efficiency.

The present invention has been made in view of these points, and it is an object of the present invention to propose a cargo handling system and a ship used therein, which can efficiently carry out cargo handling work even on sandy beaches where there are no port facilities, and at the same time make advantageous use of existing ships. .

Examples thereof will be described below based on the drawings.

In Figure 1, 1 is a sandy beach with no port facilities where cargo handling work is carried out, 2 is a mother ship anchored offshore of this sandy beach 1, 3 is cargo such as containers loaded on mother ship 2, and 4 is a temporary beach on sandy beach 1. A barge for forming a bridge, 5 a cargo boat that can dock on the temporary bridge, 6 the barge 4 and the cargo boat 5.
Crane equipment for floating on the sea or storing on the mother ship 2, 7
numeral 8 represents a road, and numeral 9 represents a trailer.

The barge 4 is an empty vessel similar to a normal landing craft, and has a bow door 12 and a stern door 15.

Reference numeral 11 denotes a hinge mechanism for opening and closing the bow door 12. The bow door 12 is closed during navigation from the mother ship 2 to the beach 1, and is fully opened outward via the hinge 11 after landing on the beach 1 as shown in FIG. Thereafter, at the same time, the connecting bridge 14 provided via the hinge 13 is rotated from the stored state (imaginary line) toward the beach 1 side, thereby connecting the floor 16 inside the barge 4 and the beach 1.

On the other hand, the stern door 15 is configured to be openable and closable via the hinge 10, and is fully opened (solid line) when the ship touches the bottom, in preparation for the cargo boat 5 to be described later to come ashore.

17 is an engine, 18 is a screw, and by having such a propulsion equipment, it is possible to navigate by self-sawing, and although not shown, it has a rope winding device for lifting and lowering the anchor,
As is clear from FIG. 1, by winding up the winding device after the cargo handling operation is completed, the bottomed state is released and the ship can easily return to the mother ship 2.

Further, it is advantageous that the communication bridge 14 is a pair of left and right communication bridges 14a and 14b arranged to maintain the wheel width of the trailer 9 through which the trailer 9 can pass.

The cargo boat 5 has a bow door 21, as shown in FIGS.
It has a floor 19 continuous to the bow door 21, propulsion equipment consisting of an engine 25 and a screw 26, and a holding device 20 for holding the container 3 at an appropriate height.

The bow door 21 is normally closed, and after the aforementioned barge 4 lands on the bottom and forms a temporary bridge, the bow is moored to the stern of the temporary bridge (barge) 4, and the bow door 21 is closed to the barge. The barge 4 is placed open on the stern door 15 (in an open state), and the floor 16 of the barge 4 and the floor 19 of the cargo boat 5 are connected.

In addition, a cushioning material 22 is installed at the bow of the ship to avoid the impact when docking.
a is arranged.

Further, in this cargo boat 5, a cargo holding device 20 for holding a container 3 or the like supported by a link mechanism 23 is provided on the side wall 22 of the cargo compartment.
The link mechanism 23 has a floor portion 19.
It is driven by a cylinder 24 installed between.

23A has an upper part that is bent outward and a key part 23 at the lower part.
This is a container holding link that has a and constitutes one link of the link mechanism 23.

The interval between the holding links 23A can be adjusted as desired depending on the size of the container 3 by moving the cylinder 24 in and out, while maintaining the same posture relationship.

And there is always a trailer 9 between the Con Ana 3 and the floor 19.
It has a gap through which the container 3 can enter, and also has a device for transferring or transferring the container 3 between the holding device 20 and the trailer 9.

Note that 19a is a guide that regulates the course of the trailer 9, and the entrance (bow) side of the trailer 9 is a wide portion 19b.

The barge 4 and cargo boat 5 described above can be loaded in the storage section 27 provided on the stern side of the mother ship 2.

As shown in FIGS. 7 and 8, this storage section 21 is provided adjacent to the living area 2A, and an opening/closing door 28 is attached to the rear part of the floor section 27a of the storage section 21 via a hinge mechanism 28a. After the mother ship 2 was anchored offshore, this opening/closing door 2
8 is fully opened as shown in the figure, and the barge 4 and cargo boats 5A to 5D are sequentially lowered by crane equipment through the opening formed at that time and floated on the sea, after which they navigate under their own blades according to their respective roles.

The crane equipment 6 is normally similar to an overhead crane used in a factory, etc., and runs along a rail 29 disposed between the support column 29a and the living area 2A, and is attached to a barge. It consists of a moving frame 32 having means for winding in and feeding out a wire 30 to which a holder 31 such as No. 4 is connected.

In addition, this storage section 21 includes barges 4, cargo boats 1-5A~
A protective guide and the like are provided when moving the 5D.

On the other hand, a cargo loading section 33 such as a container is provided on the bow side of the mother ship 2.

The cargo (container) 3 loaded on this loading section 33 is transferred to the cargo boat 5 on the sea by an attached loading/unloading means 34.
loaded on top.

This loading/unloading means 34 consists of a frame 36 that runs in the longitudinal direction of the mother ship 2 via wheels 35, and a main body (not shown) that can run in a direction orthogonal to the running direction of the frame 36. This makes it possible to transport all the containers 3 in the storage section 33.

Furthermore, it is necessary that the mother ship 2 is equipped with a forklift, a trailer, etc. as necessary; however, this may be omitted depending on the land facilities of the destination.

The loading procedure will be explained below with reference to FIGS. 1 and 10.

In the following explanation, the procedure for unloading a container to a destination will be explained, but the procedure for loading a container onto a mother ship can be carried out in the reverse order.

First, the mother ship 2 is anchored off the coast of the sandy beach 1 where there are no port facilities at the destination, and the stern door 28 of the mother ship 2 is fully opened.
The barge 4 is floated on the sea from the storage section 27 using the crane equipment 6, the barge 4 is sailed toward the beach 1, and the anchor is lowered in front of the beach. Open and release the door 12 and the stern door 15,
At the same time, the connecting bridge 14 is rotated and installed on the sandy beach 1 to form a temporary bridge.

Next, the cargo boats 5A to 5D are sequentially unloaded onto the sea from the mother ship 2, moved below the loading/unloading means 7 of the mother ship 2, and a predetermined number of containers 3 are loaded onto the cargo boat 5 by the loading/unloading means 7.

At this time, if there are no forklifts, trailers, cranes, etc. as necessary land facilities, then the cargo boat will start) 5A
These facilities will be unloaded in advance using a

The cargo boat 5B loaded with the container 3 sails toward the temporary bridge, and when it arrives at the temporary bridge, its bow hits the stern of the temporary bridge (barge) 4, the bow door 21 is opened, and the trailer 9 Create a passageway for entry.

At this time, the subsequent cargo boats 15c and 5D are
Like -5B, it is proceeding to load Container 3 or to the temporary bridge.

In addition, cargo boats transported by forklifts, etc.) 5
A returns to mother ship 2.

When the cargo boat 5 docks at the temporary bridge as described above, the trailer 9 is inserted into the lower part of the container 3, and the cargo boat 5 is transferred onto the trailer 9 as appropriate, and then transported toward the destination.

By repeating this procedure, landing work can be carried out efficiently.

In addition, when loading containers, etc., the reverse is true, and furthermore, after landing, the cargo boat 5 and barge 4 are stored inside the mother ship 2, but the barge 4 is attached to the anchor and the barge 4.
By winding up the cable that connects the ship, it is possible to easily leave the sandy beach 1 and shift to self-sawing navigation.

As is clear from the above explanation, the method according to the present invention and the ships used therein can carry out cargo handling work efficiently even on sandy beaches where there are no port facilities, eliminating the need for waiting offshore as in the past, and improving economic efficiency. It is also excellent.

In addition, it goes without saying that cargo handling operations can be carried out as usual in areas where port facilities are sufficiently developed.
