DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cargo handling method and a ship for improving cargo handling of cargo such as containers.

[0002]

2. Description of the Related Art As shown in FIG. 6, a ship 3 having cargoes 2 such as containers, bulk goods, etc. loaded in a cargo hold 1 uses a crane 5 installed on a quay 4 for several ships. Cargo 2
Is lifted up and off at a predetermined position on the wharf 4. In addition, the cargoes 2 stacked on the wharf 4 are also lifted by the crane 5 several by one and loaded into the cargo hold 1. In some cases, the crane is installed on a ship.

[0003]

However, the conventional cargo handling operation using a crane requires a very large amount of time for cargo handling because there is a limit on the amount of cargo to be loaded at one time. Therefore, it is necessary to make the ship moored at the wharf for a long time until the cargo handling work is completed,
At the present time, it has affected the cargo handling schedule of other ships and has had a significant effect on the entire shipping schedule of the ships.

[0004] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a ship handling method and a ship capable of greatly shortening the cargo handling time.

[0005]

According to the first aspect of the present invention, a ship in which a cargo hold having a large number of containers and the like loaded thereon is loaded in a hull is placed sideways on a quay, and Cargo from both sides in the width direction of the
A quay set at the same horizontal level as the bottom of the side wall of the warehouse
This is a cargo handling method for a ship, characterized in that a cargo storage warehouse is horizontally moved toward a cargo landing section of a head to perform loading / unloading or loading of the cargo storage warehouse.

According to a second aspect of the present invention, a hull provided with an opening in the side wall of the hull to provide a cargo space communicating in the width direction and a cargo such as a large number of containers are collectively mounted inside the hull. And a cargo hold to be loaded into the cargo space, and the cargo hold has a watertight structure that prevents seawater from entering the interior, and a side wall in a width direction has a side wall shape that becomes a part of the hull side wall. together are formed, at least the side walls and bottom surface of the cargo storage hold, the slide mechanism is provided for moving itself to the width direction of the hull, the
The horizontal level is set to be almost the same as the bottom of the cargo hold side wall.
The cargo hold is horizontal to the cargo landing at the open wharf.
A vessel characterized by being configured to move .

[0007]

According to the present invention, the cargo storage space is slid horizontally from both sides in the width direction of the hull, that is, from the side wall side of the hull, so that a large number of containers and other cargoes are collectively discharged at the cargo landing section of the pier. Since cargo can be unloaded or loaded onto the hull from the cargo landing section, the time required for cargo handling can be significantly reduced. Further, since it is not necessary to make the ship moored at the wharf for a long period of time, it does not affect the schedule of cargo handling work of other ships.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a plan view showing a ship 8 laid sideways on a pier 7, and FIG. 2 is a side view of the ship 8.

A ship 8 having a bow 8a and a stern 8b has a ship body 9 loaded with cargo storage shelves 10 which are kept watertight.

That is, as shown in FIGS. 1 and 2, the hull 9 is provided with partition walls 9a, 9a in the width direction thereof to form a plurality of cargo spaces 9b, and a hull side wall 9c. , 9d are provided with a plurality of rectangular openings 9e, 9
f, 9 g are formed. Thereby, each cargo space 9
b has a structure communicating with the hull 9 in the width direction.

On the other hand, the cargo storage warehouse 10 is formed in a box shape in which cargoes such as a large number of containers are collectively mounted therein and seawater is prevented from entering the interior. And
A slide mechanism 11 is disposed on the side wall 10a and the bottom face 10b of the cargo storage warehouse 10, and the slide mechanism 11
Is composed of a roller 11a that rolls on a side wall and a bottom surface defining a cargo space 9b, and a roller support member 11b attached to the side wall 10a and the bottom surface 10b so as to rotatably support the roller 11a. Have been. A drive device (not shown) is connected to the slide mechanism 11 disposed on the bottom surface 10b, and the rollers 11a automatically roll by remote control or the like. This allows
The cargo hold 10 is movable in the width direction of the hull 9.

Here, the side wall 1 in the width direction of the cargo storage warehouse 10
As shown in FIG. 5, when the cargo storage shelves 10 are loaded into the cargo spaces 9b, the hull side walls 9c and 9d are turned off.
It is formed in a ship's flank shape to be a part of d. Also, as shown in FIG.
A fairing 12 for reducing the fluid resistance of the side wall of the hull during voyage is provided on the outer peripheral edge of 10c.

Next, a cargo handling method using the ship of the above embodiment will be described with reference to FIGS.

When the ship 8 is laid on the wharf 7, the horizontal level is set to be substantially the same as the bottom of the openings 9e, 9f, 9g (side walls 10c, 10d of the cargo storage 10) of the hull side walls. Cargo landing units 7a and 7b are constructed. The bottoms of the cargo landing sections 7a and 7b are flooded.

First, the cargo storage warehouse 10A loaded on the hull 9 is moved in the cargo space 9b by the slide mechanism 1A.
1 and slide it toward the cargo landing section 7a. Then, after the slide mechanism 11 on the bottom surface 10b is brought into contact with the cargo landing portion 7a, the cargo storage warehouse 10A is unloaded onto the cargo landing portion 7a by further sliding. Here, when the cargo storage hold 10A is loaded and unloaded on the cargo landing part 7a, the hull 9 may rise due to an increase in buoyancy and hinder the cargo handling work. At the same time as the loading / unloading work, the cargo storage 1
By loading 0A 'into the cargo space 9b, the hull 9 does not rise and there is no risk of impairing the cargo handling operation.
Further, the other cargo storage bins 10 loaded on the hull 9
B and 10C are also loaded and unloaded to the cargo landing section 7a by the same procedure.

Therefore, in this embodiment, the hull 9
By sliding the cargo storage shelves 10 horizontally from both sides in the width direction, that is, from the side of the hull side walls 9c, 9d, cargoes such as a large number of containers are collectively loaded and unloaded onto the cargo landing portions 7a, 7b, Or cargo unloading section 7
Since cargo can be loaded from a and 7b to the hull 9, the cargo handling time can be greatly reduced. Further, since it is not necessary to make the ship 9 having landed the cargo storage bins 10 stay at the wharf for a long time, it does not affect the schedule of the cargo handling work of other ships.

[0017]

As described above, according to the present invention, cargoes such as a large number of containers are collectively moved by sliding the cargo storage horizontally from both sides of the hull in the width direction, that is, from the side of the hull. Cargo can be unloaded to or from the cargo unloading section, or loaded onto the hull from the cargo unloading section, greatly shortening the cargo handling time. Since there is no need to carry out such operations, the schedule of cargo handling work of other ships is not affected. Therefore, compared with the conventional cargo handling work using cranes installed on piers and ships, the cargo handling time of cargo such as containers can be significantly reduced, and the efficiency of shipping operations can be greatly improved. it can.
