Description

[Detailed explanation of the idea] This invention relates to the bottom structure of a ship's hold.

In a bulk cargo ship equipped with a screw conveyor for unloading at the bottom of the ship, in order to make the most effective use of the cargo space, it is necessary to install a large number of hoppers at the bottom of the ship toward the inside of the ship.

In addition, as ships become larger, the hopper also becomes larger, which means that the length of the screw conveyor becomes longer and the load section on the screw conveyor becomes longer, which causes transportation problems and requires a large amount of power for the screw conveyor. .

Therefore, the present invention proposes a boat hold bottom structure that can solve the above problems, and one embodiment thereof will be described below based on the drawings.

1 is a bulk carrier for transporting powdered coal, etc., and there are a plurality of vessels (6 in this example) 2A and 2B in the bow and aft direction.

2C, 2D, 2E, 2F and has a central conveyor section 3 in the middle.

In the cross section of the ship 2A-2F, a plurality of (four in the example) bottom portions 6At6B, 6C, l are formed in the inboard direction by a plurality of (three in the example) center hoppers 4At4Bt4C and side hoppers SA, 5B. formed,
Further, each of the bottom portions 6A to 6D is formed into a wavy bottom hopper 7A, IB, and IC97D in longitudinal section.

Here, the wave pitch in the bow and stern direction is shifted by half a pitch between adjacent groups of port side ship bottoms 6A and 6B, and the structure is similar between the starboard side ship bottoms 6C and 6D.

Screw conveyors 8A, 8B, and 8Ct8D extending toward the inside of the ship are disposed at each wave bottom of the ship bottom parts 6A to 6D.

The screw conveyors 8B and 8C corresponding to the inner ship bottoms 6B and 6C are long ones, and their inner ends are supported by the central center hopper 4B, and their outer ends are connected to the spaces 9A in the side hoppers 5A and 5B. , 9B are supported by cases 10A and 10B.

Both screw conveyors 8B and 8C have penetrating portions 11A formed in both center hoppers 4A and 4C.

11B.

The screw conveyors 8A and 8D corresponding to the outer ship bottom parts 6A and 6D are short ones, and their inner ends are connected to the center hopper 4A at both ends.

4C, and its outer end is the case 10A.

Supported by 10B.

Each screw conveyor 8A to 8D has a case IOA, 1
Drive devices 12A, 12B, 12C, 12 attached to 0B
Each is driven separately by D.

In the cases 10A, 10B, chain conveyors 13A, 13B extending in the bow and stern directions are arranged, and the ends of these chain conveyors 13A, 13B reach the central conveyor section 3.

A packet conveyor 14 is provided within the central conveyor section 3, to which the chain conveyors 13A, 13B are connected at its reception opening.

A pair of packet conveyors 14 are provided on the bow side and the stern side, and penetrate through the upper deck 15, respectively, and have their discharge ports 16 located above the upper deck 15.

The starting end of 17 is the discharge port 1 of the packet conveyor 14.
6, and a rotating chain conveyor 18 that can be swung out of the ship is disposed at the end of the fixed chain conveyor.

: When taking out granular materials that have been loaded into ships 2A to 2F, first the screw conveyors 8A to 8D, chain conveyors 13A and 113B, and packet conveyor 14 of arbitrary ships 2A to 2F are driven.

Then, the powder and granules in any vessel 2A to 2F are transported to cases 10A and 10 by screw conveyors 8A to 8D.
B, and chain conveyors 13A, 13B
is carried out to the central conveyor section 3 side.

Next, the powder and granules are lifted onto the upper deck 15 by the packet conveyor 14, and passed from the discharge port 16 to the fixed chain conveyor 17, and then to the revolving conveyor 18.
transported by.

In the above-described operation, the screw conveyors 8A to 8D each act on one ship bottom 6A to 6D, and each of the ship bottoms 6
Since the load part (acting part) in A to 6D is short,
Conveyance can be performed even with small power drive devices 12A to 12D.

As described above, according to the present invention, by providing a large number of hoppers in the direction of the inside of the ship, the inside of the ship can be used most effectively.

In addition, the screw conveyor can be applied to one bottom of the ship to shorten its load section, and half of the load can be shortened, allowing for reliable transportation even with low power.
