Abstract

PURPOSE:To enable to carry and house containers even in holds under deck wing of an exclusive bulk carrier by a method wherein means for transferring containers to and from the position just under the hatch opening on the bottom floor ceiling of the hold are arranged on the bottom floor ceiling of the hold under the deck wing of the exclusive bulk carrier. CONSTITUTION:The container traversing devices, each of which consists of a piston 13, a cylinder 13A and the like, are arranged on the bottom floor ceiling of the hold under the deck wing part 5 of the exclusive bulk carrier 1. Containers 2 are housed in the holds just under the hatch opening 4 and as well as containers 2' are housed in the holds under the deck wing part 5. In case of landing containers, the containers 2 loaded in the holds just under the hatch opening 4 are directly landed from the hatch opening 4. After the finish of the landing of the containers 2, the containers 2' loaded in the holds under the deck wing part 5 of both sides are transferred to the position just under the hatch opening 4 by means of the traversing device and, after that, landed from the hatch opening 4. In such a manner as mentioned above, the exclusive bulk carrier can be utilized as a container ship.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cargo support and cross-transfer device in a ship's hold, which allows cargo such as containers to be stored in the ship's hold by stacking them high up to the lower part of the deck.

As shown in Figure 1, even if an attempt is made to transport cargo 2 such as containers by utilizing the empty time of the bulk carrier 1, there is only one relatively small container 4 installed in the hold 3. Therefore, the cargo 2 such as containers suspended in the hold 3 is 1
As shown by the solid line in the figure, the cargo 2' can only be loaded directly below the section 4, and is marked with an imaginary line.

Cargo to be stacked below deck 5 cannot be loaded because cargo handling is impossible.

However, it is uneconomical unless cargo 2 such as containers is loaded under the deck so as to fill the hold, and there is a risk that the cargo may collapse if it is loaded only in the center.

Based on the above-mentioned viewpoints, the present invention provides a cargo support and cross-transfer device in a cargo hold that can store cargo such as containers up to below the deck in a large cargo hold such as a bulk carrier.
A horizontally facing guide rail fixed on the floor of the hold, a cargo receiving bracket that can freely move horizontally along the guide rail, and a cargo receiving bracket that is dammed and rotated at a predetermined angle. It is characterized by having an eccentric axle that can be fixed in a moving position and an outer ring that is fitted around the eccentric part of the eccentric axle so that it can freely rotate.

Next, the apparatus of the present invention will be explained by way of embodiments with reference to the drawings.

FIG. 2 shows a front view of an embodiment of the device of the present invention, and also shows
Figure 3 (2) is an enlarged longitudinal section of the line ■-■ in Figure 2: IJi. The guide rails 7, identified as transverse, are groove rails having inward flanges 7A, 7A, and have a length spanning the entire width inside the hold 3, and are arranged in a predetermined number of rails in parallel.

The cargo receiving bracket 8 having seven outward flange SA and 8A inserted under the flanges 7A and 7A of the guide rail 7 has the width of the entire cargo 2' (see Fig. 1) loaded under the deck 5, i.e. The bottom surface is open and has a length corresponding to the width of the part that will be the bottom of the deck.

Inside the cargo receiving bracket 8, eccentric axles 9 are supported at multiple locations in the length direction.

The eccentric axle 9 has one of the shaft parts 9A, 9A supported on the front and rear walls 8B, 8B of the cargo receiving bracket 8 protruding outward, a lever 10 is attached to this, and a bearing 11 is attached to the eccentric shaft part 9B. The outer ring 12 is fitted through the outer ring 12 so that it can freely rotate.

The outer ring 12 rolls on a rail 7B provided within the guide rail 7.

On the other hand, a hydraulic cylinder 13 is installed on one side of the cargo receiving bracket 8.
The ends of the rods 13A are connected via a horizontal pin 14, and the hydraulic cylinder 13 has its base end connected to the floor 6 side with a horizontal pin 15.
It is attached via .

A container positioning cone insertion hole 16 is provided at a predetermined position on the top of the cargo receiving bracket 8.

The device of the present invention having the above-mentioned configuration rotates the eccentric axle 9 by operating the lever 1O and fixes it in a position where the long diameter side of the eccentric shaft portion 9B faces downward, and the rod 1 of the 7I#l pressure cylinder 13
3A, the cargo receiving bracket 8 is placed directly under the hatch 4, and the containers are stacked on top of the cargo receiving bracket 8.

What is the height of containers stacked on the cargo receiving bracket 8?

As shown in Figure 1, the maximum height that can be stacked under the deck is set.

The cargo receiving bracket 8 that has completed cargo stacking is moved to the hydraulic cylinder 1.
After moving the rod 13A in the direction of the deck by protruding the rod 13A of No. 3 and transporting the cargo from the position directly below the hatch 4 to the bottom of the deck, the eccentric shaft 9 is moved 180' by operating the lever 1O.
By rotating and placing the short diameter side of the eccentric shaft portion 9B downward, the cargo receiving bracket 8 is lowered and the seven flange 8A, 8A is brought into contact with the bottom of the guide rail 7.

After storing the cargo using the cargo receiving brackets 8 placed in the same way under the left and right decks,
Cargo 2, which is indicated by a solid line in the figure, is suspended and piled up.

When taking out the cargo 2 from the hold 3, the above procedure is reversed.

In addition, when loading the cargo 2' directly under the hatch 4 after storing the cargo 2' under the deck, appropriate pillows (not shown) are placed on the floor 6 so that the cargo does not interfere with the hydraulic cylinder 13. put. In this case, the pillow material is a flange with the short diameter side of the eccentric shaft portion 9B facing down.

8A is set at a height equal to the height of the cargo receiving bracket 8 in a state where it is in contact with the bottom of the guide rail 7.

As is clear from the above description, the device of the present invention is an excellent device that can extremely easily store containers in the lower part of the deck in the hold of a bulk carrier, making it possible to use the bulk carrier for multiple purposes. It has advantages.
