Abstract

PURPOSE:To permit to load bulk cargo and motorcars or the like simultaneously by a method wherein the hatch cover of a bulk carrier is provided with the elevating deck fixed to the lower part thereof through hanging ropes with predetermined intervals to lift up the hatch cover together with the elevating deck. CONSTITUTION:The hanging ropes 7 are hang at the lower part of the hatch cover 4 for the bulk carrier and the elevating decks 3 are fixed to the hanging ropes 7 with predetermined intervals. The elevating decks 3 are permitted to lift up and install together with the hatch cover 4. According to this method, the bulk cargo 5 and the motorcars 9 may be loaded at the same time and the loading efficiency of the ship may be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hatch lid in which an elevating deck for transporting automobiles is integrally suspended from a lower part of the hatch lid with a sling cable at a distance.

In recent years, the export of automobiles from Japan to overseas has been increasing, and many car carriers have been built.However, in the case of such specialized vessels, various spaces are required when loading other cargo on the return trip to Japan. subject to the above restrictions.

On the other hand, with conventional bulk carriers, it is only necessary to load bulk cargo in the hold and load containerboard (1) and wood on the top of the hatch lid. It was impossible to do so.

Additionally, if a deck for loading automobiles is fixedly installed in a part of the hold of a bulk carrier, the deck becomes a dead space when no automobiles are loaded, reducing the cargo loading efficiency of the cargo vessel. be.

The present invention aims to solve the above-mentioned drawbacks of the conventional bulk carrier, and the present invention has a structure in which a sling is hung from the lower part of the hatch cover of the bulk carrier, and the sling is used to raise and lower the vessel at predetermined intervals. This cargo hatch lid is characterized in that the deck is fixed and the elevating deck can be lifted together with the cargo hatch lid.

Next, the present invention will be described in detail with reference to the drawings.

Figure 1 shows the left half of a bulk carrier 1, in which an elevating deck 3 for loading automobiles is suspended in multiple stages from the lower part of a hatch lid 4 using hanging ropes 7 in a hold 2, and (2) the lowest stage. Bulk cargo 5 is loaded on the lower part of the elevating deck 3.

Figure 2 shows the right half of the bulk carrier 1, in which elevating decks 3 are stacked in multiple stages on the lower surface of the hatch lid 4 that closes the opening of the hold 2, and the lowermost elevating deck 3 has a packaged cargo 6. It shows the state in which it is accommodated.

FIG. 3 shows the movement of the hatch lid 4 and the lifting deck 3, and shows a state in which the lifting deck 3 is suspended by a hanging rope 7 with a constant interval provided on the lower surface of the hatch lid 4.

The hatch cover 4, the elevating deck 3, and the suspension cable 7 are integrated, and as shown in Figures 3 and 4, they are lifted up by the ship's cargo handling equipment or port cargo handling equipment (crane, etc.) and transported to other holds. It is placed on the palate 4.

In the hatch lid according to the present invention, the elevating deck 3 is connected in advance to the lower part of the hatch lid 4 that closes the opening at the upper part of the ship's hold 2 at a certain interval by means of suspension ropes 7, and this connected body is placed on another hatch cover 4 using cargo handling equipment such as a crane (3), and as shown in Fig. By lifting the cargo hold 2, bulk cargo 5 and automobiles 9 can be stored alternately or simultaneously.

Furthermore, as shown in FIG. 2, it is possible to load packed cargo 6 inside the hold 2 and stack the elevating deck 3 and hatch cover 4 on top of the packed cargo 6 in the uppermost stage.

Therefore, according to the present invention, (a) Bulk cargo 5 and automobiles 9 can be stored in the hold 2 alternately or in the same ship. (Fig. 1) (b) Packed cargo 6 can be stored inside the hold 2.

In this case, the elevating deck 3 can be placed below the hatch lid 4 and above the packaged cargo 6. (Fig. 2) (c) As mentioned above, in the hatch lid according to the present invention, the lifting deck 3 can be suspended by the hanging ropes 7 at a certain interval between the hatch lid 4 and its lower part. Therefore, as shown in FIG. 3, the assembly including the hatch cover 4 and the like can be easily lifted.

Furthermore, by independently hoisting the suspended cable from above the hatch lid, the first FI! As shown on the right side of J, there is a large effective space on the bottom surface, making it possible to remove and load packed cargo, etc.
Automated operators can also load by suspending the elevating deck.
