Description

[Detailed Description of the Invention] This invention is mainly applicable to the loading of bulk cargo such as grains,
- This invention relates to a second deck device for a multi-purpose cargo ship that enables the loading of membrane materials.

If it is a bulk carrier, it is not possible to divide the hold into upper and lower parts, but when loading general cargo, it would be extremely uneconomical to divide the hold, excluding the area directly below the hatch, into upper and lower parts. In order to add a second deck, it would be sufficient to provide a second deck that is removable, but if the second deck is made removable, it is time-consuming and troublesome to attach and detach it, and it is difficult to securely fix it. Otherwise, there is a risk that the second deck will fall off.

By the way, when bulk cargo is put into a ship's hold, it accumulates in a conical shape.

This creates a gap in the upper side corner of the hold, but if the ship sails with this gap still in place.

This may cause the cargo to collapse, making it impossible to restore the hull.

Therefore, as a bulk cargo ship, if a slope plate is formed in the upper part of the hold to match the corner layer of the slope of the conical pile, that is, the rest angle peculiar to the cargo, and bulk cargo is loaded. In addition, it is necessary to make the ship a so-called cantilever ship, in which the cargo/bag is closely attached to the inclined plate so that there is no possibility of the cargo becoming slopped. Therefore, if the ship is a multi-purpose cargo ship suitable for both bulk cargo and general cargo, It is preferable that the second deck is used horizontally at a predetermined height, and when not in use, it is used as an inclined plate in the upper part of the hold of a cantilever ship, and if necessary, it is stored almost upright. It turns out.

Based on the above-mentioned viewpoint, this invention provides a second deck of a multi-purpose cargo ship in which the second deck can be fixed in three states: a horizontal state, an inclined state corresponding to the inclined plate of a cantilever ship, and an upright storage state. This provides a deck device in which a second deck panel is attached to a support member that can be freely moved in the upper F direction along an upright guide member that is attached to the inside wall of the bow, and a panel for the second deck is attached to the support member so that it can be rotated up and down. Stoppers for blocking upward movement are provided at predetermined positions above and below the guide member so as to protrude from each other, and sheaves are provided respectively at the support member and near the free end of the panel, while a required number of stoppers are fixed at predetermined positions in the upper part of the hold. A sheave is provided, and a wire rope, one end of which is fixed to the upper part of the inner wall of the tidying hold, is passed from the 7-p integral with the support member to one of the upper fixed sheaves, passed to the sheave near the free end of the panel, and then passed from the upper part to the sheave near the free end of the panel. It is unique in that it can be hoisted freely towards the upper deck via another fixed sheep.

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

FIG. 1 shows an embodiment of the apparatus of the present invention in a schematic cross-sectional view of the left center half of the ship's hull. As shown,
In the device of the present invention, a second deck panel 3, which is provided at a predetermined height position on the inner wall 2 of a hold 1 and can be raised and lowered, is placed in a horizontally collapsed state 1, which is shown by a solid line in the figure, directly below an upper deck 4. and a tilting state corresponding to the tilting plate of a cantilever ship.
The lower part of the side coaming 5A of the no-tsuchi 5, the upper deck 4, and the inner wall can be freely displaced between the upright state (■) along the inner wall 2, the formation of the second shell in the horizontally laid down state (I), and the lower part of the side coaming 5A of the no-tsuchi 5 in the inclined state (U). 2
This device enables the formation of a substantially triangular space S surrounded by front and rear transverse bulkheads (not shown).

FIG. 2 shows the device of the invention in a schematic front view;
A support member 7 that can be freely displaced in the vertical direction along a guide member 6 attached to an inner wall 2 of a hold 1.

The second deck panel 3 is installed so that it can be freely rotated up and down.

The guide members 6 are made of, for example, a channel, and a required number of guide members 6 are fixed in parallel with each other opening toward the inside of the hold 1.

In this embodiment, the support member 7 has a triangular plate shape and supports guide rollers 8 at upper and lower positions in the rear part so as to freely rotate, while the base of the flannel 3 (for the second deck) is pivotally attached to the front part, and the base part of the flannel 3 for the second deck is pivotally attached to the front part.
The guide members 6 are fixed to the inner wall 2 of the guide member 6 and can be freely moved in the vertical direction.

FIG. 3 is a large front view of the apparatus of the present invention with some of the main parts removed, and FIG. 4 is a perspective view of rice grains taken from FIG. The upper guide roller 8 supports a shaft portion 8A and a downwardly directed forked portion 9B of a connecting fitting 9 having upper and lower forked portions 9A and 9B.

On the other hand, a guide member 6 is attached to the upward forked portion 9A of the connecting fitting 9.
A sheep 10, which can be freely displaced in the vertical direction, is pivotally supported inside.

A bracket 11 is fixed to the front surface of the upper end of the guide member 6 so that the foot can support the base of the second deck panel 3 laid down horizontally in the lowered position.

The 7-pipe 10 has one end attached to a beam 12 above the inner wall 2.
The wire rope 13 fixed to the wire is passed over.

The wire rope 13 is connected to the beam 1 above the guide member 6.
The hook is passed to the fixed sheep 14 supported at a predetermined position of the second grade,
Further, the panel 3 is passed through a sheep 15 provided near the free end of the panel 3, and then passed to a fixed sheep 16 supported at a predetermined position on the beam 12 or the like.

Wire rope 1 leading to the upper deck via fixed sheep 16
3 is the winch on the upper deck via the fixed sheep 1'7 (
(not shown).

On the other hand, stoppers 18A and 18B are protruded from the front surface of the guide member 6 at predetermined positions above and below.

The stoppers 18A and 18B are both members for stopping upward displacement of the support member 7, and as shown in the enlarged front view in FIG. It moves and projects into the passage of the support member 7.

A suspension rod 21 that can be folded into two is attached between the free end of the panel 30 and the lower end of the side coaming 5A of No. Sochi. With the directional displacement, it bends in the direction of the arrow a, and (when the spring flannel 3 is in the water-spraying collapsed state) it develops into a straight knee shape (two-fold development, resisting the own weight and live load of the spring flannel 3).

The apparatus of this invention having the above-mentioned configuration is such that when the wire rope 13 (j) is wound up from the state shown by the solid line in FIG. The second deck nonel 3 stands up in the position shown in the figure, and is in the upright state as shown by ■ in Figure 1.

Further, when the wire rope 13 is wound up with the stopper 18B retracted and only the stopper 18A protruding, the support member 7 rises until it comes into contact with the stopper 18A, and then the free end side is pulled up, and as shown in FIG. The state is tilted as shown in .

Condition H above is for loading bulk cargo.

This is the displaced state of the panel 3 that makes the hold 1 look like a cantilever, as shown by the solid line in Figure 2, and the horizontally collapsed state shown by 1 in Figure 1 is the state in which the second deck is formed inside the hold L. It is.

As is clear from the above description, the device of the present invention can form a second deck by simply operating a wire rope and a stopper, depending on the type of cargo, and can also form a cantilever ship with a panel used for the second deck. It is a labor-saving device that can be remotely operated, as it can form a ceiling structure equivalent to an inclined plate, and if necessary, the second deck panel can be raised up to eliminate objects from entering the hold. It has excellent advantages, such as being extremely useful for improving the functionality of general-purpose cargo ships.
