Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hold structure of a bulk carrier that carries bulk goods such as ores, coal, grains, and wood chips.

[0002]

2. Description of the Related Art Conventionally, bulk carriers for carrying bulk goods such as ores, coal, grains and wood chips have been known.

As shown in FIG. 5 (a perspective view of a cross section of a hull), a ship carrier structure of a bulk carrier has an upper inclined wall inside a hull formed of a top deck 1, a side shell 2 and a bottom shell 3. Topside tanks 5 with bottom plates 4 on both sides of the hull
And a double bottom 9 having a lower sloping wall 6 as a top plate and hopper tanks 7 and inner bottom plates 8 provided on both sides of the hull as a top plate, and a horizontal bulkhead 11 having a corrugated longitudinal direction of the hull.
It is divided by to form a boat hold. In addition, 12 is a lower stool fixed to support the horizontal bulkhead 11, and 13 is an upper stool similarly provided below the upper deck 1.

The inclined wall 4 of the topside tank 5 is
In order to restrict the movement of the bulk cargo due to the rolling of the hull, the bulk is formed so as to be inclined toward the barb edge 10 so that the free surface of the upper portion, which is the largest, is reduced.

FIG. 6 is a part of a horizontal sectional view taken along the horizontal bulkhead 11 in FIG. 5, in which the horizontal bulkhead 11 is fixed to both sides of the horizontal bulkhead 11 in addition to the upper and lower ends. 2 '・
・ Is a frame on the ship side.

As the horizontal partition wall 11, a corrugated structure in which a plurality of plate members are welded is often used.

By the way, in the bulk carrier, the corners between the horizontal bulkhead 11 and the stool 12 and the horizontal bulkhead 1
There is a problem that it is difficult to scratch the cargo in the corner B between the ship 1 and the outer shell 2 of the ship.

As a means for solving the problem of freight accumulation at the corners of the horizontal bulkhead 11 and the stool 12 as a means for solving the problem
No. 2-165191 is disclosed, and the invention is to provide a slant plate at a corner portion a between the horizontal partition wall 11 and the stool 12 to prevent cargo accumulation.

[0009]

However, the cargo is accumulated by the corrugated transverse bulkhead 11 and the stool 1 described above.
There is a problem that cargo is accumulated not only in the corners with the corners 2 but also in the corners b, which are the four corners of the ship's side plate 2 and the corrugated transverse bulkheads 11, which are the four corners.

Normally, an ore ship and a coal carrier are
Bringing a bulltozer into the ship hold and collecting cargo in the center of the ship hold,
It is landed by a bucket of an unloader on land, but in the excavator of a bulltoza, the corner B is a narrow place and it is difficult to scrape it. Further, at a high position near the topside tank 5, it is impossible to scrape it with a bulltozer, so the cargo is currently being manually collapsed by the cargo worker.

Also, in a bulk carrier for grain and wood chips, cargo is piled up in the corners as well, and it is difficult to scrape the cargo.

As described above, in the conventional boat-carrying structure, the cargo handling efficiency is poor, and a measure for preventing cargo from being jammed in the corner B has been desired.

[0013]

[Means for Solving the Problems] A first means for solving the above-mentioned problems is to provide plates at the corners of the four corners formed by the contact between the side plate of the ship and the transverse bulkhead, and to provide the said corner and the ship's barge. This is a cargo hold structure of a bulk cargo ship that separates and from each other to prevent cargo from being jammed. The plate eliminates the corners of the ship's four corners and prevents cargo from being jammed.

The second means for solving the above-mentioned problems is a structure for carrying a bulk carrier in which a passage means is formed in a section formed by a side plate, a transverse bulkhead and a plate.

In addition to preventing cargo from being jammed, the passage means in the compartment is isolated from the boat, so that the accumulation of cargo does not hinder passage to the boat.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. The same parts as in the prior art will be described using the same reference numerals.
The bulk carrier of the present invention has a single-hull structure and is called a ship-side outer plate, and a double-hull structure is called a ship-side inner plate and both are collectively called a ship-side plate.

FIG. 1 is a perspective view showing a ship carrier structure of a bulk carrier according to the present invention. The corners B between the transverse bulkhead 11 and the ship side outer plate 2 are eliminated by a plate 14, and the plates 14 are provided at four corners of the ship carrier. The side surface is provided on the side plate 2 and the lateral bulkhead 11,
The upper portion is joined to the inclined wall 4 of the topside tank 5 and the inclined wall 13a of the upper stool 13, and the lower portion is inclined wall 6 of the hopper tank 7 and the inclined wall 12a of the lower stool 12.
To be part of the hull structure.

FIG. 2 is a part of a horizontal sectional view of the horizontal bulkhead 11 in FIG. 1, in which the plate 14 is bifurcated from the side of the horizontal bulkhead 11 at a predetermined inclination angle with respect to the outer shell 2 of the ship. It is joined.

A stiffener 14 'is attached to the back surface of the plate 14 to provide rigidity. FIG. 3 is a cross-sectional perspective view in which a part of the boat carrier structure of the present invention is enlarged. Horizontal bulkhead 11 and outer shell 2
Are joined to each other via a plate 14, and the plate 14 is bifurcated from both sides of the horizontal partition wall 11 and joined to the ship side outer plate 2 at a predetermined inclination angle. Further, the lower part of the plate 14 has a hopper tank 7 and a lower stool 1.
2, and the upper portion is joined to the top side tank 5 and the upper stool 13.

Further, the structure formed by the plates 14 and 14 and the ship side outer plate 2 functions as a strength member of the ship body.

Further, the plates 14 and 14 and the ship-side outer plate 2
In addition to functioning as a ballast tank, the section 15 formed by and can also form a passage means from the upper deck to the ship's barge inside.

The joint structure of the lateral bulkhead 11 with the plate 14 and the ship side outer plate 2 may have various design structures depending on the size of the hull, but in the present invention, the plate is used to eliminate the corner portion B. The gist is to arrange 14 at the four corners of the boat.

FIG. 4 is a partially enlarged cross-sectional perspective view of the boat-carrying structure of the present invention, in which the passage means 16 is installed in the section 15 formed by the plates 14 and 14 and the ship-side outer plate 2. is there.

A spiral staircase 16b is installed on a column 16a extending from the upper deck 1 to the inner bottom plate 8 of the boat, and the hopper tank 7 and the inclined walls 6, 12 'of the lower stool 12 are further installed.
Further, watertight type opening / closing doors 6'and 12b are provided respectively to secure a passageway between the upper deck and the boat.

Although the present invention has been described with respect to the carrier structure of a bulk carrier having a single-hull structure having one outer shell plate, the same effect can be obtained when applied to the carrier structure of a double-hull structure. In that case, the outer shell of the ship is changed to the expression of the inner shell of the ship, and the others are not changed.

[0026]

Since the present invention is as described above, the plates are provided at the four corners of the boat and the corners are eliminated, so that cargo may be accumulated in the corners and cause jamming. Since there is no such cargo, there is an advantage that the cargo handling efficiency of cargo within the cargo is significantly improved.

Further, since the passage means is provided in the section formed by the plate, the side plate and the lateral bulkhead, it is possible to secure the access to the inside of the boat.
