Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a corner material for cargo hold mouths on a top deck, which is extended into the cargo hold mouths of ships carrying bulk cargoes, particularly ships carrying bulked cereals. The present invention relates to a swash plate that is fixedly installed in a part to prevent the accumulation of bulk cargo such as grains.

2. Description of the Related Art Conventionally, as a swash plate for preventing accumulation of bulk cargo of this kind, as shown in FIGS. 3 to 4, in order to avoid stress concentration on the edge member 23 in the cargo hold, An edge portion of the upper deck 22 is extended in a triangular shape having an arcuate bottom side, and is obliquely upward from an edge portion of the extending triangular upper deck 22 toward a corner portion of the warehouse lip 23. On swash plate 2
4 and the side portions 25 of the swash plate are fixed to
It is known that the lower part 26 is fixedly mounted at No. 3 and the lower part 26 is free.

[0003]

In the former of those described in the prior art, the cargo hold mouth is deformed by repeated voyages of loading bulk cargo and empty cargo, and the cargo hold mouth is deformed. The upper deck 22 and the swash plate 24 cannot be absorbed by the swash plate 24.
A crack is generated in the welded part of the, and the crack grows, and a bulk cargo such as cereals enters the space formed by the upper deck 22, the swash plate 24, and the edge member 23 of the warehouse from the crack, and accumulates and accumulates. Then, there is a problem in that the cargo is mixed with the bulk cargo as the back load, and the cargo is contaminated, and the commercial value of the bulk cargo as the back load is reduced.

In the latter case, since the upper deck 22 and the swash plate 24 are not fixed to each other and are free, no cracks occur between the upper deck 22 and the swash plate 24, but the swash plate is not formed. Two
Since the bottom side of 3 is merely placed on the upper deck 22, bulk cargo such as cereals is formed from the gap between the swash plate 24 and the upper deck 22 by the upper deck 22, the edge member 23 and the swash plate 24. There is a problem that the same phenomenon as in the former case occurs by invading and staying in the space.

The present invention has been made in view of the above problems of the prior art, and the purpose thereof is to generate a crack between the upper deck and the swash plate extending inside the cargo hold mouth. No, it is the corner portion of the Kuraguchi edge material on the upper deck,
Provide a swash plate for preventing bulk cargo accumulation that prevents bulk cargo such as cereals from entering the space formed by the upper deck, the edge material of the kuraguchi and the swash plate, and therefore does not cause cargo pollution to the post cargo Is what you are trying to do.

[0006]

In order to achieve the above object, the swash plate for preventing bulk cargo accumulation in this invention is
An elastic body that abuts a notched arc-shaped base that forms a substantially isosceles triangle that extends in the corner portion of the cargo hold edge member in the cargo hold; and a sandwich plate and a swash plate that sandwich the elastic body, The elastic body sandwiched by the swash plate and the sandwich plate is brought into contact with the upper deck extending into the cargo hold mouth, and the other two sides except the notched arc-shaped bottom side of the swash plate are
It is fixed to the kuraguchi edge material with an upward slope of about 45 degrees toward the corner portion of the kuraguchi edge material.

[0007]

The elastic body prevents the deformation of the swash plate from being transmitted to the upper deck, and prevents the bulk cargo from entering the space formed by the upper deck, the edge member of the opening and the swash plate.

[0008]

EXAMPLES Examples will be described with reference to the drawings.
1 and 2, in the cargo hold of a bulk carrier,
In accordance with the notched arc of the edge portion of the extending upper deck 1, the notched arc-shaped base of the substantially isosceles triangular swash plate 3 having a notched arc-shaped base is bent and abutted against the bent end.
An arcuate steel sandwich plate 5 having the same rotation center as the notched arc is welded.

An elastic body 4, for example, an elastic body 4 made of synthetic rubber is embedded in a recessed portion formed by the swash plate 3 and the sandwiching plate 5.

The elastic body 4 is brought into contact with the notched arc-shaped edge portion of the upper deck 1, and the other two sides of the swash plate 3 other than the bottom side are made into a corner portion of the Kuraguchi edge member 2 at an angle of about 45 degrees. It is welded to the Kuraguchi edge material 2 with an upward slope.

[0011]

Since the present invention is constructed as described above, it has the following effects.

Since the edge portion of the upper deck and the swash plate are in contact with each other through the elastic body, the deformation of the cargo hold is absorbed by the elastic body and is not transmitted to the swash plate, and cracks occur at the location. Prevent from occurring.

The elastic body prevents the bulk cargo such as cereals from entering the space formed by the upper deck, the edge member of the hood and the swash plate, and does not cause the cargo cargo of the rear load to be contaminated.

The mounting angle of the swash plate is approximately 45 degrees from the corner portion of the edge material of the kuraguchi and inclines downward toward the inside of the kuraguchi. Will fall into the cargo hold without any accumulation.

Claims (1)

(57) [Scope of utility model registration request] 1. A swash plate for preventing accumulation of bulk cargo, which is fixed to a corner portion of the edge material of the cargo mouth of a cargo hold of a bulk cargo ship, and is provided at the corner portion of the cargo edge inside the cargo hold. It is composed of an elastic body that abuts the notched arc-shaped bottom of the upper deck that extends in an isosceles triangular shape, a sandwiching plate that sandwiches and holds the elastic body, and a swash plate. The swash plate caused by stress concentration due to deformation of the hull by abutting the sandwiching elastic body on the upper deck extending inside the cargo hold mouth and welding the other two sides except the bottom of the swash plate to the cargo hold edge material A swash plate for preventing bulk cargo accumulation, which is characterized by preventing cracks in the cargo.
