Description

[Detailed Description of the Invention] The present invention relates to an inboard structure equipped with a rampway that connects upper and lower decks.

Many ro-ro ships and vehicle carriers are equipped with several decks, and for example, as shown in FIG. 1, an upper deck 1 and a lower deck 2 are connected by a rampway 3. In addition, 26 is a quay.

Conventionally, the inboard structure around the rampway 3 was as shown in FIGS. 2 and 3, for example.

A substantially rectangular deck opening 4 is provided in the upper deck 1, and a rampway 3 that connects to the lower deck 2 from the deck opening edge 5 is provided in an inclined manner. Further, a lamp cover 6 is provided in the deck opening 4, and the end thereof is connected to the deck opening edge 7.
The opening is connected to the opening by a hinge, and can be rotated upward via a pulling wire 9 to open. The lamp cover 6 is configured to be flush with the upper deck 1 in the closed state, so that the deck opening 4 becomes a loading area.

By the way, in order to increase the safety of the ship when it is flooded, it is originally necessary to seal the ramp opening A, and for this reason, as shown in the imaginary line in the vertical section above the rampway 3, a bulkhead serving as a partition wall is required. A structure in which a door 11 is provided was considered to be ideal.

However, in the conventional structure, as described above, the lamp cover 6 is connected to the deck opening edge 7 by a hinge, so it has been impossible to insert one bulkhead door 11 in a vertical section.

The present invention was developed in view of these problems, and it is an object of the present invention to provide an inboard structure that is equipped with a lamp cover that opens and closes the deck opening, and that allows the installation of a bulkhead door that seals and defines the lamp opening. With the goal.

Therefore, the present invention has a plurality of wheels attached to both sides of the lamp cover, and an inclined rail to guide these wheels on the hull side.
A lifting wire is connected to the lamp cover so that the lamp cover can be moved to a storage position diagonally above the upper deck opening. A bulkhead door sealingly defining the lamp opening is rotatably connected at its upper end by a hinge, so that the bulkhead door can be opened and closed when the lamp cover is in the retracted position.

Embodiments of the present invention will be described below based on the accompanying drawings. Components that are the same as those of the conventional example shown in FIGS. 1 to 3 are given the same reference numerals.

As shown in FIG. 4, two wheels 13 are attached to both sides 12 of the lamp cover 6. Rails 14 for guiding these wheels 13 are installed from the upper deck 1 to the ceiling surface 2 so as to be inclined. A lifting wire 15 is connected to this lamp cover 14 so that it can be moved diagonally upward to a storage position. This pulling wire 15
has one end connected near the wheel 13, and the pulley 1
It is stretched substantially parallel to the rail 14 via the rail 9, and the other end is connected to a winch or jigger cylinder (not shown).

As shown in FIG. 5, a coaming 23 is provided on the deck opening edge 21, and the lamp cover 6 is held in contact with the coaming 23 when it is closed, forming the same plane as the upper deck 1.

Note that a chain or the like may be used instead of the pulling wire 15.

A bulkhead door 16 for sealingly defining the lamp opening A is provided at a position along the deck opening edge 7 in a vertical section above the lampway 3. This bulkhead door 16 has a hinge 22 at its upper end.
The structure is rotatably connected to the deck ceiling surface 18 and has a sealing property in the closed state.

In addition, when the bulkhead door 16 is closed, the lamp opening A, that is, the walls 25 on both sides of the deck opening edge 7, the deck ceiling surface 18, and the rampway 3 are sealed, and not only between the upper and lower decks, but also between the upper and lower decks. Also in the upper deck 1, the front and rear passages of the bulkhead door 16 are watertightly blocked.

While the ship is sailing, the lamp cover 6 is placed in the position shown by the solid line.
and bulkhead door 16 are held, respectively.
In other words, the bulkhead door 16 is located at the deck opening edge 7.
sealingly defining a lamp opening A at a position abutting the lamp;
Prevents water from entering the back of the hold. Further, the lamp cover 6 has one end connected to the bulk head door 16.
As described above, the lamp cover 6 is brought into contact with the lamp cover 6 and is held in a position on the same plane as the upper deck 1, so that the top of the lamp cover 6 becomes a loading area.

On the other hand, when loading or unloading cargo, the bulkhead door 16 and the lamp cover 6 are held in the state shown by the imaginary lines, and the lamp opening A is opened. That is, the lamp cover 6 is moved in parallel diagonally upward by the pulling wire 15 and is held in the vicinity of the ceiling surface 18 via the locking device 24. When the lamp cover 6 is in this retracted position, the bulkhead door 16 is rotated to a position parallel to the ceiling surface 18 and held, but since the lamp cover 6 has already moved in parallel at this time, the rotated bulk head The head doors 16 do not interfere with each other.

Note that since the lamp cover 6 is guided by the wheels 13 via the rails 14, even if some of the wires 15 are cut, the lamp cover 6 does not fall and is held as it is, providing excellent safety.

As explained above, the present invention allows the bulkhead door to be attached by moving the lamp cover in parallel via wheels, rails, wires, etc., and the lamp cover allows the deck opening to be used for loading. In addition, the lamp opening can be sealed and defined by the bulkhead door, which can greatly contribute to improving safety in the event of flooding.
