Description

[Detailed Description of the Invention] This invention relates to a connecting device for a floating hose that is floated on the sea surface and is connected to a ship's piping each time to transfer oil or slurry.

This type of floating hose is connected to, for example, a single-point mooring buoy moored offshore, and when not in use it floats on the sea surface, and when in use it is hoisted onto a ship and connected to a fixed pipe on the ship. However, as ships become larger, more efficient cargo handling operations are required, which means that the floating hoses become larger or the number increases, and the ship moves or sways due to wind and waves, making the above connection work extremely difficult. It is.

This invention was made in view of the above-mentioned circumstances, and it is an object of the present invention to provide a connecting device that can extremely easily connect a set of two floating hoses to shipboard piping at the same time. With the goal.

This invention will be explained below with reference to drawings showing embodiments.

The floating hoses 1 are a set of two, and each hose 1 has an inner flexible tube 2 for passing oil, etc.
A metal tube 3 is fitted to both ends of the flexible tube 2 in a watertight manner by an appropriate means, and a metal tube 3 is fitted over the entire length of the inner flexible tube 2 so that both ends are fitted in a watertight manner to the metal tube 3 by an appropriate means. It consists of an outer flexible tube 4 fixed to. Although not shown, the metal tube at the base end of each hose 1 is connected to the tip of a tube rotatably attached to a single point mooring buoy. Furthermore, air is sealed between the inner and outer flexible tubes 2 and 4, thereby allowing the hose 1 to float on the sea surface. The tips of the two hoses 1 are connected to each other by a holding frame 5. Two guide elongated holes 6 are provided on both sides of the frame 5, and guide pins 7 are integrally formed on both sides of each metal tube 3 and are movably fitted into these elongated holes 6. The distal end portions of each metal tube 3 are bent at a substantially right angle so as to face oppositely to each other, and a flange 8 is formed at the distal end. Also, one of the two metal tubes 3 of the hose 1 is provided with a rack 9, and the other is driven by an air motor.
A pinion 10 is provided which meshes with the rack 9, and by driving an air motor connected to a suitable air source, the two metal tubes 3 or flanges 8 are moved toward and away from each other.
Furthermore, a floating hose positioning member 11 that protrudes long toward the distal end of the metal tube 3 is integrally formed in the center portions of both sides of the frame 5, and a tapered inclined surface 11a is formed at the distal end of this member 11. Usually, the flange 8 at the tip of each metal tube 3 has a sealing lid (not shown).
are attached, and the hoses 1 are floating on the sea surface in a state where they are closest to each other. Furthermore, a marker buoy (not shown) that indicates the location of the hose 1 is attached to the tip of the hose 1 by a cable.

The ship 12 is provided with a floating hose guide hole (passage) 15 extending from the upper deck 13 to the ship's side 14, and this hole 15 is large enough to allow the tip of the hose 1 that is closest to it to pass through easily. has. A mobile crane (lifting device) 16 is provided on the upper deck 13. This crane 16 is provided with a floating hose positioning member 17, and this member 17 is formed with a diagonally downwardly facing inclined surface 17a corresponding to the inclined surface 11a of the positioning member 11 of the hose 1 in an opposing manner. Furthermore, two fixed pipes 18 are arranged on the upper deck 13 to be used in connection with the hose 1.
The tips of 8 are the two hoses 1 that are closest together.
The flanges 8 of the flanges 8 face each other with an interval larger than the distance between them.

In the above, floating hose 1 is connected to ship 1.
The connection to the second fixed tube 18 is performed as follows. That is, the messenger rope 20 is lowered to the sea surface from the winch 19 of the crane 16 through the guide hole 15, and the positioning member 11 of the hose 1 is lowered to the sea surface.
This rope 20 is connected to the tip of the hose 1, and the tip of the hose 1 is lifted up to above the upper deck 13 through the guide hole 15 using a winch 19. Since the marker buoy is attached to the tip of the hose 1, the hose 1 can be easily roped from the ship 12. Moreover, even if the hose 1 is large, and even if the ship 12 is shaken, the hose 1 can be easily lifted along the guide hole 15 without shaking. As shown in FIG. 2, when the hose 1 is lifted to a predetermined height, the inclined surfaces 11a and 17a of the positioning members 11 and 17 of the hose 1 and the crane 16 come into contact with each other, and the hose 1 is positioned. Therefore, the winch 19 is stopped. At this time, the flange 8 of each hose 1 faces the tip of each fixed tube 18, respectively. Finally, the flanges 8 of the two hoses 1 are separated from each other using an air motor and connected to the tips of the fixed tubes 18, respectively. At this time, since the frame 5 connecting the hose 1 is reliably positioned by the positioning members 11 and 17,
Connecting the hose 1 is extremely easy.

If the floating hose 1 is to be removed from the fixed tube 18 and floated on the sea surface again, the above operation may be performed in reverse.

The floating hose 1, the mechanism for connecting the two hoses 1 to approach and separate them, the floating hose lifting device, etc. are not limited to those of the above embodiments, and can be modified as appropriate. In addition, the floating hose guide passage runs from the upper deck 13 to the ship side 14.
It may be in the form of a groove that extends to .

As described above, the connecting device according to this invention includes two floating hoses 1 whose tips are bent at almost right angles, and these two floating hoses 1.
a holding frame 5 that holds the tips of the floating hose 1 so that the tips thereof face oppositely to each other and can approach and separate from each other; a lifting device 16 provided on the upper deck 13 for lifting the holding frame 5 at the tip of the floating hose 1; a floating hose positioning member 11 provided with tapered inclined surfaces 11a on both sides of the tip end;
A floating hose positioning member 17 provided on the lifting device 16 and having diagonally downward inclined surfaces 17a facing each other corresponding to the inclined surface 11a of the positioning member 11 of the holding frame 5;
Since the floating hose 1 is provided with two fixed pipes 18 arranged on the upper deck 13 so as to face each tip of the floating hose 1 lifted and positioned by the Furthermore, even if the ship 12 is shaken, a set of two hoses 1 can be easily lifted and positioned at the same time without shaking along the guide path 15, and the two hoses hoisted in this way can 1 set of hoses 1
can at the same time be connected very easily to the fixed pipe 18 on board the ship.
