Description

[Detailed description of the invention] (Field of industrial application) The invention is a combination boat for suspending a combination boat having a fiber-reinforced plastic hull in an air expansion chamber from a mother ship via a suspension cable. This relates to a suspension device for boats.

(Prior Art) Conventionally, a combination boat having an air expansion chamber and a hull made of fiber-reinforced plastic has a suspension device for suspending the boat from a mother ship via a suspension cable. As shown in FIG. 5, a conventional suspension device for a combination boat has suspension rings 5a, 7a installed at four locations on the front, rear, left and right sides of a body portion 2a consisting of an air expansion chamber. The hanging rings 5a and 7a are formed to connect one end of the hanging cable 14a to the outer surface of the air expansion chamber 2a,
In other words, since it is located outside the side of the hull, if the boat is lowered from the mother ship to the sea and then runs with the suspension rope 14a still attached to the boat, a part of the suspension rope 14a may be damaged. Since the suspension cable 14a is located outside the ship's hull, the suspension cable 14a may somehow jump out of the ship and wrap around the screw, creating a danger.
must be completely removed from the hanging rings 5a, 7a and kept neatly on the deck 4a. Despite this, people often neglect to do this due to laziness or in a rush to respond in an emergency, and when lifting and lowering a boat, the hanging rope 14a is connected to the hanging rings 5a, 7a.
There were drawbacks such as the fact that workers had to stick their heads out of the boat when connecting them to the boat, making it difficult for them to recognize dangers.

(Problems that the invention attempts to solve) In order to eliminate the above-mentioned drawbacks, the present invention installs hanging rings at four locations: the deck surface at the forward left and right positions of the hull, and the left and right positions on the inner wall surface of the transom. By providing the ring inside the hull, the entire suspension cable can be completely accommodated inside the hull even if one end of the suspension cable remains connected to the suspension ring and is neatly arranged on the deck. This makes it easier to dispose of hanging ropes, and allows workers to connect the hanging ropes to the hanging rings without sticking their heads out of the boat during boat hoisting work. The installed suspension ring is installed via bolts to a fixing base that is fixed to the inner surface of the bottom of the ship, which forms the hull, using fiber-reinforced plastic material, and prevents damage or bending of the suspension ring attachment part when the hull is lifted. It is constructed with a structure that prevents this.

(Means for Solving the Problems) An example of the implementation of the present invention will be explained below with reference to the drawings.
It is formed with a hull 3 made of fiber-reinforced plastic, and hanging rings 5 are installed on the left and right positions in front of the deck 4 of the hull 3, and hanging rings 7 are installed on the left and right positions of the inner wall surface of the transom 6. , 7 are installed.

On the inner wall surface of the bottom part 8 forming the hull 3,
As shown in FIG. 3, a cross-sectional fixing base 9 is integrally fixed and installed directly below each of the hanging rings 5, 5 provided on the deck 4, and this fixing base 9 has a washer 1 on the back side.
0 and protrude the plurality of bolts 11 upward,
A space 1 formed between the fixed base 9 and the bottom part 8
2 is filled with a fiber-reinforced plastic material, and the fixing base 9 is strongly integrated with the bottom part 8 of the ship and fixedly installed. Then, the hanging ring 5 is inserted through the bolt 11.
The board part 13 of the deck 4 is fixedly installed on the deck 4 so that it can be suspended from the fixing base 9 via the bolts 11 when the hull is lifted.
It is formed in such a way as to prevent the mounting part from being damaged or bent.

In addition, in Figures 2 and 3, 15 is the hull 3.
Left and right hanging rings 5, 5 provided on the deck 4 of
This reinforcing wall 15 has pillars 16, 17, 17' standing upright and protruding at a predetermined interval in the center and left and right parts, and these pillars 16, 17 , 17' are formed by forming an outer shell from fiber-reinforced plastic material, filling the inside with hard urethane foam, and installing the hard urethane foam on a line crossing the left and right fishing rings 5, 5.

Moreover, in FIG. 4, the rear suspension rings 7, 7 are installed at the left and right positions at the rear of the deck 4, similar to the suspension rings 5, instead of being installed on the transom 6.
The means for installing the hanging rings 7, 7' is the same as that for the hanging ring 5.

(Function) Since the present invention has the above-mentioned configuration, the hanging rings 5 are installed at four locations: the surface of the deck 4 at the forward left and right positions of the hull, and the left and right positions of the inner wall surface of the transom 6;
5, 7, and 7 are all provided inside the hull, that is, inside the body part 2, so that when lifting and suspending the boat 1, the operator can easily connect the suspension rope 14 without sticking his head out of the boat. Hanging ring 5,5
and 7,7. Even if one end of the suspension cable 14 is kept connected to the suspension rings 5, 5 and 7, 7 and arranged on the deck 4, the entire suspension cable 14 cannot be used completely inside the hull. Therefore, not only can the suspension rope 14 be disposed of extremely easily, quickly and safely, but also the suspension rope 14 will not fall overboard while the boat 1 is running. Furthermore, since the hanging rings 5, 5 lift the hull on a fixing base 9 fixedly installed on the bottom 8 of the ship via bolts 11, the attachment part of the hanging ring 5 of the deck 4 is prevented from being damaged or bent, and is fixed. The stand 9 is completely integrated with the hull 3 using fiber-reinforced plastic material and is adhesively installed, and by providing a reinforcing wall 15 on a line that crosses these left and right suspension rings 5, it is sufficient to bear the load of the hull. It must be installed firmly and securely so that it can withstand

(Effects of the invention) Therefore, the present invention provides a suspension device in which a hanging ring is installed inside a boat, that is, inside a body portion consisting of an air expansion chamber, and the work of connecting a hanging rope to the hanging ring is performed. Workers can do this without sticking their heads out of the ship, making it easy and safe to handle the suspension ropes.Moreover, the suspension ropes can be connected to the suspension rings without being removed from them. It is also possible to organize them on the deck in their original state.
Emergency dispatch of lifeboats can be carried out even more safely and quickly, and furthermore, the hanging rings installed on the deck are
It is installed via bolts to a fixed base that is fixed to the bottom of the ship, so when the ship is lifted,
The hanging ring is suspended from a fixed base via bolts, which prevents the attachment part of the hanging ring on the deck from being damaged or bent. It has the advantage that it is completely integrated and adhesively installed in the ship body 3, so that it can be installed firmly and reliably to withstand the load of the ship's hull.
