Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a flying boat and a method for manufacturing a flying boat.

[0002]

2. Description of the Related Art Conventionally, a body of a flying boat has been manufactured by assembling a frame structure with an aggregate and then attaching an outer plate to the frame structure. However, in the method of integrally manufacturing the entire machine body as described above, a huge jig is required, and workability and productivity are poor.

Therefore, as shown in FIG. 7, a manufacturing method has been proposed in which a flying boat is divided into a plurality of blocks 101 to 110 in the front-rear direction, and these blocks are manufactured separately and then assembled.

However, since the flying boat is used on the water, unlike the land-based aircraft, the watertightness and waterproofness of the airframe are highly required. Therefore, in the conventional manufacturing of a flying boat, a method of completing the entire block inside one assembly jig was adopted in order to secure watertightness and waterproofness.

[0005]

However, with this method, the manufacturing operator is often forced to work in a narrow space inside the assembly jig, and also to work in a posture that makes it difficult to work. In addition, due to the jigs, it is often difficult for the worker to approach the work target site sufficiently,
It was sometimes difficult to work at hand.

Since the workability is poor as described above,
In particular, with respect to the bottom of the boat, which requires watertightness, in order to improve the accuracy of the work, the assembly work was performed with the bottom facing upward. In other words, the boat bottom was manufactured with the top and bottom reversed. However, in this case, after making the boat bottom,
It was necessary to turn the bottom of the boat upside down, which was a factor in reducing the productivity of the flying boat.

The present invention has been made in view of the above points, and an object of the present invention is to facilitate the work of a worker in manufacturing a flying boat and improve productivity.

[0008]

The flying boat according to the present invention comprises:
A flying boat having a boat bottom and a body portion provided above the boat bottom, wherein at least a part or all of the boat bottom is constructed by assembling a plurality of panel-shaped members divided in the left-right direction of the airframe. It is formed by.

In the above and below, the panel-shaped member means a member made of a thin-walled member, and the entire shape thereof is not limited to a flat plate-shaped member. Therefore, the panel-shaped member is not limited to a flat-plate-shaped member whose overall shape is flat or curved, and is not limited to a flat-plate-shaped member.
Or the thing provided with two or more protrusion members is also included.

The flying boat is manufactured by manufacturing a plurality of panel-shaped members which are divided in the left-right direction of the machine body and then assembling the panel-shaped members together. Therefore, the individual panel-shaped members do not have to be manufactured inside the jig, and can be manufactured with a sufficient space in both left and right directions. Therefore, the worker can perform the manufacturing work in a posture that is easy to work, and the accessibility of the worker to the manufacturing place is improved. Further, since the workability is improved, the accuracy of the work is increased, and it is not necessary to manufacture the boat bottom part upside down. Therefore, productivity is improved.

A keel extending in the front-rear direction of the body is provided at the center of the boat bottom in the left-right direction, and at least a part of the boat bottom is one or more panel-shaped members divided into left and right sides of the keel. It may be formed by assembling.

As described above, the panel-shaped members are divided into left and right parts with the center portion in the left-right direction of the machine body as a boundary, so that the panel-shaped members are substantially symmetrical. Therefore, workability in manufacturing each panel-shaped member is improved, and the panel-shaped member is easily handled during assembly.

It is preferable that a waterproof material is filled at least between the joint surfaces of the panel-shaped members at the bottom of the boat.

By filling the waterproof material between the joint surfaces of the panel-like member in this manner, the gap between the joint surfaces is sealed. Therefore, the watertightness between the panel members is improved.

By the way, if a plurality of compartments are formed inside the boat bottom by a plurality of compartment walls provided in the front-rear direction, even if a part of the boat bottom is flooded, a part of It is only necessary to submerge the compartment of the boat and prevent the entire bottom of the boat from being flooded.

Therefore, a plurality of compartments are formed inside the boat bottom by a plurality of compartment walls provided in the front-rear direction of the machine body, and the panel-shaped member at the bottom of the boat is a part of the compartment wall. It is preferable that the panel-shaped members have partition walls, and the panel-shaped members are assembled by joining the divided partition walls to each other so as to form the partition walls.

With this, the partition wall is divided together with the panel-like member, so that a flying boat having a plurality of partition walls at the bottom of the boat can be manufactured with good workability.

The boat bottom is provided with a leg mechanism that can be accommodated in the boat bottom, and the boat bottom is a non-divided panel-shaped member that accommodates the leg mechanism, and a pair of left and right pairs or two or more pairs. It is preferable to have the split type panel-shaped member.

The panel-shaped member for accommodating the leg mechanism is required to have its legs taken in and out, and therefore it is particularly preferable to improve waterproofness. According to the above configuration, since the panel-shaped member that houses the leg mechanism is formed of the non-divided panel-shaped member, it is possible to improve waterproofness.

It is preferable that part or all of the body portion is formed by assembling two or more panel-shaped members divided in the circumferential direction of the machine body.

With this, not only the boat bottom but also the body is constructed by assembling the panel-like members, so that workability and productivity can be further improved.

A method for manufacturing a flying boat according to the present invention is directed to a port-side panel-like member that constitutes part or all of the port-side portion of the boat bottom and a starboard-side panel-like member that constitutes part or all of the starboard-side portion. And port side panel-shaped members and the starboard side panel-shaped members are assembled to produce part or all of the boat bottom.

As a result, workability and productivity can be improved for the reasons described above.

In the manufacturing method, the port side jig is installed, and the starboard side jig is installed at a position apart from the port side jig, and the port side panel-like member is manufactured using the port side jig. On the other hand, it is preferable that the starboard-side panel-shaped member is manufactured by using the starboard-side jig.

As a result, since the port side jig and the starboard side jig are provided at positions separated from each other, the operator can place the port side panel-shaped member and the starboard side panel-shaped member in wide working spaces. Can be manufactured.

When assembling the port-side panel-shaped member and the starboard-side panel-shaped member, it is preferable to interpose a waterproof material between the joint surfaces of the port-side panel-shaped member and the starboard-side panel-shaped member.

As a result, the watertightness between the panel-shaped members can be improved.

Before assembling the port-side panel-shaped member and the starboard-side panel-shaped member, a keel may be provided in advance on the port-side panel-shaped member or the starboard-side panel-shaped member.

This eliminates the need to newly install a keel after completing both panel-shaped members.

[0030]

As described above, according to the present invention, the panel-shaped member forming the bottom of the boat is divided into left and right parts.
The worker can perform the manufacturing work in a state where a sufficient space is secured on both sides of the panel-shaped member. Therefore, the worker can manufacture the panel-shaped member in a posture that is easy to work, and it becomes easy to carry out the manufacturing work at hand. Therefore, workability can be improved. Also,
Since the accuracy of the work increases as the workability improves, it is not necessary to fabricate the bottom of the boat face down. Therefore, productivity can be improved.

A plurality of floor panels 15 arranged in the front-rear direction are provided between the boat bottom portion 2 and the body portion 3.

Next, a method of manufacturing the flying boat 1 will be described. In this manufacturing method, first, each element member (panel-shaped member or the like) is manufactured using a predetermined jig, and then the element members are assembled. That is, a so-called panel assembly method is adopted.

The pair of left and right panel-shaped members are manufactured using independent jigs. For example, as shown in FIG. 3, the second boat bottom panel 12a on the starboard side is manufactured using the first jig 41, and the second boat bottom panel 12b on the port side is manufactured using the second jig 42. It The first jig 41 and the second jig 42 are provided at positions separated from each other. As a result, a sufficiently wide space 43 for manufacturing work is secured between the first jig 41 and the second jig 42.
Further, unlike the conventional method in which the entire block is completed inside one assembly jig, the inside of the panels 12a and 12b is open, so that the operator can use the panels 12a and 12b.
The production work can be done from both sides. Therefore, the accessibility of the worker is improved, and the work of the worker is facilitated.

CAD is used for the design and production of each panel-shaped member. Therefore, each panel-shaped member is manufactured with high precision, and the joint portion between them is also precisely formed. Therefore, when the panel-shaped members are coupled to each other, the coupling portions are unlikely to be misaligned.

By the way, it is not preferable to separately provide a dedicated joint for assembling the panel-like members when assembling the panel-like members, since this causes an increase in the number of parts and weight. Therefore, in the present embodiment, in the manufacturing process of each panel-shaped member, the bolt holes, the rivet holes, etc. are exposed in the joint portion of each panel-shaped member, in other words, the panel part is left unfinished, The unfinished portion is completed when the members are joined (in the assembly process). Thereby, a dedicated joint (splice part) for assembling the panel-shaped members is omitted.

Next, the method of assembling the panel-shaped member will be described by taking as an example the connection between the second boat bottom panels 12a and 12b.

As shown in FIG. 4, the split-type panel-shaped members of the boat bottom portion 2 are joined together via a keel 22. Second
The boat bottom panels 12a, 12b have a plurality of frames 45 arranged in the front-rear direction at predetermined intervals and an outer plate 44 attached to the frames 45. In addition, in FIG. 4, for ease of understanding, only the frame 45 is illustrated for the second boat bottom panel 12a on the starboard side,
Illustration of the outer plate is omitted.

The keel 22 is the second boat bottom panel 1 on the port side.
Pre-bound to 2b. On both the left and right sides of the front end of the frame 45 on the starboard side second boat bottom panel 12a,
Clips 46 having an L-shaped cross section are connected to each other.
One piece of the clip 46 is provided with a plurality of rivet holes 47 aligned in the longitudinal direction of the clip 46 (vertical direction in FIG. 4), and these rivet holes 47 connect the clip 46 and the frame 45 with rivets (see FIG. (Not shown). In addition to the clip 46, the clip 46
Is provided with a plurality of rivet holes 48 arranged in the longitudinal direction. On the other hand, the keel 22 is provided with a rivet hole 49 corresponding to the rivet hole 48 of the clip 46. As described above, the respective panels 12a and 12b are manufactured in a state in which the joint portion is incomplete, and the panels 12a and 12b are not manufactured.
Since the unfinished parts are completed when the b is joined, no special splice part is required.

In connecting the two panels 12a and 12b, first, to one or both of the joint surfaces of the two panels 12a and 12b (the joint surface of the clip 46, the side surface of the keel 22, etc.),
A sealant (not shown) is applied as a waterproof material. Then, the panels 12a and 12a are aligned so that the rivet hole 48 of the clip 46 and the rivet hole 49 of the keel 22 are aligned.
Join b. At this time, the divided partition walls 31 of both panels 12a and 12b are also watertightly joined together by using a sealant. Next, a rivet is driven into the rivet hole 48 and the rivet hole 49, and both panels 12a and 12b are riveted. After that, the sealant hardens and both panels 12a,
The gap between 12b will be sealed watertight.

As shown in FIG. 5, a plate member 50 is provided at the bottom of the boat bottom 2, that is, at the joining portion between the boat bottom panels 12a and 12b to cover the joining portion from the outside. The plate member 50 is a plate-like member elongated in the front-rear direction like the keel 22, and the left and right sides of the plate member 50 are gently inclined upward so as to follow the shape of the bottom of the boat bottom 2. . The plate member 50 and both panels 12a and 12b are riveted together with a sealant filled between their joint surfaces. By providing such a plate member 50, the panel 12
The watertightness between a and 12b is improved.

The other panel-shaped members are also joined to each other using the above-described assembling method. At this time, FIG.
As shown in (a), the pressurizing body 20 and the panel 1 at the bottom of the boat 1
Similar to the connection between the panels 12a and 12b, 2a and 12b are directly connected without using a splice part. Further, as shown in FIG. 6 (b), the upper panel 19 and the side panels 17a and 17b are directly connected to each other, and the boat bottom panels 14a and 14b and the floor panel 15 are directly connected to each other without using splice parts. Make a join.
In the present embodiment, the side panels 17a, 17b and the boat bottom panels 14a, 14b are joined using the splice parts 51, but these panels can also be joined directly.

As described above, according to the present embodiment, since the machine body 6 is constructed as a combined body of a plurality of panel-shaped members, each panel-shaped member is manufactured independently and then the panel-shaped members are manufactured. By assembling, the machine body 6 can be manufactured. Therefore, the machine body 6
Since it is not necessary to manufacture the inside of one assembly jig, the jig can be downsized.

In particular, since the panel-shaped members are configured to be divided in the circumferential direction of the machine body, unlike the case of dividing the panel-shaped members in the front-rear direction of the machine body, when the panel-shaped members are manufactured using a jig, A sufficient working space can be secured on both sides of the panel member. Therefore, the worker can perform the work in a posture that facilitates the work, and also can easily perform the work at hand. Therefore, the workability of the worker can be improved.

Further, since the boat bottom 2 can be manufactured with high accuracy without turning it upside down, the productivity can be improved. The scaffolding of the jig can be maintained well, and work at high places can be eliminated.

Panel-like members 12a, 12b of the boat bottom 2
14a, 14b and side panels 16a, 16b of the body portion 3
Like 17a and 17b, the panel-shaped members that are divided into the left and right are configured to be substantially bilaterally symmetrical, so that the panel-shaped members can be easily handled.

When the panel-shaped members are assembled together, the joint surface thereof is filled with the sealant, so that the watertightness and waterproofness can be improved.

It should be noted that the embodiment of the present invention is not limited to the above-mentioned embodiment, and of course other embodiments are possible. The number of divisions of the machine body 6, that is, the number of panel-shaped members, is not limited to a specific number, and can be set as appropriate according to the size of the machine body 6, application, and the like. The connection between the panel-shaped members is not limited to the rivet connection, and other connection methods may be used. The waterproof material provided on the joint surface between the panel-shaped members is not limited to the sealant, and may be another filling material or another waterproof material.
