DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a hull block in which a plurality of longitudinal members, transformer members and the like are assembled on a skin plate such as an outer plate, a deck and a bulkhead of a hull to form a block.

[0002]

2. Description of the Related Art Generally, when building a hull, a hull block is constructed by dividing an outer plate, a deck, a bulkhead and the like of the hull in advance, and the hull blocks are assembled to construct a hull.

Conventionally, when building a flat hull block, as shown in FIG. 7 , a plurality of longitudinal members 2 are welded to a skin plate 1 to form a panel block 3, and this panel block 3 is formed. As shown in FIG. 8 , a method of assembling the hull block by assembling the transformer member 4 and assembling the longitudinal member 2 with a plurality of transformer members 4 in advance to form a framework block 5, and attaching the framework block 5 to the skin plate 1. To build a hull block.

[0004]

By the way, in the conventional method shown in FIG.
In addition, since a large notch 7 is formed in the slot 6 of the transformer member 4, when the transformer member 4 is assembled to the panel block 3, as shown in FIG. The member 4 can be suspended from above and assembled to the panel block 3.

However, since the slot 6 has a large notch 7 as shown in FIG. 9 , a color plate 8 must be attached to the notch 7 to close it. The work had to be done manually.

On the other hand, in the conventional method shown in FIG. 8 , a slit-shaped slot 9 as shown in FIG. 10 is formed in the transformer member 4 and the long member 2 is inserted through the slot 9 to form a frame block. 5, the color plate 8 does not need to be attached unlike the slot 6 in FIG .

However, when constructing the framework block 5, the plurality of transformer members 4 are erected at predetermined intervals by a jig, and the long members 2 are manually inserted into the slots 9 of the transformer members 4 one by one. Framework block 5
In this case, the insertion of the long member 2 takes a lot of time, and the welded joint formed between the skin plate and the long member and the transformer member remains in a grid shape, which makes automation difficult. there were.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems of the conventional method. It is an object of the present invention to form a slit type slot in a transformer member and to simultaneously form a large number of long members in the slots. It is an object of the present invention to provide a method for constructing a hull block in which a hull block can be formed in a short time by inserting a hull block.

[0009]

Incidentally, the panel block 3 should be formed.
FIG. 6 shows that when the longitudinal member 2 is welded to the skin plate 1,
As shown in the figure, the longitudinal member 2 is perpendicular to the skin plate.
It can be attached, but it may be
An error may occur in the upright angle of the member 2,
If the upright angle accuracy is low, the slot 9 of the transformer member 4
Cannot be inserted through the long member 2.

Therefore, the transformer holding equipment 10 and the moving surface plate
32 to correct the upright angle of the longitudinal member 2
A correction device 39 is provided.

The longitudinal correction device 39 has a body 40
Between the transformer holding equipment 10 and the moving surface plate 32 in the width direction
(In the direction of the arrow Y)
The main body 40 is provided in the width direction.
A plurality of movable correction units 41 are provided.

The long member 2 is inserted into these correction portions 41.
A long insertion hole 42 is formed, and the
A straightening roller for correcting the upright angle of the longitudinal member 2 (see FIG.
(Not shown).

Next, the method of the present invention will be described with reference to the above equipment examples.

In carrying out this method, a plurality of transformer members 4 (shown in FIG. 5) provided with slit-shaped slots 9 through which the long members 2 are inserted are manufactured in advance.
A panel block 3 is manufactured by welding a plurality of long members 2 to a skin plate 1.

On the other hand, the transformer holding equipment 10 moves each of the gripping and positioning devices 11 in the front-rear direction (X direction in FIG. 1) to be positioned at a predetermined interval, and arranges the gripping and positioning devices 11 on both sides to face each other. .

Next, the transformer member 4 is placed on each gripping positioning device 11 (FIG. 2), and the width direction positioning device 1
7 and the positioning and adjusting device 18 are positioned in the width direction (the Y direction in FIG. 1), and are held and fixed by the clamps 19 of the respective clamp supporting devices 20 (FIG. 3).

Next, after disposing the panel block 3 on the moving platen 32 and positioning the panel block 3 with the two guide devices 34, the draw chain 33 is driven to move the panel block 3 toward the transformer holding equipment 10. I do. This and
Insertion of the straightening portion 41 provided with two rows of the long members 2
A straightening roller built in by being inserted through the hole 42
Thus, the upright angle of the longitudinal member 2 is corrected to an appropriate angle. So
Then, the front end of each of the long members 2 of the panel block 3 is inserted into the slot 9 of the transformer member 4 having the most upright end, and the panel block 3 is moved while being guided by the panel guide 27 so that the panel block 3 is sequentially upright. The long member 2 is inserted through the slot 9 of the transformer member 4 to be assembled, and the transformer member 4 is assembled to the panel block 3.

As described above, the longage straightening device provided in two rows
By setting the position 39, the upright angle of the longitudinal member 2 is set to an appropriate angle.
It is corrected and the moving direction is adjusted to an appropriate angle (trans member 4
At a right angle to the transformer member 4).
The long member 2 can be smoothly inserted into the slot 9.
Work efficiency can be improved.

At this time, the width direction positioning device 17 and the positioning adjusting device 18 are lowered or moved so as not to hinder the movement of the panel block 3 as shown in FIG. 4 (FIG. 4).

After the panel block 3 assembled with the transformer member 4 is welded by a welding robot or the like, the panel block 3 is conveyed out of the surface plate 12 by a crane or the like.

The movement of the panel block 3 and the positioning of the transformer member 4 are automatically performed by an automatic controller (not shown).

As described above, since each of the long members 2 of the panel block 3 is inserted into each of the slots 9 of the transformer member 4 at the same time, the assembling work can be performed in a short time. This can be done automatically by an automatic controller.

Further, since the transformer member 4 is provided with the slit type slot 9, there is no need to attach a color plate.

When a double hull block is to be constructed, the hull block constructed as described above is inverted, and each of the transformer members 4 of the hull block is positioned at a predetermined position by the gripping and positioning equipment 10, and then the other hull blocks are positioned. A double hull block can be constructed by moving the panel block from the movable platen 32 toward the transformer holding equipment 10 and sequentially inserting the long members of the panel block into the slots 9 of each transformer member 4.

[0040]

In summary, according to the present invention, a plurality of transformer members are held upright at predetermined intervals in parallel, the panel block is moved, and the skin straightening device is used by the longitudinal correction device.
While correcting the upright angle of the longitudinally welded longitudinals integrally with the plate, the longitudinal members are inserted into the slots of the transformer members, so that the longitudinal members can be smoothly inserted into the slots of the transformer members. , A lot of long members can be inserted through the slot at the same time, and the insertion work is automatically and easily and quickly
It can be carried out.
