Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an aggregate assembling device suitable for attaching aggregate to a curved outer plate block forming a curved surface portion of a hull outer shell.

Generally, the block construction method is used for the construction of large ships. In carrying out this block construction method, the curved shell block, which forms the hull's outer shell, is constructed with a longitudinal material 12 attached longitudinally to the inner surface of the curved outer shell 10, as shown in Figures 1 to 3. ,
It is constructed by distributing an aggregate consisting of a transformer material 14 orthogonal thereto. A slot 16 into which the lodge material 12 is inserted is formed in the transformer material 14, and welding between the longitudinal material 12 and the transformer material 14 is performed at this insertion portion. Further, each of the aggregates is assembled into a single body by welding to the curved outer plate 10.

Conventionally, one method for assembling this type of curved outer panel block is to assemble the lodge material 12 and the transformer material 14 to each other in advance, and then assemble this framed aggregate to the curved outer panel 10. A framework method is known. This can be done by arranging the transformer material 14 in advance with the slot 16 facing upward, and then assembling the lodge material 12 thereon and temporarily attaching it to each other, or alternatively, after arranging the lodge material 12 in advance, the transformer material 14 is placed with the slot 16 facing downward. A framework structure is created by assembling and tacking.

However, conventional aggregate assembling devices for constructing aggregate frameworks only have means for independently supporting the longitudinal members 12 and the transformer members 14, and the longitudinal members 12 and the transformer members 14 cannot be bent. It is difficult to match the curved surface of the outer panel 10, and there is a problem in that a step is created particularly at the intersection. Therefore, it was necessary to assemble the frame while adjusting each intersection, and the workability of accurate positioning was extremely poor.

The present invention focuses on the above-mentioned conventional problems, and provides an aggregate framework for a curved exterior panel block that facilitates accurate positioning work and improves workability when constructing an aggregate framework for a curved exterior panel block. The purpose is to provide equipment.

In order to achieve the above object, an aggregate framework device for a curved outer panel block according to the present invention includes a longitudinal pedestal installed at the intersection of a longitudinal material and a transformer material, which are aggregates of a curved outer panel, and a transformer. and a transformer cradle that supports the end of the longitudinal material, the longitudinal cradle has a gripping arm for the longitudinal material, and between the longitudinal cradle that are arranged vertically in the longitudinal direction of the transformer material, there is a lower part of the transformer material on the side where the longitudinal material is attached. An inflatable air tube with a guide plate disposed along the edge is passed over the tube, and positioning can be performed by pushing up a long member through the guide plate.

With this configuration, when air is injected into the air tube after framing the aggregate on each pedestal, the guide plate moves upward, pushing up the Ron and Zo materials, and the guide plate follows the lower edge of the transformer material. The lower edge intersection of the Ronno material and the transformer material is accurately positioned. Therefore, when this is temporarily attached and matched to the curve P outer panel, it matches the curvature of the curve P outer panel, and the curve 9 outer panel block can be assembled with high precision.

The longitudinal pedestals 20 and transformer pedestals 22 constituting each row are attached to one base 24, as shown in FIG. The base 24 is installed below the set position of the transformer material 14 so as to extend in its longitudinal direction, and has a rail 26 on its upper surface. First, the longitudinal pedestal 20 has a pedestal 28 that can be moved along the rail 26, and a piece pedestal 30 is placed on this pedestal 28.

A guide 32 with a built-in guide 32 is fixed, and a rod 34 that fits into the guide 32 and a support 36 attached to the tip thereof are movable up and down. A gripping arm 38 arranged in a bifurcated manner so as to sandwich the transformer material 14 is pivotally attached to the support body 36, and the gripping arm 38 is rotatable in the longitudinal direction of the transformer material 14.
The gripping arm 38 has a groove 4 into which the lower edge of the longitudinal material 12 can be inserted.
0, and is formed with a width larger than the plate thickness of the longitudinal material 12. Furthermore, a semi-cylindrical tube receiving part 42 is attached to the upper surface of the support body 36 which is held between the gripping arms 38. The tube receiving part 42 is attached so that the groove direction thereof extends to the lower edge of the transformer material 14. Further, the tube receiving portion 42 is connected to the gripping arm 3.
It is set at a lower position than the groove 40 of No.8. As described above, such longitudinal cradle 20 is arranged in a column along each transformer material 14, and between the longitudinal pedestals 20 arranged in a column, there are air tubes 4 as shown in FIGS. 4 and 5.
The 4th bet has been passed. That is, the air tube 44 is
It is supported and attached to the tube receiving portion 42 of each longitudinal holder 20. This air tube 44 has one end closed,
The other end is connected to an air supply/discharge means (not shown), and air can be supplied/discharged and expanded/contracted. Also, air tube 4
A guide plate 46 is attached to the upper surface of the transformer member 14 over its entire length, and the guide plate 46 can be brought into contact with the lower edge of the transformer material 14 when the tube 44 is expanded.

On the other hand, transformer pedestals 22 are attached to both end sides of the base 24, and are formed substantially the same as the longitudinal pedestals 20. That is, it has a pedestal 48 that can move on the rail 26 and a guide 50 fitted onto the pedestal 48, and a guide 52 having a built-in elevating mechanism (not shown) is provided on the pedestal 50. A support body 56 is fixed to the upper end of the rod 54 that fits into the guide 52, and is movable up and down. Support body 56
are provided with gripping means 58 directed towards the side edges of the transformer material 14. The gripping means 58 has a gripping plate 60 that presses the front and back surfaces of the transformer material 14, and is attached to the support body 56 so as to be rotatable around the line of sight of the transformer material 14.

The method for constructing aggregate framework using the apparatus constructed as above is as follows.

First, the longitudinal pedestal 20 and the transformer pedestal 22 are installed at predetermined positions in accordance with the height and inclination of the longitudinal material 12 and the transformer material 14. This is done by moving each pedestal 20.22- along the rail 26 and moving it approximately 30.50 mm relative to the pedestal 28.48, and the height is adjusted by operating a lifting mechanism (not shown). All you have to do is decide. However, since the gripping arm 3B and the gripping means 5g are respectively rotatable, they may be fixed at an appropriate tilted position. These installation values can be easily determined since each value of the curved outer plate block to be assembled is determined. Note that the longitudinal pedestal 20 is set slightly lower to account for the rise caused by the air tube 44.

Next, after inserting and distributing the longitudinal material 12 into the groove 40 of each longitudinal pedestal 20, the transformer material 14 is disposed and supported by the transformer pedestal 22. When assembling the transformer material 14, the longitudinal material 12 is fitted into the slot 16, and since the longitudinal material 12 has a wide groove 40, it can be easily assembled.

In addition, the longitudinal material 12 is held in the longitudinal holder 20 by the groove 40.
However, the transformer material 14 is held in a fixed position at the correct position during assembly by the gripping means 58 (FIG. 7(A)).

After assembling this aggregate, air is supplied to the air tube 44,
This is to inflate the air tube 44. By this air supply, the guide plate 46 attached to the upper surface of the air tube 44 moves upward, pushing up the longitudinal material 12 which is held freely to some extent. Then, the guide plate 46 is brought into contact with the lower edge of the transformer material 14 and is shaped to follow the lower edge, and at this point the height positions of the transformer material 14 and the longitudinal material 12 are determined (Fig. 7 (B) )).

Next, the longitudinal material 12 is biased in one direction and adjusted so that the back of the longitudinal material 12 properly abuts one side edge on the welding side in the slot 16 of the transformer material 14.
2 and the transformer material 14 are temporarily attached at each position and welded to complete the framework.

By attaching this to the curved outer panel, the final curved outer panel block is assembled.

In this manner, according to this embodiment, the longitudinal material 12 and the transformer material 14 are positioned by expanding the air tube 44 provided with the guide plate 46, so that the positioning of both can be performed extremely easily.

Furthermore, since the guide plate 46 follows the lower edge of the transformer material 14, the height of the longitudinal material 12 can be accurately positioned and high precision can be maintained.

In addition, by making the base 24 itself movable in the above embodiment, it becomes possible to collect the devices in one place,
Building space can be used effectively. Further, the versatility for curved skin blocks having different curvatures is increased.

As explained above, according to the present invention, it is possible to easily and accurately position the aggregate, and it is possible to improve the workability and accuracy of the framework.
