Description

[Detailed Description of the Invention] The present invention relates to a jig for assembling hull blocks in a shipbuilding hull factory.

At the point where the hull blocks are assembled, there is a surface plate made up of a number of cylindrical platforms arranged in a grid pattern.Since pipes are often used for these cylindrical platforms, this is usually called a pipe-type surface plate. There is. On this surface plate, the hull small blocks are assembled, or the small blocks are joined together, etc. The jig of the present invention is attached to this cylindrical base and used for joining the hull blocks.

Hull blocks are provided with ears that are extensions of parts of the blocks to provide a joining line with adjacent blocks. This is to place the weld line in a convenient position for welding work. Figure 1 is a conceptual diagram of a cross section of a ship, showing an example of the arrangement of blocks. 1 is a deck block, 2 is a side shell block, 2b is an extension of the shell part 2a of block 2, and the ear 2
In b, the joining lines 2 and 3 with the gunwale 3 are placed at a higher position than the deck 1a to facilitate welding. The joining between the small blocks is usually carried out by placing them upside down on a pipe-type surface plate, and the order in which they are joined is shown in the side view of FIG.

In Figure 2, 10 is a pipe-type surface plate, 11 is its base, and 12 is a cylindrical stand erected on this. Figure 1
1 shows a state in which the deck block 1 is placed upside down on several cylindrical bases 12, and the ship's side shell block 2 is suspended by a crane hook 40 and brought above the block 1. Figure 2 shows a cylindrical base 1 with legs 31.
With the block 2 landing with its ear 2b on the beam 30 attached to the ear 2b,
is horizontally positioned by a stopper 32 welded onto the bead 30. FIG. 3 shows a state in which the block 2 is rotated using the tip of the ear 2b as a fulcrum while lowering the crane hook 40, and is placed on the block 1. In this state, the blocks 1 and 2 are joined.

When performing such work, ear 2b of block 2
In the past, the beam 30 and the like of the members to be received were made of materials that were available for each work. This takes a lot of time to prepare and often results in wasted materials. Therefore, the present invention attempts to standardize and streamline work by developing a jig that can be easily attached to and removed from the cylindrical base 12 and whose height can be freely adjusted.

FIG. 3 shows a perspective view of the jig of the present invention, where 12 is the aforementioned cylindrical base, 22 is a horizontal arm attached to the cylindrical base 12, and the cylindrical base 12 is held by the cylinder 22a at its base. The arm 22 is also provided with several holes 22b arranged in a row in the length direction of the arm for attaching a post 23, which will be described later. 22c is the cylindrical base 1 of the arm 22
This is a fixing screw for 2. Reference numeral 23 denotes a column having a row of mounting holes 23a in the vertical direction, and its lower end is received by a jack 25 via a seat 24. Pillar 2
3 is assembled to the arm 22 in a cross shape through the mounting holes 22b and 23a of both. The corner 26 formed by the arm 22 and the post 23 is the ear 2 of the block 2 mentioned above.
receive b. That is, the arm 22 corresponds to the conventional beam 30 in FIG. 2, and the column 23 corresponds to the leg 31 and stopper 32. With such a configuration, the height of the arm 22 can be selected to any desired size, even when the arm 22 is under load, and the distance of the column 23 from the cylindrical base 12, that is, its attachment to the arm 22 The position can also be adjusted, albeit in stages.

By preparing several jigs such as those described above, preparations for assembling the blocks at the required locations on the pipe-type surface plate can be quickly completed.

[Brief explanation of the drawing]

Figure 1 is a cross-sectional view conceptually showing the block arrangement on the starboard side of a ship, and Figure 2 1, 2, and 3 are side views showing the order in which small blocks are joined on a conventional pipe-type surface plate. In 1, the deck block is placed upside down on a cylindrical base, and the inverted side hull block is carried up to the top. In 2, the side hull block is landed with its ears on the beam on the cylindrical base. state, 3
