The cylindrical tank shown in FIGS. 8 to 10 shows a so-called C-type cylindrical tank in which both ends in the axial direction are closed with a hemispherical or bowl-shaped head.

Since most of the large cylindrical tanks, including the C-type cylindrical tank, are huge, as shown in FIG. It is manufactured by dividing into (6), and after joining the stiffener 4 as a reinforcement inside the single shell pipe 2, several shell single pipes 2 and the heads 6 on both sides are connected by welding to assemble.

Conventionally, even if the welding operation of a cylindrical tank is complicated and manufactured by hand or automated, only welding equipment is separately provided for each unit process and welding is performed.

For example, the dedicated welding equipment for welding the outer periphery connection of the single shell pipe 2 cannot be used to weld the inner periphery of the single shell pipe 2, so the operator enters the inside of the single shell pipe and performs welding manually. It is difficult to secure quality.

In addition, the dedicated welding equipment for welding the stiffener inside the single shell pipe can be utilized to weld the inner peripheral connection of the single shell pipe together with the stiffener welding, but cannot weld the outer peripheral connection of the single shell pipe.

In addition, the equipment for each process as described above, when the shell single pipes are continuously connected, it is difficult not only to stably support the elongated shell single pipe, but also to precisely match the new shell single pipe and the already welded shell single pipe.

In welding assembly of the cylindrical tank, at first, using a crane, one shell end pipe 2 is placed on the loading and rotating bogie mechanism 120 and the aligning and supporting mechanism 130 (loading).

Then, by operating the hydraulic ram 138 of the alignment and support mechanism 130 to raise and lower the lifting roller 134 , the shell end pipe 2 is leveled.

Next, the traveling bogie 220 of the welding manipulator mechanism 200 is transferred along the second traveling rail 210 to the shell end tube 2 side, and the vertical position of the horizontal arm 240 is adjusted to make the two first weldings. The traveling block 252 so that the welding torches 250a and 250a of the head 250 are properly positioned at the T-shaped connection portion (welding line) w2, which is the connection between the both sides of the stiffener 4 and the inner circumferential surface of the shell end tube 2 ) to adjust the front-rear position and the vertical position of the first welding head 250 .

Then, welding to the stiffener 4 is performed while rotating the shell end pipe 2 by driving the rotation driving roller 124 of the loading and rotating bogie mechanism 120 .

The shell end pipe 2 on which the stiffener 4 is welded is rearward (that is, the 'shell end pipe connection working direction in FIG. 7 ) within the range that its front end does not exceed the rear alignment and support mechanism 130 . to move it (at this time, with the help of a crane). The rear end portion is positioned over and supported by the transport and rotation mechanism 140 .

Next, another shell end pipe 2 is lifted using a crane and placed on the loading and rotating bogie mechanism 120 and the front alignment and support mechanism 130 (loading).

Next, by performing the operation as described above, the stiffener 4 for the newly loaded single shell pipe 2 is first welded, or the inner and outer periphery welding of the two adjacent shell single pipes 2 is performed first. When the welding operation of the stiffener 4 for the newly loaded single shell pipe 2 is first performed, the inner and outer periphery welding operations described below are subsequently performed, and the inner and outer periphery welding operations are performed first. After performing the inner and outer periphery welding work described below, the welding work of the stiffener 4 described above is performed.

In the inner and outer periphery welding operation between the two adjacent shell single pipes 2, the inner and outer peripheral connecting portions w1 of the two adjacent shell single pipes 2 are interposed therebetween, and the front and rear alignment and support mechanisms 130 are The position is adjusted by moving the two shell end tubes 2 to be positioned or by moving the alignment and support mechanism 130 .
