<p>PURPOSE:To assemble a multiple cylindrical vessel simply and speedily, yet in an accurate manner, by using a circular sectional rail being set up in making it accord with a shaft center of the existing outer cylinder as a guide, while assembling the vessel from a large diametral inner cylinder drawn in to the outer cylinder in regular sequence. CONSTITUTION:A rail 7 is positioned right so as to accord with the shaft center of an outer cylinder 5 being so far installed, while an inner cylinder 6 is fitted in the rail 7, attaching both ends of a relay rope 11 to a holding device 3 for the inner cylinder 6, and a bending part of the relay rope 11 is connected to a driving device 2 upon inserting the outer cylinder. And, the rope 11 is drawn nearer with the driving device 2 and then the inner cylinder 6 is drawn into the inside of the outer cylinder 5. With this constitution, since the rail 7 serving as a criterion for assembling exists there, a multiple cylindrical vessel can be assembled simply and speedily, yet in an accurate amnner.</p> |
