The principle of the operation of the large tubular member automatic connection tightening device provided by the present invention is as follows.

At the time of abutting, the upper cylinder 201 gradually descends in the vertical direction, waits until the peripheral edge of the end of the connection end of the upper cylinder 201 comes into contact with the inclined surface of the centering lever 213, and the centering lever is driven by the pressure of the upper cylinder 201. The upper cylinder 201 spreads outward, the upper cylinder 201 continuously descends, the upper cylinder slides downward along the inclined surface of the centering lever 213, and the tensioning action of the tension spring 214 of the centering lever 213 causes the upper cylinder 201 to gradually move downward. The upper cylinder 201 is continuously lowered until the ball-shaped universal wheel 215 in the centering lever 213 comes into contact with the outer cylinder wall of the upper cylinder 201, and the ball-shaped universal wheel 215 is on the outer side of the upper cylinder 201. It is possible to secure the centering of the upper cylinder and the lower cylinder by sandwiching the upper cylinder while rolling on the cylinder wall.

As the upper cylinder 201 descends, the quadrant-specific convex portion 229 outside the connecting end of the upper cylinder 201 contacts the second inclined surface 228 of its one side in the "V" -shaped notch in the quadrant plate 206, and continues. Upon descending, the quadrant-specific convex 229 slides along the second inclined surface 228 of the "V" -shaped notch in the quadrant plate 206 so that the upper cylinder 201 rotates with it, and finally the quadrant convex is the quadrant plate 206. It is possible to enter the bottom end groove of the "V" -shaped notch in the above and ensure that the upper cylinder and the lower cylinder have quadrants specified.

When the upper cylinder 201 is lowered, the teeth of the upper cylinder 201 may be pressed against the teeth of the tightening ring 203 without entering through the gap between the teeth of the tightening ring 203. Then, the upper cylinder 201 is continuously lowered until the connection ends of the upper cylinder 201 and the lower cylinder 202 are bonded and abutted, the nitrogen gas spring 220 is compressed by the tightening ring 203, and the tightening ring 203 is pressed into the upper cylinder. It is lowered by the pressure of 201.

When a current flows through the electric cylinder 210 during tightening, the tightening ring 203 is interlocked to rotate due to the compression of the electric cylinder 210, and the tightening ring is operated until the upper cylinder 201 teeth enter the gap between the teeth of the tightening ring 203. The 203 is raised by the elasticity of the nitrogen gas spring 18, and the inclined surface inside the tightening ring 203 is bonded to the inclined surface of the position limiting engaging ring 204. Next, the electric cylinder 210 is continuously compressed, and the tightening ring 203 teeth and the upper cylinder 201 teeth are gradually bonded to each other. Finally, when the electric cylinder 210 is continuously compressed and a pretension force is applied between the teeth, the connection to the tubular member is completed. When releasing, the electric cylinder 210 is extended, the tightening ring 203 is rotated in the opposite direction, the teeth of the upper cylinder 201 are separated from the teeth of the tightening ring 203, and the teeth of the upper cylinder 201 are in the gap between the teeth of the tightening ring 203. When it is positioned, the operation of the electric cylinder 210 is stopped, the release is completed, and the upper cylinder 201 is removed.
