<p>PROBLEM TO BE SOLVED: To surely connect matching pipe groups together by absorbing a positional deviation between a center pin and a center pin hole and between a plurality of coupling plates by means of a freely movable supporting mechanism in equipment moving audience seats and the like suitably for a usage objective game event. SOLUTION: A coupling plate 16 is lowered via a screw jack 4 by means of a servomotor 3 arranged in a frame 1 on the movable side. A center pin 27 on the coupling plate 16 side is lowered by means of a hydraulic cylinder 29 so as to be inserted into a center pin hole 41 on the fixed side, and then, a coupling plate 33 on the fixed side is moved within the horizontal plane by means of a supporting mechanism so that respective axial centers are matched with each other. Subsequently, respective lock pins 30 are inserted into matching lock pin guides 41 individually for matching an angle, while the coupling plate 16 is lowered further so as to connect male with female pipe joints arranged conformably with both coupling plates 16, 33 to each other.</p> |
