The working principle of the automatic connecting and locking device for the large-scale cylinder section equipment provided by the invention is as follows:
during butt joint, the upper barrel 1 descends vertically and slowly, when the edge of the end part of the connecting end of the upper barrel 1 contacts the upper inclined plane of the centering rod 13, the centering rod 13 opens outwards under the action of the pressure of the upper barrel 1, the upper barrel 1 continues to descend, the upper barrel slides downwards along the upper inclined plane of the centering rod 13, the upper barrel 1 is gradually coaxial with the lower barrel 2 under the action of the tension spring 14 of the centering rod 13, until the spherical universal wheel 15 in the middle of the centering rod 13 contacts with the outer side barrel wall of the upper barrel 1, the upper barrel 1 continues to descend, the spherical universal wheel 15 rolls along the outer side barrel wall of the upper barrel 1, and the upper barrel and the lower barrel are guaranteed to be centered.
In the descending process of the upper barrel 1, the object limit boss 29 on the outer side of the connecting end of the upper barrel 1 is in contact with the second inclined surface 28 on one side of the V-shaped notch in the middle of the quadrant plate 6, when the upper barrel 1 descends again, the object limit boss 29 slides downwards along the second inclined surface 28 of the V-shaped notch of the quadrant plate 6, the upper barrel 1 rotates along with the object limit boss, and finally the quadrant boss enters the groove at the bottom end of the V-shaped notch of the quadrant plate 6 to ensure opposite quadrants of the upper barrel and the lower barrel.
During the descending process of the upper barrel 1, the teeth of the upper barrel 1 may not enter from the gaps between the teeth of the locking ring 3, but press the teeth of the locking ring 3, the upper barrel 1 continues descending, so that the locking ring 3 compresses the nitrogen spring 20, and the locking ring 3 descends under the pressure of the upper barrel 1 until the connecting end face of the upper barrel 1 is attached to the connecting end face of the lower barrel 2, and the butt joint is completed.
During locking, the electric cylinder 10 is powered on, the electric cylinder 10 contracts to drive the locking ring 3 to rotate, when the teeth of the upper barrel 1 enter gaps among the teeth of the locking ring 3, the locking ring 3 starts to rise under the elastic force of the nitrogen spring 18 until the inner inclined surface of the locking ring 3 is attached to the inclined surface of the limiting clamping ring 4, then the electric cylinder 10 continues to contract, the teeth of the locking ring 3 are gradually attached to the teeth of the upper barrel 1, and finally the electric cylinder 10 continues to contract to give inter-tooth pretightening force to complete barrel section connection. When unlocking is carried out, the electric cylinder 10 extends out, the locking ring 3 rotates reversely, the teeth of the upper barrel 1 are separated from the teeth of the locking ring 3, when the teeth of the upper barrel 1 are positioned in gaps among the teeth of the locking ring 3, the electric cylinder 10 stops moving, unlocking is completed, and the upper barrel 1 can be taken out.
