CA 2516395

A device for the quick coupling of a pipe fitting (50) to a flanged pipe is described. The device comprises a coupling plate (13) that is rigidly fastened to one end of the fitting so as to be axially approachable to the front of a terminal flange (12) of the flanged pipe, at least three locking wheels (15) rotatable around their own axes and projecting frontally from said plate (13) in circumferentially spaced positions and remotely controllable means (19) for controlling the rotation of said rollers (15) around their own axes. Each locking wheel (15) has round shape with a cut (24) along a circle chord in order to allow in one angular position with the chord facing the axis, and to prevent in all the other angular positions, the passage of the flange (12) of the flanged pipe among said wheels (15) for the reciprocal approach and the movement away of the plate (13) and the flange (12). Each locking wheel (15) has in addition, toward said plate (13) a helical neck (25) that is capable to cause, as a result of the rotation of the wheel (15) from said one angular position to said other angular positions, the front abutment engagement and the locking of said flange (12) against said plate (13).

L'invention concerne un dispositif pour coupler rapidement des raccords de tuyauterie (50) à un tuyau à bride. Le dispositif comprend une plaque de couplage (13) qui est fixée de manière rigide à une extrémité du raccord, de façon à s'approcher de façon axiale vers l'avant d'une bride terminale (12) du tuyau à bride, au moins trois roues (15) de verrouillage rotatives autour de leur propre axe et faisant saillie de manière frontale à ladite plaque (13) dans des positions espacées de manière circulaire, et des moyens (19) pouvant être commandés à distance, destinés à commander la rotation desdits rouleaux (15) autour de leur propre axe. Chaque roue (15) de verrouillage présente une forme ronde avec une découpe (24) le long de la corde du cercle, ce qui permet de les positionner dans une position angulaire avec la corde faisant face à l'axe, et d'empêcher, dans toutes les positions angulaires, le passage de la bride (12) du tuyau à travers lesdites roues (15) lors d'un rapprochement réciproque et le mouvement arrière de la plaque (13) et de la bride (12). Chaque roue (15) de verrouillage présente, de plus, vers ladite plaque (13) un col (25) hélicoïdal pouvant provoquer, en tant que résultat de la rotation de la roue (15) d'une position angulaire dans d'autres positions angulaires, l'enclenchement de butée avant et le verrouillage de ladite bride (12) contre la plaque (13).
