<p>A device for the quick coupling of a pipe fitting to a flanged pipe is described, comprising a connection plate (13) rigidly fastened to one end (1) of the fitting so as to be axially approachable to the front of a terminal flange (12) of the flanged pipe, clamping wheels (15) revolving around their own axis and projecting frontally from said plate (13) in circumferentially distanced positions. Each clamping wheel (15) has a round shape with a cut (24) along a cord of circle in order to allow in an angular position with cord turned toward the axis of the coupling, and to prevent in all the other angular positions, the passage of the flange (12) of the flanged pipe between said wheels (15) for the mutual moving near and moving apart of the plate (13) and of the flange (12). Each clamping wheel (15) has in addition toward said plate (13) a helicoidal neck (25) capable to cause as a result of the rotation of the wheel (15) from said angular position to said other angular positions the front abutment engagement and the clamping of said flange (12) against said plate (13). Each wheel (15) is controlled by a pinion- endless screw unit (19) supported by a block (80) integral with the plate (13) and connectable with external control means.</p> |
