Definitions

  • the present invention relates to a quick connector in particular for the elements of an extension tube for oil drilling at sea.
  • fittings of the bayonet type comprising a locking ring disposed outside the elements to be connected to the extension tube.
  • the invention relates to a quick connector comprising a female tubular element and a male tubular element fitting into each other, a locking ring provided with a crown of tenons which cooperates with a crown of tenons provided on one of the tubular elements and of the members for exerting in the axial direction a pre-tensioning tightening between the two tubular elements and the locking ring
  • a construction method is illustrated for example by FR-A- 2 376 990.
  • the female tubular element and the male tubular element form between them an annular groove open at its upper part and limited at its lower part by an axial bearing produced on the periphery of one of the tubular elements, said groove having a dimension sufficient to allow the introduction of the locking ring.
  • the tubular elements 3, 4 have flanges 7, 8 for fixing to the lower part and to the upper part of the extension tube, peripheral lines 9 which are fitted in a completely conventional manner to said tubes.
  • the female tubular element 3 internally comprises a ring of tenons 12.
  • a locking ring 13 provided at its lower part and externally with a ring of tenons 14.
  • the upper face of the locking ring 13 has teeth 15 cooperating with teeth provided below a ring 16 which surrounds the male tubular element 4 and which bears on the edge of the female element 3.
  • the connector also comprises members, designated by the reference 20, uniformly distributed around the male tubular element 4 and ensuring the blocking of said connector in the locked position.
  • Each blocking member 20 is constituted by a screw 21 mounted freely in rotation on a sole 22 fixed below the flange 7.
  • the sole 22 has an inclined face 23 and the screw 21 drives in translation a wedge wedge 24 which slides between the inclined face and the ring 16.
  • the pins 14 of the ring 13 pass between the pins 12 of the female tubular element 3.
  • the ring 13 rests on the axial surface 11 and the play between the pins 12,14 is sufficient to allow the ring 13 to rotate freely in the annular groove 10.
  • the ring 16 is turned a fraction of a turn to drive in rotation, by means of the teeth 15, the ring 13 so that the studs 14 are positioned below the studs 12.
  • the organs of blocking 20, still being in place, the screws 21 are successively rotated driving the bias wedges 24 in translation in the direction indicated by the arrow 30 in FIG. 2.
  • This translation applies, by the wedge effect of the bias wedges 24, d on the one hand an axial thrust directed downwards on the female tubular element 3 via the ring 16 and on the other hand an axial thrust directed upwards on the male tubular element 4 via the soles 22 and flange 7.
  • the ring 13 is wedged in the groove 10 between the two tubular elements 3, 4 and immobilized in this locking position by the crowns of tenons 12, 14. The coupling is therefore locked.
  • the release will be carried out by loosening the bias wedges 24 and the uncoupling by rotation of a fraction of a turn of the ring 13.
  • This arrangement allows a minimum of machining operations of the various elements and forms a compact assembly in which the rotating locking ring is well protected between two solid parts, which makes it possible to reduce the dimensions of the ring and consequently the size of the fitting, while allowing easy access to the seals sealing. Furthermore, it also allows a good distribution of the load around the circumference of the tubular elements, and very easily control the areas with high stress.
