Definitions

  • the invention relates to a quick connection device for solid rods, tubes of any diameter and casings particularly suitable for assembling risers, casings even of large diameters for drilling at sea, and stacks of anchoring of oil platforms.
  • a high precision of the assemblies is thus necessary in order to prevent the risks of fatigue and rupture of assemblies which are insufficiently tight or liable to loosen.
  • threaded connectors allowing excellent connection, but they have the drawback of requiring a rotation of at least two and a half turns before tightening the connected elements, which is always a relatively long operation and difficult to carry out on the supports. floating, as soon as the diameter of the connectors exceeds 60 cm.
  • Another embodiment consists in interrupting the steps of a circular threading or grooving on equidistant sectors, so as to make the connection by simple axial bringing together of the tubular elements then by rotation of a fraction of a turn of an element by compared to each other.
  • the connection is thus made on several series of portions of threads or grou.rages in the manner of a bayonet assembly.
  • the milling operations required by such a connector are very expensive.
  • the peripheral discontinuity of the assembly gives it limited mechanical characteristics.
  • the object of the invention is a device for quick connection of rods, tubes, casings and sections of anchor piles, in particular for drilling at sea, comprising a male part and a female part, of the type with helical grooves conical clamping.
  • each part is provided with a plurality n of grooves of constant profile and complementary to that carried by the other part, the apex of each of these grooves being, seen in axial section. , offset radially from the top of the adjacent grooves by a value at least equal to the fraction ri of the variation in the radius of the conical surface carrying said grooves on a helical pitch.
  • each of the grooves of the above-mentioned plurality is of sufficient length to cut at least twice a generatrix determined for each grooving of said conical surface.
  • the arrangement according to the invention has the same advantage as the connectors with bayonet assembly mentioned above, that is to say providing a complete tightening by axial approximation followed by a rotation of a fraction of a turn without having any the drawback, namely the discontinuity in the distribution of forces in the connector, due to the presence of the sectors without threads
  • the invention makes it possible to avoid expensive machining operations such as the necessary milling of the threaded couplings interrupted according to the prior art.
  • the invention also makes it possible to generate, at the end of tightening, a significant prestress in the assembly, making it possible to dispense with the use of positive locking devices for the parts together.
  • the implementation of these devices has the drawback of reducing, or even eliminating, the tightening preload and, thereby, reducing the resistance of the connection devices facing alternating forces.
  • the invention makes it possible to avoid the loss of these devices during the transport of the tubes or the connectors.
  • the female connection piece can serve as a means of tightening a tubular connection on a well head.
  • the male connection piece can be the well head which for this purpose has on its conical external part n threads or grooves.
  • the female connecting piece has on its inner surface, beyond the threads, a profile adapting to the tubular connection carrying the body of the jacks, the ends of their rods being connected to the female piece for its rotation.
  • each grooving can include a set of threads (at the top and bottom of the grooving) the variation in nominal diameter of which is identical.
  • the grooving can be a simple triangular or trapezoidal section thread. It will however be preferred that the sides of this grooving are such that the trace of the lower side for the male part and the upper side for the female part, in an axial plane, intersects the axis of the assembly mounted female part at the top, above its radial level.
  • connection device of FIGS. 1 to 4 comprises a female part 1 and a male part 2.
  • these parts are connected by means of four helical grooves designated 3, 4, 5 and 6 for the female part and 3 ', 4', 5 'and 6' for the male part.
  • each grooving of the part 1 consists of an inclined flank 10 connecting at its lower part to a flank 11 slightly inclined upwards in the direction of the axis and ending in its upper part with the inclined part 11 of another grooving by a small vertical portion 12.
  • Each groove is produced on a common conical surface 7 whose conicity is such that, in the radial plane of the figure, the apex 12 of each groove is offset radially with respect to the apex of the adjacent grooves by a value a at least equal to the traction J of the variation in radius VR of the conical surface 7 along a helical pitch, n being the number of grooves used (here 4).
  • each grooving of the part 2 adapts to that of the grooves of the part 1, so that, during the simple axial displacement of the female part 1 relative to the male part 2, the grooves 3, 4, 5, 6 are applied by their side 10 on the corresponding side of the grooves 3 ', 4', 5 'and 6' of the male part 2, as shown in FIG. 2.
  • a tight contact is thus produced throughout each of the four threads, each extending over at least one complete revolution.
  • the assembly produced then has a homogeneous mechanical resistance over its entire surface, capable by the prestressing carried out of withstanding numerous operations - even flapping - without loosening.
  • a seal 8 has been shown in a groove in the part 2. At the end of the connection by rotation, the seal 8 slides on the vertical part 9 of the part 1.
  • FIGS. 5 and 6 we see two possible variants of grooves, one (FIG. 5) in the form of new trapezoidal threads, the other (FIG. 6) in the form of groups of threads 15, 16, 17, 18 evolving. on nominal helical surfaces 15 ′ ... offset radially under the same conditions as the grooving vertices of FIG. 4.
  • connection device can be very numerous and in particular to provide the connector function, that is to say a device that can be controlled remotely in the connection or disconnection direction.
  • FIGS. 7 and 8 show two connection devices, one composed of the multiple threaded pieces 24 and 25, the other of the multiple threaded pieces 26 and 27.
  • the female connection piece 26 can be made integral with a well head receptacle 28 or be incorporated into it by any known means.
  • the male part 27 surrounds the well head 25 and its lower end serves, after tightening and locking, as a stop for a flange 29 of the well head 25.
  • the upper part of the high pressure wellhead 25 comprises a multiple thread with 8 threads for example and is surrounded by the connecting piece 24.
  • This piece belongs to a set 30 and has a groove surrounding its multiple threads surrounding the flange 31 of the same assembly 30 serving as a hydraulic connector.
  • the assembly 30 also includes the flanges 32, 33, 34 and 35 used for fixing vertical axes, such as 36, for example supporting the bodies of jacks 37.
  • the rods 38 of these jacks have their ends fixed to vertical axes, such as 39 adjoining the flanges 40 of the connection piece with multiple threads 24. It is therefore sufficient to order the jacks 37 so that the rods 38 cause the connection piece 24 to rotate by one eighth of tower.
  • connection device 24, 25 is held in tightness by the blocking produced by the control of the jacks 37. It is thus easy to repeat the connection and disconnection of the well head.
  • the tube 60 has for this purpose on its external upper part six threads, for example on which tighten six threads carried on the connecting piece 70.
  • This connecting piece like the piece 24 of the previous example already belongs to a set which is this time that of the lower part of the tube 80.
  • An extension 49 of the tube 60 without thread allows after tightening of the connecting piece 70 to be applied laterally against a sealing ring 50 disposed in a groove of a lower extension of the flange 42 of the tube 80 supporting the piece of connection 70.
  • the tubes 60 and 80 respectively have flanges 43 and 44 used for fixing the sleeves such as 45 for the passage of the guide lines 46.
  • connection device described can be applied to any rapid connection of tubular elements, the prestressing of the threads obtained at the end of tightening of the elements not being affected by the possible locking connection when this is made necessary either during use involving a torque in the opposite direction to that of the tightening torque, or during of use requiring high security against loosening.
  • connection between the connected parts by means of threads undergoing prestress at the end of tightening after a rotation of a fraction of a turn is suitable for the use of the connected parts. It follows that if it is necessary to separate and then reconnect tubes such as 60 and 80 by means of the connecting piece 70 can be used as connecting means between the tube 60 and the connector 70 the device shown figure 11.
  • the lever 55 secured to the yoke 51 rotating in its support 90 mounted on the connector 70 is located horizontally and on the side opposite the cleat 54 secured to the flange 43 of the tube 60.
  • a lever 52 freely rotating around the axis 56 carried by the yoke 51 is retained by the edge 53 of an excess thickness thereof. Under these conditions, the lever 52 is horizontal and opposite the lever 55.
  • the invention makes it possible, by a clever combination of the dimensions of the diameter of the connector, the thread pitch and the taper of the nominal surfaces, to preserve the self-locking characteristics of the connections by conventional thread and therefore to create prestresses. while keeping the advantages of a coupling by bayonet.
  • the provisions of the invention also apply to the connection of solid rods in multiple applications and in particular to the constitution of anchoring stacks for oil platforms.
