Definitions

  • the present invention relates to a power plant with jacks for producing the continuous movement of an oblong object in the direction of its axis, and / or for moving an element along said object.
  • axis we mean the general direction in which s extends said object, and not necessarily an axis in the geometric sense of the term, that is to say an axis of revolution or symmetry.
  • the object in question can constitute any mobile mechanical member, for example a hoisting member, the installation in question then being fixed.
  • it can be fixed (post), in which case the installation in question is mobile along this object and can in turn entail, for example to hoist it, any element.
  • a power plant with cylinders is characterized in that it comprises, on the one hand at least two sets of cylinders, the piston or pistons of each set being associated with locking means capable of selectively, momentarily and automatically joining them to said object, their body being fixed (in the case of a movable oblong object) or mobile and made integral with an element to move along said object (in the case of a fixed oblong object), and on the other hand a device for supplying the bodies of jacks with hydraulic fluid, provided with automatic control means (pumps; electro-valves; detectors position; amplifiers etc) of the fluid supply or evacuation on either side of said pistons, the arrangement and operation of the aforementioned locking and control means being ensured in such a way, at least, that the taking up of said object by the piston or pistons of one of the cylinder assemblies are carried out without discontinuity at the time when the piston or pistons of the other cylinder assembly cease their own
  • general rocking movement is meant to indicate that, in general, the piston or pistons of one of the cylinder assemblies go up while the piston or pistons of the other set go down, and vice versa, these movements being synchronized. It is in any case conceivable that thanks to such an installation, it is possible to obtain an essentially continuous and smooth movement of the object or other mobile element, the piston or pistons of a set of jacks relaying the piston or pistons of the 'other set, without any interruption, by exerting their motive force on the object or element to move, from 4 ue this or these pistcns of the other set cease to exert this force.
  • the invention may include other provisions, in particular to allow a rocking movement perfectly synchronized between said pistons of the cylinder assemblies, and to allow easy blocking on the object, and in particular the installation above defined under its the most general form may also be characterized, for this purpose, in that the arrangement and operation of said locking and control means are also ensured in such a way that the start of an empty movement of the piston or pistons d 'one of the cylinder assemblies in the direction of relative movement of said object with respect to this assembly, and their blocking on the object, are automatically controlled in an instant preceding the arrival at the end of the race, under load, and moving in the same direction, of the piston or pistons of the other cylinder assembly.
  • period of time which elapses between this start of treatment and the instant in question may correspond approximately to the time necessary to ensure release at the end of the race under load. This will also be better seen later.
  • any embodiment adapted to the problem posed and in particular that it comprises two sets of cylinders each comprising a annular piston surrounding said oblong object, the two pistons being mounted in a common cylinder body also annular and surrounding said object.
  • This arrangement advantageously makes it possible to obtain a compact and robust installation, and also allows a simplification, the chambers of the two sets of jacks being able to communicate directly inside the common jack body.
  • One can also facilitate, in this way, the mechanical connection (by bolts or the like) between the pistons and the oblong object.
  • the installation comprises two sets of jacks each comprising an annular piston surrounding said object. oblong, the two pistons being mounted in two separate cylinder bodies, also annular, coaxial and surrounding said object.
  • FIG. 1 there is referenced at 1, in the form of a tube, the oblong object which it is desired to subject to a continuous displacement in the direction of its axis 2.
  • the cylinder assembly comprises in this example two jacks having a common body 3 mounted, on a fixed support 4, so as to surround said tube 1.
  • the body 3 consists of two cylindrical and concentric walls 3a and 3b connected at both ends by bottoms 3c and thus defining in the body 3 a common annular chamber 5.
  • the diameter of the inner tubular wall 3a is slightly greater than that of the tube 1.
  • annular chamber 5 In the annular chamber 5 are slidably mounted two annular pistons 6 and 6 'each extended by a tubular part, respectively 7 and 7', leaving the common body 3 by the two ends of the latter and each of which carries means for the end blocking, respectively 8 and 8 '.
  • These means can be constituted by any means suitable for temporarily locking the corresponding tubular part 7 or 7 'on the tube 1; it may, for example, be locking means comprising pins or the like, respectively 9 and 9 ′, adapted to move radially towards the axis 2 or in the opposite direction, either to be able to engage in a light or the like 10 of the tube is to be able to disengage from it, it being understood that the lights 10 can be distributed at constant spacings both according to the length of the tube and along its periphery.
  • the circuit for supplying the chamber 5 with hydraulic fluid has been shown very schematically. It comprises in particular pipes 17 and 17 'opening at the two ends of the chamber, crossing the bottoms 3c, and a pipe 18 opening into the central part of the chamber crossing the cylindrical wall 3b, these various pipes being able to be placed in communication with pumps 19 and 19 'via valves, respectively 20 to 23 and 20' to 23 ', these valves being connected according to the arrangement indicated in the drawing.
  • the position, in the direction of the axis 2, of the pistons 6, 6 'in the chamber 5 can be determined by means of position detectors (not shown) and which make it possible to determine the instants at which these pistons arrive, for the piston 6 at the levels indicated by the lines N1, N2, N3 and N4, and for the piston 6 'at the levels indicated by the lines N'l, N'2, N'3 and N'4.
  • FIG. 4 time is shown on the abscissa and the position of the pistons 6, 6 ′ along the ordinate in the direction of the axis 2.
  • the parts in reinforced line of the two diagrams represented in this figure designate the displacements of the pistons in load, that is to say when by means of pins 9 or 9 'they exert a thrust (which will be assumed directed upwards in FIG. 1) on the tube or other oblong object 1.
  • valves 20 and 22 are simultaneously closed to again drive the piston 6 upwards and at the same time the locking of the spindle 9 on the corresponding light 10 (reference B).
  • valves 21 ′ and 23 ′ are automatically closed, which causes the piston 6 ′ to descend.
  • FIG. 4 the operational interconnections between the controls of the pistons 6 and 6 ′ have been shown diagrammatically in the form of dashed vertical lines I, II and III.
  • Line I clearly shows that the taking over of the tube 1 by the piston 6 'immediately follows the end of the taking over of this tube by the other piston 6, as well as the taking over of the tube by the piston 6 immediately follows the end of the support of this tube by the piston 6 '.
  • Line II shows that when a piston arrives under load at level N2 or N'2, it automatically controls the start of the rise of the other piston and its locking relative to the tube 1.
  • line III shows that when a piston arrives under load at level N3 or N'3, it automatically controls the start of the descent with no load from the other piston.
  • the object 1 may in particular be an object to be hoisted, or on the contrary an object to be lowered, for example to sink it into the ground, to effect sinking, drilling or the like.
  • This object l instead of being mobile, as in the example which has just been described, could also be constituted by a fixed post, and in this case of course, it is the common cylinder body 3 which is would likewise move in a perfectly continuous manner along the object 1, by driving any element, for example an element to hoist to the top of the post or the like.
  • Many applications of this type can be envisaged in particular in the technique of oil drilling, and in particular but not limited to the hoisting of self-elevating platforms for exploration or exploitation at sea.
  • the object 1 can be of the same type as according to Figure 1, there are provided two separate cylinder bodies 24 and 24', annular, surrounding the oblong object 1 and in each of which is mounted a piston also annular, respectively 25 and 25 '.
  • the means for supplying the two separate cylinder bodies with hydraulic fluid may be of the same type as those which have been previously described and they have been referenced globally at 26 for the body 24 and 26 'for the body 24'.
  • Operation may in any case be similar to that which has been described with reference to FIG. 1.
  • this object can be arbitrary and is referenced in Figure 3 locking means 31 and 31 'of the type with clamps. Of course, it will to use collars whose tightening on the object 1 and loosening can be controlled automatically from appropriate control signals, for example electrical or hydraulic.
