Definitions

  • the present invention relates to a drilling machine comprising a kelly suspended from a boom pivotally mounted on a chassis, a rotary table through which the kelly is axially movable, motor members provided in the rotary table for driving the kelly in rotation, and a rotary drilling tool, notably an auger, attached to the lower end of the kelly.
  • the rotary table In drilling machines of this type, the rotary table must be rigidly connected to the boom to allow it to withstand the very intense forces to which it is subjected during drilling operations. The need for such a link is however not satisfactory.
  • the torque generated by the rotation of the kelly can indeed be transmitted to the boom so that the drilling machine is constantly subjected to the action of overturning forces preventing it from operating in good conditions.
  • the height above the ground of the rotary table of current drilling machines is generally of the order of ten meters.
  • the existence of such a distance between the table and the ground has the disadvantage not only of limiting the stability of the machine but also of correspondingly reducing the possible depth of drilling.
  • the present invention proposes to remedy the drawbacks mentioned above and, to do this, it relates to a drilling machine of the aforementioned type which is characterized in that the rotary table comprises at least two lateral protuberances extending symmetrically relative to the longitudinal axis of the kelly, in that the chassis comprises two guide channels arranged one opposite the other so as to receive the protrusions, and that locking means are provided to immobilize the protrusions at any predetermined height in the guide channels.
  • This set of provisions by preventing the torque generated by the rotation of the kelly from being transmitted to the boom, makes it possible to transfer the overturning forces to the drilling axis and therefore improves the operation of the machine. It also makes it possible to bring the rotary table closer to the ground and to correspondingly increase the depth of the drillings likely to be carried out.
  • the locking means comprise racks provided on the opposite faces of the guide channels, toothed bodies provided on the protuberances and whose teeth correspond to those of the racks, the toothed bodies being positioned so as to face the racks. when the protrusions are inserted in the guide channels, and control means for achieving relative movement between the racks and the toothed bodies in order to engage their teeth.
  • the rotary table can thus be locked securely and quickly in the guide channels. Its height above the ground can also be easily adjusted according to the conditions under which the drilling must be carried out.
  • the racks are integral with the opposite faces of the guide channels while the toothed bodies are movable relative to the racks.
  • the control means are constituted by jacks mounted back-to-back in the protrusions so as to move the toothed bodies in the opposite direction.
  • the channels are carried by a cradle pivotally mounted on a frame secured to the chassis, around a horizontal axis perpendicular to the median longitudinal axis of the latter.
  • the boom comprises means for supporting a second tool extending, like the kelly, in the median longitudinal plane of the chassis, and is carried by a carriage movable on the latter, parallel to its median longitudinal plane.
  • Augers which have the advantage of working quickly, cannot drill more than 50 meters.
  • the machine according to the invention further comprises a weaving collar capable of enclosing a drilling tube whose axis is located in the median longitudinal plane of the chassis, jacks for communicating an alternating circular movement to the dart collar and to the drill pipe, jacks to drive the drill pipe into the ground while it describes its movement, and a retaining collar to support the drill pipe during its ascent.
  • the boom can advantageously support a clamshell bucket to evacuate the cuttings contained in the drilling tube.
  • the drilling machine which can be seen in FIG. 1 comprises a chassis 1 resting on tracks 2, an arrow 3 mounted on a carriage 4 movable on the chassis 1, parallel to the longitudinal axis thereof, a kelly 5 suspended by a cable 6 at the upper end of the boom, a rotary table 7 through which the kelly is axially movable, and an auger 8 installed at the lower end of the kelly.
  • the frame 1 comprises an anterior frame 9 in the extension of its longitudinal sides, this frame being made up of uprights 10 connected by spacers 11 and bearing on the ground by means of pads 12 controlled by hydraulic jacks 13. It furthermore comprises, in a manner known per se, a motor unit 14 and a central hydraulic unit 15.
  • the carriage 4 supports not only the boom 3, but also a control cabin 16, a first winch 17 on the drum of which is wound the cable 6, and a second winch 18, the cable 19 of which passes at the upper end of the boom and supports a drill bit 20. It furthermore comprises a hydraulic cylinder 21 and a turret 22 to pivot the boom first in the median longitudinal plane of the chassis and the second around a vertical axis contained in this plane.
  • the arrow 3 is provided on its front face with a bracket 23 intended to immobilize the rotary table 7 (see FIG. 6) when the auger 8 is not used or when the operator rotates the arrow 3 around the above-mentioned vertical axis for discharging the cuttings retained on the turns of the auger. It is made up of telescopic elements in the example shown, but it goes without saying that it could have a rigid structure.
  • the rotary table 7 has two lateral protrusions 24 extending symmetrically relative to the longitudinal axis of the kelly, on either side of the median longitudinal plane of the chassis.
  • the frame 9 internally supports a cradle 25 (visible in Figures 2 and 5) having on the inner faces of its longitudinal sides two guide channels 26 arranged one opposite the other to receive the protuberances.
  • Locking means 27 are also provided for immobilizing the protrusions 24 in the channels 26.
  • the locking means 27 comprise racks 28 fixed on the opposite faces of the channels 26, toothed bodies 29 housed in the faces of the protrusions 24 which are in front of the racks 28 when the table rotary is in place in the cradle, the teeth of the racks and of the toothed bodies being conformed to nest intimately with each other, and control means 30 able to move the toothed bodies 29 relative to the racks in order to lock or to unlock the protrusions 24 in the channels 26.
  • the channels 26 are each delimited by two square section tubes 31 fixed parallel to each other on the internal faces of the longitudinal sides of the cradle and providing a space which widens progressively at their upper part ( see Figures 1, 5 and 6) to facilitate the introduction of the protrusions 24 between them.
  • control means 30 are constituted by jacks 32 mounted back-to-back in the protuberances 24 and capable of moving the two toothed bodies 29 of the same protuberance in opposite directions.
  • the cylinders 32 are able to be connected to a source of pressurized fluid not shown by a single pipe 33 opening into their chamber on the bottom side or by two pipes 34 opening into their chamber on the rod side.
  • Their rod is coupled to the corresponding toothed body by means of a groupille 35, which allows them to apply the toothed bodies 29 against the racks 28 when a pressurized fluid is sent into their chamber on the bottom side or to move them away racks when the pressurized fluid is sent to their rod side chamber
  • toothed bodies 29 are guided in their movement by keys 36 visible in FIGS. 3 and 4, these keys being housed in complementary cavities formed in the facing faces of the protrusions 24 and of the toothable bodies displaceable in the latter .
  • the drilling machine according to the invention can be used for carrying out drilling inclined with respect to the vertical.
  • its cradle 25 is articulated on the frame 9 around a horizontal axis 37 perpendicular to the median longitudinal axis of the chassis 1 and can pivot under the control of two jacks 38 extending perpendicular to the axis 37.
  • the jacks 38 are articulated on the chassis 1 by the bottom of their cylinder and at the lower end of the rear transverse side of the cradle 25 by the free end of their rod piston. It will also be noted that the axis 37 is supported on the rear uprights 10 of the frame 9, above the connection of the jacks 38 with the cradle 25. It will also be noted that a support 39 has been installed at the free end of the bracket 23 in order to support the kelly 5 during the ascent of the auger 8 from the bottom of the borehole.
  • the machine according to the present invention can moreover be used to carry out ditching drilling. To this end, it comprises in a manner known per se a weaving collar 40 capable of enclosing a tube of drilling 41, two wandering jacks 42 to communicate an alternating circular movement to the collar 40 and to the tube 41, two working jacks 43 articulated on the longitudinal sides of the frame 9 and to which the collar 40 is suspended, and a retaining collar 44 for support the tube 41 during its ascent out of the borehole.
  • the weaving collar 40 is located below the lower end of the guide channels 26 of the cradle 25 and is lockable on the tube 41 by hydraulic jacks not shown. It can also be opened at its part which is directed towards the front transverse sides of the cradle 25 and of the frame 9, in order to facilitate the positioning of the tube 41 in the collar 40 as well as the removal of said tube. It is moreover for this purpose that the cradle 25 and the frame 9 are also open at their front transverse sides (see FIG. 2).
  • the drill pipe 41 is conventional and need not be described here. It will simply be specified that it is provided with a cutting bag at its lower end and consists of sections connected one after the other as they are inserted into the ground.
  • the wiggle jacks 42 are interposed between the frame 1 and two legs 45 projecting the wiggle collar 40 on the longitudinal sides of the frame.
  • the retaining collar 44 As for the retaining collar 44, it is articulated on the longitudinal sides of the frame 9 around a horizontal axis 46 and is lockable on the tube 41 by hydraulic cylinders not shown. Like the tack collar 40, it can be opened at its part which is directed towards the front transverse sides of the cradle 25 and of the frame, also to facilitate the positioning and removal of the tube 41.
  • a hydraulic servo not shown is provided to prohibit the opening of the retaining collar before the locking of the dart collar on the drilling tube and vice versa, so as to prevent the drilling tube falling back to the bottom of the hole drilling during its ascent.
  • the drilling machine also comprises a grab bucket 47 for discharging the cuttings accumulating in the drilling tube 41.
  • This bucket which can be seen in FIG. 6, is hooked to the free end of the cable 19 and must extend coaxially with the tube 41 into which it is necessary to introduce it to allow it to take the cuttings.
  • the kelly 5 is made up of a rod with a square section but to allow drilling up to fifty meters to be carried out, it could be made up of several telescopic elements; .
  • the Kelly's rotary drive is provided in a manner known per se by two hydraulic motors (not shown) housed in the rotary table; .
  • two vertical cylinders 48 located on either side of the kelly 5 are interposed in a manner known per se between the upper part of the rotary table 7 and an annular support 49 surrounding the kelly, in order to transmit the auger force of penetration into the ground; and .
  • the protrusions 24 of the rotary table are provided on their upper and lower faces with arches 50 (see FIG. 4) intended to cooperate with the racks 28 to improve the guiding of the rotary table during its movement along the channels 26 .
  • drill bit 20 could advantageously be used. It would suffice to immobilize the rotary table 7 against the underside of the jib and to move the carriage 4 on the frame 1 of the crane so as to position the drill bit in the axis of the borehole, which would require very little time.
