Definitions

  • the invention relates to a rotary drive arrangement for a drill string with an outer pipe and an inner rod running at least in sections inside the outer pipe, in particular for double-head and/or overlay drilling, with a first gear for driving the inner rod in rotation and a second gear for driving the outer pipe in rotation, wherein the first gear and the second gear are independent of each other, according to the preamble of claim 1.
  • Such a rotary drive arrangement is, for example, from EP 1 936 109 B1 known.
  • an overall compact structure is achieved in that a total of three rotary drives are provided above an approximately ring-shaped gear unit for driving the inner linkage.
  • An annular gear unit for driving the outer pipe is spaced below the gear unit for the inner pipe.
  • the spaced gear units are connected to one another via struts.
  • Such rotary drive arrangements are used in drilling equipment for driving a drill string for double-head drilling or overburden drilling.
  • the drill rod has an inner rod with a drilling tool and an outer tube coaxially surrounding the inner rod with a further annular drilling tool.
  • the inner linkage and the outer tube can be driven in the same or in opposite directions with the same or a different torque and speed. In this way, boreholes can be created in the ground or in rock in an efficient manner.
  • the invention is based on the object of specifying a rotary drive arrangement for a drill rod which, with a compact structure, enables particularly efficient use.
  • the rotary drive arrangement according to the invention is characterized in that the first gear and the second gear are mounted in a common gear housing and are surrounded by it.
  • the rotary drive assembly When pulling the drill string out of a well, the rotary drive assembly must be retracted by means of a pulling device, usually a winch. Thus, a reduction in the weight of the rotary drive assembly also results in a reduction in the pull load, allowing greater pull force to be applied to the drill string and hence more efficient drilling operations.
  • a preferred embodiment of the invention is that the gear housing has a central support, which runs approximately perpendicular to the drilling axis and divides the gear housing into a first gear chamber, which faces away from the drilling tool side, and a second gear chamber, which faces the drilling tool side.
  • the two transmissions can be further arranged functionally separately from one another, with the two-sided arrangement of the transmission on the A good force distribution is achieved in the center support, which leads to a particularly stable housing structure.
  • the center support has a passage for the inner linkage.
  • the inner linkage can protrude further backwards through the center support from the drilling tool side.
  • the two transmission chambers can be fluidly connected via the passage, for example for a common transmission oil filling.
  • the gear housing can be sealed off from the inner linkage by a simple sealing device.
  • the gear housing can be sealed on the drilling tool side by a sealing device in relation to the inner rod assembly and on the other hand with a further sealing device in relation to the outer rod assembly or the output unit for the outer rod assembly.
  • the first gear for driving the inner linkage is arranged in the first gear chamber and the second gear for driving the outer tube is arranged in the second gear chamber.
  • the inner linkage being displaceable relative to the outer tube, with the inner linkage being able to be moved to the rear relative to the transmission housing. Due to this displaceability of the inner rod relative to the outer pipe, a drilling tool on the inner rod relative to a drilling tool on the outer rod can be arranged at the same level or—depending on the respective drilling method—therefore leading or lagging behind.
  • the compactness of the rotary drive arrangement is further improved in that the gear housing has at least one first inlet opening for at least one first drive shaft of at least one first rotary drive and at least one second inlet opening for at least one second drive shaft of at least one second rotary drive.
  • two drive shafts are provided for the outer tube and one drive shaft for the inner rod.
  • two or more drive shafts can also be provided for the outer tube and the inner linkage.
  • the inner linkage could also are driven by two drive shafts, while the outer tube is only driven by a single drive shaft.
  • the at least one first inlet opening is on one side of the center support and that the at least second inlet opening is formed on an opposite side of the center support in the transmission housing.
  • the entry openings for the drive shafts in the gear housing are preferably located in the gear housing in an area which lies between the drilling axis and the mast or the carriage on which the rotary drive arrangement is arranged.
  • the first gear has a first spur gear and/or the second gear has a second spur gear, which are each rotatably mounted in the gear housing.
  • the respective spur gear can be in meshing connection via a corresponding toothing on a drive pinion of the respective drive shaft.
  • a first output element is arranged on the first spur gear wheel for driving the inner linkage, which is connected to the inner linkage in a rotationally fixed but axially displaceable manner.
  • External teeth are thus formed on an outside of the inner linkage with a certain axial extension, which is longer than a width of the spur gear, with an axial displacement of the first spur gear relative thereto being made possible. This allows the inner linkage to be axially displaced relative to the first gear while at the same time continuing to transmit torque.
  • a further preferred embodiment of the invention consists in that a second output element is attached to the second spur gear for driving the outer tube, to which the outer tube can be attached in a rotationally fixed manner.
  • the second output element is in particular a flange-like connecting element to which an outer pipe, in particular a drill pipe, can be detachably attached.
  • a particularly compact structure is also achieved in that the gear housing is arranged on a base plate which the rotary drives are also arranged.
  • the rotary drive arrangement can thus be provided as a unit together with the rotary drives.
  • a further preferred embodiment of the rotary drive arrangement according to the invention consists in a displacement device being arranged on the outside of the transmission housing, which is axially fixed but rotatably connected to the inner linkage for the axial displacement of the inner linkage relative to the transmission housing.
  • the displacement device can in particular have an actuating cylinder, in particular a hydraulic actuating cylinder.
  • the displacement device is supported on the one hand on the transmission housing and is firmly connected to it.
  • the displacement device is preferably connected to the rotationally driven inner linkage via a rotary bearing, so that the inner linkage can be rotated further relative to the displacement device.
  • the displacement device is preferably located on the rear side of the gear housing facing away from the drilling tool side.
  • the invention further comprises a drilling device with a mast or a carriage, along which a drilling drive carriage is slidably mounted, the rotary drive arrangement according to the invention being arranged on the drilling drive carriage, in the manner described above.
  • the drilling drive carriage is slidably mounted by means of a cable system or actuating cylinders along a vertical mast or a carriage that can be adjusted in space about a number of axes.
  • the rotary drive arrangement can be arranged with the base plate together with the rotary drives on the drilling drive carriage.
  • the invention is explained in more detail below using a preferred exemplary embodiment, which is illustrated in the attached drawing.
  • the drawing shows a schematic cross-sectional view through a rotary drive arrangement according to the invention.
  • the rotary drive assembly 10 shown is used to drive a double drill string, not shown, about a drilling axis 5, with only part of the inner string 12 being shown. Further inner rod elements can be detachably attached to the inner rod 12 on one side of the drilling tool via a connecting section 14 . Coaxial with respect to the drilling axis 5 not shown outer tube to a Verbindngselement 56 of the rotary drive assembly 10 are releasably connected.
  • the rotary drive arrangement 10 comprises a gear housing 20 with a central support 22 which is formed along a central plane 21 which is orthogonal to the drilling axis 5 .
  • the central support 22 is firmly connected to a base plate 26, with which the rotary drive arrangement 10 can be fastened, for example, to a drilling drive carriage, not shown, of a drilling device.
  • a peripheral wall section 24 running on both sides is formed on the central support 22, to which a first side cover 25 is connected on a rear side facing away from the drilling tool, a first gear chamber 31 with a first gear 40 for driving the inner rod 12 being enclosed.
  • a second side cover 28 is attached to the peripheral wall portion 24, by which a second gear chamber 32 is enclosed with a second gear 50 for driving the outer tube.
  • the center support 22 has a centrally located passage 30 through which the inner string 12 protrudes from the drill tool side through the center support 22 to a rear side.
  • a first rotary drive (not shown) with a first drive shaft 48 is arranged on the base plate 26 and projects through a first inlet opening 35 into the gear housing 20 .
  • a first pinion 49 is formed on the first drive shaft 48 and is in meshing connection with a first externally toothed spur gear 42 of the first gear 40 .
  • a sleeve-shaped first output element 44 is attached to a side of the first spur gear 42 that faces away from the center support 22 .
  • the sleeve-shaped first driven element 44 On its inside, the sleeve-shaped first driven element 44 has internal teeth 45 which engage in external teeth 16 on the inner linkage 12 .
  • the external toothing 16 is axially longer than the internal toothing 45, so that a non-rotatable connection with simultaneous axial displaceability of the internal linkage 12 to the first gear 40 is provided.
  • a displacement device 60 is arranged for the axial displacement of the inner linkage 12 .
  • This has a fastening element 62 which is firmly attached to the outside of the housing attachment 27 .
  • a sleeve-shaped carriage 64 which is connected to the inner linkage 12 in an axially fixed but rotatable manner via a rotary bearing 66 .
  • the carriage 64 and thus the inner linkage 12 can be adjusted relatively axially relative to the fastening element 62 and thus relative to the transmission housing 20 via a lifting cylinder (not shown), with a rod-shaped linear guide 68 being arranged to prevent rotation.
  • the inner linkage 12 can be tubular, with a fluid, in particular a concrete suspension, being able to be fed to the drilling tool side via a basically known rotary feedthrough at the rear end of the inner linkage 12 .
  • the second gear 50 for driving the outer tube is arranged on the opposite side of the central support 22 .
  • a second rotary drive (not shown) with a second drive shaft 58 is arranged on the base plate 26 .
  • the second drive shaft 58 protrudes through a second inlet opening 36 into the gear housing 20.
  • Torque can be transmitted to a second spur gear 52 of the second gear 50 via a second pinion 59 on the second drive shaft 58.
  • a sleeve-shaped second output element 54 is attached to a side of the second spur gear 52 facing away from the center support 22, to which a cardanic connecting element 56 for attaching the outer tube of the double drill rod is attached in a rotationally fixed manner via a transfer ring 55.
  • the inner linkage 12 protrudes through the second output element 54 .
  • the corresponding annular gaps at the housing passages are sealed for oil-tight sealing of the transmission housing 20 via corresponding ring seals.
