Definitions

  • the invention relates to a rotary drive arrangement for a drill rod with an outer tube and an inner rod running at least partially within the outer tube, in particular for double-head and/or overburden drilling, with a first gear for rotatingly driving the inner rod and a second gear for rotatingly driving the outer tube, wherein the first gear and the second gear are independent of one another, according to the preamble of claim 1.
  • Such a rotary drive arrangement is known, for example, from EP 1 936 109 B1 known.
  • an overall compact structure is achieved by providing a total of three rotary drives above an approximately ring-shaped gear unit for driving the inner rod.
  • An annular gear unit for driving the outer tube is arranged below the gear unit for the inner rod at a distance from it.
  • the spaced gear units are connected to one another via struts.
  • Such rotary drive arrangements are used in drilling rigs to drive a drill rod 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 another ring-shaped drilling tool.
  • the inner rod and the outer tube can be driven in the same or opposite directions with the same or different torque and speed. This allows boreholes to be created efficiently in the ground or rock.
  • the invention is based on the object of specifying a rotary drive arrangement for a drill rod, which enables particularly efficient use with a compact design.
  • the rotary drive arrangement according to the invention is characterized in that the first gear and the second gear are mounted in and surrounded by a common gear housing.
  • the rotary drive assembly must be retracted by a pulling device, usually a winch, when pulling the drill pipe out of a borehole. Reducing the weight of the rotary drive assembly thus also reduces the load during pulling, allowing a greater pulling force to be applied to the drill pipe and thus more efficient drilling operations.
  • a pulling device usually a winch
  • the gear housing has a center support on which the second gear is arranged on a drilling tool side and the first gear on the side facing away from the drilling tool side, wherein the center support, which runs approximately perpendicular to the drilling axis, 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 gears can be arranged further functionally separated from one another, wherein the arrangement of the gears on both sides of the A good distribution of forces is achieved through the center support, which leads to a particularly stable housing construction.
  • the center support has a passage for the inner rod.
  • the inner rod can thus extend further back through the center support from the drilling tool side.
  • the two gear chambers can be in fluid communication via the passage, for example for a common gear oil filling.
  • the gear housing can be sealed from the inner rod by a simple sealing device.
  • the gear housing can be sealed on the one hand on the drilling tool side by a sealing device from the inner rod and on the other hand by a further sealing device from the outer rod or the output unit for the outer rod.
  • the first gear for driving the inner rod is arranged in the first gear chamber and the second gear for driving the outer tube is arranged in the second gear chamber.
  • 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 rod.
  • the inner rod 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 located 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 gear housing.
  • the inlet 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 for driving the inner rod, which is connected to the inner rod in a rotationally fixed but axially displaceable manner.
  • external teeth are thus formed with a certain axial extension, which is longer than a width of the spur gear, whereby an axial displacement of the first spur gear relative to this is made possible. This allows the inner rod to be axially displaced relative to the first gear, while at the same time torque transmission is still possible.
  • 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 connection element to which an outer tube, in particular a drill pipe, can be detachably attached.
  • a particularly compact design is achieved according to a further development of the invention by arranging the gear housing on a base plate on which in 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 that a displacement device is arranged on an outer side of the gear housing, which is axially fixed but rotatably connected to the inner rod for axially displacing the inner rod relative to the gear 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 gear housing and is firmly connected to it.
  • the displacement device is preferably connected to the rotationally driven inner rod via a rotary bearing, so that the inner rod can continue to rotate 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, as described above.
  • the drilling drive carriage is slidably mounted by means of a cable pull system or actuating cylinders along a vertical mast or a carriage that can be adjusted in space about several axes.
