Definitions

  • the invention relates to a drilling device for earth or rock drilling with a mast, a drilling drive with a drilling drive shaft for rotatingly driving a drill pipe, a drilling drive carriage which is movably mounted along the mast and on which the drilling drive is arranged, and a vibratory drive which is used for generating a vibration formed in a drilling direction behind the drill drive and is connected to the drill string for transmitting a vibration, a rear connecting end of the drill drive shaft of the drill drive or drill string protruding rearward from the drill drive, according to the preamble of claim 1.
  • the invention further relates to a method for retrofitting a drilling device for earth or rock drilling with a mast, a drilling drive with a drilling drive shaft for rotatingly driving a drill pipe and a drilling drive carriage which is movably mounted along the mast and on which the drilling drive is arranged, according to the preamble of claim 9.
  • Such drilling devices for earth or rock drilling with a drill drive and a vibration drive have long been known for performing a so-called vibration drilling or percussion drilling.
  • a generic drilling device goes from the JP-H05 311967 A. forth.
  • the DE 100 06 973 C2 discloses a vibratory displacement screw for the manufacture of bored piles.
  • a drill pipe is driven by a rotary drive on the mast of the drill attached, screwed into the bottom of the drill.
  • the drill pipe has a vibration generator with a rotating eccentric weight.
  • the vibration generator is integrated in the drill pipe, and no vibrating movement is generated in the axial direction.
  • the DE 697 20 480 T2 describes a coupling piece for rotary impact drilling for a rotary impact drill.
  • a rotary impact device is attached to a drill pipe via a connection, which is not described in detail and which comprises a keyway connection.
  • a vibration drive is located in a front area of the downhole drill, while a rotary drive is located in a rear area.
  • a connection is provided via a universal joint.
  • a vibration exciter for a drilling device is further out of the EP 2 781 269 A1 known.
  • the invention is based on the object of specifying a drilling device which, with a simple structure, can also carry out drilling in combination with vibration generation. Furthermore, it is an object of the invention to provide a method for retrofitting such a drilling device.
  • the drilling device is characterized in that at the connection end a rotary coupling with a first coupling piece which is axially fixed and is non-rotatably connected to the connecting end, and a second coupling piece is provided, which is axially fixed and rotatable relative to the first coupling piece, and in that the vibration drive has a tensioning device which is designed for releasably tensioning the second coupling piece, an axially in the tensioned state fixed connection between the vibration drive and the second coupling piece is formed.
  • a basic idea of the invention can be seen in providing a separate vibratory drive in a drilling device for drilling earth or rock, which can be detachably coupled to the drilling drive.
  • vibration drive and vibration are to be understood in general, whereby in principle these can include not only vibrating and shaking, but also hitting or other vibrations.
  • the vibratory drive can be connected to the drilling drive as required.
  • the drill drive is designed in a special way in such a way that a connecting end of the drill drive shaft of the drill drive or of the drill rod itself protrudes rearward from the housing of the drill drive.
  • a first coupling piece of a rotary coupling is attached to the connection end in an axially fixed and rotationally fixed manner.
  • the rotary coupling further comprises a second coupling piece, which is arranged axially fixed and rotatable relative to the first coupling piece on the latter.
  • the second coupling piece is designed in such a way that it can be detected by means of a tensioning device on the vibration drive, so that a connection which transmits the vibration of the vibration drive to the drilling drive shaft is created via the rotary coupling.
  • the entire drill drive can also be set in motion.
  • the drill drive can also be designed in the form of a ring, the drill rod projecting rearward from the drill drive.
  • the rotary coupling described can be provided at the rear connecting end of the drill pipe.
  • the tensioning device can be released and the vibration drive can be decoupled from the drilling drive. This basically reduces the internal friction of the entire drive arrangement in drilling operation.
  • the vibration drive can also be provided and offered as an option for normal drilling devices. Retrofitting existing drilling devices is also possible in principle.
  • the tensioning device can be designed in any way in order to create a suitable vibration-transmitting connection between the vibration drive and the drill drive shaft.
  • the clamping device in particular a collet with radially adjustable clamping claws, has a non-positive and positive connection.
  • the tensioning devices can generally be used to create a non-positive and / or positive connection to the second coupling piece of the rotary coupling. Clamping takes place via an active clamping actuation.
  • a further advantageous embodiment of the invention consists in that the vibration drive is mounted on a vibration drive slide which can be moved relative to the drill drive slide.
  • the vibration drive carriage is preferably arranged to be displaceable along a mast.
  • a separate displacement drive can be provided for displacement, which can comprise an actuating cylinder or a cable winch.
  • the vibration drive carriage with the vibration drive can be separated and removed from the drilling drive.
  • the vibration drive carriage with the vibration drive can be removed from the immediate working area of the drilling drive. This protects the vibration drive.
  • the vibration drive can be designed in any known manner in order to generate targeted vibrations which can be transmitted to a rotating drilling tool. In particular, this can also be a striking generation of vibrations. According to one embodiment of the invention, it is particularly preferred that the vibration drive is designed as a vibrator.
  • the vibrator has at least one pair of rotationally driven unbalance units.
  • a plurality of rotationally driven unbalance units can be arranged, which are mutually adjustable. This allows an almost infinitely variable setting and a targeted alignment of the vibrations, in particular in the drilling direction.
  • the vibrator can also be designed with an oscillating axial piston for generating vibrations.
  • the mast is arranged essentially vertically.
  • the mast can be a rigid mast with a linear guide or a so-called leader.
  • the mast can, in particular, be pivoted to a certain extent about a vertical axis or tilted to it.
  • vibration drive is mounted on the vibration drive slide in a vibration-damping manner.
  • an extensive decoupling of the vibration drive from a basic slide can be achieved, for example in that rubber bearings are arranged in between. In this way, excessive transmission of vibrations from the vibration drive to the mast and the drilling device as a whole can be avoided.
  • the method according to the invention for retrofitting a drilling device for earth or rock drilling is characterized in that at a rear connecting end of the drilling drive shaft of the drilling drive or of the drill pipe, a rotary coupling with a first coupling piece, which is axially fixed and non-rotatably connected to the connecting end, and a second coupling piece is provided, which is axially fixed and rotatable relative to the first coupling piece, and that an oscillation drive with a tensioning device is arranged behind the drill drive which is designed for releasable tensioning of the second coupling piece, an axially fixed connection being formed between the vibration drive and the second coupling piece in the tensioned state.
  • the vibratory drive can be arranged on a vibratory drive carriage, which can be moved along a guide on the mast, on which the drill drive is also moved with a drill drive carriage.
  • an existing drilling device can be efficiently provided with an additional vibration or oscillation device as required.
  • the drilling device described above can be produced with the method according to the invention.
  • the advantages described above can be achieved.
  • a drilling device 10 according to the invention is shown schematically in a side view in the drawing.
  • the drilling device 10 has a drilling drive 20 and a vibration drive 30, which is arranged in the drilling direction behind the drilling drive 20.
  • the drill drive 20 is mounted on a drill drive carriage 24 and is displaceably mounted along a linear guide, not shown, on a mast 12, which is only shown in abbreviated form.
  • the vibration drive 30 is mounted on the mast 12 via a vibration drive slide 34 along the linear guide.
  • the mast 12 is preferably arranged on a carrier vehicle, not shown.
  • the drill drive 20 has a drill drive shaft 22 which can be connected at its front end to a drill pipe (not shown).
  • the drill drive 20, which in particular comprises a hydraulic motor, generates a torque which is transmitted to the drill string via the drill drive shaft 22.
  • the drill drive shaft 22 is axially displaceably mounted in a housing of the drill drive 20, with a rear connecting end 26 protruding toward the rear.
  • the rear Connection end 26 is connected to the drill drive shaft 22 and in particular represents the rear end of the drill drive shaft 22.
  • a rotary coupling 40 is attached to the rear connection end 26 and has a first coupling piece and a second coupling piece (not shown in more detail).
  • the first coupling piece of the rotary coupling 40 is axially fixed and non-rotatably connected to the rear connecting end 26 of the drill drive shaft 22.
  • the second coupling piece of the rotary coupling 40 is axially fixed to the first coupling piece and is rotatable relative to the first coupling piece.
  • the vibration drive 30, which in particular has a vibrator with a plurality of rotatingly driven unbalance elements, comprises a front clamping device 32 directed towards the drilling drive 20.
  • the clamping device 32 is in particular a collet with radially adjustable clamping claws 36.
  • the second coupling piece can be used with the clamping claws 36 of the clamping device 32 non-positively and / or positively captured.
  • a vibration or oscillation movement which is directed in the drilling direction and which is generated by the vibration drive 30 can be transmitted to the second coupling piece and from this to the first coupling piece of the rotary coupling 40.
  • This vibration or oscillation movement is transmitted from the first coupling piece to the rear connecting end 26 of the drill drive shaft 22 due to the axially fixed connection of the first coupling piece.
  • a rotary movement of the drill drive shaft 22 generated by the drill drive 20 can be combined or superimposed with an axially directed vibration or oscillation movement, as indicated by the arrows shown.
  • Damping elements (not shown), which are arranged between the housing of the vibration drive 30 and the vibration drive slide 34, can be used to prevent or at least largely reduce the direct transmission of vibrations from the vibration drive 30 to the mast 12.
  • a corresponding damping can also be arranged between the housing of the drill drive 20 and the drill drive carriage 24.
  • the clamping device 32 can be released.
  • the clamping claws 36 are moved radially outward, the connection to the rotary coupling 40 is solved.
  • the vibration drive 30 can now be moved backwards along the mast 12 via an adjustment drive (not shown) and can thus be spaced apart from the drilling drive 20.
  • the two drives can then be combined again by the drilling drive 20 and the vibration drive 30 moving together. The unit formed in this way from the drill drive 20 and the vibration drive 30 can then be moved uniformly along the mast 12.
  • the detachable arrangement of the vibration drive 30 allows according to the invention that even existing drilling devices 10 can be provided with a vibration drive (30) subsequently.
