Definitions

  • the invention is directed to a drilling device comprising a guide frame, a guide table which is mounted on the guide frame so as to be movable in a longitudinal direction of the guide frame, and a drill drive which is fastened on the guide table and which has a motor-driven clamping head for rotating a drill rod and a rod. Implementation which enables a drill rod released by the clamping head to be pulled through the drill drive.
  • a drilling device for horizontal drilling comprising a drill head, a drill rod and a drive device which is designed for the rotary drive and feed drive of the drill rod.
  • the drill rod has an inner rod and an outer rod, between which an annular space for guiding a flushing fluid from a rotary connection to the drill head is formed.
  • the inner linkage comprises a straightening space which extends from the drive device to a terminating element on the drill head side. At least part of a targeting device for controlling the direction of the drill head is arranged in the straightening space.
  • a rod positioning device which is attached to a frame and moves a drill rod from a magazine into the drilling axis in order to then connect the drill rod to a drill rod already arranged in the drilling axis.
  • a Kelly bar drilling device which is driven to rotate by a drill head, the drilling device having at least one outer Kelly bar which is arranged only below the drill head and which is either one on the drill head provided rotating transition piece or is driven by the next inner Kelly bar. At least the outermost Kelly bar does not run through the drill head, so that the diameter of the drill head can be kept small and yet a great drilling depth can be achieved.
  • a drilling device for creating a borehole in a ground is known, a drill rod being driven to rotate via a drive shaft of a rotary drive and being introduced into the ground in order to create the borehole.
