  • DE 196 08 980 C2 describes a Erdbohrvorraum, which consists of a carriage with a hydraulic piston-cylinder unit, which linearly moves a carriage back and forth. The carriage is connected to a pawl which, when the carriage is advanced, engages behind a rung of a ladder rod which is part of a drill string and thus advances the ladder rod with the drill head in accordance with the stroke of the hydraulic piston-cylinder unit in the drilling direction. At the end of the stroke, the pawl automatically disengages from the rung and the carriage returns to its original position.

  • the invention also provides a method for operating an earth drilling device, in which a carriage of the earth drilling device is moved back and forth relative to a frame with a translatory movement to drive a drill string in the pushing or pulling working direction into the ground, with a rolling element being used in the translatory movement rolls and the rotational movement of the rolling element is converted into a rotational movement of the drill string.
  • the invention also provides a use of an arrangement of an earth drilling device for pushing or pulling insertion of a drill string into the ground, the arrangement having a frame and a carriage which can be moved back and forth relative to the frame with a translatory movement, with at least one rolling element being used which rolls during the translational movement and the rolling movement is used to impart a rotary movement to the drill string by means of the rotational movement of the rolling element.
  • Numerical information within the meaning of the description is information that may have a tolerance of +/- 10%, in particular +/- 5%, so that the numerical information not only describes one value, but a range of values, in particular tolerance ranges that may be production-related, to be taken into account.
  • the invention has been described in relation to three aspects relating to the arrangement, the method and the use.
  • the description of the individual aspects with features which also includes the design of the earth drilling device with the arrangement, complement each other in terms of their description, so that in particular statements on the aspect of the arrangement, i.e. in particular features of a device, also for the description of the other aspects by means of features of a process or use apply. If a feature is described with regard to one aspect, in particular the arrangement, then this description is also to be understood as a description for a feature of the method or use and also of the earth drilling device.
  • the earth drilling device 1 shows a plan view of an arrangement of an earth drilling device 1.
  • the earth drilling device 1 For anchoring or stabilizing the earth drilling device 1 in a starting pit or a sewer shaft, the earth drilling device 1 has extendable or extendable support elements 2, which are arranged in the corner areas of a frame 8 of the earth drilling device 1.
  • a drill string 5 having rod sections can be introduced into the ground by means of the earth drilling device 1 .
  • the drill string 5 has an earth drilling tool in the form of a drill head 6 arranged at the front.
  • a transmitter mount 7 is arranged in the drill string 5 behind the drill head 6 .
  • two hydraulic cylinders 3 are provided, which move an engaging element 10 designed as a pawl, which can be connected to the drill string 5, back and forth.
  • the engaging element 10 is fixed to a carriage 4 .
  • the engagement element 10 is attached to the carriage 4 in such a way that a change in the working direction is possible.
  • the engagement element 10 can be rotated.
  • the carriage 4 can move relative to the frame 8 by means of an operation of the hydraulic cylinders 3. This allows a translational movement of the carriage 4 relative to the frame 8 in a reciprocating movement.
  • a fixed point for a detachable attachment of the hydraulic cylinder 3 is provided on a front frame plate 9 and on a rear frame plate 11 .
  • the engagement element 10 pushes itself out of a groove 12 of a rod section of the drill string 5 during retraction (idle stroke) and falls into a further groove 12 of a rod section when it reaches it these into it, so that the hydraulic cylinders 3 can further advance the drill string 5 in a working stroke.
  • pulling working direction of the hydraulic cylinders 3, such as may be required for pulling in lines the hydraulic cylinders 3 are rotated transversely to their longitudinal direction. It is possible that the cylinder or piston side of the hydraulic cylinder 3 with the greater force is available for the working stroke and the piston rod side can be used for a quick return stroke, ie the idle stroke.
  • the arrangement of the Erdbohrvoriques 1 has a rolling element 15, which in the embodiment of 1 is designed as a sprocket.
  • the rolling element 15 is mounted on the carriage 4 with a shaft which is non-rotatably connected to the rolling element 15 and rolls off during the translatory movement of the carriage 4 .
  • the rolling takes place on a counter element 14 designed as a roller chain.
  • the rolling element 15 engages in the counter element 14 . With the movement of the carriage 4 back and forth, the rolling element 15 is rotated.
  • a conversion device 24 which has a toothed belt pulley 16 (drive element) which is connected in a torque-proof manner to the rolling element 15 and which drives a toothed belt 17 .
  • the toothed belt 17 is rotated by means of a deflection roller 18 on the one hand in its longitudinal direction by 90 degrees and on the other hand angled by 90 degrees, where it drives another toothed belt pulley 19 (driven element).
  • the toothed belt pulley 19 is non-rotatably connected to a receptacle 20 for the drill string 5 .
  • the receptacle 20, which is coupled to the toothed belt pulley 19, rotates the drill string 5 when it is acted upon by the conversion device 24.
  • a translational movement of the carriage 4 triggered by the hydraulic cylinder 3 can be converted into a rotary movement of the drill string 5.
  • the drill string 5 with the drill head 6 at its front end can be rotated during the pushing or pulling insertion.
  • directional drilling can be achieved in such a way that the drill head 6 is brought into a specific radial position (clock time) associated with the desired change in direction. This can arise, for example, by the fact that the carriage 4 is brought into a position in which the drill head assumes the desired radial position with regard to its time.
  • a clutch can separate the non-rotatable connection between the driven toothed belt pulley 19 (driven element) and the receptacle 20 (engagement element for the rotary movement).
  • the engagement of the rolling element 15 with the counter-element 14 can be separated, for example by the rolling element 15 being moved or pivoted out of engagement with the counter-element 14 . It can also be provided that the engagement of the rolling element 15 with the counter element 14 can be achieved by lowering or raising or pivoting the counter element 14 away. After the end of the change in direction of the drilling process, the original state can be restored, so that the drill string 5 with the drill head 6 rotates again during the linear movement of the carriage 4 .
  • FIG. 3 shows an alternative embodiment of an arrangement of an earth drilling device 1 with the earth drilling device 1 and a drill string 5 in plan view.
  • the same elements are provided with the same reference numbers and essentially the toothed belt drive of the conversion device 24 has been switched off 1 replaced by a bevel gear drive.
  • the counter-element 14 is designed as a roller chain and, during the linear movement of the carriage 4, causes the rolling element 15, which is designed as a chain wheel, to rotate.
  • the rolling element 15 designed as a chain wheel is connected via a shaft 21 in a rotationally fixed manner to a bevel gear 22 designed as a pinion of a conversion device 24 designed as a bevel gear and drives the bevel gear 23 of the conversion device 24, which in turn is connected in a rotationally fixed manner to the receptacle 20 for the drill string 5, and thus the drill string 5 with the drill head 6.
  • the rotational movement is interrupted in a manner analogous to that for the embodiment in FIGS Figures 1 and 2 is described, by means of a clutch on the conversion device 24 or alternatively by physical separation of the rolling element 15 and the counter-element 14.
