Abstract
Arrangement of a ground drilling device for the pushing or pulling introduction of a drill string into the ground, wherein the arrangement has a frame and a carriage which can be moved back and forth relative to the frame with a translatory movement, wherein at least one rolling element is provided, which is configured to roll during the translatory movement of the carriage, and a conversion device is provided, which is connected to the rolling element and is configured to convert the rotary movement of the rolling element into a rotary movement of the drill string.
Claims12
A ground drilling device (1) comprising a frame (8) and a carriage (4) which can be moved back and forth relative to the frame (8) with a translatory movement, wherein at least one rolling element (15) is provided, the at least one rolling element configured to roll, with rotary movement, during the translatory movement of the carriage (4), wherein the rotary movement of the rolling element (15) is converted into a rotary movement of a drill string (5),
- wherein the ground drilling device introduces the drill string (5) into the ground by a pushing or pulling movement.
(canceled)
A method of operating a ground drilling device (1), comprising
- moving a carriage (4) of the ground drilling device (1) back and forth relative to a frame (8) with a translatory movement in order to drive a drill string (5) in a pushing or pulling working direction into the ground, wherein a rolling element (15) rolls, with rotary movement, during the translatory movement and the rotary movement of the rolling element (15) is converted into a rotary movement of the drill string (5).
A method of using a ground drilling device (1) for the pushing or pulling introduction of a drill string (5) into the ground, wherein the arrangement has a frame (8) and a carriage (4) which can be moved back and forth relative to the frame (8) with a translatory movement, wherein at least one rolling element (15) is used, wherein the at least one rolling element rolls during the translatory movement, and the rolling movement is used to impart a rotary movement to the drill string (5) by means of the rotary movement of the rolling element (15).
