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.
Claims10
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) mounted on the carriage (4) and a counter-element (14) arranged in a stationary manner outside of the carriage (4) are provided,
- the at least one rolling element configured to roll, with rotary movement when moved translationally together with the carriage (4) and in engagement with the counter-element (14), so that the translational movement of the carriage (4) is converted into the rotary movement of the rolling element (15)
- wherein the ground drilling device introduces the drill string (5) into the ground by a pushing or pulling movement, and
- further comprising a conversion device (24) that is connected to the rolling element (15) and configured to convert the rotary movement of the rolling element (15) into a rotary movement of the drill string (5).
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) is mounted on the carriage (4) and a counter-element (14) is arranged in a stationary manner outside of the carriage (4),
- wherein the rolling element (15) rolls, with rotary movement, when moved translationally together with the carriage (4) and in engagement with the counter-element (14), so that the translational movement of the carriage (4) is converted into the rotary movement of the rolling element (15)
- wherein the ground drilling device (1) further comprises a conversion device (24) that is connected to the rolling element (15) and configured to convert the rotary movement of the rolling element (15) 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 mounted on the carriage (4) and a counter-element (14) is arranged in a stationary manner outside of the carriage (4),
- wherein the at least one rolling element rolls, with rotary movement, when moved translationally together with the carriage (4) and in engagement with the counter-element (14), so that the translational movement of the carriage (4) is converted into the rotary movement of the rolling element (15)
- wherein the ground drilling device (1) further comprises a conversion device (24) that is connected to the rolling element (15) and configured to convert the rotary movement of the rolling element (15) into a rotary movement of the drill string (5).
