Abstract
A drive of a ground drilling device for pushing or pulling introduction of a drill string with a frame and a slide that can be moved back and forth relative to the frame, wherein there is at least one hydraulic cylinder between the frame and the slide for moving the slide, and wherein the hydraulic cylinder can be arranged in a removable manner in two different working directions between the frame and the slide.
Claims10
A drive of a ground drilling device for pushing or pulling insertion of a drill string with a frame and a movable slide movable back and forth relative to the frame, comprising:
- at least one hydraulic cylinder for moving the slide relative to the frame;
- wherein the at least one hydraulic cylinder is arranged in a removable manner in two different working directions between the frame and the slide, wherein the at least one hydraulic cylinder is configured to be rotated in such a way that, after a rotation of the at least one hydraulic cylinder transverse to a longitudinal direction thereof, one side of the at least one hydraulic cylinder is adaptable to be pressurized for both pushing working movement and pulling working movement.
A method for operating a drive of a ground drilling device for driving a drill string into the soil in the pushing or pulling working direction with a frame, a movable slide movable back and forth relative to the frame, and at least one hydraulic cylinder between the frame and slide for moving the slide relative to the frame, comprising:
- removing the at least one hydraulic cylinder from the frame and/or slide,
- and rotating transverse to its longitudinal axis to reverse the working direction.
