摘要： A first gearbox (10) is connected to a first drive unit (11) to turn the inner rod. A second gearbox (20) is longitudinally offset from the first, along the longitudinal direction of the drilling rod. This (20) is connected to at least one second drive unit (21), to turn the outer tube. In novel design, the second drive unit is spaced away from the second gear box (20) and the second drive unit is arranged near the first drive unit on the first gear box. An independent claim IS INCLUDED FOR the corresponding drilling method.

摘要： The invention provides a drive device for driving a drill rod, which has an outer rod and an inner rod. The device comprises a first rotary drive unit, with which the outer rod can be driven in a rotating manner via an outer drive shaft, and a second rotary drive unit, with which the inner rod can be driven in a rotating manner independently of the outer rod via an inner drive shaft. A vibration unit for generating a vibration is also included which has a vibration element that can be driven in a vibrating manner. For transmission of the vibration to the outer drive shaft, the vibration element is connected via a first transmission unit to the outer drive shaft and for transmission of the vibration to the inner drive shaft the vibration element is connected via a second transmission unit to the inner drive shaft.
