- a basic idea of the invention is to carry out a control of a screwing movement based on a displacement during screwing.
- a theoretical adjustment path is determined as a function of the rotational speed of the drill drive, that is to say in particular the number of revolutions during screwing, and a predetermined thread constant. It can thus be determined which theoretical adjustment path the drill drive has to perform in order to exactly follow the axial feed during screwing.
- This calculated displacement is stored as a target value in a control unit.
- the actual traverse path of the drill drive during screwing is recorded as an actual value via a displacement measuring device.
- a comparison of desired value and actual value takes place, whereby optionally a difference value results.
- an adjustment of the drilling drive and / or the adjusting device can then take place until the actual value approaches or corresponds to the desired value.

- the drilling device it is furthermore possible for the drilling device to also have an overload safety device during screwing, wherein an axial load on the drill drive or the adjusting device is detected. When the limit load is exceeded, the screwing process can be slowed down or preferably terminated.
- the detection of a load thus represents a safety measure, which is not used to control the Verschraubvorganges.
- the inventive method is characterized in that a displacement measuring device is provided, with which an adjustment of the drill drive along the guide during screwing is detected as the actual value that is detected by the control unit, a speed of the drill drive during screwing and taking into account a predetermined thread constants Adjustment path is determined as a target value that is compared by the control unit, the target value with the actual value and a difference value is determined and that the drill drive and / or the adjusting device is adjusted by the control unit according to the determined difference value.
- the inventive method is carried out in particular with the drilling device described above. It can be achieved the advantages described above.
- a preferred method variant of the invention is that a rotational speed, a rotational direction and / or a rotational speed of the drill drive is adjusted until the actual value corresponds to a desired value.
- the drilling drive is controlled and changed in its operation in the regulation of the screwing significantly.
- the adjusting device is moved linearly along the guide until the actual value corresponds to the desired value.
- the control device ie in particular the hydraulic cylinder or a feed winch for the drill drive is influenced by the regulation.
- the method can be carried out with different objectives, such as to achieve the fastest possible screwing of the drill string.
- a particularly efficient drilling operation can be achieved.
- An advantageous variant of the method according to the invention is that the drill drive and the adjusting device are operated so coordinated that on the threaded areas a small load and / or friction occurs. As a result, a particularly thread-conserving operation can be achieved. This saves energy and overall increases the life of the drill string elements.
- the screwing comprises closing and / or releasing a threaded connection between the first threaded region and the second threaded region.
