  • Drilling device and method for screwing drill rod elements to a drilling device
    Patent number: 10619430
    Abstract: A drilling device having a drill drive, a positioning means, a receiving part, a clamping means, and a control unit. The receiving part holds a first drill rod element with a first thread region. The clamping means is positioned on the drill drive for holding at least a second drill rod element having a second thread region. The control unit actuates the drill drive and the positioning means to screw the first and second thread regions together. A distance measuring means detects an adjustment distance of the drill drive along a guide as an actual value. The control unit determines an adjustment distance as a nominal value from a detected revolution speed of the drill drive during screwing and a predetermined thread constant. The control unit determines a difference from the nominal and actual values, and uses the difference to adjust the drill drive and/or the positioning means.
