  • Drilling machine provided with an electrically-braked moving device for the drilling string
    Patent number: 11773652
    Abstract: Drilling machine (1) comprising: a supporting structure (3); a drilling string (12); a drilling head (11); a flexible tensile element (17); a moving device (21), mechanically connected to the supporting structure (3) and mechanically associated with the flexible tensile element (17) to hold and move the drilling string (12); at least one first electric motor (22) configured to, in a first operating mode, actuate the moving device (21) so as to lift the drilling string (12), and configured to, in a second operating mode, apply a braking mechanical power on the moving device (21) so as to brake in a controlled manner the lowering of the drilling string (12) to reach and maintain a desired controlled lowering speed (Vd), the at least one first electric motor (22) being also configured to produce an electric power (Pmot); a first bidirectional electric power converter device (23) configured to convert the electric power produced (Pmot) into converted electric power (Pregen); an electric energy transmission networ
