Title
(EN) OPERATING SYSTEM, ROCK DRILLING RIG AND METHOD
(FR) SYSTÈME D'EXPLOITATION, APPAREIL DE FORAGE AU ROCHER ET PROCÉDÉ
Abstract
(EN) An operating system, rock drilling rig and method for operating an electrically operated rock drilling rig. The operating system (OS) comprises an electric system (ES) connected to an electric supply source (SS) and comprising one or more electric motors (EM) controlled by means of electric control devices ((1188)). The system further comprises a hydraulic system (HS) comprising one or more hydraulic pumps (HP) and hydraulic control devices (20). There are hydraulic tramming actuators (12) connected to closed loop hydraulic circuits (24, 24a) and hydraulic drilling actuators (19) connected to either open or closed loop circuits (25, 26).
(FR) Un système d'exploitation, un appareil de forage au rocher et un procédé pour faire fonctionner un appareil de forage au rocher électrique. Le système d'exploitation (OS) comprend un système électrique (ES) connecté à une source d'alimentation électrique (SS) et comprenant un ou plusieurs moteurs électriques (EM) commandés au moyen de dispositifs de commande électriques (1188). Le système comprend en outre un système hydraulique (HS) comprenant une ou plusieurs pompes hydrauliques (HP) et des dispositifs de commande hydrauliques (20). Des actionneurs hydrauliques de déplacement (12) reliés à des circuits hydrauliques à boucle fermée (24, 24a) et des actionneurs hydrauliques de forage (19) reliés à des circuits à boucle ouverte ou fermée (25, 26).
