ROCK DRILLING RIG AND METHOD FOR TRANSMISSION OF ROCK DRILLING RIG
First Claim
1. A rock drilling rig which is electrically driven comprising:
- a carriage having a plurality of wheels for moving the carriage;
at least one drilling boom movable by at least one boom actuator in relation to the carriage;
at least one drilling unit including a feed beam, a rock drilling machine supported by the feed beam, the rock drilling machine including at least a percussion device and a rotating device, and a feeding device for moving the rock drilling machine on the feed beam;
a hydraulic drilling system including at least one hydraulic pump having a pressure energy that drives at least one of the following drilling actuators;
the percussion device, the rotating device, the feeding device, and the boom actuator; and
a drive equipment including at least one electric drive motor and mechanical drive transmission means for transmitting driving power from the drive motor to the wheels, wherein the hydraulic pump of the hydraulic drilling system and the mechanical drive transmission of the drive equipment are driven by at least one common electric motor, andare each independently connectable and disconnectable by a klutch to be driven and not to be driven by the electric motor.

Abstract
A rock drilling rig and to a method for transmission thereof is provided. The rock drilling rig includes a carriage that is movable by drive equipment in a mine. The rock drilling rig includes a hydraulic drilling system for which pressure energy is generated by a hydraulic pump. The rock drilling rig is electrically driven and includes an electric motor that is connected to drive both the drive equipment and the hydraulic drilling system. The mechanical drive transmission included in the drive equipment and the hydraulic pump of the hydraulic drilling system may be connected and disconnected independently of one another by means of clutches.

6. A method for transmission in an electric rock drilling rig, the method comprising the steps of:
-
moving a carriage of the rock drilling rig by drive equipment that includes at least one electric drive motor; transmitting the driving power generated by the drive motor by mechanical drive transmission means to the wheels of the carriage; drilling boreholes in a rock using drilling actuators in the drilling; driving at least one hydraulic pump by at least one electric motor and providing pressure energy for the hydraulic drilling system; driving with the pressure energy of the hydraulic drilling system at least one of the following drilling actuators;
a percussion device, a rotating device, a feeding device, a boom actuator;transmitting the driving force from a common electric motor to the hydraulic pump of the hydraulic drilling system and to the mechanical drive transmission of the drive equipment; and controlling independently, by means of clutches, the connection and disconnection of the hydraulic drilling system and the mechanical drive transmission driven by the common electric motor. - View Dependent Claims (7, 8)
