ROCK-DRILLING UNIT AND METHOD OF ITS MOVING Russian patent published in 2015 - IPC E21B7/02 

FIELD: mining.

SUBSTANCE: group of inventions relates to the field of drilling, namely to blast-hole drilling in mines. The rock-drilling unit has an electric drive and comprises a bogie fitted with wheels for its movement; drilling boom designed with a possibility of movement using the manipulator actuating device with reference to the bogie; the drilling unit comprising the travel beam, rock-drilling unit, which comprises the percussion mechanism, axis arrangement and haulage for movement of the rock-drilling unit on the travel beam; a hydraulic system for drilling fitted with a hydraulic pump, the energy of pressure of which actuates one of drilling actuators; driving equipment comprising the driving electric motor and mechanical transmission device for transmitting of the driving force from the driving electric motor to wheels. The drilling hydraulic system pump and mechanical gearbox are designed with a possibility of being driven by the common electric motor. The drilling hydraulic system and mechanical gearbox are designed with a possibility of independent from each other connecting and disconnecting for enabling and disabling by the electric motor through clutches.

EFFECT: simplification of accommodation of the transmission system components in the travel mechanism is ensured.
