Abstract

Electric drill that consists of drill bit, body, electric motor with hollow shaft and current lead connected with its upper end to source of power supply at the surface of the drill hole, and with the lower end to electric motor of electric drill. In electric drill not less than two drill bits (the inner and the outer ones) are used. Electric motor has rotor, stator, current lead, brushes connected to contact rings. Stator is fixed in bearings and has possibility of rotation with respect to the rotor. Rotor with hollow shaft is connected to the inner drill bit and the stator rotating with respect to the rotor in opposite direction is connected to the outer drill bit. Pump for pumping washing liquid with local circulation is rigidly connected to electric motor at axis. Current lead is connected to power source by means of non-split cable-rope and has unit for current collecting, transfer of mechanical force to electric drill at axis, and compensation of torque to cable-rope.
