Abstract

PURPOSE: To save energy consumption for a prime mover, by a method wherein the prime mover is revolved at high speed, when a work of rock-drilling which is accompanied by a severe blows is performed, and except that time, the prime mover is automatically maintained to be revolved at low speed, in an oil hydraulic rock drill provided with an oil hydraulic pump operated by the prime mover.
CONSTITUTION: The oil hydraulic pumps 14W18, operated by the prime mover 19, feed the pressure oil produced, into respective hydraulic actuator. When a machine is running, oil hydraulic motors 32 and 33 for a time of running are operated and controlled by hand-operated valves 21 and 22 for a time of running. The hand- operated valves 23, 24 and 25 are provided to treat a stroke operation, a revolution and a feed for respective rock drill. With such an arrangement, when a hand- operated valve 23 for giving strokes is operated, the pressure oil of an oil hydraulic pump 18 is fed into a servo mechanism 36, as well as a stroke is given by joining the pressure oil of oil hydraulic pumps 14 and 15 through electromagnetic valves 30 and 31, to feed the pressure oil into a stroke unit 34. The motor 19 can be revolved at high speed, by pulling in the rod 38 of a servo mechanism 36 to put a throttle mechanism 35 to a position B.
