The invention discloses a power head cruising drilling method, a power head cruising drilling system and a rotary drilling machine. The method comprises the following steps of starting the machine; collecting a group of operation signals which are transmitted by an operating device and used for controlling a power head; stopping collecting the operation signals of the operating device, and converting the collected operation signals to control data of a digital signal format to be stored; converting the format of the control data to an electrical signal format, transmitting the electrical signal to an electrical hydraulic control valve, and controlling the openness of a multi-way valve through the electrical hydraulic control valve so as to realize the cruising drilling of the power head; detecting whether a signal for stopping the cruising drilling of the power head exists or not, stopping controlling the cruising drilling of the power head if the signal exists, and otherwise, returning to the previous step. By adopting the power head cruising drilling method, the automatic cruising drilling of the power head is controlled by controlling a multi-way valve, so that the operation time of the operator can be reduced, the labor intensity of the operator can be alleviated, and the fatigue caused by the repeat operation for a long time can be alleviated.
Description
technical field [0001] The invention relates to the field of mining drilling machinery, in particular to an automatic control method and system for a rotary drilling rig, and a rotary drilling rig equipped with the system. Background technique [0002] When the rotary drilling rig is working, the drilling of the power head and the pressurization of the pressurizing device are a reciprocating process. During the drilling process, the operator needs to maintain or repeat a drilling handle action for a long time. On the one hand, in the rock formation drilling process, due to the slow drilling of the rock formation, it is often necessary to repeat the handle operation for one hour or more, and the operation of this handle is often also periodic. On the other hand, according to the different geology of the rock formation and the different operating habits of the operator, the power head speed and pressurization frequency are different, but during a certain period of drilling, t...
