Abstract

The invention discloses a power head cruising drilling method and system and a rotary drilling rig. The method comprises the following steps of starting, collecting a set of operation signals when an operation device of a power head controls the power head, stopping collecting the operation signals, storing the collected operation signals to be control data, controlling power head drilling according to the control data, detecting whether the operation stopping power head cruising drilling exists, if yes, stopping controlling power head drilling according to the control data, and if no, the last step is executed. The power head cruising drilling method can simulate the operation of operators to control power head drilling, and therefore in the power head drilling process, the operation time of the operators is shortened, the labor intensity of the operators is lowered, and the fatigue due to long-time repeated operation is relieved.

Description

Technical field [0001] The invention relates to the field of engineering machinery, in particular to a power head cruise drilling method, a power head cruise drilling system and a rotary drilling rig provided with a power head cruise drilling 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 cyclical process. During the drilling process, the operator needs to maintain or repeat a drilling handle action for a long time. On the one hand, during the drilling process of the rock formation, due to the slow drilling of the rock formation, it is often necessary to repeat the handle operation for an hour or more, and the operation of the handle is often also periodic. On the other hand, depending on the geology of the rock formations and the operating habits of the operators, the power head speed and pressurizing frequency are different. However, during a certain period of...
