The invention discloses an automatic tunnel drilling
machine and method. The drilling
machine comprises a track vehicle
chassis, a control supporting box, a
hydraulic control box, a central supportingshaft, a transverse shaft, an electric
drill, a positioning detection mechanism and an electric
drill fine-adjusting device, wherein a
drill bit of the electric drill is provided with a limiting sensor and a speed sensor. The method comprises the steps that 1, hole position marks are arranged; 2, the drilling
machine executes automatic drilling in a tunnel section; 3, the drilling machine executes automatic tunnel drilling; 4,
troubleshooting is executed. Movement of the drilling machine in the length direction of a tunnel is achieved through the track vehicle
chassis, coarse alignment for drilling is achieved, the
bearing capacity is large, fine alignment for drilling is achieved through a planar movement mechanism, control is simple, microcosmic fine alignment for drilling is achieved through the cooperation of a dip angle adjusting oil
hydraulic cylinder and a main oil cylinder, effort is saved, operation is accurate, labor is saved, the
safety risk and construction difficulty arereduced, a large amount of dust is prevented from being inhaled during manual operation, and the harm to body health of constructors and unnecessary personal injuries are decreased.
