AI Technical Summary
Technical Problem
Existing crawler tunnel drilling rigs are easily interfered with by components during rotary drilling, the mast rotation angle is limited, and the motor travel is restricted by the cable length, resulting in low maneuverability and high cost.
Method used
A composite swing mechanism is used to achieve 180° vertical flipping of the mast and horizontal height adjustment. Combined with a traveling fuel tank and a traveling diesel engine, the electric motor drive is eliminated, thereby enhancing maneuverability and flexibility.
Benefits of technology
Effectively avoid interference from surrounding components, improve drilling flexibility and operating range, reduce safety risks, reduce usage costs, and increase activity space.

Abstract
The utility model relates to the technical field of mining machinery, in particular to a crawler-type full-hydraulic underground drill rig which comprises a machine base and a crawler belt assembly arranged below the machine base, a supporting part not higher than the crawler belt assembly is arranged in the middle of the machine base in a sinking mode, a rotary seat is installed on the supporting part through a rotary disc, and a mast carrying a drilling assembly is arranged above the rotary seat. A composite swing mechanism for driving the mast to vertically turn over by 180 degrees is arranged between the rotary seat and the mast; the mast is vertically overturned by 180 degrees for drilling through the composite swing mechanism, the height of the overturning axis of the mast is adjusted through the first oil cylinder, the posture of the mast is leveled through the second oil cylinder, and therefore the height of the mast in the horizontal rotation process is increased, and the mast effectively avoids interference of surrounding components in the rotation drilling process. A walking system composed of a walking oil tank and a walking diesel engine is adopted, the limitation of the length of a cable is eliminated, the safety risk in operation is reduced, and the trafficability and maneuverability of the drilling machine in complex terrains are improved.
