description The utility model discloses a whole-section quick drilling type drill carriage for roadway large hollow hole parallel cut blasting. The drill carriage is composed of a walking mechanism, a frame, a hydraulic system, an electric system and two drilling devices, wherein the first drilling device is used for drilling an ordinary blasthole, and the second drilling device is used for drilling a cut hole the diameter of which is at least 100 mm. When the drill carriage works, a main chain wheel of a crawler type traveling chassis is driven by a hydraulic motor to rotate through a speed reducer, the first drilling device and the second drilling device are operated to select hole positions after the carriage body is stabilized, and drilling of the ordinary blasthole and the hollow hole the diameter of which is at least 100 mm can be conducted at the same time after positioning. The drill carriage is suitable for roadways with sectional areas ranging from 8 m to 23 m . Due to the adoption of the modular structure, assembly and assembly are convenient and quick, transportation is convenient, the drill carriage can be used as long as a tunneling roadway is at least 7 m long, mechanization and modernization of tunneling are promoted, and tunneling is made quick and efficient.
