Abstract

The invention discloses a drilling device for dangerous rock monomer blasting, which belongs to the technical field of geological disaster prevention and control engineering devices and comprises a single cantilever mechanism, a vertical connecting mechanism, a transverse moving mechanism, a drilling position adjusting mechanism and a drilling mechanism. The two ends of a top beam of the single cantilever beam mechanism are supported between the dangerous rock single body and the stable mountain body, and an aerial operation platform is constructed; a cross beam of the transverse moving mechanism is suspended below the top beam through a vertical connecting mechanism; the drilling position adjusting mechanism achieves two-dimensional accurate positioning in the transverse direction and the vertical direction through a transverse moving trolley, a vertical rail base and a vertical moving trolley. A drilling rail of the drilling mechanism can rotate around a horizontal shaft to drive a drill bit to adjust the pitching angle. According to the method, dependence on the dangerous ground is eliminated, suspended, multi-angle and high-precision drilling operation under the complex terrain is achieved, the problems that a traditional method is difficult in platform building, low in positioning precision, poor in safety and the like are effectively solved, and the efficiency, safety and adaptability of dangerous rock blasting construction are remarkably improved.
