| titleOfInvention | A drilling mechanism and a lifting drilling rig |
| abstract | The utility model relates to the technical field of tunnel excavation and stone underground mining equipment, in particular to a drilling mechanism and a lifting drilling rig. The drilling mechanism comprises a drilling device, a connecting shaft, an arm rod and a power source; the arm rod It is a telescopic rod, including a telescopic outer tube and a telescopic inner tube that is telescopic in the telescopic outer tube; the power source is fixed in the telescopic inner tube, and the output end of the power source extends outward from the telescopic inner tube and is connected to the connecting shaft. The other end of the connecting shaft is connected with the drilling device; the elevating drilling rig includes a frame and several drilling mechanisms, and the telescopic outer tubes in the drilling mechanism are respectively connected with the frame for fixing the drilling mechanism on the frame The frame includes a fixed frame and a lift frame that slides up and down in the fixed frame, and the lift frame moves up and down to drive the drilling mechanism fixed on the lift frame to rise and fall. The drilling mechanism and the lift-type drilling rig can effectively solve the problems of insufficient propulsion of the drilling rig and easy occurrence of sticking. |
