Problems solved by technology

[0002] Existing core drilling rigs mainly include vertical-axis drilling rigs and full hydraulic power head drilling rigs. Although vertical-axis drilling rigs can drill holes with small inclination angles, it is difficult to satisfy inclined hole drilling with large inclination angles and a wide range of angle changes. The vertical shaft drilling rig is large in size and heavy, which is not conducive to handling, installation and disassembly. Therefore, the full hydraulic power head drilling rig overcomes the above-mentioned shortcomings of the vertical shaft drilling rig and is widely used in harsh environments such as the field and mountainous areas.
[0003] However, as the drilling depth increases and the rock drillability becomes poor, there are many problems in the existing power head drilling machine. The rod is difficult to lift, resulting in low work efficiency; at the same time, the service life of the power head is severely shortened due to the excessive swing of the drill rod

Abstract

The invention discloses a portable power head core drill. The portable power head core drill comprises a double-rail base, a guide rail, a slide bushing, a power head, a mast, supporting rods, a gripper and lift cylinders. The power head is fixedly mounted on the slide bushing through a locking device, and the mast is fixedly connected with the other end of the guide rail and provided with a fixed double-support pulley and a moving single-support pulley; the supporting rods include a main supporting rod and an auxiliary supporting rod, the main supporting rod is connectedly hinged between the end of the guide rail and the double-rail base, and the auxiliary supporting rod is in lap joint between the guide rail and the double-rail base during erection; the gripper comprises a gripper body and a drill stem stabilizing ring, the drill stem stabilizing ring consists of a stabilizing bearing block and a stabilizing bearing ring, the stabilizing bearing block is fixedly connected with one end of the gripper body, the stabilizing bearing ring is mounted in the stabilizing bearing seat, and the inner diameter of the stabilizing bearing ring is 1-2mm larger than the outer diameter of a drill stem. The portable power head core drill is convenient to assemble, disassemble and carry and stable in operation of the drill stem.
