A portable power head core drilling rig

Abstract

The invention discloses a portable core drilling rig with a power head, which comprises: a double-rail base, a guide rail, a sliding sleeve, a power head, a mast, a support rod, a clamper and a lifting oil cylinder, and the power head is installed and fixed on the sliding sleeve through a locking device. The mast is fixedly connected to the other end of the guide rail. The mast has fixed double support pulleys and a movable single support pulley; the support rod includes a main support rod and an auxiliary support rod, and the main support rod is respectively hinged between the end of the guide rail and the double-rail base. The auxiliary support rod is lapped between the guide rail and the double-rail base when the tower is lifted; the clamper includes the clamper body and the drill pipe stabilization ring, the drill pipe stabilization ring is composed of a stable bearing seat and a stable bearing ring, and the stable bearing seat and clamp One end of the holder body is fixedly connected, and the stabilizing bearing ring is installed in the stabilizing bearing seat, and the inner diameter of the stabilizing bearing ring is 1 to 2 mm larger than the outer diameter of the drill pipe. The portable power head rock core drilling machine of the present invention is convenient to disassemble and carry, and the drill pipe runs stably.

Description

technical field [0001] The invention belongs to the technical field of drilling equipment, and in particular relates to a portable power head core drilling machine. Background technique [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 bulky and heavy, which is not conducive to handling, installation and disassembly. Therefore, the fully 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 drill...

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
