A kilometer-level core drilling rig

Abstract

The invention discloses a kilometer-scale core drill which comprises a power assembly and a machine frame assembly, wherein the power assembly comprises an operating platform, a hydraulic oil tank, a diesel engine and a plurality of engines; the machine frame assembly comprises a double-rail pedestal, a big-frame guide rail, a power head and a power head saddle; one end of the big-frame guide rail is connected with a rotating shaft of the double-rail pedestal through a guide rail rotating shaft and the other end of the big-frame guide rail is fixedly connected with a first-level mast; a drilling rod holder is arranged at the connecting end of the big-frame guide rail and the guide rail rotating shaft; saddle oil cylinders are arranged on two sides of the big-frame guide rail and are used for driving the power head saddle to slide along the big-frame guide rail; the power head is arranged on the power head saddle; the other end of the first-level mast is connected with a second-level mast. The kilometer-scale core drill provided by the invention is convenient to disassemble, can drill deep holes and is convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of drilling equipment, and in particular relates to a kilometer-level core drilling machine. Background technique [0002] Core drilling rigs mainly include vertical shaft drilling rigs and full hydraulic power head drilling rigs. Although vertical shaft 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. Large volume and heavy weight are 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. As the drilling depth increases, the existing core drilling rigs have shorter drill rods and low drilling efficiency, making it difficult to adapt to deep space drilling. Contents of...
