The fully hydraulic power head core drilling rig adopting the rope core drilling technology has become the leading model for solid deposit exploration in developed countries, and has become the leading trend of drilling technology and equipment development in China.The rig can be used as an alternative to imports and is suitable for geological, metallurgical, coal, oil, natural gas, groundwater and other industries.
Technical characteristics
The hydraulic pump set, main valve and hydraulic motor are all imported from international brands. The motor unit and the reducer are fed into the lifting mechanism, and the long process is carried out; the spindle rotation adopts the double motor drive closed circuit, the second gear mechanical shift hydraulic stepless speed regulation; the mast uses the oil cylinder to rise and fall, has the touch function, foldable; the hydraulic system Load-sensitive control, crawler self-propelled; equipped with high-level workbench and orifice workbench; equipped with hydraulic leg device; upper right and lower guides; and hydraulic clamps at the orifice.
After 50 years of development, the company"s leading products have four series of more than 80 varieties: for exploration and drilling of 100-4200 meters deep solid deposits, engineering geological and hydrogeological exploration, shallow oil and gas exploitation, and mine tunnel ventilation and drainage Series of core drilling rigs for drilling; versatile drilling rigs for shale gas, coalbed methane drilling, shallow oil and gas drilling, oil well workover and geothermal well construction, and ultra-deep hole core exploration drilling; A series of engineering drilling rigs for drilling foundation piles of 0.8-3 m diameter bridges, highways, high-rise buildings, etc. in Quaternary gravel strata and hard strata; used for laying various pipelines through obstacles such as rivers, highways, railways, buildings, etc. (including power cables, telecommunications cables, heat pipes, gas pipes, water supply and drainage pipes, etc.), horizontally traversing the drilling rig with a pulling force of 150KN-15000KN.
