Adopting the technology wire line coring, the full hydraulic drilling rig driven with rotator, has been the dominant type rig for solid mineral deposits prospecting. It is also the developing direction of drilling technique and drilling equipment in China. Under these circumstances, we have developed the YDX-5C core drilling rig successfully according to the situation of China. This type of drill rig could substitute imported products. It could be used for exploration and prospecting of geology, metallurgy, coal, petroleum, natural gas, groundwater and other industries.
Main Technical Features
The main hydraulic pumps, valves and motors are all selected and put into use from famous international brands. There are two kinds of chassis for your selection and order. One is tyre-traction (with steering gear); Another is self-propelled steel crawlers. The rig equipped with hydraulic supports; Adopting hydraulic cylinder for lifting/lowering. The mast can be folded for its transport and location. With foot clamp touching the earth, the mast could work stably; The hydraulic system adopts load sensitive system; The rig is also equipped with high-position operation platform and operation hole platform (i. E. Low-position operation platform). The rotator is fed and driven with a system connecting the spindle and oil cylinder with chain. The system has the function, if the piston rod of oil cylinder moves one certain distance, the spindle will double the distance. The rotator has a long stroke. The rotator is driven by a single motor for its rotation. It is equipped with a four-speed gear shift, and its speed could be adjusted by hydraulic pressure with stepless speed change. The rig is also equipped with centering guide in its up part and guide in its lower part. A hydraulic clamp is adopted at the operation hole of the lower platform.
