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.
