Full Hydraulic Core Drill Rig Type BEST-CR8 For Geological Mining Drilling
BEST-CR8 Full Hydraulic Core Rig -- an up-to-date Multifunctional
and high capability product is a thoroughly new-type hydraulic
core drilling developed with reference of HYDX-series Full
Hydrau-lic Core Rig and feedback of clients. It is suitable to be
used in plains, hills, as well as severe atmosphere places and
conditions such as high temperature and cold weather. It is mainly
used for metal & nonmetal solid mineral exploration and
exploration of coal-bed methane, natural gas mining; hydrogeology
well dillig, geothermal well driling, mining gallery, ventilation
and drainage of exploratory and emergency construction project. It
can also be mainly used in the field of geology, metallurgy, coal
mine, non-
ferrous mining and oil, hydrological and engineering drilling. It's
one of the multifunctional and excellent performance core rig by
using diamond and carbide-tipped bits mainly and the same time it
can meet the demand of wire-line coring and top drive,optional
bracket device optional bracket device.
1. Full hydraulic drive, steel Crawlers, assembly type mast, the
machine is integrated and compact for easy operation in
structure consisting of power station, main hoist, wire line winch
and mud pump, etc.
2. It is adopted dual pump and motor and closed-loop hydraulic
circuits for rotation of unit head; and open-loop design is
adopted for all other hydraulic transmission. It is adopted
precursor control and load-sensing for the hydraulic system. The
system
is controlled by electro-hydraulic proportional integratedly and
intensively.
3. The structure of doubling system between cylinder & chain is
adopted for the feeding and lifting of drill head, i.e. with the
function, if the piston rod of oil cylinder moving one certain
distance, the spindle movement will double the distance. Lifting
capac-
ity and feeding capacity is separately upto to 295 kN, 152kN.
4. Rotation of drill head spindle is driven by dual-motor with
closed loop hydraulic circuits, aided with three-speed mechanical
gearbox. Max torque of spindle out-put can be up to 7200
N.M(170rpm), and the torque at high speed is increased
efficaciously.
5. Adopting translational device drived by hydraulic motor to the
drill head, this make the spindle move away from the drilling
hole thoroughly and this is easier for the wire-line coring
operation and the in-hole work requirement.
6. Convenient for making-up and shackle in the duration of
drilling, shackles is adopted in the front of mast. This will
reduce
the intensity labour of operator and increase the work efficiency.
7. It's easier for operators to get on and off the worktable and
convenient for their operation on the panel.
8. The hydraulic clamp and centralizer are adopted to the top of
drlling hole.
