SWDE120A DOWN-THE-HOLE DRILLING RIG OPERATOR’S MANUAL BOOK
sliding guide groove, slide frame, it could slide up and down. Lift compensation cylinder, it
would raise, push out compensation cylinder, its lower supporting seat would be on working
surface.
10.2 SLIDE FRAME
Slide frame is square box structure welded by steel plate. Its function is supporting and
connecting drilling frame. It is hinged by shaft and machine frame bracket. Lifting or falling of
the slide frame and drilling frame assembly, and drilling direction changing are realized by
controlling of lifting cylinder.
10.3 ROTATING MECHANISM
The rotating mechanism consists of hydraulic motor, main shaft units, connectors, slide
plate and central air supply units. Chains of feeding mechanism are fixed on the slide plate
through shaft and spring shock absorb.
Rotating is driven by two units’ hydraulic motor. The output rev ranges 0 ～ 60rpm after
decelerated by gear box.
10.4 FEED MECHANISM
Feed mechanism consists of hydraulic motor, roller group, chain and buffer spring. One
end of the chain is fixed on upside of slide plate by shaft after rounding driving roller, the other
end is fixed on buffer spring after rounding trailing roller. Buffer spring is connected to down
side of slide plate. By operating hydraulic motor, machine would propel or lift. There is buffer
function when feeding hydraulic motor.
10.5 ROD UNLOADER
Rod UNLOADER consists of up rod discharging body, low rod discharging body, up tongs
mouth, low tongs mouth, rod clamping cylinder and rod discharging cylinder etc. Clamp the up
and low rod by rod clamping cylinder, then operate the cylinder to loose the up and low rod
connecting screw to separate the rod. Lastly, discharge the rod machine by controlling rotating
