10.1 DRILLING FRAME
Drilling frame is one of the main components and can guide the sliding of rotating
assembly, drilling and lifting of drilling tool. It is box truss structure welded by U-steel and
with seat fixed at its toe to support the rod and drilling tool. Connected with compensation
cylinder and 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.
