DSHD-600 sea engineering geological exploration drilling rig is a
top drive power head type drilling machine with long feeding
stroke. It adopted advanced technique of adjustable rotary speed
changer and is equipped with 12 or 8m high derrick. It can be used
to work under the condition of 80 m water depths and wind scale
less than 5 grade. It is also used for water area geological
exploration drilling and pile hole drilling in rivers or lakes.
Main set of drill can be used for drilling pile
holes on land.
1)Top drive power head of drill adopts frequency change
to adjust rotary speed steplessly. It features long feeding stroke,
compact structure, rational arrangement and wide regulating speed
range, with the result that drilling machine can meet the demand of
drilling in a great variety of complicated formation.
2)Safety and reliable falling-resistant apparatus of top drive
power head can ensure the safety of equipment and personnel.
3)Feed micro-adjusting mechanism of drilling machine can ensure
both equipment and personal safety.
4)Mechanization of break-out drill rods with hydraulic break-out
apparatus reduces labor strength and increase drilling efficiency.
5)Moving top drive power head rearward integrally ensures large
floor space and convenient for frequently hoisting
and lowering the drilling rod .
6)Equipped with the advanced bottom sampling device, it can meet
sampling demand in complicated formation.
