Hydraulic 250m Percussive Ground Anchor Drilling Machine
Product Description
The rig is the overall structure, can be adjusted in three
dimensions, achieve 360 ° construction, and is equipped with steel
crawler walking chassis, the machine moving quickly and convenience
of construction in different environment, gripper adopts double
clamping, can be achieved remove the drill pipe and casing
automatically. The device uses high pressure circulating water, and
using dynamic impact on double tube rotary drilling construction in
sandy pebble formation or unstable fracture formation construction.
The efficiency is higher than in the past conventional methods of
construction.
Full hydraulic pressure control, solid fuselage structure. Advanced
design concepts, monitoring instrument, convenient to
operation, ensure the practical performance. The equipment adopts
motor as the main source of power, And equipped with a 18 kw of
small diesel engine as power when walking , getting on and off.
Total power of 90 kw motor, power of head rotation is 65 kw, so the
drilling rig rotary torque is twice as large as the same type,
impact and the lifting force is very strong, high working
efficiency, and can be multi-usage, give priority to with slope
anchoring engineering construction, can also be widely used in
construction of deep foundation pit, subway, tunnel, railway and
the anchor construction of highway, geological disaster management
and a small pile of construction.
The Innovation Points
1. Use chassis of floating structure, can be change Angle of
departure of drilling rig and approach angle in a certain range;
2. Using large torque and hydraulic impact rotary power head, can
adapt to more than 95% of the formation of construction;
3. The structure of multidimensional connecting rod Angle changed,
can make the rig 360 ° in three-dimensional space arbitrarily
change the Angle of the borehole;
4. Using electric motor and diesel engine can cope with different
construction environment and construction conditions;
5. With double gripper can complete automatic shackle function;
6. Use chain times speed, large hydraulic feed, feed stable and
reliable, which can realize double pipe drilling, and following
pipe drilling.
