Product Description

rotary drilling rig type and anchor drilling machine (HFA7500)

Introduction                                                                                    


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.
