It can better meet the requirements of diamond wire line coring, percussive rotary drilling, directional drilling, Reverse Circulation Continuous Coring (sample) and other drilling technologies to improve working efficiency.

Technical specification

Precautions for drilling rigs

(1) XY-2 drilling rig has a wide range of vertical shaft speed and a large number of speeds. There are nine forward gears and two reverse gears at 33-1002 / min.

It is beneficial to the selection of rotary speed for various drilling methods.

(2) It is equipped with a reverse torque device to stop the rotation of drill pipe (vertical shaft), which is very convenient for directional drilling.

(3) It can monitor and alarm the torque, WOB and other parameters. (configured according to user requirements)

High reliability of drilling rig

(1) It has the advantages of light vehicle gearbox, clutch, universal transmission shaft and other superior general parts, which are reliable in operation and long in service life

Q2) it adopts connecting rod force increasing spring central tightening, hydraulic loosening, normally closed hydraulic chuck, cemented carbide inlay welding slip structure, with large clamping force, long service life and reliable work.

(3) The hydraulic system of the drilling rig adopts three pumps for oil supply, which is well designed, reduces the heating of the system, and can be equipped with a variety of appliances to meet various requirements.

3, The drilling rig is equipped with hole bottom pressure indicator, which can be used to observe the hole bottom pressure from the table, and the drilling instrument is complete.

Characteristics:

1, the speed range is wide, the gear is reasonable.

2, low speed, large torque, can be used for drilling machine sampling and pile hole construction.

3, equipped with front-and-back moving cylinder, so the whole rig can move freely 300 mm, which brings a lot of convenience to the drill.

4, hydraulic feeding, easy to operate, high drilling efficiency and low labor intensity.

5. The chuck of drilling machine adopts hydraulic roller type, easy operation, reliable clamping and no damage to active drill pipe.

6, compact structure, small size, light weight.

7. Adopt 9 spring reinforced large torque clutch, reliable clutch, larger torque transfer, strong impact resistance and long life.

8, increase input shaft spline specifications, torsion resistance significantly improved, longer life.
