XL-3 Pneumatic (DTH) Hammer Rotary Engineering Jet Grouting DrillIing Rig
Applicable to different construction the railways, highways, bridges, dam foundation, and various industrial and civil building foundation treatment and reinforcement of jet grouting construction; Anchorage engineering of foundation pit support; Matching with air compressor and pneumatic DTH hammer, it can be used for pipe drilling, general rotary spraying (swing spraying, fixed spraying) engineering construction, but also for shallow hole drilling and engineering survey drilling and other engineering construction.
Drilling rig advantage:
1. Multi-directional luffing mechanism, the drilling rig can realize multi-row and multi-angle drilling in one position, with strong adaptability;
2. Large rotation torque and long travel distance, it can effectively improve drilling efficiency;
3. It’s convenient and quick to move that the drilling rig has self-traveling function, with a 360° slewing device.
4. Shorten the time of drilling up and down and reduce the labor intensity, the holes are equipped with hydraulic clamps and shackle devices,
5. The handles are reasonably arranged with flexible an convenient control, and equipped with dynamic parameter display control system (patented technology), which can control various parameters such as the engine speed, oil temperature and water temperature, hydraulic system pressure, mud pump pressure, drilling depth, hole bottom pressure in time, easy to control drilling.
6. Saving the time of changing the drill pipe and improving the drilling efficiency, 12 m height of the mast can handle 16m standing rob, and the drill rob centralizer is added to facilitate the lifting of the drill tool.
7. The speed change of the power head adopts the combination of variable hydraulic motor and gearbox, the speed range is wide and reasonable, and the drilling rig has strong applicability to the stratum and different drilling process.
8. The upper and lower hydraulic chucks adopt butterfly springs, which are clamping tightly, increasing stroke after loosening, and have the function of automatic slip wear compensation, which effectively improves the life of the spring and slips;
9. The main components of the hydraulic system of the drilling rig are imported well-known brands, and the general components are selected from domestic well-known brands. The system is stable and safe for a long service life;
10. Adopting direct-acting load feedback fine-tuning variable hydraulic system, power changes automatically with bearing load, high efficiency, low energy consumption;
11. The handles are arranged for flexible and convenient control, and equipped with digital instruments, which shows the engine speed, oil temperature, water temperature, hydraulic system pressure and different parameters in time. It facilitates the control of drilling.
XL-3 crawler-type full-hydraulic multifunction jet grouting drilling rig is suitable for different requirements such as high-pressure jet grouting, jet grouting anchor cable, rock bolt supporting, single-tube, double-tube and triple-tube spraying (swing spraying, fixed spraying, intermittent lifting), spraying anchor rope. And it is also applied to cemented carbide rotary drilling, screw drilling, pneumatic down-the-hole hammer drilling, pneumatic (DTH) hammer drilling with simultaneous casing tool (following pipe),engineering exploration and other drilling techniques
