Product IntroductionShaft drill series is custom-developed for drilling in shaft sinking construction. It suits various vertical shaft projects and performs exceptionally well in large-diameter shafts with fluctuating rock hardness, delivering high construction efficiency and stable operation.
Supports a wide shaft diameter range with flexible operation and precise positioning. Driven by compressed air and hydraulic transmission, the rig realizes full mechanical movement. Equipped with a pneumatic rock drill, long feed stroke and parallel moving mechanism, it greatly improves blasthole drilling accuracy and efficiency, cuts auxiliary time substantially, and raises overall work efficiency by 30%.
| Structure Features & Working Principle: |
Power System: Pneumatic motor drives the hydraulic pump, combined multi-way valves to centrally control the cylinders, enabling automated positioning and fixing. Positioning Design: Key cylinders fitted hydraulic locks. Featuring high-rigidity boom and parallel movement mechanism, it delivers higher drilling accuracy and efficiency. Feed Mechanism: An adjustable feed force is achieved via cylinder-steel rope structure, adapting different rock layers stable rod extraction and strong power. Pneumatic Hydraulic Full Mechanization: Powered compressed air adopting hydraulic transmission technology, achieves full mechanization drillrig positioning, fixing, feeding, ensuring flexible precise operation. High Efficiency & High Precision Drilling: Equipped long feed stroke design parallel movement mechanism, paired pneumatic rock drill, it effectively improves blast hole accuracy efficiency, reduces auxiliary time, boosts work efficiency by 30%. Adaptive Feed Force Adjustment: Cylinder steel rope feed structure allows flexible adjustment feed force adapt different rock layers, ensuring stable rod extraction strong power. Reliable Structure & Easy Maintenance: Key components use hydraulic locks high rigidity boom designs improve positioning accuracy applicability. Simplified pneumatic motors reduce operating noise, standardized parts easy maintain and replace. Wide Applicable Shaft Diameter Range: Equipment offers broad adaptability various shaft diameters, meeting diverse vertical shaft construction requirements. |
