Machine Advantages
1. The drilling rig integrates mud rotary drilling and pneumatic impact drilling dual modes. Its high-performance mechanical top drive system can output a speed of 901 rpm and a peak torque of 9000 Nm. According to different formation characteristics, the equipment can intelligently switch the drilling mode: when working in soft soil layers, it is suitable for coreless drilling tools or conical drill bits to implement mud circulation drilling; when working in hard rock layers, it can implement high-speed rotary cutting and switch to the impact crushing mode of compressed air-driven down-the-hole hammer. Especially in complex working conditions such as loose gravel layers, the innovatively designed synchronous pipe drilling system can effectively maintain the stability of the hole wall.
2. The drilling rig is equipped with a 3500mm over-travel dual-speed propulsion mechanism, which significantly improves the proportion of pure drilling time by optimizing the feed speed to match the hardness of different rock formations. The unique dual-mode hydraulic drive system adopts intelligent split-and-joint flow control technology: the single pump energy-saving mode is enabled under drilling conditions, and the dual pumps are automatically switched to parallel oil supply during lifting operations to achieve the best balance between energy consumption and efficiency. According to actual measurements, this design reduces ineffective energy consumption by 40% and shortens auxiliary operation time by 35%.
3. The transmission system adopts a purely mechanical power transmission solution, and its energy conversion efficiency is increased by 100% compared to traditional hydraulic transmission drilling rigs. Combined with the modular drilling tool quick switching system, it not only eliminates common construction accidents such as drill jamming and overheating, but also increases the overall drilling efficiency by more than 50%. The whole machine achieves the simultaneous optimization of energy consumption and work efficiency through three core technological innovations: composite drilling mode, intelligent hydraulic distribution and efficient mechanical transmission.
