Historical Evolution‌

Origins‌:

Dating to the 2nd century BCE, early Chinese innovations utilized bamboo-and-human-powered "roller cone drilling rig" for rudimentary drilling.

By the 1950s, wire-rope percussion rigs were imported, followed by domestic development of cone-shaped drilling tools and hybrid systems.

Modern Advancements‌:

The 1960s–1970s saw breakthroughs like forward/reverse circulation rotary rigs and vibration-based underground drills.

Hydraulic-powered rotary rigs emerged in the 1970s, revolutionizing pneumatic systems for water well and core sampling applications.

Common Operational Challenges & Solutions‌

1. Ground Instability and Equipment Sinking‌

Issue‌: Host machines or hydraulic supports sinking due to soft terrain.

Solution‌: Deploy 3cm steel plates or Roadbed Box‌ to expand load-bearing surfaces, stabilizing the rig for drilling.

2. Abnormal Noises or Mechanical Vibrations‌

Issue‌: Irregular sounds indicating component misalignment or wear.

Response‌: Immediate shutdown to inspect bearings, rotary tables, or air supply lines. Replace damaged seals or lubricate moving parts.

3. Hard Rock Penetration Failures‌

Issue‌: Inability to drill through compacted soil or weathered rock layers.

Resolution‌: Use Chisel Hammer tools to fragment obstructions before resuming drilling. Avoid direct hammering on unyielding strata.

4. Air Pressure Fluctuations‌

Issue‌: Sudden drops/rises in pressure during pneumatic drill rig operation.

Diagnosis‌: Check for air leaks, clogged filters, or compressor malfunctions. Clean/replace filters and ensure valve integrity.

5. Hydraulic System Overload‌

Issue‌: Dashboard warnings or stalled progress due to excessive load.

Action‌: Monitor real-time pressure gauges; adjust drilling speed or reduce axial force to prevent component fatigue.

Best Practices for Maintenance‌

Regularly inspect universal joints, rotary couplings, and lubrication systems.

Clean debris from air vents and hydraulic lines to maintain airflow efficiency.

Train operators to recognize early warning signs (e.g., unusual vibrations, erratic gauge readings).
