Drilling Machines And Methods TRIZ Cases
- Rock Drilling Rig Stability Monitoring by Center of Gravity
Real-time center-of-gravity and support-pattern tracking helps rock drilling rig operators avoid instability in tight turns and uneven ground.
- Adjustable Coring Mast for Vertical Drilling on Angled Surfaces
A pivotable mast keeps the core bit vertical on angled surfaces, preventing uneven cores, bonding compound pooling, and bit sticking.
- Drilling Unit Distance Control for Accurate Rock Surface Positioning
Real-time radar or ultrasound scanning adjusts drilling unit movement to match actual rock surfaces and avoid manual plan rework.
- Rock Drill Protective Casing With Movable Fluid Feed-Through
A movable feed-through panel and closing arrangement keep rock drill fluid paths accessible while blocking rotating parts and reducing noise.
- Hydrostatic Drilling Transmission With Accumulator Pressure Support
An accumulator in the charge line buffers sudden load changes in a drilling transmission, preventing pressure drops that shorten pump and motor life.
- Portable Rock Drill Chassis With Remote Control and Guide Sleeve
A modular chassis, guide sleeve, and remote pneumatic control make rock drilling easier to transport, position, and operate safely.
- Expandable Reamer Ringout Detection Using WOB Ratio Changes
Surface and downhole WOB, torque, and ROP signals reveal expandable reamer ringout early, helping reduce drilling delays and wear uncertainty.
- Drilling Mast Counterbalance Valve Venting for Back Pressure Relief
An atmospheric vent passage in the mast counterbalance valve relieves actuator back pressure, protecting seals and eliminating long drain hoses.
