Operating a rotary drilling rig safely requires strict adherence to a series of operating procedures and precautions to ensure equipment integrity, construction quality, and personal safety.#boring drill#
The following are some key safety operating points:
I. Pre-Operation Preparation
Reading Technical Documents:
Before using, operating, or performing any operations, carefully read all technical and operational documents provided by the manufacturer to understand the drilling rig's structure, performance, operating methods,
maintenance procedures, and basic drilling knowledge.
Training and Assessment:#boring drill#
Operators must undergo training and pass an assessment before operating the drilling rig independently.
Personnel who have not been trained or have failed the assessment are strictly prohibited from operating the machine.
Safety Inspection:
Check the levels of fuel, coolant, lubricating oil, and hydraulic oil to ensure the equipment is in good condition.
Simultaneously, perform maintenance on the equipment according to the shift maintenance requirements.
II. Precautions During Operation
Starting and Inspection:
Before starting the engine, ensure that the hand throttle and foot throttle are in low gear and check that all alarm devices are deactivated.
After starting the engine, run it at medium speed for 5 minutes to check for any abnormalities and for oil or water leaks.
Run the engine for half an hour before starting work to ensure all connections are correct and the oil temperature is normal.
Drilling Operations:
Understand the work environment. Observe the geological cross-section of the work area, overhead power lines, buildings, etc., paying particular attention to potential hazards such as gas pipelines, underground cables, and
high-voltage power lines.
When positioning the drilling rig, ensure the foundation is stable and the site meets the equipment stability requirements for drilling operations.
Slowly lower the drill bit to begin drilling, controlling the drill rod's descent speed to prevent rope tangling.
The pressure booster should be used in coordination with the drill rod's rotation speed to prevent slippage during drilling.
Do not forcefully lift the drill rod during drilling; release the soil's reaction force before lifting.
Real-time Monitoring:#boring drill#
During operation, constantly check the instrument displays and observe the main wire rope's working condition. If any abnormality is found, immediately stop the machine and address the issue.
Regularly inspect the drilling tools; replace severely worn drill teeth promptly.
Frequently check soil conditions; use appropriate drilling tools for different soil types.
Safety Operating Procedures:
Do not talk to others while operating the drilling rig, and the operator must not leave the cab.
When leaving the drilling rig, lower the drill rod to the ground and turn off the engine.
Do not blindly apply pressure; pressure should be controlled within a reasonable range.
During operation, if any red light (indicator light malfunctions) illuminates, stop the machine for inspection, identify the cause, and repair it before resuming work.
III. Non-Drilling Operations and Rig Transfer
Non-Drilling Operations:
All non-drilling rig operations must be conducted under unified command, and the commander must use standardized hand signals.
Ribbon Transfer:
During rig transfer, the mast must be lowered, the center of gravity must be appropriate, the road must be wide and compacted sufficiently, and the inclination must not exceed the specified value.
IV. Other Precautions
Wearing Protective Equipment:
During operation, all rig personnel must wear safety helmets, work clothes, and work shoes.
Prohibition of Alcohol and Medications:
Before or during operation, operators are prohibited from consuming alcohol, medication, or any food that may impair their operational ability.
Equipment Maintenance:
Regularly maintain and service the rig, checking the levels of engine oil, hydraulic oil, and gear oil, and inspecting the tightness of all bolts on the rig.#boring drill#
