Proper operation of a rotary drilling rig requires strict adherence to safety regulations and operating procedures. The following are detailed steps and precautions:#hydraulic drilling rigs#
I. Pre-operation Preparation
Operator Qualifications: Operators must be professionally trained, familiar with the equipment's structure, performance, operating methods, and maintenance procedures, and hold relevant operating certificates.
Equipment Condition Check:
Check the performance and condition of components such as the engine, hydraulic system, drilling tools, and wire ropes.
Ensure all protective covers and safety devices are complete and securely fastened.
Check the levels of hydraulic oil, lubricating oil, and coolant to ensure they are normal.
Work Environment Check:
Ensure the work site is flat, firm, and free from settlement risks.
Check the work area for potential hazards such as underground cables, gas pipelines, and high-voltage power lines.
Personal Protective Equipment: Operators must wear safety helmets, work clothes, and work shoes.
II. Start-up and Preheating
Starting the Equipment: Press the start button to start the engine and check that all indicator lights are functioning correctly.
Preheating Equipment: During winter construction, the engine must be preheated for at least half an hour to ensure the temperature reaches the specified value before starting work.
Low-Speed Operation: After starting, run the equipment at low speed for 5-10 minutes to check that all component connections are normal.
III. Drilling Operation
Setting Drilling Parameters: Set appropriate rotation speed and feed rate according to geological conditions.
Starting Drilling:
Place the drill bit in the predetermined position, press the drill button, control the drill bit rotation, and gradually drill downwards.
During drilling, carefully observe the instrument display to ensure the drill rod is vertical to avoid affecting the hole quality.
Adjusting Drill Pressure: Adjust the drilling pressure according to geological conditions, avoiding blindly increasing pressure. Control the boost pressure at approximately 300 Pa and the rotation pressure at approximately 100 Pa.
Inspecting Drill Bits: Regularly check the wear of the drill bits and replace severely worn drill teeth promptly.
IV. Precautions During Operation
**Instrument Observation:** Constantly monitor instrument displays and check the working status of components such as the wire rope and hydraulic system.#hydraulic drilling rigs#
**Abnormalities Handling:** If abnormal noises, deformation, overheating, or smoke are observed, stop the machine immediately for inspection.
**Soil Disposal:** Select appropriate disposal locations during drilling to avoid affecting the drilling rig's rotation.
**Mud Management:** Clean the mud circulation pool promptly to prevent mud leakage.
V. Post-Operation Maintenance
**Equipment Cleaning:** After operation, clean the drill bits and equipment surfaces of mud and dust.
**Bolt Inspection:** Check the tightness of all bolts on the machine, especially those at the drill rod connection on the upper part of the drill mast and the wire rope connection.
**Lubrication and Maintenance:** Add lubricating oil every five hours of operation and check the levels of hydraulic oil, gear oil, etc.
**Equipment Parking:** Lower the drill mast and park it on a level surface. If necessary, wed the tracks to prevent slippage.
VI. Safety Precautions
**Prohibition of Unauthorized Personnel:** During operation, unauthorized personnel are prohibited from entering the operator's cab or remaining on the tracks and frame.
**Work Stoppage in Severe Weather:** In case of winds exceeding level 6 or thunderstorms, the mast should be lowered, power disconnected, and operation ceased.
**Nighttime Operations:** When operating at night, ensure the drilling rig has adequate lighting and the work area has sufficient illumination.
By strictly adhering to the above operating procedures and safety regulations, the construction efficiency and safety of the rotary drilling rig can be effectively improved, and the equipment's service life extended.#hydraulic drilling rigs#
