What Checks Should Be Prioritized before Starting A Rotary Drilling Rig

The inspection before the start of a rotary drilling rig is a crucial step to ensure construction safety and prevent equipment failure. It can effectively reduce the probability of downtime for maintenance during operation and lay a foundation for efficient construction. These inspections need to cover the core systems and key components of the equipment to ensure that each item complies with safety operation standards.

1. Power system inspection: Focus on checking whether the engine oil level and coolant level are within the standard range. At the same time, inspect the quality and reserve of fuel. If the engine oil deteriorates or the fuel is insufficient, it may cause difficulty in starting the engine or cause it to stall halfway, affecting the construction progress.

2. Hydraulic system inspection: Check whether the oil level in the hydraulic oil tank is normal, and inspect the hydraulic pipelines and joints for any leakage marks. If the hydraulic oil is insufficient or there is pipeline leakage, it will cause the drill pipe to move slowly, such as lifting and rotating, and may even lead to safety accidents.

3. Inspection of drill tools and drill pipes: Observe whether the cutting edge of the drill bucket is worn or deformed, and check whether the bolts at the connection points of the drill pipes are tightened. If the drill tools are damaged or the drill pipes are loose, problems such as bucket dropping and hole wall collapse may occur during drilling, increasing the construction risk.

4. Electrical system inspection: Test the sensitivity of the start switch and operation handle, check whether the indicator lights and warning devices on the instrument panel are normal, and ensure that the circuit connection is not loose to avoid misoperation or sudden shutdown of the equipment due to electrical faults.

5. Brake and travel system inspection: Check the braking effect of the service brake and parking brake, and examine the wear and tightness of the tracks or tires. If the brakes fail or the travel components malfunction, it will affect the safety of equipment movement and may even cause accidents within the site.

6. Safety protection device inspection: Confirm whether the guardrail in the cab, emergency stop button, warning light and other devices are in good condition. Check whether the safety warning signs within the operation range are clear. Missing or damaged protection devices need to be repaired in time to ensure the safety of the operators.

In conclusion, the inspection of a rotary drilling rig before its operation should focus on the two core aspects of "safety" and "performance", covering key systems such as power, hydraulics, and drilling tools. Only by conducting item-by-item inspections and promptly eliminating potential hazards can we prevent equipment from operating while faulty, ensuring the safety of operators and reducing downtime due to faults, thereby enhancing overall construction efficiency.
