What Should We Pay Attention to When Using Underground Mining Electric Locomotives?
Operating underground mining electric locomotives is a critical task that requires a high level of responsibility and safety awareness. To ensure safe operation, operators should heed the following guidelines:
Monitor Bearing Temperature:
Pay close attention to the temperature of the axle box, motor bearings, and gearbox bearings to prevent overheating and potential damage.
Be aware of any burning smells, as this is a typical sign of overheating bearings.
Regularly check the bearing lubrication oil to ensure it is adequate and meets the required specifications.
Inspect the Brake System:
Regularly inspect the brake shoes for wear and replace or adjust them as necessary.
Ensure the brake system is functioning correctly, and that the braking distance meets specified requirements.
Periodically clean the brake system of dust and grease to maintain its cleanliness and efficiency.
Immediately Address Electrical Equipment Failures:
If any electrical equipment, lights, or horns fail, cease operations immediately and take the locomotive to the garage for repairs.
Do not continue to operate the locomotive with any faults, as this could lead to safety incidents.
Strictly Follow Shift Handover Procedures:
At the end of a shift, operators should conduct a thorough inspection of the locomotive, including:
Checking bearing temperatures, the brake system, and electrical equipment.
Inspecting the locomotive's exterior for any damage.
Listening for any unusual sounds from the locomotive.
Record all inspection results in the shift handover log to inform the incoming operator of the locomotive's condition.
Additional Precautions:
Adhere strictly to the mine's management regulations.
Familiarize yourself with the locomotive's operating procedures and maintenance methods.
Regularly participate in safety training and drills to enhance safety awareness and emergency response capabilities.
By strictly following these precautions, operators can effectively prevent accidents when using underground mining electric locomotives, ensuring their own safety and the safety of others.
The locomotive is a new product specially designed for large mines. It applies IGBT speed control way, realizes smooth starting and low failure rate, and is a new- generation energy efficient product. Main features include: small outer diamensions, short wheel base, small turn radius, high speed and strong traction force.
V-shape rubber damps are used on this locomotives in order to bear viration and impact from lengthways, vertical and transverse directons. The sails are elastic rubber plates which can ensure a reduced shock in operation.
