Maintenance and troubleshooting methods of mine electric locomotives

Today, I will introduce the maintenance and troubleshooting methods of mine electric locomotives.
1. Check whether the lever and pin of the brake system are in good condition and whether the action is flexible.
2. Check the brake shoe wear, replace the brake shoe with over-value wear; check the gap between the brake shoe and the wheel tread, and adjust it in time if it exceeds the specified limit; clean the adjustment brake shoe screw and the mud on the brake shoe.
3. Check whether the wheel is cracked, whether the wheel tyre is loose, and the degree of wear of the wheel tread.
4. Check whether the reduction box has abnormal noise, whether the transmission gear and gear cover are loose and worn.
5. Check the frame spring for cracks and failures, remove the dirt on the spring, and lubricate between the hinge point and the balance beam.
6. Check whether the bolts and cotter pins of the car body and each part are complete, whether the bolts are tight, and whether the pin shaft and the cotter pin are well connected. In particular, the device that suspends the traction motor should be carefully inspected.
7. Check whether the coupling device is in good condition.
8. Check whether all parts of the sand removal system are complete, well connected, whether the sand pipe is blocked, whether it is aligned with the center of the track, and whether the distance from the wheel and the track meets the requirements.
9. Check whether the spring pressure of the receiver is sufficient, whether the slide plate is broken and worn out of limit, whether the frame, bolts and pins are complete and fully expanded.
10. Check whether the resistor is broken, whether the wiring terminals are loose, and clean the dust.

11. Check whether the master controller and other electrical equipment are operating normally, and whether the wiring terminals are firmly connected.
