20 daily maintenance rules for China mining electric locomotives

Mining electric locomotives are mainly used for underground transportation and long-distance transportation on the ground. It is equivalent to the electric locomotive in railway transportation. It hauls a train consisting of a mine car or a man-carriage to walk on the track. The electric locomotive that completes the transportation of coal, gangue, materials, equipment, and personnel is called a mining electric locomotive. Components The mine electric locomotive consists of a mechanical part and an electrical part. Let's take a look at what are the 20 daily maintenance rules for mine electric locomotives?

1. Check whether the air compressor is operating normally, whether the air duct is leaking, and release the waste oil and water in the air storage tank;

2. Check whether the commutator, carbon brush and brush holder of the air compressor motor are normal;

3. Check the spring pressure of the receiver, the degree of wear of the skateboard, and whether the receiver is flexible and complete when it rises and falls;

4. Check the terminals and resistance elements of the resistors, and they shall not be loose or broken;

5. Use a dust blower or clean cotton wool to remove the dirt and dust inside the switch, and keep all parts clean;

6. Check whether the fastening parts such as screws and nuts are firm and reliable, and whether the contacts are loose;

7. Check and adjust the contact disconnection distance and rolling distance;

8. Check whether the arc extinguishing cover is damaged and whether the fastening bolts are loose;

9. Check whether the insulation of the inner wall of the metal shell and the insulation bottom plate are intact;

10. Check the metal shell for deformation and damage.

11. Check the wear condition of the brake shoes, replace the brake shoes, and adjust the brake shoe gap.

12. Check whether the brake of the brake system, the transmission rod (chain) and its connecting parts are normal and complete.

13. Check whether the wheel is cracked, whether the wheel tyre is loose, and whether the wheel tread wears depth.

14. Check the contact, wear and burn marks of the contacts. If there is burn mark, it can be processed and repaired with a fine file;

15. Check whether the armature device, tension spring, and tension rod are damaged, whether the compression spring on the moving contact is broken, whether the trip device is flexible and reliable, and whether there is jamming or failure;

16. Check whether the insulation performance of the live conductor parts on the shell is reliable;

17. Check whether the gear box (cover) is firmly fixed and whether there is oil leakage;

18. Check the frame spring, hanger, balance beam for cracks and severe wear;

19. Check the connection device, there must be no damage and wear exceeding the limit;

20. Whether the sanding device is flexible and reliable, and whether the sand outlet is aligned with the center of the rail surface;

To The above clearly organized content is our detailed introduction to the maintenance work after the use of the mine electric locomotive. A machine with good performance has brought us high efficiency and requires our careful care and maintenance. In this way In order to ensure that the future work efficiency has been maintained at this level.
