8. Check the operation and wear of the buffer roller.

9. Check the operation of the tail roller.

10, do a good job inspection record.

Second, daily inspection

In addition to the contents of the class inspection, you should also pay attention to the following aspects:

1. Check and deal with problems that cannot be solved and handled by the class inspection.

2. Check the fasteners that are often in vibration during the movement, such as: drive device, transmission frame, tensioning winch and each roller installation positioning bolt, whether it is loose, if it is loose, it should be tightened.

3. Clean all key parts of the drive unit every day to clean up the dust and debris in time.

4. Check the gear unit and its lubrication system for oil leakage and handle it in time.

5. Check if the fluid coupling leaks oil and the use of the plum blossom elastic disk.

6. Check the contact between the machine head and the tail cleaner scraper and the conveyor belt, and replace the worn scraper in time.

7. Check if the tension of the conveyor belt is normal, and whether the pulley of the swimming trolley and the pulley of the tensioner are rotating normally.

8. Check if the joint of the conveyor belt is worn, whether the conveyor belt is deflected, whether the belt is pulled or not.

9. Each rolling bearing is oiled according to the working conditions.

10. Check whether the safety devices of the electronic control are normal.

11. Check the inspection records and carefully check the daily inspection records.

Third, the inspection

In addition to the contents of the daily inspection, you should also pay attention to the following aspects:

1. Check the working heat and stability of the motor and find that the abnormality is handled in time.

2. Check whether the action of the electric hydraulic pusher is normal, whether there is oil leakage, or whether there is oil leakage.

3. Check the daily inspection records and carefully prepare the inspection records.

Fourth, monthly inspection

In addition to the content of the inspection, you should also pay attention to the following aspects:

1. Check the oil level of the reducer and its lubrication system and refuel in time.

2. Whether the wire rope of the tension winch is worn, whether the pulley rotation is flexible, and the tension of the air belt is re-adjusted.

3. Check whether the fasteners of each component are loose, and find that they are loose and tighten immediately. For fasteners that are often in vibration during the movement, such as: drive device, transmission frame, tension winch and each roller installation and positioning Special attention should be paid to bolts.

4, check the inspection records, and carefully do the monthly inspection records.

1 There are anti-skid, coal -filling, anti-deviation, temperature (motor temperature), smoke protection, all kinds of protection, complete, sensitive, reliable, normal use, automatic sprinkler. 2 The nose has a protective fence, the tail is used to block the coal (矸) board, and there is a protective cover. The nose and the tail are fixed firmly, and the pedestrian needs to set a bridge across the bridge. 3 racks, the roller is fully finished, the rotation is flexible, and the belt does not run off. The 4H frame is laid flat, straight, stable, and numbered (the coal is painted sequentially from the inside to the outside; the boring is numbered by the nose to the tail), and the numbers are uniform. The 5 coal (矸) warehouse has a solid and reliable fence and a warning sign.
