How To Properly Maintain And Care For Pneumatic Roofbolters?

Daily Maintenance and Inspection

1. Cleaning: Remove dirt, dust, and oil from the exterior of the rig to keep it clean. Pay special attention to ensuring all vents are clear; if blocked, unclog them immediately.

2. Tightening: Inspect all components, especially moving parts and easily loosened areas, ensuring bolts, nuts, and other fasteners are secure and reliable.

3. Lubrication: This is the core of maintenance. Regularly lubricate moving parts such as bearings to prevent damage from dry friction. Lubrication intervals will vary depending on workload and environment.

Fine Handling of Key Components

1. Cleaning the Motor Housing: During maintenance, open the motor housing and thoroughly remove internal impurities and old oil to prepare for subsequent operations.

2. Grinding Gear Burrs: Inspect the meshing surfaces of the gears and carefully grind away any burrs using fine sandpaper or a file to ensure smooth gear operation and reduce wear. 3. Bearing Installation: When installing bearings, ensure they are fully in place to avoid uneven loading and premature damage due to improper installation. Also, check the bearing preload to ensure there is no noticeable clearance.

Maintenance Cycle Recommendation: Based on comprehensive reference information, the recommended full maintenance cycle for pneumatic anchor drilling rigs is once every 1.5 to 2 months. This cycle applies to normal working environments. If the equipment operates in harsh environments with high dust and humidity, the maintenance cycle should be shortened to 30%-50% of the normal cycle, and dynamically adjusted based on oil condition monitoring.

Other Precautions:

1. Troubleshooting: During use, if noise, abnormal air pressure, or air leakage occurs, immediately stop the machine and troubleshoot. Only resume operation after troubleshooting to prevent accidents.

2. Long-Term Storage: If the drilling rig needs to be stored for a long time, in addition to the above maintenance, ensure sufficient grease is added to the gear reducer and all lubrication points, and perform rust prevention treatment on the pneumatic motor.
