1.4 Electrical System Inspection
Check whether the cables and terminal blocks are firm and whether the insulation layer is intact.
Check whether the actions of the switches and buttons are normal.
Confirm that the motor operates smoothly without abnormal vibration or noise.
1.5 Inspection of drill pipes and drill bits
The threads at the connection of the drill pipe should be kept clean and undamaged.
Check the wear of the drill bit in a timely manner and replace it if necessary.
There are no obvious scratches or bending deformations on the surface of the drill pipe.
2. Regular maintenance
2.1 Comprehensive maintenance of the lubrication system
Regularly clean the lubricating oil circuit to prevent impurities from blocking it.
Replace the lubricating oil and grease at the prescribed intervals.
Use the recommended type and specification of lubricating oil.
2.2 Maintenance of Hydraulic System
Regularly change the hydraulic oil to maintain its cleanliness and viscosity.
Clean the hydraulic oil filter to prevent impurities from entering the system;
Inspect and replace aged or worn seals and valves.
2.3 Electrical System Maintenance
Regularly test the insulation resistance to prevent leakage and short circuits.
Check the motor bearings and add oil or replace them if necessary.
Test the sensitivity and response performance of electrical components.
2.4 Maintenance of mechanical Components
Check and adjust the clearance between the guide rails and the transmission mechanism of the drilling rig.
Check the wear of transmission components such as gears and chains, and repair or replace them if necessary.
Maintain the support system of the drilling rig to ensure its stability and safety.
3. Lubrication management
The good operation of the lubrication system is the key to ensuring the smooth operation of all moving parts of the anchor drill rig. Note:
Select lubricants that meet the manufacturer's requirements;
Arrange the lubrication cycle reasonably based on the operating time and working intensity of the equipment.
Key lubrication points include the main shaft bearings, hydraulic cylinder piston rods, gear transmission parts, guide rails, etc.
Prevent lubricating oil contamination and keep the lubrication environment clean.
4. Key points for Electrical System maintenance
Regularly clean the dust inside the electrical cabinet to prevent a decline in insulation performance.
Check the tightness of the terminal blocks and connecting parts.
Test whether the electrical protection device functions properly;
Regularly conduct tests on motor overload protection and control systems.
5. Fault Diagnosis and Elimination
The possible faults that may occur during the operation of coal mine anchor drill RIGS include insufficient power, drill bit slippage, hydraulic failure, electrical faults, etc. Maintenance personnel should:
Be familiar with the structure and working principle of the equipment, and master the common symptoms of faults.
Accurately locate the problem by using fault diagnosis tools and methods;
Handle the situation in an orderly manner according to the troubleshooting process to avoid blind disassembly.
Establish fault handling files for common problems to facilitate subsequent maintenance.
6. Safety Protection and Environmental Management
Regularly check whether the safety protection devices of the equipment are complete and effective.
Ensure the work site is clean and tidy to prevent dust and debris from blocking the equipment.
Operators must receive safety training and abide by operating procedures.
Regularly conduct safety drills to enhance emergency response capabilities.
Iii. Precautions for Maintenance and Care
Strictly abide by the maintenance manual of the equipment manufacturer and avoid blind operation.
Maintenance and upkeep should be handled by designated personnel, and a standardized work process should be established.
Maintenance records should be detailed and timely to facilitate subsequent tracking.
Use original factory accessories and recommended materials to ensure the performance of the equipment.
Regularly organize technical training to enhance the skill levels of maintenance personnel.
During the maintenance of the drilling rig, the power supply should be cut off to ensure safety.
Iv. Summary
As an important piece of equipment for mine support, the maintenance and upkeep of coal mine anchor drill RIGS are directly related to the safety and production efficiency of the mines.
