Tunnel Lining Trolley Maintenance Guide
я. Introduction:
Tunnel lining trolleys are critical for the safe and efficient construction of tunnel linings. Their robust construction is designed to withstand heavy loads and abrasive conditions, but regular maintenance is crucial to prevent premature failure and costly downtime. This guide is applicable to various types of tunnel lining trolleys, but consult the manufacturer’s specific documentation for detailed instructions and recommendations.
II. Безопасность в первую очередь:
Lockout/Tagout: Always follow proper lockout/tagout procedures before performing any maintenance. Isolate the trolley from power sources and ensure it cannot be accidentally started.
Personal Protective Equipment (СИЗ): Wear appropriate PPE, including hard hat, безопасные очки, перчатки, and steel-toed boots. Hearing protection may be required depending on the maintenance task.
Confined Space Entry: If working inside enclosed sections of the trolley, follow confined space entry procedures.
Qualified Personnel: Maintenance should be performed by trained and qualified personnel.
Manufacturer’s Manual: Always refer to the manufacturer’s manual for specific safety guidelines and procedures.
III. Regular Inspection Checklist:
Regular inspections are key to identifying potential problems before they lead to major failures. Frequency should be based on usage and environmental conditions, but daily pre-shift and weekly thorough inspections are recommended.
А. Daily Pre-Shift Inspection:
Визуальный осмотр:
Overall Condition: Check for obvious damage, трещины, износ подставки для ног и износ спинки сиденья, или чрезмерный износ.
Гидравлическая система: Inspect hoses, арматура, cylinders, and pumps for leaks.
Electrical System: Check wiring, connections, and switches for damage or loose connections.
Wheels and Rails: Inspect wheels for damage, носить, and proper alignment. Check rails for debris and obstructions.
Safety Devices: Verify the functionality of emergency stops, будильники, and limit switches.
Formwork: Inspect the formwork for damage, плохая группировка деталей, and proper alignment.
Operational Checks:
Движение: Ensure smooth and consistent movement of the trolley.
Hydraulic Functions: Test all hydraulic functions, например, подъем, lowering, and tilting.
Brakes: Verify proper brake function.
Осветительные приборы: Check the functionality of all lights.
В. Weekly Thorough Inspection:
All items from Daily Inspection.
Structural Components:
Welds: Inspect welds for cracks, коррозия, or signs of stress.
Bolts and Fasteners: Check for loose or missing bolts and fasteners. Tighten as necessary.
Рамка: Inspect the frame for deformation or cracks.
Гидравлическая система:
Fluid Level: Check the hydraulic fluid level and top off as needed.
Filters: Inspect and replace hydraulic filters according to the manufacturer’s schedule.
