What aspects should be paid attention to in the daily maintenance of anti-riot bollards?

Daily maintenance of bollards is crucial for ensuring stable performance, extending service life, and guaranteeing safety. Key aspects of daily maintenance are outlined below, covering hardware inspection, system function testing, environmental cleaning, troubleshooting, and management regulations:

I. Hardware Structure Inspection

1. Column Appearance and Structure

Surface Cleaning: Regularly wipe the column surface with a soft cloth or neutral detergent to remove dust, stains, and corrosive substances (such as oil stains and acidic/alkaline liquids), preventing rust or coating peeling on the stainless steel surface.

Damage Inspection: Check the column for dents, deformation, cracks, or weld cracking, paying particular attention to the stability of the connection between the column and the base. Repair or replace any problems promptly.

Sealing Performance: Check if the waterproof seals are aging or falling off, ensuring that the bottom and joints of the column are well sealed to prevent rainwater and sand from entering and damaging the hydraulic system or electrical components.

2. Hydraulic System Maintenance

Oil Condition: Regularly check the hydraulic oil level and quality (recommended every 3 months). If the oil level is low, add the same type of hydraulic oil; if the oil is cloudy or deteriorated, completely replace it and clean the oil tank to avoid clogging pipes or damaging the hydraulic pump.

Pipelines and Interfaces: Check the hydraulic pipelines for oil leaks, damage, or looseness, and check if the seals at the interfaces are aging. Tighten or replace components promptly to prevent a drop in hydraulic system pressure affecting the lifting speed.

Hydraulic Pump and Cylinder: Listen for any unusual noises during operation (such as harsh friction or vibration). If any are present, investigate pump wear, cylinder jamming, or air entering the system. If necessary, contact a professional for repair.

3. Electrical System Maintenance

Wiring Inspection: Check if the wiring in the control box is loose, aged, or damaged, and if the terminals are tight, to avoid equipment malfunction or short circuits due to poor contact.

Sensors and Switches: Test if the limit switches, proximity sensors, etc., are sensitive and reliable, ensuring that the column automatically stops when it reaches its position, preventing damage to the mechanical structure due to over-lifting or over-lowering.

Power Supply and Emergency Devices: Check if the power voltage is stable (usually AC 220V or DC 24V), if the backup power supply (such as the battery) is charging normally, and regularly perform charge and discharge tests (recommended every six months) to ensure the emergency lifting function is effective during power outages.

II. System Function Test

1. Lifting Operation Test

Regularly perform lifting tests (recommended weekly), observing whether the column lifts smoothly and without jamming, and whether the speed meets the design requirements (e.g., completing lifting within 3-6 seconds).

Test whether different control methods (such as remote control, buttons, remote platform) respond sensitively, and whether the interlocking control between columns is synchronized (if there is a multi-column interlocking requirement).

2. Anti-collision and Warning Function

Check the column's impact resistance (this can be done through a simulated low-speed collision test; avoid high-speed impacts). After confirming that the structure is undamaged, test whether the LED warning lights and reflective strips are working normally and whether the nighttime brightness is sufficient.

Verify that the emergency release function (such as the manual lowering device) is smooth in emergencies, ensuring that the passage can be quickly opened in case of power failure or system malfunction.

3. Safety Protection Mechanism

Test the anti-mistouch function: Ensure that unauthorized operations (such as accidentally pressing the remote control) do not trigger lifting, avoiding accidental injury to pedestrians or vehicles.

Check whether the linkage with other security systems (such as access control and monitoring systems) is normal, ensuring that the alarm signals are transmitted without error.

III. Environment and Cleaning Management

1. Surrounding Environment Cleaning

Promptly remove debris around the column (such as stones, fallen leaves, and snow) to prevent foreign objects from jamming the column or affecting drainage.

Check if the drainage system is unobstructed, especially the pit of the buried bollard, to prevent waterlogging of the equipment during the rainy season.

2. Extreme Weather Response

High-temperature environment: Avoid prolonged continuous lifting operations to prevent the hydraulic oil from overheating; check if the heat dissipation device (if any) is working normally.

Low-temperature environment: Use antifreeze hydraulic oil (such as -30℃ low-temperature oil), and regularly start the equipment for preheating to prevent the oil from solidifying and affecting lifting.

Typhoon or strong wind areas: If necessary, lower the column to a low position to prevent strong winds from causing the column to shake or the structure to be damaged.

IV. Troubleshooting and Professional Maintenance

1. Common Troubleshooting

The column lifts slowly or stops: This may be due to insufficient hydraulic oil, clogged pipelines, or oil cylinder leakage. Check the oil level, clean the pipelines, or replace the seals.

Control failure: Check if the power supply, wiring connections, controller, or sensors are malfunctioning. Prioritize restarting the equipment or replacing spare components for testing.

Unusual noise: This may be due to wear and tear of mechanical parts (such as gears and guide rails) or air entering the hydraulic system. Professional personnel need to disassemble and inspect.

2. Regular Professional Inspection

It is recommended that the manufacturer or professional technicians perform comprehensive maintenance every 1-2 years, including deep cleaning of the hydraulic system, aging detection of electrical components, and structural strength testing, to ensure that the equipment meets anti-riot standards (such as B1-level impact resistance).

Keep maintenance records, including maintenance time, content, and replaced components, to facilitate tracking of equipment status and predicting failures.

V. Management Regulations and Training

1. Operation Authorization Management

Only authorized personnel are allowed to operate the equipment to prevent misoperation or malicious damage by unprofessional personnel.

Regularly train operators to familiarize them with normal operating procedures, emergency handling methods, and safety precautions.

2. Emergency Plan Drill

Develop contingency plans for equipment malfunctions or emergencies (e.g., temporary access solutions when the bollard cannot be raised or lowered), and conduct regular drills to ensure a rapid response to unexpected events.

Summary

The maintenance of anti-riot bollards should follow the principle of "prevention first, combining prevention and treatment." Through daily inspections, functional tests, and professional maintenance, potential hazards should be identified and eliminated in a timely manner to ensure reliable performance in anti-terrorism, traffic control, and other scenarios. For complex malfunctions or structural safety issues, contact the manufacturer or a professional team immediately for assistance. Avoid self-disassembly to prevent greater risks.
