Subway bolts are fasteners that play a crucial role in the construction and maintenance of subway systems.
Its characteristics are as follows:
1. High reliability: able to withstand strong vibrations, frequent impacts, and long-term fatigue loads generated during subway operation, ensuring the stability and safety of subway structures.
2. Strict precision requirements: high dimensional and thread accuracy to ensure accurate and tight connections, reducing the risk of looseness and displacement.
3. Corrosion resistance: It is usually treated with special surfaces or made of corrosion-resistant materials to cope with the corrosion caused by moisture, chemicals, and other substances in the subway environment.
4. High strength: It has sufficient tensile, compressive, and shear strength to adapt to the complex mechanical environment of the subway system.
The application range of subway bolts is wide, including:
1. Track fixation: Fix the steel rail firmly on the track bed or sleepers.
2. Vehicle structure connection: used for connecting key parts such as the body and bogie of subway vehicles.
3. Electrical equipment installation: Fix various electrical equipment and cable brackets.
In the selection and use of subway bolts, it is necessary to strictly follow relevant technical standards and specifications, conduct regular inspections and maintenance to ensure the normal operation of the subway and the safety of passengers.
The application scope of subway bolts mainly includes the following aspects:
1. Track system:
The connection between steel rails and sleepers ensures the stability and safety of the position of the steel rails.
Fixed components of the track bed to ensure the integrity of the track bed structure.
2. Vehicle manufacturing:
Connect various components of the vehicle body, such as the frame, side panels, etc.
Install equipment and facilities inside the vehicle, such as seats, armrests, etc.
3. Power supply system:
Fixed brackets and components for the overhead contact system.
Install substation equipment and cable trays.
4. Signal system:
Secure the brackets and boxes of the signal equipment.
5. Station construction:
Assemble and fix the steel structures of the station, such as platform canopies, stair handrails, etc.
Install ventilation, lighting, and firefighting equipment.
6. Tunnel facilities:
Fixed lighting fixtures, ventilation ducts, etc. inside the tunnel.
Subway bolts play an important role in connecting and fixing various components of the subway, ensuring the safe and stable operation of the subway system.
