Rectangular tubes are widely used in the field of rail transit, and the following are some main aspects:
1.Vehicle body structure
Vehicle body frame: Rectangular tubes are often used to manufacture vehicle body frames for subways, light rails, high-speed trains, and other vehicles. Due to its high strength and stiffness, it can effectively reduce vehicle weight, improve operational efficiency and energy utilization while ensuring overall structural stability of the vehicle. For example, the body frame of some new subway vehicles is welded with high-strength rectangular tubes, which not only meets the strength requirements of the vehicle during operation, but also achieves lightweight design and reduces operating costs.
Door frame: The door frame needs to have a certain strength and stability to ensure the normal opening and sealing performance of the door. Rectangular tubes have good processing performance and can be bent and welded into various shapes to meet the complex structural requirements of car door frames. At the same time, the surface flatness of the rectangular tube is high, which is conducive to installing door sealing strips and other accessories, improving the sealing and sound insulation of the car door.
Window frame: Window frames are often made of rectangular tubes. The rectangular tube can be customized and processed according to the size and shape of the car window, providing strong support for the car window. In addition, rectangular tubes can also be improved in corrosion resistance and aesthetics through surface treatment processes such as spraying, electroplating, etc., to coordinate with the overall appearance of the vehicle.
2.Vehicle interior
Luggage rack: In train carriages, luggage racks usually use rectangular tubes as support structures. The strength of the rectangular tube can withstand the weight of luggage, and its simple appearance matches the interior style of the carriage. Moreover, the rectangular tube can conveniently install the shelves and other accessories of the luggage rack, making it easy for passengers to place their luggage.
Armrests: The armrests inside the carriage are generally formed by bending rectangular tubes. The diameter and wall thickness of the rectangular tube can be designed according to ergonomic principles, making passengers feel comfortable and safe when gripping the armrest. At the same time, the surface of the rectangular tube armrest can be treated with anti slip measures to improve the safety of passengers during vehicle operation.
3.Track system
Track sleepers: In some special track systems, such as bends or switch areas in urban rail transit, rectangular tube made track sleepers are used. This type of sleeper has high compressive strength and stability, which can better withstand the lateral and impact forces of trains at bends or turnouts, ensuring the geometric position of the track and the safe operation of trains.
Track guardrails: Track guardrails will be installed along railway lines and at the edges of subway platforms. Rectangular tubes are often used to make frame structures for protective fences due to their high strength and good rigidity. Guardrails can prevent personnel and objects from falling onto the track, ensuring the safety of passengers and staff.
4.Station facilities
Waiting seats: Rectangular tubes are usually used as chair legs and frame structures for waiting seats in subway stations and train stations. The robustness of the rectangular tube can withstand the weight of passengers, and its simple design also conforms to the overall architectural style of the station, while being easy to clean and maintain.
Platform canopy: The supporting structure of the platform canopy will use rectangular pipes. Rectangular tubes can form truss or frame structures, providing stable support for the canopy to withstand natural forces such as wind and rain, and providing a shelter for passengers waiting on the platform.
Escalators and stair handrails: The handrails of escalators and stairs are usually made of rectangular tubes. Rectangular tubes can be bent and processed according to the shape and size of escalators and stairs, providing passengers with safe and reliable handrail support, while also serving as decorative elements, making the public facilities of the station more beautiful.
