Description

Technical Field

[0001] This utility model relates to railway freight cars, specifically to a railway tank car for transporting powdery or granular materials. Background Technology

[0002] Existing railway freight cars generally include open wagons, flatcars, boxcars, and tank cars. Among them, open wagons, flatcars, and boxcars are equipped with a center beam structure in the longitudinal middle section. Since most existing railway vehicles use automatic coupler buffer structures, the two ends of the automatic coupler buffer structure are installed on the inner side of the two ends of the center beam structure. During the operation of the train, the longitudinal load is mainly transferred through the long center beam structure set in the longitudinal middle of the vehicle. This center beam structure can not only smoothly transfer the longitudinal load of the vehicle, but also ensure that the various structures of the vehicle are not damaged, thus ensuring the stability and reliability of the overall operation of the vehicle.

[0003] There are two types of railway tank cars: those with a center beam structure and those without. For tank cars without a center beam structure, the longitudinal load of the train is transmitted through the traction beams on both sides of the vehicle. After the longitudinal load is transmitted to the traction beams, it is transmitted upward to the tank body. Since the tank body of a railway tank car is generally cylindrical or near-cylindrical, it has high rigidity, so the longitudinal load can be transmitted through the tank body.

[0004] With the development of the times, the forms of materials transported by railway tank cars are becoming increasingly diversified. In order to better support the transported materials, the tank structure of the tank cars also varies depending on the materials. The existing railway tank cars for transporting powdery materials have a fluidized bed structure at the bottom. This fluidized bed structure occupies a large amount of space in the lower part of the tank car, which makes it impossible to arrange the central beam structure properly and the longitudinal load cannot be transferred. Due to the fluidized bed structure, there are large openings at the bottom of the tank car, which prevent the longitudinal load from being transferred through the tank body. Therefore, how to effectively transfer the longitudinal load on tank cars for transporting powdery materials and ensure the stability of the tank car structure and the reliability of its operation is an urgent problem to be solved.
