Railway tank car body and railway tank car

Abstract

The invention discloses a railway tank car body and a railway tank car, and belongs to the technical field of railway vehicle equipment.The railway tank car body comprises an underframe assembly, a tank body assembly and a loading and unloading system, the tank body assembly is installed on the underframe assembly through a tank body support assembly, and the loading and unloading system is installed on the tank body assembly; the tank assembly comprises a first cylinder and a second cylinder, the ends of the first cylinder and the second cylinder are in butt joint, and a set included angle is formed between the axes of the first cylinder and the second cylinder. The loading and unloading system comprises a bottom valve and a bottom valve control mechanism connected with the bottom valve, and an automatic ventilation valve is installed at the top of the first barrel or the second barrel and connected with the bottom valve through a linkage mechanism. The requirement for light weight of a vehicle body can be met, various light oil medium loading and unloading modes can be achieved, it is guaranteed that medium steam does not escape or leak and can be recycled, and the safety of a loading and unloading system under unforeseen circumstances is met.

Description

technical field [0001] The invention relates to the technical field of railway vehicle equipment, in particular to a railway tank car body and a railway tank car. Background technique [0002] The railway tank car is the main special-purpose vehicle used for loading goods such as gas, liquid (such as light oil), powder, etc. on the railway. At present, there are still some problems in traditional railway tank cars in terms of vehicle structure, vehicle weight, safety, and environmental protection. The specific problems are as follows: [0003] (1) The tank body of the existing railway tank car is usually a one-piece straight cylinder structure or a variable-section structure with a flat top and an inclined bottom (the bottom is inclined from the two ends of the cylinder body to the middle section), and the two ends of the tank body are installed on the On the bottom frame; the tank body and the internal medium are mainly supported by the bottom frame and end supports, and t...

Problems solved by technology

[0003](1) The tank body of the existing railway tank car is usually a one-piece straight cylinder structure or a variable section structure with a flat top and inclined bottom (the bottom is from the two ends of the cylinder to the middle section Downward slope), the two ends of the tank body are installed on the bottom frame through the end support; the tank body and the internal medium are mainly supported by the bottom frame and the end support, and the strength of the tank body itself is not enough; (2) The traditional railway tank car is generally The medium is loaded and unloaded through the manhole on the top of the tank body, which has a single function, and the manhole is kept open during the loading and unloading process, which may easily cause the medium steam to escape into the air and pollute the environment; (3) The structure of the existing railway tank car is relatively heavy and cannot meet the requirements.
