Embodiment Construction

[0016] The solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] The material loaded by the railway tank car of the present invention is a material that is solid under low-temperature transportation conditions (this type of material can be p-xylene). For the characteristics of this type of material, although in the process of unloading, the tank body can be heated by heating equipment It is heated to make it liquid; but because the existing railway tank car has a structure of loading and unloading, it seriously affects the unloading rate of the railway tank car, so it is necessary to improve the relevant structure of the tank body to increase the unloading rate.

[0018] Furthermore, the railway tank car of the present invention is aimed at the related structure that the tank body and the chassis of the current railway tank car are mostly connected by tank belts, which affects the imp...

Abstract

The invention provides a railway tank car which comprises a tank body, a tank car chassis assembly and a saddle pressing plate assembly, wherein the bottom of the inner wall of the tank body is provided with a liquid trap, the saddle pressing plate assembly comprises a pressing plate type connecting structure and a saddle for supporting the tank body, the bottom of the saddle is connected with the tank car chassis assembly, and the two ends of the saddle are fixed by the pressing plate type connecting structure. According to the invention, the liquid trap arranged at the bottom of the inner wall of the tank body of the railway tank car is used for realizing the effect of up loading and down unloading, and the defect that unloading rate is affected because of the up loading and down unloading structure adopted in the prior art can be solved; in addition, since the tank body and the tank car chassis assembly are connected and fixed by the saddle pressing plate assembly, the technical problem that the safety hazards exist in the prior art since the tank body and the chassis assembly of the railway tank car are mostly in tank belt connection can be solved further; therefore the railway tank car provided by the invention has the advantages of high unloading rate and reliable and safe operation.

Description

technical field [0001] The invention relates to the technical field of railway tank cars, in particular to a railway tank car for loading p-xylene. Background technique [0002] The freezing point of p-xylene is 13.2°C. After it is loaded into the tank truck in a liquid state, when it is transported at low temperature, the p-xylene exists in the tank in solid form. Although in the process of unloading p-xylene, the tank body can be heated by heating equipment to liquefy the solid p-xylene; The opening is provided with an unloading opening at its bottom, and the unloading opening is externally connected to a valve switch; if the unloaded p-xylene solidifies in the valve switch, it is easy to cause the failure of the valve switch and affect the unloading rate. [0003] Furthermore, at present, the tank body and the chassis of railway tank cars are mostly connected by tank straps, but with the increase of load and operating speed, this connection method of tank strap connectio...
