Large-volume dry bulk cargo transportation container for railway

Abstract

The invention relates to a large-volume dry bulk cargo transportation container for a railway. The large-volume dry bulk cargo transportation container is characterized by comprising a container bottom assembly, four bottom corner pieces, two side wall assemblies, an end wall assembly, an end door assembly, four top corner pieces, a container top assembly, a soft rope and a PVC (poly vinyl chloride) tarpaulin, wherein the container bottom assembly is connected with the bottom parts of two side wall assemblies, the end wall assembly and the end door assembly through the four bottom corner pieces, the top parts of the two side wall assemblies, the end wall assembly and the end door assembly are connected with the container top assembly through the four top corner pieces, and the container top assembly is fixedly provided with the PVC tarpaulin through the soft rope. The large-volume dry bulk cargo transportation container has the characteristics of large volume, long service life, and good adaptability of cargo to the container. The large-volume dry bulk cargo transportation container can be widely applied to the railway transportation field.

Description

technical field [0001] The invention relates to a railway freight container, in particular to a railway large-volume dry bulk cargo transportation container. Background technique [0002] With the continuous development of my country's national economy, railway freight transportation has the advantages of low energy consumption, low cost, large volume, all-weather, safe and reliable, and railway container transportation is also fast, safe and "door-to-door". The time sensitivity of transportation can realize stable, fast and punctual loading and unloading, weaving, transportation and transit of goods. Therefore, in order to adapt to the characteristics of cargo transportation, in recent years, my country's railway container types have been continuously promoted, and special container types such as dry bulk containers, automobile containers, and bulk cement tanks have been fully developed. [0003] Containers have fixed external dimensions according to series and box type. Fo...

AI Technical Summary

Problems solved by technology

[0004] At present, the railway dry bulk container is limited by the external size, so the internal size can only be increased to the maximum to increase the volume, which results in insufficient structural strength and rigidity margin of the box body, and frequent failures of the box's external expansion, especially the end wall structure The external expansion permanent deformation that occurs when subjected to a large longitudinal impact force under the conditions of railway transportation shunting, emergency braking, etc. may cause the container length to be out of tolerance, affect container loading and stacking, and bring safety problems to transportation and storage

In addition, the current railway dry bulk container generally adopts a steel box roof to increase the ability of the box body to resist external expansion, and only two or three top openings are opened on the top of the box, which is only suitable for mechanical loading of dry bulk cargo in a static state Or fixed leakage warehouse loading, which cannot meet the dynamic loading of the ring line fast packing, and the loading efficiency is low

Moreover, the small top port is not suitable for top-lift loading of large cargo, and can only be loaded through the end door wheel. The loading equipment required is complicated, and the convenience and flexibility of loading and unloading need to be improved.
