Problems solved by technology
Existing vehicles generally have the problem of small door openings and inconvenient mechanized operations. The loading and unloading speed has become an important factor affecting the logistics speed
[0003] Express freight not only requires the vehicle to have a high running speed, but also should meet the requirements of "fast loading and quick unloading" of goods. At present, there is no railway wagon that can meet the requirements of "quick loading and quick unloading" of goods. Therefore, a kind of door opening with a wider width is developed. It is very necessary to have a railway express vehicle that is large, and any part of the side wall can be opened to facilitate the mechanized loading and unloading of forklifts and reduce the labor intensity of loading and unloading workers.

The invention discloses a folding door railway shed car. The folding door railway shed car comprises a car body frame structure and a folding door system, wherein the folding door system comprises anupper slideway, a lower slideway, a folding door assembly and a lower locking mechanism which are arranged on the car body frame structure. The folding door assembly is arranged between the upper slideway and the lower slideway and can slide back and forth along the upper slideway and the lower slideway, and the lower locking mechanism is arranged on the outer side of the lower part of a floor ofthe car body frame structure and used for locking or opening the folding door assembly.
Description
technical field [0001] The invention relates to a railway freight car, in particular to a railway box car with folding doors. Background technique [0002] With the development of my country's economy and the transformation of consumption patterns, the logistics market demand has shown explosive growth, and the transportation of frivolous goods with high added value has also grown rapidly. The main cargo products for luggage and postal transportation in my country are: special train for luggage and mail, special train for luggage and luggage, luggage carts hanged at the tail of passenger trains, and some ordinary boxcars. Existing vehicles generally have the problem of small door openings and inconvenient mechanized operations. The loading and unloading speed has become an important factor affecting the logistics speed. [0003] Express freight not only requires the vehicle to have a high running speed, but also should meet the requirements of "fast loading and quick unload...
