A kind of boxcar with movable side wall for fast transportation with large volume

Abstract

The invention discloses a large-volume express covered truck provided with a movable side wall body. The large-volume express covered truck provided with the movable side wall body comprises a truck body, a braking device, a draw gear buffering device and a bogie. The truck body comprises an underframe, a side wall, end walls, a truck roof, side doors, middle doors and middle door columns. The side wall of the truck body is formed by combining fixed side wall bodies with the movable side wall body. The fixed side wall bodies are end side wall bodies arranged at the two ends of the truck body correspondingly. The movable side wall body is composed of the two push-pull middle doors and the two plug-pull side doors, and the two push-pull middle doors and the two plug-pull side doors are arranged between the end side wall bodies. Sealing is achieved through a sealing structure when the middle doors and the side doors are in the closed state. The end side wall bodies and the side doors are linked and locked through locking mechanisms, the side doors and the middle doors are linked and locked through locking mechanisms, and the middle doors and the middle door columns are linked and locked through locking mechanisms. According to the large-volume express covered truck provided with the movable side wall body, the truck body structure that the fixed side wall bodies and the movable side wall body are combined is adopted, so that goods loading and unloading are convenient and fast, and the volume is large; and the planar structural design is adopted for the outer wall of the truck body, so that the air resistance during fast traveling is reduced, and the traveling speed of the truck is increased.

Description

technical field [0001] The invention belongs to the technical field of railway wagons, in particular to a boxcar with movable side walls for large-capacity express transportation. Background technique [0002] Since the 1980s, express freight has developed rapidly in developed countries such as Europe and the United States. The speed of express trucks generally reaches 130-160 km / h, and the highest even reaches 270 km / h. Foreign railway express freight has narrowed the speed gap of passenger and freight transportation, better improved railway transportation capacity, and achieved remarkable results. The volume of foreign boxcars with movable side walls is generally 120 m 3 ~170m 3 . [0003] Since April 1997, our country has carried out a series of research and development of new express products, and formed three main types of express products, namely luggage express train / express postal train, five fixed trains and bulk direct trains. The vehicles mainly include P65 bo...

AI Technical Summary

Problems solved by technology

In order to ensure the flatness of the interior of the existing P65 and other ordinary boxcars, the side pillars, end pillars, and roof curved beams are placed on the outside of the carriage. Uneven, which increases the air resistance when the vehicle is moving fast

[0004] In addition, in order to improve operating efficiency, express vehicles mainly load and unload goods at night. At present, the goods transported by railway express are mainly light and frivolous goods, and their specific gravity is relatively small. The XL25T luggage car used for e-commerce trains will weigh about 15 tons after being filled with express goods. The volume of the vehicle is too small to meet user requirements

The door width of the XL25T is about 2.5m, and the door width of the P65 and other boxcars is about 3m. The door width is too small, resulting in a narrow loading and unloading operation channel, which is not convenient for fast loading and unloading of goods.

[0005] Moreover, there are no lighting facilities in the compartments of ordinary boxcars such as P65, and it is very inconvenient to pull wires and use electric lights or lanterns for lighting when loading and unloading at night; It is easy to be damaged by cargo or handling machinery during loading and unloading
