Three-decker railway freight car with detachable top decker

Abstract

The invention relates to a three-decker railway freight car with a detachable top decker, which is characterized by comprising a vehicle body of general double-decker car, wherein a floor punched with a plurality of rows of flued slotted holes for tying up automobiles is paved on the top of the second vehicle decker of the vehicle body, and hooking space for hooking of automobile reinforcing tying device is reserved between the floor and the second vehicle decker; meanwhile, guard rails capable of folding longitudinally along the vehicle are arranged on the second vehicle decker of the vehicle body, a piece of tarpaulin is covered outside the guard rails, the two sides of the tarpaulin are tied up and fixed on the guard rail by tying hooks, and the lower side of the end part of the tarpaulin is tied up and fixed on hooks arranged on the upper edge of the door frame at the end part of the vehicle body through tying hooks. In the invention, when the running interval of the vehicle is equal to a limit on standard track distance railway locomotive vehicles, the guard rails are laid down for loading on two deckers, so the safe run of the vehicle is ensured; and when the run interval ofthe vehicle is equal to a limit on double-decker container transport vehicles, the guard rails are raised for loading on three layers, so the freight volume of the vehicle is increased to a maximum degree, and the transport energy waste of the vehicle is reduced.

Description

technical field [0001] The invention relates to a railway freight car, in particular to a three-layer railway freight car with a foldable top floor for railway transportation of various types of medium and small cars. Background technique [0002] At present, the railway wagons used to transport various types of medium and small cars in our country are in the form of double decks. The main reason for this situation is the limitation of railway boundaries. There are two kinds of margins for railway rolling stock in my country, one is the standard gauge railway rolling stock margin stipulated in -1A of GB146.1-83 (such as figure 1 shown), and the other is the double-layer container transport vehicle limit stipulated in the "Railway Double-layer Container Transport Loading Limit (Provisional)" published by the Ministry of Railways in the Iron Technology Letter [2004] No. 157 (such as figure 2 shown). Due to the limitation of the management form of railway wagons in China, th...
