Heavy-load double-layer-loaded container rail wagon

Abstract

The invention relates to a heavy-load double-layer-loaded container rail wagon. The rail wagon is characterized by comprising a loading part and an end under frame, wherein the loading part is arranged in a well hole mode and comprises a well hole under frame, side walls and end walls; two 20-inch containers or one 40-inch container can be loaded according to the size of the well hole under frame; the two sides of the well hole under frame are welded and assembled with an inverted convex side wall respectively; the lower parts of the side walls are welded with a side beam respectively; the tops of the side walls are welded with a side wall upper edge beam respectively; a plurality of side wall vertical posts are arranged on the inner sides of the side walls at intervals; two ends of the well hole under frame are welded and assembled with an end wall respectively; the end under frame comprises a traction beam; and the traction beam comprises two traction beam web plates, a traction beam upper cover plate and a traction beam lower cover plate. By the rail wagon, three containers with the standard weight of 30.48 tons or four 20-inch containers with the total weight of less than or equal to 92 tons can be loaded, so that the condition of single-layer loading of the conventional double-layer container vehicle can be prevented, and the transportation capacity of the double-layer-loaded container rail wagon is greatly improved.

Description

Technical field [0001] The invention relates to a railway freight car, in particular to a railway freight car with large-load double-layer container loading. Background technique [0002] my country's railway container transportation has been carrying out double-deck container transportation since 2004. There are three types of container loading. One is to load two 20-foot containers on the lower layer and one container of 40 feet or more on the upper layer; the second is the lower layer. A 40-foot container is loaded, and the upper layer is loaded with a 40-foot or more container; the third type is to load two 20-foot containers on top and bottom. There are two types of 20-foot containers in my country, one is 24 tons, and the other is 30.48 tons. At present, the 20-foot container weighing 24 tons is no longer produced in my country and is gradually being eliminated. The standard weight of a container over 40 feet is only 30.48 tons. The total load of the existing double-deck ...

AI Technical Summary

Problems solved by technology

Therefore, it is very difficult to make up a double-layer loading method with a total weight of 78 tons during double-layer loading.

Therefore, at present, double-deck container vehicles basically use single-deck loading, resulting in a great waste of transport capacity
