Heavy-load double-layer-loaded container rail wagon

Abstract

The invention relates to a heavy-duty double-deck loaded container railway wagon, which is characterized in that it includes a loading part and an end chassis, wherein the loading part adopts the form of a drop hole, and the loading part includes a drop hole bottom frame, side walls and end walls, And the size of the drop hole chassis should be able to load two feet or one foot container; the two sides of the drop hole bottom frame are respectively welded and assembled with an inverted convex side wall, the lower part of the side wall is welded with the side beam, and the top of the side wall is welded with a The side beams on the side walls; a number of side wall columns are arranged at intervals on the inner side of the side walls; the two ends of the bottom frame of the drop hole are respectively welded to assemble an end wall; the end bottom frame includes a traction beam, and the traction beam includes two webs of cover plate and a drawbeam lower cover plate. The present invention can load three containers with a standard weight of 30.48 tons, or four 20-foot containers with a total weight less than or equal to 92 tons, thereby avoiding the situation that existing double-deck container vehicles use single-deck loading, and greatly improving the efficiency of double-deck container loading. The capacity of railway wagons.

Description

technical field [0001] The invention relates to a railway freight car, in particular to a large-load double-deck container railway freight car. Background technique [0002] my country's railway container transportation has started to carry 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 is loaded on the upper layer; the second is the lower layer. Load a 40-foot container, and load a 40-foot or more container on the upper level; the third is to load two 20-foot containers on the upper and lower sides. There are two weights of 20-foot containers in my country, one is 24 tons, and the other is 30.48 tons. At present, the 20-foot container with a weight of 24 tons is no longer produced in our country and is gradually being eliminated. The standard weight of containers above 40 feet is only 30.48 tons. The total loading weight of exist...

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
