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
The present invention relates to a kind of railway truck, particularly about a kind of heavy-load double-layer-loaded container rail wagon.
Background technology
China railways Container Transport started to carry out double-deck container transport from 2004, container loading has three kinds of forms, and a kind of is two 20 forty equivalent unit 40s of lower floor's loading, and one 40 feet or 40 feet of above freight containers are loaded in upper strata; The second is that 40 forty equivalent unit 40s load in lower floor, and one 40 feet or 40 feet of above freight containers are loaded in upper strata; The third is for respectively loading up and down two 20 forty equivalent unit 40s.China's 20 forty equivalent unit 40s have two kinds of weight, and one is 24 tons, and another kind is 30.48 tons.Current weight is that 20 forty equivalent unit 40s of 24 tons are no longer produced in China, and is eliminated gradually.More than 40 feet container standard weight only has 30.48 tons of one.The existing double-layer container vehicles of China loads gross weight and is less than or equal to 78 tons, and while only having one 40 feet of lower floor's loadings and upper strata to load a more than 40 feet freight container, load-carrying is less than 78 tons.Other load mode all needs to join case, particularly four 20 forty equivalent unit 40s of Double layer loading, want to allot the freight container possibility hardly that average case is heavily less than 19.5 tons, in addition China railways Container Transport is pressed case charge, the freight container of Different Weight mixes to be stacked, and 20 forty equivalent unit 40 quantity are in the great majority again.Therefore the Double layer loading mode that wants to gather out 78 tons of gross weights when Double layer loading is very difficult.So double-layer container vehicles adopts the situation that individual layer loads substantially at present, cause the significant wastage of capacity.
Summary of the invention
For the problems referred to above, the object of this invention is to provide that a kind of to load three std wt be the freight container of 30.48 tons, or four gross weights are less than or equal to the heavy-load double-layer-loaded container rail wagon of 20 forty equivalent unit 40s of 92 tons.
For achieving the above object, the present invention takes following technical scheme: a kind of heavy-load double-layer-loaded container rail wagon, it is characterized in that: it comprises loading part and end underframe, wherein said loading part adopts falling-hole form, described loading part comprises falling-hole underframe, side wall and headwall, and described falling-hole underframe size should be able to ensure to load two feet or a forty equivalent unit 40; Described falling-hole underframe comprises two curb girders that longitudinally arrange, and described in two, between curb girder, couples together with some horizontal tie-beams; Described falling-hole underframe both sides are the side wall of welding assembly one reversed convex type respectively, and described side wall two ends extend to top, vehicle sleeper beam end; Described side wall bottom respectively with described side beam welding, the each welding in described side wall top one side wall cantrail, described side wall cantrail two ends also extend to top, vehicle sleeper beam end; Described side wall clear width is provided with some side wall columns, and described side wall column upper end and the welding of described side wall cantrail, described side wall column lower end and described side beam welding; Described falling-hole underframe two ends respectively welding assembly one with inspection door and can bear the described headwall of vertical load, described headwall bottom is concordant with described curb girder bottom, described headwall top extends to concordant with described side wall top, and in the bending of described headwall upper press inverted L-shaped; Described end underframe comprises a draw beam, and described draw beam comprises two draw beam webs, a draw beam upper cover plate and a draw beam lower cover; Described in two, after draw beam web extend through vehicle sleeper beam, extend to form kitchen knife form downwards, described in two, draw beam web launches to form tubaeform to both sides simultaneously; Described draw beam upper cover plate covers edge on described draw beam web, and described draw beam lower cover is bent downwardly with described draw beam web after vehicle sleeper beam, launches to both sides simultaneously; After cutter head and exit skirt are placed in vehicle sleeper beam and described cutter head end and the welding of described headwall, it is that draw beam is born vehicle traction and brake load that hilt and loudspeaker nozzle are placed in vehicle sleeper beam previous crops; The draw beam base plate of a convex is welded in described cutter head bottom, described in described draw beam base plate extend through headwall to described curb girder bottom, and with described curb girder bottom and the welding of described headwall lower edge.
Between side wall column, be provided with diagonal brace, diagonal brace welds with the side wall column top and the bottom of both sides respectively.
Described horizontal tie-beam is horizontal or tilting, and connection mode adopts welding or riveted joint.
Adopt the L shaped steel of slab clod wash as described curb girder, and the reinforcement of opening upwards channel-section steel is set under it.
Adopt rectangular steel pipe as described side wall cantrail, adopt rectangular steel pipe or channel-section steel as described side wall column.
Between the cutter head of described draw beam and hilt, adopt great circle arc transition.
The present invention is owing to taking above technical scheme, it has the following advantages: 1, loading part of the present invention adopts falling-hole form, and the falling-hole underframe size of loading part can ensure to load two 20 feet or 40 forty equivalent unit 40s, making the present invention can load three std wt is the freight container of 30.48 tons, or four gross weights are less than or equal to 20 forty equivalent unit 40s of 92 tons, thereby can avoid the situation of existing double-layer container vehicles employing individual layer loading, greatly improve the capacity of Double layer loading Container car.2, the present invention is provided with diagonal brace between side wall column, and diagonal brace welds with the side wall column top and the bottom of both sides respectively, thereby increases the car body strength at vehicle falling-hole position.
