Abstract

The embodiment of the invention provides a supporting structure of the two-layer floor of a double-layer train and a double-layer train. The supporting structure comprises a plurality of fixing seats,a plurality of supporting seats, and supporting beams; the fixing seats are fixed at intervals along the side wall cross beam of the double-layer train; the supporting seats are fixed to the side wall stand columns of the double-layer train respectively; each supporting seat is fixed to one corresponding side wall stand column; and the supporting beams are used for fixedly connecting the fixing seats and the supporting seats and fixing the two-layer floor. The double-layer train comprises the supporting structure of the double-layer floor of the double-layer train. With the supporting structure and the double-layer train adopted, the technical problem of low flatness of the side wall of the train body due to the large welding and fixing area of the supporting structure of the two-layer floor of the double-layer train and the side wall of a train body is solved.

Description

technical field [0001] The present application relates to the technical field of electric locomotives, in particular to a support structure for a second floor of a double-decker train and a double-decker train. Background technique [0002] Double-decker trains are mostly made of aluminum alloy, and the later maintenance costs are extremely high. Such as figure 1 and figure 2 As shown, the car body side wall 10 of a double-deck train is welded and fixed with a support structure 20 , and the support structure 20 supports and fixes a second floor 30 . Since the entire side of the support structure 20 is welded to the vehicle body side wall 10, it needs to be realized by arc welding, and the heat input during arc welding is large, which will cause a large welding deformation at the welding position of the support structure and the vehicle body side wall, and further The flatness of the side wall of the car body is lower. [0003] Therefore, how to reduce the area where the...
