Compared with the existing side wall structure 20, the side wall structure 20 arranged above has the advantages that the height of the side wall plate 201 is increased and is basically higher than that of the end wall structure 30, so that the volume of a carriage can be increased under the condition that the dead weight of a vehicle body is hardly increased, and the end wall structure 30 is not increased, so that the interference with a leakage bin is avoided. The railway wagon can generally drag a plurality of carriages per train, such as the railway wagon, and the number of carriages of a part of wagon types can reach 250, so that the loading capacity of the whole wagon can be greatly improved by increasing the volume of a single carriage.

In addition, on the premise that the height of the side wall plate 201 is increased, notches 20a are reserved at the two ends, the bottoms of the notches 20a are flush with the end wall structure 30, namely the bottoms of the notches 20a and the end wall structure 30 still keep the same height, and the positions of the notches 20a correspond to the position of the pressure head of the car dumper, namely the car dumper can still work and is not affected by the increase of the height. At this time, the reinforcing plate 203 is provided at a position corresponding to the notch 20a inside the side wall plate 201, so that the cargo is prevented from leaking out from the position of the notch 20a, and the strength of the notch 20a is increased.

Specifically, the reinforcing plate 203 is not limited to a flat plate structure, as shown in fig. 3, the reinforcing plate 203 is a three-dimensional structure and includes a back plate and two side plates 203c, the back plate faces the opening 20a and includes an upper back plate 203a and a lower back plate 203b connected up and down, the bottom edge of the lower back plate 203b is connected to the inner side of the side wall plate 201, the upper back plate 203a can be arranged substantially parallel to the side wall plate 201, the lower back plate 203b is arranged obliquely relative to the upper back plate 203a, the back plate is recessed relative to the side wall plate 201, and two side edges of the back plate are connected to the side wall plate 201 through one side. So set up, opening 20a position department has bigger horizontal space to provide bigger space, the operation of the tipper of being convenient for.

The sidewall structure 20 further includes an upper side beam 204 in a zigzag shape, i.e., as shown in the black part in fig. 6, for convenience of description, the upper side beam 204 is defined in sections, the upper side beam 204 includes a first low section 204b, a high section 204a, a second low section 204e, a first connecting section 204c for transitionally connecting the first low section 204b and the high section 204a, and a second connecting section 204d for transitionally connecting the height and the second low section 204e, and the first connecting section 204c and the second connecting section 204d may extend from top to bottom along the outer surface of the sidewall plate 201, or may be inclined at a certain angle.
