Problems solved by technology
However, due to the large amount of rivets used in the side wall, the high rate of waste nails and the serious loss of special rivet equipment, the manufacturing cost of the side wall is much higher than that of the general welded side wall.
In addition, the windows of the current SQ5 and SQ6 are set on the side walls, and the upper chassis assembled in the car divides the car into upper and lower spaces, and the lower space has weak light

Embodiment Construction
[0016] The present invention will be described in detail below in conjunction with the accompanying drawings. However, it should be understood that the accompanying drawings are provided only for better understanding of the present invention, and they should not be construed as limiting the present invention.
[0017] Such as figure 1 , figure 2 As shown, the railway freight car side wall structure of the present invention includes an upper side beam 1, some side columns 2, some beams 3, some upper plane side wall panels 4 and some lower corrugated side wall panels 5;
[0018] The upper side beam 1 is divided into several single-leaf side wall frames through several side columns 2 arranged at longitudinal intervals, and several cross beams 3 are fixedly arranged at lateral intervals between the two side columns 2 of each single-fan side wall frame; The upper plane side wall panel 4 is fixed between the beam 3 in the middle of the wall frame, the upper part of the columns 2 ...

The invention relates to a side wall structure for railway freight cars, characterized in that the side wall structure includes an upper side beam, several side columns, several beams, several upper plane side wall panels and several lower corrugated side wall panels; The side beams are divided into several single-leaf side wall frames by a plurality of side columns arranged at longitudinal intervals, and a plurality of cross beams are fixedly arranged at horizontal intervals between the two side columns of each of the single-fan side wall frames; The upper plane side wall panels are fixedly arranged between the beams in the middle of the single-leaf side wall frame, the columns on both sides and the corresponding upper side beams, and the beams in the middle of each of the single-leaf side wall frames and the two sides The lower corrugated side wall panels are fixedly arranged between the columns so as to form a single side wall as a whole; the upper plane side wall panels of each single fan side wall are provided with louver ventilation holes and a car window at intervals from left to right, and adjacent to each other. The louver ventilation holes and vehicle windows of the two side walls are alternately arranged up and down on the upper plane side wall panels.
Description
technical field [0001] The invention relates to the technical field of railway transportation, in particular to a side wall structure for railway freight cars. Background technique [0002] In the early days, the side walls of special vehicles for double-decker railway transportation mostly adopted the structure of welding the flat plate and the side wall frame. The rigidity of the flat plate is small and the welding deformation is large, which affects the appearance quality of the vehicle. [0003] In recent years, the main type of railway transport vehicles such as SQ5 and SQ6 have adopted a riveted structure of corrugated plate side panels and side wall frames, which has a complex structure and good appearance quality. However, due to the large amount of rivets used in the side wall, the high rate of waste nails and the serious loss of special rivet equipment, the manufacturing cost of the side wall is much higher than that of the general welded side wall. In addition, t...
