The invention relates to the technical field of railway vehicles, in particular to a depressed center flat car. Comprising a concave bottom frame device, the concave bottom frame device comprises an upper cover plate, a lower cover plate and a supporting structure, the upper cover plate and the lower cover plate are distributed at intervals in the vertical direction, and the supporting structure is arranged between the upper cover plate and the lower cover plate and comprises a supporting plate; the supporting plate is obliquely arranged relative to the upper cover plate and/or the lower cover plate, and the two ends of the supporting plate are connected with the upper cover plate and the lower cover plate respectively. The concave bottom frame device is arranged to be of the latticed structure composed of the upper cover plate, the lower cover plate and the supporting plate, the supporting plate is obliquely arranged, on one hand, the structural strength of the concave bottom frame device is improved, heavy goods can be conveniently borne by the concave bottom frame device, on the other hand, on the basis that the concave bottom frame device is reinforced, the self weight of the concave bottom frame device is reduced, and the service life of the concave bottom frame device is prolonged. And therefore, the rail is prevented from being damaged due to overlarge stress.

    本发明涉及铁路车辆技术领域,具体而言,涉及一种凹底平车。包括凹底架装置,所述凹底架装置包括上盖板、下盖板以及支撑结构,所述上盖板和所述下盖板沿竖直方向间隔分布,所述支撑结构设置在所述上盖板和所述下盖板之间,所述支撑结构包括支撑板,所述支撑板相对所述上盖板和/或所述下盖板倾斜设置,且所述支撑板的两端分别和所述上盖板、所述下盖板连接。通过将凹底架装置设置为由上盖板、下盖板以及支撑板之间组成的网格状结构,并将支撑板倾斜设置,一方面提升了凹底架装置的结构强度,便于其对重型货物进行承载,另一方面,其在对凹底架装置加固的基础上,减轻了凹底架装置的自重,进而防止轨道因受力过大而被破坏。
