The invention relates to the technical field of railway vehicles, and provides a railway low-floor flatcar middle beam and a flatcar body, the railway low-floor flatcar middle beam comprises a middle beam body and two oppositely-arranged traction beams, and the traction beams are provided with inserting positions; at least one part of each of the two end parts of the middle beam body is inserted into the traction beam through the insertion position and is welded and fixed with the traction beam, and a car coupler and/or car coupler buffer mounting position is formed in the traction beam; and the traction beam and the middle beam body are welded to form a concave structure with two high ends and a low middle part. Through the insertion type design of the traction beam and the middle beam body, the traction beam can be conveniently assembled, the effect of preliminarily positioning the traction beam is achieved, welding of the connecting position of the traction beam and the middle beam body is facilitated, and the connecting and manufacturing process of the middle beam is reduced; a concave structure is formed after the traction beam and the middle beam body are welded and fixed, and the technical requirements that the height of a flatcar is 800 mm and the height of a car coupler is 880 mm can be met at the same time.

    本发明涉及铁路车辆技术领域,并提供了一种铁路低地板平车中梁及平车车体,所述铁路低地板平车中梁包括中梁本体和两个相对设置的牵引梁,所述牵引梁具有插接位,所述中梁本体的两端部分别至少有一部分经所述插接位插入所述牵引梁内,并与牵引梁焊接固定,所述牵引梁内形成有车钩和/或车钩缓冲器安装位;牵引梁与所述中梁本体焊接后形成两端高、中间低的凹形结构。通过牵引梁和中梁本体插入式的设计,方便对牵引梁进行装配,起到对牵引梁初步定位的效果,方便对牵引梁和中梁本体的连接处焊接,降低中梁的连接制造工艺;在牵引梁与中梁本体焊接固定后形成凹形结构,能够同时满足平车高度800mm以及车钩高度880mm的技术要求。
