The invention discloses a sleeper beam, a sleeper beam floor structure and a processing method of the sleeper beam and the sleeper beam floor structure. A plurality of sleeper beam modules are welded to form a sleeper beam body, the height size of the middle area is larger than that of the end area, and the middle area is provided with a traction beam connector used for being connected with a traction beam; the sleeper beam body comprises a sleeper beam upper cover plate, a sleeper beam lower cover plate and a sleeper beam rib plate which are arranged at intervals from top to bottom, and the sleeper beam lower cover plate is provided with a bogie traction seat connector and bogie air spring connectors located on the two sides of the bogie traction seat connector. The middle area is provided with the traction beam connector used for being connected with the traction beam, so that the corresponding height of the traction beam can be designed according to the requirement for the bearing capacity of the traction beam, the height of the position of the traction beam connector where the sleeper beam and the traction beam are connected is equal to the section height of the traction beam, and it is guaranteed that the sleeper beam and the traction beam can be reliably welded; the height of other positions of the sleeper beam does not need to be increased along with the traction beam, and then the weight of the sleeper beam can be reduced.
本申请公开了一种枕梁、枕梁地板结构及枕梁、枕梁地板结构的加工方法,包括由多个枕梁模块相焊接形成枕梁本体,其中部区域的高度尺寸大于端部区域的高度尺寸,中部区域设置有用于与牵引梁连接的牵引梁接口;枕梁本体由上至下包括间隔布置的枕梁上盖板、枕梁下盖板以及枕梁筋板,枕梁下盖板上设置有转向架牵引座接口以及位于转向架牵引座接口的两侧的转向架空气弹簧接口。本申请的中部区域具有用于与牵引梁连接的牵引梁接口,使得牵引梁可以根据自身承载能力的需求设计相应的高度,而枕梁与牵引梁连接的牵引梁接口处的高度与牵引梁的断面高度相等,保证二者能够可靠的焊接,枕梁其他位置则不需要跟随牵引梁增加高度,继而可降低枕梁的重量。
