The bogie frame is light in weight, simple and reasonable in structure and comprehensive in function, can meet the requirements of a common bogie frame and the installation requirements of various railway track detection devices, and is an innovation of a bogie frame form. However, the framework of the invention still adopts a conventional concave beam structure, the height of a beam body is not improved, and the problem of small vertical motion enveloping space of the framework still exists when flaw detection equipment is arranged on the framework.
