The invention relates to the technical field of rail transportation, in particular to a rail-replaceable stone ballast hopper car underframe which comprises a pair of side beam assemblies arranged inparallel, end beam assemblies are arranged at the two ends of the side beam assemblies, the end beam assemblies are inwards connected with traction beam assemblies, and the two traction beam assemblies are connected through a middle beam assembly. A narrow gauge side bearing suitable for a narrow gauge and a standard gauge side bearing suitable for a standard gauge are arranged on the lower portions of the traction beam assemblies. By arranging the side beam assemblies, the end beam assemblies, the traction beam assemblies and the middle beam assembly, a stable and reliable frame structure isobtained, the self weight can be reduced under the condition that the strength requirement is met, and energy consumption in the operation process is reduced; and meanwhile, the narrow gauge side bearing and the standard gauge side bearing are arranged below the traction beam assemblies, so that the underframe can be simultaneously suitable for various rails and is more flexible and convenient inthe actual use process.
本发明涉及轨道运输技术领域,具体涉及一种可换轨的石砟漏斗车底架,包括一对平行设置的侧梁组成,侧梁组成的两端均设置有端梁组成,端梁组成向内连接牵引梁组成,两个牵引梁组成通过中梁组成连接;所述的牵引梁组成的下部设置有适用于窄轨的窄轨旁承和适用于准轨的准轨旁承。本发明通过设置侧梁组成、端梁组成、牵引梁组成和中梁组成得到了稳定可靠的框架结构,能够在满足强度需求的情况下减轻自身的自重,节省运行过程中的能源消耗;同时在牵引梁组成的下方设置窄轨旁承和准轨旁承,可以同时适用于多种轨道,在实际使用过程中更加灵活方便。
