The invention discloses a full-riveting modular middle beam structure, a flatcar underframe and a railway flatcar. According to the technical scheme, the full-riveting modular middle beam structure comprises traction beam modules and a fish-bellied beam module. The traction beam modules are symmetrically installed at the two ends of the fish-bellied beam module, and the traction beam modules are riveted to the fish-bellied beam module; the fish-bellied beam module adopts a hollow structure so as to reduce the dead weight. A large amount of welding of an existing vehicle chassis and adjustmentand repair and welding fume splashing removal work generated by a welding process can be avoided; meanwhile, problems of long maintenance time and high maintenance cost due to the fact that modular maintenance cannot be carried out in the maintenance process are solved.

    本发明公开了一种全铆接模块化中梁结构、平车底架及铁路平车,其技术方案为:中梁结构包括牵引梁模块和鱼腹梁模块,所述鱼腹梁模块两端对称安装牵引梁模块,且牵引梁模块与鱼腹梁模块铆接;其中,所述鱼腹梁模块采用镂空结构以减轻自重。本发明能够避免现有车辆底架进行大量焊接以及因焊接工艺产生的调修和焊烟飞溅清除工作;同时解决在检修维护过程中无法进行模块化维护、造成检修维护时间长、维护费用高的问题。
