The invention discloses a modular assembly lower side door which comprises a door frame, a lower side door body installed on the door frame and a pair of hinges arranged in parallel, the top end of each hinge is hinged to the top of the door frame through a hinge base, and the bottom end of each hinge is locked to the lower portion of the door frame through a hasp; the lower side door body comprises a door plate, the outer surface of the middle of the door plate is recessed inwards to form a protrusion, and an inward door plate groove is formed in the periphery of the recess to form a door plate boss. An outward door frame groove is formed in the inner surface of the door frame and located on the periphery of the door opening, and the door frame groove is matched with the door plate boss. All the parts are modularly formed, so that the lower side door of an existing railway open wagon can be rapidly and integrally replaced, and meanwhile, the lower side door of a newly-manufactured railway open wagon can be assembled; meanwhile, compared with an existing open wagon lower side door, the modular assembly lower side door is higher in structural strength, more resistant to corrosion and better in sealing performance, the maintenance cost of the railway open wagon lower side door can be effectively reduced, and meanwhile the vehicle utilization rate is increased.
本发明公开了一种模块化组装下侧门,包括门框、安装在门框上的下侧门本体及一对平行布置的折页,每个折页的顶端通过折页座铰接在门框的顶部,折页的底端通过搭扣与门框的下部锁闭;所述下侧门本体包括门板,门板的中间部位外表面向内凹陷形成凸起,凹陷的周边处有向内的门板凹槽形成门板凸台;所述门框的内表面且位于门洞周边处有向外的门框凹槽,且门框凹槽与门板凸台相配合。各个部件模块化成型,能实现铁路现有敞车快速整体更换下侧门,同时可以实现新造铁路敞车下侧门的组装;同时较现有敞车下侧门,其结构强度更强、更耐腐蚀且密封性能更好,可有效降低铁路敞车下侧门的维修成本,同时提高车辆利用率。
