The invention relates to the technical field of train door opening, in particular to a freight train top rotating type hinged door structure which comprises a train body, and rotating arms are arranged at the two ends, facing the inner side of the train body, of a train door. The driving mechanism comprises mounting frames, driving modules, connecting rods and track grooves, the mounting frames are fixed to the two ends of the vehicle body in the length direction, the driving modules are arranged on the mounting frames, the two ends of the connecting rods are connected with the driving modules and rotating arms correspondingly, and the rotating arms are slidably connected with the track grooves; a support mechanism; a locking mechanism; the driving mechanism is arranged on the vehicle door, the vehicle door is stably and rotationally closed from the top, the supporting mechanism is movably arranged, the supporting effect can be guaranteed when the vehicle door is closed, cargo loading and unloading are not affected when the vehicle door is opened, the locking mechanism is arranged, multi-point locking can be achieved on the whole vehicle door, the door opening and closing process is stable, and the safety is high. The loading space is not affected, the stress is uniform when the vehicle door is closed, the locking effect is good, the limitation of opening and closing the door of a large-length door leaf is broken through, and the practicability is high.
本发明涉及列车开门技术领域,尤其涉及一种货运列车顶部旋转式对开门结构,包括:车体,车门两端朝向车体内侧设有转臂;驱动机构,包括安装架、驱动模组、连杆和轨迹槽,安装架固定在车体长度方向的两端位置处,驱动模组设置在安装架上,连杆两端分别与驱动模组和转臂连接,转臂与轨迹槽滑动连接;支撑机构;锁紧机构;通过在车门上设置驱动机构,将车门从顶部稳定旋转关闭,通过将支撑机构可移动式设置,既能够保证车门关闭时的支撑作用,也不影响车门打开时的货物装卸,通过设置锁紧机构,能够对整体车门实现多点锁紧,开关门过程稳定,且不影响装货空间,车门关闭时受力均匀,锁紧效果好,突破了大长度门扇开关门的限制,实用性较强。
