The invention provides a railway hopper car bottom door opening and closing mechanism and a railway hopper car, and belongs to the technical field of railway wagons, the bottom door opening and closing mechanism comprises a transmission shaft and a clutch limiting assembly, and the transmission shaft is used for being connected with a bottom door and driving the bottom door to be opened and closed through rotation action; the clutch limiting assembly comprises a first limiting component and a second limiting component, when the transmission shaft acts till the bottom door is completely closed, the first limiting component and the second limiting component are connected to limit the transmission shaft to rotate in the door opening direction, and when the transmission shaft conducts door opening action, the first limiting component and the second limiting component are separated. According to the bottom door opening and closing mechanism of the railway hopper car, locking of the transmission shaft after the bottom door is closed is achieved through the clutch limiting assembly, the bottom door can be effectively prevented from being automatically opened in the running process of the car, unlocking can be achieved without extra power and manual operation in the door opening process, the reliability and stability of the bottom door opening and closing mechanism of the railway hopper car are improved, and the service life is prolonged. And the transportation safety of the vehicle is ensured.

    本发明提供一种铁路漏斗车底门开闭机构及铁路漏斗车,属于铁路货车技术领域,底门开闭机构包括传动轴和离合限位组件,传动轴用于连接底门并通过旋转动作带动底门开闭;离合限位组件包括第一限位部件和第二限位部件,传动轴动作至底门完全关闭时第一限位部件与第二限位部件接合以限制传动轴向开门方向旋转,传动轴进行开门动作时第一限位部件与第二限位部件分离。该铁路漏斗车底门开闭机构利用离合限位组件实现了底门关闭后传动轴的锁闭,可有效避免车辆运行过程中底门自动打开,且在开门过程中不需额外施加动力及人工操作实现解锁,提高了铁路漏斗车底门开闭机构的可靠性、稳定性,保障了车辆的运输安全。
