The invention relates to the technical field of railway wagons, and discloses a bottom door opening and closing device capable of being opened and closed manually and a hopper car, the bottom door opening and closing device comprises a connecting rod mechanism, two sides of a transmission plate at the output end of the connecting rod mechanism are rotatably connected with transmission rods, and the ends of the transmission rods are rotatably connected with bottom door assemblies; the spiral transmission mechanism comprises a threaded pipe and a threaded rod which are in threaded fit, the threaded pipe is matched with the rotary supporting mechanism, one end of the threaded pipe is connected with a hand wheel to achieve rotation, one end of the threaded rod is connected with the input end of the connecting rod mechanism through a first connecting plate, and a transmission plate of the connecting rod mechanism drives the transmission rod to reciprocate to pass through the dead point position to manually open and close the bottom door assembly. Manual opening and closing of the bottom door assembly are achieved through cooperation of the hand wheel and the spiral transmission mechanism and the connecting rod mechanism, self-locking of the bottom door is achieved by controlling the transmission rod to cross the dead point position through the hand wheel, the structure is simple, the overall structure is a mechanical structure, and the failure rate is low; and the spiral transmission mechanism can realize mechanism self-locking, so that the safety is ensured.
本发明涉及铁路货车技术领域,公开了一种可手动启闭的底门开闭装置及漏斗车,包括:连杆机构,其输出端的传动板两侧转动连接传动杆,传动杆端部转动连接底门组件;螺旋传动机构包括螺纹配合的螺纹管和螺纹杆,螺纹管与转动支撑机构配合,且一端连接手轮实现转动,螺纹杆一端通过第一连接板连接连杆机构的输入端,通过连杆机构的传动板带动传动杆往复经过死点位置以对底门组件手动启闭;通过手轮、螺旋传动机构配合连杆机构实现底门组件的手动启闭,通过手轮控制传动杆越过死点位置实现底门的自锁,结构简单,且整体结构为机械结构,故障率低;螺旋传动机构可实现机构自锁,保证安全性。
