The invention provides a locking device of a bottom door opening and closing mechanism of a railroad hopper car, and the bottom door opening and closing mechanism comprises an upper transmission shaft which drives the opening and closing of a bottom door through rotation. According to the device, one end of a transmission mechanism is arranged on the outer side of the side wall of the hopper car, and a check block is arranged at the other end of the transmission mechanism; the upper transmission shaft is provided with a limiting piece with a fixed position, when the transmission mechanism is rotated to enable the stop block to interfere with the limiting piece, the upper transmission shaft cannot rotate, and a locking state of the bottom door opening and closing mechanism is formed; when the transmission mechanism is rotated to enable the stop block to be away from the limiting piece, the upper transmission shaft can rotate, and an unlocking state of the bottom door opening and closing mechanism is formed. According to the technical scheme, the hopper car bottom door opening and closing mechanism has the beneficial effects that a handle of the transmission mechanism only needs to be rotated outside a compartment so that the stop block can interfere with the limiting piece on the upper transmission shaft for driving the bottom door to be opened and closed, the locking or unlocking state of the hopper car bottom door opening and closing mechanism is formed, and workers can directly operate outside the compartment without getting on the hopper car; and the unloading efficiency is improved.

    本发明提供一种铁路漏斗车底门开闭机构的锁闭装置,底门开闭结构包括上部传动轴,通过转动驱动底门的开闭。该装置包括:传动机构的一端设置在漏斗车侧墙的外侧,传动机构的另一端设置有挡块;上部传动轴设有位置固定的限位件,转动传动机构使挡块与限位件相干涉时,上部传动轴无法转动,形成底门开闭机构的锁闭状态;转动传动机构使挡块远离限位件时,上部传动轴能够转动,形成底门开闭机构的解锁状态。本发明的技术方案的有益效果在于,只需在车厢外转动传动机构的手柄使挡块能够与驱动底门开闭的上部传动轴上的限位件互相干涉,形成漏斗车底门开闭机构的锁闭或解锁状态,实现工作人员不上车直接在车厢外进行操作,提高了卸车效率。
