The invention discloses a hopper car bottom door accidental opening prevention device and a hopper car, and relates to the field of railway wagons. One end of the connecting rod is hinged to one end of the touch plate, a spring seat is arranged on the vehicle end partition plate, and the spring seat is connected with the connecting rod and applies elastic acting force to the connecting rod in the first direction; the lock hook assembly is hinged to the other end of the connecting rod, the lock hook assembly comprises a torsion spring, and the torsion spring can enable the lock hook assembly to rotate towards the bottom door; when the connecting rod moves in the first direction, the lock hook assembly can move in the direction away from the bottom door. The accidental opening prevention device is provided with the rotatable touch plate and the lock hook assembly, when the accidental opening prevention device is different from opening and closing of the bottom door in the working process, the lock hook assembly locks the bottom door after the bottom door is closed in place, the lock hook assembly is opened in advance when the bottom door is opened, opening of the bottom door is not affected, and the safety of the bottom door is improved. Locking and opening effects are achieved through acting force of the spring seat and the torsion spring, and extra operation is not needed.

    本发明公开了一种漏斗车底门防意外开启装置及漏斗车,涉及铁路货车领域,包括:触板,中部铰接在车辆端隔板上;连杆,一端与触板的一端铰接,车辆端隔板上设置有弹簧座,弹簧座与连杆连接,并对连杆沿第一方向施加弹性作用力;锁钩组件,与连杆的另一端铰接,锁钩组件包括扭转弹簧,扭转弹簧能够使锁钩组件向底门方向转动;连杆向第一方向移动时能够使锁钩组件向远离底门方向移动;该防意外开启装置设置有可转动的触板和锁钩组件,在工作过程中与底门的开闭不同时,待底门关闭到位后锁钩组件对底门产生锁闭作用,底门开启时锁钩组件提前打开,不影响底门开启,通过弹簧座和扭转弹簧的作用力实现锁闭和打开作用,无需额外操作。
