The invention discloses an elevator anti-falling buffer device and an elevator. The elevator anti-falling buffer device comprises a speed limiter arranged on a traction machine, a ratchet and pawl mechanism arranged between an elevator car and a guide rail, and a pneumatic device arranged at the bottom end of the elevator car; and when running speed of elevator reaches or exceeds set limit value,the speed limiter gives an alarm and releases electric signals, the ratchet and pawl mechanism acts, meanwhile, the pneumatic device at the bottom end of the elevator car is opened, and therefore theelevator car can be slowly clamped on the guide rail, and passengers do not have the unpleasant feeling of being stopped immediately. According to the elevator, secondary damage of a spring buffer toa human body is avoided, the situation that a hydraulic buffer does not rebound after being impacted is avoided, and an elevator falling accident is avoided; and the safety of personnel in the elevator is guaranteed through the buffer device, and the multifunctionality of the safe anti-falling elevator is improved.

    本发明公开了一种电梯防坠落缓冲装置以及电梯,包括设置在曳引机上的限速器、设置在电梯轿厢与导轨之间的棘轮棘爪机构、设置在电梯轿厢底端的气动装置,当电梯的运行速度达到或超过设定的极限值时,所述限速器报警并释放电信号,棘轮棘爪机构发生作用,同时在电梯轿厢底端的气动装置打开,从而可以让电梯轿厢缓缓卡在导轨上,使乘客没有立即被停下的不愉快的感觉。这种电梯不仅改变了弹簧缓冲器对人体造成二次伤害和液压缓冲器受到冲击后无回弹作用,还避免电梯坠落事故的发生。通过缓冲装置从而保证了电梯内的人员安全,提高了安全防坠落电梯的多功能性。
