The invention discloses an emergency braking device for an elevator car, and relates to the technical field of elevators. Comprising a brake and a hydraulic system, a mounting seat of the brake is fixed on a car frame, an elevator car is mounted on the car frame, the car frame moves up and down in a hoistway along an elevator guide rail, two brake calipers of the brake are located on the two sides of the elevator guide rail, and when the elevator runs in an overspeed mode or has the top and bottom rushing danger, the brake calipers of the brake can brake the elevator. And the hydraulic system controls the two brake calipers to extend out so as to clamp the elevator guide rail, so that the elevator car is stopped on the elevator guide rail. The braking devices are installed on the two sides of the car frame and act on the left row of elevator guide rails and the right row of elevator guide rails correspondingly, so that a firm protective barrier for guaranteeing safety of personnel and equipment is established, the braking devices act when overspeed occurs, the elevator car is stopped on the elevator guide rails before rushing to the top or squatting to the bottom, accidents are effectively prevented, and the safety of the elevator is improved. And the safety of elevator taking personnel and equipment is protected to the greatest extent.
本发明公开了一种电梯轿厢紧急制动装置,涉及电梯技术领域。包括制动器和液压系统,所述制动器的安装座固定于轿厢架上,电梯轿厢安装于所述轿厢架上,所述轿厢架沿电梯导轨在井道内上下运动,所述制动器的两个制动钳位于所述电梯导轨的两侧,当电梯出现超速运行或有冲顶蹲底危险时,液压系统控制两个所述制动钳伸出从而夹紧电梯导轨,使得电梯轿厢制停在电梯导轨上。本发明的制动装置安装在轿厢架两侧,分别作用于左右两列电梯导轨上,从而建立起保障人员和设备安全的一道坚固的防护屏障,当出现超速时制动装置将动作,使电梯轿厢在冲顶或蹲底之前制停在电梯导轨上,有效防止事故的产生,最大程度的保护乘梯人员和设备安全。
