The invention discloses a pedal type elevator emergency braking system which comprises an elevator shaft and an elevator car. Guide rails are arranged on the inner wall of the elevator shaft, and guide shoes in sliding fit with the guide rails are arranged on the outer wall of the elevator car; and the pedal type elevator emergency braking system further comprises brakes symmetrically arranged between the outer walls of the two sides of the elevator car and the guide rails, and a pedal type triggering mechanism arranged in the elevator car and used for braking the brakes. Compared with the prior art, under the conditions that a control protection system of an elevator is abnormal or fails, the brakes are abnormal or fail, and a safety gear is abnormal or fails, emergency braking of the elevator in the elevator car can be achieved by manually stepping on a pedal in the elevator car, and the taking safety of the elevator is improved.
本发明公开了一种踏板式电梯紧急制动系统,包括电梯井、电梯轿厢,电梯井内壁设有导轨,电梯轿厢外壁设有与导轨滑动配合的导靴,踏板式电梯紧急制动系统还包括对称设置在电梯轿厢两侧外壁与导轨之间的制动器、设置于电梯轿厢内的用于使制动器制动的脚踏式触发机构。与现有技术相比,本发明可以在电梯自身的控制保护系统异常或失效、制动器异常或失效、安全钳异常或失效的情况下,通过电梯轿厢内部利用人力踩动踏板实现对电梯在轿厢内部的紧急制动,提高了电梯的乘坐安全性。
