The invention relates to an elevator car safety protection device. The elevator car safety protection device comprises an upper safety protection device arranged at the top of a car and a lower safety protection device arranged at the bottom of the car, the upper safety protection device comprises a fixing frame fixedly connected with the car, a rolling shaft is fixedly installed on the fixing frame, an elastic adjusting device is arranged on the rolling shaft, a rotatable roller is further installed on the rolling shaft, the elastic adjusting device is sleeved with the roller, and the roller is abutted with the inner wall of an elevator shaft in a rolling mode and is used for elastically adjusting the resistance of the roller to the inner wall according to the speed of the elevator car, and the lower safety protection device comprises an elastic buffer device which is vertically arranged. The roller rolls to be abutted with the wall, the resistance is small during normal operation, the resistance of the roller to the wall is increased when an elevator falls off due to abnormal speed, so that the descending trend is slowed down, and the elastic buffer device at the bottom is impacted to further provide buffering; and the elevator car safety protection device with the structure has a buffering function and is high in safety.
本发明涉及一种电梯轿厢安全保护装置,包括设置在轿厢顶部的上安全保护装置及设置在轿厢底部的下安全保护装置,上安全保护装置包括与轿厢固定连接的固定架,固定架上固定安装有滚轴,滚轴上设有弹性调节装置,滚轴上还安装有可转动的滚筒,滚筒套设在弹性调节装置外,滚筒滚动抵接电梯井的内墙,用以根据轿厢速度弹性调节滚筒对内墙的阻力;下安全保护装置包括沿竖直设置的弹性缓冲装置。通过滚筒滚动抵接墙壁,当运行正常时,阻力较小,当电梯速度失常跌落时,滚筒对墙壁阻力变大,从而减缓下降趋势;底部的弹性缓冲装置受到冲击,进一步提供缓冲。这种结构的电梯轿厢安全保护装置,其具有缓冲功能,安全性较高。
