The invention discloses an elevator pit safety protection device, and relates to the technical field of protection devices. The elevator pit safety protection device comprises a first protection plate, two hydraulic oil cylinders are arranged on the lower surface of the first protection plate, the telescopic ends of the two hydraulic oil cylinders are fixedly connected to the upper surface of the first protection plate, and the two hydraulic oil cylinders are correspondingly arranged front and back; two limiting columns which are correspondingly arranged left and right are fixedly connected to the lower surface of the first protection plate, circular plates are fixedly connected to the lower surfaces of the two limiting columns, and by arranging the three protection devices, triple buffering can be conducted on sudden descending of the lift car, so that the overall damping effect is better, the buffering distance is prolonged in a short area, and the service life of the lift car is prolonged. And the situation that when the elevator suddenly falls down, large impact is generated on the protection support, even breakage of the support is possibly caused, and therefore the protection effect cannot be achieved is avoided, and the working safety of workers is improved.
本发明公开了一种电梯底坑安全防护装置,涉及防护装置技术领域。该电梯底坑安全防护装置,包括第一防护板,所述第一防护板下表面设置有两个液压油缸,两个液压油缸的伸缩端均固定连接在第一防护板的上表面上,两个液压油缸为前后对应设置,所述第一防护板的下表面固定连接有两个左右对应设置的限位柱,两个限位柱的下表面均固定连接有圆形板,通过设置三个防护装置,可以对轿厢突发下降进行三重缓冲,使得整体的减震效果更好,在短区域内延长了缓冲距离,避免当电梯突然坠下时,会对保护支架产生较大的冲击,甚至有可能造成支架的断裂,从而起不到保护的作用,提高工作人员的工作安全性。
