The safety protection device for elevator emergency braking relates to the technical field of elevator safety protection and comprises a bottom box, a barrel is mounted on the inner wall of the bottom of the bottom box, a first pressing rod is movably mounted at the top of the barrel in a penetrating mode, and a first lifting plate component is mounted at one end of the first pressing rod; a second spring component is mounted at the top of the first lifting plate component. The second spring component firstly buffers the elevator for the first time, then pressure is continuously applied to the first lifting plate component and the first spring component, the first spring component buffers the elevator for the second time, and when the elevator does not press the second lifting plate component downwards, the movable rod and the second brush component are located in the through hole, so that the through hole can be dredged; and the situation that hydraulic oil cannot pass through the through hole due to impurities attached to the interior of the through hole or the first lifting plate component descends slowly and cannot effectively buffer falling of the elevator due to the fact that the speed of passing through the through hole is slowed is avoided.

    本发明公开了一种电梯紧急制动用安全防护装置,涉及电梯安全防护技术领域,包括底盒,所述底盒的底部内壁安装有筒体,所述筒体的顶部贯穿活动安装有压杆一,所述压杆一的一端安装有升降板部件一,所述升降板部件一的顶部安装有弹簧部件二。本发明弹簧部件二首先对电梯进行第一次缓冲,随后继续对升降板部件一和弹簧部件一施加压力,弹簧部件一第二次对电梯进行缓冲,在电梯没有下压升降板部件二时,活动杆和刷子部件二位于通孔内部,可以对通孔进行疏通,避免通孔内部附着杂质造成液压油无法通过通孔或者通过通孔的速度变慢造成的升降板部件一下降变慢无法对电梯坠落进行有效缓冲。
