The invention discloses an anti-falling emergency protection device used in an elevator shaft. The anti-falling emergency protection device comprises the elevator shaft and an elevator car, stop blocks are fixedly installed on the two sides of the top of the elevator car, arc-shaped clamping grooves are formed in the bottoms of the stop blocks, stop plates are fixedly installed outside connecting rods, arc-shaped limiting strips are fixedly installed at the two ends of the top of each stop plate, anti-falling plates are fixedly installed on the two sides of the arc-shaped limiting strips, limiting grooves are formed in the two ends of the stop plates, the outer parts of buffering rods are sleeved with first buffering springs, and a buffering plate is fixedly mounted at the top of a supporting plate. Through arrangement of the stop plates and the stop blocks, when a steel wire rope is broken and the elevator car falls, the elevator car rapidly descends, at the moment, the stop blocks cannot be aligned with the limiting grooves in the stop plates, the stop blocks fall at the tops of the stop plates, along with continuous rotation of a traction machine, the arc-shaped clamping grooves in the bottoms of the stop blocks are completely located outside the arc-shaped limiting strips, under the action of the anti-falling plates, the arc-shaped limiting strips are clamped at the bottoms of the stop blocks, and thus the elevator car cannot continuously descend.
本发明公开了一种用于电梯井内的防坠落紧急保护装置,包括电梯井和轿厢,轿厢顶部的两侧均固定安装有截止块,截止块的底部开设有弧形卡槽,连杆的外部固定安装有截止板,截止板顶部的两端均固定安装有弧形限位条,弧形限位条的两侧均固定安装有防落板,截止板的两端均开设有限制槽,缓冲杆的外部套接有第一缓冲弹簧,支撑板的顶部固定安装有缓冲板。通过设置截止板和截止块,当钢丝绳断裂使轿厢坠落时,轿厢快速下降,此时的截止块未能与截止板中的限制槽对位,截止块便落在了截止板的顶部,随着曳引机的继续转动,截止块底部的弧形卡槽便完全位于弧形限位条的外部,由于防落板的作用,弧形限位条卡在截止块的底部,使轿厢无法继续下降。
