The invention discloses an elevator anti-falling device. The elevator anti-falling device comprises four guide rails fixedly arranged at four corners of an elevator shaft in a rectangular array distribution manner, wherein a lift car is arranged in the center of the array of the four guide rails in an up-down moving manner; a cavity with a forward opening is formed in the lift car; fixed doors aresymmetrically and fixedly connected to the left wall and the right wall of the front side of the cavity separately; and movable doors are arranged at the front sides of the fixed doors in a left-right sliding manner. According to the elevator anti-falling device, suspension shafts and suspension short shafts can be automatically driven to slide into suspension holes, formed in each floor, of theguide rails while the movable doors are opened, and the suspension shafts and the suspension short shafts slide out of the suspension holes when the movable doors are about to be completely closed; and when it is detected that an elevator falls, the lift car is rapidly stopped through a jamming device, the interior of the lift car is stable, after the lift car is stably stopped, the lift car is lifted to the landing door position through a lifting device, the movable doors are opened, the suspension shafts and the suspension short shafts slide into the suspension holes, a reset device is started after a danger is eliminated, the jamming device is reset, and the elevator returns to normal.

    本发明公开的一种电梯防坠落装置,包括矩形阵列分布固定设于电梯井四角的四根导轨,四根所述导轨阵列中心位置上下移动设有轿厢,所述轿厢内设有开口向前的空腔,所述空腔前侧左右壁上相对称的分别固连有固定门,所述固定门前侧左右滑动设有移动门,本发明能够在移动门打开的同时自动驱动悬挂轴和悬挂短轴,滑入导轨在每楼层开设的悬挂孔内,移动门在快完全关闭时悬挂轴和悬挂短轴滑出悬挂孔,在检测到电梯下坠时,通过卡死装置快速的将轿厢停下来,轿厢内的平稳,在轿厢停稳后,通过举升装将轿箱举升至层门位置,移动门打开,悬挂轴和悬挂短轴滑入悬挂孔内,在危险排除后启动复位装置,卡死装置复位,电梯恢复正常。
