The invention discloses an elevator shaft falling prevention device. The elevator shaft falling prevention device comprises an elevator shaft, an elevator is installed in the elevator shaft, falling prevention plate cavities are symmetrically formed in the front side and the rear side of the elevator shaft in a communicating mode, a falling prevention assembly is arranged in each falling prevention plate cavity, each falling prevention assembly comprises an elevator door sliding groove located in the left side of the elevator shaft, two floor elevator doors which are opened in a sliding mode towards the front side and the rear side are arranged in each elevator door sliding groove in a sliding mode, and an falling prevention box which is connected with the lower end wall of the corresponding falling prevention plate cavity through a gravity spring, is close to the elevator shaft side and communicates with the elevator shaft is arranged in each falling prevention plate cavity in a sliding mode. When the elevator does not reach a corresponding floor and an elevator door in the floor is automatically opened, a falling prevention plate is driven to rotate upwards and reversely to a horizontal state to prevent people from falling off, and meanwhile the elevator operates to drive an elevator blocking plate to slide outwards to prevent the elevator from being out of control to fall off.

    本发明公开了一种电梯井防坠落装置,包括电梯井,所述电梯井内安装有电梯,所述电梯井前后两侧对称连通设有防坠板腔,所述防坠板腔内设有防坠组件,所述防坠组件包括位于所述电梯井左侧的电梯门滑动槽,所述电梯门滑动槽内滑动设有向前后两侧滑动打开的两个楼层电梯门,所述防坠板腔内滑动设有与所述防坠板腔下端壁通过重力弹簧连接且靠近所述电梯井侧与所述电梯井相通的防坠箱,当电梯未达到相应楼层而楼层内的电梯门自动打开时带动防坠板向上反转至水平状态,防止人员失足坠落,同时电梯运转带动电梯阻挡板向外滑动,防止电梯失控坠落。
