The invention discloses an elevator anti-falling protection device. The elevator anti-falling protection device comprises a speed sensor, a small storage battery, a charger, a plurality of stand column air bags, an air distributor and an air bag containing bin. An air bag net is additionally arranged outside each stand column air bag. The stand column air bags are made of nylon fabric, and the nets are made of high polymer materials. The stand column air bags are evenly distributed on the periphery of the bottom of an elevator, and the air distributor connected with the stand column air bags on the periphery is installed in the middle of the bottom of the elevator. The stand column air bags are installed in the independent air bag bin. The speed sensor, the small storage battery and the charger are all independently installed on a whole elevator system. When the running speed is higher than a normal running speed, the speed sensor receives information and sends a signal, the storage battery and an electric detonator are started, striking pins are pushed through power of the electric detonator, air-bag sealing sheets are crushed, high-pressure air enters the air distributor through multiple pipes to enter all the stand column air bags, and an air bag group composed of the multiple stand column air bags is formed. The stand column air bags are impacted, pressure limiting valves are opened to discharge air, impacting force is transferred, the stand column air bags are deflated to absorb impacting force generated by impacting, and the elevator stably falls to the ground.
