The invention discloses an elevator anti-falling safety protection system. The system is characterized by comprising two speed-limiting brake devices disposed on a car, wherein the two speed-limitingbrake devices are connected by a central shaft, the speed-limiting brake devices comprise friction driving modules, speed-limiting triggering modules, and braking modules, the friction driving modulescomprise friction wheels, gear sets I and rotating shafts I, the friction wheels are rotatably mounted on the car, the friction wheels are connected to the rotating shafts I through the gear sets I to realize rotation of the rotating shafts I, the friction wheels are tightly attached to an elevator well guide rail, and the speed-limiting triggering modules comprise clutch sleeves, clutch heads, bevel gears I, bevel gears II, sliding shafts, shaft heads, rotary pull rods, pendulum bobs, sleeve connection bases and the central shaft. The speed-limiting brake devices of the elevator anti-falling safety protection system can quickly control the braking modules to perform braking operation through the speed-limiting triggering modules when a car falling speed is too fast, and the operation speed is high.
