Vertical-lifting elevator anti-falling protection device

The invention relates to the field of elevator equipment manufacturing technology, and particularly relates to a vertical-lifting elevator anti-falling protection device. The reasons of elevator falling mainly lie in the drop or breakage of a steel wire rope, overload operation, speed measurement and limiting device and equipment failure, and the elevator falling rarely happens. In order to overcome the shortcomings of the prior art, the invention provides a vertical-lifting elevator anti-falling protection device independent from the existing safety guarantee system. The device provided by the invention consists of a brake box embedded into a shaft wall and a fixing rack fixed on the side surface of a car. When an elevator falls, a brake instruction is given manually or by a speed sensor, an electromagnet in the brake box adsorbs a movable slider so that the teeth of the movable slider are meshed with the teeth of the fixing rack, the teeth of the fixing rack collide with the teeth of the movable slider repeatedly, and the impact force of the falling car is absorbed by a spring set; and when the kinetic energy is completely absorbed and the speed approaches to zero, the resistance against the brake box is greater than the total gravity of the car, thus a soft landing process of the car is formed to realize the brake of the car.
