Abstract
The utility model discloses a safe falling protector which comprises a speed limiter, a pressure spring, a pressure spring seat, a closed steel wire rope, a first pulley, a counterweight, a transmission mechanism, a trigger mechanism, a tension spring and safe pliers. The counterweight is fixed onto a first pulley shaft, the closed steel wire rope penetrates through the pressure spring, and then is sequentially wound around the speed limiter and the first pulley to form a closed rope ring, the closed rope ring moves up and down along with a lift car, the pressure spring seat is fixed onto the closed steel wire rope, and the pressure spring is arranged between the pressure spring seat and the lift car. When the lift car falls in a speed loss manner, the speed limiter triggers the trigger mechanism to act via the transmission mechanism, the trigger mechanism is connected with the speed limiter, accordingly, a switch for constraining action of the safe pliers is removed, and the tension spring pulls the safe pliers to clamp guide rails of the lift car. By the aid of the safe falling protector, the lift car (a cage) which falls down in the speed loss manner can be clamped on the guide rails, falling safety accidents are effectively prevented, and personal safety of people is guaranteed. The safe falling protector with excellent performance is widely applied to the construction industry.
