Abstract
The invention discloses a safety falling protector. The safety falling protector comprises a speed limiter, a pressure spring, a pressure spring seat, a closed steel wire rope, a first pulley and a heavy punch fixed on a first pulley shaft, wherein the closed steel wire rope passes through the pressure spring and bypasses the speed limiter and the first pulley to form a closed rope ring, the closed rope ring moves up and down along with an elevator cage, the pressure spring seat is fixed on the closed steel wire rope, and the pressure spring is arranged between the pressure spring seat and the elevator cage. The safety falling protector is also provided with a transmission mechanism, a trigger mechanism, a tension spring and a pair of safety tongs. When the elevator cage drops with the speed out of control, the speed limiter triggers the trigger mechanism connected with the speed limiter to move by the transmission mechanism, so that a switch for inhibiting the movement of the safety tongs is released, and the tension spring pulls the safety tongs to clamp a guide rail of the elevator cage. According to the safety falling protector, the elevator cage (a hoisting cage) dropping with the speed out of control is clamped on the guide rail, so that the safety accident of falling can be prevented effectively, and the personal safety of people can be guaranteed. The safety falling protector has good performances and is widely applied to the building industry.
