| Zusammenfassung: | The invention relates to a novel elevator overspeed protection device, comprising a car guide rail, a safe friction block and a triggering component. The triggering component comprises a rotating rod, a first connecting rod, a second connecting rod and a drive rod. Two ends of the rotating rod are movably connected with the car guide rail, and the drive rod is fixedly connected with one end of the rotating rod. The upper end of the drive rod is connected with the rope of a speed governor. The novel elevator overspeed protection device has the advantage that, the device adopts the safe friction block to replace safety tongs, and the car stops moving due to the effect of the friction force. Overspeed protection is performed. According to the novel elevator overspeed protection device, the structure is further simplified, and the installation is more convenient. |
