At the same time, the speed sensor 32 detects the running speed of the elevator in real time and transmits the signal to the elevator speed limiter controller 31 of the speed limiter. Then, when the running speed of the elevator exceeds the preset safe speed range, the elevator speed limiter controller 31 will drive the elevator speed limiter control arm 33 to move, so that the elevator speed limiter speed limiting wheel 34 presses the elevator rope. This pressing action will generate friction, slow down the movement speed of the elevator rope, thereby reducing the running speed of the elevator. Finally, the elevator speed limiter outer protective frame 4, the protective frame outer fixed plate 5 and other components provide additional safety protection to ensure that the speed limiter as a whole can function reliably when an abnormal situation occurs in the elevator.
