In an embodiment of the present invention, centrifugal action mechanism can with but not only three-link mechanism, three-link mechanism it is logical
It crosses tension spring to connect with the second rotating wheel, when the velocity of rotation of the second rotating wheel is faster, block distance is got rid of by centrifugal action mechanism
The distance of the center of rotation of two rotating wheels is remoter, after the velocity of rotation of the second rotating wheel, which reaches, limits speed, gets rid of block triggering machine
Tool trigger mechanism, elevator brake.
First driving wheel will not be rotated when express elevator runs well, when express elevator speed has been more than limiter of speed
Speed limit when, centrifugal action mechanism is increased by centrifugal force, gets rid of block and move to far from the direction of center of rotation, and then drive first
Rotating wheel follows centrifugal action mechanism to rotate together, specifically, either friction can be passed through by the way that block is arranged in mating surface
To drive the rotation of the first rotating wheel, the first block on the first driving wheel that stretching end motion, external part is pushed to drive the second fixture block
Rotation, at this point, the reduction of the distance between the second fixture block and the first fixture block, the rope of safety tongs is from the first fixture block and the second fixture block
