Abstract
The invention discloses a mechanical safety device for preventing overspeed descending of an escalator or a moving sidewalk. When a driving wheel drives the escalator or the moving sidewalk to normally run, a mounting plate or a weighting block is propped against a first limiting block under an elastic restoring force of an elastic piece, the mounting plate or weighting block is separated from a safety switch, an obstructing piece is separated from a path of the mounting plate or weighting block following the rotation of a rotating plate and the obstructing piece has no obstructing function at the moment, thereby ensuring the normal rotation of a braking plate and the driving wheel and transferring the power. If the descending is overspeed, on the basis of an inertia hysteretic principle,the mounting plate follows the weighting block to rotate by overcoming the elastic restoring force of the elastic piece, the mechanical safety device is in an overspeed working state at the moment, the mounting plate or weighting block is propped against a second limiting block, and meanwhile, the safety switch is triggered by the mounting plate or weighting block, a signal is sent by the safety switch, a power supply is cut off, the path of the mounting plate or weighting block following the rotation of the rotating plate is obstructed by the obstructing piece, and the mounting plate or weighting block is stopped by the obstructing piece, namely the rotating plate and the driving wheel are braked, thereby timely stopping the escalator or the moving sidewalk and avoiding the happening of a safety accident.
