Abstract
The utility model discloses a mechanical safety device for preventing overspeed in descending of an escalator or moving sidewalk. The technical scheme includes that a driving wheel drives the escalator or moving sidewalk to run normally, a mounting plate or a weight is pressed on a first limiter by elastic restoring force of an elastic part and separated from a safety switch, a stopper separated from the rotation path of the mounting plate or weight rotating along a rotating plate fails in function of stopping, and accordingly, normal rotation of a brake disc and the driving wheel is guaranteed and power is transmitted. At the moment, the mechanical safety device is at an overspeed working state, the mounting plate or weight is pressed on a second limiter and simultaneously triggers the safety switch to send signals for cutting off a power source, the stopper stops on the rotation path of the mounting plate or weight rotating along the rotating plate and stops the mounting plate or weight, namely stops the rotating plate and the driving wheel, so that the escalator or moving sidewalk can stop in time, and safety accidents are avoided.
