Abstract
The utility model discloses an elevator safety protection device comprising a top impacting prevention device at the top end of an elevator upright and an anti-falling device at the top of an elevator car body. The elevator safety protection device can cut off a control power supply before top impacting of an elevator, and quickly brake the elevator when the elevator falls to prevent a fall accident. A travel switch contact point is connected in series with a control power cord of a windlass, so that when the elevator is out of control due to electric reasons and the elevator car body rises to a limit height, the elevator car body triggers a travel switch to act to cut off the control power supply of the windlass, and the elevator car body stops moving due to mechanical brake of the windlass, thus preventing top impacting; and mechanical elastic brakes are mounted on the main beam of the elevator car body, when the elevator car body losses a lifting force, the tension of a lifting wire cable serves as an action signal of the mechanical elastic brakes, the elastic forces of springs push pin rods to perform rectilinear motion, and the pin rods are inserted between cross beams of uprights to brake the elevator car body so as to prevent the elevator car body from falling.
