<p>Disclosed is a rope braking apparatus for an elevator, which operates, by using cams, lining plates for braking rope of the elevator. In the apparatus, at the moment eccentric cams (36) secured to a camshaft (35) are rotated and pass a top dead center, with a trigger lever (34) preventing rotation of the camshaft (35), a state of waiting an emergency brake signal (that is, a normal running state) is maintained. If an emergency situation takes place, as an actuator (32) actuates the trigger lever (34) and compressed springs (38) are returned to their original state, a second movable plate (14) is moved toward a fixed plate (12) to brake the rope of the elevator. At this time, since reverse rotation prevention means is installed in a driving or driven gear (27, 29), a rotation force applied to the eccentric cams (36) is not transmitted to a motor (23).</p> |
