Kinematic diagram for elevator locking

Abstract

A kinematic diagram for locking an elevator, consisting of a cross beam located on one side of the lower frame of the elevator cabin, on which a control axis with a control lever secured thereto is fixed, two locking levers of a rope locking device are fixed at the ends of the control axis, and two shortened levers, connected by means of a flexible connection to levers kinematically connected to the locking levers of a rope locking device located on the small control axes on the other side of the lower frame of the elevator cabin, in such a way that when the control axis rotates due to the control lever being raised in the direction of the upward movement of the cabin, all locking devices are activated at once for the simultaneous clamping of the ropes, and when the control lever is directed in the direction of the downward movement of the cabin, the ropes are simultaneously released in the nodes of the locking devices.
