Abstract
A tensioning anti-bouncing mechanism of a compensation rope sheave of a high-speed lift comprises a rail, a steel rope sheave assembly and a stopping device. The steel rope sheave assembly can slide up and down along the rail and is provided with a locating portion. The stopping device is arranged on the rail and comprises a stopping piece. The stopping piece can move between the first position where the stopping piece is close to the rail and the second position where the stopping piece is far away from the rail. When the steel rope sheave assembly slides upwards, a sheave box forces the stopping piece to move to the second position; and when the steel rope sheave assembly goes beyond a critical position, the stopping piece operates from the second position to the first position, so that a protruding portion of the stopping piece is made to be in contact with the locating portion of the sheave box, and therefore the steel rope sheave assembly is limited from falling downwards at a high speed. In this way, the situation that safety problems of passengers in a lift car are caused when the lift car is in emergency brake is avoided.
