Method of production of a braking unit for an elevator

摘要

The invention relates to a design method for the breaking unit. The method mainly includes arranging the guide rail between the first gear and the trolley wheel; arranging for the first gear to engage with the gear surface of the guide rail; arranging for the connecting rod to make the second gear revolve around the axis of the first gear and engage with the first gear, providing each side of the up and down sides of the first gear with a second gear; providing the connecting rod with a triggering bore pluggably matting with the triggering end; when the triggering end withdraw from the triggering bore, arranging for the elastic force to make the second gear engage with the guide rail, at this moment, the mechanism has zero freedom degree, the elevator can not move upward or downward so as to achieve that the elevator brakes when the elevator is in fault state.
