The invention provides a speed governor assembly, an elevator safety device and an elevator system. The speed governor assembly comprises a rack; the rope wheel is arranged on the rack and can rotate; the centrifugal mechanism is associated with the rope wheel, and the multiple centrifugal components can be unfolded under the action of inertia force related to the rotating speed of the rope wheel; wherein the centrifugal mechanism comprises: a plurality of centrifugal members pivotally fixed to the sheave; and a holding mechanism by which the plurality of centrifugal members are held in a retracted position; wherein the retaining mechanism is configured to retain the plurality of centrifugal members in the retracted position when the sheave speed increases to a first threshold at a speed less than a first acceleration.
本申请提供了一种限速器组件、电梯安全装置和电梯系统。限速器组件包括:机架;安装在所述机架上的可旋转的绳轮;以及与所述绳轮关联的离心机构,所述多个离心构件能够在与所述绳轮转速相关的惯性力的作用下展开;其中,所述离心机构包括:可枢转地固定至所述绳轮的多个离心构件;以及保持机构,所述多个离心构件由所述保持机构保持在收缩位置上;其中,所述保持机构配置成在所述绳轮转速以小于第一加速度增加至第一阈值时仍将所述多个离心构件保持在所述收缩位置。
