The invention relates to a two-stage braking high-stability elevator speed limiter which comprises a bottom plate, a machine shell arranged on the bottom plate and a rope sheave mechanism arranged inthe machine shell. The rope sheave mechanism comprises a rope sheave and two sets of centrifugal triggering mechanisms installed on the rope sheave, the two sets of centrifugal triggering mechanisms are symmetrically arranged on the two sides of the rope sheave, the centrifugal triggering mechanism on one side is connected with an electrical control mechanism for electrical braking control, and the centrifugal triggering mechanism on the other side is connected with a mechanical control mechanism for mechanical braking control. Compared with the prior art, the centrifugal triggering mechanismsare symmetrically arranged on the two sides of the rope sheave, electric appliance action triggering and mechanical action triggering are separated, a certain control priority level is set, and the stability and reliability of the control speed are greatly improved.

    本发明涉及一种两级制动的高稳定性电梯限速器,包括底板、设于底板上的机壳以及设于机壳内的绳轮机构,所述绳轮机构包括绳轮以及安装于绳轮上的离心触发机构,所述离心触发机构设有两组,对称设于所述绳轮的两侧,其中一侧的离心触发机构与电气控制机构连接进行电气制动控制,另一侧的离心触发机构与机械控制机构连接进行机械制动控制。与现有技术相比,本发明离心触发机构对称设于绳轮的两侧,电器动作触发和机械动作触发实现分离,并设置一定控制优先级别,大大提高控制速度的稳定性和可靠性。
