The invention relates to a centrifugal triggering mechanism for a high-speed elevator speed limiter. The centrifugal triggering mechanism comprises a rope sheave and two groups of centrifugal triggering assemblies mounted on the rope sheave, the two groups of centrifugal triggering assemblies are symmetrically arranged on two sides of the rope sheave, and each centrifugal triggering assembly comprises a centrifugal spring, a connecting rod, a first centrifugal mass block and a second centrifugal mass block, wherein one end of the first centrifugal mass block and one end of the second centrifugal mass block are installed on the rope sheave and connected through the connecting rod, one end of the centrifugal spring is connected to the first centrifugal mass block or the second centrifugal mass block, the other end of the centrifugal spring is connected to the rope sheave, and the first centrifugal mass block and the second centrifugal mass block do centrifugal motion when rotating at a high speed along with the rope sheave. Compared with the prior art, the centrifugal triggering assemblies are 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.
本发明涉及一种高速电梯限速器用离心触发机构,包括绳轮和安装于绳轮上的离心触发组件,所述离心触发组件设有两组,对称设于所述绳轮的两侧,所述离心触发组件包括离心弹簧、连接杆、第一离心质量块和第二离心质量块,所述第一离心质量块和第二离心质量块的一端安装在绳轮上,第一离心质量块和第二离心质量块之间通过连接杆连接,所述离心弹簧一端连接于第一离心质量块或第二离心质量块上,另一端连接于绳轮上,所述第一离心质量块和第二离心质量块随绳轮高速转动时发生离心运动。与现有技术相比,离心触发组件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。
