The invention relates to an electric braking mechanism of speed limiter used for a high-speed elevator. The electric braking mechanism comprises a centrifugal triggering assembly and an electric control connecting rod assembly which are arranged on a speed limiter rope sheave, wherein the electric control connecting rod assembly comprises an electric appliance triggering rod and an electric switchtouch rod, the electric appliance triggering rod is hinged to a machine shell of the speed limiter through a first hinge point, the upper end of the electric appliance triggering rod makes contact with the centrifugal triggering assembly, the lower end of the electric appliance triggering rod presses one end of the electric switch touch rod, an electric switch is arranged on the upper portion ofone end of the electric switch touch rod, the electric switch touch rod is hinged to the machine shell through a second hinge point, the second hinge point divides the electric switch touch rod into along end and a short end, and the end, close to the electric switch, of the electric switch touch rod is shorter. Compared with the prior art, the electric appliance control mechanism adopts the lever principle, and is reliable in action and high in sensitivity.
本发明涉及一种高速电梯用限速器的电气制动机构,包括设置于限速器绳轮的离心触发组件和电气控制连杆组件,所述电气控制连杆组件包括电器触发杆和电气开关触碰杆,所述电器触发杆通过第一铰接点铰接于限速器的机壳上,所述电器触发杆上端与所述离心触发组件接触,下端压在电气开关触碰杆一端,并在电气开关触碰杆一端的上部设置电气开关,所述电气开关触碰杆通过第二铰接点铰接于机壳上,第二铰接点将电气开关触碰杆分成一端长一端短两部分,且靠近电气开关的一端较短。与现有技术相比,本电器控制机构采用杠杆原理,动作可靠、灵敏度较高。
