The invention discloses an elevator speed limiter which comprises a mounting base, a front mounting frame and a rear mounting frame are arranged on the mounting base, an extension spring and a spring box are mounted on the rear mounting frame, an electromagnetic valve is further connected to the rear mounting frame, and a speed limiter wheel is arranged between the front mounting frame and the rear mounting frame. A shock absorber and a brake are further arranged between the front mounting frame and the rear mounting frame, the shock absorber is fixedly connected to the brake through a pin, a lower connector of the shock absorber abuts against the speed governor wheel, a cleaning assembly is further arranged on the mounting base and used for cleaning the interior of a rope groove of the speed governor wheel, and the cleaning assembly comprises a cleaning frame, a driven wheel and a brush plate assembly. A scraper extending into the rope groove is arranged on one side of the cleaning frame in an upward extending mode, the driven wheel is matched with the speed limiter wheel, and the brush plate assembly is provided with bristles extending into the rope groove. Vibration impact of a speed governor wheel can be effectively absorbed, the damping effect of the speed governor is improved, meanwhile, a rope groove of the speed governor is cleaned, and the accident that a safety protection switch of the speed governor is triggered or a rope is derailed and falls off due to excessive accumulation of oil dirt is avoided.

    本发明公开了一种电梯限速器,包括安装底座,安装底座上设置有安装前架和安装后架,所述安装后架上安装有拉伸弹簧和弹簧盒,所述安装后架上还连接着电磁阀,安装前架与安装后架之间设有限速器轮,所述安装前架与安装后架之间还设有减震器和制动器,所述减震器由销钉固连在制动器上,所述减震器的下接头抵在限速器轮上,所述安装底座上还设有清理组件,用于对限速器轮的绳槽内部进行清理,包括清理架、从动轮和刷板组件,所述清理架的一侧向上延伸设置有伸入到绳槽内的刮刀,所述从动轮与限速器轮配合,所述刷板组件设有伸入到绳槽的刷毛。本发明能够有效地吸收限速器轮的震动冲击,提高了限速器的减震效果,同时对限速器绳槽进行清理,避免油污过度堆积触发限速器的安全保护开关或者导致绳索出轨脱落事故。
