The invention discloses an elevator safety protection system. The elevator safety protection system is characterized in that the elevator safety protection system comprises a slip monitoring device, wherein the slip monitoring device comprises a differential slow release module, a differential belt module, a synchronous access module and two elastic tensioning modules, a friction wheel is rotatably installed on a lift car and closely attached to a guide rail of an elevator shaft, and the friction wheel is linked to a sliding shaft; the differential slow release module comprises a slow releasesliding bracket, an inner wheel, an outer wheel and a plurality of slow release assemblies, the slow release sliding bracket is slidably installed on the lift car, a sliding bracket compressed springfor ejecting the slow release sliding bracket upwards is arranged on the lift car, the inner wheel and the outer wheel are coaxially arranged, and are correspondingly and rotatably installed on the sliding bracket, and thus the inner wheel and the outer wheel can rotate relatively. According to the elevator safety protection system, the slip monitoring device is arranged, when the friction wheel encounters an oil stained area on the guide rail of the elevator shaft, the friction wheel can slip, resulting in the speed difference between the outer wheel and the inner wheel suddenly, and thus therapid detection is facilitated.
本发明公开了一种电梯安全保护系统,其特征在于:包括打滑监测装置,打滑监测装置包括差速缓释模块、差速皮带模块、同步接入模块以及两个弹性张紧模块,摩擦轮转动安装于轿厢上,且紧贴在梯井导轨上,摩擦轮联动至滑动轴;差速缓释模块包括缓释滑动支架、内轮、外轮以及若干缓释组件,缓释滑动支架滑动安装于轿厢上,轿厢上设置有用于向上顶住缓释滑动支架的滑动支架压簧,内轮、外轮同轴设置且分别转动安装于滑动支架上,使得内轮、外轮可以相对转动。本发明通过打滑监测装置在摩擦轮遇到梯井导轨上的有油渍的区域时,摩擦轮会产生打滑,造成外轮和内轮突然之间转速差,从而便于进行快速检测。
