The invention discloses an elevator anti-falling safety catcher. The elevator anti-falling safety catcher comprises a first housing and a second housing, a first shaft hole is formed in the first housing, a second shaft hole is formed in the second housing. The elevator anti-falling safety catcher is characterized in that a main shaft is arranged between the first shaft hole and the second shaft hole, a driving wheel and a driven wheel are arranged on the main shaft, a centrifugal driving assembly and a driven wheel limiting piece are arranged between the driving wheel and the driven wheel, the main shaft penetrates through the centrifugal driving assembly and the driven wheel limiting piece, the driven wheel limiting piece is fixedly connected with the driven wheel, and the centrifugal driving assembly drives the driven wheel limiting piece. According to the safety catcher, a pure mechanical structure is adopted, the centrifugal force principle is utilized, the influence of an external power source is avoided, the effective braking distance is short (25-30 cm), overhauling and replacing are convenient, and the cost is greatly saved.

    本发明公开了一种电梯防坠落速差器,包含一第一罩壳和一第二罩壳,所述的第一罩壳上设有一第一轴孔,所述的第二罩壳上设有一第二轴孔,其特征在于:所述的第一轴孔与第二轴孔之间设有一主轴,所述的主轴上设有一主动轮和一从动轮,所述的主动轮与从动轮之间设有一离心驱动组件和一从动轮限位片,所述的主轴贯穿所述的离心驱动组件和从动轮限位片,所述的从动轮限位片与所述的从动轮固定连接,所述的离心驱动组件驱动所述的从动轮限位片。本发明采用纯机械式结构,利用离心力原理,实现了不受外部电源影响,有效制动距离短(25‑30cm),检修更换方便,大大节约了成本。
