The invention discloses an elevator lifting safety device. The elevator lifting safety device comprises an elevator machine room body, a winding steel rope and sliding shaft frames; the elevator machine room body is mounted between the sliding shaft frames; a bottom frame is mounted on the bottom surface of the elevator machine room body; a fixed frame is mounted in the middle position of the bottom frame; sliding groove frames are mounted at the top of the bottom frame and are positioned on two sides of the fixed frame; a driving ejection wheel and a friction wheel are mounted below the sliding groove frames through sliding frames; and ejector rods are mounted on the upper and lower sides of the outer sides of the driving ejection wheel and the friction wheel. The elevator lifting safetydevice has the following beneficial effects that the elevator lifting safety device is simple in structure, and can perform the friction braking with the sliding shaft frames to prevent a sudden dropwhen an elevator is broken down; meanwhile, structures for decelerating and limiting the elevator machine room body are mounted at the bottoms of the shaft frames to avoid accidents after the elevatoris descended; and meanwhile, a device for driving the elevator machine room body to open is provided, so that the device can be opened on a proper floor to facilitate the escape of passengers.

    本发明公开了一种电梯升降安全装置,包括电梯机房体、收卷钢绳和滑动井道架,所述电梯机房体安装在所述滑动井道架之间,所述电梯机房体底面安装有底架,所述底架中间位置安装有固定架,所述底架顶部安装有滑动槽架,所述滑动槽架位于所述固定架两侧,所述滑动槽架下方通过滑动架安装有驱动顶轮和摩擦轮,所述驱动顶轮和所述摩擦轮外侧上下两侧均安装有顶杆。有益效果在于:装置结构简单,能够在电梯出现故障时,通过与滑动井道架进行摩擦制动,进而避免骤降的情况发生,同时井道架底部安装有对电梯机房体进行减速限位的结构,避免在电梯降下后发生意外,同时设置驱动电梯机房体开启的装置,能够在合适的楼层将装置开启,方面乘客逃出。
