The invention relates to a cage stall protection device. The cage stall protection device comprises a rack, wherein a guide rope freely falls from each of two sides of the rack; two guide wheels whichare arranged front and back and clamp the guide ropes on the corresponding sides are mounted on one side of the rack; a centrifugal releaser is mounted on a rotating shaft of one of the guide wheels;and a catcher which is used for clamping the two guide ropes and is started through the centrifugal releaser is mounted on the rack. The cage stall protection device can brake when the falling speedof a cage exceeds the standard specification requirement, and the cage is decelerated to stop, so that safety accidents caused by out-of-control falling of the cage are avoided, and the operation is safe and reliable.
罐笼失速保护装置,包括机架,在机架两侧分别自由垂落一条导向绳,在机架一侧安装二个前后布置且将对应侧导向绳夹持的导向轮,在其中一导向轮的转轴上安装离心释放器,在机架上安装用于夹持二条导向绳且通过离心释放器启动的抓捕器。其可在罐笼下落速度超出标准规范要求时进行制动,将罐笼减速至停车,避免罐笼因下落失控而发生安全事故,作业安全可靠。
