Ratchet wheel-escapement composite structure type high-altitude descent control device

The ratchet wheel-escapement composite structure type high-altitude descent control device comprises a descent control device shell, and the interior of the descent control device shell is divided into a descent control cavity, a rope guide cavity and an emergency locking cavity through two partition plates; the rotating shaft can rotate at a constant speed through the escapement type slow descending mechanism, so that the guide wheel assembly enables the safety rope to descend at a constant speed under the action of friction force of the safety rope, and when the descending speed is suddenly increased in the descending process, the emergency locking mechanism can lock the rotating shaft, so that the rotating shaft stops rotating; the safety of the high-altitude descent control device is further improved, and the situation that people are dangerous in emergency is avoided. 本发明公开了一种棘轮-擒纵复合结构式高空缓降器，包括缓降器壳体，所述缓降器壳体的内部经两个分隔板分为缓降腔、导绳腔和紧急锁死腔；本发明通过设有的擒纵式缓降机构可以使得旋转轴匀速转动，从而使得导轮组件在安全绳的摩擦力作用下使得安全绳匀速下放，当下降过程中下降速度突然加快后，紧急
