The invention discloses a simple high-altitude escape device capable of working continuously. The simple high-altitude escape device capable of working continuously comprises a platform and two identical friction pair decelerating slow descending mechanisms. Each slow descending mechanism comprises a hanging basket, a steel wire rope, a hand wheel, a nut, a shaft, a spring, a pressing disc, a friction disc, a fixing disc, a bearing seat, a winding drum and a gear, wherein the shaft is installed on the platform through the bearing seat, and the shaft and the winding drum are connected into a whole; the fixing disc, the friction disc, the pressing disc, the spring, the nut and the hand wheel are sequentially installed on the shaft section at one end of the shaft; the fixing disc is in rigid connection with the bearing seat; a revolute pair is formed by the fixing disc and the shaft, and a revolute pair is formed by the friction disc and the shaft; the pressing disc and the shaft are connected through a spline shaft; a thread pair is formed by the nut and the shaft, and the nut is in rigid connection with the hand wheel; the gear is installed on the shaft section at the other end of the shaft; one end of the steel wire rope is fixed to the winding drum, and the other end of the steel wire rope is connected with the hanging basket. The two slow descending mechanisms are engaged through the gears. The simple high-altitude escape device capable of working continuously has the beneficial effects that the descending speed can be controlled, and safety and reliability are achieved; the device can work continuously, and the efficiency is high; the structure is simple, and cost is low; manufacturing, installation and maintenance are convenient.
