[0002] Due to the dense population in high-rise buildings, in case of a fire, evacuating people safely through traditional safety channels, such as fire-fighting passages, safety cabins, or helicopter rescue on the top floor, it is very difficult to evacuate all people safely in a short time. And because of the high floors, it is also very difficult to deploy fire ladders, often missing the best rescue time and causing heavy losses of personnel and property. For firefighters to fight fires, it is impossible to enter high floors to fight fires due to the high temperature and thick smoke of the flames on the floors eroded by the fire. At present, climbing devices can be used for high-rise fire fighting and rescue. For example, patent CN 202310151495.7 discloses a fire fighting and rescue device for high-rise buildings, but the structure of this rescue device is too complex and the manufacturing cost is high, which is not conducive to popularization.
