Background
In the current modern war, along with the application of high-tech weapons in land and sea battlefields, the destruction efficiency of weapons is increased, the probability of group death and group injury caused by air attack, accurate guidance weapons and non-lethal weapons is greatly increased, and the number of critical victims is obviously increased; because the maneuvering terrain of the troops is enlarged, the distance between the wounded and the treatment mechanism is greatly increased, and particularly, in sea area battles, a large number of wounded need to be sent backward in a position along the front edge of the sea, so that a large number of fighters are occupied to influence the fighting capacity, and the front edge is required to provide higher-level medical guarantee. Therefore, it is necessary to design a multifunctional emergency rescue device which can rapidly and safely transfer the wounded in the battle field with minimum manpower, ensure the exertion of the combat power of the army, and can well complete the rescue and carrying tasks in complex environments (especially complex terrains such as mountainous regions, snowfields and the like and severe weather conditions such as rainy days, burning days and the like).
At present, a plurality of devices for high-altitude emergency rescue, such as climbing vehicles, aerial ladder vehicles and other rescue machines, are all devices for high-altitude accident rescue. When the multifunctional aerial work platform is used, high-altitude work or trapped people climb to the ground through the aerial ladder stool. However, the number of people carried by the aerial ladder is limited, and the high-altitude operation personnel or the trapped personnel need to climb on the aerial ladder, so that the time between two rescues is long, the high-altitude operation personnel or the trapped personnel cannot be quickly sent to the ground, and the rescue efficiency is low. Particularly, in case of emergency and a lot of trapped people, due to the long time between two rescue operations, the best time for rescue may be missed, and even more, casualties may occur.
In general rescue, people only go up along stairs from the bottom of a building to approach a disaster site, so that the damage to the people cannot be reduced, and the rescuers can be dragged into dangerous places, thereby further enlarging the number of people in the disaster or the area of the disaster. Therefore, how to shorten the time between two rescue operations, improve or create a new rescue method, and design a new rescue device or equipment to improve the rescue efficiency is a technical problem that needs to be solved by those skilled in the art.
