Description

Auxiliary stay stair safety device

Technical Field

The invention relates to the technical field of renewable energy utilization, in particular to auxiliary support stair safety equipment.

Background

In the current modern war, along with the application of high-tech weapons in land and sea battlefields, the destruction efficiency of the weapons is increased, the probability of group death group injury caused by air attack, accurate guided 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 a climbing vehicle, an aerial ladder vehicle and other rescue machines, are all devices for high-altitude accident rescue. When the aerial work platform is used, the aerial work or trapped personnel climb to the ground through the aerial ladder stool. However, the number of people carried by the aerial ladder stool is limited, and the high-altitude operation personnel or the trapped personnel need to crawl on the aerial ladder stool, so that the time between two rescues is very long, the high-altitude operation personnel or the trapped personnel cannot be quickly sent to the ground, and the rescue efficiency is very 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.

When disasters happen to general floors, most of the disasters can escape from the stairs, the stairs easily collapse due to violent vibration or overweight, the collapsed stairs are used as main escape tools, the collapsed stairs are fatal, the escape can be continued after the collapse of the stairs, and the life safety of escape personnel needs to be guaranteed by considering the improvement of the stairs. Therefore, how to shorten the time between two rescue works, improve or create a new stair or stair safety device, and design a new rescue device or device to improve the rescue efficiency is a technical problem that needs to be solved by those skilled in the art at present.
