Description

A rapid rescue fire truck

technical field

The invention belongs to the technical field of fire fighting and rescue, and in particular relates to a fast rescue fire truck.

Background technique

Fire trucks, also known as fire trucks, refer to special vehicles that are mainly used to perform fire response tasks. Fire departments in most countries, including China, also use them for other emergency rescue purposes. Fire trucks can transport firefighters to the scene of disasters and provide them with a variety of tools for disaster relief tasks. Modern fire trucks are usually equipped with steel ladders, water guns, portable fire extinguishers, self-contained breathing apparatus, protective clothing, rescue tools, first aid tools and other equipment, and some of them are also equipped with large fire extinguishing equipment such as water tanks, water pumps, and foam fire extinguishing devices. The appearance of fire trucks in most areas is red, but in some areas the appearance of fire trucks is yellow, as are some special fire trucks. The top of fire trucks is usually equipped with alarm bells, sirens, lights and flashing lights. Common types of fire trucks include water tank fire trucks, foam fire trucks, pump fire trucks, climbing platform fire trucks, ladder fire trucks, etc.

At present, aerial ladder fire trucks are mainly used to rescue people in high-rise buildings, with a maximum height of more than 70 meters. However, due to low efficiency, it is very difficult for rescued people to descend from the aerial ladder to the ground. Those who are afraid of heights, old, weak or injured cannot get down, and the aerial ladder truck needs to be recovered. The speed of the ladder is slow, and the efficiency of saving people is very low; in 2009, the State Intellectual Property Office announced a patent for the invention of an escape device for fire trucks. The patent number is 200920171770.7. The way of connection is that the telescopic cylinder replaces the traditional telescopic arm to bear various loads and moments. Since the interior of the telescopic cylinder is designed as an escape channel for personnel, the structure of this method is complicated. In order to accommodate personnel to escape, personnel are left inside the entire telescopic cylinder. Various loads and moments have to be borne through the space, resulting in a huge volume structure, complex structure, and high cost. The traditional vehicle chassis is not suitable. In addition, the water impact deceleration method for internal personnel escape is not suitable and inconvenient, especially in winter. In the case of icing, and if the escape personnel in the rear are too heavy, it is easy to injure the escape personnel in front, the sliding speed is uncontrollable, and it is easy to cause unnecessary injuries. Practical, so it is necessary to develop a relatively simple and more efficient rapid rescue fire truck.
