Quick rescuing and fire fighting truck

Abstract

The invention discloses a quick rescuing and fire fighting truck which comprises a truck body, a rotation table, a first hydraulic cylinder, a second hydraulic cylinder, a stretchable arm, a supporting arm, a speed regulating motor, a driving wheel, a driven wheel, a tensioning wheel, a chain, a conveying plate and a high-altitude rescuing platform. The rotation table and the supporting arm are arranged above the truck body, the rotation table is provided with the stretchable arm connected with the first hydraulic cylinder, the stretchable arm is connected with one end of the supporting arm, the other end of the supporting arm is connected with the second hydraulic cylinder, a driving wheel electrically connected with the speed regulating motor is arranged at the bottom end of the stretchable arm, and a driven wheel is arranged at the top end of the stretchable arm; and the driving wheel, the driven wheel and the tensioning wheel are provided with the matched chain, the chain is provided with a movably-connected conveying plate, and the high-altitude rescuing platform is arranged at the topmost end of the stretchable arm. The quick rescuing and fire fighting truck is reasonable in design, not prone to fall, simple in operation, controllable in descending speed and free of secondary injuries, trapped persons can be conveyed in a circulated manner, the rescuing rate is greatly increased, the conveying direction is far away from a fire catching point, and the safety performance is high.

Description

technical field [0001] The invention belongs to the technical field of fire fighting and rescue, and in particular relates to a fast rescue fire truck. Background technique [0002] 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 tr...

Problems solved by technology

[0003] 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 the low efficiency, it is very difficult for rescued people to descend from the aerial ladder to the ground. People who are afraid of heights, old, weak or injured cannot get down, and the aerial ladder truck is required. 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
