[Abstract]:In this paper, the situation of airport fire fighting and rescue is becoming more and more complicated, especially the research and analysis of the special situation and the difficult problem of fire fighting for aircraft which need to chase the plane in the forced landing and gliding. The aim of this paper is to meet the actual combat needs of fast fire fighting in the airport. Its main function is located in the airport fire engine with rapid emergency response capability. By analyzing and studying the relevant standard requirements and technical characteristics of the airport rapid mobilization fire engine, a second class chassis of a high-power off-road vehicle is designed. It is equipped with an independent fire engine to drive the fire pump, and its own water or foam can be quickly operated by intelligent control system. This paper is based on strict compliance with national standards and industry standards. Taking the second class chassis of a high power off-road vehicle as the platform, the technical performance of the fire engine is determined as a whole. On this basis, the structure of the body, the form of the water tank, the load of liquid, the fire power system, the jet system, the intelligent control system, are discussed. The structure, principle and characteristics of various parts such as additional electrical equipment are studied and designed, the body structure and tank connecting seat are analyzed by finite element method, and the axle load of the whole vehicle is checked. In this paper, through the research and analysis of the fire fighting power system, the selection of the independent fire engine and elastic coupling is optimized through the matching calculation of the relevant configuration. According to the type and characteristics of the power transmission, To determine the type of hydraulic gear box, to study the design method and steps of hydraulic gear box. By studying the calculation method of transmission ratio, the main parameters such as transmission ratio and gear tooth number of hydraulic clutch gear box are calculated. A hydraulic clutch control device is proposed. The main specification parameters, structure and working principle of hydraulic gearbox are determined, and the necessary strength checking calculation is carried out. By analyzing the composition and characteristics of the fire fighting jet system, the jet system is studied, and according to the type of fire pump, According to the practical requirements of fire extinguishing, the hydraulic design of impeller, the size design of pump body and the design of key strength of fire pump are studied, and the technical parameters, structure and principle of fire pump are determined. Finally, according to the requirements of relevant national standards and industry standards, the whole vehicle is tested and verified, and the vehicle is improved according to the test conditions. In order to meet the standard requirements of the airport fire engine, the problems in the design are summarized, and the further improvement is pointed out for the design work in the future.
