【摘要】：随着沥青路面总量的不断增加,养护工程也日益庞大,社会对道路畅通、安全、舒适、美观的要求越来越高,而沥青路面养护机械便由此产生。沥青养护设备能够对沥青路面的病损进行全面高速有效的养护,大大提升公路养护的质量,并且使养护成本大大降低,同时也减轻了人工的劳动负荷,对病损路面进行有效维护保障公路的畅通。本文设计了一种新型沥青路面养护车,对加热搅拌型滚筒料仓进行了研究,对其保温料仓进行相关设计,并就滚筒料仓设计中的滚筒结构、搅拌功能、出料系统、加热保温方式等进行了分析。设计中料仓采用滚筒式结构,内部焊接有螺旋叶片,以实现顺时针旋转对混合料进行搅拌、逆时针旋转实现卸料的功能;出料系统采用螺旋出料器,防止混合料发生离析;料仓采用红外辐射加热方式,并在滚筒与外壳之间设置保温层,实现对沥青混合料的保温。利用Fluent仿真分析软件对混合料的加热过程进行仿真研究,建立了沥青混合料的分析模型,分析了混合料加热的均匀性与加热效率,为企业产品设计提供了理论依据。
[Abstract]:With the increasing of the total amount of asphalt pavement, the maintenance project is becoming more and more huge. The society demands more and more smooth, safe, comfortable and beautiful roads, and the asphalt pavement maintenance machinery is produced. Asphalt maintenance equipment can carry out comprehensive, high-speed and effective maintenance of asphalt pavement damage, greatly improve the quality of highway maintenance, and greatly reduce the maintenance costs, as well as reduce the manual labor load. Effectively maintain the damaged road surface to ensure the smooth flow of the highway. In this paper, a new type of asphalt pavement maintenance vehicle is designed, and the heating mixing drum silo is studied, and the heat preservation silo is designed, and the drum structure, mixing function and discharging system in the design of the drum silo are discussed. The methods of heating and heat preservation were analyzed. In the design of the silo, the drum structure is adopted, and the spiral blade is welded inside to realize the function of mixing the mixture clockwise, rotating counterclockwise to unload the mixture, and to prevent the segregation of the mixture by adopting the spiral discharging device in the discharging system. The heat preservation of asphalt mixture is realized by using infrared radiation heating method and setting insulation layer between drum and shell. The heating process of asphalt mixture is simulated by Fluent software, and the analysis model of asphalt mixture is established. The uniformity and efficiency of mixture heating are analyzed, which provides a theoretical basis for the product design of enterprise.
