沥青路面养护车开发
|
摘要
近10年我国高等级公路建设发展迅速,政府部门对高等级公路养护更加重视,投入也不断增加,因此,高等级公路养护车面临着良好的发展机遇。目前,国外高等级公路养护车比较成熟,但价格和维修成本较高。国内只有少数几家制造企业,但没有自身的核心技术,并且产品可靠性低。因此,开发新型高等级公路养护车符合国家产业政策,具有广阔的市场前景。
论文对高等级公路养护车项目开发的必要性,市场、技术的可行性和经济效益进行了综合分析,该类产品附加值高。然后,根据高等级公路沥青路面高效的热修补工艺要求,提出了该车的总体方案。该车主要由底盘、底架总成、料仓总成、加热墙总成、导热油加热系统、燃气系统、压实装置总成、废料箱总成以及电路系统等部分组成。论文主要研究了加热墙的设计、料仓加热保温系统设计。加热墙主要采用了红外线辐射导热,发热元件选用金属纤维烧结毡,结构采用加热板式框架结构;料仓加热保温系统主要采用液化气加热导热油作为传导介质,把热量传给料仓内的沥青混合料的方式,实现对材料的加热及保温。
最后,完成了样车试制。对样车的料仓容积及装载质量、沥青混合料加热升温性能、料仓保温性能和路面养护车作业可靠性进行了测试,并通过了国家权威机构的定型鉴定试验,该车可以投入批量生产。
Over the past 10 years, China has a rapid development of high-grade highway, government departments on the highway also pay more attention to this. Therefore, the maintenance machinery on high-grade highway are facing good opportunities for development. Foreign maintenance machinery on high-grade highway has more mature technologies, but the drawback is that the price and maintenance costs generally higher, so the domestic market share is not high. A few domestic car manufacturing enterprises which have capacity of making maintenance vehicles, whose product performance can be low reliability and the core technology have been not formed. Therefore, development of new maintenance vehicles on high-grade highway is suitable for the national industrial policy, which have huge market prospects.
This paper is on the need for project development of maintenance vehicles on high-grade highway and also has a comprehensive analysis on the market and technical feasibility. These products have high added value. Then, according to efficiency requirements for heating repair process on highway asphalt pavement, it's determined to the overall design of the product. The composition of overall structure of the maintenance vehicles to asphalt pavement road is that chassis cars, chassis assembly, Silo assembly, heating wall assembly, conducting oil heating systems, gas systems, compaction device assembly, waste bins and electrical systems, and another assembly parts. The focuses of the paper are that the design of heating wall, Silo assembly, silos" heating system, Silo's internal structure. Heating wall is mainly used of thermal infrared radiation, heating elements are optional to metal fiber carpets, and the structure is that heating plate frame. Silo assembly system is designed to hopper-shape structure, the advantages of which is that if asphalt mixture is in a tilt angle of the circumstance, it is facilitated to move to the spiral axis of losers, which take the initiative to lose the silo's material. Silo gas heating system is mainly used heating conducting oil, conducting oil as a conductive medium, and the way to heat transmission within the Silo asphalt mixture can be achieved with the expected heating and insulation.
Finally, after a completion of trial production prototype, a prototype of diagnostic tests will be go on: which can be included on tests of the main silo's volume and quality, test of heating performance of asphalt mixture, tests of silo's insulation performance, tests of heating performance of asphalt pavement and tests of operating reliability and so on, which are all adopted the trial identification of stereotypes of national authority and can be into mass production.
