【摘要】：城市化的進(jìn)程越來越快，市政道路和高速公路的建設(shè)逐年增加，在我國(guó)公路事業(yè)迅猛發(fā)展的同時(shí)，也面臨一個(gè)關(guān)于如何快速高效地對(duì)已損壞路面進(jìn)行養(yǎng)護(hù)的問題。瀝青路面的小面積損壞即坑槽是城市道路和高速公路的主要病害之一，直接影響到交通的舒適性與安全性；而坑槽修補(bǔ)作業(yè)也是瀝青路面經(jīng)常性養(yǎng)護(hù)的主要作業(yè)種類之一，坑槽修補(bǔ)的質(zhì)量和壽命決定路面的運(yùn)營(yíng)質(zhì)量以及路面養(yǎng)護(hù)的總體效益。根據(jù)最新研究成果，在相同條件下，圓形坑槽修補(bǔ)質(zhì)量大大優(yōu)于方形坑槽。因此，研發(fā)一種圓形坑槽銑刨機(jī)是實(shí)現(xiàn)圓形坑槽修補(bǔ)的先決條件，滿足高速公路和市政道路的小面積破損路面的修補(bǔ)，，以較低的成本實(shí)現(xiàn)較大的收益，具有重要的現(xiàn)實(shí)意義和良好的社會(huì)效益。 本文以宋永剛教授的發(fā)明專利《瀝青路面圓形坑槽銑刨設(shè)備》為研究基礎(chǔ)，通過分析和借鑒現(xiàn)有銑刨裝置的結(jié)構(gòu)和功能原理，設(shè)計(jì)出了合理的可以開挖圓形坑槽的銑刨設(shè)備的銑刨裝置，對(duì)其主要結(jié)構(gòu)組成和工作原理進(jìn)行了詮釋。本文重點(diǎn)討論了該銑刨裝置的銑刨芯軸旋轉(zhuǎn)結(jié)構(gòu)和三級(jí)銑刨刀盤組合結(jié)構(gòu)及其有關(guān)這兩個(gè)結(jié)構(gòu)的重要參數(shù)，并給出了其相關(guān)參數(shù)的校驗(yàn)過程；討論了三級(jí)銑刨刀盤的設(shè)計(jì)和各級(jí)刀盤上刀具的布置形式，分別給出了主刀和邊刀各主要角度參數(shù)以及安裝角，并從刀具的磨損、選擇和使用等方面進(jìn)行了分析；建立了銑刨刀頭及其切削路面過程的實(shí)體模型，并通過有限元分析軟件ANSYS Workbench，設(shè)定不同的刀盤轉(zhuǎn)速和進(jìn)給速度，對(duì)銑刨刀頭切削路面過程進(jìn)行了顯式動(dòng)力學(xué)仿真，對(duì)其仿真結(jié)果進(jìn)行了分析討論；討論了瀝青路面在常溫下的破壞機(jī)理，對(duì)銑刨刀具的銑削阻力進(jìn)行了理論計(jì)算探析，給出了銑刨芯軸液壓驅(qū)動(dòng)馬達(dá)的工作負(fù)載計(jì)算式。 本文的研究工作為圓形坑槽銑刨裝置的研發(fā)提供了一種設(shè)計(jì)參考，并給出了完整的機(jī)構(gòu)設(shè)計(jì)理論和計(jì)算方法，對(duì)圓形坑槽銑刨裝置的進(jìn)一步功能完善和性能優(yōu)化有一定的參考價(jià)值。
[Abstract]:The process of urbanization is getting faster and faster, and the construction of municipal roads and highways is increasing year by year. With the rapid development of highway in China, it is also facing a problem of how to maintain the damaged road surface quickly and efficiently. The small area damage of asphalt pavement, namely pothole, is one of the main diseases of urban road and highway, which directly affects the comfort and safety of traffic, and pothole repair is one of the main types of maintenance of asphalt pavement. The quality and life of pothole repair determine the operation quality of pavement and the overall benefit of pavement maintenance. According to the latest research results, the repair quality of circular potholes is much better than that of square potholes under the same conditions. Therefore, the research and development of a circular pit milling machine is a prerequisite to achieve circular pit repair, to meet the repair of small areas of damaged road surface of highway and municipal roads, and to achieve greater benefits at lower cost. It has important practical significance and good social benefit. Based on Professor Song Yonggang's invention patent "Asphalt pavement Circular Pit Milling and planing equipment", this paper analyzes and draws lessons from the structure and functional principle of the existing milling and planing device. A reasonable milling and planing device which can excavate circular pits is designed, and its main structure and working principle are explained. In this paper, the rotating structure of the milling core shaft and the combined structure of the three-stage milling planer and the important parameters related to the two structures are discussed in detail, and the calibration process of the related parameters is given. This paper discusses the design of the three-stage milling planer and the layout of the cutter on the cutter head, and gives the main angle parameters and the installation angle of the main knife and the edge cutter, and analyzes the wear, selection and use of the tool. The solid model of milling planer head and its cutting road surface process is established. Through the finite element analysis software ANSYS Workbench, different rotating speed and feed speed of cutter head are set up, and the explicit dynamic simulation of milling planer head cutting process is carried out. The simulation results are analyzed and discussed, the failure mechanism of asphalt pavement at room temperature is discussed, the milling resistance of milling cutter is analyzed theoretically, and the working load calculation formula of hydraulic motor driven by milling core shaft is given. The research work in this paper provides a design reference for the research and development of circular pit milling planer, and gives a complete mechanism design theory and calculation method. It has certain reference value for the further function improvement and performance optimization of circular pit milling and planing device.
