【摘要】：路面铣刨机是沥青路面养护施工的主要机种之一，主要用于公路、机场、货场及停车场等沥青混凝土路面的维修及翻新。铣刨机施工作业时，铣刨转子直接参与铣削作业，它的性能参数直接影响到铣刨机作业质量的好坏，研究其性能参数对作业质量的影响规律，对提高和改善铣刨机的作业质量有着重要意义，同时也可以为铣刨转子的生产研制提供参考。本文围绕着铣刨机的作业质量与其铣刨转子的结构参数、运动参数的关系，，进行了以下研究：分析了作业质量的影响因素，对作业质量与转子结构参数的关系进行了研究；通过对国内外铣刨转子参数的统计分析，确定了转子直径与最大铣刨深度之间的关系；建立了铣削转角与转子直径、铣刨深度的数学模型，借助MATLAB绘制了不同转子直径条件下最大切削角与铣削深度的关系曲线；研究分析了螺旋升角、抛料板的安装对回收率的影响，确定了铣削旧料能够被集料皮带收集到的条件，通过建立的行走作业速度与铣刨深度的数学模型，绘制了在防干涉铣削与功率匹配两种条件下的作业速度与铣刨深度的特征曲线，并求出了最佳铣削点X；根据最佳铣削粒径范围得出了用以确定铣削作业速度和转子转速的计算公式；利用切削图，分析了铣削速度对铣削旧料粒径大小的影响。最后进行铣刨机现场铣削沥青路面的试验，对采集到的试验数据进行了研究分析，得出铣刨深度一定时，当铣削速度为6m/min左右时作业质量最好。
[Abstract]:Pavement milling machine is one of the main kinds of asphalt pavement maintenance and construction, mainly used in the maintenance and renovation of asphalt concrete pavement such as highway, airport, cargo yard and parking lot. Its performance parameters directly affect the quality of the milling machine. It is of great significance to study the influence of the performance parameters on the working quality of the milling machine, and to improve the working quality of the milling machine. At the same time, it can also provide a reference for the production and development of milling and planing rotor. In this paper, the relationship between the working quality of the milling machine and the structural parameters and motion parameters of the milling rotor is studied as follows: the influencing factors of the working quality are analyzed, and the relationship between the working quality and the structural parameters of the rotor is studied; The relationship between the rotor diameter and the maximum milling depth is determined through the statistical analysis of the rotor parameters at home and abroad, and the mathematical model of milling angle, rotor diameter and milling depth is established. The relationship curve between maximum cutting angle and milling depth under different rotor diameters is plotted by MATLAB, the influence of spiral angle and plate installation on the recovery rate is analyzed, and the conditions under which the old milling materials can be collected by aggregate belt are determined. Based on the mathematical model of walking speed and milling depth, the characteristic curves of operation speed and milling depth under two conditions of anti-interference milling and power matching are drawn. The optimum milling point X and the formula used to determine the milling speed and rotor speed are obtained according to the optimum milling particle size range. The effect of milling speed on the particle size of used milling materials is analyzed. Finally, the experiments of milling asphalt pavement by milling machine on the spot are carried out, and the collected test data are studied and analyzed, and the results show that the milling depth is constant. When milling speed is about 6 m / min, the operation quality is the best.
