[Abstract]:Rapid chassis circular pit milling planer is a new type of road maintenance equipment, the whole car mechanization, high degree of automation, convenient and flexible operation, simple construction technology, with rapid mobility, It is a special equipment specially invented for highway circular pit excavation. When repairing the local damage of asphalt pavement, the unique vertical milling and planing device can efficiently milling out regular circular potholes with perpendicular edges to avoid manual dressing of the edges of the potholes. The dust is sucked into the settling box by the high speed negative pressure airflow produced by the fan to prevent dust pollution. The milling planer has changed the special chassis type of the traditional milling machine and adopted the second class automobile chassis, which can turn the field quickly after finishing the work. Circular pit repair has the advantages of low stress concentration, strong resistance to driving load and low temperature deformation, and good ride comfort. At present, the research of rapid chassis circular pit milling planer is still in its infancy, but it has the potential market value because of its unique advantage in repairing the local damage of highway asphalt pavement. In this paper, the overall design and performance of the quick chassis circular pit milling planer are studied. This paper summarizes the classification method and working principle of milling planer, and expounds the development history and present situation of milling planer at home and abroad. On the basis of investigation and analysis of road maintenance demand and construction process, the functional requirements of quick chassis circular pit milling planer are clarified. By summing up the characteristics of milling machine at home and abroad and the parameters of the whole machine, the performance parameters of the quick chassis circular pit milling planer are determined, and the overall scheme of the whole car suitable for the excavation of the freeway circular pit is designed. According to the function, the quick chassis circular pit milling planer is divided into twelve subsystems, and the composition, function and working principle of each system are introduced. The general layout of the whole vehicle and the power system, transmission system, milling and planing material recovery system and unloading system of the whole vehicle are designed, and the key problems to be solved in the design are pointed out. A reasonable formula or empirical data is given for the selection calculation of each system. This paper studies the correlation performance of quick chassis circular pit milling planer, and puts forward its own evaluation calculation method on some performance evaluation indexes. Finally, the paper summarizes the content of the paper and points out the shortcomings of the paper, and the future research direction is prospected. The research work in this paper provides a design theory and performance evaluation method that can be used for reference for the design of the quick chassis circular pit milling planer, which can pave the way for the function improvement and performance optimization of the whole car in the future.
