The Research Of Asphalt Concrete Pavement Side Mode Paving Machine

During the construction process of asphalt concrete pavement, because both ends of paving mixed highway material new shop is not fixed, the clamping device, the asphalt concrete surface layer width is wider than the design. Therefore, in order not to affect the appearance, the service life of road construction and landscaping, after the mixing is paved, the excess material must be cut by saws.With the development of the national economy and the advances of the road construction technology, The application of asphalt concrete pavement is more and more widely used in our country, especially in high grade road construction. In this case, how to improve the construction technology of asphalt concrete pavement to improve the efficiency of construction has been paid more and more attention. In response to these problems, asphalt concrete pavement side mode technology can be adopted, it can pave the side mode in the edge of the road two side before asphalt concrete surface paved. These will make asphalt concrete pavement directly formed neat and straight edge in the process of paving. For solving such problems, asphalt concrete pavement side mode paving machine is designed. It can automatically follow the previously laid tag line to walk and install side mode at the same time. The mechanical structure of asphalt concrete pavement side mode paving machine is designed, including the walking steering mechanism, side mode storage mechanism, side mode transport mechanism and side mode installation mechanism. Paving machine automatic walk along the marked lines under the control of the walking steering system, and complete the laying operation of side mode in the role of installation sysyem and nailing system. It design steering control system based on single chip, and redact the control programs; In order to better accomplish the intended action, suitable pneumatic actuators and control components are chosen. Programmable logic controller are chosen. According to the control flow, the ladder of programmable logic controller has been drawn by using WPLSoft software.The paving machine can complete the operation of asphalt concrete pavement side mode automatically. It can accelerate the speed of paving and improve, the quality of side mode of pavement, and the efficiency of production.
