二、自动找平基准的选择摊铺机在作业时,熨平板处于浮动状态,使摊铺机本身具有一定的自动找平功能。但是,由于摊铺机所处工作条件的复杂性和随机性,仅靠这种功能还远不能满足现代道路施工对摊铺质量的要求,碾压后路面的平整度仍不理想,于是,近代的摊铺机又附加了自动找平系统。自动找平系统包括误差信号传感装置、信号处理和控制指令装置、终端执行装置3大部分。其工作是依靠系统中的机械、电控和液压三者形成合理的匹配关系来进行的。传感器的跟踪弓子始终沿某一与路面设计标高平行的基准运动,将下底
Second, the choice of automatic leveling benchmark Paver in the operation, the screed is in a floating state, so that the paver itself has some automatic leveling function. However, due to the complexity and randomness of the working conditions of the paver, the pavement quality can not be satisfied by the modern road construction because of the complexity and randomness of the working conditions of the paver. After the rolling, the smoothness of the pavement is still not satisfactory. Therefore, The paver has an additional automatic leveling system. The automatic leveling system includes error signal sensing device, signal processing and control instruction device, and terminal execution device 3. Its work is to rely on the system of mechanical, electrical control and hydraulic pressure to form a reasonable match between the three carried out. The sensor’s tracking bow always follows a reference movement parallel to the pavement design elevation and moves the lower base
