摘要
研究具有3点激光检测2轮调平机构的正三轮形式清平机底盘调平工作原理。通过坐标变换的方法建立了清平机工作部件的关键位姿坐标与3个激光检测值之间的关系模型,明确了清平机相对于激光基准平面由平到不平,然后调整2轮以恢复刀鼓与目标平面重合的原理。并计算得出为纠正不平量而需要进行调整的2后轮各自的调整行程。采用三维软件建立清平机底盘的模型,并对自动调平调整机构进行了运动学仿真。结果表明:本研究所设计的清平机在施工中达到了8 mm的控制精度。
The tricycle chassis with 3 measuring and 2 regulating configurations has been designed.The model between the key position-attitude detection and the leveling adjust attitude has been established.This paper also discusses the principle and the process of the working parts from parallel to un-parallel and then parallel with the reference laser plane based on the adjustment of the two back wheel,and then calculates the adjustment for the balancing process of different measurement of the three laser receivers.The simulation model of the adjustment is created in pro/E and has gone through the motion analysis.The grader designed based on the theory of this text exhibits the precision of 8 mm.
