The invention relates to the technical field of engineering machinery, in particular to a milling machine slip control method which comprises the following steps: S1, setting slip preset pressure and optimal operation pressure of a working pump, and setting a cutter of a milling machine to start working; s2, whether the milling machine slips or not is detected, if not, the working pump works according to the optimal working pressure, and if yes, the next step is carried out; s3, entering slip-off control; s4, whether the output pressure of the working pump is not larger than the preset slipping pressure or not is judged, and if yes, the next step is carried out; and S5, controlling the displacement of the hydraulic motor corresponding to the slipping wheel to be reduced, synchronously reducing the displacement of the working pump so as to keep the speed of the milling machine constant until the milling machine is out of trouble, and returning to the step S2. The skid type can be judged, it is guaranteed that the vehicle running speed is stable in the anti-skid program control process, and the operation efficiency is guaranteed.
本发明涉及工程机械技术领域,尤其涉及一种铣刨机打滑控制方法,其包括如下步骤:S1、设定工作泵的打滑预设压力和最佳作业压力,铣刨机下刀开始工作;S2、检测所述铣刨机是否打滑,如果否,所述工作泵按照所述最佳作业压力工作,如果是,则进行下一步;S3、进入脱滑控制;S4、判断所述工作泵的输出压力是否不大于所述打滑预设压力,如果是,则进行下一步;S5、控制存在打滑的车轮对应的液压马达的排量下降,同步降低所述工作泵的排量,以使所述铣刨机的速度保持恒定,直至脱困,返回步骤S2。本发明能够判断打滑的类型,保证防滑程序控制过程中车辆行驶速度稳定,保证作业效率。
