Milling machine control method, milling hydraulic system and milling machine
The invention relates to the technical field of engineering machinery, and particularly discloses a milling machine control method, a milling hydraulic system and a milling machine, the milling machine control method is implemented through the milling machine, and when the milling machine works through the milling machine control method, due to the fact that the displacement of a milling pump and the displacement of a milling motor can be both adjusted, the milling machine can work stably. S20, the displacement of the milling pump and/or the displacement of the milling motor are/is adjusted, so that the rotating speed V < actual > of the milling drum is equal to V < set >. S40, judging whether the real-time pressure value P < actual > in a milling hydraulic system of the milling machine is larger than the set allowable maximum pressure value P < set >, if yes, indicating that the working resistance of a milling drum is large, and executing S40, and setting P as the maximum pressure value borne by the milling hydraulic system: reducing the rotating speed of the milling drum or reducing the running speed of the milling machine, and if not, judging that the working resistance of the milling drum is large; therefore, the pressure P < actual > in the milling hydraulic system is reduced. According to the arrangement, the rotating speed of the milling drum and the rotating speed of the engine are respectively and independently controlled, the requirements of various working conditions are met, the construction energy consumption is reduced, and the construction efficiency is improved.
本发明涉及工程机械技术领域，具体公开了铣刨机控制方法、铣刨液压系统及铣刨机，该铣刨机控制方法通过铣刨机实施，铣刨机通过该铣刨机控制方法工作时，由于铣刨泵的排量和铣刨马达的排量均可以调节，所以S20：调整铣刨泵的排量和/或铣刨马达的排量，以使铣刨鼓的转速V实＝V设。判断铣刨机的铣刨液压系统中的实时压力值为P实是否大于设定允许的最大压力值P设，若是，则说明铣刨鼓的工作阻力较大，需要执行S40，P设为铣刨液压系统承受的最大压力值：降低铣刨鼓转速或降低铣刨机行车速度，以降低铣刨液压系统内的压力P实。上述设置实现了铣刨鼓的转速和发动机的转速分别独立控制，满足了各种工况需求，进而降低了施工能耗，提升了施工效率。
