Control method and control device for rotary braking of excavator and excavator
The embodiment of the invention provides a control method and device for rotary braking of an excavator and the excavator, and belongs to the technical field of engineering machinery. The method is applied to an excavator rotation control system, the rotation control system comprises a control mechanism, a main pump and a rotation electromagnetic proportional valve, and the method comprises the steps that a pilot signal of the control mechanism and a pressure signal of the main pump are obtained; the working states of the excavator are determined according to the pilot signal and the pressure signal, and the working states comprise the rotation braking state, the rotation state and the rotation static state; and when it is determined that the working state is the rotary braking state, the current of the rotary electromagnetic proportional valve is controlled to be reduced according to the preset duration. In the process, the working state of the excavator is judged according to the obtained pilot signal and the pressure signal, and when the working state is the rotary braking state, the current of the rotary electromagnetic proportional valve is reduced according to the preset time, so that the impact or the generated drift amount borne by the excavator in the rotary braking process is reduced, and the excavator is protected. And normal use of excavator equipment is guaranteed.
本发明实施例提供一种挖掘机回转制动的控制方法、控制装置及挖掘机，属于工程机械技术领域。该方法应用于挖掘机回转控制系统，回转控制系统包括操纵机构、主泵以及回转电磁比例阀，包括：获取操纵机构的先导信号和主泵的压力信号；根据先导信号和压力信号确定挖掘机的工作状态，其中，工作状态包括回转制动状态、回转状态以及回转静止状态；当确定工作状态为回转制动状态时，控制回转电磁比例阀的电流根据预设时长减小。该过程通过对获取得到的先导信号和压力信号判断挖掘机的工作状态，当工作状态为回转制动状态时，根据预设时间减小回转电磁比例阀的电流，以使挖掘机在回转制动过程中减小受到的冲击或产生的漂移量，保障挖掘机设备的正常使用。
