Excavator rotation control method, excavator rotation system and excavator
The invention relates to the field of engineering machinery, in particular to an excavator rotation control method, an excavator rotation system and an excavator. The excavator rotation control methodcomprises the following steps of acquiring a working state of a bucket arm cylinder; if the bucket arm cylinder is in a state of driving a bucket arm of the excavator to perform unloading, acquiringa working state of a rotary motor; and if the rotary motor drives the excavator to rotate, communicating a working oil path of the rotary motor with a rod cavity of the bucket arm cylinder in order tomake hydraulic oil in the working oil path flow to the rod cavity under the action of the rotary potential energy of the excavator and drive the bucket arm to perform unloading. According to the excavator rotation control method, the rotary potential energy of the excavator can be recycled when the excavator is rotary and the bucket arm of the excavator is unloaded, and the recycled rotary potential energy is transferred to the bucket arm in a hydraulic energy manner and is used as an auxiliary power source to drive the bucket arm to perform unloading in order to reduce the energy consumptionand the use cost of the excavator.
本发明涉及工程机械领域，具体而言，涉及一种挖掘机回转控制方法、挖掘机回转系统和挖掘机。一种挖掘机回转控制方法，包括：获取斗杆油缸的工作状态；若斗杆油缸处于驱动挖掘机的斗杆进行卸载的状态时，获取回转马达的工作状态；若回转马达处于驱动挖掘机进行回转时，则将回转马达的工作油路与斗杆油缸的有杆腔导通，以使得工作油路中的液压油在挖掘机的回转势能的作用下向有杆腔流动，并驱动斗杆进行卸载。该挖掘机回转控制方法能够在挖掘机处于回转以及挖掘机的斗杆卸载时，回收挖掘机的回转势能，并将回收到的回转势能以液压能的方式转移给斗杆，并作为辅助动力源驱动斗杆进行卸载，以降低挖掘机的能耗以及使用的成本。
