The invention discloses a method for detecting the posture of a lifting hook of a crane, a controller and the crane. The method comprises the following steps: acquiring working condition data of the crane in a current working state, calculating ideal supporting leg counter-force of each supporting leg of the crane according to the working data in the current working state, and acquiring actual supporting leg counter-force of each supporting leg of the crane in the current working state, and determining the lifting hook posture of the crane in the current state according to the relationship between the ideal support leg counterforce and the actual support leg counterforce of each support leg. The swing posture of the lifting hook is associated with the counter-force of the supporting legs of the crane, the posture of the lifting hook of the crane is determined through the ideal supporting leg counter-force and the actual supporting leg counter-force of the supporting legs in the current operation state of the crane, the detection process is simple, no complex mechanical structure needs to be added, the limitation of the arrangement space is small, the overall cost is lower, and the structure is simpler.
本申请公开了一种用于检测起重机吊钩姿态的方法、控制器及起重机。该方法包括:获取起重机当前作业状态下的工况数据,根据当前作业状态下的工作数据计算出起重机各支腿的理想支腿反力,获取起重机的各支腿当前作业状态下的实际支腿反力,根据各支腿的理想支腿反力和实际支腿反力的关系确定当前状态下起重机的吊钩姿态。本申请将吊钩的摇摆姿态与起重机支腿反力联系起来,通过起重机当前作业状态下各支腿的理想支腿反力和实际支腿反力确定起重机的吊钩姿态,检测过程简单,无需增加复杂的机械结构,布置空间受限小,总体成本更低,结构更为简单。
