The invention relates to the technical field of cranes, and particularly provides a lifting hook control method, a lifting hook control system and engineering equipment. During use, in an extension stage, a first pump and a second pump jointly drive a hydraulic cylinder, so that the extension efficiency of the hydraulic cylinder can be improved; in the retraction stage, due to the gravity factor, the movement direction of each knuckle arm is downward during arm retraction, the oil cylinder movement direction of the hydraulic cylinder is also downward, the knuckle arms move downwards to press the oil cylinder to move downwards more easily, and therefore high retraction efficiency can be achieved only by driving the hydraulic cylinder to retract through the first pump, and the second pump executes lifting hook follow-up. In conclusion, in the lifting hook follow-up process, a more appropriate control strategy can be executed according to the specific telescopic arm state, and the arm extending action, the arm retracting action and the lifting hook follow-up action can be more efficiently carried out while it is guaranteed that the lifting hook is within the safety range.

    本申请涉及起重机技术领域,具体提供了一种吊钩控制方法、吊钩控制系统和工程设备,在使用时,在伸阶段中,第一泵和第二泵共同驱动液压缸能够提高液压缸的伸出效率;在缩阶段中,由于重力因素,缩臂时各个节臂的运动方向向下,并且液压缸的油缸运动方向也向下,节臂向下运动压迫油缸可以更轻易地向下运动,因此仅第一泵驱动液压缸回缩便可以达到较高的回缩效率,第二泵则执行吊钩随动。总结地说,在吊钩随动过程中,本方面能够根据具体的伸缩臂状态执行更合适的控制策略,在保证吊钩处于安全范围内的同时,能够更高效率地进行伸臂动作、缩臂动作以及吊钩随动动作。
