Loader bottom fork device lifting control method and control system and loader
The invention provides a lifting control method and system for a bottom fork device of a loading machine and the loading machine, and solves or improves the technical problem that in the prior art, in the lifting process of the loading machine, the real-time inclination angle of the bottom fork device is difficult to keep consistent with the inclination angle of a bottom fork adjusted in advance, so that safety accidents are caused by shaking. According to the loading machine bottom fork device lifting control method, the target bottom fork angle is set, the fitting curve between the simulated movable arm angle and the simulated rocker arm angle is generated through fitting according to the initial posture of the loading machine, and the loading machine bottom fork device lifting control method is achieved on the basis of the fitting curve. The angle correction current value of the bottom fork device is calculated according to the real-time simulation movable arm angle and the real-time simulation rocker arm angle so as to correct the starting current value of an electromagnetic proportional valve of a bottom fork oil cylinder, the bottom fork oil cylinder is controlled to stretch out or retract according to the corrected current value, parallel lifting of the bottom fork device is achieved, and potential safety hazards are avoided.
本申请提供了一种装载机平叉装置举升控制方法、控制系统及装载机，解决或改善了现有技术中装载机举升过程平叉装置的实时倾斜角度与事先调整好的平叉倾斜角度难以保持一致，造成抖动发生安全事故的技术问题。本申请提供的装载机平叉装置举升控制方法，通过设定目标平叉角度，并根据装载机的初始姿态拟合生成模拟动臂角度与模拟摇臂角度之间的拟合曲线，基于拟合曲线，根据实时模拟动臂角度以及实时模拟摇臂角度计算平叉装置的角度修正电流值，以修正平叉油缸电磁比例阀的启动电流值，并以修正后的电流值控制平叉油缸的伸出或收缩，实现平行举升平叉装置，避免安全隐患。
