The invention discloses a forklift tilting oil cylinder motion buffer control system and method based on angle compensation, and belongs to the field of forklift control. The forklift tilting oil cylinder motion buffer control system comprises a tilting oil cylinder for controlling a forklift gantry to tilt forwards and backwards, a lifting oil cylinder for controlling a pallet fork to lift and acontroller. A first angle sensor for measuring the inclination angle of the portal relative to the vertical plane, a second angle sensor for measuring the inclination angle of a vehicle body relativeto the horizontal ground and a pressure sensor are connected to the signal input end of the controller, and a display, a forward tilting proportional valve for controlling forward tilting oil of the tilting oil cylinder, a backward tilting proportional valve for controlling backward tilting oil of the tilting oil cylinder and a lifting electromagnetic valve for controlling lifting oil of the lifting oil cylinder are connected to the signal output end of the controller. According to the forklift tilting oil cylinder motion buffer control system and method based on the angle compensation, the defect that the portal cannot tilt to the designed maximum angle size or move to the maximum position but is not buffered in time due to portal deformation caused by uneven ground and heavy load can beeffectively overcome, the applicability is high, and the requirements of different working conditions and operation sites can be met.
本发明公开了叉车控制领域的一种基于角度补偿的叉车倾斜油缸运动缓冲控制系统及方法,包括用于控制叉车门架前后倾斜的倾斜油缸以及控制货叉起升的起升油缸,还包括控制器,控制器的信号输入端连接有测量门架相对竖直平面的倾斜角度的第一角度传感器、测量车身相对于水平地面的倾斜角度的第二角度传感器、压力传感器,控制器的信号输出端连接有显示器、控制倾斜油缸前倾油液的前倾比例阀、控制倾斜油缸后倾油液的后倾比例阀以及控制起升油缸起升油液的起升电磁阀。本发明可有效解决因地面不平和重载导致门架形变而造成的门架无法倾斜到设计最大角度尺寸或运动到最大位置但没有及时缓冲的弊端,适用性强,能够满足不同工况和作业场地的要求。
