The invention relates to the technical field of transportation tools, and discloses a scissor-fork type lifting device control method and a scissor-fork type lifting device.The scissor-fork type lifting device comprises a scissor-fork connecting rod assembly and a driving assembly, and the scissor-fork connecting rod assembly comprises a plurality of connecting rods hinged in a scissor-fork mode; the method comprises the steps that a driving assembly is controlled to drive a shear fork connecting rod assembly to conduct on-load lifting self-inspection so as to determine the function relation between the vertical displacement h1 and the horizontal displacement x1 of the shear fork connecting rod assembly, an actual lifting function is obtained, and motion trail prediction of the shear fork connecting rod assembly can be achieved; control parameters are calculated according to the set lifting height and the actual lifting function, and the driving assembly drives the shear fork connecting rod assembly to be lifted to the set lifting height according to the control parameters. And the influence of a gap of a hinged joint point of the connecting rod on the lifting precision can be effectively reduced.
本发明涉及运输工具技术领域,公开一种剪叉式举升装置控制方法及剪叉式举升装置,剪叉式举升装置包括剪叉连杆组件和驱动组件,剪叉连杆组件包括多个剪叉式铰接的连杆;方法包括:控制驱动组件驱动剪叉连杆组件带负载升降自检,以确定剪叉连杆组件的垂直位移量h1和水平位移量x1的函数关系,获得实际举升函数,可实现剪叉连杆组件的运动轨迹预测;根据设定举升高度和实际举升函数计算出控制参数,驱动组件根据控制参数驱动剪叉连杆组件举升至设定举升高度。可以有效降低连杆的铰接关节点的间隙对举升精度的影响。
