摘　　要：现有的剪叉升降机存在工作状态升降杆受力不均衡的缺点。为了弥补这一缺陷,设计了一种新型的剪叉升降机构,使其能够在实现同等功效的前提下,具有结构对称性的特点,有效地改善了升降机构受力不均匀的缺点,增大了剪叉机构的工作行程。对剪叉机构进行了力学分析,得出通用计算方法,且通过Matlab软件绘制相应图形,优化设计参数。The unbalanced force of the lifting rod exists in the existing traditional fork lifter.For this defect,this paper designs a new type of the fork lifting mechanism.Its structure is characteristic of symmetry,thus solving the uneven force of the lifting mechanism and increasing the working stroke of the scissors mechanism.Its mechanical analysis is carried out and the general calculation method is obtained.Matlab software is used to draw the corresponding graphics which are used to optimize the design parameters.
