The invention discloses an optimization method of a scissor lifting mechanism, the scissor lifting mechanism and a transport vehicle. The invention discloses a labor-saving optimization method for a scissor lifting mechanism. The labor-saving optimization method comprises the following steps: (1) optimizing the structure of the scissor lifting mechanism; (2) carrying out labor-saving optimization verification on the optimized scissor lifting mechanism structure; (21) analyzing the stress at the shear fork connecting pin shaft and the lead screw before setting optimization; (22) analyzing the stress at the shear fork connecting pin shaft and the lead screw after optimization; and (22) enabling the stress condition of the optimized structure to be superior to that of the structure in the existing scheme. By exchanging the positions of a hinge fixing point and a sliding block of an existing product, the shear fork sliding block and the push rod sliding block are located on the same side; and under the condition that the lifting height and the overall size are kept unchanged, the stress of the connecting pin shaft of the shear fork arm is greatly reduced, the stress condition of the shaft sleeve at the position is improved, and the service life of the shear fork structure is effectively prolonged.
本发明公开了剪叉举升机构的优化方法及剪叉举升机构及运输车。剪叉举升机构省力的优化方法,包括(1)对剪叉举升机构的结构进行优化;(2)对优化后的剪叉举升机构结构进行省力优化的验证;设定优化前对剪叉连接销轴处和丝杠受力进行分析得到:(21)优化后对剪叉连接销轴处和丝杠受力进行分析得到:(22)优化后结构的受力情况优于现有方案的结构。本发明通过交换现有产品铰接固定点和滑块的位置,让剪叉滑块与推杆滑块同在一侧;在举升高度和总体尺寸保持不变的情况下,大幅度的降低了剪叉臂连接销轴的受力,改善该处轴套受力情况,有效延长剪叉结构的使用寿命。
