    摘要:

    针对传统剪叉式升降平台的伸缩比小、升降距离有限等问题,设计了一种以多弹簧为驱动源的新型剪叉式升降平台。首先,基于最大负载计算出升降平台的最大驱动力;其次,研究了平台在完全压缩状态下,弹簧所能提供的最大驱动力,并分析了与弹簧相连的两侧加强柱的变形情况,以确保平台平稳运行;再次,通过建立静力学模型,推导了力矩平衡方程,分析了各层铰接点的受力情况;最后,通过样机实验证明了所设计的升降平台具有良好的展开性与稳定性。

    Abstract:

    In view of a solution of the small expansion ratio and limited lifting distance of traditional scissor lift platforms, a new type of scissor lift platform has thus been designed with multiple springs as the driving source. Firstly, a calculation is to be made of the maximum driving force of the lifting platform based on the maximum load; Secondly, a research is to be conducted on the maximum driving force that the spring can provide for the platform in a fully compressed state, followed by an analysis of the deformation of the reinforcing columns on both sides connected to the spring so as to ensure the smooth operation of the platform. Thirdly, a static mechanical model is to be developed, thus deriving moment equilibrium equations, with an investigation of the forces acting on the hinged joints at each level. Finally, prototype experiment results prove that the designed lifting platform is characterized with good expandability and stability.
