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.
