The super high-rise guide climbing work platform is a new type of high-altitude electromechanical integration equipment with high-tech content.It gradually enters people's field of vision in the maintenance work of the external walls of buildings,and as the height of buildings increases,the required construction equipment is getting higher and higher.The guide frame of the super high-rise guide climbing work platform is the support and load-bearing structure of the working platform structure,which is especially important for the research of the strength,rigidity and stability of the guide frame.The guide structure directly affects the working performance of the whole machine.Therefore,the article makes the static analysis and optimization on the guide structure of the super high-rise guide climbing working platform,thus providing a theoretical basis for the development and use of super high-rise construction equipment products.In this paper,according to the standard of the guide climbing platform,the theoretical calculation and analysis of the displacement of the super high-rise guide structure are carried out.According to the equivalent inertia moment theory of the lattice component,the second-order theory of lateral displacement and the precise that the connection of the wall frame structure is flexible,the model matrix reduction method using the transfer matrix is used to obtain the corresponding guide frame and the stiffness matrix of the wall frame structure is conducted,and the static calculation of the maximum independent height of the guide frame structure according to national standards;Secondly,used ANSYS software guide frame structure to carry out static simulation analysis,the stress countour plot and deformation displacement cloud map under different dangerous conditions are obtained.The most dangerous working conditions of the guide frame structure are determined by the results,and the working capacity of the guide frame structure is defined.The criteria is based on the evaluation criteria of the working capacity of the guide structure,and the displacement deformation of focusing is considered;Thirdly,by changing the standard section of the different cross-section shapes of the guide frame structure,the standard arrangement of the rods,the dimensions,the type of wall frame arrangement and the dimensions,the spacing of the wall frame arrangement and so on.The maximum deformation displacement of the guide frame structure under different parametersis achieved;Finally,based on the results of static buckling analysis of the guide structure,and the evaluation criteria of the guide structure,considering the buckling analysis results,the impact of different parameters of the guide structure are analyzed.The primary and secondary parameters are extracted,and the combination of different parameters is obtained.Finally,the frame structure is optimized and statically analyzed to ensure the optimization of the working ability of the guiding frame structure.This paper takes the existing guiding frame structure as the research object.The strength,stiffness and stability of the guide frame structure of the super high-rise-guide frame climbinwork platform are analyzed by using material mechanics,structural mechanics,steel structure and finite element theory and judging criteria for structural work ability is obtained;Based on the different parameters related to the guide structure,the paper analyzes the different parameters and finally obtains the final scheme of the guide frame optimization.The optimal solution makes the working performance of the guide frame fully exerted,which provides a certain reference for the design and development of similar products.
