| The double-column roadway stacker is a lifting equipment widely used in the warehousing and logistics industry.Its main function is to realize the handling of goods in the three-dimensional warehouse.The existing double-column roadway stacker has large swing and poor stability during operation,which is easy to cause safety accidents.The main factor affecting the stability of the double-column roadway stacker is the amount of deformation of the gantry structure.Therefore,this article uses a combination of mechanical analysis and software simulation to analyze the deformation of the double-column roadway stacker gantry and optimize its structure.The main research work is as follows:(1)Double column roadway stacker gets analyzed by finite element method.Taking the 1823A-02 model stacker as the research object,a three-dimensional model was established,and its deformation,stress and modal are analyzed with the help of the finite element software ANSYS Workbench to obtain parameters characterizing its performance.(2)Factors influencing on portal frame deformation are analyzed.Based on the basic theories of material mechanics and structural mechanics,the deformation amount of the mast is calculated;through the finite element analysis,and the influence law of the loading platform position on the deformation of the mast is obtained.(3)Optimization of portal structure is made.Combined with the influence law of the structure deformation of the double-column roadway stacker,by analyzing the influence law of the four-part structural parameters of the portal structure on the structure of the stacker,the portal frame is optimized under the limit working condition load,and the maximum deformation and the maximum after optimization equivalent stress has been reduced,the stiffness and stability have been improved,and the quality has been significantly reduced.(4)The stability of the stacker is verified.Taking the most unfavorable working conditions as input conditions,the actual operation process of the stacker is simulated,which shows that the stacker swing is reduced and the operation is more stable. |
