Research On Complete Equipment For Rapid Storage And Transportation Of Concrete Components Based On Vacuum Sucker Technology

Since China’s reform and opening up,rapid economic development,the living standard of people from poor to rich,now before the domestic principal contradiction have also changed,the level of people’s life demand is higher and higher,especially in public infrastructure.In today’s continuous development,concrete structures because of its high strength,good durability,the advantages of wide raw material sources,is still widely used in electric power transportation,communication lines and other projects.The increasing demand for concrete pipe piles requires manual hoisting methods for traditional production lines.A challenge was initiated.In order to improve the concrete hoisting efficiency,the automation and intelligence of the concrete production line are further realized,it is imperative to design a set of automated and fast storage and transportation equipment.In order to design a rapid concrete hoisting equipment,based on the existing research,a vacuum chuck suitable for concrete with special shape is presented,the theory of fluid mechanics and the simulation software Fluent were used to verify it.The principle of action of the leech sucker was analyzed,And the structure optimization design by the vacuum suction cups.Finally,using the Ansys design strength analysis of lifting equipment,verifies the correctness of design.According to the existing production line layout and hoisting method of a power line equipment factory,it is proposed to design the equipment based on vacuum suction cup technology.Through bionic optimization of vacuum suction cup,the adsorption performance of suction cup is improved,and the key parts of mechanical structure of the equipment are simulated and optimized,and the safe,fast and automatic storage and transportation of pipe piles are realized.Aiming at the existing production line layout and hoisting method of a power line equipment factory,as well as related design conditions and status quo,a set of automatic and rapid hoisting equipment for concrete pipe piles is designed.The solution can be extended to other related types of rapid storage and transportation equipment for pipe piles.A new vacuum suction cup structure is proposed according to the structure characteristics of pipe stake and vacuum adsorption theory.Based on the hydrodynamic theory,the Reynolds number of fluid in the pipe stake is calculated to determine the flow state of the suction cup gas as turbulent flow.Then,the realizable k-εmodel in the Reynolds time-averaged equation in the Fluent fluid module of ANSYS Workbench is used to perform the hydrodynamic analysis of the fluid field in the suction cup of different diameter suction outlets.The pressure cloud diagram is analyzed,and 60mm air outlet is selected to ensure better absorption.The research object of this project was the leech.The optimal structure of this project was confirmed.Through a group of experiments,the previous assumptions were proved to be reasonable.On the basis of this,the structure of the vacuum suckers designed was also improved by the simulation.And the simulation experiments were carried out in Fluent.The experimental results show that the maximum negative pressure is reduced by 1 after optimization×10~4MPa indicates that the proposed optimization method is valid and can provide theoretical guidance for subsequent vacuum suction cup research.The principles of the FEA were introduced,and the main parts of the designed vacuum lifting equipment were made a simulation of the FEA.The design of the structural parts of the straw and beam was done with Solid Works three-dimensional design software,and the fluid and static stress analysis of the straw and beam was done with the finite element analysis software,ANSYS Workbench,which yielded the analysis results.The results show that the designed vacuum suction sling meets the static stress analysis conditions and the design results are fully correct.The research shows that the rapid storage and transportation equipment of concrete components based on vacuum suction cup designed in this paper meets the strength requirements during the hoisting process.By optimizing the bionic design of the suction cup,the fixing problem of the concrete pipe stake is solved.The flow field analysis shows that the adsorption force generated by the bionic vacuum suction cup can meet the requirements during the hoisting process.
