Overall Design And Key Component Analysis Of High Efficiency Hoisting Equipment For Test

At present,the application of prefabricated component assembly building is being popularized in China.After a series of policies on assembly architecture carried out by the state,China’s assembly architecture has made rapid progress.However,there are still many technical problems in the practical engineering application of prefabricated buildings,among which the hoisting problem of prefabricated components is very obvious.The existing lifting equipment can not carry on the high efficiency hoisting construction operation to the prefabricated component.Because prefabricated components are not fully standardized,and in the hoisting and transportation work of the prefabricated parts.The component support point to be unstable.It caused the risk factor has been greatly increased.In order to improve the efficient hoisting of prefabricated building components in the construction site,a high efficiency hoisting equipment for 6-degree-of-freedom test is designed and developed.(1)First of all,this paper uses Solid Works software to carry on the three-dimensional design to the high efficiency hoisting equipment for the test,and the overall modeling of the hoisting equipment for the prefabricated components is completed.The overall scheme design of component high efficiency hoisting equipment is completed,the working principle and working process of component high efficiency hoisting equipment are expounded,and the main parameters of component high efficiency hoisting equipment are determined.(2)On this basis,the six degree of freedom executive device is analyzed in detail.The key parts of pressure-driven shearing fork mechanism are designed,including three parts,hydraulic mechanism design,key component design of spatial shearing fork folding mechanism and automatic lifting hook mechanism of components.The structural selection,calculation scheme and structure design of key components are given.And Mechanical analysis,kinematic analysis and simulation are carried out for the model.(3)Finally,the finite element method is used to analyze the designed mechanism,and the finite element model of the shearing fork mechanism is established by using ANSYS finite element software command flow APDL language,and then the static analysis and modal analysis of the shearing fork mechanism are completed.The influence of cross section parameters on stress is analyzed by orthogonal test,which provides a theoretical basis for the optimization of shear fork mechanism.The simulation results show that the executive device of high efficiency hoisting equipment for prefabricated components can meet the requirements of strength and stiffness.The equipment can carry out the movement of members.The efficient hoisting equipment can control and simulation test,and can provide a certain reference value for the design of practical and efficient hoisting equipment.
