Research On The Key Technology Of Multi-station Intelligent Lifting Device

The multi-station intelligent lifting device is a dual-purpose vertical transportation platform for people and goods in the modern construction industry.In view of the disadvantages of traditional construction lifting devices,a multi-station intelligent lifting device was developed and its key technology and product performance were researched.The specific research operations and effective results are stated bellow:1)Based on the work requirements,the relevant parameters of the multi-station intelligent lifting equipment were clarified.Preliminarily determine the overall plan of the multi-station intelligent lifting device and finish it with Solidworks software.2)Combined with relevant case explanations at the finite element level,using Static Structural module to obtain the static simulation results of the car,hoisting frame,rack support structure of lifting device in the multi-station intelligent lifting device.3)To improve the dynamic performance of the device,the modal analysis of the rack and pinion,the hoisting frame and the car hoisting device when the car is in different positions of the guide rail under no-load and full-load conditions are carried out.The natural frequency of the improved car frame structure avoids the excitation frequency and avoids resonance.This process makes it clear that the load of the car has a direct effect on the modal response of the system,and the position of the car is an indirect effect.4)Through the transient dynamic analysis of the multi-station hoisting platform to obtain the velocity-time response and acceleration-time response hypotaxis of the overall structure during the lifting phase,which proves that the lifting process is stable and safe.5)Using ANSYS Workbench to complete the topology optimization of the guide rail frame and the parameters optimization of the bottom support bracket of the lifting frame.The optimized mass,maximum equivalent stress and maximum deformation have been reduced by 3.2%,17.4% and 25.2% respectively.The researched multi-station intelligent lifting device has been trial-produced,and the related data can provides a reference for the subsequent applications of such devices.Figure 68;Table 19;Reference 59...
