一种大型球罐内部检修工作台的设计与分析
Design and analysis of an interior overhaul workbench of large spherical tank
摘要
Abstract
So far,the overhaul of large spherical tank is carried out by building an all-round scaffold in most cases.However,there are many problems in this way,such as high labor intensity,long overhauling period,poor safety,and easy to cause secondary damage and so on.In order to solve problems mentioned above,an interior overhaul workbench of large spherical tank was designed.The workbench consisted of a bottom supporting platform,a central supporting column,a revolving sup-porting platform,a top revolving platform and pulling devices.What's more,it combined a kind of bidirectional traction from the top and bottom and a revolving motion from the top,w hich ensured manned workbasket could be delivered to all the overhauling spots quickly and accurately.The man-ned workbasket,central supporting column and both of the top and bottom revolving supporting arms formed a four-bar mechanism to ensure the manned workbasket remained horizontal throughout the travelling process.In order to verify the reasonability of this workbench,simulation analysis of dynamics and statics was done by MATLAB and ADAMS.The result showed that this workbench met the requirements of bearing capacity,stability and safety.With a simple structure,handling fa-cility,the overhaul workbench is powered by electricity,which is easy to monitor.Therefore,this overhaul workbench will greatly improve the working efficiency of overhauling large spherical tank.关键词
