摘要
针对活塞杆支撑横向负载较大,造成支座支撑能力弱、使用寿命短的问题,设计了适用于化工设备的气缸支座和滚轮支座。在气缸支座结构加设两块垫铁和两个滑道,在塔体安装弹簧气缸支座,选取当地的仪表空气、压缩空气或密封氮气等引入气缸支座中;在滚轮支座上设置推力支架和下机架,根据滚轮的位移调整开槽长度,通过滚轮支座的运动方向设计滚轮的运动方向。最后将设计的支座数据导入三维建模软件Pro/E中构建三维模型,完成气缸支座和滚轮支座的优化设计。实验结果表明,加入气缸支座和滚轮支座后的化工设备,倾覆力矩与理论计算结果基本相同,支撑能力更强,运行更稳定,使用寿命更长。
The large transverse load of piston rod support results in weak support capacity and short service life of the support.Aiming at above problem it designs the cylinder support and roller support for chemical equipment.The design adds two sizing blocks and two slide ways in the cylinder support structure,installs the spring cylinder support in the tower body,selects local instrument air or the compressed air to introduce into the cylinder support,and calculates the cylinder piston area.The thrust support and the lower frame are set on the roller support,and the slotting length is adjusted according to the displacement of the roller.The movement direction of the roller is designed through the movement direction of the roller support,and the designed support data is imported into the 3D modeling Pro/E system to build the 3D model and complete the optimal design of the cylinder support and the roller support.The experimental results show that the overturning moment of the chemical equipment with cylinder support and roller support is basically the same as the theoretical calculation results with stronger support capacity,more stable operation and longer service life.
