一种悬臂式检修平台的设计

Design of a Cantilever Type Maintenance Platform

车身厂装焊车间某车型顶盖生产线提升设备配重系统安装于二层钢结构平台,平台面积较小,配重系统自身高度较大,日常维保时需支立人字梯辅助作业,检修作业效率低下,作业风险多。为解决现场维保作业条件困难问题,需为配重系统增设检修平台。根据现场工况及作业空间限制,检修平台采用悬臂式设计。为避免焊接对配重系统钢结构产生热影响,检修平台和配重框架采用摩擦副连接。为保证安全性和可靠性,强度校核完毕后,再在现场实施。

In the company's welding workshop,a lifting equipment counterweight system is mounted on the second-story steel platform with a limited space and a larger height.A herringbone ladder always be used during daily maintenance and repairing works.It caused low efficiency of maintenance work and high operational risks.In order to improve on-site working conditions,it is necessary to add an overhaul platform for the counterweight system.According to site conditions and the limited working space,the platform adopts a cantilever design.The maintenance platform is fastened onto the counterweight frame by friction pairs to avoid the thermal effect of welding.Strength check must be done before on-site implementation in order to ensure safety and reliability.
