The invention relates to an assembling process for an upper trolley frame and a lower trolley frame of a rail-mounted gantry crane. The trolley frame is divided into an upper main frame and a lower rotary trolley frame; the upper main frame and the lower rotary trolley frame are fixed through a rotary support; the installation effect of the slewing bearing is guaranteed by controlling the installation mode and the installation precision of the slewing bearing on the lower slewing trolley frame; then, the assembling mode and the assembling precision between the upper main frame and the lower rotary frame are controlled, and the overall assembling effect and the assembling efficiency are guaranteed; by adopting the mode that the slewing bearing is firstly installed inside, and then the upper main frame and the lower slewing trolley frame are spliced outside, the assembly efficiency and the assembly accuracy of the rail-mounted gantry crane are greatly improved.
本发明涉及一种轨道吊上下小车架拼装工艺,小车架分为上主车架和下回转小车架;上主车架和下回转小车架之间采用回转支承固定;先通过控制回转支承在下回转小车架上的安装方式和安装精度,保证了回转支承的安装效果;然后控制上主车架与下回转车架之间的拼装方式和拼装精度,保证了整体的拼装效果和拼装效率;采用这种先内部安装回转支承,再外部拼接上主车架和下回转小车架的方式,极大了提高了轨道吊的拼装效率和拼装精确度。
