摘　　要：门座架是由不等厚钢板焊接而成的大型构件,且处于斗轮堆取料机体下部,起到行走机构与上面部件的连接作用,同时还起到承受上面部件重力的作用。因此,门座架组装及焊接质量的好坏直接关系整机的安全性。通过分析某臂架型斗轮堆取料机四支腿门座架结构及使用特点,重点分析讨论了该结构在制造过程中的组装、焊接工艺及关键部位的质量控制。分析表明,该工艺可有效地控制结构的焊接变形,保证焊接质量,为门座架的生产制造提供借鉴与参考。Portal frame,which is under bucket-wheel stacker reclaimer,is a large frame structure welded in different thickness steels. It can connect walking mechanism with upper units and sustain weight from upper units. So the assembling and welding quality of it will influence the safety of device. In this paper,reasonable assembling,welding technology and method of quality control for main unit in manufacture process to four leg portal frame were summed up according to the features of using and the structure of portal frame in a wall frame type bucket-wheel stacker reclaimer. Analysis has proved that the reasonable welding technology may control effectively the deformation of welding,ensure the quality of welding and can provide experience for the production of other device.
