Assembling and Welding Technology of Four Leg Portal Frame to Wall Frame Type Bucket-Wheel Stacker Reclaimer
WANG Jing;Industrial Technology Center,Chengde Petroleum College;
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.
