A superlift on-load walking and lifting method for a large crawler crane in coke oven transformation engineering is characterized by comprising the following steps: a, selecting the crawler crane according to the distance between a slide wire and a coke oven, the lifting capacity, the lifting radius, the lifting height, the size of a single-truss main truss component and the gravity center of the component, b, assembling a greenhouse main steel truss section between the outer side of the slide wire and a vestibule, and c, assembling a main steel truss section between the outer side of the slide wire and the vestibule. D, the crawler crane is driven to a standing point; e, the main truss is lifted to move towards the east by a certain distance; f, the end table crawler crane and the intermediate table crawler crane lift the main truss to move; g, rotating arms of the two crawler cranes are adjusted; and j, the lifting radius of the 800t crawler crane of the spacing platform is 18m. The method has the advantages that the main truss is assembled, the coke oven production is not influenced, and the coke oven maintenance site and time requirements are met.
一种焦炉改造工程大型履带吊超起带载行走抬吊方法,其特征在于包括以下步骤:a、根据滑线与焦炉之间的距离,起重量、吊装半径、起吊高度、单榀主桁架构件尺寸、构件重心选择履带吊,b、大棚主钢桁架分段在滑线外侧与通廊之间拼装,c、履带吊行走区域地基处理,d、履带吊开至站位点,e、将主桁架抬吊向东平移一定距离,f、端台履带吊,间台履带吊抬吊主桁架行走,g、两台履带吊转臂调整,h、使端台履带吊到达增加超起配重位置,i、采用两台辅助吊车增加端台履带吊超起配重,j、间台800t履带吊采用18m吊装半径。本发明具有主桁架拼装,不影响焦炉生产,满足焦炉检修场地和时间要求的优点。
