摘　　要：针对大通河特大桥节段拼装造桥机的高位拼装与节段梁高空吊运,设计了高位提升大型固定式龙门吊主体结构,以及可纵移主梁和两两串联的4台卷扬机结构天车,建立固定式龙门吊有限元分析模型对结构的反力、应力、刚度、稳定性进行验算,阐述了固定龙门吊高位拼装工艺,为类似龙门吊的设计与应用提供参考。Aiming at the high assembling and segmental beam overhead crane of bridge fabrication machine for precast segment bridge over Datong River,the main structure of high upgrade large fixed gantry crane and 4 hoist-style overhead traveling cranes which are installed with longitudinal shift beam and connected one by one are designed,then fixed-gantry-crane finite element analysis model is established to check the reaction force,stress,stiffness and stability of the structure,and finally the fixed gantry high assembly process is expounded,providing reference for the design and application of similar gantry crane.
