The invention discloses a segmented hoisting device and method for a feeding skew bridge of a blast furnace, and the device comprises a crane, a first feeding skew bridge section and a second feeding skew bridge section, a furnace top temporary support is arranged at the joint of the upper end of the first feeding skew bridge section and the blast furnace top, and a furnace body temporary support is arranged at the lower end; a lower fulcrum is arranged at the bottom of the second feeding skew bridge section and comprises a supporting plate arranged at the bottom end of the second feeding skew bridge section, a supporting base, an adjusting wheel arranged on the supporting base and an adjusting cylinder arranged on the supporting base; a joint tongue-and-groove and an inclined strut inlaying section are arranged at the joint of the first feeding skew bridge section and the second feeding skew bridge section, the feeding skew bridge is divided into two sections, and the two sections of the feeding skew bridge are separately hoisted. The two sections of feeding skew bridges can be hoisted only through one crane, the feeding skew bridges do not need to be manually monitored and adjusted in the high altitude in the hoisting process, and the feeding skew bridges at the two ends are directly conveyed to an installation site after being prefabricated in a factory.

    本发明公开了一种高炉上料斜桥分段吊装装置及方法,装置包括:吊机,还包括第一上料斜桥段以及第二上料斜桥段;所述第一上料斜桥段上端与高炉炉顶的连接处设有炉顶临时支撑,下端设有炉身临时支撑;所述第二上料斜桥段底部设有下支点,该下支点包括设于所述第二上料斜桥段底端的支撑板、支撑底座、设于所述支撑底座上的调节轮以及设于所述支撑底座上的调节缸;所述第一上料斜桥段与第二上料斜桥段的连接处设有接头企口与斜撑嵌补段,将上料斜桥分为两段,对两段上料斜桥分开进行吊装。两段上料斜桥均仅需使用一台吊机进行吊装即可,且吊装过程中不需要人工在高空中对上料斜桥进行监测以及调整,且两端上料斜桥在工厂预制后直接运送至安装场地。
