The auxiliary lifting device comprises a guide rail and a portal frame, a lifting set is arranged on the portal frame, the portal frame is arranged above the guide rail and can slide along the guide rail, a shell is arranged below the portal frame, a plurality of mounting grooves are formed in the shell, and a lifting set is arranged in the mounting groove. After the rotor is hoisted, the heights of the two first rack rods and the rolling wheels can be automatically adjusted through the adjusting sets according to the diameters of the two ends of the rotor, so that the two ends of the rotor can be resisted by the rolling wheels at the same time, and the two ends, with different diameters, of the rotor can be in a horizontal state; the horizontal positioning of the two ends of the rotor can be quickly completed, so that the blades on the rotor can be quickly aligned with the mounting grooves during hoisting, and the mounting work can be quickly completed.
本发明公开了汽轮机安装技术领域的一种汽轮机安装用辅助升降装置,包括导轨和龙门架,所述龙门架上设置有吊放组,所述龙门架设置于导轨的上方且能够沿着导轨滑动,所述龙门架下方设置有壳体,所述壳体内部开设有若干个安装槽,本发明,在将转子吊起之后,通过调节组能够自动地根据转子两端直径的大小来调节两个第一齿条杆和滚轮的高度,从而使转子的两端能够同时受到滚轮的抵制,进而使转子直径不同的两端能够处于水平的状态,能够快速地完成转子两端的水平定位,进而在吊放的时候转子上的叶片能够与安装槽快速地对齐,能够快速地完成安装工作。
