The invention relates to a hoisting method for a generator stator of a thermal power generating unit. The hoisting method comprises the steps of preparation work, parallel operation of a crane, assembly, work before hoisting and generator stator installation. The crane is adopted for load bearing, a modern construction method is combined, the pulley block working principle is utilized, and the force of a hoisted object is changed. In the hoisting process, the moving posture and stress distribution of a structural member can be controlled, the structural member can be detained in the air for along time and adjusted slightly, inverted construction and air splicing are achieved, construction tasks difficult to complete by manpower and existing equipment are completed, the hoisting installation process of large components is simple, convenient, rapid, safe and reliable, meanwhile, civil construction of a steam turbine room and installation of steam turbine equipment are not influenced, the construction period is greatly shortened, the construction cost is reduced, and great economic benefits and social benefits are created for enterprises.
本发明是一种火电机组发电机定子吊装方法,其步骤包括:准备工作、行车并车、组装、吊装前工作和安装发电机定子。本发明采用行车承重、结合现代施工方法,利用滑轮组工作原理,改变吊装物体力的大小。在提升过程中,不但可以控制结构件的运动姿态和应力分布,还可以让结构件在空中长期滞留和进行微动调节,实现倒装施工和空中拼接,完成人力和现有设备难以完成的施工任务,使大型构件的起重安装过程既简便快捷,又安全可靠,同时没有影响汽机房土建施工和汽机设备安装,大大的缩短了施工工期,降低了施工成本,为企业创造了较大的经济效益和社会效益。
