The invention discloses a method for quickly centering an upper tower drum and a lower tower drum during hoisting of a large fan, which belongs to the technical field of fan mounting and comprises the following steps: S1, mounting a stiffening ring on the top of the mounted lower tower drum, and mounting a plurality of arc-shaped high-elastic steel bars on the stiffening ring at equal intervals in the circumferential direction; s2, elastic buttons are installed, specifically, the elastic buttons are installed in a plurality of top flange holes formed in the circumferential direction of the top face of the lower section tower drum; s3, the upper section of tower drum is hoisted, and the bottom of the upper section of tower drum is located among the multiple arc-shaped high-elasticity steel bars; s4, the upper section of tower drum is centered, and flange holes in the bottom of the upper section of tower drum are aligned with the multiple elastic buttons on the lower section of tower drum; and S5, the upper section of tower drum and the lower section of tower drum are fixed. According to the rapid centering method for the upper and lower sections of tower drums in large fan hoisting, the structure is simple, use is convenient, rapid centering of the upper and lower sections of tower drums is facilitated, and therefore the installation efficiency of a fan is improved.

    本发明公开一种大型风机吊装中上下节塔筒快速对中方法,属于风机安装技术领域,包括以下步骤:S1、在已安装的下节塔筒顶部安装加劲环,在加劲环上周向等间隔安装多个弧形高弹钢条;S2、安装弹性按钮,在下节塔筒顶面周向设置的多个顶部法兰孔中安装弹性按钮;S3、吊装上节塔筒,并使上节塔筒的底部位于多个弧形高弹钢条之间;S4、对上节塔筒进行对中,并使上节塔筒的底部法兰孔与下节塔筒上的多个弹性按钮分别对齐;S5、将上节塔筒与下节塔筒进行固定。本发明的大型风机吊装中上下节塔筒快速对中方法,结构简单,使用方便,便于对上下节塔筒快速对中,从而提高风机的安装效率。
