The invention relates to a through-flow rotor hoisting tool. The upper ends of a hoisting plate a and a hoisting plate b are fixedly connected through two supporting rods, the lower ends of the hoisting plate a and the hoisting plate b are fixedly connected through two studs, the two studs penetrate a rotor bracket, and two ends of the studs are fixedly connected to the hoisting plate a and the hoisting plate b through nuts. The outer diameter of an arc plate is determined according to the inner diameters of flanges at two ends of the rotor bracket and the arc plate is welded to the inner sides of the hoisting plate a and the hoisting plate b, separately, supporting blocks are symmetrically welded to the inner side of the hoisting plate b left and right, and reinforcing rings are welded totwo ends of hoisting holes in the hoisting plate a and the hoisting plate be. The hoisting tool solves the problems that it is needed to detach a plurality of magnetic poles and connecting wires before the rotor is hoisted and mount the detached magnetic poles and connecting wires again after the rotor is mounted, and the rotor cannot be hoisted as the rotor is higher than the rotor bracket afterthe connecting wires are mounted. The hoisting tool is simple to manufacture, compact in structure, convenient to mount and firm and stable to hoist the rotor. The hoisting tool is of very high practicality.
一种贯流转子起吊工具,起吊板a和起吊板b的上端通过两个支撑杆固定连接,起吊板a和起吊板b的下端通过两个双头螺柱固定连接,两个所述双头螺柱穿过转子支架,双头螺柱的两端通过螺母与起吊板a和起吊板b固定连接;根据转子支架两端法兰内径确定弧板的外径,并分别焊于起吊板a和起吊板b的内侧,支撑块分左、右对称焊于起吊板b的内侧,加强环焊于起吊板a、起吊板b中起吊孔两端。此起吊工具解决了转子起吊前需拆下多个磁极及连接线,转子安装后再将拆下的磁极及连接线安装上所带来的困难,并解决了连接线安装后高出转子支架无法起吊的问题。此起吊工具制作简单,结构紧凑,安装方便,起吊转子牢固平稳。具有很强的实用性。
