Auxiliary tool for assembling transformer hanging core

The utility model relates to an auxiliary tool for assembling a transformer hanging core. At present, in the hoisting process of a transformer hoisting core, the hoisting core shakes in the hoisting process, and meanwhile, a bolt rod can penetrate into the hoisting core after a press-fit upper cover plate on the hoisting core is completely overlapped with a mounting hole in an apron board on an oil tank, so that the difficulty is brought to the assembly of the hoisting core. The transformer hanging core assembling auxiliary tool comprises an insertion pipe (1) and a spring buckle (5), the top of the insertion pipe is connected with a limiting baffle (2), the inner pipe wall of the insertion pipe is transversely connected with a hanging rod (3), the spring buckle is hung on the hanging rod and connected with one end of a pull rope (6), and a metal tension band (7) is fixed to the other end of the pull rope. The limiting baffle is of a circular steel plate structure, a pull rod (4) is connected to the circle ce
