Screw-in hanging structure with interchangeable hanging tools

The invention belongs to a component in a pile of a reactor, and particularly relates to a screw-in hanging structure with interchangeable hanging tools. The screw-in hanging structure has the following structural form that a petal type screw-in hanging hole with single-layer load bearing teeth is formed in the circumference of a flange of a hung element, the lower part of the hanging hole is a round hole, the upper part of the hanging hole is a petal-shaped hole, a hanging rod positioning hole is formed in the center position of the hanging hole, and a hanging rod position limiting hole is formed in the flange surface beside the hanging hole. One, two or three hanging structure(s) can be uniformly arranged on the circumference of the flange of the hung element according to requirements. The screw-in hanging structure can realize the interchange of hanging rods, and has the advantages that the occupied space is small, the structure is simple, the manufacturing cost is low, and the use is reliable.
