Self-expansion type stator hanging tire

The utility model relates to a self-expansion type stator hanging tire which comprises a pull rod, wherein a fixed sleeve is located at the lower part of the pull rod through a fastening member, a sliding sleeve is installed at the upper part of the pull rod through a limit pin, the pull rod at the upper part of the sliding sleeve is sleeved with a spring, a hanging ring is installed at the top of the pull rod, three installing members are respectively uniformly distributed on the outer circumferential surfaces of the fixed sleeve and the sliding sleeve, the head parts of the installing members located in the same vertical plane are connected with support rods through connecting sheets, and the end parts of the three vertical support rods are on the same circumferential surface. The self-expansion type stator hanging tire is compact and reasonable in structure; by using a hinge mechanism and a self-locking mechanism, the inner diameter of a stator can be expanded conveniently by the hanging tire, and then the winding stator is hung to a base through a crane or balance crane.
