The invention provides a microgravity unfolding device and relates to the technical field of active microgravity unfolding of complex space mechanisms. The microgravity unfolding device comprises a portal frame, a servo elevator assembly and a hanging structure. The servo hoister assembly is mounted at the top of the portal frame, and the servo hoister assembly follows the movement while balancing the weight of the measured object; the hanging structure comprises a steel wire rope, a movable pulley, a mass center leading-out hanging structure and a whole wing hoisting frame, the steel wire rope is hoisted along with the servo hoisters, the steel wire rope is wound on the movable pulley, the two servo hoisters are subjected to the same stress through rolling of the movable pulley, and the bottom of a supporting frame of the movable pulley is connected with the mass center leading-out hanging structure. The mass center leading-out hanging structure is connected to the whole wing lifting frame through the two-dimensional adjusting rotating shaft, and the whole wing lifting frame is connected with a measured object. The device can effectively solve the problem of ground simulation expansion of a large-load mechanism of a certain space station, and has the functions of large-load gravity balance, follow-up movement and the like.
