The invention relates to a pneumatic automatic unhooking hanging bracket for tonnage bags. The pneumatic automatic unhooking hanging bracket comprises an upper hanging bracket body and a lower hanging bracket body. The upper hanging bracket body is connected with one end of a steel wire rope gear, and the other end of the steel wire rope gear is connected with a crane. The pneumatic automatic unhooking hanging bracket is characterized in that the upper hanging bracket body and the lower hanging bracket body are connected through oil cylinders, and the lower hanging bracket body is provided with hooks; a control block is arranged in the middle of the lower hanging bracket body and provided with an energy accumulator through a connector; and the control block is connected with a first pipeline and second pipelines, the first pipeline is connected with lower openings of the oil cylinders, and the second pipelines are connected with the hooks. A two-position and two-way electromagnetic valve is arranged in the control block. The energy accumulator is composed of an oil liquid part and a gas part. Oil liquid is communicated with the first pipeline, the gas part is communicated with an inlet of the two-position and two-way electromagnetic valve, and an outlet of the two-position and two-way electromagnetic valve is connected with the second pipelines. By means of the pneumatic automatic unhooking hanging bracket for the tonnage bags, the problem that during traditional tonnage bag hanging bracket operation, the hooks need to be manually picked off is solved.
