Holosymmetrical cable membrane reversed hanging structure synchronous rotation sealing system

The invention discloses a holosymmetrical cable membrane reversed hanging structure synchronous rotation sealing system which comprises a sealing cover, a circular track beam formed by a first holosymmetrical flange connection rectangular truss module and a second holosymmetrical flange connection rectangular truss module in flanged connection, a universal adjustable bearing wheel device, a middle exhaust pipeline, and a holosymmetrical motive seal centre gas collection device connected to the circular track beam, wherein the sealing cover is fixedly connected with the circular track beam; the sealing cover and the circular track beam rotate together with a mud scraper traveling crane in a round tank synchronously; the holosymmetrical motive seal centre gas collection device comprises a seal joint and a seal joint connecting base; the connection between the seal joint and the seal joint connecting base is a rotation connected relation of a rotating shaft and a rotating hole; a motive seal structure of a bulge embedded groove is arranged between the seal joint and the seal joint connecting base. According to the holosymmetrical cable membrane reversed hanging structure synchronous rotation sealing system, the service life is long; the cost is low; the sealing work is reliable; the installation cost and the maintenance cost are low.
