The invention relates to a manhole structure for the top of a reaction vessel, which comprises a manhole main body mechanism, a davit mechanism and a connecting mechanism, the manhole main body mechanism comprises a shell ring, a flange and a flange cover, and the davit mechanism comprises an upper support plate, a lower support plate, a reinforcing plate, a davit seat, a davit, a lower sealing plate, a liner tube and a cover plate. The connecting mechanism comprises a hanging plate, a turnbuckle and a hanging ring, the hanging plate is fixedly connected with the upper end of the hanging column, the turnbuckle comprises an upper screw rod, a lower screw rod and a spiral sleeve, the top of the upper screw rod is provided with an upper connecting joint which is connected with the hanging plate, the bottom of the lower screw rod is provided with a lower connecting joint which is connected with the hanging ring, and the spiral sleeve is connected with the hanging plate. The lifting ring is fixedly connected with the flange cover, a first mounting seat is arranged on the lifting column, a second mounting seat is arranged on the flange cover, and the first mounting seat and the second mounting seat are connected through a connecting piece, so that the phenomenon that the sealing surface of a flange is abraded due to the fact that the flange cover shakes in the lifting process can be prevented.
