The invention discloses a side push cover sealing structure which comprises a side push cover body, a rotating shaft, a shaft hub, a rotating handle and a sealing seat, the shaft hub is welded and fixed to a ship bulkhead, the first end of the shaft hub is located on the inner side of the ship bulkhead, the second end of the shaft hub is located on the outer side of the ship bulkhead, the rotating shaft is arranged in the shaft hub in a penetrating mode, and the inner side end of the rotating shaft is fixedly connected with the rotating handle; the outer side end of the shaft hub is fixedly connected with the side push cover body, the sealing seat is fixed to the first end of the shaft hub and forms rotary sealing with the rotating shaft, an inflation sealing ring is arranged in an air gap between the shaft hub and the rotating shaft and located in the axial front of the sealing seat, and an inflation pipe is led out of the inflation sealing ring. And an air gap between the shaft hub and the rotating shaft is temporarily sealed. According to the side push cover sealing structure, by arranging the inflatable sealing ring, when a sealing fault occurs, the inflatable sealing ring can be expanded to serve as temporary sealing, the sealing seat on the inner side is convenient to disassemble, a ship can be maintained without being docked, manpower and financial resources are saved, and the maintenance cost is low.
本发明公开了一种侧推盖密封结构,其包括侧推盖本体、转动轴、轴毂、转动柄和密封座,轴毂焊接固定于船体舱壁上,且轴毂的第一端位于船体舱壁的内侧,第二端位于船体舱壁的外侧,转动轴穿设于轴毂中,且转动轴的内侧端与转动柄固连,外侧端与侧推盖本体固连,密封座固定于轴毂的第一端并与转动轴形成旋转密封,轴毂与转动轴的气隙中且位于密封座的轴向前方设置有充气密封圈,充气密封圈上引出有充气管,当充气密封圈膨胀时,对轴毂与转动轴的气隙形成临时密封。上述侧推盖密封结构通过设置充气密封圈,当密封故障时,可以使充气密封圈膨胀作为临时密封,方便拆卸内侧的密封座,实现船舶不进坞即可维修,节省人力、财力,维修成本低。
