The one end of the first horizontal moving frame and the one end of the second horizontal moving frame can slide up and down relative to the fixed ladder. Since the horizontal moving frame is movably connected with the fixed ladder and the horizontal moving frame is movably connected with the wave-compensated gangway, the emergency evacuation device can adapt to the relative movement between the fixed ladder and the wave-compensated gangway in the case of failure of the wave-compensated gangway, reliably connects the fixed ladder and the wave-compensated gangway, and enables the personnel on the wave-compensated gangway to be transferred to the fixed ladder through the emergency evacuation device, thereby ensuring the safety of the personnel. Therefore, in the design, since the horizontal moving frame is movably connected with the fixed ladder and the horizontal moving frame is movably connected with the wave-compensated gangway, the emergency evacuation device can adapt to the relative movement between the fixed ladder and the wave-compensated gangway in the case of failure of the wave-compensated gangway, reliably connects the fixed ladder and the wave-compensated gangway, facilitates the evacuation of personnel, and ensures the safety of the personnel.

When the wave-compensated gangway fails and the distance between the wave-compensated gangway and the fixed ladder is far, the personnel cannot approach the fixed ladder. At this time, the movable end of the movable truss is rotated to the wave-compensated gangway, and the personnel can walk on the movable truss and move to the fixed truss, and then move to the fixed ladder through the fixed truss.
