The invention relates to an airbag buoyant raft vibration isolation device of a ship double-engine double-propeller propulsion system. The device comprises a raft frame and two propulsion motors, the two propulsion motors are arranged side by side, the lower portions of the two propulsion motors are arranged on the upper surface of the raft frame through rubber vibration isolators, a vertical displacement adjusting air bag vibration isolator and a horizontal displacement adjusting air bag vibration isolator are arranged between the raft frame and a ship body base, a plurality of height sensors are arranged on the upper surfaces of the propulsion motors, a plurality of horizontal position sensors are arranged on the raft frame outside the two propulsion motors, a controller is used for adjusting the position of the raft frame by adjusting the inflation amount of the vertical displacement adjusting air bag vibration isolator and the horizontal displacement adjusting air bag vibration isolator according to detection results of the height sensors and the horizontal position sensors, and synchronous centering posture control over the two propelling motors is achieved. The system has the advantages of being good in vibration isolation effect, capable of achieving real-time high-precision centering attitude control, high in intelligent degree and the like, and can be used for achieving integrated efficient vibration isolation of a ship double-engine double-propeller propelling system.
