[0018] When using the fuselage dock provided with multiple lifting platforms of the present utility model to repair or maintain an aircraft, the aircraft is parked at the target position so that the fuselage dock main body 1 is located on both sides of the fuselage. When operations need to be performed at different height positions of the fuselage, the corresponding lifting platform 2 is driven to lift by the lifting drive assembly. Each lifting column 6 of the lifting platform 2 slides up and down under the limiting action of the guide wheels 7 of the guide wheel assembly. After reaching the target position, the screw 14 is rotated outward from one end, and the length of the screw 14 between the fixed jaw 12 and the movable jaw 13 is reduced. The fixed jaw 12 is fixedly arranged, and the movable jaw 13 swings towards the direction of the fixed jaw 12 to clamp the lifting column 6 therebetween, realizing the fixation of the position of the lifting column 6, that is, realizing the fixation of the position of the lifting platform 2, and subsequent processing operations can be carried out.
