When the vertical fin dock adopts the working platform, the overall position of the vertical fin dock is firstly adjusted to ensure that the working platform gradually moves to the maintenance part on the upper surface of the aircraft tail cone when the aircraft is maintained, and the working platform is in an initial horizontal state.

After the adjustment of the overall position of the vertical tail dock is finished, firstly, the driving motor 7 is started, the turbine shaft of the worm gear reducer 8 is driven to rotate through the driving motor 7, then the lead screw 9 is driven to rotate, the rotary motion of the lead screw 9 is directly converted into the linear motion of the screw 10, and the linear motion of the screw 10 finally drives the inner sleeve 6 to gradually extend downwards, along with the downward extension action of the inner sleeve 6, the movable section platform 2 gradually changes from a horizontal state to an inclined state until the inclination angle of the movable section platform 2 is the same as that of the upper surface of the tail vertebra of the airplane, at the moment, the driving motor 7 can be closed, and the movable section platform 2 is kept in the inclined state.

For the movable section platform 2 in an inclined state, a maintenance worker walks on the movable section platform 2 and can take care of all maintenance positions on the upper surface of the aircraft tail cone at one time, so that maintenance time is effectively saved, and maintenance efficiency is greatly improved.
