However, the supporting tool lacks a movable supporting tool for the belly position, so that the patent still has the following defects: during the transfer, the supporting and transferring effect of the airplane is poor, and in addition, the requirement of operation at the belly part cannot be met.
A group of supporting frames are generally distributed at the bottom of the belly of the airplane from beginning to end, so that a movable supporting platform of the belly can be designed by utilizing the group of supporting frames to meet the requirements.
In addition, in order to improve the assembly efficiency and precision of the airplane, a station type assembly production line is mostly adopted for the assembly of the airplane at present, and the airplane completes the assembly task of each stage by transferring among different stations.
