Background

In the process of assembling airplane wing components, wings are often required to be turned over (upper and lower wing surfaces are turned over), and the existing wing turning scheme is as follows: the lifting rope is connected with the intersection hole of the wing, and the bottom of the wing leans against the bracket to turn over. In the turning process, the ropes can not be pulled too tightly by the hanger and the ropes in the turning process of the wing, if the ropes are too tight, the wing can be pulled by the ropes to move horizontally, relative movement between the wing and the bracket can be caused, and the wing and the bracket even fall out of the bracket. In order to prevent the wing from moving horizontally along with the rope, the rope needs to be loosened when the wing is in a state of being vertical to the ground, so that the wing can perform overturning movement around the bracket supporting axis. In the process of releasing the rope, the wings are not under the tension action of the rope, are in a free-falling state and have potential safety hazards. And the momentum created when the rope falls freely can cause damage to the wing when the rope is again tightened.
