[0061] The second limiting fixing block 17 is provided on the side of the lifting limiting plate 14 away from the lifting thread section 13.

[0062] Both sides of the second limiting fixing block 17 are rotatably connected to connecting rods 16;

[0064] Working principle: This embodiment sets a lifting mechanism including a support shell, a top plate, a rotating shaft, a movable plate, a lifting thread section, a lifting limit plate, a first limit fixing block, a connecting rod and a second limit fixing block at both ends of the fixed platform and the fixed shell. The lifting mechanism cooperates with the fixed platform and the fixed shell to enable the flexible general aircraft support tooling to more stably support the maintenance of general aircraft when in use.

[0065] like Figure 3 、 Figure 4 、 Figure 5 As shown, the lifting mechanism includes a support shell 6, a top plate 7, a rotating shaft 11, a movable plate 12, a lifting threaded section 13, a lifting limit plate 14, a first limit fixing block 15, a connecting rod 16 and a second limit fixing block 17. The interior of the support shell 6 is rotatably connected to the rotating shaft 11. The interior of the support shell 6 is also equipped with a driving assembly for driving the rotating shaft 11 to rotate. The outer side of the top of the rotating shaft 11 is provided with a lifting threaded section 13.

The other end of the connecting rod 16 is rotatably connected to a first limit fixing block 15, and the first limit fixing block 15 is fixed to the support shell 6.

[0066] In this embodiment, the number of the lifting limit plates 14 is four. In other embodiments, the number of the lifting limit plates 14 can be designed and determined according to the required support strength.

[0067] Example 2:

[0068] This embodiment is based on the above embodiment 1. Figure 3 、 Figure 4 、 Figure 5 As shown, the drive assembly includes a lifting drive motor 8, a transmission worm 9 and a transmission worm gear 10. The lifting drive motor 8 is also fixed inside the support shell 6. The output end of the lifting drive motor 8 is connected to the transmission worm 9. One side of the transmission worm 9 is meshedly connected to the transmission worm gear 10, and the transmission worm gear 10 is fixed to the outside of the rotating shaft 11.

At the same time, the lifting and lowering of the lifting limit plate 14 is supported by the rotation connection between the connecting rod 16 and the first limit fixing block 15 and the rotation connection between the connecting rod 16 and the second limit fixing block 17. The lifting and lowering of the lifting limit plate 14 drives the slidingly connected top plate 7 to rise, and then the maintenance part of the general aircraft can be supported through the top plate 7 and the buffer pad on the top of the top plate 7.

[0070] The rest of this embodiment is the same as that of the above-mentioned embodiment 1, and therefore will not be described in detail.

[0071] Example 3:

[0072] This embodiment is based on any one of the above embodiments 1-2. Figure 1 、 Figure 2 As shown, a connecting assembly for connection is installed at one end of the fixed platform 1, and the connecting assembly consists of a first connecting block 2, a positioning card plate 3 and a second connecting block 4. The first connecting block 2 is fixed to the fixed platform 1, and the interior of the first connecting block 2 is detachably connected to the positioning card plate 3, so that one end of the positioning card plate 3 can be rotated on the inner side of the first connecting block 2, and the other end of the positioning card plate 3 is detachably connected to the second connecting block 4, and the second connecting block 4 is fixed to the fixed shell 5, so that the other end of the positioning card plate 3 can be rotated on the inner side of the second connecting block 4, so that the tooling can be positioned as a whole through the connection of the connecting assembly when in use;

[0073] The first connecting block 2 and the positioning card plate 3, as well as the positioning card plate 3 and the second connecting block 4 are connected by bolts, so that the positioning card plate 3 is limited on the inner side of the first connecting block 2 and the positioning card plate 3 is limited on the inner side of the second connecting block 4 by the connecting bolts, so that they can rotate;

[0074] In this embodiment, there are three connecting components. In other embodiments, the number of connecting components can be determined according to design requirements.

[0075] Among them, universal wheels are fixed at both ends of the bottom of the fixed platform 1 and the fixed shell 5, so that the tooling can be moved by the universal wheels when not in use;

[0076] Working principle: When in use, the positioning card plate 3 is fixed to the inner side of the first connecting block 2 by connecting bolts, and then the positioning card plate 3 is rotated according to the limit of the connecting screw plug, so that the positioning card plate 3 enters the inner side of the second connecting block 4, and the positioning card plate 3 and the second connecting block 4 are connected by connecting bolts, thereby pushing the support tooling and moving through the universal wheels at the bottom of the fixed platform 1 and the fixed shell 5.

[0077] The rest of this embodiment is the same as any of the above embodiments 1-2, so it will not be repeated here.

[0078] Example 4:

[0079] This embodiment is based on any one of the above embodiments 1-3. Figure 6 、 Figure 7 、 Figure 8 As shown, a displacement adjustment mechanism is installed inside the fixed shell 5 for driving the lifting mechanisms at both ends of the top of the fixed shell 5 to move. The displacement adjustment mechanism includes a displacement drive motor 18, a moving member, a first transmission gear 20, a connecting shaft 21, a displacement threaded segment 22, a positioning plate 23, a rotation limit plate 24, a second transmission gear 25, a third transmission gear 26 and a connecting plate 27. The interior of the fixed shell 5 is slidably connected to the positioning plate 23. A moving member is fixed inside the fixed shell 5 at a position corresponding to the positioning plate 23, and the output end of the moving member is fixed to the positioning plate 23. The top of the positioning plate 23 is fixed with a displacement drive motor 18, so that the positioning plate 23 can drive the displacement drive motor 18 to move when it moves;

[0080] The output end of the displacement drive motor 18 is connected to a first transmission gear 20, and both sides of the first transmission gear 20 are meshed with third transmission gears 26. A connecting shaft 21 is fixed inside the third transmission gear 26, and a second transmission gear 25 is fixed outside the connecting shaft 21 and at one end of the third transmission gear 26. Therefore, the meshing of the first transmission gear 20 and the third transmission gear 26 or the meshing of the first transmission gear 20 and the second transmission gear 25 can drive one or both connecting shafts 21 to rotate.

[0081] The outer side of the connecting shaft 21 is also rotatably connected to a rotation limit plate 24, and the bottom end of the rotation limit plate 24 is fixed to the fixed shell 5, thereby supporting the connecting shaft 21 through the rotational connection between the connecting shaft 21 and the rotation limit plate 24. A displacement thread segment 22 is provided on the outer side of the connecting shaft 21 and at the end of the second transmission gear 25 away from the third transmission gear 26, and the thread rotation directions of the two displacement thread segments 22 are opposite. The outer side of the displacement thread segment 22 is threadedly connected to a connecting plate 27, and the top of the connecting plate 27 is fixed to the support shell 6, thereby enabling the support shell 6 to move by the movement of the connecting plate 27;

[0082] In this embodiment, the moving member is a cylinder 19. In other embodiments, the moving member may be a push rod motor, a hydraulic pump, or other mechanism capable of driving the positioning plate 23 to move.

[0083] Working principle: When a general aircraft is to perform maintenance on two wings, it is determined whether the maintenance positions of the two wings are symmetrical. When the maintenance positions are symmetrical, the displacement drive motor 18 is energized and driven to rotate the first transmission gear 20. The rotation of the first transmission gear 20 drives the third transmission gears 26 on both sides to rotate at the same time. The rotation of the third transmission gear 26 drives the connecting shaft 21 to rotate, and the rotating connecting shaft 21 is supported by the rotation connection between the rotating limit plate 24 and the connecting shaft 21. When the connecting shaft 21 rotates, it drives the displacement threaded section 22 to rotate. The two displacement threaded sections 22 with opposite thread rotation directions drive the threaded connecting plate 27 to move in the same or opposite directions. The movement of the connecting plate 27 drives the support shell 6 to move, thereby being able to move the jacking mechanism to the two symmetrical wing maintenance positions.

[0084] When the positions of the two wings for maintenance are asymmetrical, the positioning plate 23 is driven to move by the cylinder 19, and the positioning plate 23 is limited by the sliding connection between the positioning plate 23 and the fixed shell 5. The movement of the positioning plate 23 drives the displacement drive motor 18 to move, and the movement of the displacement drive motor 18 drives the first transmission gear 20 to move, so that the first transmission gear 20 is engaged with one of the second transmission gears 25. When the displacement drive motor 18 is energized and drives the first transmission gear 20 to rotate, the meshing connection between the first transmission gear 20 and one of the second transmission gears 25 drives one of the connecting shafts 21 corresponding to one of the second transmission gears 25 to rotate, and the rotation of one of the connecting shafts 21 drives the corresponding one of the displacement thread segments 22 to rotate, and the rotation of one of the displacement thread segments 22 drives the corresponding connecting plate 27 to move, thereby driving one of the lifting mechanisms to move to an appropriate position;

[0085] Then the cylinder 19 drives the displacement drive motor 18 to move, and the displacement drive motor 18 drives the first transmission gear 20 to engage with the other second transmission gear 25. When the displacement drive motor 18 is energized and drives the first transmission gear 20 to rotate, the meshing connection between the first transmission gear 20 and the other second transmission gear 25 drives the corresponding other connecting shaft 21 to rotate, and the rotation of the other connecting shaft 21 drives the corresponding other displacement thread segment 22 to rotate, and the rotation of the other displacement thread segment 22 drives the corresponding connecting plate 27 to move, thereby driving the other lifting mechanism to move to the appropriate position, thereby supporting the asymmetric position of the two wings for maintenance.

[0086] The rest of this embodiment is the same as any of the above embodiments 1-3, so it will not be repeated here.

[0087] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the scope of protection of the present invention.
