[0021] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Figure 1 An embodiment of the utility model provides a high-speed UAV single-side beam central axis rolling operation storage and transportation frame, including: an operation frame 10, two adjustable brackets 21 components 20 and a lifting drive mechanism 30.

[0022] A pulley assembly 11 is provided at the bottom of the work frame 10 to facilitate the movement of the work frame 10 .

[0023] Two adjustable bracket 21 assemblies 20 are respectively arranged on both sides of the working frame 10 for supporting the single-side beam center axis of the high-speed UAV. The adjustable bracket 21 assembly 20 includes a bracket 21 and a plurality of directional pulley assemblies 22. The bracket 21 can be lifted and lowered on the working frame 10. A bracket 23 is arranged on the bracket 21. The directional pulley assembly 22 is rotatably arranged in the bracket 23. A plurality of directional pulley assemblies 22 are arranged in sequence from one end to the other end of the bracket 23. The single-side beam center axis of the high-speed UAV is placed in the two brackets 23 and supported by the directional pulley assembly 22. At this time, the directional pulley assembly 22 is roughly arranged around the axis of the single-side beam center axis of the high-speed UAV. When the single-side beam center axis of the high-speed UAV needs to roll to adjust the angle, there is rolling friction between the directional pulley assembly 22 and the single-side beam center axis of the high-speed UAV. Therefore, the force required for the staff to drive the single-side beam center axis of the high-speed UAV to rotate is small, which is convenient for the staff to operate, and can also reduce the friction on the single-side beam center axis of the high-speed UAV to avoid scratching the single-side beam center axis of the high-speed UAV.

[0024] See also Figure 2 and Figure 3 The lifting drive mechanism 30 is connected to the bracket 21 for driving the bracket 21 to lift and lower the bracket 21, thereby adjusting the height of the two brackets 21 so that the heights of the two brackets 21 match each other, thereby preventing the single-side beam center axis of the high-speed UAV from tilting and sliding out of the bracket 21 during storage and transportation.

[0025] In some optional embodiments, a work platform 12 is provided on the work frame 10, and the work platform 12 is located on one side of the adjustable bracket 21 assembly 20. The work platform 12 is provided for the staff to stand close to the central axis of the single-sided beam of the high-speed UAV on the bracket 21, so as to facilitate the staff to carry out work processes such as loading, inspection, debugging, and maintenance.

[0026] The lifting drive mechanism 30 can be designed according to actual needs. For example, the lifting drive mechanism 30 can adopt a screw drive assembly, a rotary motor drive assembly, a cylinder translation drive assembly or a linear motor translation drive assembly, etc. In some optional embodiments, the lifting drive mechanism 30 includes a lifting rod 31 and a rotating handle 32. The lifting rod 31 can be lifted and lowered on the work frame 10. The top of the lifting rod 31 is connected to the bracket 21. The rotating handle 32 is rotatably set on the work frame 10 and is drivingly connected to the lifting rod 31. A rack can be set on the lifting rod 31, and a gear meshing with the rack is set on the rotating handle 32. When the rotating handle 32 is rotated, the lifting rod 31 can be driven to rise and fall through the rack belt; or, the lifting rod 31 is a screw rod, the lifting rod 31 is threaded with the frame, and the rotating handle 32 drives the lifting rod 31 to rotate directly, thereby causing the lifting rod 31 to rise and fall relative to the frame.

[0027] In some optional embodiments, a guide sleeve 13 is provided on the work frame 10, and the lifting rod 31 is movably inserted into the guide sleeve 13. The guide sleeve 13 guides the lifting rod 31 to rise and fall, thereby improving the stability of the lifting.

[0028] In some optional embodiments, a plurality of limit portions 14 are provided on the work frame 10 and are located on both sides of the bracket 23. The limit portions 14 extend upward away from the work frame 10. The limit portions 14 limit both sides of the portion where the center axis of the single-sided beam of the high-speed drone is higher than the bracket 23, thereby preventing the center axis of the single-sided beam of the high-speed drone from detaching from the bracket 23.

[0029] In some optional embodiments, two guide rails 15 are provided on the work frame 10 , and the bracket 21 slides with the guide rails 15 . The guide rails 15 guide the bracket 21 to rise and fall stably, thereby improving the stability of the bracket 21 .

[0030] In some optional embodiments, the guide track 15 includes two slide grooves, which are respectively located on both sides of the bracket 21. The bracket 21 slides with the slide grooves, and the two slide grooves cooperate to guide the bracket 21, so that the bracket 21 can be lifted more stably, and it is also prevented that the bracket 21 is easy to shake left and right after the middle axis of the single-side beam of the high-speed drone is placed in the bracket 23. In this embodiment, the slide groove is set on the limit part 14.

[0031] In some optional embodiments, the pulley assembly 11 includes a plurality of heavy-duty universal shaft pulleys disposed at the bottom of the work frame 10 . The heavy-duty universal shaft pulleys can stably support the work frame 10 and facilitate the flexible movement of the work frame 10 .

[0032] In some optional embodiments, a plurality of straight support rods 24 are provided on the bracket 21, and the straight support rods 24 surround and form a bracket 23. This design makes it easier to form the structure of the bracket 21 and avoids the need to add a curved structure.

[0033] Since the outer side of the middle axis of the single-side beam of the high-speed UAV is a curved surface, and the inner wall of the bracket 23 is a straight line, in order to make the position of the directional pulley assembly 22 adapt to the shape of the middle axis of the single-side beam of the high-speed UAV, the multiple directional pulley assemblies 22 include multiple large directional pulley assemblies 221 and multiple small directional pulley assemblies 222, and the large directional pulley assemblies 221 and the small directional pulley assemblies 222 are together formed around a support space, and the shape of the support space is adapted to the shape of the middle axis of the single-side beam of the high-speed UAV, and the multiple large directional pulley assemblies 221 and the multiple small directional pulley assemblies 222 cooperate to stably support the middle axis of the single-side beam of the high-speed UAV, avoiding the situation that the middle axis of the single-side beam of the high-speed UAV cannot be stably supported due to the shape of the bracket 23. The large directional pulley assembly 221 is mainly arranged at a position close to the corners of the bracket 23, avoiding the directional pulley assembly 22 being far away from the middle axis of the single-side beam of the high-speed UAV and unable to contact the middle axis of the single-side beam of the high-speed UAV due to the relationship between the corners of the bracket 23.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
