[0026] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following briefly introduces the drawings required for use in the description of the embodiments of the present invention. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on the contents of the embodiments of the present invention and these drawings without paying any creative work.

[0027] In one embodiment of the present invention, a high-altitude work boom, such as Figure 1 As shown, it includes: a turntable 1, a first drive motor 2, a first telescopic arm 3, a second drive motor 4, a drive sprocket 5, a telescopic drive chain 6, a driven sprocket 7, a second telescopic arm 8, a third drive motor 9, and a working bucket 10.

[0028] The fixed part of the first drive motor 2 is installed on the turntable 1, and the first telescopic arm 3 is installed on the rotating part of the first drive motor 2. Under the rotational driving force of the first drive motor 2, the first telescopic arm 3 can realize up and down amplitude movement.

[0029] The fixed part of the second driving motor 4 is mounted on the first telescopic arm 3 , and the driving sprocket 5 is mounted on the rotating part of the second driving motor 4 .

[0030] Furthermore, the driving sprocket 5 and the driven sprocket 7 are arranged at two ends outside the first telescopic arm 3, the driving sprocket 5 is arranged at one end close to the second driving motor 4, and the driven sprocket 7 is arranged at one end away from the second driving motor 4. The telescopic driving chain 6 is wound around the driving sprocket 5 and the driven sprocket 7. The telescopic driving chain 6 passes through the first telescopic arm 3, with a part on the outer side of the upper part of the first telescopic arm 3 and a part inside the first telescopic arm 3.

[0031] The second telescopic arm 8 is arranged inside the first telescopic arm 3, and the end of the telescopic drive chain 6 is fixed on the second telescopic arm 8 near the driving sprocket 5. Under the rotational driving force of the second drive motor 4, the driving sprocket 5 is driven to rotate, and the driving sprocket 5 carries the telescopic drive chain 6 to move around the driving sprocket 5 and the driven sprocket 7. The second telescopic arm 8 is driven to perform telescopic movement through the telescopic drive chain 6 and extend out from the first telescopic arm 3.

[0032] The fixed part of the third drive motor 9 is installed on the second telescopic arm 8, and the working bucket 10 is installed on the rotating part of the third drive motor 9. Under the rotational driving force of the third drive motor 9, the working bucket 10 can be rotated and the working angle of the working bucket 10 can be adjusted to facilitate the operation of the staff on the workbench.

[0033] In particular, in this embodiment, the driving motors of the aerial work boom can be controlled by the central control platform, and the driving motors include: a first driving motor 2, a second driving motor 4, and a third driving motor 9, which can be a hydraulic motor or an electric motor and other forms of rotational power.

[0035] When working, the aerial work vehicle controls the operation of the drive motor through the central control platform, and the operating status of the aerial work boom, such as Figure 2 shown.

[0036] Firstly, the first driving motor 2 controls the angle between the first telescopic arm 3 and the horizontal plane through the rotation driving force, so as to realize the up and down amplitude variation movement of the first telescopic arm 3 .

[0037] Then, the second drive motor 4 drives the driving sprocket 5 to rotate, and drives the telescopic driving chain 6 to move around the driving sprocket 5 and the driven sprocket 7 through the driving sprocket 5, thereby driving the second telescopic arm 8 to perform telescopic movement through the telescopic driving chain 6, so that the second telescopic arm 8 extends from the first telescopic arm 3 in the direction of the first telescopic arm 3, thereby realizing the extension of the telescopic arm.

[0038] Finally, the third driving motor 9 drives the working bucket 10 to rotate through the rotational driving force, so that the working bucket 10 is parallel to the ground.
