[0035] Specifically, the servo motor 6 is started, the rotating shaft of the servo motor 6 rotates, driving the turntable 7 to rotate, thereby driving the first connecting rod 8 to move, and then the first connecting rod 8 drives the transmission assembly 10 to move, and finally, the transmission assembly 10 drives the first cantilever 3 to rotate, and the first cantilever 3 rotates around the hinge position between it and the lamp post 2, until the first cantilever 3 reaches the required position, that is, the end of the first cantilever 3 away from the hinge position between it and the lamp post 2 reaches a suitable position from the ground, and the servo motor 6 is turned off. The second cantilever 4 is the same, and finally, until the staff can inspect and maintain the street lamp body 5 on the first cantilever 3 and the second cantilever 4 without the help of climbing equipment.

[0036] The base 1 is used to connect with the pre-buried foundation on the ground, and the top two side walls of the lamp post 2 are provided with notches to provide space for the rotation path of the first cantilever 3 and the second cantilever 4, and the first connecting rod 8 and the second connecting rod 9 are coplanar on a vertical plane perpendicular to the rotating shaft of the servo motor 6, ensuring the accuracy of the movement of the first connecting rod 8 and the second connecting rod 9 and increasing the service life of the transmission assembly 10. The hinge position of the first cantilever 3 and the second cantilever 4 and the lamp post 2 is preferably inside the lamp post 2, which can protect the transmission assembly 10.

[0037] It should be noted that the rotation angle of the turntable 7 is controlled by the number of rotations of the rotating shaft of the servo motor 6, and then the first connecting rod 8 and the second connecting rod 9 are controlled, and finally the first cantilever 3 and the second cantilever 4 are controlled to rotate through the transmission assembly 10. Regarding the rotation control of the rotating shaft of the servo motor 6, it can be a pre-set parameter, or it can be controlled by a controller, and the controller is preferably a B60A1E-002 constant drive servo drive controller. The above-mentioned control of the rotation angle of the rotating shaft of the servo motor 6 is a technical common sense known to those skilled in the art, and this application does not limit or improve it, so it will not be repeated here.

[0038] In some embodiments, the transmission assembly 10 includes a first tooth plate 1001 and a second tooth plate 1002, the first tooth plate 1001 is hinged to the first connecting rod 8, the second tooth plate 1002 is hinged to the second connecting rod 9, the first tooth plate 1001 and the second tooth plate 1002 slide in the first guide groove 1005, the first guide groove 1005 is arranged on the inner wall of the lamp post 2, the first cantilever 3 is provided with a first annular tooth 1003 at one end thereof near the hinge position with the lamp post 2, the second cantilever 4 is provided with a second annular tooth 1004 at one end thereof near the hinge position with the lamp post 2, the first tooth plate 1001 is meshed with the first annular tooth 1003, and the second tooth plate 1002 is meshed with the second annular tooth 1004.

[0039] Specifically, the rotating shaft of the servo motor 6 rotates, driving the rotating disk 7 to rotate. This drives the first connecting rod 8 and the second connecting rod 9 to move.

Finally, the first cantilever 3 and the second cantilever 4 are subjected to a horizontal force, and both rotate around the lamp post 2.

[0040] Among them, during most of the time when the turntable 7 rotates, the angles between the first cantilever 3 and the second cantilever 4 and the horizontal plane are not the same. Since the first connecting rod 8 and the second connecting rod 9 are hinged at the same position on the turntable 7, during the rotation of the turntable 7, only when the hinge positions of the first connecting rod and the second connecting rod and the turntable 7 are at the highest point and the lowest point in the horizontal position, the angles between the first cantilever 3 and the second cantilever 4 and the horizontal plane are the same. When it is necessary to repair the street lamp body 5 on the first cantilever 3 and the second cantilever 4 at the same time, the servo motor 6 is controlled to make the hinge position on the turntable 7 at the lowest point in the horizontal position to reach the street lamp repair state. When the repair is completed, the servo motor 6 is controlled to make the hinge position on the turntable 7 at the highest point in the horizontal position to reach the working state.

[0062] The second connecting rod 9 drives the second tooth plate 1002, the second annular gear 1004, the fourth annular gear 1009 and the fourth tooth plate 1007, thereby controlling the rotation of the second cantilever 4. The second lampshade 26 drives the second fixing block 28 to slide on the second cantilever 4 according to the rotation of the second cantilever 4, and the second fixing rod 30 pulls the second lampshade 26 to rotate around the second fixing block 28. The second sleeve 12 is pushed outward by the second transmission rod 35, and the second sleeve 12 slides on the second cantilever 4.

[0063] When the street lamp body 5 reaches a height at which a worker can stand on the ground for maintenance, the servo motor 6 is controlled to stop rotating and the street lamp body 5 is maintained. After the maintenance is completed, the rotating shaft of the servo motor 6 is controlled to rotate a preset number of circles and reverse the rotation direction again, and the steps are the same as above, so that the upper lamp post 201 rises, thereby restoring the working state.
