[0023] By adopting the above technical solution: when adjusting the height of the second lamp pole 3, the winding mechanism 11 pulls the wire rope 13. At this time, the wire rope 13 is immediately wound into the winding mechanism 11. Moreover, during the winding process of the wire rope 13, the second lamp pole 3 can be pulled up by the traction of the third traction wheel 32, the second traction wheel 10 and the first traction wheel 9, thereby adjusting the height of the lighting lamp 5.

[0024] In this embodiment, an articulated seat 6 is fixedly installed on the side of the second lamp pole 3 and the lower end of the lamp arm 4, and a pneumatic telescopic rod 7 is connected between the articulated seat 6; by setting the pneumatic telescopic rod 7 and the articulated seat 6, the pneumatic telescopic rod 7 is extended, and the angle is adjusted in conjunction with the articulated seat 6, so as to adjust the angle of the lamp arm 4 and then adjust the illumination angle of the lighting lamp 5.

[0025] In this embodiment, a winding roller 111 is rotatably provided inside the winding mechanism 11, and the winding roller 111 is fixedly connected to the other end of the wire rope 13. A motor 12 is fixedly installed on the upper end of the winding mechanism 11. Two bevel gears 112 are meshed inside the winding mechanism 11, and the bevel gears 112 are respectively connected to the winding roller 111 and the output end of the motor 12; by providing the bevel gears 112, the winding roller 111 and the motor 12, the bevel gear 112 is driven by the output end of the motor 12 to rotate, and cooperates with another meshing bevel gear 112 to drive the winding roller 111 to rotate, thereby winding the wire rope 13.

[0026] In this embodiment, slide rails 15 are provided on both sides of the first lamp pole 2, a guide rod 14 is fixedly connected between the first lamp pole 2 and the base 1, a movable seat 31 is fixedly connected to the lower end of the second lamp pole 3, and the movable seat 31 is penetrated by the guide rod 14 to maintain a sliding setting; by setting the movable seat 31 and the guide rod 14, during the rising or falling process of the second lamp pole 3, the movable seat 31 moves along the guide rod 14, thereby ensuring the stability of the second lamp pole 3 when moving, and at the same time, playing a guiding role.

[0027] In this embodiment, a compression spring 141 is provided on the outer side of the guide rod 14; by providing the compression spring 141, the compression spring 141 is squeezed during the rising process of the moving seat 31. At the same time, the compression spring 141 gives a downward thrust to the moving seat 31, thereby increasing the stability of the second lamp pole 3 after it is raised.

[0028] The working principle and use process of the present invention are as follows: when adjusting the height of the second lamp pole 3, the motor 12 at the upper end of the winding mechanism 11 drives the winding roller 111 to rotate through the bevel gear 112, thereby pulling the wire rope 13. At this time, the wire rope 13 is wound into the winding mechanism 11, and during the winding process of the wire rope 13, the second lamp pole 3 can be pulled up by the traction of the third traction wheel 32, the second traction wheel 10 and the first traction wheel 9, thereby adjusting the height of the lighting lamp 5. At the same time, during the rising process of the second lamp pole 3, the lower end of the second lamp pole 3 is pulled up. The movable seat 31 then rises along the guide rod 14. At the same time, the compression spring 141 contracts, giving a downward thrust to the movable seat 31, thereby increasing the stability of the second lamp pole 3 after it is raised. When it descends, the motor 12 is reversed to move the wire rope 13 out of the winding mechanism 11, and the second lamp pole 3 can slowly descend, making it convenient for the staff to inspect and repair the lighting lamp 5. When the illumination angle of the lighting lamp 5 needs to be adjusted, the pneumatic telescopic rod 7 is extended, and the angle is adjusted in conjunction with the articulated seat 6 to adjust the angle of the lamp arm 4, thereby adjusting the illumination angle of the lighting lamp 5.
