[0002] Aircraft tires refer to pneumatic tires used on aircraft. They are important components of aircraft with high safety and reliability requirements. They ensure the safe takeoff, landing, taxiing and docking of the aircraft. Aircraft tires move the aircraft through friction with the ground, bear the weight of the aircraft during takeoff, and absorb and disperse the impact force during landing, protecting the aircraft structure from damage.

[0003] Existing tire inspection devices, such as a tire appearance inspection machine disclosed in Chinese utility model patent application number CN2023216199984, have a main structure including an inspection platform and a conveyor belt. A fixed frame is fixed to the upper end of the inspection platform, and a detection machine body is fixed to the top inner side of the fixed frame. When in use, the tire is limited by a sleeve on the surface of the conveyor belt and slowly conveyed to the inner side of the inspection platform.
