There are two tires inside the vehicle frame 1. The anti - release brake 8 is in contact with the tire. Only after contacting the tire can the anti - release brake 8 fix the tire. The top of the water tank 1002 is threadedly connected with a ventilation valve 1009. The function of the ventilation valve 1009 is to balance the internal and external air pressures of the water tank 1002. An anti - slip sleeve is sleeved outside the ventilation valve 1009. At the water injection port in the middle of the top of the water tank 1002, a rotating cover 1010 is threadedly connected. The function of the rotating cover 1010 is to facilitate water injection into the water tank 1002. Anti - slip patterns are fixedly connected to the outside of the rotating cover 1010.

[0037] Working principle: when the aircraft tire enters the interior of the frame 1, the hydraulic cylinder 7 is started, and the output end of the hydraulic cylinder 7 is extended, so that the slider 5 can be driven to move in the direction away from the tire, thereby driving the anti-slip brake 8 to rotate downward, and at the same time, the support rod 9 rotates in the direction of the driving frame 6, so that the top of the anti-slip brake 8 can be stuck on the outside of the tire, thereby preventing the tire from sliding, and then playing a role in preventing the tire from slipping. When the tire is released from the interior of the frame 1, the hydraulic cylinder 7 is first started, and the output end of the hydraulic cylinder 7 is extended, so that the slider 5 can be driven to move in the direction of the tire. Under the support of the support rod 9, the anti-slip brake 8 rotates upward, so that the tire can be released. When the tire is stuck on the anti-slip brake 8, the water pump 1001 is started, and the input end of the water pump 1001 draws water from the water tank 1002, and through the water inlet pipe 1007, the water is pumped into the interior of the connecting pipe 1005, and is transmitted to the interior of the water pipe 1003 through the hose 1004, so that the water can be sprayed out through the nozzle 1006, which plays a role in cooling the tire.
