[0018] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below in conjunction with the accompanying drawings.

[0019] like Figure 1 As shown, a tire explosion-proof device for engineering machinery equipment includes a base plate 1, on which a rectangular channel steel guide rail 2 and an explosion-proof cage 4 are welded, the channel steel guide rail 2 is located inside the explosion-proof cage 4 and extends out of the explosion-proof cage 4, the channel steel guide rail 2 is configured with a groove opening inward, and the groove is slidably matched with a tire moving vehicle 8; the tire moving vehicle 8 is a rectangular frame structure for fixing tires, and the tire moving vehicle 8 is connected to a driving mechanism; the explosion-proof cage 4 is provided with an explosion-proof door 10.

[0020] The driving mechanism includes a driving motor 5, which is fixedly connected to the tire mobile vehicle 8 through a linkage shaft, and the power output shaft of the driving motor 5 is fixedly connected to the transmission gear 7, which is meshed with the rack 6, and the rack 6 is fixedly installed on the top of the channel steel guide rail 2; a limit sensor 9 is provided at one end of the rack 6 located inside the explosion-proof cage 4, and the other end of the rack 6 is connected to a limit plate 13, which prevents the gear from disengaging from the rack and is used to limit the outward movement of the tire mobile vehicle 8; a movable door opener 3 is provided at the top inner side of the explosion-proof cage 4; the signal output ends of the limit sensor 9 are connected to the signal input ends of the external controller, the signal input end of the movable door opener 3 is connected to the signal output end of the external controller, and the signal output end of the movable door opener 3 is connected to the signal input end of the explosion-proof door 10.

[0021] A camera 11 is also provided at the diagonal of the top inner side of the explosion-proof cage 4. The signal output end of the camera 11 is connected to the signal input end of the external controller for real-time monitoring of the inflation process of the tire inside the explosion-proof cage 4 to prevent dangerous accidents.

[0022] like Figure 2 As shown, the explosion-proof cage 4 is welded with a breathable plate 12 around it, and the breathable plate 12 has a plurality of small circular holes processed on the surface. During the tire inflation process, if a tire blows out, a large airflow is generated, and the airflow can release the air pressure to the surroundings through the small circular holes of the breathable plate 12, thereby avoiding harm to external personnel.

[0023] In this embodiment, the model of the movable door opener 3 is HCS-PYMJ3000; the model of the camera 11 is XYIR384.

[0024] The working principle of the utility model is as follows:

The movable door opener 3 controls the explosion-proof door 10 to open, and the drive motor 5 is started. The drive motor 5 drives the tire moving vehicle 8 to move into the explosion-proof cage 4 through the meshing transmission of the gear and the rack. When it moves to the limit sensor 9, the limit sensor 9 detects a signal and transmits the signal to the external controller. After processing, the external controller transmits the signal to the movable door opener 3, and the movable door opener 3 controls the explosion-proof door 10 to close, and at the same time turns off the drive motor 5 to start inflating the tire; when the inflation is completed, the external controller sends a signal to the movable door opener 3 to control the explosion-proof door 10 to open, and starts the drive motor 5 again, driving the tire moving vehicle 8 to move out of the explosion-proof cage 4, and stops moving when it moves to the limit plate 13; when a tire blowout occurs during the tire inflation process, the air permeable plate 12 welded around the explosion-proof cage 4 can guide a large amount of airflow to be released around, thereby avoiding harm to external personnel.
