[0016] Working principle: When the aluminum material needs to be purged with inert gas, the gas purging pipe 31 is dragged to the purging position of the aluminum material pipe mouth, and connected to the aluminum material pipe mouth through the quick-plug connector 33, and the ball valve 34 and the gas source connecting valve 73 connected to the connecting hose 26 are opened. After the gas source connecting valve 73 is opened, the inert gas in the gas cylinder 6 flows into the gas source connecting pipe 7 through the gas cylinder connecting pipe 75, and the inert gas passes through the connecting branch pipe 72, the connecting main pipe 71, the gas source connecting valve 73, the connecting hose 26 and the gas pressure reducing valve 23 in sequence, and the inert gas is reduced in pressure through the gas pressure reducing valve 23; the switching switch 42 is rotated to the automatic control gear, and the on-off time of the corresponding solenoid valve 22 is controlled by setting the time controller 44. After the solenoid valve 22 is opened, the inert gas is purged from the gas purging pipe 31 into the aluminum material pipe; when the solenoid valve 22 reaches the time set by the time controller 44, it is closed to complete the purging of the aluminum material; When an emergency situation requires manual purging, the switch 42 is rotated to the manual control position, the solenoid valve 22 is opened, and the aluminum material is manually purged after the ball valve 34 is opened. After the manual purging is completed, the ball valve 34 is closed, and the switch 42 is rotated to the stop position, and the solenoid valve 22 is closed; after the purging is completed, the gas purging pipe 31 is automatically reeled in by the automatic pipe winding device 32; the pressure gauge 1 27 and the pressure gauge 2 74 display the air pressure before the air source is decompressed, and the alarm 45 will sound and light alarm when the pressure of the air source is too high or too low; When the inert gas in the gas cylinder 6 is about to be exhausted, the gas pressure of the gas source connecting pipe 7 is too low to be directly used for purging the aluminum pipe. The gas source connecting valve 73 connected to the connecting hose 26 is closed, the gas source connecting valve 73 connected to the extraction pipe 94 is opened, and the two-way pump 93 is opened to extract the inert gas remaining in the gas source connecting pipe 7 and the gas cylinder 6 into the gas temporary storage box 91. When the inert gas remaining in the gas source connecting pipe 7 and the gas cylinder 6 is exhausted, the two-way pump 93 is closed, and the gas source connecting valve 73 connected to the extraction pipe 94 is closed. The third pressure gauge 92 displays the pressure of the inert gas in the temporary gas storage box 91. The inert gas in the temporary gas storage box 91 can be used to purge the gas purge pipe 31 and the gas source connecting pipe 7 to improve the safety of gas purge. The inert gas remaining in the gas cylinder 6 of the next batch can also be collected multiple times by the two-way pump 93.

After the sliding support plate 83 is placed downward, it is tilted and swung downward around the limiting shaft 82 through the bending head 831, and the flip pad 84 is swung outward in the vertical direction. Then, the lap plate 85 is flipped outward in the vertical direction, so that the lap plate 85 is overlapped on the gas cylinder. The bottom plate of the vehicle frame 5 is formed by a ground support inclined surface 833 provided on the bottom surface of the outer end of the sliding support plate 83, and the ground support end plate 841 provided on the rotating end of the flip pad 84 is in contact with the ground.
