The working principle of the utility model is as follows:

as shown in fig. 2, when loading, the hopper door 12 is closed, and the actuating arm 14 drives the latch 16 to be inserted into the fixing seat 15. At this moment, the rail car 100 stops on the track above the loading platform, directly feeds materials into the hopper through the feeder, and the buffer net 25 is arranged in the hopper 8, so that the materials entering the hopper 8 are buffered, and the impact of the materials on the hopper and the empty rail is reduced.

As shown in fig. 2, when the rail car 100 enters a discharging point above a discharging area, the worm gear winch 7 is started, the worm gear winch 7 releases the cable 11 downwards, the hopper 8 swings downwards along a hinged point with the frame, the starting arm 14 drives the bolt 16 to move upwards relative to the hopper door 12, after a set angle is reached, the bolt 16 of the hopper door 12 is disengaged, the hopper door 12 is opened, and the material begins to leak downwards. The worm gear hoist 7 continues to work until the materials in the hopper are completely unloaded, and the rail car continues to run at a reasonable speed all the time in the unloading process. After unloading, the worm gear hoist 7 begins to recover the cable 11, the hopper door 12 is closed gradually under the action of gravity, the starting arm 14 drives the bolt 16 to move downwards relative to the hopper door 12, and the bolt 16 of the hopper door resets into the fixed seat 15 to complete the fixing operation.

Similarly, as shown in fig. 3, 4 and 5, the hopper 8 swings downwards under the action of the worm gear winch 7, the starting arm 14 drives the hinge shaft 18 to move upwards relative to the hopper door 12, the compression bar 19 moves upwards under the action of the return spring 20, the hook 21 loses the limit of the compression bar 19, and rotates upwards under the drive of the torsion spring 22 to return to a free state, at the moment, the fixed pin shaft 23 loses constraint, the hopper door 12 gradually swings downwards along with the hopper 8 to open, and the material begins to leak downwards. The worm gear winch 7 continues to work until the unloading of all materials is finished. Then, the worm gear hoist 7 starts to recover the cable 11, the hopper 8 swings upwards, the hopper door 12 gradually approaches the hopper 8 under the action of gravity, at the moment, the starting arm 14 supports the hinge shaft 18 to move downwards and compress the pressing rod 19, and the pressing rod 19 moves downwards against the hook 21 and is gradually hung on the fixed pin shaft 23, so that the fixing operation is completed.

After the hopper 8 is reset, the railcar 100 returns to the loading platform along the ascending track.

As shown in fig. 6, the actuating arm 14 also protects the hopper 8 from damage due to loss of restraint in the event of an accidental cable breakage.

When the air rail transportation device runs normally and turns, the front and rear driving devices 4 rotate under the guidance of the slewing bearing 2 and the air rail 5, the rail car 100 finishes turning, and the driving wheel 3, the upper guide wheel 26 and the lower guide wheel 27 play a role in supporting and stabilizing the rail car 100.
