[0024] As Figure 1 shown, a self-unloading bulk material aerial rail transport rail car includes a vehicle frame 1. Rotary supports 2 are respectively arranged at both ends of the vehicle frame 1. The rotary supports 2 are respectively connected to wheel frames 3. The wheel frames 3 are U-shaped. A driving device 4 is arranged on the wheel frames 3. The driving device 4 is connected to driving wheels 24. The driving wheels 24 are rotatably arranged on the aerial rail 5. In this way, driven by the driving device 4, the driving wheels 24 can roll on the aerial rail 5.

[0025] A hopper 8 is arranged below the vehicle frame 1. One end of the hopper 8 is hinged to one end of the vehicle frame 1 through a lifting lug 9, and the above-mentioned one end of the vehicle frame 1 is connected to the rotary support 2. A pulley 10 is arranged on the upper end surface of the other end of the hopper 8. A cable 11 is wound around the pulley 10. One end of the cable 11 is fixedly connected to the vehicle frame 1, and the other end of the cable 11 is connected to a worm and gear winch 7. The worm and gear winch 7 is arranged on a suspension arm 6. The suspension arm 6 is arranged at the other end of the vehicle frame 1.

[0026] In addition, a hopper door 12 is hinged to one side of the hopper 8. The hopper door 12 is located outside the pulley 10. A door locking device 13 is arranged on the hopper door 12. A starting arm 14 is arranged between the door locking device 13 and the vehicle frame 1 for connection. A fixed seat 15 is arranged on the lower end surface of the hopper 8. The door locking device 13 is cooperatively connected to the fixed seat 15.

[0027] As Figure 2As shown in the figure, a latch device 13 of a structure is provided with a bolt 16. The bolt 16 is set in a T-shaped structure. The upper cross beam of the bolt 16 is hingedly connected to the starting arm 14. Both ends of the bolt 16 are respectively suspended in the long slot holes 17 provided on the hopper door 12.

[0028] As Figure 3 shown in the figure, for a latch device 13 of another structure, the hopper door 12 and the starting arm 14 are hingedly connected through a hinge shaft 18. The hinge shaft is arranged in the long slot hole 17 provided on the hopper door 12. A pressure bar 19 is arranged below the hinge shaft 18. The pressure bar 19 is arranged on the hopper door 12. A return spring 20 is arranged between the pressure bar 19 and the hopper door 12. The pressure bar 19 can stretch along the hopper door 12. A hook 21 is arranged at the bottom of the hopper door 12. The hook 21 is hingedly connected to the hopper door 12. A torsion spring 22 is connected between the hook 21 and the hopper door 12. One end of the torsion spring 22 is fixedly connected to the hopper door 12, and the other end of the torsion spring 22 is fixedly connected to the hook 21. The pressure bar 19 is arranged above the hook 21. A fixed pin shaft 23 is arranged below the hook 21. The fixed pin shaft 23 is fixedly connected to the bottom of the hopper 8.

[0029] Furthermore, the wheel frame 3 is buckled on the empty rail track 5. The driving wheel 24 of the rail vehicle 100 is arranged on the empty rail track 5. The driving wheel 24 is in contact with the empty rail track 5. The driving wheel 24 is provided with an upper guide wheel 26 and a lower guide wheel 27. The upper guide wheel and the lower guide wheel are respectively supported on the web and the lower wing plate of the empty rail track 5.

[0030] Furthermore, a buffer net 25 is also arranged in the hopper 8.

[0031] The working principle of the present invention is as follows:

[0032] As Figure 2 shown in the figure, during loading, the hopper door 12 is in a closed state. The starting arm 14 drives the bolt 16 to insert into the fixed seat 15. At this time, the rail vehicle 100 stops on the track above the loading platform. The material is directly fed into the hopper through the feeder. A buffer net 25 is arranged in the hopper 8 to buffer the material entering the hopper 8 and reduce the impact of the material on the hopper and the empty rail.

[0033] As Figure 2As shown in the figure, when the rail vehicle 100 enters the unloading point above the unloading area, the worm gear winch 7 is started. The worm gear winch 7 releases the cable 11 downward. The hopper 8 swings downward along the hinge point with the vehicle frame. The starting arm 14 drives the bolt 16 to move upward relative to the hopper door 12. After reaching the set angle, the bolt 16 of the hopper door 12 disengages, the hopper door 12 opens, and the material begins to discharge. The worm gear winch 7 continues to work until all the material in the hopper is unloaded. The rail vehicle continues to travel at a reasonable speed throughout the unloading process. After unloading, the worm gear winch 7 starts to retract the cable 11. The hopper door 12 gradually closes under the action of gravity. The starting arm 14 drives the bolt 16 to move downward relative to the hopper door 12. The bolt 16 of the hopper door is reset into the fixed seat 15 to complete the fixing operation.

[0034] Similarly, as Figure 3 , 4 , as shown in Figure 5, the hopper 8 swings downward under the action of the worm gear winch 7. The starting arm 14 drives the hinge shaft 18 to move upward relative to the hopper door 12. The pressure rod 19 moves upward under the action of the return spring 20. The hook 21 loses the limit of the pressure rod 19 and rotates upward under the drive of the torsion spring 22 to return to the free state. At this time, the fixed pin shaft 23 loses restraint. The hopper door 12 opens as the hopper 8 gradually swings downward, and the material begins to discharge. The worm gear winch 7 continues to work until all the material is unloaded. Then, the worm gear winch 7 starts to retract the cable 11. The hopper 8 swings upward. The hopper door 12 gradually approaches the hopper 8 under the action of gravity. At this time, the starting arm 14 supports the hinge shaft 18 to move downward and compresses the pressure rod 19. The pressure rod 19 pushes the hook 21 to move downward and gradually hooks onto the fixed pin shaft 23 to complete the fixing operation.

[0035] After the hopper 8 is reset, the rail vehicle 100 returns to the loading platform along the upward track.

[0036] As Figure 6 shown, when the cable breaks accidentally, the starting arm 14 can also play a role in protecting the hopper 8 to prevent the hopper from being damaged due to loss of restraint.

[0037] When the aerial rail transportation device operates normally and encounters a turn, the front and rear drive devices 4 rotate under the guidance of the slewing bearing 2 and the aerial rail track 5. The rail vehicle 100 completes the turning. The drive wheels 3, the upper guide wheels 26, and the lower guide wheels 27 play a role in supporting and stabilizing the rail vehicle 100. Slewing bearings 2 are provided below both the front and rear drive devices, making the turning of the rail vehicle smoother. At the same time, it can run smoothly both forward and backward.

[0038] The above are only the preferred embodiments of the present invention. It should be noted that for those skilled in the art, without departing from the overall concept of the present invention, several changes and improvements can still be made, and these should also be regarded as the protection scope of the present invention.
