[0002] When transporting containerized coal by train, the coal is unloaded by a dumper, which is an important production equipment for unloading coal in railway and rail transportation. Usually, the dumper clamps the container with the top pressure beam and the support plates on both sides. As the dumper turns 180 degrees, the container turns over with the top facing down, and the coal is poured into the coal pit below the dumper. However, in actual use, due to the structural problems of the container, it is often the case that there is residual coal after unloading and turning the container back to the right position. This is because the structure of the container is Figure 1 , Figure 2 As shown, the container 9 includes a bottom plate, side plates 9.1 on both sides and end plates 9.2 at both ends. The top of the side plate 9.1 protrudes inward, and when the top is facing downward, a dead corner 10 is formed; similarly, the top of the end plate 9.2 has a water guide groove 11 structure, and the edge is bent into the box. When the top is facing downward, a dead corner 10 is also formed. These dead corners 10 are prone to coal accumulation.

[0003] Therefore, it is necessary to clean up the residual coal caused by coal accumulation in dead corners in time after unloading the coal. Utility model content:

[0024] like Figure 3-Figure 7 As shown, a purging device for unloading a railway container comprises a main pipeline 1, a connecting plate 2, an arc-shaped nozzle 3, a hydraulic cylinder 4, a connecting structure 5, and an air supply system 6. The main pipeline 1 is placed on one side of a car pressing beam 12 of a car tipping machine. A plurality of connecting plates 2 are rotatably sleeved on the main pipeline 1. The connecting plates 2 are fixed to the corresponding car pressing beams 12. A plurality of arc-shaped nozzles 3 are connected to the main pipeline 1 at intervals. A nozzle 7 is provided at the far end of the arc-shaped nozzle 3. The main pipeline 1 can rotate on the connecting plate 2 and drive the plurality of arc-shaped nozzles 3 to flip. The far end of the arc-shaped nozzle 3 reaches one side of the top of the side plate 9.1 of the container 9. The nozzle 7 of the arc-shaped nozzle 3 faces the dead corner 10 at the top of the side plate 9.1. The arc-shaped nozzle 3 adjacent to the end plate 9.2 of the container 9 has a nozzle 7 covering the dead corner 10 at the top of the end plate 9.2.

[0025] The hydraulic cylinder 4 is fixed to the side end of the car pressing beam 12, and the telescopic end of the hydraulic cylinder 4 is movably connected to the main pipeline 1 through the connecting structure 5. The telescopic end of the hydraulic cylinder 4 controls the reciprocating rotation of the main pipeline 1. The telescopic movement of the telescopic end of the hydraulic cylinder 4 can drive the rotation of the main pipeline 1.

[0026] The connecting structure 5 includes an arc groove 5.1 and a push rod 5.2. The arc groove 5.1 is fixed on the main pipeline 1. The push rod 5.2 is inserted into the arc groove 5.1, and one end of the push rod 5.2 is fixed to the telescopic end of the hydraulic cylinder 4. The hydraulic cylinder 4 drives the main pipeline 1 to rotate. The telescopic end of the hydraulic cylinder 4 is extended and retracted to drive the push rod 5.2 to move in the arc groove 5.1. At the same time, the push rod 5.2 pushes or pulls the arc groove 5.1, so that the main pipeline 1 completes the rotation or reset rotation of the flip arc nozzle 3.

[0027] The main pipeline 1 is connected to the air outlet of the air supply system 6 through the short-circuit hose 8. When the main pipeline 1 rotates, the short-circuit hose 8 can be adaptively twisted. The air supply system 6 supplies high-pressure gas to the main pipeline 1 through the short-circuit hose 8. The gas is ejected from the nozzle 7 of the arc nozzle 3 to purge the dead corner 10, blow out and clean the accumulated coal in the dead corner 10, so that the accumulated coal can enter the coal receiving pit, and no coal will remain in the overturned and reset container 9.

[0028] The air supply system 6 comprises an air compressor 6.1, a bracket 6.2, a pair of guide wheels 6.3, a counterweight block 6.4, a long connecting hose 6.5, and a straight pipe 6.6. The outlet of the air compressor 6.1 is connected to one end of the long connecting hose 6.5. The other end of the long connecting hose 6.5 passes through between the pair of guide wheels 6.3 and is connected to one end of the straight pipe 6.6. The other end of the straight pipe 6.6 is the air outlet of the air supply system 6. When the air supply system 6 provides gas, the air compressor 6.1 blows out high-pressure gas, which passes through the long connecting hose 6.5 and the straight pipe 6.6 in sequence and enters the short connecting hose 8.

[0029] The counterweight 6.4 is fixed on the long connecting hose 6.5 between the air compressor 6.1 and the guide wheel 6.3; a pair of guide wheels 6.3 are rotatably connected to the top of the bracket 6.2; the straight pipe 6.6 is fixed to the car pressing beam 12. When the tipping machine turns over and unloads coal with the container 9, the straight pipe 6.6 is turned over to the bottom, and the long connecting hose 6.5 can move with it. At the same time, the long connecting hose 6.5 is pulled between the pair of rolling guide wheels 6.3 to keep it stable, and the counterweight 6.4 is pulled and lifted. When the tipping machine turns over and resets with the container 9, the straight pipe 6.6 returns to the top, the counterweight 6.4 drops due to its own weight, and the long connecting hose 6.5 is also pulled down and moved, and reset. The whole process enables the long connecting hose 6.5 to adapt to the pulling movement of the tipping machine.

[0030] Working principle:

[0031] When not purging, Figure 3 , Figure 4 , Figure 5 As shown, the hydraulic cylinder 4 drives the main pipeline 1 to rotate, and the main pipeline 1 drives multiple arc-shaped nozzles 3 to lift up, which does not hinder the container 9 from entering the tipping machine. The container 9 is turned over by the tipping machine to unload coal, and the arc-shaped nozzles 3 can also reduce the obstruction to the coal.

[0032] When purging, Figure 6, Figure 7 , the container 9 is turned over 205°, and the coal in the container 9 is dumped. This angle makes the dead corner 10 on one side of the top of the container 9 raised when the top of the container 9 is facing downward, and the dead corner 10 on the other side is located at a low position, so that the accumulated coal in the high dead corner 10 falls out by itself, or slides to the low dead corner 10. The device of the present application is installed near the low dead corner 10, and the hydraulic cylinder 4 drives the main pipeline 1 to rotate, and the main pipeline 1 drives the multiple arc nozzles 3 to turn over, and the distal end of the arc nozzle 3 is to the top side of the side plate 9.1 of the container 9, and the arc nozzle 3 is rotated. The nozzle 7 of the nozzle 3 faces the dead corner 10 at the top of the side plate 9.1, and the coverage area of ​​the nozzle 7 of the arc-shaped nozzle 3 adjacent to the end plate 9.2 of the container 9 includes the dead corner 10 at the top of the end plate 9.2; the air compressor 6.1 blows out the high-pressure gas, which passes through the long hose 6.5 and the straight pipe 6.6 in sequence and enters the short hose 8 and the main pipeline 1, and the gas is ejected from the nozzle 7 of the arc-shaped nozzle 3 to purge the dead corner 10, blow out and clean the accumulated coal in the dead corner 10, so that the accumulated coal can enter the coal receiving pit, and no coal will remain in the container 9 that is turned over and reset.

[0033] The arc-shaped nozzle 3 of the present application does not hinder the container 9 from entering the turning machine when it is not rotating. It can also stay away from the top of the container 9 when the turning machine turns the container 9 to unload coal, thereby reducing obstruction. After unloading, it can be turned over again. The nozzle 7 of the arc-shaped nozzle 3 can be close to the dead corner 10 at the top of the container 9, and spray high-pressure gas at a close distance to blow away the accumulated coal in the dead corner 10, thereby reducing or even completely clearing the residual coal in the container 9 caused by the coal accumulation in the dead corner 10.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
