DETAILED DESCRIPTION

In order to make objectives, technical solutions and advantages of embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described hereunder clearly and completely with reference to accompanying drawings. Obviously, the described embodiments are only a part of embodiments of the present disclosure, rather than all of them. Any and all other embodiments obtained by persons of ordinary skill in the art based on the presently disclosed embodiments without making any creative effort shall fall into the protection scope of the present disclosure.

Fig. 1 is a schematic structural diagram of a first embodiment rotary dumping system according to the present invention, Fig. 2 is a schematic structural diagram of a helix rotary railway automatic dumping car according to the present invention, and Fig. 3 is a schematic diagram illustrating the rotation of a dumping bucket of a helix rotary railway automatic dumping car according to the present invention. As shown in Figs. 1-3 ,the rotary dumping system of the embodiment may include: a helix rotary railway automatic dumping car 1 and a track subsystem 2, where the track subsystem 2 includes: a helix track 21 and a running track 22; the helix rotary railway automatic dumping car 1 includes an underframe 11, a hinge device 12, a dumping bucket 13 and a rotary guiding device 14; the dumping bucket 13 is arranged on the underframe 11, the hinge device 12 is coupled to an outer wall of a first side of the dumping bucket 13 at a location close to the underframe 11, and to the underframe 11, respectively, the first side being a side lateral to a forward direction of the helix rotary railway automatic dumping car 1; and the rotary guiding device 14 is coupled to an outer wall of a second side of the dumping bucket 13 at location farther from the underframe 11, the second side being another side lateral to the forward direction of the helix rotary railway automatic dumping car 1. The rotary guiding device 14 moves along the helix track 21 while the helix rotary railway automatic dumping car 1 moves along the running track 22 of the track subsystem 2, driving the dumping bucket 13 to rotate about a hinge axis of the hinge device 12.

In particular, as the helix rotary railway automatic dumping car 1 moves along the running track 22, the rotary guiding device 14 will move along the helix track 21. As the

9506741_1 (GHMatters) P106876.AU

2017232096 20 Sep 2017 rotary guiding device 14 moves along the helix track 21, it leads the dumping bucket 13 to rotate about the hinge axis of the hinge device 12. During this rotation, bulk goods in the dumping bucket 13, such as ore, sand, coal, building materials, may fall out of the dumping bucket, accomplishing the unloading.

Alternatively, there may be one or more hinge devices 12.

Alternatively, the helix rotary railway automatic dumping car 1 may be driven along the running track 22 by the effort of a self-equipped power device or by the traction of other power device.

Alternatively, the helix track 21 may follow a left-hand spiral, or right-hand spiral, or a combination of left and right-hand spiral, which will not be limited herein.

It should be noted that the only condition for the helix track 21 to observe is to allow the rotary guiding device 14, when moving along the helix track 21, to drive the dumping bucket 13 into a rotation about the hinge axis of the hinge device 12 while the helix rotary railway automatic dumping car 1 is moving along the running track 22. The present invention does not limit the specific form of the helix track 21. Alternatively, a center line of the helix track 21 may be parallel with the running track 22.

The presently provided embodiment rotary dumping system includes: a helix rotary railway automatic dumping car and a track subsystem, where the track subsystem includes a helix track and a running track; the helix rotary railway automatic dumping car includes an underframe, a hinge device, a dumping bucket and a rotary guiding device; the dumping bucket is arranged on the underframe, the hinge device is coupled at one end to a lower location on an outer wall of a first side (which is a side lateral to a forward direction of the helix rotary railway automatic dumping car) of the dumping bucket, and at another end to the underframe, the rotary guiding device is coupled to an upper location on an outer wall of a second side (which is another side lateral to the forward direction of the helix rotary railway automatic dumping car) of the dumping bucket. The rotary guiding device moves along the helix track while the helix rotary railway automatic dumping car moves along the running track, driving the dumping bucket to rotate about a hinge axis of the hinge device. Thus, a rotary dumping system is implemented on the basis of a simple

9506741_1 (GHMatters) P106876.AU

2017232096 20 Sep 2017 mechanism, thereby evading the problem where complex pneumatic or hydraulic rotary dumping system leads to higher failure rate, and improving reliability for the rotary dumping system. In addition, the present embodiment allows the rotary guiding device to move along the helix track while the helix rotary railway automatic dumping car moves along the running track, which drives the dumping bucket to rotate about the hinge axis of the hinge device, thereby unloading the cargo without stopping the car, and improving the efficiency for the rotary dumping system in the unloading.

Fig. 4 is a schematic structural diagram of a second embodiment rotary dumping system according to the present invention. On the basis of the rotary dumping system shown in Fig. 1, this embodiment may further include a locomotive 3 which is coupled to the underframe 11 of the helix rotary railway automatic dumping car 1 for driving the helix rotary railway automatic dumping car 1 to move along the running track 22.

Alternatively, the locomotive 3 may be coupled to the underframe 11 through a coupler and draft gear provided on the locomotive 3 and the underframe 11.

Alternatively, there may be one or more helix rotary railway automatic dumping cars 1.

When there are more than one, a plurality of the helix rotary railway automatic dumping car 1 are grouped into a car set, and a head-car among the car set is coupled to the locomotive 3.

Alternatively, the plurality of helix rotary railway automatic dumping cars 1 forming the car set may also be coupled to each other through the coupler and draft gear.

Alternatively, the rotary dumping system of the embodiment further includes a conveying subsystem 4. As shown in Figs. 5-7, the conveying subsystem 4 includes a pit 41 and a conveyor 42, the pit 41 being disposed on the first side of the running track 22 below the helix track 21. The bulk freight in the dumping bucket 13 is dumped into the pit

41 while the dumping bucket 13 is rotating about the hinge axis of the hinge device12. The conveyor 42 is located below the pit 41 to transfer the bulk freight dumped into the pit 41 to a destination. In the present embodiment, the rotary dumping system further includes the conveying subsystem, so that the bulk freight that is carried in the helix rotary railway automatic dumping car and unloaded by the rotary dumping system may be transferred directly to the destination, improving the flexibility for the unloading site.

Alternatively, there may also be one or more pits 41 to meet the demand of the unloading. When there are a plurality of pits, each pit will correspond to at least one conveyor 42.

Alternatively, the pit 41 may be formed into a funnel-shaped, with larger sectional area 5 being closer to the ground.

Alternatively, the dumping bucket 13 may rotate about the hinge axis of the hinge device 12: firstly, by a predefined angle along a first direction; then, by the predefined angle along a second direction, where either the first direction is counter-clockwise and the second direction is clockwise, or the first direction is clockwise and the second direction is counter-clockwise. The predefined angle may be the minimum angle capable of ensuring complete unloading of the cargo in the dumping bucket. In this embodiment, the dumping bucket 13 begins from rotating along the first direction about the hinge axis by the predefined angle to complete the unloading, then proceeds to rotating along the second direction about the hinge axis by the predefined angle. Thus, on top of the automatic dumping, the dumping bucket may further be restored to its original position after the rotary dumping, thereby improving the operational continuity for the rotary dumping system.

Alternatively, the predefined angle is greater than (148 - offset) degrees, and is less than or equal to 148 degrees.

It should be noted that, when the number of helix rotary railway automatic dumping car

1 is one, Fig. 4 may show the entire unloading process for the helix rotary railway automatic dumping car. When there are more helix rotary railway automatic dumping cars 1, Fig. 4 may show an instant moment for the rotary dumping system during an unloading process. The arrow in Fig. 4 indicates the movement direction for the helix rotary railway automatic dumping car along the running track.

Fig. 8 is a front view illustrating an unloading process for a single helix rotary railway automatic dumping car based on a rotary dumping system according to the present invention shown in Figure 4, Fig. 9 is a side view illustrating an unloading process for a single helix rotary railway automatic dumping car based on a rotary dumping system according to the present invention shown in Figure 4, and Fig. 10 is a top view illustrating an unloading process for a single helix rotary railway automatic

9506741_1 (GHMatters) P106876.AU

2017232096 20 Sep 2017 dumping car based on a rotary dumping system according to the present invention shown in Figure 4. As shown in Figs. 8 to 10, a single helix rotary railway automatic dumping car will pass by points A, B, C and D in that order. The point A is where the unloading begins, and a rotary guiding device 14 of the helix rotary railway automatic dumping car 1 begins to engage a helix track 21. As the helix rotary railway automatic dumping car 1 moves forward along the running track, the rotary guiding device 14 moves along the helix track 21, and the dumping bucket passes by the point B (when it is partially unloaded) and then to the point C (when the helix rotary railway automatic dumping car 1 has rotated by the predefined angle and completed the unloading). After reaching the point C, the dumping bucket is driven on by the rotary guiding device 14 to the point D. In this case, the dumping bucket unloads during the point A to C, and resets during the point C to D. It should be noted that Fig. 9 is a side view taken facing a rear direction of the helix rotary railway automatic dumping car. The dumping bucket 13 rotates clockwise about the hinge axis to unload when the helix rotary railway automatic dumping car 1 moves from the point A to B then to C as shown in Fig. 8. The dumping bucket 13 rotates counterclockwise about the hinge axis to return its position when the helix rotary railway automatic dumping car 1 moves from the point C to D.

It should be noted that the arrows in Figs. 8 and 10 indicate the movement direction for the helix rotary railway automatic dumping car along the running track.

As shown in Fig. 4, when the locomotive 3 pulls a car set that includes a plurality of helix rotary railway automatic dumping car 1 along the helix track 21 continuously, each helix rotary railway automatic dumping car 1 passes by the points A, B, C and D as shown in Figs. 8-10 to complete its unloading process. It can be seen that there may be four helix rotary railway automatic dumping cars 1 in the helix track 21 at the same time, greatly improving the efficiency for the unloading operation.

Fig. 11 is a front view of a track subsystem according to the present invention, Fig. 12 is a side view of a track subsystem according to the present invention, and Fig 13 is a top view of a track subsystem according to the present invention. As shown in

Figs. 11-13, the track subsystem 2 includes a helix track 21 and a running track 22.

9506741_1 (GHMatters) P106876.AU

2017232096 20 Sep 2017

The helix track 21 may be formed by H section steels being installed and welded along the motion curve of the rotary guiding device 14. Alternatively, the helix track 21 is a three-section type track, and the rotation guide 14 is always located above the helix track 21. As shown in Fig. 13, the helix track 21 may particularly include a first section helix track 211, a second section helix track 212 and a third section helix track 213. Alternatively, the three-section type track may be joined by a coupling device 23. As shown in Fig. 14, the coupling device 23 may in particular be a box-like structure formed by plates being installed and welded together. In this embodiment, the helix track 21 is a three-section type track, and the rotary guiding device 14 is always above the helix track 21, so that the helix track does not need to include any groove for restricting the rotary guiding device, thereby simplifying the design of the helix track.

Alternatively, the track subsystem 2 may further include a supporting frame 24. The supporting frame 24 may include a truss 241 and a track support 242, where the truss 241 is formed by square steels being installed and welded together, with one end retained on the ground and another end coupled to the track support 242; the track support 242 is matched to, and retains, the helix track 21. Alternatively, the track support 242 may be formed by circular tubes being installed and welded together. Alternatively, the helix track 21 may be retained on the track support 242 by a suspension set 25 shown in Fig. 15. The suspension set 25 may be formed by a straight coupling plate 251, a sling 252, and an arc coupling plate 253.

This embodiment provides a rotary dumping system that requires only the locomotive to provide the traction for pulling the helix rotary railway automatic dumping car continuously through the track support along an unloading platform in order to realize a continuous automatic unloading. The system is simply structured, labor efficient in unloading, with low cost for construction and maintenance, and may be well adapted to various forms of bulk freight, such as concentrate ore, frozen ore and coal. Moreover, the rotary dumping system provides an unloading mode that does not need to stop or uncouple any car, thereby greatly enhancing efficiency for the unloading, increasing vehicle turnover rate, and reducing cost for the unloading.
