[0021] Figure 5 is Figure 4 an enlarged view of area A in Detailed Description of the Embodiments

[0022] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0023] The curved rail device 100 of the unloading station according to an embodiment of the present utility model will be described below with reference to the accompanying drawings. As Figure 1 and Figure 2 shown, the curved rail device 100 of the unloading station according to an embodiment of the present utility model includes a plurality of curved rail section assemblies 1 and a plurality of support section 2. Each curved rail section assembly 1 includes a curved rail section 11, a mounting frame 12, and a plurality of cushion plates 13.

[0024] The mounting frame 12 and the curved rail section 11 are relatively and spaced apart in the vertical direction, and the curved rail section 11 is located above the mounting frame 12. The plurality of cushion plates 13 are spaced apart along the extending direction of the curved rail section 11. The upper end portion 131 of each cushion plate 13 is connected to the curved rail section 11, and the lower end portion 132 of each cushion plate 13 is connected to the mounting frame 12.

[0025] The plurality of support sections 2 and the plurality of curved rail sections 11 are relatively and spaced apart one by one in the vertical direction, and the curved rail section 11 is located above the support section 2. In other words, the number of support sections 2 is equal to the number of curved rail sections 11. Each curved rail section 11 is above one support section 2, and each support section 2 is below one curved rail section 11. The plurality of mounting frames 12 are respectively provided on the plurality of support sections 2, that is, the number of mounting frames 12 is equal to the number of support sections 2. Each mounting frame 12 is provided on one support section 2, and one support section 2 is provided with one mounting frame 12. That is to say, the plurality of curved rail section assemblies 1 are respectively provided on the plurality of support sections 2.

[0026] By providing the mounting frame 12 and connecting the curved rail section 11 to the mounting frame 12 through the cushion plate 13, when the curved rail device 100 is installed in the ore unloading chute of the unloading station, it only needs to connect the mounting frame 12 to the support section 2. Thereby, the welding time and welding difficulty can be effectively reduced.

[0027] Therefore, the curved rail device 100 of the unloading station according to an embodiment of the present utility model has the advantages of short welding time and low welding difficulty.

[0028] As Figure 1 and Figure 2 shown, the curved rail device 100 of the unloading station according to an embodiment of the present utility model includes a plurality of curved rail section assemblies 1 and a plurality of support sections 2. Each curved rail section assembly 1 includes a curved rail section 11, a mounting frame 12, and a plurality of cushion plates 13. For example, the number of curved rail section assemblies 1 can be four, and the number of support sections 2 can also be four.

[0029] The extending direction of the mounting bracket 12 is the same as that of the curved rail section 11, that is, the mounting bracket 12 and the curved rail section 11 of the same curved rail section assembly 1 extend in substantially the same direction. The curved rail section 11 is located above the mounting bracket 12, and a plurality of cushion plates 13 are provided between the curved rail section 11 and the mounting bracket 12. The upper end portion 131 of each cushion plate 13 is welded to the curved rail section 11, and the lower end portion 132 of each cushion plate 13 is welded to the mounting bracket 12.

[0030] The cushion plates 13 can be welded to the curved rail section 11 and the mounting bracket 12 in the factory, that is, the curved rail section assembly 1 can be assembled in the factory to reduce the welding time and welding difficulty in the ore unloading chute at the unloading station.

[0031] As Figure 2 shown, the mounting bracket 12 includes a plurality of sub-mounting brackets 121, and the plurality of sub-mounting brackets 121 are arranged at intervals along the extending direction of the curved rail section 11. Each sub-mounting bracket 121 is connected to the curved rail section 11 through a plurality of cushion plates 13. This can make the structure of the curved rail device 100 more reasonable and can reduce the manufacturing difficulty of the mounting bracket 12.

[0032] Optionally, a plurality of mounting brackets 12 are provided on the upper surfaces 21 of a plurality of support sections 2 one by one. For example, a plurality of mounting brackets 12 are welded to the upper surfaces 21 of a plurality of support sections 2 one by one.

[0033] As Figure 2 shown, the upper surface 21 of each support section 2 is a plane, and each mounting bracket 12 is in the shape of a flat plate. This can connect the mounting bracket 12 and the support section 2 more firmly and conveniently.

[0034] The unloading station of the present utility model includes a station body and a curved rail device 100. The station body has an ore unloading chute, and the curved rail device 100 is arranged in the ore unloading chute.

[0035] The unloading station according to the embodiment of the present utility model has advantages such as short welding time and low welding difficulty of the curved rail device 100.

[0036] The unloading station according to the embodiment of the present utility model further includes a carrying roller 4. As Figures 3 - 5 shown, the carrying roller 4 includes a shaft 41, a bearing 42, a carrying wheel 43, a first seal 44 and a particulate seal 45.

[0037] The bearing 42 is sleeved on the shaft 41, and the carrying wheel 43 is sleeved on the bearing 42. When the ore car is unloaded at the unloading station, the ore car contacts the carrying wheel 43 so that the carrying wheel 43 rotates, while the shaft 41 does not rotate. The first seal 44 is arranged between the shaft 41 and the carrying wheel 43. The particulate seal 45 is arranged between the shaft 41 and the carrying wheel 43, and the first seal 44 is axially located between the bearing 42 and the particulate seal 45 on the shaft 41.

[0038] According to the embodiment of the present utility model, the idler 4 of the unloading station is provided with a particle seal 45, so that the particle seal 45 can intercept impurities such as particles and dust, in order to avoid impurities adhering to the first seal 44 and further wearing the first seal 44. Thereby, not only can the service life of the first seal 44 be improved, and then the service life of the idler 4 be improved, but also the lubricating oil in the idler 4 can be further prevented from being oxidized and the bearing 42 from being worn, so as to extend the running time of the idler 4 and reduce the maintenance times and maintenance costs of the idler 4.

[0039] Therefore, the idler 4 of the unloading station according to the embodiment of the present utility model has the advantages of long service life, few maintenance times, low maintenance cost, long running time, etc.

[0040] Optionally, the first seal 44 can be a skeleton oil seal, and the particle seal 45 can be one of a polytetrafluoroethylene dust-proof ring and a polyurethane dust-proof ring.

[0041] The shaft 41 can be installed on the bracket 6. As Figure 3 and Figure 4 shown, the bracket 6 includes a bottom plate 471, a first mounting plate 472 and a second mounting plate 473. The bottom plate 471 is arranged on the body of the unloading station, and the first mounting plate 472 and the second mounting plate 473 are arranged on the bottom plate 471 at intervals along the axial direction of the shaft 41, and the shaft 41 is arranged on the first mounting plate 472 and the second mounting plate 473. The axial direction of the shaft 41 is as shown by the arrow B in Figure 4 in.

[0042] The shaft 41 includes a shaft body 411 and a spacer 412. The spacer 412 is sleeved on the shaft body 411, and the bearing 42 is sleeved on the shaft body 411. By providing the spacer 412, the service life of the shaft 41 can be extended. Optionally, the shaft body 411 is provided with a shaft shoulder, the spacer 412 abuts against the shaft shoulder, and the bearing 42 abuts against the spacer 412.

[0043] As Figure 5 shown, the idler wheel 43 includes a wheel body 431 and a bracket 432. The wheel body 431 is sleeved on the bearing 42, and the bracket 432 is connected to the wheel body 431 so that the wheel body 431 and the bracket 432 rotate together. Among them, there is a chamber capable of accommodating lubricating oil between the shaft 41, the bearing 42 and the idler wheel 43, and the first seal 44 is used to seal this chamber to prevent the lubricating oil from being oxidized. If the particle seal 45 is not provided, the first seal 44 will be worn by impurities, resulting in the first seal 44 being unable to seal this chamber, thereby causing the lubricating oil to be oxidized.

[0044] Each of the first seal 44 and the particle seal 45 is provided between the bracket 432 and the spacer ring 412. Each of the first seal 44 and the particle seal 45 is connected to the bracket 432 so as to rotate under the drive of the bracket 432. Thus, the structure of the idler 4 can be made more reasonable.

[0045] For example, the outer end of each of the first seal 44 and the particle seal 45 is connected to the bracket 432, and the inner end of each of the first seal 44 and the particle seal 45 abuts against the spacer ring 412.

[0046] As Figure 5 shown, the particle seal 45 includes a straight section 451 and a bent section 452. The outer end of the straight section 451 is connected to the bracket 432 of the idler 43. The outer end of the bent section 452 is connected to the inner end of the straight section 451, and the inner end of the bent section 452 abuts against the spacer ring 412 of the shaft 41.

[0047] By providing the bent section 452, the particle seal 45 can contact the spacer ring 412 more tightly, so that the particle seal 45 can intercept impurities such as particles and dust more effectively, so as to further prevent the impurities from wearing the first seal 44. Thus, not only can the service life of the first seal 44, the bearing 42 and the idler 4 be further improved, but also the maintenance times and maintenance costs of the idler 4 can be further reduced, and the running time of the idler 4 can be further extended. The wear of the first seal 44 will cause the lubricating oil in the idler 4 to be oxidized. When new lubricating oil is manually injected, impurities such as particles and dust will enter the bearing 42 along with the lubricating oil, greatly affecting the life of the bearing 42.

[0048] As Figure 5 shown, the bracket 432 includes a frame body 4321 and a first spacer ring 4322, and the frame body 4321 is connected to the wheel body 431. Each of the first seal 44 and the particle seal 45 is provided between the shaft 41 and the frame body 4321. The outer end of the first spacer ring 4322 is connected to the frame body 4321, and the inner end of the first spacer ring 4322 is adjacent to the shaft 41 or the inner end of the first spacer ring 4322 abuts against the shaft 41. The particle seal 45 is axially located between the first seal 44 and the first spacer ring 4322 on the shaft 41. The first spacer ring 4322 is provided with a receiving groove 4323, and at least a part of the bent section 452 is located in the receiving groove 4323.

[0049] Thus, the structure of the idler 4 can be made more compact and more reasonable. Moreover, the first spacer ring 4322 can intercept a part of impurities such as particles and dust, so that not only can the service life of the first seal 44, the bearing 42 and the idler 4 be further improved, but also the maintenance times and maintenance costs of the idler 4 can be further reduced, and the running time of the idler 4 can be further extended.

[0050] Optionally, the particle seal 45 abuts against each of the first seal 44 and the first spacer ring 4322. Thereby, the sealing effect of the particle seal 45 can be further improved, so that the particle seal 45 can more effectively intercept impurities such as particles and dust, which can not only further improve the service life of the first seal 44, the bearing 42 and the idler 4, but also further reduce the maintenance frequency and maintenance cost of the idler 4 and further extend the running time of the idler 4.

[0051] As Figure 5 shown, the idler 4 of the unloading station further includes a second seal 46, and the second seal 46 is arranged between the support 432 and the spacer 412. For example, the second seal 46 is arranged between the frame body 4321 and the ring body 4121 of the spacer 412. The second seal 46 has a particle receiving cavity, and the particle seal 45 is axially located between the first seal 44 and the second seal 46 on the shaft 41.

[0052] Thereby, the second seal 46 can be used to intercept impurities such as particles and dust, so as to further prevent impurities from adhering to the first seal 44 and further wearing the first seal 44. Thereby, not only can the service life of the first seal 44, the bearing 42 and the idler 4 be further improved, but also the maintenance frequency and maintenance cost of the idler 4 can be further reduced and the running time of the idler 4 can be further extended.

[0053] Optionally, the second seal 46 is a flocked seal.

[0054] As Figure 5 shown, the spacer 412 includes a ring body 4121 and a second spacer ring 4122. The ring body 4121 is sleeved on the shaft body 411. The inner end of the first spacer ring 4322 is adjacent to the ring body 4121 or the inner end of the first spacer ring 4322 abuts against the ring body 4121. The inner end of the second spacer ring 4122 is connected to the ring body 4121, and the outer end of the second spacer ring 4122 is adjacent to the frame body 4321 or the outer end of the second spacer ring 4122 abuts against the frame body 4321. The particle seal 45 is axially located between the first seal 44 and each of the first spacer ring 4322 and the second spacer ring 4122 on the shaft 41.

[0055] Thereby, the structure of the idler 4 can be made more reasonable. The second spacer ring 4122 can intercept a part of impurities such as particles and dust, which can not only further improve the service life of the first seal 44, the bearing 42 and the idler 4, but also further reduce the maintenance frequency and maintenance cost of the idler 4 and further extend the running time of the idler 4.

[0056] As Figure 5As shown, the first spacer ring 4322 and the second spacer ring 4122 are arranged at an axial interval along the axis 41, and the second seal 46 is axially located between the first spacer ring 4322 and the second spacer ring 4122 on the axis 41. Thus, the second seal 46 can be installed more stably, making the structure of the idler 4 more compact and more reasonable. Moreover, the first spacer ring 4322 and the second spacer ring 4122 can intercept a part of impurities such as particles and dust, so that not only the service life of the first seal 44, the bearing 42 and the idler 4 can be further improved, but also the maintenance times and maintenance costs of the idler 4 can be further reduced, and the running time of the idler 4 can be further extended.

[0057] Optionally, the second seal 46 abuts against each of the first spacer ring 4322 and the second spacer ring 4122. Thus, the sealing effect of the second seal 46 can be further improved, so that the second seal 46 can more effectively intercept impurities such as particles and dust, so that not only the service life of the first seal 44, the bearing 42 and the idler 4 can be further improved, but also the maintenance times and maintenance costs of the idler 4 can be further reduced, and the running time of the idler 4 can be further extended.

[0058] As Figure 5 shown, each of the first seal 44, the particle seal 45 and the second seal 46 is arranged between the ring body 4121 and the frame body 4321. The first seal 44, the particle seal 45, the first spacer ring 4322, the second seal 46 and the second spacer ring 4122 are arranged in sequence along the axial direction of the axis 41.

[0059] Those skilled in the art can understand that the idler 4 may further include a static seal. The static seal may be known and has nothing to do with the novel points of the present application, so it will not be described in detail.
