Description

Technical Field

[0001] The present application belongs to the technical field of cargo transportation systems, and specifically relates to an aerial rail transportation system. Background Art

[0002] Bulk cargo, such as mineral resources, needs to be transferred from storage yards or warehouses to railway stations and then transported by rail vehicles. Currently, the commonly used bulk cargo transportation methods include road systems, belt systems, and chutes.

[0003] Although road transportation has the characteristics of mobility, rapid turnover, and strong adaptability to terrain conditions, its carrying capacity is small, the transportation cost is high, and the transportation safety is poor in mountainous areas and harsh climatic conditions.

[0004] Belt conveyor systems are mature technologies and have been widely used both domestically and internationally. They offer advantages such as strong line adaptability, low engineering implementation difficulty, environmental friendliness and resource conservation, large and relatively stable transport volumes, and continuous, all-weather transportation unaffected by weather. However, due to the unique characteristics of coal sources and coal products, the use of coal corridors for transport is inflexible. Coal products must be operated in separate time periods, and large-capacity coal silos and screening systems must be constructed at both ends of the belt loading and unloading area and in the middle of certain varieties to facilitate separate coal discharge. Increasing investment in coal corridor projects also increases the difficulty of managing the transportation process and coal sales. Furthermore, problems such as fires or belt tears during transportation in coal corridors can significantly impact coal sales.

[0005] Chutes are generally used for short-distance transportation, relying on gravity to accelerate objects downward. They are primarily used in small open-pit mines. In large and medium-sized open-pit mines, chutes are often used in conjunction with chutes. When transporting coal, chutes have specific requirements for particle size, moisture content, chute inclination, and length. Generally speaking, the particle size should not be too large. A larger particle size increases the required diameter of the chute pipe, the project workload, and the design of foundations with large inclination angles becomes more difficult. The pipe diameter is generally required to be six times the maximum particle size. At the same time, the particle size should not be too small, as this can easily cause pipe blockage. Regarding moisture content, long-distance chutes (≥100m) generally do not contain much water. Regarding chute inclination, the preferred angle for long-distance chutes (≥100m) is between 25° and 55°. Experience with tunnel slag transportation shows that an angle less than 25° is prone to pipe blockage. An angle greater than 55° makes the slag flow rate uncontrollable, resulting in excessive pipe wear and significant impact loads on the structure, making the design more difficult. Regarding chute length, current design experience suggests it should be less than 1500m. Flow rates in oversized chutes are extremely difficult to control, which can easily lead to blockage or excessive pipe wear. Furthermore, chute wear is strongly correlated with transport volume. For bulk transport using gravitational potential energy, flow rates are typically controlled between 8m / s and 12m / s. At these speeds, pipe wear is relatively rapid, strongly correlated with transport volume.

[0006] Therefore, the existing technology lacks a cargo transportation system that can meet the requirements of long-distance, steep slope, and large-volume transportation in harsh environments. Summary of the Invention

[0100] In order to enable those skilled in the art to understand the present application more clearly, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of this application.

[0101] The first embodiment of the present application provides an aerial rail transport system 1000, which is used to connect the cargo production area and the railway station to transport the cargo in the cargo production area to the railway vehicles of the railway station. The cargo in the cargo production area can be stacked in the cargo production area, such as the produced sugar is stacked in the product warehouse; it can also be cargo output after pre-processing, such as the cargo output from the coal mining area is coal output from the coal preparation plant. The cargo production area is not limited to mining areas (coal mines, iron mines, etc.) and sugar production areas, and the produced cargo is bulk cargo, so the aerial rail transport system 1000 is required to meet the bulk cargo loading and unloading requirements.

[0102] See also Figure 1The aerial rail transportation system 1000 provided in the embodiment of the first aspect of the present application includes seven main functional units: a carrier unit 100, a rail system 200, a collection vehicle 300, a quick-loading system 400, an unloading unit, a traction and power supply system, and a control system. Among them: the carrier unit 100 is used to transport goods, and its structure can be a container, an ordinary open cargo box, a hopper container, a funnel structure, etc., which is not limited by this application. The collection vehicle 300 is connected to the carrier unit 100, and a hanging connection method or a bottom-supporting connection method can be adopted, which is not limited by this application. The rail system 200 is arranged between the cargo production area and the railway station for the collection vehicle 300 to travel back and forth between the cargo production area and the railway station to transfer the carrier unit 100. The quick-loading system 400 is used to load the goods in the cargo production area into the carrier unit 100, and the quick-loading system 400 can adopt a mature railway quick-loading system. The carrier unit 100 can be connected to the transport vehicle 300 when loading goods, that is, the carrier unit 100 and the transport vehicle 300 are an integral structure and always remain connected during operation; the carrier unit 100 can also be detached from the transport vehicle 300 when loading goods, and then connected to the transport vehicle 300 after loading. The unloading unit is used to transfer the goods and / or the carrier unit 100 from the rail system 200 to the railway station. The electric energy required for the operation of the transport vehicle 300 is provided by the traction and power supply system. The electric energy provided by the traction and power supply system generates traction to drive the transport vehicle 300 on the one hand, and is used to power the electrical equipment on the transport vehicle 300 on the other hand. The control system controls the operation of the transport vehicle 300, the quick-installation system 400 and the unloading unit.

[0103] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 19 , the operation process of the aerial rail transportation system 1000 is:

[0104] The cargo in the cargo production area is loaded into the empty transport unit 100 through the quick loading system 400; the traction and power supply system drives the transport vehicle 300 to move along the track system 200, and the transport vehicle 300 drives the loaded transport unit 100 to move to the unloading unit; the unloading unit transfers the loaded transport unit 100 and / or the cargo loaded by the transport unit 100 to the railway station; the empty transport unit 100 after unloading or the empty transport unit 100 stacked in the yard is driven by the transport vehicle 300 and moves along the track system 200 to the cargo production area.

[0105] In the above operation process, in some embodiments, the empty carrier unit 100 (referred to as "empty box") and the loaded carrier unit 100 (referred to as "loaded box") are switched on the track, that is, the carrier unit 100 and the collective moving vehicle 300 are not separated throughout the whole process, and the carrier unit 100 is always running on the track and transferred to the opposite side through the transfer track. Figure 1 In some embodiments, the track system 200 is a closed loop structure, including a cargo production area side transfer section 201 close to the cargo production area, a railway station side transfer section 202 close to the railway station, and an empty vehicle transport section 203 and a loaded vehicle transport section 204 connected to the cargo production area side transfer section 201 and the railway station side transfer section 202. The transport units 100 connected to the collective transport vehicles 300 running on the empty vehicle transport section 203 are in an empty state, and the transport units 100 connected to the collective transport vehicles 300 running on the loaded vehicle transport section 204 are in a loaded state. Figure 1 and Figure 4 In some embodiments, the empty vehicle transport section 203 and the heavy vehicle transport section 204 are arranged in parallel, so that the lengths of the empty vehicle transport section 203 and the heavy vehicle transport section 204 are basically the same, which facilitates the control of the operating speeds of the collection vehicle 300 connected to the empty boxes (referred to as "empty vehicles") and the collection vehicle 300 connected to the heavy boxes (referred to as "heavy vehicles") through the control system.

[0106] In some embodiments, the aerial rail transportation system 1000 is applied in a scenario where there is a large altitude difference between the upstream and downstream, for example, the cargo production area is a mine with an altitude of 2500m; the railway station is relatively low at an altitude of 650m. Then the altitude of the cargo production area side transfer section 201 is greater than the railway station side transfer section 202. In order to save energy, in some embodiments, the aerial rail transportation system 1000 adopts an "empty car uphill, heavy car downhill" operation control scheme, that is: the collection vehicle 300 running on the empty vehicle transport section 203 runs uphill, and transfers the empty carrier unit 100 from the railway station side transfer section 202 to the cargo production area side transfer section 201; the collection vehicle 300 running on the heavy vehicle transport section 204 runs downhill, and transfers the loaded carrier unit 100 from the cargo production area side transfer section 201 to the railway station side transfer section 202. The heavy vehicle running downhill can use its own weight to save traction power.

[0107] Both empty and loaded vehicles are provided with traction power by the traction and power supply system. Figure 16 In some embodiments, the traction and power supply system includes a bidirectional traction converter system, a downhill traction system, and an uphill traction system. The bidirectional traction converter system is connected to an AC high-voltage busbar and a DC high-voltage busbar. The AC high-voltage busbar is used to connect to a traction substation. The AC high-voltage power (e.g., AC35kV) on the AC high-voltage busbar is converted into DC high-voltage power (e.g., DC1500V) by the bidirectional traction converter system. Both the downhill traction system and the uphill traction system draw power from the DC high-voltage busbar. The downhill traction system is used to supply power to heavy vehicles, while the uphill traction system is used to supply power to empty vehicles.

[0108] When a heavy vehicle is going downhill, the vehicle's gravitational potential energy is converted into vehicle kinetic energy. When the vehicle is going downhill to maintain a constant speed or brake, the traction system needs to work under the electric braking condition to provide a force to the vehicle to prevent the vehicle from accelerating or running. At this time, the traction system in the downhill section is in the power generation state and can feed back electric energy to the DC high-voltage bus to increase the DC high-voltage bus voltage. This electric energy can provide traction power to the empty vehicle running in the opposite direction through the DC high-voltage bus. When the DC high-voltage bus voltage rises to the upper limit of the DC bus voltage, the bidirectional traction converter system works and feeds back the excess electric energy to the AC high-voltage bus side through rectification and inversion. It can provide electric energy to other traction substations through the AC high-voltage bus ring network, such as Figure 16 shown.

[0109] Considering that the collective vehicle 300 and / or the carrier unit 100 may fail during use, and that the collective vehicle 300 and / or the carrier unit 100 need to be inspected daily during normal use, please refer to Figure 1 and Figure 19 In some embodiments, the rail system 200 is provided with a storage line 205 for storing the collective vehicle 300 and / or the transport unit 100, a maintenance area 206 for repairing the collective vehicle 300 and / or the transport unit 100, and a train inspection area 207 for inspecting the transport unit 100 and / or the transport unit 100. Since heavy vehicles are loaded with cargo, it is inconvenient to stop for maintenance and inspection. In some embodiments, the storage line 205, the maintenance area 206, and the train inspection area 207 are all located in the empty vehicle transport section 203. Please refer to Figure 1 The storage line 205, maintenance area 206 and train inspection area 207 are all track sections parallel to the track of the empty car transport section 203. A switch is set at the entrance end so that the collective vehicle 300 can drive to the switch and can choose to continue driving along the empty car transport section 203, or drive into the storage line 205, maintenance area 206 or train inspection area 207.

[0110] See also Figure 15 In some embodiments, the train inspection area 207 has a total of 6 maintenance parking spaces, which can accommodate 6 train vehicles 300 for train inspection at a time; the maintenance area 206 has a total of 8 maintenance parking spaces, which can accommodate 8 train vehicles 300 for maintenance at a time. The scope of tasks of the train inspection area 207: (a) undertake the daily inspection of the ASR vehicles in operation; (b) undertake the temporary parking of the ASR maintenance vehicles. The scope of tasks of the maintenance area 206: (a) undertake the daily maintenance of the ASR vehicles in operation; (b) undertake the upgrading, testing, and commissioning of the ASR vehicles.

[0111] See also Figure 1 and Figure 19In some embodiments, the storage lane 205, maintenance area 206, and train inspection area 207 are all located near the cargo production area, that is, before the loading point of the aerial rail vehicle. This is where the aerial rail transportation system is used to manage the operation, parking, conversion, testing, maintenance, and repair of the aerial rail vehicle (collection vehicle 300). After the collection vehicle 300 passes the train inspection / repair, it is transported to the quick loading system 400 for loading. This ensures stable operation of the vehicle under load and reduces the probability of failure of the loaded vehicle.

[0112] To do this, see Figure 1 and Figure 19 In some embodiments, both the empty vehicle transport section 203 and the loaded vehicle transport section 204 are provided with one or more fault stop lines 208. A faulty collective vehicle 300 or a collective vehicle 300 connected to a faulty transport unit 100 will move to the fault stop line 208. The fault stop line 208 is a track section parallel to the track of the empty vehicle transport section 203. A switch is provided at the entrance end, so that the collective vehicle 300 can drive to the switch and can choose to continue driving along the empty vehicle transport section 203 or drive into the fault stop line 208. The faulty collective vehicle 300 can drive into the fault stop line 208 by itself, or it can be towed by a normally running collective vehicle 300. Please refer to Figure 7 and Figure 9 In some embodiments, the collective vehicle 300 is equipped with a coupler buffer device 360, which has the same structure as a coupler buffer device on a railway vehicle. By setting up a fault stop line 208, when the aerial rail transportation system 1000 adopts a cycled production, the departure time, driving speed, and stop time of each collective vehicle 300 are pre-set by the program. If a running collective vehicle 300 and / or carrier unit 100 fails, the collective vehicle 300 can be transferred to the fault stop line 208 to avoid affecting the operation of subsequent vehicles.

[0113] The number of fault stop lines 208 depends on the length of the track system 200. The spacing between two adjacent fault stop lines 208 is approximately equal. For example, a fault stop line 208 is set every 3 km. In some embodiments, the locations of the fault stop lines 208 on the heavy vehicle transport section 204 correspond to those on the empty vehicle transport section 203. That is, if a fault stop line 208 is set at a certain location on the heavy vehicle transport section 204, a fault stop line 208 is also set at the corresponding location on the empty vehicle transport section 203. In some embodiments, the quick assembly system 400 is located opposite the storage line 205 to handle faulty vehicles. One of the fault stop lines 208 on the heavy vehicle transport section 204 is close to the quick assembly system 400 and opposite the maintenance area 206 and / or the train inspection area 207. Since the maintenance area 206 and the train inspection area 207 can also park faulty vehicles, they can be considered as replacements for the fault stop lines 208.

[0114] The fault stop line 208, the storage line 205, the maintenance area 206 and the train inspection area 207 are all track branches of the track system 200. They can adopt closed track branches, that is, the vehicle enters the track branch forward and exits the track branch forward; they can also adopt open track branches, that is, the vehicle enters the track branch forward and reverses to exit the track branch backward. A turnout is required at the connection between the track branch and the main track of the track system 200. The closed track branch requires two sets of turnout structures, while the open track branch only requires one set of turnout structures, which is lower in cost. The specific branch structure of the fault stop line 208, the storage line 205, the maintenance area 206 and the train inspection area 207 can be determined according to actual needs, and this application does not impose any restrictions.

[0115] See also Figure 4 and Figure 5 , shows a schematic structural diagram of the track system of an aerial rail transportation system. In certain embodiments, the track system 200 includes a pier 210 and a track beam 220 disposed on the pier 210. Track branches such as the fault stop line 208, the storage line 205, the maintenance area 206, and the train inspection area 207 are connected to the track beam 220 via switches. The pier 210 includes a corbel assembly 211 and a support 212 disposed on the corbel assembly 211. Two corbel assemblies 211 are provided, and the two corbel assemblies 211 are spaced apart along the width direction of the track beam 220. The track beam 220 includes a closed box beam 221, two rails 222 disposed outside and on both sides of the closed box beam 221, and a support portion 223 disposed on the top of the closed box beam 221. The support portion 223 is disposed on the support 212.

[0116] In the prior art, the track beams of the hollow rail system mostly adopt open beams. For open beams, the pressure of the running wheels is an eccentric load, and the fatigue performance is poor, which leads to an increase in the annular reinforcement ribs of the track beam and the stiffening ribs at the bottom of the running surface, and a lot of invalid weight. In addition, the wear and corrosion of the running surface will cause the running plate to become thinner and cannot be repaired. In addition, the lower opening structure of the open beam leads to a smaller beam body stiffness, which is not conducive to size control. In some embodiments, the beam body of the track beam 220 adopts a closed box beam 221. Compared with the existing open beam, the closed box beam 221 has higher strength, stiffness and stability, and can adapt to the harsh environment of large transportation capacity (rated load: 32t), large ramp (maximum ramp 80‰), and large temperature difference (ambient temperature -25.5℃~48℃).

[0117] In some embodiments, please combine Figure 5The corbel assembly 211 includes a pillar 213 and a corbel 214, the support 212 is arranged on the corbel 214, the top end of the pillar 213 is an integrated structure or fixedly connected to the pier 210, and the bottom end of the pillar 213 is detachably connected to the corbel 214; or, the top end of the pillar 213 is detachably connected to the pier 210, and the bottom end of the pillar 213 is fixedly connected to the corbel 214.

[0118] In some embodiments, both pillars 213 and piers 210 are constructed of steel, forming an integral structure. This structure provides greater strength than separate welded structures. In some embodiments, pillars 213 and piers 210 are integrally cast with concrete, providing a fixed connection between them. This integrally cast concrete structure offers low cost and improved economics.

[0119] See also Figure 6 In some embodiments, a reinforcement assembly 224 is provided at the bottom of the closed box beam 221. The bottom plate of the closed box beam 221 extends outward to form a track mounting plate. The track is provided on the upper surface of the track mounting plate, and the reinforcement assembly 224 is provided on the lower surface of the bottom plate. The reinforcement assembly 224 includes a longitudinal reinforcement portion 225 and a transverse reinforcement portion 226. The longitudinal reinforcement portion 225 and the transverse reinforcement portion 226 are interconnected and arranged at an angle to enclose a cavity structure 227 with an opening. The provision of the reinforcement assembly 224 improves the axial and width strength of the track mounting plate, enhances the torsion resistance of the track beam 220, and improves safety. Since the track beam 220 is provided with a track, the structure for fixing the track needs to be inspected and maintained. The cavity structure 227 enclosed by the longitudinal reinforcement and the transverse reinforcement portion 226 not only improves the transverse strength and longitudinal strength of the track beam 220 and its ability to resist torsion, but also forms an inspection port for the fixed structure to facilitate maintenance of the track.

[0120] In some embodiments, please combine Figure 4 and Figure 5 Two support portions 223 are provided, one at each axial end of the closed box beam 221, connecting the track beam 220 to the pier 210. In some embodiments, the support portions 223 are corbels 214 connected to both sides of the closed box beam 221 in the width direction. In other embodiments, the support portions 223 are crossbeams symmetrically disposed at the top of the closed box beam 221. The width of the crossbeams is greater than the width of the top plate of the closed box beam 221, thereby reducing stress concentration at the connection between the crossbeams and the closed box beam 221.

[0121] The aerial rail transportation system 1000 provided in the embodiment of the present application can realize three unloading and transportation modes at the cargo unloading end: bulk cargo unloading and transportation, carrier unit 100 unloading and transportation, and "bulk cargo + carrier unit" unloading and transportation. That is, the case where the unloading unit is used to transfer cargo from the rail system 200 to the railway station corresponds to the two unloading and transportation modes of bulk cargo unloading and transportation and "bulk cargo + carrier unit" unloading and transportation. The case where the unloading unit is used to transfer the carrier unit 100 from the rail system 200 to the railway station corresponds to the two unloading and transportation modes of carrier unit 100 unloading and transportation and "bulk cargo + container" unloading and transportation. In some embodiments, the unloading unit can be used only to transfer cargo from the rail system 200 to the railway station; in some embodiments, the unloading unit can be used only to transfer the carrier unit 100 from the rail system 200 to the railway station; in some embodiments, the unloading unit can be used to transfer both cargo and carrier unit 100 from the rail system 200 to the railway station.

[0122] See also Figure 2 When the unloading unit is used to transfer cargo from the rail system 200 to the railway station, the unloading unit includes an unloading bin 700, cargo transportation equipment 800, and a loading system 900 that are connected in sequence. Since the unloading bin 700 and the quick loading system 400 are both connected to the heavy vehicle, the unloading bin 700 and the quick loading system 400 are both located in the heavy vehicle transportation section 204. In some embodiments, the unloading bin 700 is a warehouse built on the ground. The load box of the collective moving vehicle 300 moves above the unloading bin 700, and the bulk cargo is unloaded into the unloading bin 700 through a buffer bucket. In some embodiments, the unloading bin 700 is a coal receiving pit built on the ground or excavated on the ground. The load box of the collective moving vehicle 300 moves above the coal receiving pit, and the carrier unit 100 unloads the bulk cargo directly into the coal receiving pit.

[0123] The bulk cargo in the unloading bin 700 is transferred to the loading system 900 via cargo transport equipment 800. Loading system 900 is located at the railway station and is used to load the bulk cargo onto railway vehicles. Cargo transport equipment 800 can be a conventional bulk cargo transfer device such as a belt conveyor or chute, and the specific structure is not limited in this application. In some embodiments, loading system 900 utilizes a rapid quantitative loading system, such as the rapid quantitative coal loading system used in coal mining areas. The specific structure can be referenced to the relevant disclosures in the prior art and is not limited in this application.

[0124] See also Figure 19In certain embodiments, an unloading unit is used to transfer cargo from the rail system 200 to a railway terminal. The unloading unit includes a sequentially docked cargo transport device 800 and a loading system 900. The cargo transport device 800 includes several product bins and a belt conveyor for transporting cargo. Because both the cargo transport device 800 and the quick loading system 400 are docked with heavy-duty vehicles, they are both located in the heavy-duty vehicle transport section 204. The containerized vehicle 300 moves over the product bins, and the transport unit 100 unloads the bulk cargo directly into the product bins.

[0125] When the unloading unit realizes the bulk cargo unloading transportation mode, the carrier unit 100 is required to be able to realize bulk cargo packing and unloading. In some embodiments, the carrier unit 100 adopts a standard carrier unit 110, see Figure 10 The standard transport unit 110 includes a box body 111, and at least one bottom door assembly 112 and at least one bottom door opening and closing assembly 113 mounted on the bottom of the box body 111. The box body 111 is open at both the top and bottom, with the top of the box body 111 open to accommodate cargo loading. Multiple funnel ridges 114 are spaced apart at the bottom of the box body 111. The area of ​​the bottom surface of the box body 111 not covered by the funnel ridges 114 constitutes a discharge port 115, through which cargo falls during unloading. The bottom door opening and closing assembly 113 is mounted on the bottom of the box body 111, below the funnel ridges 114. The funnel ridges 114 shield the bottom door opening and closing assembly 113, preventing bulk cargo from falling onto the bottom door opening and closing assembly 113. Bottom door assembly 112 is mounted at the bottom of container 111 and corresponds to discharge port 115. Bottom door assembly 112 opens or closes discharge port 115 under the action of bottom door opening and closing assembly 113. The specific structures of bottom door assembly 112 and bottom door opening and closing assembly 113, as well as the opening and closing method of bottom door opening and closing assembly 113, can be referenced to hopper containers or railway hopper cars in the prior art and will not be described in detail here.

[0126] See also Figure 10 In some embodiments, the carrier unit 100 further includes a cubic frame 116, the box body 111 is installed on the upper part of the cubic frame 116, and the bottom door assembly 112 and the bottom door opening and closing assembly 113 are both located inside the cubic frame 116, so that the lower area of ​​the entire cubic frame 116 is an empty area, providing movement space for the bottom door assembly 112 and the bottom door opening and closing assembly 113, and ensuring that the bottom door assembly 112 and the bottom door opening and closing assembly 113 have a certain distance from the outside world, protecting the bottom door assembly 112 and the bottom door opening and closing assembly 113 from being damaged by foreign objects or accidentally opened.

[0127] The cubic frame 116 is connected to the container transport vehicle 300. In some embodiments, the transport unit 100 is suspended from the bottom of the container transport vehicle 300. Corner fittings 117 are provided on the upper portion of the cubic frame 116. The corner fittings 117 of the cubic frame 116 cooperate with the lifting device of the container transport vehicle 300. The specific structure can be referred to as the container lifting structure. In some embodiments, the transport unit 100 is fixed using a bottom support method. The lower portion of the cubic frame 116 is provided with locking members (such as corner fittings 117 or support plates). The body of the container transport vehicle 300 is hooked to the bottom of the cubic frame 116 to support the entire transport unit 100.

[0128] See also Figure 3 In some embodiments, when the unloading unit is used to transfer the carrier unit 100 from the rail system 200 to the railway station, the unloading unit includes a fixed transfer system 500. The fixed transfer system 500 has the function of lifting the carrier unit 100 and can cooperate with a heavy forklift, rail crane, or reach stacker to achieve the transfer of the carrier unit 100.

[0129] See also Figure 11 The fixed loading and unloading system 500 includes a running device 510, a telescopic support 520, and a lower platform 530. The lower end of the telescopic support 520 is connected to the running device 510, and the upper end of the telescopic support 520 is connected to the lower platform 530. The lower platform 530 is used to support the carrier unit 100. The running device 510 can adopt a motor-driven universal wheel or a motor-driven steel wheel and rail mechanism. The running device 510 can drive the telescopic support 520 and the lower platform 530 to move axially along the track beam 220 to dock with the container transport vehicle 300. The telescopic support 520 drives the lower platform 530 to rise and fall. When the lower platform 530 rises to contact the loaded box connected to the container transport vehicle 300, the container transport vehicle 300 disconnects from the loaded box, and the lower platform 530 with the loaded box descends. The lower platform 530 rises with an empty box, and the empty box connects to the container transport vehicle 300. Then, the lower platform 530 descends to its initial state.

[0130] See also Figure 11In some embodiments, the fixed changing system 500 further includes an upper platform 540 and a fine-tuning mechanism 550. The upper platform 540 is movably mounted on the lower platform 530. To facilitate movement of the upper platform 540, a universal ball joint may be provided between the upper and lower platforms 540 and 530. The fine-tuning mechanism 550 is disposed on the lower platform 530 and is force-transmittingly connected to the upper platform 540. The fine-tuning mechanism 550 is capable of fine-tuning the position of the upper platform 540. The fine-tuning mechanism 550 may employ a linear telescopic mechanism such as a telescopic cylinder or a motor-driven ball screw. The specific structure is not limited in this application. In some embodiments, the fine-tuning mechanism 550 is capable of fine-tuning both the lateral (perpendicular to the track beam 220) and longitudinal (parallel to the track beam 220) positions of the upper platform 540. The fine-tuning mechanism 550 is provided in at least two groups, with at least one group of the fine-tuning mechanisms 550 extending in the lateral direction and at least one group of the fine-tuning mechanisms 550 extending in the longitudinal direction. The upper platform 540 is used to carry the carrier unit 100. In some embodiments, a plurality of limiting structures 560 are provided on the upper platform 540 to limit the carrier unit 100 placed thereon.

[0131] See also Figure 3 The unloading unit also includes a container truck, which circulates between the fixed transshipment system 500 and the railway station to transfer the carrier unit 100. To cooperate with the fast loading system 400 for online loading, in some embodiments, the carrier unit 100 is a container 120 with an open top. The fixed transshipment system 500 can meet the continuous transshipment requirements of various types of standard containers or bulk loading units by performing transshipment with the transport vehicle 300. Figure 12 When the fixed loading and unloading system 500 is loading and unloading containers, the whole machine is placed flat on the ground, with the longitudinal direction parallel to the track beam 220 of the track system 200. The heavy forklift lifts the container and places it directly above the upper platform 540 of the fixed loading and unloading system 500. Figure 12 (a) As shown; the fixed transshipment system 500 fine-tunes the position of the upper platform 540 by the fine-tuning mechanism 550, so that the locks of the container 120 and the set movement vehicle 300 are aligned, as shown Figure 12 (b) shown; by fixing the retractable support 520 of the transshipment system 500 to lift the container and the set movement vehicle 300 to complete the docking work of the container 120, as shown Figure 12 (c) shown.

[0132] In some embodiments, the aerial rail transportation system 1000 further includes a mobile transfer system for docking the quick-installation system 400 and the integrated transport vehicle 300. Figure 13, shows a structural schematic diagram of the mobile changing system 600. The mobile changing system 600 is provided with more than two limiting structures 650 for placing the transport unit 100. The empty box and the loaded box are respectively arranged in different limiting structures 650. The mobile changing system 600 moves to move the empty box to the bottom of the quick loading system 400, and the loaded box is moved to the bottom of the transport vehicle 300 at the same time.

[0133] See also Figure 13 In some embodiments, the mobile changing system 600 includes a changing track 610, a running mechanism 620, a telescopic support 630 and a limiting platform 640. The changing track 610 is set at an angle to the track system 200. The running mechanism 620 can move along the changing track 610 to dock with the quick-changing system 400 or the integrated moving vehicle 300. The lower end of the telescopic support 630 is connected to the running mechanism 620, and the upper end is connected to the limiting platform 640. The limiting platform 640 is used to support the carrying unit 100, and the limiting structure 650 is set on the limiting platform 640.

[0134] See also Figure 14 In some embodiments, the quick-loading system 400 has two loading positions, one on the left and one on the right, with the track system 200 passing through the two loading positions. The mobile changing system 600 is provided with two limiting structures 650, which can simultaneously carry two carrier units 100. The running mechanism 620 drives the mobile changing system 600 as a whole to switch between the first loading position 401 and the second loading position 402 along the changing track 610. When the mobile changing system 600 is at the first loading position 401, it connects to the left loading position and the track system 200; when the mobile changing system 600 is at the second loading position 402, it connects to the right loading position and the track system 200.

[0135] See also Figure 14 Taking bulk coal transportation as an example, the workflow of the mobile loading system 600 for bulk cargo loading is as follows:

[0136] 1) The container transport vehicle 300 carries an empty container and stops at the bulk cargo loading area; the induction switch on the mobile loading and unloading system 600 detects the parking position of the container transport vehicle 300, and the running mechanism 620 of the mobile loading and unloading system 600 drives the mobile loading and unloading system 600 to move slightly (generally ≤300mm) along the running direction of the container transport vehicle 300 until the center line of the container transport vehicle 300 and the mobile loading and unloading system 600 are aligned. Figure 14 As shown in A;

[0137] 2) The telescopic support 630 of the mobile loading and unloading system 600 lifts the limiting platform 640 as a whole (at this time, a loaded box loaded with coal is already in the limiting structure 650 on the right side of the limiting platform 640), driving the empty box on the moving vehicle 300 and the loaded box on the right side to rise together. Figure 14 B;

[0138] 3) The running mechanism 620 of the mobile reloading system 600 drives the limiting platform 640 and the two transport units 100 to move horizontally as a whole until the heavy box (right side) enters the original empty box position of the moving vehicle 300, and the original empty box (left side) reaches the left coal loading position. During the movement of the running mechanism 620 of the mobile reloading system 600, the antifreeze liquid is sprayed on the inner surface of the empty box (at low temperature), and the dustproof liquid is sprayed on the top surface of the heavy box. Figure 14 As shown in C;

[0139] 4) The telescopic support 630 of the mobile loading system 600 lifts the limit platform 640 and lowers it as a whole, completing the unloading of the loaded container and the empty container falling into the coal loading position, as shown in the following figure. Figure 14 As shown in D;

[0140] 5) The moving vehicle 300 carries the loaded container and drives away; the quantitative bin 410 in the middle of the left coal loading and unloading equipment is slightly moved longitudinally to the appropriate position (this step can also be completed simultaneously in step 1), and the telescopic funnel at the bottom extends below the top surface of the carrier unit 100, and begins to move longitudinally while leaking coal until the coal is fully loaded and the funnel is retracted. Figure 14 As shown in E;

[0141] 6) The next container truck 300, carrying an empty container, stops at the bulk cargo loading area, and the loading and unloading area enters the next cycle, such as Figure 14 As shown in F.

[0142] In some embodiments, the collective motion vehicle 300 is driven by a linear motor, the stator 230 of the linear motor is located at the bottom of the track beam 220 and is electrically connected to the traction and power supply system, and the mover 350 of the linear motor is located on the collective motion vehicle 300. Figure 7 、 Figure 8 and Figure 9 In some embodiments, the integrated vehicle 300 includes a bogie assembly 310, a frame assembly 320, and a suspension assembly 330. The suspension assembly 330 is connected between the bogie assembly 310 and the frame assembly 320, allowing relative shaking between the bogie assembly 310 and the frame assembly 320, and can withstand a force 11 wind. The bogie assembly 310 is used to install the mover 350 of the linear motor (with a gap of about 10 mm from the stator 230). The mover 350 of the linear motor cooperates with the stator 230 to provide traction for the movement of the bogie assembly 310. The bogie assembly 310 is provided with a wheel assembly 313, which moves along the two rails 222 of the track beam 220. The frame assembly 320 is used to connect to the carrier unit 100. Please refer to Figure 7 and Figure 9 In some embodiments, the bogie assembly 310 is provided with a brake device 380 for decelerating and braking when going downhill. Figure 7 and Figure 9In some embodiments, a power supply device 370 is provided on the bogie assembly 310. The power supply device 370 uses sliding contact to obtain power and contacts the power receiving rail on the track beam 220. The power receiving rail is connected to the traction power supply system to supply power to the electrical equipment on the collective vehicle 300 (non-traction power).

[0143] The wheels in the wheel assembly 313 can be rubber wheels or steel wheels. In some embodiments, the wheels in the wheel assembly 313 are steel wheels. Steel wheels have a long service life and low maintenance costs. Especially for application scenarios with high transport capacity requirements, the integrated vehicle 300 adopts a suspended transport method. At the same time, it is not restricted by wheel-rail adhesion, and can achieve large slopes (maximum slope 80‰) climbing of the integrated vehicle 300. Therefore, steel wheels can better meet market demand. In addition, compared to rubber wheels (the maximum continuous running time of a single test is 30 minutes, and the heat dissipation is 5 minutes, otherwise there will be a risk of rubber cracking, peeling or falling off), steel wheels can adapt to large transport capacity (rated load: 32t), large temperature difference (ambient temperature -25.5℃~48℃) and long distance (one-way 66km) transportation requirements. The running speed of steel wheels can reach 50~60km / h, and the running speed of rubber wheels is generally less than 40km / h.

[0144] See also Figure 7 In certain embodiments, when the frame assembly 320 is connected to the top of the carrier unit 100, the carrier unit 100 is suspended. For example, if the carrier unit 100 uses a container 120 with an open top, the frame assembly 320 is equipped with a twist lock assembly that cooperates with the top corner fittings of the container 120 to lock the container 120. This method of locking the container 120 with the twist lock assembly facilitates loading and unloading of the container 120, but poses certain safety risks during long-distance transportation.

[0145] See also Figure 9 In some embodiments, when the frame assembly 320 is connected to the bottom of the carrier unit 100, the carrier unit 100 is fixed in a bottom-supporting manner. The frame assembly 320 has two supporting brackets 322. Both supporting brackets 322 are provided with a rotating lock device, which cooperates with the corner pieces at the bottom of the carrier unit 100. Since the carrier unit 100 is placed on the two supporting brackets 322 as a whole, it is equivalent to the two supporting brackets 322 wrapping the carrier unit 100. Compared with the hanging fixing method, the bottom-supporting fixing method is used to fix the carrier unit 100. It is safer and more suitable for long-distance transportation, and can withstand harsh environments with high wind volume and strong sandstorms. The bottom-supporting fixing method is used to fix the carrier unit 100, and it is necessary to use external adapter equipment to load and unload the carrier unit 100. Figure 9Taking the shown transport vehicle 300 as an example, when unloading the transport unit 100, the external transfer equipment first lifts the transport unit 100 to disengage from the rotating lock device on the support bracket 322, and then the external transfer equipment carries the transport unit 100 horizontally (perpendicular to the axial direction of the track beam 220) to move the transport unit 100 out of the area defined by the two support brackets 322.

[0146] See also Figure 9 In some embodiments, when the transport unit 100 adopts the standard transport unit 110, a bottom door opening and closing touch device 325 can also be set on the support bracket 322 to act on the bottom door opening and closing component 113 of the standard transport unit 110, so that the bottom door opening and closing component 113 drives the bottom door component 112 to open or close the discharge port 115, thereby facilitating online unloading.

[0147] In some embodiments, the integrated motion vehicle 300 and the track beam 220 adopt a "vehicle holding track" assembly structure, see Figure 8 The bogie assembly 310 includes a frame component 311, at least two U-shaped wheel frames 312, at least four wheel assemblies 313, and at least two sets of retainers 314. The bogie assembly 310 is located below and parallel to the track beam 220. The U-shaped wheel frames 312 are arranged on the frame component 311. The bottom portion of the closed box beam 221 is located in the U-shaped cavity of the U-shaped wheel frames 312, forming a "car-on-rail" running mechanism. This can be adapted to the closed box beam 221, effectively reducing the derailment rate of the bogie assembly 310 and improving the safety performance of the aerial rail transportation system 1000. At least four wheel assemblies 313 are respectively mounted on the at least two U-shaped wheel frames 312, so that the wheel assemblies 313 can move along the two tracks 222. At least two sets of retainers 314 are respectively connected between two adjacent U-shaped wheel frames 312 to improve the structural strength and rigidity of the entire bogie assembly 310.

[0148] See also Figure 7 and Figure 9In some embodiments, the transport vehicle 300 further includes at least two stabilizing legs 340. The at least two stabilizing legs 340 are relatively arranged on the bogie assembly 310 or the frame assembly 320, and the stabilizing legs 340 can be extended and retracted relative to the frame assembly 320 so that the stabilizing legs 340 abut between the bogie assembly 310 and the frame assembly 320. By providing the stabilizing legs 340 between the bogie assembly 310 and the frame assembly 320, online cargo loading and unloading can be performed without changing containers. During the cargo loading and unloading process, the stabilizing legs 340 are extended and abutted between the bogie assembly 310 and the frame assembly 320, thereby improving the posture stability of the frame assembly 320 and the carrier unit 100, enabling the aerial rail transport vehicle to achieve online cargo loading and unloading without dropping containers, simplifying the tedious process of changing containers for bulk cargo, and improving the efficiency of cargo loading and unloading.

[0149] See also Figure 7 and Figure 9 In some embodiments, the frame assembly 320 of the transport vehicle 300 further includes a dust cover 323, which is openably provided on the body 321 of the frame assembly 320. The opening method of the dust cover 323 is not limited to rotating, lifting, and sliding.
