[0002] In the existing air rail system, the walking mechanism of the air rail transport vehicle generally adopts a motor-driven rubber wheel. The rubber wheel has good damping effect due to its own elasticity, and the surface of the rubber wheel is relatively rough compared with the steel wheel, and has good grip ability, and can walk on the track beam with a certain slope.

[0003] The existing air rail system generally has a short stroke, and the line length is below 15 km. However, with the increase of logistics demand, it is required that the air rail system can have a greater driving distance (line length above 20 km), and the air rail transport vehicle has a faster running speed. However, the rubber wheel has poor heat dissipation, low service life, high maintenance cost, and low allowable driving speed, which leads to the air rail system not suitable for long-distance transportation.

[0092] In order to make the skilled in the art to which the present application belongs more clearly understand the present application, the following will be combined with the drawings in the embodiments of the present application, the technical solutions in the embodiments of the present application are described clearly and completely, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without making creative labor are within the scope of protection of the present application.

[0093] The first aspect of the present application provides an empty rail system, please refer to Figure 1 , shows the structure schematic diagram of the empty rail system in one or more embodiments of the present application. The empty rail system includes a rail system 200 and a container vehicle 300. The container vehicle 300 is connected to the carrying unit 100, which can adopt the hanging connection mode or the bottom supporting connection mode, and the present application does not make limitation. The rail system 200 is arranged between the first yard and the second yard, and the container vehicle 300 runs back and forth between the first yard and the second yard to transfer the carrying unit 100. The electric energy required for the operation of the container vehicle 300 is provided by the traction and power supply system, and the electric energy provided by the traction and power supply system is used to generate the traction force to drive the container vehicle 300 to run, and on the other hand, to supply power to the electric equipment on the container vehicle 300.

[0094] Please refer to Figure 1 , the overall arrangement structure schematic diagram of the rail system can be shown, in some embodiments, the rail system 200 is a closed loop structure, including the first transfer section 201 close to the cargo production area, the second transfer section 202 close to the railway station, and the empty car transport section 203 and the heavy car transport section 204 connected to the first transfer section 201 and the second transfer section 202, the carrying unit 100 connected by the container vehicle 300 running on the empty car transport section 203 is in empty state, and the carrying unit 100 connected by the container vehicle 300 running on the heavy car transport section 204 is in heavy state. Please refer to Figure 1In some embodiments, the empty container transport section 203 and the loaded container transport section 204 are arranged in parallel, so that the empty container transport section 203 and the loaded container transport section 204 have substantially the same length, facilitating the control of the running speed of the empty container transport vehicle 300 (referred to as "empty vehicle") connected to the empty container unit 100 (referred to as "empty container") and the loaded container transport vehicle 300 (referred to as "loaded vehicle") connected to the loaded container unit 100 (referred to as "loaded container") by the control system.

[0095] In some embodiments, the container transport system 1000 is applied in a scenario with a large altitude difference between the upstream and downstream, for example, the cargo production area is a mine with an altitude of 2500m, and the railway station has a relatively low altitude of 650m. The altitude of the first transfer section 201 is higher than that of the second transfer section 202. In order to save energy, in some embodiments, the container transport system 1000 adopts an operation control scheme of "empty vehicle uphill and loaded vehicle downhill", that is, the empty container transport vehicle 300 running on the empty container transport section 203 is uphill running, and the empty container unit 100 is transferred from the second transfer section 202 to the first transfer section 201; the loaded container transport vehicle 300 running on the loaded container transport section 204 is downhill running, and the loaded container unit 100 is transferred from the first transfer section 201 to the second transfer section 202. The downhill running of the loaded vehicle can save traction power by using its own weight.

[0096] Considering that the empty container transport vehicle 300 and / or the container unit 100 may fail during use, and routine inspection of the empty container transport vehicle 300 and / or the container unit 100 is also needed during normal use, please refer to Figure 1 In some embodiments, the track system 200 is provided with a storage track 205 for storing the empty container transport vehicle 300 and / or the container unit 100, a maintenance area 206 for maintaining the empty container transport vehicle 300 and / or the container unit 100, and a train inspection area 207 for inspecting the container unit 100 and / or the container unit 100. Since the loaded vehicle is loaded with goods, it is not convenient to stop for maintenance and inspection. In some embodiments, the storage track 205, the maintenance area 206 and the train inspection area 207 are arranged in the empty container transport section 203.

[0097] Please refer to Figure 1 The storage track 205, the maintenance area 206 and the train inspection area 207 are track sections arranged in parallel with the track of the empty container transport section 203, and a turnout is arranged at the entrance end, so that the empty container transport vehicle 300 can choose to continue driving along the empty container transport section 203 or drive into the storage track 205, the maintenance area 206 or the train inspection area 207 when driving to the turnout. The track branches such as the fault parking track 208, the storage track 205, the maintenance area 206 and the train inspection area 207 are connected with the track beam 220 through the turnout.

[0098] Please refer to Figure 17In some embodiments, the column inspection area 207 has 6 inspection parking spaces, which can accommodate 6 sports cars 300 for column inspection at the same time; the maintenance area 206 has 8 inspection parking spaces, which can accommodate 8 sports cars 300 for maintenance at the same time. The task range of the column inspection area 207 is: (a) to undertake the daily inspection of the running vehicles of the air track; (b) to undertake the temporary parking of the maintenance vehicles of the air track. The task range of the maintenance area 206 is: (a) to undertake the daily maintenance of the running vehicles of the air track; (b) to undertake the upgrading, testing and debugging of the air track vehicles.

[0099] In some embodiments, when the first yard is the goods yard of the goods production area, the goods need to be loaded in the carrying unit 100 first, accordingly, the storage line 205, the maintenance area 206 and the column inspection area 207 are close to the goods production area, that is, before the air track vehicle loading point, the container transportation system is arranged to manage, park, convert, test, maintain and repair the air track vehicles (sports cars 300). After the sports cars 300 are inspected / maintained, they are driven to the fast loading system 400 for loading, which ensures the stable operation of the heavy vehicles and reduces the failure rate of the heavy vehicles.

[0100] Please refer to Figure 1 In some embodiments, the empty vehicle transportation section 203 and the heavy vehicle transportation section 204 are each provided with more than one fault parking line 208. The sports car 300 with a fault or the sports car 300 connected to the carrying unit 100 with a fault can move to the fault parking line 208. The fault parking line 208 is a track section parallel to the track of the empty vehicle transportation section 203, and a turnout is arranged at the entrance end, so that the sports car 300 drives to the turnout and can choose to continue driving along the empty vehicle transportation section 203 or drive into the fault parking line 208.

[0101] The sports car 300 with a fault can drive into the fault parking line 208 by itself, or the sports car 300 with a fault can be towed by a normally running sports car 300, please refer to Figure 5 and Figure 6 In some embodiments, the sports car 300 is provided with a car coupler buffer device 360, and the structure of the car coupler buffer device 360 is the same as that of the car coupler buffer device of a railway vehicle. By arranging the fault parking line 208, when the container transportation system 1000 adopts beat production, the departure time, driving speed and stay time of each sports car 300 are pre-set by the program. If the sports car 300 and / or the carrying unit 100 in operation fails, the sports car 300 can be transferred to the fault parking line 208, so as to avoid affecting the operation of the subsequent vehicles.

[0102] The number of fault parking lines 208 depends on the length of the track system 200, and the distance between two adjacent fault parking lines 208 is approximately equal, for example, one fault parking line 208 is arranged every 3 km. In some embodiments, the locations of the fault parking lines 208 on the heavy vehicle transport section 204 correspond to the locations of the fault parking lines 208 on the empty vehicle transport section 203, that is, if a fault parking line 208 is arranged at a certain position on the heavy vehicle transport section 204, a fault parking line 208 is also arranged at a position corresponding to the certain position on the empty vehicle transport section 203. In some embodiments, the location of the fast installation system 400 is opposite to the storage line 205, and processes the fault vehicle, one of the fault parking lines 208 on the heavy vehicle transport section 204 is close to the fast installation system 400, and is opposite to the maintenance area 206 and / or the inspection area 207. Since the maintenance area 206 and the inspection area 207 can also park fault vehicles, they can be regarded as an alternative to the fault parking line 208.

[0103] The fault parking line 208, the storage line 205, the maintenance area 206 and the inspection area 207 are all track branches of the track system 200, which can adopt a closed track branch, that is, the vehicle drives into the track branch forwardly and drives out of the track branch forwardly, or can adopt an open track branch, that is, the vehicle drives into the track branch forwardly and drives out of the track branch reversely. The connection between the track branch and the main track of the track system 200 needs to use a turnout, and the closed track branch needs to use two sets of turnout structures, while the open track branch only needs to use one set of turnout structures, which is lower in cost. The specific branch structure of the fault parking line 208, the storage line 205, the maintenance area 206 and the inspection area 207 can be determined according to actual needs, which is not limited in the present application.

[0104] Please refer to Figure 2 , which shows a structural schematic diagram of a track system of an empty rail system. In some embodiments, the track system 200 includes a pier column 210 and a track beam 220 arranged on the pier column 210, and the track beam 220 is provided with a track 222. In some embodiments, the track 222 adopts a steel rail. The beam structure of the track beam 220 can adopt an I-shaped closed beam or an open beam, and the specific structure is not limited in the present application.

[0105] Please refer to Figure 2 and Figure 3 In some embodiments, the pier column 210 includes a corbel assembly 211 and a support 212 arranged on the corbel assembly 211, and the corbel assembly 211 is provided with two corbel assemblies 211 which are arranged at intervals along the width direction of the track beam 220. The track beam 220 includes a closed box beam 221, two tracks 222 arranged outside the closed box beam 221 and located on both sides, and a supporting part 223 arranged on the top of the closed box beam 221, and the supporting part 223 is arranged on the support 212.

[0106] The track beam of the prior art hollow rail system is mostly an open beam. For the open beam, the running wheel pressure is a partial load, and the fatigue performance is poor, resulting in an increase in the annular reinforcing rib of the track beam and the stiffening rib at the bottom of the running surface, and an increase in the dead weight. In addition, the wear and corrosion of the running surface will cause the running plate to thin, and it cannot be repaired. In addition, the lower opening structure of the open beam results in small 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, which has higher strength, stiffness and stability compared to the existing open beam, and can adapt to harsh environments with large carrying capacity (rated load: 32t), large slope (maximum slope 80 ‰) and large temperature difference (environmental temperature -25.5℃~48℃).

[0107] In some embodiments, please refer to Figure 3 The corbel assembly 211 includes a support column 213 and a corbel 214, the support 212 is arranged on the corbel 214, the top end of the support column 213 is in an integral structure or fixedly connected with the pier column 210, and the bottom end of the support column 213 is detachably connected with the corbel 214; or, the top end of the support column 213 is detachably connected with the pier column 210, and the bottom end of the support column 213 is fixedly connected with the corbel 214.

[0108] In some embodiments, the support column 213 and the pier column 210 are both steel structures, and the support column 213 and the pier column 210 are in an integral structure, which has higher strength than a split welding structure. In some embodiments, the support column 213 and the pier column 210 are integrally poured with concrete, so that the support column 213 and the pier column 210 are fixedly connected; the integrally poured concrete support column 213 and pier column 210 have low cost and good economy.

[0109] Please refer to Figure 3 and Figure 4 In some embodiments, the bottom of the closed box beam 221 is provided with a reinforcing assembly 224, the bottom plate of the closed box beam 221 extends outward to form a track mounting plate, the track is arranged on the upper surface of the track mounting plate, and the reinforcing assembly 224 is arranged on the lower surface of the bottom plate.

[0110] Please refer to Figure 4In some embodiments, the reinforcing assembly 224 comprises longitudinal reinforcing parts 225 and transverse reinforcing parts 226, which are connected to each other and arranged at an angle to enclose a cavity structure 227 with an opening. The reinforcing assembly 224 improves the axial and width direction strength of the track mounting plate, improves the effect of the track beam 220 resisting torsion, and improves safety. Since the track beam 220 is provided with a track, it is necessary to maintain and repair the structure for fixing the track. The cavity structure 227 enclosed by the longitudinal reinforcing parts and the transverse reinforcing parts 226 not only has the ability to improve the transverse strength, longitudinal strength, and resistance to torsion of the track beam 220, but also forms a maintenance opening for facilitating the maintenance of the fixed structure of the track.

[0111] In some embodiments, please refer to Figure 2 and Figure 3 The support part 223 is provided with two, and the two support parts 223 are respectively arranged at the two ends of the axial direction of the closed box beam 221 to realize the connection of the track beam 220 and the pier 210. In some embodiments, the support part 223 is a corbel 214 connected to the two sides of the closed box beam 221 in the width direction. In some embodiments, the support part 223 is a cross beam, which is symmetrically arranged on the top of the closed box beam 221, and the width of the cross beam is greater than the width of the top plate of the closed box beam 221, so as to reduce the stress concentration at the connection part of the cross beam and the closed box beam 221.

[0112] In order to improve the climbing ability, in some embodiments, the sports car 300 is driven by a linear motor, the stator 230 of the linear motor is arranged at the bottom of the track beam 220, and the mover 350 of the linear motor is arranged on the sports car 300. The sports car 300 is provided with a wheel assembly 313, and the wheel assembly 313 moves along the track 222 to transfer the carrying unit 100.

[0113] The wheels in the wheel assembly 313 can adopt rubber wheels or steel wheels. In some embodiments, the wheels in the wheel assembly 313 adopt steel wheels, which have a long service life and low maintenance cost. Especially for high transport capacity demand application scenarios, the sports car 300 adopts a suspension transportation mode, which can also be free from the limitation of wheel-rail adhesion, and realizes the climbing of the sports car 300 on a large slope (the maximum slope is 80‰), so the steel wheel can better meet the market demand. Moreover, compared with the rubber wheel (the longest continuous running time of a single test is 30 minutes, and the rubber wheel needs to be cooled for 5 minutes, otherwise there will be a risk of rubber cracking, peeling or falling off), the steel wheel can adapt to the transportation requirements of large transport capacity (rated load: 32t), large temperature difference (environmental temperature-25.5℃-48℃) and long distance (single trip 66km). The running speed of the steel wheel can reach 50-60km / h, and the running speed of the rubber wheel is generally less than 40km / h.

[0114] Please refer to Figure 5 ,Figure 6 and Figure 7 In some embodiments, the vehicle 300 comprises a bogie assembly 310, a frame assembly 320, and a suspension assembly 330 connected between the bogie assembly 310 and the frame assembly 320 to allow relative sway between the bogie assembly 310 and the frame assembly 320, and to resist wind level 11. The bogie assembly 310 is used to mount the mover 350 of the linear motor (with a gap of about 10 mm from the stator 230), and 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 to move along the two tracks 222 of the track beam 220. The frame assembly 320 is used to connect with the carrying unit 100.

[0115] Referring to Figure 5 and Figure 6 In some embodiments, the bogie assembly 310 is provided with a brake device 380 for deceleration braking when descending. Referring to Figure 5 and Figure 6 In some embodiments, the bogie assembly 310 is provided with a power supply device 370, which uses a sliding contact to contact the power rail on the track beam 220, and the power rail is connected to the traction power supply system to supply power (non-traction power) to the electrical equipment on the vehicle 300.

[0116] Referring to Figure 6 In some embodiments, when the frame assembly 320 is connected to the top of the carrying unit 100, the carrying unit 100 is in a hanging fixed manner, for example, the carrying unit 100 is a container 120 with an open top, and the frame assembly 320 is provided with a turn lock assembly that cooperates with the top corner piece of the container 120 to lock the container 120. The locking manner of the turn lock assembly cooperating with the top corner piece of the container 120 facilitates the loading and unloading of the container 120, but there is a certain safety risk in long-distance transportation.

[0117] Referring to Figure 5 In some embodiments, when the frame assembly 320 is connected to the bottom of the carrying unit 100, the carrying unit 100 is in a bottom supporting fixed manner, and the frame assembly 320 has two supporting frames 322, each of which is provided with a turn lock device that cooperates with the corner piece at the bottom of the carrying unit 100. Since the carrying unit 100 is placed on the two supporting frames 322, it is equivalent to being wrapped by the two supporting frames 322. Compared with the hanging fixed manner, the bottom supporting fixed manner has higher safety and is more suitable for long-distance transportation and can withstand harsh environments with large amounts of wind and sand. In order to load and unload the carrying unit 100 in the bottom supporting fixed manner, external adapter equipment needs to be used to Figure 5As shown in the example of the container movement vehicle 300, when the carrying unit 100 is unloaded, the external transfer device first lifts the carrying unit 100 to disengage the transfer locking device on the support frame 322, and then the external transfer device carries the carrying unit 100 to move (perpendicular to the axial direction of the track beam 220) to move the carrying unit 100 out of the area defined by the two support frames 322.

[0118] Please refer to Figure 5 In some embodiments, when the carrying unit 100 is a standard carrying unit 110 with a bottom door assembly 112 and a bottom door opening and closing assembly 113, a bottom door opening and closing contact device 325 can also be provided on the support frame 322 to act on the bottom door opening and closing assembly 113 of the standard carrying unit 110, so that the bottom door opening and closing assembly 113 drives the bottom door assembly 112 to open or close the discharge port 115, facilitating online unloading.

[0119] In some embodiments, the container movement vehicle 300 and the track beam 220 adopt a "vehicle embracing rail" assembly structure, please refer to Figure 7 The bogie assembly 310 includes a frame assembly 311, at least two U-shaped wheel frames 312, at least four wheel assemblies 313, and at least two sets of retaining frames 314. The bogie assembly 310 is located below the track beam 220 and parallel to the track beam 220. The U-shaped wheel frame 312 is arranged on the frame assembly 311, and the bottom part of the closed box beam 221 is located in the U-shaped cavity of the U-shaped wheel frame 312, forming a "vehicle embracing rail" running mechanism, which can adapt to the closed box beam 221, effectively reduce the derailment rate of the bogie assembly 310, and improve the safety performance of the container transport system 1000. The at least four wheel assemblies 313 are respectively installed on the at least two U-shaped wheel frames 312, so that the wheel assemblies 313 move along two tracks 222 respectively. The at least two sets of retaining frames 314 are respectively connected between the adjacent two U-shaped wheel frames 312, so as to improve the structural strength and rigidity of the entire bogie assembly 310.

[0120] Please refer to Figure 5 and Figure 6In 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.

[0121] See also Figure 5 and Figure 6 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 fine adjustment mechanism 550 is arranged on the lower platform 530 and is in force transmission connection with the upper platform 540. The fine adjustment mechanism 550 can fine adjust the position of the upper platform 540. The fine adjustment mechanism 550 can be a linear extension mechanism such as a telescopic cylinder, a ball screw driven by a motor, and the specific structure is not limited in the present application. In some embodiments, the fine adjustment mechanism 550 can fine adjust the lateral (perpendicular to the track beam 220) position and the longitudinal (parallel to the track beam 220) position of the upper platform 540. Therefore, the fine adjustment mechanism 550 is provided with at least two groups. The extension direction of at least one group of the fine adjustment mechanism 550 is lateral, and the extension direction of at least one group of the fine adjustment mechanism 550 is longitudinal. The upper platform 540 is used to carry the carrying unit 100. In some embodiments, a plurality of limiting structures 560 are arranged on the upper platform 540 to limit the carrying unit 100 placed thereon.

[0140] The fixed reconfiguring system 500 can be reconfigured with the collection vehicle 300 to meet the continuous transfer requirements of various types of standard containers or bulk cargo loading units. Please refer to Figure 14 When the fixed reconfiguring system 500 reconfigures the container, the whole machine is placed on the ground, and the longitudinal direction is 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 reconfiguring system 500, as shown in Figure 14 (a). The fixed reconfiguring system 500 fine adjusts the position of the upper platform 540 through the fine adjustment mechanism 550, so that the container 120 is centered with the lock of the collection vehicle 300, as shown in Figure 14 (b).

The box body 111 is an open structure from top to bottom. The top of the box body 111 is open to meet the needs of cargo loading. The bottom of the box body 111 is provided with a plurality of funnel ridges 114 at intervals. The area of the bottom surface of the box body 111 not covered by the funnel ridges 114 constitutes a discharge port 115. When unloading, the cargo falls from the discharge port 115. The bottom door opening and closing assemblies 113 are installed at the bottom of the box body 111 and below the funnel ridges 114. The bottom door opening and closing assemblies 113 are shielded by the funnel ridges 114 to avoid bulk cargo falling on the bottom door opening and closing assemblies 113. The bottom door assemblies 112 are installed at the bottom of the box body 111 and correspond to the position of the discharge port 115. The bottom door assemblies 112 are driven by the bottom door opening and closing assemblies 113 to open or close the discharge port 115. The specific structure of the bottom door assemblies 112 and the bottom door opening and closing assemblies 113 and the opening and closing mode of the bottom door opening and closing assemblies 113 can refer to the existing technology of the funnel container or the railway funnel car, and the specific content is not expanded here.

[0145] Referring to Figure 12 In some embodiments, the transport unit 100 further comprises a cubic frame 116. The box body 111 is installed at the upper part of the cubic frame 116. The bottom door assemblies 112 and the bottom door opening and closing assemblies 113 are located inside the cubic frame 116, so that the lower area of the entire cubic frame 116 is empty. The bottom door assemblies 112 and the bottom door opening and closing assemblies 113 are provided with a moving space, and are ensured to have a certain interval with the outside world to protect the bottom door assemblies 112 and the bottom door opening and closing assemblies 113 from being damaged or accidentally opened by external objects.

[0146] The cuboid frame 116 is connected to the motorized vehicle 300. In some embodiments, the carrying unit 100 is suspended below the motorized vehicle 300, and an angle piece 117 is arranged on the upper portion of the cuboid frame 116. The angle piece 117 of the cuboid frame 116 cooperates with a lifting device of the motorized vehicle 300. The specific structure can refer to the lifting structure of a container. In some embodiments, the carrying unit 100 is fixed by a bottom support. A locking piece (e.g., the angle piece 117 or a support plate) is arranged on the lower portion of the cuboid frame 116. The body of the motorized vehicle 300 is hooked to the bottom of the cuboid frame 116 to support the entire carrying unit 100.

[0147] Referring to Figure 10 and Figure 11 When the transfer device 700 is used to transfer goods and the carrying unit 100, on the goods production area side, the transfer device 700 includes the goods transportation equipment 800 and the quick loading system 400. The goods transportation equipment 800 includes a plurality of product bins and a belt conveyor for transporting goods. Taking coal as an example, the coal output by a coal preparation plant is transported to the quick loading system 400 by the goods transportation equipment 800. The quick loading system 400 loads the coal into the carrying unit 100. On the railway station side, the transfer device 700 can be used for full container unloading. Therefore, the transfer device 700 includes the fixed transshipment system 500 described above. If the transfer device 700 is used for bulk cargo unloading, the transfer device 700 includes the goods transportation equipment 800 and the loading system which are sequentially docked. Since the goods transportation equipment 800 and the quick loading system 400 are docked with heavy vehicles, the goods transportation equipment 800 and the quick loading system 400 are arranged in the heavy vehicle transportation section 204. The motorized vehicle 300 moves the container to above the product bin, and the carrying unit 100 directly unloads the bulk cargo into the product bin.

[0148] In some embodiments, if the transfer device 700 is used for bulk cargo unloading, the transfer device 700 includes the unloading bin, the goods transportation equipment 800 and the loading system which are sequentially docked. Since the unloading bin and the quick loading system 400 are docked with heavy vehicles, the unloading bin and the quick loading system 400 are arranged in the heavy vehicle transportation section 204. In some embodiments, the unloading bin is a warehouse established on the ground. The motorized vehicle 300 moves the container to above the unloading bin, and the bulk cargo is unloaded into the unloading bin through a buffer hopper. In some embodiments, the unloading bin is a coal receiving pit established on the ground or excavated on the ground. The motorized vehicle 300 moves the container to above the coal receiving pit, and the carrying unit 100 directly unloads the bulk cargo into the coal receiving pit.

[0149] The bulk cargo in the unloading bin is transferred to a loading system via cargo transport equipment 800. The loading system is located at a 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, the loading system 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.

[0150] In some embodiments, the container transportation system 1000 further includes a mobile loading system for docking the quick loading system 400 and the container transport vehicle 300. Figure 15 , shows a structural schematic diagram of the mobile changing system 600.

[0160] The empty and heavy vehicles are provided with traction power by the traction and power supply system, and the traction and power supply system is electrically connected with the stator of the linear motor. Please refer to Figure 18In some embodiments, the traction and power supply system comprises a bidirectional traction converter system, a downhill section traction system and an uphill section traction system. The bidirectional traction converter system is connected to an AC high-voltage bus and a DC high-voltage bus. The AC high-voltage bus is used to connect a traction substation. AC high-voltage power (for example, AC 35 kV) on the AC high-voltage bus is converted into DC high-voltage power (for example, DC 1500 V) by the bidirectional traction converter system. The downhill section traction system and the uphill section traction system both take power from the DC high-voltage bus. The downhill section traction system is used to provide power for heavy vehicles, and the uphill section traction system is used to provide power for empty vehicles.

[0161] When the heavy vehicle is going downhill, the gravitational potential energy of the vehicle is converted into kinetic energy of the vehicle. When the vehicle is maintaining a uniform speed or braking, the traction system needs to work in an electric braking mode to provide a force to stop the vehicle from accelerating or running. At this time, the downhill section traction system is in a power generation state, and can feed back electric energy to the DC high-voltage bus to increase the voltage of the DC high-voltage bus. The electric energy can be provided to the empty vehicle running in the reverse direction through the DC high-voltage bus. When the voltage of the DC high-voltage bus increases to the upper limit of the DC bus voltage, the bidirectional traction converter system works to feed back the excess electric energy to the AC high-voltage bus side through rectification and inversion. The electric energy can be provided to other traction substations through the AC high-voltage bus ring network, as shown in Figure 18 .

[0162] In some embodiments, the control system comprises an operation control system and an information system. Please refer to Figure 19 . The operation control system comprises a central device for data interaction with the information system, a vehicle-mounted device arranged on the vehicle 300, and a trackside device arranged beside the track system 200. The vehicle-mounted device comprises a speed sensor for detecting the running speed of the corresponding vehicle 300, an electronic tag for recording the identity information of the corresponding vehicle 300, and a vehicle-mounted loop antenna for data interaction with the central device. The trackside device comprises a loop communication unit, which is in communication connection with the central device and the vehicle-mounted loop antenna, and is used to realize data interaction between the vehicle-mounted device and the central device.

[0163] The information system mainly comprises an air rail transport management platform, an intelligent operation and maintenance management system, a comprehensive monitoring system and a basic support platform. The system framework is as shown in Figure 20The air-rail transportation management platform mainly integrates mine production management system, fast loading system 400, transportation control system, and station warehouse management system, etc. Through the organic combination and collaborative work of each system module, the safety and efficiency of air-rail transportation are realized, which is the core of the efficient operation of the entire air-rail. The transportation management system mainly includes transportation plan management, transportation order management, motor vehicle transportation state management, transportation exception management, data statistical analysis and other function modules. The intelligent operation and maintenance management system fully utilizes information technology and intelligent technology, and innovatively realizes active operation and maintenance of equipment, health management of equipment, information interaction with the rail system 200, the motor vehicle 300, the power supply system equipment, the coal fast loading equipment, the coal loading container, the information room, etc. The comprehensive monitoring system realizes real-time collection and centralized monitoring of data of air-rail related equipment and environment for the purpose of efficient transportation and safety protection, and assists in completing the coordination and linkage function between subsystems.

[0164] The basic support platform includes a machine room data center, a virtualization platform, and a network communication system. The machine room data center provides a support platform for the overall deployment of the air-rail information system, ensuring stable and efficient operation of the air-rail system. Important information technology equipment such as servers and core network devices are installed in the machine room, and auxiliary facilities such as power supply equipment, UPS equipment, air conditioning equipment, security equipment, fire fighting equipment, power and environmental monitoring equipment are configured. Meet the requirements of information technology equipment and operation and maintenance personnel for temperature, humidity, cleanliness, electromagnetic field strength, noise interference, electrical safety, power safety, waterproof, anti-seismic, lightning protection and grounding, etc. Provide a stable and reliable operating environment for information technology equipment, reduce equipment failure rate, and prolong equipment service life. The virtualization platform uses self-controllable virtualization technology to build a multi-node server cluster and build a private cloud architecture platform, providing a high-availability, high-efficiency, easy-to-maintain, and scalable operating environment for the intelligent air-rail information platform. Deploy data backup systems to achieve unified data backup management of the intelligent air-rail information platform. The network communication system uses optical fiber communication network, which is the main medium for data transmission of the intelligent air-rail information platform. A three-layer network system architecture is adopted to build a stable and efficient network communication system to meet the data exchange needs between subsystems of the intelligent air-rail information platform.
