Technical Field

[0001] This application belongs to the field of rail transportation technology, and in particular relates to a bogie assembly, an aerial rail transport vehicle, and an aerial rail transport system. Background Technology

[0002] Suspended aerial rail systems, whether for passenger or freight transport, generally use open-beam track beams. However, open-beam track beams have poor vertical rigidity, resulting in higher track costs for longer lines. Compared to open-beam track beams, fully enclosed track beams, which consist of box girders and tracks positioned on opposite sides of the box girders, use less steel and are more economical. However, there are no aerial rail transport vehicles specifically designed for fully enclosed track beams.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0041] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0042] This application is described below with reference to the accompanying drawings and specific embodiments:

[0043] In this field, the development level of multimodal transport remains relatively low, with road transport dominating. Problems such as poor coordination and integration between road, rail, and waterway transport, and lagging application of advanced technologies are prominent. Containers are widely used in port, logistics, and coal freight, but in actual transport, they are often constrained by the distance of railway stations and the complex surrounding environment in some areas, necessitating extensive truck transshipment, leading to significant issues of congestion, pollution, efficiency, and safety. Freight systems utilizing air-rail transport have attracted widespread market attention and possess promising market prospects.

[0044] In related technologies, suspended aerial rail systems, whether for passenger or freight transport, generally use open-beam track beams. However, open-beam track beams have poor vertical rigidity, resulting in higher track costs for longer lines. Compared to open-beam track beams, fully enclosed track beams, which include box girders and tracks positioned on opposite sides of the box girders, use less steel and are more economical. However, there are no aerial rail transport vehicles suitable for fully enclosed track beams.

[0045] To address the aforementioned problems, this application provides an aerial rail transport vehicle bogie assembly 10, such as... Figures 1 to 18 As shown, in some embodiments, the bogie assembly 10 includes a frame assembly 11, at least two U-shaped wheel frames 12, at least four wheel assemblies 13, and at least two sets of retainers 14. The frame assembly 11 is located below the overhead track beam 01, and its extension direction is the same as that of the overhead track beam 01. At least two U-shaped wheel frames 12 are mounted on the frame assembly 11, each including two opposing support arms 12a and a connecting arm 12b connecting the support arms 12a. The two support arms 12a extend to opposite sides of the overhead track beam 01. At least four wheel assemblies 13 are respectively mounted on the support arms 12a, such that the at least four wheel assemblies 13 are respectively placed on tracks 03 located on opposite sides of the overhead track beam 01. At least two sets of retainers 14 are respectively connected between two adjacent U-shaped wheel frames 12.

[0046] In some embodiments, the bogie assembly 10 of the aerial rail transport vehicle, by setting at least two U-shaped wheel frames 12 on the frame assembly 11, allows the support arms 12a to extend to opposite sides of the aerial rail beam 01, forming a "car-wrapped rail" running mechanism. This can be adapted to the fully enclosed aerial rail 03 structure. Since the aerial rail beam 01 of the enclosed aerial rail 03 structure uses fewer steel beams, the manufacturing cost of the aerial rail 03 can be reduced, resulting in better economy. Moreover, it can effectively reduce the derailment of the bogie assembly 10 and improve the safety performance of the aerial rail 03 transportation.

[0047] In some embodiments, the bogie assembly 10 is the running mechanism of the aerial rail transport vehicle. Unlike bogies in related technologies, in some embodiments, the bogie assembly 10 uses a U-shaped wheel frame 12, so that the two opposing arms 12a of the U-shaped wheel frame 12 extend to opposite sides of the aerial rail beam 01, thereby placing the wheel assembly 13 on the tracks 03 on opposite sides of the aerial rail beam 01. The bogie assembly 10 is partially wrapped around the aerial rail beam 01 from below, and the wheel assembly 13 can be formed on the tracks 03 on opposite sides of the aerial rail beam 01. At the same time, since the bogie assembly 10 is partially wrapped around the aerial rail beam 01, it can effectively prevent the bogie assembly 10 from detaching from the aerial rail beam 01, reducing the risk of derailment of the aerial rail transport vehicle.

[0048] In some embodiments, optionally, such as Figure 3 and Figure 5 As shown, the cage 14 may include a top cage 14a and a side cage 14b, wherein the two ends of the top cage 14a can be respectively connected to the ends of the support arms 12a of two adjacent U-shaped wheel frames 12, i.e., located as shown in the figure. Figure 3 At the top position of the U-shaped wheel frame 12 of the bogie assembly 10 shown, the two ends of the side retainer 14b can be connected to the connecting arms 12b and / or the support arms 12a of the two adjacent U-shaped wheel frames 12, so that the side retainer 14b is located on the side of the entire bogie assembly 10. The top retainer 14a and the side retainer 14b can maintain the structural strength of the bogie assembly 10 as a whole to avoid deformation, thereby preventing the aerial rail transport vehicle from falling off the track 03 and causing a safety accident.

[0049] In some embodiments, such as Figure 3 and Figure 5 As shown, the optional cage 14 components can all be connected by means of pins 14c passing through pin holes. The pins 14c are equipped with rubber ball sleeves 14d to reduce the damage to the structure caused by vibration and impact during the high-speed operation of the aerial rail transport vehicle.

[0050] As an alternative implementation method, such as Figure 3 and Figure 4 As shown, the bogie assembly 10 also includes:

[0051] At least one safety wheel 15 is provided on the frame assembly 11 and abuts against the bottom of the overhead track beam 01.

[0052] In some embodiments, the four wheel assemblies 13 are respectively located on the track 03 on the overhead track beam 01, so that the bogie assembly 10 forms a parallel contact with the track 03 through the four wheel assemblies 13. At the same time, the bogie assembly 10 is provided with at least one safety wheel 15 on the frame assembly 11. The safety wheel 15 abuts against the bottom of the overhead track beam 01. That is, the wheel assembly 13 and the safety wheel 15 are respectively located on the upper and lower sides of the track 03. The wheel assemblies 13d and the safety wheel 15 are clamped on the upper and lower sides of the track 03. Even if the wheel assembly 13 uses railway flanged wheels 13d, when the safety wheel 15 and the wheel 13d are in cooperation, the bogie assembly 10 can be prevented from shifting or deflecting relative to the overhead track beam 01, thereby effectively preventing the bogie assembly 10 from derailing from the overhead track beam 01.

[0053] Furthermore, by setting safety wheels 15, the distance between the bogie assembly 10 and the bottom of the overhead track beam 01 can be reduced, preventing other components of the bogie assembly 10 from directly contacting the bottom of the overhead track beam 01, thus preventing wear on the bogie assembly 10 when the overhead track transport vehicle is moving.

[0054] As an alternative implementation method, such as Figure 3 As shown, there are multiple safety wheels 15, and the orthographic projection of the safety wheels 15 on the bottom of the air track beam 01 is located outside the orthographic projection area of ​​at least four wheels 13 on the bottom of the air track beam 01.

[0055] In some embodiments, multiple safety wheels 15 are located at the bottom of the overhead track beam 01. The bogie assembly 10 can form a parallel contact with the overhead track beam 01 through the multiple safety wheels 15. Simultaneously, the bogie assembly 10 forms a parallel contact with the track 03 through four wheel assemblies 13. That is, the four wheel assemblies 13 and the multiple safety wheels 15 are respectively sandwiched between the upper and lower sides of the track 03, forming a "sandwich" structure. This allows the bogie assembly 10 to be stably mounted on the overhead track beam 01, effectively preventing derailment. Furthermore, if the orthographic projection of the safety wheels 15 on the bottom of the overhead track beam 01 is located outside the orthographic projection area of ​​at least four wheel assemblies 13 on the bottom of the overhead track beam 01, the virtual contact surface formed by the multiple safety wheels 15 and the bottom of the overhead track beam 01 is larger than the virtual contact surface formed by the four wheel assemblies 13 and the overhead track beam 01. By increasing the area of ​​the virtual contact surface formed by the multiple safety wheels 15 and the bottom of the overhead track beam 01, the bogie assembly 10 can be effectively prevented from shifting or falling off relative to the overhead track beam 01. Meanwhile, the virtual contact surface formed by multiple safety wheels 15 and the bottom of the aerial track beam 01 is larger than the virtual contact surface between the four wheel components 13 and the aerial track beam 01. This can be achieved by simply increasing the size of the frame component 11. Compared to increasing the area of ​​the virtual contact surface between the four wheel components 13 and the aerial track beam 01, this is more convenient, less costly, and more economically efficient.

[0056] As an alternative implementation method, such as Figures 1 to 4 As shown, the aerial rail transport vehicle is driven by a linear motor. The bogie assembly 10 also includes a mover 16 and a mover mounting frame 17. The mover 16 is magnetically coupled to the stator 04 of the linear motor located on the aerial rail beam 01. The mover mounting frame 17 is located on one side of the frame assembly 11 near the bottom of the aerial rail beam 01. The mover 16 is located on the side of the mover mounting frame 17 near the bottom of the aerial rail beam 01.

[0057] In some embodiments, by providing a mover mounting bracket 17 on one side of the frame assembly 11 near the bottom of the aerial track beam 01, and mounting the mover 16 on the side of the mover mounting bracket 17 near the bottom of the aerial track beam 01, the mover 16 can be magnetically coupled to the stator 04 of the linear motor provided on the aerial track beam 01. Through the interaction between the mover 16 and the stator 04 coil at the bottom of the aerial track beam 01, the aerial track transport vehicle can be made to travel along the extension direction of the track 03.

[0058] In some embodiments, the mover 16 may be a permanent magnet or an induction plate, which may generally be a copper plate or an aluminum plate.

[0059] In some embodiments, the aerial rail transport vehicle is driven by a linear motor; optionally, a linear motor with a long stator 04 can be used. On the one hand, this overcomes the limitation of adhesion between the wheel assembly 13 and the track 03, thus solving the problem of insufficient climbing ability in traditional aerial rail transport vehicles; on the other hand, as... Figure 1 As shown, the electrical equipment that originally needed to be placed on the aerial rail transport vehicle has been moved to the ground, the on-board electrical equipment has been greatly simplified, the reliability of the aerial rail transport vehicle has been greatly improved, and maintenance has become more convenient.

[0060] In some embodiments, the aerial rail transport vehicle does not have a complete traction device. When the stator 04 coil of the section 03 where the aerial rail transport vehicle is located is energized, the aerial rail transport vehicle is driven forward by the magnetic attraction between the stator 04 and the mover 16. When entering the next section of the track 03, the stator 04 coil of the next section is energized, and the aerial rail transport vehicle continues to move forward. The aerial rail transport vehicle continuously moves by the alternating energization of the stator 04 coils of each section of the track 03. The acceleration, deceleration, and electric braking functions of the aerial rail transport vehicle are realized by controlling the current and direction of the stator 04 coil.

[0061] In other embodiments, the aerial rail transport vehicle may also employ a different drive device than the linear motor described above. Those skilled in the art can make adaptive adjustments based on the structure of the aerial rail transport vehicle and the type of drive device, which will not be elaborated further here.

[0062] As an alternative implementation method, such as Figure 3 , Figure 4 as well as Figure 6 As shown, the bogie assembly 10 also includes a clearance adjustment device 18, which is disposed on the frame assembly 11, and the mover mounting bracket 17 is disposed on the frame assembly 11 via the clearance adjustment device 18.

[0063] In some embodiments, the smaller the gap between the mover 16 on the mover mounting bracket 17 and the stator 04 at the bottom of the overhead track beam 01, the greater the traction force. Furthermore, the smaller gap between the mover mounting bracket 17 and the bottom of the track beam 03 not only prevents the overhead track vehicle from derailing, but also prevents it from tilting when encountering extreme crosswinds.

[0064] In some embodiments, the optional clearance adjustment device 18 may include a screw and an upper nut and a lower nut disposed at both ends of the screw. The mover mounting bracket 17 is connected to the frame assembly 11 via the screw, upper nut, and lower nut of the clearance adjustment device 18. The height of the screw can be adjusted by adjusting the tightness of the upper nut and the lower nut, thereby adjusting the height of the mover mounting bracket 17 relative to the frame assembly 11, i.e., adjusting the distance between the mover 16 and the stator 04. When the clearance between the mover 16 and the stator 04 is too large due to factors such as excessive wear of the wheel assembly 13, it can be adjusted by the clearance adjustment device 18 to ensure that the clearance between the mover 16 and the stator 04 meets the design requirements, for example, maintaining the clearance between the mover 16 and the stator 04 at 10 mm ± 3 mm.

[0065] As an alternative implementation method, such as Figures 1 to 4 As shown, the bogie assembly 10 also includes a first braking device 19 and / or a second braking device 111. The first braking device 19 is disposed on the wheel assembly 13; the second braking device 111 includes at least two brake mounting brackets 110 and a second braking assembly. The at least two brake mounting brackets 110 are respectively disposed on the U-shaped wheel frame 12 or the retainer 14 assembly corresponding to the rail 03, and the second braking assembly is disposed on the side of the brake mounting bracket 110 adjacent to the rail 03.

[0066] In this application, the first rotating device can be a disc brake device, and the second braking device 111 can be a magnetic track brake device. The first braking device 19 and the second braking device 111 can be provided separately or simultaneously in the bogie assembly 10.

[0067] The braking device is an emergency braking device for the aerial rail transport vehicle, and it is a completely independent braking system. Normal operation of the aerial rail transport vehicle can be achieved through electric braking. When electric braking fails, the basic braking device can be used to achieve an emergency stop of the aerial rail transport vehicle, and it can also be used for parking braking when the aerial rail transport vehicle is stopped for a long time. In some embodiments, the bogie assembly 10 of the aerial rail transport vehicle adopts a combination of wheel disc braking and magnetic rail braking, with wheel disc braking as the primary method and a passive structure; magnetic rail braking is secondary, which can obtain additional braking force in addition to wheel-rail adhesion.

[0068] like Figure 10 and Figure 11 As shown, when the aerial rail transport vehicle needs emergency braking, the electromagnet of the magnetic track braking device is energized, and the brake pads are attracted to the surface of track 03. The magnetic attraction provides positive pressure, and the friction between the brake pads and the surface of track 03 stops the aerial rail transport vehicle, reducing the braking distance. When the aerial rail transport vehicle experiences a prolonged power outage, braking on steep slopes can also be achieved using only the disc brakes.

[0069] In some embodiments, the magnetic track brake can optionally achieve the attraction and separation of the bottom brake shoe and the track surface 03 by electromagnetic energization and de-energization. An air gap of 8 mm to 10 mm can be reserved between the magnetic shoe and the track surface 03, with vertical support provided by spring force. When energized, the magnetic attraction overcomes the spring force, the brake shoe attracts the track surface 03, and the brake shoe rubs against the track surface, providing braking force for the aerial rail transport vehicle. When de-energized, the magnetic attraction disappears, and under the action of spring force, the brake shoe separates from the track surface 03, and the braking force disappears.

[0070] In some embodiments, such as Figure 10 and Figure 11 As shown, optionally, magnetic track braking achieves the attraction and separation of the bottom brake shoe from the track surface 03 by changing the direction of the permanent magnet. An air gap of 8 mm to 10 mm can be reserved between the magnetic shoe and the track surface 03. When the magnet is arranged laterally, there is no magnetic force between the bottom brake shoe and the track surface, and a gap is maintained between the brake shoe and the track surface under the action of the top spring. When the hydraulic drive is depressurized (e.g., in an emergency situation such as a power failure), the handle rotates 90° under the action of the tension spring. At this time, the magnet and the track surface 03 generate a magnetic attraction force to overcome the top spring force, causing friction between the brake shoe and the track surface, thus achieving emergency braking of the aerial rail transport vehicle. When the hydraulic push rod pushes the handle to rotate 90°, the attraction between the magnet and the track surface disappears, and the brake shoe disengages from the track surface under the action of the top spring, at which point the braking is released. Since the magnetic attraction force can be designed as needed and is not limited by adhesion to the track surface 03, braking can be achieved on tracks with large gradients.

[0071] As an alternative implementation method, such as Figure 1 and Figure 7 As shown, the wheel assembly 13 includes a support sleeve 13a, a bearing 13b, an axle 13c, and a wheel 13d. The support sleeve 13a is mounted on the support arm 12a of the U-shaped wheel frame 12, the bearing 13b is mounted in the support sleeve 13a, and the axle 13c is mounted in the support sleeve 13a via the bearing 13b. The wheel 13d is mounted at one end of the axle 13c and is a steel wheel.

[0072] In some embodiments, the wheel assembly 13 enables the wheel 13d to have an independent rotation structure, and the cantilever support structure of the wheel 13d is achieved through two bearings 13b on two support arms 12a spaced at a certain distance. The support sleeve 13a in contact with the bearing 13b is an internal pressure support sleeve 13a made of high-strength steel, which can avoid the defect of insufficient local strength caused by excessive bending moment when the wheel 13d is under load.

[0073] In some embodiments, optionally, a spacer 13f is provided on the outside of the axle 13c, and at the same time, a through cover 13e and an end cover 13g can be provided at both ends of the bearing 13b respectively, so as to isolate the internal space of the bearing 13b from the outside; optionally, a labyrinth structure can be adopted at both ends of the bearing 13b to prevent lubricating oil leakage.

[0074] In some embodiments, optionally, an axle end cap 13h may be provided at the end of the axle 13c away from the wheel 13d to enclose the axle 13c in the wheel assembly 13.

[0075] In this embodiment, optionally, the aforementioned first braking device 19 can be provided at the shaft end cover 13h.

[0076] In related technologies, the running system of aerial rail transport vehicles uses solid rubber wheels or pneumatic tires, which have good shock absorption and comfort performance. However, this type of running system experiences significant wear and tear, has a short service life, and high maintenance costs throughout its life cycle. From a market perspective, aerial rail transport vehicles used for freight transportation have application requirements of large capacity, high frequency, long distance, and steep slopes. The maintenance cost of using running systems with rubber wheels is too high, making them difficult for the market to accept.

[0077] In some embodiments, the wheel 13d in the wheel assembly 13 is made of steel wheel. The wheel 13d has a long service life and low maintenance cost. Especially for application scenarios with high transport capacity requirements, the aerial rail transport vehicle adopts a suspended transport method and is not limited by wheel-rail adhesion. It can also achieve steep slope climbing of the steel wheel aerial rail transport vehicle. Therefore, steel wheel can better meet market demand.

[0078] Based on the same inventive concept, this application also provides an aerial rail transport vehicle, such as... Figure 1 and Figure 12 As shown, the aerial rail transport vehicle includes the aforementioned aerial rail transport vehicle bogie assembly 10, frame assembly 20, and suspension assembly 30 connecting the bogie assembly 10 and frame assembly 20. The frame assembly 11 includes a suspension connecting seat 11a extending away from the bottom of the track 03 beam. The suspension assembly 30 includes a suspension bracket 31, a vertical vibration damping device 34, and at least two oblique vibration damping devices 35. The suspension bracket 31 is connected to the suspension connecting seat 11a via a ball joint 32 and a connecting pin. The vertical vibration damping device 34 is vertically connected between the suspension connecting seat 11a and the suspension bracket 31. The at least two oblique vibration damping devices 35 are obliquely connected between the suspension connecting seat 11a and the suspension bracket 31.

[0079] Since the aerial rail transport vehicle provided by the present invention includes the bogie assembly 10 of the above-mentioned technical solution, all the beneficial effects of the above-mentioned bogie assembly 10 of the aerial rail transport vehicle provided by the present invention will not be elaborated here.

[0080] In some embodiments, the aerial rail transport vehicle can be applied to the field of heavy-duty cargo transportation, such as the transportation of standard goods like containers 02. Different chassis components 20 and container types can also be replaced according to transportation needs. For example, a chassis component 20 with an openable dust cover 25 can be used to achieve online loading, unloading, and transportation of bulk cargo, such as coal and grain. Simultaneously, this aerial rail transport vehicle can, in conjunction with ground transfer equipment, enable rapid transfer of goods from the ground to the aerial rail 03.

[0081] Furthermore, such as Figure 12 and Figure 1 As shown, in some embodiments, the suspension assembly 30 and bogie assembly 10 of the aerial rail transport vehicle are connected by ball joints 32 and connecting pins, allowing the suspension assembly 30 to have a certain amount of space movement in both the vertical and horizontal directions relative to the bogie assembly 10. This facilitates the aerial rail transport vehicle's movement during travel, curves, and loading / unloading of containers 02. Simultaneously, a vertical vibration damping device 34 and oblique vibration damping devices 35 located on opposite sides of the pins are provided. These not only provide shock absorption during the aerial rail transport vehicle's roll but also ensure the horizontal stability of the vehicle, guaranteeing that the frame assembly 20 remains horizontally stable after loading and unloading containers, thus facilitating container matching between the aerial rail transport vehicle and ground transfer equipment.

[0082] In some embodiments, the vertical damping device 34 and the oblique damping device 35 may be rubber spring dampers 39. In other embodiments, the vertical damping device 34 and the oblique damping device 35 may also be other devices with damping and buffering functions, which will not be described in detail here.

[0083] In some embodiments, such as Figure 3 As shown, in order to further ensure the suspension safety of the frame assembly 20, a safety shackle 60 is provided between the frame component 11 of the bogie assembly 10 and the frame assembly 20 to prevent the frame assembly 20 from falling due to the breakage of the pin 14c in extreme cases.

[0084] As an alternative implementation method, such as Figures 12 to 15 As shown, the suspension assembly 30 also includes an annular buffer 36, on which a high buffer block 36a and a low buffer block 36b are provided. The high buffer block 36a and the low buffer block 36b are spaced apart and distributed in an annular pattern on the inner wall of the annular buffer 36. The annular buffer 36 is sleeved on the suspension bracket 31, and the high buffer block 36a abuts against the suspension bracket 31.

[0085] In some embodiments, when the aerial rail transport vehicle passes through a curved section, the ball joint 32 in the suspension assembly 30 allows for a relative rotation angle between the bogie assembly 10 and the frame assembly 20. An annular buffer 36 is fitted onto the suspension bracket 31. High-position buffer blocks 36a and low-position buffer blocks 36b are arranged in a ring on the inner wall of the annular buffer 36, with the high-position buffer blocks 36a located on either side of the low-position buffer blocks 36b. The high-position buffer blocks 36a can contact the suspension bracket 31. When the aerial rail transport vehicle is traveling and passing through curved sections, the high-position buffer blocks 36a can transmit the force acting in the direction of travel of the aerial rail transport vehicle. When the aerial rail transport vehicle is moving and passing through curves, the horizontal rotation angle of the gap between the suspension bracket 31 and the suspension connecting seat 11a can be released by the low-position buffer block 36b located in the middle of the annular buffer 36. In other words, the suspension assembly 30 as a whole and the bogie assembly 10 can have a certain horizontal rotation angle, so that the frame assembly 20 as a whole has a certain horizontal rotation angle relative to the bogie assembly 10. This allows the frame assembly 20 as a whole to deflect a certain angle relative to the aerial rail 03 when passing through curves, thereby eliminating the bending stress of the curves and allowing it to pass through curves smoothly.

[0086] As an alternative implementation method, such as Figure 12 and Figure 15 As shown, U-shaped rubber baffles 38 or rubber pads can be provided at the contact points of the bogie assembly 10, suspension assembly 30 and frame assembly 20 to protect each structure from collision damage when there is a small relative movement between the bogie assembly 10, suspension assembly 30 and frame assembly 20.

[0087] For example, a U-shaped rubber baffle 38 is provided on the side of the frame assembly 20 adjacent to the suspension bracket 31. The U-shaped rubber baffle 38 isolates the side of the frame assembly 20 adjacent to the suspension bracket 31 from the suspension bracket 31, thereby preventing the frame assembly 20 from colliding with the suspension bracket 31 due to slight movement relative to the suspension bracket 31.

[0088] In some embodiments of the aerial rail transport vehicle, such as Figure 1 and Figure 2 As shown, the aerial rail transport vehicle also includes electrical equipment 40 and sliding conductive components 50. The electrical equipment 40 may include an electrical control device, which serves as the electrical control assembly for various devices on the aerial rail transport vehicle. This device includes functions such as detecting the speed, position, and status information of the aerial rail transport vehicle, and can also realize signal transmission between the aerial rail transport vehicle and the ground control center, as well as the execution of commands for the drive mechanism.

[0089] In some embodiments of the aerial rail transport vehicle, such as Figure 1 and Figure 2 As shown, the electrical equipment 40 can be slidably connected to a separate power supply rail 05 via a sliding conductive component 50 to supply power, thereby charging the on-board battery. The on-board battery provides energy to the electrical equipment 40 on the aerial rail transport vehicle, such as the drive unit and electrical equipment. The electrical equipment 40 uses third-rail power supply, which can ensure the safe and reliable power supply of the aerial rail transport vehicle.

[0090] In some embodiments of the aerial rail transport vehicle, the frame assembly 20 serves as the supporting structure for the container 02. The frame assembly 20 may be equipped with two sets of container 02 locking devices 23. These devices enable the locking and unlocking of the container 02 when its bottom is lifted by the transfer equipment. The container 02 locking devices 23 can provide dual protection with both mechanical and electrical locking devices. The electrical locking device 23 can be driven by a motor and gearbox to automatically open and close the corner fitting holes on the container 02. This dual locking system allows for rapid transfer of the container 02 from ground to air transport and ensures reliable connection with the frame assembly 20.

[0091] In some embodiments of the aerial rail transport vehicle, such as Figure 1 As shown, the end of the frame assembly 20 extending along the track 03 is provided with a coupler buffer device 70. The coupler buffer device 70 can realize the grouping and transportation of aerial rail transport vehicles, and can also be used for aerial rail transport vehicle rescue in special circumstances.

[0092] In some embodiments of the aerial rail transport vehicle, the frame assembly 20 may include a steel structure frame, mounting supports for installing various electrical equipment on the steel structure frame, and mechanisms such as a rotary locking device 23, a dust cover 25, a coupler buffer device 70, a drive motor 24, and guide plates, all mounted on the steel structure frame. The steel structure frame may include two parallel side beams and crossbeams and end beams connecting the side beams. A dust cover 25 may be installed on the frame structure formed by the crossbeams and side beams. The dust cover 25 is mainly suitable for open containers 02 to prevent coal ash or other types of dust from scattering during the transport of the aerial rail transport vehicle. Optionally, the edges of the dust cover 25 may also be provided with sealing rubber to prevent rain and snow from entering.

[0093] As an alternative implementation method, such as Figure 1 and Figure 16 As shown, the bottom of the bogie assembly 10 is provided with a vertical stop 37 extending vertically toward the frame assembly 20, and the frame assembly 20 is provided with a stop block 21 corresponding to the vertical stop 37.

[0094] In some embodiments, such as Figures 16 to 18As shown, a vertical stop 37 extending vertically towards the frame assembly 20 is provided at the bottom of the bogie assembly 10, and a stop block 21 corresponding to the vertical stop 37 is provided on the frame assembly 20. This prevents collisions between the bogie assembly 10 and the frame assembly 20. For example, when the lifting mechanism slightly lifts the frame assembly 20, it prevents the frame assembly 20 from damaging the bogie assembly 10. In addition, the vertical stop 37 and the corresponding stop block 21 can act as a limit stop when the frame assembly 20 rolls and sways under extreme crosswinds, preventing the container 02 from swinging too much and colliding with the support column of the track 03 beam.

[0095] Based on the same inventive concept, this application also provides an aerial rail 03 transportation system, which includes the above-mentioned aerial rail transport vehicle and aerial rail 03. The aerial rail 03 includes an aerial rail beam 01 and rails 03 located on opposite sides of the aerial rail beam 01.

[0096] Since the aerial rail 03 transportation system provided by the present invention includes the aerial rail transport vehicle of the above-mentioned technical solution, the aerial rail 03 transportation system provided by the present invention has all the beneficial effects of the above-mentioned aerial rail transport vehicle, which will not be elaborated here.

[0097] As an alternative implementation method, such as Figure 1 and Figure 2 As shown, the bottom of the aerial track beam 01 is provided with a stator 04 of a linear motor, and the bogie assembly 10 is provided with a mover 16 magnetically coupled to the stator 04. The gap between the mover 16 and the stator 04 is 10 mm ± 3 mm.

[0098] In some embodiments, the smaller the gap between the mover 16 and the stator 04, the greater the traction force of the linear motor. In this embodiment, by keeping the gap between the mover 16 and the stator 04 at 10 mm ± 3 mm, it is possible to ensure sufficient traction force for transporting the aerial track 03, and also to avoid friction caused by an excessively small gap between the mover 16 and the stator.

[0099] In some embodiments, the aerial rail 03 transportation system, such as Figure 18 As shown, the box-changing process is as follows:

[0100] The air rail control center controls the current in the stator 04 coil at the bottom of the air rail beam 01 to stop the air rail transport vehicle at the loading and unloading station. Ground-based transfer equipment with lifting capabilities carries container 02 to the bottom of the air rail transport vehicle. Container 02 is lifted until its corner fitting hole enters the air rail transport vehicle's rotary locking device 23. Triggering the top pin signal of the rotary locking device 23 stops the lifting. After the rotary lock rotates 90°, it is below the lifting mechanism of the transfer equipment, thus completing the transfer of container 02 from the ground equipment to the air rail transport vehicle. The air rail control center energizes the stator 04 coil at the bottom of the air rail beam 01, enabling the air rail transport vehicle to move continuously between stator 04 sections until it reaches the next loading and unloading point, completing the unloading. The unloading process is the reverse of the loading process and will not be described further.
