Description

Technical Field

[0001] This utility model relates to the technical field of freight vehicles for aerial rail transport, specifically to an aerial rail pneumatic tire coal transport vehicle and an aerial rail transport system. Background Technology

[0002] Currently, coal transportation in my country mainly uses road, rail and waterway transportation. Coal from mining plants is mostly transported by container trucks, which transport the crushed fine coal from the coal mining area to the railway storage yard for long-distance transportation. Container truck transportation generally has problems such as environmental pollution and transportation safety hazards.

[0003] For operating environments characterized by significant altitude differences between coal mines and railway stations, steep gradients, and strong winds, the traction and braking performance of traditional railway vehicles is insufficient to meet operational requirements. This necessitates extensive truck transport, leading to problems such as congestion, pollution, inefficiency, and safety. In contrast, freight transport systems utilizing elevated rail transport have attracted widespread market attention and possess promising market prospects.

[0004] Existing suspended monorail freight systems typically use solid rubber wheels for their running gear. While solid rubber wheels offer advantages such as high load-bearing capacity, they also suffer from drawbacks including significant temperature rise over long distances and high maintenance costs throughout their lifespan. They are primarily suitable for short-distance, low-speed applications. For high-volume, high-frequency, and long-distance applications, the high maintenance costs of solid rubber wheels make them unacceptable to the market. Therefore, there is a need to design a coal transport vehicle with pneumatic tires. Utility Model Content

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] Firstly, the air-rail pneumatic tire coal transport vehicle of this utility model uses pneumatic tires, resulting in relatively less vibration between the vehicle and the air-rail beam. Compared with solid tires, pneumatic tires have better heat dissipation performance and allow for higher operating speeds. Compared with steel wheels, they have better vibration reduction performance, and the coupled vibration between the vehicle and the bridge is isolated by the tires, reducing the risk of resonance. The adhesion between the rubber and the steel plate is greater, resulting in stronger climbing ability and lower operating noise. The cost is lower than that of solid tires, and maintenance is more convenient than that of steel wheels and rails.

[0021] Secondly, the central suspension device of this utility model is equipped with vertical rubber shock-absorbing springs and oblique spring shock absorbers on both sides of the pin shaft. It can not only provide shock absorption when the vehicle rolls, but also the springs on the left and right sides can stabilize the vehicle's horizontal posture, ensuring the horizontal stability of the frame after loading and unloading the box, which is conducive to the matching of the box between the vehicle and the ground transfer equipment.

[0022] Thirdly, the bogie frame of this utility model is connected to the vehicle body via a longitudinal traction rod, and an oblique spring shock absorber is installed between the frame and the vehicle body to limit the lateral roll displacement of the vehicle body relative to the frame. The frame is connected to the bolster via a centrally arranged center pin, and the vehicle body rests on the upper plane of the bolster via four rubber springs. At the same time, a lateral stop is installed between the bolster and the vehicle body to suppress excessive lateral displacement between the bolster and the vehicle body.

[0023] Fourth, the coal loading method of the aerial track pneumatic tire coal transport vehicle of this utility model is box-changing loading. When loading coal, the box-changing equipment moves the funnel box out of the aerial track pneumatic tire coal transport vehicle for loading. The coal unloading method is receiving pit unloading. When unloading coal, the aerial track pneumatic tire coal transport vehicle corresponds to the receiving funnel set at the unloading point. The bottom door is opened or closed by the bottom door opening and closing mechanism to realize unloading. The loading and unloading method is simple and efficient. Attached Figure Description

The car body 2 is also equipped with an electrical system 7 and a braking system, and both ends of the car body 2 are provided with end connection devices, which are drawbars or couplers.

[0057] like Figures 4-6 As shown, the bogie is the running mechanism for a vehicle on an elevated track. The bogie 1 includes a frame 101, several sets of wheel assemblies 102, a motor drive unit 103, a basic braking device 104, and a gearbox 105. Each wheel assembly 102 includes two tires 1021, which are pneumatic tires and rotatably mounted on both sides of the frame 101 in the width direction.

The oblique spring dampers 303 are obliquely connected between the bogie 1 and the car body 2. The central suspension device, equipped with vertical rubber damping springs and oblique spring dampers on both sides of the pin, not only provides shock absorption during vehicle roll but also ensures horizontal stability of the vehicle, guaranteeing the horizontal stability of the frame after loading and unloading, which is beneficial for matching the vehicle with ground transfer equipment. The bogie frame is connected to the car body via longitudinal traction rods, and oblique spring shock absorbers are installed between the bogie frame and the car body to limit the lateral roll displacement of the car body relative to the frame. The frame is connected to the bolster via a centrally located center pin, and the car body rests on the bolster's upper surface via four rubber springs. At the same time, lateral stops are installed between the bolster and the car body to suppress excessive lateral displacement between the bolster and the car body.

[0059] like Figures 1 to 3 As shown in Figures 9 and 10, the vehicle body 2 includes a frame 201, a funnel box 202, and a top cover 203. The funnel box 202 is installed in the lower middle part of the frame 201. Both ends of the funnel box 202 are supported by the bottom of the funnel box 202 through the boom 204. The boom 204 is provided with a rotary lock device 205 for connecting the frame 201 and the funnel box 202.

[0060] like Figures 11-13 As shown, the frame 201 includes a center beam 2011, two sets of end beams 2012 disposed at the ends of the center beam 2011, and two sets of bolster beams 2013 disposed on the center beam 2011, with the two sets of bolster beams 2013 located between the two sets of end beams 2012. A boom 204 is disposed below the two sets of bolster beams 2013, with the two booms 204 arranged opposite to each other. The center beam 2011, end beams 2012, bolster beams 2013, and booms are all steel structures. An accessory 206 is disposed above the bolster beams 2013. The accessory mainly consists of supports designed to interface with the bogie and mounting brackets for supporting electrical components.

[0061] like Figures 14-16As shown, the hopper box 202 is a carrier for transporting coal. The hopper box 202 includes two parallel side walls 2021, an end wall 2022, a hopper ridge 2023, a bottom door 2024, and a bottom door opening and closing mechanism 2025 for opening or closing the bottom door. The end walls 2022 are located at both ends of the side walls 2021. The side walls 2021 and the end walls 2022 form a rectangular frame. The hopper ridge 2023 is located inside the rectangular frame. The bottom door 2024 and the bottom door opening and closing mechanism 2025 are located at the bottom of the rectangular frame.

[0062] like Figures 17-19 As shown, the bottom of the funnel box 202 is provided with at least four bottom doors 2024, which are arranged longitudinally. The bottom door opening and closing mechanism 2025 includes a drive shaft 20251, a connecting rod 20252, and a drive cylinder 20253. The four bottom doors 2024 are arranged in two groups on both sides of the drive shaft 20251. The two bottom doors 2024 in each group are connected to the drive shaft 20251 through the connecting rod 20252. The drive cylinder 20253 extends or retracts the cylinder piston to act on the drive shaft 20251, thereby driving the bottom door 2024 to open or close. The bottom door adopts the four-bar linkage over-dead point principle to achieve self-locking, and the bottom door is driven to open or close by the drive cylinder.

[0063] like Figures 20-22 As shown, the top cover 203 includes a top cover body 2031, on which a plurality of top cover drive cylinders 2032 are provided.

The top cover body 2031 is raised and lowered under the action of the top cover drive cylinders 2032 to open or close. The top cover and the funnel box are separate structures. Preferably, each vehicle has 4 sets of top covers. The top cover drive cylinders are installed and fixed on the bolster beam of the vehicle body. The top cover is raised and lowered by the top cover drive cylinders to open or close. Grooved guide grooves are provided on the top cover body and the vehicle body to avoid the horizontal impact force of the cylinders.

[0064] like Figures 25-26 As shown, an aerial rail transport system includes several of the aforementioned aerial rail pneumatic tire coal transport vehicles. Three vehicles form a group, and adjacent vehicles are connected by a tow bar 8. Figure 23 As shown; each group of aerial rail pneumatic tire coal transport cars is equipped with couplers 9 at both ends, located at the first and last ends. Adjacent groups of aerial rail pneumatic tire coal transport cars are connected by couplers 9. Preferably, the couplers can be electrically controlled automatic couplers, such as... Figure 24 As shown, the aerial rail-mounted pneumatic tire coal transport vehicle uses a permanent magnet synchronous motor for traction, enabling the vehicle to accelerate, decelerate, and brake electrically.

[0065] like Figures 27-29 As shown, the present invention relates to a method for loading and unloading coal using an aerial rail pneumatic tire coal transport vehicle. The aerial rail pneumatic tire coal transport vehicle is operated in a formation of 3 vehicles per train, with loading and unloading taking place at fixed locations.

[0066] like Figure 27 As shown, the coal loading method is container-changing loading, using a three-position, two-unit container-changing coal loading system 11. During loading, the container-changing equipment removes the funnel box from the overhead rail pneumatic tire coal transport vehicle for loading. The overhead rail pneumatic tire coal transport vehicle, carrying an empty container, enters the loading / unloading position and stops. The loaded container is placed on the lifting platform of the container-changing equipment. The lifting platform lifts the loaded container, contacting the empty container attached to the overhead rail pneumatic tire coal transport vehicle during the lifting process. It then continues to lift the empty container until it separates from the overhead rail pneumatic tire coal transport vehicle and reaches a height difference of approximately 150mm. The lateral movement platform of the container-changing equipment moves laterally simultaneously with the empty and loaded containers until the loaded container is approximately 150mm above the attachment point of the overhead rail pneumatic tire coal transport vehicle and stops. The empty container then reaches the loading point on the other side. The lifting platform of the container-changing equipment descends simultaneously with the empty and loaded containers. During the descent, the loaded container first contacts the overhead rail pneumatic tire coal transport vehicle and lands on the attachment point. The lifting platform continues to descend with the empty container to the initial position. At this point, the loaded container is coupled to the overhead rail pneumatic tire coal transport car and awaits the departure signal. The empty container arrives at the coal loading point on the other side and begins loading. The quick loading system begins loading coal, and after loading is complete, the next shift begins. The loading process for the next overhead rail pneumatic tire coal transport car is then carried out in reverse.

[0067] like Figures 28-29 As shown, the coal unloading method is coal receiving pit unloading. During unloading, the air-rail pneumatic tire coal transport car corresponds to the coal receiving hopper set at the unloading point. The bottom door is opened or closed by the bottom door opening and closing mechanism to achieve unloading. The air-rail pneumatic tire coal transport car stops at a fixed unloading point. At the unloading point, there is an unloading system 12, which consists of a coal receiving hopper 13 and a clamping mechanism. The clamping mechanism is used to clamp the hopper box at the unloading point. The unloading system has three coal receiving hoppers 13, each corresponding to one of the air-rail pneumatic tire coal transport cars above. The hopper box for loading coal is equipped with a self-unloading bottom door and an opening and closing mechanism. The bottom door is opened and closed by a cylinder to achieve unloading.

[0068] It should be noted that the above description of the technical solutions is exemplary, and this specification may be embodied in different forms and should not be construed as limiting it to the technical solutions set forth herein. Rather, providing these descriptions will ensure that the disclosure of this utility model is thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Furthermore, the technical solutions of this utility model are defined only by the scope of the claims.

[0069] The shapes, dimensions, ratios, angles, and figures disclosed in the description of various aspects of this specification and claims are merely examples, and therefore, this specification and claims are not limited to the details shown. In the following description, detailed descriptions of relevant known functions or configurations will be omitted where it would be determined that they unnecessarily obscure the focus of this specification and claims.

[0070] When using the terms “comprising,” “having,” and “including” as described in this specification, there may be another part or other part unless used, and the terms used are generally singular but may also be plural.

[0071] It should be noted that although various components may appear and be described in this specification using terms such as "first," "second," "top," "bottom," "one side," "the other side," "one end," "the other end," etc., these components and parts should not be limited by these terms. These terms are only used to distinguish one component and part from another. For example, without departing from the scope of this specification, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component; top and bottom components may, under certain circumstances, be interchanged or converted; and components at one end and the other end may have the same or different performance characteristics.

[0072] Furthermore, when describing components, although not explicitly described, it is understood that a certain margin of error is necessarily included. When describing positional relationships, for example, when the positional order is described as "on," "above," "below," and "next," unless words or terms such as "exactly" or "directly" are used, situations where they are not in contact or are in contact can also be included. If it is mentioned that the first element is "on" the second element, it does not mean that the first element must be above the second element in the drawing. The upper and lower parts of the component will change depending on the viewing angle and orientation. Therefore, in the drawings or in the actual construction, the situation where the first element is "on" the second element can include situations where the first element is "below" the second element and situations where the first element is "above" the second element. When describing temporal relationships, unless "exactly" or "directly" is used, situations where the steps are not consecutive can be included when describing "after," "following," "subsequently," and "before."

[0073] The features of various embodiments of this utility model can be combined or spliced ​​together in part or in whole, and can be implemented in various different configurations as will be fully understood by those skilled in the art. Embodiments of this utility model can be implemented independently of each other, or can be implemented together through interdependent relationships.

[0074] The above are merely specific embodiments of this utility model. It should be noted that any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Any other aspects not described in detail are prior art.
