Description

Technical Field

[0001] This utility model relates to the technical field of freight vehicles for aerial rail transport, specifically to a linear motor driven aerial rail coal transport vehicle suitable for box girder, an aerial rail transport system, and a coal loading and unloading 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 with large altitude differences between coal mines and coal transport railway stations, steep track gradients, and strong winds, the braking performance of traditional railway vehicle traction mechanisms is insufficient to meet operational requirements. Aerial rail transport driven by linear motors can significantly improve the vehicle's climbing performance, is not limited by terrain, and is a suitable solution for coal transportation under conditions of steep gradients and large elevation differences.

[0004] Existing suspended monorail systems use solid rubber wheels or pneumatic tires for their running gear, which suffers from significant rubber wheel wear, short service life, and high maintenance costs throughout the vehicle's lifespan. Market demand for freight monorails is widespread, requiring high-volume, high-frequency, long-distance transport on steep inclines. Rubber-wheeled vehicles struggle to meet reliability requirements for long-distance, high-volume transport, and wheel maintenance is costly and uneconomical. Therefore, there is a need to design a linear motor-driven monorail coal transport vehicle with steel wheels and rails, suitable for box girder construction. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0062] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0063] like Figures 1 to 3 As shown, a linear motor-driven overhead coal transport vehicle suitable for box girder rails includes a bogie 1 and a car body 2. The bogie 1 and the car body 2 are connected by a central suspension device 3. The car body 2 runs on an overhead box girder rail 4 via the bogie 1. An electrical system 8 is also installed on the car body 2, and end-connection devices, which are couplers or drawbars, are installed at both ends of the car body 2.

[0064] like Figures 4-6 As shown, the bogie is the running mechanism of the vehicle on the elevated track. The bogie 1 includes a frame 101, two sets of wheelsets 102, a linear motor 103, and a braking device 104 for braking the wheelsets 102. The two sets of wheelsets 102 are arranged opposite each other along the length of the frame 101. The linear motor 103 is arranged on the frame 101 and extends along the length of the frame 101. The linear motor 103 is located above the two sets of wheelsets 102. The bottom of the elevated box girder track 4 is provided with a stator, and the frame 101 is provided with a mover that is coupled to the stator. An air gap 19 is reserved between the mover and the stator. Through the mutual coupling between the mover and the stator coil, the vehicle body 2 is driven to travel along the elevated box girder track. The wheelset assembly 102 is connected to the frame 101 via a primary suspension device 105. A motor spring 106 is installed at the bottom of the linear motor 103, which is mounted on the frame 101 via the spring. Motor brackets 107 are installed on both sides of the linear motor 103 for support. Positioning wheelsets 108 are also installed at both ends of the linear motor 103 along its length. In this embodiment, a mover is provided at the top of the bogie frame. The mover interacts with the stator coil at the bottom of the track beam, enabling the vehicle to travel along the track. An air gap of approximately 10mm is reserved between the mover at the top of the bogie and the stator at the bottom of the box-type track beam; the smaller the gap, the greater the vehicle's traction. An air gap adjustment device is provided on the frame to adjust the mover height. The height of the mover bracket is adjusted by tightening the upper and lower nuts, allowing for vertical adjustment, such as when wheel wear is high.

[0065] like Figures 7-8As shown, to meet the requirements for vehicle use in windy environments, a central suspension device is installed between the car body and the bogie. The central suspension device 3 includes a center pin 301, several vertical rubber damping springs 302, and oblique spring dampers 303. The bogie 1 is connected to a bolster 5 via the center pin 301, and the car body 2 is mounted on the bolster 5 via several vertical rubber damping springs 302. The oblique spring dampers 303 are obliquely connected between the bogie 1 and the car body 2. The central suspension device provides vertical rubber damping springs, and the oblique spring dampers are located on both sides of the pin. This not only provides shock absorption when the vehicle rolls, but also ensures the horizontal stability of the vehicle after loading and unloading the boxes, which is beneficial for the matching of the vehicle with the ground transfer equipment. A lateral stop 6 is installed between the bolster 5 and the car body 2. The side of the bogie 1 frame 101 is connected to the car body 2 via a longitudinal traction rod 7. 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. The car body rests on the bolster's upper surface via four rubber springs, while lateral stops are installed between the bolster and the car body to suppress excessive lateral displacement between the bolster and the car body.

[0066] like Figures 1 to 3 , Figures 9-10 As shown, the vehicle body 2 includes a frame 201 and a funnel box 202. The funnel box 202 is installed in the lower middle part of the frame 201, and both ends of the funnel box 202 are supported by hook arm beams 203 at the bottom of the funnel box 202. A rotary locking device 204 is provided on the hook arm beams 203 for connecting and fixing the frame 201 and the funnel box 202. The rotary locking device 204 includes a rotary lock head 2041, a rotary lock handle 2042, and a rotary lock positioning device 2043. The rotary lock head 2041 is installed on the frame 201, and a funnel box corner piece 205 is provided on the funnel box 202. The rotary lock head 2041 extends into the funnel box corner piece 205. The rotary lock handle 2042 is hinged to the bottom of the rotary lock head 2041. The rotary lock positioning device 2043 is provided on the rotary lock handle 2042 for positioning the rotary lock handle 2042.

[0067] like Figures 11-13As 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. The two sets of bolster beams 2013 are located between the two sets of end beams 2012. The end beams, center beams, and bolster beams are all steel structures. A hook arm beam 203 is disposed below the two sets of bolster beams 2013. The bolster beams 2013 and the hook arm beams 203 are an integral structure. The hook arm beams are used to support the funnel box. An accessory 206 is disposed above the bolster beams 2013. The accessory provides mounting support for various electrical equipment. A safety shackle 207 is provided between the frame 201 of the car body 2 and the frame 101 of the bogie 1. The frame and the car body are equipped with a safety shackle to prevent the vehicle from falling due to pin breakage in extreme cases.

[0068] like Figures 14-16 As shown, the hopper box 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, a bottom door opening / closing mechanism 2025 for opening or closing the bottom door, a top cover 2026, and a top cover opening / closing mechanism 2027 for opening or closing the top cover. The end walls 2022 are located at both ends of the side walls 2021, and the side walls 2021 and end walls 2022 form a box frame. The hopper ridge 2023 is located at the lower part of the box frame. The bottom door 2024 and the bottom door opening / closing mechanism 2025 are located at the bottom of the box frame, and the top cover 2026 and the top cover opening / closing mechanism 2027 are located at the top of the box frame.

[0069] like Figures 17-18 As shown, the bottom of the funnel box 202 is provided with at least two bottom doors 2024. The bottom door opening and closing mechanism 2025 includes a main shaft assembly 20251, a connecting rod assembly 20252, and a door opening and closing arm 25253. The bottom doors 2024 are connected to the main shaft assembly 20251 through the connecting rod assembly 20252. The door opening and closing arm 25253 is located at the end of the main shaft assembly 20251. By contacting the touch table through the door opening and closing arm 25253, the main shaft assembly 20251 can drive the connecting rod assembly 20252 to rotate clockwise or counterclockwise, thereby opening or closing the bottom doors 2024.

[0070] like Figures 19-20 As shown, the top of the funnel box 202 is provided with at least 4 top covers 2026. The top cover opening and closing mechanism 2027 includes a cylinder 20271 for driving the top cover 2026 to translate. The top cover 2026 is opened or closed under the driving action of the cylinder 20271.

[0071] like Figures 23-24As shown, this utility model discloses an aerial rail transport system comprising several linear motor-driven aerial rail coal transport vehicles with box girders as described above. Three such vehicles form a group, and adjacent vehicles are connected by a traction rod 9. Couplers 10 are installed at both ends of the first and last vehicles in each group, and adjacent groups are connected by couplers 10. In this embodiment, the linear motor-driven aerial rail coal transport vehicles with box girders form a group of three, with vehicles in each group connected by traction rods and vehicles in each group connected by couplers. The vehicles are traction-driven by short-stator linear motors, and the interaction between the linear motor and the induction plate on the top of the rail beam enables acceleration, deceleration, and electric braking. The aerial rail transport system uses a three-vehicle formation, with small, closely spaced couplers and short-tail buffers at both ends of the vehicles. Figure 22 As shown; the vehicles are connected by a tow bar and a short tail buffer. The tow bar is a split structure, connected by bolts in the middle, which facilitates inspection and maintenance. Figure 21 As shown.

[0072] The braking system employs three types of braking: electric braking, tread braking, and top rail braking. The appropriate type can be selected based on different working conditions to ensure emergency braking and safe parking of the steel-wheeled vehicle on steep gradients in special circumstances, should the linear motor's electric braking fail. Normal vehicle operation relies on electric braking; when electric braking is insufficient, tread braking and top rail braking supplement or replace it.

[0073] The power supply equipment uses third-rail power to charge the onboard battery, which provides energy to the vehicle's drive system and electrical equipment. The electronic control equipment is the electrical control assembly for various devices on the vehicle, including the detection of vehicle speed, position, and status information, as well as signal transmission between the vehicle and the ground control center, and the execution of commands for the drive mechanism.

[0074] This utility model discloses a linear motor-driven overhead rail coal transport vehicle applicable to box-girder beams, primarily used for transporting coal, but also capable of transporting other bulk goods as needed. The vehicle employs a suspended transport method, suitable for box-girder track beam structures, and mainly consists of bogies, a car body, end-connecting devices, braking devices, and an electrical system. The vehicle uses a short-stator linear motor traction system, relying on the interaction force generated between the induction plate on the top of the overhead track beam and the linear motor on the bogie to achieve traction and electric braking. The vehicle uses steel wheels, allowing it to climb steep inclines without being limited by wheel-rail adhesion.

[0075] This utility model discloses a coal loading and unloading system for a linear motor-driven monorail coal transport vehicle applicable to box girder beams. The linear motor-driven monorail coal transport vehicle, applicable to box girder beams, operates in formation of three vehicles per train, loading and unloading at fixed locations. It includes a quick loading system 20, such as... Figures 25-27 As shown, the quick-loading system is installed at the coal loading point on both sides of the linear motor-driven air-rail coal transport car with a suitable box girder. The quick-loading system includes a buffer bin 11, a metering bin 12, a loading funnel 13, and a fixed scoop 14 connected sequentially from top to bottom. During coal loading, the coal is transported to the buffer bin 11 of the quick-loading system, and then loaded into the funnel box via the metering bin 12, loading funnel 13, and fixed scoop 14. The coal loading method is direct loading, meaning that the funnel box does not need to be removed from the vehicle during loading. The funnel box has an openable top cover, which can be opened automatically for coal loading. Three quick-loading systems are used, with each system loading one car. During loading, the air-rail coal transport car stops at the coal loading point, and the coal is transported to the buffer bin of the quick-loading system via a belt conveyor, and then loaded into the air-rail coal transport car via the metering bin, loading funnel, and fixed scoop. When loading coal, the vehicle remains stationary, and the quick loading system loads coal simultaneously from both sides of the vehicle. The fixed hopper below the loading funnel can swing back and forth to adjust the even distribution of coal in the funnel box.

[0076] like Figures 28-30 As shown, the coal unloading system 21 is located at the unloading point. The system includes an opening touch platform 15, a closing touch platform 16, a coal receiving hopper 17, and a clamping mechanism 18. The opening and closing touch platforms 15 and 16 are located on either side of the bottom door to trigger its opening or closing. The coal receiving hopper 17 is located below the bottom door to receive coal. The clamping mechanism 18 is located on both sides of the hopper box and contacts it to fix the vehicle body. The clamping mechanism includes guide wheels. In this embodiment, coal unloading is performed using a coal receiving pit. The overhead rail coal transport car stops at a fixed unloading point. An unloading system is provided at the unloading point, consisting of an opening touch mechanism, a closing touch mechanism, a coal receiving hopper, and a clamping mechanism. The opening touch mechanism includes an opening touch platform, and the closing touch mechanism includes a closing touch platform. The unloading system has three coal receiving hoppers, each corresponding to a specific overhead rail coal transport car. The guide wheels in the clamping mechanism contact the hopper box to fix the vehicle. After the monorail coal transport car delivers coal to the unloading point, it stops. The door opening contact mechanism 22, located on one side of the unloading pit, moves to the bottom of the car body and collides with the bottom door's opening and closing arm, opening the bottom door for unloading. After unloading is completed, the door closing contact platform on one side of the unloading pit moves and collides with the bottom door of the car body, closing the bottom door.

[0080] 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.

[0081] 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."

[0082] 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.

[0083] 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.
