Description

Technical Field

[0001] The utility model relates to the technical field of freight vehicles for aerial rail transportation, in particular to an aerial rail coal transport vehicle driven by a linear motor suitable for an I-beam, an aerial rail transportation system and a coal loading and unloading system. Background Art

[0002] At present, my country's coal transportation mainly includes road, rail and water transportation. Coal mining plants mostly use container trucks to transport coal, and the crushed fine coal is transported from the coal mining area to the railway yard for long-distance transportation. Container truck transportation generally has problems such as environmental pollution and transportation safety hazards.

[0003] In environments such as the large altitude difference between coal mines and coal transport railway stations, steep line gradients, and strong winds, the braking performance of traditional railway vehicles' traction mechanisms is insufficient. Aerial rail transport using linear motors significantly improves vehicle climbing performance, unrestricted by terrain, making it a suitable solution for transporting coal on routes with steep slopes and large drops.

[0004] The existing suspended monorail systems all use solid rubber wheels or pneumatic tires for their vehicle running systems. These wheels suffer from high wear, a short service life, and high lifecycle operation and maintenance costs. From a market perspective, freight monorails are widely used for large-volume, high-frequency, long-distance, and steep-slope applications. Rubber-wheeled vehicles have difficulty meeting reliability requirements for long-distance, high-volume transportation, and the wheel maintenance costs are high, making them uneconomical. Therefore, it is necessary to design a linear motor-driven monorail coal transport vehicle with steel wheels and steel rails suitable for I-beams. Utility Model Content

Therefore, they cannot be understood as limitations on the present invention.

[0062] like Figures 1 to 3 As shown, a linear motor-driven overhead rail coal transport vehicle suitable for I-beams includes a bogie 1 and a car body 2, connected by a central suspension device 3. The car body 2 runs on an overhead I-beam track 4 via the bogie 1. The car body 2 is also equipped with an electrical system 5, and both ends of the car body 2 are provided with car end connection devices, which are drawbars or couplers.

[0063] In order to meet the requirements of the vehicle's use in a strong wind environment, a central suspension device is set between the car body and the bogie. The central suspension device 3 includes a vertical rubber shock-absorbing spring 301 and an oblique spring shock absorber 302. The vertical rubber shock-absorbing spring 301 is vertically connected between the bogie 1 and the car body 2; the oblique spring shock absorber 302 is relatively obliquely connected between the bogie 1 and the car body 2. Figures 7-8 As shown in the figure, a vertical rubber shock-absorbing spring is installed on the central suspension device, and oblique spring shock absorbers are installed on both sides of the pin. This not only provides shock absorption when the vehicle rolls, but also the oblique spring shock absorbers on the left and right sides can achieve horizontal posture stability of the vehicle, ensuring the horizontal stability of the frame after loading and unloading boxes, which is conducive to the matching of boxes between the vehicle and the ground transfer equipment.

[0064] like Figures 4 to 6As shown, the bogie is the running mechanism of the vehicle on the aerial track. The bogie 1 includes a frame 101, two groups of wheel sets 102, a linear motor 103 and a braking device 104 for braking the wheel set 102. The frame 101 is a U-shaped structure with the opening facing upward.

An air gap of approximately 10 mm is reserved between the mover at the top of the bogie and the stator at the bottom of the I-beam track beam. The smaller the gap, the greater the traction of the vehicle. An air gap adjustment device that can adjust the height of the mover is provided on the frame. By loosening and adjusting the height of the screw by the upper and lower nuts, the mover bracket can be adjusted in the up and down directions, such as when the wheels are worn.

[0065] like Figures 1 to 3 、 Figures 9 and 10 As shown, the vehicle body 2 includes a vehicle frame 201 and a funnel box 202. The funnel box 202 is installed in the middle of the vehicle frame 201, and the two ends of the funnel box 202 are supported on the bottom of the funnel box 202 through a hook arm beam 203; the hook arm beam 203 is provided with a rotary lock device 204 for connecting and fixing the vehicle frame 201 and the funnel box 202; the rotary lock 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 vehicle frame 201, and the funnel box 202 is provided with a funnel box corner piece 205, 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, and the rotary lock positioning device 2043 is provided on the rotary lock handle 2042 for positioning the rotary lock handle 2042.

[0066] like Figures 11 to 13As shown, the vehicle frame 201 comprises a center beam 2011, two sets of end beams 2012 disposed at the ends of the center beam 2011, and two sets of bolsters 2013 mounted on the center beam 2011, with the two sets of bolsters 2013 located between the two sets of end beams 2012. Below the two sets of bolsters 2013 is a hook arm beam 203, which is an integrated structure. The hook arm beam supports the hopper box and is equipped with a rotating lock device to connect the vehicle frame to the hopper box. An accessory 206 is located above the bolster beam 2013. The end beams, center beam, and bolster beams are steel structures. The accessory supports the vehicle frame and also provides mounting brackets for various electrical equipment.

[0067] like Figures 14 to 16 As shown, the funnel box 202 includes two parallel side walls 2021, an end wall 2022, a funnel ridge 2023, a bottom door 2024, a bottom door opening and closing mechanism 2025 for opening or closing the bottom door, a top cover 2026, and a top cover opening and closing mechanism 2027 for opening or closing the top cover; the end walls 2022 are arranged at both ends of the side walls 2021, the side walls 2021 and the end walls 2022 form a box frame, the funnel ridge 2023 is arranged at the lower part of the box frame, the bottom door 2024 and the bottom door opening and closing mechanism 2025 are arranged at the bottom of the box frame, and the top cover 2026 and the top cover opening and closing mechanism 2027 are arranged at the top of the box frame.

[0068] like Figures 17 and 18 As shown, the hopper box is a carrier for transporting coal. At least two bottom doors 2024 are provided at the bottom of the hopper box 202. The bottom door opening and closing mechanism 2025 includes a main shaft assembly 20251, a connecting rod assembly 20252 and a switch door arm 25253. The bottom door 2024 is transmission-connected to the main shaft assembly 20251 via the connecting rod assembly 20252. The switch door arm 25253 is provided at the end of the main shaft assembly 20251. When the switch door arm 25253 contacts the touch platform, the main shaft assembly 20251 can drive the connecting rod assembly 20252 to rotate clockwise or counterclockwise, thereby opening or closing the bottom door 2024.

[0069] like Figures 19 and 20 As shown, at least two top covers 2026 are provided on the top of the funnel box 202, and the top cover opening and closing mechanism 2027 includes a cylinder 20271 and a connecting rod 20272, one end of the connecting rod 20272 is connected to the top cover 2026, and the other end of the connecting rod 20272 is connected to the cylinder 20271, and the top cover 2026 is opened or closed under the lifting action of the cylinder 20271.

[0070] like Figures 23 and 24As shown, an aerial rail transport system includes a number of the above-mentioned I-beam linear motor driven aerial rail coal transport vehicles, each of which is a group of three I-beam linear motor driven aerial rail coal transport vehicles, and two adjacent I-beam linear motor driven aerial rail coal transport vehicles are connected by a traction rod 6. Couplers 7 are provided at both ends of the first and last I-beam linear motor driven aerial rail coal transport vehicles in each group, and the adjacent I-beam linear motor driven aerial rail coal transport vehicles are connected by couplers 7. In this embodiment, the aerial rail coal transport vehicles are grouped into groups of three, and the vehicles in each group are connected by traction rods, and the vehicle groups are connected by couplers. The vehicles are towed by short-stator linear motors, and the interaction force between the linear motors and the induction plates on the top of the rail beams is used to realize the acceleration, deceleration, electric braking and other functions of the vehicles. A three-car formation is used, and small close-fitting couplers and short-tail buffers are used at both ends of each group, such as Figure 22 As shown; a tow bar and short tail buffer are used between vehicles. The tow bar is a split structure, connected by bolts in the middle, which is convenient for inspection and maintenance. Figure 21 shown.

[0071] The braking system can be selected based on different operating conditions, using electric braking, tread braking, and top rail braking. This ensures emergency braking and safe parking on steep slopes if the linear motor's electric brake fails in exceptional circumstances. The transport vehicle relies on electric braking for routine operation. When electric braking is insufficient, tread braking and top rail braking supplement or replace it.

[0072] The power supply equipment uses the third rail to charge the onboard battery, which in turn provides energy for the vehicle's drive system and electrical equipment. The electronic control equipment is the electrical control assembly for various devices on the vehicle. It detects the vehicle's speed, position, and status, transmits signals between the vehicle and the ground control center, and executes commands for the drive mechanism.

[0073] The present invention's aerial rail coal transport vehicle is primarily used for transporting coal, but can also handle other bulk cargo depending on transportation needs. The vehicle utilizes a suspended transport system suitable for I-beam track structures and primarily consists of a bogie, a vehicle body, vehicle-end connections, a braking system, and an electrical system. The vehicle utilizes a short-stator linear motor traction system, utilizing the interaction force generated by an induction plate at the top of the aerial I-beam track along the route and the linear motor on the bogie to achieve traction and electric braking. The vehicle utilizes steel wheels, which are unrestricted by wheel-rail adhesion and can climb steep slopes.

[0074] The utility model is suitable for the loading and unloading system of the I-beam linear motor driven empty rail coal transport vehicle, such as Figures 25-29As shown, the system includes a quick-loading system 17, which is installed on both sides of an I-beam linear motor-driven air-rail coal transport vehicle at the coal loading point. The quick-loading system includes a buffer bin 8, a metering bin 9, a coal-loading hopper 10, and a fixed dustpan 11, which are connected in sequence from top to bottom. During loading, coal is transported to the quick-loading system's buffer bin 8 and then loaded into the hopper box through the metering bin 9, the coal-loading hopper 10, and the fixed dustpan 11. In this embodiment, the I-beam linear motor-driven air-rail coal transport vehicles are operated in trains of three vehicles each, with loading and unloading taking place at fixed locations. The coal loading method is direct loading, meaning the hopper box does not need to be removed from the vehicle during loading. A removable cover is installed above the hopper box, which is automatically opened to allow loading. Three quick-loading systems are used, each for loading a vehicle. During loading, the railcar stops at the loading point. The coal is transported via a belt conveyor to the quick-loading system's buffer bin. From there, it passes through a metering bin, loading hopper, and fixed buckets, then is loaded into the railcar. While the vehicle remains stationary, the quick-loading system loads both sides of the vehicle simultaneously. The fixed bucket beneath the loading hopper swings back and forth to evenly distribute the coal within the hopper.

[0075] like Figures 28-30 As shown, the coal unloading system is installed at the unloading point. It includes a door opening touch station 12, a door closing touch station 13, a coal receiving hopper 14, and a clamping mechanism 15. The door opening touch station 12 and door closing touch station 13 are located on either side of the bottom door to trigger the opening or closing of the bottom door. The coal receiving hopper 14 is located below the bottom door to receive coal. The clamping mechanism 15 is located on both sides of the hopper box and contacts it to secure the vehicle. The clamping mechanism includes guide wheels. Unloading is performed using a receiving pit. The aerial rail coal transport vehicle stops at a fixed unloading point. The unloading system is installed at the unloading point. This system consists of a door opening touch station, a door closing touch station, a coal receiving hopper 14, and a clamping mechanism 15. The door opening touch station includes a door opening touch station, and the door closing touch station includes a door closing touch station. The unloading system is equipped with three coal receiving hoppers, each corresponding to a specific aerial rail coal transport vehicle above. The guide wheels in the clamping mechanism contact the hopper box to secure the vehicle. When the aerial rail coal transport vehicle arrives at the unloading point and stops, the door opening contact mechanism 18 located on the unloading pit side moves under the vehicle body and collides with the door opening and closing arm of the bottom door, causing the bottom door to open and unload. After unloading is completed, the door closing contact platform on the unloading pit side moves and collides with the bottom door of the vehicle body, causing the bottom door to close.

[0076] It should be noted that the above description of the technical solution is illustrative only. This specification may be embodied in various forms and should not be construed as limiting the technical solution set forth herein. Rather, these descriptions are provided to ensure that the disclosure of this utility model is thorough and complete and to fully convey the scope of this disclosure to those skilled in the art. Furthermore, the technical solution of this utility model is limited only by the scope of the claims.

[0077] The shapes, sizes, ratios, angles, and numbers disclosed for describing various aspects of the present specification and claims are merely examples, and therefore, the present specification and claims are not limited to the details shown. In the following description, when a detailed description of a related known function or configuration is determined to be unnecessary to obscure the key points of the present specification and claims, the detailed description will be omitted.

[0078] When “including,” “having,” and “comprising” are used in this specification, unless otherwise used, there may also be another part or other parts, and the terms used may generally be singular but may also represent plural forms.

[0079] It should be noted that although the terms "first," "second," "top," "bottom," "one side," "the other side," "one end," "the other end," etc. may appear and be used in this specification to describe various components, these components and parts should not be limited by these terms. These terms are only used to distinguish one component or part from another. For example, without departing from the scope of this specification, a first component can be referred to as a second component, and similarly, a second component can be referred to as a first component. In certain circumstances, the components at the top and bottom can also be interchanged or switched with each other; the components at one end and the other end can have the same or different properties.

[0080] In addition, when constructing components, even if there is no explicit description thereof, it is understood that a certain error range is necessarily included. When describing positional relationships, for example, when the position sequence is described as "on...", "above...", "below...", and "next", unless words or terms such as "just" or "directly" are used, situations where they are not in contact or in contact can also be included. If it is mentioned that a first element is located "on" a second element, it does not mean that the first element must be located above the second element in the figure.
