[0049] The accompanying drawings have illustrated specific embodiments of the present invention, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0050] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of mobile platform-type automated loading systems and methods consistent with some aspects of this invention as detailed in the appended claims.

[0051] In the scenario of loading trucks, bulk materials are stored in the unloading hopper after production. Fixed unloading equipment such as gates or coal feeders are used under the unloading hopper. When the truck loaded with materials arrives at the unloading hopper, the unloading is manually controlled and the driver is directed to move the truck.

[0052] The current material feeding method is as follows: Figure 1 As shown, loading is mainly done manually.

[0053] Right now, Figure 1 A schematic diagram illustrating application scenarios of existing technologies for loading bulk materials onto trucks, such as... Figure 1 As shown, the application scenario includes: material warehouse 1, carriage 2, and gate 3.

[0054] In one possible implementation, the on-site commander directs the vehicle driver to place the vehicle's cargo compartment 2 below the gate 3 and open the gate to release material. When the commander judges that the loading is almost complete, he directs the driver to move the vehicle to the left and load the rear half of the cargo compartment, thereby completing the loading of the vehicle.

[0055] However, this method can lead to uneven distribution of materials inside the truck bed due to inexperienced command personnel or excessively long or short driving distances.

[0056] To address the aforementioned technical problems, the inventors' technical concept is as follows: During the continuous descent of materials, the moving carriage can cause uneven accumulation of the material pile along its length (e.g., higher at the front and lower at the back, or localized overflow). The key to solving this problem is not controlling the material discharge, but coordinating the timing of the carriage's movement. This involves establishing the core feedback principle of using the real-time height of the material pile as the control signal, replacing the crude control relying on experience or timers. Furthermore, the continuous movement is decomposed into a discrete cycle of detection-achieving-stepping, creatively introducing a preset step size into the system. This ensures that each step creates a uniformly high material pile segment within a new carriage section. To achieve this, a device for detecting the material pile volume and a moving platform supporting the loading carriage are needed, and a drive mechanism is required to operate this moving platform.

[0057] To make the above-mentioned objectives, features, and advantages of the embodiments of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model 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 utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0058] It should be noted that the terms "side", "top", "bottom", "left", "right" and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0059] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0060] Figure 2 This is a first structural schematic diagram of the mobile platform-type automated loading system provided in an embodiment of the present invention, as shown below. Figure 2 As shown, the mobile platform-type automatic loading system includes: a mobile platform 21, a drive unit 22, a volume detection device 23, and a truck scale 24;

[0061] The mobile platform 21 is spaced below the discharge port (i.e., near the gate 3) of the material silo 1; the truck scale 24 is installed on the mobile platform 21 to support the loading vehicle and measure the weight of the loading vehicle.

[0062] The volume detection device 23 is installed near the discharge port and is used to vertically scan the material pile in the loading car to detect the current material pile height. When the volume detection device 23 detects that the current material pile height value is equal to the target material pile height value, the driving device 22 drives the moving platform 21 to move according to the preset step distance.

[0063] In this implementation, the volume detection device 23 can be set at the discharge port of the material bin 1, and can vertically scan the material bin into the loading vehicle to obtain the current material pile height value; the drive device 22 is used to provide the driving force for the operation of the moving platform 21. When the current material pile height value is detected to be equal to the target material pile height value, the drive force is provided to the moving platform 21. When the moving platform 21 travels a preset step distance, the drive force is stopped to stop the moving platform 21.

[0064] Optionally, the preset step distance and target material pile height can be set based on the relevant attributes of the loading vehicle, such as the dimensions of the loading compartment and the weight of the material.

[0065] For example, the target stockpile height mainly depends on the loading weight and the bulk density of the material. This ensures that after loading the predetermined weight of material, the stockpile height neither exceeds the side panels of the truck bed, preventing spillage, nor overloading the truck bed.

[0066] That is, total weight / material density = required total volume; then, the average height is calculated by back-calculating the length and width of the carriage, and an appropriate safety margin is left to obtain the target stockpile height value.

[0067] For example, setting the preset step distance essentially involves dividing the total length of the carriage by an integer, that is, dividing the carriage into N virtual small hoppers along its length. The amount of material loaded (weight or volume) at each step is 1 / N of the total amount loaded.

[0068] That is, let the available effective length inside the carriage be L; let the total weight to be loaded be W; and let the preset step distance be L / N.

[0069] It should be understood that the above examples are for illustrative purposes only and are not limitations for actual implementation.

[0070] Optionally, the volume detection device 23 can be configured as a millimeter-wave radar, lidar, etc., and can be installed at the gate of the material silo 1 below, with a rigid connection to ensure accuracy.

[0071] Furthermore, no restrictions are placed on the dimensions of the aforementioned mobile platform 21 and truck scale 24, but the truck scale 24 should be able to support the loading vehicle, i.e., its length and width should be greater than the length and width of the corresponding wheels of the loading vehicle; the dimensions of the mobile platform 21 may be greater than the dimensions of the truck scale 24; the dimensions of the mobile platform 21 may not be greater than the dimensions of the truck scale 24, but the specific design must ensure stability and safety during the loading process of the loading vehicle.

[0072] This utility model provides a mobile platform-type automatic loading system, comprising: a truck scale, a mobile platform, a drive unit, and a volume detection device. The mobile platform is spaced below the material discharge port of the material silo. The truck scale is installed on the mobile platform to support the loading vehicle and measure its weight. The volume detection device is installed near the discharge port to vertically scan the material pile inside the loading vehicle to detect the current pile height. When the volume detection device detects that the current pile height equals the target pile height, the drive unit moves the mobile platform according to a preset step distance. This solution uses the volume detection device to perform real-time vertical scanning of the material pile inside the loading vehicle, accurately obtaining the current height data. When the pile height reaches the preset target value, the drive unit immediately triggers the platform body to move the loading vehicle step by step, effectively avoiding problems such as uneven material pile, overflow, or insufficient utilization of the vehicle space caused by traditional continuous loading. It significantly improves the consistency of loading capacity, the level of automation, and overall efficiency, while reducing material spillage and the need for manual intervention.

[0073] Based on the above embodiments, Figure 3 This is a top view schematic diagram of the second structure of the mobile platform-type automated loading system provided in an embodiment of the present invention. Figure 4 This is a front view schematic diagram of the second structure of the mobile platform-type automated loading system provided in an embodiment of the present invention.

[0074] Combination Figures 3-5 This paper provides a detailed description of the mobile platform-type automatic loading system involved in this utility model.

[0075] Optionally, the drive device 22 includes: a wire rope 221, a guide pulley 222, and a drive assembly 223;

[0076] The wire rope 221 is wound in a loop on the mobile platform 21 via the guide pulley 222, and is used to pull the mobile platform 21 to move; the drive assembly 223 is connected to the wire rope 221 and is used to pull the wire rope 221 to move.

[0077] In this implementation, the wire rope 221 is wound in a loop around the mobile platform 21 (specifically, the platform body 211 described below) via the guide pulley 222, and is used to pull the mobile platform 21 to move; the drive assembly 223 is connected to the wire rope 221 and is used to pull the wire rope 221 to move. The motor in the drive assembly 223 can rotate forward and backward, which can drive the mobile platform 21 to travel forward or backward.

[0078] The steel wire rope 231 can be a high-strength steel wire rope (such as a 6×19 structure) connecting the platform body 211 at both ends to ensure load-bearing capacity; the drive assembly 223 can be driven by a variable frequency three-phase asynchronous motor or a servo motor, and the reducer can be a planetary gear reducer or a worm gear reducer, so that the moving speed of the platform body 211 is adjustable in the range of 0.1m / s-0.5m / s; the drive assembly 223 includes a winch, which uses a drum to wind, store, and release the steel wire rope 231, thereby performing traction, lifting, or dragging of heavy objects; the guide pulley 222 can also be... Figure 3-5 As shown in the diagram, the limiting unit 27 described below and the position next to the limiting unit 27 are provided.

[0079] In addition, the drive unit 22 can also have the following two designs:

[0080] Type 1, Hydraulic drive: The platform body 211 is moved by using a hydraulic cylinder; its components include: hydraulic cylinder, hydraulic pump station, and hydraulic valve group.

[0081] Among them, the hydraulic cylinder can be a long-stroke hydraulic cylinder, and the thrust needs to meet the load requirements; the hydraulic pump station can be a high-pressure hydraulic pump, which provides a stable hydraulic oil flow and pressure; the hydraulic valve group can control the extension and retraction speed and direction of the hydraulic cylinder.

[0082] The second type is rack and pinion drive: the platform body 211 is moved by using a rack and pinion transmission. The gear meshes with the rack and pinion, and the motor drives the gear to rotate, thus moving the platform. Its components are: rack, gear, and drive motor.

[0083] The rack can be a high-strength rack, fixed on the track 212 below; the gear can be a large-module gear, meshing with the rack and bearing high load; the drive motor can be a high-torque low-speed motor, driving the gear directly or through a reducer.

[0084] Optionally, the mobile platform 21 includes: a platform body 211 and a track 212;

[0085] Track 212 is located below the platform body 211 and is used to guide the running direction of the platform body 211.

[0086] In this implementation, the platform body 211 can move along the laying direction of the track 212, which serves as the running direction of the platform body 211; the track 212 is made of high-strength steel rails and is fixed on a concrete foundation to ensure levelness and straightness.

[0087] Optionally, the platform body 211 includes: a load-bearing component 2111 and multiple sets of wheels 2112 disposed below the load-bearing component 2111;

[0088] The load-bearing component 2111 is equipped with a coaxial encoder, which is used to detect the number of revolutions of at least one wheel 2112 among multiple sets of wheels 2112; when the distance value corresponding to the number of revolutions of at least one wheel 2112 is equal to the preset step distance, the platform body 211 stops running.

[0089] In this implementation, the load-bearing component 2111 can be made of high-strength steel, supporting vehicle models no less than 13m in length, and the size of the load-bearing component 2111 can be customized according to vehicle model requirements.

[0090] The number of multiple sets of wheels 2112 can be eight, evenly distributed on both sides of the load-bearing component 2111, as shown in the attached figure. Figure 4 As shown, it can reciprocate on the track 212 below. The wheel 2112 can be made of cast steel or forged steel, with surface hardening treatment. The diameter of the wheel 2112 can be 0.5-0.6 meters, and heavy-duty roller bearings are selected.

[0091] Furthermore, a coaxial encoder is installed on the load-bearing component 2111. The number of revolutions of the wheels 2112 in the platform body 211 can be detected by the coaxial encoder, thereby calculating the travel distance of the platform body 211.

[0092] Optionally, the mobile platform-based automated loading system may also include: a controller;

[0093] The aforementioned truck scale 24 is positioned above the load-bearing component 2111 to support the loading vehicle and weigh it. When the current weight of the loading vehicle equals the target weight, the controller prompts the loading vehicle to leave the mobile platform 21.

[0094] In this implementation, the load-bearing component 2111 can be designed to partially enclose the truck scale 24, with the truck scale 24 carrying the loading vehicle, thereby weighing the loading vehicle in real time; then, when the current weight value of the loading vehicle is equal to the target weight value, the controller prompts the loading vehicle to leave the mobile platform 21. This prompt can be made by sending information to the driver's terminal, or by sending information through the corresponding display unit or audio unit.

[0095] It should be understood that the controller can be set in the volume detection device 23, the drive device 22, or the moving platform 21; or it can be a standalone device. Correspondingly, the controller can also obtain the current material height value obtained by the volume detection device 23 and control the driving status of the drive device 22. The hardware is also connected.

[0096] Optionally, the platform body 211 may also include: a brake;

[0097] The brake is located on at least one wheel 2112 and is used to brake the platform body 211; the controller is connected to the brake and is used to transmit braking signals to the brake.

[0098] In this implementation, the platform body 211 is equipped with a brake to ensure that the platform body 211 does not slide when it stops.

[0099] Optionally, the mobile platform-type automated loading system also includes: a limit unit 27;

[0100] Limiting units 27 are installed at both ends of the track 212 to limit the range of movement of the platform body 211.

[0101] In this implementation, the limiting unit 27 is set at both ends of the track 212. When the drive device 22 continues to drive the platform body 211 to run, or when a malfunction occurs, this design can prevent the platform body 211 from leaving the track.

[0102] Optionally, the mobile platform-type automated loading system also includes: a through-beam light curtain 25;

[0103] The through-beam light curtain 25 is installed on both sides of the mobile platform 21 to detect the current position of the loading vehicle relative to the material bin 1; when the current position of the loading vehicle is at the target position, the controller prompts the loading vehicle to park in compliance with regulations.

[0104] In this implementation, a through-beam light curtain 25 is used to detect the parking alignment of the loading car relative to the unloading port. It is installed on both sides of the channel below the unloading port. When the front and rear sides of the car body approach the unloading port, the front and rear position distance of the car body relative to the unloading port can be detected.

[0105] Furthermore, when the current position (i.e., the distance between the front and rear positions) is at the target position, the controller controls the drive component 223 to stop, so that the platform body 211 stops, and then the unloading operation is realized.

[0106] Optionally, the mobile platform-type automated loading system also includes: a vehicle authentication unit 26, which includes at least one of the following: a barcode scanner, a card reader, or a barcode scanner and card reader.

[0107] The vehicle authentication unit 26 is set at the first position corresponding to the cab at the initial stop position of the vehicle, and is used to obtain the current model of the loading vehicle; the controller is used to determine the control parameters according to the current model, and the control parameters include at least one of the following: preset step distance, target material pile height value, and target weight value.

[0108] In this implementation, a barcode scanner, card reader, or barcode scanner / card reader combo machine is used to verify vehicle identity. It is installed in the driver's cab at the initial parking position and supports integrated circuit (IC) card swiping and / or QR code scanning.

[0109] Optionally, the mobile platform-based automated loading system may also include: interactive equipment; for setting control parameters for the controller.

[0110] In this implementation, the interactive device can be a touch screen display, which serves as a human-computer interaction interface. The interface is simple and intuitive, and is used to set control parameters such as target weight, step size, and speed.

[0111] In one possible implementation, the interactive device can be a controller with an operating interface or operating buttons.

[0112] Optionally, a drainage groove is provided on the upper surface of the mobile platform 21.

[0113] In this implementation, the mobile platform 21, specifically the bearing component 2111, is designed with drainage grooves on its surface to prevent water accumulation. In some implementations, the mobile platform-type automated loading system can be installed underground so that the surface of the mobile platform-type automated loading device is flush with the ground. At the installation location of the mobile platform-type automated loading system, a trench and a hoist pump can be designed in the foundation pit to prevent water accumulation.

[0114] In addition, the mobile platform-type automated loading system can also be equipped with safety features such as emergency stop buttons, overload protection, and limit protection to ensure the safe operation of the system.

[0115] It should be understood that the dashed lines in the attached diagram represent the area before or after the mobile platform 21 moves with the relevant units.

[0116] This utility model provides a mobile platform-type automatic loading system. The driving device includes a steel wire rope, guide pulleys, and a driving assembly. The steel wire rope is wound in a loop around the mobile platform via the guide pulleys, used to traction the platform. The driving assembly is connected to the steel wire rope and used to traction the steel wire rope. The mobile platform includes a platform body and a track. The track is located below the platform body to guide its direction of movement. In this design, the steel wire rope traction method combined with the pulley system achieves long-distance power transmission and amplification, resulting in a simple structure and high driving force. The track guidance effectively prevents the trolley from deviating, improving movement accuracy and overall stability. This system ultimately achieves reliable and controllable intermittent step-by-step traction for heavy-duty loading vehicles, providing core power support for automated and uniform loading.

[0117] This utility model provides a mobile platform-type automatic loading system. The drive device includes a steel wire rope, a guide pulley, and a drive assembly. The steel wire rope is wound in a loop around the mobile platform via the guide pulley, used to traction the mobile platform. The drive assembly is connected to the steel wire rope and used to traction the steel wire rope. The mobile platform includes a platform body and a track. The track is located below the platform body and used to guide the running direction of the platform body. In this solution, the drive device tractions the steel wire rope through the drive assembly. The guide pulley and track work together to efficiently convert the traction force into directional linear motion of the mobile platform, ensuring stable platform operation, precise guidance, and reliable traction force transmission.

[0118] Based on the above embodiments, an operational scenario flow for a mobile platform-based automated loading system can also be provided, namely:

[0119] 1) After the empty vehicle arrives, it drives onto the weighbridge 24 and stops at the card-swiping and barcode-scanning integrated box; the driver verifies the vehicle identification by swiping a card or scanning a barcode to obtain vehicle information.

[0120] 2) The vehicle information includes the target load and the length, width and height of the cargo box. After the information is verified by swiping a card or scanning a code, the vehicle is weighed and the tare weight is recorded.

[0121] The target gross weight is calculated based on the tare weight and the target load, and is used for weighing on the truck scale 24. Based on the target load and the length, width, and height of the truck bed, the target material pile height and the preset step distance for each platform movement are calculated.

[0122] 3) The position information of the front side of the vehicle is detected by the through-beam light curtain 25, and the platform body 211 is started so that the discharge chute of the material bin is aligned with the set area of ​​the front side of the vehicle. At this time, the platform body 211 stops.

[0123] 4) Control the start of material feeding, and simultaneously detect the material pile height via millimeter-wave radar. When the material pile height reaches the target height, control the platform to move forward a calculated step distance and then stop. Afterward, continue monitoring the material pile height via radar, repeating the step-by-step movement logic.

[0124] 5) The process continues in a step-by-step logical loop until the weight on the truck scale 24 reaches the target gross weight, or until the rear of the truck is detected to have reached the discharge port position by the through-beam light curtain 25. At this point, the system automatically closes and stops discharging. Loading of the truck is complete; the gross weight is recorded.

[0125] 6) The platform body 211 moves forward to the vehicle exit end, where the driver can drive the vehicle away. Afterward, the platform body 211 moves back to the vehicle entry end to wait for the next vehicle. This cycle repeats for each vehicle, achieving fully automated loading.

[0126] It should be understood that the positional relationship between the various units in the accompanying drawings of this utility model embodiment is only an example. In actual implementation, due to the complexity of the unit hardware and the complexity of the actual scene, its installation position is not limited, that is, the function shown in the embodiment can be achieved.

[0127] The various embodiments or implementation methods described in this specification are presented in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the embodiments can be referred to each other.

[0128] It should be noted that the embodiments referred to in the specification, such as "one embodiment," "embodiment," "exemplary embodiment," and "some embodiments," may include specific features, structures, or characteristics, but not every embodiment necessarily includes that specific feature, structure, or characteristic.
