[0026] The wide-band conveyor unloading vehicle proposed in this invention is suitable for industrial fields such as coal mines, ports, metallurgy, power, and sand and gravel aggregates that require precise material transportation. It can solve the problems of insufficient turning flexibility and limited material placement path of existing unloading vehicles in curved track scenarios, thereby enabling flexible turning and flexible material placement on curved tracks, reducing equipment friction wear, and helping to extend the service life of the equipment.

[0027] Please combine Figure 1 and Figure 2The wide-band conveyor unloading vehicle includes a frame and a steering mechanism and control system 15 mounted on the frame. The steering mechanism includes several steering wheel sets; each steering wheel set includes a steering wheel axle 6, a steering wheel 5, a steering adjustment component, a first driver 1, and a second driver 8. The steering wheel 5 is located at both ends of the steering wheel axle 6. The first driver 1 is connected to the steering adjustment component, which is connected to the steering wheel 5, driving the steering wheel 5 to turn. The second driver 8 is connected to the steering wheel 5, driving the steering wheel 5 to rotate. The control system 15 is connected to the steering adjustment component, the first driver 1, and the second driver 8. The control system 15 can pre-store or detect the curvature of the track and control the steering adjustment component according to the track curvature to make the steering wheel 5 rotate at a preset angle. This preset angle is the optimal angle under dynamic conditions to reduce wear on the steering wheel 5 and the track sidewalls, achieve flexible steering, and extend the service life of the equipment.

[0028] Optionally, the steering adjustment assembly includes a first reducer 2, a lead screw 3, and a steering knuckle 4. The first drive 1 is connected to the first reducer 2, the first reducer 2 is connected to the lead screw 3, the lead screw 3 is connected to the steering knuckle 4, and the steering knuckle 4 is connected to the steering wheel axle 6. In this embodiment, the steering knuckle 4 and the steering wheel axle 6 are connected by bearings.

[0029] In this embodiment, the steering wheel 5 is made of wear-resistant material to ensure good contact with the track and a long service life. The first drive unit 1 is a steering motor. All steering motors are miniaturized, high-precision motors capable of providing sufficient steering force. The first reducer 2 uses a reduction gearbox to convert the rotational motion of the steering motor into the linear movement of the lead screw 3, which drives the steering knuckle 4. The steering knuckle 4 is connected to the steering wheel shaft 6, thus realizing the rotation of the steering wheel 5. It can be understood that the steering wheel 5 is connected to the steering knuckle 4 via the steering wheel shaft 6, and the steering knuckle 4 and the steering wheel shaft 6 are connected by bearings to ensure steering flexibility.

[0030] The second drive unit 8 uses a drive motor. The second drive unit 8 is connected to the second reducer 10, and the second reducer 10 is connected to the steering wheel 5. Specifically, the steering mechanism also includes an axle 9, one end of which is connected to the steering wheel 5, and the other end is connected to the second drive unit 8. The steering wheel 5 is connected to the second reducer 10 via the axle 9. A frame connector 101 is provided on the steering wheel axle 6, which is connected to the steering wheel axle 6 to improve connection stability. The frame connector 101 is used to fix the steering mechanism to the frame. The drive motor is a high-power motor capable of providing sufficient traction. The second reducer 10 is used to reduce the speed of the drive motor and increase torque. Optionally, the drive motor uses frequency conversion control, which can optimize conveying efficiency according to material flow rate and unloading speed.

[0031] It should be noted that each steering wheel 5 is independently equipped with a steering motor and a drive motor, and the two do not interfere with each other. This provides both strong forward driving force to ensure smooth operation even under full load and flexible steering. Optionally, the steering motor is equipped with a first control interface 7, which is connected to the control system 15 to receive commands from the control system 15.

[0032] Of course, in some implementations, the drive motor is also provided with a second control interface, which is connected to the control system 15 and is used to receive instructions from the control system 15. This is not specifically limited here.

[0033] In some embodiments, the steering adjustment assembly includes a differential, and the steering wheel axle 6 includes two half-shafts, each half-shaft being connected to a steering wheel 5. The differential is connected to each half-shaft. The first drive 1 is connected to the differential. By using the differential to control the speed difference between the left and right steering wheels 5, the steering of the unloading vehicle is achieved. This method has a simple structure, low cost, and similar technical effects.

[0034] Please combine Figure 3 and Figure 4 Optionally, the unloading vehicle also includes an unloading mechanism, which includes an unloading arm 11 and an unloading adjustment assembly. The unloading arm 11 is connected to the conveyor belt; the unloading adjustment assembly is connected to the unloading arm 11 to adjust the length and angle of the unloading arm 11. The unloading mechanism is used to unload materials from the conveyor belt to the target position. The adjustable unloading arm 11 allows for adjustment of its length and angle according to actual needs, achieving precise material distribution. The unloading adjustment assembly includes a third driver 12 and a hinge 13. The third driver 12 is connected to the unloading arm 11, and the hinge 13 connects the unloading arm 11 to the vehicle frame. The third driver 12 is connected to the control system 15. In this embodiment, the third driver 12 is a hydraulic cylinder or an electric push rod. The unloading arm 11 is made of high-strength, lightweight material to reduce its weight and energy consumption. The hydraulic cylinder or electric push rod is used to adjust the length and angle of the unloading arm 11. The hinge 13 connects the unloading arm 11 to the vehicle frame, enabling the rotation of the unloading arm 11. Figure 2 and Figure 3 In the figure, angle α represents the rotation angle of the unloading arm 11.

[0035] In this embodiment, the unloading arm 11 is connected to the vehicle frame via a hinge 13. A hydraulic cylinder or electric push rod connects the unloading arm 11 and the vehicle frame, controlling the movement of the unloading arm 11. The third driver 12 is equipped with a third control interface 14, which is connected to the control system 15 to receive commands from the control system 15. The control system 15 controls the extension and retraction of the hydraulic cylinder or electric push rod according to preset unloading positions and material flow rates, adjusting the length and angle of the unloading arm 11 to accurately unload the material to the target position, improving the fabric placement accuracy.

[0036] Please combine Figure 5 The control system 15 is the core component of the unloading vehicle, responsible for coordinating the operation of various mechanisms. Optionally, the control system 15 includes a sensor module 151, a control module 152, and an execution module 153; the sensor module 151 and the execution module 153 are respectively connected to the control module 152. The sensor module 151 is used to detect track curvature, material flow rate, and operating status, etc. The control module 152 is used to receive the signals detected by the sensor module 151 and control the execution module 153 to issue control commands based on the received signals; the execution module 153 is respectively connected to the first driver 1, the second driver 8, and the third driver 12.

[0037] Optionally, the sensor module 151 includes a track curvature sensor, a material flow sensor, and an operating status detection sensor. The track curvature sensor is used to detect the curvature of the curved track 160 in real time. The control module 152 calculates the optimal steering angle for each steering wheel assembly based on the real-time detected curvature of the curved track 160. The execution module 153 controls the steering motor to rotate the steering wheel assembly to the corresponding angle, thereby achieving smooth steering of the unloading vehicle on the curved track 160.

[0038] Of course, in some implementations, the map information of the curved track 160 can be pre-stored in the control module 152. The control module 152 calculates the optimal steering angle for each steering wheel group based on the current position of the unloading vehicle and the pre-stored map information. The execution module 153 controls the steering motor to rotate the steering wheel group to the corresponding angle, thereby achieving flexible and smooth steering. The map information is equivalent to the unloading vehicle's travel path. It is worth noting that if the map information is pre-stored in the control system 15, the track curvature sensor can be omitted. Of course, both pre-stored map information and track curvature sensors can be used; no specific limitation is made here.

[0039] Material flow sensors are used to detect material incoming information on the conveyor belt. Operating status sensors are used to detect information such as the speed, position, and attitude of the unloading vehicle.

[0040] The control module 152 uses a PLC or embedded controller. Based on the information collected by the sensor module 151, it calculates the control parameters of each mechanism and generates control commands. The execution module 153 includes, but is not limited to, a drive motor controller, a steering motor controller, a hydraulic cylinder or electric push rod controller, or other mechanism controllers. Based on the commands from the control module 152, it controls the operation of each mechanism and adjusts the operating parameters of each mechanism.

[0041] It should be noted that the sensor module 151 can collect the operating status, material flow rate, and track information of the unloading trolley in real time and transmit this information to the control module 152. Based on this information and combined with the preset control strategy, the control module 152 calculates the control parameters of each mechanism and controls the operation of each mechanism through the execution module 153, thereby realizing the intelligent control of the unloading trolley and improving steering accuracy and material placement accuracy.

[0042] Optionally, the control system 15 also includes a positioning module, which is used to detect the position of the frame, that is, to obtain the current position of the unloading vehicle in real time, so as to calculate the steering angle and obtain the running status, such as speed and acceleration, thereby improving steering accuracy and material placement accuracy.

[0043] Optionally, the control system 15 also includes a storage module for storing information, including but not limited to storing map information of the curved track 160, the work log of the unloading vehicle, etc.

[0044] Optionally, the control system 15 also includes a remote monitoring module and a mobile terminal. The remote monitoring module is connected to the mobile terminal, which allows operators to monitor the operating status of the unloading vehicle in real time.

[0045] In this embodiment, the conveyor belt is made of high-strength, wear-resistant material to meet the conveying requirements of wide-bandgap materials. The frame is welded from high-strength steel, possessing sufficient strength and rigidity to withstand various loads on the unloading vehicle under full load. The frame structure design fully considers the installation and maintenance space of each mechanism, facilitating equipment maintenance and upkeep. As the carrier supporting and fixing each mechanism, the frame ensures the relative positional relationship between the mechanisms and the overall stability of the unloading vehicle.

[0046] The working principle of the unloading vehicle provided in this embodiment is roughly as follows: Feeding stage: The material is transported to the conveyor belt of the unloading vehicle through the feeding mechanism (such as belt conveyor, hopper, etc.).

[0047] Conveying stage: Driven by the drive motor, the conveyor belt transports the material to the target unloading position.

[0048] Steering control: When the unloading car needs to run on the curved track 160, the control system 15 controls the steering mechanism to adjust the angle of the steering wheel 5 according to the real-time detected track curvature, so as to ensure the smooth steering of the trolley, achieve flexible steering, and improve steering accuracy.

[0049] Unloading process: When the conveyor belt transports the material to the target unloading position, the control system 15 controls the unloading mechanism to adjust the length and angle of the unloading arm 11, so as to accurately unload the material to the target position and improve the fabric distribution accuracy.

[0050] During the movement process: The control system 15 dynamically adjusts the driving force of the steering wheel 5 according to the running status of the unloading vehicle and the track slope, so as to ensure the smooth operation of the unloading vehicle.

[0051] This unloading vehicle is suitable for both wide-band and narrow-band conveyor unloading vehicles. It can be flexibly turned, improving steering and material distribution accuracy, reducing wear on steering wheels and tracks, and extending service life.

[0052] In summary, the wide-band conveyor unloading vehicle provided in this embodiment of the invention has the following beneficial effects, including: In this wide-band conveyor unloading trolley, each steering wheel assembly is equipped with a first drive 1 and a second drive 8. The first drive 1 is used for steering, and the second drive 8 is used for forward propulsion; that is, steering and driving are independent of each other. Furthermore, the control system 15 can pre-store or detect the curvature of the track and control the steering adjustment components according to the track curvature to make the steering wheels 5 rotate at a preset angle. This allows for flexible steering in curved tracks 160° or complex track scenarios, providing strong adaptability, reducing wear on the steering wheels 5 and the track sidewalls, and extending the service life of the equipment. The drive motor is connected to the control system 15 and can dynamically adjust the driving force of the steering wheels 5 according to the unloading trolley's operating status and track slope, ensuring smooth operation even under full load. The adjustment of the unloading arm 11 can be achieved hydraulically or electrically and controlled by the control system 15 to achieve precise material placement. The intelligent control system 15 collects the unloading trolley's operating status and track information in real time through sensors and dynamically adjusts the operating parameters of each mechanism based on this information, improving operating efficiency and accuracy, reducing manual intervention, and enhancing automation and intelligence.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; any modifications, equivalent substitutions, improvements, etc., should be included within the protection scope of the present invention.
