Description

Technical Field

[0001] This utility model relates to the field of ore transportation technology, and in particular to an underground loading and unloading human-machine interaction system. Background Technology

[0002] With the development of mining technology, mining enterprises have increasingly higher requirements for production efficiency, data accuracy, and operational safety. To meet these demands, some mining enterprises have introduced cloud-based intelligent logistics systems for mining, which automate the collection and processing of production statistics and backfill data. However, the original production statistics process relied on underground dispatchers using handheld devices to swipe cards for dispatching goods, and drivers using self-service weighbridges on the surface to swipe cards for weighing to complete data entry. For backfill loading, dispatchers and receivers also needed to swipe cards on-site for dispatching and receiving operations. This traditional working method has the following problems:

[0003] 1. According to safety production regulations, delivery personnel and drivers in the mine should not get out of the vehicle when performing tasks in order to reduce the occurrence of accidents. The original system requires staff to get out of the vehicle to complete specific business operations, which not only increases the difficulty of the work, but also brings potential safety risks. Especially in the poor visibility, damp and dusty underground environment, staff are prone to make mistakes, resulting in equipment damage or personal injury.

[0004] 2. Due to human intervention, such as the frequent occurrence of misclassification of low-grade and high-grade ores, data recording errors are directly caused. Furthermore, the extensive use of equipment complicates equipment management and maintenance, increasing the risk of incorrect equipment coding configurations and consequently affecting the accuracy of the final statistical data.

[0005] 3. Traditional ore loading processes typically rely on manually controlled gate valves for ore discharge. This involves operators estimating the loading volume based on experience and then weighing it to confirm the result. If the weight does not meet the specified standards, the loading volume must be adjusted and the weight re-weighed. This process is repeated, which not only prolongs the loading cycle and reduces weighing efficiency but also requires additional loading equipment and multiple shift operators on-site, increasing the company's operating costs. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide an underground loading and unloading human-machine interaction system. The system should be able to realize automated data entry and cargo loading and unloading operations without getting off the vehicle, while ensuring data accuracy, improving work efficiency, adapting to harsh working environments, and conforming to the national mechanization and automation development direction.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A human-machine interaction system for loading and unloading goods in an underground mine includes a main mine road, a branch mine road, and an in-vehicle interaction unit. The branch mine road is vertically connected to the side of the main mine road. A first gate, a second gate, and a third gate are sequentially arranged on the side of the main mine road. A first external interaction unit is arranged on the side of the first gate, and a second external interaction unit is arranged on the side of the third gate. An in-vehicle interaction unit is arranged inside the material transport trolley and is wirelessly connected to the first and second external interaction units.

[0009] In a preferred embodiment, a rotary table is installed on the main road of the mine. The bottom of the rotary table is connected to a hydraulic rotating system and can rotate freely around its own axis. The rotary table is positioned between the first gate and the second gate and connects to the mine branch road.

[0010] In a preferred embodiment, an electronic weighbridge and a telescopic ramp are installed on the main road of the mine. The electronic weighbridge is located in front of the first gate, and the telescopic ramp is located in front of the third gate.

[0011] In a preferred embodiment, a pressure sensor is installed on the upper surface of the telescopic plate.

[0012] In a preferred embodiment, the electronic weighbridge is equipped with a first infrared positioning device on its side and a second infrared positioning device on its side of the telescopic plate. The first infrared positioning device is wirelessly connected to the first vehicle exterior interactive unit, and the second infrared positioning device is wirelessly connected to the second vehicle exterior interactive unit.

[0013] In a preferred embodiment, the in-vehicle interactive unit includes a support column and an in-vehicle interactive screen. The in-vehicle interactive screen is mounted on the dashboard inside the vehicle via the support column. The in-vehicle interactive screen is equipped with a wireless signal transmission device and is wirelessly connected to the first and second external interactive units.

[0014] In the preferred embodiment, LED light strips are laid parallel to each other on both sides of the main mine road and the branch mine road.

[0015] In a preferred embodiment, warning lights are installed on the sides of the first, second, and third turnstiles, and loudspeakers are installed on the sides of the first and second vehicle-to-vehicle interaction units.

[0016] A human-machine interface system for loading and unloading goods in underground mines has the following advantages in actual use:

[0017] 1. The system upgrade eliminated the card-swiping workflow, ensuring that drivers and staff do not need to leave the vehicle during underground operations. All business data interaction is completed via wireless communication (Wi-Fi) technology. This not only simplifies the operation process but also greatly reduces safety hazards caused by leaving the vehicle, improving the safety and standardization of underground operations.

[0018] 2. Work requests are initiated by the driver and can begin after being reviewed by on-site staff. This model reduces repetitive work for staff, and all data feedback is automatically completed after the dispatcher signs in upon leaving the well, eliminating the need for secondary uploading and ensuring the timeliness and accuracy of data feedback, thus improving overall work efficiency.

[0019] 3. The automated data acquisition and transmission mechanism avoids errors that may be caused by manual operation, ensuring high accuracy of production statistics and backfill data. Centralized management and configuration of equipment codes also reduce the risk of coding errors and improve the efficiency of equipment management and data processing.

[0020] 4. The electronic weighbridge, infrared positioning device, pressure sensor and LED light strip in the system provide accurate weighing and good lighting conditions, which improves the working environment underground and ensures the safety of loading and unloading operations.

[0027] like Figure 1 and Figure 2As shown, an underground loading and unloading human-machine interaction system includes a main mine road 1, a branch mine road 2, and an in-vehicle interaction unit 13. The main mine road 1 is vertically connected to the branch mine road 2 on its side. A first gate 4, a second gate 5, and a third gate 6 are sequentially arranged on the side of the main mine road 1. A first external interaction unit 11 is arranged on the side of the first gate 4, and a second external interaction unit 12 is arranged on the side of the third gate 6. An in-vehicle interaction unit 13 is arranged inside the material transport trolley and is wirelessly connected to the first external interaction unit 11 and the second external interaction unit 12.

[0028] When the mine car is loading and unloading materials, it will first pass through the first gate 4. After human-machine interaction and meeting the passage requirements, it will enter the second gate 5 and the third gate 6 in sequence. Each time the car passes through a gate, the driver needs to swipe the card to confirm through the in-vehicle interactive machine 13 and interact with the first external interactive machine 11 and the second external interactive machine 12 to ensure the accuracy of loading and unloading.

[0029] Preferred solutions include Figure 1 and Figure 2 As shown, a rotary table 7 is installed on the main road 1 of the mine. The bottom of the rotary table 7 is connected to a hydraulic rotating system and can rotate freely around its own axis. The rotary table 7 is located between the first gate 4 and the second gate 5 and is connected to the mine branch road 2.

[0030] When a mine car passes through the first gate 4 and moves to the front of the second gate 5, the first external intercom 11 will determine in advance whether the mine car meets the requirements for continued passage. If the requirements are met, the second gate 5 will automatically open. If the mine car does not meet the requirements for continued passage, the rotating disc 7 below will start rotating after sensing the mine car above, causing the mine car to rotate in place and reverse direction, and finally exit through the mine branch road 2. Through the above system, the mine car can pass quickly in a narrow space, which is suitable for working in narrow mines and ensures the continuity of loading and unloading in the mine.

[0031] Preferred solutions include Figure 1 and Figure 2 As shown, an electronic weighbridge 3 and a telescopic plate 8 are installed on the main road 1 of the mine. The electronic weighbridge 3 is located in front of the first gate 4, and the telescopic plate 8 is located in front of the third gate 6. When the mine car travels to the front of the first gate 4, the electronic weighbridge 3 will accurately weigh it and display the value in real time on the first external interactive machine 11 and the internal interactive machine 13. When the mine car moves to the front of the third gate 6 and needs to be unloaded, the telescopic plate 8 will retract inward under the drive of the hydraulic system, and an unloading port will appear below the main road 1 of the mine. The mine car body can then be tilted backward to unload the ore through the unloading port.

[0032] Preferred solutions include Figure 2As shown, a pressure sensor 19 is installed on the upper surface of the telescopic plate 8. When there is pressure input on the pressure sensor 19, the transmission mechanism inside the telescopic plate 8 is in a linked locked state to prevent the unloading port from suddenly opening and causing a safety accident when the trolley travels above the telescopic plate 8.

[0033] Preferred solutions include Figure 2 As shown, the electronic weighbridge 3 is equipped with a first infrared positioning device 9 on its side, and the telescopic plate 8 is equipped with a second infrared positioning device 10 on its side. The first infrared positioning device 9 is wirelessly connected to the first vehicle external communication device 11, and the second infrared positioning device 10 is wirelessly connected to the second vehicle external communication device 12. The above devices can assist the mine car in positioning itself on the designated electronic weighbridge 3 and in front of the unloading port, enabling the mine car to perform accurate weighing and unloading operations.

[0034] Preferred solutions include Figure 3 As shown, the in-vehicle interactive unit 13 includes a support column 14 and an in-vehicle interactive screen 15. The in-vehicle interactive screen 15 is mounted on the driver's dashboard inside the vehicle via the support column 14. The in-vehicle interactive screen 15 is equipped with a wireless signal transmission device and is wirelessly connected to the first external interactive unit 11 and the second external interactive unit 12.

[0035] Whenever a mine car passes through the gate, the interactive screen 15 inside the car displays real-time command operation options. The driver performs human-machine interaction tasks such as swiping a card inside the car, and all business data interaction is completed through wireless communication (Wi-Fi) technology. This not only simplifies the operation process but also greatly reduces the safety hazards caused by getting out of the car to operate, improving the safety and standardization of underground operations.

[0036] Preferred solutions include Figure 3 As shown, LED light strips 18 are laid parallel to each other on both sides of the main road 1 and the branch road 2 of the mine. The LED light strips 18 can assist the mine car to travel along the designated route, ensuring that the mine car can travel safely along the designated route in the dim space.

[0037] Preferred solutions include Figure 4 As shown, warning lights 17 are installed on the sides of the first gate 4, the second gate 5 and the third gate 6, and loudspeakers 16 are installed on the sides of the first vehicle external interface 11 and the second vehicle external interface 12.

[0038] During the unloading process, the truck displays the information through the second external intercom 12, allowing the driver to stay informed about the unloading status. Once the unloading is complete, the unloading stops immediately, the third gate 6 opens, and the loudspeaker 16 calls the driver to leave the unloading point. When the mine car passes through the first gate 4, the second gate 5, and the third gate 6 and does not meet the requirements for continued passage, the warning light 17 will flash immediately, and a warning will also be issued through the internal intercom 13, notifying the mine car to leave the site immediately.

[0039] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
