Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ore transportation, in particular to an underground mine weighing system. Background Art
[0002] In underground mining operations, traditional production statistics and logistics management processes require vehicles to travel to the surface or to the wellhead for weighing. This not only increases transportation distance and time costs, but also leads to data deviations due to fixed tonnage estimates, making accurate measurement impossible. More critically, the visibility in the mine is dim, the space is narrow, and the mine cars are large, making it easy for safety accidents such as scratches or collisions to occur, seriously affecting operational efficiency and safety. These problems limit the refined management of mine production and the improvement of operational efficiency. These deficiencies in existing technologies, especially the difficulty in installing large-scale scales in the narrow underground environment and the resulting safety risks and inaccurate measurements, have become technical problems that need to be solved urgently. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide an underground mine weighing system that accurately measures the materials loaded on transport vehicles. Furthermore, the system incorporates technologies such as wireless communication, intelligent scheduling, and enhanced lighting to optimize the mine vehicle's travel path, improve operational safety and efficiency, and meet the needs of refined mine management in modern mines.
[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:
[0005] An underground mine weighing system includes a main channel, a chamber channel and an axle weight scale. The main channel is provided in the mine, and the side of the main channel is vertically connected to the chamber channel. The axle weight scale is laid on the chamber channel. A rotating disk is laid on the ground of the main channel, and the rotating disk is arranged at the connection between the main channel and the chamber channel. A conveyor belt is also laid on the ground of the main channel, and the conveyor belt is arranged between the rotating disks.
[0006] In a preferred solution, a gate is provided in front of the axle weight scale, and an interactive machine is provided on the side of the axle weight scale. The interactive machine is electrically connected to the axle weight scale via a data line.
[0007] In a preferred solution, a display screen is provided on the wall of the chamber of the main passage, the display screen is electrically connected to the interactive machine via a data line, and the display screen is connected to the remote monitoring center via a wireless signal.
[0008] In a preferred solution, an infrared position sensor is provided on the side of the axle weight scale, and a signal light is provided on the gate and connected to the axle weight scale via a signal line.
[0009] In a preferred solution, LED light strips are laid on both sides of the chamber passage, and the spacing between the LED light strips is greater than the wheelbase of the mine car.
[0010] In a preferred solution, a pressure sensor is provided on the upper end surface of the rotating disk, and the pressure sensor is electrically interlocked with the driving device of the conveyor belt.
[0011] An underground mine weighing system, the external system has the following advantages in actual use:
[0012] 1. By installing an axle weight scale in the chamber passage, weighing can be completed directly at the unloading chute, avoiding data deviation caused by fixed tonnage estimation in traditional methods. This ensures that the actual load of each mine car is accurately measured, thereby improving the accuracy of production statistics.
[0013] 2. A rotating disk and conveyor belt are installed at the connection between the main passage and the chamber passage, so that the mine car can flexibly turn direction in a limited space, reducing unnecessary round-trip distance, optimizing the logistics path, and reducing transportation costs and time consumption;
[0014] 3. The spacing between the LED light strips on both sides of the chamber passage is greater than the wheelbase of the mine car, ensuring sufficient light to illuminate the surrounding environment when the mine car is driving, reducing the risk of scratches or collisions. In addition, the installation of gates, infrared position sensors and signal lights further ensures the orderly passage of mine cars, improving the level of operational safety.
[0015] 4. The electrical connection between the interactive machine and the axle load scale, as well as the wireless signal connection between the display and the remote monitoring center, enable real-time collection, transmission, and remote monitoring of on-site data. Managers and mine car drivers can keep abreast of the mine car's operating status and material information, facilitating refined management and decision-making support.

The main channel 1 is provided in the mine, and the side of the main channel 1 is vertically connected to the chamber channel 3. The axle weight scale 12 is laid on the chamber channel 3. A rotating disk 2 is laid on the ground of the main channel 1. The rotating disk 2 is arranged at the connection between the main channel 1 and the chamber channel 3. A conveyor belt 4 is also laid on the ground of the main channel 1. The conveyor belt 4 is arranged between the rotating disks 2.
[0021] When loading and unloading materials underground, the mine car is mainly operated in the mine chamber. After loading and unloading, it is accurately measured by the axle weight scale 12, then enters the rotating disk 2 on the main channel 1 and turns direction, and finally the mine car is transported out of the mine chamber by the conveyor belt 4.
[0022] The preferred solution is Figure 2 As shown, a gate 8 is provided in front of the axle weight scale 12, and an interactive machine 7 is provided on the side of the axle weight scale 12. The interactive machine 7 is electrically connected to the axle weight scale 12 through a data cable; after loading and unloading, the mine car will pass through the axle weight scale 12 and come to the front of the gate 8. The gate 8 will display the real-time axle weight of the mine car, and will only be opened and released if the requirements are met.
[0023] The preferred solution is Figure 1 As shown, a display screen 5 is provided on the wall of the chamber of the main channel 1, and the display screen 5 is electrically connected to the interactive machine 7 through a data line, and the display screen 5 is connected to the remote monitoring center by wireless signal; the interactive machine 7 will display the weighed axle seat and the scanned mine car license plate on the display screen 5 in real time, and the mine car driver can grasp the working conditions of each chamber underground in real time. At the same time, the display screen 5 will also send the collected data to the remote monitoring center through a wireless signal transmission device, so as to realize centralized monitoring of underground weighing in the mine area. On the basis of unattended weighing and measurement, the LED display screen 5 equipment is cooperated to realize large-screen real-time monitoring and remote control; at the same time, data production statistics can be viewed in real time through system reports, and mine area managers can accurately count the real-time production data of each team through the platform.
[0024] The preferred solution is Figure 2 As shown, an infrared position sensor 6 is provided on the side of the axle load scale 12, and a signal light 9 is provided on the gate 8 and is connected to the axle load scale 12 signal; under normal circumstances, the signal light 9 is displayed as a red light.

[0025] The preferred solution is Figure 2As shown, LED light strips 11 are laid on both sides of the chamber passage 3. The spacing between the LED light strips 11 is greater than the wheelbase of the mine car.

Only when the mine car leaves the rotating disk 2 and enters the conveyor belt 4, the electrical interlock will be released. The above structure can effectively avoid collisions between the front and rear vehicles, optimize the driving path of the mine car, and improve the safety and efficiency of the operation.
