Description

Technical Field

[0001] This invention relates to the field of mobile intelligent online coal quality detection technology, and more specifically to a vehicle-mounted mobile intelligent online coal quality detection device for use in open-pit mines. Background Technology

[0002] In recent years, with the increasingly standardized intelligent management of major coal and power groups, coal mining enterprises have placed greater emphasis on coal quality control. From the perspective of open-pit coal mines, relying solely on laboratory data for coal quality control is a simplistic approach. Especially with the continuous mining in open-pit mines, geological conditions are becoming increasingly complex, leading to significant fluctuations in raw coal quality and making it difficult to guarantee the quality of transported commercial coal. Traditional manual testing methods are labor-intensive, have poor representativeness, and the data is often outdated and susceptible to human error. These methods are no longer suitable for the demands of fast and efficient on-site production processes. Therefore, there is an urgent need for a "vehicle-mounted mobile intelligent coal quality rapid testing device" based on intelligent management in open-pit mines to achieve rapid online testing of coal quality throughout the entire process. Summary of the Invention

[0003] In view of this, the present invention provides a vehicle-mounted mobile intelligent online coal quality detection device for use in open-pit mines.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: Includes: a testing vehicle, a coal quality testing unit installed on the cargo compartment of the testing vehicle, a mechanical execution unit, a system control box, and a host computer; The coal quality testing unit is an independent coal quality testing instrument, which is fixed to the rear of the testing vehicle's cargo compartment by a mounting bracket, and a coal quality testing host is installed inside; the mechanical execution unit is a drilling robotic arm, which is fixed to the bottom of the testing vehicle's cargo compartment by a mounting bracket; the host computer is an industrial control touch screen all-in-one machine, which has a built-in online coal quality testing system, and is fixed to the front of the coal quality testing instrument by a mounting bracket; the system control box is fixed to the left rear side of the cargo compartment by a box hook.

[0005] Furthermore, the mechanical execution unit includes a detection robotic arm and a drilling machine. The detection robotic arm is installed inside the carriage via a slide rail, which is fixedly installed at the bottom of the carriage.

[0006] Furthermore, the coal quality testing unit is a coal quality tester, which is fixed inside the testing robotic arm by a mounting bracket, and the testing robotic arm has a tester window on its exterior.

[0007] Furthermore, the drilling machine is mounted on the bottom of the inspection vehicle's cargo compartment via a slide rail, and a detection hole is provided in the middle of the cargo compartment. The detection hole is a circular hole, and the system control box is installed on the left rear side of the inspection vehicle's cargo compartment.

[0008] Furthermore, the mechanical execution unit includes a lift and a six-axis robotic arm. The lift (13) is fixed to the middle and rear of the carriage. The six-axis robotic arm is fixed above the lift. The coal quality detection unit is a coal quality detector, which is installed at the front end of the six-axis robotic arm.

[0009] Furthermore, the system control box is fixedly installed on the left rear side of the vehicle compartment, and a host computer is installed in the driver's cab of the detection vehicle.

[0010] Furthermore, the bottom of the elevator is provided with fixing holes for fixing to the carriage.

[0011] Furthermore, the inner diameter of the detection hole is 30cm-32cm.

[0012] Compared with existing technologies, this method significantly improves the timeliness and guiding value of detection data. Real-time or near-real-time coal quality data can be directly and quickly fed back to the production control system, providing immediate data support for coal mining, blending, washing, and other processes, thus achieving precise quality control. Automated processes avoid human error, and high-precision detection instruments ensure the objectivity and accuracy of the data, effectively guaranteeing the quality of marketable coal.

The coal quality testing unit is an independent coal quality detector 2, which is fixed to the rear of the vehicle compartment 3 of the testing vehicle 1 by a mounting bracket. A coal quality testing host 4 is installed inside the coal quality detector 2, and a detection inlet 5 is provided on the left side of the coal quality detector 2, and a detection outlet 6 is provided on the right side.

[0018] The mechanical execution unit is a drilling robotic arm 7, which is fixedly installed at the front bottom of the carriage 3 of the testing vehicle 1 via a mounting bracket. The host computer 8 is an industrial control touch screen all-in-one machine, which is fixedly installed on the front side of the coal quality analyzer 2 via a mounting bracket. The system control box 9 is fixedly installed on the left rear side of the carriage 3 via a box hook. The coal quality analyzer 2 can quickly measure ash content, moisture, sulfur content, calorific value, and volatile matter data, and can be, but is not limited to, reflective X-ray online coal quality testing technology, transmission X-ray online coal quality testing technology, natural gamma-ray measurement method, dual-energy gamma-ray transmission measurement method, X-ray fluorescence analysis method, laser-induced breakdown spectroscopy analysis, near-infrared technology measurement method, fusion spectroscopy measurement method, and neutron activation transient gamma-ray detection technology, etc.

[0019] Workflow Step 1: Drive the inspection vehicle 1 to the coal seam above the inspection point, and park the inspection vehicle 1 near the inspection point to ensure that the drilling robotic arm 7 can reach the position to be inspected.

[0020] Step 2: Use button 9 on the system control box to start the drilling robotic arm 7 and drill the coal sample at the detection point.

[0021] Step 3: The coal sample obtained by drilling is placed at the detection inlet 5 by the drilling robotic arm 7.

[0022] Step 4: Send the sample into the coal quality analyzer 2 through the system control box 9. It will automatically stop when it reaches the bottom of the coal quality analyzer 2.

[0023] Step 5: Control the main unit of the detector to start detecting the sample via the host computer 8. The detection time is five minutes.

[0024] Step 6: After the sample testing is completed, the data can be displayed directly on the host computer 8, or transmitted to the on-site centralized control system via the network.

[0025] Step 7: After the test is completed, the sample is sent to the test outlet 6 by the drilling robot arm 7 to complete one test process.

[0026] Data generation and processing: When the coal to be tested enters the coal quality analyzer 2 through the detection inlet 5, the coal quality analyzer 2 (mainly using reflective X-ray technology) begins to scan the coal with X-rays. After the detector receives the X-ray signal, it performs analysis and processing. The host computer 8 analyzes the ash content, moisture content, and calorific value of the coal (hereinafter referred to as data) through the software system algorithm.

[0027] The data can be displayed directly on the host computer software interface or transmitted to the central control system via wireless network. The central control operator and other relevant personnel can directly observe the detection data, and relevant staff can determine the next mining plan based on the detection data.

[0028] Example 2 The difference between this embodiment and the above embodiments lies in the more detailed description of the structure of the device in another operating state, such as... Figure 2 As shown, a vehicle-mounted mobile intelligent online coal quality testing device for use in open-pit mines includes: a testing vehicle 1, a coal quality testing unit installed on the testing vehicle 1 for testing coal samples, a mechanical execution unit installed on the testing vehicle 1 for performing sampling or positioning operations on coal samples, a system control box 9 and a host computer 8 installed on the testing vehicle 1, wherein the host computer 8 has a built-in online coal quality testing system.

[0029] The mechanical execution unit includes a detection robotic arm 15 and a drilling machine 10. The detection robotic arm 15 is installed in the carriage 3 via a slide rail, which is fixedly installed at the bottom of the carriage 3. The coal quality detection unit is a coal quality detector 2, which is installed inside the detection robotic arm 15 via a mounting bracket. The detection robotic arm 15 has a detector window 11 on its exterior.

[0030] The drilling machine 10 is mounted on the bottom of the carriage 3 of the inspection vehicle 1 via a slide rail. A detection hole 12 is provided in the middle of the carriage 3. The detection hole 12 is a circular hole with an inner diameter of 30cm-32cm. The system control box 9 is fixedly installed on the left rear side of the carriage 3 of the inspection vehicle 1.

[0031] Workflow Step 1: Drive the testing vehicle 1 to the coal seam to be tested; Step 2: Drilling machine 10 starts drilling coal seam cores. After drilling, it is moved to the side and the drilled cores are put into the external coal bucket. Step 3: The robotic arm 15 moves the coal quality analyzer 2 to the side of the borehole and delivers the coal quality analyzer 2 into the hole after core drilling to test the rock wall.

[0032] Step 4: The host computer 8 is located in the driver's cab and can view the detected data in real time and transmit it to the corresponding system.

[0033] Data generation and processing: Drilling machine 10 moves to the detection hole 12 via a slide rail. After reaching the position, drilling machine 10 drills a hole in the coal seam through the detection hole 12. After drilling, it returns to its original position via the slide rail. The coal core in the detection hole 12 can be placed under the vehicle and collected in a bucket. The detection robotic arm 15 moves to the detection hole 12 under the vehicle via a slide rail. The detection robotic arm 15 penetrates into the coal seam through the detection hole 12 under the vehicle. After the coal quality detector 2 reaches the coal seam, it can automatically turn on the X-ray. The coal quality detector 2 (mainly a reflective X-ray detector) scans the entire cross-section of the hole through X-ray drilling. After the detector receives the signal returned by the X-ray, it analyzes and processes it. The host computer 8 analyzes the ash content, moisture content, and calorific value of the coal (hereinafter referred to as data) through the software system algorithm.

[0034] The data can be displayed directly on the host computer software interface or transmitted to the central control system via wireless network. The central control operator and other relevant staff can directly observe the detection data and determine the next mining plan based on the detection data.

[0035] Example 3 The difference in this embodiment is that the location of the coal is different from that in the above embodiments. A vehicle-mounted mobile intelligent online coal quality detection device for open-pit mines includes: a detection vehicle 1, a coal quality detection unit installed on the detection vehicle 1 for detecting coal samples, a mechanical execution unit installed on the detection vehicle 1 for performing sampling or positioning operations on coal samples, a system control box 9 and a host computer 8 installed on the detection vehicle 1, wherein the host computer 8 has a built-in online coal quality detection system.

[0036] The mechanical execution unit includes a lift 13 and a six-axis robotic arm 14. The lift 13 is fixedly installed in the middle and rear part of the carriage 3, and the six-axis robotic arm 14 is fixedly installed above the lift 13. The coal quality testing unit is a coal quality detector 2, which is fixed to the front end of the six-axis robotic arm 14 via a connecting seat. The system control box 9 is fixedly installed on the left rear side of the carriage 3. A host computer 8 is installed in the driver's cab of the testing vehicle 1, and the bottom of the lift 13 is provided with fixing holes for fixing to the carriage 3.

[0037] Step 1: Drive the vehicle to the side of the coal seam; Step 2: The elevator is raised to level 13; Step 3: The six-axis robotic arm 14 drives the coal quality analyzer 2 to the detection point; Step 4: After the coal quality analyzer 2 reaches the position, it will begin coal quality testing; Step 5: The host computer 8 is installed in the driver's cab, which can view the detected data in real time and transmit it to the designated coal quality system.

[0038] Data generation and processing: After the six-axis robotic arm 14 moves the coal quality detector 2 to the detection point (the detection point can be located manually, automatically by inputting coordinates, or automatically by locating the detection point according to the coordinates on the mining area map), the location of the detection point can be manually controlled. After the coal quality detector 2 arrives at the detection point, the X-ray can be manually turned on through the system control box 9. The coal quality detector 2 (mainly a reflective X-ray detector) scans the coal seam with X-rays. After the detector receives the signal returned by the X-rays, it is analyzed and processed. The host computer 8 analyzes the ash content, moisture content, and calorific value of the coal (hereinafter referred to as data) through the software system algorithm.

[0039] Data can be directly displayed on the host computer software interface or transmitted to the centralized control system via wireless network. The control operator and relevant personnel can directly observe the detection data and determine the next mining plan based on it. This device is not limited to use in open coal mines; it can also be used in non-coal mining industries such as metal mines, copper mines, aluminum mines, manganese mines, and iron mines.
