[0001] The invention relates to the technical field of belt conveyors, and in particular to a belt roller device for fracture detection and a detection method thereof. Background Art

[0002] In industrial production, belt conveyors are a common material handling equipment, widely used in mining, ports, grain processing and other industries. As one of the key components of belt conveyors, the normal operation of the belt roller is crucial to the stable operation of the entire system. However, due to long-term use or unexpected factors, the belt roller may break and other faults.

[0005] In order to achieve the above-mentioned invention object, the present invention adopts the following technical scheme: a belt roller device for fracture detection, comprising two mounting seats, the two mounting seats are respectively fixed on the top surface of the base, one side of the two mounting seats is respectively provided with a rotation hole, a DCS controller is fixed on the right side of the outer wall of the base, a first roller is rotatably arranged between the two mounting seats, a rotating shaft is respectively fixed at the left end and the right end of the first roller, and the two rotating shafts are rotatably arranged in two rotating holes, two supporting seats are fixed on the top surface of the base, a second roller is rotatably arranged between the two supporting seats, a belt body is arranged between the second roller and the first roller, a driving motor is fixed on the left side of the mounting seat on the left side, the driving motor is electrically connected to the DCS controller, and the output shaft of the driving motor is fixedly connected to the rotating shaft on the left side, two supporting plates are movably arranged above the base, an infrared transmitter is detachably arranged on the left side of the supporting plate on the right side, and the infrared transmitter is electrically connected to the DCS controller, and an infrared receiver is detachably arranged on the right side of the supporting plate on the left side, and the infrared receiver is electrically connected to the DCS controller.

[0006] Preferably, a first hydraulic push rod is detachably provided on the inner bottom surface of the base, the first hydraulic push rod is electrically connected to the DCS controller, and a U-shaped plate is fixed to one end of the telescopic rod of the first hydraulic push rod.

[0007] Preferably, a rubber pad is fixed to the inner wall of the U-shaped plate.

[0008] Preferably, the top surfaces of the infrared transmitter and the infrared receiver are respectively fixed with fixing plates, the top surfaces of the two support plates are respectively opened with first threaded grooves, the top surfaces of the two fixing plates are respectively opened with first threaded holes, the two first threaded holes are respectively threadedly connected with first bolts, and the threaded ends of the two first bolts are respectively connected with the internal threads of the two first threaded grooves.

[0009] Preferably, two second hydraulic push rods are fixed to the top surface of the base, and one end of the telescopic rods of the two second hydraulic push rods are respectively fixedly connected to the rear sides of the two support plates.

[0010] Preferably, two slide grooves are provided on the top surface of the base, and sliding blocks are respectively fixed on the bottom surfaces of the two support plates, and the two sliding blocks are respectively slidably disposed in the two slide grooves.

[0013] The present invention also provides a detection method for a belt roller device for fracture detection, comprising the following steps:

[0020] 2. During use, it is helpful to reduce the time that the first roller continues to rotate due to inertia, ensuring timely shutdown after the first roller breaks, thereby effectively reducing the risk of scratches on the belt body. A rubber pad is added to the inner wall of the U-shaped plate, which not only increases the friction between the U-shaped plate and the rotating shaft, ensuring the reliability of the shutdown action, but also reduces the wear caused by direct contact, thereby improving the durability and reliability of the device. Through the fixing plate and the first bolt, the staff can easily disassemble and assemble the infrared transmitter and the infrared receiver. The first threaded hole on the fixing plate matches the first threaded groove on the support plate. Tightening or disassembly can be achieved by rotating the first bolt, which improves the flexibility and maintainability of the device and facilitates the staff to replace the infrared transmitter and infrared receiver as needed;

[0021] 3.

DETAILED DESCRIPTION

[0031] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] like Figure 1-Figure 7 As shown, a belt roller device for fracture detection includes two mounting seats 1, the two mounting seats 1 are respectively fixed on the top surface of a base 2, a rotation hole 3 is respectively opened on one side of the two mounting seats 1, a DCS controller is fixed on the right side of the outer wall of the base 2, a first roller 4 is rotatably arranged between the two mounting seats 1, a rotating shaft 5 is respectively fixed at the left end and the right end of the first roller 4, and the two rotating shafts 5 are rotatably arranged in the two rotating holes 3, two supporting seats 6 are fixed on the top surface of the base 2, a second roller 7 is rotatably arranged between the two supporting seats 6, and the second roller 7 and the first roller 4 are provided with a belt body 8, a drive motor 9 is fixed on the left side of the left mounting seat 1, the drive motor 9 is electrically connected to the DCS controller, and the output shaft of the drive motor 9 is fixedly connected to the left rotating shaft 5, two support plates 10 are movably provided above the base 2, an infrared transmitter 11 is detachably provided on the left side of the right support plate 10, the infrared transmitter 11 is electrically connected to the DCS controller, and an infrared receiver 12 is detachably provided on the right side of the left support plate 10, and the infrared receiver 12 is electrically connected to the DCS controller.

[0033] During use, the staff first installs the infrared transmitter 11 and the infrared receiver 12 along the non-contact surface of the first roller 4, and installs them on the left and right sides of the first roller 4 respectively. When working, the staff starts the drive motor 9 to rotate the shaft 5 and the first roller 4, and then drives the belt body 8 and the second roller 7 to rotate. At the same time, the infrared transmitter 11 and the infrared receiver 12 start working to detect the cross-sectional state of the first roller 4 in real time. When the first roller 4 is in a normal state, the infrared receiver 12 can receive the infrared signal from the infrared transmitter 11. When the first roller 4 breaks, the broken part will be displaced due to the extrusion of the belt body 8, blocking the infrared beam, and the infrared receiver 12 cannot receive the infrared signal. When the infrared receiver 12 cannot receive the infrared signal, it will immediately send a status signal to the DCS controller. After judgment, the DCS controller sends a belt conveyor interlocking shutdown command to stop the drive motor 9. After the belt conveyor stops, the belt body 8 will not be scratched, avoiding the expansion of the accident. A status monitoring device is installed at the running position of the first roller 4 to ensure that the first roller 4 can be discovered in time when it breaks, reducing losses.

[0034] like Figure 1 , Figure 2 and Figure 5-Figure 7 As shown, a first hydraulic push rod 13 is detachably provided on the inner bottom surface of the base 2. The first hydraulic push rod 13 is electrically connected to the DCS controller. A U-shaped plate 14 is fixed to one end of the telescopic rod of the first hydraulic push rod 13.

[0035] During use, when the DCS controller receives the status signal from the infrared receiver 12, it will immediately start the first hydraulic push rod 13, and the telescopic rod of the first hydraulic push rod 13 will extend to push the U-shaped plate 14 upward until it contacts the rotating shaft 5 on the right side, which is beneficial to reduce the time that the first roller 4 continues to rotate due to inertia, ensuring timely shutdown after the first roller 4 breaks, thereby effectively reducing the risk of scratches on the belt body 8.

[0036] like Figure 1 , Figure 2 and Figure 4-Figure 7 As shown, a rubber pad 15 is fixed to the inner wall of the U-shaped plate 14, a fixing plate 16 is fixed to the top surface of the infrared transmitter 11 and the infrared receiver 12, respectively, a first threaded groove 17 is opened on the top surface of the two support plates 10, and a first threaded hole 18 is opened on the top surface of the two fixing plates 16, respectively, and a first bolt 19 is threadedly connected in the two first threaded holes 18, and the threaded ends of the two first bolts 19 are respectively connected to the internal threads of the two first threaded grooves 17, and two second hydraulic push rods 20 are fixed to the top surface of the base 2, and one end of the telescopic rods of the two second hydraulic push rods 20 is fixedly connected to the rear sides of the two support plates 10.

[0037] During use, a rubber pad 15 is added to the inner wall of the U-shaped plate 14, which not only increases the friction between the U-shaped plate 14 and the rotating shaft 5, ensuring the reliability of the shutdown action, but also reduces the wear caused by direct contact, thereby improving the durability and reliability of the device. Through the fixing plate 16 and the first bolt 19, the staff can easily disassemble and assemble the infrared transmitter 11 and the infrared receiver 12. The first threaded hole 18 on the fixing plate 16 matches the first threaded groove 17 on the support plate 10. By rotating the first bolt 19, the fastening or disassembly can be achieved, which improves the flexibility and maintainability of the device and facilitates the staff to replace the infrared transmitter 11 and the infrared receiver 12 as needed. By starting the second hydraulic push rod 20, the support plate 10 can be moved forward and backward for adjustment, and then the position of the infrared transmitter 11 and the infrared receiver 12 can be adjusted, so that the detection method can adapt to the first roller 4 of different diameters, thereby improving the scope of application and flexibility of the device.

[0038] like Figure 1 , Figure 2 and Figure 4-Figure 7 As shown, two slide grooves 21 are provided on the top surface of the base 2, and sliders 22 are respectively fixed on the bottom surfaces of the two support plates 10. The two sliders 22 are respectively slidably arranged in the two slide grooves 21. A mounting groove 23 is provided on the right side of the outer wall of the base 2. An alarm 24 is detachably arranged inside the mounting groove 23. The alarm 24 is electrically connected to the DCS controller. A first magnet 25 is fixed inside the mounting groove 23, and a second magnet 26 is fixed on one side of the alarm 24. The second magnet 26 is magnetically attracted to the first magnet 25. Two second threaded grooves 27 are provided on the inner bottom surface of the base 2. Connecting plates 28 are respectively fixed on the front and rear sides of the first hydraulic push rod 13. Second threaded holes 29 are respectively provided on the top surfaces of the two connecting plates 28. Second bolts 30 are respectively threadedly connected in the two second threaded holes 29, and the threaded ends of the two second bolts 30 are respectively threadedly connected to the inner threads of the two second threaded grooves 27.

[0039] In use, the bottom surface of the support plate 10 is fixed with a slider 22, which is slidably arranged in the slide groove 21 on the top surface of the base 2, ensuring the stability and accuracy of the support plate 10 during movement, preventing deviation and shaking, and improving the stability and reliability of the device. When the DCS controller receives a fault signal, it will immediately trigger the alarm 24 to send out a warning sound and light signal, which can quickly attract the attention of the staff and take measures to deal with the fault in time; the first magnet 25 and the second magnet 26 facilitate the staff to quickly disassemble and assemble the alarm 24, thereby improving the flexibility and maintainability of the device. The first hydraulic push rod 13 is connected to the inner bottom surface of the base 2 through the connecting plate 28 and the second bolt 30. The staff can easily disassemble and replace the first hydraulic push rod 13 by rotating the second bolt 30, thereby improving the maintainability and flexibility of the device, and facilitating the staff to repair or replace the first hydraulic push rod 13 as needed, thereby reducing the maintenance cost and the risk of production interruption.

[0040] The present invention also provides a detection method for a belt roller device for fracture detection, comprising the following steps:

[0041] S1: The staff first installs the infrared transmitter 11 and the infrared receiver 12 along the non-contact surface of the first roller 4, respectively on the left and right sides of the first roller 4, and then starts the second hydraulic push rod 20 to enable the support plate 10 to move forward and backward to adjust the positions of the infrared transmitter 11 and the infrared receiver 12;

[0042] S2: During operation, the staff starts the driving motor 9 to rotate the rotating shaft 5 and the first roller 4, thereby driving the belt body 8 and the second roller 7 to rotate. At the same time, the infrared transmitter 11 and the infrared receiver 12 start to work to detect the cross-sectional state of the first roller 4 in real time. When the first roller 4 is in a normal state, the infrared receiver 12 can receive the infrared signal from the infrared transmitter 11. When the first roller 4 breaks, the broken part will be displaced due to the compression of the belt body 8, blocking the infrared beam, and the infrared receiver 12 cannot receive the infrared signal. When the infrared receiver 12 cannot receive the infrared signal, it will immediately send a status signal to the DCS controller. After judgment, the DCS controller will issue a belt conveyor interlocking stop command to stop the driving motor 9.

[0043] S3: When the DCS controller receives the status signal from the infrared receiver 12, it immediately starts the first hydraulic push rod 13, and the telescopic rod of the first hydraulic push rod 13 extends to push the U-shaped plate 14 upward until it contacts the rotating shaft 5 on the right side;
