Description

Technical Field

[0001] This invention relates to the field of belt anomaly detection technology, specifically to a device and system for detecting the condition of belt working surfaces. Background Technology

[0002] Belt conveyors are machines that use the endless motion of belts to transport materials. They have advantages such as long transport distance, large transport capacity, low working resistance, easy installation, low power consumption, and low wear, and are widely used in the metal smelting industry.

[0003] During operation, if the material being transported contains sharp points or is unevenly distributed on the belt, the former will cause scratches on the belt, while the latter will result in uneven stress on the working surface of the belt. Since the belt is constantly running, this will aggravate the scratches or uneven stress, leading to cracks or even breakage of the belt. This results in significant belt damage, very slow recovery, and greatly affects production, causing huge economic losses.

[0004] Current domestic and international belt inspection technologies include impact testing, abnormal stress detection of idlers, ultrasonic testing, piezoresistive testing, and sensor embedded testing. However, these methods have limitations in terms of accuracy for belt tear detection, and are relatively complex to install and maintain, resulting in high costs.

[0005] Therefore, this application proposes a device for detecting the condition of a conveyor belt working surface to solve the above-mentioned technical problems. The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0006] The main objective of this invention is to provide a device and system for detecting the condition of a conveyor belt working surface, which can quickly detect whether there are cracks or breaks in the conveyor belt and can track the specific location of the cracks or breaks on the conveyor belt in real time with high speed and accuracy.

[0007] The present invention solves the above-mentioned technical problems by adopting the following technical solutions:

[0008] A device for detecting the condition of a conveyor belt working face, comprising:

[0009] A support frame for mounting a conveyor belt, wherein a belt drive component for driving the conveyor belt is mounted on the support frame via a mounting plate;

[0010] An image-capturing device, mounted on a mounting plate, is used to align and illuminate the conveyor belt located above.

[0011] The photosensitive elements are configured in multiple groups and are mounted on the support frame separately by multiple groups of mounting brackets, and the photosensitive elements are distributed between adjacent idlers of the conveyor belt.

[0012] A light-emitting device is mounted on a mounting plate to continuously illuminate the conveyor belt.

[0013] Preferably, the belt drive includes multiple sets of connecting idlers evenly spaced in the middle of the conveyor belt, two sets of external tensioning idlers at both ends of the conveyor belt for tensioning and supporting the conveyor belt, a synchronous drive unit mounted on a support frame for driving the multiple sets of connecting idlers to rotate synchronously, a first synchronous pulley mounted on the support frame and connected to the synchronous drive unit for driving the external tensioning idlers to rotate and engaging with the connecting idlers to drive the conveyor belt to rotate, and an idler drive unit mounted on the support frame for coaxially driving the synchronous drive unit and the first synchronous pulley to rotate.

[0014] Preferably, the synchronous drive component includes multiple sets of connecting gears rotatably mounted on the support frame and a toothed chain disposed outside the connecting gears for meshing and driving the multiple sets of connecting gears to rotate synchronously.

[0015] The multiple sets of connecting gears located in the middle of the toothed chain are used to coaxially drive the connecting roller to rotate during rotation.

[0016] The two sets of connecting gears located at both ends of the toothed chain are used to coaxially drive the first synchronous pulley during rotation.

[0017] Preferably, the idler roller drive includes a drive motor located on the mounting plate and a second synchronous pulley disposed on the drive end of the drive motor for coaxially driving the synchronous drive and the first synchronous pulley to rotate.

[0018] A system for detecting the condition of a conveyor belt working face includes an external server equipped with an operating terminal and any of the aforementioned devices for detecting the condition of a conveyor belt working face. The server includes a memory and a processor. The memory stores a computer program, and the processor runs the program stored in the memory. The server is used to receive data signals emitted by a photosensitive element and an image-capturing device, and to perform data storage and model building analysis operations.

[0019] Preferably, the server internally includes:

[0020] The model building module is used to build a three-dimensional model of the conveyor belt based on the data signals emitted by the photosensitive element and the imaging device during one revolution of the conveyor belt.

[0021] The belt operation monitoring module is used to monitor the drive operation status of the conveyor belt in real time.

[0022] The time axis control module is used to adjust the state of the three-dimensional model of the conveyor belt according to the specific time of belt operation;

[0023] The image acquisition and analysis module is used to select the image of the conveyor belt at the current position of the image acquisition device after the time axis control module has adjusted the time.

[0024] Preferably, the specific steps for establishing the three-dimensional model of the conveyor belt include:

[0025] S100. Select a fixed position at the bottom of the device to install the imaging device, and start the conveyor belt to carry out normal material transportation;

[0026] S200. During one revolution of the conveyor belt, a photograph of the conveyor belt surface is normally captured by the imaging device and the photograph is sent to the model building module;

[0027] S300. Calculate the time it takes for the conveyor belt to rotate one revolution, create a time axis in the model building module, and combine the conveyor belt surface photos to create a 3D model of the belt according to the photo data transmitted at different times on the time axis in the model building module.

[0028] Preferably, due to the differences in the working surface areas of the conveyor belt, the specific method for creating a 3D model of the belt within the model creation module is as follows:

[0029] S1. When the conveyor belt is not running, align the imaging device with the conveyor belt to acquire images; this is marked as the initial position.

[0030] S2. After the conveyor belt starts running, calculate the running speed of the conveyor belt and the part on the conveyor belt where the image acquisition device re-acquires the image that coincides with the initial position. The image data obtained during this period is the working surface image data required for the conveyor belt to run one revolution. Then, by combining the belt length and width with the running time, the three-dimensional model of the belt can be obtained.

[0031] Preferably, when the conveyor belt is running and transporting materials normally, the lighting equipment is continuously turned on, and a photosensitive element is used to determine whether there are cracks or breaks in the conveyor belt. If there are, the location information of the crack or break is obtained by combining the three-dimensional model of the belt and tracked as the conveyor belt runs along the time axis.

[0032] a2. After the belt conveying task is completed, the established three-dimensional model of the belt is used to locate the cracks or breaks in the conveyor belt. The imaging device is moved and installed at the cracks or breaks in the conveyor belt to collect images and obtain tear data of the working surface of the conveyor belt.

[0033] This invention provides a device for detecting the condition of a conveyor belt working surface. Compared with the prior art, the advantages of this invention are as follows:

[0034] 1. During conveyor belt operation, the present invention continuously operates the lighting equipment and uses photosensitive elements to determine whether there are cracks or breaks in the conveyor belt. If a crack or break is found, the location information of the crack or break is obtained by combining the three-dimensional model of the belt and tracked as the conveyor belt moves along the time axis. This allows for the immediate detection of cracks or breaks in the conveyor belt and timely cessation of its operation, preventing significant economic losses caused by cracks or breaks affecting the operation of the entire conveyor belt. Furthermore, the device of the present invention can identify the location of cracks or breaks at the first moment they occur, greatly facilitating maintenance by personnel.

[0035] 2. This invention enables real-time monitoring of the working surface of the conveyor belt by setting up an imaging device to quickly acquire images of the conveyor belt and establish a three-dimensional model of the belt. This solves the problem of traditional belt inspection being labor-intensive and time-consuming, enhances the timeliness of belt repair for maintenance personnel and on-site staff, increases the service life of the belt, and ultimately reduces the risk of production reduction caused by belt downtime.

[0036] 3. This invention establishes a three-dimensional model of the conveyor belt by acquiring images of the belt's working surface, which facilitates the detection and analysis of the belt's usage. It can not only evaluate the torn parts based on the tear results of the three-dimensional model of the belt and provide belt maintenance suggestions, but also promptly transmit the information to maintenance personnel and on-site workers, ensuring the normal operation of the belt in real time, extending the overall service life of the conveyor belt, and saving resources.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] In the first embodiment, see details below. Figures 1 to 3 .

[0048] like Figure 1 and Figure 2 As shown, the present invention provides a device for detecting the condition of a conveyor belt working face, comprising:

[0049] Support frame 1 is used to install conveyor belt 3. Belt drive component 2 for driving the conveyor belt 3 is installed on support frame 1 via mounting plate 11.

[0050] Image acquisition device 4, mounted on mounting plate 11, is used to align and illuminate the conveyor belt 3 located above;

[0051] The photosensitive element 5 is configured as multiple groups and is installed on the support frame 1 by multiple groups of mounting brackets 12, and the photosensitive element 5 is distributed between adjacent idlers of the conveyor belt 3.

[0052] The light-emitting device 6 is mounted on the mounting plate 11 for continuous illumination of the conveyor belt 3.

[0053] When the conveyor belt 3 is in operation, the lighting equipment 6 is continuously turned on, and the photosensitive element 5 can quickly determine whether there are cracks or breaks in the conveyor belt 3, thereby avoiding potential safety risks.

[0054] Specifically, with the help of the photosensitive element 5, the real-time status of the conveyor belt 3 can be detected quickly and accurately. If a crack or break is found in the conveyor belt 3, the system will immediately issue an alarm to notify the staff to carry out repairs, thereby ensuring the safety and stability of the belt in transporting materials.

[0055] It should be noted that the image capturing device 4, photosensitive element 5 and light-emitting illumination device 6 mentioned above are all existing technologies. The image capturing device 4 can be directly used with the existing camera structure, the photosensitive element 5 can be a photosensitive sensor in the existing technology, and the light-emitting illumination device 6 can be an existing LED light-emitting device.

[0056] In addition, the light-emitting device 6 can also be used as a supporting device to provide the necessary brightness when the image-capturing device 4 captures an image.

[0057] The belt drive component 2 includes multiple sets of connecting idlers 21 evenly spaced in the middle of the conveyor belt 3, two sets of external tensioning idlers 22 located at both ends of the conveyor belt 3 for tensioning and supporting the conveyor belt 3, a synchronous drive component 23 mounted on the support frame 1 for driving the multiple sets of connecting idlers 21 to rotate synchronously, a first synchronous pulley 24 mounted on the support frame 1 and connected to the synchronous drive component 23 for driving the external tensioning idlers 22 to rotate and engaging with the connecting idlers 21 to drive the conveyor belt 3 to rotate, and an idler drive component 25 mounted on the support frame 1 for coaxially driving the synchronous drive component 23 and the first synchronous pulley 24 to rotate.

[0058] Among them, the connecting roller 21 is used to support the upper surface of the conveyor belt 3 to ensure the normal support and operation of the material on the conveyor belt 3, and the two sets of external tensioning rollers 22 are used to ensure the normal operation of the conveyor belt 3 while there is space between the lower surface and the connecting roller 21 for placing the photosensitive element 5.

[0059] In addition, the synchronous drive component 23 includes multiple sets of connecting gears 231 rotatably mounted on the support frame 1 and a toothed chain 232 disposed outside the connecting gears 231 for meshing and driving the multiple sets of connecting gears 231 to rotate synchronously.

[0060] The multiple sets of connecting gears 231 located in the middle of the toothed chain 232 are used to coaxially drive the connecting roller 21 to rotate during rotation.

[0061] The two sets of connecting gears 231 located at both ends of the toothed chain 232 are used to coaxially drive the first synchronous pulley 24 to rotate during rotation.

[0062] Therefore, when the two sets of external tensioning rollers 22 and the multiple sets of connecting rollers 21 operate synchronously, they can drive the conveyor belt 3 to operate normally. At the same time, they can ensure that the photosensitive element 5 is evenly distributed on the inner side of the conveyor belt 3 so as to ensure that it can normally sense whether there are cracks or breaks on the working surface of the belt.

[0063] The idler roller drive unit 25 includes a drive motor 252 located on the mounting plate 11 and a second synchronous pulley 251 disposed on the drive end of the drive motor 252 for coaxially driving the synchronous drive unit 23 to operate with the first synchronous pulley 24.

[0064] During operation, the drive motor 252 controls the first synchronous pulley 24 and the toothed chain 232 to run simultaneously through the second synchronous pulley 251, thereby driving the conveyor belt 3 to run for material transportation through the outer tension roller 22 and the connecting roller 21.

[0065] It should be noted that the drive motor 252 here can be a servo motor from the existing technology.

[0066] Based on the above embodiments, a second embodiment is proposed, for details please refer to Figure 4 , Figure 5 and Figure 6 .

[0067] A system for detecting the condition of a conveyor belt working surface includes an external server 7 equipped with an operating terminal and the aforementioned device for detecting the condition of a conveyor belt working surface. The server 7 includes a memory and a processor. The memory stores a computer program, and the processor runs the program stored in the memory. The server 7 is used to receive data signals emitted by the photosensitive element 5 and the imaging device 4 and to perform data storage and model building analysis operations.

[0068] Server 7 contains the following:

[0069] The model building module is used to build a three-dimensional model of the conveyor belt 3 based on the data signals emitted by the photosensitive element 5 and the image acquisition device 4 after one revolution of the conveyor belt 3.

[0070] The belt operation monitoring module is used to monitor the drive operation status of the conveyor belt 3 in real time;

[0071] The time axis control module is used to adjust the state of the three-dimensional model of the conveyor belt 3 according to the specific time of belt operation;

[0072] The image acquisition and analysis module is used to select the image of the conveyor belt 3 at the current position of the image acquisition device 4 after the time axis control module adjusts the time.

[0073] At this time, by setting up the imaging device 4 to quickly acquire images of the working surface of the conveyor belt 3 and establish a three-dimensional model of the belt, it is possible to realize real-time monitoring of the working surface condition of the belt, solve the problem of traditional belt inspection being labor-intensive and time-consuming, enhance the timeliness of belt repair by maintenance personnel and on-site staff, increase the service life of the belt, and finally reduce the risk of production reduction caused by belt downtime.

[0074] It should be noted here that the computer program in the server 7 memory can use system algorithms with convolutional neural networks and repetitive neural networks trained by computer deep learning to assist in model building. Convolutional neural networks mimic the visual perception mechanism of biological organisms, have representation learning capabilities, can classify input information according to its hierarchical structure with translation invariance, and can perform supervised and unsupervised learning, with good robustness and generalization ability.

[0075] Furthermore, in this case, the server 7 can also be equipped with a belt model detection and analysis module, which includes belt tear analysis, belt life analysis, and belt working condition evaluation model, for real-time tracking of the belt working surface status.

[0076] Furthermore, the specific steps for establishing the three-dimensional model of conveyor belt 3 include:

[0077] S100. Select a fixed position at the bottom of the device to install the imaging device 4, and start the conveyor belt 3 to carry out normal material transportation;

[0078] S200. During one rotation of the conveyor belt 3, the surface of the conveyor belt 3 is normally photographed by the imaging device 4 and the photograph is sent to the model building module;

[0079] S300. Calculate the time it takes for the conveyor belt 3 to rotate one revolution. Create a time axis in the model creation module and combine it with the surface photos of the conveyor belt 3 to create a three-dimensional model of the belt according to the photo data transmitted at different times on the time axis in the model creation module.

[0080] Furthermore, due to the differences in the working surface of the conveyor belt 3, the specific method for creating the 3D model of the belt within the model creation module is as follows:

[0081] S1. When the conveyor belt 3 is not running, align the image acquisition device with the conveyor belt to acquire an image. This is marked as the initial position.

[0082] S2. After the conveyor belt 3 starts running, calculate the running speed of the conveyor belt 3 and the part on the conveyor belt 3 where the image acquisition device re-acquires the image that coincides with the initial position. The image data obtained during this period is the working surface image data required for the conveyor belt 3 to run one cycle. Then, by combining the belt length and width with the running time, the three-dimensional model of the belt can be obtained.

[0083] Furthermore, the methods for using the 3D model of the belt include:

[0084] a1. When the conveyor belt 3 is in operation and the material is being transported normally, the lighting equipment 6 is continuously turned on, and the photosensitive element 5 is used to determine whether there are cracks or breaks in the conveyor belt 3. If there are, the location information of the crack or break is obtained by combining the three-dimensional model of the belt and tracked as the conveyor belt 3 moves along the time axis.

[0085] a2. After the belt conveying task is completed, the cracks or breaks of the conveyor belt 3 are located using the established three-dimensional model of the belt. The imaging device 4 is moved and installed at the cracks or breaks of the conveyor belt 3 to collect images and obtain tear data of the working surface of the conveyor belt 3.

[0086] Further reference Figure 5 To determine the three-dimensional model of the belt, it is necessary to first draw a three-dimensional model of the belt and obtain and record relevant data. Then, draw the three-dimensional coordinate axis of the belt, with the belt head as the origin, determine the position of each idler roller of the belt, and number all the idlers.

[0087] At this time, when the system detects a crack on the working surface of the conveyor belt 3, it transmits the information and belt speed to the photosensitive element 5 to determine the nearest idler roller number, thereby determining the location of the belt crack.

[0088] In summary, during the operation of conveyor belt 3, the lighting equipment 6 is continuously turned on, and the photosensitive element 5 is used to determine whether there are cracks or breaks in conveyor belt 3. If a crack or break is found, the location information of the crack or break is obtained by combining the three-dimensional model of the belt and tracked as the conveyor belt 3 moves along the time axis. This allows for the immediate detection of cracks or breaks in conveyor belt 3 and timely cessation of its operation, preventing the crack or break from affecting the operation of the entire conveyor belt 3 and causing huge economic losses. Furthermore, the device of this invention can identify the location of cracks or breaks at the first moment they occur, greatly facilitating maintenance by the staff.

[0089] Furthermore, during the 3D model building process, when the belt 3D model is built based on digital image processing using a convolutional neural network, the convolutional neural network can continuously deepen the training model through intelligent algorithms.

[0090] At this point, the 3D model of the belt first performs image enhancement, image segmentation, and image feature extraction on the working surface image of the belt to obtain data information on the tear at the working surface of the belt, such as the length and depth of the tear. Then, the data is analyzed and judged by the mathematical model of belt detection to obtain the belt life prediction result and the tear analysis result of the working surface of the belt.

[0091] Therefore, by acquiring images of the belt's working surface and establishing a three-dimensional model of the belt, it is possible to conveniently detect and analyze the belt's usage. Not only can the tearing results of the three-dimensional model of the belt be used to evaluate the torn parts and provide belt maintenance suggestions, but the information can also be promptly transmitted to maintenance personnel and on-site staff, ensuring the normal operation of the belt in real time, extending the overall service life of the conveyor belt 3, and saving resources.

If the specific posture changes, the directional indication will also change accordingly.
