[0029] The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0030] A mine conveyor belt breakage monitoring device, the structure of which can be schematically shown by Figures 1 - 5 In this embodiment, the mine conveyor belt breakage monitoring device includes: a bearing assembly, a cleaning assembly, and a monitoring assembly. The bearing assembly is used to realize the assembly between the device and the conveyor belt 9 and provide an installation basis for other components in the device. The cleaning assembly is used to clean the conveyor belt 9 to remove the dust and debris attached to the conveyor belt 9. The monitoring assembly is used to collect images of the conveyor belt 9 so that the upper controller can identify and analyze the images to determine whether there are cracks and notches on the conveyor belt 9, thereby warning of potential belt breakage risks.

[0031] Specifically, as Figures 1 - 3As shown in the figure, the bearing assembly includes a connecting seat 1 and a bearing seat 2. The bearing seat 2 is arranged on the connecting seat 1 with adjustable position, and an assembly notch for accommodating the cleaning assembly is provided on the bearing seat 2. The monitoring assembly includes a connecting plate 5 and an image collector 6. An installation cantilever 51 is provided on the side wall of the connecting plate 5. The image collector 6 for collecting the image of the conveyor belt 9 is arranged on the installation cantilever 51, and the image collector 6 is electrically connected to an upper controller (not shown in the figure) through a data line. When assembling this device and the conveyor belt 9, the staff can detachably arrange the connecting seat 1 on the frame of the conveyor belt 9 through bolts, and then detachably install the connecting plate 5 on the top of the bearing seat 2 through bolts. Subsequently, through the position adjustment of the bearing seat 2, the cleaning assembly and the monitoring assembly are located above the edge part of the conveyor belt 9.

[0032] During the actual working process, the conveyor belt 9 performs the material transportation work, which will cause the conveyor belt 9 to bear stress loads. If there are small cracks or notches at the edge of the conveyor belt 9, the action of the stress load will gradually enlarge the small cracks or notches. Over time, it will lead to a belt break accident of the conveyor belt 9. The traditional belt break monitor is usually set at the end of the conveyor belt 9, and its main monitoring position is the central area of the conveyor belt 9. It cannot detect small cracks in the edge part in time, so it cannot give an early warning of potential belt break risks. The belt break monitoring device for mine conveyor belts provided in this embodiment can, through the position adjustment of the bearing seat 2, make the cleaning assembly and the monitoring assembly located at the edge part of the conveyor belt 9, so as to easily detect the damage at the edge of the conveyor belt 9, thereby warning of potential belt break risks and reminding the staff to repair or replace the conveyor belt 9 in time.

[0033] It should be noted that the image collector 6 described in this embodiment can be a common industrial camera. When in use, the image collector 6 can take images of the conveyor belt 9 and send the images to the inside of the upper controller (such as a processor with an image recognition algorithm built in) through a data line. Subsequently, the upper controller will identify and analyze the images to judge whether there are small cracks or notches on the conveyor belt 9, and give an early warning to the staff when there are small cracks or notches on the conveyor belt 9, reminding the staff to repair or replace the conveyor belt 9 in time. Since the working principles and specific structures of the image collector 6 and the upper controller are well known to the public, those skilled in the art can correctly install and use the above devices according to the inspiration of the prior art, and the above content does not belong to the inventive content of this application, so it will not be elaborated in this application.

[0034] Optionally, in order to realize the position adjustment function of the bearing seat 2, the present embodiment may be provided with a positioning hole 11 on the connecting seat 1, and a positioning bolt 12 is provided inside the positioning hole 11. Accordingly, an oblong hole 23 for accommodating the positioning bolt 12 may be provided on the bearing seat 2, and the length direction of the oblong hole 23 should be perpendicular to the material conveying direction of the conveyor belt 9. After the connecting seat 1 is installed, the staff can loosen the positioning bolt 12 to facilitate the bearing seat 2 to slide along the length direction of the oblong hole 23, thereby adjusting the position of the cleaning component and the monitoring component relative to the conveyor belt 9, ensuring that the cleaning component and the monitoring component move to the edge area of the conveyor belt 9, and then tighten the positioning bolt 12 to limit the bearing seat 2 to prevent the bearing seat 2 from moving abnormally during use.

[0035] Since the materials transported by the mining conveyor belt are mostly mineral products, a large amount of dust and debris usually adheres to the top surface of the conveyor belt 9. In order to prevent dust and debris from blocking the small cracks on the conveyor belt 9, such as Figure 4 As shown, the cleaning assembly in this embodiment includes a mounting seat 3 and a cleaning roller brush 4. Specifically, the mounting seat 3 should be arranged inside the assembly cutout, and the cleaning roller brush 4 can be rotatably arranged on the side wall of the mounting seat 3. After the assembly between the device and the conveyor belt 9 is completed, the axial direction of the cleaning roller brush 4 should be perpendicular to the material conveying direction of the conveyor belt 9, and the side wall of the cleaning roller brush 4 should be in contact with the top surface of the conveyor belt 9. When the conveyor belt 9 starts to convey materials, the cleaning roller brush 4 will clean the edge of the top surface of the conveyor belt 9, thereby removing dust and debris attached to the conveyor belt 9, avoiding small cracks from being blocked, and thus improving the early warning accuracy of the device.

[0036] Optionally, in order to ensure a good cleaning effect between the cleaning roller brush 4 and the conveyor belt 9, the device may be provided with a guide rod 22 whose axial direction is perpendicular to the axial direction of the cleaning roller brush 4 inside the assembly cutout. Accordingly, the mounting seat 3 is provided with a guide hole 31 for accommodating the guide rod 22, and a spring 71 is sleeved on the guide rod 22, and the spring 71 is located above the mounting seat 3. Since the spring 71 is provided above the mounting seat 3, and the cooperation between the guide rod 22 and the guide hole 31 enables the mounting seat 3 to have the ability to slide along the guide rod 22, the staff can sleeve the spring 71 on the guide rod 22 in a compressed state, and apply downward pressure to the mounting seat 3 by means of the elastic force generated by the compression of the spring 71. At this time, a good fitting effect will be obtained between the side wall of the cleaning roller brush 4 and the conveyor belt 9, so that it is convenient for the cleaning roller brush 4 to remove the attachments on the conveyor belt 9.

[0037] In addition, to facilitate the adjustment of the elastic force inside the spring 71 by the staff, the guide rod 22 can be set as a threaded rod, and an adjusting nut 72 should also be provided on the guide rod 22, and the adjusting nut 72 is located above the spring 71. Before use, the staff can change the position of the adjusting nut 72 on the guide rod 22 according to the actual situation, so as to adjust the compression degree of the spring 71, and further make the spring 71 have different elastic forces, which is convenient to meet the cleaning requirements of different conveyor belts 9.

[0038] As an alternative implementation of this embodiment, to improve the assembly convenience of the device, an operating rod 32 can also be provided on the side wall of the mounting seat 3 away from the cleaning roller brush 4. When assembling the device with the conveyor belt 9, the staff can pull up the mounting seat 3 through the operating rod 32, so as to lift the height of the cleaning roller brush 4 during the installation process, and facilitate the contact between the side wall of the cleaning roller brush 4 and the top surface of the conveyor belt 9.

[0039] During the actual use process, the visibility of small cracks on the edge of the conveyor belt 9 is relatively poor, so it is easy to miss them during image recognition. To improve the visibility of small cracks, the bearing assembly described in this embodiment can further include a guide roller 21. As Figure 4 and Figure 5 shown, the guide roller 21 is rotatably arranged on the bearing seat 2, the guide roller 21 is located on the side of the mounting cantilever 51 away from the cleaning roller brush 4, the axis direction of the guide roller 21 is parallel to the axis direction of the cleaning roller brush 4, and the distance from the guide roller 21 to the top of the bearing seat 2 is equal to the distance from the cleaning roller brush 4 to the top of the bearing seat 2. After the assembly between the device and the conveyor belt 9 is completed, the side wall of the guide roller 21 will be in contact with the bottom surface of the conveyor belt 9. Since the distances from the guide roller 21 and the cleaning roller brush 4 to the top of the bearing seat 2 are equal, the conveyor belt 9 will undergo slight bending deformation between the cleaning roller brush 4 and the guide roller 21. The bending deformation of the conveyor belt 9 can expand small cracks, improve the visibility of small cracks in the image, and thus improve the early warning ability of the device.

[0040] Optionally, to facilitate the image collector 6 to collect the image of the edge of the conveyor belt after the crack is enlarged, an installation section can be provided on the side wall of the mounting cantilever 51 facing the guide roller 21, and the image collector 6 is arranged on the installation section, so as to facilitate the image collector 6 to obtain a good image shooting position.

[0041] As another alternative implementation of this embodiment, to prevent the conveyed materials on the conveyor belt 9 from affecting the working effect of the device, the mine conveyor belt 9 belt break monitoring device can further include a baffle plate. As Figure 2As shown in the figure, the baffle plate is detachably arranged at the end of the mounting cantilever 51 through bolts, and the baffle plate includes a feeding inclined surface 81, a baffle plane 82 and a discharging inclined surface 83 which are sequentially connected. When the materials on the conveyor belt 9 pass through the area where the device is located, the cooperation of the feeding inclined surface 81, the baffle plane 82 and the discharging inclined surface 83 can guide the materials, so as to prevent the materials from entering below the cleaning component and the monitoring component, and ensure good monitoring effect of the device.

[0042] The effects of the above scheme are described below:

[0043] This embodiment provides a mine conveyor belt breakage monitoring device, which can remove the attachments on the conveyor belt through the cleaning roller brush, facilitate the discovery of small cracks existing at the edge, and thus timely issue a warning of the breakage accident. Secondly, the device can make the conveyor belt bend and deform through the cooperation of the guide roller and the cleaning roller brush, so as to improve the visibility of small cracks and enhance the warning ability of the device. In addition, the device can also adjust the elastic force of the spring according to the actual situation to enable the cleaning roller brush to obtain a good cleaning effect.

[0044] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
