[0002] In the process of coal transportation, the belt conveyor undertakes the important task of transferring coal from underground to the ground or other designated locations. However, due to the limit of the tension that the belt can withstand, the belt may break when encountering extreme conditions such as high speed and high tension. The occurrence of belt breakage accidents will not only cause the loss of the equipment itself, but also may cause a series of safety problems. For example, belt breakage may cause heavy objects to fall, posing a threat to the life safety of on-site workers. Therefore, a belt breakage protection device is needed to improve production safety and personnel safety.

[0032] When the support frame 2 and the tearing AI detection device 4 are installed on the transport frame 1, both sides of the support frame 2 are engaged with the transport frame 1, and then the first installation frame 15 is engaged with the support plate 3, and then the servo motor 5 drives the rotating disk 9 to rotate, and the moving rod 8 moves along the arc groove 11 on the rotating disk 9, which can drive the two moving plates 6 and the two moving frames 7 to move outward, and the moving plates 6 and the moving frames 7 can be respectively engaged in the second engaging groove 16 and the first engaging groove 14 at the same time, so that the support frame 2 and the tearing AI detection device 4 can be installed and fixed at the same time, and the tearing AI detection device 4 and the support frame 2 can be quickly installed, thereby improving the installation efficiency of the device;

[0033] When the support frame 2 and the tearing AI detection device 4 are disassembled, the servo motor 5 drives the rotating disk 9 to rotate, and the moving rod 8 moves in the arc groove 11, so that the two moving plates 6 and the two moving frames 7 can be driven to move relative to each other, so that the moving plates 6 and the moving frames 7 are respectively moved out from the second engaging groove 16 and the first engaging groove 14, and then the support frame 2 and the tearing AI detection device 4 can be disassembled from the transport frame 1, so that the device can be inspected and used, and the operation can be completed quickly, reducing downtime and improving production efficiency.

[0034] Clamping structures are provided at both ends of the support frame 2, and two clamping blocks 13 are provided at one end of the mobile frame 7 away from the mobile rod 8. First clamping grooves 14 for the clamping blocks 13 to engage are provided on both sides of the support frame 2. The clamping mechanism includes a clamping plate 17, and the clamping plate 17 is connected to the support frame 2 through a connecting component. One end of the clamping plate 17 is connected to the support frame 2 through an adjusting component. The connecting component includes a first connecting block 18 and two second connecting blocks 19. The first connecting block 18 is fixedly connected to the support frame 2, and the two second connecting blocks 19 are fixedly connected to the clamping plate 17.

[0035] Specifically, the adjustment component includes a driving motor 20, a servo electric cylinder 21, a return spring 22, a first connecting rod 23 and a second connecting rod 24. The driving motor 20 is installed on the support frame 2, and the output end of the servo motor 5 is connected to the servo electric cylinder 21 through a rotating component. The output end of the servo electric cylinder 21 is connected to the first connecting rod 23, and the second connecting rod 24 is connected to one end of the clamping plate 17.

The output end of the drive motor 20 is connected to the rotating disk 26.

[0037] When the tearing AI detection device 4 detects that the belt is torn, the driving end of the coal mine transport belt can be controlled to stop. When the tearing AI detection device 4 detects that the belt is broken, the driving motor 20 drives the rotating disk 26 to rotate. When the rotating disk 26 rotates, the limiting ring 27 rotates in the limiting groove 28, so that the rotating disk 9 can be limited, and the servo electric cylinder 21 can be driven to rotate, and at the same time, the first connecting rod 23 is driven to rotate, so that the meshing triangular blocks 25 are separated. At this time, the reset spring 22 releases the elastic force, which can push one end of the clamping plate 17 to move, so that the rubber layer 32 on the second mounting frame 31 is in contact with the belt, and the belt can be clamped. When the belt is torn and broken, the belt can be clamped quickly, which can prevent the belt and materials from continuing to slide down, protect the safety of personnel, and avoid causing greater injuries and losses;

[0038] When adjusting and reusing the device, the servo electric cylinder 21 drives the first connecting rod 23 to move. When it moves to a certain position, the driving motor 20 drives the rotating disk 26 to rotate, so that the triangular blocks 25 engage with each other. Then the servo electric cylinder 21 drives the first connecting rod 23 to move, which can drive one end of the clamping plate 17 to move and open, so that the device can be used again.

[0039] Furthermore, the support frame 2 and the clamping plate 17 are both provided with a mounting block 29, and a second mounting frame 31 is installed on the mounting block 29 by means of mounting bolts 30.

The setting of the mounting bolts 30 facilitates the installation and disassembly of the second mounting frame 31. When the rubber layer 32 is damaged, the rubber layer 32 can be disassembled and replaced.

[0040] On the basis of the above embodiment, a connecting frame 33 is fixedly provided on one side of the support frame 2, and a support rod 34 is provided between the connecting frame 33 and one end of the support frame 2.

[0044] S1. Install the support frame and the tearing AI detection device at the same time: snap the support frame 2 onto the transport frame 1, snap the first installation frame 15 onto the support frame 2, then the servo motor 5 drives the rotating disk 9 to rotate. Since the rotating disk 9 is provided with an arc groove 11 for the moving rod 8 to move, the two moving plates 6 and the two moving frames 7 can be driven to move relative to each other, so that the moving plates 6 and the moving frames 7 are snapped into the second snap groove 16 and the first snap groove 14 respectively, and the support frame 2 and the tearing AI detection device 4 can be installed and fixed;

[0045] S2. When the belt is clamped: the tearing AI detection device 4 detects that the belt is torn or broken, the driving motor 20 drives the rotating disk 26 to rotate, which can drive the servo electric cylinder 21 to rotate, and at the same time drives the first connecting rod 23 to rotate, so that the meshing triangular blocks 25 are separated. At this time, the return spring 22 releases the elastic force, which can push one end of the clamping plate 17 to move, so that the rubber layer 32 on the second mounting frame 31 is in contact with the belt, and the belt can be clamped;

[0046] S3. When disassembling the support frame or the tearing AI detection equipment: the servo motor 5 drives the rotating disk 9 to rotate, and the moving rod 8 moves in the arc groove 11, so it can drive the two moving plates 6 and the two moving frames 7 to move relative to each other, so that the moving plates 6 and the moving frames 7 are respectively moved out from the second engaging groove 16 and the first engaging groove 14, and then the support frame 2 and the tearing AI detection equipment 4 can be disassembled from the transport frame 1.

[0047] It should be noted that the specific models and specifications of the tearing AI detection equipment 4, servo electric cylinder 21, servo motor 5 and drive motor 20 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field.
