Description

Technical Field

[0001] This invention relates to the field of coal mine transportation technology, specifically to a belt breakage protection device and its usage method. Background Technology

[0002] In coal mine transportation, belt conveyors play a crucial role in transferring coal from underground to the surface or other designated locations. However, because belts have a limit to their tensile strength, they may break under extreme conditions such as high speed and high tension. Belt breakage accidents not only lead to equipment damage but can also trigger a series of safety problems. For example, a broken belt may cause heavy objects to fall, threatening the lives of on-site workers. Therefore, belt breakage protection devices are needed to improve production safety and personnel safety.

[0003] Existing belt breakage protection devices are mainly fixed to the conveyor frame with bolts. When these devices are damaged and need replacement, the replacement efficiency is low, thus affecting coal conveying efficiency. During regular inspections and maintenance, it is necessary to disassemble bolts, nuts, and other fasteners to check for wear and corrosion at the connection points. This not only increases the maintenance workload but may also damage the connection points. Therefore, we need to propose a belt breakage protection device and its usage method. Summary of the Invention

[0004] The purpose of this invention is to provide a belt breakage protection device and a method of use to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a belt breakage protection device, comprising a transport frame and a support frame, wherein a support plate is provided on the transport frame, and a tear AI detection device is connected to the support plate through a fixing structure, the fixing structure comprising a servo motor, two moving plates, two moving frames, two moving rods and a rotating disk, wherein an installation groove is provided on the support plate, the servo motor is installed in the installation groove, and the output end of the servo motor is connected to the rotating disk, wherein an arc-shaped groove is provided on the rotating disk, and the two moving rods are respectively connected at both ends to the moving plates and the moving frames, and the support plate is provided with a moving groove;

[0006] The support frame is provided with clamping structures at both ends, and the movable frame is provided with two locking blocks at the end away from the movable rod. The support frame is provided with first locking grooves on both sides for the locking blocks to engage.

[0007] Preferably, the tear AI detection device has a first mounting frame at its lower end, which engages with the support plate.

[0008] Preferably, the first mounting frame has second engaging slots on both sides, and the two movable plates engage in the second engaging slots.

[0009] Preferably, the clamping structure includes a clamping plate, which is connected to the support frame via a connecting assembly, and one end of the clamping plate is connected to the support frame via an adjusting assembly.

[0010] Preferably, the connecting assembly includes a first connecting block and two second connecting blocks. The first connecting block is fixedly connected to the support frame, and the two second connecting blocks are fixedly connected to the clamping plate. The first connecting block is rotatably connected between the two second connecting blocks.

[0011] Preferably, the adjustment assembly includes a drive motor, a servo cylinder, a return spring, a first connecting rod, and a second connecting rod. The drive motor is mounted on the support frame, and its output end is connected to the servo cylinder via a rotating assembly. The output end of the servo cylinder is connected to the first connecting rod, and the second connecting rod is connected to one end of the clamping plate. One end of the first connecting rod and the second connecting rod are provided with interlocking triangular blocks. The return spring is sleeved on the outside of the servo cylinder, and its two ends are respectively connected to the support frame and the clamping plate.

[0012] Preferably, the rotating assembly includes a rotating disk and a limiting ring. The support frame has a limiting groove for the limiting ring to rotate and connect. The limiting ring is fixedly connected to one side of the rotating disk. The servo electric cylinder is fixedly installed on the side of the rotating disk away from the limiting ring. The output end of the drive motor is connected to the rotating disk.

[0013] Preferably, both the support frame and the clamping plate are provided with mounting blocks, and a second mounting frame is mounted on the mounting block by mounting bolts, and the second mounting frame is provided with a rubber layer.

[0014] Preferably, a connecting frame is fixedly provided on one side of the support frame, and a support rod is provided at one end of the connecting frame and the support frame.

[0015] The method for using a belt breakage protection device includes the following steps:

[0016] S1. Simultaneously install the support frame and the tear AI detection equipment: snap the support frame onto the transport frame, snap the first mounting frame onto the support plate, and then the servo motor drives the rotating disk to rotate. Since the rotating disk has an arc-shaped groove for the moving rod to move, it can drive the two moving plates and the two moving frames to move relative to each other, so that the moving plates and the moving frames are respectively snapped into the second snap-fit ​​groove and the first snap-fit ​​groove, thus installing and fixing the support frame and the tear AI detection equipment.

[0017] S2. When clamping the belt: The tear AI detection device detects that the belt is torn or broken. The drive motor drives the rotating disk to rotate, which can drive the servo cylinder to rotate. At the same time, it drives the first connecting rod to rotate, causing the meshing triangular blocks to separate. At this time, the reset spring releases its elastic force, which can push one end of the clamping plate to move, so that the rubber layer on the second mounting frame contacts and connects with the belt, thus clamping the belt.

[0018] S3. When disassembling the support frame or the tear AI detection equipment: the servo motor drives the rotating disk to rotate, and the moving rod moves in the arc groove, so that the two moving plates and two moving frames can move relative to each other, so that the moving plates and moving frames can be moved out of the second locking groove and the first locking groove respectively. Then the support frame and the tear AI detection equipment can be disassembled from the transport frame.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention uses a tear AI detection device to detect whether a belt is torn, so that workers can repair the belt in a timely manner, improving the safety of the device. Furthermore, the fixed structure allows for quick installation of the tear AI detection device and support frame, improving installation efficiency and facilitating maintenance. This enables rapid operation, reduces downtime, and increases production efficiency.

[0021] 2. The present invention, through the setting of the clamping structure, can quickly clamp the belt when it is torn or broken, which can prevent the belt and materials from continuing to slide down, protect personnel safety, and avoid causing greater damage and loss.

[0028] 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 some embodiments of the present invention, and not all embodiments. 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.

[0029] Example 1:

[0030] Please see Figures 1-5 The present invention provides a technical solution: a belt breakage protection device, including a transport frame 1 and a support frame 2. The transport frame 1 is provided with a support plate 3. A tear AI detection device 4 is connected to the support plate 3 through a fixed structure. The fixed structure includes a servo motor 5, two moving plates 6, two moving frames 7, two moving rods 8 and a rotating disk 9. The support plate 3 is provided with an installation groove 10. The servo motor 5 is installed in the installation groove 10 and the output end of the servo motor 5 is connected to the rotating disk 9. The rotating disk 9 is provided with an arc-shaped groove 11. The two ends of the moving rods 8 are respectively connected to the moving plates 6 and the moving frames 7. The support plate 3 is provided with a moving groove 12.

[0031] Among them, the tear AI detection device 4 has a first mounting frame 15 at the lower end, which is engaged with the support plate 3. The first mounting frame 15 has a second engaging groove 16 on both sides, and the two moving plates 6 are engaged in the second engaging groove 16.

[0032] When the support frame 2 and the tear AI detection device 4 are installed on the transport frame 1, the two sides of the support frame 2 are engaged on the transport frame 1. Then, the first mounting frame 15 is engaged on the support plate 3. 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. The moving plates 6 and the moving frames 7 can be engaged in the second engagement groove 16 and the first engagement groove 14 respectively, so that the support frame 2 and the tear AI detection device 4 can be installed and fixed at the same time. The tear AI detection device 4 and the support frame 2 can be installed quickly, which improves the installation efficiency of the device.

[0033] When disassembling the support frame 2 and the tear AI detection device 4, the servo motor 5 drives the rotating disk 9 to rotate, and the moving rod 8 moves in the arc groove 11, which 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 removed from the second locking groove 16 and the first locking groove 14 respectively. Then the support frame 2 and the tear AI detection device 4 can be disassembled from the transport frame 1 for maintenance and use of the device. This allows for quick operation, reduces downtime, and improves production efficiency.

[0034] The support frame 2 has clamping structures at both ends. The movable frame 7 has two locking blocks 13 at the end away from the movable rod 8. The support frame 2 has first locking grooves 14 on both sides for the locking blocks 13 to engage. The clamping structure includes a clamping plate 17. The clamping plate 17 is connected to the support frame 2 through a connecting assembly. One end of the clamping plate 17 is connected to the support frame 2 through an adjusting assembly. The connecting assembly 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. The first connecting block 18 is rotatably connected between the two second connecting blocks 19.

[0035] Specifically, the adjustment assembly includes a drive motor 20, a servo cylinder 21, a return spring 22, a first connecting rod 23, and a second connecting rod 24. The drive motor 20 is mounted on the support frame 2, and the output end of the drive motor 20 is connected to the servo cylinder 21 through a rotating assembly. The output end of the servo cylinder 21 is connected to the first connecting rod 23. The second connecting rod 24 is connected to one end of the clamping plate 17. One end of the first connecting rod 23 and the second connecting rod 24 is provided with a triangular block 25 that meshes with each other. The return spring 22 is sleeved on the outside of the servo cylinder 21, and both ends of the return spring 22 are connected to the support frame 2 and the clamping plate 17, respectively.

[0036] The rotating assembly includes a rotating disk 26 and a limiting ring 27. The support frame 2 has a limiting groove 28 for the limiting ring 27 to rotate and connect. The limiting ring 27 is fixedly connected to one side of the rotating disk 26. The servo electric cylinder 21 is fixedly installed on the side of the rotating disk 26 away from the limiting ring 27. The output end of the drive motor 20 is connected to the rotating disk 26.

[0037] When the tear detection AI device 4 detects a tear in the belt, it can control the drive end of the coal mine conveyor belt to stop. When the tear detection AI device 4 detects a belt breakage, the drive 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, which can limit the rotating disk 9. This can drive the servo cylinder 21 to rotate, and at the same time drive the first connecting rod 23 to rotate, causing the meshing triangular block 25 to separate. At this time, the reset spring 22 releases its 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 contacts and connects with the belt, which can clamp the belt. This can quickly clamp the belt when it is torn or broken, which can prevent the belt and materials from continuing to slide down, protect personnel safety, and avoid greater damage and loss.

[0038] When adjusting the device for reuse, the servo cylinder 21 drives the first connecting rod 23 to move. When it moves to a certain position, the drive motor 20 drives the rotating disk 26 to rotate, so that the triangular blocks 25 mesh with each other. Then, the servo 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, both the support frame 2 and the clamping plate 17 are provided with mounting blocks 29. A second mounting frame 31 is mounted on the mounting block 29 by mounting bolts 30. The second mounting frame 31 is provided with a rubber layer 32. When the support frame 2 and the clamping plate 17 clamp the belt, the rubber layer 32 can increase the friction and facilitate the clamping of the belt. The mounting bolts 30 facilitate the installation and removal of the second mounting frame 31. When the rubber layer 32 is damaged, it can be removed and replaced.

[0040] Based on the above embodiments, a connecting frame 33 is fixedly provided on one side of the support frame 2, and a support rod 34 is provided at one end of the connecting frame 33 and the support frame 2. By setting the connecting frame 33 and the support rod 34, the support effect of the support frame 2 can be improved and the support strength of the support frame 2 can be increased.

[0041] Example 2:

[0042] The difference from Example 1 is that:

[0043] The belt breakage protection device and its usage method include the following steps:

[0044] S1. Simultaneously install the support frame and the tear AI detection equipment: snap the support frame 2 onto the transport frame 1, snap the first mounting frame 15 onto the support plate 3, and then drive the servo motor 5 to rotate the rotating disk 9. Since the rotating disk 9 has an arc groove 11 for the moving rod 8 to move, 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 snapped into the second snap groove 16 and the first snap groove 14, thus installing and fixing the support frame 2 and the tear AI detection equipment 4.

[0045] S2. When clamping the belt: The tear AI detection device 4 detects that the belt is torn or broken. The drive motor 20 drives the rotating disk 26 to rotate, which can drive the servo cylinder 21 to rotate. At the same time, it drives the first connecting rod 23 to rotate, causing the meshing triangular block 25 to separate. At this time, the reset spring 22 releases its 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 contacts and connects with the belt, thus clamping the belt.

[0046] S3. When disassembling the support frame or the tear AI detection device: 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 move relative to each other, so that the moving plates 6 and the moving frames 7 can be moved out of the second locking groove 16 and the first locking groove 14 respectively. Then the support frame 2 and the tear AI detection device 4 can be disassembled from the transport frame 1.

[0047] It should be noted that the specific models and specifications of the tear AI detection device 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.
