Description

Technical Field

[0001] This invention relates to the field of tape longitudinal tear detection technology, specifically to an intelligent tape longitudinal tear detection device. Background Technology

[0002] Belt conveyors, also known as belt conveyors, are mechanical devices that continuously transport materials by friction-driven processes. They can transport bulk materials and semi-finished products, and are often integrated with technological requirements in various enterprises to form assembly line transportation operations. In coal mining, belt conveyors are used to transport coal.

[0003] Currently, during coal mining and transportation, the presence of coal gangue causes uneven stress on conveyor belts, leading to belt misalignment. Furthermore, the sharp edges of the gangue can scratch the belt, causing tears. Over time, this can result in longitudinal tears. Misalignment and longitudinal tears not only cause significant coal leakage and waste, but if not detected promptly, the tears will widen, leading to more severe belt wear and increasing the difficulty of later maintenance and repair.

[0004] To prevent longitudinal tearing of tape, steel wires are usually inserted into the tape to enhance its toughness. However, since the longitudinal tearing direction of the tape is generally intersecting or even perpendicular to its conveying direction, inserting steel wires obviously cannot fundamentally solve the breakage problem caused by longitudinal tearing. Therefore, this invention provides an intelligent detection device for longitudinal tearing of tape. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an intelligent detection device for longitudinal tearing of conveyor belts. By setting a buffer component on the inner side of the annular conveyor belt and setting correction components on the front and rear sides of the annular conveyor belt, it solves the problem of the annular conveyor belt running off-center due to uneven force during coal transportation, thus preventing coal leakage. At the same time, the detection component is also set up to monitor the annular conveyor belt in real time and provide graded early warnings, so that timely measures can be taken. This solves the problems of severe wear of the annular conveyor belt caused by the inability to detect longitudinal tears in traditional conveyor belts in time, which increases the difficulty of later maintenance and repair, and the problem of the annular conveyor belt being scrapped and unable to be used normally due to excessively large tears.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] Example 1:

[0032] See Figures 1 to 5 A tape tear detection device includes a conveying assembly 1. The conveying assembly 1 includes a support leg 11. A conveying frame 12 is fixedly connected to the upper end of the support leg 11. The conveying frame 12 is symmetrically arranged front and back. A drive shaft 13 is rotatably installed between the opposite side walls of the conveying frame 12 near the left and right ends. The rear end of the drive shaft 13 on the right side extends to the rear side of the conveying frame 12 and is connected to the output shaft of the drive motor 14 through a coupling. The drive motor 14 is fixedly installed on the rear conveying frame 12 through a motor base. The front end of the drive shaft 13 on the right side extends to the front side of the conveying frame 12 and makes frictional contact with a speed sensor 15. The speed sensor 15 is fixedly installed on the front conveying frame 12. A roller 16 is fixedly installed on the drive shaft 13. An annular belt 17 is sleeved between the left and right rollers 16.

[0033] In practice, the mined coal is manually added to the upper left side of the annular belt 17, and the drive motor 14 is started. The drive motor 14 drives the drive shaft 13 and the roller 16 to rotate. Under the action of friction, the annular belt 17 will also rotate clockwise, thereby achieving the purpose of conveying the coal to the right.

[0034] Example 2:

[0035] The technical solution is basically the same as that in Embodiment 1, see below. Figures 1 to 6 The difference lies in that the upper end of the conveying component 1 is evenly provided with a buffer component 2 from left to right. The buffer component 2 includes an air storage cylinder 21. The conveying frame 12 on both the front and rear sides is evenly provided with circular through holes from left to right near the lower end. The air storage cylinder 21 is inserted into the circular through holes. A buffer unit 22 is provided in the middle of the upper end face of the air storage cylinder 21. The upper end of the buffer unit 22 is in sliding contact with the annular belt 17. Rubber air pipes 23 are installed at both ends of the air storage cylinder 21. The other end of the rubber air pipes 23 is connected to the inside of the correction component 3.

[0036] The buffer unit 22 includes a vertical cylinder 221. The upper end face of the air storage cylinder 21 is uniformly connected to the vertical cylinder 221 from front to back. A first T-shaped piston 222 is slidably arranged inside the vertical cylinder 221. A buffer plate 223 is fixedly connected to the upper end of the first T-shaped piston 222. Buffer protrusions 225 are uniformly arranged from front to back on the upper end face of the buffer plate 223. The upper end of the buffer protrusions 225 slides in contact with the upper end face of the inner side of the annular belt 17. A buffer spring 224 is arranged between two adjacent vertical cylinders 221. The lower end of the buffer spring 224 is fixedly connected to the air storage cylinder 21, and the upper end of the buffer spring 224 is fixedly connected to the buffer plate 223.

[0037] In actual operation, during the process of coal being transported to the right, the coal gangue in the coal will squeeze the annular belt 17, causing it to deform locally. At this time, the annular belt 17 will squeeze the buffer plate 223 at the corresponding position downward, and the buffer spring 224 will be compressed. At the same time, the first T-shaped piston 222 will move downward and compress the gas inside the gas storage cylinder 21. After the coal is transported, the reaction force of the buffer spring 224 will drive the buffer plate 223 and the annular belt 17 to reset, thereby ensuring the stable operation of the annular belt 17.

[0038] Example 3:

[0039] The technical solution is basically the same as that in Embodiment 2, see below. Figures 1 to 7 The difference lies in that the correction component 3 is evenly distributed from left to right on the upper surface of the conveying component 1 and located on the left side of the buffer component 2. The interior of the buffer component 2 and the interior of the correction component 3 are interconnected. The correction component 3 includes a U-shaped groove 31. A U-shaped groove 31 is provided on the conveying frame 12 on the left side of each air storage cylinder 21. A strip-shaped sliding groove 32 is symmetrically provided on the left and right side walls of the U-shaped groove 31. A correction unit 33 is provided at the bottom of the U-shaped groove 31. A rectangular slider 34 is fixedly installed on the left and right side walls of the correction unit 33. The rectangular slider 34 is slidably disposed in the strip-shaped sliding groove 32.

[0040] The correction unit 33 includes a circular air cylinder 331. The circular air cylinder 331 is slidably disposed at the bottom of the U-shaped groove 31. The interior of the circular air cylinder 331 is connected to the rubber air tube 23. A second T-shaped piston 332 is slidably disposed inside the circular air cylinder 331. A retaining spring 333 is fixedly installed between the second T-shaped piston 332 and the inner wall of the circular air cylinder 331. The end of the second T-shaped piston 332 away from the retaining spring 333 extends to the inner side of the conveyor frame 12 and is fixedly connected to a correction rod 334. The upper and lower ends of the opposite side wall of the correction rod 334 are symmetrically provided with mounting grooves.

[0041] The aforementioned correction assembly 3 also includes a rotating rod 35 and a correction wheel 36. The rotating rod 35 is rotatably installed in the mounting groove, and the correction wheel 36 is fixedly mounted on the rotating rod 35. The correction wheel 36 and the annular belt 17 slide in contact on the front and rear sides.

[0042] In actual operation, during the rotation of the annular belt 17, the compressed gas inside the air storage cylinder 21 enters the circular air cylinder 331 through the rubber air pipe 23, thereby stretching the clamping spring 333. The second T-shaped piston 332 drives the correction rod 334 to approach the annular belt 17, thereby limiting and correcting its deviation, ensuring that the annular belt 17 runs perpendicular to the conveyor frame 12. Due to the setting of the correction wheel 36, the correction rod 334 will not affect the smooth rotation of the annular belt 17.

[0043] Example 4:

[0044] The technical solution is basically the same as that in Embodiment 3, see below. Figure 1 , Figure 2 , Figure 3 and Figure 8 The difference lies in that a dust-sweeping component 4 is fixedly connected to the lower end face of the conveying component 1 near the right end. The upper end of the dust-sweeping component 4 and the lower end face of the conveying component 1 are in sliding contact. The dust-sweeping component 4 includes a U-shaped plate 41. The U-shaped plate 41 is fixedly installed on the lower end face of the conveying frame 12 near the right end. A dust-sweeping unit 42 is provided on the inner side of the U-shaped plate 41. A knocking unit 43 is connected to the left side of the dust-sweeping unit 42. Uprights 44 are symmetrically installed on the right side of the inner side of the U-shaped plate 41. A chip guide plate 45 is fixedly connected to the upper end of the uprights 44.

[0045] The dust removal unit 42 includes a rotating shaft 422. The rotating shaft 422 is rotatably mounted in the middle of the C-shaped plate 41. The front end of the rotating shaft 422 extends to the front side of the C-shaped plate 41 and is connected to the output shaft of the reciprocating motor 421 via a coupling. The rotating shaft 422 has symmetrically threaded sections 423. A reciprocating slider 424 is screw-driven on the threaded sections 423. A limit slider 425 is fixedly connected to the lower end of the reciprocating slider 424. A limit groove 426 is symmetrically opened at the bottom of the C-shaped plate 41. The lower end of the limit slider 425 is slidably mounted in the limit groove 426. A brush seat 427 is fixedly connected to the upper end of the reciprocating slider 424. Dust removal brushes 428 are evenly arranged on the upper end of the brush seat 427. The upper end of the dust removal brushes 428 slides in contact with the lower end face of the annular belt 17.

[0046] The striking unit 43 includes an L-shaped rack 431. The L-shaped rack 431 is fixedly connected to the middle of the left side wall of the reciprocating slider 424. A linkage gear 433 meshes with the right side of the L-shaped rack 431. The linkage gear 433 is mounted on the gear shaft 432 by a key connection. The lower end of the gear shaft 432 is rotatably mounted on the C-shaped plate 41. A turntable 434 is fixedly mounted on the upper end of the gear shaft 432. A striking rod 435 is connected to the turntable 434 in a figure-eight shape. The striking rods 435 are symmetrically distributed on both sides of the dust sweeping brush 428.

[0047] In actual operation, when the coal at the upper end of the annular belt 17 is transported to its right end, it will detach from the annular belt 17 under the action of inertia, while the annular belt 17 will continue to run. The lower end face of the annular belt 17 will move to the left. At this time, the reciprocating motor 421 is started, and the reciprocating motor 421 drives the rotating shaft 422 and the threaded section 423 to reciprocate. Under the limiting action of the limiting slider 425, the reciprocating slider 424 will drive the brush seat 427 and the dust sweeping brush 428 to reciprocate back and forth, thereby brushing off the coal adhering to the lower surface of the annular belt 17. The brushed coal will fall onto the chip guide plate 45, and then fall onto the side of the U-shaped plate 41 through the chip guide plate 45.

[0048] During the reciprocating motion of the reciprocating slider 424, the L-shaped rack 431 will also reciprocate. Under the action of the linkage gear 433, the gear shaft 432 and the turntable 434 will also reciprocate, thereby driving the striking rod 435 to reciprocate and strike the dust sweeping brush 428. At this time, the coal pieces mixed in the dust sweeping brush 428 will be shaken off, thereby improving the cleaning effect of the dust sweeping brush 428 and ensuring the accuracy and precision of subsequent detection and identification.

[0049] Example 5:

[0050] The technical solution is basically the same as that in Embodiment 4, see below. Figures 1 to 4 The difference is:

[0051] The detection component 5 is fixedly installed in the middle of the lower end face of the conveying component 1. A U-shaped frame 51 is fixedly installed in the middle of the lower end face of the conveying component 1. The opening of the U-shaped frame 51 faces upward. Cameras 52 are evenly installed from front to back on the bottom inner side of the U-shaped frame 51. Backing plates 53 are symmetrically arranged on the front and back sides of the camera 52. A supplementary light 54 is rotatably installed on the inner side of the backing plate 53.

[0052] In practice, after the annular belt 17 is cleaned, it continues to move to the left. Then, the camera 52 takes pictures of the belt surface of a row perpendicular to the running direction of the annular belt 17. The pictures are then transmitted to the remote brain-like intelligent box via Ethernet. The brain-like intelligent box can receive the pictures taken by each camera 52, and then stitch the images taken by multiple cameras together to form a continuous image using an image stitching algorithm. The image is then processed using image processing and correction algorithms, and then the aforementioned image is analyzed and identified using a fast image processing algorithm, feature extraction of fault images, and identification. Finally, faults such as longitudinal tears and surface damage of the annular belt 17 are analyzed and identified. At the same time, with the cooperation of the speed sensor 15, the damaged location is quickly located, and an alarm is triggered as needed. The signal is also transmitted to the remote control room, thereby stopping the part of the annular belt 17 that needs to be vulcanized or repaired at the set position to facilitate subsequent vulcanization and repair work.

[0053] It should be noted that in this invention, the detection width of the annular belt 17 is between 0 and 2 m, and the allowable detection speed is between 0 and 8 m / s.

[0054] Upon detecting a longitudinal tear in the annular belt 17, a tiered warning system will be issued, categorized into four levels: Early Warning, Key Monitoring, Requires Personnel Confirmation, and Shutdown. Early Warning indicates a tear that will not affect normal operation in the short term; real-time monitoring of the tear is required after the warning. Key Monitoring indicates a tear that is widening; close monitoring of the tear is required, with high-resolution images sent to the system's host computer at fixed intervals. Requires Personnel Confirmation indicates a tear that may affect normal operation; the system will display the captured image in real-time on the operating interface and trigger an alarm to prompt personnel for confirmation. Shutdown occurs when a longitudinal tear or large penetrating tear is detected in the annular belt 17; the system will immediately shut down.

[0055] Furthermore, in this invention, the camera 52 is a mine-use explosion-proof and intrinsically safe camera, and the supplementary light 54 is a mine-use explosion-proof supplementary light, with the specific parameters as follows:

[0056]

[0057]

[0058]

[0059] The working principle of this invention during use:

[0060] 1. The mined coal is manually added to the upper left side of the annular belt 17. The drive motor 14 is started, which drives the drive shaft 13 and roller 16 to rotate. Under the action of friction, the annular belt 17 will also rotate clockwise, thereby achieving the purpose of conveying the coal to the right.

[0061] Second: During the process of transporting coal to the right, the coal gangue in the coal will squeeze the annular belt 17, causing it to deform locally. At this time, the annular belt 17 will squeeze the buffer plate 223 at the corresponding position downward, and the buffer spring 224 will be compressed. At the same time, the first T-shaped piston 222 will move downward and compress the gas inside the gas storage cylinder 21. After the coal is transported, the reaction force of the buffer spring 224 will drive the buffer plate 223 and the annular belt 17 to reset, thereby ensuring the stable operation of the annular belt 17.

[0062] Third: During the rotation of the annular belt 17, the compressed gas inside the air storage cylinder 21 will enter the circular air cylinder 331 through the rubber air pipe 23, thereby stretching the clamping spring 333. The second T-shaped piston 332 will drive the correction rod 334 to approach the annular belt 17, thereby limiting and correcting it, ensuring that the annular belt 17 runs perpendicular to the conveyor frame 12. Due to the setting of the correction wheel 36, the correction rod 334 will not affect the smooth rotation of the annular belt 17.

[0063] Fourth: When the coal at the upper end of the annular belt 17 is transported to its right end, it will detach from the annular belt 17 due to inertia, while the annular belt 17 will continue to run. The lower end face of the annular belt 17 will move to the left. At this time, the reciprocating motor 421 is started, which drives the rotating shaft 422 and the threaded section 423 to reciprocate. Under the limiting action of the limiting slider 425, the reciprocating slider 424 will drive the brush seat 427 and the dust sweeping brush 428 to reciprocate back and forth, thereby brushing off the coal adhering to the lower surface of the annular belt 17. The coal will fall onto the chip guide plate 45, and then onto the side of the U-shaped plate 41. During the reciprocating motion of the reciprocating slider 424, the L-shaped rack 431 will reciprocate. Under the action of the linkage gear 433, the gear shaft 432 and the turntable 434 will also reciprocate, thereby driving the striking rod 435 to reciprocate to strike the dust sweeping brush 428. At this time, the coal pieces mixed in the dust sweeping brush 428 will be shaken off, thereby improving the cleaning effect of the dust sweeping brush 428 and ensuring the accuracy and precision of subsequent detection and identification.

[0064] 5. After the annular belt 17 is cleaned, it will continue to move to the left. Then, the camera 52 will take pictures of the belt surface of a row perpendicular to the running direction of the annular belt 17. The pictures will then be transmitted to the remote brain-like intelligent box via Ethernet. The brain-like intelligent box can receive the pictures taken by each camera 52, and then stitch the pictures taken by multiple cameras 52 together to form a continuous image using an image stitching algorithm. The image will then be processed using image processing and correction algorithms, and then the aforementioned image will be identified using image fast processing algorithms, fault image feature extraction and identification. Finally, the longitudinal tear, surface damage and other faults of the annular belt 17 will be analyzed and identified. At the same time, with the cooperation of the speed sensor 15, the damage location will be quickly located and an alarm will be triggered as needed. The signal will be transmitted to the remote control room, thereby stopping the part of the annular belt 17 that needs to be vulcanized or repaired at the set position to facilitate subsequent vulcanization and repair work.
