Description

Technical Field

[0001] The present invention relates to the technical field of transportation inspection, and in particular to a combined intelligent transportation system based on three-dimensional inspection. Background Art

[0002] Under harsh working conditions in industrial fields such as mines, docks, and metallurgy, material transportation mainly relies on conveyor systems with conveyor belts as the core. In particular, some special scenarios require the application of cantilevered inclined conveyors to meet special transportation path requirements.

[0003] In cantilevered inclined conveyors, one end is fixed and the other is suspended. During operation, they not only bear the weight of the material but also face interference from complex external loads such as wind and vibration. This results in complex and variable load conditions on the conveying equipment, significantly increasing the risk of failure. Furthermore, the materials transported are mostly ore, coal, and bulk cargo, which in turn cause significant wear and impact on the conveying equipment, further exacerbating the potential for equipment failure and becoming a key constraint on production efficiency and safety.

[0004] The traditional cantilever inclined conveyor system has the following defects in inspection and operation management:

[0005] First, the inspection method is limited: existing inspections mostly rely on manual labor or a single type of intelligent equipment. For cantilevered inclined conveyors, manual inspections require climbing to the suspended end to perform operations, which is not only inefficient but also poses serious safety hazards such as falls from heights and accidental damage to equipment. In addition, the use of only a single intelligent device such as a rail-mounted robot will result in limited inspection viewing angles and scope, making it difficult to cover the upper and lower surfaces, both edges, and surrounding environment of the conveyor belt, forming a blind spot for detection. As a result, early abnormalities such as exposed wire ropes and curled rubber are difficult to detect in time, which can easily lead to major accidents such as conveyor belt tears. The traditional inspection model has a high rate of missed detection of conveyor belt tears, and by the time they are discovered, significant losses have often already occurred.

[0006] Second, anomaly detection lags. For critical faults like conveyor belt tears, existing detection devices often rely on fixed thresholds or simple image recognition technology, making them unable to dynamically adapt to the complex changes in the conveyor belt's surface condition during operation on cantilevered inclined conveyors. Because the conveyor is tilted and one end is suspended in the air, the conveyor belt is unevenly stressed, increasing the probability of subtle anomalies such as exposed wires and curled rubber. Furthermore, existing detection devices are susceptible to vibration and changes in lighting, resulting in a high false alarm rate, making it difficult to meet the rapid warning requirements required under these unique operating conditions.

[0007] Based on this, it can be found that in view of the particularity of the operation of cantilever inclined conveyors, it is necessary to design a joint intelligent conveying system that can realize all-round three-dimensional inspection and intelligent and efficient abnormality detection.

[0043] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only used as examples and are not intended to limit the scope of protection of the present invention. Figures 1-10 As shown in .

[0044] Example 1: A combined intelligent conveying system based on three-dimensional inspection, comprising a ground-connected frame 1, on the top of which an inclined supporting frame 2 is fixedly installed, the right end of the supporting frame 2 is inclined upward, and a driven part and an active part are respectively installed on the left and right ends of the supporting frame 2, the driven part and the active part are connected by a ring-shaped closed conveyor belt 3, openings 4 are respectively provided on both sides of the middle of the supporting frame 2, a combined inspection device is installed in the space between the two layers of the conveyor belt 3 between the two openings 4, and a dynamic three-dimensional inspection unit is installed above the middle of the conveyor belt 3, the combined inspection device cooperates with the dynamic three-dimensional inspection unit to realize the detection of the inner and outer surfaces of the conveyor belt 3.

[0045] The floor-mounted frame 1 provides stable support for the entire system. The supporting frame 2 is fixed to the top of the floor-mounted frame 1 with its right end tilted upward. The driven and active parts at its left and right ends form a transmission structure. The circular closed conveyor belt 3 is fitted over both. When the active part operates, it drives the conveyor belt 3 in a circular motion through interlocking force and friction, and the driven parts rotate with the conveyor belt 3 to provide auxiliary support. Openings 4 on both sides of the middle of the supporting frame 2 provide installation space for the combined inspection device, which is located between the two layers of the conveyor belt 3. The dynamic three-dimensional inspection unit is located above the middle of the conveyor belt 3. Both inspect the inner and outer surfaces of the conveyor belt 3 from different positions, forming a coordinated inspection structure. The installation positions of the combined inspection device and the dynamic three-dimensional inspection unit are respectively targeted at the inner and outer surfaces of the conveyor belt 3, achieving full coverage of the inspection range.

[0046] Material transportation is achieved through the conveyor belt 3. At the same time, with the help of the cooperation of the joint inspection device and the dynamic three-dimensional inspection unit, the inner and outer surfaces of the conveyor belt 3 are inspected, realizing the integration of transportation and inspection.

[0047] The combined intelligent conveying system of the present invention can better adapt to the conveyor in an inclined state during inspection, and can cooperate with the driven parts and the active parts to realize the operation of the conveyor belt 3 during inspection. During the operation, the operation of the conveyor belt 3 is simultaneously used to provide power for the combined inspection device, thereby achieving the purpose of real-time detection of the inner surface tearing state and collision damage state of the upper and lower belts of the conveyor belt 3; at the same time, in conjunction with the dynamic inspection of the dynamic three-dimensional inspection unit above, accurate inspection along the width direction of the conveyor belt 3 is realized and relevant information on the damage state of the outer surface is collected.

[0048] Specifically, the combined inspection device mainly relies on the operation of the conveyor belt 3 when working. On the one hand, it provides power for the air supply of the comprehensive cleaning mechanism, and on the other hand, it drives the various low-level internal surface cleaners 5 and high-level internal surface cleaners 6 at the injection end to rotate in conjunction.

[0049] By automatically matching the transmission speed of the current conveyor belt 3, the air supply frequency and the rotation frequency of the low-position inner surface cleaner 5 and the high-position inner surface cleaner 6 are matched on demand without manual frequency adjustment, and automatic matching of mechanical transmission can be achieved.

[0050] In addition, the built-in wide-angle detection cameras 7 located on the left and right sides have a multiple focal length magnification function, which can effectively obtain the surface conditions of the meshing parts of the driven roller 8, the active roller 11 and the conveyor belt 3 on the corresponding side and upload the collected information in real time to achieve more comprehensive defect detection.

[0051] In actual application, the system can not only transport materials and detect the status of the conveyor belt 3, but also detect minor damage to the belt in real time during the conveying process through the linkage between the operation of the conveyor belt 3 and the joint inspection device, provide early warning for equipment maintenance, and avoid production interruptions caused by sudden damage to the conveyor belt 3.

[0052] From the perspective of energy utilization, the present invention does not require the additional setting of a special power device to power the combined inspection device. It directly uses the existing power of the conveyor belt 3 to operate, which greatly saves energy consumption and reduces the overall energy consumption cost of the equipment, which is in line with the development trend of energy conservation and consumption reduction.

[0053] At the same time, the independent power unit and its associated connection and control components are eliminated, simplifying the structure of the combined inspection device and even the entire intelligent conveying system. This not only reduces the manufacturing cost of the equipment, but also helps to reduce the equipment size and make the system layout more compact. It also reduces the probability of failure caused by the coordinated operation of multiple components and improves the reliability of equipment operation.

[0054] The power comes directly from the operation of the conveyor belt 3, and the transmission path is short and direct, which can achieve efficient use of power. It avoids the loss of energy during multiple conversions or long-distance transmission, ensures that the joint inspection device can obtain power in a timely and stable manner, and ensures that its various functions, such as the air supply of the comprehensive cleaning mechanism, the linked rotation of the low-level internal surface cleaner 5 and the high-level internal surface cleaner 6, etc., can be synchronized and coordinated with the operation of the conveyor belt 3. This power source method makes the working state of the joint inspection device closely related to the operating state of the conveyor belt 3. When the operating speed of the conveyor belt 3 changes, the power input of the joint inspection device will also change accordingly, so that it can automatically adapt to the operating rhythm of the conveyor belt 3 without the need for manual adjustment of the power parameters, achieving seamless coordination between the two and improving the system's degree of automation and work efficiency.

[0055] Based on any of the above technical solutions, further optimization is that: the tops of the left and right ends of the supporting frame 2 are provided with polished supporting surfaces, and the tops of the supporting surfaces are movably abutted against the inner surface of the upper belt of the conveyor belt 3 in a moving state.

[0056] The bearing surfaces at the top of the left and right ends of the bearing frame 2 are polished. When the conveyor belt 3 is in motion, these top surfaces form a movable abutment with the inner surface of the upper belt of the conveyor belt 3. When the conveyor belt 3 is in operation, relative sliding occurs between the inner surface of the upper belt and the bearing surfaces. The polished bearing surfaces have a low surface roughness, effectively reducing friction between the two, ensuring smoother operation of the conveyor belt 3.

[0057] Furthermore, the polished bearing surface significantly reduces the coefficient of friction with the inner surface of the upper belt of the conveyor belt 3, reducing belt wear during operation, thereby extending the service life of the conveyor belt 3 and reducing equipment maintenance costs and replacement frequency. Furthermore, the movable abutment design provides the necessary support for the upper belt, preventing it from sagging due to its own weight or material pressure, which could affect conveying, while also not hindering the normal circulation of the conveyor belt 3.

[0058] This structure provides stable support for the upper belt of the moving conveyor belt 3, ensuring that the conveyor belt 3 maintains appropriate tension and running trajectory during the conveying process, ensuring stable and continuous material transportation. In addition, by reducing friction, energy loss during the operation of the conveyor belt 3 is reduced, indirectly improving the energy utilization efficiency of the entire conveying system.

[0059] Furthermore, the contact between the bearing surface and the inner surface of the upper belt of conveyor belt 3 indirectly reflects the tension and operating status of conveyor belt 3. If conveyor belt 3 is insufficiently tensioned, the contact pressure decreases, potentially causing belt slippage. If the tension is excessively high, the contact pressure increases, exacerbating wear. By detecting changes in pressure or friction between the two, the tension of conveyor belt 3 can be determined in real time, providing a basis for dynamic adjustment and maintenance of the equipment. This additional function extends beyond its simple support function.

[0060] On the basis of any of the above technical solutions, further optimization is that: the combined inspection device is also used to achieve cleaning of the inner surface of the conveyor belt 3.

[0061] The combined inspection device, in addition to its existing function of inspecting the inner surface of the conveyor belt 3, also adds a cleaning function. Using the power provided by the conveyor belt 3's rotation, it drives its own cleaning mechanisms (such as the low-position inner surface cleaner 5 and the high-position inner surface cleaner 6 in the integrated cleaning mechanism). Through rotation and air jets, it cleans the inner surface of the conveyor belt 3, removing dust and impurities adhering to it.

[0062] Integrating the cleaning function into the joint inspection device eliminates the need for additional special cleaning equipment, simplifies the structure of the entire intelligent conveying system, reduces the equipment structure, reduces the space occupied by the equipment, and reduces the manufacturing cost and installation difficulty of the equipment.

[0063] Based on any of the above technical solutions, further optimization is that: an air supply mechanism is installed on the supporting frame 2 at the front end of the combined inspection device, and the air supply mechanism is used to drive the combined inspection device to spray pressurized airflow toward the inner surface of the conveyor belt 3.

[0064] The air supply mechanism, mounted on the supporting frame 2 at the front end of the combined inspection device, generates a pressurized airflow and delivers it to the combined inspection device. Driven by the pressurized airflow, the combined inspection device sprays the pressurized airflow onto the inner surface of the conveyor belt 3, using the impact of the airflow to remove dust, impurities, and other debris from the inner surface of the conveyor belt 3.

[0065] On the basis of any of the above technical solutions, further optimization is that: the driven member includes a driven roller 8 horizontally arranged along the width direction of the conveyor belt 3, the conveyor belt 3 adopts a toothed belt, and the driven roller 8 realizes transmission by engaging the surface teeth with the internal tooth grooves of the conveyor belt 3. A driven central shaft 9 is provided at the center of the driven roller 8, and both ends of the driven central shaft 9 are movably inserted into the corresponding left end shaft seat 10, and the left end shaft seat 10 is fixed relative to the left end of the supporting frame 2.

[0066] When the active element drives the conveyor belt 3, the meshing action of the teeth causes the conveyor belt 3 to rotate the driven roller 8. The two ends of the driven central shaft 9 are movably inserted into the left-end shaft seat 10, which is fixed to the left end of the support frame 2, providing stable support for the driven roller 8 while allowing the driven roller 8 to rotate freely. By cooperating with the active element to drive the conveyor belt 3, the teeth of the conveyor belt 3 engage with the teeth of the conveyor belt 3, transmitting power and helping to maintain the tension of the conveyor belt 3, ensuring the stable circulation of the conveyor belt 3 on the inclined support frame 2, providing the basic conditions for the operation of material conveying, the combined inspection device, and the dynamic three-dimensional inspection unit.

[0067] On the basis of any of the above technical solutions, further optimization is that: the active part includes an active roller 11 horizontally arranged along the width direction of the conveyor belt 3, and the active roller 11 realizes transmission by engaging the surface teeth with the internal tooth grooves of the conveyor belt 3. An active central shaft 12 is provided at the center of the active roller 11, and both ends of the active central shaft 12 are movably inserted on the corresponding right-end shaft seat 13. The right-end shaft seat 13 is fixedly arranged relative to the right end of the supporting frame 2, and a total drive motor 14 with a reducer 15 is fixedly installed on the rear side wall of the supporting frame 2. The total drive motor 14 is fixedly connected to the rear end end of the active central shaft 12 through the reducer 15.

[0068] The active roller 11 of the driving element is arranged horizontally along the width of the conveyor belt 3, with its surface teeth interlocking with the internal teeth of the conveyor belt 3. When the main drive motor 14 is in operation, it transmits power to the active center shaft 12 through the reducer 15, driving the active roller 11 to rotate. The active roller 11 uses the interlocking action of its surface teeth and the internal teeth of the conveyor belt 3 to drive the conveyor belt 3. The two ends of the active center shaft 12 are movably inserted into the right end shaft seat 13, which is fixed to the right end of the support frame 2, providing stable support for the active roller 11 and ensuring its flexible rotation.

[0069] As the power source component of the entire conveying system, the active component drives the active roller 11 to rotate through the main drive motor 14 via the reducer 15, and then the active roller 11 engages with the teeth of the conveyor belt 3 to provide power for the operation of the conveyor belt 3, driving the material to achieve inclined conveying, and at the same time providing a power basis for the joint inspection device, etc., to ensure the realization of the functions of the entire system.

[0070] The operating parameters of the active components (such as the current of the main drive motor 14 and the speed of the active roller 11) reflect the load on the conveyor belt 3. When conveying too much material or the conveyor belt becomes stuck, the current of the main drive motor 14 will increase and the speed will fluctuate. By monitoring these parameters, it is possible to determine in real time whether the conveyor system is in normal operation, providing a basis for fault warning and maintenance.

[0071] On the basis of any of the above technical solutions, further optimization is that: the joint inspection device includes two middle connecting plate seats 16 respectively fixedly installed at the opening 4 on both sides of the supporting frame 2, and a comprehensive cleaning mechanism is installed in the space between the two middle connecting plate seats 16. The comprehensive cleaning mechanism cleans the inner surface of the conveyor belt and the surfaces of the built-in detection units on both sides of the conveyor belt by rotating and spraying airflow.

[0072] The central connecting plate mount 16 of the combined inspection device is fixed to the openings 4 on either side of the carrier frame 2, providing stable mounting support for the integrated cleaning mechanism. Located in the space between the two central connecting plate mounts 16, the integrated cleaning mechanism rotates to expand the cleaning range while simultaneously injecting air to create impact force, cleaning the inner surface of the conveyor belt and the surfaces of the built-in detection units on both sides, removing adhering dust and impurities.

[0073] The precise positioning of the central connecting plate seat 16 provides a secure mounting base for the integrated cleaning mechanism, ensuring it remains positioned during operation due to factors such as the conveyor belt's movement, ensuring stable cleaning operations. The integrated cleaning mechanism utilizes a dual cleaning method, combining rotation and jet flow, which provides a more comprehensive and thorough cleaning of the target surface compared to a single cleaning method, improving cleaning effectiveness. This comprehensive cleaning approach encompasses both the inner surface of the conveyor belt and the surface of the internal detection unit, a thoughtful approach that prevents contamination of the internal detection unit from affecting detection accuracy.

[0074] The inner surface of the conveyor belt and the surfaces of the built-in detection units on both sides are cleaned through the rotation and jet air flow of the comprehensive cleaning mechanism, ensuring that the inner surface of the conveyor belt is clean and does not affect the detection of its damage status by the joint inspection device. At the same time, the surface of the built-in detection unit is kept clean so that it can accurately collect detection information.

[0075] The integrated cleaning mechanism adopts a dual cleaning method of rotation and jet airflow to efficiently remove surface pollutants: the rotation action enables the cleaning components (such as the toothed drums of the low-position internal surface cleaner 5 and the high-position internal surface cleaner 6) to fully contact the inner surface of the conveyor belt 3 and the surface of the built-in detection unit, removing attached dust, particles, powder and other pollutants through friction, scraping and other methods; at the same time, the jet airflow uses pressure impact to blow pollutants in gaps and blind spots away from the surface. The combination of these two methods greatly improves the thoroughness of cleaning and prevents residual pollutants from affecting the accuracy of subsequent detection.

[0076] It can also adapt to different types of pollutants: for more stubborn attached pollutants, the rotating action can provide continuous mechanical force to separate them from the surface; for light, dispersed pollutants, the jet air flow can quickly blow them away. The dual cleaning method covers the cleaning needs of pollutants of different natures and enhances the adaptability of cleaning.

[0077] At the same time, the comprehensiveness of the cleaning range is guaranteed: the rotational action can make the cleaning component rotate along its own axis, covering a certain circumferential range; the jet airflow can diffuse to the periphery, covering a wider area. The combination of the two can ensure the comprehensive cleaning of the inner surface of the conveyor belt and the surfaces of the built-in detection units on both sides, without obvious cleaning blind spots.

[0078] Assisted in determining the conveyor belt's operating status: If the inner surface of the conveyor belt 3 has abnormal protrusions, depressions, or other damage, the rotating cleaning components may experience changes in operating resistance when contacting these areas, and the jet airflow will also reflect differently at these locations. By sensing these changes (via changes in the drive motor's current), it can assist in determining whether the inner surface of the conveyor belt is damaged, providing supplementary information for the combined inspection device's detection work.

[0079] Promote centralized collection of pollutants: The rotating action can push some pollutants in a specific direction, and the jet airflow can accelerate the movement of the blown dust to the side. The combination of the two makes it easier for pollutants to fall into the aggregate guide trough 22 at the bottom of the supporting frame 2, which is convenient for centralized collection and treatment, and reduces the impact of secondary diffusion of pollutants on other parts of the equipment.

[0080] On the basis of any of the above technical solutions, further optimization is that: the comprehensive cleaning mechanism includes two low-position inner surface cleaners 5 and high-position inner surface cleaners 6 arranged at intervals in the horizontal direction, the low-position inner surface cleaner 5 is used to clean the inner surface of the upper belt of the conveyor belt 3, and the high-position inner surface cleaner 6 is used to clean the inner surface of the lower belt of the conveyor belt 3, and the front end air intake connector 17 of the low-position inner surface cleaner 5 and the front end air intake connector 17 of the high-position inner surface cleaner 6 are both movable through the rotating hole on the middle connecting plate seat 16 and extend to its outside, and then movably and sealingly plug-in cooperate with the air supply end of the air source supply mechanism.

[0081] The low-position inner surface cleaner 5 is specifically responsible for cleaning the inner surface of the upper belt of the conveyor belt 3, and the high-position inner surface cleaner 6 is specifically responsible for cleaning the inner surface of the lower belt, corresponding to different parts of the conveyor belt 3, ensuring that each area of ​​the inner surface of the conveyor belt 3 can be effectively cleaned, avoiding the accuracy of subsequent inspections affected by cleaning omissions.

[0082] The front air inlet connectors 17 of the lower and upper internal surface cleaners 5 and 6 pass through the pivot holes in the middle connecting plate base 16 and then engage with the air supply end of the air supply mechanism in a flexible and sealing manner. This connection ensures that the air supply mechanism provides a stable flow of air to both cleaners, meeting the requirements of jet air cleaning, while also allowing the cleaners to rotate during operation. Furthermore, the good sealing prevents air leakage, ensuring that the airflow pressure meets the cleaning requirements and guarantees the cleaning effect.

[0083] Since the two cleaners correspond to the upper and lower belt inner surfaces respectively, the degree of contamination on the upper and lower layers of conveyor belt 3 may vary depending on the material being conveyed. If separate cleaning is required, during actual no-load operation, the air supply mechanism can adjust the air supply pressure to the two cleaners, and thus the intensity of the jet airflow, based on the contamination status of the upper and lower inner surfaces of conveyor belt 3, to achieve differentiated cleaning of different areas. This flexible adjustment capability, unlike simple synchronous cleaning mode, improves the targetedness and efficiency of cleaning.

[0084] On the basis of any of the above technical solutions, further optimization is that: the low-position inner surface cleaner 5 and the high-position inner surface cleaner 6 simultaneously clean their respective surfaces in the working state.

[0085] During the process of cleaning the inner surface of the conveyor belt 3, the lower inner surface cleaner 5 and the upper inner surface cleaner 6 will inevitably become contaminated with dust, impurities, etc. When in operation, they clean each other and promptly remove contaminants attached to their respective surfaces, preventing the accumulation of these contaminants from affecting the cleaning effect of the cleaners on the inner surface of the conveyor belt 3. This ensures that both maintain good cleaning capabilities at all times and guarantees the continued effectiveness of the cleaning work.

[0086] If contaminants accumulate on the surface of the cleaners for a long time, they may cause increased wear on the cleaners themselves. For example, hard particles in the contaminants may scratch the cleaner surfaces during friction. Mutual cleaning can reduce this unnecessary wear, thereby extending the service life of the lower inner surface cleaner 5 and the upper inner surface cleaner 6, and reducing equipment maintenance and replacement costs.

[0087] Indirectly monitor the operating status of the cleaners: By observing the surface condition of the two cleaners after cleaning each other, it is possible to indirectly determine whether they are operating properly. If a large amount of contaminants remain on the surface of one cleaner after cleaning each other, it may indicate problems such as abnormal rotation speed, position deviation, or structural damage. This provides a basis for timely troubleshooting equipment failures, helping to identify and address potential equipment issues in advance.

[0088] The cleanliness of the cleaner's own surface affects the cleanliness of its surroundings, which in turn indirectly affects the detection accuracy of the detection unit in the combined inspection device. The lower-position internal surface cleaner 5 and the upper-position internal surface cleaner 6 clean each other, jointly maintaining the cleanliness of themselves and their surroundings. This provides a stable, clean detection environment for the detection unit and reduces detection errors caused by environmental factors. This is an additional benefit beyond its self-cleaning function.

[0089] On the basis of any of the above technical solutions, further optimization is that: the low-position inner surface cleaner 5 and the high-position inner surface cleaner 6 have the same structure and both adopt toothed rotary drum cleaners.

[0090] On the basis of any of the above technical solutions, further optimization is that: the toothed drum cleaner includes a horizontally arranged median cylindrical portion 18, and a plurality of gear teeth meshing with the toothed conveyor belt 3 are arranged on the outer wall of the median cylindrical portion 18, and a conical portion 19 is integrally formed at both ends of the median cylindrical portion 18, and a coaxial rotating shaft portion 20 is integrally formed at both ends of each of the conical portions 19, and the end of the coaxial rotating shaft portion 20 located at the front end is integrally formed and fixedly connected with the front end air intake joint 17, and a fine hole channel 21 connected to the inner cavity of the front end air intake joint 17 is provided on the outer surface of the median cylindrical portion 18 and the outer surfaces of the two conical portions 19, each of the fine hole channels 21 on the outer surface of the median cylindrical portion 18 blows vertically on the inner surface of the conveyor belt 3, and each of the fine hole channels 21 on the outer surface of the conical portion 19 blows obliquely along the width direction of the conveyor belt 3 on its inner surface and accelerates the dust blown down to move to the side.

[0091] The teeth on the outer wall of the central cylindrical portion 18 mesh with the toothed conveyor belt 3. As the conveyor belt 3 rotates, the meshing action between the teeth drives the toothed rotary drum cleaner to rotate synchronously, eliminating the need for an additional power unit and achieving efficient power transmission. Simultaneously, as the cleaner rotates, the fine-pored channels 21 on the outer surface of the central cylindrical portion 18 blow vertically across the inner surface of the conveyor belt 3, directly impacting and removing contaminants such as dust and particles adhering to that area, thereby completing the cleaning of the primary area of ​​the conveyor belt 3's inner surface.

[0092] The fine-pored channels 21 on the outer surface of the conical portion 19 blow obliquely across the width of the conveyor belt 3. This oblique airflow more precisely targets areas near the edges of the conveyor belt 3, removing contaminants from the edges. Furthermore, the lateral force generated by this oblique blowing accelerates the movement of blown dust and particles toward the sides of the conveyor belt 3, facilitating their subsequent collection by the collection chute 22 at the bottom of the support frame 2. This prevents contaminants from accumulating in the clean area and ensures a continuous cleaning effect.

[0093] The central cylindrical portion 18, conical portion 19, coaxial rotating shaft portion 20, and front air inlet connector 17 are integrally formed, providing a stable structure and excellent sealing, effectively preventing air leakage during transmission. Airflow introduced by the front air inlet connector 17 is smoothly transported through the inner cavity to the fine pores 21 of the central cylindrical portion 18 and conical portion 19, ensuring that the airflow pressure ejected from each fine pore 21 is stable and meets cleaning requirements.

[0094] Indirectly monitor the meshing status of the conveyor belt 3 and the cleaner: The meshing status of the gear teeth and the toothed shape of the conveyor belt 3 can affect the cleaner's rotational stability and cleaning effectiveness. Wear, breakage, or deformation of the gear teeth on the conveyor belt 3 can lead to increased meshing clearance or meshing instability, causing fluctuations in the cleaner's rotational speed and a corresponding change in the blowing effect of the fine-porous channel 21. By monitoring the changes in the cleanliness of the inner surface of the conveyor belt 3 after cleaning, the proper meshing status can be indirectly determined, providing a basis for equipment maintenance.

[0095] The pressure and flow rate of the airflow ejected from the fine-pore channel 21 are closely related to the operating status of the air supply mechanism. Any abnormal blowing force (e.g., a sudden decrease) from the fine-pore channel 21 in the central cylindrical portion 18 or conical portion 19 may indicate insufficient air supply from the air supply mechanism or a blockage in the fine-pore channel 21. By observing the blowing effect of the fine-pore channel 21 in different locations, it can be helpful to determine whether the air supply is normal and the fine-pore channel 21 is unobstructed, thus identifying potential air source or channel failures in advance.

[0096] On the basis of any of the above technical solutions, further optimization is that: the front and rear sides of the bottom of the supporting frame 2 are respectively bent to form a collection material guide trough 22, and the collection material guide trough 22 is located below both sides of the conveyor belt 3 and is used to collect dust, particles and powder that fall into it after being blown, and transport it downward under the action of vibration and gravity.

[0097] The collection troughs 22 are located below and on either side of the conveyor belt 3, directly in the path of dust, particles, and powder swept down by the integrated cleaning mechanism (e.g., the toothed drum cleaner). Their curved structure effectively collects and gathers these pollutants, preventing them from escaping to other parts of the support frame 2 or outside the equipment, thus avoiding secondary contamination and ensuring a clean environment around the equipment.

[0098] On the basis of any of the above technical solutions, further optimization is that: the built-in detection unit includes inner connecting shafts 23 installed at intervals on one side of the corresponding toothed drum cleaner, and the front and rear ends of the inner connecting shafts 23 are fixed on the middle connecting plate seat 16 on the corresponding side, and a built-in detection square seat 24 is fixedly installed on the middle outer wall of each inner connecting shaft 23, and built-in wide-angle detection cameras 7 are installed in an array on four circumferential planes of the built-in detection square seat 24. The two adjacent built-in wide-angle detection cameras 7 are perpendicular to each other, and the two built-in wide-angle detection cameras 7 in the upper and lower directions are used to detect the inner surface state of the upper belt, and the two built-in wide-angle detection cameras 7 in the left and right directions are used to detect the inner surface state of the lower belt.

[0099] The front and rear ends of the inner connecting shaft 23 are fixed to the central connecting plate base 16, providing a stable mounting base for the built-in detection base 24. This ensures that the built-in detection base 24 and the built-in wide-angle detection camera 7 located thereon will not shake or move during operation, ensuring the accuracy of the detection position. This fixing method can resist the influence of vibrations generated by the operation of the conveyor belt 3 and the operation of the cleaning mechanism, providing structural support for stable detection.

[0100] Built-in wide-angle inspection cameras 7 are positioned perpendicularly on four circumferential planes around the built-in inspection base 24. The vertical cameras monitor the inner surface of the upper belt, while the horizontal cameras monitor the inner surface of the lower belt. The wide-angle design expands the detection range of a single camera. The four cameras work together to achieve full coverage inspection of the inner surfaces of both the upper and lower layers of the conveyor belt 3, eliminating blind spots and fully capturing information on the inner surface conditions, such as tears and collision damage.

[0101] Since the cameras in the up and down directions and the left and right directions correspond to the inner surfaces of the upper and lower belts respectively, the detection data of different parts can be collected in a targeted manner.

[0102] While monitoring the inner surface of the conveyor belt 3, the built-in wide-angle inspection camera 7 can simultaneously monitor its cleanliness. If a certain area of ​​the inner surface still contains significant contaminants, this indicates that the toothed drum cleaner in that area is performing poorly. This could be due to factors such as worn teeth or clogged fine-pore channels 21. The information provided by the built-in wide-angle inspection camera 7 indirectly calibrates the operating status of the cleaning mechanism, providing a basis for maintenance and adjustment.

[0103] On the basis of any of the above technical solutions, further optimization is that: the dynamic three-dimensional inspection unit includes two vertical side blocks 25 respectively fixed to the outer sides of the middle connecting plate seat 16, the tops of the two vertical side blocks 25 are extended to the top of the conveyor belt 3, and a bidirectional screw rod 26 is installed at the middle position between the two vertical side blocks 25. The front and rear ends of the bidirectional screw rod 26 are movable through the rotating holes on the vertical side blocks 25 and extend to the outside thereof. A control motor 27 is fixedly installed on the rear side of the vertical side block 25. The control motor 2 The motor shaft of 7 is coaxially fixedly connected to the rear end of the bidirectional screw 26, and the external threads on the outer walls on both sides of the bidirectional screw 26 have opposite rotation directions. On the outer walls on both sides of the bidirectional screw 26, opposing sliding seats 28 are symmetrically screwed and installed, and an external environment detection camera 29 and a belt outer surface detection camera 30 are coaxially fixed on the top and bottom of each of the opposing sliding seats 28. The belt outer surface detection camera 30 cooperates with the built-in detection unit to complete the detection of the inner and outer surface conditions of the conveyor belt 3, and the detection information is uploaded to the external matching controller in real time.

[0104] The vertical side guard 25 is fixed on the outside of the middle connecting plate seat 16, and the top extends to the top of the conveyor belt 3, providing a stable installation support for the bidirectional screw 26, the control motor 27 and other components. This structural design can ensure that the bidirectional screw 26 remains stable during rotation, reduce the impact of vibration on the operation of the inspection unit, and provide a reliable structural guarantee for subsequent dynamic inspections. The control motor 27 drives the bidirectional screw 26 to rotate. Since the external threads on both sides of the bidirectional screw 26 rotate in opposite directions, it will drive the opposing slides 28 on both sides to move relative to or in opposite directions. The movement of the opposing slide 28 drives the external environment detection camera 29 and the belt outer surface detection camera 30 on it to move along the width direction of the conveyor belt 3, realizing dynamic inspection in this direction, breaking through the limitations of fixed position detection, and being able to more comprehensively cover the outer surface of the conveyor belt 3.

[0105] The belt outer surface inspection camera 30 moves with the opposing slide 28 to collect information on the damage status of the outer surface of the conveyor belt 3. It works in conjunction with the built-in inspection unit to inspect both the outer and inner surfaces, completing a comprehensive inspection of the inner and outer surfaces of the conveyor belt 3. This inspection information is uploaded to an external controller in real time for timely processing and analysis.

[0106] The external environment detection camera 29 on the top of the sliding seat 28 can detect the external environment conditions around the conveyor belt 3 in real time, such as temperature, humidity, dust concentration, etc. These environmental information are of great significance for evaluating the working conditions of the conveying system, judging whether environmental factors affect the status of the conveyor belt 3 and the detection accuracy.

[0107] The environmental information collected by the external environment detection camera 29 and the outer surface status information collected by the belt outer surface detection camera 30 can be analyzed by the controller. When it is detected that the external environment is harsh (such as excessive dust concentration) or the probability of damage to a certain area on the outer surface of the conveyor belt is high, the controller can control the control motor 27 to adjust the moving speed of the sliding seat 28, perform slow and multiple inspections in the area, improve the accuracy of the detection, and realize adaptive adjustment of the inspection strategy, surpassing the conventional mode of fixed speed inspection.

[0108] On the basis of any of the above technical solutions, further optimization is that: guide shafts 31 are installed at intervals on the left and right sides of the bidirectional screw rod 26, the front and rear ends of the guide shaft 31 are fixed on the corresponding vertical side block 25, and guide sleeves 32 are movably sleeved on the outer walls on both sides of each guide shaft 31, and the left and right ends of each opposing sliding seat 28 are fixedly connected to the outer wall of the corresponding guide sleeve 32 through a long rod 41.

[0109] The guide shaft 31 is fixed to the vertical side guard 25, providing a fixed motion trajectory for the guide sleeve 32. The counter-moving slide 28 is connected to the guide sleeve 32 via a long rod 41. When the bidirectional screw 26 drives the counter-moving slide 28 to move, the guide sleeve 32 slides along the guide shaft 31, limiting the displacement of the counter-moving slide 28 in a direction perpendicular to the guide shaft 31. This ensures that the counter-moving slide 28 can only move linearly along the guide shaft 31, preventing it from deflecting, rotating, or shaking. This ensures the smooth movement of the counter-moving slide 28, thereby ensuring that the camera on it can stably capture image information.

[0110] The sliding seat 28 will generate a certain load force during the movement and when the camera is working. The cooperation between the guide shaft 31 and the guide sleeve 32 can share part of the load, reduce the radial force borne by the bidirectional screw rod 26, and avoid the bidirectional screw rod 26 from deformation or wear due to excessive force, thereby extending the service life of the bidirectional screw rod 26 and ensuring the reliability of the mechanical transmission.

[0111] On the basis of any of the above technical solutions, further optimization is that: wear-resistant sealing rings 33 are respectively provided on the front end outer walls of the two front end air intake connectors 17, and the front end of each front end air intake connector 17 is matched and movably sealed and inserted into the interior of the air supply end corresponding to the air source supply mechanism.

[0112] A wear-resistant sealing ring 33 is mounted on the front outer wall of the front air inlet connector 17. When the front air inlet connector 17 is inserted into the air supply end of the air source supply mechanism, the sealing ring is squeezed, tightly filling the gap between the two and effectively preventing air leakage from the connection. This ensures that the pressurized airflow from the air source supply mechanism can enter the fine-pore channel 21 of the toothed drum cleaner through the front air inlet connector 17 to the maximum extent possible, ensuring the required airflow pressure and flow rate for cleaning, and maintaining the stability of the cleaning effect.

[0113] Because the front air inlet connector 17 rotates with the toothed drum cleaner during operation, it moves relative to the air supply mechanism, which can easily cause friction. The wear-resistant seal ring 33 is made of a wear-resistant material that can withstand this constant friction, reducing its own wear rate. Compared to ordinary seal rings, this significantly extends its service life and reduces seal failure and maintenance frequency caused by seal ring damage.

[0114] Example 2: Compared with Example 1, this example is different in that it also includes the following technical features:

[0115] On the basis of any of the above technical solutions, further optimization is that: the air source supply mechanism includes a pressurized air cylinder 34 arranged on the front side of the middle part of the supporting frame 2, the left end of the pressurized air cylinder 34 is sealed, and two air supply pipes 35 are installed at intervals on the inner side of the left end of the pressurized air cylinder 34, the inner ends of the air supply pipes 35 are fixed to the surface of the middle connecting plate seat 16 through flanges 36, and the air supply pipes 35 are movable and sealingly sleeved on the outer side wall of the front air inlet joint 17 at its corresponding position. When the front air inlet joint 17 rotates under the driving action of the conveyor belt 3, the front air inlet joint 17 and the air supply pipe 35 are kept sealed, and a piston rod 37 with a piston fixed on the inner end is installed in the inner cavity of the straight pipe section at the right end of the pressurized air cylinder 34. A one-way valve 38 is installed at the top of the left end of the right-end straight pipe section. The inner cavity of the one-way valve 38 is connected to the inner cavity of the pressurized gas cylinder 34. The one-way valve 38 controls the external air to enter the interior of the pressurized gas cylinder 34 and cannot flow out in the opposite direction. The right end of the piston rod 37 is movable through to the right side of the pressurized gas cylinder 34 and is movably hinged with a connecting rod 39. The right end of the connecting rod 39 is movably hinged with the end of the crank 40. The inner end of the rotating point of the crank 40 is coaxially fixed to the front end of the active central shaft 12. When the active central shaft 12 rotates, the crank 40 slider mechanism composed of the connecting rod 39, the crank 40 and the piston rod 37 can be used to achieve repeated pressurization of the pressurized gas cylinder 34. The entering pressurized gas is discharged at high speed through each fine hole channel 21 and forms an impact airflow for cleaning.

[0116] As the active central shaft 12 rotates, it drives the piston rod 37 in reciprocating motion via the crank 40 and connecting rod 39, causing the volume within the pressurized air cylinder 34 to change. A one-way valve 38 controls the flow of external air into the pressurized air cylinder 34, preventing it from flowing out. As the piston rod 37 reciprocates, the gas within the pressurized air cylinder 34 is continuously compressed, forming high-pressure gas. This high-pressure gas enters the fine-pore passage 21 of the toothed drum cleaner through the air supply pipe 35 and the front air inlet connector 17, ultimately being discharged at high speed as an impact airflow, providing sufficient and stable power to clean the inner surface of the conveyor belt 3.

[0117] The air supply pipe 35 is fixed to the middle connecting plate seat 16 through the flange 36, and the movable sealing sleeve is connected to the outer wall of the front air inlet joint 17. When the front air inlet joint 17 is driven to rotate with the conveyor belt 3, this matching method can maintain good sealing and prevent gas leakage without affecting the rotation of the front air inlet joint 17, ensuring that the air flow transmission is not hindered.

[0118] The impact airflow generated by the air supply mechanism can cooperate with the fine hole channel 21 of the toothed drum cleaner to blow vertically or obliquely on the inner surface of the conveyor belt 3, effectively removing dust, particles and other debris, and meeting the requirements of the cleaning function for airflow pressure and direction.

[0119] The air supply mechanism is powered by the rotation of the active central shaft 12, which is driven by the main drive motor 14 and originates from the same source as the operating power of the conveyor belt 3. This linkage design synchronizes the generation of airflow with the operation of the conveyor belt 3. When the speed of the conveyor belt 3 changes, the speed of the active central shaft 12 changes, and the operating frequency of the crank 40 slider mechanism also changes accordingly. The airflow pressure and flow generated by the pressurized air cylinder 34 automatically adapt to the operating state of the conveyor belt 3, eliminating the need for an additional speed control device, thereby improving the coordination and automation of the system.

[0120] The working process of the present invention is as follows:

[0121] After the system is started, the main drive motor 14 in the active part drives the active central shaft 12 to rotate through the reducer 15, and the active roller 11 rotates accordingly. The teeth on its surface engage with the internal teeth of the toothed conveyor belt 3, driving the conveyor belt 3 to operate. The driven roller 8 of the driven part rotates synchronously under the drive of the conveyor belt 3, supporting the conveyor belt 3 to maintain stable circular motion.

[0122] When the conveyor belt 3 is in operation, it provides power for the combined inspection device. This power drives the coordinated rotation of the lower and upper internal surface cleaners 5 and 6 of the integrated cleaning mechanism. These cleaners clean the inner surfaces of the upper and lower layers of the conveyor belt 3, respectively, and mutually clean their surfaces during operation. Furthermore, the power is coordinated with the air supply mechanism (comprising, for example, a pressurized air cylinder 34 in Example 2) to provide air to the integrated cleaning mechanism. The pressurized air enters the toothed drum cleaner through the front air inlet connector 17, then passes through the fine-pore channels 21 of the central cylindrical portion 18 and the conical portion 19, respectively, blowing vertically and obliquely across the inner surface of the conveyor belt 3, displacing dust and other particles to the side.

[0123] The dust, particles, etc. blown down fall into the aggregate guide trough 22 at the bottom of the supporting frame 2 and are transported downward and discharged under the action of vibration and gravity.

[0124] At the same time, the built-in wide-angle detection camera 7 of the built-in detection unit starts working. The built-in wide-angle detection camera 7 in the up and down directions detects the inner surface of the upper belt, and the built-in wide-angle detection camera 7 in the left and right directions detects the inner surface of the lower belt. The built-in wide-angle detection cameras 7 on the left and right sides can also obtain the status of the engagement parts of the driven roller 8, the active roller 11 and the conveyor belt 3 and upload the information.

[0125] In the dynamic three-dimensional inspection unit, the control motor 27 drives the bidirectional screw 26 to rotate, driving the opposing slide 28 to move along the guide shaft 31. The outer surface detection camera of the conveyor belt 3 on it performs dynamic inspection along the width direction of the conveyor belt 3, and cooperates with the built-in detection unit to complete the inner and outer surface status detection of the conveyor belt 3. The external environment detection camera 29 detects the surrounding environment, and all detection information is uploaded to the existing controller in real time.
