Description

Technical Field

[0001] The present invention relates to the technical field of conveyor systems, and in particular to a conveyor system based on on-line joint inspection. Background Art

[0002] In the modern industrial production system, places such as power plants, coal mines, steel mills, and ports undertake a large number of tasks for transporting bulk goods. As the core equipment for material transportation, the stable operation of the bulk conveyor system is crucial for the efficiency and continuity of the entire production process. However, there are obvious deficiencies in both traditional conveyor systems and some improved patented technologies.

[0003] The traditional conveyor system has poor flexibility and adaptability in inspection: In harsh environments such as power plants, coal mines, steel mills, and ports, manual inspection relied on by traditional conveyor systems faces many obstacles. These places usually have high temperature, high humidity, a lot of dust, severe electromagnetic interference, and relatively narrow spaces. For example, in the coal mine underground, the thick dust greatly reduces the visibility of the inspection personnel, making it difficult to see the details of the equipment; the narrow space severely restricts the movement of the inspection personnel, resulting in difficulty in comprehensively inspecting all components of the conveyor.

[0004] In addition, the belt conveyor inspection device disclosed in the patent with the patent application number 202322497840.0 also has some disadvantages:

[0005] First, it is necessary to hang an additional top track, which is difficult to install and construct in a narrow space environment.

[0006] Second, the inspection of the conveyor belt is not comprehensive, and there are large inspection blind spots during the inspection process, which easily affects the accuracy of the inspection results of the entire conveyor line.

[0007] Therefore, it is necessary to develop a conveyor system with a highly flexible inspection ability and an accurate fault monitoring and warning function to improve the safe operation of the bulk conveyor system. Summary of the Invention

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. Achieve full - range inspection and cleaning of the conveyor belt: The inner inspection unit and the outer inspection unit cooperate with each other. The inner inspection unit cleans the inner surface of the conveyor belt through the cleaning air nozzles and pulse holes, and uses the inner - surface vision sensor to collect image information; the outer inspection unit uses the bottom air nozzles to clean the outer surface of the conveyor belt and collects the outer - surface image through the outer - surface vision sensor, so as to realize the synchronous monitoring and cleaning of the inner and outer surfaces of the conveyor belt, and can timely detect defects such as cracks and damages, ensuring the safe operation of the conveyor belt.

[0026] 2. Improve the stability and reliability of the conveying system: The main lifting cylinder and the auxiliary lifting cylinder with a belt support position - adjusting mechanism cooperate with each other to accurately adjust the position and spacing of the upper idler group and the lower idler group, realizing precise adjustment of the conveyor - belt tension; ensuring that the conveyor belt maintains an appropriate tension under different working conditions, reducing wear and deviation phenomena, prolonging the service life of the conveyor belt, and thus improving the stability and reliability of the entire conveying system.

[0027] 3. Improve the inspection efficiency and automation level: When the double - clutch reciprocating mechanism and the inner - surface inspection mechanism of the inner inspection unit work, the long pipe rotates and the clutch controls the rotation of the transmission lead screw, realizing the reciprocating displacement of the sliding seat. Cooperating with the vision sensor, it automatically collects the image of the inner surface of the conveyor belt and feeds it back to the external controller. At the same time, after the sliding seat touches the position switch, it automatically switches the opening and closing state of the clutch, realizing the automation and precise control of the inspection movement and improving the inspection efficiency.

[0028] 4. Optimize power transmission and system layout: The total drive mechanism serves as the power source, drives the right - drive conveying unit through the belt drive assembly, and then drives the conveyor belt and the left - driven conveying unit to operate. At the same time, the rotation of the end axles of the left - driven conveying unit and the right - drive conveying unit drives the inner inspection unit to work, combining the functions of conveying and inspection, reducing additional power equipment, and lowering costs. The entire system layout is compact, reducing the floor area occupied by equipment and improving space utilization.

[0029] 5. Enhanced cleaning effect: Pulse holes are provided on the surface of the long tube, which cooperate with the cleaning nozzles. When the long tube rotates, the airflow ejected from the pulse holes can clean the inner edge of the conveyor belt. Moreover, the impact angle of the airflow can be adjusted and cooperate with the airflow ejected from the cleaning nozzles to cover all areas of the inner surface of the conveyor belt, expanding the cleaning range, more thoroughly removing impurities, and further improving the cleaning ability of the inner surface of the conveyor belt.

Detailed implementation mode

[0039] The embodiments of the technical solution of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solution of the present invention more clearly, so they are only examples and cannot be used to limit the protection scope of the present invention. The specific structure of the present invention is as Figures 1-7 shown in.

[0040] Embodiment 1: A conveying system based on online joint inspection includes a base 1. At both ends of the top of the base 1, a left driven conveying unit and a right driving conveying unit are installed and are cooperated by a conveyor belt 2. Both the left driven conveying unit and the right driving conveying unit are controlled by an external networked control system. A belt supporting and position adjusting mechanism is installed between the left driven conveying unit and the right driving conveying unit. An internal inspection unit is installed in the middle space of the conveyor belt 2. External inspection units are installed on the base 1 below both the left driven conveying unit and the right driving conveying unit. A main driving mechanism is installed at the right driving conveying unit. Both ends of the internal inspection unit are linked with the left driven conveying unit and the right driving conveying unit respectively.

[0041] The conveying system based on online joint inspection in the present invention mainly monitors the conveyor belt 2 for conveying bulk goods in real time. The entire conveying system is provided with a power component by the main driving mechanism. When the main driving mechanism works, it can link the conveyor belt 2, the left driven conveying unit, and the right driving conveying unit. At the same time, when the left driven conveying unit and the right driving conveying unit are running, it can output part of the power to the internal inspection unit to drive the internal inspection unit. When the internal inspection unit is running, it can reciprocate along the length direction of the conveyor belt 2. During the reciprocation process, it can maintain the state monitoring of the inner surface of the conveyor belt 2 and the rapid cleaning of the inner surface, and jointly with the external inspection units at both ends, realize the synchronous monitoring and cleaning of the inner surface and the outer surface of the conveyor belt 2.

[0042] Thus, it is ensured that the conveyor belt 2 can be inspected, monitored and surface-cleaned integrally and effectively. When the entire conveying system is in operation, the control of relevant operating parameters and the collection and recording of the monitoring results of the conveyor belt 2 by the internal inspection unit and the external inspection unit are realized by relying on the external networking control system in the prior art.

[0043] During specific operation, the main driving mechanism is started. The main driving mechanism drives the right driving conveying unit, the conveyor belt 2 and the left driven conveying unit to operate. During the operation of the conveyor belt 2, the bulk goods thereon are continuously conveyed to the right, ensuring the smoothness of the conveying.

[0044] When the left driven conveying unit and the right driving conveying unit are in operation, the end wheel shafts thereon rotate accordingly. Since large bevel gears 18 are installed at the ends of the end wheel shafts, the large bevel gears 18 will drive the small bevel gears 19 inside the double-clutch reciprocating mechanism of the internal inspection unit to operate, thereby driving the entire long tube 15 to rotate. When the long tube 15 rotates, it will drive the transmission lead screw 20 of the internal surface inspection mechanism to operate by relying on the built-in belt transmission component 23. When the transmission lead screw 20 operates, it will drive the sliding seat 24 to translate. The fixed connection between the rigid air pipe 27 and the corresponding side seat 25 enables the side seat 25 to serve as the guiding seat of the sliding seat 24, enabling it to ensure limited guiding during the translation process, so that the side seat 25 follows and shifts along the length direction of the long tube 15, ultimately achieving the purpose of following translation.

[0045] It should be noted that when driving the two long tubes 15 to rotate, only one of the driving forces of the two long tubes 15 is used to drive the transmission lead screw 20 to operate at the same time. The control is realized by alternately opening and closing the two clutches 21. When the transmission lead screw 20 operates, it drives the sliding seat 24 of the internal surface inspection mechanism to translate. During the translation process, each air pump 26 is started to spray high-pressure air flow into the rigid air pipe 27, and the air flow sprayed out through the upper and lower cleaning air nozzles 28 can realize the cleaning of the inner surface of the conveyor belt 2.

[0046] The long tube 15 is continuously rotating and is supplied with pulsed air flow from the outside at the same time. Therefore, the inner side edges of the conveyor belt 2 can be cleaned through the respective pulsed holes 31 thereon, and the all-round inner surface cleaning is realized in cooperation with the cleaning of each cleaning air nozzle 28, improving the cleaning effect.

[0047] During the conveying process of the conveyor belt 2, each inner surface vision sensor 29 can collect visual information on the inner surface structure of the cleaned conveyor belt 2, better inspect the features such as cracks and damages on the inner surface of the conveyor belt 2 and immediately upload the collected information.

[0048] While the conveyor belt 2 is running, the outer inspection units at both ends are relied on to inspect the outer sidewall of the conveyor belt 2. The outer surface is quickly cleaned by the bottom air nozzles 33. After cleaning, the outer surface vision sensors 34 collect features such as cracks and damages on the outer surface of the conveyor belt 2 and immediately upload the collected information, so as to achieve rapid inspection of the inner and outer surfaces of the conveyor belt 2 and network transmission of the inspection results.

[0049] During the rotation of the long pipe 15, the end support members at both ends play a role in end support, effectively ensuring the flexibility and stability of the long pipe 15 during rotation.

[0050] At the same time, the cross beam 38 of the end support member provides support for the stable installation of the clutch 21.

[0051] In addition, the belt support and position adjustment mechanism can drive the adjustment of the positions and relative spacing distances of the corresponding upper idler groups and lower idler groups by the synchronous telescoping of the main lifting cylinders 11 and the synchronous telescoping of the auxiliary lifting cylinders 13 of the support and tensioning components, so as to achieve the tension adjustment of the conveyor belt 2 and facilitate the quick replacement of the conveyor belt 2.

[0052] In any of the above solutions, preferably, the left driven conveying unit includes a driven roller 3. The two ends of the end wheel shaft of the driven roller 3 are respectively inserted and fitted in the left bearing seats 4 on the corresponding sides. The bottoms of the left bearing seats 4 are all fixed on the top of the base 1. The left end of the conveyor belt 2 is wound around the driven roller 3. The outer sidewalls of the end wheel shafts of the driven rollers 3 on both sides of the conveyor belt 2 are respectively connected and fitted with the corresponding ends of the inner inspection unit and drive its operation.

[0053] The driven roller 3 rotates under the drive of the conveyor belt 2, and its end wheel shaft rotates in the left bearing seat 4 to provide support for the conveyor belt 2. The outer sidewall of the end wheel shaft is connected to the end of the inner inspection unit, transmitting the rotation of the driven roller 3 to the inner inspection unit and driving the inner inspection unit to operate; it can effectively transmit the power of the conveyor belt 2 to the inner inspection unit and ensure the normal operation of the inner inspection unit. The left driven conveying unit not only supports the conveyor belt 2 but also provides power input for the inner inspection unit and is an important part of the entire conveying and inspection system.

[0054] In any of the above solutions, preferably, the right driving conveying unit includes a driving roller 5. The two ends of the end wheel shaft of the driving roller 5 are respectively inserted and fitted in the right bearing seats 6 on the corresponding sides. The bottoms of the right bearing seats 6 are all fixed on the top of the base 1. The right end of the conveyor belt 2 is wound around the driving roller 5. The outer sidewalls of the end wheel shafts of the driven rollers 3 on both sides of the conveyor belt 2 are respectively connected and fitted with the corresponding ends of the inner inspection unit and drive its operation.

[0055] The main driving mechanism drives the driving roller 5 to rotate. The end wheel shaft of the driving roller 5 rotates within the right bearing block 6, driving the conveyor belt 2 to operate. At the same time, the outer sidewall of the end wheel shaft is connected to the end of the internal inspection unit, transmitting the rotation of the driving roller 5 to the internal inspection unit to achieve the driving of the internal inspection unit. The structural design of the right driving conveyor unit is reasonable, capable of efficiently transmitting the power of the main driving mechanism to the conveyor belt 2 and the internal inspection unit, ensuring the stable operation of the entire system. As the power output unit, it provides power for the conveyor belt 2 to promote the conveying of bulk goods, and at the same time provides power support for the internal inspection unit to ensure the normal development of the inspection work.

[0056] In any of the above solutions, preferably, the main driving mechanism includes a main driving motor 7 fixedly installed inside the right bearing block 6, and a belt transmission assembly 8 is fixedly installed at the end of the end wheel shaft of the driving roller 5. The input end of the belt transmission assembly 8 is connected to the motor shaft of the main driving motor 7.

[0057] After the main driving motor 7 is started, the motor shaft drives the input end of the belt transmission assembly 8 to rotate. The belt transmission assembly 8 transmits the power to the end wheel shaft of the driving roller 5, thereby driving the driving roller 5 to rotate. The belt transmission assembly 8 has the characteristics of smooth transmission, buffering and vibration absorption, can reduce the impact during the starting and running of the motor, protect the motor and the driving roller 5, and improve the service life of the equipment. The main driving mechanism, as the power source of the entire system, provides stable power for the right driving conveyor unit, ensuring the normal operation of the conveyor belt 2 and the conveying of bulk goods.

[0058] In any of the above solutions, preferably, the belt supporting and adjusting mechanism includes an upper idler group and a lower idler group respectively arranged at the bottom of the upper belt and the top of the lower belt of the conveyor belt 2; both ends of the upper idler group and the lower idler group are respectively connected to the corresponding supporting and tensioning components, and the supporting and tensioning components are used to control the spacing between the upper idler group and the lower idler group and achieve the tensioning adjustment of the conveyor belt 2.

[0059] The supporting and tensioning component changes the tension degree of the conveyor belt 2 by adjusting the spacing between the upper idler group and the lower idler group. When it is necessary to tension the conveyor belt 2, the supporting and tensioning component makes the upper idler group and the lower idler group approach each other to increase the tension force of the conveyor belt 2; conversely, it makes the idler groups move away from each other to reduce the tension force. Through the cooperation of the idler group and the supporting and tensioning component, the tension degree of the conveyor belt 2 can be adjusted conveniently and quickly to adapt to different working conditions and changes of the conveyor belt 2. Ensure that the conveyor belt 2 operates at an appropriate tension degree, reduce the wear and deviation of the conveyor belt 2, and improve the conveying efficiency and service life of the conveyor belt 2.

[0060] Preferably, in any of the above solutions, the upper idler group is composed of a plurality of upper idlers 9 arranged at intervals along the length direction of the conveyor belt 2, the lower idler group is composed of a plurality of lower idlers 10 arranged at intervals along the length direction of the conveyor belt 2, the supporting and tensioning member includes a plurality of main lifting cylinders 11 arranged vertically. At the top of the piston rod of each main lifting cylinder 11, a lower idler sleeve 12 for movably sleeving on the outer side wall of the corresponding end of the lower idler 10 is fixedly installed. At the top of each lower idler sleeve 12, a secondary lifting cylinder 13 is fixedly installed. At the end of the piston rod of the secondary lifting cylinder 13, an upper idler sleeve 14 for movably sleeving on the outer side wall of the corresponding end of the upper idler 9 is fixedly installed. The top of the upper idler 9 abuts against the bottom of the upper belt of the conveyor belt 2, and the bottom of the lower idler 10 abuts against the top of the lower belt of the conveyor belt 2.

[0061] The piston rod of the main lifting cylinder 11 expands and contracts, driving the lower idler sleeve 12 and the lower idler 10 to move up and down, thereby adjusting the height of the lower idler group. The piston rod of the secondary lifting cylinder 13 expands and contracts, driving the upper idler sleeve 14 and the upper idler 9 to move up and down, further finely adjusting the height of the upper idler group. Through the coordinated work of the main and secondary lifting cylinders, precise adjustment of the positions and spacings of the upper idler group and the lower idler group is achieved.

[0062] This combined design of the main and secondary lifting cylinders and the idler group can achieve precise adjustment of the tension of the conveyor belt 2, improving the accuracy and flexibility of the adjustment.

[0063] Ensure that the conveyor belt 2 can maintain an appropriate tension under different working conditions, reduce the loss of the conveyor belt 2, and improve the stability and reliability of the conveying system.

[0064] Embodiment 2: Compared with Embodiment 1, the difference of this embodiment is that it further includes the following technical features:

[0065] Preferably, in any of the above solutions, the inner inspection unit includes end supports provided on the base 1 inside the outer inspection unit. A dual-clutch reciprocating mechanism is arranged between the two end supports. An inner surface inspection mechanism capable of horizontally reciprocating and shifting is provided in the middle of the dual-clutch reciprocating mechanism. The inner surface inspection mechanism is used to detect the inner surface state of the conveyor belt 2 and feed it back to the external controller. Both ends of the dual-clutch reciprocating mechanism movably pass through the end supports and are cooperatively installed on the outer side wall of the corresponding end wheel shaft.

[0066] When the end wheel shafts of the left driven conveying unit and the right driving conveying unit rotate, they drive the long pipe 15 of the double-clutch reciprocating mechanism to rotate. The rotation of the long pipe 15 drives the transmission lead screw 20 of the inner surface inspection mechanism through the built-in belt transmission component 23, causing the sliding seat 24 of the inner surface inspection mechanism to reciprocate horizontally. During the displacement process, the inner surface vision sensor 29 collects the image of the inner surface of the conveyor belt 2 and transmits the data to the external controller. This structural design makes the power transmission path of the inner inspection unit clear, and each component works together, improving the inspection efficiency. At the same time, the detection data is fed back to the external controller, which is convenient for centralized management and analysis, realizing the real-time monitoring of the state of the conveyor belt 2. The automatic inspection of the inner surface of the conveyor belt 2 is realized, and the defects on the inner surface can be found in time, providing an accurate basis for the maintenance of the conveyor belt 2, helping to prevent production accidents caused by the damage of the conveyor belt 2, and ensuring the continuity of production.

[0067] In any of the above solutions, preferably, the double-clutch reciprocating mechanism includes two steel long pipes 15. The left and right ends of the long pipe 15 respectively project outwards from the corresponding end support members in a movable manner. At the end parts of each long pipe 15, a main air supply joint 16 is movably and hermetically sleeved. At the end of the main air supply joint 16, an end shaft sleeve 17 is fixedly installed. The end shaft sleeve 17 is sleeved on the outer side wall of the corresponding end wheel shaft. The end part of the long pipe 15 projects outwards from the inner cavity of the end shaft sleeve 17 in a movable and sealed manner. On the outer side wall of the end wheel shaft inside the end shaft sleeve 17, a large bevel gear 18 is fixedly connected. At the end part of the long pipe 15, a small bevel gear 19 is fixedly connected. The large bevel gear 18 meshes with the small bevel gear 19. The setting directions of the small bevel gears 19 on the two long pipes 15 are opposite, and one is located at the left end and the other is located at the right end. Both ends of the inner surface inspection mechanism are movably sleeved on the outer side wall of the long pipe 15.

[0068] When the end wheel shaft rotates, it drives the large bevel gear 18 to rotate. The large bevel gear 18 meshes with the small bevel gear 19, causing the two long pipes 15 to rotate. Since the directions of the small bevel gears 19 on the two long pipes 15 are opposite, the rotation directions of the two long pipes 15 are opposite. When the long pipes 15 rotate, the inner surface inspection mechanism slides on the long pipes 15 to achieve the detection and cleaning of different positions on the inner surface of the conveyor belt 2. The main air supply joint 16 provides pulsed air flow for the long pipes 15 to clean the inner edge of the conveyor belt 2. The design of using double long pipes and bevel gear transmission has a compact structure and high transmission efficiency. The reverse rotation mode of the double long pipes makes the movement of the inner surface inspection mechanism more stable, can better utilize the space, and enhances the cleaning and detection effects. The sealed connection of the main air supply joint 16 and the end shaft sleeve 17 ensures the tightness of the system, prevents dust and other impurities from entering, and improves the reliability of the equipment. The efficient transmission structure ensures the normal operation of the inner inspection unit to achieve the comprehensive cleaning and detection of the inner surface of the conveyor belt 2. The reverse rotation of the double long pipes combined with the pulsed air flow cleaning can more thoroughly remove the impurities on the inner surface of the conveyor belt 2, improve the cleaning effect, and at the same time improve the accuracy of detection.

[0069] Preferably, in any of the above solutions, the inner surface inspection mechanism includes a transmission lead screw 20 arranged between the two long pipes 15. Clutches 21 are respectively installed at both ends of each transmission lead screw 20. The outer output shafts of the clutches 21 are respectively inserted and fitted through the central holes of the end supports. The outer shells of the clutches 21 are fixed on the end supports through connecting shafts 22. An internal belt transmission component 23 is fixedly installed on the outer side wall of the outer output shaft of each clutch 21. The power input end of the internal belt transmission component 23 is coaxially fixed on the outer side wall of the corresponding long pipe 15. When the long pipe 15 rotates, it drives the transmission lead screw 20 to rotate through the internal belt transmission component 23. A sliding seat 24 is fitted on the outer side wall of the transmission lead screw 20. Side seats 25 are sleeved on the outer side walls of the long pipes 15 on both sides of the sliding seat 24. Air pumps 26 are respectively installed between each side seat 25 and the sliding seat 24. Rigid air pipes 27 are installed at the outlet ends of the air pumps 26. The ends of the rigid air pipes 27 are fixed on the sliding seat 24. A number of cleaning air nozzles 28 are arranged at intervals on the upper and lower surfaces of the rigid air pipes 27.

[0070] When the long pipe 15 rotates, it drives the transmission lead screw 20 to rotate through the built-in belt transmission component 23. The clutch 21 controls the rotation of the transmission lead screw 20. When one clutch 21 engages, the corresponding transmission lead screw 20 rotates, driving the sliding seat 24 to translate on the long pipe 15. The air pump 26 delivers high-pressure air flow into the rigid air pipe 27, and the air flow sprays out from the cleaning air nozzle 28 to clean the inner surface of the conveyor belt 2. The setting of the clutch 21 can flexibly control the rotation of the transmission lead screw 20 to realize the reciprocating motion of the inner surface inspection mechanism. The belt transmission component has the characteristics of stable transmission and low noise, reducing the vibration and interference during the operation of the equipment. The layout design of the cleaning air nozzle 28 is reasonable, which can effectively cover the inner surface of the conveyor belt 2 and improve the cleaning efficiency. It realizes the efficient cleaning and precise detection of the inner surface of the conveyor belt 2. During the sliding process of the inner surface inspection mechanism, the cleaning air nozzle 28 continuously cleans the inner surface of the conveyor belt 2, and at the same time, the visual sensor real-time collects the surface state information, discovers defects in time, and ensures the normal operation of the conveyor belt 2.

[0071] Preferably, in any of the above solutions, inner surface visual sensors 29 and edge visual sensors 39 are fixedly installed on the top and bottom of the sliding seat 24 and the two side seats 25.

[0072] The inner surface visual sensor 29 moves on the long pipe 15 along with the sliding seat 24 and the side seat 25, and takes pictures of the inner surface of the conveyor belt 2 in real time. These images are transmitted to an external controller for analyzing the state of the inner surface of the conveyor belt 2. The layout design of multiple visual sensors can collect information on the inner surface of the conveyor belt 2 from different angles, improving the comprehensiveness and accuracy of detection and reducing the detection blind area. It comprehensively collects the image information of the inner surface of the conveyor belt 2, providing rich data support for accurately judging defects such as cracks and damages on the inner surface of the conveyor belt 2, helping to discover potential problems in time, perform maintenance and repair in advance, and ensure the safe operation of the conveyor belt 2. The edge visual sensor 39 is used to monitor the edge state of the conveyor belt 2.

[0073] Preferably, in any of the above solutions, the two built-in belt transmission components 23 realize the alternate driving of the current transmission lead screw 20 to rotate forward and backward by connecting or disconnecting with the corresponding clutch 21.

[0074] When a clutch 21 is engaged, the corresponding built-in belt drive component 23 drives the drive lead screw 20 to rotate forward, causing the sliding seat 24 to move in one direction; when this clutch 21 is disengaged and another clutch 21 is engaged, the other built-in belt drive component 23 drives the drive lead screw 20 to rotate in the reverse direction, causing the sliding seat 24 to move in the opposite direction, thereby realizing the reciprocating motion of the inner surface inspection mechanism. This alternating drive method can achieve the smooth reciprocating motion of the inner surface inspection mechanism, avoiding the jamming and impact that may be caused by a single drive method, and improving the operation stability and reliability of the equipment. It ensures that the inner surface inspection mechanism conducts comprehensive and continuous inspection and cleaning on the inner surface of the conveyor belt 2, improving work efficiency and ensuring that problems on the inner surface of the conveyor belt 2 can be detected and processed in a timely manner.

[0075] When the corresponding sliding seat 24 touches the position switch 30 at the end of the corresponding clutch 21, the on-off state conversion of the two clutches 21 can be achieved. When the sliding seat 24 of the inner surface inspection mechanism moves along the long tube 15 driven by the drive lead screw 20 and touches the position switch 30 at the end of the corresponding clutch 21, the position switch 30 will send a signal. After this signal is received by the control system, the control system will control the on-off state conversion of the two clutches 21. The originally engaged clutch 21 disengages, causing the corresponding drive lead screw 20 to stop rotating; while the originally disengaged clutch 21 engages, and the other built-in belt drive component 23 drives the other drive lead screw 20 to rotate, thereby changing the moving direction of the sliding seat 24 and realizing the reciprocating motion of the inner surface inspection mechanism. By controlling the conversion of the clutch 21 through the position switch 30, the automation and precise control of the movement of the inner inspection unit are achieved. Compared with manual operation or other non-precise control methods, this design can ensure that the sliding seat 24 accurately changes its moving direction when it reaches a specific position, avoiding the influence on the inspection and cleaning effects caused by excessive or insufficient movement. At the same time, it improves the reliability and stability of the system and reduces the abnormal operation caused by mechanical failures. It ensures that the inner surface inspection mechanism can conduct comprehensive and efficient inspection and cleaning work on the inner surface of the conveyor belt 2. The accurate reciprocating motion of the sliding seat 24 enables the inner surface vision sensor 29 to cover all areas of the inner surface of the conveyor belt 2, timely detecting defects such as cracks and damages; the cleaning air nozzles 28 can also evenly clean the inner surface of the conveyor belt 2, ensuring the good operating state of the conveyor belt 2, extending its service life, and guaranteeing the normal operation of the conveying system.

[0076] In any of the above solutions, preferably, the inner surface inspection mechanism completes the cleaning of the inner surface of the conveyor belt 2 through each cleaning air nozzle 28 inside it.

[0077] The air pump 26 delivers high-pressure air flow to the rigid air pipe 27, and the air flow sprays out from the cleaning air nozzles 28 on the upper and lower surfaces of the rigid air pipe 27 and directly acts on the inner surface of the conveyor belt 2 to blow off the impurities attached to the surface. The cleaning air nozzles 28 are directly installed on the inner surface inspection mechanism, which can perform cleaning while detecting, realizing the integration of the detection and cleaning functions, improving the working efficiency, and reducing the overall volume and cost of the equipment. It effectively removes the impurities on the inner surface of the conveyor belt 2, keeps the conveyor belt 2 clean, reduces the wear of the conveyor belt 2 by the impurities, extends the service life of the conveyor belt 2, and improves the operating efficiency of the conveying system at the same time.

[0078] In any of the above solutions, preferably, both ends of the long pipe 15 are blocked and provided with a plurality of pulse holes 31 communicating with its interior on the surface. Each of the main air supply joints 16 is connected to an external pulse air pump through a pipeline. By supplying high-pressure pulse gas into the long pipe 15 and discharging it through the pulse holes 31 provided on the surface of the long pipe 15, the inner surface of the conveyor belt 2 is cleaned. Each pulse hole 31 follows the rotation of the long pipe 15 to realize the adjustment of the air flow impact angle.

[0079] The external pulse air pump supplies high-pressure pulse gas into the long pipe 15, and the gas is discharged through the pulse holes 31 on the surface of the long pipe 15 to clean the inner surface of the conveyor belt 2. When the long pipe 15 rotates, the positions of the pulse holes 31 change continuously, so as to realize the adjustment of the air flow impact angle, and the inner surface of the conveyor belt 2 can be cleaned more comprehensively. The design of the pulse holes 31 and the pulse air pump enhances the cleaning effect. By adjusting the air flow impact angle, different positions on the inner surface of the conveyor belt 2 can be cleaned, reducing the cleaning blind area. Blocking both ends of the long pipe 15 ensures the stable pressure of the gas in the long pipe 15 and improves the cleaning efficiency. It further improves the cleaning ability of the inner surface of the conveyor belt 2, especially for some difficult-to-clean parts. Through the pulse air flow and angle adjustment, the impurities can be removed more effectively, ensuring the good operating state of the conveyor belt 2.

[0080] In any of the above solutions, preferably, the long pipe 15 is located in the space between the upper idler group and the lower idler group.

[0081] In any of the above solutions, preferably, the external inspection unit includes a mounting plate seat 32 fixed to the top of one end of the base 1. A plurality of bottom air nozzles 33 are installed at intervals along the width direction of the conveyor belt 2 on the mounting plate seat 32. Each of the bottom air nozzles 33 is connected to an external air pump through a pipeline. An outer surface vision sensor 34 is fixedly installed on the mounting plate seat 32 between two adjacent bottom air nozzles 33.

[0082] The external air pump conveys high-pressure air flow to the bottom air nozzle 33 through a pipeline to clean the outer surface of the conveyor belt 2. The outer surface vision sensor 34 collects images of the outer surface of the conveyor belt 2 after cleaning and transmits the data to the external controller. The layout of the bottom air nozzle 33 and the outer surface vision sensor 34 is reasonably designed, which can achieve comprehensive cleaning and detection of the outer surface of the conveyor belt 2, and has a simple structure, easy to install and maintain. Timely clean the impurities on the outer surface of the conveyor belt 2, and at the same time detect the defects on the outer surface, cooperate with the internal inspection unit to achieve all-round maintenance and management of the conveyor belt 2, and ensure the normal operation of the conveyor belt 2.

[0083] Preferably, in any of the above solutions, the end support member includes a support plate seat 35 fixedly installed on the top of the base 1. At both ends of the top of each support plate seat 35, support columns 36 are fixedly installed. At the top of each support column 36, an end pipe 37 for sleeving on the outer side wall of the long pipe 15 is fixedly installed. The two end pipes 37 are fixedly connected by a cross beam 38. A central hole for inserting the outer end output shaft of the clutch 21 is provided in the middle of the cross beam 38.

[0084] The support plate seat 35 is fixed on the base 1 to provide a stable foundation for the entire end support member. The support column 36 supports the end pipe 37, and the end pipe 37 sleeves the long pipe 15, enabling the long pipe 15 to rotate stably. The cross beam 38 connects the two end pipes 37 and provides an installation position for the clutch 21 to ensure the stable operation of the clutch 21. This structural design is stable and reliable, can effectively support each component of the internal inspection unit, reduce the vibration during the operation of the equipment, and improve the service life of the equipment. At the same time, it is convenient for the installation and maintenance of the clutch 21. Ensure the normal operation of the internal inspection unit, provide a stable support structure for the power transmission and component installation of the internal inspection unit, and indirectly improve the reliability and safety of the entire conveying system.

[0085] Specific working principle: The main driving mechanism serves as the power source of the entire system. After starting, it drives the right driving conveying unit to operate, and then drives the conveyor belt 2 and the left driven conveying unit to operate synchronously. This is because the driving roller 5 of the right driving conveying unit rotates under the action of the main driving mechanism, and the conveyor belt 2 is wound around the driving roller 5 and the driven roller 3, thereby realizing the cyclic movement of the conveyor belt 2 and ensuring the smooth conveying of bulk goods; the integration of functions such as conveying, inspection, and position adjustment is realized, making the layout of the entire system compact, reducing the floor area of the equipment, and improving the space utilization rate. The left driven conveying unit provides the functions of supporting and driven operation for the conveyor belt 2 to ensure the stability of the conveyor belt 2 during operation; the right driving conveying unit actively provides power to promote the conveying of the conveyor belt 2 and the bulk goods; the belt support and position adjustment mechanism can perform tension adjustment on the conveyor belt 2 according to its usage conditions to ensure the normal operation of the conveyor belt 2; the inner inspection unit and the outer inspection unit are respectively responsible for inspecting and cleaning the inner surface and the outer surface of the conveyor belt 2 to realize the comprehensive monitoring and maintenance of the conveyor belt 2.

[0086] After the main driving mechanism is started, the driving roller 5 of the right driving conveying unit drives the conveyor belt 2 to run, and the driven roller 3 of the left driven conveying unit rotates accordingly. At this time, the large bevel gears 18 on the end axles of the left driven conveying unit and the right driving conveying unit also rotate. The large bevel gear 18 meshes with the small bevel gear 19 inside the double-clutch reciprocating mechanism of the internal inspection unit, thereby driving the long tube 15 of the internal inspection unit to rotate. When the long tube 15 rotates, it drives the transmission lead screw 20 of the internal surface inspection mechanism to run by relying on the built-in belt transmission component 23. The transmission lead screw 20 drives the sliding seat 24 to translate, realizing the reciprocating displacement of the internal inspection unit along the length direction of the conveyor belt 2. By combining the conveying and inspection functions and using the power of the conveying unit to drive the inspection unit, additional power equipment is reduced, the cost is lowered, and at the same time, the overall operation efficiency of the system is improved. The external networking control system realizes the operation management of the entire conveying system by controlling the main driving mechanism, the internal inspection unit, and the external inspection unit. It can control the rotation speed of the main driving mechanism according to the preset parameters, and then adjust the conveying speed of the conveyor belt 2. At the same time, it receives the surface state information of the conveyor belt 2 collected by the internal inspection unit and the external inspection unit, and stores and analyzes it. The rotation of the end axles of the left driven conveying unit and the right driving conveying unit drives the large bevel gear 18 to rotate. The large bevel gear 18 meshes with the small bevel gear 19, transmitting the power to the long tube 15 of the internal inspection unit. When the long tube 15 rotates, the built-in belt transmission component 23 converts the rotational motion of the long tube 15 into the rotation of the transmission lead screw 20. The rotation of the transmission lead screw 20 pushes the sliding seat 24 to translate along the direction of the long tube 15. The side seat 25 is connected to the rigid air pipe 27, playing a guiding role to ensure the smooth movement of the sliding seat 24. In addition, the two clutches 21 work alternately according to the control instructions. When one clutch 21 is engaged, the corresponding long tube 15 drives the transmission lead screw 20 to run, driving the sliding seat 24 to translate; the other clutch 21 is disengaged to avoid interference caused by the simultaneous driving of the two long tubes 15. During the translation of the sliding seat 24, the air pump 26 is started to send high-pressure air flow into the rigid air pipe 27, and the air flow sprays out from the cleaning air nozzle 28 to clean the inner surface of the conveyor belt 2.

[0087] During the rotation of the long tube 15, the external pulse air pump supplies air into the long tube 15, and the air flows out from the pulse holes 31 on the surface of the long tube 15. As the long tube 15 rotates, the air flow ejected from the pulse holes 31 can clean the inner edge of the conveyor belt 2, cooperating with the air flow ejected from the cleaning air nozzle 28 to cover all areas of the inner surface of the conveyor belt 2. The cleaning method combining the pulse holes 31 and the cleaning air nozzle 28 expands the cleaning range, improves the comprehensiveness and effect of cleaning, and can more thoroughly remove the impurities on the inner surface of the conveyor belt 2. Further enhancing the cleaning ability of the inner surface of the conveyor belt 2, ensuring the cleanliness of the inner surface of the conveyor belt 2, reducing the erosion of the conveyor belt 2 by impurities, and prolonging the service life of the conveyor belt 2.

[0088] During the inspection tour, the inner surface vision sensor 29 is installed on the sliding seat 24 and the side seat 25. As the inner inspection unit moves, it takes real-time pictures of the inner surface of the cleaned conveyor belt 2 to obtain the image information of the inner surface of the conveyor belt 2. This image information is immediately uploaded to the external networked control system through the transmission line.

[0089] The main lifting cylinder 11 and the auxiliary lifting cylinder 13 expand and contract according to the control instructions. The main lifting cylinder 11 mainly adjusts the overall spacing between the upper idler set and the lower idler set, and the auxiliary lifting cylinder 13 further finely adjusts the height of the upper idler set. By changing the position and spacing of the idler sets, the tension adjustment of the conveyor belt 2 is realized. When replacing the conveyor belt 2, the position of the idler set can be adjusted to facilitate the disassembly and installation of the conveyor belt 2.

[0090] Ensure the normal operation of the conveyor belt 2 under different working conditions, reduce the wear and deviation of the conveyor belt 2 caused by inappropriate tension, extend the service life of the conveyor belt 2, and at the same time reduce the difficulty and time cost of replacing the conveyor belt 2.
