Description

Technical Field

[0002] In the modern industrial production system, power plants, coal mines, steel mills, ports and other places are responsible for the transportation of a large number of bulk goods. As the core equipment for material transportation, the stable operation of bulk conveyor systems is crucial to the efficiency and continuity of the entire production process. However, at present, both traditional conveyor systems and some improved patented technologies have obvious shortcomings.

[0003] The inspection flexibility and adaptability of traditional conveyor systems are poor: In places with harsh environments such as power plants, coal mines, steel mills and ports, the manual inspections that traditional conveyor systems rely on face many obstacles. These places are usually hot, humid, dusty, and have strong electromagnetic interference, and the space is relatively narrow. For example, in coal mines, the thick dust greatly reduces the visibility of inspectors, making it difficult to see the details of the equipment; the narrow space severely restricts the movements of inspectors, making it difficult to fully inspect all parts of the conveyor.

[0004] In addition, the belt conveyor equipment inspection device disclosed in the patent application number 202322497840.0 also has some disadvantages: First, it requires additional hanging of the top rail, which makes installation difficult in a small space.

[0037] The following is a detailed description of the embodiments of the technical solution of the present invention in conjunction with 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 cannot be used to limit the scope of protection of the present invention. Figure 1-Figure 7 as shown in .

[0038] Embodiment 1: A conveying system based on online joint inspection comprises a base 1, at both ends of the top of the base 1 are installed a left driven conveying unit and a right driving conveying unit which are cooperated with a conveyor belt 2, the left driven conveying unit and the right driving conveying unit are both controlled by an external network control system, a belt support and positioning mechanism is installed between the left driven conveying unit and the right driving conveying unit, an inner inspection unit is installed in the middle space of the conveyor belt 2, outer inspection units are installed on the base 1 below the left driven conveying unit and the right driving conveying unit, a total drive mechanism is installed at the right driving conveying unit, and both ends of the inner inspection unit are respectively linked with the left driven conveying unit and the right driving conveying unit.

[0039] 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 whole conveying system is powered by the main drive mechanism. When working, the main drive mechanism 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 in operation, the power part can be output to the internal inspection unit to complete the driving of the internal inspection unit. When the internal inspection unit is in operation, it can reciprocate along the length direction of the conveyor belt 2. During the displacement process, it can maintain the status monitoring of the inner surface of the conveyor belt 2 and the rapid cleaning of the inner surface, and the external inspection units at both ends of the outside can be combined to realize the synchronous monitoring and cleaning of the inner and outer surfaces of the conveyor belt 2.

[0040] This ensures that the conveyor belt 2 is inspected and monitored as a whole and effectively, and its surface is cleaned. The entire conveying system relies on the external network control system in the prior art to control the relevant operating parameters and collect and record the monitoring results of the conveyor belt 2 by the internal inspection unit and the external inspection unit during transportation.

[0041] During specific operation, the total drive mechanism is started, and the total drive mechanism drives the right driving conveying unit, conveyor belt 2 and left driven conveying unit to operate. During the operation of conveyor belt 2, the bulk goods on it are continuously conveyed to the right to ensure the stability of transportation.

[0042] When the left driven conveying unit and the right driving conveying unit are in operation, the end axles thereon rotate accordingly. Since a large bevel gear 18 is installed at the end of the end axle, the large bevel gear 18 will drive the small bevel gear 19 inside the dual-clutch reciprocating mechanism of the inner inspection unit to rotate, thereby driving the entire long tube 15 to rotate. When the long tube 15 rotates, it will rely on the built-in belt transmission component 23 to drive the transmission screw 20 of the inner surface inspection mechanism to operate. When the transmission 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 can make the side seat 25 serve as a guide seat for the sliding seat 24, so that it can ensure limit guidance during the translation process, so that the side seat 25 follows the displacement along the length direction of the long tube 15, and finally achieves the purpose of following translation.

[0043] It should be noted that when driving the two long tubes 15 to rotate, at the same time, only one of the driving forces of the two long tubes 15 is maintained to drive the transmission screw 20 to operate, and the control is achieved by alternating opening and closing of the two clutches 21. When the transmission screw 20 operates, it drives the sliding seat 24 of the inner surface inspection mechanism to translate. During the translation process, each air pump 26 is started to spray high-pressure airflow into the rigid air pipe 27. The airflow is sprayed through the upward and downward cleaning air nozzles 28 to clean the inner surface of the conveyor belt 2.

[0044] The long tube 15 is continuously rotating and supplied with air by an external pulse airflow, so the inner edge of the conveyor belt 2 can be cleaned through the pulse holes 31 thereon, and the cleaning of the cleaning air nozzles 28 can achieve all-round inner surface cleaning to improve the cleaning effect.

[0045] During the conveying process of the conveyor belt 2, the inner surface visual sensors 29 can collect visual information on the inner surface structure of the cleaned conveyor belt 2, so as to better inspect the cracks, damage and other features of the inner surface of the conveyor belt 2 and upload the collected information in real time.

[0046] While the conveyor belt 2 is running, the outer wall of the conveyor belt 2 is inspected by the external inspection units at its two ends, and the outer surface is quickly cleaned by the bottom air nozzle 33. After cleaning, the cracks, damage and other features of the outer surface of the conveyor belt 2 are collected by each external surface visual sensor 34 and the collected information is uploaded in real time, thereby realizing rapid inspection of the inner and outer surfaces of the conveyor belt 2 and transmitting the inspection results through the network.

[0047] During the rotation of the long tube 15 , the end support members at both ends thereof play the role of end support, thereby effectively ensuring the flexibility and stability of the long tube 15 during rotation.

[0048] At the same time, the cross beam 38 of the end support member provides support for the stable installation of the clutch 21.

[0049] In addition, the belt support positioning mechanism relies on the synchronous extension and retraction of the main lifting cylinders 11 and the auxiliary lifting cylinders 13 of the supporting tensioning components to drive the adjustment of the positions and relative spacing distances of the corresponding upper roller groups and lower roller groups, thereby realizing the tensioning adjustment of the conveyor belt 2 and facilitating the rapid replacement of the conveyor belt 2.

[0050] In any of the above schemes, it is preferred that the left driven conveying unit includes a driven roller 3, and the two ends of the end wheel shaft of the driven roller 3 are respectively inserted in the left bearing seat 4 on the corresponding side, and the bottom of each left bearing seat 4 is fixed on the top of the base 1. The left end of the conveyor belt 2 is wound around the driven roller 3, and the outer side walls of the end wheel shaft of the driven roller 3 on both sides of the conveyor belt 2 are respectively connected with the corresponding ends of the internal inspection unit to drive it to operate.

[0051] The driven roller 3 rotates under the drive of the conveyor belt 2, and its end axle rotates in the left bearing seat 4 to provide support for the conveyor belt 2. The outer wall of the end axle is connected to the end of the inner patrol unit, which transmits the rotation of the driven roller 3 to the inner patrol unit and drives the inner patrol unit to operate; it can effectively transmit the power of the conveyor belt 2 to the inner patrol unit to ensure the normal operation of the inner patrol unit. The left driven conveying unit not only supports the conveyor belt 2, but also provides power input for the inner patrol unit, and is an important part of the entire conveying and patrol system.

[0052] In any of the above schemes, it is preferred that the right driving conveying unit includes a driving roller 5, and the two ends of the end wheel shaft of the driving roller 5 are respectively inserted into the right bearing seat 6 on the corresponding side, and the bottom of each right bearing seat 6 is fixed on the top of the base 1. The right end of the conveyor belt 2 is wound around the driving roller 5, and the outer side walls of the end wheel shafts of the driven rollers 3 on both sides of the conveyor belt 2 are respectively connected with the corresponding ends of the internal inspection unit to drive it to operate.

[0053] The total drive mechanism drives the drive roller 5 to rotate, and the end axle of the drive roller 5 rotates in the right bearing seat 6, driving the conveyor belt 2 to operate. At the same time, the outer wall of the end axle is connected to the end of the inner inspection unit, and the rotation of the drive roller 5 is transmitted to the inner inspection unit to drive the inner inspection unit. The structural design of the right drive conveying unit is reasonable, and it can efficiently transmit the power of the total drive mechanism to the conveyor belt 2 and the inner inspection unit to ensure the stable operation of the entire system. As a power output unit, it provides power for the conveyor belt 2 to promote bulk cargo transportation, and at the same time provides power support for the inner inspection unit to ensure the normal implementation of the inspection work.

[0054] In any of the above schemes, it is preferred that the total drive mechanism includes a total drive motor 7 fixedly mounted on the inner side of the right bearing seat 6, and a belt drive assembly 8 is fixedly mounted on the end of the end wheel shaft of the driving roller 5, and the input end of the belt drive assembly 8 is connected to the motor shaft of the total drive motor 7.

[0055] After the main drive motor 7 is started, the motor shaft drives the input end of the belt drive assembly 8 to rotate, and the belt drive assembly 8 transmits power to the end wheel shaft of the drive roller 5, thereby driving the drive roller 5 to rotate. The belt drive assembly 8 has the characteristics of smooth transmission, buffering and vibration absorption, which can reduce the impact during the start-up and operation of the motor, protect the motor and the drive roller 5, and increase the service life of the equipment. As the power source of the entire system, the main drive mechanism provides stable power for the right drive conveying unit to ensure the normal operation of the conveyor belt 2 and the transportation of bulk goods.

[0056] In any of the above schemes, it is preferred that the belt supporting and adjusting mechanism includes an upper roller group and a lower roller group respectively arranged at the bottom of the upper belt and the top of the lower belt of the conveyor belt 2; the two ends of the upper roller group and the lower roller group are respectively connected to the supporting tensioning components at their corresponding positions, and the supporting tensioning components are used to control the spacing distance between the upper roller group and the lower roller group and realize the tension adjustment of the conveyor belt 2.

[0057] The supporting tensioning component changes the tension of the conveyor belt 2 by adjusting the spacing between the upper roller group and the lower roller group. When the conveyor belt 2 needs to be tensioned, the supporting tensioning component moves the upper roller group and the lower roller group closer together to increase the tension of the conveyor belt 2; otherwise, the roller groups are moved apart to reduce the tension. Through the cooperation of the roller group and the supporting tensioning component, the tension of the conveyor belt 2 can be adjusted conveniently and quickly to adapt to different working conditions and changes in the conveyor belt 2. Ensure that the conveyor belt 2 runs under the appropriate tension, reduce the wear and deviation of the conveyor belt 2, and improve the conveying efficiency and service life of the conveyor belt 2.

[0058] In any of the above schemes, it is preferred that the upper roller group is composed of a plurality of upper rollers 9 arranged at intervals along the length direction of the conveyor belt 2, and the lower roller group is composed of a plurality of lower rollers 10 arranged at intervals along the length direction of the conveyor belt 2, and the supporting tensioning component includes a plurality of vertically arranged main lifting cylinders 11, and a lower tube sleeve 12 for movably sleeved on the outer side wall of the end of the corresponding lower roller 10 is fixedly installed on the top of the piston rod of each main lifting cylinder 11, and an auxiliary lifting cylinder 13 is fixedly installed on the top of each lower tube sleeve 12, and an upper tube sleeve 14 for movably sleeved on the outer side wall of the end of the corresponding upper roller 9 is fixedly installed on the end of the piston rod of the auxiliary lifting cylinder 13, the top of the upper roller 9 abuts against the bottom of the upper belt of the conveyor belt 2, and the bottom of the lower roller 10 abuts against the top of the lower belt of the conveyor belt 2.

[0059] The piston rod of the main lifting cylinder 11 is extended and retracted, driving the lower tube sleeve 12 and the lower roller 10 to move up and down, thereby adjusting the height of the lower roller group. The piston rod of the auxiliary lifting cylinder 13 is extended and retracted, driving the upper tube sleeve 14 and the upper roller 9 to move up and down, further fine-tuning the height of the upper roller group. Through the coordinated work of the main and auxiliary lifting cylinders, the position and spacing of the upper and lower roller groups can be accurately adjusted.

[0060] This combination design of the main and auxiliary lifting cylinders and the roller group can achieve precise adjustment of the tension of the conveyor belt 2, thereby improving the accuracy and flexibility of the adjustment.

[0061] Ensure that the conveyor belt 2 can maintain appropriate tension under different working conditions, reduce the loss of the conveyor belt 2, and improve the stability and reliability of the conveying system.

[0062] Embodiment 2: Compared with Embodiment 1, this embodiment is different in that it also includes the following technical features: In any of the above schemes, it is preferred that the inner inspection unit includes an end support member arranged on a base 1 on the inner side of the outer inspection unit, a dual-clutch reciprocating mechanism is arranged between the two end supports, and an inner surface inspection mechanism that can be horizontally reciprocated is arranged 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 an external controller, and both ends of the dual-clutch reciprocating mechanism are movable through the end support members and are mounted on the outer side walls of the corresponding end wheel axles.

[0063] When the end axles of the left driven conveying unit and the right driving conveying unit rotate, the long tube 15 of the dual-clutch reciprocating mechanism is driven to rotate. The rotation of the long tube 15 drives the transmission screw 20 of the inner surface inspection mechanism through the built-in belt transmission component 23, so that the sliding seat 24 of the inner surface inspection mechanism is horizontally reciprocated. During the displacement process, the inner surface visual sensor 29 collects the inner surface image 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 the various components work together to improve the inspection efficiency. At the same time, the detection data is fed back to the external controller for centralized management and analysis, so as to realize real-time monitoring of the status of the conveyor belt 2. Automatic inspection of the inner surface of the conveyor belt 2 is realized, and defects on the inner surface are discovered in time, providing an accurate basis for the maintenance of the conveyor belt 2, which helps to prevent production accidents caused by damage to the conveyor belt 2 and ensure the continuity of production.

[0064] In any of the above schemes, it is preferred that the dual-clutch reciprocating mechanism includes two steel long tubes 15, the left and right ends of the long tubes 15 are respectively movably extended to the outside of the corresponding end support members, and a main air supply joint 16 is movably and sealingly sleeved at the end of each of the long tubes 15, and an end shaft sleeve 17 is fixedly installed at the end of the main air supply joint 16, and the end shaft sleeve 17 is sleeved on the outer side wall of the corresponding end wheel shaft, and the end of the long tube 15 is movably and sealedly extended into the inner cavity of the end shaft sleeve 17, and a large bevel gear 18 is fixedly connected to the outer side wall of the end wheel shaft inside the end shaft sleeve 17, and a small bevel gear 19 is fixedly connected to the end of the long tube 15, and the large bevel gear 18 is meshed with the small bevel gear 19; the small bevel gears 19 on the two long tubes 15 are arranged in opposite directions and one is located at the left end and the other is located at the right end; both ends of the internal table inspection mechanism are movably sleeved on the outer side wall of the long tube 15.

[0065] When the end wheel shaft rotates, it drives the large bevel gear 18 to rotate, and the large bevel gear 18 meshes with the small bevel gear 19, so that the two long tubes 15 rotate. Since the small bevel gears 19 on the two long tubes 15 are in opposite directions, the rotation directions of the two long tubes 15 are opposite. When the long tube 15 rotates, the inner surface inspection mechanism slides on the long tube 15 to detect and clean different positions on the inner surface of the conveyor belt 2. The main air supply connector 16 provides pulse airflow for the long tube 15 to clean the inner edge of the conveyor belt 2. The design of double long tubes and bevel gear transmission has a compact structure and high transmission efficiency. The reverse rotation of the double long tubes makes the movement of the inner surface inspection mechanism more stable, and can better utilize the space, enhancing the cleaning and detection effect. The main air supply connector 16 and the end shaft sleeve 17 of the sealed sleeve ensure the sealing of the system, prevent dust and other impurities from entering, and improve the reliability of the equipment. The efficient transmission structure ensures the normal operation of the inner inspection unit and realizes comprehensive cleaning and detection of the inner surface of the conveyor belt 2. The reverse rotation of the double long tubes in combination with the pulse airflow cleaning can more thoroughly remove impurities on the inner surface of the conveyor belt 2, thereby improving the cleaning effect and the accuracy of the detection.

[0066] In any of the above schemes, it is preferred that the inner table inspection mechanism includes a transmission screw 20 arranged between two long tubes 15, and clutches 21 are respectively installed at both ends of each transmission screw 20. The outer output shaft of the clutch 21 is inserted through the center hole of the end support member, and the outer shell of each clutch 21 is fixed to the end support member through a connecting shaft 22. A built-in belt transmission component 23 is fixedly installed on the outer side wall of the outer output shaft of each clutch 21, and the power input end of the built-in belt transmission component 23 is coaxially fixed to the outer side of the corresponding long tube 15. On the wall, when the long tube 15 rotates, the transmission screw 20 is driven to rotate through the built-in belt transmission component 23, and a sliding seat 24 is installed on the outer wall of the transmission screw 20, and side seats 25 are sleeved on the outer walls of the long tube 15 on both sides of the sliding seat 24, and an air pump 26 is installed between each of the side seats 25 and the sliding seat 24, and a rigid air pipe 27 is installed at the outlet end of each of the air pumps 26, and the end of the rigid air pipe 27 is fixed on the sliding seat 24, and a plurality of cleaning air nozzles 28 are arranged at intervals on the upper and lower surfaces of the rigid air pipe 27.

[0067] When the long tube 15 rotates, the transmission screw 20 is driven to rotate through the built-in belt transmission component 23. The clutch 21 controls the rotation of the transmission screw 20. When a clutch 21 is engaged, the corresponding transmission screw 20 rotates, driving the sliding seat 24 to translate on the long tube 15. The air pump 26 delivers high-pressure airflow into the rigid air pipe 27, and the airflow is ejected 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 screw 20 to achieve the reciprocating motion of the inner surface inspection mechanism. The belt transmission component has the characteristics of smooth transmission and low noise, which reduces 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. Efficient cleaning and accurate detection of the inner surface of the conveyor belt 2 are achieved. 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 the visual sensor collects surface status information in real time, detects defects in time, and ensures the normal operation of the conveyor belt 2.

[0068] In any of the above solutions, it is preferred that an inner surface vision sensor 29 and an edge vision sensor 39 are fixedly mounted on the top and bottom of the sliding seat 24 and the two side seats 25 .

[0069] The inner surface visual sensor 29 moves on the long tube 15 with the sliding seat 24 and the side seat 25, and takes images of the inner surface of the conveyor belt 2 in real time. These images are transmitted to an external controller for analyzing the status 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, improve the comprehensiveness and accuracy of detection, and reduce detection blind spots. Comprehensive collection of image information on the inner surface of the conveyor belt 2 provides rich data support for accurately judging defects such as cracks and breakages on the inner surface of the conveyor belt 2, which helps to detect potential problems in a timely manner, perform maintenance and repairs in advance, and ensure the safe operation of the conveyor belt 2. The edge visual sensor 39 is used to monitor the edge status of the conveyor belt 2 In any of the above solutions, it is preferred that the two built-in belt transmission components 23 alternately drive the current transmission screw 20 to rotate forward and reverse by connecting or disconnecting with the corresponding clutch 21.

[0070] When one clutch 21 is engaged, the corresponding built-in belt transmission component 23 drives the transmission screw 20 to rotate forward, causing the sliding seat 24 to move in one direction; when the clutch 21 is disengaged and the other clutch 21 is engaged, the other built-in belt transmission component 23 drives the transmission screw 20 to rotate in the opposite 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 smooth reciprocating motion of the inner surface inspection mechanism, avoid the jamming and impact that may be caused by a single drive method, and improve the operating stability and reliability of the equipment. It ensures that the inner surface inspection mechanism performs comprehensive and continuous inspection and cleaning on the inner surface of the conveyor belt 2, improves work efficiency, and ensures that problems on the inner surface of the conveyor belt 2 can be discovered and handled in a timely manner.

[0071] When the corresponding sliding seat 24 touches the position switch 30 at the end of the corresponding clutch 21, the switching of the opening and closing states of the two clutches 21 can be realized. When the sliding seat 24 of the inner surface inspection mechanism moves along the long tube 15 driven by the transmission 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 switching of the opening and closing states of the two clutches 21. The originally combined clutch 21 is separated, so that the corresponding transmission screw 20 stops rotating; while the originally separated clutch 21 is combined, and the other transmission screw 20 is driven by another built-in belt transmission component 23 to rotate, thereby changing the moving direction of the sliding seat 24 and realizing the reciprocating motion of the inner surface inspection mechanism. The switching of the clutch 21 is controlled by the position switch 30, so as to realize the automation and precise control of the movement of the inner inspection unit. Compared with manual operation or other non-precise control methods, this design can ensure that the sliding seat 24 accurately changes the movement direction when it reaches a specific position, avoiding the influence of excessive or insufficient movement on the inspection and cleaning effect. At the same time, the reliability and stability of the system are improved, and the abnormal operation caused by mechanical failure is reduced. It is ensured that the inner surface inspection mechanism can perform 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 visual sensor 29 to cover various areas of the inner surface of the conveyor belt 2, and timely detect defects such as cracks and damage; the cleaning air nozzle 28 can also evenly clean the inner surface of the conveyor belt 2, ensuring the good operation of the conveyor belt 2, extending its service life, and ensuring the normal operation of the conveying system.

[0072] In any of the above schemes, it is preferred that the inner surface inspection mechanism cleans the inner surface of the conveyor belt 2 through the cleaning air nozzles 28 inside it.

[0073] The air pump 26 delivers high-pressure airflow to the rigid air pipe 27, and the airflow is ejected from the cleaning air nozzles 28 on the upper and lower surfaces of the rigid air pipe 27, directly acting on the inner surface of the conveyor belt 2 to blow away the impurities attached to the surface. The cleaning air nozzle 28 is directly installed on the inner surface inspection mechanism, and can clean while inspecting, realizing the integration of inspection and cleaning functions, improving work efficiency, and reducing the overall volume and cost of the equipment. It effectively removes 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 impurities, extends the service life of the conveyor belt 2, and improves the operating efficiency of the conveying system.

[0074] In any of the above schemes, it is preferred that both ends of the long tube 15 are sealed and a plurality of pulse holes 31 connected to the interior thereof are provided on the surface, and each of the main air supply connectors 16 is connected to an external pulse air pump through a pipeline, and high-pressure pulse gas is supplied into the long tube 15 and discharged from the pulse holes 31 provided on the surface of the long tube 15 to clean the inner surface of the conveyor belt 2, and each pulse hole 31 follows the rotation of the long tube 15 to adjust the airflow impact angle.

[0075] An external pulse air pump supplies high-pressure pulse gas into the long tube 15, and the gas is discharged through the pulse holes 31 on the surface of the long tube 15 to clean the inner surface of the conveyor belt 2. When the long tube 15 rotates, the position of the pulse hole 31 changes continuously, thereby adjusting the airflow impact angle and cleaning the inner surface of the conveyor belt 2 more comprehensively. The design of the pulse hole 31 and the pulse air pump enhances the cleaning effect. By adjusting the airflow impact angle, different positions on the inner surface of the conveyor belt 2 can be cleaned, reducing blind spots for cleaning. Blocking both ends of the long tube 15 ensures that the pressure of the gas in the long tube 15 is stable, thereby improving the cleaning efficiency. The cleaning ability of the inner surface of the conveyor belt 2 is further improved, especially for some difficult-to-clean areas. Through pulse airflow and angle adjustment, impurities can be removed more effectively to ensure the good operation of the conveyor belt 2.

[0076] In any of the above solutions, it is preferred that the long tube 15 is located in the space between the upper roller group and the lower roller group.

[0077] In any of the above schemes, it is preferred that the external inspection unit includes a mounting plate seat 32 fixed to the top of one end of the base 1, and a plurality of bottom air nozzles 33 are installed on the mounting plate seat 32 at intervals along the width direction of the conveyor belt 2, each of the bottom air nozzles 33 is connected to an external air pump through a pipeline, and an outer surface visual sensor 34 is fixedly installed on the mounting plate seat 32 between two adjacent bottom air nozzles 33.

[0078] The external air pump delivers high-pressure airflow to the bottom air nozzle 33 through the pipeline to clean the outer surface of the conveyor belt 2. The outer surface visual 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 design of the bottom air nozzle 33 and the outer surface visual sensor 34 is reasonable, which can achieve comprehensive cleaning and detection of the outer surface of the conveyor belt 2, and has a simple structure and is easy to install and maintain. The impurities on the outer surface of the conveyor belt 2 are cleaned in time, and the defects on the outer surface are detected at the same time. In cooperation with the internal inspection unit, all-round maintenance and management of the conveyor belt 2 are achieved to ensure the normal operation of the conveyor belt 2.

[0079] In any of the above schemes, it is preferred that the end support member includes a support plate seat 35 fixedly mounted on the top of the base 1, and support columns 36 are fixedly mounted at both ends of the top of each support plate seat 35, and an end tube 37 for being sleeved on the outer wall of the long tube 15 is fixedly mounted on the top of each support column 36, and the two end tubes 37 are fixedly connected by a cross beam 38, and a center hole for inserting the outer end output shaft of the clutch 21 is provided in the middle of the cross beam 38.

[0080] The support plate seat 35 is fixed on the base 1, providing a stable foundation for the entire end support. The support column 36 supports the end tube 37, and the end tube 37 is connected to the long tube 15 so that the long tube 15 can rotate stably. The crossbeam 38 connects the two end tubes 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, and can effectively support the various components of the internal inspection unit, reduce vibration during the operation of the equipment, and increase the service life of the equipment. At the same time, it is convenient for the installation and maintenance of the clutch 21. It ensures the normal operation of the internal inspection unit and provides a stable support structure for the power transmission and component installation of the internal inspection unit, which indirectly improves the reliability and safety of the entire conveying system.

[0081] Specific working principle: The total drive mechanism is the power source of the entire system. After starting, it drives the right drive conveying unit to operate, and then drives the conveyor belt 2 and the left driven conveying unit to operate synchronously. This is because the drive roller 5 of the right drive conveying unit rotates under the action of the total drive mechanism, and the conveyor belt 2 is wound around the drive roller 5 and the driven roller 3, thereby realizing the circular movement of the conveyor belt 2 and ensuring the smooth transportation of bulk goods; it realizes the integration of functions such as transportation, inspection and adjustment, making the layout of the entire system compact, reducing the floor space of the equipment and improving space utilization. The left driven conveying unit provides support and driven operation for the conveyor belt 2 to ensure the stability of the conveyor belt 2 during operation; the right drive conveying unit actively provides power to promote the transportation of the conveyor belt 2 and bulk goods; the belt support adjustment mechanism can adjust the tension of the conveyor belt 2 according to its use to ensure the normal operation of the conveyor belt 2; the inner inspection unit and the outer inspection unit are responsible for inspecting and cleaning the inner and outer surfaces of the conveyor belt 2 respectively, realizing all-round monitoring and maintenance of the conveyor belt 2.

[0082] After the total drive mechanism is started, the driving roller 5 of the right driving conveying unit drives the conveyor belt 2 to operate, and the driven roller 3 of the left driven conveying unit rotates accordingly. At this time, the large bevel gear 18 on the end axles of the left driven conveying unit and the right driving conveying unit also rotates, and the large bevel gear 18 meshes with the small bevel gear 19 inside the double clutch reciprocating mechanism of the inner patrol unit, thereby driving the long tube 15 of the inner patrol unit to rotate. When the long tube 15 rotates, the transmission screw 20 of the inner surface patrol mechanism is driven to operate by the built-in belt transmission component 23, and the transmission screw 20 drives the sliding seat 24 to translate, so as to realize the reciprocating displacement of the inner patrol unit along the length direction of the conveyor belt 2. By combining the conveying and patrol functions, the patrol unit is driven by the power of the conveying unit, which reduces the additional power equipment, reduces the cost, and improves the overall operation efficiency of the system. The external network control system realizes the operation management of the entire conveying system by controlling the total drive mechanism, the inner patrol unit and the outer patrol unit. It can control the rotation speed of the total drive 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, and the large bevel gear 18 meshes with the small bevel gear 19 to transmit 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 screw 20, and the rotation of the transmission screw 20 drives 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, which plays 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 screw 20 to operate and drives the sliding seat 24 to translate; the other clutch 21 is separated 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 deliver high-pressure airflow into the rigid air pipe 27 , and the airflow is ejected from the cleaning air nozzle 28 to clean the inner surface of the conveyor belt 2 .

[0083] During the rotation of the long tube 15, the external pulse air pump supplies air into the long tube 15, and the gas is ejected from the pulse hole 31 on the surface of the long tube 15. As the long tube 15 rotates, the airflow ejected from the pulse hole 31 can clean the inner edge of the conveyor belt 2, and cooperate with the airflow ejected from the cleaning air nozzle 28 to cover various areas of the inner surface of the conveyor belt 2. The cleaning method combining the pulse hole 31 and the cleaning air nozzle 28 expands the cleaning range, improves the comprehensiveness and effect of cleaning, and can more thoroughly remove impurities on the inner surface of the conveyor belt 2. It further improves the cleaning ability of the inner surface of the conveyor belt 2, ensures the cleanliness of the inner surface of the conveyor belt 2, reduces the erosion of impurities on the conveyor belt 2, and extends the service life of the conveyor belt 2.

[0084] During inspection, the inner surface visual sensor 29 is installed on the sliding seat 24 and the side seat 25. As the inner inspection unit moves, the inner surface of the cleaned conveyor belt 2 is photographed in real time to obtain image information of the inner surface of the conveyor belt 2. This image information is instantly uploaded to the external network control system through the transmission line.

[0085] The main lifting cylinder 11 and the auxiliary lifting cylinder 13 extend and retract according to the control command. The main lifting cylinder 11 mainly adjusts the overall spacing between the upper roller group and the lower roller group, and the auxiliary lifting cylinder 13 further fine-tunes the height of the upper roller group. By changing the position and spacing of the roller group, the tension adjustment of the conveyor belt 2 is achieved. When replacing the conveyor belt 2, the position of the roller group can be adjusted to facilitate the removal and installation of the conveyor belt 2.

[0086] The normal operation of the conveyor belt 2 under different working conditions is ensured, the wear and deviation of the conveyor belt 2 caused by inappropriate tension is reduced, the service life of the conveyor belt 2 is extended, and the difficulty and time cost of replacing the conveyor belt 2 are reduced.
