Abstract
Description
Technical Field
[0001] This invention relates to the field of intelligent transmission technology, and specifically to an intelligent monitoring and maintenance system and method for transmission equipment. Background Technology
[0002] Transmission equipment is equipment that transmits kinetic energy, that is, conveys force, speed, etc.; it includes mechanical transmission, hydraulic transmission, pneumatic transmission, and electric transmission equipment. With the continuous development of production technology, modern industry or service industry has placed higher demands on the stability of transmission equipment operation. For example, the increasingly developed logistics industry uses belt conveyors and sorting equipment to intelligently handle large quantities of goods. The automation and intelligence of conveying places extremely high demands on the stable operation of transmission equipment. Most conveyor lines use motor-driven belt drives. As we all know, the biggest drawback of belt drives is that when the load is too large or the belt becomes loose, it will slip, causing the transmission ratio of the belt conveyor line to become inaccurate. Since the actions of each conveyor belt in a large conveyor system are interconnected, a change in the transmission ratio of one conveyor belt may cause the entire conveyor system to become chaotic. Therefore, monitoring the transmission equipment is essential. Chinese invention patent application CN201711399510.0 discloses a monitoring device and method for the operating status of permanent magnet coupled transmission equipment. It collects various monitored data through sensors and transmitters measuring the speed of the power source drive shaft, the speed of the load shaft, the vibration of the rotating body, the body temperature, the status of the rectifier circuit, and the status of the inverter. The operating status of the transmission equipment is then determined through data analysis. However, the aforementioned patent is not applicable to the monitoring and maintenance of belt conveyor transmission equipment. The purpose of this application is to provide an intelligent monitoring and maintenance system and method for belt conveyor transmission equipment. Summary of the Invention
[0003] To address the aforementioned issues, this invention proposes an intelligent monitoring and maintenance system for transmission equipment. This system can monitor the operation of the transmission equipment of a belt conveyor in real time. It monitors the load on the transmission equipment by setting an active roller monitoring module and monitors belt slippage and other belt faults by setting a conveyor belt monitoring module.
[0004] The objective of this invention is achieved through the following technical solutions.
[0005] An intelligent monitoring and maintenance system for transmission equipment includes an active roller monitoring module, a conveyor belt monitoring module, and a data processing module. The active roller monitoring module monitors the rotation speed of the active roller, and the conveyor belt monitoring module monitors the running speed of the conveyor belt. Several conveyor belt monitoring modules are arranged along the travel direction of the conveyor belt. The data processing module receives signals from the electrical components in the intelligent monitoring and maintenance system and processes the received signals.
[0006] The intelligent monitoring and maintenance system for transmission equipment described above further includes a human-machine interaction module. The human-machine interaction module is communicatively connected to the data processing module, and the human-machine interaction module displays the information output by the data processing module in a multimedia format.
[0007] As described above, in the intelligent monitoring and maintenance system applied to transmission equipment, the human-machine interaction module is a computer, a touch screen, or a handheld terminal.
[0008] As described above, the intelligent monitoring and maintenance system applied to transmission equipment includes an active roller monitoring module comprising a detection disk and a monitoring element. The detection disk is fixedly installed at one end of the active roller, and several detection blocks are evenly distributed on the outer surface of the detection disk. A monitoring element is fixedly installed on the outer surface of the detection disk. The monitoring element is communicatively connected to the data processing module. When a detection block passes the monitoring element, the monitoring element sends a signal to the data processing module.
[0009] As described above, the intelligent monitoring and maintenance system applied to transmission equipment includes a conveyor belt monitoring module comprising a collision block, a sliding block, a guide frame, and a monitoring element. Several collision blocks are fixed at equal intervals at one end of the conveyor belt, the guide frame is fixedly installed at one end of the conveyor belt, the sliding block is linearly slidable in the guide frame, an elastic element is provided between the left end of the sliding block and the guide frame, an inclined surface is provided at the left end of the sliding block, and a monitoring element is provided below the right end of the sliding block. The monitoring element is communicatively connected to the data processing module.
[0010] When the impact block has not reached the position of the sliding block, the sliding block is in the left limit working position under the action of the elastic element, and the right end of the sliding block has not entered the inspection range of the monitoring element. When the impact block reaches the position of the sliding block, the impact block pushes the sliding block to the right, and the sliding block slides straight to the right along the guide frame. The right end of the sliding block enters the inspection range of the monitoring element, and the monitoring element sends a signal to the data processing module.
[0011] A smart monitoring and maintenance method for transmission equipment is proposed. The method uses an active roller monitoring module and a conveyor belt monitoring module to obtain the real-time operating speed of the active roller and the conveyor belt, respectively. The real-time operating speed of the active roller and the conveyor belt is compared with the theoretical operating speed of the active roller and the conveyor belt calculated based on the motor speed. If the comparison results are inconsistent, it indicates that the transmission equipment is not operating well. If the comparison results are consistent, it indicates that the transmission equipment is operating well.
[0012] A monitoring device includes a striking block, a sliding block, a guide frame, and a monitoring element. The striking block is fixed to a moving object and moves with the object. The right side of the sliding block is mounted inside the guide frame, which can slide linearly left and right. The guide frame is fixedly positioned next to the moving object. The left side of the sliding block has an inclined surface and a straight surface. An elastic element is positioned between the left side of the sliding block and the guide frame. The monitoring element is fixedly positioned below the sliding block. When the striking block has not reached the position of the sliding block, the sliding block is in its left limit working position under the action of the elastic element, and the right end of the sliding block is not within the inspection range of the monitoring element. When the striking block reaches the position of the sliding block, it first contacts the inclined surface on the left side of the sliding block, gradually pushing the sliding block to the right. The sliding block slides linearly to the right along the guide frame. When the striking block reaches the straight surface on the left side of the sliding block, the right end of the sliding block enters the inspection range of the monitoring element.
[0013] In the monitoring device described above, the elastic element is a spring.
[0014] In the monitoring device described above, the monitoring element is a proximity switch.
[0015] In the monitoring device described above, the proximity switch is fixedly mounted on switch bracket II, and switch bracket II is fixedly mounted on a stationary object.
[0016] The beneficial effects of this invention are as follows:
[0017] 1. The present invention relates to an intelligent monitoring and maintenance system for transmission equipment, which can monitor the operation of the transmission equipment of a belt conveyor in real time.
[0018] 2. The intelligent monitoring and maintenance system of the present invention, applied to transmission equipment, realizes the monitoring of the load status of transmission equipment by setting an active rotating roller monitoring module.

[0026] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0027] like Figure 1 and Figure 2 As shown, Figure 1 and Figure 2 This is a schematic diagram of the composition of an intelligent monitoring and maintenance system for transmission equipment according to an embodiment of the present invention. It should be noted that, for ease of illustrating the structural principle, some structures are highlighted in the diagram, and their dimensions do not match those used in actual operation. As shown in the diagram, the active roller 4 is connected to the output shaft of the motor 2 via a coupling 3. The motor 2 drives the active roller 4 to rotate. The conveyor belt 1, mounted on the active roller 4 and the driven roller (not shown in the diagram), rotates with the roller. Items placed on top of the conveyor belt 1 can move forward with it. To prevent overload of the conveyed items, a friction safety coupling is used for coupling 3. The friction safety coupling limits torque and provides overload protection. Specifically, standard parts from JB / T10476-2004 can be used. This coupling consists of an active end and a driven end; when overloaded, the two ends will no longer rotate synchronously. During operation, the belt conveyor not only experiences overload but also needs to prevent slippage of the conveyor belt 1. Damage to certain parts in the middle of long belt conveyor lines can also cause localized abnormal operation of the conveyor belt 1.
[0028] The intelligent monitoring and maintenance system applied to transmission equipment is used to monitor overload and abnormal operation of conveyor belt 1. The system includes an active roller monitoring module, a conveyor belt monitoring module, and a data processing module. The active roller monitoring module monitors the rotation speed of the active roller 4, and the conveyor belt monitoring module monitors the running speed of the conveyor belt 1. Several conveyor belt monitoring modules are set along the traveling direction of the conveyor belt 1. The data processing module receives signals from the electrical components in the intelligent monitoring and maintenance system and processes the received signals. Specifically, it compares the real-time data monitored by the active roller monitoring module and the conveyor belt monitoring module with the theoretical values calculated through theoretical calculations. If the comparison results are inconsistent, it indicates that the transmission equipment is operating abnormally.
[0029] Preferably, the intelligent monitoring and maintenance system further includes a human-computer interaction module, which is communicatively connected to the data processing module. The human-computer interaction module displays the information output by the data processing module in a multimedia format. Specifically, the human-computer interaction module is a computer, a touch screen, or a handheld terminal. Through the human-computer interaction module, the comparison results can be displayed intuitively in a multimedia format such as video and audio.
[0030] Furthermore, the active roller monitoring module includes a detection disk 5 and a first proximity switch 6 as the monitoring element. The detection disk 5 is designed to facilitate the detection of the signal from the first proximity switch 6. Due to the size limitations of the active roller 4, it is difficult to install multiple detection blocks 5a on it in practice. Therefore, an enlarged detection disk 5 is used to solve this problem. The detection disk 5 is fixedly installed at one end of the active roller 4. Several detection blocks 5a are evenly distributed on the outer surface of the detection disk 5. The first proximity switch 6 is fixedly installed on the outer side of the detection disk 5 and is fixedly mounted on a switch bracket I7. The switch bracket I7 is fixed to a stationary object. The first proximity switch 6 is communicatively connected to the data processing module. When a detection block 5a passes the first proximity switch 6, the first proximity switch 6 sends a signal to the data processing module. The real-time speed of the active roller 4 can be calculated by the time interval between two adjacent signals and the distance between two adjacent detection blocks 5a. Under normal operating conditions, the real-time speed of the active roller 4 is consistent with the theoretical speed transmitted to the active roller 4 through the motor 2 and coupling 3. The data processing module can calculate the theoretical speed of the active roller 4 by obtaining the speed of the motor 2.
[0031] Furthermore, the conveyor belt monitoring module includes impact blocks 8, sliding blocks 9, guide frames 10, and monitoring elements; several impact blocks 8 are fixed at equal intervals at one end of the conveyor belt 1, the guide frame 10 is fixedly installed at one end of the conveyor belt 1, the sliding blocks 9 are linearly slidable in the guide frame 10, an elastic element spring 11 is provided between the left end of the sliding block 9 and the guide frame 10, the left end of the sliding block 9 is provided with an inclined surface, and a second proximity switch 13 is provided below the right end of the sliding block 9, the second proximity switch 13 is communicatively connected to the data processing module.
[0032] When the impact block 8 has not reached the position of the sliding block 9, the sliding block 9 is in the left limit working position under the action of the elastic element, and the right end of the sliding block 9 has not entered the inspection range of the second proximity switch 13. When the impact block 8 reaches the position of the sliding block 9, the impact block 8 pushes the sliding block 9 to the right, and the sliding block 9 slides straight to the right along the guide frame 10. The right end of the sliding block 9 enters the inspection range of the second proximity switch 13, and the second proximity switch 13 sends a signal to the data processing module.
[0033] The real-time speed of this section of conveyor belt 1 can be calculated by the time interval between two adjacent signals and the distance between two adjacent impact blocks 8. Under normal operating conditions, the real-time speed of this section of conveyor belt 1 is consistent with the theoretical speed of the conveyor belt 1 driven by the drive roller 4 transmitted through the motor 2 and coupling 3. The data processing module can calculate the theoretical speed of the conveyor belt 1 by obtaining the speed of the motor 2.
[0034] This embodiment further proposes an intelligent monitoring and maintenance method for transmission equipment. The active roller monitoring module and the conveyor belt monitoring module are used to obtain the real-time operating speed of the active roller 4 and the conveyor belt 1, respectively. The real-time operating speed of the active roller 4 and the conveyor belt 1 is compared with the theoretical operating speed of the active roller 4 and the conveyor belt 1 calculated based on the speed of the motor 2. If the comparison results are inconsistent, it indicates that the transmission equipment is not operating well. If the comparison results are consistent, it indicates that the transmission equipment is operating well.
[0035] When monitoring the speed of conveyor belt 1, we did not use the method of directly monitoring the impact block 8 with the second proximity switch 13. This is because the conveyor belt 1 will vibrate during operation, and the position of the impact block 8 will also deviate when an abnormality occurs, which will make the signal detection of the second proximity switch 13 unstable. Therefore, this application proposes a monitoring device, including an impact block 8, a sliding block 9, a guide frame 10, and a second proximity switch 13. The impact block 8 is fixed on the moving object and moves with the moving object. The right side of the sliding block 9 is installed in the guide frame 10 and can slide straight left and right. That is, a sliding groove is provided on the guide frame 10, and the sliding block 9 cooperates with the sliding groove. The guide frame 10 is fixedly set next to the moving object. The left side of the sliding block 9 is provided with an inclined surface and a straight surface. A spring 11 is provided between the left side of the sliding block 9 and the guide frame 10. The monitoring element, the second proximity switch 13, is fixedly set below the sliding block 9. The second proximity switch 13 is fixedly mounted on the switch bracket II 12, and the switch bracket II 12 is fixedly mounted on the stationary object. When the impact block 8 has not reached the position of the sliding block 9, the sliding block 9 is in the left limit working position under the action of the elastic element spring 11, and the right end of the sliding block 9 has not entered the inspection range of the monitoring element. When the impact block 8 reaches the position of the sliding block 9, the impact block 8 first contacts the left inclined surface of the sliding block 9, and gradually pushes the sliding block 9 to the right. The sliding block 9 slides straight to the right along the guide frame 10. When the impact block 8 reaches the left straight surface of the sliding block 9, the right end of the sliding block 9 enters the inspection range of the monitoring element. After the impact block 8 leaves the straight surface of the sliding block 9, the sliding block 9 returns to the left limit working position under the action of the spring 11, and the second proximity switch 13 loses the signal. With this structure, the sliding block 9 always moves in the groove of the guide frame 10 and runs smoothly. The left side of the sliding block 9 can be set to a large size so that it can cover the movement range of the impact block 8. At the same time, the manufacturing cost of the sliding block 9 and the impact block 8 is very low, and they can be replaced after use and damage. If a limit switch were used directly here, the frequent operation would greatly shorten the life of the limit switch.
[0036] In this embodiment, preferably, the motor 2 can be selected as such Figure 3 The variable frequency integrated machine shown has a motor with a built-in encoder. The speed of the motor 2 is obtained through the encoder and transmitted to the data processing module. At the same time, the variable frequency motor is easy to adjust, has a wide speed range, and is more energy-efficient.
[0037] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
