Description

Technical Field

[0001] The invention relates to the technical field of conveying devices, and in particular to an anti-skid device for a coal conveying belt in a power plant. Background Art

[0002] In the coal transportation system of power plants, the coal conveyor belt plays an extremely critical role. The stability and reliability of its operation are directly related to the power generation efficiency and production safety of the entire power plant. With the continuous expansion of the scale of power plants and the continuous increase in the requirements for production efficiency, traditional coal conveyor belt devices have gradually exposed many problems, which urgently need to be improved and innovated.

[0003] Traditional coal conveyor belts often face the dilemma of poor anti-slip performance. In the process of coal transportation, because the coal itself has a certain weight and a relatively rough surface, and the belt surface may be worn or contaminated with oil, dust, etc. after long-term operation, the friction between the belt and the coal and between the belt and the transmission roller is greatly reduced, which can easily cause the belt to slip. Belt slippage will not only cause a sharp decrease in coal transportation efficiency and fail to meet the demand for coal for large-scale power generation in power plants, but in severe cases it will even cause a large amount of coal to accumulate on the belt, causing the belt to bear excessive local pressure, accelerating the damage of the belt, greatly shortening the service life of the belt, and increasing the cost of equipment maintenance and replacement.

[0004] In addition, during the operation of the coal conveyor belt, coal will inevitably produce coal ash impurities, which are easily attached to the surface and inner wall of the belt. Traditional belt cleaning methods often rely on manual regular cleaning or simple fixed cleaning devices. Manual cleaning is not only labor-intensive and inefficient, but also difficult to ensure the timeliness and thoroughness of cleaning, and cannot meet the needs of continuous and efficient production of modern power plants. The fixed cleaning device is difficult to fully cover all parts of the belt due to its relatively fixed cleaning position, and it is easy to leave cleaning dead corners, resulting in continuous accumulation of coal ash impurities on the belt. On the one hand, these accumulated impurities will further aggravate the friction between the belt and the transmission components, increase the energy consumption of the equipment, and on the other hand, impurities may enter the transmission mechanism or other key parts of the belt, causing equipment failure, affecting the normal operation of the coal conveying system, and reducing the reliability and stability of power plant production.

[0005] Furthermore, the tension of the coal conveyor belt has a crucial impact on its operating performance. Traditional belt tension adjustment methods mostly use manual adjustment, such as changing the position of the weight or adjusting the length of the screw. This adjustment method is cumbersome to operate and it is difficult to accurately control the tension. In the actual production of power plants, the load of the belt will continue to change with the change of coal transportation volume. At the same time, the belt will also change its length due to its own tensile deformation, temperature changes and other factors during long-term operation. If the tension of the belt cannot be adjusted in time and accurately, the belt will slip when it is too loose, which will cause a series of problems as mentioned above; when the belt is too tight, it will increase the pressure between the belt and the drive roller, accelerate the wear of the belt and transmission components, and may even cause the belt to break, causing serious production accidents, posing a huge threat to the production safety of the power plant.

[0006] To sum up, in view of the many defects of traditional power plant coal conveyor belts in anti-slip, cleaning and tension adjustment, it is urgent to develop a new type of power plant coal conveyor belt anti-slip device to effectively solve these problems, improve the overall performance of the coal conveying system, and ensure the efficient, stable and safe operation of the power plant. Summary of the invention

[0007] 1. Overall structure

[0008] Conveyor belts and related supporting components

[0009] It includes a conveyor belt for conveying coal, friction rollers are inserted at both ends of the conveyor belt, conveyor belt shafts are inserted at the center of the friction rollers, shaft frames are rotatably sleeved at both ends of the conveyor belt shaft, and the bottom of the shaft frames on the adjacent sides are respectively provided with the same slide seat. A reducer is coaxially provided at the end of the conveyor belt shaft at one end, and a driving motor is connected to the input end of the reducer. The driving motor provides power for the operation of the entire conveyor belt, which is transmitted to the conveyor belt shaft after being reduced by the reducer, driving the friction rollers to rotate, thereby making the conveyor belt operate to transport coal.

[0010] Adjustment components

[0011] The slide seat located near the driving motor side is equipped with an adjustment component for controlling the tension of the conveyor belt. The adjustment component includes a connecting seat located at the top center of the slide seat, a screw rod is inserted in the connecting seat for horizontal sliding, a nut is provided on the screw thread sleeve, the nut is fixed to the end of the connecting seat, and an adjustment motor is coaxially provided at the end of the screw rod. The screw rod is driven to rotate by the adjustment motor, and due to the fixing effect of the nut, the screw rod slides horizontally in the connecting seat, thereby driving the slide seat to move, changing the relative position of the shaft frame, and realizing precise adjustment of the tension of the conveyor belt to adapt to different working conditions and changes of the conveyor belt during operation.

[0012] Linkage cleaning components

[0013] The inner wall of the lower part of the conveyor belt is provided with a linkage cleaning assembly for cleaning coal ash impurities. The assembly includes two groups of second brackets symmetrically arranged on both sides of the conveyor belt, and the tops of the second brackets are rotatably inserted with a rotating shaft, and the outer circumference of the rotating shaft is sleeved with a rotating roller, and the rollers on the adjacent sides are respectively sleeved with the same cleaning belt, and a number of bristles are distributed on the surface of the cleaning belt, and the ends of the bristles are in contact with the inner wall of the conveyor belt. The opposite end of the rotating shaft away from the end of the regulating motor is sleeved with a second bevel gear, and the end of the second bevel gear is meshed with the same first bevel gear. A transmission shaft is inserted in the center of the first bevel gear, and the outer circumference of the transmission shaft is rotatably sleeved with a first bracket, and the end of the transmission shaft away from the second bevel gear is provided with a joint drive assembly for driving the cleaning belt to rotate. The joint drive assembly includes a first pulley sleeved on the end of the conveyor belt shaft away from the regulating motor, and a second pulley sleeved on the end of the transmission shaft away from the second bevel gear. The second pulley and the first pulley are sleeved with the same synchronous belt. When the conveyor belt shaft rotates, the transmission shaft is driven to rotate through the transmission of the first pulley, the synchronous belt and the second pulley, and then the first bevel gear drives the second bevel gear to rotate, and finally the rotation of the cleaning belts on both sides is realized to clean the inner wall of the conveyor belt, and the cleaned coal ash impurities fall into the collection box arranged under the cleaning belt.

[0014] 2. Design features and functions of key components

[0015] Anti-skid pattern on conveyor belt surface

[0016] There are a number of anti-skid patterns evenly distributed on the surface of the conveyor belt. The design of these anti-skid patterns can significantly increase the friction between the conveyor belt and the coal, effectively preventing the coal from sliding due to gravity, inertia or other factors during transportation, ensuring that the coal can be transported stably on the conveyor belt, reducing problems such as coal spillage, and improving transportation efficiency and safety.

[0017] Speed ​​monitoring components

[0018] A horizontal frame is arranged on one side of the shaft frame, and a right-angle frame is arranged at the end of the horizontal frame. A friction roller speed sensor is arranged at the top of the right-angle frame to detect the real-time speed of the friction roller, and a conveyor belt speed sensor is arranged at the bottom of the right-angle frame to detect the real-time speed of the conveyor belt. Through these two speed sensors, the speed of the friction roller and the conveyor belt can be monitored in real time, and the monitoring data can be transmitted to the central integrated controller. The central integrated controller analyzes and processes the data according to the preset program, and can promptly detect whether the conveyor belt is slipping, loosening or other abnormal conditions. For example, when the ratio of the speed of the conveyor belt to the speed of the friction roller exceeds the normal range, it can be determined that the conveyor belt is abnormal, and then trigger corresponding control measures, such as starting the adjustment component to adjust the tension of the conveyor belt or issuing an alarm to notify the staff to conduct inspection and maintenance.

[0019] Sliding seat guide structure

[0020] The slide seat is symmetrically slidably inserted with a guide slide bar. In the process of adjusting the tension of the conveyor belt, when the adjustment motor drives the screw rod to rotate and move the slide seat, the guide slide bar provides a stable guide for the slide seat, ensuring that the slide seat can only move smoothly along the predetermined direction, avoiding the slide seat from deflecting, shaking and other unstable situations, thereby ensuring the accuracy and reliability of the conveyor belt tension adjustment, preventing damage to the conveyor belt, shaft frame and other components due to unstable slide movement, and extending the service life of the device.

[0021] The anti-skid device for the coal conveyor belt of a power plant of the present invention realizes the integration of multiple functions such as anti-skid, cleaning, automatic adjustment of tension and operation status monitoring of the conveyor belt through the coordinated work of various components, effectively improving the overall performance and automation level of the coal conveying system of the power plant, reducing manual maintenance costs and the risk of production interruption due to conveyor belt failure, and has high practical value and innovation.

[0022] Beneficial effects of the present invention:

[0023] The friction roller speed sensor and conveyor belt speed sensor set on one side of the shaft frame can accurately monitor the speed of the friction roller and the conveyor belt in real time. Once the central integrated controller detects an abnormal speed ratio between the two according to the preset conveyor belt slip judgment logic, indicating that the conveyor belt may slip, it will immediately control the motor operation and adjust the tension of the conveyor belt. This automated monitoring and adjustment mechanism can intervene in the anti-slip state of the conveyor belt at the first time and quickly restore the normal operation of the conveyor belt, effectively avoiding problems such as increased wear of the conveyor belt, reduced power transmission efficiency, and even stagnation of conveying caused by long-term slipping of the conveyor belt, further ensuring the stable operation of the coal transportation system, and reducing equipment maintenance costs and production losses caused by downtime.

[0024] Linkage cleaning design: The design of the linkage cleaning component enables the cleaning belt to perform cleaning work synchronously during the operation of the conveyor belt. When the conveyor belt shaft rotates, the cleaning belt is driven by the first pulley, synchronous belt, second pulley, transmission shaft, first bevel gear and second bevel gear of the joint drive component, and the bristles on its surface are in close contact with the inner wall of the conveyor belt to clean up the coal ash impurities attached to the inner wall of the conveyor belt. This cleaning method linked to the operation of the conveyor belt does not require an additional driving power source, and fully utilizes the power of the conveyor belt itself, which not only saves energy, but also ensures the timeliness and continuity of the cleaning work.

[0025] Reverse rotation reduces cleaning dead corners: The two sets of cleaning belts rotate in opposite directions. This design cleverly solves the problem of cleaning dead corners. In the traditional one-way cleaning method, some special parts of the inner wall of the conveyor belt, such as the edges of the adjacent cleaning belts and the edges close to the two sides of the conveyor belt, are often difficult to be thoroughly cleaned. The opposite rotation direction in this device allows the bristles to clean these parts from different directions, complementing each other, and dust impurities that may have been missed are easier to reach and clean up, greatly improving the cleaning effect. The inner wall of the conveyor belt after cleaning can maintain good smoothness, reduce the wear of the conveyor belt by coal ash impurities, extend the service life of the conveyor belt, and reduce the replacement frequency and cost of the conveyor belt. At the same time, the cleaned coal ash impurities are collected by the collection box, avoiding the scattering and accumulation of impurities around the equipment, which is conducive to maintaining a clean and hygienic working environment, reducing pollution and damage to other equipment, and further improving the reliability and stability of the entire coal transportation system.

[0026] Flexibility of the adjustment component: The structural design of the adjustment component enables precise adjustment of the tension of the conveyor belt. The adjustment motor drives the screw to slide horizontally in the connecting seat. Due to the fixing effect of the nut and the guiding effect of the guide slide rod symmetrically inserted in the slide seat, the position of the shaft frame can be changed smoothly and accurately, thereby achieving fine adjustment of the tension of the conveyor belt. This adjustment method is not affected by factors such as the length of the conveyor belt and load changes, and can adapt to the tension requirements of the conveyor belt under different working conditions. For example, when the conveyor belt is initially installed, the tension can be adjusted to an appropriate range according to the design requirements; during the operation of the conveyor belt, when the length of the conveyor belt changes due to changes in coal load, wear of the conveyor belt, or changes in ambient temperature, it can also be adjusted in time through the adjustment component to ensure that the conveyor belt is always in the best tension state.

[0027] Improve overall performance and reliability: Accurate tension adjustment is not only conducive to improving the anti-skid performance of the conveyor belt and reducing the slippage caused by improper tension, but also can ensure the stability of the conveyor belt during operation and reduce vibration and noise. Appropriate tension can also make the contact between the conveyor belt and the friction roller more uniform, reduce local wear, and extend the service life of the conveyor belt and friction roller. In addition, stable tension helps to improve the power transmission efficiency of the entire coal transportation system, reduce energy consumption, improve the overall performance and reliability of the system, and provide a strong guarantee for the long-term stable operation of the power plant.

[0040] Example 1

[0042] 1. Installation and initial setup of the device

[0043] Component Assembly

[0044] Insert the friction roller 4 into both ends of the conveyor belt 5, and then pass the conveyor belt shaft 3 through the center of the friction roller 4. Rotate and sleeve the shaft frame 1 at both ends of the conveyor belt shaft 3, and fix the bottom of the shaft frame 1 on the adjacent side on the same slide 2. Coaxially install the reducer 29 at the end of the conveyor belt shaft 3 at one end, and connect the drive motor 28 to the input end of the reducer 29.

[0045] Install the adjustment assembly: set the connection seat 7 at the top center of the slide 2, slide the screw 9 horizontally into the connection seat 7, and thread the nut 8 on the screw 9 and fix it to the end of the connection seat 7, and install the adjustment motor 6 at the end of the screw 9. At the same time, symmetrically slide and insert the guide slide 10 on the slide 2 to ensure the smooth movement of the slide 2.

[0046] Constructing a linkage cleaning assembly: two sets of second brackets 19 are symmetrically installed on both sides of the conveyor belt 5, a rotating shaft 18 is rotatably inserted on the top of the second bracket 19, and a roller 20 is sleeved on the outer circumference of the rotating shaft 18, and the same cleaning belt 21 is sleeved on the roller 20 on the adjacent side, so that the end of the bristles 22 on the surface of the cleaning belt 21 abuts against the inner wall of the conveyor belt 5. A second bevel gear 17 is sleeved on the opposite end of the rotating shaft 18 away from the end of the adjusting motor 6, and the end of the second bevel gear 17 is meshed with the same first bevel gear 16, the center of the first bevel gear 16 is inserted on the transmission shaft 14, and the first bracket 15 is rotatably sleeved on the outer circumference of the transmission shaft 14. Construct a joint drive assembly at the end of the transmission shaft 14 away from the second bevel gear 17, that is, the first pulley 11 is sleeved on the end of the conveyor belt shaft 3 away from the adjusting motor 6, and the second pulley 13 is sleeved on the end of the transmission shaft 14 away from the second bevel gear 17, and the same synchronous belt 12 is sleeved on the second pulley 13 and the first pulley 11. A collecting box 23 is placed under the cleaning belt 21 to collect the cleaned coal ash impurities. A central integrated controller 30 is installed on one side of the shaft frame 1, a horizontal frame 24 is installed horizontally on one side of the shaft frame 1, a right-angle stand 25 is installed at the end of the horizontal frame 24, a friction roller speed sensor 26 is installed at the top of the right-angle stand 25, and a conveyor belt speed sensor 27 is installed at the bottom.

[0047] Initial parameter setting and debugging

[0048] According to the design specifications and actual working requirements of the conveyor belt 5, the initial parameters of the regulating motor 6 are set through the central integrated controller 30, such as the telescopic stroke range of the screw 9 corresponding to the tension range of the conveyor belt 5, so as to ensure that the conveyor belt 5 has a suitable tension during the initial installation and its normal operation without excessive looseness or over-tightness. At the same time, the friction roller speed sensor 26 and the conveyor belt speed sensor 27 are calibrated so that they can accurately measure the real-time speed of the friction roller 4 and the conveyor belt 5. The drive motor 28 and the regulating motor 6 are tested and debugged to check whether their running direction, speed regulation and other functions are normal.

[0049] 2. Normal operation process

[0050] Coal transportation

[0051] The driving motor 28 is started, and the power of the driving motor 28 is transmitted to the conveyor belt shaft 3 through the reducer 29. The conveyor belt shaft 3 drives the friction roller 4 to rotate. Due to the effect of friction, the conveyor belt 5 starts to run along the friction roller 4, and transports the coal from one end to the other end. During the transportation process, the anti-skid pattern 51 on the surface of the conveyor belt 5 increases the friction between the conveyor belt 5 and the coal, preventing the coal from sliding during the transportation process.

[0052] Linked cleaning

[0053] When the conveyor belt shaft 3 rotates, the first pulley 11 mounted thereon rotates synchronously. The second pulley 13 starts to rotate through the transmission of the synchronous belt 12, thereby driving the transmission shaft 14 to rotate. The first bevel gear 16 on the transmission shaft 14 rotates accordingly, and the second bevel gears 17 at both ends meshing with the first bevel gear 16 rotate in the opposite direction, driving the corresponding rotating shafts 18 on both sides to rotate, so that the cleaning belts 21 on the rollers 20 on both sides rotate in opposite directions. The bristles 22 on the surface of the cleaning belt 21 are in close contact with the inner wall of the conveyor belt 5, sweeping away the coal ash impurities on the inner wall of the conveyor belt 5, and the swept coal ash impurities fall into the collection box 23 below under the action of gravity. Since the two sets of cleaning belts 21 rotate in opposite directions, the bristles 22 sweep from different directions at different parts of the inner wall of the conveyor belt 5, effectively avoiding cleaning dead corners and enhancing the cleaning effect of stubborn impurities.

[0054] Speed ​​monitoring and feedback

[0055] During operation, the friction roller speed sensor 26 monitors the speed of the friction roller 4 in real time, and the conveyor belt speed sensor 27 monitors the speed of the conveyor belt 5 in real time. These speed data are transmitted to the central integrated controller 30, and the central integrated controller 30 analyzes the data according to a preset program. If it is found that the speed ratio of the friction roller 4 and the conveyor belt 5 is abnormal, for example, when the conveyor belt 5 slips and causes its speed to be lower than the normal range, the central integrated controller 30 can issue an alarm signal to prompt the operator to check and handle it, and can also try to automatically adjust the tension of the conveyor belt 5 according to the set program.

[0056] 3. Adjustment of conveyor belt tension

[0057] Automatic adjustment trigger

[0058] When the central integrated controller 30 determines that the tension of the conveyor belt 5 needs to be adjusted based on the data of the speed sensor, for example, when it detects that the conveyor belt 5 shows signs of slipping or the conveyor belt 5 becomes loose due to long-term operation, the central integrated controller 30 sends a command to the adjustment motor 6.

[0059] Adjustment process

[0060] The regulating motor 6 starts and rotates forward or reverse according to the instruction of the central integrated controller 30. The regulating motor 6 drives the screw 9 to rotate. Since the nut 8 is fixed to the end of the connecting seat 7, the screw 9 slides horizontally in the connecting seat 7. The slide 2 moves smoothly under the guidance of the guide slide bar 10, thereby changing the position of the shaft frame 1 and adjusting the tension of the conveyor belt 5. During the adjustment process, the central integrated controller 30 continuously monitors the speed changes of the friction roller 4 and the conveyor belt 5. When the speed ratio returns to the normal range, the operation of the regulating motor 6 is stopped, and the automatic adjustment process of the tension of the conveyor belt 5 is completed.

[0061] Through the above specific implementation methods, the anti-skid device for the coal conveyor belt of the power plant can effectively realize the functions of coal transportation, conveyor belt cleaning, speed monitoring and tension adjustment, so as to ensure the efficient and stable operation of the coal transportation work of the power plant.

In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.
