Description

Technical Field

[0001] This invention relates to the field of maintenance and management technology for mining transportation equipment, specifically to a method and system for the operation and maintenance of a buried scraper conveyor. Background Technology

[0002] Submerged scraper conveyors are widely used in mining, coal mining, and steel industries, primarily for material transport. This equipment typically operates under high loads and harsh environments for extended periods; therefore, its reliability and stability are crucial to the entire production system. The operation of a submerged scraper conveyor relies on several key components, including the reducer, transmission system, and scraper chain, and the lubrication status of these components directly affects the equipment's operating efficiency and service life.

[0003] With the acceleration of industrialization, traditional buried scraper conveyors typically rely on manual inspection and periodic oiling for lubrication management. To ensure the normal operation of buried scraper conveyors, the equipment's lubrication system needs regular inspection and maintenance to ensure that the lubricating oil is in the appropriate quantity and quality.

[0004] The limitations of existing technologies include at least the following problems. First, existing technologies typically rely on fixed-cycle lubrication methods, and the lubrication volume is not adjusted according to the real-time status of the equipment. Equipment has different lubrication requirements at different operating stages, such as load changes and temperature fluctuations, and traditional lubrication methods cannot respond to these changes in real time, resulting in a constant lubrication volume.

[0005] This fixed lubrication method can easily lead to either excessive or insufficient lubrication. If the equipment is lubricated at a fixed amount under high load or high temperature, there may be too much lubricating oil, wasting resources and potentially causing overheating. Conversely, if the equipment is under heavy load but is not lubricated in time, it may result in poor lubrication, accelerated wear, or even malfunction and shutdown. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a method and system for the operation and maintenance of buried scraper conveyors, which solves the problem that existing technologies have difficulty in dynamically adjusting the oil injection volume according to the actual operating status of the equipment during the oil injection process.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a method for the operation and maintenance of a buried scraper conveyor, comprising the following steps: during the operation of the buried scraper conveyor, collecting a data set of the operating status of the target lubrication points; analyzing the lubrication demand index of the target lubrication points based on the data set of operating status; determining whether the lubrication points require oil injection based on the lubrication demand index; when the target lubrication points require oil injection, analyzing the oil injection correction factor of the lubrication points based on the corresponding data set of operating status; obtaining the standard oil injection amount of the lubrication points based on the QR code recognition result of the buried scraper conveyor, and analyzing the target oil injection amount of the target lubrication points in conjunction with the corresponding oil injection correction factor, and controlling the lubrication oil injection module to perform a quantitative oil injection operation.

[0008] Furthermore, the operational status dataset includes current operational data and historical lubrication record data.

[0009] Furthermore, the current operating data includes the current running time, current load power, current temperature value, current operating attitude tilt angle, and current equipment vibration intensity. The historical lubrication record data includes the cumulative running time of the previous lubrication and the previous lubrication amount.

[0010] Further, the specific steps for analyzing the lubrication demand index of the target lubrication part are as follows: read the current running time, current temperature value, and current equipment vibration intensity of the target lubrication part, and perform standardization processing; combine the standardized current running time, current temperature value, and current equipment vibration intensity of the target lubrication part with the corresponding current load power and current operating attitude tilt angle for comprehensive analysis to obtain the lubrication demand index of the target lubrication part.

[0011] Furthermore, the specific formula for calculating the lubrication demand index of the target lubrication point is as follows: ; in, , , The parameters are, in order: lubrication demand index of the target lubrication point, current load power, and current operating attitude tilt angle. , , The following are, in order, the current runtime, current temperature, and current equipment vibration intensity of the target lubrication point after standardization. It is a natural constant. , , , , The coefficients are, in order, runtime coefficient, load power coefficient, temperature coefficient, vibration intensity coefficient, and attitude tilt angle coefficient stored in the database.

[0012] Furthermore, based on the lubrication demand index, the specific steps to determine whether the lubrication part needs to be lubricated are as follows: match the lubrication demand index of the target lubrication part with the preset lubrication demand range; when the lubrication demand index is within the preset lubrication demand range, it is determined that the lubrication part needs to be lubricated.

[0013] Further, the specific steps for analyzing the lubrication correction factor of the target lubrication part are as follows: read the current running time, current load power, current temperature value, cumulative running time of the previous lubrication, and previous lubrication amount of the target lubrication part; perform a comprehensive analysis on the current running time, current load power, current temperature value, cumulative running time of the previous lubrication, and previous lubrication amount of the target lubrication part to obtain the lubrication correction factor of the target lubrication part.

[0014] Furthermore, the specific steps for analyzing the target lubrication point are as follows: multiply the standard lubrication point with the lubrication correction factor to obtain the lubrication correction index of the target lubrication point; based on the lubrication correction index, determine the target lubrication point.

[0015] Furthermore, the specific steps for determining the target oil injection amount for the target lubrication part are as follows: the oil injection correction index of the target lubrication part is matched and analyzed with several preset oil injection intervals, and each oil injection interval corresponds to an oil injection correction amount; the oil injection correction amount corresponding to the oil injection correction index being within a preset oil injection interval is regarded as the target oil injection amount for the target lubrication part.

[0016] A maintenance and operation system for a buried scraper conveyor includes: an operation status data acquisition unit for acquiring operation status datasets of target lubrication points during the operation of the buried scraper conveyor; a lubrication demand analysis unit for analyzing the lubrication demand index of the target lubrication points based on the operation status dataset; an oil injection demand judgment unit for determining whether the lubrication point needs to be oiled based on the lubrication demand index; an oil injection correction factor analysis unit for analyzing the oil injection correction factor of the lubrication point based on the corresponding operation status dataset when the target lubrication point needs to be oiled; a standard oil injection quantity acquisition unit for acquiring the standard oil injection quantity of the lubrication point based on the QR code recognition result of the buried scraper conveyor; and an oil injection control unit for combining the standard oil injection quantity of the lubrication point with the corresponding oil injection correction factor to analyze the target oil injection quantity of the target lubrication point and control the lubrication oil injection module to perform a quantitative oil injection operation.

[0017] The present invention has the following beneficial effects:

[0018] (1) The operation and maintenance method of the buried scraper conveyor can accurately analyze the actual lubrication demand of the target lubrication parts by collecting equipment operating status data in real time and combining it with the calculation of lubrication demand index. This analysis not only dynamically adjusts the lubrication demand according to the real-time working status of the equipment, but also takes into account multiple factors such as equipment load, operating environment and historical lubrication records. This avoids the defects of relying solely on fixed oiling cycles in traditional technology. Traditional oiling methods often do not make flexible adjustments for specific operating conditions, which may lead to excessive or insufficient oiling, affecting the operating efficiency and service life of the equipment. Through the lubrication demand analysis of this invention, the equipment can judge the consumption of lubricating oil according to real-time data, ensuring that each lubrication part receives appropriate lubrication at the right time. This dynamic adjustment can effectively reduce oil waste, avoid insufficient or excessive lubrication, help improve the stability of the equipment, reduce failures caused by insufficient lubrication, and extend the service life of the equipment.

[0019] (2) The operation and maintenance method of the buried scraper conveyor, by combining the oil injection correction factor and the standard oil injection amount, further improves the accuracy of oil injection. Traditional oil injection methods mostly rely on periodic time intervals for oil injection, and often do not consider the actual lubrication needs of the equipment under different working conditions. The standardization of oil injection often cannot adapt to the changes in actual operating conditions, resulting in an imbalance in the equipment lubrication system, and even affecting the operating efficiency and stability of the equipment. Through barcode identification and calculation of the oil injection correction factor, the oil injection amount can be dynamically adjusted according to the real-time operating status of the equipment and historical oil injection records. For example, when the equipment load is heavy, the system will automatically increase the oil injection amount; when the equipment load is light or the temperature is high, the system will reduce the oil injection amount. This intelligent control ensures that the use of lubricating oil is more efficient, avoids oil waste, and also ensures the stable operation of the equipment. Precise control of the oil injection amount can not only reduce the risk of over-lubrication of the equipment, but also reduce the waste of lubricating oil and reduce the maintenance cost of the enterprise.

[0020] (3) The operation and maintenance system of the buried scraper conveyor significantly reduces the need for manual intervention and improves the automation and intelligence level of the entire maintenance process through automated and intelligent data acquisition of operating status, lubrication demand analysis, oil injection control and correction factor analysis. Existing technologies often rely on manual operation, and maintenance personnel need to manually adjust the oil injection amount and manage lubrication according to the actual condition of the equipment. This not only increases the risk of human error, but also makes the equipment maintenance process more cumbersome and inefficient. By introducing an automatic data acquisition unit to monitor the equipment operating status in real time, and combining the lubrication demand calculation and oil injection correction factor dynamic adjustment of the data analysis unit, the system can effectively improve the equipment maintenance process. The system ensures precise control of the lubrication volume without manual intervention. This automated process not only improves the accuracy of lubrication operations but also ensures that each lubrication point receives proper and timely lubrication, avoiding the potential problems of over-reliance on human judgment. At the same time, the QR code recognition system provides automated data transmission and recording functions for the equipment, uploading all maintenance and lubrication data to the data center in real time, ensuring the recording and subsequent traceability of each operation. This intelligent management method reduces errors caused by manual operation, improves maintenance efficiency, and reduces equipment maintenance costs, providing enterprises with a more efficient, intelligent, and low-risk maintenance solution.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] Figure 1 This is a flowchart of an operation and maintenance method for a buried scraper conveyor according to the present invention.

[0023] Figure 2 This is a flowchart illustrating the specific steps involved in analyzing the lubrication demand index of the target lubrication point in a method for operating and maintaining a buried scraper conveyor according to the present invention.

[0024] Figure 3 This is a block diagram of the operation and maintenance system of a buried scraper conveyor according to the present invention. Detailed Implementation

[0025] Please see Figure 1 This invention provides a technical solution: a method for the operation and maintenance of a buried scraper conveyor, comprising the following steps:

[0026] QR codes are installed at the target lubrication points of the buried scraper conveyor. The QR codes record basic equipment data including equipment tag number, model, equipment length, equipment power, reducer lubricant type and quantity, scraper chain type, bearing seat grease type and quantity, reducer type, and transmission chain type.

[0027] During the operation of the buried scraper conveyor, a data set of the operating status of the target lubrication parts is collected. The data set includes operating parameters such as the running time, load power, temperature value, vibration intensity, and attitude tilt angle of the target lubrication parts.

[0028] Based on the operational status dataset, the lubrication demand index of the target lubrication point is analyzed. The lubrication demand index is used to measure the degree of lubricant consumption and determine whether the target lubrication point needs to be lubricated.

[0029] Determine whether the target lubrication point needs to be lubricated based on the lubrication demand index. If the result indicates that lubrication is required, proceed to the next step.

[0030] When an oil injection operation is required at a target lubrication point, an oil injection correction factor is analyzed based on the historical lubrication record dataset of the target lubrication point (including the cumulative duration of the previous oil injection and the previous oil injection volume). The oil injection correction factor considers the equipment's historical lubrication records, the equipment's current operating status, and environmental factors to determine the adjustment ratio for the oil injection volume.

[0031] The standard oil injection amount for the target lubrication point is obtained based on the QR code recognition result of the buried scraper conveyor. The basic equipment data and oil injection standards recorded in the QR code provide a basis for the oil injection amount.

[0032] Based on the standard lubrication amount and lubrication correction factor of the target lubrication point, the target lubrication amount of the target lubrication point is determined.

[0033] The lubricating oil injection module performs quantitative oil injection operations. This module includes a lubricating oil injection chamber and a grease injection chamber. The module automatically adjusts the injection volume according to the target amount to ensure injection accuracy. An indicator light system is installed on the module; the indicator lights illuminate based on the data scanned by the barcode scanner, indicating whether oil injection is needed and controlling the injection process.

[0034] After the oil filling operation is completed, the system will display the oil volume on the touch screen to ensure that the oil volume meets the standard requirements, and will monitor the oil volume in real time through a miniature oil supply motor and metering device. When the oil volume reaches the preset standard, the motor stops working and automatically sends feedback to the data center to record the oil filling data.

[0035] After completing each maintenance task, the operator confirms and signs via touchscreen to ensure the traceability and compliance of the maintenance process. During the maintenance process, the operator completes the maintenance work on each component one by one and confirms the maintenance progress according to the task list.

[0036] During maintenance, lifting equipment is used to move the individual chain bins. The scraper chain bins are custom-made according to the chain specifications and length; the chain direction is strictly controlled during installation to prevent reverse installation. The chain bins are designed for recycling and reuse, used for storing and transporting chains, ensuring convenience and safety during chain replacement.

[0037] After the entire maintenance process is completed, all auxiliary equipment and tools will be stored in the maintenance platform. The platform will then transmit the maintenance data back to the data center, generate a maintenance report, and print and sign it for confirmation. The data center records every task performed during the maintenance process, guiding the next maintenance time and content, and pushes notification messages to the management system to ensure the long-term stable operation of the equipment.

[0038] The operational status dataset includes current operational data and historical lubrication records.

[0039] Current operating data includes current running time, current load power, current temperature value, current operating attitude tilt angle, and current equipment vibration intensity. Historical lubrication record data includes the cumulative running time of the previous lubrication and the previous lubrication amount.

[0040] The current running time refers to the cumulative running time of the lubricated part since the last lubrication. It can be obtained through the equipment's running time recording system or timer, usually in hours (h), reflecting the rate of oil consumption of the lubricated part during operation.

[0041] The current load power indicates the load intensity of the lubricated part during operation. It can be measured in real time by a power sensor, usually calculated from the current and voltage data of the equipment, and the unit is kilowatt (kW) or watt (W). The greater the load, the faster the lubricating oil is consumed.

[0042] The current temperature value refers to the operating temperature of the lubricated part during operation. This temperature can be measured in real time using a temperature sensor (such as a thermocouple or RTD sensor), and the unit is degrees Celsius (°C) or Kelvin (K). When the temperature is too high, the lubricating oil evaporates faster, thus requiring more lubricating oil.

[0043] The current operating tilt angle represents the angle of inclination of the lubricated part relative to the horizontal plane during equipment operation. This angle can be measured using a tilt sensor or accelerometer installed on the equipment, and is expressed in degrees (°) or radians (rad). A large tilt angle can lead to uneven distribution of lubricating oil, affecting lubrication effectiveness.

[0044] The current equipment vibration intensity refers to the vibration intensity of the lubricated part during operation. Vibration intensity can be measured in real time using an accelerometer or vibration analyzer, and the unit is meters per second squared (m / s²). Excessive vibration will damage the stability of the oil film, leading to a decrease in lubrication effect.

[0045] The cumulative operating time since the last lubrication refers to the total operating time of the lubricated part since the last lubrication. This value can be obtained through the equipment's operating time recording system or lubrication record system, and is expressed in hours (h) or other appropriate time units, reflecting the operating status and oil consumption of the lubricated part.

[0046] The previous lubrication volume refers to the amount of lubricating oil added during the last lubrication. This value can be measured by the flow meter or lubrication pump of the lubrication equipment, and the unit is usually milliliters (mL) or liters (L). It directly affects the correction amount for the current lubrication.

[0047] Specifically, such as Figure 2 As shown, the specific steps for analyzing the lubrication demand index of the target lubrication part are as follows: Read the current running time, current temperature value, and current equipment vibration intensity of the target lubrication part, and perform standardization processing (i.e., unit removal); Combine the standardized current running time, current temperature value, and current equipment vibration intensity of the target lubrication part with the corresponding current load power and current operating attitude tilt angle for comprehensive analysis to obtain the lubrication demand index of the target lubrication part.

[0048] The specific formula for calculating the lubrication demand index of the target lubrication point is as follows: ; in, , , The parameters are, in order: lubrication demand index of the target lubrication point, current load power, and current operating attitude tilt angle. , , The following are, in order, the current runtime, current temperature, and current equipment vibration intensity of the target lubrication point after standardization. This is a natural constant, and in this embodiment, it is taken as 2.71. , , , , The coefficients are, in order, runtime coefficient, load power coefficient, temperature coefficient, vibration intensity coefficient, and attitude tilt angle coefficient stored in the database, and in this embodiment, they are respectively taken as 0.1, 0.15, 0.2, 0.1, and 0.05.

[0049] In this implementation plan, by comprehensively considering multiple parameters during the operation of the scraper conveyor, the lubrication demand index is accurately analyzed, thereby achieving more intelligent lubrication management. Traditional lubrication management methods often rely on fixed cycles or standard oil injection volumes, failing to consider the actual lubrication needs of the equipment under different loads, temperatures, and vibrations. This real-time data-based analysis method can dynamically adjust the amount of lubricating oil injected according to data such as the equipment's running time, load power, temperature, vibration intensity, and tilt angle, avoiding the problems of over- or under-injection in traditional technologies. Through standardized processing and the introduction of natural constant coefficients, the lubrication needs of the equipment under different operating conditions can be calculated more accurately. The system performs reasonable analysis based on the operating status dataset (such as load power, vibration intensity, etc.) to ensure that each oil injection is precisely adjusted according to the actual needs of the equipment, thereby improving the operating efficiency and stability of the equipment. In addition, the implementation of this method avoids the defects of over-reliance on manual operation, greatly reducing errors caused by human judgment and unnecessary maintenance costs.

[0050] Specifically, based on the lubrication demand index, the specific steps to determine whether the lubrication part needs to be lubricated are as follows: match the lubrication demand index of the target lubrication part with the preset lubrication demand range; when the lubrication demand index is within the preset lubrication demand range, it is determined that the lubrication part needs to be lubricated.

[0051] In this implementation scheme, by matching the lubrication demand index with a preset range, the system can intelligently determine whether lubrication is needed based on the actual operating status of the equipment. This avoids the problems of over- or under-lubrication caused by improper manual operation or fixed-cycle lubrication in traditional methods. Traditional lubrication management methods often fail to adjust in real time according to the equipment status, leading to lubrication waste or insufficient lubrication, which affects the normal operation of the equipment. Through the intelligent matching analysis of this invention, when the lubrication demand index is within a reasonable range, the system automatically decides whether lubrication is needed, ensuring that each lubrication operation can accurately meet the lubrication needs of the equipment. This not only improves the efficiency of lubrication use and reduces waste, but also avoids equipment wear and failure due to insufficient lubrication, thus extending the service life of the equipment. In addition, the intelligent determination based on the lubrication demand index reduces the intervention of manual judgment, improves the efficiency of maintenance and lubrication operations, and the automated control and feedback mechanism not only ensures the accuracy of lubrication, but also simplifies the maintenance process, reduces the maintenance cost of the equipment, and provides a strong guarantee for the long-term stable operation of the equipment. Through this intelligent method, equipment maintenance management becomes more efficient and reliable.

[0052] Specifically, the steps for analyzing the lubrication correction factor of the target lubrication part are as follows: read the current running time, current load power, current temperature value, cumulative running time of the previous lubrication, and previous lubrication amount of the target lubrication part; perform a comprehensive analysis on the current running time, current load power, current temperature value, cumulative running time of the previous lubrication, and previous lubrication amount of the target lubrication part to obtain the lubrication correction factor of the target lubrication part.

[0053] The specific formula for calculating the lubrication correction factor for the target lubrication point is as follows: ; in, , , , , , The parameters are, in order: lubrication correction factor for the target lubrication point, current temperature, current load power, previous lubrication amount, current running time, and cumulative running time since the previous lubrication. , , , The values ​​are, in order, the temperature correction factor, the load correction factor, the previous oil filling correction factor, and the running time correction factor stored in the database, and in this embodiment, they are respectively taken as 0.3, 0.1, 0.05, and 0.2.

[0054] In this implementation scheme, dynamic adjustment of the lubrication amount is achieved through comprehensive analysis of the lubrication correction factor, ensuring more precise lubrication of the equipment. Traditional lubrication methods typically rely on a fixed lubrication amount, ignoring the actual needs of the equipment under different operating conditions, which may lead to excessive or insufficient lubrication, affecting the equipment's operating performance. Through the lubrication correction factor analysis of this invention, the system can dynamically calculate the required lubrication amount based on the equipment's real-time operating data (such as temperature, load, and running time) and the previous lubrication situation, thereby achieving more efficient and precise lubrication management. Specifically, factors such as temperature, load, and running time directly affect the equipment's lubrication requirements. By introducing a correction coefficient, optimization adjustments can be made for different equipment operating conditions. When the temperature is too high or the load is heavy, the lubrication requirement is greater; when too much or too little lubrication is applied, the system will automatically correct based on historical lubrication amounts. This personalized adjustment not only avoids the problem of blind lubrication in traditional technologies but also reduces lubrication waste, improves equipment operating efficiency, and lowers the failure rate.

[0055] Specifically, the steps for analyzing the target lubrication point are as follows: multiply the standard lubrication point with the lubrication correction factor to obtain the lubrication correction index of the target lubrication point; and determine the target lubrication point based on the lubrication correction index.

[0056] In this implementation scheme, the precise calculation of the target lubrication amount is achieved through dynamic adjustment of the lubrication correction factor, avoiding the blindness of traditional lubrication methods. Traditional lubrication methods usually rely on a fixed lubrication amount, ignoring the real-time status of the equipment and historical lubrication data, which may lead to over- or under-lubrication. However, this invention introduces the lubrication correction factor, combined with the equipment's standard lubrication amount, to precisely adjust the actual lubrication amount of each lubrication point, making the lubrication operation more in line with the actual needs of the equipment. Specifically, by multiplying the standard lubrication amount by the lubrication correction factor, the system can dynamically calculate the lubrication correction index based on factors such as the equipment's operating status, temperature, and load. This process ensures that the amount of lubricating oil can be adjusted in real time, rather than being injected at a fixed predetermined amount, avoiding over- or under-lubrication under different operating conditions. This not only improves lubrication efficiency but also reduces oil waste and reduces equipment failures caused by improper lubrication.

[0057] Specifically, the steps for determining the target oil injection amount for the target lubrication point are as follows: the oil injection correction index of the target lubrication point is matched and analyzed with several preset oil injection intervals, and each oil injection interval corresponds to an oil injection correction amount; the oil injection correction amount corresponding to the oil injection correction index being within a preset oil injection interval is regarded as the target oil injection amount for the target lubrication point.

[0058] In this implementation scheme, precise adjustment of the lubrication amount to the target lubrication point is achieved through matching analysis of the lubrication correction index and the preset lubrication range. Traditional lubrication methods often operate based on fixed time intervals or lubrication amounts, which cannot take into account real-time changes during equipment operation and may lead to over- or under-lubrication. However, this invention analyzes the equipment's lubrication correction index and combines it with preset lubrication ranges to dynamically adjust the lubrication amount according to the actual operating status of the equipment, ensuring the precise operation of the lubrication system. Specifically, the system calculates the lubrication correction index based on the equipment's operating data and matches it with multiple preset lubrication ranges. Each lubrication range represents a specific lubrication correction amount. The system determines the corresponding correction amount based on the range in which the lubrication correction index falls. In this way, when the operating conditions of the equipment change, the lubrication amount can also be intelligently adjusted accordingly.
