[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0029] Embodiment one: please refer to Figure 1 - Figure 4As shown, the embodiment is a kind of rotary kiln wheel belt deflection measurement method and system based on laser, including the following steps:
[0030] S1: the parameter collection of laser measuring equipment deployed around the rotary kiln wheel belt, the laser measuring equipment can be measured remotely and non-contact by computer Bluetooth or network wireless connection control according to field practice, combined with optical measurement and control components, not only greatly improves the safety of measurement, so that the measurement personnel do not need to approach the high-temperature and dangerous rotary kiln equipment, reduces the potential safety risk, and due to the non-contact measurement characteristics, the precision deviation that the equipment may generate due to contact with high temperature is avoided, the collected parameters are compared with the pre-stored threshold to generate wheel belt abnormal state signal and sustainable accessory signal and sent to S2 and S3 steps;The real-time monitoring module continuously monitors the collected data of the rotary kiln wheel belt in use as follows:
[0031] S11: obtain the belt rotation visible parameters of the rotary kiln wheel belt during operation, the belt rotation visible parameters are represented as the parameters that can be detected during the operation of the rotary kiln wheel belt body, mark the running time from the starting time of the rotary kiln wheel belt operation to the present time as the supervision period, divide the supervision period into several groups of period nodes, and substitute the belt rotation visible parameters into the corresponding period nodes, so as to mark the collected data with time for subsequent retrieval and identification;The belt rotation visible parameters include wheel belt width status data and accessory status data, the wheel belt width status data can be represented as the overhead transverse dimension and side view width and height dimension of the rotary kiln wheel belt in operation measured by the laser measuring equipment, such as Figure 4 As shown, the accessory status data can be represented as kiln cylinder, transmission synchronous wheel belt, supporting roller and other accessories, which are used to connect and drive the rotary kiln wheel belt and the rotary kiln body;
[0032] S12: compare the pre-stored new wheel belt loading set threshold and accessory loading threshold with the wheel belt width status data and accessory status data, it should be noted that the new wheel belt loading set threshold can be represented as the relevant numerical values on the factory label of the new and undamaged wheel belt replaced during the assembly or maintenance of the rotary kiln, and the accessory loading threshold represents the gear, wear and surface state data record after the assembly or maintenance of the rotary kiln;
[0033] S13: if the wheel belt width status data is within the fluctuation range of the new wheel belt loading set threshold, and the accessory status data is within the accessory loading threshold range, no signal is generated, which means that the wheel belt data collected in the compared period node meets the predetermined range, so it does not need to be adjusted, and it can still maintain the present situation and continue to run stably;
[0034] S14: If the belt width current data is not located in the fluctuation range of the new belt loading set threshold value, and the accessory current data is not located in the accessory loading threshold value range, a belt abnormal state signal is generated. When the real-time monitoring module receives the belt abnormal state signal, it immediately triggers the pre-stored adjustment scheme 001. Scheme 001 or other numbered schemes are constructed based on historical records of similar faults and maintenance and adjustment in previous operation supervision cycles, combined with regular maintenance and adjustment plans for the area with belt width and accessory abnormalities. The real-time monitoring module analyzes the belt abnormal state signal data to determine which type of belt width or accessory is abnormal. According to this, the relevant processing steps recorded in scheme 001 are matched, the regular processing of steps that do not exist is simplified, the abnormality is accurately located and processed faster and more efficiently, and the overall processing efficiency is greatly improved.
[0035] S15: Retrieve the analysis data of the generated belt abnormal state signal and the accessory loading threshold value for comparison processing from the latest accessory operation and maintenance records in the supervision cycle , accessory operation and maintenance records representing the existence of rotary kiln related to the belt and the related accessories in this supervision cycle. Among them, i represents a natural number greater than zero. The accessory loading threshold value and the same type of data in the accessory operation and maintenance records are normalized to eliminate dimensional differences and obtain several types of standard values. The difference between the maximum and minimum values of the several types of standard values is marked as a fault tolerance coefficient. The standard mean value is obtained by dividing the sum of the several types of standard values by the number of the several types of standard values.
[0036] S16: If the accessory current data in the belt abnormal state signal is close to the standard mean value and within the ± fault tolerance coefficient range, a sustainable accessory signal is generated. When the real-time monitoring module receives the sustainable accessory signal, it immediately generates "rotary kiln serial number # 931 / belt abnormality / accessory detection normal / belt depth detection" style text information and sends it to the intelligent device of the on-duty supervisor for prompt display, to help the on-duty supervisor quickly locate the abnormal area of the rotary kiln belt operation. Among them, the sustainable accessory signal represents that the related accessories for matching the belt are normal, and the belt abnormal state signal represents that the belt body has an abnormality. It should be noted that the rotary kiln serial number # 931 represents the rotary kiln with a serial number of 931 marked in the factory area.
[0037] S17: If the accessory status data in the belt abnormal state signal deviates from the standard mean value and exceeds the ± tolerance coefficient range, an operation and maintenance instruction signal is generated. When the real-time monitoring module receives the operation and maintenance instruction signal, it immediately generates "rotary kiln serial number #931 / belt abnormality / accessory abnormality / accessory depth detection" style text information and accessory status data and sends them to the intelligent device of the on-duty supervisor, which is used to directly indicate that the "belt abnormal state signal" is caused by an accessory, and trigger the pre-stored scheme 002. Scheme 002 contains examples of obvious manifestations of accessory abnormalities. The supervisor's intelligent device retrieves the accessory status data and compares it with the examples in scheme 002. The examples that have differences are marked with part of the data in the accessory status data, which facilitates the supervisor and accompanying maintenance personnel to quickly handle the different accessories. Embodiment two
[0038] S2: After receiving the generated signal, several groups of old and new environment parameters are retrieved to construct a rectangular coordinate system, and the corresponding fluctuation curve and span value are intercepted to analyze the proportion with the corresponding threshold value. The belt regular wear signal and the belt abnormal wear signal are generated and sent to the S3 step. The joint analysis process of the belt data runout analysis module after receiving the belt abnormal state signal and the sustainable accessory signal is as follows:
[0039] S21: Obtain the new environment parameters around the rotary kiln belt and several groups of old environment parameters that are inversely calculated from the past, with the period node where the new environment parameters are constructed as the starting point, and the representative parameters of different parameters in each historical period node are normalized and averaged to obtain a balanced representative parameter in the same period node. The period node is used to construct the X axis, and the temperature increasing order is used to construct the Y axis to construct a rectangular coordinate system, as shown in Figure 2 It should be noted that ○ represents the new environment parameter, △ represents the representative parameter of the old environment parameter, and □ represents the temperature control interval threshold range;
[0040] S22: Draw the fluctuation curve of several groups of old and new environment parameters by drawing points and connecting lines. Record the length of the adjacent fluctuation curve as the span value. The span value represents the fluctuation difference of the environment parameters in adjacent period nodes. The greater the difference, the more abnormal the rotary kiln is during operation, resulting in a large difference in temperature in the detection area. This not only causes a sudden change in temperature difference in the belt environment, but also causes the belt to melt or the material to become brittle under the condition of sudden temperature change, thereby causing belt use abnormalities and causing runout and other phenomena. Retrieve the pre-stored rotary kiln belt running temperature control interval threshold range and draw it on the rectangular coordinate system. Mark the parts that exceed the upper limit of the temperature control curve threshold as several old high temperature points and new high temperature points The part below the lower limit of the temperature control curve threshold is marked as a number of old low temperature points in turn and new low temperature points .
[0041] S231: retrieve the pre-stored preset high temperature proportion threshold, preset low temperature proportion threshold and preset span threshold, and count the total number of a number of old high temperature points , new high temperature points , a number of old low temperature points and new low temperature points for comprehensive comparison and analysis
[0042] S232: when the total number of new high temperature points is less than the preset high temperature proportion threshold in the total number of a number of old high temperature points , the total number of new low temperature points is less than the preset low temperature proportion threshold in the total number of a number of old low temperature points , and the span value of the new environment parameter is less than the preset span threshold, a regular wear signal of the tire belt is generated. It should be noted that the regular wear signal of the tire belt indicates that the tire belt wear is not caused by the change of the ambient temperature around the operation environment, but the tire belt body meets the regular wear range during the load operation on the rotary kiln. When the regular wear signal of the tire belt is sent to the real-time monitoring module, the scheme 003 is triggered. The maintenance replacement instruction is pre-stored in the scheme 003. The related data of the tire belt regular wear signal are sent to the intelligent device of the on-duty supervisor, so that the supervisor can quickly forward the maintenance replacement instruction and the related data to the maintenance personnel, replace the suitable tire belt, and match and adjust the replaced tire belt and other groups of tire belts according to the related data
[0043] S233: when the total number of new high temperature points is greater than the preset high temperature proportion threshold in the total number of a number of old high temperature points , the total number of new low temperature points is greater than the preset low temperature proportion threshold in the total number of a number of old low temperature points greater than a preset low-temperature proportion threshold, and the span value of the new environment parameter is greater than a preset span threshold, a tire belt abnormal wear signal is generated; it should be noted that the group of tire belts is caused by the change of the ambient temperature difference around the tire belts, resulting in unstable use load environment, so that the running environment of the tire belts on the rotary kiln is far below the standard environment, thereby causing the tire belt to deviate, after the real-time monitoring module receives the tire belt abnormal wear signal, immediately marks the related data of the tire belt abnormal wear signal, generates the "rotary kiln serial number # 931 / tire belt abnormal / loop difference abnormal / kiln body load adjustment / tire belt replacement / related data" style text information and triggers scheme 004, and sends the generated text and scheme 004 to the intelligent devices of the on-duty supervisors, the related data is represented as the comparison data of the generated tire belt abnormal wear signal, so that the rotary kiln equipment operation and maintenance personnel / supervisors can process according to the related data and the matched examples in scheme 004, complete the deviation supervision, real-time dynamic adjustment and maintenance of the rotary kiln tire belts. Embodiment three
[0044] S3: Obtain the hydraulic wheel stop working pressure dispersion rate of several groups and the conventional running efficiency to build a floating curve, and combine the received multiple groups of signal linkage analysis processing, which is used for rotary kiln tire belt deviation prediction and control processing, the conventional running efficiency represents the efficiency data of the rotary kiln tire under conventional state continuous running, and the prediction evaluation module in the process of predicting the rotary kiln tire belt deviation is as follows:
[0045] S31: Obtain the hydraulic wheel stop working pressure dispersion rate in several cycle nodes by backtracking to the present time , the hydraulic wheel stop working pressure dispersion rate is represented as the proportion of the actual working pressure of the hydraulic wheel stop to the standard working pressure in several cycle nodes, wherein the standard working pressure is the pressure size of the hydraulic wheel stop under the rated power working, and the cycle node is taken as the horizontal axis, and the pre-stored data of the rotary kiln tire equipment under the latest state is taken as the vertical axis, which is the data of the rotary kiln under the initial assembly, under the conventional load running condition, the efficiency of generating processing products, and the hydraulic wheel stop working pressure dispersion rate is plotted in turn to draw the trend floating curve, and whether the tire belt abnormal state signal, operation and maintenance instruction signal or tire belt abnormal wear signal is generated in the cycle node of the present time is combined to predict the future rotary kiln tire belt deviation trend;
[0046] S32: When there is a wheel belt abnormal state signal, an operation and maintenance instruction signal or a wheel belt abnormal wear signal in the period node of the time up to now, it is judged that the rotary kiln wheel has adjustment, maintenance and other changes in the future, and thus there is uncertainty in the operation of the rotary kiln and the replaced wheel belt in the future. Therefore, it is judged that the group "rotary kiln serial number #931" needs to be adjusted in the future. According to this, the load of the adjacent rotary kiln is adjusted in advance to ensure the processing efficiency.
[0047] S33: When there is no wheel belt abnormal state signal, operation and maintenance instruction signal or wheel belt abnormal wear signal in the period node of the time up to now, it is indicated that the group "rotary kiln serial number #931" can continue normal operation load and complete the processing efficiency, without the need for advance change and adjustment.
[0048] In combination with example one, example two and example three, the hydraulic wheel blocking working pressure dispersion rate The linkage analysis of the floating curve and multiple signals can predict the wheel belt deviation trend in advance, and trigger the preset scheme of load regulation, part replacement, etc. in a targeted manner. The faults caused by wheel belt deviation overrun, such as roller shaft wear and kiln body center line deviation, are effectively avoided, the non-scheduled downtime is reduced, the equipment stability is improved, the equipment maintenance cost and production energy consumption are significantly reduced, and the long-term efficient operation of the rotary kiln is ensured.
