[0018] Figure 1The present invention is a flow chart of the installation and positioning method of the cross-free whole-section assembled angle steel tower.

[0019] Figure 2 The present invention is a flowchart of the installation and positioning system of the cross-free whole-section assembled angle steel tower. DETAILED DESCRIPTION

[0020] The embodiment of the present application realizes the need to consider environmental factors in advance and monitor installation stability in real time for the assembled angle steel tower through the installation and positioning method and system of the whole-section assembled angle steel tower without crossing, which can effectively improve the quality and efficiency of the installation, reduce the risks and uncertainties in the installation process, and achieve accurate installation and positioning.

[0021] The overall idea of ​​the problem in the embodiment of this application is as follows: Before installation, obtain the safe wind speed and direction information for the day and the next few days through meteorological data or weather forecasts, determine the safe range of lifting operations, evaluate the performance of lifting equipment, and understand the possible vibration conditions that may occur during the lifting process, so as to take precautions and control in advance.

[0022] During the lifting process of the angle steel tower, the inclination angle, horizontality, vibration, etc. of the tower body are monitored in real time through sensors or monitoring equipment to ensure stability during the lifting process. After the upper angle steel tower is lifted to the predetermined position, the lower angle steel tower is docked and installed with the upper angle steel tower. The stability also needs to be monitored in real time to ensure that the two parts can be accurately docked and fixed.

[0023] Before the actual hoisting, conduct on-site surveys, clean the installation area, and perform necessary foundation treatment to ensure the stability of the installation foundation. According to the safe wind speed and wind direction information, determine the time and method of hoisting operations, equip appropriate hoisting equipment, and ensure that the hoisting personnel have relevant skills and experience. During the hoisting process, monitor the stability of the tower in real time. If any abnormality is found, stop the hoisting operation immediately and take corresponding safety measures. After the upper angle steel tower is hoisted to the predetermined position, immediately carry out the docking installation of the lower angle steel tower to ensure that the two parts are tightly connected and fixed.

[0024] See also Figure 1The embodiment of the present invention provides a technical solution: a method for installing and positioning a cross-free whole-section assembled angle steel tower, comprising the following steps: obtaining installation and positioning environmental parameters of the cross-free whole-section assembled angle steel tower, wherein the assembly environmental parameters include safe wind speed, wind direction and vibration value of the hoisting equipment; monitoring the stability of the upper section assembled angle steel tower during lifting based on the lifting parameter data obtained by matching, and stopping the lifting if the stability is not satisfied; after the upper section assembled angle steel tower is stably lifted to a predetermined position, monitoring the stability of the docking installation of the upper section assembled angle steel tower and the lower section assembled angle steel tower based on the hanging parameter data obtained by matching, and stopping the hanging if the stability is not satisfied, obtaining a number of stability data at preset time intervals during the lifting and hanging time of the angle steel tower, constructing a lifting stability data set and a hanging stability data set, and performing data analysis on the lifting stability data set and the hanging stability data set to determine the docking hazards; after the upper section assembled angle steel tower is docked with the lower section assembled angle steel tower, and there is no docking hazard, the installation and positioning is completed.

[0025] It should be noted that in the process of obtaining the installation and positioning environmental parameters of the cross-free whole-section assembled angle steel tower, before hoisting, the environmental sensor array (wind speed sensor, vibration sensor, temperature and humidity sensor) is used to monitor the on-site conditions in real time. The system will automatically record the environmental parameters and compare them with the set safety thresholds. If the wind speed exceeds the safety range, the hoisting operation will be automatically stopped; In the process of monitoring the stability of the upper assembled angle steel tower during lifting based on the matched lifting parameter data, during the lifting process, the system matches the preset lifting stability model based on the real-time sensor data (such as vibration sensor data, tower inclination, etc.). If the stability is detected to be lower than the set threshold (such as vibration exceeding the preset value or the inclination angle is too large), the system immediately suspends the lifting action, issues an alarm, and recommends adjusting the lifting angle or speed.

[0026] After the upper prefabricated angle steel tower is stably hoisted to the predetermined position, the stability of the docking installation of the upper prefabricated angle steel tower and the lower prefabricated angle steel tower is monitored based on the matched lower hoisting parameter data. During the docking process, a high-precision laser sensor is used to monitor the docking position and angle changes of the two tower bodies in real time. When the stability does not meet the predetermined requirements, the system automatically adjusts the hoisting path or speeds up to optimize the docking stability, or triggers manual intervention for adjustment when necessary.

[0027] Acquire several stability data at preset time intervals during the lifting and lowering of the angle steel tower, construct the lifting stability data set and the lowering stability data set, and perform data analysis on the lifting stability data set and the lowering stability data set. In the process of judging the docking hidden dangers, the system regularly collects stability data during the lifting and lowering process, and presents the lifting and lowering stability data trend chart on the real-time data analysis platform. When the system detects abnormal fluctuations (such as a sudden increase in vibration or a decrease in stability value), it will automatically trigger an early warning and prompt possible hidden dangers, such as uneven tower stress or equipment failure, and provide emergency measures.

[0028] After the upper assembled angle steel tower and the lower assembled angle steel tower are docked and there are no docking hazards, the installation and positioning process is completed. After the docking is completed, the contact pressure and position accuracy of the two tower bodies are detected by sensors to ensure that there is no misalignment or uneven pressure. The system will automatically generate an installation report, record all environmental parameters, equipment status, operation records and other information during the installation process, and provide a basis for subsequent maintenance and safety inspections. If no hidden dangers are found, the system will automatically confirm that the installation positioning is completed and lift the lifting restrictions.

[0029] This application also includes a multi-level security warning and automatic correction mechanism, operation method: During the entire lifting and docking process, based on real-time monitoring data (such as wind speed, vibration, temperature and humidity, tower stability, etc.), the system will set a multi-level safety warning mechanism, which is divided into three levels: warning, warning and emergency stop. Different levels of warning trigger different response strategies, such as prompting operators to make adjustments when warning, automatically slowing down the lifting speed when warning, and immediately stopping the operation when emergency stop.

[0030] The early warning system is combined with the automatic correction mechanism. When the system triggers an early warning, it automatically evaluates the risk level in combination with the machine learning algorithm, adjusts the operation strategy based on the evaluation results, and automatically makes corrections (such as reducing the lifting speed or suspending the operation) to minimize the risk of human error.

[0031] Specifically, the process of obtaining the assembly environment parameters of the cross-free whole-section prefabricated angle steel tower is as follows: based on the set wind sampling period, the wind sampling of the installation positioning environment of the cross-free whole-section prefabricated angle steel tower is carried out to obtain the wind value; it is determined whether the collected wind value data is less than the set safe wind value, and if so, the collected wind value data is marked as safe wind value data; the safe wind speed is calculated based on the safe wind value data, and the wind direction is obtained.

[0032] First, according to the set wind sampling period, wind sampling is performed in the installation positioning environment to obtain wind value data. Then, it is determined whether the collected wind value data is less than the set safe wind value. If so, the data is marked as safe wind value data. Then, based on the safe wind value data, the safe wind speed is calculated according to a certain weight factor, and the wind direction is obtained.

[0033] Through wind sensors and other devices, the wind in the environment is sampled within the set wind sampling period to obtain a series of wind value data. By comparing the collected wind value data with the set safe wind value, the wind value data within the safe range is identified for subsequent calculations. Based on the identified safe wind value data, combined with the correction factor and weight factor, the safe wind speed is calculated using the given formula. On the basis of obtaining the safe wind speed, the wind direction information can be further obtained so that the influence of wind direction on the installation of the diagonal steel tower can be considered during the installation and positioning process.

[0034] Through real-time monitoring of environmental wind force and judgment of the safety range, it is possible to promptly detect whether there is a wind force condition beyond the safety range, thereby ensuring the safety of the lifting operation. By calculating the safe wind speed based on the safe wind force value and combining it with the wind force value predicted by the meteorological weather, and comprehensively considering multiple factors, the accuracy of the judgment of the actual installation environment is improved, which is beneficial to the accuracy and stability of the installation positioning.

[0035] The calculation formula for safe wind speed is: , where For safe wind speed, is the number of the wind sampling period, , is the total number of wind sampling cycles, is the number of the sampling point in each wind sampling cycle, , is the total number of sampling points in each wind sampling cycle, For the The first wind sampling cycle The safe wind force calculation value in the wind force value data of the sampling points is obtained by wind force sensor detection. The correction factor for wind force detected by the wind sensor, For weather forecast wind speed values, is the weight factor of the safe wind force calculation value, is the weight factor of the meteorological forecast wind value, and .

[0036] The logic of the formula is based on the collected wind data, and the safe wind speed is calculated using correction factors and weight factors. The correction factors in the formula are used to adjust the accuracy of wind sensor detection of wind force, taking into account the possible errors or deviations of wind sensors in actual environments. Weight factors and They are used to weigh the influence of the calculated safe wind force value and the meteorological forecast wind force value in the safe wind speed calculation, ensuring that the importance of the sampling data and the meteorological forecast data are comprehensively considered. The correction factor can correct the possible errors of the wind sensor, while the weight factor can adjust the weights of the wind sampling data and the meteorological forecast data according to the actual situation, thereby improving the accuracy of the safe wind speed calculation.

[0037] Based on the set equipment sampling period, the started hoisting equipment is subjected to vibration detection, vibration data is obtained, and the vibration value of the hoisting equipment is calculated based on the vibration data. The calculation formula for the vibration value of the hoisting equipment is: , where is the vibration value of the lifting equipment, is the number of the device sampling cycle, , is the total number of device sampling cycles, is the number of the sampling point in the sampling cycle of each device, , is the total number of sampling points in the sampling cycle of each device, For the The first sampling period of the device The vibration parameters in the vibration data of the sampling points, is the weight factor of the arithmetic mean, is the weight factor of the harmonic mean, and .

[0038] It should be noted that when the hoisting equipment is started, the hoisting strategy is adjusted in real time. If it is detected that the stability does not meet the standard, it will automatically trigger the hoisting to stop and alarm; The stability during the docking process is dynamically monitored. If the safety standards are not met, the lowering action is suspended.

[0039] In this implementation scheme, first, according to the set equipment sampling period, vibration detection is performed when the lifting equipment is started to obtain vibration data. Then, based on these vibration data, the vibration value of the lifting equipment is calculated according to certain weight factors. The arithmetic mean and harmonic mean are considered in the calculation to comprehensively evaluate the vibration condition of the lifting equipment.

[0040] When the hoisting equipment is started, the vibration of the equipment is detected through vibration sensors and other devices to obtain a series of vibration data, including vibration parameters of different sampling periods and sampling points. Based on the collected vibration data, the arithmetic mean and harmonic mean are calculated respectively, and combined with the weight factor and , calculate the vibration value of the lifting equipment according to the given formula. and The weight factors of the arithmetic mean and the harmonic mean are used to adjust the influence of different calculation methods on the vibration data. By adjusting the values ​​of these two weight factors, various vibration conditions can be balanced to more accurately evaluate the vibration conditions of the lifting equipment.

[0041] Specifically, the lifting parameter data include the lifting parameter swing amplitude value and the lifting parameter swing frequency value of the upper section prefabricated angle steel tower. The matching process of the lifting parameter data is as follows: obtain and record the safe wind speed and the vibration value of the lifting equipment as a lifting data group; compare the lifting data group with each lifting matching data group stored in the matching database to obtain the lifting matching similarity, and the lifting matching data group includes the safe wind speed matching value and the lifting equipment vibration matching value; obtain the lifting parameter data corresponding to the lifting matching data group corresponding to the minimum lifting matching similarity.

[0042] Firstly, the safe wind speed and the vibration value of the lifting equipment are combined into a lifting data group. Then, the lifting data group is compared with each lifting matching data group stored in the matching database, and the lifting matching similarity is calculated. Next, the matching data group with the smallest lifting matching similarity is found, and the corresponding lifting parameter data is obtained therefrom, namely, the lifting parameter swing amplitude value and the lifting parameter swing frequency value of the upper section prefabricated angle steel tower.

[0043] The safe wind speed and hoisting equipment vibration values ​​are used as the lifting data group to reflect the safety status of the current lifting environment and the stability of the lifting equipment. The lifting data group is compared with each lifting matching data group stored in the matching database to calculate the similarity between them. The matching data group includes the safe wind speed matching value and the hoisting equipment vibration matching value.

[0044] Find the matching data group with the smallest lifting matching similarity, which means that the matching data group is most consistent with the current lifting data group. Obtain the lifting parameter data from this matching data group, that is, the lifting parameter swing amplitude value and the lifting parameter swing frequency value of the upper assembled angle steel tower, which are used to guide the actual lifting operation.

[0045] According to the current safe wind speed and vibration value of the hoisting equipment, the most suitable lifting parameter data can be matched, which can provide personalized guidance and reference for hoisting operations and improve the accuracy and safety of hoisting. The matching process can provide real-time feedback based on the current environmental conditions and the status of the hoisting equipment to ensure that the hoisting operation is always carried out under safe and stable conditions.

[0046] The calculation formula for lifting matching similarity is: ; In the formula, To match the similarity of lifting, For safe wind speed, is the safe wind speed matching value, is the vibration value of the lifting equipment, is the vibration matching value of the hoisting equipment, is the wind speed lifting weight factor, is the equipment vibration lifting weight factor, and .

[0047] In this implementation, the formula takes into account the difference between the safe wind speed and the vibration value of the lifting equipment, as well as the distance between them and the matching value. The distance value is finally mapped to the lifting matching similarity after a series of transformations and calculations.

[0048] The lifting matching similarity is calculated using the given formula. The formula includes the matching items of safe wind speed and lifting equipment vibration value, as well as the corresponding weight factors. and , which is used to adjust their influence on the similarity. The formula comprehensively considers the matching of safe wind speed and hoisting equipment vibration value, as well as their influence on the lifting operation. By considering these two factors and calculating the lifting matching similarity based on the distance between them and the matching value, the suitability of the lifting operation can be more comprehensively evaluated. Weight factor and It can be adjusted according to actual conditions so as to flexibly adjust the influence of safe wind speed and hoisting equipment vibration value on the lifting matching similarity according to different engineering environments and hoisting requirements. Specifically, the lifting parameter data include the lifting parameter swing amplitude value and the lifting parameter swing frequency value of the upper prefabricated angle steel tower. The process of monitoring the stability of the upper prefabricated angle steel tower during lifting is as follows: periodically obtain the lifting data of the upper prefabricated angle steel tower within each set monitoring period, the lifting data include the lifting swing amplitude value and the lifting swing frequency value of the upper prefabricated angle steel tower at each sampling point; compare the lifting data with the lifting parameter data to determine whether the lifting process of the upper prefabricated angle steel tower meets the lifting stability constraint conditions, and if so, the stability is met.

[0049] Firstly, a monitoring cycle is set to periodically obtain the lifting data of the upper section of the assembled angle steel tower in each cycle, including the swing amplitude value and the swing frequency value. Then, the obtained lifting data is compared with the pre-set lifting parameter data. Finally, it is determined whether the lifting process of the upper section of the assembled angle steel tower meets the lifting stability constraint conditions. If so, it is considered that the stability is met.

[0050] During the set monitoring period, the lifting data of the upper assembled angle steel tower, including the swing amplitude value and the swing frequency value, are periodically obtained through sensors or monitoring devices to reflect the real-time situation during the lifting process. The obtained lifting data are compared with the pre-set lifting parameter data to analyze the difference between the actual lifting data and the expected value. According to the comparison results, it is judged whether the lifting process of the upper assembled angle steel tower meets the lifting stability constraint conditions. These constraints can be restrictions on the swing amplitude value and the swing frequency value to ensure the stability and safety of the lifting process.

[0051] The formula for the lifting stability constraint condition is: , where is the number of the sampling point, , is the total number of sampling points, Determine the swing amplitude value for the hoisting parameters of the upper assembled angle steel tower. For the The swing amplitude value of the upper assembled angle steel tower at each sampling point, Determine the swing frequency value for the hoisting parameters of the upper assembled angle steel tower. For the The swing frequency value of the upper assembled angle steel tower hoisting parameter at each sampling point is determined. is the set lifting stability exceeding limit threshold, is the weight factor of the swing amplitude deviation, is the weight factor of the swing frequency deviation, and .

[0052] In this implementation, the deviation of the swing amplitude and frequency is calculated by formula and compared with the set threshold value, so as to achieve a quantitative evaluation of the stability of the lifting process. In this way, it is possible to more accurately judge whether the lifting process meets the safety requirements, taking into account the deviation of the swing amplitude and frequency, and adjusting them through the weight factor, so that the influence of both amplitude and frequency can be balanced when judging stability. By adjusting the weight factor and The value can flexibly adjust the weights of amplitude and frequency in stability assessment according to actual conditions to adapt to different lifting environments and requirements.

[0053] Specifically, the process of matching the obtained hanging parameter data is as follows: compare the assembly environment parameters with the hanging matching data groups stored in the matching database to obtain the hanging matching similarity, wherein the hanging matching data group includes a safe wind speed matching value, a direction matching value and a lifting equipment vibration matching value; obtain the hanging parameter data corresponding to the hanging matching data group corresponding to the smallest hanging matching similarity.

[0054] The calculation formula for the hanging matching similarity is: ; In the formula, For the hanging matching similarity, For safe wind speed, is the safe wind speed matching value, is the vibration value of the lifting equipment, is the vibration matching value of the hoisting equipment, For wind direction, is the wind direction matching value, is the wind speed hanging weight factor, is the equipment vibration hanging weight factor, is the windward hanging weight factor, and .

[0055] In this implementation scheme, first, the assembly environment parameters are compared with the various hanging matching data groups stored in the matching database, and the hanging matching similarity is calculated. Then, based on the calculated hanging matching similarity, the hanging matching data group corresponding to the minimum matching similarity is found. Finally, the corresponding hanging parameter data is obtained from this matching data group to guide the actual hanging operation.

[0056] Compare the assembly environment parameters with the various hanging matching data groups stored in the matching database, and calculate the hanging matching similarity. The matching data group includes the safe wind speed matching value, the hoisting equipment vibration matching value and the wind direction matching value, which are used to measure the matching degree of each factor. Calculate the hanging matching similarity according to the given formula. The formula takes into account the differences between the safe wind speed, the hoisting equipment vibration value and the wind direction, as well as the distance between them and the matching value, and adjusts the influence of each factor on the similarity through the weight factor. Find the matching data group with the smallest hanging matching similarity, that is, the matching data group with the highest similarity. Obtain the corresponding hanging parameter data from this matching data group to ensure the stability and safety of the hanging operation.

[0057] According to the comparison results of the current environmental parameters and the matching values, the most matching hanging parameter data is selected to provide personalized guidance and reference for the hoisting operation, which improves the accuracy and safety of the hoisting. The matching process can provide real-time feedback based on the current environmental conditions and the status of the hoisting equipment to ensure that the hoisting operation is always carried out under safe and stable conditions.

[0058] Specifically, the hanging parameter data include the parameter position data of the upper main material and the lower main material and the parameter horizontal distance data of the upper main material seat plate and the tilting auxiliary part. The process of monitoring the stability of the docking installation of the upper prefabricated angle steel tower and the lower prefabricated angle steel tower based on the matched hanging parameter data is as follows: obtain the hanging data, the hanging data include the position data of the upper main material and the lower main material and the horizontal distance data of the upper main material seat plate and the tilting auxiliary part; compare the hanging data with the hanging parameter data to determine whether the process of docking installation of the upper prefabricated angle steel tower and the lower prefabricated angle steel tower meets the hanging stability constraint condition, if so, the stability is satisfied.

[0059] The process of obtaining the hanging data is as follows: calculate the distance between the median vertical line of the bottom end of the upper main material of the upper section prefabricated angle steel tower and the median vertical line of the top end of the lower main material corresponding to the lower section prefabricated angle steel tower, and record it as the position data of the upper main material and the lower main material; calculate the horizontal straight-line distance between the edge of the upper main material seat plate of the upper main material section of the upper section prefabricated angle steel tower and the inclined auxiliary part corresponding to the lower section prefabricated angle steel tower, and record it as the horizontal distance data between the upper main material seat plate and the inclined auxiliary part.

[0060] First, obtain the hanging data, including the position data of the upper main material and the lower main material and the horizontal distance data between the upper main material base plate and the tilting auxiliary parts. Then, compare the hanging data with the hanging parameter data. Finally, judge whether the stability of the docking installation of the upper and lower prefabricated angle steel towers meets the hanging stability constraint conditions based on the comparison results.

Compare the obtained hanging data with the pre-set hanging parameter data, and analyze the difference between the actual hanging data and the expected value. According to the comparison results, determine whether the process of docking and installing the upper assembled angle steel tower and the lower assembled angle steel tower meets the hanging stability constraint conditions. The constraint conditions are restrictions on the position data and horizontal distance data to ensure stability and safety during the hoisting process.

According to the given constraint formula, the calculated distance data is substituted to calculate the deviation of the distance between the main materials and the horizontal distance between the upper main material seat plate and the tilting auxiliary part. According to the calculation results, it is judged whether each distance data meets the set constraint conditions.
