[0009] Furthermore, the step of marking the center point of the foundation before installing the lower anchor plate includes: The position of the base center point is measured by RTK, and the base center point is marked by a marker.

[0010] Furthermore, the step of determining the first angle includes: Measure the length of the level detection device; Determine the first distance and the second distance based on the length of the horizontal detection device and the design drawings of the wind turbine generator set foundation anchor cage; The arc tangent of the first distance and the second distance is calculated to obtain a first angle.

[0011] Furthermore, before the step of marking the center point of the foundation before the lower anchor plate is installed, the method further comprises: Check the parameters of the embedded parts of the lower anchor plate; wherein the parameters include: the number, size and position of the embedded parts.

[0012] Furthermore, between the step of installing a corresponding number of centering and leveling devices at the preset installation points and adjusting the laser emission angle of the centering and leveling devices to a first angle and the step of adjusting the current position of the lower anchor plate through the level detection modules of the centering and leveling devices to adjust the overall levelness of the lower anchor plate, the method further includes: The lower anchor plate is moved to above the supporting bolts of the embedded parts by means of a lifting device; Adjust the position of the lower anchor plate by lifting equipment so that the support bolts pass through the screw holes of the lower anchor plate; Nuts are set on the upper and lower parts of the lower anchor plate to preliminarily fix the lower anchor plate on the embedded parts.

[0015] Beneficial effects: The present invention calculates the first angle and uses multiple centering and leveling devices to accurately adjust the concentricity and horizontality of the lower anchor plate, thereby significantly improving the accuracy and construction efficiency of the installation of the lower anchor plate. Specifically, the calculation of the first angle calibrates the concentricity of the lower anchor plate by determining the distance relationship between the top surface of the lower anchor plate and the center point of the foundation. When multiple centering and leveling devices emit lasers according to the first angle, if all laser beams converge at the center point of the foundation, it indicates that the concentricity of the lower anchor plate meets the requirements; conversely, if there is a deviation, the position of the lower anchor plate is adjusted so that all laser beams finally converge at the center point of the foundation to ensure that the lower anchor plate is aligned with the center of the foundation. Accordingly, the horizontality of the lower anchor plate is adjusted by the horizontal detection modules carried by the multiple centering and leveling devices. Such a method greatly reduces the reliance on manual operation, improves the accuracy of installation, and avoids errors and inaccurate manual adjustments that may occur in traditional technologies. Through this precise automated adjustment process, not only the efficiency of the installation process is improved, but also the complexity of adjustment and the construction period are reduced. In addition, during the entire installation process, the use of lasers and the automatic adjustment mechanism effectively ensured the concentricity and horizontality of the lower anchor plate during installation, avoiding errors that may occur during manual measurement and adjustment, and ensuring the stability and safety of the wind turbine foundation.

DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0018] During the construction of a wind turbine, the installation of the foundation anchor cage is a crucial link. The stability of the foundation anchor cage directly affects the installation quality of the entire wind turbine and the safety of subsequent operation. The installation process usually involves multiple complex links, including the installation of the lower anchor plate, the assembly of anchor bolts, the installation of the upper anchor plate, and the final adjustment and fixation. Specifically, when installing the lower anchor plate, a crane is required to accurately position the lower anchor plate, and the horizontality and concentricity of the support bolts are manually adjusted; the anchor bolt assembly stage requires the precise placement of the positioning anchor bolts, and manual operation is used to ensure the verticality of the anchor bolts and the integrity of the threads; and the installation of the upper anchor plate requires the use of a crane and manual cooperation to dock the anchor bolts with the lower anchor plate to ensure the alignment accuracy of the two anchor plates.

[0019] However, existing installation methods rely on a lot of manual operations and multiple adjustments. First, during the installation process, the operator needs to repeatedly adjust the position of the support bolts to ensure that the lower anchor plate reaches the precise level, and to ensure concentricity through visual inspection and manual measurement. Although mechanical equipment such as cranes are used to assist in the operation, the accuracy of each step of the operation is highly dependent on manual labor and is easily affected by the technical level of on-site personnel, environmental factors, etc. Since each step in the construction requires manual measurement and fine-tuning, the installation process is extremely lengthy. Manual operation not only increases construction time, but may also introduce errors, reducing the overall efficiency of construction.

[0020] Further analysis shows that the construction methods in the prior art have high repetitiveness in many links, and the precision adjustment required during the installation process is almost entirely dependent on manual control, which leads to low construction efficiency and prone to errors. In addition, the installation and subsequent adjustment of anchor bolts, especially in large-scale wind power generation projects, often require multiple inspections and corrections to ensure that the installation of each component meets the design requirements.

[0021] Therefore, the biggest technical problem of the prior art is that during the installation of the anchor cage of the wind turbine foundation, the installation and construction efficiency is low. It is precisely to address the problems of low efficiency, poor precision and long construction period exposed in the above-mentioned prior art that this embodiment proposes a brand-new method. By using a laser centering and leveling device, on the basis of automatic adjustment and precise positioning, the installation accuracy of the lower anchor plate and the upper anchor plate is improved, and the intervention of manual operation is reduced, thereby greatly improving the installation efficiency and construction accuracy.

[0022] like Figure 1 and Figure 2 As shown, a method for installing a lower anchor plate is provided, wherein the lower anchor plate is a lower anchor plate in a foundation anchor cage of a wind turbine generator set, and the method comprises: Step S12: Before installing the lower anchor plate, mark the center point of the foundation.

[0023] In this embodiment, before installing the lower anchor plate, the number, size and position of the embedded parts of the lower anchor plate can be checked according to the requirements of the foundation drawing. Then the center point of the foundation is measured using RTK and marked with black or other colors. Other markers or markings can also be used to mark the center point of the foundation.

[0024] Step S14: determine the first angle; wherein the first angle is the arctangent value of the ratio of the first distance to the second distance; wherein the first distance is the distance from the top surface of the lower anchor plate to the foundation cushion plus the preset distance when the lower anchor plate is in the installation position; the second distance is the horizontal distance from the preset installation point on the top surface of the lower anchor plate to the center point of the foundation when the lower anchor plate is in the installation position; wherein a plurality of preset installation points are arranged on the top surface of the lower anchor plate; wherein the preset installation points are used to install a centering and leveling device, and the preset distance is the vertical length of the centering and leveling device when it is in use.

[0025] In this embodiment, the distance from the top surface of the lower anchor plate to the foundation cushion layer can be determined according to the design drawings of the foundation anchor cage of the wind turbine generator set. It is understandable that the design drawings often clearly mark the distance.

[0026] In this embodiment, the preset distance may be the length of the centering and leveling device in the vertical direction when it is in use. Therefore, the length of the centering and leveling device in the vertical direction may be directly measured. In some embodiments, considering the calculation accuracy, the preset distance may also be the distance from the laser emitter of the centering and leveling device to the bottom surface of the centering and leveling device.

[0027] In this embodiment, the lower anchor plate is in the installation position, which may be the position of the lower anchor plate indicated in the design drawing, that is, the ideal installation position of the lower anchor plate (it is understandable that the design drawings often show the ideal installation position under the design conditions. In the actual installation and construction, the final installation position of the lower anchor plate often has an error with the position in the design drawing. It is also understandable that the corresponding specifications also allow for the existence of errors).

[0028] In this embodiment, a plurality of preset installation points are arranged on the top surface of the lower anchor plate, and the preset installation point can be a visual marking point for prompting the installation construction personnel to install the centering and leveling device at the position. For example, a colored pen can be used for marking. The preset installation point can also be a physical raised mark. For example, small holes can be drilled on the top surface of the lower anchor plate, and these small holes serve as position indications of the preset installation points. Through the holes, the construction personnel can accurately position the support part of the centering and leveling device.

[0029] The preset installation point can also be a mechanical mounting seat. On the top of the lower anchor plate, pre-installed fixing seats can be designed, and the positions of these fixing seats are the preset installation points. By fixing the centering and leveling devices on these seats, their precise position and angle are guaranteed. This type of design can improve the stability and accuracy of the installation.

[0030] Considering that the laser emitted by the centering and leveling device can irradiate the center point of the foundation, the preset installation point can be set at the inner edge of the top of the lower anchor plate (it can be understood that the lower anchor plate and the upper anchor plate of the wind turbine foundation anchor cage are often set in the form of a hollow ring). Therefore, by setting the preset installation point at the inner edge of the top of the lower anchor plate, the laser is not easily blocked and can directly irradiate the surface of the foundation cushion layer.

[0031] Specifically, a preset installation point can be set at a certain distance at the inner edge of the top of the lower anchor plate. For example, 10, 20, 30, etc. can be set.

[0032] In this embodiment, the second distance can also be determined according to the design drawings of the anchor bolt cage of the wind turbine generator set. It is understandable that the design drawings often clearly mark the distance.

[0033] Step S16: Install a corresponding number of centering and leveling devices at the preset installation points, and adjust the laser emission angle of the centering and leveling devices to a first angle; wherein the centering and leveling devices are at least configured to emit lasers with an adjustable angle and are configured with a horizontal detection module.

[0034] In this embodiment, the centering and leveling device can be pasted on a preset installation point.

[0035] In this embodiment, a small hole or a threaded hole may be designed near the preset installation point, and the centering and leveling device may be firmly fixed to the lower anchor plate by bolts.

[0036] In this embodiment, the centering and leveling device can be designed to have a magnetic base, which is fixed to the preset installation point of the lower anchor plate by magnetic force. This method is suitable for situations where the position needs to be quickly and conveniently replaced or adjusted during the installation process. Magnetic fixation can be quickly installed and disassembled, reducing construction time.

[0037] In this embodiment, the centering and leveling device may include a rotating laser emitter. Specifically, the centering and leveling device may be designed as a rotating bracket so that the laser emitter can rotate around a fixed axis. By adjusting the position of the bracket, the angle of laser emission can be conveniently adjusted. The bracket can achieve precise angle adjustment by rotating a nut, a knob or an electric adjustment device.

[0038] In this embodiment, the centering and leveling device may include an electric or manual angle adjustment mechanism and a laser emitter. Specifically, the centering and leveling device may have a built-in electric drive system to control the angle of the laser emitter through a remote control or button. The electric system may be equipped with a servo motor or a stepper motor, which can accurately adjust the angle of the laser emitter within a fine-tuning range. If a manual adjustment method is adopted, an adjustment knob or a screw device may be designed, which can be rotated to adjust the angle of the laser emitter. An angle ruler may be combined so that construction personnel can read and adjust the laser angle.

[0039] In this embodiment, the centering and leveling device can be a universal joint or a ball joint. Specifically, the centering and leveling device can be designed as a structure with a universal joint, so that the laser emitter can be freely adjusted in multiple directions. The universal joint can provide a wide adjustment range, can accurately control the laser emission angle, and ensure that the desired angle can be achieved in all directions.

[0040] In this embodiment, the centering and leveling device may include a level detection module. Specifically, the level detection module may be a level bubble unit.

[0041] In this embodiment, the level detection module can be an electronic level sensor. The electronic level sensor can provide digital level detection. Through the built-in sensor, the electronic level sensor can measure the horizontal state of the device in real time and display the specific deviation value. This sensor is more accurate than the traditional bubble level and is not affected by environmental factors (such as vibration and temperature changes). It is suitable for construction occasions that require high precision.

[0042] In this embodiment, the level detection module may be a photoelectric sensor.

[0043] In this embodiment, the level detection module may be a bubble level sensor.

[0044] In a specific embodiment, the centering and leveling device can be as follows Figure 3 The middle leveling device may include: A magnetic base is provided with a horizontal liquid bubble and a bracket.

[0045] A scale is arranged on one part of the bracket, and an angle scale is arranged on the other part.

[0046] The angle ruler is also equipped with a rotatable laser transmitter fixing slot, in which a laser transmitter can be installed, and the laser transmitter fixing slot can be installed on a bracket by a fixable bolt.

[0047] The laser transmitter fixing slot is also provided with a rotation angle needle.

[0048] Step S18: After the lower anchor plate is moved to the installation position, the current position of the lower anchor plate is adjusted through the level detection modules of each centering and leveling device to adjust the overall levelness of the lower anchor plate.

[0049] In this embodiment, multiple construction workers and installers can jointly adjust the current position and posture of the lower anchor plate by observing the detection results of each level detection module (for example, the horizontal bubble unit), so that the detection results displayed by each level detection module are horizontal. When the detection results displayed by multiple level detection modules are horizontal, it means that the entire lower anchor plate in this state is also horizontal. It can be understood that this process can be a preliminary adjustment of the overall horizontality of the lower anchor plate.

[0050] In this embodiment, a high-precision adjustment method for the overall horizontality of the lower anchor plate can also be provided. Specifically, the horizontal detection module can also include a measurement calibration unit (for example, it can be a scale). When performing high-precision adjustments, a horizontal laser emitting device can be placed at the construction site, for example, at the center of the lower anchor plate (the lower anchor plate is often a hollow ring) or at other locations. The height of the horizontal laser emitting device can be adjusted so that the horizontal laser emitted by the horizontal laser emitting device can be irradiated onto the scale to display the value. After the height of the horizontal laser emitting device is adjusted, the laser irradiation values ​​on each scale can be observed. If the values ​​are all displayed consistently, it means that the lower anchor plate as a whole is now at a level that meets the corresponding accuracy. If the values ​​are not displayed consistently, the position of the lower anchor plate can be further adjusted so that the values ​​are displayed consistently.

[0051] It is understandable that the preliminary adjustment is performed by observing multiple level detection modules (such as horizontal bubble units). This process allows multiple construction workers to collaborate simultaneously and quickly adjust the position of the lower anchor plate based on the detection results at different angles. Since the feedback from each level detection module is consistent, the construction workers can ensure the adjustment of the overall level of the lower anchor plate. Multi-point monitoring and collaborative adjustment in the preliminary adjustment stage can adjust the lower anchor plate to a near-ideal horizontal position in a relatively short period of time, saving a lot of time and labor costs.

[0052] High-precision adjustment further improves the accuracy of the anchor plate level by introducing a scale and a horizontal laser emitting device. This method is not only based on laser irradiation comparison, but also combines actual numerical feedback to ensure consistent readings at each detection point. When the values ​​displayed on all scales are consistent, it means that the overall levelness of the anchor plate has reached the precise requirements. Through this high-precision measurement method, construction personnel can accurately adjust the anchor plate to ensure that the accuracy standards required on the design drawings are met.

[0053] In summary, preliminary adjustment can quickly achieve basic installation accuracy, saving time and manpower, while high-precision adjustment provides more precise horizontal control to ensure perfect docking between the lower anchor plate and the foundation. The combination of the two can significantly improve the overall construction efficiency and installation quality, making the installation process of the wind turbine foundation more efficient and accurate, and greatly reducing manual errors and adjustment cycles.

[0054] Step S110: adjusting the current position of the lower anchor plate by means of the lasers emitted by the centering and leveling devices, so that the lasers emitted by the centering and leveling devices converge on the center point of the foundation to adjust the concentricity of the lower anchor plate.

[0055] This embodiment calculates the first angle and uses multiple centering and leveling devices to accurately adjust the concentricity and horizontality of the lower anchor plate, thereby significantly improving the accuracy and construction efficiency of the installation of the lower anchor plate. Specifically, the calculation of the first angle calibrates the concentricity of the lower anchor plate by determining the distance relationship between the top surface of the lower anchor plate and the center point of the foundation. When multiple centering and leveling devices emit lasers at the first angle, if all laser beams converge at the center point of the foundation, it indicates that the concentricity of the lower anchor plate meets the requirements; conversely, if there is a deviation, the position of the lower anchor plate is adjusted so that all laser beams finally converge at the center point of the foundation to ensure that the lower anchor plate is aligned with the center of the foundation. Accordingly, the horizontality of the lower anchor plate is adjusted by the horizontal detection module carried by multiple centering and leveling devices. This method greatly reduces the reliance on manual operation, improves the accuracy of installation, and avoids errors and inaccurate manual adjustments that may occur in traditional technologies. Through this precise automated adjustment process, not only the efficiency of the installation process is improved, but also the complexity of adjustment and the construction period are reduced. In addition, during the entire installation process, the use of lasers and the automatic adjustment mechanism effectively ensured the concentricity and horizontality of the lower anchor plate during installation, avoiding errors that may occur during manual measurement and adjustment, and ensuring the stability and safety of the wind turbine foundation.

[0056] It is understandable that the method of installing multiple centering and leveling devices can simultaneously monitor and adjust in real time through multiple devices through laser centering technology, solving the problem of one-by-one operation and measurement in traditional methods. The laser emitted by each centering and leveling device and the level detection module carried can be compared and calibrated at multiple installation points of the lower anchor plate at the same time, so as to synchronously adjust the concentricity and horizontality of the lower anchor plate. This automated synchronous adjustment method significantly improves the construction efficiency, because each device can work independently and can handle multiple adjustment tasks at the same time in a short time. In traditional construction methods, total stations and levels are used to measure the horizontality and concentricity of the lower anchor plate. The construction efficiency of this method is low, mainly because total stations and levels usually need to measure and calibrate each measuring point one by one, and each measurement requires the position of the instrument to be readjusted. This not only increases the complexity of the operation, but also requires constant switching of the measurement target, resulting in a waste of time in construction. Although total stations and levels can provide accurate measurement data, manual analysis and adjustment of the measurement results are still required, especially when the instrument position is calibrated based on manual judgment, errors are easily generated. Manual operation requires a high level of skill, and repeated measurements and confirmations are required after each calibration, resulting in low efficiency. When using total stations and levels, construction workers usually need to measure each position separately, and then make adjustments based on the measurement data. When making simultaneous adjustments at multiple points, traditional instruments often cannot provide feedback at multiple angles at the same time, so each adjustment needs to wait for manual confirmation and readjustment, which increases time consumption and error accumulation. Compared with traditional methods, installing multiple centering and leveling devices can quickly complete precision calibration through real-time feedback from laser emission, and can achieve simultaneous adjustment of multiple points. This makes the entire installation process more efficient, reduces manual dependence, and significantly shortens the time required for each step. Especially in large-scale wind power projects, the synchronous working mode of multiple centering and leveling devices not only improves accuracy, but also saves a lot of man-hours, ensuring high efficiency and high precision at the same time.

[0057] In some embodiments, the level detection module includes a level bubble unit, and the step of adjusting the current position of the lower anchor plate through the level detection modules of each centering and leveling device to adjust the overall levelness of the lower anchor plate includes: By observing the horizontal bubble units of each centering and leveling device and adjusting the current position of the lower anchor plate, the horizontal bubbles in the horizontal bubble units of each centering and leveling device are all directed toward the top.

[0058] This embodiment uses the horizontal bubble unit as a level detection module to intuitively determine the overall levelness of the lower anchor plate. By observing the bubble position in each centering and leveling device and adjusting the lower anchor plate, the bubble is made to tend to the top, ensuring that the lower anchor plate is in a horizontal state. This method is simple and easy to implement, reduces manual errors and operational complexity, and can efficiently perform multi-point synchronous adjustments, significantly improve construction efficiency and accuracy, and ensure the quality and stability of the foundation installation of the wind turbine generator set.

[0059] In some embodiments, the level detection module further includes a measurement calibration unit, which can feed back an indication value of the laser irradiating it; the step of adjusting the current position of the lower anchor plate through the level detection modules of each centering and leveling device to adjust the overall levelness of the lower anchor plate also includes: Turn on the preset horizontal laser emitting device to emit laser to the measuring and calibration units of each centering and leveling device in turn.

[0060] In this embodiment, a horizontal laser emitting device can be set up in advance at the construction site, for example, near the center point of the foundation, and the height of the horizontal laser emitting device can be adjusted so that the laser emitted by the horizontal laser emitting device can be irradiated on the measurement calibration unit to display the corresponding measurement value.

[0061] In this embodiment, a plurality of horizontal laser emitting devices may be pre-set, and the number of the horizontal laser emitting devices may be equal to the centering and leveling devices, and one horizontal laser emitting device corresponds to one measurement and calibration unit.

[0062] By observing the values ​​indicated by the measuring and calibration units of each centering and leveling device, the current position of the lower anchor plate is adjusted so that the values ​​indicated by each measuring and calibration unit are the same, so as to adjust the overall horizontality of the lower anchor plate.

[0063] This embodiment achieves high-precision adjustment of the overall horizontality of the lower anchor plate by combining a horizontal laser emitting device and a measuring and calibration unit. The height of the laser emitting device is set and debugged in advance at the construction site so that its laser can irradiate the measuring and calibration units of each centering and leveling device to obtain accurate measurement values. By observing the values ​​displayed by each measuring and calibration unit and making them consistent, construction personnel can accurately adjust the position of the lower anchor plate to ensure that its overall horizontality meets the design requirements. The beneficial effect of this method is that it improves the accuracy of adjustment, reduces manual errors, and through the numerical feedback of laser emission, it can quickly and effectively complete multi-point synchronous adjustment, significantly improving construction efficiency and quality.

[0064] In some embodiments, the measurement and calibration unit is a scale; the step of turning on a preset horizontal laser emitting device to sequentially emit lasers to the measurement and calibration units of each centering and leveling device includes: A horizontal laser emitting device is set up at the middle position of the lower anchor plate; In this embodiment, the lower anchor plate may be in the form of a hollow ring, and thus the horizontal laser emitting device may be installed at the middle position of the lower anchor plate, for example, near the center point of the foundation.

[0065] Turn on the horizontal laser emitting device and irradiate the laser of the horizontal laser emitting device onto the scales of each centering and leveling device in turn.

[0066] This embodiment can accurately adjust the level by setting up a horizontal laser emitting device in the middle of the lower anchor plate and irradiating its laser onto the scale of each centering and leveling device. By irradiating the laser in turn and observing the value of the scale, the construction personnel can judge the horizontal state of each measuring point in real time and make precise adjustments. The beneficial effect of this method is that the laser provides high-precision measurement feedback, avoids human errors, ensures that the level adjustment of multiple centering and leveling devices is carried out synchronously, and improves the efficiency and accuracy of the adjustment. At the same time, by using a scale for calibration, the accuracy of the lower anchor plate during installation can be ensured, significantly improving the construction quality and work efficiency.

[0067] In some embodiments, the step of marking the center point of the foundation before installing the lower anchor plate includes: The position of the base center point is measured by RTK, and the base center point is marked by a marker.

[0068] In this embodiment, the position of the foundation center point can be accurately determined by using RTK measurement technology, providing high-precision coordinate data to ensure that the installation position of the lower anchor plate is consistent with the design drawing. RTK technology has the advantage of real-time dynamic positioning, which can eliminate errors that may occur in traditional methods. By marking the foundation center point with a marker, construction workers can quickly and accurately find the installation point, reducing manual measurement and marking errors, and significantly improving the efficiency and accuracy of the installation process.

[0069] In some embodiments, the step of determining the first angle includes: Measure the length of the level detection device; Determine the first distance and the second distance based on the length of the horizontal detection device and the design drawings of the wind turbine generator set foundation anchor cage; The arc tangent of the first distance and the second distance is calculated to obtain a first angle.

[0070] In this embodiment, by measuring the length of the horizontal detection device and combining it with the design drawings, the first angle can be accurately calculated, which provides an accurate positioning basis for the subsequent installation of the lower anchor plate. The calculation of the first angle is based on the known geometric relationship and the actual measurement results, ensuring the concentricity and angle accuracy of the lower anchor plate during installation. This step avoids human errors and improves installation accuracy through the reasonable application of mathematical calculations, and provides a reliable reference angle for the laser adjustment system, ensuring the accuracy and stability of the wind turbine foundation.

[0071] In some embodiments, before the step of marking the center point of the foundation before installing the lower anchor plate, the method further comprises: Check the parameters of the embedded parts of the lower anchor plate; wherein the parameters include: the number, size and position of the embedded parts.

[0072] In this embodiment, by checking the parameters of the embedded parts, including their quantity, size and position, before installing the lower anchor plate, it can be ensured that the embedded parts meet the design requirements. This step provides an important prerequisite for the subsequent installation of anchor bolts and the centering and leveling of the lower anchor plate, avoiding installation deviations caused by the position or size of the embedded parts not meeting the standards. Pre-inspection of embedded parts can detect potential problems in advance, reduce unnecessary adjustment time during installation, improve construction efficiency and accuracy, and ensure that the lower anchor plate can be smoothly docked and meet design requirements.

[0073] In some embodiments, between the step of installing a corresponding number of centering and leveling devices at the preset installation points and adjusting the laser emission angle of the centering and leveling devices to a first angle and the step of adjusting the current position of the lower anchor plate through the level detection modules of the centering and leveling devices to adjust the overall levelness of the lower anchor plate, the method further includes: The lower anchor plate is moved to above the supporting bolts of the embedded parts by means of a lifting device; Adjust the position of the lower anchor plate by lifting equipment so that the support bolts pass through the screw holes of the lower anchor plate; Nuts are set on the upper and lower parts of the lower anchor plate to preliminarily fix the lower anchor plate on the embedded parts.

[0074] In this embodiment, the lower anchor plate is moved to the top of the embedded support bolts by hoisting equipment, and the position is adjusted so that the support bolts pass through the screw holes of the lower anchor plate. At the same time, nuts are set above and below the lower anchor plate for preliminary fixation to ensure the stability of the lower anchor plate. The beneficial effect of this process is that it provides a reliable physical basis for the subsequent adjustment of the centering and leveling device, ensuring that the position of the lower anchor plate is stable and accurate. By preliminarily fixing the lower anchor plate, it is possible to avoid the introduction of errors due to unstable position during subsequent adjustments, thereby improving the accuracy and efficiency of the overall installation. This step also creates conditions for the adjustment of the laser emission angle and precise adjustment of the horizontality of multiple centering and leveling devices, ensuring the final precise positioning of the lower anchor plate and reducing manual operations and complex fine-tuning work.
