Description

Technical Field

[0001] The present invention relates to the field of building technology, and in particular to a multi-degree-of-freedom plumb adjustment device for precast wall panels, and a multi-degree-of-freedom plumb adjustment system for precast wall panels using the plumb adjustment device. Background Art

[0002] In the field of modern building construction, precast wall panels are widely used due to their advantages such as high efficiency, environmental protection, and controllable quality. However, the installation of precast wall panels requires precise verticality adjustment to ensure the safety and stability of the structure. Traditional plumb adjustment methods usually rely on manual adjustment or single adjustment devices, which are inefficient, lack precision, and are greatly affected by human factors. For example, construction workers often need to manually adjust the length and angle of the diagonal bracing steel pipes, and at the same time use tools such as a level or a plumb bob to measure the verticality. The construction workers need to repeatedly use the level or the plumb bob to measure the verticality and manually adjust the diagonal bracing rod at the same time. The process is cumbersome and error-prone. In addition, some plumb adjustment devices can only adjust the length or angle of the diagonal bracing steel pipe. For example, adjust the length first and then the angle. It may affect the previous length adjustment due to the angle change, and multiple repeated operations are required. Multi-degree-of-freedom adjustment cannot be performed simultaneously, which limits the flexibility and precision of plumb adjustment. There are also some plumb adjustment systems that use split monitoring and adjustment devices. The installation process is cumbersome and requires high installation precision, which further increases the construction difficulty and cost. The fixed support structure cannot be adjusted in real time according to the actual installation state of the precast wall panel, and it is difficult to adapt to complex construction environments and the installation requirements of different precast wall panels. Summary of the Invention

[0003] The purpose of the present invention is to provide a multi-degree-of-freedom plumb adjustment device for precast wall panels, aiming to improve the flexibility and precision of plumb adjustment for precast wall panels.

[0004] To achieve the above object, the technical solution adopted by the present invention is: to provide a multi-degree-of-freedom plumb adjustment device for precast wall panels, including: an upper support seat and a lower support seat respectively connected to the precast wall panel and the bottom surface, and a diagonal bracing rod with both ends respectively connected to the upper support seat and the lower support seat. An adjustment assembly is provided between the diagonal bracing rod and the lower support seat; The adjustment assembly includes a length adjustment assembly for adjusting the length of the diagonal bracing rod and an angle adjustment assembly for adjusting the angle between the diagonal bracing rod and the lower support seat. The length adjustment assembly is arranged at the bottom of the diagonal bracing rod, and the angle adjustment assembly is arranged on the lower support seat. The length adjustment assembly and the angle adjustment assembly are coaxially arranged with the diagonal bracing rod, and a power conversion assembly is arranged between the length adjustment assembly and the angle adjustment assembly; The power conversion component has a first working state for driving the length adjustment component to move and a second working state for driving the angle adjustment component to move through an electromagnetic clutch. In the first working state, the electromagnetic clutch is energized, and the angle adjustment component remains fixed in position. In the second working state, the electromagnetic clutch is de-energized, and the length adjustment component remains stationary.

[0005] Further, the power conversion component includes a housing, a planetary gear set disposed within the housing, and a drive motor.

[0008] Further, a slide plate for supporting the shaft rod is provided on the lower support seat, and a chute for the slide plate to slide along with the shaft rod is provided on the lower support seat in a direction perpendicular to the slide plate.

[0009] Further, a locking component for the slide plate to slide relative to the chute is also provided on the lower support seat.

[0010] Further, the locking component includes a toothed plate disposed at the top of the inner wall of the sliding groove, a magnetic strip disposed at the end of the toothed plate, and a sliding rod disposed in the middle of the toothed plate. The sliding rod is slidably disposed on the lower support base, and a spring is sleeved on the sliding rod. A rack corresponding to the toothed plate is provided on the sliding plate. A magnetic attraction portion is provided on the inner wall of the sliding groove corresponding to the magnetic strip. In the power-off state, the magnetic attraction portion releases the attraction to the magnetic strip, and the sliding rod drives the toothed plate to slide downwards, so that some of the teeth in the toothed plate are inserted into the rack.

[0011] The beneficial effects of a multi-degree-of-freedom verticality adjustment device for precast wall panels provided by the present invention are as follows: Compared with the prior art, the multi-degree-of-freedom verticality adjustment device for precast wall panels of the present invention integrates a length adjustment component and an angle adjustment component, and uses a power conversion component to switch between these two adjustment modes, realizing multi-degree-of-freedom adjustment of the position and posture of the precast wall panel. Construction workers can flexibly adjust the position of the precast wall panel according to actual needs to ensure that its verticality meets the requirements.

[0012] At the same time, since the length adjustment component and the angle adjustment component are both coaxially arranged with the inclined strut, the accuracy and stability during the adjustment process are guaranteed. This coaxial design reduces the adjustment deviation caused by mechanical errors and improves the overall accuracy of the system.

[0013] The entire verticality adjustment device has a compact structure, and the cooperation between components is tight, which not only ensures the stability and reliability of the system, but also facilitates on-site operation.

[0017] The beneficial effects of a multi-degree-of-freedom verticality measurement system for precast wall panels provided by the present invention are as follows: Compared with the prior art, the multi-degree-of-freedom verticality measurement system for precast wall panels of the present invention integrates an angle sensor, a displacement sensor and a verticality sensor, and the system can real-time monitor the position and attitude of the precast wall panel, ensuring the comprehensiveness and accuracy of the data. Accurately calculate the initial verticality deviation and set the target angle and length, avoiding the accumulation of errors and achieving high-precision adjustment.

[0018] The automation and intelligent design greatly reduce the need for manual intervention.

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved in this embodiment clearer, the following further elaborates on this embodiment in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this embodiment and are not used to limit this embodiment.

[0023] Please refer to Figures 1 to 6 for a description of a multi-degree-of-freedom verticality adjustment device for precast wall panels provided in this embodiment. A multi-degree-of-freedom verticality adjustment device for precast wall panels in this embodiment includes an upper support base 1 and a lower support base 2 respectively connected to the precast wall panel and the bottom surface, and a diagonal strut 3 with both ends respectively connected to the upper support base 1 and the lower support base 2. An adjustment component is provided between the diagonal strut 3 and the lower support base 2.

[0024] Among them, the adjustment component includes a length adjustment component for adjusting the length of the diagonal strut 3 and an angle adjustment component 5 for adjusting the angle between the diagonal strut 3 and the lower support base 2. The length adjustment component is arranged at the bottom of the diagonal strut 3, and the angle adjustment component 5 is arranged on the lower support base 2. The length adjustment component and the angle adjustment component 5 are both coaxially arranged with the diagonal strut 3, and a power conversion component 6 is arranged between the length adjustment component and the angle adjustment component 5.

[0025] Among them, the diagonal bracing rod is made of high-strength seamless steel pipe, with a material yield strength ≥ 450 MPa and a tensile strength ≥ 550 MPa, ensuring that it can bear the weight of the precast wall panel and the dynamic load during the construction process.

[0026] The wall thickness of the diagonal bracing rod is increased to 5 mm, and the thread design accuracy of the internal hollow structure reaches 6H / 6g (tolerance grade), ensuring the strength and accuracy of the thread fit.

[0027] The upper support base 1 and the lower support base 2 are made of high-strength cast steel material, with a yield strength ≥ 350 MPa and a tensile strength ≥ 450 MPa to meet the requirement of bearing the weight of the precast wall panel. In addition, the power conversion component 6 has a first working state for driving the length adjustment component to move and a second working state for driving the angle adjustment component 5 to move. In the first working state, the angle adjustment component 5 remains fixed in position, and in the second working state, the length adjustment component remains stationary.

[0028] In the precast wall panel multi-degree-of-freedom plumbness adjustment device of this embodiment, by integrating the length adjustment component and the angle adjustment component 5 and using the power conversion component 6 to switch between these two adjustment modes, the multi-degree-of-freedom adjustment of the position and attitude of the precast wall panel is achieved. Construction workers can flexibly adjust the position of the precast wall panel according to actual needs to ensure that its verticality meets the requirements.

[0029] Based on the overall introduction of the above structure, an exemplary device of a precast wall panel multi-degree-of-freedom plumbness adjustment device in this embodiment Figure 1 and Figure 2 as shown. The diagonal bracing rod 3 is a hollow sleeve rod, and internal threads are provided on the inner wall of the diagonal bracing rod 3. The above-mentioned length adjustment device includes a connecting rod 4 inserted into the bottom end of the diagonal bracing rod 3. External threads are provided on the outer peripheral side of the connecting rod 4. Thus, by rotating the connecting rod 4, through the thread fit between the connecting rod 4 and the diagonal bracing rod 3, while the connecting rod 4 rotates itself, the connecting rod 4 can move relative to the diagonal bracing rod 3, so as to enter the diagonal bracing rod 3 or slide out of the diagonal bracing rod 3, thereby achieving the effect of adjusting the overall length of the diagonal bracing rod 3 for supporting the precast wall panel. For precast wall panels with different volumes or different weights, multiple groups of plumbness adjustment devices in this embodiment are designed according to actual needs.

[0030] In this embodiment, the structure of the lower support base 2 is as shown in Figure 1 and Figure 4 as shown. On one side of the bottom of the lower support base 2 in contact with the bottom surface, a bottom plate is provided, and two symmetrically arranged annular support structures are provided in the middle of the bottom plate. The angle adjustment component 5 is arranged in the middle space of the two annular support structures.

[0031] As a preferred implementation manner, as shown in Figure 3As shown, the angle adjustment assembly 5 includes a shaft rod 51 with one end axially connected to the aforementioned power conversion assembly 6, and two meshing bevel gears 52. One bevel gear 52 is arranged at the other end of the shaft rod 51, and the other bevel gear 52 is fixedly arranged on the lower support base 2. When the power conversion assembly 6 drives the shaft rod 51 to rotate, the meshing transmission of the two bevel gears 52 converts the rotation of the shaft rod 51 into the rotation of the bevel gear 52 relative to the annular support structure, thereby realizing the change of the overall structure angle of the diagonal strut 3 to adapt to the adjustment requirements of different angles, and further enhancing the range and flexibility of angle adjustment.

[0032] Among them, in this embodiment, referring to Figure 4 as shown in, the lower support base 2 is provided with a sliding plate 21 for supporting the shaft rod 51, and along the direction perpendicular to the sliding plate 21, the lower support base 2 is provided with a sliding groove 22 for the sliding plate 21 to slide along with the shaft rod 51. Under the action of providing support for the shaft rod 51, the sliding plate 21 can also slide relative to the sliding groove 22 along the sliding groove 22 to improve the smoothness of the angle change of the entire diagonal strut 3 structure.

[0033] In addition, as a preference, in this embodiment, a locking assembly 23 for the sliding plate 21 to slide relative to the sliding groove 22 is further provided on the lower support base 2, and the locking assembly 23 ensures the stability after angle adjustment.

[0034] As a preferred implementation manner, still as Figure 4 shown, the locking assembly 23 includes a toothed plate 231 arranged at the top of the inner wall of the sliding groove 22, a magnetic strip arranged at the end of the toothed plate 231, and a sliding rod arranged in the middle of the toothed plate 231. The sliding rod is slidably arranged on the lower support base 2. A rack 211 corresponding to the toothed plate 231 is arranged on the sliding plate 21, and a magnetic attraction part corresponding to the magnetic strip is arranged on the inner wall of the sliding groove 22. In the power-off state, the magnetic attraction part releases the attraction to the magnetic strip, and the sliding rod drives the toothed plate 231 to slide downwards, so that part of the teeth in the toothed plate 231 are inserted into the rack 211 to realize the locking of the sliding plate 21, thereby achieving the effect of restricting the angle change of the diagonal strut 3. Among them, a spring 232 is sleeved on the sliding rod. When the toothed plate 231 slides downwards, the spring 232 can push the toothed plate 231 to slide downwards, so as to ensure that it can slide down quickly and lock when powered off.

[0035] In this embodiment, a preferred implementation manner of the above-mentioned power conversion assembly 6, referring to Figure 2As shown in the figure, the power conversion assembly 6 includes a housing 61, a planetary gear set 62 and a drive motor 63 disposed within the housing 61. The planetary gear set 62 includes a sun gear 621, a plurality of planetary gears 622, a planet carrier 623 connecting the plurality of planetary gears 622, and a ring gear 624. The plurality of planetary gears 622 are distributed around the sun gear 621 and meshed with the sun gear 621. The ring gear 624 is rotatably disposed within the housing 61 and distributed outside the plurality of planetary gears 622. The ring gear 624 is meshed with the plurality of planetary gears 622. The planet carrier 623 is disposed on one side of the sun gear 621 close to the lower support base 2. The planet carrier 623 and the sun gear 621 are on the same axis and are simultaneously connected to the gear shafts of the plurality of planetary gears 622. The drive motor 63 is disposed between the planet carrier 623 and the sun gear 621, and the output shaft of the drive motor 63 is connected to the sun gear 621. The drive motor 63 is rotatably disposed within the main shaft of the planet carrier 623 through a coupling shaft 64.

[0036] Among them, the planetary gear set 62 and the housing 61 are made of high-strength aluminum alloy, which not only ensures the strength but also reduces the weight of the device. And the planetary gear set 62 adopts a high-precision gear processing technology, and the gear precision level reaches DIN 6 level, ensuring high precision and low wear during the transmission process. When the length of the diagonal strut 3 needs to be adjusted, keep the planet carrier 623 stationary. At this time, the power of the drive motor 63 is transmitted to the sun gear 621. At this time, due to the limitation of the planet carrier 623, the planetary gears 622 keep rotating on their own axes and transmit the power of the sun gear 621 to the ring gear 624. The ring gear 624 is connected to the connecting rod 4 in the angle adjustment assembly 5, thereby driving the connecting rod 4 to rotate, and thus realizing the change of the overall length of the diagonal strut 3.

[0037] When the angle of the diagonal strut 3 needs to be adjusted, release the restriction on the planet carrier 623. At this time, the power of the drive motor 63 is transmitted to the sun gear 621. At this time, since the planet carrier 623 is in a free state, the planetary gears 622 can rotate around the sun gear 621 while rotating on their own axes, and the planet carrier 623 rotates accordingly. At this time, the main shaft of the planet carrier 623 is connected to the shaft rod 51 to drive the shaft rod 51 to rotate. While the bevel gear 52 at the end of the shaft rod 51 rotates relative to the other bevel gear 52, it can also rotate around the other bevel gear 52, thereby realizing the change of the overall angle of the diagonal strut 3.

[0038] Among them, relative rotation can occur between the ring gear 624 and the housing 61. However, it should be noted that a relatively large frictional force is required for the rotation between the two, so that when the planet carrier 623 can rotate relative to the housing 61, the ring gear 624 can remain stationary relative to the housing 61.

[0039] In addition, the structure for locking the carrier 623 can be based on the locking pin or electromagnetic brake structure of the transmission in the prior art. For example, an electromagnetic clutch is installed between the carrier 623 of the planetary gear set 62 and the housing 61 to control the movement state of the carrier 623. The electromagnetic clutch consists of an electromagnetic coil 651, an armature 652, and a friction plate 653. When the electromagnetic clutch is energized, the electromagnetic coil generates a magnetic field to attract the armature, causing the friction plate to engage with the carrier 623, thereby locking the carrier 623 and preventing it from rotating. When the electromagnetic clutch is de-energized, the magnetic field disappears, the armature separates from the friction plate, and the carrier 623 is in a free state and can rotate with the planetary gear 622.

[0040] A multi-degree-of-freedom plumb adjustment device for precast wall panels in this embodiment. The core of the device lies in its length adjustment component and angle adjustment component 5, both of which are coaxially arranged with the diagonal brace 3, ensuring accuracy and stability during the adjustment process. The length adjustment component is located at the bottom of the diagonal brace 3 and can adjust the length of the diagonal brace 3, thereby changing the height or inclination angle of the precast wall panel. The angle adjustment component 5 is arranged on the lower support base 2 and is responsible for adjusting the angle of the diagonal brace 3 relative to the lower support base 2. This design enables the attitude of the precast wall panel to be adjusted independently without changing the length of the diagonal brace 3, further improving the flexibility and precision of the adjustment.

[0041] The power conversion component 6 is a key part of the multi-degree-of-freedom adjustment. It can switch between two working states: driving the length adjustment component to move in the first working state and driving the angle adjustment component 5 to move in the second working state. This design enables a single drive source to complete multiple adjustment tasks, simplifies the device structure, and improves efficiency. In addition, through the combination of different mechanical components such as the connecting rod 4, the planetary gear set 62, and the bevel gear 52, multiple ways of angle adjustment are provided, enhancing the flexibility and adaptability of the system.

[0042] This embodiment also provides a multi-degree-of-freedom plumb measurement system for precast wall panels. The system uses the above-mentioned multi-degree-of-freedom plumb adjustment device for precast wall panels and also includes a sensor network array, a controller, a data acquisition module, a data processing module, a communication module, and a user interface.

[0043] Among them, the sensor network array includes an angle sensor, a displacement sensor, and a verticality sensor; the angle sensor is installed on the shaft rod 51, and preferably, a high-precision threaded connection or snap is used to fix the angle sensor at the end of the shaft rod 51 for real-time monitoring of the angle change of the diagonal strut 3, and at the same time, the coaxiality of the angle sensor and the shaft rod 51 is ensured to reduce the measurement error. The displacement sensor is installed on the diagonal strut 3, and preferably, the displacement sensor should be installed in the internal hollow part of the diagonal strut 3, near the threaded fitting area of the connecting rod 4, for real-time monitoring of the length change of the diagonal strut 3. The verticality sensor is installed at the center position of the precast wall panel. Specifically, a high-precision fixing device (such as a special bracket or adhesive) is used to install the verticality sensor at the center position of the precast wall panel for real-time monitoring of the verticality of the precast wall panel to ensure that the sensor is perpendicular to the surface of the precast wall panel to reduce the installation error.

[0044] Among them, the angle sensor uses a high-precision photoelectric encoder, the displacement sensor uses a high-precision linear grating scale, and the verticality sensor uses a high-precision electronic level.

[0045] In addition, the controller communicates wirelessly with the sensor network array. The controller includes a control center and an alarm unit. The control center receives sensor data, calculates adjustment instructions, and controls the adjustment device. The alarm unit receives abnormal signals from the control center and gives an alarm prompt.

[0046] The data acquisition module is connected to the sensor network array by signals and real-time feedbacks the data of the sensor network array; the data processing module is between the data acquisition module and the communication module and is responsible for real-time processing of the acquired data to convert it into data in a format suitable for the control center in the controller; the communication module transmits the processed data to the controller; the user interface is connected to the controller to display real-time data and operation instructions.

[0047] The specific verticality measurement method of the verticality measurement system is as follows: S1. Real-time collect the verticality data of the precast wall panel and record the verticality deviation; Use the verticality sensor to measure the initial verticality deviation of the precast wall panel ; Start the verticality sensor to ensure that the sensor is calibrated and in normal working condition.

[0048] Install the verticality sensor at the center position of the precast wall panel to ensure that it is perpendicular to the wall panel surface.

[0049] Collect the initial verticality data of the precast wall panel through the sensor and record the verticality deviation value .

[0050] S2. Obtain the target angle of the diagonal strut according to the verticality deviation of the precast wall panel; According to the initial verticality deviation of the precast wall panel , calculate the target angle α of the diagonal bracing steel pipe; Assume the height of the precast wall panel is H, and the initial length of the diagonal bracing steel pipe is , and the initial verticality deviation is .

[0051] The goal is to make the precast wall panel reach a vertical state ( = 0°). According to the trigonometric function relationship, calculate the target angle α of the diagonal bracing steel pipe: α = arctan(H / ( )) If the verticality deviation of the precast wall panel is negative (tilting to the left), the target angle α is positive; conversely, if the verticality deviation is positive (tilting to the right), the target angle α is negative. Among them, the target angle α is controlled within a reasonable range (such as ±15°).

[0052] Input the target angle α through the user interface, and the controller controls the angle adjustment device to adjust the angle according to the input instruction; Input the calculated target angle α on the user interface (such as a touch screen or an operation panel). The controller receives the input instruction and calculates the adjustment instruction according to the target angle α. The controller drives the angle adjustment component through the power conversion component to adjust the angle of the diagonal bracing steel pipe.

[0053] Real-time monitor the reading of the angle sensor to ensure that the angle of the diagonal bracing steel pipe reaches the target value α; The angle sensor real-time monitors the angle change of the diagonal bracing steel pipe and transmits the data to the controller. The controller receives the reading of the angle sensor and compares it with the target angle α. If the deviation between the actual angle and the target angle exceeds the allowable range (such as ±0.1°), the controller continues to adjust the angle adjustment component until the angle reaches the target value.

[0054] Among them, it should be noted that if the reading of the angle sensor still does not reach the target value α (error range ±0.1°) in 3 consecutive measurements, the controller will automatically trigger the fault diagnosis program. At this time, the system will check the following possible problems: Sensor failure: Check whether the angle sensor is working properly. If the sensor fails, the system will prompt to replace or recalibrate the sensor. Specifically, if the sensor data exceeds the reasonable range or shows a jump, the system will automatically mark the data as invalid and start the backup sensor for data verification. If the data of the backup sensor is normal, the system will switch to the backup sensor to continue working and prompt the maintenance personnel to check the faulty sensor.

[0055] Power conversion component failure: Check whether the power conversion component is operating normally. If any abnormality is found, the system will suspend the adjustment and prompt the maintenance personnel to check the power conversion component.

[0056] Mechanical jamming: If both the sensor and the power conversion component are normal, the system will prompt to check whether the diagonal strut and the angle adjustment component are unable to adjust the angle in place due to mechanical jamming. The maintenance personnel can manually loosen the relevant components and then restart the adjustment program. Specifically, if the length adjustment component or the angle adjustment component experiences jamming or out-of-step during operation, the system will suspend the current operation, record the fault information, and prompt the maintenance personnel to check. After troubleshooting, the system can continue to execute the adjustment task from the last recorded state to ensure that the construction progress is not affected.

[0057] If all the above inspections are normal but the angle still cannot reach the target value, the system will record the abnormal data and prompt to further check the installation status of the precast wall panel or other potential problems.

[0058] The locking component 23 locks the angle of the diagonal strut steel pipe to ensure its stability; When the angle of the diagonal strut steel pipe reaches the target value α, the controller issues a locking instruction. The locking component 23 acts to fix the angle of the diagonal strut steel pipe. The operator can manually check the locking status to ensure reliable locking.

[0059] S3. Obtain the target length of the diagonal strut according to the target angle of the diagonal strut; According to the initial verticality deviation of the precast wall panel and the target angle α of the diagonal strut steel pipe, calculate the target length L of the diagonal strut steel pipe; According to the trigonometric function relationship, calculate the target length L of the diagonal strut steel pipe: L = H / sin(α) Among them, the target length L should be controlled within a reasonable range (such as not exceeding the maximum adjustment length of the diagonal strut steel pipe).

[0060] Input the target length L through the user interface, and the controller controls the length adjustment device to adjust the length according to the input instruction; Input the calculated target length L in the user interface. The controller receives the input instruction and calculates the adjustment instruction according to the target length L. The controller drives the length adjustment component (such as a threaded connecting rod) through the power conversion component to adjust the length of the diagonal strut steel pipe.

[0061] Real-time monitor the reading of the displacement sensor to ensure that the length of the diagonal strut steel pipe reaches the target value L; The displacement sensor monitors the length change of the diagonal bracing steel pipe in real time and transmits the data to the controller. The controller receives the readings of the displacement sensor and compares them with the target length L. If the deviation between the actual length and the target length exceeds the allowable range (such as ±1 mm), the controller continues to adjust the length adjustment component until the length reaches the target value.

[0062] S4. Redetect the perpendicularity data of the precast wall panel; The perpendicularity sensor re-measures the perpendicularity deviation θ of the precast wall panel; S5. Evaluate the verticality adjustment effect according to the set deviation threshold.

[0063] The controller receives the reading θ of the perpendicularity sensor and compares it with the initial perpendicularity deviation for comparison.

[0064] The controller calculates the difference between the current deviation and the initial deviation: Δθ = θ - If Δθ decreases significantly, it indicates that the verticality adjustment operation is effective, and continue to adjust according to the current strategy.

[0065] If Δθ does not change significantly or increases, it indicates that there may be a problem with the verticality adjustment operation. This abnormal electrical signal is transmitted to the alarm unit to send an alarm message, and return to step S2 to recalculate the target angle and length.

[0066] At the same time, the controller repeatedly executes S2 to S6 to further adjust the angle and length of the diagonal bracing steel pipe until the difference in the initial perpendicularity deviation Δθ remains unchanged, and determines that the perpendicularity of the precast wall panel reaches the expected standard.

[0067] Among them, the maximum number of times the controller repeatedly executes S2 to S6 is 5 times. If the target is not reached within the maximum number of times, it indicates that there may be a problem with the verticality adjustment operation. This abnormal electrical signal is transmitted to the alarm unit to send an alarm message, prompting the operator to perform a manual inspection.

[0068] For a multi-degree-of-freedom verticality measurement system of a precast wall panel in this embodiment, the complete process from initial measurement to final verticality adjustment effect evaluation includes calculating the target angle α and the target length L, adjusting through the controller instruction execution mechanism, and using sensors for real-time monitoring to ensure the accuracy of the adjustment. This process ensures the precise control and verification of the perpendicularity of the precast wall panel, greatly improving the construction quality and reliability.

[0069] The above are only the preferred embodiments of this embodiment, and are not intended to limit this embodiment. Any modifications, equivalent replacements, and improvements made within the spirit and principles of this embodiment shall be included within the protection scope of this embodiment.
