Description

Technical Field

[0001] This utility model belongs to the field of building construction equipment technology, and specifically relates to an adsorption-type prefabricated wall panel installation dynamic calibration device. Background Technology

[0002] Prefabricated construction is the future direction of the modern construction industry, and the installation of prefabricated wall panels is a crucial step. The precision of wall panel installation directly affects the overall quality, structural safety, and aesthetics of the building.

[0003] In current precast wall panel installation, static positioning is typically achieved using traditional tools such as levels and laser levelers, followed by manual adjustments by experienced workers. This method has several drawbacks: First, the measurement process is static, making real-time dynamic monitoring impossible during panel hoisting, movement, and fine-tuning, easily leading to positional deviations due to dynamic disturbances. Second, installation accuracy and efficiency heavily rely on the workers' skill level and sense of responsibility, lacking objective and standardized criteria. Furthermore, existing mechanical clamps or temporary support devices are poorly adaptable to wall panels of different materials (such as concrete and metal composite panels) or with uneven surfaces, are cumbersome to operate, and struggle to achieve rapid and stable fixing. Therefore, the industry urgently needs equipment that can dynamically, accurately, and efficiently assist in the installation of precast wall panels. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, namely the difficulty in dynamic monitoring, low accuracy, and poor adaptability during the installation of existing wall panels, this utility model provides an adsorption-type prefabricated wall panel installation dynamic calibration device, comprising:

[0005] case;

[0006] A dynamic adsorption unit is provided on the housing and is used to detachably fix the housing to the surface of the prefabricated wall panel;

[0007] The measuring unit is installed in the internal cavity of the housing via a universal joint structure and is used to measure the tilt angle of the housing relative to the direction of gravity.

[0008] And an intelligent feedback unit, which is located on the housing and electrically connected to the measuring unit;

[0009] The dynamic adsorption unit includes at least one of a negative pressure adsorption structure and a magnetic adsorption structure;

[0010] The measurement unit includes a gravity pendulum mechanism and an angular displacement sensing component for detecting the angular displacement of the gravity pendulum mechanism.

[0011] Furthermore, the universal connection structure includes: a spherical mounting position disposed on the inner wall of the housing, and a spherical adapter sleeve, wherein the measuring unit is installed inside the spherical adapter sleeve, and the spherical adapter sleeve has a spherical profile that mates with the spherical mounting position.

[0012] Furthermore, the dynamic adsorption unit includes the negative pressure adsorption structure and the magnetic adsorption structure; wherein, the negative pressure adsorption structure is composed of a suction cup and a vacuum generator that provides negative pressure to the suction cup; the magnetic adsorption structure is composed of a magnetic strip.

[0013] Furthermore, a magnetically conductive insulating layer is provided between the housing and the suction cup; and the magnetic strips are arranged in an intermittent square shape.

[0014] Furthermore, the gravity pendulum mechanism includes a rotating shaft, a rigid pendulum rod connected to the rotating shaft, and a metal pendulum ball disposed at the end of the rigid pendulum rod; the angular displacement sensing component is linked to the rotating shaft.

[0015] Furthermore, the angular displacement sensing component is a magnetic encoder component, which includes a magnetic ring fixed to the rotating shaft and a magnetic sensor disposed on the circuit board; wherein the rotation center of the magnetic ring and the rotating shaft are not concentric.

[0016] Furthermore, the eccentricity between the magnetic ring and the rotating shaft is a specific value preset based on the radius of the magnetic ring; and the arrangement position of the magnetic sensor is offset relative to the geometric center of the magnetic ring by half of the eccentricity.

[0017] Furthermore, the rotating shaft is supported by a pair of bearings, with a spacer ring between the two bearings, and the axial position of the rotating shaft is limited by a snap ring.

[0018] Furthermore, the intelligent feedback unit includes a display screen, a buzzer, and a green indicator light; the device also includes a control module, which is electrically connected to the measurement unit, the buzzer, and the green indicator light.

[0019] Furthermore, it also includes an inertial damping block, which is elastically connected to the inner wall of the housing via a silicone buffer pad.

[0020] The beneficial effects of this utility model are:

[0021] This invention integrates a gravity pendulum mechanism and an angular displacement sensing component to monitor the dynamic attitude changes of precast wall panels during hoisting and fine-tuning in real time. Combined with the instant sound, light, and digital display prompts provided by the intelligent feedback unit, operators can make continuous and intuitive adjustments without repeated static measurements, greatly shortening calibration time and effectively avoiding installation errors caused by dynamic disturbances, thereby improving construction efficiency and final installation accuracy.

[0022] This invention's dynamic adsorption unit creatively combines negative pressure adsorption and magnetic adsorption. For non-magnetic wall panels such as concrete, vacuum suction cups can be used for fixation; for metal composite wall panels or wall panels with metal attachments, magnetic strips can be used for adsorption. This dual-mode design allows the device to be compatible with prefabricated wall panels of different materials and surfaces, solving the problem of poor adaptability of existing single clamps or adsorption methods.

[0023] This invention uses a universal connection structure (such as the fit between a spherical adapter sleeve and a spherical mounting position) to mount the measuring unit, enabling the measuring axis of the measuring unit to self-adjust and remain unaffected by the initial tilt of the housing mounting surface (i.e., the wall panel surface), always using the direction of absolute gravity as the reference. This solves the fundamental problem of measurement inaccuracy caused by uneven mounting reference surfaces in traditional single-axis sensors, ensuring measurement accuracy under complex working conditions.

[0024] This invention employs multiple anti-interference designs. First, by inertial damping blocks and silicone buffer pads, common vibrations and impacts encountered at construction sites are effectively absorbed and suppressed, ensuring the stability of the gravity pendulum mechanism. Second, a magnetically conductive isolation layer is installed between the magnetic strip and the housing, effectively shielding the magnetic adsorption structure from interference with the internal high-precision magnetic sensor. These designs ensure that the device can still output stable and reliable measurement data in noisy and vibrating complex construction environments.

[0025] The measurement unit employs a non-concentrically mounted magnetic ring and magnetic sensor, a special design that improves the detection sensitivity and resolution of angle changes. Simultaneously, the intelligent feedback unit automatically triggers a buzzer and indicator light based on preset thresholds, providing operators with a clear and unambiguous "adjustment in place" signal. This reduces reliance on operator experience and makes calibration more standardized and simplified. Attached Figure Description

[0031] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figures 1-4 As shown, see details. Figure 1 This utility model proposes an adsorption-type prefabricated wall panel installation dynamic calibration device, comprising:

[0034] The housing 1 includes a dynamic adsorption unit disposed on the housing 1 for detachably fixing the device to the surface of the precast wall panel; a measuring unit disposed inside the housing 1 for dynamically measuring the tilt angle of the precast wall panel; and an intelligent feedback unit disposed outside the housing 1, electrically connected to the measuring unit, for providing real-time calibration feedback based on the measured tilt angle.

[0035] Specifically, the device in this embodiment integrates all functional units into a compact housing 1, forming a portable, integrated calibration tool. During operation, the entire device is fixed to the prefabricated wall panel to be installed via a dynamic adsorption unit. The measurement unit then monitors the attitude changes of the wall panel in real time during hoisting, movement, and fine-tuning, transmitting the angle data to the intelligent feedback unit. The latter provides on-site construction personnel with immediate and intuitive calibration guidance through sound, light, and digital displays. This invention, by highly integrating adsorption, measurement, and feedback functions, achieves closed-loop dynamic control of the prefabricated wall panel installation process, solving the problems of separation of measurement and adjustment, low efficiency, and susceptibility to dynamic disturbances in existing technologies, making the installation and calibration process more efficient, accurate, and convenient.

[0036] See Figure 4The dynamic adsorption unit includes a negative pressure adsorption structure and a magnetic adsorption structure. To make the device applicable to precast wall panels of different materials, the dynamic adsorption unit integrates two adsorption modes. The negative pressure adsorption structure mainly includes a large-area suction cup 8 located on the outer end face of the support plate 7, and a vacuum generator 9 that provides negative pressure to the suction cup 8. The vacuum generator 9 is arranged in a cavity inside the housing 1 and is connected to the suction cup 8 via an internal pipe. When working on non-magnetic wall panels such as concrete or stone, the vacuum generator 9 is activated by pressing button 12, creating negative pressure between the suction cup 8 and the wall panel surface, generating a strong adsorption force.

[0037] The magnetic adsorption structure consists of multiple magnetic strips embedded in the edge area of ​​the suction cup 8, arranged in an intermittent U-shape to increase the contact area and adapt to uneven surfaces. When the wall panel is a steel composite panel or has metal components on its surface, it can be directly adsorbed using magnetic force. To prevent the magnetic field generated by the magnetic strips from interfering with the internal precision measuring unit, a magnetically conductive insulating layer is added between the support plate 7 and the suction cup 8 to shield the magnetic field.

[0038] This invention, through the dual structure of negative pressure adsorption and magnetic adsorption, endows the device with excellent adaptability to working conditions, enabling it to be stably adsorbed onto most types of precast wall panels, thus having a wide range of applications. At the same time, the magnetically conductive isolation layer ensures that the accuracy of the internal measuring unit is not affected in magnetic adsorption mode, guaranteeing the reliability of the measurement.

[0039] See Figure 2 and Figure 3The measuring unit is mounted inside the housing 1 via a universal joint structure. This universal joint structure allows the measuring axis of the measuring unit to adaptively adjust its posture when the housing 1 tilts, ensuring the stability of the measurement reference. To eliminate initial measurement errors introduced by uneven mounting surfaces, this embodiment employs a universal joint structure. This structure is implemented by two parts: first, a concave spherical mounting position is machined into the inner wall of the housing 1; second, a spherical adapter sleeve 3 is designed, whose outer surface has a spherical profile that matches the spherical mounting position. The core components of the entire measuring unit are integrated and encapsulated inside the spherical adapter sleeve 3. The core components of the entire measuring unit, namely the angle sensor 2, are integrated and encapsulated inside the spherical adapter sleeve 3. These core components are housed in a protective cavity formed by the angle sensor housing 21 and the angle sensor end cap 27. After assembly, the spherical adapter sleeve 3, like a ball head placed in a socket, can rotate freely within a certain angle range. When the device is adsorbed onto an inclined wall panel, regardless of the orientation of the housing 1, the internal measuring unit automatically adjusts to a perpendicular orientation under its own gravity, ensuring that its core measuring axis remains absolutely horizontal or vertical, serving as the zero-point reference for subsequent measurements. This invention, by employing this universal joint structure, decouples the measuring reference from the installation reference, making the measurement results unaffected by the flatness of the wall panel surface and the initial installation angle, fundamentally guaranteeing the absolute accuracy of the measurement and its reliability under complex working conditions.

[0040] The measuring unit includes a gravity pendulum mechanism and an angular displacement sensing component. The gravity pendulum mechanism is used to sense the direction of gravity, and the angular displacement sensing component is used to detect the angular displacement of the gravity pendulum mechanism relative to the housing 1. Inside the universal joint structure, the core of the measuring unit is a physical pendulum system. The gravity pendulum mechanism is the reference sensor for the direction of gravity, and it mainly consists of a lightweight, high-rigidity pendulum rod 5 and a metal pendulum ball 6 with a relatively large mass fixed to its end. The upper end of the pendulum rod 5 is firmly connected to a rotating shaft 26 via a fixing ring 4. To ensure that the pendulum system can overcome the resistance torque such as bearing friction and respond to small tilt angles, the mass m of the pendulum ball 6 needs to be calculated and must satisfy the formula: m ≥ T. total / (gLsinθ), where T total Let θ be the total resistance torque of the rotating shaft system, L be the effective length of the pendulum rod, g be the acceleration due to gravity, and θ be the minimum angle that the system can detect.

[0041] The angular displacement sensing component is used to accurately convert the physical angular displacement of the gravity pendulum mechanism into an electrical signal. In this embodiment, a non-contact magnetic encoder component is used. When the wall panel is tilted, the housing 1 fixed to the wall panel rotates accordingly, while the gravity pendulum mechanism remains vertical under the action of gravity. This relative motion causes the rotating shaft 26 fixed to the pendulum rod to rotate relative to the housing 1, and the angular displacement sensing component captures this rotation angle in real time.

[0042] This invention utilizes a gravity pendulum as a physical reference for sensing the absolute vertical direction, and combines it with high-precision angular displacement sensing technology to form a stable, reliable, and sensitive tilt measurement core, providing a fundamental guarantee for the high-precision performance of the device.

[0043] See Figure 2 The angular displacement sensing component includes a magnetic ring 23 fixed to the rotating shaft 26 and a magnetic sensor disposed on the housing 1; the geometric center of the magnetic ring 23 is not concentric with the rotation center of the rotating shaft 26, forming a preset eccentricity; the magnetic sensor is positioned offset relative to the geometric center of the magnetic ring 23.

[0044] To further improve measurement accuracy, the angular displacement sensing component of this embodiment has a specific structure. The component includes a multi-pole magnetized magnetic ring 23, which is fixed to a rotating shaft 26 and rotates synchronously with the shaft. A highly sensitive magnetic sensor is fixed to a circuit board 22 adjacent to the magnetic ring 23, and the circuit board 22 is in turn fixed to the housing 1.

[0045] This structure introduces a double eccentricity: First, during installation, the geometric center of the magnetic ring 23 does not coincide with the rotation center of the shaft 26, but rather has a preset eccentricity e. This eccentricity e can be designed based on the radius R of the magnetic ring 23, for example, satisfying e = R × (1 - cos(π / 16)). Second, the sensing point of the magnetic sensor is not aligned with the geometric center of the magnetic ring 23, but is offset by a specific distance relative to the geometric center of the magnetic ring. This offset distance is preferably half of the eccentricity e, i.e., e / 2. When the shaft 26 rotates slightly, this double eccentricity design causes the magnetic ring 23 to generate a nonlinear, amplified magnetic field gradient change near the magnetic sensor. Through this double eccentricity design, this invention effectively amplifies the change in magnetic field signal corresponding to angle changes, thereby significantly improving the resolution and sensitivity of angle measurement, enabling the device to identify and accurately measure minute tilt angle changes.

[0046] The rotating shaft 26 is supported by a pair of bearings 25; a spacer ring 24 is provided between the bearings 25, and the rotating shaft 26 is axially limited by a snap ring. The support structure of the rotating shaft 26 is very important to ensure that the gravity pendulum mechanism can swing freely without obstruction or wobbling.

[0047] Specifically, the rotating shaft 26 is supported on the frame of the measuring unit by two precision miniature bearings 25, which minimize rotational friction resistance. A precision-machined spacer ring 24 is fitted between the inner rings of the two bearings 25. The length of the spacer ring 24 precisely defines the distance between the two bearings, ensuring proper preload and stable operation. Furthermore, a retaining ring groove is machined at an appropriate position on the rotating shaft 26. The axial position of the rotating shaft 26 is precisely limited by installing a retaining ring, preventing axial movement during vibration or tilting. This invention, through the combination of high-precision bearings, spacer rings, and retaining rings, constitutes a highly stable, low-resistance rotating shaft support system. It eliminates radial and axial play in the rotating shaft, ensuring pure and sensitive movement of the oscillating mechanism, and is a necessary mechanical foundation for achieving high-precision measurement.

[0048] The intelligent feedback unit includes a display screen 10 for displaying tilt angle values, a buzzer for emitting audible prompts, and indicator lights for status indication. To provide construction personnel with intuitive and easy-to-understand calibration guidance, the intelligent feedback unit in this embodiment integrates multiple feedback modes.

[0049] It includes an LCD screen 10 located on the surface of the housing 1, capable of displaying the currently measured tilt angle value digitally in real time and with high accuracy. Simultaneously, it incorporates a buzzer whose beeping mode is controlled by an internal control module. When the wall panel tilt angle deviates significantly from the target angle, the buzzer emits an intermittent, frequency-varying alarm sound, with the frequency increasing as the deviation decreases, providing the operator with an audible sense of approach. When the tilt angle deviation Δθ is calibrated to within a very small preset threshold, calibration is complete; at this point, a green indicator light illuminates, and the buzzer switches to a continuous beep.

[0050] In addition, the housing 1 is equipped with a main button 12 for starting and stopping the equipment and for the adsorption function, as well as a level bubble 11 for rough positioning before installing the equipment. This utility model provides operators with comprehensive and multi-dimensional calibration information through coordinated feedback in three ways: digital, sound, and light. This allows the calibration process to be judged by sound and light alone, without having to keep an eye on the screen, greatly reducing the difficulty of operation and making high-precision calibration simple and intuitive.

[0051] An inertial damping block 13 is also provided inside the housing 1, and the inertial damping block 13 is connected to the inner wall of the housing 1 through elastic elements. Construction sites are often accompanied by vibration and impact. To protect the precision measuring unit inside, this embodiment adds a passive vibration damping system inside the housing 1. This system mainly includes an inertial damping block 13 with a relatively large mass, which is flexibly connected to the inner wall of the housing 1 through multiple elastic elements such as silicone buffer pads 14. When the entire device is subjected to a sudden impact or continuous vibration from the outside along with the wall panel, due to inertia, the inertial damping block 13 tends to maintain its original motion state and generate relative displacement with the housing 1. At this time, the silicone buffer pads 14 connecting the two will deform, thereby effectively absorbing and dissipating most of the vibration energy and preventing it from being transmitted to the internal measuring unit. By incorporating this passive damping system, the present invention significantly enhances the device's impact and vibration resistance, ensuring that the internal gravity pendulum mechanism remains stable even in construction environments. This guarantees the stability and reliability of the measurement data and improves the device's environmental adaptability and durability.

However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
