[0025] To make the purpose, technical scheme and advantages of the embodiments of the present disclosure more clear, below, the embodiments of the present disclosure are further described in detail in combination with examples and drawings, and the schematic embodiments and their descriptions are only used to explain the embodiments of the present disclosure, and not as a limitation on the embodiments of the present disclosure.

[0026] As Figure 1 shown, the wall thickness measuring device for building structure safety appraisal according to the present application includes probe 1, measuring rod 2, sliding block 3, support frame 4 and range finder 5 and other key components. These components are connected through reasonable mechanical design and connection form, ensuring that the device has high accuracy and reliability when measuring the wall thickness.

[0027] The main front contact component of the device is probe 1. One end of probe 1 is designed to fit the surface of different shaped walls, and the side is equipped with an elastic buffer layer 11, which is made of flexible polyurethane rubber or similar materials to ensure uniform pressure on the measured wall and reduce data deviation caused by uneven contact surface. A multi-point contact sensor array 12 is arranged inside the end, which is composed of several micro pressure sensing units. Each sensing unit independently collects pressure change information from the contact interface, and after weighted average calculation by the signal processing unit, it provides more accurate and stable detection results, thereby improving the accuracy of measurement. Probe 1 is directly linked to the sliding block 3 part through a fixed mechanical interface at one end, and maintains close cooperation to prevent lateral displacement.

[0028] The measuring rod 2 is made of high-strength stainless steel or other strong and flexible metal materials. Its outer diameter size is determined according to the actual use, but it needs to consider sufficient strength to bear external load. The two ends of this part are respectively installed with a limiting structure to limit the maximum movement range of the probe 1 and its connected mechanism, prevent excessive stretching from causing damage to the instrument, and ensure that the internal circuit and components are intact to transmit data to the reading terminal at any angle.

[0029] The slider 3 forms an adjustable structure around the outer surface of the measuring rod 2, and through delicate processing, a close and smooth motion relationship is formed between the two. In order to achieve this, the slider 3 is made of aluminum alloy or engineering plastic components with spiral texture on the inside, and the position adjustment of the probe 1 is flexibly fixed by using screw locking mechanism or other quick buckle solutions, ensuring that it can adapt to the requirements of various wall thickness changes, so that the probe 1 can smoothly approach the wall surface within a large stroke range and be locked at the ideal position, ensuring good sealing to avoid environmental factors interfering with detection accuracy.

[0030] The support frame 4 is designed asymmetrically to increase the stability of placement. The shorter side is used to support the ground or plane to maintain balance, while the longer side is used to approach the building facade and serve as an auxiliary reference point to mark the wall boundary, facilitating the determination of the specific test area range in subsequent operations. At the same time, this part should have high orthogonality and anti-seismic and anti-toppling ability in the vertical direction to resist the influence of external vibration on the final reading.

[0031] In addition, the support frame 4 is equipped with a specially designed range finder 5 at the top. This electronic component is arranged on the same axis of the aforementioned structure and shares the center line position with the measuring rod 2. Through built-in laser, ultrasonic, and other non-contact methods, the probe automatically captures the difference from the initial zero point to the current contact value, and after mathematical model algorithm conversion, it intuitively reflects the actual geometric parameters of the corresponding wall. Since this design scheme does not rely on traditional mechanical motion to complete the quantization output process, it greatly overcomes the risk problems caused by human error and significantly improves the work efficiency.

[0032] A wall thickness measuring device for building structure safety appraisal solves the problem of thickness reading deviation through several key links:

[0033] Firstly, through special design of the probe 1, such as setting up elastic buffer layer 11 and multi-point contact sensor array 12, the error caused by surface minor flaws is effectively reduced, and the measurement accuracy is improved.

[0034] Secondly, the adjustment mechanism composed of the measuring rod 2 and the sliding block 3 allows the operator to easily position the probe 1 in the most suitable place, ensuring uniform pressure distribution during measurement and enhancing the reliability of the measurement.

[0035] Finally, the use of the distance meter 5 further enhances the stability and automation of the system. By accurately obtaining the distance moved by the probe 1, it not only eliminates the uncertainty caused by manual reading, but also provides an instant feedback mechanism for calibration and verification of data. Overall, the combination of these comprehensive measures greatly improves the authenticity and accuracy of the wall thickness measurement results.

[0036] As shown in Figure 4 In one embodiment, the elastic buffer layer 11 of the wall thickness measuring device for building structure safety appraisal of the present application contains a gas pressure adaptive cushion 13. The design of the gas pressure adaptive cushion 13 ensures uniform pressure distribution on the contact area between the probe 1 and the wall. By automatically adjusting the pressure in local areas, this design significantly improves the fitting quality of the contact interface, further enhancing the accuracy and repeatability of the thickness measurement. The gas pressure adaptive cushion 13 is composed of flexible airbags that can quickly adapt to various uneven surfaces and maintain stable force application conditions according to the different convex and concave features of the wall surface contacted by the probe 1, avoiding pressure concentration or unevenness caused by external force changes.

[0037] For example, during the manufacturing process, small-sized, independently encapsulated and interconnected inflatable micro-airbag units made of flexible materials can be pre-embedded in the elastic buffer layer 11 to form the gas pressure adaptive cushion 13. When the probe 1 contacts the wall surface, these airbags deform under external pressure and transfer internal gas, achieving self-regulation function while maintaining overall elasticity, thereby making the stress during the entire measurement process more stable. Through the combination of this special structural design and technical solution, the measuring device not only adapts to different types and shapes of wall texture, but also effectively ensures the consistency and stability of the operation.

[0038] As shown in Figure 3 In one embodiment, the spacing between the sensing units of the multi-point contact sensor array 12 of the wall thickness measuring device for building structure safety appraisal of the present application is reduced to not more than 1 millimeter. This feature allows the measuring device to significantly improve the response speed and measurement accuracy for different wall textures when measuring the wall thickness. Specifically, the dense arrangement of sensing units in the sensor array ensures that even in the face of small surface texture changes or material differences, it can accurately capture weak pressure changes, significantly reducing pressure transmission errors caused by uneven surfaces. In addition, the small gap between the sensing units helps to further improve the spatial resolution of the sensor array, so that the stress distribution in each millimeter area can be accurately recorded and reflected.

[0039] Specifically, the multi-point contact sensor array 12 installed inside the probe 1 near the contact surface has an extremely high density. This high-density sensor array is prepared using miniaturization technology, with individual sensing units uniformly distributed and spaced within 1 mm. To ensure the realization of high resolution and maintain stable performance, the sensing units are connected to the signal processing circuit through flexible wires and encapsulated in a solid and corrosion-resistant protective layer. At the same time, to deal with the influence of possible heterogeneous structures in the wall surface layer, the sensor array is closely combined with the elastic buffer layer 11, together forming the ability to apply constant and uniform pressure to the wall, thereby ensuring accurate and reliable reading output. For example, during actual operation, as the probe gradually approaches the wall until fully adhering to the surface, the multi-point contact sensing system quickly senses the pressure changes at each part and transmits these data in real time to the distance meter 5, ultimately forming complete and accurate wall thickness data.

[0040] As shown in Figure 3 In one embodiment, the elastic buffer layer 11 of the wall thickness measuring device for building structure safety appraisal of the present application is also provided with a soft sealing strip 14 around the edge. The sealing strip is installed around the contact surface of the elastic buffer layer 11 and the wall. The soft sealing strip 14 is made of materials with good flexibility and elasticity, and its purpose is to prevent external air or particles from entering the gap between the probe 1 and the wall, ensuring the normal operation of the internal mechanism during measurement. The design of the soft sealing strip 14 not only plays a role in dust and gas prevention, but also maintains good sealing performance between the measurement interface and the wall. This sealing design can reduce the reading distortion caused by the deformation difference of the probe 1 caused by the change in wall thickness under the action of different air pressures.

[0041] In addition, the sealing strip is fixed by adhesion or embedded installation at the peripheral position of the elastic buffer layer 11. Specifically, an adaptive slot or groove is provided around the elastic buffer layer 11, and the pre-formed sealing strip is embedded here. This installation method ensures that there is no gap between the sealing strip and the buffer layer, further enhancing the overall stability and reliability of the device.

[0042] For example, in specific implementation, the soft sealing strip 14 can be made of thermoplastic rubber material and adhered to the outer periphery of the elastic buffer layer 11. To enhance the connection strength and durability, a suitable sealant can be pre-applied at the contact interface. When the probe 1 of the measuring device is attached to the wall surface, the sealing strip will be subjected to appropriate pressure and will deform moderately, effectively filling any fine gaps between the probe 1 and the wall surface, ensuring the air tightness and cleanliness of the test environment.

[0043] As shown in Figure 1 and Figure 2As shown, in one embodiment, two sets of electric push rods 6 are symmetrically installed at the bottom of the support frame 4 of the wall thickness measuring device for building structure safety assessment according to this application. These two sets of electric push rods 6 are located on both sides of the bottom of the support frame 4, ensuring the entire device maintains balance and stability on different ground surfaces. This symmetrical installation design also provides the measuring mechanism with height adjustment capabilities; the height of the device can be flexibly changed by operating the electric push rods 6, thereby adapting to the measurement needs at different wall heights.

[0044] In this embodiment, a movable frame 7 is connected to the bottom end of the electric actuator 6 to facilitate the displacement of the entire device. This connection not only ensures the overall stability of the structure but also does not affect the height adjustment function of the electric actuator 6. Specifically, the movable frame 7 can bear and transmit the thrust or pull force generated by the electric actuator 6 to the ground, while providing a stable moving platform to facilitate moving the measuring device to a suitable position for measurement.

[0045] A touch panel 8 is fixedly installed at the upper center of the mobile frame 7. The touch panel 8 is the main interface for user interaction with the device. It can not only control the device's start, stop, and other operating commands, but also intuitively display measurement results and other operating parameters. This component's design allows users to obtain real-time feedback information while operating the device.

[0046] For example, when a user needs to measure the thickness of walls at different heights, they can activate the electric actuator 6 by operating the touch panel 8. The electric actuator 6 will then extend and retract according to a predetermined program, changing the height of the support frame 4 relative to the ground, thereby adjusting the height of the probe 1 to align with the designated area and completing the multi-point wall thickness measurement task. The movable frame 7 easily moves and positions the entire device via bottom casters, ensuring accurate measurement every time.

[0047] like Figure 3 As shown, in one embodiment, the elastic buffer layer 11 of the wall thickness measuring device for structural safety assessment of this application employs a zone control technology, dividing the elastic buffer layer 11 into four independent pressure zones. Each pressure zone has a different hardness level to adapt to different measurement needs and provide the most suitable support strength. This approach avoids the problem of poor overall performance that may be caused by a single hardness material, thereby improving the accuracy and reliability of wall thickness measurement. In practical applications, the hardness difference between different areas helps to better adapt to irregular surfaces and ensures that the entire probe 1 achieves maximum area contact with the wall surface.

[0048] The elastic buffer layer 11 is located at the contact end of the probe 1 and covers the side of the multi-point contact sensor array 12, ensuring effective spacing between the two. Through this layout, while maintaining sensor sensitivity, changes in the direct force acting on the probe 1 and sensor due to uneven wall material can be reduced, indirectly improving the quality of test data. The specific division of each pressure zone of the elastic buffer layer 11 is designed and set according to various situations that may occur on the detection surface.

[0049] Specifically, in terms of technology, different hardness levels can be achieved through pre-installed materials or built-in air or liquid chambers. For example, the outermost part of the wall surface is made of a soft polymer buffer unit as the first pressure level; the inner area gradually increases in hardness, and harder rubber or sponge can be used to build the second and third levels of hardness support; finally, the center point is a support body with higher rigidity, constituting the fourth level of support system, ensuring the overall stability of the device and its flexibility to adapt to different environmental needs. The natural connection between the regions by the small transition layer ensures the continuity of the structure and the consistency of the mechanical transmission.

[0050] As shown in Figure 1 and Figure 3 , in one embodiment, the probe 1 of the wall thickness measuring device for building structure safety appraisal of the present application is provided with an angle adjustment mechanism 21 on the outside. The angle adjustment mechanism 21 is used to make the probe 1 deflect left and right within a certain range under the action of a damping shaft. This not only optimizes the fit between the probe 1 and the wall, but also effectively reduces the measurement deviation caused by inclined pressure.

[0051] The angle adjustment mechanism 21 is installed between the probe 1 and the measuring rod 2, and is tightly connected through mechanical connection. The structure is composed of elastic elements, guide plates and rotation limiters. Specifically, one end of the damping shaft is connected to the elastic elements in the angle adjustment mechanism 21, which can make the probe 1 adjust the inclination angle in real time according to the surface condition of the wall. The guide plate is responsible for providing rotation support and maintaining the appropriate movement path. The rotation limiter is used to limit the maximum allowed angle range to protect the device and maintain accuracy.

[0052] For example, in actual application, the maximum swing range of the probe 1 can be controlled by changing the characteristics of elements such as springs or adjusting the position of limit blocks, etc., to adapt to the needs of walls of different thicknesses and shapes. During the measurement operation, the user only needs to place the probe 1 close to the target wall and apply a moderate pushing force to trigger the automatic angle matching process, achieving accurate and reliable wall thickness reading function.

[0053] As shown in Figure 1 and Figure 2As shown in FIG. 1, in one embodiment, the sliding block 3 of the wall thickness measuring device for building structure safety appraisal of the present application is equipped with an electric micro-screw rod 31 for precisely controlling the movement of the probe 1. This design sets the movement path of the probe 1 through software programming, ensuring that it always maintains a vertical and stable movement trajectory during operation, eliminating the instability of positioning caused by human operation and further improving the measurement accuracy. The design of the sliding block 3 equipped with the electric micro-screw rod 31 not only improves the positioning accuracy of the probe 1, but also makes the device more easily automated and batch used, providing a reliable hardware foundation for efficient quality detection.

[0054] The sliding block 3 is sleeved on the outside of the measuring rod 2 and connected with the probe 1. The electric micro-screw rod 31 is assembled in the sliding block 3 and fixed therewith, driven by electricity to drive the probe 1 connected with the sliding block 3 to move up and down. The design of the electric micro-screw rod 31 realizes precise positioning, ensuring that the movement of the probe 1 can strictly follow the preset program.

[0055] For example, in a specific application scenario, the technician can set the distance between the measuring points and the specific parameters of each displacement through the software interface, and the electric micro-screw rod 31 drives the sliding block 3 and the probe 1 to move accurately according to the specified interval. The entire control system continuously monitors the running state of the probe 1 and the collected data feedback information, and then dynamically adjusts to maintain the best working state. The fine control of the movement of the probe 1 by the electric micro-screw rod 31 is a key factor in achieving stability and accuracy under complex wall conditions.

[0056] As shown in FIG. 1, in one embodiment, the sliding block 3 of the wall thickness measuring device for building structure safety appraisal of the present application is equipped with an electric micro-screw rod 31 for precisely controlling the movement of the probe 1. This design sets the movement path of the probe 1 through software programming, ensuring that it always maintains a vertical and stable movement trajectory during operation, eliminating the instability of positioning caused by human operation and further improving the measurement accuracy. The design of the sliding block 3 equipped with the electric micro-screw rod 31 not only improves the positioning accuracy of the probe 1, but also makes the device more easily automated and batch used, providing a reliable hardware foundation for efficient quality detection. Figure 1 Figure 2 As shown in FIG. 1, in one embodiment, the sliding block 3 of the wall thickness measuring device for building structure safety appraisal of the present application is equipped with an electric micro-screw rod 31 for precisely controlling the movement of the probe 1. This design sets the movement path of the probe 1 through software programming, ensuring that it always maintains a vertical and stable movement trajectory during operation, eliminating the instability of positioning caused by human operation and further improving the measurement accuracy. The design of the sliding block 3 equipped with the electric micro-screw rod 31 not only improves the positioning accuracy of the probe 1, but also makes the device more easily automated and batch used, providing a reliable hardware foundation for efficient quality detection.

[0057] In order to improve the accuracy of positioning and the initial contact state between the device and the wall surface, the auxiliary correction wheel 41 is designed to keep the device balanced and stably close to the wall surface during fine adjustment. When the operator moves the entire wall thickness measuring device close to and lightly touches the wall, the angle and flatness can be adjusted through the small range of rotation of the auxiliary correction wheel 41, so that a more ideal contact position can be selected, avoiding reading errors caused by initial uneven contact and ensuring the accuracy of the basic value during subsequent in-depth measurement.

[0058] ​For example, the device uses a flexible connecting member to connect the auxiliary correction wheel 41 and the support frame 4. The flexible connecting member allows the auxiliary correction wheel 41 to float up and down within a certain range to cope with small-scale protrusions or depressions that may exist on different wall surfaces. At the same time, the device restricts the direction in which the auxiliary correction wheel 41 rolls, so that it can only move slightly in a direction perpendicular to the wall surface, ensuring that the rolling wheel can be stopped in time after the optimal plane is found, and the measurement posture is fixed. In addition, the correction wheel surface material is selected to be rubber or other high-friction coefficient materials with good friction characteristics, ensuring that even in the face of a relatively smooth wall surface, it has strong gripping ability, effectively reducing the risk of relative slipping.

[0059] Specifically, the probe 1 can be attached to the wall surface, one end of the probe 1 is provided with an elastic buffer layer 11, which ensures uniform distribution of pressure on the entire contact area, making the measurement more accurate. At this time, the multi-point contact sensor array 12 inside the probe 1 near the contact surface will sense the contact information and transmit signals. The measuring rod 2 provides mechanical support and transmits measurement data, while the sliding block 3 is sleeved outside the measuring rod 2 and connected with the probe 1, which can slide on the measuring rod 2 to adjust the position of the probe 1, so that it is closely attached to the wall. The support frame 4 serves as the main support for the entire measurement mechanism, ensuring that the measurement mechanism is in a stable vertical state, and one end of the support frame 4 serves as a positioning point for one side wall of the wall, that is, one side of the support frame 4 and the elastic buffer layer 11 are in contact with the two sides of the wall respectively to measure the thickness of the wall. The distance meter 5 fixedly arranged on the support frame 4 is coaxially arranged with the measuring rod 2, which obtains the moving distance of the probe 1 by electronic means and calculates the thickness of the wall. These processes work together to ultimately achieve accurate determination of the thickness of the wall.
