Description

Technical Field

[0002] Road surface misalignment, a common defect in concrete pavements, severely impacts pavement smoothness, service life, and overall project quality. This is especially true on newly paved asphalt concrete pavements, where misalignment not only detracts from the overall aesthetics but can also lead to cracking. While current road surface misalignment measurement technology has advanced to some extent, several shortcomings remain: most existing misalignment detection devices use wired connections, limiting the measurement range, increasing the complexity of on-site operations, and making cables susceptible to damage in complex or confined environments, affecting the continuity and accuracy of measurements. Furthermore, wired devices rely on external power supplies, limiting the time and location of measurement operations and increasing usage costs and maintenance difficulties in remote areas. In addition, regarding measurement accuracy, traditional visual judgment and steel tape measure methods are prone to significant errors due to human factors, while electronic measuring devices, although improving accuracy, are susceptible to environmental interference, affecting the accuracy of measurement results. The commonly used method of using a level and feeler gauge in engineering is time-consuming, inefficient, and has limited accuracy, failing to meet the demands of high-precision measurements.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] This embodiment provides an integrated wireless misalignment measurement device, such as... Figures 1 to 6 As shown, the misalignment measuring device mainly consists of a battery cover bracket 1, a contact rod 2, a level 3, a base 4, a gear slide 5, an encoder cover 6, a battery cover 7, an encoder gear 8, a guide rod 9, a guide rod spring 10, an encoder 11, a ring gear radial movement mechanism 12, a wireless communication module 13, a battery compartment 14, a copper ring 15, a battery compartment knob 16, and a plastic gasket 17. All components are compactly and stably integrated into the main body of the device, forming a highly integrated measuring system.

[0023] The battery cover bracket 1 and the battery cover 7 together form the external structure of the battery compartment 14, providing a safe storage space for the battery. The battery compartment knob 16 is designed on the battery cover 7, making it easy for users to open and close the battery compartment for battery replacement and maintenance.

[0024] like Figure 3-4As shown, the base 4 adopts a "C" - shaped design. Among them, the long surface serves as the main bearing surface, closely cooperating with the gear slide 5 to provide a stable support. The gear slide 5 presents a hollow cuboid structure, and the hollow groove inside it provides guidance for the annular gear radial movement mechanism 12.

[0025] The encoder 11 is of the model "P3015S", installed in the middle of the gear slide 5, and is directly connected to the annular gear radial movement mechanism 12 through the encoder gear 8. When the annular gear radial movement mechanism 12 undergoes a radial displacement, it will drive the encoder gear 8 to rotate, and then带动 the encoder 11 to rotate synchronously, reading and recording the displacement data in real - time and accurately, and converting it into a high - precision electrical signal for output.

[0026] One end of the contact rod 2 is fixedly connected to the bottom of the annular gear radial movement mechanism 12, and the other end is designed as a contact end, specifically used for precisely contacting the second misaligned surface, serving as a reference point for measurement, ensuring the accuracy and reliability of the measurement.

[0027] One end of the guide rod 9 is fixedly connected to the upper end surface of the base 4, and the other end penetrates through the upper end surface of the annular gear radial movement mechanism 12. A guide rod spring 10 is sleeved around the guide rod 9, and through its elastic force, a continuous and stable downward pressure is exerted on the annular gear radial movement mechanism 12. Ensure that when the second misaligned surface sinks, the annular gear radial movement mechanism 12 can adjust flexibly accordingly, keeping the contact rod 2 always in close contact with the second misaligned surface, so as to be able to respond to the displacement change of the misaligned surface in real - time and accurately.

[0028] The main body of the annular gear radial movement mechanism 12 is an annular hollow structure, and teeth are evenly distributed on the inner side surface. These teeth are precisely meshed with the encoder gear 8. It converts the radial displacement amount into a rotation amount, and through the stable guidance and support provided by the gear slide 5 and the guide rod 9, ensures that the annular gear radial movement mechanism 12 can move smoothly up and down with the undulation of the second misaligned surface, achieving high - precision misalignment measurement.

[0029] The wireless communication module 13 is of the model "BC20", supporting multiple communication protocols such as NB - IOT, Zigbee, and LoRa. It can select a suitable communication method according to the specific needs and application scenarios of users, enabling this device to easily access various Internet of Things platforms and data centers, realizing remote data transmission and monitoring functions.

[0030] The battery compartment 14 features an integrated annular copper ring 15 along its edge to enhance structural strength and electrical connection reliability. It is securely installed via precision screw holes, ensuring long-term stability. The battery compartment knob 16 employs a semi-circular handle design for easy user operation. Its rotation mechanism tightly locks the battery in place, preventing movement and ensuring stable power supply. A plastic gasket 17 is added between the knob and the battery compartment to provide cushioning protection, prevent loosening and wear, and enhance the battery compartment's seal, effectively isolating it from external interference.

[0031] In use, one side of the battery cover bracket 1 is fixed to the first misaligned platform. The tilt angle of the device is adjusted by observing the level 3. When the measuring device is operating, if the second misaligned platform is displaced, the elasticity of the guide rod spring 10 applies a continuous and stable downward pressure to the ring gear radial movement mechanism 12, ensuring that the contact between the contact rod 2 and the second misaligned platform always maintains high precision. As the contact rod 2 moves up and down, the ring gear radial movement mechanism 12 moves radially under the guidance of the gear slide 5. The teeth of the ring gear radial movement mechanism 12 drive the encoder gear 8 to rotate, which in turn causes the encoder 11 to rotate synchronously. The encoder 11 then reads and records this displacement data in real time, converts it into a high-precision electrical signal, and outputs it to the wireless communication module 13. The wireless communication module 13 then sends a signal to the external control unit to monitor the misalignment height change information.

[0032] Based on the efficient operation of a single device, when multiple measuring devices are deployed at the same measurement site, each responsible for measuring the displacement of different misaligned surfaces, these devices can work in parallel without interfering with each other. Each device's encoder 11 converts its measured displacement data into electrical signals and transmits them to the wireless communication module 13, which then transmits them to the external control unit. The external control unit receives, integrates, and analyzes the electrical signal data from each measuring device to obtain the overall displacement changes of each misaligned surface at the entire measurement site.

[0033] This multi-device collaborative working mode not only improves measurement efficiency but also enhances the comprehensiveness and accuracy of the measurements. By centrally processing and analyzing data from multiple measurement points, a more comprehensive understanding of the displacement distribution and changing trends of the misaligned platform can be achieved, providing strong support for subsequent engineering decisions and data analysis. Meanwhile, the wireless connection offers greater flexibility and convenience, eliminating the constraints of physical cables and allowing for more free deployment and movement of equipment, making it particularly suitable for complex or dynamically changing measurement environments.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; under the concept of this utility model, the technical features of the above embodiments or different embodiments can also be combined, and there are many other variations of different aspects of this utility model as described above. For the sake of brevity, they are not provided in detail; although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
