Description

Technical Field

[0001] This utility model relates to the field of road surface smoothness detection technology, and in particular to a road surface smoothness detection structure. Background Technology

[0002] In the actual operation of road surface smoothness inspection, the traditional three-meter-long straight rod plays a crucial role. This rod, typically made of high-strength aluminum alloy, is widely used due to its excellent resistance to deformation caused by its material properties. It provides a standard straight reference, and by directly comparing the rod with the actual road surface contour, the smoothness of the road surface can be intuitively reflected. With the aid of a feeler gauge, inspectors can accurately measure the minute gap between the bottom of the rod and the road surface. Based on this inspection data, and following established standards or specifications, a comprehensive evaluation of the road surface smoothness of the entire inspected section can be made.

[0003] However, while aluminum alloy straight rods are lightweight and easy to carry, they are prone to wobbling during feeler gauge measurements due to operational or environmental factors. This can lead to measurement errors and affect the accuracy of the final results. To address this issue, some inspectors opt for heavier straight rods, such as wooden ones. These rods, due to their weight, are less prone to wobbling, providing a more stable reference point during measurement and thus improving accuracy. However, the bulky size and weight of wooden straight rods limit their portability, making transportation and carrying difficult in situations requiring frequent changes to the inspection location, thus reducing work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a road surface smoothness detection structure to solve the problem that traditional heavy straight rods are inconvenient to carry.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A road surface smoothness detection structure includes: a measuring ruler and a moving component, wherein the measuring ruler is horizontally positioned and mounted on the moving component, and the moving component is capable of moving the measuring ruler on the road surface; a lifting component, wherein the lifting component is mounted on the moving component and connected to the measuring ruler, and the lifting component is capable of moving the measuring ruler up and down; and a rotating component, wherein the measuring ruler is rotatably connected to the lifting component via the rotating component to adjust the angle of the measuring ruler.

[0007] Based on the aforementioned technical means, this utility model, through the design of the movable component, allows the entire testing structure to be easily moved on the ground, eliminating the need for manual handling of heavy straight rods and thus greatly improving portability. Testing personnel can quickly push the equipment to the testing location, reducing physical exertion and improving work efficiency. The lifting component design allows the measuring ruler to be raised during movement and can be quickly switched from the raised to the lowered state, facilitating rapid commencement of testing work. Simultaneously, the precise control function of the lifting component ensures that the measuring ruler can be placed stably and accurately at the predetermined position, providing a solid foundation for subsequent measurement work. The rotating component allows the measuring ruler to be angled according to the road slope, keeping it nearly parallel to the road surface at all times, reducing measurement errors caused by road slope and further improving the reliability of the test results.

[0008] This invention combines the design of a moving component, a lifting component, and a rotating component, which not only solves the problem of the inconvenience of carrying traditional straight rods, but also improves the flexibility, accuracy, and applicability of testing.

[0009] Furthermore, the movable component includes a mounting base and casters, the casters being mounted on the bottom end of the mounting base to drive the mounting base to move; the lifting component is mounted on the mounting base.

[0010] Based on the aforementioned technical means, the design of the omnidirectional wheels enables the mobile components to move flexibly on various road surfaces, greatly reducing the labor intensity of inspection personnel who need to manually carry or drag the equipment.

[0011] Furthermore, the lifting assembly includes a guide assembly and a lifting block. The guide assembly is mounted on the mounting base and extends along a first direction. The lifting block is movably mounted on the guide assembly and can move along the first direction on the guide assembly. The measuring ruler is mounted on the lifting block, enabling the measuring ruler to move up and down.

[0012] Based on the above-mentioned technical means, this utility model, through the extension design of the guide component along the first direction, enables the lifting block to move smoothly and accurately in that direction, ensuring the stability and accuracy of the measuring ruler during lifting and lowering, thereby improving the accuracy of road surface smoothness detection.

[0013] Furthermore, the lifting assembly also includes a drive assembly, which is mounted on the guide assembly and connected to the lifting block. The drive assembly is used to drive the lifting block to move.

[0014] Based on the aforementioned technical means, the drive component allows inspectors to quickly and accurately adjust the position of the lifting block according to actual needs, enabling the measuring ruler to rapidly reach the required height and adapt to different measurement scenarios. Compared to manually raising or lowering the measuring ruler, operating the lifting block through the drive component significantly reduces the physical burden on inspectors.

[0015] Furthermore, it also includes an adjusting arm, one end of which is movably inserted through the lifting block and extends along a second direction, allowing the adjusting arm to move along the second direction; the other end of the adjusting arm is connected to the rotating assembly, so that the extension length of the rotating assembly can be adjusted during the movement of the adjusting arm.

[0016] The first direction and the second direction are perpendicular to each other.

[0017] Based on the aforementioned technical means, the introduction of the adjusting arm enables the functional components to be positioned in a second direction, which greatly enhances the flexibility of the entire detection structure and its adaptability to different road conditions. Whether in narrow spaces or complex terrain, the precise movement of the adjusting arm ensures that the functional components are in the optimal working position.

[0018] Furthermore, the rotating assembly includes a support frame, a rotating shaft, and a connector. The support frame is mounted on the other end of the adjusting arm. The rotating shaft is rotatably mounted on the support frame and extends along a third direction. One end of the connector extends movably through the rotating shaft and extends along the first direction. The other end of the connector is connected to the measuring ruler.

[0019] The first direction, the second direction, and the third direction are perpendicular to each other.

[0020] Based on the aforementioned technical means, during measurement operations, when it is necessary to lower the height of the lifting assembly to bring the measuring ruler into contact with the road surface, the structural feature of the connector, which is designed to movably pass through the pivot (specifically, the pivot is mounted on the connector in a sleeve manner), allows the pivot to move along the axial direction of the connector as the lifting assembly descends. This ensures that even if the height of the lifting assembly is continuously lowered, the measuring ruler can always maintain contact with the road surface, while avoiding the connector from breaking due to excessive force, thus ensuring the continuity of measurement and the structural safety of the connector.

[0021] Furthermore, one end of the connector is formed with a limiting member, which is used to abut against the rotating shaft to prevent the connector from falling off the rotating shaft.

[0022] Based on the above technical means, the limiting component in this utility model is used to abut against the rotating shaft, so that the lifting assembly can easily and stably lift the measuring ruler.

[0023] Furthermore, the measuring ruler includes a first ruler and a second ruler, the first ruler being mounted on the rotating assembly; the second ruler is detachably attached to one side of the first ruler.

[0024] Based on the aforementioned technical means, the length of the measuring rod can be flexibly adjusted according to actual measurement needs through the detachable and splicable second rod. When long-distance measurements are not required, the second rod can be detached from the first rod, making the entire measuring rod more compact, lightweight, and easy to carry and store.

[0025] Furthermore, the measuring ruler also includes a splicing assembly, through which the second ruler is detachably spliced ​​onto the first ruler.

[0026] Based on the aforementioned technical means, the detachable and modular design allows for individual maintenance and upgrades of each part of the measuring ruler. If a part is damaged or needs replacement, only the corresponding component needs to be replaced, rather than the entire measuring ruler. This reduces maintenance costs and extends the lifespan of the equipment.

[0027] Furthermore, it also includes a storage frame mounted on the movable component, the storage frame being used to prevent the second ruler from being disassembled.

[0028] Based on the aforementioned technical means, the introduction of the storage frame provides a dedicated storage space for the disassembled second ruler, preventing loss or damage that might result from careless placement. This greatly improves user convenience during the measurement process, making the operation smoother and more efficient.

[0029] The beneficial effects achieved by this utility model are:

[0030] This invention, through the design of the movable component, allows the entire testing structure to be easily moved on the ground, eliminating the need for manual handling of heavy straight rods and greatly improving portability. Testing personnel can quickly push the equipment to the testing location, reducing physical exertion and improving work efficiency. The lifting component allows the measuring ruler to be raised during movement and quickly switched from the raised to the lowered state, facilitating rapid commencement of testing work. Simultaneously, the precise control function of the lifting component ensures that the measuring ruler is placed smoothly and accurately at the predetermined position, providing a solid foundation for subsequent measurement work. The rotating component allows the measuring ruler to be angled according to the road slope, keeping it nearly parallel to the road surface at all times, reducing measurement errors caused by road slope and further improving the reliability of the test results.

To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The same or similar reference numerals correspond to the same or similar components. The terms describing positional relationships in the drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. Detailed Implementation

[0043] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific embodiments should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0045] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0046] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0047] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0048] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings.

[0049] like Figure 1 , Figure 3 and Figure 5 As shown, this embodiment proposes a road surface smoothness detection structure, including: a measuring ruler 1 and a moving component 2. The measuring ruler 1 is horizontally set and mounted on the moving component 2, which can drive the measuring ruler 1 to move on the road surface; a lifting component 3, which is mounted on the moving component 2 and connected to the measuring ruler 1, and can drive the measuring ruler 1 to move up and down; and a rotating component 5, which rotatably connects the measuring ruler 1 to the lifting component 3 to adjust the angle of the measuring ruler 1.

[0050] In actual use, adjust the height of the lifting component 3 to raise the measuring ruler 1. Activate the moving component 2 to move the measuring ruler 1 across the road surface. Adjust the moving speed and direction according to the testing requirements to ensure that the measuring ruler 1 covers the entire test section.

[0051] During the measurement process, lower the height of the lifting assembly 3 to maintain appropriate contact pressure between the measuring ruler 1 and the road surface. If the angle between the measuring ruler 1 and the road surface is found to be unsuitable, it can be adjusted by rotating the assembly 5. After adjusting the angle, ensure that the measuring ruler 1 can be stably maintained at the new angle for subsequent measurement work.

[0052] After measuring ruler 1 contacts the road surface, observe and record the location of the maximum gap between it and the road surface. Insert a feeler gauge into this maximum gap and gradually apply slight pressure until resistance is felt or the feeler gauge can just slide freely but cannot move easily. Read and record the size of the gap according to the accuracy of the feeler gauge's scale. After the test, process and analyze the collected data to obtain the evaluation result of the road surface smoothness.

[0053] This embodiment utilizes a movable component design, allowing the entire testing structure to be easily moved on the ground without the need for manual handling of heavy straight rods, thus greatly improving portability. Testing personnel can quickly push the equipment to the testing location, reducing physical exertion and improving work efficiency. The lifting component design allows the measuring ruler to be raised during movement and can be quickly switched from a raised to a lowered state, facilitating rapid commencement of testing work. Simultaneously, the precise control function of the lifting component ensures that the measuring ruler is placed smoothly and accurately at the predetermined position, providing a solid foundation for subsequent measurement work. The rotating component allows the measuring ruler to be angled according to the road slope, keeping it nearly parallel to the road surface at all times, reducing measurement errors caused by road slope, and further improving the reliability of the test results.

[0054] This embodiment combines the design of a moving component, a lifting component, and a rotating component, which not only solves the problem of the inconvenience of carrying traditional straight rods, but also improves the flexibility, accuracy, and applicability of the detection.

[0055] like Figure 1 and Figure 3 As shown, the movable component 2 includes a mounting base 21 and casters 22. The casters 22 are mounted on the bottom of the mounting base 21 to drive the mounting base 21 to move; the lifting component 3 is mounted on the mounting base 21.

[0056] The design of the casters 22 allows the mobile component 2 to move flexibly on various road surfaces, greatly reducing the labor intensity of inspection personnel who need to manually carry or drag the equipment.

[0057] To improve the overall structural stability, the mounting base 21 adopts a triangular structure design in this embodiment. As a classic and stable geometric shape, the triangle exhibits excellent load-bearing and stability properties in mechanics. This design allows the mounting base 21 to more stably support the entire detection structure when bearing the weight from the measuring ruler 1 and the lifting assembly 3, reducing measurement errors caused by shaking or tilting.

[0058] Meanwhile, the number of casters 22 is set to three, and the three casters 22 are respectively installed at the three corners of the mounting base 21 to not only ensure the balance of the mounting base 21 during movement, but also enhance its stability. Each caster 22 can independently provide support and steering functions, making the entire detection structure more stable during movement and reducing the risk of tipping over or loss of control due to uneven force on a single wheel.

[0059] It is worth mentioning that each caster wheel 22 in this embodiment is made of wear-resistant materials, such as polyurethane or nylon, to ensure smooth rotation and durability during long-term use.

[0060] like Figure 1 and Figure 3 As shown, the lifting assembly 3 includes a guide assembly 31 and a lifting block 32. The guide assembly 31 is mounted on the mounting base 21 and extends along a first direction. The lifting block 32 is movably mounted on the guide assembly 31 and can move along the first direction on the guide assembly 31. The measuring ruler 1 is mounted on the lifting block 32, so that the measuring ruler 1 can move up and down.

[0061] In this embodiment, the guide component 31 extends along the first direction, enabling the lifting block 32 to move smoothly and accurately in that direction. This ensures the stability and accuracy of the measuring ruler 1 during lifting and lowering, thereby improving the accuracy of road surface smoothness detection.

[0062] The guide component 31 is a guide rail structure, and the lifting block 32 is tightly and stably embedded in the guide rail. This allows the guide rail to not only accurately guide the lifting block 32 to move in the predetermined direction, but also to prevent misalignment. It provides a stable moving path for the lifting block 32, ensuring that it will not deviate from the track during movement, and effectively guaranteeing the accuracy and stability of the measurement.

[0063] like Figure 1 and Figure 3 As shown, the lifting assembly 3 also includes a drive assembly 33, which is mounted on the guide assembly 31 and connected to the lifting block 32. The drive assembly 33 is used to drive the lifting block 32 to move.

[0064] The drive assembly allows inspectors to quickly and accurately adjust the position of the lifting block 32 according to actual needs, enabling the measuring ruler 1 to rapidly reach the required height and adapt to different measurement scenarios. Compared to manually raising or lowering the measuring ruler 1, operating the lifting block 32 through the drive assembly 33 can greatly reduce the physical burden on inspectors.

[0065] In this embodiment, as Figure 1 and Figure 2 As shown, the drive assembly 33 includes a handwheel 331, a traction cable 332, and a fixed pulley 333. The fixed pulley 333 is mounted on the top of the guide assembly 31, and the handwheel 331 is mounted on one side of the guide assembly 31. The traction cable 332 is wound and collected inside the handwheel 331, and one end of the traction cable 332 can pass around the fixed pulley 333 and connect to the lifting block 32 inside the guide assembly 31. Rotating the handwheel 331 can release or retract the cable, causing the lifting block 32 to descend or rise.

[0066] Furthermore, to ensure the positioning of the lifting block 32 during movement, such as Figure 2 As shown, in this embodiment, a positioning hole 3311 is provided on the handwheel 331, and a positioning pin 334 is provided on one side of the guide component 31. The positioning pin 334 can be inserted into the positioning hole 3311 to lock the handwheel 331.

[0067] In addition, to enhance the safety and convenience of operation, this embodiment also provides anti-slip texture (not shown in the figure) on the handle of the handwheel 331. These anti-slip textures can increase the friction when the operator rotates the handwheel, effectively preventing accidental rotation due to slippage and ensuring precise control when adjusting the position of the lifting block 32.

[0068] like Figure 1 , Figure 3 and Figure 5 As shown, it also includes an adjusting arm 4, one end of which is movably inserted through the lifting block 32, and the adjusting arm 4 extends along the second direction so that the adjusting arm 4 can move along the second direction; the other end of the adjusting arm 4 is connected to the rotating component 5 so that the extension length of the rotating component 5 can be adjusted during the movement of the adjusting arm 4; the first direction and the second direction are perpendicular to each other.

[0069] The introduction of the adjusting arm 4 allows the functional components to be positioned in a second direction, which greatly enhances the flexibility of the entire detection structure and its adaptability to different road conditions. Whether in narrow spaces or complex terrain, the precise movement of the adjusting arm 4 ensures that the functional components are in the optimal working position.

[0070] like Figure 1 and Figure 3As shown, the rotating assembly 5 includes a support frame 51, a rotating shaft 52, and a connector 53. The support frame 51 is mounted on the other end of the adjusting arm 4. The rotating shaft 52 is rotatably mounted on the support frame 51 and extends along a third direction. One end of the connector 53 is movably inserted through the rotating shaft 52 and extends along a first direction. The other end of the connector 53 is connected to the measuring ruler 1. The first direction, the second direction, and the third direction are perpendicular to each other.

[0071] During measurement operations, when it is necessary to lower the height of the lifting assembly 3 to bring the measuring ruler 1 into contact with the road surface, the connecting member 53 is designed to movably pass through the rotating shaft 52 (specifically, the rotating shaft 52 is mounted on the connecting member 53 in a sleeve manner). This structural feature allows the rotating shaft 52 to move along the axial direction of the connecting member 53 as the lifting assembly 3 descends. This ensures that even if the height of the lifting assembly 3 is continuously lowered, the measuring ruler 1 can always maintain contact with the road surface. At the same time, it avoids the connecting member 53 from breaking due to excessive force, thereby ensuring the continuity of measurement and the structural safety of the connecting member.

[0072] To make it easier to understand, a rectangular coordinate system can be established, such as... Figure 1 As shown, the X direction is the second direction, the Y direction is the third direction, and the Z direction is the first direction.

[0073] In this embodiment, the support frame 51 is designed as a U-shaped structure with an upwardly curved section. The rotating shaft 52 is placed on the curved section of the support frame 51 and is limited by bolts directly above it. This ensures that the installation of the rotating shaft 52 on the support frame 51 is both stable and flexible, allowing it to rotate smoothly when needed, while preventing accidental displacement or detachment during use. The curved section design not only provides a good support surface but also optimizes the stress distribution of the rotating shaft 52, reducing the risk of wear or damage caused by stress concentration. Furthermore, the bolt-limiting method is simple and effective, easy to install and disassemble, and allows for adjustment of the tightness of the limit according to actual needs, thereby meeting the requirements of different application scenarios.

[0074] like Figure 3 and Figure 4 As shown, a limiting member 531 is formed at one end of the connector 53. The limiting member 531 is used to abut against the rotating shaft 52 to prevent the connector 53 from falling off the rotating shaft 52.

[0075] In this embodiment, the limiting member 531 is used to abut against the rotating shaft 52, so that the lifting assembly 3 can easily and stably lift the measuring ruler 1.

[0076] like Figure 5 As shown, the measuring ruler 1 includes a first ruler 11 and a second ruler 12. The first ruler 11 is mounted on the rotating assembly 5; the second ruler 12 is detachably attached to one side of the first ruler 11.

[0077] In this embodiment, the length of the measuring rod 1 can be flexibly adjusted according to actual measurement needs through the detachable and splicable second rod 12. When long-distance measurement is not required, the second rod 12 can be detached from the first rod 11, making the entire measuring rod 1 more compact and lightweight, and easier to carry and store.

[0078] like Figure 5 As shown, the measuring ruler 1 also includes a splicing component 13, and the second ruler 12 is mounted on the first ruler 11 in a detachable manner via the splicing component 13.

[0079] The detachable, modular design allows for individual maintenance and upgrades of each part of the measuring ruler 1. If a part is damaged or needs replacement, only the corresponding component needs to be replaced, rather than the entire measuring ruler. This reduces maintenance costs and extends the lifespan of the equipment.

[0080] In this embodiment, the splicing component 13 includes a splicing groove and a splicing protrusion. The splicing groove and the splicing protrusion are compatible (i.e., the splicing protrusion can be embedded in the splicing groove). Both ends of the first ruler 11 have splicing grooves, and one end of the second ruler 12 has a splicing groove, while the other end is provided with a splicing protrusion. This allows the measuring ruler 1 to be flexibly combined by a first ruler 11 and several second rulers 12 connected to its two ends, greatly expanding the measurement range.

[0081] To further enhance the connection stability between the first ruler 11 and the second ruler 12 and prevent the second ruler 12 from accidentally detaching from the first ruler 11 during measurement, this embodiment specifically adds a bolt connection structure at the connection point. This structure not only improves the connection strength but also provides users with additional safety assurance, ensuring that the measuring ruler 1 maintains stable performance under various measurement environments.

[0082] like Figure 1 , Figure 3 and Figure 5 As shown, it also includes a storage frame 6, which is mounted on the movable component 2 and is used to prevent the second ruler 12 from being disassembled.

[0083] The introduction of the storage box 6 provides a dedicated storage space for the disassembled second ruler 12, preventing loss or damage that might result from careless placement. This greatly improves user convenience during the measurement process, making the operation smoother and more efficient.

[0084] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
