Description

Technical Field

[0001] This utility model belongs to the field of flatness detection technology, and more specifically, it relates to a traffic road flatness detection device. Background Technology

[0002] The smoothness of a road surface directly affects its structural stability and durability. Road smoothness testing devices can accurately pinpoint the location of road defects such as bumps and ruts, providing a scientific basis for road maintenance. This process not only avoids the waste of resources caused by blind maintenance but also reduces the high costs of large-scale repairs later by intervening in potential problems in advance, thus improving the overall efficiency and sustainability of the road network. However, traditional road smoothness testing devices are limited in function, only capable of detecting a single smoothness index. This makes it difficult to meet the diverse needs of modern road maintenance management. They cannot simultaneously detect other key defect indicators such as rut ​​depth, crack width, and structural depth. This results in maintenance work focusing only on surface smoothness repair, failing to fundamentally eliminate defects and ultimately reducing the quality of road maintenance. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a traffic road smoothness detection device. This addresses the issue that existing traditional road smoothness detection devices have limited functionality, only detecting smoothness and failing to simultaneously detect indicators such as rut ​​depth, crack width, and structural depth. Consequently, maintenance only repairs surface smoothness, making it difficult to eradicate defects and reducing the quality of road maintenance.

[0004] The purpose and effectiveness of this utility model's traffic road smoothness detection device are achieved through the following specific technical means:

[0005] A road surface smoothness detection device includes a U-shaped mounting frame. A mounting groove is provided at the top of the mounting frame, through which a control module passes. A display is also mounted within the mounting groove and is electrically connected to the control module. An infrared detector is also provided on one side of the mounting frame and is electrically connected to the control module. Multiple sets of mounting portions and multiple sets of clips and slots are evenly arranged within the mounting frame. Connecting frames are rotatably mounted within the mounting portions. Distance sensors are mounted within each of the clips and slots, and each of the distance sensors is connected to the control module via a connector. An assembly is also connected to the connecting frame. A positioning rod is rotatably mounted at the top of the assembly. A positioning plate is also provided within the mounting frame. The positioning plate has through holes corresponding to the clips and slots, and the positioning rod passes through the through holes.

[0006] The above technical solution further includes: a mounting platform is fixedly connected to one side of the mounting frame, and the infrared detector is installed in the mounting platform; two sets of connecting rods for connecting the drive device are also arranged opposite each other on the mounting frame near the mounting platform; and multiple sets of moving wheels are also provided at the bottom of the mounting frame.

[0007] The above technical solution further includes that the mounting frame is evenly provided with cleaning components near the bottom of the multiple sets of moving wheels, and the top of the cleaning components is provided with multiple sets of mounting components, and the cleaning components are detachably connected to the mounting frame through the multiple sets of mounting components.

[0008] The above technical solution further includes that the connecting frame is L-shaped, and a first connecting member and a second connecting member are respectively provided at both ends of the connecting frame. The first connecting member and the second connecting member are rotatably disposed in the mounting part. The assembly is rotatably disposed in the second connecting member. The first connecting member, the second connecting member, the mounting part, and the assembly are all fixed by bolts.

[0009] The above technical solution further includes that the top of the assembly is provided with a combination groove, and two sets of mounting holes are provided between the two opposite inner sides of the combination groove. The bottom end of the positioning rod is also provided with a mounting post corresponding to the two sets of mounting holes. The positioning rod is rotatably disposed in the mounting hole of the assembly through the mounting post.

[0010] The above technical solution further includes that a return spring is provided between the assembly and the positioning plate, and the return spring is sleeved on the positioning rod.

[0011] The above technical solution further includes that the bottom end of the assembly is provided with a positioning groove, and a driven ground contact wheel is inserted in the positioning groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The device integrates an infrared detector and multiple distance sensors, enabling simultaneous detection of various indicators such as road smoothness, rut depth, and crack width. The infrared detector connects to the control module, and the distance sensors connect to the control module via connectors. The different sensors work together to acquire multi-dimensional data, providing a comprehensive basis for maintenance and avoiding the need to merely repair surface smoothness, thus facilitating the eradication of defects.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example:

[0025] like Figures 1 to 7As shown, this utility model provides a traffic road smoothness detection device, including a U-shaped mounting frame 1. The top of the mounting frame 1 is provided with a mounting groove, through which a control module 2 passes. A display 3 is also installed in the mounting groove, and the display 3 is electrically connected to the control module 2. An infrared detector 4 is also provided on one side of the mounting frame 1, and the infrared detector 4 is electrically connected to the control module 2. Multiple sets of mounting parts 101 and multiple sets of clips and slots 102 are evenly arranged inside the mounting frame 1. A connecting frame 103 is rotatably arranged in the multiple sets of mounting parts 101. Distance sensors 5 are installed in each of the multiple sets of clips and slots 102. The multiple sets of distance sensors 5 are connected to the control module 2 through connectors. An assembly 104 is also connected to the connecting frame 103. A positioning rod 105 is rotatably arranged at the top of the assembly 104. A positioning plate 106 is also provided inside the mounting frame 1. The positioning plate 106 has through holes corresponding to the clips and slots 102, and the positioning rod 105 passes through the through holes. The control module 2 is installed through the mounting slot at the top of the mounting bracket 1, and the display 3 is installed therein and electrically connected to the control module 2, forming a data processing and display unit. The detection data from the infrared detector 4 and multiple sets of distance sensors 5 are directly transmitted to the control module 2, processed, and displayed in real time on the display 3, reducing data transfer steps and realizing the integration of detection data acquisition, processing, and presentation; the infrared detector 4 can be the IL-065 model.

[0026] Multiple distance sensors 5 are mounted in the slots 102 of the mounting bracket 1, with their detection ends facing the top of the positioning rod 105. During detection, the bottom end of the positioning rod 105 is rotatably connected to the assembly 104, and its top end passes through the through hole of the positioning plate 106. Due to the unevenness of the road surface, the positioning rod 105 floats up and down along the through hole of the positioning plate 106. The distance sensors 5 continuously monitor the change in distance from the top of the positioning rod 105 and transmit the data to the control module 2. The control module 2 calculates and analyzes the distance data collected by the multiple distance sensors 5 to obtain the road surface smoothness value, and presents the data on the display 3. The distance sensor 5 can be the IX-360 model; the control module 2 can be the OPT-3101 model.

[0027] An infrared detector 4 is installed on one side of the mounting bracket 1, transmitting the detection signal to the control module 2 via an electrical connection. Multiple sets of clips and slots 102 within the mounting bracket 1 hold distance sensors 5, each connected to the control module 2 via a connector. During operation, the infrared detector 4 and the multiple sets of distance sensors 5 operate synchronously, simultaneously collecting data on various road indicators. This data is then aggregated and processed by the control module 2 to meet the diverse detection needs of road maintenance.

[0028] like Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, a mounting platform 201 is fixedly connected to one side of the mounting frame 1, and the infrared detector 4 is fitted inside the mounting platform 201. Two sets of connecting rods 202 for connecting the drive device are also arranged opposite each other on the mounting frame 1 near the mounting platform 201. Multiple sets of casters 203 are also provided at the bottom of the mounting frame 1. Cleaning components 301 are evenly distributed at the bottom of the mounting frame 1 near the multiple sets of casters 203. Multiple sets of mounting components 302 are provided at the top of the cleaning components 301, and the cleaning components 301 are detachably connected to the mounting frame 1 through the multiple sets of mounting components 302. The mounting platform 201 on one side of the mounting frame 1, where the infrared detector 4 is fitted, clearly defines the installation position, ensures a fixed detection direction and angle, and maintains consistent detection data. The mounting platform 201 provides physical support to prevent the detector from shifting or shaking during detection, ensuring accurate detection results.

[0029] Mounting frame 1 is equipped with two sets of connecting rods 202 for connecting external drive equipment to realize mechanized movement of the device; bottom moving wheels 203 provide rolling support, reduce the movement resistance of the device, and, in conjunction with the drive equipment, enable the device to move quickly on the road, improve detection efficiency, and adapt to the detection needs of different road sections; at the same time, a cleaning component 301 is provided at the bottom of mounting frame 1, which can be detachably connected through mounting component 302. The cleaning component 301 is installed before detection, and when moving, the cleaning component 301 contacts the road surface to remove fallen leaves, gravel and other debris; after detection, the cleaning component 301 is removed for easy storage and maintenance, and to prevent debris from affecting the detection accuracy of distance sensor 5 and positioning rod 105, ensuring that the detection data truly reflects the road surface smoothness.

[0030] like Figure 1 , Figure 3 and Figure 5 As shown, the connecting frame 103 is L-shaped, with a first connecting member 401 and a second connecting member 402 at each end. The first connecting member 401 and the second connecting member 402 are rotatably mounted within the mounting portion 101, and the assembly 104 is rotatably mounted within the second connecting member 402. The first connecting member 401, the second connecting member 402, the mounting portion 101, and the assembly 104 are all fixed with bolts. The first connecting member 401 and the second connecting member 402 at both ends of the L-shaped connecting frame 103 can rotate within the mounting portion 101, and the assembly 104 can rotate within the second connecting member 402, forming multiple degrees of rotational freedom. During testing, the angles of the connecting frame 103 and the assembly 104 can be adjusted by rotation according to the road slope and undulation, ensuring that the positioning rod 105 and the distance sensor 5 maintain the optimal testing posture, adapting to different road condition testing needs.

[0031] The first connecting piece 401 and the second connecting piece 402 are fixed to the mounting part 101 and the assembly 104 by bolts. Before testing, the angle can be adjusted as needed and the bolts tightened to ensure that the connecting frame 103 and the assembly 104 are fixed in position during testing, preventing vibration and displacement from affecting the detection accuracy of the distance sensor 5. After testing or during device maintenance, the bolts can be unscrewed to disassemble the relevant components for easy repair and replacement. The connecting frame 103, as an intermediate component, connects to the mounting part 101 at one end and to the assembly 104 at the other end, connecting the distance sensor 5, the positioning rod 105, and the main body of the mounting frame 1. During moving testing, road surface undulations cause the assembly 104 and the positioning rod 105 to move, and the displacement is transmitted to the distance sensor 5 through the connecting frame 103, ensuring that the sensor accurately captures the road surface smoothness change data.

[0032] like Figure 1 , Figure 3 and Figure 5 As shown, the top of the assembly 104 has a combination groove, and two sets of mounting holes are also formed between the two opposite inner surfaces of the combination groove. The bottom of the positioning rod 105 is also provided with a mounting post 501 corresponding to the two sets of mounting holes. The positioning rod 105 is rotatably mounted in the mounting hole of the assembly 104 via the mounting post 501. The mounting post 501 is inserted into the mounting hole of the assembly 104, forming a fulcrum for the rotation of the positioning rod 105. During detection, road surface undulations cause the positioning rod 105 to float up and down, and the mounting post 501 restricts its horizontal displacement, ensuring that the top of the positioning rod 105 always faces the distance sensor 5 vertically. The distance sensor 5 continuously monitors the distance between itself and the top of the positioning rod 105. The mounting post 501 maintains a vertical relationship to ensure stable distance data acquisition and avoid data errors caused by angular deviations. This provides reliable data support for the control module 2 to accurately calculate the road surface smoothness. At the same time, the mounting post 501 cooperates with the mounting hole to limit the lateral displacement of the positioning rod 105, ensuring that the positioning rod 105 remains stable during vertical floating and avoiding shaking that affects the detection accuracy. It also ensures that the positioning rod 105 is firmly connected to the assembly 104 to prevent it from falling off.

[0033] like Figure 1 , Figure 3 and Figure 5 As shown, a return spring 601 is also provided between the assembly 104 and the positioning plate 106, and the return spring 601 is sleeved on the positioning rod 105; a positioning groove is also provided at the bottom end of the assembly 104, and a driven contact wheel 701 passes through the positioning groove. The driven contact wheel 701 passes through the positioning groove of the assembly 104 and directly contacts the road surface. When the road surface is uneven, the driven contact wheel 701 moves up and down with the undulation of the road surface, driving the assembly 104 and the positioning rod 105 to move. The return spring 601 is sleeved on the positioning rod 105, providing downward elastic force, so that the driven contact wheel 701 always keeps in contact with the road surface, ensuring that the distance sensor 5 and the top of the positioning rod 105 are continuously and stably collected.

[0034] The specific usage and function of this embodiment are as follows:

[0035] The drive unit is connected via connecting rod 202, and the moving wheel 203 supports the device's movement. The sweeping component 301 removes debris from the road surface. During inspection, the driven contact wheel 701 contacts the road surface, and the return spring 601 ensures its contact. Road surface undulations cause the positioning rod 105 to move up and down. The distance sensor 5 monitors the change in the distance between the top ends of the positioning rod 105, and the infrared detector 4 simultaneously detects indicators such as cracks. The data is transmitted to the control module 2 for processing and then displayed on the monitor 3, realizing the simultaneous detection of multiple indicators such as flatness and rut depth, providing comprehensive data support for road maintenance.

[0036] The above description is merely an embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
