Description

Technical Field

[0001] The utility model relates to the technical field of road surface detection, in particular to a road surface detection device. Background Art

[0002] Modern roads, whether cement or asphalt, are prone to damage, deformation and other defects after a period of use. Cracks are one of the most common, most likely and earliest damages. They accompany the entire service life of the road and worsen with the age of the road. Cracks on the road surface not only affect the appearance of the road and the comfort of driving, but also easily expand to cause structural damage to the road surface and shorten the service life of the road surface. Therefore, cracks on the road surface should be sealed and repaired in time, otherwise rainwater and other debris will enter the surface structure and roadbed along the cracks, resulting in a decrease in the bearing capacity of the road surface and accelerating local or large-scale damage to the road surface.

[0003] In order to promptly detect and repair road damage or deformation, traditional road maintenance methods often rely on manual inspections and regular testing. However, manual inspections are inefficient and difficult to cover all road sections. In addition, due to factors such as weather, traffic conditions, and the experience level of inspectors, the discovery of road diseases may be delayed. As a result, a variety of road surface detection equipment has appeared on the market, which integrates a variety of sensors and detection equipment and can simultaneously detect multiple parameters of the road surface, such as flatness, cracks, rutting, texture depth, etc. These detection equipment not only make up for the shortcomings of manual inspections, improve the efficiency and accuracy of road maintenance, but also realize real-time data collection and transmission, providing strong support for subsequent maintenance decisions.

[0004] However, traditional detection equipment is insufficient in terms of autonomous mobility and anti-interference capabilities. Traditional detection equipment often relies on manual pushing or traction to move along the road, especially on long-distance or winding roads. The difficulty and labor cost of manually pushing the detection equipment increase significantly. At the same time, during the detection process, if there are uncleaned stones, debris or other foreign objects on the road surface, these obstacles can easily collide or get stuck with the detection equipment, causing damage to the equipment or distortion of the detection results, seriously affecting the accuracy and reliability of the detection, and even causing the detection process to be interrupted, increasing the workload of subsequent data processing and maintenance. Utility Model Content

[0005] The utility model aims to provide a road surface detection device to solve the problem that the traditional detection equipment has insufficient autonomous movement ability and anti-interference ability.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A road surface detection device, comprising: a detection component and a device body, wherein the detection component is detachably installed on the device body, and the detection component is used for detecting the road surface; a moving component, the moving component is installed at the bottom of the device body, and the moving component can drive the device body to move; the moving component includes a first driving component and rollers, the first driving component is connected to the rollers, and the first driving component can drive the rollers to rotate so as to drive the device body to move; a cleaning component, the cleaning component is installed on the device body, and the cleaning component and the detection component are arranged in sequence along the moving direction of the device body.

[0008] According to the above technical means, in the present utility model, a moving component including a first driving component and rollers is installed at the bottom of the device body, so that the device body can move autonomously without manual pushing, reducing the labor burden and improving the detection efficiency. At the same time, in the present utility model, a cleaning component is installed on the device body, and the cleaning component and the detection component are arranged in sequence along the moving direction of the device body, so that before the monitoring component detects the road surface condition, the cleaning component can first clean foreign matters such as stones and debris on the road surface, reducing their interference and potential damage to the detection component, ensuring the cleanliness and normal working state of the detection component, and improving the accuracy and reliability of the detection result.

[0009] Further, the cleaning component includes a second driving component and a cleaning member, the second driving component is installed on the device body, and the second driving component is connected to the cleaning member to drive the cleaning member to rotate and clean the road surface.

[0010] According to the above technical means, the cleaning component drives the cleaning member to rotate through the second driving component to actively clean foreign matters such as stones, debris, and dust on the road surface.

[0011] Further, the cleaning member includes a first rotating shaft and a scraping plate, one end of the scraping plate is fixed on the first rotating shaft, the first rotating shaft is connected to the second driving component, and the second driving component can drive the first rotating shaft to rotate so that the scraping plate rotates and cleans the road surface.

[0012] According to the above technical means, in the present utility model, the scraping plate is used to scrape foreign matters on the road surface physically, such as small stones, soil, and loose asphalt. When the first rotating shaft is driven to rotate by the second driving component, the scraping plate will rotate accordingly and move closely along the road surface, thus achieving an efficient cleaning effect.

[0013] Further, the number of the scraping plates is not less than two, and each of the scraping plates is evenly distributed on the first rotating shaft along the rotation direction of the first rotating shaft.

[0014] According to the above technical means, multiple scraping plates are evenly distributed along the first rotating shaft, so that during each rotation process, multiple scraping plates are in contact with the road surface simultaneously for cleaning, thereby significantly increasing the cleaning area of a single rotation and improving the cleaning efficiency. During the rotation of multiple scraping plates, a certain overlapping area will be formed, which means that some areas may be continuously cleaned by multiple scraping plates. This overlapping cleaning method can further ensure that foreign objects on the road surface are completely removed and improve the cleaning effect.

[0015] Further, the first driving assembly includes a first driving member and a transmission assembly. One end of the transmission assembly is connected to the first driving member, and the other end is connected to the roller.

[0016] According to the above technical means, as an intermediate member connecting the first driving member and the roller, the transmission assembly can ensure that the roller maintains good contact with the road surface, thereby stably pushing the device forward. At the same time, by adjusting the structure or connection method of the transmission assembly, the position of the roller can be flexibly changed to improve the applicability of the road surface detection device.

[0017] Further, the transmission assembly includes a second rotating shaft, a first bevel gear, a second bevel gear, and a third rotating shaft. The first bevel gear and the second bevel gear are meshed with each other. One end of the second rotating shaft is connected to the first driving member, and the other end is connected to the first bevel gear. The first driving member drives the first bevel gear to rotate through the second rotating shaft, so that the second bevel gear rotates; the third rotating shaft is connected to the second bevel gear, and the second bevel gear drives the third rotating shaft to rotate.

[0018] According to the above technical means, the utility model adopts a bevel gear set for transmission to ensure the high efficiency and stability of power transmission during the transmission process. At the same time, the meshing design of the first bevel gear and the second bevel gear effectively transmits the power of the first driving member to the third rotating shaft by changing the transmission direction, so that the roller can be flexibly arranged in different directions and angles when needed to adapt to different road surface conditions or detection requirements.

[0019] Further, the moving assembly includes two rollers, and the two rollers are distributed on both sides of the bottom end of the device body; the third rotating shaft penetrates through the second bevel gear, and both ends of the third rotating shaft are respectively connected to the two rollers.

[0020] According to the above technical means, two rollers are respectively located on both sides of the bottom end of the device body, forming a stable double-wheel support structure, which helps to disperse the weight of the device during movement, reduce the situation of single-point force, and thus improve the stability and balance of the device. Since the third rotating shaft passes through the second bevel gear and is directly connected to the two rollers, the power can be evenly transmitted to the two rollers, ensuring that they are evenly stressed when rotating synchronously, and further enhancing the stability of the road surface detection device.

[0021] Furthermore, the detection component includes a detector and a first clamping member, and the first clamping member is connected to the detector; a second clamping member is formed on the device body, and the first clamping member is adapted to the second clamping member. The first clamping member can be clamped or unclamped with the second clamping member, so that the detector can be detachably installed on the device body.

[0022] According to the above technical means, through the matching design of the first clamping member and the second clamping member, the detector can be conveniently and quickly installed on the device body or removed from the device body, so that when the detector needs to be replaced, repaired or upgraded, there is no need to disassemble the entire device, greatly improving the work efficiency.

[0023] Since the detector is detachable, different types of detectors can be replaced according to different detection requirements, thereby expanding the applicability of the road surface detection device.

[0024] Furthermore, the first clamping member is a clamping block, and the second clamping member is a clamping groove.

[0025] According to the above technical means, the design of the clamping block and the clamping groove makes the installation and disassembly of the detector simple and fast. The user only needs to align the clamping block with the clamping groove and gently push it in to complete the installation; similarly, when disassembling, only need to gently pull out the clamping block, greatly reducing the operation difficulty and cost.

[0026] Furthermore, the detection component further includes a connecting rod. One end of the connecting rod is connected to the detector, and the other end is connected to the first clamping member, and the connecting rod is vertically arranged; a through hole is formed at the bottom of the device body, and one end of the connecting rod passes through the through hole, so that the detector is erected at the bottom of the device body.

[0027] According to the above technical means, the connecting rod is vertically arranged, providing a stable support for the detector. By adjusting the length and angle of the connecting rod, the position of the detector at the bottom of the device body can be precisely controlled to ensure that it is aligned with the area to be detected.

[0028] The beneficial effects achieved by the present utility model:

[0029] The utility model installs a moving component at the bottom of the device body, including a first driving component and rollers, enabling the device body to move autonomously without manual pushing, reducing the labor burden and improving the detection efficiency.

[0045] The following will introduce and describe in detail the technical solutions of this embodiment in conjunction with specific drawings.

[0046] As Figure 1 shown, this embodiment provides a road surface detection device, including: a detection component 1 and a device body 2. The detection component 1 is detachably installed on the device body 2, and the detection component 1 is used to detect the road surface; a moving component 3, the moving component 3 is installed at the bottom of the device body 2, and the moving component 3 can drive the device body 2 to move; the moving component 3 includes a first driving component 31 and rollers 32, the first driving component 31 is connected to the rollers 32, and the first driving component 31 can drive the rollers 32 to rotate to drive the device body 2 to move; a cleaning component 4, the cleaning component 4 is installed on the device body 2, and the cleaning component 4 and the detection component 1 are arranged in sequence along the moving direction of the device body 2.

[0047] The utility model installs a moving component 3 at the bottom of the device body 2, including a first driving component 31 and rollers 32, enabling the device body 2 to move autonomously without manual pushing, reducing the labor burden and improving the detection efficiency. At the same time, the utility model installs a cleaning component 4 on the device body 2, and the cleaning component 4 and the detection component 1 are arranged in sequence along the moving direction of the device body 2, so that before the monitoring component detects the road surface condition, the cleaning component 4 can clean foreign matters such as stones and debris on the road surface in advance, reduce their interference and potential damage to the detection component 1, ensure the cleanliness and normal working state of the detection component 1, and improve the accuracy and reliability of the detection results.

[0048] As Figure 2 shown, the cleaning component 4 includes a second driving component 4131 and a cleaning member 42. The second driving component 4131 is installed on the device body 2, and the second driving component 4131 is connected to the cleaning member 42 to drive the cleaning member 42 to rotate and clean the road surface. The cleaning member 42 includes a first rotating shaft 421 and a scraping plate 422. One end of the scraping plate 422 is fixed on the first rotating shaft 421, and the first rotating shaft 421 is connected to the second driving component 4131. The second driving component 4131 can drive the first rotating shaft 421 to rotate, so that the scraping plate 422 rotates and cleans the road surface.

[0049] The cleaning component 4 drives the cleaning member 42 to rotate through the second driving component 4131 to actively clean foreign matters such as stones, debris, and dust on the road surface. In this embodiment, the scraping plate 422 scrapes off foreign matters on the road surface through a physical method, such as small stones, soil, and loose asphalt. When the first rotating shaft 421 is driven to rotate by the second driving component 4131, the scraping plate 422 will rotate accordingly and move closely along the road surface, thereby achieving an efficient cleaning effect.

[0050] In other embodiments, the shape, material, hardness, and other characteristics of the cleaning member 42 need to be optimized according to the road surface conditions and detection requirements. For example, for different types of road surface foreign matters, cleaning brushes or scraping blades with different shapes and hardnesses can be used; in order to improve the cleaning effect, auxiliary devices such as a water spraying device or a dust suction device can also be set on the cleaning member 42.

[0051] In this embodiment, the number of scraping plates 422 is not less than two, and the scraping plates 422 are evenly distributed on the first rotating shaft 421 along the rotation direction of the first rotating shaft 421. The multiple scraping plates 422 are evenly distributed along the first rotating shaft 421, so that during each rotation process, multiple scraping plates 422 are in contact with the road surface simultaneously for cleaning, and thus the cleaning area of a single rotation is significantly increased, thereby improving the cleaning efficiency. During the rotation of the multiple scraping plates 422, a certain overlapping area will be formed, which means that some areas may be continuously cleaned by multiple scraping plates 422. This way of overlapping cleaning can further ensure that foreign matters on the road surface are completely removed and improve the cleaning effect.

[0052] As Figure 3 shown, in this embodiment, the first driving assembly 31 includes a first driving member 311 and a transmission assembly 312. One end of the transmission assembly 312 is connected to the first driving member 311, and the other end is connected to the roller 32. As an intermediate member connecting the first driving member 311 and the roller 32, the transmission assembly 312 can ensure that the roller 32 maintains good contact with the road surface, so as to stably push the device forward. At the same time, by adjusting the structure or connection method of the transmission assembly 312, the position of the roller 32 can be flexibly changed to improve the applicability of the road surface detection device.

[0053] In other embodiments, different materials and specifications of the roller 32 can be selected according to different road surface conditions. For example, when the road surface is not very stable and regular, the roller 32 can be made of more wear-resistant materials, or the shape of the roller 32 can be adjusted to adapt to different road conditions.

[0054] As Figure 3 shown, the transmission assembly 312 in this embodiment includes a second rotating shaft 3121, a first bevel gear 3122, a first bevel gear 312, and a third rotating shaft 3124. The first bevel gear 3122 meshes with the first bevel gear 312. One end of the second rotating shaft 3121 is connected to the first driving member 311, and the other end is connected to the first bevel gear 3122. The first driving member 311 drives the first bevel gear 3122 to rotate through the second rotating shaft 3121, so as to make the first bevel gear 312 rotate; the third rotating shaft 3124 is connected to the first bevel gear 312, and the first bevel gear 312 drives the third rotating shaft 3124 to rotate. In this embodiment, a bevel gear set is used for transmission to ensure the high efficiency and stability of power transmission during the transmission process. At the same time, the meshing design of the first bevel gear 3122 and the first bevel gear 312 effectively transmits the power of the first driving member 311 to the third rotating shaft 3124 by changing the transmission direction, so that the roller 32 can be flexibly arranged in different directions and angles when needed to adapt to different road surface conditions or detection requirements.

[0055] In this embodiment, the moving component 3 includes two rollers 32, which are distributed on both sides of the bottom end of the device body 2; the third rotating shaft 3124 penetrates through the first bevel gear 312, and both ends of the third rotating shaft 3124 are respectively connected to the two rollers 32. The two rollers 32 are respectively located on both sides of the bottom end of the device body 2, forming a stable double-wheel support structure, which helps to disperse the weight of the device during movement, reduce the situation of single-point force, and thus improve the stability and balance of the device. Since the third rotating shaft 3124 penetrates through the first bevel gear 312 and is directly connected to the two rollers 32, the power can be evenly transmitted to the two rollers 32, ensuring that they are evenly stressed when rotating synchronously, and further enhancing the stability of the road surface detection device.

[0056] As Figure 4 and Figure 5 shown, in this embodiment, the detection component 1 includes a detector 11 and a first clamping member 12, and the first clamping member 12 is connected to the detector 11; a second clamping member 21 is formed on the device body 2, and the first clamping member 12 is adapted to the second clamping member 21. The first clamping member 12 can be clamped or unclamped with the second clamping member 21, so that the detector 11 can be detachably installed on the device body 2. Through the matching design of the first clamping member 12 and the second clamping member 21, the detector 11 can be conveniently and quickly installed on the device body 2 or detached from the device body 2, so that when the detector 11 needs to be replaced, repaired or upgraded, there is no need to disassemble the whole device, which greatly improves the work efficiency. Since the detector 11 is detachable, different types of detectors 11 can be replaced according to different detection requirements, thereby expanding the applicability of the road surface detection device.

[0057] In this embodiment, the first clamping member 12 is a clamping block, and the second clamping member 21 is a clamping groove. The design of the clamping block and the clamping groove makes the installation and disassembly of the detector 11 simple and fast. The user only needs to align the clamping block with the clamping groove and gently push it in to complete the installation; similarly, when disassembling, only need to gently pull out the clamping block, which greatly reduces the operation difficulty and cost.

[0058] In other embodiments, when the road surface state is relatively unstable and the undulation is relatively large, the first clamping member 12 is a threaded hole or a nut, and the second clamping member 21 is a threaded rod. The cooperation between the threaded rod and the threaded hole or the nut makes the connection between the detection component 1 and the device body 2 more stable, and better performs the road surface detection task.

[0059] As Figure 4 and Figure 5As shown in the figure, in this embodiment, the detection component 1 further includes a connecting rod 13. One end of the connecting rod 13 is connected to the detector 11, and the other end is connected to the first clamping member 12, and the connecting rod 13 is vertically arranged. A through hole 22 is formed at the bottom of the device body 2. One end of the connecting rod 13 passes through the through hole 22 so that the detector 11 is mounted on the bottom of the device body 2. The vertical arrangement of the connecting rod 13 provides a stable support for the detector 11. By adjusting the length and angle of the connecting rod 13, the position of the detector 11 at the bottom of the device body 2 can be accurately controlled to ensure that it is aligned with the area to be detected.

[0060] The serial numbers of the embodiments of the present application above are only for description and do not represent the superiority or inferiority of the embodiments. The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
