Description

Technical Field

[0001] The invention relates to the technical field of pavement crack detection, and in particular to a pavement crack detection and repairing device. Background Art

[0002] Pavement cracks are the initial manifestation of pavement damage. If they are not discovered and treated in time, they will gradually expand and even cause more serious pavement damage. This will not only endanger driving safety, but may also lead to traffic accidents. Therefore, through regular and professional inspections, pavement cracks can be discovered in time, providing strong support for subsequent maintenance work.

[0003] However, the existing pavement crack detection and repair equipment still has the following problems in actual use:

[0004] 1. When the existing detection devices are conducting road surface detection, in the complex and changeable road environment, the traditional road surface crack detection devices are often interfered by factors such as light, shadow, and oil pollution. The changes in light and shadow will affect the detection device's ability to identify road surface cracks, making the cracks blurred or difficult to distinguish in the image. Debris on the road surface, such as leaves, gravel, etc., may also block the cracks, making it impossible for the detection device to accurately capture the crack information, which may not only lead to unnecessary detection or repair operations, but also cause a waste of resources such as repair agents.

[0005] 2. In addition, in the process of pavement crack detection, most of the existing detection equipment relies on visual sensing devices to accurately measure the width and depth of cracks. Especially on bumpy and uneven roads, the vibration of vehicles or detection equipment often has an adverse effect on visual sensors. When visual sensors are disturbed by vibration, their stability and accuracy will be greatly reduced, and this vibration may cause the image captured by the sensor to be blurred, distorted, or even completely fail, and the crack features that should have been clearly visible will become difficult to identify, thereby affecting the judgment of the accuracy of pavement crack detection.

[0018] Compared with the prior art, the pavement crack detection and repair device provided by the present invention has the following beneficial effects:

[0019] 1. Compared with the traditional device, the road crack detection device of the present invention can conveniently adjust the overall detection height by adjusting the operation of the electric cylinder under the setting of the telescopic shaft and the buffer spring in the adjustable cleaning mechanism. This function is particularly important in a complex and changeable road environment, because it can ensure that the detection device always maintains an appropriate distance from the road surface, thereby improving the accuracy of detection. In addition, the buffer spring with elastic buffering in the present invention plays a role in reducing overall vibration. On uneven or bumpy roads, this buffering effect can significantly reduce the vibration interference of the visual integrated control device, thereby avoiding adverse effects on the accuracy of crack detection;

[0020] The function of collecting impurities and dust by the cleaning block in the present invention can effectively reduce the interference of road impurities and dust on crack detection, ensure that the detection device can accurately capture crack information, and further improve the accuracy of detection. The present invention has significantly improved the detection accuracy compared with traditional devices by adjusting the detection height, reducing vibration interference, and cleaning impurities and dust.

[0021] 2. By setting the spherical connecting shaft and the collision ball, the telescopic probe rod detects the cracks, and the contraction of the telescopic probe rod drives the reset spring to press the first pressure sensor. The first pressure sensor can quickly send an electrical signal to the visual integrated control device, and the visual integrated control device can analyze and determine the crack depth measurement. When the bottom of the telescopic probe rod collides in the crack, the telescopic probe rod drives the spherical connecting shaft, and the spherical connecting shaft drives the collision ball to collide with the surface of the arc push plate. The arc push plate collision enables the second pressure sensor to quickly collect the extrusion force and send it to the visual integrated control device for analysis, and then the visual integrated control device can quickly measure the depth and width of the crack. The setting of the present invention can be used in conjunction with the visual integrated control device for synchronous comparison and determination. Compared with the traditional single measurement by visual sensor, the setting of the present invention can be used to more accurately analyze data and realize accurate data collection. After comparison by the visual integrated control device, the filling of the repair agent by the repair grouting device can be controlled to reduce unnecessary waste of the repair agent.

[0022] 3. Through the setting of adjustable cleaning mechanism and measuring and detecting mechanism, when the detecting equipment is in the non-detection stage, the electric cylinder can be directly adjusted to extend and retract, and the telescopic shaft can be pushed to rotate at the bottom of the machine body through the auxiliary connecting plate, so that the whole machine body can be lifted. Moreover, when the detection environment changes, the height of the whole machine body can be controlled to enable the measuring and detecting mechanism to detect cracks more accurately.

[0023] 4. When the existing repair agent is applied on the surface of the crack, it may not be able to penetrate into the crack due to its certain viscosity. The present invention can drive the bump to collide with the surface of the skateboard through the operation of the motor through the bump setting. When the collision occurs, the elastic element will be compressed and release energy. Since the skateboard slides on the pull rod, the elastic action of the vibration spring can drive the vibration pressure plate to vibrate and hit the surface of the repair agent, so that the repair agent can better penetrate into the gap. The effect of this vibration and hitting can break the sticky barrier on the surface of the repair agent, making it easier to penetrate into the crack. In this way, the repair agent can better contact and bond with the inner wall of the crack, thereby improving the repair effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The measuring and detecting mechanism 3 is used to detect the width and depth of road cracks;

[0049] The measuring and detecting mechanism 3 comprises a telescopic probe rod 31, a reset spring 32 is sleeved on the outer surface of the telescopic probe rod 31, a first pressure sensor 33 is fixedly connected to the upper end of the telescopic probe rod 31, one end of the reset spring 32 is fixedly connected to the telescopic probe rod 31, and the other end of the reset spring 32 is fixedly connected to the first pressure sensor 33, a spherical connecting shaft 34 is fixedly connected to the upper end of the first pressure sensor 33, an arc-shaped protective cover 39 is slidably connected to the bottom of the middle part of the body 1, and the outer surface of the spherical connecting shaft 34 is slidably connected to the inner wall of the arc-shaped protective cover 39;

[0050] A collision ball 35 is fixedly connected to the side of the spherical connecting shaft 34 away from the first pressure sensor 33, and a curved push plate 36 is arranged on the outer surface of the side of the collision ball 35 away from the spherical connecting shaft 34.

The end of the auxiliary spring 37 away from the curved push plate 36 is fixedly connected to the second pressure sensor 38, and the second pressure sensor 38 is circumferentially installed in the curved protective cover 39;

[0051] A pouring repair mechanism 4 is also provided on one side of the measuring and detecting mechanism 3. The pouring repair mechanism 4 is used to repair cracks. The pouring repair mechanism 4 includes a first elastic telescopic baffle 41. The first elastic telescopic baffle 41 is fixedly connected to the bottom of the repair grouting device 12. A high-pressure grouting pipe 43 is connected to the repair grouting device 12. A baffle 42 is provided at one end of the high-pressure grouting pipe 43 away from the repair grouting device 12. The baffle 42 is fixedly connected to the repair grouting device 12.

[0052] The pouring repair mechanism 4 also includes a fixing plate 44, the surface of the fixing plate 44 is fixedly connected to the repair grouting device 12, a pull rod 46 is evenly fixedly connected to the lower surface of the fixing plate 44, a slide plate 49 is slidably connected to the outer surface of the pull rod 46, and a vibration spring 48 is sleeved on the pull rod 46 near the lower side of the slide plate 49, one end of the vibration spring 48 is fixedly connected to the bottom of the slide plate 49, and the other end of the vibration spring 48 is fixedly connected to a vibration pressure plate 47;

[0053] One end of the pull rod 46 away from the fixed plate 44 is fixedly connected to the vibrating pressure plate 47, a protrusion 45 is provided on the upper surface of the slide plate 49, a motor is installed on the bottom of the repair grouting device 12 near the protrusion 45, and the middle of the protrusion 45 is fixedly connected to the motor drive shaft;

[0054] Among them: the repair grouting device 12 is equipped with a grouting machine near the bottom of the machine body 1, wherein the visual integrated control device 13 is electrically connected to the grouting machine, and there is an electrical connection relationship between the second pressure sensor 38 and the visual integrated control device 13, and the electrical signal is transmitted to the visual integrated control device 13 through the second pressure sensor 38. Through the algorithm analysis between the visual integrated control device 13, the start-up operation time of the grouting machine can be controlled, and the accuracy of the material discharge amount can be controlled through the operation time of the grouting machine.

[0055] In the prior art, most of the existing detection equipment relies on visual sensing devices to accurately measure the width and depth of cracks. Especially on bumpy and uneven roads, the vibration of vehicles or detection equipment often has an adverse effect on visual sensors. Compared with the prior art, through the implementation of this embodiment, the depth and width of the cracks can be quickly measured through the visual integrated control device 13. The setting of the present invention can be used in conjunction with the visual integrated control device 13 for synchronous comparison and determination. Compared with the traditional single measurement through visual sensors, the setting of the present invention can be more accurate in data analysis and realize accurate data collection. After comparison by the visual integrated control device 13, the filling of the repair agent by the repair grouting device 12 can be controlled to reduce unnecessary waste of the repair agent.

[0056] Everything in the above example works like this:

[0057] In the initial state: the electric cylinder is not started, the dust suction device 11 is not started, the repair grouting device 12 is not started, and the visual integrated control device 13 is not started.

[0058] The following is the working process of the adjustable cleaning mechanism 2 for cleaning impurities and dust on the cracks of the road surface:

[0059] When in use, the operator first starts the electric cylinder, which can push the auxiliary connecting plate 22. The movement of the auxiliary connecting plate 22 can drive the telescopic shaft 21 to rotate at the bottom of the machine body 1. At this time, the operator starts the cylinder, and the road cracks are made to fit with the bottom of the cleaning block 28 under the control of the extension and contraction of the cylinder. At this time, by pushing the machine body 1 to move, there is a certain friction between the gripping wheel 24 and the ground, and the gripping wheel 24 starts to rotate through friction. The gripping wheel 24 is connected to the end of the telescopic shaft 21 away from the auxiliary connecting plate 22, and the middle of the gripping wheel 24 is fixedly connected to the middle of the turntable 25.

[0060] Further, the rotation of the gripping wheel 24 will drive the rotating disk 25 to start rotating in the same direction. Figure 4 As shown, since the extrusion column at the eccentric position of the rotating disk 25 away from the gripping wheel 24 is slidably connected to the auxiliary groove 27 provided in the swing plate 26, and since the bottom of the swing plate 26 is rotatably connected to the bottom end of the telescopic shaft 21, the rotation of the rotating disk 25 will drive the swing plate 26 to start reciprocating rotation on the telescopic shaft 21. At this time, since the swing plate 26 is fixedly connected to the bottom end of the swing plate 26, the swinging of the swing plate 26 will drive the cleaning block 28 to start synchronous swinging. At this time, since the bottom end of the cleaning block 28 is made of flexible anti-corrosion material and has a certain wear-resistant function, when the bottom of the cleaning block 28 is in contact with the ground, the dust and impurities on the surface of the crack will be cleaned by the swinging of the cleaning block 28;

[0061] Furthermore, when cleaning impurities, the dust collecting device 11 is started, and the impurities are directly sucked into the dust collecting device 11 through the feed hole of the impurity baffle 29 for collection. Compared with the traditional device, the pavement crack detection device of the present invention can adjust the overall detection height conveniently by adjusting the operation of the electric cylinder under the setting of the telescopic shaft 21 and the buffer spring 23 in the adjustable cleaning mechanism 2. This function is particularly important in a complex and changeable road environment, because it can ensure that the detection device always maintains an appropriate distance from the road surface, thereby improving the accuracy of the detection. In addition, the buffer spring 23 with elastic buffering in the present invention plays a role in reducing the overall vibration. On an uneven or bumpy road surface, this buffering effect can significantly reduce the vibration interference of the visual integrated control device 13, thereby avoiding adverse effects on the accuracy of crack detection.

[0062] In the present invention, the function of collecting impurities and dust by the cleaning block 28 can effectively reduce the interference of road impurities and dust on crack detection, ensure that the detection device can accurately capture crack information, and further improve the accuracy of detection. The present invention has significantly improved the detection accuracy compared with traditional devices by adjusting the detection height, reducing vibration interference, and cleaning impurities and dust.

[0063] Please refer to the above working process Figures 1 to 8 .

[0064] The following is the working process of the measuring and detecting mechanism 3 for detecting the width and depth of road cracks and the pouring and repairing mechanism 4 for repairing the cracks:

[0065] As shown above, when the machine body 1 is moved as a whole over the crack for measurement, the visual integrated control device 13 is used to measure the ground. The electric push rod can control the arc-shaped protective cover 39 slidably connected to the bottom of the machine body 1 to locate the crack position through the position detection of the visual integrated control device 13. Figure 5 As shown, at this time, the telescopic probe 31 located on the crack can be quickly extended into the crack under the position control of the arc-shaped protective cover 39. At this time, the pressure sensing between the first pressure sensor 33 and the reset spring 32 can be fed back to the visual integrated control device 13 through an electrical signal for recording and collection. At this time, when the body 1 moves, the telescopic probe 31 will be driven to move in the crack, and the collision between the crack and the bottom end of the telescopic probe 31 can drive the spherical connecting shaft 34 to start rotating in the arc-shaped protective cover 39. At this time, the rotation of the spherical connecting shaft 34 in the arc-shaped protective cover 39 will drive the collision ball 35 to squeeze the surface of the arc-shaped push plate 36, and by squeezing the arc-shaped push plate 36, this At the same time, since the arc push plate 36 is connected to the second pressure sensor 38 through the auxiliary spring 37, the electric signal of the pressing of the auxiliary spring 37 is collected by the second pressure sensor 38, and sent to the visual integrated control device 13 through the electric signal. The visual integrated control device 13 can accept and convert the visual collection of cracks through the visual integrated control device 13 and compare the mechanical collection signal of the telescopic probe 31. After the conversion of the electric signal, the internal controller controls the repair grouting device 12 electrically connected to the visual integrated control device 13 to start. The quantitative control of the repair grouting device 12 by the controller enables the repair grouting device 12 to accurately fill and repair the cracks.

[0066] When the telescopic probe 31 performs mechanical sampling of the crack, the pressing of the telescopic probe 31 on the crack depth will collect electrical signals through the first pressure sensor 33, and these signals will then be sent to the core analysis visual integrated control device 13, and the visual integrated control device 13 is not only responsible for receiving these signals, but also for conversion and processing. It will compare and analyze the visual acquisition information of the crack, which is usually obtained through a camera or other visual sensors, with the mechanical acquisition signals. This comparative analysis can more accurately determine the actual condition of the crack, including its position, size and shape, etc. Once the analysis is completed, the visual integrated control device 13 will send the processed electrical signal to the internal controller, which is electrically connected to the repair grouting device 12. According to the analysis data provided by the visual integrated control device 13, the controller will accurately control the start-up and filling amount of the repair grouting device 12;

[0067] This quantitative control mechanism ensures that the repair agent can be accurately filled into the cracks, without excessive waste and without affecting the repair effect due to insufficient filling. In this way, the entire system can achieve efficient and accurate road crack repair, greatly improving the quality and efficiency of the repair work.

[0068] Further, if Figure 7 As shown, when the repair agent is sprayed on the crack surface under the high pressure grouting pipe 43, the arc surface of the baffle 42 can prevent the repair agent from splashing when sprayed at a certain pressure, and Figure 8 As shown, after the motor is started, the protrusion 45 is driven to rotate. Since the protrusion 45 is provided with an arc surface, when the protrusion 45 rotates, it can collide with the surface of the slide plate 49. When the collision occurs, the elastic element will be compressed and release energy. Since the slide plate 49 slides on the pull rod 46, the elastic action of the vibration spring 48 can drive the vibration pressure plate 47 to vibrate and strike the surface of the repair agent, so that the repair agent can better penetrate into the gap. The effect of this vibration and striking can break the sticky barrier on the surface of the repair agent, making it easier to penetrate into the crack. In this way, the repair agent can better contact and bond with the inner wall of the crack, thereby improving the repair effect.
