[0002] Highway pavement smoothness refers to the vertical deviation of the pavement surface from the ideal plane. Pavement smoothness is an important indicator in pavement evaluation and pavement construction acceptance, and mainly reflects the smoothness of the pavement longitudinal section profile curve.

[0003] Currently, highway pavement smoothness testing mostly relies on rolling a detection wheel along the road surface. When the detection wheel rolls over a raised or sunken road surface, it will adaptively move up and down. The displacement of the detection wheel is measured by a measuring instrument to determine whether the road surface smoothness meets the requirements. However, there are often debris such as sand and gravel on the road surface. When the detection wheel acts on the sand and gravel, it will also move under the influence of the sand and gravel. In this case, the accuracy of the detection result is difficult to guarantee. Summary of the Invention

At this time, the alarm component sends an alarm signal to remind the staff that there is a flatness defect in the road surface at the current position of the detection roller. When the detection roller rolls to a concave road surface, the detection roller moves downward compared to the walking bracket, and the elastic support component adaptively extends. At this time, the alarm component also sends an alarm signal to remind the staff that there is a flatness defect in the road surface at the current position of the detection roller.

[0044] See also Figure 1 as well as Figure 2 The present embodiment provides a mobile highway engineering quality inspection device, including a walking bracket 10, an inspection roller 20, a cleaning component 30, a driving component 40, an elastic support component 50 and an alarm component 60. The bottom edge of the walking bracket 10 is installed with a walking wheel 101, the inspection roller 20 is arranged below the walking bracket 10, and the elastic support component 50 is installed on the bottom wall of the walking bracket 10, for providing elastic support for the inspection roller 20, so that the inspection roller 20 can move up and down when rolling to the raised and recessed positions of the road surface. The alarm component 60 is installed on the side wall of the walking bracket 10. When the detection roller 20 moves up and down, the alarm component 60 sends an alarm signal. The cleaning component 30 is arranged in front of the detection roller 20, and the driving component 40 is installed on the side of the detection roller 20. When the detection roller 20 rolls along the road surface, the driving component 40 is used to drive the cleaning component 30 to move back and forth in front of the detection roller 20 along a rolling direction perpendicular to the detection roller 20 to clean the sand and gravel on the road surface in front of the detection roller 20.

[0045] When it is necessary to detect the flatness of the road surface, the walking bracket 10 can be driven to walk along the road surface, and the walking wheel 101 and the detection roller 20 can roll adaptively along the road surface. When the detection roller 20 rolls to a raised road surface, the detection roller 20 moves upward compared to the walking bracket 10, thereby driving the elastic support component 50 to compress. At this time, the alarm component 60 sends an alarm signal to remind the staff that there is a flatness defect on the road surface at the current position of the detection roller 20. When the detection roller 20 rolls to a concave road surface, the detection roller 20 moves downward compared to the walking bracket 10, and the elastic support component 50 extends adaptively. At this time, the alarm component 60 also sends an alarm signal. The cleaning component 30 is driven by the driving component 40 to move back and forth in front of the detection roller 20 along the rolling direction perpendicular to the detection roller 20, thereby cleaning the sand and gravel on the road surface in front of the detection roller 20, thereby avoiding the presence of sand and gravel that affects the up and down movement of the detection roller 20, thereby improving the accuracy of the road surface flatness detection result.

[0046] See also Figure 4 as well as Figure 6 In one embodiment, the elastic support assembly 50 includes a positioning rod 501, a second elastic member 502 and a U-shaped bracket plate 503, the upper end of the positioning rod 501 is fixedly connected to the bottom wall of the walking bracket 10, and the lower end passes through the U-shaped bracket plate 503 and movably cooperates with the U-shaped bracket plate 503, the positioning rod 501 is vertically distributed, one end of the second elastic member 502 is connected to the bottom wall of the walking bracket 10, and the other end is connected to the U-shaped bracket plate 503, for providing elastic support for the U-shaped bracket plate 503, the detection roller 20 is arranged on the inner side of the U-shaped bracket plate 503, and a rotating shaft 201 is fixedly provided on the side wall of the detection roller 20, and the end of the rotating shaft 201 away from the detection roller 20 is rotatably connected to the side wall of the U-shaped bracket plate 503.

[0047] When the walking bracket 10 walks along the road surface, the walking wheel 101 and the detection roller 20 roll along the road surface, and the detection roller 20 drives the rotating shaft 201 to rotate compared to the U-shaped bracket plate 503. When the detection roller 20 rolls to the raised road surface, the raised road surface drives the detection roller 20 to move up, and the detection roller 20 drives the U-shaped bracket plate 503 to move up compared to the positioning rod 501 through the rotating shaft 201. At this time, the second elastic member 502 is compressed by force; when the detection roller 20 rolls to the recessed road surface, the second elastic member 502 pushes the U-shaped bracket plate 503 so that the U-shaped bracket plate 503 moves downward compared to the positioning rod 501, and then drives the detection roller 20 to move downward synchronously through the rotating shaft 201.

[0048] See also Figure 6 In one embodiment, a limit block 504 is fixedly provided at the lower end of the positioning rod 501. By setting the limit block 504, the U-shaped bracket plate 503 can be limited outside the positioning rod 501, thereby preventing the U-shaped bracket plate 503 from detaching from the lower end of the positioning rod 501.

[0049] See also Figure 6 as well as Figure 7 In one embodiment, the alarm component 60 includes a support rod 601, a first conductive block 602, a second conductive block 603, a third conductive block 604, a fourth conductive block 605 and a buzzer 607. The support rod 601 is fixedly arranged on the bottom wall of the walking bracket 10, and the support rod 601 vertically penetrates the U-shaped bracket plate 503 and movably cooperates with the U-shaped bracket plate 503. The first conductive block 602 is fixedly arranged on the rod body of the support rod 601 above the U-shaped bracket plate 503. The fourth conductive block 60 5 is fixedly mounted on the rod body of the support rod 601 located inside the U-shaped bracket plate 603, the second conductive block 603 is fixedly mounted on the upper portion of the U-shaped bracket plate 503, and the third conductive block 604 is fixedly mounted on the inner top wall of the U-shaped bracket plate 503. Wires (not shown in the figure) are connected between the first conductive block 602 and the fourth conductive block 605 and the buzzer 607, and the second conductive block 603 and the third conductive block 604 are connected to an external power supply (not shown in the figure) through wires (not shown in the figure).

[0050] When the detection roller 20 rolls to the raised road surface and drives the U-shaped bracket plate 503 to move upward compared to the positioning rod 501, the U-shaped bracket plate 503 drives the second conductive block 603 to move upward, and the second conductive block 603 contacts the first conductive block 602. At this time, the external power supply supplies power to the buzzer 607 through the second conductive block 603, the first conductive block 602 and the corresponding wires, thereby driving the buzzer 607 to emit a sound to remind the staff that there is a flatness defect on the road surface where the detection roller 20 is located; when the detection roller 20 rolls to the recessed road surface and drives the U-shaped bracket plate 503 to move downward compared to the positioning rod 501, the U-shaped bracket plate 503 drives the third conductive block 604 to move downward, and the third conductive block 604 contacts the fourth conductive block 605. At this time, the external power supply supplies power to the buzzer 607 through the third conductive block 604, the fourth conductive block 605 and the corresponding wires, thereby driving the buzzer 607 to emit a sound to remind the staff that there is a flatness defect on the road surface where the detection roller 20 is located.

[0051] See also Figure 3 、 Figure 4 as well as Figure 5In one embodiment, the cleaning component 30 includes a support plate 301 and a flexible pusher 302. The support plate 301 is arranged in front of the detection roller 20. The flexible pusher 302 is provided with two groups. The two groups of flexible pushers 302 are respectively arranged on the opposite sides of the bottom of the support plate 301. An ear plate 306 is fixedly provided on the side wall of the support plate 301. The driving component 40 includes an arc-shaped protrusion 401, a sliding sleeve 402, a connecting rod 403 and a first elastic member 404. The arc-shaped protrusion 401 is provided There are several groups, several of the arc-shaped protrusions 401 are fixedly arranged on the side wall of the detection roller 20, and several of the arc-shaped protrusions 401 are distributed in a ring-shaped interval on the side wall of the detection roller 20. The sleeve 402 is movably sleeved on the outside of the rotating shaft 201. One end of the first elastic member 404 is connected to the inner wall of the U-shaped bracket plate 503, and the other end is connected to the sleeve 402, which is used to provide elastic support for the sleeve 402. One end of the connecting rod 403 is connected to the sleeve 402, and the other end is connected to the ear plate 306.

[0052] When the walking bracket 10 walks along the road surface so that the walking wheel 101 and the detection roller 20 roll along the road surface, the detection roller 20 can push the support plate 301 to move synchronously through the rotating shaft 201, the sliding sleeve 402 and the connecting rod 403. At this time, the two sets of flexible pushing members 302 at the bottom of the support plate 301 are in contact with the road surface and move synchronously. When the detection roller 20 rolls along the road surface, the detection roller 20 drives the plurality of arc-shaped protrusions 401 to rotate. When the plurality of arc-shaped protrusions 401 rotate, they act on the connecting rod 403 in turn. When a certain set of arc-shaped protrusions 402 acts on the connecting rod 403, it can push the connecting rod 403 so that the connecting rod 403 is away from the detection roller 20. At this time, the connecting rod 403 drives the support plate 301 and the two sets of flexible pushers 302 to move along the rolling direction perpendicular to the detection roller 20. One set of flexible pushers 302 pushes the sand and gravel debris on the road surface in front of the detection roller 20 to the side of the detection roller 20. On the other hand, the connecting rod 403 drives the sliding sleeve 402 to slide along the outside of the rotating shaft 201, so that the first elastic member 302 is pushed away from the detection roller 20. When the first elastic member 404 is compressed and the group of arc-shaped protrusions 401 separates from the connecting rod 403, the first elastic member 404 pushes the sliding sleeve 402 so that the sliding sleeve 402 slides along the outer direction of the rotating shaft 201, thereby driving the connecting rod 403 close to the detection roller 20. When the connecting rod 403 approaches the detection roller 20, it drives the support plate 301 and the two groups of flexible pushing members 302 to move in the opposite direction perpendicular to the rolling direction of the detection roller 20. The other group of flexible pushing members 302 pushes the sand and gravel on the road surface in front of the detection roller 20 toward the detection roller 20. The other side of the detection roller 20 is positioned so that when the detection roller 20 rolls along the road surface, the connecting rod 403 is acted on in sequence by a number of arc-shaped protrusions 401, so that the support plate 301 and the two sets of flexible pushing members 302 move in an S-shaped trajectory on the road surface in front of the detection roller 20, and then the sand and gravel on the road surface in front of the detection roller 20 are continuously pushed to the side of the detection roller 20, thereby preventing the detection roller 20 from encountering sand and gravel when rolling along the road surface, thereby affecting the accuracy of the road surface flatness detection result.

[0053] In one embodiment, the first elastic member 404 and the second elastic member 502 can be springs or metal springs, which are not limited here.

[0054] See also Figure 3 In one embodiment, an arc-shaped baffle 303 is fixedly provided at one end of the bottom of the support plate 301 away from the detection roller 20. When the support plate 301 moves along the road surface with the detection roller 20, the arc-shaped baffle 303 can block sand and gravel on the road surface to prevent sand and gravel from entering between the two sets of flexible pushing members 302, resulting in the sand and gravel being unable to be smoothly pushed to the side of the detection roller 20.

[0055] In one embodiment, the flexible pushing member 302 may be a rubber scraper or a metal scraper, which is not limited here.

[0056] See also Figure 3 In one embodiment, a support column 304 is fixedly provided at the bottom of the support plate 301, and a ball 305 is movably embedded at the bottom of the support main rod 304.

[0057] When the walking bracket 10 moves along the road surface, the ball 305 acts on the road surface and rolls along the road surface, and the ball 305 provides rolling support to the support plate 301, so that when the detection roller 20 rolls and then pushes the support plate 301 through a number of arc-shaped protrusions 401, the support plate 301 can move flexibly, so that the flexible pushing member 302 can smoothly push away the sand and gravel debris on the road surface in front of the detection roller 20.

[0058] See also Figure 1 as well as Figure 2 In one embodiment, the detection roller 20 and the elastic support assembly 50 are provided in a one-to-one correspondence under the walking bracket 10. Several detection rollers 20 are spaced apart along the length direction of the walking bracket 10. A group of cleaning assemblies 30 are provided in front of each group of detection rollers 20, and a group of driving assemblies 40 are provided on the side of each group of detection rollers 20. Several buzzers 607 corresponding to the detection rollers 20 are provided on the upper part of the walking bracket 10.

[0059] When the walking bracket 10 moves along the road surface, the detection range of the road surface can be increased by setting up a plurality of detection rollers 20, and when the plurality of detection rollers 20 roll along the road surface, the corresponding plurality of driving components 40 can drive the plurality of cleaning components 30 to move synchronously, so as to clean out the sand and gravel debris on the road surface in front of the plurality of detection rollers 20 from the rolling path of the plurality of detection rollers 20, thereby improving the accuracy of the road surface detection structure; when a group of detection rollers 20 rolls to a raised or recessed road surface position, the corresponding buzzer 607 sends an alarm signal to remind the staff.

[0060] Since the detection roller 20 is provided with several groups, when the corresponding buzzer 607 sends out an alarm signal, the staff will not know which group of buzzers 607 sends out the alarm signal. Figure 2 In one embodiment, a group of indicator lights 606 are connected in series on one side of each group of buzzers 607. When a group of detection rollers 20 rolls to a raised or sunken road surface position and triggers the corresponding buzzer 607 to send an alarm signal, the indicator light 606 connected in series with the buzzer 607 can also light up. With the help of the lit indicator light 606, the staff can quickly determine which group of detection rollers 20 has a road surface flatness problem.

[0061] See also Figure 1 as well as Figure 2In one embodiment, a traction bracket 102 is fixedly provided on the side wall of the traveling bracket 10 , and one end of the traction bracket 102 away from the traveling bracket 10 is connected to an external traction vehicle (not shown in the figure).

[0062] The traction vehicle is driven along the road surface, and the traction bracket 102 drags the traveling bracket 10, so that the traveling bracket 10 automatically moves along the road surface, and the detection roller 20 rolls along the road surface, thereby realizing automatic detection of the road surface flatness.

[0063] In one embodiment, a mobile highway engineering quality inspection method is provided, the method comprising the following steps:

[0064] First, the walking bracket 10 is towed by a traction vehicle to walk along the road surface, so that the walking wheel 101 and the detection roller 20 roll adaptively along the road surface. When the detection roller 20 rolls to a raised road surface, the detection roller 20 moves upward compared to the walking bracket 10, thereby driving the elastic support component 50 to compress. At this time, the alarm component 60 sends an alarm signal to remind the staff that there is a flatness defect on the road surface at the current position of the detection roller 20. When the detection roller 20 rolls to a concave road surface, the detection roller 20 moves downward compared to the walking bracket 10, and the elastic support component 50 is compressed. 0 adaptively stretches, at this time the alarm component 60 also sends an alarm signal to remind the staff that there is a flatness defect on the road surface at the current position of the detection roller 20; when the detection roller 20 rolls along the road surface, the walking bracket 10 drives the cleaning component 30 to move synchronously with the detection roller 20 in front of the detection roller 20. During the rolling process of the detection roller 20, the driving component 40 drives the cleaning component 30 to move back and forth in the front side of the detection roller 20 along the rolling direction perpendicular to the detection roller 20, thereby cleaning the sand and gravel debris on the road surface in front of the detection roller 20.

[0065] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
