[0002] During road construction, flatness is an important indicator for measuring road quality, which can affect driving comfort and safety. Therefore, the flatness of the road surface must be tested during road inspection to ensure that the flatness of the road surface meets the requirements. In the process of testing the flatness of the road surface, a road surface flatness detection vehicle is needed.

[0003] Existing road surface roughness detection vehicles are usually composed of detection vehicles, rollers, detectors and other components. When the road surface roughness detection vehicle is driving on the road for detection, there are often stones, garbage and other debris on the road surface, which will cause the rollers to run over the debris, thus affecting the accuracy of the device in measuring the roughness. Therefore, we propose a road surface detection device to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A road pavement detection device includes a detection body 1, and rollers 8 are equidistantly installed at the bottom end of the detection body 1. The connection method of the detection body 1 and the rollers 8 is the existing technology. In addition, the detection body 1 is driven by a tractor for detection, and the connection method between it and the tractor is also the existing technology. No further explanation is given here. A first cleaning plate 2 is provided at the front end of the detection body 1, and a second cleaning plate 3 is distributed on the side of the first cleaning plate 2. Brushes 4 are evenly distributed on the bottom end of the second cleaning plate 3, and a limiting mechanism is provided at the top end of the second cleaning plate 3.

[0023] Further, see Figure 2 and Figure 3 It can be known that the limiting mechanism includes a connecting strip 5, which is arranged on the side of the second cleaning plate 3, and the outer side of the connecting strip 5 is symmetrically connected to the limiting rod 6, and the limiting rod 6 is respectively inserted at the top position of the second cleaning plate 3, and the interior of the first cleaning plate 2 is provided with a limiting groove adapted to the limiting rod 6, and the limiting grooves are distributed at the upper and lower ends of the first cleaning plate 2. When the two groups of limiting rods 6 are engaged in the limiting grooves on the lower side of the first cleaning plate 2, the brush 4 is able to contact the road surface to achieve cleaning of the road surface. When the two groups of limiting rods 6 are engaged in the limiting grooves opened on the upper side of the first cleaning plate 2, the brush 4 no longer contacts the road surface, thereby achieving the storage of the brush 4.

[0024] Further, see Figure 3 It can be known that a spring 7 is symmetrically connected to the top of the second cleaning plate 3, and the other end of the spring 7 is connected to the connecting strip 5. The spring 7 is sleeved on the outside of the limiting rod 6. Through the connection of the spring 7, the tightness of the limiting rod 6 in the first cleaning plate 2 can be effectively guaranteed.

[0025] Further, see Figure 2 and Figure 3 It can be seen that the top of the second cleaning plate 3 is symmetrically connected with a guide block 9, and the side of the first cleaning plate 2 is provided with a guide groove 10 adapted to the guide block 9. Through the mutual cooperation of the guide block 9 and the guide groove 10, the vertical guidance of the second cleaning plate 3 can be achieved to ensure the reliability of the second cleaning plate 3 during the movement.

[0026] Further, see Figure 2 and Figure 4It can be known that a clamping block 11 is connected to the top of the first cleaning plate 2, and the clamping block 11 is sleeved on the outside of the detection vehicle body 1, a threaded rod 12 is inserted into the inside of the clamping block 11, and the end of the threaded rod 12 is connected to a rotating block 13, a clamping groove matched with the threaded rod 12 is opened inside the detection vehicle body 1, and a threaded groove matched with the threaded rod 12 is opened inside the clamping block 11. When in use, the mutual cooperation between the clamping block 11 and the threaded rod 12 can facilitate the staff to disassemble the damaged first cleaning plate 2 or brush 4 for replacement, so as to effectively improve the convenience of the maintenance process of the device.

[0027] Further, see Figure 4 It can be known that the card block 11 is set as a U-shaped structure, and the inner side of the card block 11 is symmetrically connected with a card strip 14, and the outer wall of the detection vehicle body 1 is provided with a positioning groove adapted to the card strip 14. When the first cleaning plate 2 and the detection vehicle body 1 are docked, the staff can first insert the card strip 14 connected to the inner side of the card block 11 into the positioning groove opened inside the detection vehicle body 1, so that the position of the threaded rod 12 can correspond to the position of the card slot inside the detection vehicle body 1, so that the staff can rotate the rotating block 13 to engage the threaded rod 12 into the card slot inside the detection vehicle body 1.

[0028] Further, see Figure 3 It can be known that the longitudinal section of the guide block 9 and the guide groove 10 is set as a T-shaped structure, and the outer wall of the guide block 9 and the inner wall of the guide groove 10 are tightly fitted. The guide block 9 and the guide groove 10 are set by the T-shaped structure, and because the guide block 9 and the guide groove 10 are fitted together, the stability of the second cleaning plate 3 during movement can be further guaranteed.

[0029] Working principle: When the utility model is in use, the staff can first connect the detection vehicle body 1 and the tractor, and the detection vehicle body 1 can be driven to the designated detection area by the tractor. When the detection vehicle body 1 arrives at the detection area, the staff can first pull the connecting strip 5, so that it drives the limiting rod 6 to be pulled out from the inside of the first cleaning plate 2, and then the staff can pull down the second cleaning plate 3, so that the guide block 9 connected to its side slides inside the guide groove 10. When the brush 4 connected to the bottom end of the second cleaning plate 3 is pushed to contact the road surface, the position of the limiting rod 6 can correspond to the position of the limiting groove opened at the bottom end of the first cleaning plate 2, and the limiting rod 6 can be inserted into the limiting groove at the bottom end of the first cleaning plate 2. The detection vehicle body 1 and the roller 8 can be driven by the tractor to travel on the road surface and perform detection. When the detection vehicle body 1 and the roller 8 are traveling, the road surface can be cleaned by the brush 4 connected to the bottom end of the second cleaning plate 3. Since the second cleaning plate 3 and the brush 4 are arranged in a V-shaped structure, the cleaned debris can be guided to the side of the device to prevent the roller 8 from rolling on the debris and affecting the measured data. After the detection is completed, the staff can pull the connecting strip 5 again to make the limiting rod 6 engage with the limiting groove provided at the top end of the first cleaning plate 2, so that the brush 4 no longer contacts and rubs against the ground. The above is the entire working principle of the utility model.

[0030] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

[0031] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
