Description

Technical Field

[0001] The utility model relates to a detection device, in particular to a road flatness detection device. Background Art

[0002] Highways are national highways, provincial highways, county roads, township roads and special roads for vehicles to pass. The road surface flatness of a highway refers to the deviation value of the longitudinal convexity of the road surface. Road surface flatness is an important indicator in road surface evaluation and road construction acceptance. It mainly reflects the flatness of the longitudinal section profile curve of the road surface. When the longitudinal section profile curve of the road surface is relatively smooth, it means that the road surface is relatively flat, or the flatness is relatively good. Otherwise, it means that the flatness is relatively poor. A good road surface requires good road surface flatness.

[0003] For the measurement of road surface flatness, the existing method is to place a straight ruler of a specified length on the road surface and directly measure the gap between the ruler and the road surface as a flatness index. This method not only requires a lot of labor and time, but also the measurement results are not accurate enough. Utility Model Content

DETAILED DESCRIPTION

[0021] The preferred technical solution of the present utility model is described in detail below in conjunction with the accompanying drawings.

[0022] Embodiment: A road smoothness detection device, such as Figure 1-4 As shown, it includes a housing 1, a controller 2, a connecting piece 3, a telescopic rod 4, a first spring 5, a fixed rod 6, a rangefinder 7, a ground-contacting wheel 8, a push rod 9, a conical tooth 16, a universal joint 17, a moving wheel 18 and a receiver 20. The top of the housing 1 is fixedly connected to the controller 2, the upper part of the housing 1 is fixedly connected to the connecting piece 3, the lower part of the connecting piece 3 is slidably connected to the telescopic rod 4, the first spring 5 is fixedly connected between the housing 1 and the telescopic rod 4, and the first spring 5 is sleeved on the connecting piece 3, the left side of the telescopic rod 4 is fixedly connected to the fixed rod 6, and the fixed rod 6 A rangefinder 7 is installed at the other end, a receiver 20 is installed in the middle of the shell 1, and the receiver 20 is located directly below the rangefinder 7. The left and right sides of the lower part of the telescopic rod 4 are rotatably connected with ground-contacting wheels 8, and the outer ring of the ground-contacting wheel 8 is provided with a rubber ring to reduce the wear of the ground-contacting wheel 8. A push rod 9 is fixedly connected to the rear side of the shell 1, and the front and rear sides of the lower part of the shell 1 are symmetrically rotatably connected with universal joints 17. The two sets of universal joints 17 on the front side are fixedly connected with conical teeth 16 at one end close to each other, and the two sets of universal joints 17 on the front side are fixedly connected with a moving wheel 18 at one end away from each other.

[0023] like Figure 1 and Figure 5 As shown, it also includes a pushing rack 10, a sliding rod 11 and a second spring 12. The sliding rod 11 is fixedly connected to the front side of the shell 1, and the pushing rack 10 is slidably connected to the lower part of the sliding rod 11. The second spring 12 is connected between the pushing rack 10 and the sliding rod 11, and the second spring 12 is sleeved on the sliding rod 11.

[0024] like Figure 2 and Figure 3 As shown, it also includes a servo motor 13, a transmission shaft 14 and a sweeping disc 15. The servo motor 13 is connected to the middle of the front part of the housing 1 by bolts, the lower part of the output shaft of the servo motor 13 is fixedly connected to the transmission shaft 14, the lower part of the transmission shaft 14 is fixedly connected to the sweeping disc 15, and a gear is provided on the upper part of the sweeping disc 15. The two conical teeth 16 on the front side are meshed with the gears on the sweeping disc 15.

[0025] like Figure 1-Figure 4 As shown, the controller 2 is also electrically connected to the servo motor 13 and the distance meter 7 .

[0026] like Figure 3 As shown, a shock absorbing member 19 is also included, and the shock absorbing member 19 is installed between the housing 1 and the universal joint 17 .

[0027] When it is necessary to detect the flatness of the road, first place the device on the road, then push the device forward through the push rod 9, the moving wheel 18 starts to rotate, and at the same time, the servo motor 13 and the rangefinder 7 are started through the controller 2. The servo motor 13 drives the sweeping disc 15 to rotate through the transmission shaft 14. Because the sweeping disc 15 is provided with a gear on the upper part and is meshed with the two conical teeth 16 on the front side, the rotation of the sweeping disc 15 drives the conical teeth 16 to rotate, so as to achieve the effect of assisting the moving wheel 18 to rotate. When encountering a pothole section, the shock absorber 19 makes the moving wheel 18 vibrate more smoothly, and then the universal joint 17 adjusts the influence caused by the change in the direction of the moving wheel 18. While the ground-contacting wheel 8 rotates along the road surface, the rangefinder 7 starts to measure the flatness of the road surface through the receiver 20. When the ground-contacting wheel 8 encounters a pothole section, the telescopic rod 4 will rise and fall accordingly, and the first spring 5 will be adjusted accordingly.

[0028] When encountering an obstacle in front, the pushing rack 10 can push larger obstacles to the sides. When encountering an object that is difficult to push away, the pushing rack 10 moves upward through the sliding rod 11, and the second spring 12 is compressed. After pushing the obstacle away, the second spring 12 rebounds to achieve the reset of the pushing rack 10, and the sweeping disc 15 can sweep away smaller obstacles, so that the measurement result is more accurate. After the detection result comes out, the servo motor 13 and the rangefinder 7 can be turned off through the controller 2.
