[0002] Pavement smoothness refers to the deviation of the longitudinal concavity and convexity of the road surface. As an important indicator in pavement evaluation and pavement construction acceptance, pavement smoothness mainly reflects the smoothness of the pavement longitudinal section curve. Pavement smoothness is related to driving safety, comfort, the impact force on the pavement and its service life. With the continuous improvement of my country's highway grades and the increasingly perfect high-grade highway network, it is a very important process to test and evaluate the pavement quality.

[0027] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0029] See also Figures 1 to 6 As shown, this embodiment provides a road surface flatness detection device, including a device body 1, a connecting seat 2 is fixed on the side of the device body 1, a moving wheel 6 is installed under the device body 1, a working box 3 and a servo electric cylinder 4 are fixed on the device body 1, and a fixing seat 8 is connected to the connecting head of the servo electric cylinder 4.

[0030] Furthermore, two servo electric cylinders 4 are provided, and the two servo electric cylinders 4 are controlled by the same switch to ensure that the two servo electric cylinders 4 work synchronously. The fixed seat 8 is fixedly connected to the two servo electric cylinders 4, and the fixed seat 8 is suspended below the device body 1 through the two servo electric cylinders 4. The two servo electric cylinders 4 can ensure that the state of the fixed seat 8 is stable.

[0031] The fixed seat 8 is connected with the movable seat 5 through it, and an adjustment component for moving the movable seat 5 is arranged between the movable seat 5 and the fixed seat 8 .

[0032] Furthermore, the adjustment component includes a drive motor 7 and a drive gear 12. The drive motor 7 is installed on the fixed seat 8, and the drive gear 12 is installed in the fixed seat 8. The drive gear 12 forms a rotating structure in the fixed seat 8 through the drive motor 7 to ensure that the drive gear 12 is in a stable rotation state in the fixed seat 8.

[0033] Furthermore, two movable seats 5 are centrally symmetrically arranged on the fixed seat 8, and the movable seat 5 is meshingly connected with the driving gear 12. The movable seat 5 is a movable structure on the fixed seat 8 through the driving gear 12, and the movement of the movable seat 5 on the fixed seat 8 can be freely controlled. In this way, the combined working length of the two movable seats 5 can be freely changed, so that the device can be suitable for roads of different widths, thereby facilitating the completion of road surface flatness detection in one time.

[0034] A grounding assembly for contacting the ground is installed on the movable seat 5, and a blowing assembly for blowing the ground is arranged between the grounding assemblies.

[0035] Furthermore, the grounding assembly includes a grounding rod 10, a spring 9 and a limit block 11. The grounding rod 10 passes through the movable seat 5. The spring 9 is sleeved on the grounding rod 10. The limit block 11 is fixed to the end of the grounding rod 10. The grounding rod 10 forms an upper and lower movable structure on the movable seat 5 through the spring 9 and the limit block 11, which can ensure that the grounding rod 10 is in a stable contact state with the ground when it contacts the ground, and can freely return to its original state when it leaves the ground, thereby ensuring that the next detection work can be carried out normally.

[0036] Furthermore, the grounding rods 10 are evenly spaced on the moving seat 5 to ensure the accuracy of the road surface flatness detection result. The limit block 11 at the upper end of each grounding rod 10 is directly opposite the distance sensor 13, and the distance sensor 13 is installed on the moving seat 5. A data storage device is also provided in the working box 3, which is electrically connected to the distance sensor 13 and can record the distance data measured by each distance sensor 13. By transmitting the data to an external computer, the distance measured by the distance sensor 13 can be obtained to reflect the road surface flatness.

[0037] Furthermore, the blowing assembly includes a blowing port 14 and an air pump 15. The blowing port 14 is arranged between the grounding rods 10 on the movable seat 5, and can perform blowing work on the contact position between the grounding rods 10 and the ground. The air pump 15 is installed in the working box 3, and the air pump 15 is connected to the blowing port 14 through an air duct, which effectively prevents debris from affecting the normal progress of the detection work and ensures the accuracy of the road surface flatness detection work.

[0038] Furthermore, a mobile power supply is provided in the working box 3, which can provide power to the power users of the device, ensuring the normal outdoor mobile use of the device. At the same time, the power supply can be removed for charging, ensuring the long-term continuous operation of the device.

[0039] Specifically, when using the device, it is necessary to first determine the road width of the detection position, and then drive the motor 7 to rotate the driving gear 12 in the fixed seat 8, so that the movable seat 5 moves on the fixed seat 8, so that the combined length of the movable seat 5 can be adjusted to be suitable for the road width. After the working position of the movable seat 5 is adjusted, the device body 1 is connected to the traction device through the connecting seat 2, so that the device can be moved;

[0040] After the device moves to the road surface detection position, the servo electric cylinder 4 is extended to push the fixed seat 8 downward, and the movable seat 5 moves downward accordingly, and finally the grounding rod 10 on the movable seat 5 touches the ground. Before the grounding rod 10 touches the ground, the air pump 15 inside the working box 3 blows out high-pressure gas through the blowing port 14. As the movable seat 5 moves downward, the high-pressure gas can sweep the ground, so that the debris at the road surface detection position can be cleaned, effectively preventing the debris from affecting the direct contact between the grounding rod 10 and the road surface;

[0041] As the moving seat 5 continues to move downward, the grounding rod 10 is blocked by the ground, which will squeeze the spring 9, and the limit block 11 will move upward, and then the extension of the servo electric cylinder 4 will be stopped. The position of the moving seat 5 is stable, and the distance between the moving seat 5 and the limit block 11 can be detected by the distance sensor 13. Finally, the detected distance data is transmitted to the external computer through the processor, and the road surface flatness can be intuitively reflected by comparing the detected distance data;

[0042] When it is necessary to conduct road surface inspection at another location, the fixed seat 8 can be shortened and lifted by the limit block 11, so that the position of the movable seat 5 moves upward, and the grounding rod 10 will be separated from the ground. Under the action of the spring 9 and the limit block 11, the grounding rod 10 returns to the initial state to ensure the normal operation of the next inspection position;

[0043] The above is the use process of the detection device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
