Problems solved by technology

Using this kind of equipment to detect the roughness has few sampling points and cannot comprehensively and objectively evaluate the road smoothness; there are also disadvantages such as being greatly affected by human factors, low precision, low efficiency, and high cost.
Among the cross-section testing equipment, the currently more advanced testing equipment is the vehicle-mounted laser flatness detector, which has fast detection speed, reliable data, and high precision, but the measurement accuracy is affected by the bumps and vibrations of the testing vehicle.
[0005] The detection speed of response detection equipment is fast, but the accuracy is low, because this type of detection equipment cannot directly measure the elevation of the longitudinal section of the road surface, and it is necessary to convert its detection index and the detection index of the section type

Embodiment 1

[0041] see Figure 1-11 As shown, the present invention is a laser radar device for road flatness detection, including a fixed component, a mobile platform 4 and a crossbar 6; the fixed component is installed on the railing on the side of the road, and a horizontal crossbar is installed between the two fixed components rod 6; the mobile platform 4 moves along the cross rod 6 to detect the road smoothness;

[0042] like Figure 4-5 As shown, the fixing assembly includes a fixing base 1, a mounting base 2 and a clamping member 3; the two fixing bases 1 are relatively clamped on the railing for fixing; one side of the fixing base 1 is provided with a fixing groove 103 that cooperates with the railing; the fixing groove The two sides of the open end of 103 are symmetrically arranged stepped grooves 1031 for matching with different types of rectangular railings, and the middle of the fixing groove 103 is an arc-shaped groove 1032 for matching with circular railings;

Embodiment 2

[0051] Embodiment 2: A method for using a lidar device for road smoothness detection, comprising the following steps:

[0052] Stp1, the staff selects the corresponding number of fixed components and cross bars 6 according to the length of the road to be measured;

[0053] Stp2, the staff fixes the fixed component on the railing on the side of the road to be tested, and then fixes the crossbar 6 between the two fixed components;

[0054] Step 3. Install the mobile platform 4 on the fixed component on the most side, start the detector 5 to start detection, and drive the mobile platform 4 to move along the cross bar 6 and the clip 3 through the driving wheel 402 until the end of the fixed component on the other side. , and then run in reverse to the end of the other side, and do this for many times to complete the detection; the average value of multiple detections is taken to improve the detection accuracy.

Abstract

The invention discloses a laser radar device for road flatness detection, and the device is characterized in that fixing assemblies are installed on a handrail on the side of a road, and a cross rod is installed between the two fixing assemblies; the mobile platform moves along the cross rod to detect the road flatness; the two fixing seats are oppositely clamped on a handrail for fixing; the mounting seat is mounted on one side surface of the fixed seat; a clamping piece for fixing the cross rod is mounted on the mounting seat; the mobile platform is movably mounted on the cross rod or the clamping piece, and a detector is mounted on the outer side surface, close to the road, of the mobile platform; and a laser radar and a camera are mounted on one surface of the detector. According to the road flatness detection device, the transverse rod is fixed to a handrail on the side of a road by arranging the fixing assembly, the fixing base can be fixed to handrails of different shapes by arranging the fixing groove formed by the stepped groove and the arc-shaped groove, the use range of the device is expanded, and flatness detection is conducted on the road by arranging the moving platform loaded with the laser radar.

Description

technical field [0001] The invention belongs to the technical field of road detection, and in particular relates to a laser radar device used for road flatness detection. Background technique [0002] Flatness refers to the measurement of the unevenness of the road surface within the specified standard indicators, which is an important indicator to measure the quality of road construction and service level. The quality of the road smoothness affects the service life of the road, the loss of transportation vehicles, the transportation cost and the transportation safety, and the road slope is also an important factor affecting the road quality. Therefore, how to measure the road smoothness quickly, effectively and accurately And monitoring road slope has become a very meaningful subject nowadays. [0003] Existing pavement flatness testing equipment mainly includes two categories: cross-section flatness testing equipment and response flatness testing equipment. [0004] The ...
