Description

Technical Field

[0001] The utility model belongs to the technical field of highway quality detection, and more specifically, particularly relates to a flatness detection device. Background Art

[0002] When testing the quality of highway pavement engineering or assessing road conditions, an eight-wheel smoothness meter is needed to detect the position of the highway wheel track. When measuring, you need to first use a ruler to measure the distance between the test wheel and the lane marking to determine the measurement position, and then use a pickup truck to pull the eight-wheel smoothness meter to move for testing. When the measuring distance is relatively short, in order to avoid repeated disassembly and assembly, most staff members directly hold the fixed rod with their hands for measurement.

[0003] For example, CN220867928U discloses a detector for detecting the smoothness of a highway, comprising a fixed frame, the bottom of which is rotatably connected to a rotating rod, and one end of the rotating rod is fixedly connected to a mounting plate; the advantage is that when detecting the road surface, the motor is started to rotate the fixed plate to make the rotating block slide in the slide groove to push the mounting plate, and one end of the mounting plate causes the rotating block to reciprocate and push the mounting plate to swing left and right through the rotation of the fixed plate, so that the bottom brush sweeps away the debris to both sides to avoid affecting the measurement of the measuring wheel, and the moving wheel is provided with a shock absorbing device to make the device more stable when moving, thereby improving the accuracy of the measurement of the measuring wheel, and when the brush needs to be replaced, the handle rotates the connecting rod to make the threaded surface separate from the mounting plate, and then the brush is pulled out for replacement, and when installing, the connecting rod is passed through one end of the brush plate to make the threaded surface threadably connected to the mounting plate, so that the brush plate is installed and fixed, and it is more convenient to replace the brush.

[0004] Based on the above, it is difficult for a pickup truck to always travel in a straight line when moving. When the driving trajectory of the pickup truck deviates, it is easy to cause the detection wheel to deviate, affecting the accuracy of the road surface flatness detection results, and further affecting the use effect of the detection device.
