Description

Technical Field

[0001] The utility model relates to the technical field of road surface measurement, in particular to a level ruler for calibrating a multi-point common beam rutting laser detection device. Background Art

[0002] Rutting is one of the main forms of damage to high-grade highways with high traffic volume. Rutting detection is one of the important contents of road condition detection. The multi-point common beam rutting detection device has always been the mainstream detection method for road rutting. The multi-point common beam rutting detection device uses the rutting beam as the reference. By measuring the distance of each laser from the ground, the road cross-section curve can be obtained, and then the rutting depth value can be calculated. The size of the rutting depth value reflects the severity of the road rutting.

[0003] In order to obtain accurate rutting depth values, the number of cross-sectional measuring points for rutting detection is generally required to be no less than 13 points. In order to shorten the width of the rutting beam and avoid the detection vehicle being too wide, generally 2-3 lasers on both sides of the rutting beam need to be installed at an angle, and the installation position may not be on the same horizontal plane as the other vertically installed lasers.

[0004] Although each laser has design values ​​for lateral position, vertical position and angle when designing the rutting beam, due to structural processing errors and possible structural changes of the rutting beam during use, it is still necessary to calibrate the rutting beam regularly to obtain accurate laser position parameters, and then calculate accurate road cross-section values.

[0005] When calibrating the rutting beam, a level ruler is needed. The existing level ruler itself does not have the height adjustment function. When the ground is uneven, it needs to be leveled by adding pads, which is troublesome and inaccurate. In addition, the measurement points emitted by all the laser sensors of the rutting beam are not in a straight line. The existing level ruler can only set the level in one direction and cannot directly give a horizontal plane. Utility Model Content
