Simulation calibration device of laser flatness instrument
The invention discloses a simulation calibration device of a laser flatness instrument. The device comprises a chassis, a road surface simulation platform, two mutually parallel longitudinal supporting plates and supporting plate brackets, two groups of transverse sliding rails are respectively arranged on the left side and the right side of the chassis, and the supporting plate bracket capable of sliding is arranged on the transverse sliding rails; the two longitudinal supporting plates which are parallel to each other are respectively arranged on the supporting plate brackets on the left side and the right side; the pavement simulation platform is arranged on the chassis and is positioned between the two longitudinal supporting plates; and a plurality of lifting columns are embedded in the pavement simulation platform. By adjusting the ascending and descending number of the lifting columns on the pavement simulation platform, the device can simulate various pavements with different flatness for testing, the accuracy of a calibration result is improved, vibration is applied to a detection vehicle through a vibration exciter, bumping and vibration generated when the detection vehicle runs on a road are simulated, and the real use environment of the laser flatness instrument is perfectly restored, so that the calibration precision is improved. In-situ calibration work of the laser flatness instrument is achieved, the defects in the prior art are overcome, and the accuracy and efficiency of the calibration work are greatly improved.
本发明公开了一种激光平整度仪的模拟校准装置，包括底盘、路面模拟平台、两条相互平行的纵向托板、托板支架，所述底盘左右两侧各设有两组横向滑轨，所述横向滑轨上设有可以滑动的托板支架，所述两条相互平行的纵向托板分别设置于左右两侧的托板支架上；所述路面模拟平台设置于底盘上，位于两条纵向托板之间；所述路面模拟平台上嵌设有若干升降柱。本发明通过调整路面模拟平台上升降柱升起与下降的数量，从而使得装置可以模拟多种不同平整度的路面进行测试，提高校准结果的准确性，并且通过激振器对检测车施加振动，模拟出检测车在道路上行驶时产生颠簸和振动，完美的还原了激光平整度仪的真实使用环境，从而提高了校准的精度。本发明实现了激光平整度仪的原地校准工作，解决了现有技术的不足，大大提高了校准工作的准确度和效率。
