Multifunctional laser detector for planeness of road surface

The utility model relates to a multi-function laser detection device for detecting the evenness of the road surface, the device is provided with an outer framework with walking wheels. A rigid detection beam under which a plurality of laser displacement sensors are arranged is hung on the inner circumference of the outer framework through a plurality of springy shock-absorbing objects. A hinge folding draw frame, a withdrawing shading protection panel and so on are also arranged on the outer framework. The utility model adopts a datum transferring measuring method and detects the road surface through full optical laser displacement sensors. The laser displacement sensors detect the distance to the surface while the device moves. The collected data is received and stored by a computer directly after preprocessed by an interface control case. The product has the advantages of low price, convenient use, fast, objective and accurate detection and high efficiency, etc.
