Description
Technical field
The utility model content belongs to road quality checkout gear technical field, relates to a kind of multifunctional laser pavement checkout gear of estimating surface evenness, rut index that is used to detect.
Background technology
At present, adopt a plurality of probe laser displacement sensor technology to carry out the laser pavement detection system of pavement detection, modal a kind of form of structure is that a plurality of laser displacement sensors are installed on a crossbeam, wherein be located at two laser displacement sensors on the wheel path respectively with corresponding accelerometer combination, nationality detects with the planeness of carrying out two wheel paths, is installed in the rut that other laser displacement sensor that crossbeam makes progress then is used on the transverse direction and detects.Such laser pavement detection system can detect planeness and two indexs of rut simultaneously.
Adopt many probe laser displacement sensor technology to carry out pavement detection, advantage is that detection speed is fast, precision is high.But the maximum technological difficulties that this type of laser pavement detection system runs in use are: detection speed is can not be too slow, cannot This vehicle stops frequently, and detection speed can not be lower than a certain limiting velocity, and these conditions limitations are all brought very big inconvenience to use.In the actual detected process of road, often run into situations such as maintenance of surface maintenance, vehicle and road travel, it is usually slower to detect travel speed, and travel speed generally all is lower than 30km/h, and when running into the traffic jam situation, road speed can be slower.When above-mentioned situation occurred, existing laser pavement detection system was often inaccurate to the testing result of planeness, need remeasure.Even in the detection to ordinary highway, when running into when travelling at a slow speed, its testing result also often can't adopt, and often is required heavily to examine.When running into crossroad traffic lights parking during the pavement detection of this external urban road, adopt this type of detection system also can't finish testing.The existing in a word gait of march of laser pavement detection system in testing process can not be too slow, can not This vehicle stops frequently, also cannot do anxious the acceleration or anxious Reduced Speed Now certainly.
The utility model content
The purpose of this utility model is the problem that prior art exists is solved, provide a kind of rational in infrastructure, easy to use, accuracy of detection is high and the unrestricted multi-functional symmetrical expression laser pavement checkout gear of detection speed.
Be used to realize that the technical solution of the utility model purpose is: the multi-functional symmetrical expression laser pavement checkout gear that is provided has one by a left side, right vertically planeness detects Liang Heqian, the rectangle roof beam structure that back hack lever connects to form, the middle part of rectangle roof beam structure frame be equipped with a pair by the lower end anyhow the U type rut that constitutes of frame and two side stands detect crossbeam, on the frame anyhow of rut detection crossbeam, be arranged side by side 15～20 laser displacement sensors that can send the collimation detection laser beam downwards, detect at rut on two side stands of crossbeam by on the next respectively be provided with 3～6 successively can be below tiltedly outer or closely send the laser displacement sensor that collimates detection laser beam below straight, two vertical planeness detect the top that the beam correspondence is located at road surface left and right sides wheel path, on two vertical planeness detection beams, respectively be provided with 5 laser displacement sensors that can send the collimation detection laser beam downwards, the laser displacement sensor at one of them laser displacement sensor and rut detection crossbeam outermost end place is shared, all the other four rear and front ends that are located at vertical planeness detection beam by grouping in twos respectively.
In the real work, the rectangle roof beam structure that U type rut detection crossbeam is housed longitudinally can be installed on the checkout gear of pulling or be installed on the detection vehicle in the road surface.When checkout gear with car to overtake the time, by be located at all laser displacement sensors on the horizontal detection beam to the shift value of some datums and all laser displacement sensors to the computing of the difference of the actual detected value in cross section, some road surfaces, the horizontal rut distribution situation in road surface can be described out.Obviously, the laser displacement sensor quantity on the horizontal detection beam on the transverse direction is many more, and the cross section rut curve of description is accurate more.Meanwhile, each laser displacement sensor that is located on left and right vertical planeness detection beam wheel path longitudinally detects the distance of beam body to the road surface simultaneously, the data that collect machine are as calculated carried out after data handle, just can detect the roughness index on road surface fast and accurately, as international roughness index IRI etc.In this apparatus structure, because to a left side, the planeness of right both sides wheel path detects and adopts laser displacement sensor to carry out fully, each laser displacement sensor that the vertical planeness in a left side detects on the beam during work is done the front and back detection along same longitudinal section, each laser displacement sensor that right vertically planeness detects on the beam is also done the front and back detection along same longitudinal section, dependency relation according to existing between the laser displacement sensor detection data on dependency relation that exists between the laser displacement sensor detection data on the vertical planeness detection in the left side beam and the right vertically planeness detection beam can obtain surface evenness information on the wheel path of the left and right sides by the data processing.Owing to do not adopt acceleration, so detecting all, the planeness of the left and right sides has nothing to do with travel speed, thereby also irrelevant with this symmetrical expression laser pavement checkout gear of forming with detection speed.
Compare with the checkout gear of laser displacement sensor combination with the accelerometer of present employing, the utility model proposes a kind of flat detection method of laser pavement of whole employing laser displacement sensors, its main feature is the influence that the planeness on two wheel paths detects not examined substantially speed speed, but testing process This vehicle stops frequently, can soon can be slow, the maintenance that is not only applicable to speedway detects, also be applicable to the quick and slow detection of arterial highway, but more can be applicable to the requirement of the This vehicle stops frequently in the urban road detection; And adopt symmetrical expression laser pavement checkout gear of the present utility model, and not only can detect the planeness of two wheel paths, horizontal rut, also both can be combined and carry out the road pavement form measurement.
