Description
Technical field
The utility model relates to technical field of measurement and test, especially relates to a kind of based on the measurement mechanism of sheet light to lorry side guard rail installation dimension.
Background technology
Along with China's motor vehicle rapidly increases, motor vehicle is produced to people and life brings easily simultaneously, also brings the potential safety hazard that can not be ignored.The overall liftoff height of lorry, car body is long, distance between front and back wheel is large, as cyclecar, bicycle or pedestrian and lorry generation side collision, easily causes vehicle, pedestrian is drawn under the car, cause major traffic accidents.Lorry side guard rail plays the effect of buffering suction, can effectively prevent pedestrian or compact car from piercing at the bottom of lorry car and resulting in greater loss.Chinese patent application publication No. CN102829982A, Dec 19 2012 Shen Qing Publication day, name is called the patent of invention open file of " a kind of lorry/trailer side protective device intensity detection platform and detection method ", provides a kind of lorry/trailer side protective device detection platform and detection method.It comprises: test platform, hydraulic loading mechanism and hydraulic feed system, and hydraulic loading mechanism comprises bracing frame, hydraulic cylinder and force snesor, and hydraulic cylinder is arranged on test platform upper surface by bracing frame level, is provided with force snesor in hydraulic cylinder push rod front end; Hydraulic feed system is Hydraulic Station.This technical scheme, just to lorry side guard rail intensity detection, does not detect installation site size.Although country is provided with more detailed regulation to lorry side guard rail, part lorry car owner also thinks little of side shield hurdle.If guard rail installation site and size do not meet national standard, same consequence not up to standard with truck side guard railing intensity can be there is.Current China is carry out in vehicle administration office based on artificial method to installing and measuring of lorry side guard rail mostly, and not only detection efficiency is low, metrical error large, and also inadequate to the supervision of guard rail use.
Summary of the invention
The inadequate technical matters of large and that truck protective guard the is used supervision of lorry side guard rail installation dimension error is detected in order to solve in prior art, the utility model provides a kind of lorry side guard rail installation dimension measurement mechanism based on sheet light, detect to reach convenient, detection data are accurate, strengthen object guard rail being used to supervision.
The technical solution of the utility model is: a kind of lorry side guard rail installation dimension measurement mechanism based on sheet light, it comprises frame, video camera, line laser light source and tested guard rail, frame upper end is provided with guide rail, slide is connected with slide plate, video camera and line laser light source are fixed with slide plate respectively, line laser light source sends sheet illumination and is mapped to tested guard rail, and the camera optical axis of video camera becomes angle α with the optical plane of sheet light, and video camera is electrically connected with computing machine.Video camera and the rectilinear movement of line laser light source synchronous, automatically record lorry side guard rail installation dimension, by the concrete numerical value of output detections guard rail after computer disposal to front and back wheel, vehicle upper component and ground distance.Structure is simply closed, easy to operate, and usable range is wide.Strengthen using supervision to guard rail.Measuring accuracy is high, detects data accurate, improves detection efficiency.
As preferably, rail end is connected with sensor assembly, and sensor assembly comprises limit sensors and distance measuring sensor, and limit sensors is positioned at rail end, and distance measuring sensor is positioned at the camera same side of frame and video camera; Prevent video camera and line laser light source impaired, guarantee that lorry side guard rail is in surveyed area.
As preferably, the value of angle α is 45 °-60 °; Guarantee to detect data accurate.
Compared with prior art, the beneficial effects of the utility model are: lorry one enters in test specification, just automatically can detect the distance of truck protective guard to front and back wheel, vehicle upper component and ground, and output display in time.Structure is simply closed, easy to operate.Use occasion is extensive, supporting with banister, does not take up room, and strengthens using supervision to truck protective guard.Measuring accuracy is high, detects data accurate, improves detection efficiency, alleviates testing staff's labour intensity.
