Description

Technical Field

[0001] The utility model relates to the technical field of crack width detection equipment, in particular to a road surface crack detection device for highway survey. Background Art

[0002] The crack width detector is mainly used to detect the width of cracks on the surface of buildings, so as to ensure the stability and safety of the building structure. The instrument is widely used in quantitative detection of crack widths in structures such as bridges, tunnels, walls, concrete pavements and metal surfaces;

[0003] Crack width detectors are generally divided into two technologies: laser measurement and endoscope measurement. Laser measurement emits a monochromatic light beam, converts it into photoelectricity and combines it with computer analysis to determine the width of the crack, while endoscope measurement uses high-definition vision and scaling technology to directly observe the inside of the crack to achieve measurement. When measuring cracks on the road surface through an endoscope, in order to ensure the accuracy of the crack width measurement data, when detecting cracks through a crack width detector, it is necessary to adjust the position of the endoscope so that the crack measurement part is displayed in the middle of the detector screen to reduce errors caused by factors such as field of view angle and light, so that the measurement results are closer to the actual value. However, since most of the existing endoscopes for measuring crack width directly contact the road surface through the base at the bottom, there will be a certain friction between the base and the road surface, which brings inconvenience to the micro-distance adjustment of the endoscope. Secondly, after long-term use, the base of the endoscope will be worn due to friction with the road surface, so that when used later, the endoscope cannot maintain a relatively horizontal posture, which affects the use of the endoscope. In addition, when using the detector to detect the width of the road crack, it is necessary to hold the detector with one hand to operate it, and it is also necessary to hold the endoscope with one hand to adjust the position, which is inconvenient to adjust and operate the detection data of the detector.
