Technical Field

[0001] The present application relates to the technical field of crack detection, and in particular to a municipal road crack detection device. Background Art

[0002] Detect cracks on the road so that timely repairs and maintenance can be carried out to ensure the safety and durability of the road.

[0003] In the prior art, such as China Publication No. CN215722272U, the utility model discloses a road crack detection device, including a cross bar, a lifting mechanism body, a first motor, a support rod, a bottom rod, a roller, a sliding member, a stabilizing device, a connecting mechanism and a detection device body. The utility model is provided with a connecting mechanism at the front end of the bottom of the sliding member, and the bottom of the connecting mechanism is connected to the detection device body. The connecting mechanism is connected and fixed by means of a plug-in buckle, which is manually operated, fast to assemble and disassemble, and has strong stability after connection; a stabilizing device is provided at the rear end of the bottom of the sliding member, and the stabilizing device is driven by an independent motor. When driven, the components inside the box are transmitted, so that the contact plate at the front end can be pushed out to contact the back of the detection device body, and the detection device is stably supported to avoid shaking during movement and affecting the detection effect.

[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that when detecting road cracks, some use laser scanners to scan the road surface to measure the depth, width and length of the cracks. Sometimes the road cracks are blocked by debris, dust and other materials, and these debris are not cleaned up, which reduces the accuracy of the detection results. In addition, in order to facilitate the movement of the laser scanner, it is installed on a mobile cart, and the detection is facilitated by pushing the mobile cart. Some are installed on the cart by snap-on method, and laser scanners of different sizes cannot be installed. Utility Model Content

[0050] Working principle: Before detecting road cracks, the laser scanner 309 is placed on one side of the placement frame 3, and the two second sets of rods 302 can slide inside the two first sets of rods 301 respectively. At this time, the laser scanner 309 is placed between the first pressure plate 304 and the second pressure plate 308 by pushing the first pressure plate 304. At this time, the elastic force generated by the two telescopic springs 303 pushes the first pressure plate 304, so that the first pressure plate 304 and the second pressure plate 308 clamp the laser scanner 309. At this time, the rotating plate 307 drives the threaded rod 306 to rotate, and further pushes the second pressure plate 308, so that the first pressure plate 304 and the second pressure plate 308 fix the laser scanner 309 on the mobile trolley 1, thereby installing the laser scanner 309 on the mobile trolley 1. The installation method is simple, and laser scanners 309 of different sizes can be fixed, thereby improving the practicability of the device. When detecting road cracks, the device is pushed to the detection point. When detecting cracks at the measuring location, the limit rod 204 is pulled out. At this time, one side of the two extrusion springs 203 is on one side of the two circular plates 205. The elastic force generated by the two extrusion springs 203 pushes the two connecting plates 201 toward the ground side, thereby pushing the support plate 202, and further making one side of the bristles of the two cleaning brushes 210 close to the ground. At this time, the external power supply of the driving motor 207 is turned on, and then the output shaft of the driving motor 207 drives the first rotating rod 208 to rotate, and further makes one of the second rotating rods 209 and one of the pulleys 211 rotate, and the other pulley 211 is rotated through the belt 212, so that the two second rotating rods 209 drive the two cleaning brushes 210 to rotate, and at this time, the entire detection device is pushed, and the two rotating cleaning brushes 210 first clean the cracks in the road, and then the laser scanner 309 detects the road. The road cracks are clearly visible, which improves the accuracy of detection and reduces the possibility of misjudgment and missed detection.
