Description

Technical Field

[0001] The present invention relates to the technical field of road surface quality detection devices, and more specifically, to a road surface quality detection method and system. Background Technique

[0002] Highway engineering refers to the work of surveying, measuring, designing, constructing, maintaining, and managing highway structures. With the development of society, the number of highway projects has gradually increased. During the construction of highway projects, it is necessary to detect the quality of the road surface. Generally, a sampling device is first used to drill holes and sample the road surface for quality detection.

[0003] In the prior art, a road surface quality detection device and method with the publication number of CN118997102B, which relates to the technical field of highway engineering, includes: a base, a support frame is fixedly installed on the top of the base, a support plate is fixedly installed on the top of the support frame, a driving device is fixedly installed on the top of the support plate, a screw rod is fixedly installed at the output end of the driving device, and a moving frame is threadedly installed on the circumferential surface of the screw rod; a support device, the support device is arranged on the surface of the support frame, the support device includes a fixed rod, the fixed rod is fixedly installed on the top of the base, a semi-circular plate is fixedly installed on the surface of the moving frame, a motor is fixedly installed at the bottom of the moving frame, a gear is fixedly installed at the output end of the servo motor, a sampling drill barrel is fixedly installed at the bottom of the semi-circular plate, a tooth ring is fixedly installed on the circumferential surface of the sampling drill barrel, and the surfaces of the gear and the tooth ring are engaged. The device is fixed by moving the fixing nails downward into the soil to prevent the device from moving during operation.

[0004] However, when the existing road surface quality detection device is in use, although it can perform sampling and detection operations on the road surface well, the number of sampling rods used is relatively fixed. When it is necessary to perform area detection on different areas of the road surface, the synchronization of multi-point adjustment detection of the road surface to be detected is reduced, the efficiency of road surface quality detection is reduced. At the same time, after a single sampling rod samples the sample, it is necessary to stop the machine to perform the blanking operation of the sample. The convenience of blanking the sample without stopping the whole device is not high, which increases the complexity of the staff using the detection device and does not meet the usage requirements of people. For this reason, we propose a road surface quality detection method and system. Summary of the Invention

The rotation center of the intermittent turntable 407 is fixedly connected to a connecting shaft 410 extending below the control box 3. The end of the connecting shaft 410 is fixedly connected to an adjusting rod 5. When performing quality detection on the road surface, in order to improve the effect of synchronous detection of different orientations of the road surface and the flexibility of continuous sampling detection of the road surface without stopping the machine, according to the needs of the detection state, the servo motor 401 can be turned on. Through the rotation of the driving gear 402, the connecting gear 403 is driven to perform a rotational motion.

Through the fixed connection of the limiting rod 8, the lifting block 9 is driven to perform a lifting motion, and the sampling rod is driven to perform a synchronous lifting motion, playing a role in conveniently detecting and sampling the road surface;

[0062] Next, when drilling and sampling the road surface, in order to improve the synchronous dust reduction effect of the sampling area, the water pump 14 can be turned on. Through the connection of the connecting hose 15, the water resources in the water tank 13 are driven to spray out from the dust reduction nozzle 16, achieving the effect of conveniently dust-reducing construction in the sampling area;

[0063] Finally, when moving the detection device to the road surface to be detected, the second electric push rod 1701 can be turned on, driving the lifting rod 1702 to slide along the inner wall of the lifting groove 1703, and driving the sliding rod 1704 to retract along the inner wall of the device, so that the universal roller 1705 retracts into the inner wall of the device, achieving the effect of accommodating the universal roller 1705, playing a role in improving the contact between the device and the road surface, and improving the stability of the construction of the detection device.
