Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to an automatic detection structure for paving thickness. Background Art

[0002] Asphalt paving is the process of evenly applying asphalt mixture to the surface of roads, bridges, or other structures. It is a crucial step in road construction, playing a crucial role in improving road quality, extending its service life, and ensuring driving safety. The thickness of the asphalt surface layer is a key factor influencing road quality. A thicker asphalt layer provides greater wear resistance, allowing it to withstand repeated friction from vehicle tires without damage. Furthermore, a sufficient asphalt layer thickness enhances the road's compressive strength, preventing cracks and potholes from forming under heavy pressure. These factors combine to make asphalt surface thickness a crucial indicator of road quality.

[0003] After searching, the Chinese patent publication number CN205711655U discloses a real-time detection device for the paving thickness of an asphalt paver, including a measuring vehicle that travels synchronously with the paver. The measuring vehicle includes a body, a control module, an electric motor, a power transmission mechanism, a thickness detection mechanism and an alarm. The body is provided with a first displacement sensor for detecting the vehicle's travel distance, and the thickness detection mechanism is provided with a probe and a second displacement sensor for detecting the displacement of the probe.

[0004] In view of the problem that the above technology lacks the function of cleaning the detection probe, asphalt will quickly solidify at one end of the probe in relatively cold and dry weather, affecting the detection results; therefore, an automatic paving thickness detection structure is proposed.

Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0029] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] Example 1:

[0031] like Figure 1-6As shown, an automatic detection structure for paving thickness includes a sliding bracket 2 slidably connected to one end of a support plate 1, one end of the sliding bracket 2 is provided with a control component, which can control the movement of the electric components in the device and record the working data and upload it to the operation end, a hanging plate 6 is fixedly connected to the bottom of the sliding bracket 2, one end of the hanging plate 6 is fixedly connected to an air supply pipe 5 and a swing motor 7, one end of the air supply pipe 5 is fixedly connected to a cleaning plate 13, one side of the cleaning plate 13 is provided with a guide ramp 14, the cleaning plate 13 is made of rubber, one end of the swing motor 7 is fixedly connected to a lifting component, one end of the lifting component is fixedly connected to a distance measuring box 10, one end of the distance measuring box 10 is slidably connected to a distance measuring rod 15, one end of the distance measuring rod 15 is fixedly connected to a trigger box 17, and one end of the trigger box 17 is slidably connected to a detection needle 11;

[0032] During detection, the detection needle 11 can be driven downward by the lifting component, and then the detection needle 11 can be used to trigger the asphalt to touch the ground to extend the lifting component to detect the asphalt paving thickness. More accurate data can be obtained by detecting with multiple detection needles 11. After the detection is completed, the swing motor 7 can be used to drive multiple detection needles 11 to rotate, move to the middle of the cleaning plate 13 and then reset to scrape off excess asphalt on the surface. At the same time, the guide ramp 14 can prevent the detection needle 11 from getting stuck and unable to correctly enter the cleaning plate 13.

[0033] In this embodiment, one end of the detection needle 11 is fixedly connected to a lifting platform 20, and one end of the lifting platform 20 is slidably connected to a sliding joint 21. Wires 22 are fixedly connected between the multiple sliding joints 21. One end of the trigger box 17 is fixedly connected to a contact 19. The sliding joints 21 on both sides connect the contacts 19 to form a loop.

[0034] When the detection needle 11 contacts the asphalt, it will move upward due to the viscous asphalt. At this time, the lifting platform 20 is squeezed upward to disconnect the sliding joint 21 and the contact 19, thereby disconnecting the circuit. At this time, the control component can receive the signal of contact with the asphalt surface and start recording the extension distance of the lifting component.

[0035] In this embodiment, the sliding joint 21 and one end of the lifting platform 20 are fixedly connected with a spring 23, an anti-deflection groove 18 is opened inside the trigger box 17, and one end of the lifting platform 20 is slidably connected to the anti-deflection groove 18. The spring 23 can reset the sliding joint 21, and the anti-deflection groove 18 can prevent the detection needle 11 from being deflected when cleaning the detection needle 11.

[0036] In this embodiment, one end of the ranging rod 15 is fixedly connected to a reflector 25, and a ranging component 24 is fixedly connected to the interior of the ranging box 10. The ranging component 24 is preferably a reflective rangefinder. One end of the ranging rod 15 and the ranging box 10 is fixedly connected to a spring 26. One end of the ranging box 10 is slidably connected to a stabilizing rod 16, and the other end of the stabilizing rod 16 is fixedly connected to the trigger box 17.

[0037] The spring 26 is a spring with high hardness. When the detection needle 11 is pressed against the ground, the distance measuring rod 15 will move upward. At this time, when the distance measuring component 24 detects the distance change, the elongation record of the lifting component is ended to obtain the paving thickness data.

[0038] In this embodiment, the lifting assembly includes a telescopic rod 8 and a swing bracket 9. One end of the telescopic rod 8 is fixedly connected to the power output end of the swing motor 7, and one end of the swing bracket 9 is fixedly connected to the movable end of the telescopic rod 8. The telescopic rod 8 can be extended for detection, and the swing bracket 9 can drive multiple detection needles 11 for detection.

[0039] In this embodiment, one end of the sliding bracket 2 is fixedly connected to an air pump 4, the air outlet end of the air pump 4 is fixedly connected to the air supply pipe 5, and the air outlet end of the air supply pipe 5 is fixedly connected to a plurality of cleaning nozzles 12; the air pump 4 can spray air through the cleaning nozzles 12, and perform jet cleaning from both sides when the detection needle 11 swings. The detection needle 11 can be sprayed twice during one swing process to improve the cleaning effect.

[0040] In this embodiment, during testing, the detection needle 11 can be driven downward by the lifting assembly, and then the lifting assembly can be extended by the detection needle 11 between the asphalt and the ground contact to detect the asphalt paving thickness. Testing with multiple detection needles 11 can obtain more accurate data. After the test is completed, the swing motor 7 can be used to drive the multiple detection needles 11 to rotate, move to the middle of the cleaning plate 13, and then reset to scrape off excess asphalt on the surface. At the same time, the guide ramp 14 can prevent the detection needle 11 from getting stuck and unable to properly enter the cleaning plate 13.

[0041] When the detection needle 11 contacts the asphalt, it moves upward due to the viscosity of the asphalt. At this time, the lifting platform 20 is squeezed upward to disconnect the sliding joint 21 and the contact 19, thereby breaking the circuit. At this time, the control component can receive the signal of contact with the asphalt surface and start recording the extension distance of the lifting component.

[0042] Spring 1 23 allows the sliding joint 21 to reset, and the anti-deflection groove 18 prevents the detection needle 11 from deflecting when cleaning. Spring 2 26 is selected to be of high hardness. When the detection needle 11 is pressed against the ground, the distance measuring rod 15 moves upward. When the distance measuring component 24 detects the distance change, the elongation record of the lifting assembly is stopped to obtain the paving thickness data;

[0043] The air pump 4 can spray air through the cleaning nozzle 12, and perform jet cleaning from both sides when the detection needle 11 swings. The air pump 4 can spray and clean twice during one swing of the detection needle 11, thereby improving the cleaning effect.

Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention.
