Description

Technical Field

[0001] This invention relates to the field of highway crack treatment technology, and in particular to a highway crack treatment device for highway engineering. Background Technology

[0002] Highway cracks are cracks or fissures that form on the road surface. The occurrence of highway cracks is mainly caused by the following factors: natural factors, climate change is the main natural factor leading to highway cracks. For example, high temperatures cause the road surface to expand, while low temperatures cause it to contract. These periodic changes can cause the road surface to crack. Traffic load, traffic load refers to the load applied to the road surface during vehicle travel. Frequent vehicle travel and the load of heavy vehicles can cause stress concentration on the road surface, thereby causing cracks to form.

[0003] Existing crack treatment devices mainly repair cracks on highway surfaces by injecting asphalt into the cracks through pipes. During the asphalt injection process, the cracks must first be manually cleaned to prevent debris from obstructing the subsequent asphalt injection and flattening process. Secondly, the asphalt used for repair will seep out from both sides of the crack, resulting in a waste of raw materials.

[0004] However, current methods for treating cracks in highway engineering often require manual identification of the crack location, which is time-consuming and labor-intensive, greatly increasing the time required to treat highway cracks and the cost of highway maintenance, which is not conducive to the long-term use and maintenance of highways.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this invention can be combined with each other. The described embodiments are merely some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this invention. The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] like Figs. 1 to 4 As shown, the present invention provides a highway crack treatment device for highway engineering, comprising:

[0032] A purge assembly is used to remove debris from the road surface.

[0033] A crack identification component, comprising multiple pressure detection tentacles, is used to determine the location of a crack based on the detected pressure value.

[0034] A crack treatment component is used to treat cracks based on the crack location determined by the crack identification component.

[0035] The mobile base, the purging component, the crack identification component, and the crack treatment component are sequentially arranged at the bottom of the mobile base, and the purging component is arranged at the head end of the mobile base.

[0036] In use, this invention uses a blowing component to clean debris from the road surface, preventing debris from interfering with the crack identification component's detection of road crack locations. The pressure detection probe of the crack identification component contacts the road surface. When the pressure detection probe touches the crack location, if it cannot detect a pressure value or the detected pressure value is significantly lower than that detected by other pressure detection probes, the crack location can be determined through the pressure detection probe. The crack treatment component can then treat the crack based on the crack location determined by the crack identification component, eliminating the need for manual confirmation of the crack location. This significantly reduces the time required to treat highway cracks and lowers highway maintenance costs.

[0037] To further optimize the solution and avoid the impact of residual material on the road surface on the smoothness of the road surface when treating cracks, the road crack treatment device for highway engineering provided by the present invention also includes a scraping component, which is used to scrape the material that overflows onto the road surface when the crack treatment component treats the crack.

[0038] To further optimize the solution, in order to facilitate the blowing away of debris on the road surface and prevent debris from affecting the smoothness of the road surface and thus affecting the crack recognition component's ability to identify the crack location, the blowing component includes an air pump 1. The air pump 1 is fixedly installed on the top of the mobile base. The air outlet of the air pump 1 is fixedly connected to an air distribution box 2. The air distribution box 2 is fixedly connected to the bottom of the mobile base, and the air distribution box 2 is set perpendicular to the forward direction of the mobile base. Multiple air outlet pipes 3 are fixedly connected at equal intervals at the bottom of the air distribution box 2.

[0039] Further optimizing the scheme, the crack detection component includes a first telescopic cylinder 4, which is fixedly installed at the bottom of the movable base. A first mounting frame 5 is fixedly connected to the bottom of the first telescopic cylinder 4. A rotating shaft 6 is rotatably connected to the first mounting frame 5. The rotating shaft 6 is perpendicular to the forward direction of the movable base. A mounting sleeve 7 is fixedly sleeved on the rotating shaft 6. Multiple sets of pressure detection tentacles are fixedly connected to the outer wall of the mounting sleeve 7 along the central axis. Multiple pressure detection tentacles in the same set are equally spaced along the circumference of the mounting sleeve 7. A motor 8 is fixedly installed on the first mounting frame 5, and the motor 8 rotates in cooperation with the rotating shaft 6.

[0040] The crack identification component also includes a controller, and the pressure detection tentacles and crack handling components are all electrically connected to the controller.

[0041] The design is further optimized so that the pressure detection contact includes a fixed rod 9, which is fixedly installed on the mounting sleeve 7. A sliding sleeve 10 is fixedly connected to the end of the fixed rod 9. A pressure sensor 11 and a spring 12 are installed inside the sliding sleeve 10. The pressure sensor 11 is fixedly installed on the fixed rod 9. The two ends of the spring 12 abut against the pressure sensor 11 and the sliding sleeve 10 respectively. The pressure sensor 11 is electrically connected to the controller.

[0042] The pressure detection tentacles are driven by motor 8 to rotate shaft 6, allowing different tentacles to contact the road surface. When the tentacles are in normal contact with the road surface, the pressure sensor 11 inside the tentacles detects the pressure. When the tentacles contact cracks, the pressure sensor 11 detects a significantly lower pressure than when in normal contact with the road surface. This pressure value is transmitted to the controller, which determines the location of the crack. Furthermore, the contact pressure between the tentacles and the road surface can be adjusted by extending and retracting the first telescopic cylinder 4. After determining the crack location, the controller controls the crack processing component based on the crack location, the forward speed of the moving base, and the distance between the crack processing component and the crack identification component, thereby processing the cracks on the road surface.

[0043] To further optimize the scheme and ensure effective identification of cracks affecting the bearing capacity and durability of the road surface, the maximum diameter of the pressure detection probe shall not exceed 0.2 mm, and the distance between two adjacent pressure detection probes and the road surface along the circumferential direction of the mounting sleeve 7 shall not exceed 1 cm.

[0044] To further optimize the scheme, the arrangement of the pressure detection contacts can be either overlapping of two adjacent pressure detection contacts along the circumference of the mounting sleeve 7, or staggered arrangement of two adjacent pressure detection contacts along the circumference of the mounting sleeve 7.

[0045] Further optimization of the scheme: the crack treatment component includes a material tank 13, which is located at the top of the movable base. A slurry pump is installed inside the material tank 13, and the outlet end of the slurry pump is connected to a discharge pipe 14. The end of the discharge pipe 14 is connected to a discharge nozzle 15. A second mounting bracket 16 is fixedly connected to the bottom end of the movable base. A lead screw device 17 is fixedly connected to the second mounting bracket 16. The lead screw device 17 is arranged parallel to the rotating shaft 6. The discharge nozzle 15 is fixedly installed on the slider 18 of the lead screw device 17. Both the lead screw device 17 and the slurry pump are electrically connected to the controller.

[0046] After the controller determines the location of the crack based on the pressure value detected by the pressure detection tentacles, the controller controls the lead screw device 17 to adjust the position of the slider 18 according to the crack location information, so that the discharge nozzle 15 on the slider 18 is aligned with the crack location. Then the controller controls the slurry pump to work and realize the crack treatment work.

[0047] Further optimization of the scheme: the leveling component includes a second telescopic cylinder 19, which is fixedly installed at the bottom of the movable base. A third mounting bracket 20 is fixedly connected to the bottom of the second telescopic cylinder 19. A scraper 21 is fixedly connected to the bottom of the third mounting bracket 20. The scraper 21 is set perpendicular to the forward direction of the movable base. Both ends of the scraper 21 are fixedly connected to baffles 22.

[0048] In a further optimized design, a battery pack 23 is fixedly connected to the top of the mobile base. The battery pack 23 is used to power the electrical equipment in the highway crack treatment device.

[0049] The design is further optimized. The mobile base includes a base plate 24. The blowing component, crack identification component, crack treatment component and leveling component are all installed on the base plate 24. The bottom end of the base plate 24 is fixedly installed with a moving wheel 25. The end of the base plate 24 away from the blowing component is fixedly connected with a handle 26.

[0050] The highway crack treatment device for highway engineering provided by the present invention uses an air pump 1 to provide high-pressure air, and uses the high-pressure airflow blown out by the air outlet pipe 3 to clean up debris on the road surface, ensuring the cleanliness of the road surface and avoiding affecting the pressure detection tentacles' identification of cracks. The pressure detection tentacles determine the location of cracks based on the pressure when in contact with the road surface. The controller drives the lead screw device 17 and the slurry pump to treat the cracks based on the identified crack location. If slurry overflows onto the road surface after treatment, the slurry on the road surface is scraped smooth by the scraper 21 as the moving base moves, avoiding affecting the smoothness of the road surface.

[0051] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
