Abstract
Description
Technical Field
[0001] This utility model relates to the field of highway crack treatment technology, and more specifically, to a highway crack treatment device for highway engineering. Background Technology
[0002] Highways refer to public roads between cities, between urban and rural areas, and in rural areas that have been inspected and approved by the transportation authorities and are suitable for motor vehicle traffic. Highways include highway bridges, highway tunnels, and highway ferries. Highway cracks refer to discontinuous cracks that appear on the road surface or in the base layer. These cracks can affect vehicle safety, reduce the service life of the road, and may require significant resources for repair. Highway cracks are usually caused by a variety of factors, such as quality problems with construction materials, uneven settlement of the foundation, temperature changes, and vehicle loads. Cracks can appear in various parts of the road, such as the surface, base layer, or subbase layer.
[0003] When cracks appear in asphalt pavements, asphalt grouting and surface treatment are typically used to restore the pavement. Patent application CN118639515A discloses a highway crack treatment device for highway engineering, including a trolley with a storage tank. The storage tank contains an asphalt and a material heating and mixing mechanism. A spray gun and its support mechanism are located on the left side of the trolley's top. A crack-pressing and leveling mechanism is located below the trolley. The material heating and mixing mechanism heats and stirs the asphalt in the storage tank to prevent it from solidifying and affecting its use. The crack-pressing and leveling mechanism allows a roller to roll on the repaired pavement, while a scraper removes asphalt or other substances adhering to the outer wall of the roller, keeping the roller clean and improving the smoothness of the asphalt at the crack.
[0004] However, in the highway crack treatment equipment used in the above-mentioned highway engineering projects, the heater and heat conduction plate are set at the bottom of the storage tank, which can easily lead to uneven temperature of the asphalt in the storage tank and insufficient temperature of the upper layer of asphalt, thereby affecting the fluidity of the asphalt.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] like Figure 1 As shown, the highway crack treatment device for highway engineering in this embodiment includes a mobile trolley. A storage tank 1 is mounted on top of the trolley, with a feed inlet 2 at the top and containing crack filler. A material mixing mechanism is installed inside the storage tank 1. A crack filling spray gun 3 and a crack filling lifting mechanism that raises and lowers the spray gun 3 are mounted at the front of the trolley. The bottom of the storage tank 1 is connected to the crack filling spray gun 3 via a conveying pipe 4, which is equipped with a conveying pump 5. A crack pressing and leveling mechanism and a pressing and lifting mechanism that raises and lowers the crack pressing and leveling mechanism are mounted below the trolley. The conveying pipe 4 is a flexible hose.
[0030] In this embodiment, combined with Figure 2 and Figure 3 As shown, a heat preservation and heating mechanism is also provided around the storage tank 1. The heat preservation and heating mechanism includes an insulation layer 6 and a heating band 7. The insulation layer 6 surrounds the storage tank 1, and the heating band 7 is spirally embedded in the insulation layer 6. The spiral heating band 7 heats the sealant in the storage tank 1, and the sealant in the upper and lower parts of the storage tank 1 is heated evenly.
[0031] In this embodiment, as Figure 3 As shown, the material mixing mechanism includes a mixing shaft 8, spiral mixing blades 9, and a mixing drive assembly. The mixing shaft 8 is vertically arranged inside the storage tank 1, with its upper end penetrating through the storage tank 1, and its lower end rotatably connected to the bottom of the storage tank 1. The spiral mixing blades 9 are fixedly arranged on the outside of the mixing shaft 8, and the mixing drive assembly is arranged on the top outside of the storage tank 1 and is used to drive the mixing shaft 8 to rotate. Specifically, the mixing drive assembly includes a drive motor 13, a drive gear 14, and a driven gear 15. The drive motor 13 is arranged on the top surface of the storage tank 1, the drive gear 14 is fixed on the output shaft of the drive motor 13, and the driven gear 15 is fixed on the mixing shaft 8. The drive gear 14 and the driven gear 15 mesh.
[0032] The drive motor 13 drives the active gear 14 to rotate, which in turn drives the driven gear 15 and the stirring shaft 8 to rotate. This causes the spiral stirring blades 9 to rotate and stir the sealant in the storage tank 1, making the sealant flow horizontally and vertically, thereby making the temperature of the sealant in the storage tank 1 more uniform.
[0033] In this embodiment, the material mixing mechanism further includes connecting rods 10 and scrapers 11.

The U-shaped frame 20 is located at the lower end of the pressing and lifting mechanism, and the roller 21 is rotatably mounted inside the U-shaped frame 20. A heating wire 22 is installed inside the roller 21. Specifically, in conjunction with... Figure 5 , Figure 6 and Figure 7 As shown, the heating wire 22 is an electric heating wire, spirally arranged inside the roller 21. Both ends of the heating wire 22 are connected to first conductors 30. The end of the first conductor 30 furthest from the heating wire 22 is connected to a first conductive plate 31, which is coaxially arranged with the roller 21.
