[0030] The present utility model will be described in detail below in conjunction with the specific implementation manners shown in the drawings. However, these implementation manners do not limit the present utility model, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these implementation manners is included in the protection scope of the present utility model.

[0031] Such as Figures 1-6As shown in the figure, this embodiment proposes a crack repair device for highway engineering, which includes a vehicle body. In some embodiments, the chassis of the vehicle body is formed by welding several groups of angle irons into a rectangular structure. Steel plates or templates are laid inside the rectangular angle irons. Rotatable wheels are connected to the periphery of the rectangular angle irons for easy pushing and moving. A stirring kettle is arranged on the vehicle body. The stirring kettle is connected to an asphalt heat preservation pump 1. The input end of the asphalt heat preservation pump 1 is connected to the stirring kettle to facilitate sucking the asphalt inside it. The output end of the asphalt heat preservation pump 1 is connected to an asphalt output pipe 3. The asphalt output pipe 3 extends outside the vehicle body. A protective cover 15 is welded at the position where the input end of the asphalt heat preservation pump 1 is connected to the stirring kettle to prevent it from being damaged by external collisions and causing asphalt leakage due to damage to the input end of the asphalt heat preservation pump 1;

[0032] Furthermore, the stirring kettle includes a kettle body 21. An inner tank 22 is arranged inside the kettle body 21. The inner tank 22 serves as a container for storing asphalt. A kettle top cover 23 that can be opened and closed is also arranged above the kettle body 21. When needed, the top cover can be opened to fill the asphalt into the inner tank 22. During the repair process, the top of the kettle body 21 is closed through the kettle top cover 23. On the one hand, it prevents asphalt leakage, and on the other hand, it ensures the temperature inside the inner tank 22 to avoid asphalt solidification; A rotating motor 24 is arranged above the kettle top cover 23. The output shaft of the rotating motor 24 is connected to a spline shaft 25. The spline shaft 25 is rotatably placed inside the inner tank 22. A bearing is arranged at the bottom inside the inner tank 22. The outer ring of the bearing is fixed to the bottom of the inner tank 22, and the inner ring of the bearing is detachably connected to the spline shaft 25 to allow the spline shaft 25 to rotate inside the inner tank 22; It also includes a scraping disc 26 that can move up and down along the spline shaft 25. Several groups of stirring telescopic rods 27 are connected to the bottom of the scraping disc 26. The stirring telescopic rods 27 are structures with manually adjustable telescoping. Weights 28 are hung at the bottom of the stirring telescopic rods 27.

[0033] During the process of repairing highway cracks, in order to keep the asphalt in good fluidity, usually, the stirring kettle is used to stir the asphalt while filling the asphalt into the cracks. For example, a highway crack repair device with the patent application number 202323039122.5 and a pavement crack treatment device with the patent application number 202420112040.4 both adopt the construction method of stirring while repairing. After the actual construction is completed, the asphalt adhering to the inner wall cannot be filled into the cracks, which will cause a certain waste, and it is even more difficult to clean after it hardens. Based on this, in the present utility model, during the process of rotating and stirring to fill the cracks, the scraping disc 26 is designed to be a structure that can move up and down. The asphalt on the inner wall of the inner tank 22 is scraped by the scraping disc 26, and the scraped asphalt is filled into the cracks through the asphalt heat preservation pump 1 for effective utilization, avoiding waste and other phenomena, and it can also save the step of cleaning the side wall of the inner tank 22 in the future, reducing the cost of subsequent construction cleaning and maintenance.

[0034] In some embodiments, a flexible material with high temperature resistance and wear resistance is coated around the scraping disc 26 to achieve efficient cleaning and thorough scraping of the inner wall of the inner container 22.

[0035] In some embodiments, a spline sleeve 212 is fixedly connected to the inner circle of the scraping disc 26. The spline sleeve 212 is sleeved on the outer circumference of the replacement part and can move up and down along the spline shaft 25. When the driving motor drives the spline shaft 25 to rotate, the spline shaft 25 further drives the spline sleeve 212 and the scraping disc 26 to rotate. At the same time, the cooperation between the spline sleeve 212 and the spline shaft 25 can also enable the scraping disc 26 to move up and down along the spline shaft 25 to scrape the inner wall of the inner container 22.

[0036] Reference Figures 5 to 6 , in some embodiments, at least two groups of electric telescopic rods 29 are commonly connected between the scraping disc 26 and the kettle top cover 23. A circular guide rail 210 is fixedly connected to the top surface of the scraping disc 26. An annular groove is formed in the circular guide rail 210. The end of the electric telescopic rod 29 is fixedly connected with a slider 211. The slider 211 is slidably arranged in the annular groove, so that when the scraping disc 26 rotates, the slider 211 at the end of the electric telescopic rod 29 placed in the circular guide rail 210 can drive the scraping disc 26 to move up and down along the spline shaft 25.

[0037] In some embodiments, there is a certain space between the kettle body 21 and the inner container 22 for arranging a heating wire 4. The heating wire 4 can be fixed between the kettle body 21 and the inner container 22 by several methods such as bolts or binding. The heating wire 4 further heats the asphalt in the inner container 22 to keep it in good fluidity and prevent it from solidifying inside the inner container 22, which affects the construction process.

[0038] Reference Figure 4 , in some embodiments, an anti-overflow box 5 is detachably connected to the asphalt output pipe 3. The anti-overflow box 5 can be fixed to the asphalt output shaft by several methods such as binding. The anti-overflow box 5 has an open structure at the top and bottom. A spring 6 is connected inside the anti-overflow box 5. The other end of the spring 6 is connected with a smoothing ball 7. The smoothing ball 7 is placed behind the asphalt output pipe 3. The end of the anti-overflow box 5 is in an arc-shaped structure; during the process of the asphalt output pipe 3 spraying asphalt to fill the crack, as the vehicle moves forward, the rear smoothing ball 7 smooths and squeezes the asphalt in the crack under the action of the spring 6, so that it is fully filled into the crack. At this time, the upper part of the asphalt is in an arc-shaped concave shape, and part of the asphalt overflows to both sides of the crack. The anti-overflow box 5 gathers the overflowed asphalt and fills it above the squeezed asphalt, so that the surface of the crack remains flat after filling.

[0039] In some embodiments, a support frame 138 is further provided on the vehicle body, and a power supply 9 is placed below the support frame 138. The power supply 9 is electrically connected to the rotation motor 24, the asphalt heat preservation pump 1, the heating wire 4, the electric telescopic rod 29, etc. to provide a power source for them. A storage box 10 is detachably connected above the support frame 138. The storage box 10 can be fixed on the support frame 138 by bolts or the like. A push handle 11 is further provided on the support frame 138, and a controller 12 is connected to the push handle 11. The controller 12 is used to control the operation of components such as the rotation motor 24, the asphalt heat preservation pump 1, and the electric telescopic rod 29.

[0040] In some embodiments, a support frame 138 is fixedly connected to the bottom of the kettle body 21. A handle 14 is circumferentially connected to the support frame 138. The bottom of the support frame 138 is detachably placed on the vehicle body. The kettle body 21 is lifted by the support frame 138 so that the bottommost part of the inner liner 22 and the asphalt heat preservation pump 1 are at a relatively high position, which is convenient for the asphalt in the inner liner 22 to be completely discharged during the crack repair process.

[0041] In some embodiments, a bumper beam 16 is fixed to the front section of the vehicle body. The bumper beam 16 is of a U-shaped structure. The bumper beam 16 is used to prevent the vehicle body from directly colliding with obstacles in front, damaging the vehicle body and affecting its progress.

[0042] The working steps of this device are as follows:

[0043] Open the top cover 23 of the kettle, fill the asphalt into the inner liner 22, and then close the top cover 23 of the kettle. Heat the asphalt in the inner liner 22 through the heating wire 4 to keep it in a good flowing phase. Then start the rotation motor 24, drive the scraping disk 26 to rotate by the spline shaft 25, and further drive the stirring telescopic rod 27 below the scraping disk to rotate to stir the asphalt in the inner liner 22;

[0044] Push the vehicle body to the area to be repaired, align the asphalt output pipe 3 with the crack, shield the area around the crack through the anti-overflow box 5, and then pump out the asphalt in the inner liner 22 through the asphalt heat preservation pump 1 and fill it into the crack through the asphalt output pipe 3. Move forward while filling. During the forward movement, the leveling ball 7 squeezes and levels the asphalt filled in the crack, so that the asphalt is fully poured into each area in the crack. The asphalt in the crack is concave in an arc shape above after being squeezed by the leveling ball 7, and part of the asphalt is squeezed to both sides of the crack. As the vehicle body drives the anti-overflow box 5 forward, the end of the anti-overflow box 5 gathers the overflowing asphalt and fills it above the squeezed asphalt, so that the surface of the crack remains flat after repair;

[0045] During the patching process, as the asphalt in the inner tank 22 decreases, the electric telescopic rod 29 is activated to push the scraping plate 26 downward. During the downward movement of the scraping plate 26, the asphalt adhering to the inner wall of the inner tank 22 is scraped off, and the stirring telescopic rod 27 is squeezed and shortened downward. Without affecting the stirring efficiency of the stirring telescopic rod 27, the scraping plate 26 is moved downward to scrape off the asphalt until all the asphalt in the inner tank 22 is used to fill the cracks, avoiding waste and other phenomena, so that the asphalt in the inner tank 22 can be fully utilized.

[0046] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
