Description

Technical Field

[0001] The utility model relates to the technical field of highway maintenance, in particular to a crack filling device for highway maintenance. Background Art

[0002] After completion, highways require regular maintenance, and crack repair is one of the key aspects of pavement maintenance. Initial cracks have no significant impact on pavement performance. However, as surface water and snow infiltrate, the soil near the cracks becomes water-rich, even saturated, significantly reducing pavement strength. Repeated heavy traffic loads cause scouring and focusing, which can cause the asphalt surface layer on either side of the crack to break apart, impacting the pavement's performance. This can also accelerate asphalt pavement degradation, and in severe cases, even lead to structural damage. This creates numerous challenges for highway maintenance and upkeep. Therefore, pavement cracks must be discovered and repaired promptly.

[0024] See also Figure 1-4The outer wall of the shell 1 is covered with a heat-insulating coating 4, and the shell 1 and the heat-insulating coating 4 are welded and fixed. When the heat-insulating coating 4 is energized, the temperature inside the heat-insulating coating 4 rises, which can prevent the repair material in the heat-insulating coating 4 from solidifying, thereby facilitating the discharge of the repair material. The heat-insulating coating 4 is composed of a heat-insulating coating, which can reduce the heat transfer to the shell 1, thereby preventing the shell 1 from heating up and scalding the user. The heat-insulating coating 4 is wound around the outer surface of the heat-insulating coating 4, and the top of the shell 1 is integrated with a feed port 5, and the outer side of the top of the feed port 5 is covered with a cover plate 6. The outer side of the feed port 5 and the inner side of the cover plate 6 are both threaded, and the feed port 5 is threadedly connected to the cover plate 6, and the outer side of the cover plate 6 is provided with anti-slip grooves. This arrangement makes it more convenient to add repair material, and the feed port 5 is arranged at the top of the shell 1 The top of the air pump 7 is connected to the air supply pipe 8, and the end of the air supply pipe 8 away from the air pump 7 extends into the interior of the heating inner cylinder 2. When the switch on the air pump 7 is turned on, the air pump 7 transports gas to the interior of the heating inner cylinder 2 through the air supply pipe 8, so that the pressure inside the heating inner cylinder 2 increases, and the air pressure pushes the repair material inside the heating inner cylinder 2 to be discharged. Compared with manually pushing the repair material, it is more labor-saving and convenient. A battery placement groove 9 is provided under the air pump 7, and a battery 10 is installed inside the battery placement groove 9. A handle 11 is welded on the right side of the shell 1, and the outer side of the handle 11 is provided with anti-slip grooves. The battery 10 inside the battery placement groove 9 is electrically connected to the air pump 7 and the electric heating wire 3, and the battery placement groove 9 is fixed to the outside of the shell 1. The battery 10 provides power for the electric heating wire 3 and the air pump 7, so that the use environment of the device is not restricted. A cover is provided on the surface of the battery placement groove 9 to facilitate replacement of the battery 10.

[0025] The caulking pipe 12 is installed at the bottom of the shell 1, and a rubber pad 13 is installed on the bottom surface of the caulking pipe 12. A cross slit 14 is provided in the middle of the rubber pad 13. The inner side of the top end of the caulking pipe 12 and the outer side of the lower end of the shell 1 are both provided with threads, and the caulking pipe 12 is threadedly connected to the bottom of the shell 1. This arrangement facilitates the disassembly and assembly of the caulking pipe 12. On the one hand, it is convenient to replace caulking pipes 12 of different sizes. On the other hand, after the caulking pipe 12 is removed, it is convenient to clean the inside of the heating inner cylinder 2.

[0026] Working principle: When in use, first open the cover 6, inject the repair material into the heating inner cylinder 2 through the feed port 5, install the battery 10 to power the electric heating wire 3, so that the temperature inside the heating inner cylinder 2 increases, which can prevent the repair material in the heating inner cylinder 2 from solidifying, which is conducive to the use of the repair material. Since the inner wall of the shell 1 is covered with a heat-insulating coating 4, the user will not be burned by the shell 1 when holding the handle 11. Aim the bottom of the caulking pipe 12 at the gap on the road, press the switch on the air pump 7, and the air pump 7 will be pumped through the gas pipe. 8 transports gas to the interior of the heating inner tube 2, causing the internal pressure of the heating inner tube 2 to increase. As the pressure increases, the cross crack 14 on the rubber pad 13 at the bottom of the caulking tube 12 is gradually stretched open, thereby filling the gap of the road with repair material. When the air pump 7 stops working and the pressure disappears, the cross crack 14 on the rubber pad 13 will be closed, which can prevent the repair material from flowing out. When the device is finished using, the caulking tube 12 can be removed by rotating it counterclockwise to facilitate cleaning the inside of the heating inner tube 2.
