Description

Technical Field

[0001] This utility model relates to the technical field of road repair devices, specifically to a crack repair device for highway maintenance. Background Technology

[0002] Currently, highway maintenance typically involves repairing cracks, usually by filling them with asphalt. However, after filling the cracks with asphalt, the area is often left exposed to the elements. In cold and humid weather, this negatively impacts the asphalt's drying and setting efficiency, leading to longer road closures and increased likelihood of traffic congestion, thus adversely affecting road traffic. Utility Model Content

[0003] The purpose of this invention is to address the problem that the drying and solidification efficiency of asphalt is adversely affected when the weather is cold and humid, resulting in a decrease in the drying efficiency of asphalt. This invention provides a crack repair device for highway maintenance.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: A crack repair device for highway maintenance includes a support cylinder, a bearing cylinder at the upper end of the support cylinder, a mobile power supply box fixedly installed inside the support cylinder, multiple ventilation holes on the side wall of the bearing cylinder, an air blowing mechanism fixedly installed on the bearing cylinder, a ventilation hose fixedly installed on one side of the air blowing mechanism, and a crack protection mechanism provided on one side of the ventilation hose.

[0005] Preferably, the air blowing mechanism includes an air box, one side of which is fixedly mounted on a bearing cylinder, and an air blower is fixedly mounted on the side wall of the air box. A support pipe is embedded in the side wall of the air box, and one end of the support pipe is connected to the air outlet of the air blower.

[0006] Preferably, an electric heating plate is fixedly installed on the side wall of the ventilation box, and the electric heating plate is located at the upper end of the ventilation box.

[0007] Preferably, a wire-passing hole is provided on the side wall of the bearing cylinder, and the wire-passing hole is located on the central side wall at the bottom end of the bearing cylinder.

[0008] Preferably, the crack protection mechanism includes multiple U-shaped covers, wherein each of two adjacent U-shaped covers has a rotating hole, and a connecting plate is provided between the two U-shaped covers. The two ends of the connecting plate have symmetrically arranged snap-fit ​​holes, and a connecting shaft is rotatably installed in each of the two snap-fit ​​holes. The two connecting shafts are respectively rotatably installed in the rotating holes of the two adjacent U-shaped covers. Rubber soft sealing plates are fixedly installed symmetrically between the two adjacent U-shaped covers. One side of each of the two rubber soft sealing plates is fixedly installed on the side wall of the connecting plate. A sealing plate is fixedly installed on the end face of one of the U-shaped covers, and one end of the ventilation hose is fixedly installed on the sealing plate.

[0009] Preferably, a U-shaped handle is provided on the side wall of the support cylinder, and the U-shaped handle is rotatably mounted on the support cylinder. A rainproof ring is fixedly installed on the side wall of the bearing cylinder, and the rainproof ring is located above the vent hole.

[0010] The beneficial effects of this utility model are as follows: 1. In this utility model, multiple U-shaped covers are fastened to the upper side of the road crack using components such as a support cylinder, a bearing cylinder, and a ventilation box. The position and angle between two U-shaped covers can be adjusted using a connecting plate and a connecting shaft. A rubber soft sealing plate seals the gap between the two U-shaped covers, thus protecting the asphalt in the crack. After the crack is filled with asphalt, the blower and electric heating plate are activated, allowing the blower to inject outside air into the ventilation box. The air is then heated by the electric heating plate and injected into the multiple U-shaped covers through ventilation hoses. This hot airflow maintains the asphalt at a suitable temperature, facilitating evaporation and drying, while reducing interference from rain and moisture, ensuring a fast drying speed, avoiding prolonged road closures, and minimizing adverse effects on road traffic.

A U-shaped handle 5 is provided on the side wall of the support cylinder 1, and the U-shaped handle 5 is rotatably mounted on the support cylinder 1, allowing for convenient carrying and movement of the repair device. A bearing cylinder 2 is provided at the upper end of the support cylinder 1, and a mobile power supply box 14 is fixedly installed inside the support cylinder 1, containing a battery pack. Multiple ventilation holes 13 are provided on the side wall of the bearing cylinder 2, and a rainproof ring 3 is fixedly installed on the side wall of the bearing cylinder 2, positioned above the ventilation holes 13. The rainproof ring 3 protects the ventilation holes 13, preventing rainwater from entering the bearing cylinder 2.

[0018] An air-blowing mechanism is fixedly installed on the bearing cylinder 2. This mechanism includes a venting box 4, one side of which is fixedly mounted on the bearing cylinder 2. A blower 16 is fixedly installed on the side wall of the venting box 4. A support pipe 17 is embedded in the side wall of the venting box 4, with one end connected to the air outlet of the blower 16. An electric heating plate 18 is fixedly installed on the side wall of the venting box 4, positioned at the top. The electric heating plate 18 heats the airflow within the venting box 4, thus achieving better drying of the asphalt. A wiring hole 15 is provided on the side wall of the bearing cylinder 2, located at the bottom center of the side wall. This wiring hole facilitates the installation and storage of various electrical component wiring harnesses.

[0019] A ventilation hose 7 is fixedly installed on one side of the bearing cylinder 2. A crack protection mechanism is provided on one side of the ventilation hose 7. The crack protection mechanism includes multiple U-shaped covers 12. Rotation holes 6 are opened on two adjacent U-shaped covers 12, and a connecting plate 8 is provided between the two U-shaped covers 12. The two ends of the connecting plate 8 are symmetrically provided with snap-fit ​​holes 9. A connecting shaft 10 is rotatably installed in each of the two snap-fit ​​holes 9. The two connecting shafts 10 are respectively rotatably installed in the rotation holes 6 of the two adjacent U-shaped covers 12.
