Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, in particular to a crack repairing and flattening device for highway construction. Background Art

[0002] Highway construction projects refer to the survey, measurement, design, construction, maintenance, and management of highway structures. After a highway has been driven by vehicles for a long time, cracks will appear on the surface of the highway, which usually need to be repaired to prevent the cracks from becoming too large and causing damage to the highway. At present, when traditional crack treatment devices repair cracks on the surface of highways, they mainly inject asphalt into the cracks through pipes for treatment. During the asphalt injection process, the cracks on the road surface must first be cleaned manually. Due to the inconvenience, some projects use corresponding road repair machinery instead of manual operation.

[0003] For example, the utility model patent with application number 202221892427.3 discloses a crack repair and flattening device for rural road construction and maintenance, including a base plate, a storage box is provided on the top of the base plate, a protective plate is provided inside the storage box, a motor is provided at the bottom of the protective plate, a rotating shaft is connected to the output end of the motor, a spiral blade is provided on the rotating shaft, a discharge pipe is provided on one side of the storage box, two ear plates are provided at the bottom of the base plate, a pressure roller 1 is provided between the two ear plates, a roller is provided on one side of the ear plate, a through groove is provided on the base plate, a pressure roller 2 is provided inside the through groove, two scrapers are symmetrically provided between the pressure rollers 1 and 2, an electric push rod is provided between the scraper and the base plate, a battery box is provided on one side of the storage box, a battery is provided in the battery box, two push handles are provided on one side of the top of the base plate, and a control button is provided on one push handle. The utility model has reasonable design, simple structure, and convenient use. It can flatten asphalt for the second time, improves the repair quality of the road surface, and has strong practicality.

[0004] After the above-mentioned device fills the asphalt into the gap, it will flatten the asphalt in the gap through pressure roller one and pressure roller two. However, since pressure roller one and pressure roller two are fixedly installed on the device, during the process of pushing the device to move to the position to be flattened, pressure roller one and pressure roller two will directly contact with the road surface and continuously generate friction, resulting in unnecessary wear and damage on the surfaces of pressure roller one and pressure roller two, thereby reducing the service life of the pressure rollers.

[0005] Therefore, it is necessary to provide a crack repairing and flattening device for highway construction to solve the above technical problems. Utility Model Content
