Description

Technical Field

[0001] The invention relates to the technical field of highway engineering, and in particular to a road surface smoothness repairing machine. Background Art

[0002] As an important part of modern transportation infrastructure, the performance of highways directly affects traffic safety, driving efficiency and comfort. Among the many indicators for evaluating highway performance, road surface smoothness is the most critical one. It is not only related to the stability and comfort of vehicle driving, but also directly affects the operating cost and maintenance cost of the vehicle. Therefore, improving road surface smoothness is of great significance to improving the overall performance of highways.

[0003] However, in the actual road construction and use process, due to the influence of various factors, such as weather conditions, construction equipment, manual operation, improper base treatment, construction joint treatment, etc., the road surface flatness may not meet the standard. In addition, the road surface flatness of the highway that has been opened to traffic will gradually deteriorate due to roadbed settlement, uneven wear, rutting, etc. These problems not only affect the performance of the highway, but also may threaten driving safety.

[0004] Traditional road repair methods often require multiple people to work together, and the equipment has poor stability and cannot automatically adjust the angle to keep it level with the road surface, which to a certain extent limits the efficiency and quality of repair. Therefore, developing a road repair device that can automatically adjust the angle and maintain stability is of great practical significance for improving the flatness of the road, reducing maintenance costs, and ensuring driving safety.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0039] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0040] As in the background technology, in actual road construction and use, due to the influence of various factors, such as weather conditions, construction equipment, manual operation, improper base treatment, construction joint treatment, etc., the road surface flatness may not meet the standard. In addition, the highway that has been opened to traffic will also gradually deteriorate due to reasons such as roadbed settlement, uneven wear, and rutting. These problems not only affect the performance of the highway, but also may threaten driving safety. Traditional road surface repair methods often require multiple people to cooperate in operation, and the equipment has poor stability and cannot automatically adjust the angle to keep it level with the road surface, which limits the repair efficiency and quality to a certain extent. Therefore, developing a road surface repair equipment that can automatically adjust the angle and maintain stability is of great practical significance for improving road surface flatness, reducing maintenance costs, and ensuring driving safety.

[0041] In order to improve the above problems, a road surface flatness repair machine proposed in this application can accurately measure and adjust the angle of the milling cutter by setting a level on the milling cutter assembly to ensure the accuracy and consistency of the milling process. This precise control can significantly improve the quality of road surface repair, make the repaired road surface smoother, reduce the vibration and impact of the vehicle during driving, and improve driving comfort. The signal processor controls the extension and retraction of the electric telescopic column, automatically adjusts the position and angle of the milling cutter, and reduces the need for manual adjustment. This automated operation mode not only improves work efficiency, but also reduces the labor intensity of the operator, making the operation more convenient and efficient. The support components at the four corners of the device are fixedly supported by the entire device after moving to the corresponding position, which enhances the stability of the equipment during operation. The stable equipment platform helps to maintain the working state of the milling cutter and avoid the decline in repair quality caused by equipment shaking, thereby ensuring the consistency of the repair effect. The adjustable height scraper can be adjusted according to different road conditions to ensure that the filled asphalt can be evenly scraped. This flexibility enables the equipment to adapt to various complex road conditions and improves the adaptability and flexibility of road surface repair. The automated adjustment and control system reduces the labor intensity of workers and reduces the dependence on operating skills. This not only improves work efficiency, but also improves the working environment, allowing workers to complete their work under more relaxed conditions.
