Description

Technical Field

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

[0002] Highway engineering structures include roadbed, pavement, bridges, culverts, tunnels, drainage systems, safety protection facilities, greening and traffic monitoring facilities, as well as houses, workshops and other service facilities used for construction, maintenance and monitoring. Among them, the pavement is an important part of highway engineering, and its quality directly affects the comfort and safety of driving. The pavement mainly includes cement concrete, asphalt concrete, various asphalt-treated crushed stone and gravel materials, sand and gravel or crushed stone mixtures and blocks mixed with soil, etc. Among them, asphalt concrete pavement has become a commonly used highway pavement today due to its good performance and low cost.

[0003] However, after long-term use, asphalt pavement will be damaged by cracks, dents, etc. due to vehicle overloading, lack of maintenance, etc., which will affect the flatness of the road and driving comfort. If the road surface is not repaired in time, it will affect driving safety and even cause traffic accidents. Therefore, cracks and damages on the road surface need to be repaired in time.

[0004] Existing road crack repair equipment cannot heat asphalt during use. In low temperature environments, asphalt caking is easily caused, which is not conducive to road repair and results in poor smoothness of the repaired road surface. In addition, although some existing solutions use heating modules both outside and inside the asphalt heating cylinder, in the actual asphalt heating process, since the height of the material added to the asphalt cylinder is different each time, and the heating wires or heating rods in the heating module are evenly arranged, when the asphalt material in the asphalt heating cylinder is stacked at different heights, some of the heating wires in the heating module are far away from the asphalt material, and as the heating process proceeds, the asphalt melts into a fluid, causing the material height to further decrease. This defect will be more significant, which will seriously affect the heating efficiency and cause heating waste.

[0005] In addition, the existing road crack repair equipment cannot adjust the position of the discharge port according to the location of the crack, and the asphalt mixture cannot be vibrated and compacted after filling the crack, and the crack is usually cleaned manually in advance. These problems affect the efficiency and effect of road crack repair. Summary of the invention

DETAILED DESCRIPTION

[0038] 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.

[0039] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0040] 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.

[0041] 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.

[0042] As mentioned in the background technology, the existing road crack repair equipment cannot heat the asphalt during use. In a low temperature environment, it is easy to cause asphalt to agglomerate, which is not conducive to repairing the road surface, resulting in poor smoothness of the repaired road surface. In addition, although some existing solutions use heating modules to be set both on the periphery and inside of the asphalt heating cylinder, in the actual asphalt heating process, since the height of the material added to the asphalt cylinder is different each time, and the heating wires or heating rods in the heating module are evenly arranged, when the asphalt material in the asphalt heating cylinder is stacked at different heights, some of the heating wires in the heating module are far away from the asphalt material, and as the heating process proceeds, the asphalt melts into a fluid, causing the material height to further decrease. This defect will be more significant, thereby seriously affecting the heating efficiency and causing heating waste.

[0043] In addition, the existing road crack repair equipment cannot adjust the position of the discharge port according to the location of the crack, and the asphalt mixture cannot be vibrated and compacted after filling the crack, and the crack is usually cleaned manually in advance. These problems affect the efficiency and effect of road crack repair.

[0044] In order to improve the above problems, the present application proposes a road crack repair device, which can automatically identify and locate the position of road cracks through an image sensor arranged at the bottom of the vehicle body. This automation technology reduces the need for manual intervention and improves work efficiency and accuracy. The opening position at the bottom of the mixing barrel is adjusted by a mobile component to ensure that the opening corresponds precisely to the road crack, thereby avoiding waste of asphalt mixture and improving the quality of repair. Through the fan arranged at the bottom of the vehicle body, the cracks can be blown and cleaned before filling the asphalt mixture to remove impurities and dust in the cracks, providing a clean working environment for subsequent repair work. Through the vibration component arranged at the bottom of the vehicle body, the asphalt mixture can be vibrated and compacted after filling the cracks, so that the asphalt mixture and the cracks are perfectly bonded, thereby enhancing the strength and durability of the repaired road surface. The device can adapt to cracks of different heights and widths, as well as different working environments and climatic conditions, and has strong on-site applicability and flexibility. By arranging a heating strip inside the asphalt mixing tank, the heating efficiency can be improved and energy waste can be avoided.
