Abstract
Description
Technical Field
[0001] This utility model relates to the field of road maintenance equipment technology, and in particular to a grooving device for road maintenance. Background Technology
[0002] Road maintenance grooving equipment is a specialized tool that uses mechanical cutting to create regular grooves on the road surface. By removing damaged asphalt or concrete, it provides a clean base for repair materials. The regular grooves enhance the adhesion between new and old materials, improve repair accuracy and efficiency, extend the service life of the road, and reduce the cost of repeated maintenance.
[0003] In the prior art, such as Chinese Publication No. CN222961868U, this utility model relates to the field of road grooving technology, specifically a road maintenance grooving machine. It includes a base plate with a groove in the middle. Slide rails are fixedly connected to both sides of the groove, and a protective frame is slidably connected between the slide rails. A cutting wheel is rotatably connected inside the protective frame, and a movable protective plate is rotatably connected to the rear side of the protective frame. The advantages of this utility model are: by providing a movable protective plate with a torsion spring on the rear side of the protective frame, when the equipment is adjusted to align with the grooving position, the movable protective plate automatically tilts up under the action of the torsion spring, allowing the operator to directly observe the alignment position of the cutting wheel. This makes adjusting the cutting position of the grooving machine more convenient. After alignment, pressing down on the movable protective plate merges it with the rear opening of the protective frame, providing full coverage and protection for the outer side of the cutting wheel. Furthermore, pressing down on the protective plate applies force to the road surface, improving the stability of the device during grooving.
[0004] While the above-mentioned solutions have the advantages mentioned above, their disadvantages lie in the lack of a structure that allows for adjustment of the grooving angle of the device based on the actual angle of the road surface cracks and the actual grooving conditions. When facing complex and varied road surface cracks, the fixed-angle grooving mechanism cannot accurately match the crack direction, which can easily lead to grooving position deviation or insufficient depth. This results in poor adhesion between the repair material and the original road surface, shortening the repair life. Furthermore, the fixed-angle equipment requires frequent shutdowns for manual adjustment of the machine's posture, affecting the efficiency of road repair. Utility Model Content
