Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to an asphalt pavement corner compactor. Background Art

[0002] Asphalt pavement is a common road paving material, which is popular for its good wear resistance, anti-skid and durability. It is a composite material made of asphalt, aggregate (such as crushed stone, gravel, etc.) and other additives, and is constructed through paving and compaction processes. After the pavement is laid and compacted, the compaction force spreads to the outside during compaction, resulting in some uncompacted parts at the corners of the pavement, which need to be compacted using a separate device.

[0003] The "Asphalt Pavement Corner Compactor" disclosed in patent publication number "CN220318312U" includes a frame, a traveling assembly is provided below the frame, and the movement of the entire device is achieved through the traveling assembly. A tamping seat is fixedly installed on the lower surface of the frame, and connecting plates are fixedly installed on both sides of the tamping seat. A tamping column is rotatably installed on the lower surface of the connecting plate, and the bottom surface of the tamping column is coplanar with the lower surface of the tamping seat. The tamping seat is a hollow structure, and an oscillation assembly is provided inside the tamping seat, and the tamping seat is vibrated up and down by the oscillation assembly. During the entire use process, when the corners of the road with curbstones installed are compacted, the friction is reduced by the contact between the rotatable tamping column and the curbstone. In this way, wear can be reduced while ensuring that the corners of the road can be compacted, and excessive friction can be avoided to scratch the curbstone, while also reducing the travel resistance. In comparison, the function is more complete.

[0004] In response to the above-mentioned related problems, when compacting the corners of the road surface, it can only compact in the upper and lower directions. During compaction, it cannot prevent the asphalt at the corners from diffusing outward when under pressure, causing the asphalt at some corners to further diffuse outward during compaction, thereby affecting the compaction effect.

[0005] To this end, the utility model provides an asphalt pavement corner compactor to solve the above problems. Utility Model Content
