Description

Technical Field

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

[0002] Asphalt pavement is a variety of pavement types formed by paving and rolling asphalt concrete. Asphalt concrete is a mixture of asphalt with a certain viscosity and appropriate dosage, and mineral aggregates of a certain grade, thoroughly mixed together. As an asphalt pavement material, asphalt concrete must withstand the repeated loads of moving vehicles and the long-term effects of environmental factors during use. Therefore, asphalt concrete must not only have a certain bearing capacity but also excellent durability against the elements. After asphalt pavement construction, it is necessary to use a compactor to prevent loosening of the paving materials after laying.

[0003] When using an existing asphalt pavement compactor, the compactor needs to repeatedly compact the asphalt pavement to achieve the purpose of compacting the asphalt pavement. However, the multiple passes make the construction efficiency low and also increase the construction cost. Summary of the Invention

[0004] The utility model provides an asphalt pavement compactor for municipal roads, so as to solve the technical problem of low construction efficiency proposed in the above background technology.

[0006] A buffer mechanism is provided between the roller frame and the auxiliary wheel frame. The buffer mechanism comprises a damper, one end of the damper is connected to the roller frame, the other end is connected to the auxiliary wheel frame, and a spring is externally mounted on the damper.

[0007] As an improvement to the above technical solution, the outer surface of the auxiliary wheel is integrally formed with protrusions, and the protrusions are arranged in a dot matrix.

[0008] As an improvement of the above technical solution, the rotating part includes two shaft plates welded at the rear end of the auxiliary wheel frame, and a shaft sleeve welded at the front end of the roller wheel frame. A shaft rod is rotatably installed in the shaft sleeve, and both ends of the shaft rod are rotatably connected to the shaft plates.

[0009] As an improvement of the above technical solution, the buffer mechanism also includes rotating plates welded at both ends of the damper, and the two rotating plates are rotatably mounted on the roller frame and the auxiliary wheel frame respectively, and the two ends of the spring are respectively welded on the two rotating plates.

[0010] The beneficial effects of the utility model are:

[0011] 1. A compaction mechanism consisting of a main compaction member and an auxiliary compaction member is used to pre-compact the asphalt pavement, and the main compaction mechanism is used to perform secondary compaction on the asphalt pavement, thereby improving the compaction of the asphalt pavement by the roller, reducing the number of times the roller travels on the asphalt pavement, and improving road construction efficiency. A buffer mechanism is provided between the main compaction mechanism and the auxiliary compaction mechanism, and the buffer mechanism includes a damper between the main compaction member and the auxiliary compaction member, and a spring externally connected to the damper, so that the damper can buffer the main compaction member and the auxiliary compaction member. After the damper is deformed, it is reset by the spring, so that the buffer mechanism can buffer the auxiliary compaction member at the front end of the main compaction member.

[0012] 2.
