Description

Technical Field

[0001] The utility model belongs to the technical field of asphalt road leveling, and particularly relates to an adjustable asphalt road leveling device. Background Art

[0002] Asphalt road leveling equipment is a type of equipment used for road surface leveling, commonly used in road construction and maintenance. Its technical background stems from the demands of road construction and maintenance, as well as the requirements for road smoothness and quality. Asphalt road leveling equipment primarily consists of a leveling roller and a compacting roller. The leveling roller is primarily used to smooth the asphalt road surface, while the compacting roller is used to compact the asphalt road's structural layer to achieve sufficient density. However, a problem with asphalt road leveling equipment is that the height of the road surface compaction structure is not adjustable, making it difficult to adjust the compaction force. Because compaction requirements vary from road to road, it is sometimes necessary to adjust the compaction force based on the road's conditions. However, since the compacting roller of an asphalt road leveling equipment has a fixed height and cannot be adjusted, adjusting the compaction force becomes difficult, a problem that affects the quality of road construction and maintenance. Excessive compaction force can cause the asphalt road surface to crack or deform, affecting the road's service life. Conversely, insufficient compaction force may not achieve sufficient density, affecting the road's smoothness and load-bearing capacity. Utility Model Content

[0012] Beneficial effects of the utility model:

[0013] 1. Existing asphalt road leveling devices have difficulty adjusting the roller height, which makes it difficult to adjust the roadside leveling pressure. This device adjusts the pressing height by extending or contracting the output end of the first adjustment cylinder to drive the tail roller frame to rotate around the bracket connection end. Similarly, extending or contracting the output end of the second adjustment cylinder drives the extension rod to rotate around the rotating shaft to adjust the pressing force. This solves the problem of existing asphalt road leveling devices having difficulty adjusting the roadside leveling pressure due to the inconvenient roller height adjustment.
