Description

Practical wide width adjusting device of bituminous paving pressure Technical Field The utility model relates to the field of asphalt compactors, in particular to a wide-width adjusting device for asphalt pavement compaction. Background Along with the rapid development of urban infrastructure construction, asphalt pavements are increasingly widely applied to large-scale traffic facilities such as urban roads, airports and bridges, and a small asphalt compactor is used as one of common equipment in pavement construction, and is widely applied to compaction work of various small and medium-sized asphalt pavements due to strong maneuverability and simple operation. In asphalt pavement construction, the compaction process is a key element for ensuring the bearing capacity and durability of the pavement. In a traditional small asphalt compactor, in order to share a certain weight in the running process of the compactor, a guide roller is usually installed at the front end, the guide roller can share a certain weight and can play a role of precompaction, but the structure of the guide roller is generally fixed, the size of the guide roller cannot be regulated, the single size limits the application of the guide roller in asphalt pavement compacting operation with different widths, and especially in the condition of needing to treat pavement with different widths, the fixed guide roller design often causes poor adaptability of equipment, different construction requirements are difficult to meet, and the wide width of the guide roller cannot be regulated, so that the guide roller is difficult to accurately fit a curb or a complex boundary, the edge area is insufficiently compacted, and the pavement flatness is influenced. Therefore, the inventor inherits the experience of the design development and the actual manufacturing in the related industry for many years, researches and improves the existing structure and the defects, and provides the practical wide-width adjusting device for the asphalt pavement pressure so as to achieve the purpose of having more practical value.
