Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a compacting device for road construction. Background Art

[0002] Road engineering refers to the entire process of planning, design, construction, maintenance and management with roads as the object and the engineering entities involved. During the construction of highway projects, compaction devices are often required to compact the construction road surface to ensure the tightness of the roadbed and the quality of the highway project.

[0003] According to Chinese patent application No. (202223445075.X), a compaction device for road engineering construction is proposed, which belongs to the field of road construction technology, including a base, and the side walls of the base are fixedly installed with a top plate through symmetrical brackets. When the road is compacted, the output shaft of the motor drives the half gear to rotate, and the compaction plate continuously compacts the road through the continuously rotating half gear, thereby improving the efficiency of the road surface compaction process. When the compacted road surface is small, the first connecting plate is moved so that the first connecting plate drives the clamping rod to move, and the first connecting plate is moved to a position where it is in contact with the two second connecting plates. At this time, the clamping rod is taken out of the groove cavity of the first support seat, and then the connecting bolt is screwed to connect the first connecting plate with the second connecting plate. The corresponding compaction plate is driven to move by the second movable column that moves back and forth alone, so that the construction process is adjusted according to the construction surface, thereby bringing convenience to the construction process of relevant personnel.

[0004] After improving the compaction device for road construction, this application uses a second movable column that moves back and forth independently to drive the corresponding compaction plate to move, so that the construction process can be adjusted according to the construction surface, thereby bringing convenience to the construction process of relevant personnel. However, the device cannot adjust the size of the compaction plate, and there is no shock-absorbing device during the operation of the machine. For this reason, we propose a compaction device for road construction. Utility Model Content
