Road roller for constructional engineering

Abstract

The invention discloses a road roller for constructional engineering. The road roller comprises a machine body, a driving cabin, a first pressing wheel, a second pressing wheel and a third pressing wheel, wherein the driving cabin is fixedly arranged above the machine body; a first bearing and a second bearing are respectively mounted on two sides of the first pressing wheel and the second pressing wheel; the first bearing and the second bearing are connected through a first connecting column; the first bearing is connected with one side of the machine body through a second connecting column;third bearings are mounted on two sides of the third pressing wheel; the third bearings are connected with the other side of the machine body through a third connecting column; a mounting bracket is arranged above the third pressing wheel; one side of the mounting bracket is fixedly connected with the side wall of the machine body; a bulldozing assembly is mounted on one side of the mounting bracket; a soil loosening assembly is mounted on the other side of the mounting bracket; and the bulldozing assembly and the soil loosening assembly are arranged on two sides of the third pressing wheel. The road roller disclosed by the invention is novel in structural design, can perform road rolling operation on a road surface, can perform bulldozing operation on a mound, and facilitates road rolling; and in addition, the soil loosening operation on the road surface can also be realized, and the compaction performance of the road surface is improved.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a road roller for construction engineering. Background technique [0002] As construction machinery, construction road rollers can roll sandy, semi-cohesive and cohesive soils, roadbed stabilized soils and asphalt concrete pavement layers, and are widely used in the filling and compaction of large-scale engineering projects such as roads, railways, airport runways, dams, and stadiums. Operation. At present, construction rollers can be divided into three types according to the principle of compaction: static rolling construction rollers, vibratory construction rollers, and impact construction rollers. Static construction rollers act on the ground with their own gravity to achieve compaction; vibratory construction rollers set the vibration source to act on the rollers to vibrate and compact the ground; impact construction rollers mainly use non-circular rollers Ro...

AI Technical Summary

Problems solved by technology

But these three types of construction rollers can no longer meet the increasing needs of people, their compaction effect is poor, and they consume a lot of energy, which will bring losses to users

[0003] Existing road rollers can realize road rolling treatment, but the existing road rollers have a single structure and function, and can only realize road rolling operations, resulting in low utilization rate and poor use effect. Therefore, it is necessary to improve
