Efficient roadbed flattening device for highway engineering construction

Abstract

The invention relates to the technical field of highway engineering flattening devices, and discloses an efficient roadbed flattening device for highway engineering construction. The efficient roadbed flattening device comprises a pressing wheel fixing frame and a pressing wheel roller body, the left end and the right end of the pressing wheel roller body are connected to the left inner wall and the right inner wall of the pressing wheel fixing frame through rotating shafts correspondingly, holes are evenly formed in the outer side wall of the pressing wheel roller body in the circumferential direction, a rolling sliding block is arranged in each hole, a weight adjusting inner cylinder is arranged in the pressing wheel roller body, supports are fixedly connected to the top faces of the left end and the right end of the pressing wheel fixing frame, and air pumps are fixedly connected to the top faces of the left ends of the supports. The left side and the right side of the bottom end of the pressing wheel fixing frame are each provided with two supporting connecting rods, and the top face of each supporting connecting rod is provided with a hydraulic telescopic rod. The operation is easy, use is convenient, and a claw rolling effect can be achieved without carrying, disassembling and installing a claw roller. The working intensity of constructors is effectively reduced, and the construction efficiency of highway engineering is effectively improved.

Description

technical field [0001] The invention relates to the technical field of flattening devices for road engineering, in particular to a high-efficiency roadbed flattening device for road engineering construction. Background technique [0002] The road roller, also known as the soil compactor, is a kind of equipment for road construction. Road rollers belong to the category of road equipment in construction machinery. They are widely used in the filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can roll sandy, semi-cohesive and cohesive soils, Subgrade stabilized soil and asphalt concrete pavement layer. With the gravity of the machine itself, the road roller is suitable for various compaction operations, so that the rolled layer can be permanently deformed and compacted.

Problems solved by technology

[0003] When compacting cohesive soil, the road rollers in the prior art need to be equipped with a sheep foot roller for rolling, which can not only obtain high-density soil, but also crush the filling soil material containing unbreakable soil clods. However, the claw mill needs to be carried and installed on the roller of the road roller during use, and needs to be dismantled after use, so there are defects of inconvenient carrying and cumbersome operation, which not only increases the work intensity of the construction personnel but also affects Improve the construction efficiency of highway engineering
