Description

Technical Field

[0001] The utility model relates to the technical field of highway construction devices, in particular to an asphalt paving device for highway construction. Background Art

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is in liquid, semi-solid or solid state. It is an organic cementitious material that is waterproof, moisture-proof and corrosion-resistant. Its driving comfort, safety and strength stability are greatly improved. Compared with cement concrete pavement, asphalt pavement has a smooth and seamless surface, low driving vibration and noise, fast construction, short construction period, fast opening to traffic, and simple maintenance. It is an important structural form of road surface in my country.

[0003] In the prior art, when paving asphalt during highway construction, the asphalt needs to be spread by an asphalt truck first. After the spreading is completed, a roller truck is used to roll the asphalt over a large area. This can ensure the flatness of the ground and the density of the asphalt, thereby ensuring the durability of the road surface.

[0004] However, when rolling asphalt, rollers usually roll the middle part of the road. Due to the large size of the roller, it is easily affected by obstacles at the edge of the road and it is difficult to roll to the edge of the road. Manual re-rolling is required, which is more laborious. Utility Model Content

[0005] The purpose of the utility model is to provide an asphalt paving device for highway construction to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an asphalt paving device for highway construction, comprising: a roller body, an electric push rod installed at an edge of one end of the roller body, an output end of the electric push rod connected to a bearing plate, and an edge pressing roller installed at the bottom end of the bearing plate;

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model can adjust the position of the bearing plate through the electric push rod at one end of the roller body, so that the edge pressure roller is away from or close to the asphalt ground. The asphalt on the edge part of the road can be scraped flat by the scraper on one side of the edge pressure roller. The hard contact between the scraper and the fixed plate can be reduced by the elastic pad between the scraper and the fixed plate. The moving column at the top of the scraper and the elastic action of the buffer spring can further reduce the hard collision suffered by the scraper, making it less likely to be damaged. The bearing plate is driven to move by the roller body, which makes it convenient to roll the asphalt on the edge part of the road through the edge pressure roller, solving the problem that the roller is large in size and easily affected by obstacles at the edge of the road, and it is difficult to roll the part at the edge of the road. There is no need for manual re-rolling, which is more labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

The rotating shafts at both ends of the edge pressing roller 6 are rotatably mounted on the inner walls of the fixing frame 7 on both sides.

[0027] A splash guard 8 is mounted on one side of the edge roller 6, and a scraper 9 is mounted on the other side of the edge roller 6. A fixed plate 12 is connected to the top of the scraper 9, and an elastic pad 10 is fixedly mounted between the scraper 9 and the fixed plate 12. A mounting plate 17 is mounted on the top of the fixed plate 12, and mounting bolts 18 are mounted on the surface of the mounting plate 17. The splash guard 8 is tilted and fixedly mounted on the bottom end of the supporting plate 5 to prevent asphalt blocks adhering to the edge roller 6 from splashing around when the edge roller 6 is performing rolling work. The mounting plate 17 is T-shaped, with the bottom end of the mounting plate 17 fixedly connected to the fixed plate 12. A number of mounting bolts 18 are evenly arranged, and the top end of the mounting plate 17 is fixedly mounted to the bottom end of the supporting plate 5 via each mounting bolt 18, thereby facilitating the disassembly and assembly of the scraper 9.
