Description

Technical Field

[0001] The utility model relates to the technical field of road construction equipment, in particular to a device for paving asphalt on a road surface of a road bridge. Background Art

[0002] Road bridges are structures specially built on roads to connect two locations. They are usually made of concrete, steel or other suitable materials and are designed to support traffic loads, including cars, pedestrians and possible heavy freight vehicles. Pavement asphalt is one of the commonly used materials in road construction and is usually used for the surface layer of roads. Its main components are asphalt and mineral aggregates. The main function of pavement asphalt on the road is to provide a flat, durable and anti-skid driving surface. It can withstand the weight of vehicles, reduce water damage, reduce the generation of dust and mud, and provide good driving comfort.

[0003] When paving asphalt on existing roads, asphalt is mostly poured on the road surface to be paved, and then the piles of asphalt are leveled manually, and finally the asphalt is compacted by a roller. However, during manual paving, manual operations are affected by technical level and experience, and it is difficult to ensure the consistency of the entire road surface, which makes the asphalt prone to gaps, waves and unevenness.

[0029] By adopting the above solution, the baffles 21 on both sides of the bottom end of the mounting frame 2 can effectively limit the lateral diffusion of the asphalt during paving, thereby ensuring the thickness consistency of the asphalt during paving.

[0030] The working principle of the utility model is as follows: when in use, asphalt is first poured into the storage hopper 4, and then the tractor 1 drives the device to move on the road surface where asphalt needs to be paved, and the motor 44 is started to rotate the rotating rod 42, driving the discharging plate 43 to rotate, so that the asphalt in the storage hopper 4 is evenly discharged from the discharging trough 41, and as the device moves, the V-shaped scraper 32 contacts the asphalt discharged from the storage hopper 4, and evenly scrapes the asphalt on the road surface, and cooperates with the baffles 21 on both sides of the bottom end of the mounting frame 2 to limit the two sides of the paved asphalt, ensuring the consistency of the thickness of the asphalt when it is paved, and finally the asphalt is compacted by the rolling pressing wheel 6; the V-shaped fixed frame 31 and the V-shaped scraper 32 can ensure that the asphalt is smooth during the paving process The V-shaped scraper 32 is automatically and evenly scraped on the road surface, which helps to ensure the flatness and consistency of the asphalt on the road surface. The V-shaped scraper 32 is firmly fixed in the V-shaped fixing frame 31 by the fixing bolts 33 to prevent loosening or failure during use. The height of the V-shaped scraper 32 can be adjusted by the fixing bolts 33, so that the thickness of the asphalt paving can be changed as needed. Through the rotation of the rotating rod 42 and the discharge plate 43, the asphalt can be accurately controlled and distributed on the road surface to be paved, thereby improving the accuracy and efficiency of the paving process. The baffles 21 on both sides of the bottom end of the mounting frame 2 can effectively limit the lateral diffusion of the asphalt during paving, thereby ensuring the thickness consistency of the asphalt when it is paved.
