Description

Technical Field

[0001] The present application belongs to the technical field of asphalt road construction, and specifically relates to a novel asphalt pavement leveling device and construction method. Background Art

[0002] Asphalt pavement refers to various types of pavement paved by adding asphalt materials to mineral materials. The asphalt binder can enhance the resistance of paving aggregate to traffic loads and natural environmental factors, making the road surface smoother, less dusty, impermeable and more durable. During the construction process, after the asphalt mixture is laid, compaction and leveling operations are usually required to ensure the flatness of the road surface.

[0003] At present, during the use of asphalt pavement leveling devices in the existing technology, some asphalt is easily adhered to the outer surface of the roller when some existing equipment is leveling the asphalt, which may affect the subsequent pavement leveling process. Therefore, it is necessary to regularly use a shovel to remove the sticky debris on the roller, resulting in low leveling efficiency and reducing construction efficiency to a certain extent. In addition, some existing equipment does not have the function of assisting the asphalt pavement to quickly cool and solidify. Therefore, there is an urgent need for an asphalt pavement leveling device and construction method to solve the above problems. Summary of the Invention

[0004] The present application provides a novel asphalt pavement leveling device and construction method, which effectively solves the problems of low leveling efficiency of existing asphalt pavement leveling devices due to the sticking of debris on the roller and the lack of rapid cooling and solidification function.

[0005] In order to achieve the above application objectives, this application provides the following technical solutions:

[0006] The present application provides a novel asphalt pavement leveling device, which is characterized by comprising a main structure and a leveling structure.

[0007] The main structure includes a support base, a fan, a dust screen and a fixed block. The fan is installed on the upper surface of the support base, and the four corners of the lower surface of the support base are fixedly connected to movable wheels. The lower surface of the support base is fixedly connected with an exhaust port, and the exhaust port is communicated with the air outlet of the fan. The dust screen is hingedly connected on the outer surface of the air inlet of the fan, and the fixed block is movably arranged on the outer surface of one side of the fan to fix the dust screen. The setting of the dust screen can play a certain dust-proof role on the interior of the fan, and can prevent external impurities from entering the interior of the fan, which can effectively improve the stability of the fan during operation. The fan can be provided with a power source through an external power supply. After the fan is started, it can draw external air and then blow it out through the exhaust port, thereby increasing the heat dissipation speed of the asphalt at the lower end of the exhaust port.

[0008] The two wheels are fixed together by a spring, and the two ends of the second end of the second end are fixed together by a spring, and the two wheels are connected with each other through the spring, and the two wheels are connected with each other through the spring. Rotating the tightening screw can push the pressure plate and the scraper to move downward, and at the same time push the two sets of second springs to contract. The setting of the two sets of connecting rods can limit the trajectory of the pressure plate during movement, thereby improving the stability of the pressure plate during movement.

[0009] Furthermore, an armrest is fixedly connected to one end of the upper surface of the support seat to facilitate pushing the leveling device for operation.

[0010] Furthermore, the fan is installed at a middle position between the upper surface of the support base.

[0011] Furthermore, a connecting block is fixedly connected to the outer surface of one side of the fan, and the outer end of the connecting block is fixedly connected to a connecting seat. An inner cavity is provided on one side surface of the connecting seat and a pull plate is inserted therein, and one end of the pull plate is fixedly connected to the fixing block. One side surface of the fixing block is attached to the outer surface of the dustproof net, and the other end of the fixing block is attached to a first spring, and the other end of the first spring is against the inner surface of the connecting seat. When one side surface of the fixing block is attached to one side surface of the dustproof net, the dustproof net can be fixed, and pulling the pull plate can drive the fixing block to separate from one side surface of the dustproof net. At this time, the dustproof net can be pulled to open it, so that the inside of the dustproof net can be cleaned.

[0012] Furthermore, a wrench is provided at the top end of the tightening screw to facilitate the rotation of the tightening screw.

[0013] The above technical solution describes a construction method for a new type of asphalt pavement leveling device. When the leveling device is used, first rotate the tightening screw to push the pressure plate and scraper downward, then adjust the scraper to a suitable position, and then start the fan to extract external air, and then blow it out through the exhaust port, and then push the equipment to use the pressure roller to flatten the asphalt pavement. Then the scraper can scrape off the asphalt attached to the outer surface of the pressure roller, and then the wind blown out of the exhaust port can accelerate the air flow rate on the surface of the asphalt pavement, thereby accelerating the heat dissipation speed of the asphalt pavement.

[0014] Compared with the existing technology, the present application discloses a novel asphalt pavement leveling device and construction method with the following advantages: the present application can provide a power source for the fan through an external power supply. After the fan is started, it can draw in external air and then blow it out through the exhaust port, thereby increasing the heat dissipation rate of the asphalt at the lower end of the exhaust port. This design can assist the asphalt pavement in rapid cooling and solidification, thereby improving the efficiency during construction to a certain extent. The present application can push the pressure plate and the scraper downward by rotating the tightening screw. At this time, the distance between the scraper and the pressure roller can be adjusted. When the pressure roller rolls, some asphalt will adhere to the outer surface. At this time, the scraper can scrape off the asphalt adhered to the outer surface of the pressure roller. This design can eliminate the process of manually scraping off the asphalt, thereby effectively improving the construction efficiency during asphalt paving. Moreover, its overall structural design is simple and reasonable, highly practical, and easy to promote and apply. BRIEF DESCRIPTION OF THE DRAWINGS
