Abstract
Description
Technical Field
[0001] This utility model relates to the field of highway engineering technology, specifically to a device for leveling asphalt pavement on highways. Background Technology
[0002] Asphalt pavement is a variety of types of road surface formed by paving and compacting asphalt concrete. Asphalt concrete is a mixture made by thoroughly mixing asphalt material with a certain viscosity and appropriate amount with mineral aggregates of a certain gradation. As an asphalt pavement material, asphalt concrete must withstand the repeated loads of vehicles and the long-term effects of environmental factors during use. Therefore, while possessing a certain load-bearing capacity, asphalt concrete must also have good durability against the effects of natural factors. In other words, it must exhibit sufficient stability under high temperature conditions, crack resistance under low temperature conditions, good water stability, long-lasting anti-aging properties, and skid resistance that is conducive to safety, in order to ensure the good service function of asphalt pavement.
[0003] Currently, more and more roads and sites in urban and rural areas are being paved with asphalt concrete. In the current asphalt concrete road surface paving, large equipment is used for overall paving. However, for areas such as curbs and roadsides that large machinery cannot access, manual paving is required. However, manual paving tools are rudimentary, often resulting in unevenness in certain areas. In addition, manual paving is labor-intensive for workers and does not achieve a good level of smoothness, which is not conducive to improving work efficiency.
[0004] For example, the asphalt pavement leveling device for highway engineering disclosed in announcement number CN214497090U uses a shovel mechanism to initially level the asphalt, and then the leveling disc is made to vibrate and rotate continuously in close contact with the asphalt pavement to spread and compact the asphalt. The pavement can also be rolled multiple times by a pressure roller, which not only effectively improves the leveling quality, but also reduces the labor intensity of workers and improves work efficiency.
[0005] However, when the rollers compact the road surface, some asphalt adheres to the rollers, which affects the subsequent leveling quality of the road surface.
[0006] Therefore, we urgently need to provide a device for leveling asphalt pavements on highways. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0026] Based on current technology, during the compaction of the road surface using rollers, some asphalt adheres to the rollers, affecting the subsequent leveling quality of the road surface. Please refer to [link to relevant documentation]. Figures 1-4 This embodiment provides a road asphalt pavement leveling device that can scrape off asphalt adhering to the surface of the pressure roller, thereby improving the leveling quality of the road surface. The road asphalt pavement leveling device includes a support plate 1, a mounting plate 2, and a pressure roller 3. The support plate 1 is fixedly installed around its bottom perimeter. The pressure roller 3 is installed between two mounting plates 2. Auxiliary devices are provided at the top and bottom of the support plate 1, including a cleaning mechanism, a cooling mechanism, and a filling mechanism.
[0027] The cleaning mechanism is located below the support plate 1, the cooling mechanism is located at the bottom of the support plate 1, and the filling mechanism is located at the top of the support plate 1.
[0028] The cleaning mechanism includes a mounting rod 401, a ring 402, a connecting rod 403, a connecting plate 404, a damping rod 405, a spring 406, and a scraper 407. The mounting rod 401 is fixedly installed on the right side of the mounting plate 2, and the ring 402 is fixedly installed on the outside of the mounting rod 401. There are multiple rings 402 and connecting rods 403. The multiple rings 402 and connecting rods 403 improve the installation strength between the ring 402 and the mounting rod 401. One end of the connecting rod 403 is fixedly installed on the outside of the ring 402, and the connecting plate 404 is fixedly installed on the other end of the connecting rod 403. At one end, the damping rod 405 is fixedly installed on the right side of the connecting plate 404, and the spring 406 is installed on the outside of the damping rod 405. The spring 406 and the damping rod 405 work together to prevent the scraper 407 from being damaged due to excessive contact force between the scraper 407 and the pressure roller 3. The scraper 407 is fixedly installed on the right end of the damping rod 405. There are two cleaning mechanisms, which are installed on the left side of two adjacent mounting plates 2. The scraper 407 contacts the surface of the pressure roller 3 and scrapes off the asphalt adhering to the surface of the pressure roller 3, thereby improving the road leveling quality of the pressure roller 3. Example
[0029] Based on Example 1, please refer to Figures 1-4During the asphalt compaction process of roller 3, the surface temperature of roller 3 gradually increases. Excessive surface temperature can soften the asphalt pavement and damage it. Therefore, to improve the compaction quality, this device is equipped with a cooling mechanism. This mechanism includes a water tank 501, a pump body 502, a water outlet pipe 503, a connecting pipe 504, and a nozzle 505. The water tank 501 is mounted on the top of the support plate 1, the pump body 502 is mounted on the left side of the water tank 501, and one end of the water outlet pipe 503... The pump body 502 is connected to the output end, and the connecting pipe 504 is connected to the water outlet pipe 503. The other end of the pipe is located below the support plate 1. The nozzle 505 is connected to the bottom of the connecting pipe 504. There are multiple nozzles 505, and the multiple nozzles 505 are symmetrically distributed at the bottom of the connecting pipe 504. The nozzles 505 are used to treat the dust generated during road surface leveling. At the same time, the water mist sprayed from the nozzles 505 is sprayed onto the surface of the two pressure rollers 3 to cool down the pressure rollers 3 and prevent the road asphalt from softening due to excessive temperature of the pressure rollers 3. Example
[0030] Based on Example 1, please refer to Figures 1-4 When there are damaged sections of the road surface, it is necessary to repair the road surface at any time. Therefore, this device is equipped with a filling mechanism, which includes a material box 601, a discharge port 602, an auger feeder 603, a discharge pipe 604, and a valve 605. The material box 601 is installed on the top of the support plate 1, located to the right of the water tank 501. The material box 601 contains asphalt. The discharge port 602 is connected to the material box 601. By starting the auger feeder 603, the asphalt in the material box 601 is transported, and the asphalt flows out along the discharge pipe 604 to repair the broken road surface, thereby improving the smoothness of the road surface. The discharge port 602 is installed on the right side of the material box 601. The auger feeder 603 is installed inside the discharge port 602 and transports the asphalt through the auger feeder 603. The discharge pipe 604 is connected to the back of the discharge port 602, and the valve 605 is installed on the outer side of the lower end of the discharge pipe 604.
[0031] In use, the device is moved to the desired position, and then the support plate 1 is pushed to cooperate with the pressure roller 3 to flatten the asphalt pavement. At the same time, the asphalt adhering to the pressure roller 3 comes into contact with the scraper 407 as the pressure roller 3 rotates. The scraper 407 scrapes off the asphalt adhering to the pressure roller 3, improving the leveling quality of the road surface. The pump body 502 is started so that the water in the water tank 501 enters the connecting pipe 504 through the water outlet pipe 503 and is then sprayed onto the surface of the pressure roller 3 through the nozzle 505 to cool the pressure roller 3 and prevent the asphalt from softening due to excessive temperature, which would damage the road surface. At the same time, the water can reduce the dust generated during road leveling and reduce the pollution caused by dust to the environment. When there is damage to the road surface, the device is pushed so that the discharge pipe 604 is directly above the damaged area. Then the auger feeder 603 is started to transport the asphalt in the material box 601, so that the asphalt flows along the discharge pipe 604 to the damaged area to repair the road surface and improve the leveling quality of the road surface.
