Description

Technical Field

[0001] This utility model relates to the field of highway construction technology, specifically to a road surface leveling device for highway construction. Background Technology

[0002] Highways connect different cities, towns, and villages, enabling convenient and fast transportation of goods. For example, agricultural products can be transported from rural areas to urban farmers' markets or processing plants, and industrial products can be transported from factories to various sales points. During highway construction, both the roadbed and the pavement surface may have some degree of unevenness in their initial state. For example, after the roadbed is constructed, potholes and bumps may appear due to differences in soil compaction or local interference during construction. Leveling equipment uses methods such as scraping and rolling to make the road surface smoothness meet the design requirements. When vehicles drive on leveled roads, passengers can experience a smoother and more comfortable ride with reduced bumps and vibrations. However, with existing road leveling equipment, when the asphalt mixture is freshly laid during highway construction, its temperature is relatively high, generally around 130-170 degrees Celsius, at which point the asphalt is in a relatively viscous state. When a roller comes into contact with a high-temperature asphalt mixture, asphalt easily adheres to its surface. Often, when a large amount of asphalt adheres to the roller's surface, it results in an uneven surface. When the roller with asphalt rolls on the road surface, the uneven distribution of asphalt causes uneven contact pressure between the roller and the road surface, thus reducing the efficiency of road leveling. To address this, we propose a road leveling device for highway construction. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figure 1-4 This embodiment provides a technical solution: a road surface leveling device for highway construction, including a vehicle body 1, a control switch group 6 inside the vehicle body 1, the input end of the control switch group 6 being electrically connected to an external power source, an installation compartment 3 in the middle of the vehicle body 1, a leveling opening 31 on the lower side wall of the installation compartment 3, an adjustable road roller 9 inside the installation compartment 3, a turntable 8 rotatably connected between the left and right inner walls of the installation compartment 3 via a rotating shaft 10, road rollers 9 rotatably connected to both the upper and lower ends of the left side of the turntable 8, a motor 7 installed on the right side of the installation compartment 3, the output shaft of the motor 7 being fixedly connected to the center of the right side of the rotating shaft 10, the input end of the motor 7 being electrically connected to the output end of the control switch group 6, a protective shell 5 on the right side of the installation compartment 3, a storage compartment 4 on the left side wall of the installation compartment 3, the storage compartment 4 being connected to the installation compartment 3, a retrieval door 41 hinged to the left side wall of the storage compartment 4, and a cleaning mechanism 2.

[0022] Cleaning mechanism 2 includes sliding columns 21, mounting plates 23, and scrapers 25. Sliding columns 21 are symmetrically distributed between the left and right inner walls of the mounting chamber 3. Mounting plates 23 are slidably connected to the outer arc surfaces of the sliding columns 21. Adjustable scrapers 25 are provided on the upper sides of the mounting plates 23. The scrapers 25 are installed in conjunction with the rollers 9. Cleaning mechanism 2 also includes electric cylinders 24, which are respectively installed on the upper sides of the two mounting plates 23. The middle of each scraper 25 is fixedly connected to the telescopic end of the electric cylinder 24. The input terminals are all electrically connected to the output terminals of the control switch group 6. The cleaning mechanism 2 also includes lead screws 22 and synchronous pulleys 27. The lead screws 22 are symmetrically distributed and rotatably connected between the left and right inner walls of the mounting chamber 3. The lead screws 22 are all threadedly connected to the upper end of the adjacent mounting plate 23 on the lower side. The outer arc surface of the right end of the lead screw 22 is fixedly fitted with synchronous pulleys 27. The two synchronous pulleys 27 are connected by a synchronous belt 28. The cleaning mechanism 2 also includes a motor 29. The motor 29 is mounted on the right side of the mounting chamber 3 through a mounting bracket.The output shaft of the motor 29 passes through the middle of the mounting bracket and is fixedly connected to the center of the right end of the lead screw 22 on the rear side. The input end of the motor 29 is electrically connected to the output end of the control switch group 6. The cleaning mechanism 2 also includes a sliding plate 26, which is symmetrically distributed on the left side of the turntable 8 (the sliding plate 26 is tilted with the right side higher than the left). The worker works with the vehicle 1 to drive on the road section where the road surface needs to be leveled. During the driving process, the lower end of the roller 9, which is currently located on the lower side, passes through the leveling opening 31 and moves the roller on the road surface. The rollers are rolled to compact and level the road surface. During this process, asphalt on the road section will adhere to the surface of the rollers 9. To ensure the subsequent road leveling is up to standard, the adhered asphalt needs to be cleaned from the surface of the rollers 9. At this time, the worker operates the control switch group 6 to start the motor 7. The output shaft of the motor 7 drives the turntable 8 to rotate through the rotating shaft 10. In turn, the turntable 8 drives the two rollers 9 to rotate. At this time, the rollers 9 with asphalt adhered to their lower surface rotate to the upper side, and the rollers 9 without asphalt adhered to their lower side rotate to the lower side, and the leveling work continues. The worker operates the control switch assembly 6 to activate the two electric cylinders 24. The extension and retraction ends of the electric cylinders 24 push the two scrapers 25 towards the roller 9. At this time, the two scrapers 25 are in contact with the arc surface of the roller 9 (the scraper 25 is an arc-shaped scraper). Immediately afterwards, the worker operates the control switch assembly 6 to activate the motor 29. The output shaft of the motor 29 drives the lead screw 22 on the rear side to rotate. At this moment, the synchronous pulley 27 on the rear side also rotates synchronously. Then, under the transmission action of the synchronous belt 28, the synchronous pulley 27 on the front side drives the lead screw 22 on the front side to rotate synchronously. At this point, under the rotational constraint of the screw 22 thread and the sliding column 21, the two mounting plates 23 slide backward along the adjacent sliding column 21, thereby driving the electric cylinder 24 and scraper 25 to move synchronously, scraping off the asphalt adhering to the surface of the roller 9. The asphalt falls into the interior of the sliding plate 26 currently located on the upper side, slides down the sliding plate 26, and enters the interior of the storage chamber 4 through the connection between the mounting chamber 3 and the storage chamber 4. After a period of time, workers open the retrieval door 41 to collect it, facilitating the cleaning of the asphalt adhering to the surface of the roller 9.

[0023] The working principle of the road surface leveling equipment for highway construction provided by this utility model is as follows: A worker, in conjunction with the vehicle 1, travels along the road section requiring leveling. During travel, the lower end of the roller 9, currently positioned at the bottom, rolls across the road surface through the leveling opening 31, compacting and leveling the surface. During this process, asphalt from the road section adheres to the surface of the roller 9. To ensure the subsequent pass rate of road leveling, the adhered asphalt needs to be cleaned from the surface of the roller 9. At this time, the worker operates the control switch group 6 to activate the motor 7. The output shaft of the motor 7 drives the turntable 8 to rotate via the rotating shaft 10. The turntable 8 then drives the two rollers 9 to rotate. The roller 9 with asphalt adhering to its lower surface rotates to the upper side, while the roller 9 without asphalt adhering to its lower surface rotates to the lower side, continuing the leveling work. Subsequently, the worker operates the control switch group 6 to activate the two electric cylinders 24. The extension and retraction ends of the electric cylinders 24 move the two scrapers 2... 5. Push the roller 9 towards the roller. At this time, the two scrapers 25 are in contact with the arc surface of the roller 9 (the scraper 25 is an arc-shaped scraper). Then, operate the control switch group 6 to make the motor 29 run. The output shaft of the motor 29 drives the lead screw 22 on the rear side to rotate. At this time, the synchronous pulley 27 on the rear side also rotates synchronously. Then, under the transmission action of the synchronous belt 28, the synchronous pulley 27 on the front side drives the lead screw 22 on the front side to rotate synchronously. At this time, the two mounting plates 23 slide backward along the adjacent slide 21 under the rotation restriction of the screw 22 thread and the slide column 21. This drives the electric cylinder 24 and the scraper 25 to move synchronously, hanging down the asphalt adhering to the surface of the roller 9. The asphalt falls into the interior of the sliding plate 26 currently located on the upper side, slides down the sliding plate 26, and enters the interior of the storage chamber 4 through the connection between the mounting chamber 3 and the storage chamber 4. After a period of time, the worker opens the retrieval door 41 to collect it.

[0024] It is worth noting that the vehicle body 1 disclosed in the above embodiments is a conventional road leveling and rolling vehicle. The motor 7 can be model DM100040P2-90, the electric cylinder 24 can be model FY020, and the electric motor 29 can be model YVF2-200L1-2. The control switch group 6 is equipped with control buttons that correspond one-to-one with the motor 7, the electric cylinder 24 and the electric motor 29 and are used to control their switching.
