Description

Technical Field

[0001] This utility model relates to the field of road engineering equipment technology, and in particular to a roadbed leveling device. Background Technology

[0002] With rapid economic development and continuous urbanization, the scale and number of roads and bridges are constantly increasing. Roadbed leveling is a crucial and fundamental step in road and bridge construction. Its core purpose is to create a solid and flat foundation for road and bridge structures. During construction, the soil of the roadbed is precisely treated to ensure that the roadbed surface meets the specified flatness and compaction standards, thereby ensuring that the road and bridge have sufficient load-bearing capacity and stability in subsequent use, meeting the needs of long-term vehicle traffic and bridge structural safety. However, traditional manual construction methods are difficult to meet the ever-increasing construction scale and stringent quality standards. Therefore, roadbed leveling equipment has become the key to promoting efficient and high-quality road and bridge construction.

[0003] Roadbed leveling equipment is a type of specialized machinery used in road and bridge construction to level the roadbed. During construction, it precisely processes the soil and stone materials of the roadbed, and through uniform spreading and leveling, creates a flat roadbed surface that meets design requirements. This lays a solid foundation for subsequent pavement laying, ensuring road surface flatness and driving comfort, and is an important guarantee for ensuring the quality and progress of road and bridge projects.

[0004] Existing roadbed leveling equipment includes a vehicle body, scrapers, and pressure rollers. The vehicle body moves via a transmission system, powering the scrapers and pressure rollers. The scrapers are hydraulically controlled to scrape away material and initially level the roadbed according to a set setting. Subsequently, the pressure rollers compact the material by gravity and vibration, making the material tightly packed and improving the strength and smoothness of the roadbed. However, the scrapers and pressure rollers are prone to wear due to long-term friction with the material. Furthermore, due to their installation location and structural characteristics, replacement and maintenance are inconvenient, increasing maintenance costs and downtime. Therefore, a new roadbed leveling equipment is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0032] See attached document Figure 1 Appendix Figure 3 and attached Figure 4This utility model provides an embodiment of a roadbed leveling device, including a vehicle body 1, which serves as the basic load-bearing structure of the entire device and provides a platform for the installation and operation of other components. A drive system 3 is installed on the front top of the vehicle body 1, providing the device with propulsion power and enabling it to move within the roadbed construction site to meet the operational needs of different areas. A fixed platform 4 is fixedly connected to the front outer wall of the drive system 3, serving to connect and support telescopic rods 5, ensuring the stable installation of the telescopic rods 5 and providing a basis for subsequent adjustment of the scraper 10 height. Two telescopic rods 5 are fixedly connected to the inner wall of the fixed platform 4, and the height of the mounting base 6 can be adjusted by the telescopic movement of the telescopic rods 5, thereby allowing for adjustments according to different construction needs. The working height of the scraper 10 needs to be flexibly adjusted to improve the applicability of the equipment. The bottom ends of both telescopic rods 5 are fixedly connected to the same mounting base 6. The top of the mounting base 6 has a mounting groove 7, which cooperates with the mounting plate 8 to achieve the positioning and installation of the mounting plate 8. The mounting plate 8 is fixedly connected to the inner wall of the mounting base 6. The mounting plate 8 is used to fix the scraper 10, enabling the scraper 10 to perform stable leveling operations. A screw 9 is threadedly connected to the top of the mounting plate 8, and the screw 9 securely connects the mounting plate 8 to the mounting base 6 through threaded connection, facilitating the disassembly and replacement of the scraper 10 when needed. The scraper 10 is fixedly connected to the bottom of the mounting plate 8. The scraper 10 is used to level the material on the roadbed surface, achieving a preliminary leveling state for the roadbed. The top of the vehicle body 1... A rear box 11 is provided at the rear of the equipment. The rear box 11 protects the internal components and provides an installation position for the roller seat 12, ensuring the integrity and stability of the internal structure. The roller seat 12 is fixedly connected to the rear outer wall of the rear box 11. The roller seat 12 is used to install the pressure roller assembly, providing stable support and a mounting foundation for the pressure roller assembly. The outer wall of the roller seat 12 has a groove 13, which cooperates with the pull rod 14. When disassembling the pressure roller assembly, it is convenient to slide the pull rod 14, enabling quick disassembly of the pressure roller assembly. The pressure roller assembly is located at the rear of the roller seat 12. The pressure roller assembly is used to compact the leveled roadbed, improving the density and smoothness of the roadbed. The pressure roller assembly includes the pull rod 14, which is slidably connected to the roller seat 12, allowing for easy disassembly. The roller assembly can be moved to facilitate operation during installation. Two rotating plates 15 are rotatably connected to the outer wall of the pull rod 14. The rotating plates 15 connect the pull rod 14 to the roller shaft 16 and can rotate around the roller shaft 16 when disassembling the roller assembly, so that the roller assembly can be smoothly separated from the roller seat 12. The same roller shaft 16 is rotatably connected to the adjacent side of the two rotating plates 15. The roller shaft 16 supports the circular roller 17 and allows it to rotate freely, ensuring the normal operation of the circular roller 17 during compaction. The circular roller 17 is rotatably connected to the outer wall of the roller shaft 16. The circular roller 17 compacts the roadbed surface during the movement of the equipment, making the roadbed more compact and flat. A cleaning mechanism 2 is provided on the rear side of the roller seat 12. The cleaning mechanism 2 is used to clean the mud on the roller assembly.

[0033] Specifically, the telescopic rod 5 and the fixed platform 4 work together to flexibly adjust the height of the scraper 10 according to construction needs, which makes it easier to scrape the roadbed material and make the roadbed initially flat. At the same time, it makes the scraper 10 easier to disassemble. The pull groove 13 on the roller seat 12 works with the pull rod 14 to realize the quick disassembly of the pressure roller assembly, which is convenient for subsequent maintenance. The pressure roller assembly compacts the roadbed after it is scraped, improving the density and flatness.

[0034] See attached document Figure 1 and attached Figure 5 The cleaning mechanism 2 includes an extension plate 201. The front side of the outer wall of the extension plate 201 is fixedly connected to the rear side of the outer wall of the roller seat 12. Through this connection, the extension plate 201 provides a stable installation base for the cleaning mechanism 2. A scraper 202 is rotatably connected to the rear side of the extension plate 201. When the equipment is working, the scraper 202 hangs down naturally and contacts the surface of the pressure roller, thereby effectively scraping off larger particles of debris attached to the surface of the pressure roller and reducing the difficulty of subsequent cleaning. Two locking blocks 203 are fixedly connected to the bottom of the extension plate 201, and a brush plate 204 is slidably connected to the bottom of the extension plate 201. The brush plate 204 can slide along the bottom of the extension plate 201, facilitating installation and disassembly operations. The top of the brush plate 204 has two slots 205, which engage with the locking block 203 to enable the brush plate 204 to be quickly and accurately positioned during installation. The bottom of the brush plate 204 is fixedly connected to a brush 206. When the pressure roller rotates, the brush 206 contacts the surface of the pressure roller to further clean the small debris left after the scraper 202 removes it, thus improving the cleaning effect. The left and right sides of the outer wall of the extension plate 201 are rotatably connected to locking plates 207. After the brush plate 204 is installed in place, the locking plates 207 are rotated to cover the brush plate 204, preventing the brush plate 204 from shifting during operation and ensuring that the brush 206 can continuously and stably clean the pressure roller.

[0035] Specifically, the scraper 202 is rotatably connected to the extension plate 201, allowing it to hang naturally and fit against the pressure roller, effectively scraping away larger particles of debris and reducing the burden of subsequent cleaning. The cooperation between the locking block 203 and the slot 205 makes the brush plate 204 easy to install and remove, and also allows for precise positioning. The brush 206 is fixed to the bottom of the brush plate 204, deeply cleaning the small debris remaining after the scraper 202 has cleaned, significantly improving the cleaning effect. After the brush plate 204 is installed, the locking plate 207 rotates to cover it, preventing it from shifting during operation and ensuring that the brush 206 continuously and stably cleans the pressure roller, keeping the pressure roller in good working condition at all times, avoiding debris from affecting the compaction effect, thereby improving the quality of roadbed leveling construction.

[0036] See attached document Figure 1 Appendix Figure 2 and attached Figure 3The top left and right sides of the vehicle body 1 are equipped with steps 18, providing operators with a convenient structure for getting on and off the vehicle body 1 and facilitating personnel access to the equipment. Multiple anti-slip strips 19 are fixedly connected to the top of each step 18, increasing the friction between the foot and the step 18 and effectively preventing operators from slipping when getting on and off, ensuring personnel safety. A seat 20 is fixedly connected to the top of the vehicle body 1, providing operators with a comfortable seating position and reducing fatigue during long-term operation. An operating platform 21 is fixedly connected to the rear of the drive system 3. The operating platform 21 is used to centrally install various operating components, facilitating operator control of the equipment. Multiple buttons 22 are provided on the outer wall of the operating platform 21, which can be used to control various functions of the equipment. A steering wheel is located on the rear of the operating platform 21. 23 is used to control the direction of travel of the equipment, so that the equipment can move accurately within the construction site. The outer wall of the rear box 11 is provided with multiple heat dissipation holes 24. The heat dissipation holes 24 can help the components inside the rear box 11 dissipate heat and prevent the equipment from being affected by excessive temperature. The bottom of the vehicle body 1 is provided with multiple wheels 25. The wheels 25 support the vehicle body 1 and enable the equipment to move on the ground to meet the operation needs of different construction areas. The rear side of the scraper 10 is fixedly connected with a reinforcing plate 26. The reinforcing plate 26 enhances the structural strength of the scraper 10 and prevents the scraper 10 from deforming and being damaged due to force during operation. The outer wall of the mounting plate 8 is provided with multiple screw holes 27. The screw holes 27 cooperate with the screws 9 for fastening the mounting plate 8 and the mounting base 6, which facilitates the disassembly and replacement of the scraper 10.

[0037] Specifically, the steps 18 and anti-slip strips 19 facilitate safe entry and exit for personnel, ensuring the personal safety of operators. The seat 20 provides a comfortable operating environment, reducing operator fatigue and improving work efficiency. The control panel 21 integrates various operating components, along with buttons 22 and a steering wheel 23, allowing operators to easily control the various functions and direction of travel of the equipment, accurately completing construction tasks. The reinforcing plate 26 enhances the strength of the scraper 10, preventing deformation during operation and extending its service life.

[0038] Working Principle: The vehicle body 1 is the basic carrier of the entire equipment. The drive system 3 is located on the front top of the vehicle body 1, providing the equipment with the power to move. When it is necessary to adjust the working height of the scraper 10 or to perform maintenance, the extension and retraction of the telescopic rod 5 is controlled to raise or lower the mounting base 6, thereby creating operating space for disassembling the scraper 10. The scraper 10 is fixed to the mounting base 6 by engaging the mounting plate 8 with the mounting groove 7. The two are connected by screws 9. When it is necessary to disassemble the scraper 10, the operator only needs to use a tool to unscrew the screws 9, release the fixed connection between the mounting plate 8 and the mounting base 6, and then remove the mounting plate 8 along with the scraper 10 from the mounting base 6 for easy replacement or maintenance of the scraper 10. During installation, align the mounting plate 8 with the mounting groove 7 and tighten the screws 9 to complete the installation. A roller seat 12 is fixedly connected to the rear side of the outer wall of the rear box 11 on the rear top of the equipment. The wall has a groove 13, and the bottom of the groove 13 engages with the pull rod 14. When the equipment moves forward, the vehicle body 1 drives the rear box 11 and roller seat 12 to move forward, and the pressure roller assembly also moves forward. Since the roller shaft 16 of the circular roller 17 is connected to the pull rod 14 through the rotating plate 15 and the roller shaft 16 can rotate, the circular roller 17 rotates around the roller shaft 16 under the action of ground friction to compact the roadbed. When it is necessary to disassemble the pressure roller assembly, the equipment is driven to move backward. At this time, the circular roller 17 contacts the ground under its own weight and does not move. The roller seat 12 moves backward with the vehicle body 1, which causes the pull rod 14 to be squeezed and slide outward along the groove 13. At the same time, the movement of the pull rod 14 drives the rotating plate 15 to rotate around the roller shaft 16. The rotation of the rotating plate 15 causes the roller shaft 16 and the circular roller 17 to gradually separate from the rear side of the roller seat 12, thereby realizing the quick disassembly of the pressure roller assembly, which is convenient for subsequent cleaning and maintenance operations.

[0039] Furthermore, the front side of the outer wall of the extension plate 201 is fixed to the rear side of the outer wall of the roller seat 12, providing an installation base for the cleaning mechanism 2. The scraper 202 is rotatably connected to the rear side of the extension plate 201. When the equipment is working, the scraper 202 hangs down naturally and contacts the surface of the pressure roller. During the rotation of the pressure roller, the scraper 202 can scrape off larger particles of debris attached to the surface of the pressure roller, reducing the difficulty of subsequent cleaning. The two locking blocks 203 at the bottom of the extension plate 201 cooperate with the two locking slots 205 at the top of the brush plate 204. When it is necessary to install the brush plate 204, the brush plate 201 is... 4. Slide along the bottom of the extension plate 201 to engage the locking block 203 with the slot 205, thus initially fixing the brush plate 204. The brush 206 is fixed to the bottom of the brush plate 204. When the pressure roller rotates, the brush 206 contacts the surface of the pressure roller to further clean the small debris remaining after the scraper 202 removes it, improving the cleaning effect. After the brush plate 204 is installed in place, rotate the locking plate 207 to cover the brush plate 204, preventing the brush plate 204 from shifting during operation and ensuring that the brush 206 can continuously and stably clean the pressure roller. If it is necessary to replace the brush 206 or the brush plate 204, simply rotate the locking plate 207 in the opposite direction and slide the brush plate 204 out along the bottom of the extension plate 201 to complete the disassembly operation.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
