Description

Technical Field

[0001] This invention belongs to the field of road paving technology, specifically referring to a sidewalk foundation paving and leveling device. Background Technology

[0002] The construction of sidewalks requires laying concrete and other related materials on the roadbed, and then spreading and leveling them.

[0003] In existing technologies, road paving and leveling usually rely on vibratory levelers. The main principle of vibratory levelers is to use the vibration generated by the vibratory pump to spread materials such as concrete evenly.

[0004] Currently, vibratory levelers are highly efficient when vibrating relatively smooth concrete layers. However, when the concrete surface is uneven, the vibratory leveler needs to stay in that area for a longer period of time to properly level the road surface, which reduces its efficiency.

[0005] To address these issues, this invention proposes a sidewalk foundation paving and leveling device. Summary of the Invention

[0006] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a sidewalk foundation paving and leveling device. To solve the problem that when the concrete surface is uneven, the vibratory leveler needs to remain in that area for a long time to achieve proper leveling, thus reducing work efficiency, this invention proposes a paving area adjustment mechanism. This mechanism involves a positioning and moving scraper, both V-shaped and arranged in parallel rows between the anti-settlement plate and the vibratory plate. The positioning and moving scrapers are staggered and have multiple evenly distributed grooves on their surface.

[0017] The beneficial effects achieved by the present invention using the above structure are as follows: The present invention provides a sidewalk foundation paving and leveling device and its method of use, achieving the following beneficial effects:

[0018] (1) In order to solve the problem that when the concrete layer surface is uneven, the vibratory leveler needs to stay at that place for a long time to properly vibrate the road surface, which leads to a decrease in work efficiency, the present invention proposes a paving area adjustment mechanism. By setting a positioning opening and closing scraper and a moving opening and closing scraper between the anti-settlement plate and the vibratory plate, when the scraper moves to the uneven part of the concrete layer, the positioning opening and closing scraper and the moving opening and closing scraper can work together to scrape and pave the concrete protruding from the road surface.

[0019] (2) Through the paving area adjustment mechanism, the concrete protruding from the road surface can be laid evenly after passing through the equal distribution channel, thereby ensuring that the concrete layer surface in contact with the vibrating plate is relatively flat, making it easier to level the road surface.

[0020] (3) By adjusting the paving area, the scraping range of the concrete layer can be increased, making it more applicable when constructing sidewalks of different widths.

[0021] (4) The vibration-assisted leveling mechanism proposed in this invention only needs to further level and compact the concrete layer by vibrating the vibrating plate, without having to stay for a long time, thereby improving work efficiency.

[0022] (5) By setting adjustment components, the sliding speeds of multiple sliding blocks are different, so that the sliding blocks drive the scraper to move and unfold when they slide.

[0023] (6) The secondary paving auxiliary components are set so that the shaping scraper and the vibrating plate are slidably connected, and the adjusting spring provides thrust to ensure that the two shaping scrapers can be symmetrically distributed with the center of the vibrating plate as the central axis.

The pitch of the coarse thread section 53 is three times the pitch of the fine thread section 52.

[0046] In practical use, when the positioning and opening scraper 19, the movable opening and closing scraper one 22, the movable opening and closing scraper two 54, and the shaping scraper 36 move on the surface of the concrete layer, the lower ends of the positioning and opening scraper 19, the movable opening and closing scraper one 22, and the movable opening and closing scraper two 54 perform an initial scraping of the concrete protruding from the road surface, allowing excess concrete to accumulate on the sides of the positioning and opening scraper 19, the movable opening and closing scraper one 22, and the movable opening and closing scraper two 54. Then, the shaping scraper 36 performs a secondary scraping of the accumulated concrete, spreading out this portion of concrete. The concrete passes through the evenly distributed through groove 37 on the side of the shaping scraper 36, evenly spreading it on the surface of the concrete layer, improving the flatness of the concrete surface. When the vibrating pump 45 is working, it drives... The vibrating plate 44 vibrates and levels the concrete layer beneath it. Since the concrete layer in contact with the vibrating plate 44 has already been paved by the positioning and opening scraper 19, the moving opening and closing scraper one 22, the moving opening and closing scraper two 54, and the shaping scraper 36, the surface of the concrete layer is relatively smooth. The vibration of the vibrating plate 44 only requires further leveling and compaction of the concrete layer, without the need for prolonged pausing, thus improving work efficiency. The shaping scraper 36 is slidably connected to the vibrating plate 44, and the adjusting spring 41 provides thrust, ensuring that the two shaping scrapers 36 are symmetrically distributed about the center axis of the vibrating plate 44. Because the shaping scraper 36 is movably connected to the vibrating plate 44, the shaping scraper 36... The scraper 36 is less affected by the vibration of the vibrating plate 44. When the adjusting shaft 50 rotates, the sliding block 20 and the sliding block 26 can slide along the axial direction of the adjusting shaft 50, thereby driving the positioning opening and closing scraper 19, the moving opening and closing scraper 24 and the moving opening and closing scraper 22 to slide, and adjusting the angle of the two adjacent positioning opening and closing scrapers 19. Because the thread pitch of the fine thread section 52 and the coarse thread section 53 is different, the sliding speed between the sliding block 26 and the sliding block 30 is different. The positioning opening and closing scraper 19 located in the middle of the adjusting shaft 50 moves synchronously away from each other, and the moving opening and closing scraper 22 and the moving opening and closing scraper 24 located at both ends of the adjusting shaft 50 move synchronously away from each other, and the moving... The first opening and closing scraper 22 and the second moving opening and closing scraper 54 are both moving and unfolding at the same angle as the positioning opening and closing scraper 19 located in the middle of the adjusting shaft 50. That is to say, by rotating the adjusting shaft 50, the distance between the first moving opening and closing scraper 22, the second moving opening and closing scraper 54 and the positioning opening and closing scraper 19 can be adjusted. At the same time, the first moving opening and closing scraper 22 and the second moving opening and closing scraper 54 are unfolded, and the two positioning opening and closing scrapers 19 are unfolded at the same angle, which can increase the scraping range of the concrete layer by the device. It has better applicability when constructing sidewalks of different widths. The above is the overall working process of the present invention. This step can be repeated for the next use.
