Description

Technical Field

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

[0002] Currently, the most common method for road construction is to pour concrete. After grouting, the entire road surface is slurry-like, rough, and uneven. It is necessary to scrape the poured concrete to make it smooth. The common method is for construction workers to rely on experience and line of sight and use wooden boards to slowly scrape the surface. However, in large-scale construction, manually scraping the concrete with wooden boards cannot meet the work requirements. Not only is the labor cost high and the work efficiency low, but it is also impossible to obtain a good smooth surface. Utility Model Content

[0037] See Figures 1-3A concrete pavement construction leveling device includes two moving devices connected by a guide rail 1. A sliding mechanism is slidably connected to the guide rail 1, and a height adjustment mechanism is connected to the bottom of the sliding mechanism. A scraper 2 is connected to the bottom of the height adjustment mechanism.

[0038] In use, the two mobile devices are located on the hard surface of the road on both sides. The position of the height adjustment mechanism can be adjusted by moving the sliding mechanism on the guide rail 1 so that the scraper 2 is directly above the concrete surface that needs to be leveled. By adjusting the height of the height adjustment mechanism, the scraper 2 can contact the concrete surface that needs to be leveled. After adjustment, the two mobile devices are pushed to move the scraper 2 on the slurry surface to perform the leveling operation. In large-area construction situations, the work efficiency is higher and the labor intensity of the workers is reduced.

[0039] Furthermore, the mobile device includes: two support bases 3, each with a trapezoidal structure and four casters 4 connected to its bottom; two fixing sleeves 5 connected to the top of each support base 3, each fixing sleeve 5 having a tubular structure and its sidewalls welded to the top of the support base 3; and a first threaded hole 6 on the sidewall of each fixing sleeve 5; two guide rails 1, each of which can be a cylindrical rod, are provided; a sliding mechanism is slidably connected between the two guide rails 1, making the sliding mechanism more stable during movement; the two ends of the guide rails 1 are respectively located in the corresponding fixing sleeves 5 on the top of the two support bases 3, and then a first bolt 7 is threaded into the first threaded hole 6 to fix the two ends of the guide rails 1; the support bases 3 and the guide rails 1 are configured as a detachable connection structure for easy storage and transfer.

[0040] Alternatively, guide rails of different lengths can be selected according to the width of the concrete pavement to be leveled, thereby increasing the range of applications.

[0041] Furthermore, the sliding mechanism includes: four sliding sleeves 8, each sliding sleeve 8 having a tubular structure, with two sliding sleeves 8 fitted on each guide rail 1, and the side walls of the four sliding sleeves 8 being connected as a whole by a connecting plate 9, each sliding sleeve 8 having a second threaded hole 10 on its side wall, and a height adjustment mechanism connected to the bottom of the connecting plate 9.

[0042] In use, the guide rail 1 is passed through the sliding sleeve 8, and after adjusting the position, the second bolt 11 is threaded into the second threaded hole 10 to fix the guide rail 1 and the sliding sleeve 8. Then, the two ends of the guide rail 1 are passed through the fixing sleeve 5 and fixed. Then, the flattening work is carried out. The guide rail 1 and the sliding mechanism are set as a detachable connection structure for easy storage and transfer.

[0043] Furthermore, the height adjustment mechanism includes: an upper support plate 12, a lower support plate 13, and two threaded sleeves 14. Two first connecting rods 15 are hinged to the left and right sides of the upper support plate 12, and two first connecting rods 10 are hinged to the left and right sides of the lower support plate 13. The two threaded sleeves 14 are located between the upper support plate 12 and the lower support plate 13, and are also located on opposite sides of the upper support plate 12 and the lower support plate 13. The four first connecting rods 15 of the upper support plate 12 are grouped in pairs (front and rear) and connected to the two threaded sleeves 10 respectively. The left and right side walls of the 4 are hinged. The four first connecting rods 15 of the lower support plate 13 are respectively grouped into two front and two rear ones, and are respectively hinged to the left and right side walls of the two threaded sleeves 14. The adjusting screw 16 is threadedly connected to the two threaded sleeves 14. The surface of the adjusting screw 16 is provided with two opposite threads. The two threaded sleeves 14 are respectively threadedly connected to the two opposite threads of the adjusting screw 16. The connecting plate 9 and the upper support plate 12 are threadedly connected by the second connecting rod 21, and can be fixed by connecting bolts at the end of the second connecting rod 21.

[0044] In use, by rotating the adjusting screw 16, the two threaded sleeves 9 move inward at the same time, causing the lower support plate 13 to move downward until the scraper 2 contacts the concrete pavement. When the scraper 2 needs to move upward, the adjusting screw 16 can be rotated in the opposite direction, causing the two threaded sleeves 9 to move outward at the same time, thus lifting the scraper 2 upward.

[0045] Furthermore, one end of the adjusting screw 16 is connected to a rotating handle 17, and the end of the adjusting screw 16 with the rotating handle 17 has a certain length and is close to one of the support seats 3, so that during the leveling process, the operator can rotate the adjusting screw 16 by rotating the handle 17 at any time, thereby adjusting the height of the scraper 2 at any time.

[0046] Furthermore, the bottom of the lower support plate 13 is provided with an installation groove 18, the top of the scraper 2 is located in the installation groove 18, and the side wall of the lower support plate 13 corresponding to the installation groove 18 is provided with a third threaded hole 19. The scraper 2 is fixed by a third bolt 20 connected to the internal thread of the third threaded hole 19, and the scraper 2 is set as a detachable connection mechanism. Different lengths of scraper 2 can be replaced according to the width of the concrete pavement, which increases the range of use and facilitates the storage and transfer of scraper 2.
