[0025] Embodiment

[0026] As Figs. 1-2 shown, a cement smoothing device for road construction includes two support seats, a scraping device and two ropes 6, the scraping device is movably arranged between the two support seats through the ropes 6, the support seat includes a lifting platform, a winch 4 and a plurality of universal wheels 18, the universal wheels 18 are fixedly arranged at the bottom of the lifting platform, the winch 4 is fixedly arranged at the top of the lifting platform, the two ends of the rope 6 are wound on the winch 4 of the two side support seats respectively, the scraping device includes a moving box 7, two groups of scraping assemblies and a vibration assembly, a first inverted U-shaped plate 9 is arranged below the moving box 7 through a connecting rod 8, the two groups of scraping assemblies are rotatably arranged at the left and right ends of the first U-shaped plate 9 through a first rotating shaft 11, the vibration assembly is arranged on the first U-shaped plate 9 and located between the two groups of scraping assemblies, a through hole is arranged on the moving box 7 for the rope 6 to pass through, and the rope 6 is fixedly connected with the moving box 7 through the through hole.

[0027] It is worth mentioning that the support seat is provided to support the screeding device, the rope 6 is provided to provide a support point and a moving path for the screeding device, and the screeding device is provided to screed the cement ground. Specifically, the two ends of the rope 6 are wound on the two winches 4, and the two winches 4 can tighten and straighten the rope 6. After the rope 6 is tightened and straightened, one winch 4 winds the rope, and the other winch 4 unwinds the rope. The two winches 4 work synchronously to enable the moving box 7 fixed on the rope 4 to move relative to the road. The moving box 7 drives the screeding assembly and the vibration assembly to move on the cement ground to vibrate and screed the newly-paved cement. The vibration assembly vibrates the cement slurry to remove air bubbles in the cement slurry, so that the cement slurry is evenly distributed on the road to be paved, and the compactness of the cement ground is improved. The principle of the existing concrete vibrator is the same, and the screeding assembly is provided to screed the surface of the cement to improve the surface flatness of the cement road.

[0028] The winch 4 herein is an existing JK15 electric winch 4, and the specific structure and working principle thereof will not be described in detail in this embodiment.

[0029] In particular, the two groups of screeding assemblies are arranged on both sides of the vibration assembly, so that the screeding device can achieve the effect of screeding when moving left or right, without turning the screeding device, thereby reducing the work content of the workers.

[0030] In some possible embodiments, the lifting platform includes a base, a hydraulic cylinder 2, and a support plate 3. The hydraulic cylinder 2 is fixedly arranged at the bottom of the base, and the support plate 3 is fixedly arranged at the top of the telescopic end of the hydraulic cylinder 2. The rope 6 of the hydraulic cylinder 2 can adjust the ground clearance of the support plate 3, thereby adjusting the height of the winch 4, and then adjusting the ground clearance of the screeding device through the rope 6, so that the device can adapt to the cement screeding work in different environments. For the case that the heights of the two sides are inconsistent, the heights of the lifting platforms on the two sides can also be adjusted to make the winches 4 on the two sides at the same horizontal height, so as to avoid the inclination of the rope 6 leading to the non-standard levelness of the screeded cement ground.

[0031] In some possible embodiments, two limiting pieces 5 are arranged side by side on the support plate 3, and a through hole is formed in the limiting piece 5 for the rope 6 to pass through. The limiting piece 5 can fix the rope outlet position of the winch 4, and at the same time ensure that the distance between the two ropes 6 is consistent, so as to ensure the stable movement of the screeding device.

[0032] In some possible embodiments, the screeding assembly comprises a second U-shaped plate 10 and a scraper 12, the vertical sections on both sides of the second U-shaped plate 10 are rotatably arranged on the vertical sections on both sides of the first U-shaped plate 9 through the first rotating shaft 11, and the scraper 12 is fixedly arranged at the bottom of the second U-shaped plate 10 and has a downward convex arc structure. The second U-shaped plate 10 can rotate relative to the first U-shaped plate 9, and the second U-shaped plate 10 drives the scraper 12 to rotate together. When the screeding device moves with the moving box 7, the scraper 12 can automatically adjust to a suitable screeding angle.

[0033] In some possible embodiments, the bottom of the second U-shaped plate 10 is spaced apart from the bottom of the first U-shaped plate 9. When the side edge of the second U-shaped plate 10 contacts the bottom of the first U-shaped plate 9 after the second U-shaped plate 10 rotates by a certain angle, the second U-shaped plate 10 cannot continue to rotate, so the rotation angle of the second U-shaped plate 10 is limited, and the situation that the second U-shaped plate 10 cannot perform screeding work due to an excessively large rotation angle does not occur.

[0034] In some possible embodiments, the vibration assembly comprises two shock absorbers 14, a vibration plate 15, a vibration exciter 16 and a plurality of vibration rods 17. The top of each shock absorber 14 is fixedly arranged on the side of the first U-shaped plate 9 through the mounting plate 13, the top of the vibration plate 15 is fixedly connected with the bottom of the shock absorber 14, the vibration exciter 16 is fixedly arranged at the top of the vibration plate 15, and the plurality of vibration rods 17 are fixedly arranged at the bottom of the vibration plate 15. The vibration exciter 16 can drive the vibration plate 15 to vibrate, and then drive the plurality of vibration rods 17 to vibrate, so as to ensure that the cement can be uniformly filled into each corner of the road, and also can discharge the air bubbles in the cement slurry, and improve the compactness of the cement ground.

[0035] In use, the two support seats are placed on both sides of the road to be paved with cement, the winch 4 is started, the winch 4 works to tighten the rope 6, after the rope 6 is tightened, one side of the winch 4 is controlled to release the rope, the other side of the winch 4 is controlled to release the rope, the two winches 4 work synchronously, drive the moving box 7 fixedly arranged on the rope 4 to move relative to the road, and then the vibration exciter 16 is started, the vibration exciter 16 works to make the vibration rod 17 vibrate. Under the action of vibration, the cement slurry will be subjected to force, so as to be rearranged to reduce the air gap and air bubbles in the cement slurry, and ensure that the cement slurry can be uniformly distributed on the road. After a region is screeded, the support seat is moved to screed more regions of the cement slurry.

[0036] Specifically, since the support seat itself has a certain height, in use, the support seat needs to be placed lower than the paving height of the cement slurry, and it is ensured that the scraper 12 at the bottom of the screeding device can contact the surface of the cement slurry.

[0037] Furthermore, it should be understood that although the specification is described in terms of embodiments, not every embodiment includes every feature described. The specification can include implicit internal combinations of features that are not explicitly disclosed. Each embodiment depends on all of the features in combination, and no single feature is inherently implied by a particular embodiment. The specification is directed to all such combinations. The specification is also directed to every combination and permutation of the individual aspects described, as well as every combination and permutation of the individual aspects described in the dependent claims.
