Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a roller type cement concrete pavement flattener. Background Art

[0002] During the road construction process, after the cement concrete is laid, rolling equipment is usually required to flatten the road surface. Generally, a flattening roller is used to level the road. The flattening roller acts on the surface of the cement concrete and rolls on its upper surface to flatten the cement concrete.

[0003] During the rolling contact process of the existing flattening roller with cement concrete, cement concrete is easily adhered to the roller surface. If it is not cleaned in time, the quality of the road surface flatness will be affected. At the same time, the concrete adhered to the roller surface for a long time will solidify on the roller surface and is difficult to handle, affecting the normal use of the roller in the later stage.

[0032] Reference Figure 1-4 The roller type cement concrete pavement flattener is used to flatten the cement concrete pavement during construction, in order to facilitate the cleaning of the cement concrete adhered to the surface of the roller.

[0033] The roller type cement concrete pavement flattener comprises a push rod 1, a roller 5, two connecting rods 2, two rotating rods 8 and a scraper 9;

[0034] Both ends of the push rod 1 are provided with rubber sleeves with anti-slip threads, which are convenient for holding the push rod 1, so as to push the road surface flattener to flatten the cement concrete road surface. At the same time, a mounting part 10 is provided on the push rod 1, and the road surface flattener is conveniently connected to the rolling equipment through the mounting part 10, so that the cement concrete road surface is rolled and flattened under the drive of the rolling equipment.

[0035] A coaxial support sleeve 12 is provided inside the roller 5, and a plurality of support rods 11 are fixedly connected between the support sleeve 12 and the roller 5. A fixed shaft 7 is fixedly connected between the two ends of the two connecting rods 2. The fixed shaft 7 passes through the support sleeve 12, and the other ends of the two connecting rods 2 are fixedly connected to the push rod 1. The connecting rod 2 is driven by the push rod 1, and the roller 5 can roll on the outside of the fixed shaft 7 through the support sleeve 12, so that the roller 5 can roll and level the cement concrete pavement.

[0036] The two connecting rods 2 are fixedly connected with a connecting plate 4 in the middle part, and one end of the two rotating rods 8 is rotatably connected to the two connecting plates 4 respectively, and the other end of the two rotating rods 9 is fixedly connected to the scraper 9. The two rotating rods 8 can drive the scraper 9 to move. Therefore, when it is necessary to clean the surface of the roller 5, it is only necessary to rotate the two rotating rods 9 downward, so that the scraper 9 moves to one side of the roller 5 and makes the top of the scraper 9 inclined upward fit with the outer wall of the roller 5. When the roller 5 is rolling and leveling the cement concrete pavement, the cement concrete adhered to the outside of the roller 5 will be scraped off by the scraper 9 and fall back to the cement concrete pavement along the inclined surface of the inclined upward scraper 9 and be flattened again by the roller 5. Therefore, after scraping off the cement concrete outside the roller 5, the scraper 9 will also make the cement concrete fall back to the cement concrete pavement that has not been flattened by the roller 5, avoiding it from falling on the cement concrete pavement that has been flattened by the roller 5, thereby ensuring the quality of the cement concrete pavement.

[0037] The scraper 9 includes a fixed plate 901, a mounting plate 902 and a rubber plate 903. Both ends of the fixed plate 901 are fixedly connected to the ends of the two rotating rods 8 respectively. The mounting plate 902 is fixedly connected to one side of the fixed plate 901, and a card slot is provided on the mounting plate 902. One side of the rubber plate 903 is provided with a groove adapted to the card slot, so that the rubber plate 903 can be clamped on the mounting plate 902. After the rubber plate 903 is used for a long time, it is convenient to replace the rubber plate 903. Since the rubber plate 903 is in a pointed cone shape, it is convenient for the pointed cone part of the rubber plate 903 to fit the outer wall of the drum 5, so that the rubber plate 903 can scrape off the cement concrete adhered to the outside of the drum 5.

[0038] A magnet 3 is fixedly connected to the connecting rod 2, and the rotating rod 8 is made of a material that can be adsorbed and fixed by the magnet 3. When the scraper 9 is not needed, the two rotating rods 8 can be rotated upward and fit into the magnet 3. The magnet 3 will adsorb and fix the two rotating rods 8. At this time, the scraper 9 leaves the roller 5 and is fixed, thereby facilitating the roller 5 to level the cement concrete pavement.

[0039] In addition, in order to prevent cement concrete from entering the interior of the drum 5 from both ends when the drum 5 is working;

[0040] Both ends of the drum 5 are provided with fixing rings 6, the outer wall of the fixing ring 6 is fixedly connected to the inner wall of the drum 5, and the fixing ring 6 can shield the two ends of the drum 5 to prevent cement concrete from entering the interior of the drum from both ends and affecting the normal operation of the drum 5.

[0041] Working principle of the roller type cement concrete pavement flattener:

[0042] During normal use, the two rotating rods 8 can be rotated upward to fit the magnets 3, and the magnets 3 will absorb and fix the two rotating rods 8. At this time, the scraper 9 leaves the roller 5 and is fixed, so that the road surface flattener can be moved back and forth by holding the push rod 1, so that the roller 5 rolls back and forth on the cement concrete road surface. During the rolling process of the roller 5, the roller 5 will roll on the cement concrete road surface through the fixed shaft 7, so that the roller 5 can perform the leveling work of the cement concrete road surface.

[0043] When it is necessary to clean the cement concrete adhered to the surface of the drum 5, the two rotating rods 8 are rotated downward until the pointed cone portion of the rubber plate 903 on the scraper 9 fits the outer wall of the drum 5. At this time, the scraper 9 can keep fitting the outer wall of the drum 5 by its own gravity. Then, the drum 5 is pushed forward by the push rod 1, and the outer wall of the drum 5 and the scraper 9 are relatively displaced, so that the scraper 9 scrapes off the cement concrete adhered to the outer wall of the drum 5.

[0044] In the later stage of cement concrete pavement leveling, the roller 5 can be directly pushed forward to move. At this time, the scraper 9 scrapes off the cement concrete adhered to the outer wall of the roller 5, and makes the scraped cement concrete fall along the inclined outer wall of the scraper 9, and then falls back to the cement concrete pavement in front of the roller 5, and is flattened by the roller 5. As the roller 5 keeps rolling forward, while flattening the cement concrete pavement, the cement concrete adhered to the outer wall of the roller 5 is scraped onto the uneven cement concrete pavement for flattening.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
