Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] One embodiment provided by this utility model: as follows Figure 1 As shown, a road surface flattening device includes a connecting frame 1, a rolling assembly 2, an oil dispensing assembly 3, an oil layer coating assembly 4, an obstacle removal and cleaning assembly 5, and a rolling assembly surface cleaning assembly 6.

[0027] like Figure 1 As shown, the rolling assembly 2 is rotatably connected to the inner side of the connecting frame 1. When the device is used in the construction of highway pavement, it can fix the different running equipment to the connecting positioning part 11 of the connecting frame 1. When the running equipment moves forward, the rolling assembly 2 rolls forward to press the road surface.

[0028] like Figure 2As shown, the rolling assembly 2 includes a roller 21 and a surface layer 22. The roller 21 is rotatably connected inside the connecting frame 1, and multiple sets of surface layers 22 are spliced ​​and installed on the surface of the roller 21. After prolonged use, the surface of the rolling assembly 2 may develop some damage or deformation, making it no longer a complete cylinder. This will affect the flatness of the road surface. Therefore, a detachable combination surface layer 22 is installed on the outer periphery of the roller 21. Regularly replacing the surface layer 22 can ensure the rolling effect on the road surface and extend the service life of other components of the equipment. The splicing structure of multiple sets of surface layers 22 ensures that during the replacement of the surface layer 22, it is not necessary to remove the rolling assembly 2 from the connecting frame 1. It is only necessary to move forward a certain distance while installing each set onto the roller 21 one by one.

[0029] like Figure 3 As shown, when the surface layers 22 are installed on the roller 21 in groups, since the surface layer 22 also includes a connecting and fixing layer 221 and a belt layer 222, the connecting and fixing layer 221 and the belt layer 222 are fixedly connected. The connecting and fixing layer 221 is screwed on the roller 21, and the belt layers 222 of adjacent surface layers 22 are inserted end to end. In the direction around the roller 21, one end of the belt layer 222 of each group of surface layers 22 extends beyond the connecting and fixing layer 221, and the other end of the connecting and fixing layer 221 extends beyond the belt layer 222. The edge of the connecting and fixing layer 221 at the end of the connecting and fixing layer 221 that extends beyond the belt layer 222, as well as the edge of the connecting and fixing layer 221 near the top and bottom surfaces of the cylinder of the roller 21, are fixed to the roller 21 by screws, thus completing the positioning of the connecting and fixing layer 221, making the surface layer 22 less prone to loosening and maintaining the regularity of the outer circumference. The belt layer 222 extending beyond the connecting and fixing layer 221 has a raised edge 2221, and the belt layer 222 extending beyond the connecting and fixing layer 221 has a recess 2222. When multiple sets of surface layers 22 are combined and fixed around the roller 21, the raised edge 2221 of each set of belt layers 222 can be inserted into the recess 2222 of the adjacent belt layer 222. This prevents the splicing edges of the belt layers 222 from lifting, and ensures that the outer surface of the multiple sets of surface layers 22 at the splicing position can smoothly form a complete arc. Moreover, in the direction of the rolling assembly 2, the end of the belt layer 222 with the raised edge 2221 contacts the ground first, and then the end of the next set of belt layers 222 with the recess 2222 contacts the ground, improving the flatness of the road surface after rolling.

[0030] like Figure 4As shown, an oil outlet assembly 3 is installed on the connecting frame 1. The oil outlet assembly 3 includes an oil tank 31, an oil inlet 32, and an oil outlet 33. The oil tank 31 is mounted on the connecting frame 1. The oil inlet 32 ​​is located at the top of the oil tank 31, and the bottom of the oil tank 31 extends through the connecting frame 1. The oil outlet 33 is located below the connecting frame 1. Multiple sets of oil outlets 33 are arranged and distributed above the rolling assembly 2. Figure 5 and Figure 6 As shown, an oil coating assembly 4 is provided in front of the rolling assembly 2 in the forward direction of the connecting frame 1. The oil coating assembly 4 includes a first bracket 41, a hydraulic cylinder 42, a positioning seat 43, a support frame 44, and a brush 45. Both ends of the support frame 44 are connected to the first bracket 41. A hydraulic cylinder 42 is provided between one set of the first bracket 41 and the support frame 44. The body of the hydraulic cylinder 42 is located on the first bracket 41, and the output end of the hydraulic cylinder 42 is connected to the support frame 44. The support frame 44 is laterally slidably connected to the first bracket 41. The brush 45 is connected to the lower part of the support frame 44. Two sets of positioning seats 43 are provided. Both ends of the support frame 44 are connected to the positioning seats 43, and both ends of the brush 45 are movably connected and rest on the two sets of positioning seats 43. The two ends of the brush 45 rest in the grooves of the positioning seats 43, and the transverse edges of the two ends of the brush 45 can limit the rotation of the brush 45.

[0031] Oil is added to the oil tank 31 through the oil inlet 32. As the roller assembly 2 rotates, oil flows evenly from the oil outlet 33 onto the surface of the roller assembly 2 below. The oil outlets 33 are arranged on the side slightly forward from the top center of the roller assembly 2, ensuring that the oil flows only to the side to be spread by the brush 45, thus conserving oil. Driven by the oil cylinder 42, the oil coating assembly 4 uses the brush 45 to move laterally back and forth. The brush 45 is tilted at an angle, matching the contact angle between its bottom surface and the roller assembly 2, increasing the contact area and allowing the oil to be evenly applied to the surface of the roller assembly 2. As the brush 45 repeatedly applies asphalt to the roller assembly 2, some asphalt residue may accumulate on it, affecting the application of the oil. Therefore, after prolonged use, the brush 45, resting in the groove of the positioning seat 43, can be removed and replaced.

[0032] The oil coating component 4 evenly coats the oil liquid flowing from the oil outlet component 3 onto the surface of the rolling component 2. Since the existing rolling component 2 will stick some asphalt to the surface when rolling the asphalt road, resulting in missing asphalt and potholes on the rolled road, the oil liquid here plays a certain role in isolating the surface, reducing the phenomenon of asphalt sticking to the surface of the rolling component 2, thereby reducing potholes caused by the rolling component 2 carrying away some asphalt, and improving the smoothness of the road surface.

[0033] like Figure 7As shown, the rolling assembly 2 is also provided with an obstacle removal and cleaning assembly 5 in the forward direction. Two sets of obstacle removal and cleaning assemblies 5 are provided and symmetrically distributed on both sides of the connecting frame 1. The obstacle removal and cleaning assembly 5 includes a second bracket 51, a baffle 52 and a shovel 53. One end of the second bracket 51 is hinged to the connecting frame 1 and the other end is hinged to the baffle 52. The baffle 52 has a folded line shape and the shovel 53 is fixed to the bottom edge of the baffle 52. Rotate and adjust the second bracket 51 and the baffle 52 so that the baffle 52 is parallel to the road surface. At the same time, the height between the baffle 52 and the road surface can be adjusted according to the size of the debris to be cleaned. While the rolling assembly 2 moves forward to roll the road surface, the obstacle removal and cleaning assembly 5 moves forward accordingly. The shovel 53 can remove the blocky particles on the road surface to be rolled. Along the direction of the baffle 52, the blocky particles are collected to both sides of the road surface to be rolled. Since blocky particles are easily dropped out later when they are pressed into the asphalt of the road surface, and the potholes on the road surface will affect the driving of vehicles, the removal of blocky particles can ensure the integrity of the road surface after rolling and improve the later use effect of the highway road surface.

[0034] like Figure 8 As shown, the rear surface of the rolling assembly 2 contacts the surface cleaning assembly 6 of the rolling assembly. The surface cleaning assembly 6 of the rolling assembly includes a third bracket 61 and a scraper 62. Two sets of third brackets 61 are provided and fixed on both sides of the connecting frame 1 respectively. The scraper 62 is installed between the third brackets 61 at the corresponding position of the rolling assembly 2. The scraper 62 contacts the upper surface of the rolling assembly 2. Even if the rolling assembly 2 is coated with oil, some asphalt may still stick to the part of the road surface after the rolling assembly 2 has rolled over the asphalt. After the rolling assembly 2 rotates to the other side of the connecting frame 1, the scraper 62 scrapes off these residual asphalts. This avoids the situation where the asphalt solidifies on the surface of the rolling assembly 2 and leaves a dent in the road surface during the next rolling, thus improving the smoothness of the road surface after rolling.

[0035] The above are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.
