In this embodiment, the steel wheel can satisfy the rigidity required by the first roller 110 for road rolling, and the rubber tire can satisfy the elasticity required for road rolling, so as to ensure the road surface quality after road rolling. When applied to road roller 10, the inflated rubber tires may wrap around first roller 110 to provide a larger rolling area for the rubber tires than for conventional tire machines or combination machines. The vibration mechanism 130 is arranged in the steel wheel, so that the steel wheel can further improve the road rolling quality through vibration when rolling the road surface. Because the outer tread of the first roller 110 and the inner smooth layer 1212 are attached to each other, friction between the tire body 122 and the first roller 110 is reduced, and the service life of the tire body 122 is prolonged.
Example 8
As shown in fig. 5, the present embodiment provides a laminating apparatus 100. In addition to the technical features of the above embodiment, the present embodiment further includes the following technical features:
the second roller 120 further includes: the inner smooth layer 1212 and the wear-resistant layer 1214, the inner smooth layer 1212 is arranged on the surface of the tire body 122, which is in contact with the first roller 110; a wear layer 1214 provided on the outer circumferential surface 1220; the inner smooth layer 1212 and the outer wheel face 1102 are attached to each other, and the wear-resistant layer 1214 is used for rolling the road surface.
In this embodiment, because the inner smooth layer 1212 is attached to the outer wheel surface of the first roller 110, friction between the tire body 122 and the first roller 110 is reduced, and the service life of the tire body 122 is prolonged. In addition, the smooth inner smooth layer 1212 facilitates the coupling and uncoupling of the second roller 120 with the first roller 110. For example, the inner side of the rubber tire may be smooth and non-wear resistant plain material as the inner smooth layer 1212. An inflatable rubber tire is inflated to enable the inner smooth layer 1212 to press tightly against the smooth steel wheel. Since the wear-resistant layer 1214 rubs in contact with the road surface, the service life of the second roller 120 can be increased, and for example, a wear-resistant rubber layer may be provided on the outer side of a rubber tire.
Example 9
As shown in fig. 11 and 12, the present embodiment provides a roller 10 comprising: the vehicle body 200, the driving mechanism 300 and the rolling device 100 in any embodiment, wherein the driving mechanism 300 is connected with the rolling device 100 and is suitable for driving the rolling device 100 to roll a road surface.
In this embodiment, the rolling device 100 is applied to the road roller 10, the first roller 110 is first mounted on the vehicle body 200, the first roller 110 is a steel wheel, then the second roller 120 is installed according to the requirement, when installing, the frame is jacked up to the verification height by the jack, the steel wheel is wiped by the rag to remove unnecessary silt and dust, the second roller 120 is spread out and passes through the gap between the steel wheel and the frame, the inner smooth layer 1212 of the second roller 120 is mutually attached to the outer wheel surface of the steel wheel, the first connecting part 124 and the second connecting part 126 at the two ends of the tire body 122 are aligned to ensure that the bolt holes at the two ends are aligned, after being aligned, the rubber tire is screwed by a plurality of connecting bolts, and after being installed and fixed, the rubber tire is inflated into the inner cavity of the tire body 122 through the inflation hole 128, the inner smooth layer 1212 on the inner side of the inflated rubber tire is pressed with the smooth surface of the steel wheel, and the wear-resistant layer 1214 is arranged on the outer side of the inflated rubber tire. After the air is inflated to reach the set pressure, the jack is decompressed, and the wear-resistant layer 1214 is in contact with the road surface, so that the working state can be achieved.
When the combined roller needs to be restored into a double-steel-wheel roller, the frame is also jacked up, air in the tire body 122 is discharged from the air charging hole 128, the fastener 1210 is unscrewed, the second roller 120 is drawn out, and finally the jack is used for releasing pressure and removing the pressure, so that the double-steel-wheel state can be restored. The collected rubber tire can be rolled up and bound into a cylinder or folded for storage.
In addition, since the roller 10 provided according to an embodiment of the present invention includes the rolling compaction apparatus 100 according to any embodiment of the present invention, it has all the benefits of the rolling compaction apparatus 100 according to any embodiment of the present invention.
