Problems solved by technology

At present, the compaction of asphalt pavement is mostly carried out according to the method of static pressure with double steel rollers - multiple vibration compaction with double steel wheels - compaction with tire rollers - static pressure with double steel wheels. For large projects, two types of machines can be used to interact However, for small maintenance projects, the cost of using two types of road rollers at the same time is high, or when a double-steel wheel or tire road roller fails to shut down in a large-scale project, it must be shut down or other machines must be rented to supplement, delaying the construction period and high costs

Embodiment 1

[0051] like image 3 and Figure 7 As shown, the present embodiment provides a rolling device 100 for rolling road surfaces. The rolling device 100 includes: a first roller 110 and a second roller 120. The first roller 110 has an outer wheel surface that can be used for rolling road surfaces. 1102 ; the second roller 120 has an outer peripheral surface 1220 that can be used for rolling the road surface; wherein, the second roller 120 is sleeved on the outer surface 1102 , the first roller 110 is a rigid wheel, and the second roller 120 is an elastic wheel.

[0052] In this embodiment, by detachably connecting the second roller 120 on the outer wheel surface 1102 of the first roller 110, when the first roller 110 is required as the working wheel in the first working state, the second roller 120 can be removed, so that the first The roller 110 is in contact with the road surface. When the second roller 120 is required as the working wheel in the second working state, the second...

Embodiment 2

[0054] like image 3 , Figure 4 and Figure 8 As shown, this embodiment provides a rolling device 100 . In addition to the technical features of the above-mentioned embodiments, this embodiment also includes the following technical features:

[0055] The second roller 120 includes: a tire body 122, a first connecting portion 124 and a second connecting portion 126, the first connecting portion 124 is arranged on the tire body 122; and the second connecting portion 126 is arranged on the tire body 122; wherein, the tire The body 122 has a ring structure, and the first connecting portion 124 is detachably connected to the second connecting portion 126 .

[0056] In this embodiment, the first connecting portion 124 and the second connecting portion 126 can be made of a material different from that of the tire body 122. Through the detachable connection between the first connecting portion 124 and the second connecting portion 126, the tire body 122 can be spliced ​​together. ...

Embodiment 3

[0058] like Figure 4 As shown, this embodiment provides a rolling device 100 . In addition to the technical features of the above-mentioned embodiments, this embodiment also includes the following technical features:

[0059] The second roller 120 further includes: a concave-convex interlocking structure 1200 ; wherein the concave-convex interlocking structure 1200 is used to connect the first connecting part 124 and the second connecting part 126 in a concave-convex fit.

[0060] In this embodiment, the first connection part 124 and the second connection part 126 are connected by concave-convex fit, which improves the tightness of the connection structure between the first connection part 124 and the second connection part 126, so that the first connection part after connection The outer surface and the inner surface of the connecting portion 124 and the second connecting portion 126 are easier to achieve flatness, which will not affect the quality of the rolled road surfac...

Abstract

The invention provides a rolling device and a road roller, and is used for rolling a road surface. The rolling device comprises a first roller which is provided with an outer wheel surface for rollingthe road surface; and a second roller which is provided with an outer peripheral surface for rolling the road surface, wherein the second rolling wheel is arranged on the outer wheel surface in a sleeving mode, the first rolling wheel is a rigid wheel, and the second rolling wheel is an elastic wheel. By detachably connecting the second rolling wheel to the outer wheel surface of the first rolling wheel, the two working states can be switched in time, the switching time of the working states is saved, the switching efficiency of the working states is improved, and the cost brought by a switching tool can be saved. The elastic material of the second roller is more beneficial to keeping the effect after the first working state when the first roller is switched to the second working state after the working state.

Description

technical field [0001] The invention relates to the technical field of road construction equipment, in particular, to a rolling device and a road roller. Background technique [0002] In the related art, road rollers for road construction mainly include steel wheel rollers with steel wheel vibration and tire rollers for tire compaction. Steel wheel rollers are mainly used for vibratory compaction and finishing, while tire rollers have good flexibility. Compaction performance, which can make the compacted object obtain a higher surface quality, and at the same time ensure that the aggregate of the compacted road surface is not damaged. At present, the compaction of asphalt pavement is mostly carried out according to the method of static pressure with double steel rollers - multiple vibration compaction with double steel wheels - compaction with tire rollers - static pressure with double steel wheels. For large projects, two types of machines can be used to interact However, ...
