Abstract
Description
Technical Field
[0001] The invention discloses an automatic deviation correction device for road surface flatness and linear shape, which is used for road surface flatness and linear shape correction and belongs to the technical field of flatness and deviation correction devices. Background Art
[0002] Under high temperature conditions, the asphalt film between particles in the asphalt mixture may undergo shear deformation, resulting in relative displacement of aggregate particles. When the repeated rolling of wheels causes the load stress to exceed the stability limit of the asphalt mixture, the flow deformation will continue to accumulate, thus forming rutting. Or when the road is subjected to a large amount of heavy traffic, the load exceeds the strength of each layer of the pavement, which may cause permanent deformation of each structural layer including the roadbed, thus forming structural rutting.
[0003] If the road surface is not smooth enough, vehicles will generate uneven pressure and friction on the road surface during driving. This uneven force can easily cause the road surface material to flow and deform, thus forming rutting. Therefore, maintaining good road surface smoothness is one of the important measures to reduce rutting. Pavers and compactors are important equipment for road surface leveling. However, the road surface compactors in the prior art have the following technical problems:
[0004] 1. The compactor can only compact the road surface, but cannot simultaneously correct the road surface’s linear deviation during the compaction process, which affects the road’s performance and safety.
[0005] 2. The roller compacts the road surface with its own weight to improve the road surface's bearing capacity and flatness. During the roller construction process, due to the unevenness of the road surface material or the limitations of the equipment itself, the road surface may become uneven or insufficiently compacted in some areas, which can easily cause poor road surface flatness and subsequent problems such as rutting.

[0041] Example 1
[0042] In order to solve the problem that the compactor can only compact the road surface but cannot simultaneously correct the road surface linearity during the compaction process, thus affecting the performance and safety of the road. Figure 1-6 As shown, a device for automatically correcting the flatness and linearity of a road surface is provided, comprising a vehicle body 1, a front roller 2 and a rear roller arranged on the vehicle body 1, located on one side of the front roller 2, and an edge correction structure 3 is arranged on the vehicle body 1; the edge correction structure 3 comprises a cutting correction structure 4 for edge cutting and a filling correction structure 5 for cooperating with the cutting correction structure 4 to perform edge filling.
[0043] In practice, after the paver paved the road surface according to the design line of the road surface, the edge may be paved over the design line or less than the design line. In this case, the front roller 2 and the rear roller can be controlled to move to perform the road surface compaction process, and the paving material that exceeds the design line can be cut by the cutting correction structure 4, and the excess paving material after cutting can be recovered by the filling correction structure 5 and used to fill the side less than the design line. This embodiment can perform linear deviation correction before compaction to achieve the simultaneous compaction of the compactor and linear deviation correction, so that the performance and safety of the road are better.

When in use, the first longitudinal telescopic mechanism 7 on one side or both sides can be controlled to control the cutting plates 8 on both sides to descend according to needs to achieve single-sided cutting or double-sided cutting.
[0046] In practice, the height is adjusted by rising and falling the first longitudinal telescopic mechanism 7 so that the cutting board 8 can cut the paving material. When the device moves forward, the cutting board moves along the designed edge line to achieve edge cutting. The structure is simple and the cutting board can be raised and lowered as needed to make cutting corrections.
[0047] Example 3
