Technical Field
[0001] The utility model relates to the technical field of road engineering construction, in particular to an attached lateral protection and compaction operation device for an asphalt roller. Background Art
[0002] In the existing technology, road surface structures often use asphalt surface layers, including hot-mix asphalt mixtures, warm-mix asphalt mixtures, penetrated asphalt macadam, or asphalt surface treatment. Usually carried out as the last step in a road project, construction machinery may collide with curbs, edge structures, and the like during construction, causing damage that is difficult to repair. Roller operations require that the rolling operation reach the edge of the asphalt surface layer. In actual construction, rollers are the construction machinery that most frequently collide with curbs and other structures. Construction projects urgently need a device to protect curbs and other road structures from collisions with rollers. Utility Model Content
[0003] The purpose of the utility model is to provide an attached lateral protection and compaction device for an asphalt roller, so as to solve the problems raised in the above-mentioned background technology.
[0004] To achieve the above objectives, the present invention provides the following technical solutions:
[0005] An attached lateral protection and compaction device for an asphalt roller comprises a connecting portion mounted on the outside of the roller's front wheel beam; the connecting portion comprises a pressure chamber, a vertical shaft slidably connected to the interior of the pressure chamber, and a horizontal shaft rotatably connected to the bottom of the vertical shaft; compacting wheels are mounted on both ends of the horizontal shaft, and airbags are provided on the outside of the compacting wheels.
[0006] As a further solution of the present invention: the upper part of the connecting part is mounted on the road roller by fixing bolts.
[0007] As a further solution of the present invention: the pressure chamber is provided with a limiting mechanism for preventing the vertical shaft from falling off.
[0008] As a further solution of the present invention: the pressure chamber is at a constant pressure, and the pressure value is 20MP.
[0009] Compared with the prior art, the beneficial effects of the present invention are: by attaching the device to the outer side of the front wheel of the roller, the operating range of the roller is widened, so that the driving path of the roller maintains a certain distance from the edge of the road, avoiding the structures on the edge of the road being damaged by the roller; the side airbags of the device can effectively prevent the structures on the edge of the road from being scratched by the roller and the device: the compacting wheel of the device forms a downward compacting effect of the rubber wheel, and the edge of the asphalt surface layer of the road is tight and dense, avoiding water damage to the asphalt surface layer at this position; the device is easy to install and does not affect the normal use of the roller after disassembly.

[0014] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0015] See also Figure 1-3 The utility model provides an attached lateral protection and compaction device for an asphalt roller, the structure of which includes a connecting part 1, a vertical shaft 2, a compaction wheel 3, a pressure chamber 4, a fixing bolt 5, a horizontal shaft 6, and an airbag 7.
[0016] In this example, the fixing bolt 5 is installed on the upper part of the connecting part 1, and the connecting part 1 is installed on the outside of the front wheel beam of the roller; the connecting part 1 contains a pressure chamber 4, and the vertical shaft 2 is slidably connected to the inside of the pressure chamber 4. The pressure chamber 4 contains a limit mechanism to prevent the vertical shaft 2 from falling off; the horizontal shaft 6 is rotatably connected to the bottom of the vertical shaft 2; the compacting wheels 3 are installed at both ends of the horizontal shaft 6, and the outside of the compacting wheels 3 is an airbag 7.
[0017] The connecting part 1 is the connecting part of the device installed on the roller, and the connection is tightened by the fixing bolt 5; the pressure chamber 4 transmits downward pressure to the compacting wheel 3 through the vertical shaft 2, and the vertical shaft 2 is linked to the steering operation of the roller to pressurize the pressure chamber 4 and limit the adjustment of the wheel bottom of the compacting wheel 3 to be consistent with the wheel bottom height of the front wheel of the roller, and to form sufficient downward pressure, so that when the compacting wheel 3 rolls on the asphalt surface layer, it squeezes and compacts the asphalt surface layer, completing the asphalt compaction operation. The pressure chamber 4 is constant to ensure the downward pressure. The numerical value can be obtained from the test section operation, because the current specifications generally require an 18T gravity roller. According to the estimated rolling area, the actual pressure is about 20MP; the horizontal axis 6 can rotate slightly at the connection point with the vertical axis 2, so that the compacting wheel 3 of the device follows the steering of the front wheel of the roller; the outer side of the compacting wheel 3 is an airbag 7, which can deform and shrink when under pressure to prevent the compacting wheel 3 from scraping or colliding with road structures, so that lateral structures such as curbstones are not scraped by the front wheel of the roller during the compaction operation.
[0018] Example usage scenario: During the construction of the asphalt surface layer of a road project, for example, after the asphalt paving of the surface layer is completed, the edges can be neat and beautiful, and structures such as curbs, lamp poles, and traffic sign poles have been installed on site. The asphalt surface layer construction adopts three compaction processes: initial compaction, secondary compaction, and final compaction. Before the surface layer construction, workers install this device on the outer side of the front wheel beam of the roller responsible for rolling the asphalt edge. The outermost roller operating width can achieve the compaction of the edge asphalt surface layer while maintaining a certain distance from the roller body, preventing the roller from colliding or scratching with the road curb. During operation, the bottom of the compacting wheel 3 of this device is flush with the front wheel of the roller, and the pressure chamber 4 applies downward pressure to the compacting wheel 3, so that the asphalt surface layer under the compacting wheel 3 is compacted and dense, reaching the compaction degree required by the road engineering construction specifications and design documents.
[0019] The preferred embodiments of the present application are described in detail above, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of the present application.
