Technical Field

[0001] The utility model relates to the field of road compacting equipment, in particular to an asphalt concrete compacting device. Background Art

[0002] Asphalt concrete, as a high-quality pavement material, plays a crucial role in transportation construction. Its unique physical and chemical properties enable it to excel in withstanding vehicle loads, resisting environmental erosion, and maintaining a smooth surface. In the construction of asphalt concrete pavements, in addition to selecting high-quality crushed stone and asphalt, strict control of mixing conditions is crucial. These include temperature, mixing time, mixing speed, and other factors to ensure the uniformity and stability of the mixture. Only under these conditions can high-performance asphalt concrete be produced, ensuring the longevity of the pavement and driving safety.

[0003] Generally, asphalt concrete needs to be compacted after pouring. Currently, most asphalt concrete pouring and compaction processes use small compactors. However, the compaction roller components in existing compactors are heavy overall, and when the compaction roller is installed on the compactor, the operation is difficult. After the compaction work is completed, it is inconvenient to remove the compaction roller and place it for storage. When the compaction roller fails or is damaged, it is inconvenient to repair or replace it, which is labor-intensive and increases labor hours. Utility Model Content

For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. A person of ordinary skill in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0032] Example:

[0033] An asphalt concrete compacting device 2 includes a compacting machine 1, the compacting machine 1 is detachably connected to a compacting device 2, and the compacting device 2 includes a fixed frame 21 and a compacting component 22;

[0034] The compacting component 22 includes a compacting roller 221, and connecting shafts 222 are provided at both ends of the compacting roller 221. The compacting component 22 is rotatably connected to the fixed frame 21 through the connecting shaft 222. A plurality of mounting grooves 223 are provided inside the compacting roller 221, and a weighting device is detachably connected inside the mounting grooves 223. The compacting component 22 is electrically connected to the compactor 1 through a wiring harness.

[0035] The multiple mounting slots 223 within the compaction roller 221, with their unique design, allow for flexible and varied weight adjustment. Without the need for additional weighting devices, the overall weight of the compaction roller 221 remains relatively light, significantly reducing the burden on operators during transfer, loading, and maintenance. When the compaction roller 221 is put into actual operation, by adding weighting devices to these reserved mounting slots 223, the overall weight of the compaction roller 221 can be precisely adjusted to meet the actual weight requirements of the equipment in different operating environments, thereby ensuring the stability and efficient operation of the equipment under various operating conditions.

[0036] Specifically, during actual operation, the operator can flexibly choose whether to add a weighting device to the mounting slot 223 according to the specific working conditions, thereby achieving precise control of the weight of the compacting roller 221. This control method is both simple and intuitive, and can ensure that the compacting roller 221 can perform optimally in various operating environments.

[0037] Combined with the accompanying drawings Figures 1-8 , there are at least four mounting grooves 223, and the weighting devices are all screwed into the mounting grooves 223. The weighting devices include a weighting column 224, a locking plate 225 and a bolt. One end of the weighting column 224 is arranged inside the mounting groove 223, and the other end of the weighting column 224 extends out of the mounting groove 223 and is welded to the locking plate 225. A pair of through holes are provided on the surface of the locking plate 225, and a pair of threaded holes are provided on the end surface of the compacting roller 221 corresponding to the through holes. The bolts pass through the through holes and are screwed into the threaded holes for fixing the weighting column 224 to the compacting roller 221.

[0038] To illustrate, align one end of the weight column 224 with the mounting slot 223 and gently screw it in, ensuring that the contact surface between the weight column 224 and the mounting slot 223 fits tightly without any gap. At the other end of the weight column 224, the compacting roller 221 needs to be moved directly above the locking plate 225 so that the through hole on the locking plate 225 is aligned with the threaded hole on the compacting roller 221. Then, we take out the bolt, pass it through the through hole on the locking plate 225, and screw it into the threaded hole. During the screwing process, we need to keep the bolt vertical and tighten it with appropriate force to ensure that the connection between the weight column 224 and the compacting roller 221 is firm and reliable.

[0039] Specifically, in actual use, the weighting device can be increased or decreased as needed to meet the needs of different working scenarios. At the same time, since the weighting device is connected to the compacting roller 221 by bolts, installation and removal are very convenient, greatly improving work efficiency.

[0040] Combined with the accompanying drawings Figures 1-8 The fixed frame 21 includes a first frame 211, a hinge shaft 212 and a second frame 213. The second frame 213 is movably connected to the first frame 211 through the hinge shaft 212, and the end of the second frame 213 that is not connected to the hinge shaft 212 is detachably connected to the first frame 211.

[0041] To illustrate, the first frame 211 and the second frame 213 serve as the main components of the fixed frame 21, jointly carrying out the functions of fixing and supporting. The hinge shaft 212, as the key component connecting the two, allows the second frame 213 to move within a certain range relative to the first frame 211, thereby meeting the needs of different usage scenarios.

[0042] Combined with the accompanying drawings Figures 1-8 The fixed frame 21 also includes a plug-in plate 215 and a limiting component 216. The plug-in plate 215 is welded to the end of the second frame 213 that is not connected to the hinge shaft 212, and is inserted into the clamping groove 214 opened inside the first frame 211. The limiting component 216 is inserted into the limiting groove opened by the first frame 211 and the plug-in plate 215. The limiting component 216 includes a limiting plate and an end plate. The limiting plate is inserted into the limiting groove opened by the first frame 211 and the plug-in plate 215. The end plate is welded to the top surface of the limiting plate and is screwed and fixed to the first frame 211.

[0043] To illustrate, the provision of the plug-in board 215 facilitates connection between the second frame 213 and the first frame 211. Inserting the plug-in board 215 into the mounting slot 223 allows for a tight fit between the two. The stopper plate, inserted into the stopper slot, effectively limits the displacement of the plug-in board 215 within the mounting slot 223, preventing it from shaking or falling off during use. The end plate is welded to the top surface of the stopper plate and screwed to the first frame 211, further strengthening the connection between the stopper component 216 and the fixed frame 21, improving the stability of the entire structure.

[0044] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
