Abstract
Description
Technical Field
[0001] This application relates to the field of mechanical equipment technology, and in particular to rotary compactors. Background Technology
[0002] Rotary compactors are commonly used in road laboratories for compacting and preparing circular specimens of hot-mix asphalt mixtures. Rotary compactors are standard equipment in road testing laboratories. Because rotary compactors require the mold to rotate and oscillate to knead the mixture while simultaneously applying pressure, their structure is relatively complex. Existing rotary compactors primarily use a linkage-driven structure, where a stepper motor controls the linkage to rotate the mold. Other types include tray-type structures, where the tilting and rotation of the tray drives the mold in an eccentric rotational motion. Another design uses an eccentric circular base within the rotating platform, directly inserted into the mold to drive its eccentric movement. However, overall, existing rotary compactors are quite complex. While some simpler rotary compactors exist, they often suffer from irregular mechanical movement, leading to mechanical wear and reduced overall reliability.
[0003] In view of this, there is an urgent need to propose a rotary compactor that can simplify the mechanical structure of the rotary compactor while ensuring regular movement of the mechanism, reducing mechanical wear, and improving the overall reliability of the rotary compactor.

[0033] Rotary compactors are commonly used in road laboratories for compacting and preparing circular specimens of hot-mix asphalt mixtures. Rotary compactors are standard equipment in road testing laboratories. Because rotary compactors require the mold to rotate and oscillate to knead the mixture while simultaneously applying pressure, their structure is relatively complex. Existing rotary compactors primarily use a linkage-driven structure, where a stepper motor controls the linkage to rotate the mold. Other types include tray-type structures, where the tilting and rotation of the tray drives the mold in an eccentric rotational motion. Another design uses an eccentric circular base within the rotating platform, directly inserted into the mold to drive its eccentric movement. However, overall, existing rotary compactors are quite complex. While some simpler rotary compactors exist, they often suffer from irregular mechanical movement, leading to mechanical wear and reduced overall reliability.
[0034] To address the aforementioned issues, this application provides a rotary compactor that simplifies the mechanical structure of the rotary compactor while ensuring regular movement of the mechanism, reducing mechanical wear, and improving the overall reliability of the rotary compactor.
[0035] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0036] Figure 1 This is a schematic diagram of the overall structure of the rotary compactor shown in the embodiments of this application. Figure 2 This is a schematic diagram illustrating the structure of the sample mold in the rotary compactor when generating a rotation angle, as shown in the embodiments of this application. Please refer to [link / reference]. Figure 1 and Figure 2The rotary compactor shown in the embodiments of this application may include:
[0037] The system comprises a dual-axis universal swing frame 1, a sample mold 2, a mold rotation drive component, a hydraulic cylinder guide support frame 4, and a lifting hydraulic cylinder 5. Among these, for example... Figure 2 As shown, one end of the sample mold 2 is mounted on the mold rotation drive component, and the other end of the sample mold 2 is connected to the biaxial universal swing frame 1. This allows the mold rotation drive component to drive the sample mold 2 to perform a 360° conical swing around the axis of the biaxial universal swing frame 1, thereby kneading the asphalt mixture sample in the sample mold 2. This ensures that the overall mechanism can move in a regular manner, reduces mechanical wear, and improves the overall reliability of the rotary compactor.
[0038] Furthermore, the mold rotation drive component is mounted on the hydraulic cylinder guide support frame 4, and the lifting piston rod 51 of the lifting cylinder 5 passes through the hydraulic cylinder guide support frame 4 and the mold rotation drive component and abuts against the mold base plate 21 in the inner cavity of the sample mold 2, so that the lifting piston rod 51 can provide lifting and compaction power to the sample mold 2 for compacting the asphalt mixture sample in the sample mold 2.
[0039] The rotary compactor provided in this application includes a biaxial universal swing frame, a sample mold, a mold rotation drive component, a hydraulic cylinder guide support frame, and a lifting cylinder. One end of the sample mold is mounted on the mold rotation drive component, and the other end is connected to the biaxial universal swing frame. This allows the mold rotation drive component to drive the sample mold to perform a 360° conical swing around the axis of the biaxial universal swing frame, ensuring regular movement of the entire mechanism, reducing mechanical wear, and improving the overall reliability of the rotary compactor. Furthermore, the mold rotation drive component is mounted on the hydraulic cylinder guide support frame. The lifting piston rod of the lifting cylinder passes through the hydraulic cylinder guide support frame and the mold rotation drive component, abutting against the mold base plate inside the sample mold cavity. This allows the lifting piston rod to provide lifting and compaction power to the sample mold, while the hydraulic cylinder guide support frame and the mold rotation drive component do not apply lifting and compaction power to the lifting piston rod during the loading process, achieving the most compact and reasonable rotary compaction combination.
[0040] In summary, the rotary compactor of this application can simplify the mechanical structure of the rotary compactor while ensuring regular movement of the mechanism, reducing mechanical wear, and improving the overall reliability of the rotary compactor.
[0041] In some embodiments, the mold rotation drive component may include, but is not limited to, the mold tray 31, the drive chassis 32, and the hollow rotary power mechanism 33 (i.e., the hollow rotation mechanism). Wherein, as... Figure 1 and Figure 2As shown, the drive chassis 32 is connected between the mold tray 31 and the hollow rotary power mechanism 33, so that the hollow rotary power mechanism 33 can provide rotational driving force to the drive chassis 32, driving the mold tray 31 to tilt and rotate.
[0042] Furthermore, in this embodiment, the hollow rotary power mechanism 33 has a hollow channel, through which the lifting piston rod 51 passes and abuts against the mold base plate 21. This allows the hollow structure of the hollow rotary power mechanism 33 to provide movement space for the lifting piston rod 51, making the rotary compactor in this embodiment more compact.
[0043] In some embodiments, the mold tray 31 may be provided with At least three guide wheels ,Should At least three guide wheels It adheres closely to the outer surface of the sample mold 2, thereby making the sample mold 2 rotate more smoothly and further reducing mechanical wear.
[0044] In some embodiments, a removable reaction force plate 22 may be installed on the other end of the sample mold 2 away from the mold base plate 21, with an asphalt mixture sample 23 placed between the removable reaction force plate 22 and the mold base plate 21. It is understood that after the removable reaction force plate 22 is installed, during the rotational compaction of the asphalt mixture sample 23, the removable reaction force plate 22 can provide a reaction force opposite to the lifting and compaction force of the lifting piston rod 51; after the asphalt mixture sample 23 has completed rotational compaction, the removable reaction force plate 22 can be opened, thereby ejecting the asphalt mixture sample 23 from the sample mold 2 via the lifting piston rod 51.
