Description

Technical Field

[0001] The present invention relates to the fields of road construction and material testing, and specifically to a gyratory compactor for asphalt mixtures. Background Art

[0002] A gyratory compactor for asphalt mixtures is a device specifically used to simulate and evaluate the compaction effect of asphalt mixtures in road construction. Such instruments help engineers predict and verify the performance of the materials used in actual applications by simulating the compaction effect of vehicles driving on the road surface.

[0003] Existing gyratory compactors for asphalt mixtures usually include a fixed compaction unit that can apply vertical pressure to the asphalt mixture placed therein. These devices evenly apply pressure to the mixture through electric or hydraulic machinery to simulate the compaction effect of heavy vehicles driving on the road surface. Effectively, these devices can evaluate the compaction degree, stability, and bearing capacity of the mixture under specific conditions, providing basic data for road design and construction.

[0004] Although existing devices can basically complete the compaction test tasks, they usually lack flexibility and are difficult to simulate the actual compaction environment under different road slopes or changing conditions. In addition, existing devices mostly rely on operators to manually load and unload materials, increasing the labor intensity and complexity of the operation. These limitations make the devices insufficient in multi-condition simulation and reducing human dependence, thus affecting the efficiency and universality of the test. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a gyratory compactor for asphalt mixtures. By introducing an adjustable compaction angle mechanism, the present invention enhances the flexibility and automation level of the device. This not only allows for accurate simulation of various slopes and road conditions, but also reduces the labor intensity of the operator through an automatic loading and unloading system, thereby improving the efficiency of the test and the universality of the application.

[0008] A compaction mechanism disposed outside the support mechanism for generating rolling and kneading during the compaction of the asphalt mixture, thereby completing the rotational compaction work of the asphalt mixture, and cooperating with the support mechanism to display the test results;

[0009] An adjustment mechanism is arranged inside the support mechanism and is used to adjust the tilt angle of the sleeve, so as to simulate the compaction state of the asphalt pavement in actual engineering.

[0037] The support mechanism 10 is used to provide stable support for the device, and at the same time used to store the asphalt mixture sample to support the subsequent compaction work and provide the installation space for the subsequent structure. The support mechanism 10 makes the whole device have high stability during operation, and can effectively avoid the accuracy deviation caused by vibration or movement during the compaction process;

[0038] The compaction mechanism 20 is arranged outside the support mechanism 10 and is used to generate rolling and kneading during the compaction of asphalt mixture, so as to complete the rotary compaction work of the asphalt mixture, and cooperate with the support mechanism 10 to display the test results. Through the compaction mechanism 20, the asphalt mixture can be evenly compacted, improving the flatness and service life of the road surface, and ensuring the compaction quality at the same time;

[0039] The double compaction mechanism 30 is arranged inside the support mechanism 10 and is used to reciprocally extrude the asphalt mixture to make it fully compacted. At the same time, it can eject the compacted mixture after compaction, so that there is no need for employees to manually take out the compacted mixture. Through the double compaction of the double compaction mechanism 30, the density of the mixture is further improved, ensuring the durability and bearing capacity of the road. After compaction, it can also eject the compacted mixture, reducing manual intervention and reducing the labor intensity;

[0040] The adjustment mechanism 40 is arranged inside the support mechanism 10 and is used to adjust the inclination angle of the sleeve 106, so as to simulate the compaction state of the asphalt pavement in actual engineering. Through the adjustment mechanism 40, the inclination angle of the sleeve 106 can be adjusted, so that the compactor can simulate various road conditions during the test to better detect the asphalt mixture.

During the rotation, the driving telescopic cylinder 207 is used to jack up and extrude the asphalt mixture by the T-shaped rod 209, so that the pressure plate 203 contacts the asphalt mixture. Thus, the normal non-parallel pressure plate 203 produces a rolling and kneading effect on the asphalt mixture. At the same time, when the motor 201 drives the pressure plate 203 to rotate forward and backward, the limit block 206 squeezes the pressure detector 205 to judge whether the current extrusion strength reaches the use standard.
