Description

Technical Field

[0001] The utility model relates to the technical field of rutting test machines, in particular to an asphalt mixture rutting test machine with high applicability. Background Art

[0002] The asphalt mixture rutting test is to use a standard molding method to make a standard asphalt plate specimen. At a specified temperature, the tire is pressed on the asphalt plate specimen and walked on it. The number of times the specimen needs to walk for every 1mm increase in deformation during the deformation stability period, that is, the dynamic stability, is measured. Publication No.: CN208091840U discloses a fully automatic asphalt mixture rutting tester, including a workbench, a mounting seat arranged on the workbench, and a sliding seat slidably connected to the mounting seat. The top surface of the workbench is fixed with a test bench for placing the asphalt plate specimen, the sliding seat is provided with a first driving member, and the first driving member is fixed with a pressure wheel assembly for abutting the asphalt plate specimen, and the pressure wheel assembly is driven to rise or fall by the first driving member. The first driving member includes a top seat slidably connected to the top of the protective cover and a first oil cylinder fixed on the top seat. The first oil cylinder can directly drive the pressure wheel assembly to rise or fall. There is no need to install an additional transmission assembly like a motor to convert circumferential rotation into linear motion, which helps to reduce power loss and is more efficient. However, during use, the above technology can only perform horizontal tests on asphalt plate specimens. When a longitudinal experiment is required, personnel are required to manually lift the asphalt plate specimens to place them in a 90° orientation. The operation is cumbersome and the test efficiency is low, which needs to be improved. Utility Model Content

[0025] Embodiment 2

[0026] See also Figure 4-5A connecting plate 16 is fixedly installed on the side of the moving wheel 10, and a bolt 17 is inserted on the surface of the connecting plate 16. A screw hole 18 is provided on the bottom surface of the translation block 9, which can facilitate the disassembly and assembly of the moving wheel 10 and improve the maintenance efficiency of the moving wheel 10.

[0027] Working principle: When conducting a rutting test, the asphalt plate specimen is placed on the tray 23, and then the tray 23 is placed in the placement frame 22. At this time, the cylinder 3 is started, and the output end of the cylinder 3 drives the telescopic rod 4 to move downward, and then the telescopic rod 4 drives the lifting plate 5 to move up and down inside the hood 2. By setting a fixed plate, the slider 6 on the side of the lifting plate 5 slides in the slide groove 8, thereby improving the stability of the lifting plate 5. When the lifting plate 5 moves downward, it will drive the translation block 9 to move downward, so that the translation block 9 can press the moving wheel 10 on the asphalt plate specimen. Then turn on the motor 12, and the output end of the motor 12 drives the screw rod 13 to rotate. The screw rod 13 rotates inside the translation block 9, so that the translation block 9 moves horizontally on the surface of the screw rod 13. The limit block 15 cooperates with the limit groove 14 to improve the stability of the translation block 9, so that the moving wheel 10 can stably move back and forth on the surface of the asphalt plate specimen. At this time, the transverse test of the asphalt board specimen can be completed. When the asphalt board specimen needs to be tested longitudinally, pull the pin 25, the pin 25 slides inside the protrusion 24, and then the pin 25 drives the stopper 26 to squeeze the spring 27. At this time, the pin 25 is disengaged from the inside of the No. 1 socket 28, and then the turntable 21 is rotated, and the turntable 21 is rotated 90° to align the position of the socket with the No. 2 socket 29, and the pin 25 is released. Under the elastic force of the spring 27, the pin 25 can be inserted into the No. 2 socket 29, so that the asphalt board specimen can be tested longitudinally. When the moving wheel 10 needs to be maintained, the bolt 17 is loosened from the screw hole 18, and the moving wheel 10 can be removed from the bottom surface of the translation block 9. The cross plug block 20 is matched with the cross slot 19 to improve the stability between the moving wheel 10 and the translation block 9, so as to avoid shaking of the moving wheel 10 during the experiment and affect the experimental results.
