Description

Technical Field

[0001] This utility model relates to the technical field of rut sample forming machines, and in particular to an asphalt mixture rut sample forming machine. Background Technology

[0002] An asphalt mixture rutting specimen molding machine is an experimental device used to simulate the rutting performance of asphalt pavements. This equipment evaluates the rutting resistance of the mixture under high temperature and pressure conditions by heating the asphalt mixture to a certain temperature and pressing it into a specimen. The working principle of the molding machine is to heat the asphalt mixture with a heating device to achieve a suitable fluidity, and then use a pressure system to press the mixture into a specimen of a specified shape.

[0003] Patent CN218180447U discloses an asphalt mixture rutting sample forming machine. Specifically, the patent discloses a technical solution comprising: a support plate; two parallel slide rails; a limiting component fixedly connected to the bottom outer wall of the support plate for moving the support plate along the length of the slide rails; a transmission component disposed between the two slide rails for adjusting the height of the support plate, wherein the transmission component and the limiting component form a transmission engagement; and a base, with the two slide rails fixedly connected to the top outer wall of the base; and two sliders, each slider being slidably connected to one of the two slide rails, with the support plate fixedly connected to the top outer wall of the two sliders. This solution achieves the technical effect that "because the position of the limiting groove on the transmission base is determined, when the limiting blocks are in the same limiting groove, the squeezing force of the pressing block on the asphalt mixture is the same, thus ensuring the accuracy of the data when the samples produced by this device are used for asphalt performance testing."

[0004] The existing equipment uses only one steel mold box, which means that only one asphalt mixture sample can be formed at a time, resulting in low production efficiency. When multiple samples need to be tested, it is necessary to wait for one forming process to be completed before starting the next one, which greatly reduces work efficiency.

[0005] Therefore, we propose an asphalt mixture rutting sample forming machine. Utility Model Content

[0027] Example

[0028] likeFigures 1-4 As shown, this utility model provides a technical solution: an asphalt mixture rutting sample forming machine, including a workbench 1, which is the basic support structure of the entire device, providing installation positions and a stable working environment for other components. The workbench 1 is equipped with a lifting component, and a steel mold box 8 is provided on the top of the lifting component. A sliding groove is opened on the top of the workbench 1, and the steel mold box 8 is slidably connected inside the sliding groove.

[0029] A support frame 2 is fixedly installed on the top of the workbench 1. A pressure plate 7 is set on the side of the support frame 2 near the workbench 1. Multiple pressure sensors 6 are fixedly installed on the top of the pressure plate 7 to detect the pressure status in real time during the pressing process and ensure the processing quality.

[0030] The lifting assembly includes a pallet 9, a telescopic frame 10, a threaded block 11, and a threaded rod 12. A motor 13 is fixedly installed inside the worktable 1. The output end of the motor 13 is coaxially fixedly connected to the threaded rod 12 via a coupling. The threaded block 11 is threadedly connected to the outer circumference of the threaded rod 12. The threaded block 11 is used to convert the rotational motion of the threaded rod 12 into its own linear motion. When the motor 13 drives the threaded rod 12 to rotate, the threaded block 11 moves along the axial direction of the threaded rod 12, thereby driving the telescopic frame 10 to extend and retract, realizing the lifting and lowering of the pallet 9. The telescopic frame 10 is located inside the worktable 1, and its internal parts are rotatably connected to both ends of the threaded block 11. The function of the telescopic frame 10 is to... The height is changed by its own expansion and contraction deformation, thereby pushing the pallet 9 to rise or fall. When the threaded block 11 moves along the threaded rod 12, it will drive the telescopic frame 10 to expand and contract, thereby driving the pallet 9 to move. The top of the telescopic frame 10 is provided with the pallet 9, and the top of the pallet 9 is provided with an adapter groove. The bottom of the steel mold box 8 is provided with a protruding structure. The top of the pallet 9 is adapted to the bottom of the steel mold box 8. The function of the pallet 9 is to directly support the steel mold box 8 and ensure the stability of the steel mold box 8 during the lifting process. When the pallet 9 rises or falls, it will drive the steel mold box 8 to move synchronously, realizing the vertical position adjustment of the steel mold box 8 to meet the height position requirements of the steel mold box 8 in different processing steps.

[0031] A fixing block 3 is fixedly installed on the outer periphery of the support frame 2. Multiple cylinders 4 are fixedly installed on the bottom of the fixing block 3. A pressing frame 5 is fixedly installed at the end of the cylinder 4 away from the fixing block 3. The bottom of the pressing frame 5 is fixedly connected to the top of the pressure sensor 6. A slide rail 14 is fixedly installed inside the worktable 1. The slide rail 14 provides a movement track for the steel mold box 8, restricting the movement direction of the steel mold box 8 and ensuring that the steel mold box 8 can accurately move to the designated position in the horizontal direction. When the steel mold box 8 is pushed by the push plate 17, it will slide along the slide rail 14. The slide rail 14 is "L" shaped, and the steel mold box 8 is slidably connected to it. A centering sensor 18 is fixedly installed on the top of the slide rail 14, near the side of the slide rail 14 close to the steel mold box 8, to detect whether the steel mold box 8 has reached the designated position and ensure that the steel mold box 8 is in the correct processing position in the horizontal direction. A cover plate 15 is hinged to one side of the worktable 1. A telescopic rod 16 is fixedly installed on the side of the cover plate 15 close to the worktable 1. A push plate 17 is fixedly installed on the end of the telescopic rod 16 away from the cover plate 15. The side of the push plate 17 away from the telescopic rod 16 cooperates with the steel mold box 8. When the telescopic rod 16 extends or retracts, the push plate 17 will transmit force to the steel mold box 8, causing the steel mold box 8 to move.

[0032] The working process of this utility model:

[0033] Step 1: After everything is installed, pour the raw material into the steel mold box 8. The motor 13 drives the threaded rod 12 to rotate, and the threaded block 11 moves along the threaded rod 12, which drives the telescopic frame 10 to extend and retract. The pallet 9 then rises and falls to the appropriate height, so that the bottom protrusion of the steel mold box 8 matches the top fitting groove of the pallet 9, completing the height positioning of the steel mold box 8. At the same time, the centering sensor 18 detects the position of the steel mold box 8 to ensure that it is accurately in the processing position in the horizontal direction. At this point, the telescopic frame 10 controls the pallet 9 to raise and lower the steel mold box 8 to the position where it needs to be pressed.

[0034] Step 2: Cylinder 4 is activated, pushing the pressing frame 5 down. Pressure sensor 6 monitors the pressure in real time to ensure that the pressing force is appropriate and to complete precise pressing.

[0035] Step 3: After pressing is completed, the telescopic frame 10 descends, and the steel mold box 8 falls exactly into the position of the slide rail 14. At this time, the telescopic rod 16 extends and pushes the push plate 17. The push plate 17 transmits force to the steel mold box 8, and the steel mold box 8 slides along the slide rail 14 to the discharge point on one side of the worktable 1, preparing for subsequent processing.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
