Description

Technical Field

[0001] This invention relates to the field of testing platforms, and in particular to a specimen testing platform suitable for testing the polishing value of coarse aggregates. Background Technology

[0002] In road engineering, the surface layer of asphalt pavement bears vehicle loads for a long time, and the asphalt film on the aggregate surface will gradually wear away. After the aggregate is exposed, it needs to provide its own anti-skid force. Therefore, the aggregate not only needs to have high wear resistance, but also good polishing resistance. Thus, a precise testing platform is needed to detect the polishing value of aggregate, provide a basis for the selection of road aggregate, and ensure safe driving. Previous coarse aggregate polishing value tests have shortcomings in specimen fixation and testing processes. For example, without a suitable fixing device, temporary tools are used to fix the specimen, resulting in the specimen not being firmly fixed, which affects the accuracy of the measurement results of the pendulum friction coefficient measuring instrument. Moreover, during the test, the specimen or pendulum instrument is prone to shaking, which will also cause deviations in the test data and cannot accurately reflect the polishing resistance of the aggregate.

[0003] A search revealed Chinese Patent Publication No. CN202770746U, which discloses a special testing platform for polished specimens. The platform includes a base plate with a specimen fixing groove and a specimen fixing top plate that clamps the specimen within the groove. The specimen to be tested is placed in the groove and fixed by the top plate. The base plate also has a leveling bolt fixing seat for a pendulum apparatus. This fixing seat ensures the position of the pendulum apparatus relative to the specimen fixing groove. A pendulum apparatus fixing clip on the base plate secures the apparatus, thus ensuring a firm installation of the specimen and the apparatus. However, this invention does not consider the need to level the platform before polishing. Failure to level the platform will result in uneven force during polishing, leading to a decrease in polishing accuracy. Summary of the Invention

[0004] To overcome the above deficiencies, this utility model provides a specimen testing platform suitable for coarse aggregate polishing value testing, aiming to improve the problem in the prior art that if the platform cannot be leveled, uneven force will occur during the polishing process, which will lead to a decrease in polishing accuracy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a test platform for a coarse aggregate polishing value test, comprising a test bench, wherein a leveling mechanism is provided inside the test bench for leveling the polishing platform, and a dust removal mechanism is provided on the front side of the test bench for cleaning and collecting the polished debris.

The rotating column is rotatably connected to the test bench, ensuring the flexibility and reliability of the leveling operation. The rotating plate plays a key supporting and adjusting role in the leveling process. The grinding plate is the core component of the grinding operation and directly affects the grinding effect. The speed reduction component is further equipped with a lifting component to accurately control the lifting and lowering of the grinding plate. The monitoring component can monitor various parameters in the grinding process in real time to ensure grinding quality.

[0007] As a further description of the above technical solution: The dust removal mechanism includes a collection box, the outer wall of which is slidably connected to the middle of the inner wall of the test bench. A handle is fixedly connected to the rear side of the collection box, and a hollow shell is fixedly connected to the front side of the collection box. A flexible hose is connected to the front side of the hollow shell. Connecting pipes are connected to the left and right ends of the front side of the test bench. A guide component is provided inside the collection box, and a dust collection component is provided inside the hollow shell.

[0008] Through the above technical solution: the collection box is slidably connected to the test platform to ensure smooth movement during use; the handle is easy for operators to hold and move the collection box; the hollow shell is connected to the hose to facilitate flexible connection of various equipment during dust removal; the connecting pipe ensures good sealing and connection stability during long-term use; the guiding component can accurately guide the flow of dust during dust removal to improve dust removal efficiency; and the dust suction component can quickly and effectively suck up and centrally process dust.

[0009] As a further description of the above technical solution: The power assembly includes multiple motors, the outer walls of which are fixedly connected to the left and right sides of the inner wall of the test bench. The output end of each motor is fixedly connected to a helical gear, the outer wall of which is meshed with a helical gear, and the inner wall of which is fixedly connected to a connecting column.

[0010] The above technical solution provides strong power output. The meshing connection between helical gear one and helical gear two ensures the smoothness and efficiency of power transmission. The connecting column plays a key supporting and connecting role, ensuring the stable operation of the entire leveling mechanism.

[0011] As a further description of the above technical solution: The speed reduction assembly includes two worm gears, the top ends of which are fixedly connected to the front and rear ends of the connecting column, and worm wheels are meshed with the outer walls of the worm gears.

[0012] The above technical solution ensures stability and reliability during transmission. The worm and worm wheel mesh with each other, thereby effectively transmitting power and achieving the deceleration function.

[0013] As a further description of the above technical solution: The lifting assembly includes a threaded rod, the bottom end of which is fixedly connected to the top of the worm gear, and a threaded shell is threadedly connected to the outer wall of the threaded rod.

[0014] The above technical solution ensures seamless power transmission. The threaded rod and threaded shell are connected, enabling the entire lifting assembly to perform lifting operations smoothly and steadily during operation, further improving the operational accuracy and stability of the entire system.

[0015] As a further description of the above technical solution: The monitoring component includes two hollow smooth shells. The bottoms of the two hollow smooth shells are fixedly connected to the front and rear sides of the top of the polishing plate. Smooth blocks are slidably connected to the inner walls of the hollow smooth shells, and a transparent plate is fixedly connected to the top of the inner walls of the hollow smooth shells.

[0016] The above technical solutions ensure that there will be no displacement during use, the smooth block can maintain good sliding performance during long-term use, and the transparent plate can not only clearly display the internal situation, but also effectively prevent dust from entering, thus ensuring the accuracy and reliability of monitoring data.

[0017] As a further description of the above technical solution: The guide assembly includes a triangular plate, the bottom of which is fixedly connected to the bottom of the inner wall of the collection box. Hollow grooves are provided on the top left and right sides of the outer wall of the collection box, and inclined plates are fixedly connected to the inner walls of the hollow grooves.

[0018] The above technical solution involves a triangular plate that is fixedly connected to the collection box to ensure that it will not shift during use, and an inclined plate that optimizes the material guiding effect.

[0019] As a further description of the above technical solution: The dust collection assembly includes a second motor, the outer wall of which is fixedly connected to the inner wall of the hollow shell, a fan is fixedly connected to the output end of the second motor, and a baffle is fixedly connected to the rear side of the inner wall of the hollow shell.

[0020] The above technical solutions ensure that the second motor remains stable even when running at high speed, the fan generates strong suction to effectively improve the dust collection effect, and the baffle effectively blocks large particles from entering, thereby extending the service life of the equipment and ensuring the smooth operation of the dust collection process.

[0021] In summary, This utility model has the following beneficial effects: 1. In this utility model, when grinding is required, the rotating plate is opened, and the smooth block is observed through the transparent plate to see if it is in the exact center of the hollow smooth shell. If it is off, motor one is started, which drives helical gear one and helical gear two to rotate. Helical gear two then drives the connecting column and worm to rotate. The worm and worm wheel cooperate to reduce the speed of motor one, so that the threaded rod rotates slowly. Because the threaded shell and the threaded rod are threadedly connected, when the threaded rod rotates, the threaded shell slowly moves up, lifting one side of the grinding plate and readjusting the smooth block to the center position. This achieves the leveling of the grinding plate, so that the object can be subjected to uniform force during the grinding process, thereby improving the grinding accuracy.

[0022] 2. In this utility model, when a large amount of waste is generated during grinding, the second motor is started to drive the fan to rotate. The fan sucks the waste along the hollow groove and falls onto the triangular plate under the guidance of the inclined plate. The inclined edge of the top surface of the triangular plate guides the waste to both sides to prevent accumulation and affect the collection efficiency. When the waste settles to the bottom, the hose is connected to the connecting pipe, and the sucked-in gas is sprayed out along the hose to blow up and collect the settled waste, thus realizing the collection and cleaning of waste and preventing the accumulation of waste from making it difficult to accurately control the thickness during grinding.

[0034] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The guide component 306 includes a triangular plate 3061, the bottom of which is fixedly connected to the bottom of the inner wall of the collection box 301. Hollow grooves 3063 are provided on the top left and right sides of the outer wall of the collection box 301. An inclined plate 3062 is fixedly connected to the inner wall of the hollow groove 3063.

The baffle 3073 can effectively block large particles from entering, thereby extending the service life of the equipment and ensuring the smooth operation of the dust collection process.

[0035] Working principle: When grinding is required, open the rotating plate 202 and observe through the transparent plate 2073 whether the smooth block 2072 is in the exact center of the hollow smooth shell 2071. If it deviates from the center, start motor one 2041. Motor one 2041 will drive helical gear one 2042 and helical gear two 2043 to rotate. During the rotation of helical gear two 2043, it will further drive the connecting column 2044 and worm gear 2051 to rotate. Worm gear 2051 and worm wheel 2052 are connected... The two mechanisms work together to reduce the speed of motor 2041, causing the threaded rod 2061 to rotate slowly. Since the threaded shell 2062 is threadedly connected to the threaded rod 2061, when the threaded rod 2061 rotates, the threaded shell 2062 will slowly move upward, and one side of the polishing plate 203 will be lifted. Therefore, the smooth block 2072 will be readjusted to the center position, achieving the leveling of the polishing plate 203. This ensures that the object is subjected to uniform force during the polishing process, thereby improving the polishing accuracy. During the grinding process, a large amount of waste debris is generated. At this time, the second motor 3071 is started, which drives the fan 3072 to rotate. The fan 3072 sucks in the generated waste debris along the hollow groove 3063 and falls onto the triangular plate 3061 under the guidance of the inclined plate 3062. The inclined edge of the top surface of the triangular plate 3061 guides the waste debris to both sides to prevent the waste debris from accumulating in the middle, thus affecting the collection efficiency. When the waste debris settles at the bottom, the hose 304 is connected to the connecting pipe 305. The sucked-in air will be sprayed out along the hose 304, thereby blowing up and recycling the waste debris that has settled at the bottom. This achieves the collection and cleaning of waste debris and prevents the accumulation of waste debris from making it difficult to accurately control the thickness during grinding.
