[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.
[0023] like Figure 1 and Figure 2 As shown, the asphalt penetration test device of this utility model includes a penetration meter 1, a constant temperature controller 2, a constant temperature container 3, and a sample transfer device 4 located in the constant temperature container 3;
[0024] The penetration tester 1 is used to detect, penetrate and read the penetration of the asphalt sample. The constant temperature controller 2 is connected to the constant temperature container 3 and is used to keep the asphalt sample in the constant temperature container 3 at a constant temperature.
[0025] The sample transfer device 4 includes a rotating device 41 located in the middle and a plurality of moving devices 42 located outside the rotating device 41. The moving device 42 includes a sliding channel 421 and a sample container 422. The sliding channel 421 and the sample container 422 are slidably connected. The sample container 422 is used to hold the asphalt sample. The rotating device 41 is used to fix and rotate the sample container 422.
[0026] This utility model of asphalt penetration testing device improves the efficiency and accuracy of asphalt sample penetration testing by integrating the penetration meter 1, the constant temperature controller 2, the constant temperature container 3, and the sample transfer device 4, and reduces the tediousness and potential errors of manual operation.
[0027] To determine the starting point for calculating the needle penetration time, the penetration meter 1 is equipped with an infrared detector 11 and a standard needle 12. The infrared detector 11 is used to detect the distance between the tip of the standard needle 12 and the asphalt sample. The non-contact measurement of the infrared detector 11 in the penetration meter 1 reduces interference with the asphalt sample and improves the accuracy of the measurement results.
[0028] Preferably, the thermostat 2 is a thermostat water bath controller, and the thermostat 2 is connected to the thermostat container 3 via a connecting pipe 5, so that the thermostat 2 controls the water bath temperature inside the thermostat container 3. By precisely controlling the water bath temperature, a stable testing environment is provided for the asphalt sample, ensuring the consistency and reliability of the test results.
[0029] More preferably, to achieve water circulation and better control the water temperature, two connecting pipes 5 are provided, with their ends connected to the bottom sidewall of the thermostat 2 and the bottom sidewall of the thermostat container 3, respectively. The design of two connecting pipes 5 allows the thermostat 2 to uniformly control the water bath temperature within the thermostat container 3, improving the efficiency and uniformity of temperature control and ensuring the temperature stability of the asphalt sample.
[0030] Combination Figures 1-3 The specific structure of the sample transfer device 4 of the asphalt penetration test device of this utility model is described below:
[0031] The rotating device 41 includes a rotating disk 411 and a rotating motor (not shown in the figure) for driving the rotating disk 411. The moving device 42 is located on the radial outer side of the rotating disk 411. There are 3 moving devices 42, and the included angle between adjacent moving devices 42 is 120°. The 3 moving devices 42 are evenly distributed, which makes the replacement of the asphalt sample more efficient.
[0032] To facilitate the loading and unloading of the asphalt samples, the sample container 422 includes a sliding ring 422a slidably connected to the sliding channel 421 and a sample dish 422b disposed above and inside the sliding ring 422a. The sliding ring 422a and the sample dish 422b are detachably connected. The detachable connection design of the sliding ring 422a and the sample dish 422b in the sample container 422 improves the convenience of replacing the asphalt samples and also facilitates the cleaning and maintenance of the sample dish 422b, ensuring the cleanliness of the testing environment.
[0033] Furthermore, in order to make the connection between the sample container 422 and the sliding track 421 more stable, the top surface of the sliding track 421 is provided with sliding rails 421a on both sides, and two sliding blocks 422c adapted to the sliding rails 421a are provided below the sliding ring 422a.
[0034] The sliding block 422c is placed in the sliding track 421a so that the sliding ring 422a is connected to the sliding channel 421. The design of the sliding track 421a on the top surface of the sliding channel 421 and the sliding block 422c below the sliding ring 422a ensures the stability and accuracy of the sample dish 422b during movement, and improves the movement efficiency.
[0035] Specifically, the included angle ∠ between the centers C of the two sliding blocks 422c and the sliding ring 422a is...
[0036] A = 120°.
[0037] The rotating disk 411 and the sliding track 421 are each provided with a latching part 411a that is adapted to the sliding block 422c, so that the sliding block 422c is latched to the latching part 411a, thereby fixing the sample container 422 above the rotating disk 411. The design of the latching part 411a at the connection between the rotating disk 411 and the sliding track 421 can quickly fix and release the sample container 422, so as to rotate and change the test points of the asphalt sample and ensure the stability of the asphalt sample during the testing process.
[0038] Specifically, the two latching parts 411a are connected to the center C' of the rotating disk 411 at an angle ∠B = 120°, so as to correspond to ∠A.
[0039] It should be noted that there are 3 moving devices 42. The included angles between adjacent moving devices 42 are 120°, ∠A = 120° and ∠B = 120°, which ensures that the sample container 422 returns to its initial position after the rotating disk 411 rotates 120° three times.
[0040] In actual use, the sample container 422 can be manually pushed along the sliding track 421 into the rotating disk 411, or a push rod, a robotic arm, etc. can be added to realize the automated movement of the sample container 422 along the sliding track 421. The push rod, robotic arm, etc. are existing technologies and will not be described in detail here.
[0041] Combination Figures 1-5 This section describes the usage of the asphalt penetration testing device of this utility model:
[0042] Specifically, three sample containers 422b containing asphalt samples are first placed in a constant temperature container 3 and kept at a temperature for no less than 1.5 hours; the sample containers 422 enter the rotating disk 411 along the sliding track, the sliding block 422c is engaged in the buckle part 411a, and the detection head of the infrared detector 11 is aligned with the needle tip of the standard needle 12;
[0043] As the standard needle 12 descends, the infrared detector 11 is activated and automatically measures the gap between the tip of the standard needle 12 and the asphalt sample until the tip of the standard needle 12 just contacts point N on the surface of the asphalt sample, and the penetration test of point N of the asphalt sample begins. The standard needle 12 penetrates the asphalt sample and automatically stops after 5 seconds, and the penetration meter automatically reads the value.
[0044] Then, the rotating disk 411 drives the sample container 422 to rotate 120° clockwise, the standard needle 2 descends, the infrared detector 11 is turned on and automatically measures the gap between the tip of the standard needle 12 and the asphalt sample until the tip of the standard needle 12 just contacts point M on the surface of the asphalt sample, and the penetration test of point M of the asphalt sample begins. The standard needle 12 penetrates the asphalt sample and automatically stops after 5 seconds, and the penetration meter automatically reads the value.
[0045] Then, the rotating disk 411 drives the sample container 422 to rotate 120° clockwise, the standard needle 2 descends, the infrared detector 11 turns on and automatically measures the gap between the tip of the standard needle 12 and the asphalt sample until the tip of the standard needle 12 just contacts point L on the surface of the asphalt sample, and the penetration test of point L of the asphalt sample begins. The standard needle 12 penetrates the asphalt sample and automatically stops after 5 seconds, and the penetration meter automatically reads the value.
[0046] At this point, the penetration test at points N, M, and L of the first asphalt sample is completed. The sample container 422 is removed from the rotating disk 411 and moved back to its original position. The second asphalt sample is then moved to the rotating disk 411, and the above steps are repeated until the test of the third asphalt sample is completed.
[0047] In summary, this utility model's asphalt penetration testing device, by integrating the penetration meter 1, the thermostat 2, the thermostat container 3, and the sample transfer device 4, improves the efficiency and accuracy of asphalt sample penetration testing, and reduces the tediousness and potential errors of manual operation. Furthermore, the device further enhances testing efficiency and accuracy through the coordination between the rotating device 41 and the moving device 42 within the sample transfer device 4.
