Description

Technical Field

[0001] The utility model relates to the technical field of asphalt concrete fluidity detection, in particular to an asphalt concrete fluidity detection device. Background Art

[0002] The fluidity of asphalt concrete is one of the important indicators of its construction and workability, and has a direct impact on the construction quality. Asphalt concrete with good fluidity is easy to spread and compact during the construction process, and can form a uniform and dense pavement structure, thereby improving the durability and performance of the pavement. Therefore, scientific evaluation of the fluidity of asphalt concrete is of great significance to ensuring construction quality. The Liuer fluidity test is a standardized test method that evaluates the fluidity of asphalt concrete by measuring the time it takes for a falling hammer to sink into asphalt concrete under specific conditions. This method has clear operating specifications and test steps, which can ensure the accuracy and comparability of the test results.

[0003] However, when using the existing Liuer fluidity test method to test asphalt concrete, the bracket design supporting the drop hammer is not stable enough, and it becomes loose during use, and cannot provide a stable falling track for the drop hammer. When the components are manually connected to each other, the drop hammer may not be placed correctly on the bracket, or it may be touched during the fall, causing it to deviate from the predetermined track. The drop hammer offset will cause inaccurate measurement time, thereby affecting the calculation results of Liuer fluidity. This will not truly reflect the fluidity of the asphalt mixture, misleading the subsequent construction and quality management, requiring re-testing or adjustment of the mix design, which will increase time and material costs and may delay the progress of the project.

One end of the heating wire 32 is electrically connected to one end of the electric heating block 39. The electric heater 31 is electrically connected to the controller 38.

When the fluidity is tested, the temperature of the devices involved in the test is the same as that of the asphalt concrete, thereby reducing the error of the test and ensuring the accuracy and reliability of the test data.

[0033] A detector 35 is fixedly connected to one side surface of the sliding groove 6. A detection window 36 is fixedly set on one side surface of the detector 35.

The motor 29 drives the threaded rod 30 at the output end to rotate, so as to control and change the height position of the triangular plate 28. An electromagnetic control end 33 is fixedly connected to the surface of one side of the triangular plate 28, and a reset electromagnetic block 27 is fixedly connected to the surface of one side of the electromagnetic control end 33.

[0035] Working principle: Please refer to Figure 1-Figure 5As shown, before using the utility model, the asphalt concrete to be tested is first introduced into the interior of the loading barrel 15 and injected into the lower end of the loading limit block 17, and the sliding plate 7 is used to slide upwards by using the sliding groove 6 and the sliding block 8 to place the loading barrel 15 loaded with materials in the placement groove of the base frame 1. After rotating it to a suitable angle, the sliding plate 7 is used to slide downwards by using the sliding groove 6 and the sliding block 8 to press the positioning frame 10 to the upper end of the loading barrel 15, so that the three main frames 11 are tightly buckled in the three positioning slots 16, the three sub-frames 12 are tightly buckled in the three positioning slots 16, and the one side surface of the connecting ring 13 is aligned with the one side surface of the loading barrel 15. The heating end 34 at one end of the loading barrel 15 is electrically connected to the controller 38 after being fitted and fixed by the buckle. The heating end 34 drives the heating layer 18 inside the loading barrel 15 to heat the asphalt concrete inside the loading barrel 15, so that it is always kept within the required test temperature range. The heat insulation layer 19 performs heat insulation treatment on it, which plays an effective protective role as a whole. After that, the controller 38 is used to control the electric heater 31 to work, so that the electric heating block 39 connected to the electric heater 31 through the electric heating wire 32 is heated, and the heat is transferred to the detection drop hammer 20 and the detection main rod 21, so as to ensure that when the fluidity is tested, the temperature of the devices involved in the test is the same as that of the asphalt concrete, thereby reducing the error of the test and ensuring the accuracy and reliability of the test data. Reliability, when it reaches the standard temperature required for the test, the controller 38 controls the electromagnetic control end 33 to disconnect the reset electromagnetic block 27 and the connecting iron core block 26, and separate them. The detection hammer 20 and the detection main rod 21 fall downward under their own weight. During the falling process, the detection main rod 21 is limited by the limiting ring 9 and the limiting ball 14, and the surface of the limiting ball 14 is relatively smooth, which can effectively reduce the friction generated when contacting the detection main rod 21, reduce the resistance component, and play a greater role in limiting, ensuring that the hammer falls vertically and prevents deviation, reducing the overall systematic error and random error caused by deviation, ensuring that the resistance it encounters when passing through the asphalt mixture is uniform and consistent, thereby more accurately reflecting the mixture. The fluidity of the mixed material is determined by scanning and recording the four coils through the detection window 36 of the detector 35 when it falls. At the same time, multi-level segmented data statistics and recording are used to improve the accuracy and reliability of the detection data. After the data is recorded, the motor 29 is used to drive the threaded rod 30 at the output end of the motor 29 to rotate, so that it drives the triangular plate 28 to move downward. When the connecting iron core block 26 and the reset electromagnetic block 27 are in contact with each other, the controller 38 controls the electromagnetic control end 33 to make the connecting iron core block 26 and the reset electromagnetic block 27 magnetically connected to each other, and the motor 29 is reversed to drive the triangular plate 28 and the detection component 4 to reset as a whole. After cleaning the whole, it is convenient for the next test to improve the overall practicality.
