Description

Technical Field

[0001] This utility model relates to the field of asphalt viscosity testing technology, specifically to a novel emulsified asphalt standard viscosity testing device. Background Technology

[0002] The emulsified asphalt viscosity testing device is a specialized instrument for testing the viscosity of emulsified asphalt. Emulsified asphalt is a liquid asphalt produced by asphalt and emulsifiers under certain processing conditions. It has the characteristics of low viscosity and good fluidity at room temperature and is widely used in the field of road construction materials, such as interlayer bonding oil for asphalt pavement. Viscosity is an important performance indicator of emulsified asphalt, which directly affects its performance and construction quality. Viscosity testing can ensure that emulsified asphalt meets engineering requirements, thereby guaranteeing project quality.

[0003] Existing asphalt viscosity testing devices are usually equipped with only a single workbench or measuring cup. After each test, preparation steps such as cleaning and replacing the measuring cup are required, which leads to an extended testing cycle.

[0004] For example, the asphalt standard viscosity testing device disclosed in the patent with authorization announcement number CN219657428U is equipped with only a single testing component (viscosity cup + measuring cylinder), and relies only on the result of a single test. There is no mechanism for repeated verification or comparison. Therefore, after each test, it is necessary to wait for the measuring cup to be cleaned. It is impossible to prepare the measuring cup and test in parallel. In high-frequency testing scenarios (such as rapid quality inspection at engineering sites), it cannot meet the timeliness requirements and reduces the overall work efficiency.

[0005] Therefore, it is necessary to invent a new type of standard viscosity testing device for emulsified asphalt to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a novel device for testing the standard viscosity of emulsified asphalt, in order to solve the problems in the technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel emulsified asphalt standard viscosity testing device, comprising a frame, a heating chamber disposed above the frame, a support plate disposed inside the heating chamber, a sample container disposed on the support plate, a first workbench and a second workbench disposed above the frame, a sliding sleeve disposed at the center of the bottom of each of the first and second workbenches, a reciprocating screw passing through the interior of the sliding sleeve, the thread on the outer wall of the reciprocating screw engaging with the thread on the inner wall of the sliding sleeve, a motor disposed at one end of the frame, the output end of the motor being connected to the reciprocating screw, a measuring cup disposed at the center of the table surface of the first and second workbenches, and a timer disposed on the front side above the first and second workbenches.

[0008] Preferably, the sample container is provided with a sealing cap at the top and a transparent dropper is connected to the bottom of the sample container. The transparent dropper is provided with a switch valve, and the flow rate of the transparent dropper is adjusted by the switch valve to ensure that the sample is dripped into the measuring cup at a constant rate.

[0009] Preferably, heating wires are provided on the left and right sides of the inner wall of the heating box, and heaters are provided on the left and right sides of the outer wall of the heating box. The heating wires and heaters are connected by wires, and the heating wires provide a uniform heat source; the heaters are powered by wires to realize energy conversion.

[0010] Preferably, a temperature sensor is provided at one end of the inner wall of the heating chamber, and a temperature controller is provided at one end of the outer wall of the heating chamber. A display is provided on one side of the temperature controller and located on the front wall of the heating chamber. A relay is provided on the other side of the temperature controller. The relay is connected to the heater through a wire to monitor and control the temperature inside the heating chamber in real time, so as to prevent overheating or temperature fluctuations from affecting the test results.

[0011] Preferably, both sides of the bottom surface of the first and second workbenches are provided with slides, and a slide table is slidably provided below the slides and located on the frame, so as to realize the smooth movement of the first and second workbenches and ensure the precise alignment between the sample container and the measuring cup.

[0012] Preferably, the measuring cup is made of transparent material and has graduation lines on its outer wall. The transparent material facilitates observation of the sample dripping process and volume change, while the graduation lines provide a volume reference and reduce reading errors.

[0013] Preferably, upright plates are provided on the left and right sides above the No. 1 and No. 2 workbenches, and hand-tightening screws are threaded through the upright plates. The fine threads on the outer wall of the hand-tightening screws cooperate with the fine threads on the inner wall of the upright plates, so as to realize the precise movement of the clamping block through the thread transmission and meet the clamping and positioning requirements of the measuring cup.

[0014] Preferably, one end of the hand-tightening screw is provided with a clamping block, the groove of the clamping block is provided with a silicone pad, the side wall of the clamping block is provided with a guide rod that slides through to the upright plate, the silicone pad provides a flexible contact surface to protect the surface of the measuring cup and prevent scratches or deformation during clamping, while increasing friction to ensure clamping stability.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. This utility model uses a reciprocating screw to drive a sliding sleeve to move the workbench horizontally, enabling rapid switching between workbench 1 and workbench 2. By alternating between workbench 1 and workbench 2, two emulsified asphalt viscosity tests can be completed within the same testing cycle. The results of the two tests can be mutually verified, reducing the random errors that may exist in a single test and improving data reliability. Furthermore, when workbench 1 performs the first test, workbench 2 can simultaneously clean the measuring cup, avoiding the waiting time of a single test in traditional devices and significantly improving testing efficiency.

[0017] 2. This utility model achieves the clamping and positioning of the measuring cup by the fine thread engagement of the hand screw and the sliding sleeve. The synergistic effect of the clamp and the sliding sleeve reduces the offset or tilt of the measuring cup during the movement of the workbench, ensuring that the dripping point is always located at the center of the cup mouth, reducing the deviation of the dripping position caused by shaking, and suppressing the disturbance of external vibration to the liquid sample, thereby improving the consistency of the test data.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-6 The novel emulsified asphalt standard viscosity testing device shown includes a frame 1, a heating chamber 2 mounted above the frame 1, a support plate 3 inside the heating chamber 2, a sample container 4 mounted on the support plate 3, a sealed cap on the top of the sample container 4, and a transparent dropper 11 connected to the bottom of the sample container 4. A switch valve 12 is mounted on the transparent dropper 11. A first workbench 13 and a second workbench 14 are mounted above the frame 1. A sliding sleeve 15 is mounted at the center of the bottom of both the first workbench 13 and the second workbench 14. A reciprocating screw 17 passes through the interior of the sliding sleeve 15. The threads on the outer wall of the 7 sleeve 15 are engaged with the threads on the inner wall of the sliding sleeve 15. A motor 18 is installed at one end of the upper part of the frame 1. The output end of the motor 18 is connected to the reciprocating screw 17. Slides 16 are installed on both sides of the bottom surface of the first workbench 13 and the second workbench 14. A slide table 19 is slidably installed below the slide table 16 and located on the frame 1. A measuring cup 20 is installed at the center of the table surface of the first workbench 13 and the second workbench 14. The measuring cup 20 is made of transparent material and has scale lines on its outer wall. A timer 25 is installed on the front side above the first workbench 13 and the second workbench 14.

[0028] In this embodiment, the threaded engagement between the reciprocating lead screw 17 and the sliding sleeve 15 enables precise alternating movement of the first workbench 13 and the second workbench 14. The motor 18 provides power, and the sliding structure of the slide block 16 and the slide table 19 restricts the degrees of freedom of the workbench, ensuring movement stability. The motor 18 drives the workbench, replacing manual adjustment, reducing human error and improving operational consistency. By using the two workbench alternately, the second workbench 14 can simultaneously prepare to clean the measuring cup 20 while the first workbench 13 is performing the test, reducing waiting time. Therefore, the results of the two tests can be mutually verified, reducing random errors in a single test and improving data reliability.

[0029] Heating wires 5 are installed on the left and right sides of the inner wall of the heating chamber 2, and heaters 6 are installed on the left and right sides of the outer wall of the heating chamber 2. The heating wires 5 and heaters 6 are connected by wires. A temperature sensor 7 is installed at one end of the inner wall of the heating chamber 2, and a thermostat 8 is installed at one end of the outer wall of the heating chamber 2. A display 9 is installed on one side of the thermostat 8 and is located on the front wall of the outer side of the heating chamber 2. A relay 10 is installed on the other side of the thermostat 8. The relay 10 is connected to the heater 6 by wires.

[0030] In this implementation, the dual-sided heaters 6 provide backup heating capability. If one side fails, the other side can still maintain basic heating function, improving equipment reliability. Temperature sensor 7 monitors the temperature of the hot water inside heating chamber 2 in real time, and temperature controller 8 automatically adjusts the power of heater 6 according to the set value to achieve precise temperature control. Display 9 displays the current temperature intuitively, making it easy for operators to monitor the heating status. Relay 10 quickly switches the power supply of heater 6 according to the signal from temperature controller 8. By adjusting the output voltage or current of heater 6, the heating power of heating wire 5 can be changed to adapt to the heating requirements of different asphalt samples, such as high-temperature rapid heating or low-temperature slow heating. Therefore, the closed-loop control of temperature sensor 7 and temperature controller 8 ensures that the temperature inside heating chamber 2 is stable at the set value, meeting the accuracy requirements for heating asphalt samples.

[0031] On the left and right sides above the No. 1 workbench 13 and the No. 2 workbench 14, there are upright plates 21. A hand-tightening screw 22 passes through the upright plate 21. The fine thread on the outer wall of the hand-tightening screw 22 matches the fine thread on the inner wall of the upright plate 21. A clamping block 23 is provided at one end of the hand-tightening screw 22. A silicone pad is provided in the groove of the clamping block 23. A guide rod 24 is provided on the side wall of the clamping block 23 and slides through to the upright plate 21.

[0032] In this embodiment, upright plates 21 and clamping blocks 23 are provided on the left and right sides above the first workbench 13 and the second workbench 14, forming a symmetrical clamping structure. The double-sided clamping ensures that the measuring cup 20 is subjected to uniform force, preventing deformation or tilting caused by single-sided clamping. The clamped measuring cup 20 ensures stability and accuracy during the movement and testing process of the first workbench 13 or the second workbench 14, ensuring that the measuring cup 20 always remains vertical during the movement of the first workbench 13 or the second workbench 14, avoiding liquid sample splashing or drop point deviation due to tilting. In addition, the fine thread and the guide rod 24 provide self-locking capability to prevent the clamping block 23 from loosening under vibration or external force, ensuring that the measuring cup 20 always maintains a stable clamping state during long-term testing.

[0033] Working principle of this utility model:

[0034] Refer to the instruction manual appendix Figure 1-6 When using this utility model, firstly, pour the emulsified asphalt sample to be tested into the sample container 4, cover the top sealing cap, set the target temperature (e.g., 60℃) through the display instrument 9, start the heater 6, the temperature sensor 7 monitors the temperature in real time, and the temperature controller 8 automatically adjusts the power of the heater 6 until the temperature stabilizes at the set value. Keep the sample container 4 heated to the target temperature in the heating box 2 to ensure that the asphalt sample is heated evenly. Then, place the transparent measuring cup 20 in the center of the table surface of workbench 13 or workbench 14, ensuring that the scale lines are clearly visible. Rotate the hand screws 22 on both sides to drive the clamping block 23 to move towards the center through the fine thread, clamping the outer wall of the measuring cup 20, and the silicone pad adheres to the surface of the measuring cup 20.

[0035] Then, start the motor 18 to drive the reciprocating screw 17 to rotate. The sliding sleeve 15 drives the first platform 13 or the second platform 14 to move horizontally along the slide table 19 to the starting position of the test. When the sliding sleeve 15 reaches the unthreaded section of the reciprocating screw 17, the motor 18 can be turned off. At this time, the measuring cup 20 on the first platform 13 or the second platform 14 is aligned with the transparent dropper 11. Then, open the switch valve 12 of the transparent dropper 11 to allow the heated asphalt sample to drip slowly into the measuring cup 20. When the asphalt drips to the scale line of the measuring cup 20, such as 50mL, immediately start the timer 25 to record the time it takes for the asphalt to drip from the scale line to the bottom of the measuring cup 20. Repeat the measurement 3 times and take the average value. When the first platform 13 is testing, the second platform 14 is simultaneously preparing to clean the measuring cup 20 to reduce the waiting time. The second platform 14 is quickly switched by the motor 18 to realize mutual verification of the two test results and reduce random errors.
