Abstract

This application relates to the field of asphalt standard viscosity testing technology, specifically an asphalt standard viscosity testing device, including a testing instrument body. Electric telescopic rods are fixedly connected to both sides of the testing instrument body, and a support plate is fixedly connected to the output end of each electric telescopic rod. A placement groove is formed on one side of the testing instrument body, and guide rails are fixedly connected to the inner walls of both sides of the placement groove. This application utilizes guide rails, a moving plate, a clamping assembly, a sliding bar, and a limiting block. The moving plate can slide between a pair of guide rails via the sliding bar. The clamping assembly can clamp and fix the measuring cylinder at a specific position on the top of the moving plate.

Description

Technical Field

[0001] This application relates to the field of asphalt standard viscosity testing technology, and in particular to an asphalt standard viscosity testing device. Background Technology

[0002] Standard viscosity testing of asphalt is a core test for evaluating the flowability of asphalt. It quantifies the consistency of asphalt by measuring the time (in seconds) it takes for asphalt to flow through a specified orifice under specific temperature and pressure, providing crucial parameters for road construction. This test is primarily used to evaluate the flowability of asphalt at construction temperatures, distinguish the consistency differences between different grades of asphalt, and ensure that the material meets the requirements of paving, compaction, and other processes. It is applicable to viscous petroleum asphalt and coal tar pitch, but not to emulsified asphalt, modified asphalt, or other special types. The asphalt standard viscosity tester is the core equipment for this test, and its structural design directly affects the testing accuracy. The instrument mainly consists of a sample container, an orifice plate, an insulation jacket, and a constant temperature water bath. The orifice plate is available in three sizes: 3mm, 5mm, and 10mm, allowing for flexible selection based on asphalt consistency. The constant temperature water bath precisely controls the temperature (accuracy ±0.1℃) to ensure a stable testing environment. The sample container holds the asphalt sample and, in conjunction with the orifice plate, forms a standard flow path. During testing, the asphalt is first heated to a flowable state and air bubbles are removed. After being poured into the sample container, it is kept at a specified temperature for 30 minutes. The bitumen was then released, and the time it took for 50 mL (or 25 mL) to flow out was recorded.

[0003] In existing technologies, testing personnel typically place the measuring cylinder manually into the placement slot of the testing instrument. This can easily lead to cylinder misalignment, causing the cylinder to not align with the flow orifice. Asphalt flowing out tends to adhere to the inner wall of the measuring cylinder, resulting in a deviation between the actual collected volume and the standard value of 50mL or 25mL. The asphalt adhering to the wall is not included in the measurement, directly causing distortion of viscosity data. This deviation can mislead the judgment of asphalt consistency, affecting the selection of engineering materials and potentially creating hidden dangers in road construction quality. At the same time, the testing instrument is placed on a workbench and lacks height adjustment. When reading the measuring cylinder, the unsuitable height can cause the line of sight to be out of parallel with the scale, resulting in reading parallax. Long-term operation may also cause the testing personnel to bend over or look up, increasing fatigue and indirectly reducing the accuracy of the readings, thus affecting the reliability of the test results. Summary of the Invention

[0004] The purpose of this application is to provide an asphalt standard viscosity testing device to solve the problems existing in the prior art.

[0005] The asphalt standard viscosity testing device provided in this application adopts the following technical solution: it includes a testing instrument body, electric telescopic rods are fixedly connected to both sides of the testing instrument body, a support plate is fixedly connected to the output end of the electric telescopic rods, a placement groove is opened on one side of the testing instrument body, guide rails are fixedly connected to the inner walls on both sides of the placement groove, a moving plate is arranged between a pair of guide rails, a pair of clamping components are arranged on the top of the moving plate, and a measuring cylinder is arranged on the top of the moving plate.

[0006] By adopting the above technical solution, the clamping assembly can clamp and fix the measuring cylinder at a specific position on the top of the moving plate. When the moving plate stops in the placement slot, the measuring cylinder is precisely aligned with the flow hole, avoiding positional deviation when manually placed. The bottom of the support plate contacts the table surface. After the measuring cylinder is in place, the electric telescopic rod can be activated. The output end of the electric telescopic rod drives the support plate to descend relative to the detector body, allowing for flexible adjustment of the height of the detector body.

[0007] Preferably, the clamping assembly includes a mounting plate, which is fixedly connected to the top of the movable plate. A telescopic rod one and a pair of telescopic rods two are fixedly connected to one side of the mounting plate. A clamping block is fixedly connected to one end of the telescopic rod one. A spring is sleeved on the outer periphery of the telescopic rod one. One end of each of the telescopic rods two is fixedly connected to the clamping block.

[0008] By adopting the above technical solution, the measuring cylinder is placed on the top of the moving plate. The measuring cylinder is pushed and squeezed by the measuring cylinder, which forces a pair of clamping blocks to move away from each other. Both telescopic rod one and telescopic rod two retract, and the spring is compressed. When the measuring cylinder moves between a pair of clamping blocks, the spring pushes the corresponding clamping block, so that the measuring cylinder is clamped and fixed between a pair of clamping blocks.

[0009] Preferably, both sides of the movable plate are fixedly connected with sliding strips.

[0010] By adopting the above technical solution, the movable plate can slide between a pair of guide rails via a slider.

[0011] Preferably, the guide rail is provided with a sliding groove, which is adapted to the corresponding sliding bar.

[0012] By adopting the above technical solution, the slider can slide along the groove on the corresponding guide rail.

[0013] Preferably, a limiting groove is provided at the bottom of the movable plate.

[0014] By adopting the above technical solution, the limiting groove can restrict the movement range of the moving plate.

[0015] Preferably, a limiting block is fixedly connected to the bottom of the placement groove, and the limiting block is adapted to the limiting groove.

[0016] By adopting the above technical solution, as the moving plate moves, the side wall of the limiting groove at the bottom of the moving plate will contact the limiting block, thus restricting the position of the moving plate.

[0017] Preferably, a handle is fixedly connected to one side of the movable plate.

[0018] By adopting the above technical solution, the movable plate can be moved by using a handle.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. This application sets up a guide rail, a moving plate, a clamping assembly, a slide bar, and a limiting block. The moving plate can slide between a pair of guide rails via the slide bar. The clamping assembly can clamp and fix the measuring cylinder at a specific position on the top of the moving plate. As the moving plate moves, the side wall of the limiting groove at the bottom of the moving plate will contact the limiting block to restrict the position of the moving plate. This ensures that when the moving plate stops in the placement groove, the measuring cylinder is precisely aligned with the flow hole, avoiding positional deviation when manually placed, eliminating the problem of asphalt sticking to the wall when it flows out, ensuring accurate measurement of 50mL or 25mL, and improving the accuracy and repeatability of viscosity detection data. 2. This application incorporates an electric telescopic rod and a support plate. The bottom of the support plate contacts the table surface. Activating the electric telescopic rod causes the support plate to rise and fall relative to the instrument body. This allows for flexible adjustment of the instrument body's height, ensuring the graduated cylinder lines are aligned with the operator's line of sight, eliminating parallax, and guaranteeing accurate 25mL and 50mL measurements. Furthermore, it accommodates operators of varying heights, avoiding bending or tilting the head back, reducing fatigue, and improving the convenience and accuracy of readings.

[0022] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0023] An asphalt standard viscosity testing device includes a testing instrument body 1, electric telescopic rods 2 fixedly connected to both sides of the testing instrument body 1, a support plate 3 fixedly connected to the output end of the electric telescopic rods 2, a placement groove 4 opened on one side of the testing instrument body 1, guide rails 5 fixedly connected to the inner walls on both sides of the placement groove 4, a movable plate 6 arranged between a pair of guide rails 5, a pair of clamping components arranged on the top of the movable plate 6, a measuring cylinder 7 arranged on the top of the movable plate 6, and slide bars 13 fixedly connected to both sides of the movable plate 6. Slide grooves are opened on the guide rails 5, and the slide grooves are adapted to the corresponding slide bars 13. Specifically, the movable plate 6 can slide between a pair of guide rails 5 via the slider 13. The clamping assembly can clamp and fix the measuring cylinder 7 at a specific position on the top of the movable plate 6. When the movable plate 6 moves into the placement slot 4 and stops, the measuring cylinder 7 is precisely aligned with the flow hole, avoiding positional deviation when manually placed, eliminating the problem of asphalt sticking to the wall when flowing out, ensuring accurate measurement of 50mL or 25mL, and improving the accuracy and repeatability of viscosity test data. The bottom of the support plate 3 contacts the table surface. When the measuring cylinder 7 is in place, the electric telescopic rod 2 can be activated. The output end of the electric telescopic rod 2 drives the support plate 3 to descend relative to the instrument body 1, which can flexibly adjust the height of the instrument body 1 so that the scale line of the measuring cylinder 7 is level with the line of sight of the tester, eliminating reading parallax, ensuring accurate measurement of 25mL and 50mL, and at the same time, adapting to the operation of people of different heights, avoiding bending over or looking up, reducing fatigue, and improving the convenience and accuracy of reading.

[0024] The clamping assembly includes a mounting plate 8, which is fixedly connected to the top of the movable plate 6. A telescopic rod 9 and a pair of telescopic rods 10 are fixedly connected to one side of the mounting plate 8. A clamping block 11 is fixedly connected to one end of the telescopic rod 9. A spring 12 is sleeved on the outer periphery of the telescopic rod 9. One end of each telescopic rod 10 is fixedly connected to the clamping block 11. Specifically, the measuring cylinder 7 is placed on top of the moving plate 6, and the measuring cylinder 7 is pushed. The measuring cylinder 7 squeezes the clamping block 11, forcing the pair of clamping blocks 11 to move away from each other. The first telescopic rod 9 and the second telescopic rod 10 are both retracted, and the spring 12 is compressed. When the measuring cylinder 7 moves between the pair of clamping blocks 11, the spring 12 pushes the corresponding clamping block 11, so that the measuring cylinder 7 is clamped and fixed between the pair of clamping blocks 11.

[0025] A limiting groove is provided at the bottom of the movable plate 6, and a limiting block 14 is fixedly connected to the bottom of the placement groove 4. The limiting block 14 is adapted to the limiting groove, and a handle 15 is fixedly connected to one side of the movable plate 6. Specifically, the handle 15 can drive the moving plate 6 to move. As the moving plate 6 moves, the side wall of the limiting groove at the bottom of the moving plate 6 will contact the limiting block 14 to restrict the position of the moving plate 6. When the side wall of the limiting groove away from the handle 15 contacts the limiting block 14, the clamping component on the moving plate 6 is located outside the placement groove 4, which facilitates the loading and unloading of the measuring cylinder 7. When the limiting groove is close to the side wall of the handle 15 and contacts the limiting block 14, the measuring cylinder 7 is precisely aligned with the flow hole.

[0026] The working principle of this application is as follows: The movable plate 6 can be moved by the handle 15. The movable plate 6 can slide between a pair of guide rails 5 via the slide bar 13. As the movable plate 6 moves, the side wall of the limiting groove at the bottom of the movable plate 6 will contact the limiting block 14 to limit the position of the movable plate 6. When the side wall of the limiting groove away from the handle 15 contacts the limiting block 14, the clamping component on the movable plate 6 is located outside the placement groove 4, which facilitates loading and unloading of the measuring cylinder 7. First, place the measuring cylinder 7 on top of the moving plate 6, then push the measuring cylinder 7. The measuring cylinder 7 squeezes the clamping block 11, forcing the pair of clamping blocks 11 to move away from each other. The telescopic rod 1 9 and the telescopic rod 2 10 both retract, and the spring 12 is compressed. When the measuring cylinder 7 moves between the pair of clamping blocks 11, the spring 12 pushes the corresponding clamping block 11, so that the measuring cylinder 7 is clamped and fixed between the pair of clamping blocks 11. Then, by pushing the moving plate 6 with the handle 15, when the limiting groove is close to the side wall of the handle 15 and contacts the limiting block 14, the moving plate 6 moves into the placement groove 4 and stops. The measuring cylinder 7 is precisely aligned with the flow hole, avoiding the position deviation when manually placed, eliminating the problem of asphalt sticking to the wall when it flows out, ensuring accurate measurement of 50mL or 25mL, and improving the accuracy and repeatability of viscosity test data. The bottom of the support plate 3 contacts the table surface. After the measuring cylinder 7 is in place, the electric telescopic rod 2 can be activated. The output end of the electric telescopic rod 2 drives the support plate 3 to descend relative to the instrument body 1. The height of the instrument body 1 can be flexibly adjusted so that the scale line of the measuring cylinder 7 is level with the line of sight of the tester, eliminating reading parallax and ensuring accurate measurement of 25mL and 50mL. At the same time, it is suitable for people of different heights to operate, avoiding bending over or looking up, reducing fatigue, and improving the convenience and accuracy of reading.
