Description

Technical Field

[0001] The utility model relates to the technical field of asphalt test auxiliary equipment, in particular to an asphalt dynamic viscosity test auxiliary device. Background Art

[0002] Viscosity is a physical quantity that characterizes the inherent characteristics of a fluid. In road engineering, dynamic viscosity is the most ideal indicator of asphalt's heat resistance in midsummer. At the same time, the temperature that needs to be controlled during mixing and construction can also be obtained through dynamic viscosity. Therefore, dynamic viscosity is an important parameter in asphalt quality control.

[0003] After searching, the authorized Chinese patent announcement number CN 217466578 U discloses a mold auxiliary device for an asphalt dynamic viscosity tester, including a main cylinder and a vertical cylinder. The lower ends of the main cylinder and the vertical cylinder are fixedly connected through a bend pipe, a capillary pad is fixedly connected to the inner upper part of the inner side of the vertical cylinder, and a protective component is installed on the inner side of the outer wall of the main cylinder and the vertical cylinder. The main cylinder scale and the vertical cylinder scale designed in this case can be directly marked and glued to the inner glass, which is convenient and quick, so that the cylinder measurement can be more accurate, avoiding the need for traditional molds to continuously replenish asphalt and repeatedly mold to achieve the exact required amount, resulting in test efficiency problems.

[0004] The asphalt testing equipment in the above patent still has certain shortcomings. Since the existing asphalt itself has a certain viscosity, and the asphalt will gradually cool down during the test, the internal fluidity of the asphalt becomes worse and worse as the temperature decreases. It is easy to stick to the wall of the test tube and is difficult to clean quickly, which will have a certain impact on subsequent continuous tests and is often inconvenient to use. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an auxiliary device for an asphalt dynamic viscosity test, which solves the problem that the existing asphalt itself has a certain viscosity and the asphalt will gradually cool down during the test. As the temperature decreases, the internal fluidity of the asphalt becomes worse and worse, and it is easy to stick to the wall of the test tube and is difficult to clean quickly, which will have a certain impact on subsequent continuous tests and is often inconvenient to use.

[0006] The utility model provides the following technical solutions: an auxiliary device for asphalt dynamic viscosity test, comprising an asphalt dynamic viscosity tester, wherein an upper control console is arranged at the top of the asphalt dynamic viscosity tester, a side test chamber is arranged at the side of the asphalt dynamic viscosity tester, an asphalt storage cylinder is arranged in the side test chamber, an anti-asphalt sticking film is arranged on the inner wall of the asphalt storage cylinder, and the asphalt storage cylinder is fixedly connected to the anti-asphalt sticking film through a sticking film disassembly component arranged in the asphalt storage cylinder;

[0007] The sticky film removable assembly includes a bottom support plate arranged at the bottom end of the asphalt storage cylinder, two sticky film fixing plates are symmetrically arranged at the bottom of the anti-asphalt sticky film, and two bottom plug holes are symmetrically opened at the bottom end of the asphalt storage cylinder. A connecting screw is vertically arranged at the bottom end of the sticky film fixing plate, and the connecting screw passes through the anti-asphalt sticky film, the bottom plug hole and extends to the bottom of the bottom support plate. A connecting nut is sleeved on the bottom end of the connecting screw.

[0008] Preferred technical solution 1: Two driving grooves are symmetrically provided on the upper control console, and a rotating screw hole is provided at the top of the driving groove.

[0009] Preferred technical solution 2: A rotating screw rod is rotatably arranged in the rotating screw hole, and a resisting connecting plate is rotatably arranged at the bottom end of the rotating screw rod.

[0010] Preferred technical solution three: two sliding blocks are symmetrically arranged at the bottom end of the bottom support plate, and two sliding grooves are symmetrically opened at the bottom end of the side test bin, and the sliding blocks are slidably inserted in the sliding grooves.

[0011] This solution can make the asphalt storage cylinder on the bottom support plate slide out from the side test chamber more conveniently.

[0012] Preferred technical solution four: A connecting block is provided at the top end of the rotating screw rod for facilitating rotation.

[0013] This solution can make it more convenient for users to rotate the rotating screw.

[0014] Preferred technical solution five: A rubber pad is provided at the bottom end of the resisting connecting plate to facilitate the resisting of the anti-asphalt sticky film.

[0015] This solution can make the resistance connecting plate resist the anti-asphalt sticking film more firmly under the push of the rotating screw.

[0016] Compared with the prior art, the utility model provides an auxiliary device for asphalt dynamic viscosity test, which has the following beneficial effects:

[0017] (1) The utility model provides an anti-asphalt sticky film on the inner wall of the asphalt storage cylinder, and fixes the anti-asphalt sticky film to the inner wall of the asphalt storage cylinder through the disassembly assembly of the sticky film. Therefore, when adding test asphalt into the asphalt storage cylinder, the asphalt will no longer stick to the inner wall of the asphalt storage cylinder due to the increase of viscosity caused by the decrease of temperature of the asphalt. After the asphalt test is completed, the user can remove the anti-asphalt sticky film on the inner wall of the asphalt storage cylinder. The anti-sticky property of the anti-asphalt sticky film can also be quickly removed to facilitate the quick cleaning work during the asphalt test, greatly improve the convenience of the user for subsequent continuous testing, and make it more convenient to use.

[0025] See also Figure 1-4

[0026] Embodiment 1: An auxiliary device for asphalt dynamic viscosity test, comprising an asphalt dynamic viscosity tester 1, an upper control console 2 is arranged at the top of the asphalt dynamic viscosity tester 1, a side test chamber 3 is arranged at the side of the asphalt dynamic viscosity tester 1, an asphalt storage cylinder 4 is arranged in the side test chamber 3, an anti-asphalt sticky film 5 is arranged on the inner wall of the asphalt storage cylinder 4, and the asphalt storage cylinder 4 is fixedly connected to the anti-asphalt sticky film 5 through a sticky film disassembly component 6 arranged in the asphalt storage cylinder 4.

[0027] The adhesive film removable component 6 includes a bottom support plate 601 arranged at the bottom end of the asphalt storage cylinder 4, two adhesive film fixing plates 602 are symmetrically arranged at the bottom of the anti-asphalt adhesive film 5, and two bottom sockets 603 are symmetrically opened at the bottom end of the asphalt storage cylinder 4. A connecting screw 604 is vertically arranged at the bottom end of the adhesive film fixing plate 602, and the connecting screw 604 passes through the anti-asphalt adhesive film 5, the bottom socket 603 and extends to the bottom of the bottom support plate 601.

[0028] The bottom end of the connecting screw 604 is sleeved with a connecting nut 605, and two driving grooves 606 are symmetrically provided on the upper control console 2. A rotating screw hole 607 is provided at the top of the driving groove 606, and a rotating screw 608 is rotatably provided in the rotating screw hole 607. The bottom end of the rotating screw 608 is rotatably provided with a resisting connecting plate 609.

[0029] Embodiment 2: The difference between this embodiment and embodiment 1 is that two sliding blocks are symmetrically arranged at the bottom end of the bottom support plate 601, and two sliding grooves are symmetrically opened at the bottom end of the side test chamber 3, and the sliding blocks are slidably inserted in the sliding grooves.

[0030] This allows the asphalt storage cylinder 4 on the bottom support plate 601 to slide out of the side test chamber 3 more conveniently.

[0031] Embodiment 3: The difference between this embodiment and embodiment 1 is that a connecting block is provided at the top of the rotating screw rod 608 for facilitating rotation.

[0032] This makes it more convenient for the user to rotate the screw 608.

[0033] Embodiment 4: The difference between this embodiment and embodiment 1 is that a rubber pad is provided at the bottom end of the resisting connecting plate 609 to facilitate the resisting of the anti-asphalt sticky membrane 5 .

[0034] This makes the resisting connecting plate 609 more firmly resist the anti-asphalt sticking film 5 under the push of the rotating screw 608.

[0035] In this embodiment, since the existing asphalt itself has a certain viscosity, and the asphalt will gradually cool down during the test, the internal fluidity of the asphalt will become worse and worse as the temperature decreases, and it will eventually easily stick to the wall of the test tube and be difficult to clean quickly, which will have a certain impact on subsequent continuous tests and is often inconvenient to use.

[0036] In summary, in specific implementation, when the user needs to add asphalt to be tested into the asphalt storage cylinder 4, the user can first lay the anti-asphalt sticky film 5 in the asphalt storage cylinder 4, so that the anti-asphalt sticky film 5 is completely fitted with the inner wall of the asphalt storage cylinder 4, and then, by inserting the connecting screw 604 into the bottom end of the asphalt storage cylinder 4, the sticky film fixing plate 602 is in contact with the anti-asphalt sticky film 5 and the asphalt storage cylinder 4, and the bottom end of the connecting screw 604 extends to below the bottom support plate 601, and a connecting nut 605 is sleeved on the connecting screw 604, so that the anti-asphalt sticky film 5 and the bottom wall of the asphalt storage cylinder 4 are tightly fitted through the contact of the sticky film fixing plate 602.

[0037] As for the top edge of the asphalt storage cylinder 4, the user rotates the rotating screw 608 so that the rotating screw 608 pushes the abutting connecting plate 609 to abut and fix the anti-asphalt sticky film 5 located on the top edge of the asphalt storage cylinder 4, so that the anti-asphalt sticky film 5 can be completely attached to the asphalt storage cylinder 4. When the asphalt required for the test is added into the asphalt storage cylinder 4, the asphalt will be separated from the inner wall of the asphalt storage cylinder 4 by the anti-asphalt sticky film 5.

[0038] This prevents the asphalt from sticking to the inner wall of the asphalt storage tube 4 after the test and making it difficult to clean. In addition, due to the anti-adhesion property of the anti-asphalt film 5, the test asphalt remaining on the anti-asphalt film 5 can be quickly removed, thereby facilitating the rapid cleaning work during the asphalt test, greatly improving the user's convenience for subsequent continuous testing, and making it more convenient to use.
