[0001] The utility model relates to the technical field of asphalt performance detection equipment, in particular to a modified asphalt viscosity detection device. Background Technique

[0002] Modified asphalt is an asphalt binder made by adding external admixtures such as rubber, resin, polymer or other fillers, or by taking measures such as mild oxidation processing of asphalt, which can improve the performance of asphalt or asphalt mixture. After modification, modified asphalt has the advantages of high temperature resistance, low temperature resistance, strong adaptability; good toughness, fatigue resistance, and increased pavement bearing capacity; resistance to water, oil and ultraviolet radiation, and aging delay; stable performance, long service life, and reduced maintenance costs. It has good practicability and is therefore widely used in the construction of highway engineering and waterproof engineering.

[0021] Such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, the technical solution adopted by the present utility model is as follows: A modified asphalt viscosity detection device provided by this solution includes a base, a heating cup 2, a clamping assembly 3, an adjusting assembly 4, and a rotational viscometer 5. A frame 1 is provided on the base. The clamping assembly 3 is arranged on the base and located inside the frame 1. The heating cup 2 is snap-fitted on the clamping assembly 3. The adjusting assembly 4 is arranged on both sides inside the frame 1. The rotational viscometer 5 is installed on the adjusting assembly 4, and the rotational viscometer 5 corresponds to the heating cup 2. The clamping assembly 3 includes an adjusting cavity 6 and a bidirectional lead screw 7. The adjusting cavity 6 is rotatably arranged in the middle of the upper part of the base. A driving motor 8 is provided at the bottom of the base. The output shaft of the driving motor 8 is connected to the middle of the lower part of the adjusting cavity 6. The bidirectional lead screw 7 is rotatably arranged between the inner side walls of the adjusting cavity 6. Threaded seats 9 are threadedly connected to both ends of the bidirectional lead screw 7. A clamping plate 10 is provided at the upper end of the threaded seat 9. A guiding groove 11 for guiding and limiting the clamping plate 10 is provided at the upper end of the adjusting cavity 6. The clamping plate 10 passes through the guiding groove 11 and extends above the adjusting cavity 6. The adjusting assembly 4 includes a threaded rod 12 and a forward and reverse motor 13. The threaded rod 12 is rotatably arranged on one side of the frame 1. The forward and reverse motor 13 is arranged on the frame 1. The output shaft of the forward and reverse motor 13 is connected to one end of the threaded rod 12. A height adjusting frame 14 is threadedly connected to the threaded rod 12.
