Abstract
The invention discloses an asphalt ductility acquisition device. The asphalt ductility acquisition device comprises a test cabinet body, wherein a constant-temperature water bath is mounted in a cavity of the test cabinet body; a fixed clamp arranged on one side and a movable clamp capable of moving towards the other side relative to the fixed clamp are mounted in the cavity of the test cabinet body; the fixed clamp and the movable clamp are used for clamping asphalt samples; conductive particles are uniformly mixed in the asphalt samples; a detection circuit is formed after the asphalt samples are clamped by the fixed clamp and the movable clamp; a signal transmission circuit is arranged at one end of the detection circuit; a signal receiving circuit is arranged at the other end of the detection circuit. According to the asphalt ductility acquisition device, the breakage of the asphalt samples can be automatically judged according to the change of the received signal; a tester is capable of intelligently working, quickly responding when the asphalt sample is broken and accurately reading.
Description
Technical field
The present invention relates to a kind of pitch testing tool, be specially a kind of pitch ductility harvester.
Background technology
Pitch expansion test is one of important indicator of asphalt quality detection.Pitch ductility tester is the instrument for detecting pitch ductility, is applicable to the ductility measuring the materials such as road asphalt, eu-bitumen bottoms and Asphalt Emulsion Evaporation Residue.
Pitch ductility tester is by stretching to bitumen samples, and the stretching distance value obtained when being stretched to fracture can be used for the extension angle value analyzing bitumen samples.But whether traditional pitch ductility tester can only be observed bitumen samples by the mode of human eye and rupture, and test process is intelligent not, and test structure is not accurate enough.
Summary of the invention
In order to solve above technical matters, the invention provides a kind of test intellectuality, result pitch ductility harvester accurately.
The technical scheme that the present invention adopts for technical solution problem is:
Pitch ductility harvester, comprise test cabinet, the cavity of test cabinet is built with water bath with thermostatic control, test cabinet is provided with the fixed clip that is positioned at side and can moves folder towards opposite side displacement relative to this fixed clip in cavity, fixed clip and mobile folder are for clamping asphalt sample, evenly conducting particles is mixed with in asphalt sample, measure loop is formed after fixed clip and mobile folder clamping asphalt sample, one end of measure loop is provided with signal transmission circuit, and the other end is provided with signal receiving circuit.
The invention has the beneficial effects as follows: the present invention is mixed with conducting particles in asphalt sample, asphalt sample is made to become conductor, when asphalt sample is clamped between fixed clip and mobile folder, signal is sent in the side of asphalt sample, when asphalt sample does not rupture, signal can be delivered to opposite side and receive, when asphalt sample ruptures, signal transmission loop disconnects, opposite side does not receive corresponding signal, therefore just can automatic decision asphalt sample whether be ruptured by the change of Received signal strength, tester work is intelligent, can respond at once during asphalt sample fracture, accuracy of reading.
Accompanying drawing explanation
Be further detailed below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of an embodiment of the present invention.
Symbol description: 1-tests cabinet, 2-water bath with thermostatic control, 3-fixed clip, and 4-moves folder, 5-signal transmission circuit, 6-signal receiving circuit.
Embodiment
With reference to Fig. 1, ductility tester entirety of the present invention is a test cabinet 1, and its inside is provided with cavity.Cavity is built with water bath with thermostatic control 2.The fixed clip 3 that is positioned at side is installed in test cabinet 1 and folder 4 can be moved towards opposite side displacement relative to this fixed clip 3.Fixed clip 3 and mobile folder 4 are for clamping asphalt sample.
When specifically testing, be fixed at the two ends of asphalt sample on fixed clip 3 and mobile folder 4, then control mobile folder 4 and move, mobile folder 4 moves to and asphalt sample is ruptured, and the distance now moving folder 4 movement is the extension angle value of pitch.The speed of mobile folder 4 movement is fixing, and generally, when water bath with thermostatic control temperature is 25 DEG C, its translational speed is 5cm/min, and when water temperature is 15 DEG C, its draw speed is 1cm/min.
In order to the breaking state of asphalt sample automatically can be detected, evenly conducting particles is mixed with in asphalt sample, form measure loop after geometrical clamp 3 and mobile folder 4 clamp asphalt sample, one end of measure loop is provided with signal transmission circuit 5, and the other end is provided with signal receiving circuit 6.When asphalt sample does not rupture, signal transmission circuit 5 sends signal and can be delivered to opposite side and received circuit 6 receives, when asphalt sample ruptures, signal transmission loop disconnects, opposite side does not receive corresponding signal, therefore just can automatic decision asphalt sample whether be ruptured by the change of Received signal strength, tester work is intelligent, can respond at once during asphalt sample fracture, accuracy of reading.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
