Description
Technical field
The utility model relates to a kind of machine-shaping device of Marshall sample of Marshall Test, specifically the electronic compaction hammer mechanism hitting real machine of Marshall sample.
Background technology
Marshall Test is the test determining asphalt optimum oil-stone ratio.Its process of the test is to Marshall sample (asphalt) standard impact density under the conditions such as the temperature and humidity specified, the indexs such as the degree of stability of mensuration asphalt and flow valuve, after series of computation, draw out the relation curve of bitumen aggregate ratio and degree of stability, flow valuve, density, voidage, saturation degree respectively, finally determine the optimum oil-stone ratio of asphalt.
And electric compaction device is the shaping equipment of Marshall sample in Marshall Test.The electronic structure of hitting real machine of existing Marshall sample generally comprises organic frame, longitudinally-moving leads the compaction hammer guide rod be arranged in frame, straight skidding leads the compaction hammer be arranged on compaction hammer guide rod and the sample mold be arranged at below compaction hammer, it drives compaction hammer to rise at compaction hammer guide rod by motor, then freely fall, pound to the asphalt sample in sample mold.Move in circles according to this and realize repeatedly hitting real action.
But there is following shortcoming in the electronic real machine that hits of existing Marshall sample:
The lower end of compaction hammer is the asphalt sample directly acted in sample mold, and compaction hammer itself needs lifting to drive, and therefore, it is very large that the volume of compaction hammer can not do, thus have impact on vibrations and hit actual effect fruit.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provides a kind of reasonable in design, hits the real effective electronic compaction hammer mechanism hitting real machine of Marshall sample.
For achieving the above object, the technical solution of the utility model is the electronic compaction hammer mechanism hitting real machine of a kind of Marshall sample, include frame, the lead compaction hammer guide rod that is arranged in frame and straight skidding of longitudinally-moving leads the compaction hammer be arranged on compaction hammer guide rod, also include linkage block and the linkage block lifting drive mechanism for driving linkage block to be elevated, the movable block hole of lateral direction penetrating is provided with in the upper end of compaction hammer, movable block is laterally movably set in movable block hole, compaction hammer guide rod is simultaneously also through movable block, two ends of movable block pass hammer stem, linkage block on one end of movable block and chain is connected, and the interlock of the other end of movable block is arranged at the upper end of spring leaf, the lower end of spring leaf is fixed on the lateral wall of compaction hammer, spring leaf has to be made movable block move to linkage block direction and makes the two form the power be linked, compaction hammer guide rod is provided with wedge relative to the top of compaction hammer, this wedge has when compaction hammer moves to wedge position together with movable block and applies the power contrary with spring leaf acting force to movable block, and the bottom of described compaction hammer guide rod is fixedly installed second compaction hammer suitable with the test inner chamber of sample mold relative to compaction hammer.
Further setting is that the described movable block bottom surface relative to one end of spring leaf is provided with oblique film trap, the upper end of described spring leaf arranges the oblique bending sheet of one bending, this oblique bending sheet to be inserted in oblique film trap and with oblique film trap interference secure fit.By this setting, without the need to being carried out being fixedly connected with of spring leaf and movable block by screw, thus can effectively prevent the failure problems causing toner screw because of impact endurance test shock.
Principle of work and the advantage of this setting are: linkage block rises under the effect of linkage block lifting drive mechanism, it acts on movable block the inner, rise compaction hammer, when compaction hammer moves on to wedge position, wedge applies the power contrary with spring leaf to movable block, and the inner of movable block is retracted in compaction hammer, linkage block and movable block are separated, on the asphalt sample of the downward freely falling body impact of compaction hammer in the sample mold of below, this motion structure arranging compaction hammer arranges reliable and stable, in addition, this arranges the second compaction hammer, first can impact on this second compaction hammer at compaction hammer, and then the Asphalt Mixture Experiment acted in sample mold, so, the weight of the second compaction hammer can be utilized to expand overall impulsive force, improve and hit actual effect fruit
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
Accompanying drawing explanation
Fig. 1 the utility model is applied to the electronic schematic diagram hitting real machine of Marshall sample;
Fig. 2 the utility model embodiment structural representation.
