The utility model has the advantages of the sample mold is fixed reliable and stable.
Description
Technical field
The utility model relates to that a kind of Marshall is electronic hits real machine, specifically refers to the electronic test mould fixed mechanism hitting real machine of Marshall.
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:
(1) sample mold of Marshall sample is all directly be placed on the worktable below compaction hammer, under the vibrations of compaction hammer repeat impact, and easy displacement.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provides the reliable Marshall of a kind of sample mold fixing-stable the electronic test mould fixed mechanism hitting real machine.
For achieving the above object, the technical solution of the utility model includes frame, frame is provided with worktable, this worktable is provided with sample mold, it is characterized in that: also include sample mold fixed mechanism, this sample mold fixed mechanism includes sample mold locating rack, and erect and to be arranged on worktable and to be positioned at the both sides sample mold backstay of sample mold, described sample mold locating rack includes the sample mold posting with the upper edge location fit of sample mold, and symmetry is fixedly installed on the guide plate of sample mold posting both sides, described guide plate coordinates with two sample mold backstay longitudinally guidings respectively, the top of sample mold backstay is provided with spring base, sheathed on sample mold backstay between this guide plate and spring base only have coil tension spring, the support tube that this sample mold backstay is arranged with relative to the rotated down of guide plate, the upper end of support tube supports with guide plate and coordinates, this support tube is provided with surface groove, and the sidewall of described sample mold backstay is provided with the lead guide finger that coordinate oblique with the surface groove of this support tube.
By this setting, sample mold is fixed on the below of sample mold posting, and rely on the acting force of coil tension spring, sample mold posting is made to keep elastic compression to sample mold in downward direction, and when sample mold takes out by needs, by rotational support cylinder, make support tube raise whole sample mold locating rack, and sample mold and sample mold posting are separated, convenient disassembly.
Further setting be described support tube outer wall on be fixedly installed turning handle.By this setting, facilitate the rotation of support tube.
Further setting is that the upper edge of described sample mold is provided with ring ladder groove, the inwall of the lower ora terminalis of described sample mold posting is provided with the annular convex ring of locating scarf with ring ladder groove.By this setting, improve the stability of locating between sample mold and sample mold posting.
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 structural representation hitting real machine of Marshall;
Fig. 2 the utility model sample mold fixed mechanism coordinates stereographic map with sample mold;
Fig. 3 is the STRUCTURE DECOMPOSITION figure of Fig. 2.
