With reference to fig. 1, fig. 2 and fig. 3, an embodiment of the present invention provides a low-temperature asphalt segregation degree detection apparatus, including: an inner mould ring 1, an outer mould sleeve 2 and a chassis 3, wherein,

the inner mould ring 1 can be provided with a plurality of inner mould rings, the utility model discloses inner mould ring 1 is equipped with four as an example, each inner mould ring 1 internal diameter is equal, and four inner mould rings 1 are coaxial cooling ring 101, first inner mould ring 102, second inner mould ring 103 and third inner mould ring 104 from top to bottom in proper order, each inner mould ring 1 and chassis 3 can be dismantled and connected, so that each inner mould ring 1 inside constitutes a smooth cylindrical inner cavity (in practice, thin layer glycerin and talcum powder isolating liquid can be usually smeared on the inner wall of the containing cavity for convenient demoulding), wherein, the end surfaces of contact between each adjacent inner mould ring 1 and between third inner mould ring 104 and chassis 3 are mutually attached and sealed;

the outer mold sleeve 2 is sleeved outside the side wall of each inner mold ring 1, the top end of the outer mold sleeve 2 can be tightly pressed on the top end face of the cooling ring 101, and the other end of the outer mold sleeve 2 is detachably connected to the chassis 3.

Adopt above-mentioned scheme:

because the contact surfaces between the adjacent inner mold rings 1 and between the third inner mold ring 104 and the chassis 3 are both attached, an inner cavity with an open top end is formed inside the inner mold rings, and the inner mold rings 1 and the chassis 3 are vertically extruded together through the outer mold sleeve 2 to enhance the sealing performance of the device, at the moment, the inner cavity can be used as a containing cavity for containing heated asphalt; after the asphalt is cooled, firstly taking out the outer mold sleeve 2, and then sequentially taking out the inner mold rings 1 from top to bottom, thus finally completing mold taking of the cooled asphalt; in conclusion, the device does not need to break the test mold to take out the asphalt, but sequentially disassemble the containing cavity containing the asphalt, so that the test mold can be repeatedly used.

Further, between each adjacent inner mould ring 1 to and all be equipped with the location down along 4 on the one side that contacts between third inner mould ring 104 and the chassis 3, the location is along 4 being cyclic annular and its and inner mould ring 1 is coaxial down, each adjacent inner mould ring 1, perhaps third inner mould ring 104 with chassis 3 all along 4 looks joints through the location down, through this location down along 4's setting, when reinforcing each adjacent inner mould ring 1 and with chassis 3 between stability, also improved the holistic sealing performance of device.

Further, the positioning lower edge 4 can be a step surface; certainly, should fix a position down along 4 still can annular constant head tank, corresponding, the constant head tank can further improve the sealing performance of device for the stair surface, nevertheless also can make the staff difficult with each interior mould ring 1 and chassis 3 separately simultaneously, so can choose according to actual need in the use.

Further, the bottom end of the outer mold sleeve 2 is screwed to the bottom plate 3, and by rotating the outer mold sleeve 2, the top end of the outer mold sleeve 2 is gradually pressed against the top end face of the cooling ring 101, and finally the four inner mold rings 1 in the outer mold sleeve 2 are pressed against each other.

The utility model provides another kind of embodiment, the laminating of the internal face of external mold sleeve 2 and the outer wall of each interior mould ring 1 to further strengthen the holistic sealing of device.

The utility model provides another embodiment, in order to conveniently install and dismantle the outer mold sleeve 2, the outer side surface of the outer mold sleeve 2 is provided with an anti-skid groove; meanwhile, the edge of the chassis 3 extends out of the outer wall surface of the sleeve, the bottom end of the outer mold sleeve 2 is in threaded connection with the inside of the chassis 3, and the ring side of the chassis 3 can be used as an acting force area for dismounting the outer mold sleeve 2.

The utility model provides another embodiment, because still need segment pitch after the drawing of patterns, the drawing of patterns mode of this device is the sectional type drawing of patterns in addition, then, in order to alleviate staff's operating procedure, first inner mould ring 102, second inner mould ring 103 and third inner mould ring 104 size are identical completely; when the mould is disassembled, after the first inner mould ring 102 is taken out, the asphalt above the surface can be cut off along the top end surface of the second inner mould ring 103 to be used as a first section in the conventional asphalt shearing process; similarly, when the second inner mold ring 103 and the third inner mold ring 104 are sequentially removed, the remaining asphalt may be cut off along the top end surface of the third inner mold ring 104 and the top end surface of the base plate 3, and used as the second section and the third section in the conventional asphalt shearing process; considering that the volume of asphalt is likely to decrease after the asphalt is cooled, in order to ensure that the volumes of three sections of asphalt are completely consistent, the inner mold ring 1 further comprises a cooling ring 101 arranged at the top of the first inner mold ring 102, when heated asphalt is poured, the asphalt can be submerged into the cooling ring 101, and a part of the asphalt is still located inside the cooling ring 101 after the asphalt is cooled, in the demolding process, the cooling ring 101 is firstly taken down, and then the asphalt originally located inside the cooling ring 101 is cut off along the top end of the first inner mold ring 102, so that uncertain factors which may influence the volume of the asphalt due to temperature changes are eliminated.

The utility model discloses a working process does: because the contact surfaces between the adjacent inner mold rings 1 and between the third inner mold ring 104 and the chassis 3 are both attached to each other, an inner cavity with an opening at the top end is formed inside the inner mold rings, then the adjacent inner mold rings 1 and the chassis 3 are primarily sealed through the positioning lower edges 4, and then the inner mold rings 1 and the chassis 3 are vertically extruded together through rotating the outer mold sleeve 2 to complete secondary sealing; after the asphalt is cooled, firstly, the outer mold sleeve 2 is rotated reversely and taken out, and in the process, the outer mold sleeve 2 is not in direct contact with the asphalt, so that the outer mold sleeve 2 can be taken out easily; then, sequentially taking out the cooling ring 101, the first inner mold ring 102, the second inner mold ring 103 and the third inner mold ring 104 from top to bottom, simultaneously, taking out one inner mold ring 1, sequentially shearing asphalt into four sections along the end surface of the inner mold ring 1 or the chassis 3 adjacent to the inner mold ring 1, and taking the second section and the fourth section as samples for the next test; to sum up, because this device need not to destroy the examination mould and takes out pitch, but will hold the appearance chamber of pitch and disassemble in proper order for this examination mould repeatedly usable.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
