The utility model discloses a technical scheme lie in: a thickness tester for a bituminous mixture compaction test piece comprises: the support body, the support body is shaft-like, is equipped with the stiff end with support body mutually perpendicular in support body one end, is equipped with the fixed bolster platform parallel with the stiff end on the stiff end, and the cover is equipped with the removal end frame on support body outer wall, the one end of removing the end frame is passed through the bolt fastening on the support body, is fixed with on the other end of removing the end frame and corrects the pad platform, correct pad platform and the coaxial and parallel relative setting of fixed bolster platform, be carved with the survey chi on the support body, and the same horizontal plane of mesa department of the initial point of survey chi and fixed bolster platform is fixed with the correction chi on the outer wall of correcting the pad platform.

Preferably, the fixing pad table and the correcting pad table are both circular, and the outer diameter of the correcting pad table is smaller than the inner diameter of the test mold opening.

Preferably, a guide groove is formed in the length direction of the support body, the tail end of the screw rod of the bolt is located in the guide groove, and the groove width of the guide groove is larger than the outer diameter of the screw rod of the bolt.

The utility model has the advantages that:

1. through the relative fixed pad platform that sets up from top to bottom and the correction pad platform, can carry out the centre gripping to the upper and lower face of test piece fast, can directly range estimation go out the actual height of test piece through surveying the chi, simultaneously can directly obtain the distance difference between test piece and the examination mould mouth through correcting the correction chi that fills up the bench, reduced the error problem that traditional measurement in-process human factor brought.

2. Through set up the guide way on the support body, make the removal end frame when up-and-down motion, the bolt is located the guide way all the time, plays the guide effect for the removal of removal end frame.

3. The utility model discloses simple structure, easy and simple to handle, practicality are strong, the measuring result directly obtains, need not the manual calculation.

Description of the drawings:

fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a left side view of FIG. 1;

FIG. 3 is a right side view of FIG. 1;

FIG. 4 is a diagram of the position relationship of the present invention when measuring a test piece;

wherein: the device comprises a support body 1, a guide groove 101, a measuring ruler 2, a fixing end 3, a movable end frame 4, a bolt 5, a fixing cushion table 6, a correcting cushion table 7, a correcting ruler 8, a test mould 9 and a test piece 10.

The specific implementation mode is as follows:

as shown in fig. 1 to fig. 3, the utility model relates to a bituminous mixture hits real test piece thickness measurement ware, include: the support body 1, support body 1 is shaft-like, and its cross section is the rectangle, and 1 one end of support body is equipped with stiff end 3 with 1 mutually perpendicular of support body, and stiff end 3 and support body 1 structure as an organic whole. Be equipped with the fixed bolster platform 6 parallel with stiff end 3 on stiff end 3, fixed bolster platform 6 is circular. The other end of support body 1 is for holding the end, and the cover is equipped with the removal end frame 4 that can reciprocate on the outer wall of support body 1, the one end of removing end frame 4 is passed through bolt 5 and is fixed on support body 1, is fixed with on the other end of removing end frame 4 and corrects and fill up platform 7, and removes end frame 4 cover and establish the same horizontal plane of lower terminal surface of support body 1 one end and the mesa department of correcting and filling up platform 7, just can accurately reflect the distance between fixed pad platform 6 and the correction pad platform 7 through the position that this lower terminal surface was located on survey chi 2. The correcting pad table 7 is circular, the outer diameter of the correcting pad table 7 needs to be smaller than the inner diameter of an opening of the test mold 9, so that the correcting pad table 7 can stretch into the test mold 9 to be attached to the test specimen 10, the correcting pad table 7 and the fixing pad table 6 are coaxial and parallel and arranged oppositely, the measuring scale 2 is carved or adhered on the support body 1, the starting point of the measuring scale 2 and the table top of the fixing pad table 6 are located on the same horizontal plane, and measuring accuracy can be guaranteed through the design. A correction ruler 8 is fixed on the correction pad platform 7, and the starting point of the correction ruler 8 is on the same horizontal plane with the table top of the correction pad platform 7.

Further, in order to make the up-and-down movement process of the movable end frame 4 more accurate, a guide groove 101 is formed in the length direction of the support body 1, the horizontal position of the bottom of the guide groove 101 is higher than the position of the starting point of the measuring ruler 2, and the horizontal position of the top of the guide groove 101 is higher than the maximum scale value of the measuring ruler 2. The tail end of the screw rod of the bolt 5 penetrates through the side wall of the movable end frame 4 and then extends into the guide groove 101, the groove width of the guide groove 101 is larger than the outer diameter of the screw rod of the bolt 5, and when the movable end frame 4 needs to be fixed, the bottom end of the screw rod of the bolt 5 is tightly pressed on the inner wall of the guide groove 101; when the movable end frame 4 needs to be moved, the screw of the bolt 5 is positioned in the guide groove 101, and the bolt 5 can move up and down freely.

The working process is as follows:

as shown in FIG. 4, after the asphalt mixture is compacted, the test mold 9 is taken out, firstly, the fixing end 3 of the utility model is horizontally placed on the workbench, the table surface of the fixing pad table 6 is tightly attached to the lower opening end of the test mold 9 (at this time, the lower opening end of the test mold 9 is flush with the lower surface of the test specimen 10), secondly, the movable end frame 4 is moved downwards, the table surface of the correcting pad table 7 on the movable end frame 4 is tightly attached to the upper surface of the test specimen 10 in the upper opening end of the test mold 9, then the bolt 5 is screwed to fix the movable end frame 4 on the bracket body 1, at this time, the scale value of the intersection of the movable end frame 4 and the measuring ruler 2 is the actual height of the test specimen 10 after compaction, meanwhile, the scale value of the correcting ruler 8 at the upper opening of the test mold 9 is the height of the test specimen 10 from the upper opening of the test mold 9, and finally, according to the height standard 63.5mm + -1.3 mm (standard specimen) or 95.3 + -2.5 mm (, the calculated height of the test piece 10 is obtained through calculation and compared with the measured height of the test piece 10, so that the deviation between the calculated height of the test piece 10 and the actual thickness of the test piece 10 is corrected, and whether the test piece 10 meets the height standard or not is determined, and if the test piece 10 does not meet the height standard, the test piece 10 is discarded.
