When the concrete sample on the lifting plate 21 moves upwards to be coated with the wax liquid, the concrete sample moves to the lower end of the sample mold 206, the lifting plate 21 continues to move upwards, the concrete sample can be extruded into the sample mold 206, automatic installation of the concrete sample is realized, a worker is not required to manually move the concrete sample onto the sample mold 206 in the whole process, the situation that the sealing effect between the concrete sample and the sample mold is poor due to the fact that the wax liquid on the side surface of the concrete sample is removed when the worker moves the concrete sample can be avoided;
the area of the disc 22 is the same as the cross-sectional area of the concrete test piece, and the concrete test piece can be positioned when being placed on the disc 22, so that the concrete test piece can smoothly enter the test piece mold.
The left end of the lifting plate 21 is provided with a second bar-shaped groove 31, a second bidirectional screw rod 32 is rotationally assembled in the second bar-shaped groove 31, the front side and the rear side of the second bidirectional screw rod 32 are both in threaded connection with a second sliding block 33, a second magnetic block 3 is arranged on the lower side of the second sliding block 33, and the front end of the second bidirectional screw rod 32 is connected with a second handle 34;
the upper end of the U-shaped frame 2 is provided with a pushing cylinder 207, and an output shaft of the pushing cylinder 207 is connected with a push plate;
After the concrete permeation resistance experiment is finished, the lifting plate 21 is moved to the upper end of the detection table 1, meanwhile, the second bidirectional screw rod 32 is driven to rotate through the second handle 34, the two second sliding blocks 33 are mutually far away, namely, the two second magnetic blocks 3 are driven to be mutually far away, a worker can push a concrete test piece and a test piece die onto the disc 22 again, then the first handle 204 is rotated to drive the two arc clamping plates 205 to relatively move so as to clamp the test piece die 206, the electric sliding rail is started to drive the lifting plate 21 to slide downwards, and in the process of the downward sliding of the lifting plate 21, the pushing cylinder 207 is started to drive the push plate to move downwards so as to push the concrete test piece downwards out of the test piece die 206, so that the concrete test piece is automatically taken out;
The concrete test piece continues to move downwards to the bottom at lifter plate 21, at this moment because two second magnetic path 3 keep away from each other, stagger each other with first magnetic path 244, consequently second magnetic path 3 will not adsorb with first magnetic path 244, and mounting panel 26 can not upwards overturn vertical state like this, so can not carry out waxing work to the concrete test piece, can conveniently take off the concrete test piece.
A through groove is formed in the middle of the upper end of the detection table 1, and a conveyor belt 101 is arranged in the through groove; after the concrete test piece is combined with the test piece mould 206, the lifting plate 21 is positioned at the upper end of the detection table 1 for treatment, and a worker can push the test piece mould 206 to the conveyor belt 101, namely, the test piece mould 206 can conveniently move left and right on the conveyor belt 101 and can conveniently move to the corresponding penetrometer 11, so that the labor is saved.
The above embodiments are merely illustrative of the principles of the present invention and its effectiveness, and are not intended to limit the invention. Modifications and variations may be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the invention. Accordingly, it is intended that all equivalent modifications and variations of the invention be covered by the claims of this invention, which are within the skill of those skilled in the art, can be made without departing from the spirit and scope of the invention disclosed herein.
