The utility model will be described in detail below with reference to the drawings in connection with embodiments.

The cement mortar fluidity tester for engineering detection comprises a tester body 1, a dial 2, a truncated cone circular die 8 and a die sleeve 7, as shown in figures 1 to 3. Illustratively, the tester body 1 may be an existing jump table, the dial 2 may be mounted and fixed on a lifting column of the jump table, and the truncated cone circular die 8 and the die sleeve 7 may be conventional devices, which will not be described herein. The proper tester body 1 can be selected by a person skilled in the art according to actual needs so as to drive the dial 2 to lift and realize the measurement of the mobility of cement mortar, and the main innovation point of the utility model is that the design of the whole structure of the tester, especially the design of the dial 2 structure, does not relate to the improvement of the tester body 1, so that the description is omitted here.

The dial 2 is provided with positioning mechanisms for limiting the truncated cone circular die 8 and the die sleeve 7, the two groups of positioning mechanisms are uniformly arranged along the circumferential direction of the dial 2, and each positioning mechanism comprises a limiting piece 4 arranged at the edge of the dial 2 and a positioning piece 5 arranged on the limiting piece 4; the limiting piece 4 is detachably arranged on the dial 2, one end of the positioning piece 5 is detachably arranged on the limiting piece 4, and the other end of the positioning piece is provided with the accommodating groove 6; an opening is formed in one end, facing the truncated cone circular die 8, of the accommodating groove 6, positioning plates 14 are arranged at positions, corresponding to the openings, on the positioning piece 5, two positioning plates 14 are arranged at the left side and the right side, corresponding to the accommodating groove 6, of each positioning plate 14, and an accommodating gap communicated with the accommodating groove 6 is formed between the two positioning plates 14; a boss 15 is arranged on the positioning piece 5 at a position corresponding to the lower part of the positioning plate 14, and a fit clearance capable of being matched with the edge of the truncated cone circular die 8 exists between the boss 15 and the positioning plate 14.

Illustratively, the locating plate 14 and boss 15 are both fixed to the locating member 5. In actual use, as the truncated cone circular die 8 has the edge for placing the die sleeve 7, by arranging the positioning plate 14 and the boss 15 on the positioning piece 5, an operator can utilize the fit clearance between the positioning plate 14 and the boss 15 to realize the limit of the truncated cone circular die 8. Specifically, the positioning piece 5 can be connected with the edge of the truncated cone circular die 8 through the two positioning pieces 5, then the limiting piece 4 is arranged on the dial 2, and finally the positioning piece 5 is arranged on the limiting piece 4, so that the positioning and placement of the truncated cone circular die 8 can be realized. After the truncated cone circular die 8 is placed on the dial 2, the two positioning mechanisms can continuously and stably limit the truncated cone circular die 8, so that the truncated cone circular die 8 is prevented from moving when the die sleeve 7 is placed and cement mortar is filled subsequently, the operation difficulty of operators is reduced, and the experimental precision and the experimental efficiency are improved conveniently.

In the practical application process, the accommodating gap is communicated with the accommodating groove 6 through the opening, so that the accommodating groove 6 on the positioning piece 5 can be used for accommodating cement mortar which is surplus when the truncated cone circular mold 8 is troweled. Specifically, after the positioning mechanism is used for limiting the truncated cone circular mold 8, an operator can place the mold sleeve 7 on the truncated cone circular mold 8 and conveniently fill cement mortar into the truncated cone circular mold 8 by using the mold sleeve 7. After the cement mortar is better filled into the truncated cone circular mold 8 by using the stirring rod as much as possible, an operator can take the die sleeve 7 off the truncated cone circular mold 8, and a certain surplus cement mortar exists on the upper surface of the truncated cone circular mold 8. And then an operator can trowelle cement mortar on the top surface of the truncated cone circular die 8 by using a tool according to experimental requirements, and in the trowelling process, the operator can push surplus cement mortar into the accommodating groove 6 so as to realize the accommodation of the cement mortar and prevent the cement mortar from being scattered onto the dial 2.

Through accomodate the excessive cement mortar in holding tank 6, when the locating part 5 and the circular truncated cone mould 8 are taken off to the follow-up, the operating personnel can pull down locating part 5 and circular truncated cone mould 8 from locating part 4 together to take away the cement mortar in locating part 5 holding tank 6. Therefore, the residual cement mortar does not fall onto the dial 2, and an operator does not need to clean the dial 2 any more, so that the experiment can be directly performed, and the efficiency and the accuracy of the experiment can be further improved.

Optionally, the bottom surface of the accommodating groove 6 is an inclined surface, and one end of the inclined surface, which is inclined downward, is disposed towards the limiting member 4. By setting the bottom surface of the accommodating groove 6 to be an inclined surface, the volume of the accommodating groove 6 is increased, and more cement mortar can be accommodated in the accommodating groove 6. And the inclined plane is favorable to the flow of cement mortar, ensures that the cement mortar entering the accommodating groove 6 can be converged at one end of the accommodating groove 6, which faces the limiting piece 4. When in actual use, cement mortar which is converged at one end of the accommodating groove 6 towards the limiting part 4 along the inclined plane is not easy to flow back into the truncated cone circular mold 8 from the accommodating groove 6 when an operator dismounts the positioning part 5 and the truncated cone circular mold 8, so that the follow-up measurement experiment of the cement mortar at the truncated cone circular mold 8 is not influenced, and the smooth performance of the experiment is ensured.

In the practical application process, in order to be convenient for better accomodate surplus cement mortar on the truncated cone circular mould 8, the inclined upward one end of inclined plane can be with truncated cone circular mould 8 top surface parallel and level, perhaps slightly be less than truncated cone circular mould 8 top surface, and when the cement mortar was pushed into holding tank 6 to the operating personnel utilization instrument like this, the cement mortar was difficult for remaining on truncated cone circular mould 8 top surface.

In addition, two positioning plates 14 arranged corresponding to the left side and the right side of the accommodating groove 6 can also play a good role in guiding cement mortar. Alternatively, the positioning plate 14 may be an L-shaped structure, where the transverse end of the positioning plate 14 is disposed towards the truncated circular mold 8, and the longitudinal end is fixed on the positioning member 5. The transverse ends of the two positioning plates 14 can also adopt arc structures, so that the two positioning plates 14 can form a horn-shaped flow guiding structure, and the flow guiding structure can further facilitate operators to push cement mortar into the accommodating groove 6.

Alternatively, one end of the positioning plate 14 is arranged on the positioning piece 5, and the other end is provided with a fitting part which can be matched with the side wall of the die sleeve 7. Through setting up laminating portion on locating plate 14, utilize laminating portion and die sleeve 7 lateral wall laminating, also can realize spacing to die sleeve 7, ensure the stability of die sleeve 7 when filling cement mortar, avoid die sleeve 7 to take place to remove, be favorable to improving the filling efficiency of cement mortar. Meanwhile, the positioning plate 14 can also limit the upper end of the edge of the truncated cone circular die 8, so that the truncated cone circular die 8 is prevented from moving up and down, and the truncated cone circular die 8 is ensured not to move when cement mortar is filled.

Because the die sleeve 7 is of an inverted truncated cone structure, the diameter of the upper part is large, and the diameter of the lower part is small, the die sleeve 7 can play a good guiding role on the filled cement mortar under the limit of the positioning plate 14, so that the cement mortar can be ensured to flow into the truncated cone circular die 8 more smoothly, and the cement mortar is prevented from scattering out of the range of the truncated cone circular die 8. After the cement mortar is filled, an operator can conveniently and upwards take down the die sleeve 7, and the locating plate 14 can not block the die sleeve 7.

Alternatively, one end of the boss 15 is arranged on the positioning piece 5, and the other end is provided with an arc surface part which can be matched with the side wall of the truncated cone circular mould 8. The arc surface is favorable for better fitting of the boss 15 and the truncated cone circular die 8, so that the positioning piece 5 can play a better limiting role on the truncated cone circular die 8, and the truncated cone circular die 8 is prevented from moving. The two positioning pieces 5 can respectively clamp the two sides of the truncated cone circular die 8 under the limit of the limiting piece 4, so that the limit fixation of the truncated cone circular die 8 is realized. Meanwhile, the boss 15 can also support the lower end of the edge of the truncated cone circular die 8, so that an operator can synchronously drive the truncated cone circular die 8 to move upwards when moving the positioning piece 5 upwards, and separation of the truncated cone circular die 8 and the dial 2 is realized.
