[0001] The utility model relates to the technical field of consistency measurement, in particular to a consistency measurement device for cement research and development. Background Technique
[0002] Consistency refers to the measure of the flowability of refractory mortar and refractory castable after adding water or liquid binder under the action of its own weight and external force. The smaller the consistency, that is, the greater the fluidity. A consistency tester refers to an instrument used for the consistency of concrete and asphalt, such as a penetrometer, a cement paste consistency meter, a mortar consistency meter, and an asphalt consistency tester.
[0003] At present, there are still some problems in the process of measuring the consistency of a cement paste consistency meter. That is, usually, personnel place the test mold on the upper surface of the bottom plate, then fill the cement into the test mold one by one, and finally place it under the test rod on the consistency meter for measurement. During this period, personnel cannot quickly and accurately place the test mold on the bottom plate and then place the bottom plate directly under the test rod, which affects the measurement value effect of the cement. Therefore, we propose a consistency measurement device for cement research and development to solve the above problems. Content of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0022] The technical solution provided by the present invention is as follows: As shown in Figure 1 , Figure 2 and Figure 3 , in this embodiment, a consistency measuring device for cement research and development includes a base 1. A support plate 2 is fixedly installed on the outside of the base 1. The other end of the support plate 2 is fixedly connected to a tester box 3. A test rod 4 is slidably connected in the tester box 3. A bolt part 5 for fastening the position of the test rod 4 is arranged on the tester box 3. A bottom plate 6 is arranged on the base 1. A leg plate 7 is fixedly arranged on the outside of the bottom plate 6. The leg plate 7 is inserted into the fitting groove 8. The fitting groove 8 is opened on the upper surface of the base 1. A test mold 9 is placed on the upper surface of the bottom plate 6. The upper surface of the bottom plate 6 and the bottom end of the test mold 9 are both provided with the same groove 10. Magnet sheets 11 are fixedly arranged in the grooves 10. The bottom plate 6 and the test mold 9 are both located directly below the test rod 4. Through the leg plate 7 arranged on the outside of the bottom plate 6, it can fit into the fitting groove 8, so that the bottom plate 6 can be directly located directly below the test rod 4. And after the test mold 9 is placed on the upper surface of the bottom plate 6, with the magnet sheets 11 closely attached to each other, the test mold 9 can be stably located on the upper surface of the bottom plate 6, effectively preventing the phenomenon of cement leakage and displacement of the test mold 9 during subsequent filling in the subsequent measurement. This structure is simple to operate and convenient for personnel to use. The leg plate 7 fits into the fitting groove 8. The upper edge of the fitting groove 8 is set to be inclined, so that the leg plate 7 can be smoothly inserted into the fitting groove 8. Anti-slip patterns 12 are opened on the outside of the test mold 9. The anti-slip patterns 12 are equidistantly distributed on the outside of the test mold 9. By arranging the anti-slip patterns 12, it can facilitate the subsequent pushing work of the test mold 9 from the surface of the bottom plate 6 by personnel. The bolt part 5 is meshed and connected to the tester box 3 through a fine-threaded thread, and one end of the bolt part 5 abuts against the outside of the test rod 4, which can stably fasten the position of the test rod 4.
[0023] As Figure 1 , Figure 4 and Figure 5As shown, a circular plate 13 is fixedly installed at the top end of the test rod 4. An arc-shaped plate 14 abuts against the lower surface of the circular plate 13. The arc-shaped plate 14 is sleeved on the outer side of the test rod 4. A support rod 15 is fixedly installed on the outer side of the arc-shaped plate 14. The other end of the support rod 15 is slidably connected to the tester box 3. A spring 16 is sleeved on the outer side of the support rod 15. One side of the arc-shaped plate 14 fits on the outer side of the test rod 4. The two ends of the spring 16 are respectively in close contact with the outer side of the tester box 3 and the support rod 15. By setting this structure, after the personnel place the bottom plate 6 loaded with cement and the test mold 9 below the test rod 4, they can push the outer side of the support rod 15 by hand, so that the arc-shaped plate 14 abuts against the outer side of the test rod 4. And as the bolt member 5 releases the restriction on the test rod 4, the test rod 4 can move downward, so that the circular plate 13 abuts against the top of the arc-shaped plate 14, and thus the bottom end of the test rod 4 can abut against the surface of the cement, facilitating the subsequent testing work on the cement. The arc-shaped plates 14 are symmetrically arranged on both sides of the test rod 4, which helps to position and stabilize the test rod 4.
[0024] The utility model provides a consistency measuring device for cement research and development. The specific working principle is as follows:
[0025] The device places the test mold 9 on the upper surface of the bottom plate 6, so that the magnet sheets 11 can be closely attached to each other, and then the test mold 9 can be stably located on the upper surface of the bottom plate 6. Then the personnel can fill the cement into the test mold 9 one by one. After that, the personnel place the bottom plate 6 on the upper surface of the base 1, so that the leg plate 7 can be inserted into the fitting groove 8, and then the test mold 9 is located directly below the test rod 4. Subsequently, the personnel push the outer side of the support rod 15 by hand, so that the arc-shaped plate 14 can fit on the outer side of the test rod 4. During this period, one end of the support rod 15 slides in the tester box 3 and the spring 16 is in a tightened state. Then the bolt member 5 is rotated in the positive direction, so that the test rod 4 slides down in the tester box 3, and then the circular plate 13 abuts against the top position of the arc-shaped plate 14, and the bottom end of the test rod 4 contacts the surface of the cement, thereby positioning the test rod 4.
[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
