Description

Technical Field

[0001] The utility model relates to the technical field of grouting material production, in particular to a device for testing the fluidity of grouting materials. Background Technique

[0002] Cement-based grouting materials are commonly used in construction. They have characteristics such as large fluidity and self-leveling. Moreover, the strength and porosity of the hardened slurry are affected by the fluidity. Therefore, selecting cement-based grouting materials with good fluidity is one of the main measures to ensure project quality.

[0003] During the production process of grouting materials, it is necessary to test their fluidity. In the prior art, the fluidity test of grouting materials is usually reflected by the viscosity value test. There are many types of viscosity value test equipment for fluid materials at home and abroad, such as viscometers, rotational viscometers, and Blaine viscometers. These devices are used to test the viscosity value of slurries. However, through the viscosity value test equipment, the fluidity of grouting materials cannot be directly observed, which is not convenient for the comparative test of the fluidity of grouting materials with the same properties at different inclination angles, nor for the comparative test of the fluidity of grouting materials with different properties at the same angle. In view of this, we propose a device for testing the fluidity of grouting materials. Content of the Utility Model

The two gears 711 mesh with each other. A spiral chute is provided on the circumferential outer wall of the cylindrical cam 74, and a sliding column 77 slidably connected to the chute on the outer wall of the cylindrical cam 74 is fixed on the front side surface of the moving block 75.

[0040] Finally, it should be noted that components such as the deflection motor 712 and the solenoid valve 12 involved in the present utility model are all common standard components or components known to those skilled in the art.

Their detailed connection means are all well-known technologies in the art.

[0041] In the specific use process of this embodiment, when it is necessary to conduct a comparative test on the fluidity of different grouting materials, first, start the deflection motor 712 through an external PLC. The output shaft of the deflection motor 712 rotates to drive the coaxial connected rotating shaft 713 to rotate. The rotation of the rotating shaft 713 drives the coaxial connected same-side gear 711 on the same side to rotate. The rotation of this gear 711 drives the rotation of another meshing gear 711. The rotation of another gear 711 drives the coaxial fixed connecting column 73 to rotate. The rotation of the connecting column 73 drives the coaxial fixed rotating rod 72 to rotate. The rotation of the rotating rod 72 drives the coaxial fixed cylindrical cam 74 to rotate. The rotation of the cylindrical cam 74 drives the sliding of the chute on its outer wall. During the rotation of the chute on the outer wall of the cylindrical cam 74, it drives the sliding column 77 connected to it to move. The sliding column 77 moves under the guiding action of the moving block 75, the guiding block 76, and the guiding groove on the right surface of the vertical plate end of the vertical plate 71. The movement of the moving block 75 drives the fixed connecting rod 78 to move. The movement of the connecting rod 78 drives the fixed lifting rod 79 to move. The movement of the lifting rod 79 drives the articulated limit block 710 to slide inside the limit groove on the bottom surface of the mounting plate 4. During the sliding of the limit block 710 in the limit groove on the bottom surface of the mounting plate 4, it also drives the mounting plate 4 to deflect. The deflection of the mounting plate 4 drives several transparent tubes 8 to deflect. When several transparent tubes 8 deflect to the appropriate angular position, turn off the deflection motor 712 through an external PLC, and thus complete the adjustment work;

[0042] Immediately open several manual valves 11, and then add different grouting materials with different properties into several transparent tubes 8 through several feeding funnels 9 respectively. Use an external timer to control the flow time of different grouting materials. According to the scale lines on the outer walls of several transparent tubes 8, the positions reached by different grouting materials at the same time can be clearly observed, and thus the fluidity of different grouting materials can be compared and tested. According to the above description, it is also possible to realize the comparative test of the fluidity of grouting materials with the same properties at different inclination angles.
