Description

Technical Field

[0001] The utility model relates to a fluidity testing device for gypsum-based self-leveling mortar, which is used for testing the fluidity of the gypsum-based self-leveling mortar. Background Art

[0002] Gypsum-based self-leveling mortar is a material specially used for indoor floor leveling, which is made by carefully configuring and evenly mixing high-strength gypsum, aggregates and various building chemical additives in the factory. Gypsum-based self-leveling mortar can achieve automatic leveling during the construction process, without the need for manual secondary leveling. It is easy to construct and has high flatness. The fluidity of gypsum-based self-leveling mortar is directly related to the construction quality. During the construction process, it is necessary to sample the mixed gypsum-based self-leveling mortar and conduct a fluidity test on the obtained samples to obtain the appropriate ratio of water and powder, that is, the optimal water-powder ratio, and obtain gypsum-based self-leveling mortar with fluidity that meets the requirements.

[0003] The Chinese patent specification with application number: 202311234352.9 discloses a gypsum-based self-leveling mortar mixing device with a fluidity testing device, a fluidity test mold is placed on the operating table of the device, and a vertical movable guide structure is arranged between the fluidity test mold and the operating table. This vertical movable guide structure is three friction wheels 22 arranged on the periphery of the fluidity test mold 21, each friction wheel 22 is respectively rollingly matched with the outer peripheral surface of the fluidity test mold 21, and each friction wheel is assembled by rotation through a support frame, and the support frame 23 is two arc frames, and the two arc frames are respectively arranged at the two ends of the corresponding friction wheel 22, and the friction wheel 22 is assembled on the support frame 23 by rotation at both ends, and the lower end of the support frame 23 is fixed on the operating table 4, and the fixed point of the support frame 23 and the operating table 4 is outside the test circle scale line. It can accurately position the fluidity test mold, so that the test is accurate, but in the process of testing the fluidity test mold, multiple tests are usually required to obtain the best water-powder ratio. When the gypsum-based self-leveling mortar mixing equipment with a fluidity testing device is used for fluidity testing, the slurry left on the operating table needs to be cleaned after a fluidity test mold test. However, the support frame fixed on the operating table will hinder the cleaning process, making it inconvenient to clean the operating table. In addition, after the operating table is cleaned, a lot of water will remain on it. If it is not cleaned, it will also affect the next experimental results. These all require the operator to clean manually, which is not only labor-intensive, but also difficult for one person to operate. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings herein can be arranged and designed in various different configurations.

[0044] The embodiment of the fluidity testing device for gypsum-based self-leveling mortar involved in the utility model is as follows: Figure 1-Figure 15In the figure, the workbench 15 is a platform, and a rodless cylinder 16 is fixedly arranged at one end of the workbench 15. The rodless cylinder is a commercially available part and extends to the outside of both sides of the workbench 15. A wiper 18 is fixedly arranged on the moving part 17 of the rodless cylinder 16. One end of the wiper 18 is fixed on the moving part 17, and the other end is freely suspended and extends to the outside of the other end of the workbench. The wiper 18 scrapes and cooperates with the upper surface of the workbench when moving, and the wiper 18 can move from the outside of one side of the workbench 15 to the outside of the other side of the workbench 15. A linear drive structure is also fixedly arranged on the workbench 15, and the linear drive structure here is a hydraulic cylinder 19, which is indirectly fixed to the workbench 15. A feed pipe 20 is fixedly arranged on the piston rod of the hydraulic cylinder 19. After the fluidity test mold 8 contacts the workbench 15, the outlet of the feed pipe 20 can move to the upper port of the fluidity test mold 8, and the other end of the feed pipe 20 is connected to a sampling device for extracting gypsum-based self-leveling mortar slurry when in use.

[0045] A fixed mounting plate 1 is arranged above the workbench 15, and the fixed mounting plate is fixed to the workbench 15 through a column 21, the lower end of the column 21 is fixed on the workbench 15, one side of the fixed mounting plate 1 is fixed to the upper ends of the two columns 21, the hydraulic cylinder 19 is also fixed on the column, a plate body 22 is fixed on the column, one end of the plate body 22 is fixed on the column, and the other end extends to the fluidity test mold 8, and the hydraulic cylinder 19 is fixed on the upper surface of the plate body 22. A cylinder structure is provided on the fixed mounting plate 1. The cylinder structure comprises a cylinder body 2 and a piston assembly which cooperate with each other. The piston assembly comprises a piston body 3 and a piston rod 4 which cooperate with the cylinder body 2 in a sealed and sliding manner. The piston rod 4 comprises an upper rod 5 and a lower rod 6 which extend out from the two ends of the cylinder body 2 in a sealed manner. That is to say, the piston body 3 is in the middle of the piston rod 4 and the piston body 3 does not extend out of the cylinder body 2. The upper rod 5 is fixedly mounted on the fixed mounting plate 1. The lower part of the cylinder body 2 is provided with a fixing claw 7 which is arranged on the outer periphery of the lower rod 6. The fixing claw 7 is used to lift the fluidity test mold 8 as the cylinder body 2 moves upward. That is to say, when the cylinder body 2 slides upward, the fixing claw 7 lifts the fluidity test mold 8 and slides upward with the cylinder body 2; the piston rod 4 has a through hole 9 penetrating the upper and lower rod parts, and a cleaning piece 10 is arranged in the through hole 9. The upper end of the cleaning piece 10 is fixed on the fixed mounting plate 1, and the lower end of the cleaning piece 10 is provided with a scraping ring 11. The outer peripheral surface of the scraping ring 11 is used to scrape and cooperate with the inner wall of the fluidity test mold 8 during the upward movement of the cylinder body 2. That is to say, the positions of the cleaning piece 10 and the scraping ring 11 arranged at the lower end are fixed. After the fluidity test mold 8 is lifted to a certain extent, the scraping ring 11 extends into the fluidity test mold 8 and scrapes the inner wall of the fluidity test mold 8.

[0046] Specifically, the center line of the cylindrical surface where the fixed claw 7 is located coincides with the center line of the fluidity test mold 8. The center line of the cylindrical surface where the fixed claw 7 is located corresponds to the center point of the test circle scale line on the matching workbench, so that the inner hole axis of the fluidity test mold 8 passes through the center point of the test circle scale line, thereby realizing the positioning of the fluidity test mold.

[0047] Specifically, the fixed claw 7 is tightly matched with the fluidity test mold 8 through the inner teeth 12 at its free end. The inner teeth 12 are clamped on the outer peripheral surface of the fluidity test mold 8, and the fluidity test mold 8 can be fixed on the fixed claw 7, so that the fluidity test mold 8 moves up and down with the fixed claw 7.

[0048] Specifically, the inner surface of the inner tooth 12 is an arc surface on a cylinder, and the inner surface of the inner tooth 12 matches the outer peripheral surface of the flow test mold 8 .

[0049] Specifically, the upper end surface of the inner teeth 12 is used to cooperate with the retaining spring 13 provided on the outer circumference of the fluidity test die 8 to prevent downward movement. In other words, the retaining spring 13 is provided on the outer circumference of the fluidity test die 8, and the upper end surface of the inner teeth 12 is located below the retaining spring 13. The retaining spring 13 can prevent the fluidity test die 8 from sliding downward relative to the fixed claw 7, thereby ensuring that the fluidity test die 8 and the fixed claw 7 slide up and down synchronously.

[0050] Specifically, the fixed claw 7 is arranged on the cylinder body 2 through a cylinder body 14, one end of the cylinder body 14 is connected to the cylinder body 2, and the fixed claw 7 is arranged on the end surface of the other end of the cylinder body 14. The cylinder body 14 extends the initial distance between the fixed claw 7 and the scraper ring 11, so that the fluidity test mold 8 cannot contact the scraper ring 11 when it is lifted by the fixed claw 7 for fluidity test, so as to avoid affecting the fluidity test result; after a fluidity test is completed, the fixed claw 7 continues to lift the fluidity test mold 8 upward, so that the scraper ring 11 passes through the fluidity test mold 8 and scrapes the inner wall of the fluidity test mold 8 to clean the slurry remaining in the fluidity test mold 8.

[0051] Specifically, the diameter of the through hole 9 is larger than the outer diameter of the fluidity test die 8. When the fixed claw 7 lifts the fluidity test die 8 upward, the piston rod 4 can accommodate the fluidity test die 8 to slide in the through hole 9 thereof.

[0052] Specifically, the cleaning member 10 is in the shape of a stepped shaft as a whole, and the scraper ring 11 is a large diameter section.

[0053] When in use, first connect the equipment, move the fluidity test mold 8 downward to contact the workbench, extend the piston rod of the hydraulic cylinder to drive the feed pipe to the top of the fluidity test mold 8, output the material through the sampling device, inject the stirred gypsum-based self-leveling mortar slurry into the fluidity test mold 8, and then slide the cylinder body 2 upward to lift the fluidity test mold 8 to leave the workbench, and the slurry in the fluidity test mold 8 will flow from the lower end of the fluidity test mold 8 to the workbench to perform the first fluidity test; during the upward movement of the fluidity test mold 8, the scraper ring 11 can scrape the inner wall of the fluidity test mold 8, so that the fluidity test mold 8 can be scraped clean; because the fluidity test mold 8 has left the workbench, there is space for scraping the workbench, and water can be flushed to the workbench at this time, and the wiper plate can be driven to move to remove the slurry on the workbench. In this way, the fluidity test mold 8 and the workbench are cleaned, and it does not affect the fluidity test again. Slide the cylinder body 2 downward to place the fluidity test mold 8 on the workbench, and the fluidity test can be performed again.

[0054] The air cylinder structure in the above embodiment can be replaced by an oil cylinder structure.

[0055] In the above embodiment, the center line of the fixed claw coincides with the center line of the fluidity test mold. In other embodiments, their center lines may not coincide, but the inner hole axis of the fluidity test mold needs to pass through the center point of the test circle scale line.

[0056] In the above embodiment, the fixed claw is tightly matched with the fluidity test mold through the inner teeth at its free end. In other embodiments, the inner teeth may not be provided, but the fixed claw is directly tightly matched with the fluidity test mold to lift the fluidity test mold.

[0057] In the above embodiment, the inner retracted tooth cooperates with the outer peripheral surface of the fluidity test mold through the arc surface of its inner surface. In other embodiments, the inner retracted tooth can also cooperate with the fluidity test mold in other ways, such as the two cooperate with a protrusion protruding on the inner retracted tooth and a groove provided on the outer peripheral surface of the fluidity test mold.

[0058] In the above embodiment, a retaining spring is provided on the outer peripheral surface of the fluidity test mold. In other embodiments, the retaining spring may not be provided, but the inner teeth and the outer wall of the fluidity test mold may be riveted together with rivets to prevent the fluidity test mold from moving downward relative to the inner teeth.

[0059] In the above embodiment, a cylinder is provided between the fixed claw and the cylinder body. In other embodiments, the cylinder may not be provided, but the length of the fixed claw may be increased so that the fluidity test mold does not contact the scraper ring when it is lifted by the fixed claw for fluidity testing.

[0060] In the above embodiment, the diameter of the through hole is larger than the outer diameter of the fluidity test mold. In other embodiments, the diameter of the through hole may not be larger than the outer diameter of the fluidity test mold. In this case, it is necessary to ensure that when the fluidity test mold moves up to the limit distance for the scraper ring to clean its inner wall, the upper end surface of the fluidity test mold is still below the lower end surface of the piston rod.

[0061] In the above-mentioned embodiment, the cleaning member is in the shape of a stepped shaft. In other embodiments, the cleaning member may also be in the shape of a cylinder, with the scraping ring being located at the lower end thereof.

[0062] In the above embodiment, the fixed claw lifts the fluidity test mold by tightly fitting with the fluidity test mold. In other embodiments, the fixed claw and the fluidity test mold may also be fitted with each other in other ways, such as threaded fitting.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate but not to limit the technical solutions of the present invention, and any equivalent substitutions of the present invention and any modifications or partial substitutions that do not depart from the spirit and scope of the present invention shall be included in the scope of protection of the claims of the present invention.
