Description

Technical Field

[0001] This utility model relates to the field of cement mortar flowability measurement technology, and in particular to a cement mortar flowability measurement device. Background Technology

[0002] The cement mortar flowability tester, also known as the cement mortar flowability tester, is a special testing instrument used to determine the flowability of cement mortar. It is also one of the most important pieces of equipment in the testing of the physical properties of cement. Its use is designed and operated in accordance with the national standard GB / T 2419-2005 "Method for Determination of Cement Mortar Flowability".

[0003] In existing technologies, such as the cement mortar flowability tester disclosed in CN 221326254 U, the test shell, the tester platform, the first magnetic ring, the second magnetic ring, the connecting ring, the test mold, the aggregate trough, the curved support, the bolts, the cylinder, the telescopic rod and the scraper are arranged in a coordinated manner. When using this device, the operator can simply place the test shell on the top of the tester platform, align the connecting ring with the first magnetic ring, and allow the first and second magnetic rings to attract each other, thereby fixing the connecting ring on the test shell and limiting the position of the test mold. The operation is simple and quick, and it can be removed by simply lifting it upwards.

[0004] However, it also has some shortcomings. For example, although the test mold can be fixed on the test shell by the cooperation of the first magnetic ring, the second magnetic ring and the connecting ring, and it can be removed by simply lifting it upwards, if the operator shakes the test mold during the process of lifting it upwards, the cement mortar will deform, which will cause testing errors. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a cement mortar flowability measuring device that can improve the accuracy of cement mortar test values.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a cement mortar flowability measuring device, including a base, a support component is provided at the center of the base, and a bouncing table is provided on the top of the support component; a telescopic device, two of which are respectively installed on the left and right sides of the base of the support component; a mounting plate, the left and right ends of which are respectively connected to the telescopic ends of the telescopic device, the mounting plate is located above the bouncing table, and a mounting groove penetrating the mounting plate is opened at the center of the mounting plate, the mounting groove being directly above the center of the bouncing table; and a trial mold assembly, which is installed in the mounting groove and is detachably connected to the mounting plate through the mounting groove.

[0007] A further preferred embodiment of this utility model is as follows: the trial mold assembly includes a truncated cone mold, which is installed in an installation groove, and a first connecting ring with a size larger than that of the installation groove is provided on the top of the truncated cone mold; a limiting protrusion ring, which is installed on the upper surface of the first connecting ring; and a mold sleeve, with a second connecting ring provided at the bottom of the mold sleeve, and a limiting groove for accommodating the limiting ring is provided at the bottom of the second connecting ring, and the mold sleeve is connected to the truncated cone mold through the second connecting ring.

[0008] A further preferred embodiment of this utility model is as follows: the support assembly includes a support base, which is hollow, and a bearing platform is provided on the top of the support base, with the bouncing tabletop located on the bearing platform; a push rod, which is installed in the support base, with its top extending through the bearing platform and connecting to the bouncing tabletop, and the push rod slidably connected to the bearing platform; a push plate, which is installed at the bottom of the push rod and slidably connected to the interior of the support base, with multiple first guide blocks provided on the side wall of the push plate, and multiple first guide grooves slidably connected to the first guide blocks provided on the inner wall of the support base; and a drive motor, which is installed on the side wall of the support base, with its output end located in the support base, and a cam provided on the output end of the drive motor.

[0009] A further preferred embodiment of this utility model is that both the support component and the telescopic device are detachably connected to the base by bolts.

[0010] A further preferred embodiment of this utility model is as follows: a plurality of second guide blocks are evenly arranged on the outer wall of the push rod, and a second guide groove is provided at the sliding connection between the support platform and the push rod to slide and connect with the second guide blocks.

[0011] A further preferred embodiment of this utility model is that an impact ring is provided on the top of the support platform.

[0012] Compared with the prior art, the advantages of this utility model are that it can avoid the problem of the test mold assembly shifting on the bouncing table, thus ensuring the filling effect of cement mortar in the test mold assembly. Furthermore, because the mounting groove is located directly above the center of the bouncing table, when the telescopic device moves the test mold assembly to the bouncing table via the control mounting plate, it will be centered on the bouncing table. This ensures a high degree of consistency and symmetry in the impact energy, vibration mode, and slurry diffusion environment used in the cement mortar testing, thereby allowing the measured flowability value to truly reflect the water... The working properties of cement mortar (flowability and water demand) require demolding of the mold assembly from the filled cement mortar. The telescopic device is activated again to extend its telescopic end. As the telescopic end extends, it can move the mold assembly away from the bouncing table via the mounting plate until the cement mortar in the mold assembly detaches. This prevents deformation of the cement mortar under test due to shaking of the mold assembly during demolding. Thus, the accuracy of cement mortar test values ​​is improved through the design of the telescopic device, mounting plate, and mounting groove. Attached Figure Description

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0017] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0018] This embodiment mainly describes the structure of the cement mortar flowability measuring device, as follows: like Figures 1-8 As shown, the cement mortar flowability measuring device includes a base 1, a support component 2, and two telescopic devices 3. The support component 2 is installed at the center of the base 1, and the two telescopic devices 3 are respectively installed on the left and right sides of the base 1 of the support component 2. A bouncing tabletop 6 is provided on the top of the support component 2, and the support component 2 can control the bouncing tabletop 6 to bounce on the support component 2. A mounting plate 4 is provided at the telescopic end of the two telescopic devices 3, and the mounting plate 4 is located above the bouncing tabletop 6. A mounting groove 41 is provided through the center of the mounting plate 4, and the mounting groove 41 is located directly above the center of the bouncing tabletop 6. A test mold component 5 is provided in the mounting groove 41, and the test mold component 5 is detachably connected to the mounting plate 4 through the mounting groove 41. When it is necessary to fill the mold assembly 5 with cement mortar, the telescopic device 3 is activated and its telescopic end is shortened until the mold assembly 5 is positioned on the bouncing table 6. Because the mold assembly 5 is located in the mounting groove 41 on the mounting plate 4, the filling of the mold assembly 5 with cement mortar can prevent the mold assembly 5 from shifting on the bouncing table 6, thus ensuring the filling effect of the cement mortar in the mold assembly 5. At the same time, because the mounting groove 41 is located directly above the center of the bouncing table 6, when the telescopic device 3 moves the mold assembly 5 to the bouncing table 6 by controlling the mounting plate 4, it can be positioned at the center of the bouncing table 6. In this way, the impact energy and vibration of the cement mortar are guaranteed during testing. The high consistency and symmetry of the dynamic mode and slurry diffusion environment ensure that the measured flowability value can truly reflect the working performance (flowability and water demand) of cement mortar. When it is necessary to demold the test mold assembly 5 from the filled cement mortar, the telescopic device 3 is activated again to extend the telescopic end of the telescopic device 3. As the telescopic end of the telescopic device 3 extends, it can drive the test mold assembly 5 away from the bouncing table 6 through the mounting plate 4, until the cement mortar filled in the test mold assembly 5 is detached from the test mold assembly 5. In this way, when demolding the cement mortar, the cement mortar to be tested will not be deformed due to the shaking of the test mold assembly 5. Thus, the accuracy of the cement mortar test value is improved by setting the telescopic device 3, the mounting plate 4, and the mounting groove 41.

[0019] Furthermore, to facilitate the disassembly and assembly of the cement mortar flowability measuring device, both the support assembly 2 and the telescopic device 3 are detachably connected to the base 1 by bolts.

[0020] The trial mold assembly 5 includes a truncated cone mold 51 installed in the mounting groove 41 and a mold sleeve 52 installed on the truncated cone mold 51. A first connecting ring 511 with a size larger than that of the mounting groove 41 is provided on the top of the truncated cone mold 51. A limiting protrusion ring 512 is provided on the upper surface of the first connecting ring 511. A second connecting ring 521 is provided at the bottom of the mold sleeve 52. A limiting groove 522 for accommodating the limiting ring is provided at the bottom of the second connecting ring 521. The mold sleeve 52 is connected to the truncated cone mold 51 through the second connecting ring 521. When using the test mold assembly 5, firstly, the mold sleeve 52 is installed on top of the truncated cone mold 51. Then, the operator fills the truncated cone mold 51 with the cement mortar to be tested through the mold sleeve 52. After the truncated cone mold 51 is filled, the mold sleeve 52 is removed from the truncated cone mold 51. At the same time, the operator scrapes down any cement mortar protruding from the top of the truncated cone mold 51. To prevent the truncated cone mold 51 from detaching from the mounting groove 41 when it is in the mounting groove 41, a first connecting ring 511 with a size larger than the mounting groove 41 is provided on the top of the truncated cone mold 51. This ensures that the truncated cone mold 51 is properly connected to the mounting groove 41. To ensure the reliability of the conical mold 51 in the mounting groove 41, and to facilitate the connection between the mold sleeve 52 and the truncated conical mold 51, a second connecting ring 521 is provided at the bottom of the mold sleeve 52. To ensure the stability of the connection between the truncated conical mold 51 and the mold sleeve 52, a limiting protrusion ring 512 is provided on the upper surface of the first connecting ring 511, and a limiting groove 522 for accommodating the limiting ring is provided at the bottom of the second connecting ring 521. Thus, when the mold sleeve 52 is installed on the truncated conical mold 51, the limiting protrusion ring 512 engages with the limiting groove 522, thereby ensuring the stability of the connection between the truncated conical mold 51 and the mold sleeve 52.

[0021] The support assembly 2 includes a hollow support base 21, a support platform 22 on the top of the support base 21, and a spring-loaded tabletop 6 on the support platform 22. A push rod 23 is installed in the support base 21, with the top of the push rod 23 extending through the support platform 22 and connecting to the spring-loaded tabletop 6. The push rod 23 is slidably connected to the support platform 22. A push plate 24 is installed at the bottom of the push rod 23 and slidably connected to the interior of the mounting base. Multiple first guide blocks 241 are installed on the side wall of the push plate 24. Multiple first guide grooves 211 are opened on the inner wall of the support base 21 and slidably connected to the first guide blocks 241. Finally, a drive motor 25 is installed on the side wall of the support base 21, and the output end of the drive motor 25 is located in the support base 21. A cam 26 is installed at the output end of the drive motor 25. When the support assembly 2 controls the bouncing tabletop 6 to bounce on the support assembly 2, the drive motor 25 is activated. The drive motor 25 controls the cam 26 to rotate in the support base 21. As the cam 26 rotates, it can push the push plate 24 to move in the support base 21, so that the bouncing tabletop 6 connected to the push rod 23 can bounce on the support base 21. At the same time, in order to ensure the stability of the push plate 24 when it moves in the support base 21, a plurality of first guide blocks 241 are provided on the side wall of the push plate 24. At the same time, a plurality of first guide grooves 211 that are slidably connected to the first guide blocks 241 are provided on the inner wall of the support base 21. In addition, in order to ensure the stability of the bouncing tabletop 6 on the support base 21, a support platform 22 is provided on the top of the support base 21.

[0022] Furthermore, in order to improve the stability of the push rod 23 during movement, a plurality of second guide blocks 231 are evenly arranged on the outer wall of the push rod 23, and a second guide groove 221 that is slidably connected to the second guide blocks 231 is provided at the sliding connection between the support platform 22 and the push rod 23.

[0023] Furthermore, in order to ensure the bouncing effect of the bouncing tabletop 6, an impact ring 7 is provided on the top of the support platform 22. In this way, when the bouncing tabletop 6 falls onto the support platform 22, the bouncing tabletop 6 collides with the impact ring 7, thus ensuring the bouncing effect of the bouncing tabletop 6.
