Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a cement fluidity testing device. Background Art

[0002] Cement fluidity is a measure of the ability of cement paste to flow on its own without external force. It is an important indicator for evaluating the working performance of cement, especially in the preparation and construction of concrete. Workers test the cement fluidity data through cement fluidity tests.

[0003] The existing cement fluidity test is carried out using a separate glass plate. To ensure the accuracy of the test data, the glass plate needs to be leveled multiple times during the test. During leveling, the staff uses paper or thinner metal sheets to raise the height of the glass plate, and uses other objects to calibrate the glass plate to a horizontal level. During the test, this adjustment method is very likely to cause a sudden and substantial increase in force on other objects due to the pouring of cement, causing some other objects to accidentally break away from the support of the glass plate, thereby causing the failure of the cement fluidity test. This situation reduces the stability of the test device during the cement fluidity test to a certain extent.

[0004] Therefore, it is necessary to provide a new cement fluidity test device to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a cement fluidity testing device.

[0006] The cement fluidity test device provided by the utility model comprises a glass plate, a plurality of threaded columns are fixedly arranged at the bottom of the glass plate, and the outer surfaces of the plurality of threaded columns are respectively sleeved with adjustment mechanisms connected with the threads thereof;

[0007] The adjustment mechanism includes a support column, which is sleeved on the outer surface of the threaded column. The support column is threadedly connected to the threaded column. A connecting column is fixedly provided at the bottom of the support column. A limiting column is fixedly provided at the bottom of the connecting column. A circular frame is movably sleeved on the outer surface of the limiting column. Two limiting blocks movably connected to the outer surface of the connecting column are fixed inside the circular frame. Two limiting grooves are provided at the top of the limiting column. The outer surfaces of the two limiting blocks are movably connected to the inner surfaces of the two limiting grooves.

[0008] Preferably, a square frame is provided at the top of the glass plate, the bottom of the square frame is adhesively connected to the top of the glass plate, and a circular groove is provided at the top of the square frame.

[0009] Preferably, an overflow pipe communicating with the interior of the square frame is fixedly provided on one side of the outer surface of the square frame.

[0010] Preferably, scales with different diameter values ​​are drawn on the bottom of the glass plate.

[0011] Preferably, a cleaning plate is movably provided inside the square frame, and a power piece is fixedly provided on one side of the cleaning plate. The power piece extends out of the square frame away from one side of the cleaning plate, and the outer surface of the power piece is movably connected to the inner surface of the square frame.

[0012] Preferably, the power component includes a power column, one side of the power column is fixedly connected to one side of the cleaning plate, the power column extends out of the square frame away from the cleaning plate, the outer surface of the power column is movably connected to the inner surface of the cleaning plate, and a circular block is fixedly provided on the side of the power column away from the cleaning plate.

[0013] Preferably, a spring is sleeved on the outer surface of the power column, and two ends of the spring are respectively fixedly connected to the circular block and the opposite side of the square frame.

[0014] Preferably, the value of the scale (11) at the bottom of the glass plate (1) is a circle with a diameter of 60 mm to 350 mm.

[0015] Preferably, the bottom of the glass plate (1) is provided with a 60 mm diameter scale (11), a 100 mm diameter scale (11), and a 100 mm to 350 mm diameter scale (11), and the intervals between the 100 mm to 350 mm diameter scales (11) are 1 mm.

[0016] Preferably, four sector-shaped scales (11) with diameters ranging from 60 mm to 350 mm are drawn on the bottom of the glass plate (1), wherein scales (11) with intervals of cardinal numbers are opened between two sector-shaped diameters of 100 mm and 350 mm, and scales with intervals of even numbers are opened between the other two sector-shaped diameters of 100 mm and 350 mm.

[0017] Compared with the related art, the cement fluidity test device provided by the utility model has the following beneficial effects:

[0018] When the staff needs to adjust the level of the test device, the staff lifts the test device and rotates the circular frame under the glass plate so that the limit block inside the circular frame enters the limit groove of the limit column to complete the limiting of the limit block.

The staff can then conduct a cement fluidity test. This structure prevents the test device from releasing the connection between the circular frame and the limit column when conducting a cement fluidity test on the ground, prevents the circular frame from accidentally causing the limit column to drive the supporting column to rotate, and avoids the situation where the horizontal height of the test device changes, thereby improving the stability of the test device when conducting a cement fluidity test to a certain extent.

[0035] A level bubble 12 is provided inside the glass plate 1, through which it can be determined whether the test device is in a horizontal state, and at the same time, it is convenient for the staff to adjust the test device to a horizontal state. The square frame 6 is made of PVC transparent material, and the scale 11 on the glass plate 1 can be seen through the square frame 6. Figure 6 And attached Figure 7 The square frame 6 and the glass plate 1 are slotted and glued together to prevent cement from flowing out from the connection between the square frame 6 and the glass plate 1 when the test device is testing. At the same time, after the test is completed, the staff pours most of the cement from the overflow pipe 5, and then opens the square frame 6 to clean and collect the cement remaining on the top of the glass plate 1 and inside the square frame 6, which ensures that the cement slurry is not lost to a certain extent, and prevents the occurrence of differences in test data due to the loss of cement slurry; Embodiment 2

[0036] according to Figure 8 as well as Fig. 9 As shown, following the same structure as detailed in Example 1, the difference from Example 1 is that a cleaning plate 7 is movably provided inside the square frame 6, the cleaning plate 7 is movably provided inside the square frame 6, a power member is fixedly provided on one side of the cleaning plate 7, the power member extends out of the square frame 6 away from the side of the cleaning plate 7, the outer surface of the power member is movably connected to the inner surface of the square frame 6, the power member includes a power column 8, one side of the power column 8 is fixedly connected to one side of the cleaning plate 7, the power column 8 extends out of the square frame 6 away from the side of the cleaning plate 7, the outer surface of the power column 8 is movably connected to the inner surface of the cleaning plate 7, a circular block 9 is fixedly provided on the side of the power column 8 away from the cleaning plate 7, a spring 10 is sleeved on the outer surface of the power column 8, and both ends of the spring 10 are respectively fixedly connected to the circular block 9 and the side opposite to the square frame 6; Embodiment 3

[0037] according to Fig.10 as well as Fig.11 As shown, the same structure as described in the first embodiment is followed, and the difference from the first embodiment is that:

[0038] The bottom of the glass plate 1 is provided with a 60 mm diameter scale 11, a 100 mm diameter scale 11 and a 100 mm to 350 mm diameter scale 11, and the intervals between the 100 mm to 350 mm diameter scales 11 are 1 mm.

[0039] The scale 1 provided allows the staff to conduct fluidity tests of different specifications. Embodiment 4

[0040] according to Fig.12 as well as Fig.13As shown, the same structure as described in detail in the first embodiment is followed. The difference from the first embodiment is that four sector-shaped scales 11 with diameters of 60 mm to 350 mm are drawn on the bottom of the glass plate 1, wherein scales 11 with intervals of cardinal numbers are opened between two sector-shaped diameters of 100 mm and 350 mm, and scales 11 with intervals of even numbers are opened between the other two sector-shaped diameters of 100 mm and 350 mm.

[0041] By staggering the cardinal number scales 11 and the even number scales 11 , it is easier for the staff to observe the flowability data.

[0042] When the staff pours most of the cement out of the overflow pipe 5, the staff pushes the circular block 9 so that the circular block 9 drives the spring 10 to be in a compressed state. At the same time, the circular block 9 drives the cleaning plate 7 to move inside the test device through the power column 8. At the same time, the cleaning plate 7 cleans the residual cement inside the test device into the overflow pipe 5, and discharges it from the inside of the test device through the overflow pipe 5. There is no need to store and clean the test device. At the same time, the staff loosens the circular block 9 to release the drive on the spring 10. According to the stretchability of the spring 10, the circular block 9 drives the power column 8 to move, so that the power column 8 drives the cleaning plate 7 to reset. There is no need for the staff to manually reset. Through this structure, the staff can remove the square frame 6 to clean the glass plate 1. When the staff does not drive the circular block 9, the cleaning plate 7 is located on the side wall of the square frame 6, so the cleaning plate 7 will not block the staff's observation of the scale 11 on the glass plate 1.

[0043] The working principle of the utility model is as follows: when the staff needs to adjust the level of the test device, the staff lifts the test device and rotates the circular frame 16 under the glass plate 1, so that the limit block 17 inside the circular frame 16 enters the limit groove 15 of the limit column 14, and the limit of the limit block 17 is completed. Then the staff can rotate the circular frame 16, so that the circular frame 16 drives the limit column 14 to rotate through the limit block 17, and the limit column 14 drives the support column 3 to rotate through the connecting column 13, so that the support column 3 moves downward through the threaded column 2, and the horizontal adjustment of the test device is completed. Then The staff places the test device on the ground, so that the circular frame 16 drives the limit block 17 to move upward, so that the limit block 17 is separated from the limit groove 15 of the limit column 14 and is located on the outer surface of the connecting column 13. Then the staff can pour the cement from the circular groove 4 of the square frame 6 into the square frame 6. The staff observes the flow of cement in the test device after 30 seconds, and obtains the fluidity of the cement through the scale 11 inside the glass plate 1. After the test is completed, the staff releases the seal of the overflow pipe 5, pours the cement inside the square frame 6 out of the square frame 6 through the overflow pipe 5, and completes the cleaning of the cement inside the square.
