Description

Technical Field

[0001] The utility model relates to the field of measuring the fluidity of cement mortar, and particularly relates to a device for measuring the fluidity of cement mortar. Background Art

[0002] The fluidity of cement mortar represents a measure of the fluidity of cement mortar. Under a certain water addition amount, the fluidity of cement mortar depends on the water demand of cement, and the fluidity of cement mortar is represented by the average diameter of the spread of cement mortar on a flow table.

[0003] A device for measuring the fluidity of cement mortar is an instrument for detecting the fluidity of cement mortar. The prepared mortar is placed in the center of a disc tabletop, and then the disc tabletop vibrates up and down under the action of upper and lower cams. After the vibration ends, the mortar will spread on the disc tabletop. Measure the diameters of the bottom surface of the mortar in two mutually perpendicular directions, calculate the average value, and take the integer as the fluidity of the cement mortar at this water amount.

[0004] However, during the use of a conventional device for measuring the fluidity of cement mortar, it is necessary to use a caliper to measure the diameters of the bottom surface of the mortar in two mutually perpendicular directions, and the operation is relatively cumbersome. Once the measurement cannot be carried out in time, the cement mortar will continue to spread, which will affect the detection accuracy and needs to be improved. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a device for measuring the fluidity of cement mortar, which has the effect of facilitating the measurement of the fluidity value of cement mortar.

Specific embodiments

[0028] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0029] As Figure 1 shown, a cement mortar fluidity tester includes a base 1, a sliding rod 2, a disc tabletop 3, a conical cylinder 4 and a driving mechanism 5.

[0030] As Figure 1 shown, the base 1 is placed on the tabletop, the sliding rod 2 is vertically slidably connected to the base 1, the disc tabletop 3 is horizontally arranged at the upper end of the sliding rod 2, the conical cylinder 4 is placed at the central position of the disc tabletop 3, and the driving mechanism 5 is used to control the vertical reciprocating movement of the sliding rod 2.

[0031] As Figure 1 shown, the driving mechanism 5 includes a motor 51, a cam 52 and a roller 53. The motor 51 is arranged on the base 1, the cam 52 is arranged on the shaft of the motor 51, and the roller 53 is arranged at the lower end of the sliding rod 2 and abuts against the outer wall of the cam 52.

[0032] When it is necessary to detect the fluidity of cement mortar, the conical cylinder 4 is placed at the central position of the disc tabletop 3, and then the cement mortar is mixed well in the conical cylinder 4. Then control the motor 51 to work, and use the cooperation of the cam 52 and the roller 53 to control the vertical vibration of the sliding rod 2 and the disc tabletop 3. After the vibration ends, the cement mortar will spread on the disc tabletop 3. Finally, measure the diameters of the bottom surface of the cement mortar and the diameter in the direction perpendicular to it to complete the detection of the fluidity of the cement mortar.

[0033] As Figure 2 , Figure 3As shown in the figure, support rods 6 are provided around the disc tabletop 3. A measuring ruler 61 is horizontally slidably connected to the support rods 6. The measuring ruler 61 is in contact with the surface of the disc tabletop 3. At the same time, a clamping block 62 for abutting against the outer wall of the lower end of the conical cylinder 4 is provided on the upper end surface of the inner end of the measuring ruler 61.

[0034] As Figure 2 , Figure 3 , Figure 4 shown, a slider 63 is vertically slidably connected inside the support rod 6 above the measuring ruler 61. A magnet 64 for adsorbing the measuring ruler 61 is provided at the lower end of the slider 63. A pull rod 65 vertically penetrating the upper end surface of the support rod 6 is provided on the slider 63. A pull ring 66 is provided at the upper end of the pull rod 65. A spring 67 is sleeved on the pull rod 65 between the pull ring 66 and the support rod 6.

[0035] When placing the conical cylinder 4, push the measuring ruler 61 to slide inward in sequence, so that the clamping block 62 at the inner end of the measuring ruler 61 abuts against the outer wall of the lower end of the conical cylinder 4. Then, according to the verticality of the measuring ruler 61, the calibration and positioning of the conical cylinder 4 are realized, so that the conical cylinder 4 is at the center of the disc tabletop 3, ensuring the detection accuracy.

[0036] Subsequently, press the pull ring 66 to drive the pull rod 65 and the slider 63 to move downward. The slider 63 drives the magnet 64 to move downward and adsorb the measuring ruler 61, thereby realizing the fixation of the measuring ruler 61, ensuring that the conical cylinder 4 does not slide during the mixing process of the cement mortar, and ensuring the detection accuracy.

[0037] At the same time, when the cement mortar spreads on the disc tabletop 3, push the measuring ruler 61 to slide quickly in sequence, so that the inner end position of the measuring ruler 61 is at the outer edge of the spreading position of the cement mortar. Then, press the pull ring 66 to drive the pull rod 65 and the slider 63 to move downward. The slider 63 drives the magnet 64 to move downward and adsorb the measuring ruler 61, thereby realizing the fixation of the measuring ruler 61. Even if the cement mortar continues to spread, it will not push the measuring ruler 61 to slide, thus ensuring the detection accuracy.

[0038] Therefore, by setting the measuring rulers 61 that are independently slidably connected in four directions, the position of the measuring ruler 61 can be quickly adjusted after the cement mortar flows, so that the measuring ruler 61 is timely at the edge position of the cement mortar. Then, the readings and records are unified. The operation process is simple, and even if the cement mortar shows a continuous diffusion phenomenon, it does not affect the detection accuracy.

[0039] As Figure 2 , Figure 3 shown, the disc tabletop 3 includes a fixed tabletop 31 and a movable tabletop 32. A groove 33 for the movable tabletop 32 to be embedded is provided on the upper end surface of the fixed tabletop 31. A pressing block 34 for pressing the upper end surface of the movable tabletop 32 is rotatably connected to the fixed tabletop 31. A rubber pad 35 is provided on the lower end surface of the pressing block 34.

[0040] As Figure 2 , Figure 3 shown, a push rod 36 is vertically arranged on the lower end surface of the movable tabletop 32, and a through hole 37 for the push rod 36 to pass through is arranged on the movable tabletop 32.

[0041] After testing one group of cement mortar specimens, control the pressing block 34 to rotate so that the pressing block 34 disengages from the movable tabletop 32, and then push the push rod 36 to jack up the movable tabletop 32, then the disassembly of the movable tabletop 32 can be realized. Subsequently, place the new movable tabletop 32 in the groove 33 of the fixed tabletop 31, and rotate the pressing block 34 to realize the clamping and fixing of the movable tabletop 32. At the same time, under the action of the rubber pad 35, the clamping force on the movable tabletop 32 is further increased to realize the stable fixing of the movable tabletop 32.

[0042] At this time, the next group of specimens can be quickly tested. During the testing process, the disassembled movable tabletop 32 can be cleaned. The two movable tabletops 32 work alternately to realize the quick testing of many groups of specimens and improve the testing efficiency.

[0043] The specific embodiments are only explanations of the present invention, and they do not limit the present invention. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
