Description

Technical Field

[0001] This utility model relates to the field of crack-resistant mortar technology, specifically to a crack-resistant mortar fiber dispersion uniformity tester. Background Technology

[0002] Crack-resistant mortar is a type of mortar made by mixing a crack-resistant agent (made from polymer emulsion and admixtures), cement, and sand in a certain proportion. It can withstand certain deformations without cracking and has good crack resistance, bonding properties, weather resistance, and water resistance. It is widely used in the construction industry.

[0003] Existing methods for testing the uniformity of fiber dispersion in crack-resistant mortar mainly involve applying bending loads to the specimens and recording the load values ​​when cracks appear. When the fibers are uniformly dispersed, the specimens have higher crack resistance loads, finer cracks, and more uniform distribution. However, traditional crack-resistant mortars are mostly tested manually when undergoing bending crack resistance testing, and the testing can often only be performed on mortars with a specific curvature of the bending test piece.

[0020] Please see Figure 1-3A crack-resistant mortar fiber dispersion uniformity tester includes a tester body 1 and a metal template containing a specimen. The tester body 1 is equipped with a positioning mechanism for fixing the metal template and a bending mechanism for bending the specimen on the metal template. The fixing mechanism includes a placement groove 3 and positioning structures on both sides of the placement groove 3. The positioning structures include a positioning roller 4 and a positioning roller 5 for clamping and fixing one side of the metal template. The bending mechanism includes an arc-shaped bending component 6 for bending the metal template in an arc shape. The tester body 1 is also equipped with an adjustment mechanism for adjusting the arc-shaped bending component 6. The adjustment mechanism includes a turntable 8 for mounting the arc-shaped bending component 6 and a drive motor 9 for driving the turntable 8 to rotate. The tester body 1 is equipped with a central control unit 2. The tester body 1 serves as the structural carrier of the entire device, integrating core components such as the positioning mechanism, bending mechanism, and adjustment mechanism, providing mechanical support and a mounting foundation. The central control unit 2 is the control core of the device, responsible for coordinating the automation of positioning, bending, and adjustment actions. The system operates by controlling the start / stop and parameters of components such as the electric telescopic rod 12, drive motor 9, and telescopic electric support column 7 through a preset program. The placement slot 3 is used to place the metal sample containing the crack-resistant mortar specimen, providing a horizontal positioning reference surface to ensure the stability of the sample position during testing. Positioning roller 1 4 is fixed on the mounting part 10, serving as a reference surface on one side of the metal sample and providing support force. Positioning roller 2 5 is connected to the electric telescopic rod 12 through the mounting block 11, and cooperates with positioning roller 1 4 to clamp both sides of the metal sample, ensuring that the sample does not slip or shift during bending. The arc-shaped bending component 6 acts directly on the bottom of the metal sample, applying bending force through the arc surface to simulate the actual stress scenario of the crack-resistant mortar and test its crack resistance performance. The turntable 8 is equipped with multiple sets of telescopic electric support columns 7 and arc-shaped bending components 6. By rotating and switching bending components with different curvatures, the test parameters can be quickly adjusted to meet diverse testing needs. The drive motor 9 is the power source for the adjustment mechanism, driving the rotating roller 17 to rotate through gear transmission to achieve the angle control of the turntable 8.

[0021] Please see Figure 1 and Figure 2The main body 1 of the detector has a placement groove 3 for placing a metal sample at its center. Both sides of the placement groove 3 have mounting grooves. Multiple sets of guide rods 14 are installed inside the mounting grooves. Two sets of mounting components 10 are movably mounted on the upper limit of each guide rod 14. Positioning rollers 4 are mounted on the two sets of mounting components 10. Mounting blocks 11 are movably mounted on the upper limit of each mounting component 10. Positioning rollers 5 that cooperate with positioning rollers 4 are mounted on the mounting blocks 11. An electric telescopic rod 12 is mounted on each mounting component 10. A connecting piece 13 is located at the output end of the electric telescopic rod 12, and one end of the connecting piece 13 is connected to the outside of the mounting block 11. Multiple sets of return springs 15 are installed inside the mounting grooves, and one end of each return spring 15 is connected to the outside of the mounting components 10. The mounting grooves accommodate the guide rods 14, mounting components 10, return springs 15, and other components, providing guidance and support for the movement of the positioning rollers. The mounting components 10 carry positioning rollers 4 and are moved by electric telescopic rods. The telescopic rod 12 drives the mounting block 11 to open and close the positioning roller 4 and the positioning roller 5, thus clamping and fixing the metal sample. The electric telescopic rod 12 drives the mounting block 11 to move through its telescopic movement, adjusting the distance between the positioning roller 5 and the positioning roller 4 to achieve adaptive clamping of metal samples of different thicknesses. The connecting piece 13 transmits the driving force of the electric telescopic rod 12 and connects the mounting block 11 and the output end of the electric telescopic rod 12 to ensure synchronized action. When the curved bending piece 6 stops pushing the bottom of the metal sample, the spring force of the return spring 15 pushes the mounting piece 10 to reset, facilitating quick replacement of the metal sample and improving testing efficiency. The placement groove 3 provides a precise horizontal positioning benchmark. Combined with the dynamic clamping of the positioning roller 4 and the positioning roller 5, it can effectively eliminate the displacement deviation of the metal sample during the bending test, ensuring the consistency of the stress state of the crack-resistant mortar specimen, thereby making the fiber dispersion uniformity test results more accurate and reliable, and providing strong data support for quality assessment.

[0022] Please see Figure 3The center of the placement slot 3 has a slot communicating with the interior of the main body 1 of the detector. Inside the main body 1 of the detector is a mounting frame 16, on which a rotating roller 17 is rotatably mounted. A turntable 8 is mounted at the top of the rotating roller 17, and multiple sets of retractable electric support columns 7 are mounted on the turntable 8. Each set of retractable electric support columns 7 has an arc-shaped bending component 6 with a different curvature at its output end. A gear 18 is mounted on the rotating roller 17. Inside the main body 1 of the detector is a drive motor 9, and at its output end is a gear 19 that meshes with gear 18. The retractable electric support columns 7 support the arc-shaped bending components 6, and their height is adjusted by telescoping, allowing the arc-shaped bending components 6 to move out of the main body 1 through the slot and contact the bottom of the metal sample, applying bending force. The degree of bending can be controlled. The mounting frame 16 is fixed in place. The bearing housing of roller 17 provides rotational support, reduces swaying during rotation, and ensures accurate positioning of the curved component 6. Roller 17 connects turntable 8 and gear 18, transmitting the rotational power of drive motor 9 to ensure smooth rotation and accurate positioning of turntable 8. Gear 18 and gear 2 19 amplify torque through meshing transmission, ensuring stable and reliable rotation of turntable 8. At the same time, the speed can be adjusted by the gear ratio to improve positioning accuracy. Drive motor 9 is the power source for the adjustment mechanism, driving roller 17 to rotate through gear transmission to control the angle of turntable 8. Multiple sets of curved components 6 with different curvatures are set on turntable 8, which can be quickly switched by controlling the rotation of turntable 8 through drive motor 9 to meet diverse testing needs. It can test crack-resistant mortar of different specifications and application scenarios, expanding the applicability of the testing instrument.

[0023] Working principle: As the testing personnel place the metal sample containing the crack-resistant mortar specimen into the placement groove 3 of the main body 1 of the testing instrument, the placement groove 3 provides a horizontal positioning reference for the sample. After the main control terminal 2 is activated, the electric telescopic rod 12 retracts, pushing the mounting block 11 through the connecting piece 13, which in turn moves the positioning roller 5 towards the positioning roller 4. The two work together to clamp the two sides of the metal sample. This positioning process ensures that the sample remains stable during subsequent testing and will not slip or shift. The drive motor 9 starts, and through the meshing transmission of gear 18 and gear 2 19, it drives the rotating roller 17 to rotate, which in turn causes the turntable 8 to rotate. The turntable 8 is equipped with multiple sets of telescopic electric support columns 7 and curved bending parts 6 of different curvatures, which can be adjusted according to testing requirements. The turntable 8 rotates until the curved bending piece 6 of a suitable curvature is directly opposite the slot in the center of the placement groove 3. At this time, the telescopic electric support column 7 extends, pushing the curved bending piece 6 through the slot from inside the main body 1 of the testing instrument, contacting the bottom of the metal sample, and applying bending force to bend the metal sample into an arc shape, simulating the stress scenario of crack-resistant mortar in actual application. At the same time, the two sides of the metal sample being clamped will retract inward, and the return spring 15 will be compressed. When the test is completed, the telescopic electric support column 7 retracts, the curved bending piece 6 separates from the metal sample, and the return spring 15 releases its elastic force to push the mounting piece 10 to reset. As the positioning roller 1 4 and positioning roller 2 5 are released, the metal sample can be replaced and the next test can be performed.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
