Description

Technical Field

[0001] This application relates to the field of brick compressive strength testing technology, and in particular to a brick rebound tester for testing the compressive strength of wall bricks. Background Technology

[0002] Wall tiles are suitable for the facade decoration of bathrooms, kitchens, and outdoor balconies. Applying wall tiles is an effective way to protect the wall from water splashes. In order to ensure the performance of wall tiles, it is necessary to test their performance through a compressive strength test, which is generally carried out using a brick rebound tester.

[0003] A search revealed that CN220829434U discloses a brick rebound hammer for testing the compressive strength of wall tiles. Through the combined use of a deflection shaft, a support, a threaded rod, and a level, the brick rebound hammer can deflect and open the support. Then, the threaded rod is rotated, causing it to extend from the support, with its end reaching below the bottom of the rebound hammer's housing and contacting the outside of the wall tile. The extension of the threaded rod is adjusted according to the level's position until the rebound hammer's housing remains vertical, thus ensuring the brick rebound hammer's vertical position during testing and improving detection accuracy.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist that need to be improved: Although the above-mentioned device can ensure stable operation during the detection process, the surface flatness of the wall tiles will greatly affect the detection value. Unevenness will cause the rebound value to be distorted, and the defects need to be polished or avoided, otherwise the rebound height cannot be accurately measured. Utility Model Content

[0005] This application provides a brick rebound tester for wall brick compressive strength testing to improve the following technical problems: Although the above-mentioned device can ensure stable operation during the testing process, the surface flatness of the wall brick will greatly affect the test value.

The punching hammer 6 is fixedly connected to the bottom of the vertical push shaft 5. The grinding assembly 7 is installed on the inside of the support base 3. A rebound assembly 8 is also provided on the outside of the vertical push shaft 5.

[0032] The operation panel 2 is used for manual operation touch commands, the support base 3 is used to vertically support the instrument housing 1, the compression spring 4 is used to drive the vertical push shaft 5 and the punching hammer 6 below to fix the kinetic energy to impact the wall tile surface, the vertical push shaft 5 is used to connect the punching hammer 6, the grinding assembly 7 is used to grind the surface of the wall tile, and the rebound assembly 8 is used to connect the vertical push shaft 5 and squeeze the compression spring 4 upward to the designated position, thereby providing fixed kinetic energy.

[0033] The grinding assembly 7 includes a sliding crossbeam 71, a stepper motor 72, a locking gear 73, and a grinding machine body 74. The sliding crossbeam 71 is slidably connected to the inner side of the support base 3. The stepper motor 72 is installed on the outer side of the sliding crossbeam 71. The locking gear 73 is installed on the outer side of the output end of the stepper motor 72 and is rotatably connected to the inner side of the sliding crossbeam 71. The grinding machine body 74 is installed in the middle of the sliding crossbeam 71 and is used to grind the impact surface of the wall tiles.

[0034] The rebound assembly 8 includes a fixed plate 81, a first cylinder 82, a lifting frame 83, an adjusting plate 84, and a second cylinder 85. The fixed plate 81 is fixedly connected inside the instrument housing 1. The first cylinder 82 is mounted on the surface of the fixed plate 81. The lifting frame 83 is fixedly connected above the output end of the first cylinder 82. The adjusting plate 84 is slidably connected to the inner side of the top protruding end of the lifting frame 83. The second cylinder 85 is mounted on the top of the lifting frame 83 and is fixedly connected to the surface of the adjusting plate 84.

[0035] The inner side of the support base 3 is also provided with a rack seat 9 that meshes with the external teeth of the locking gear 73.

[0036] The vertical push shaft 5 is also provided with limiting grooves 10 on both sides that are adapted to the size of the adjusting plate 84.

[0037] The bottom of the fixed plate 81 is also fixedly connected to a finely ground anti-detachment plate 11. The side of the finely ground anti-detachment plate 11 does not contact the vertical push shaft 5 on the inner surface of the limiting groove 10, and the top surface of the finely ground anti-detachment plate 11 is used to support the vertical push shaft 5 located at the top of the groove of the limiting groove 10.

[0039] The usage process of the brick rebound hammer for wall brick compressive strength testing in this embodiment of the application is roughly as follows:

[0040] The support base 3 is smoothly placed against the surface of the wall tile to be tested, ensuring that the instrument housing 1 remains vertical. The stepper motor 72 is activated via the operation panel 2, driving the locking gear 73 to move along the rack seat 9, causing the sliding crossbar 71 to slide laterally. The grinding body 74 automatically grinds the area of ​​the wall tile to be tested, eliminating surface unevenness. During the rebound pressing operation, the first cylinder 82 pushes the lifting frame 83 upward, causing the adjusting plate 84 to embed into the limiting groove 10 of the vertical push shaft 5. The second cylinder 85 finely adjusts the position of the adjusting plate 84, ensuring that the vertical push shaft 5 is precisely lifted, compressing the compression spring 4 to the preset deformation. The finely ground anti-detachment plate 11 supports the top of the limiting groove 10, preventing the vertical push shaft 5 from shifting. Then, the punch hammer 6 is released, the rebound assembly 8 quickly resets, the compressed spring 4 releases kinetic energy, pushing the vertical push shaft 5 and the punch hammer 6 to vertically impact the ground and smoothed brick surface. The displacement sensor 12 records the rebound height of the punch hammer 6, and the data is displayed in real time on the operation panel 2. Finally, repeat the operation, export the history of rebound value through operation panel 2, take the average value of multiple measurements, and calculate the compressive strength by combining it with the strength measurement curve.

[0041] The beneficial technical effects of the brick rebound hammer for wall brick compressive strength testing according to the embodiments of this application are roughly as follows:

[0042] This device is equipped with a grinding component 7. The grinding machine body 74 can grind the surface of the wall tiles before testing to ensure that the impact area is flat and eliminate errors caused by roughness or local defects of the tile surface. The sliding crossbar 71 can adjust the grinding range to adapt to tiles of different sizes. The rebound component 8 can precisely control the deformation of the compression spring 4 to ensure that the initial kinetic energy of each impact is the same. The displacement sensor 12 directly measures the deformation of the compression spring 4 and the rebound height of the impact hammer 6, which provides more accurate data and avoids human operation errors.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
