[0001] This utility model belongs to the field of dry-mixed mortar performance testing technology, specifically relating to an automatic testing device for the anti-slip performance of dry-mixed mortar. Background Technology

[0002] Dry-mixed mortar is a dry mixture made from cementitious materials, dried fine aggregates, additives, and other components determined according to performance specifications, measured and mixed in a specific ratio at a professional manufacturing plant. When using it, simply add water or other compatible components at the application site according to the prescribed ratio. It is mainly used in masonry, plastering, flooring, waterproofing, and ceramic tile bonding, offering advantages such as high construction efficiency, stable quality, and reduced on-site dust pollution.

[0003] The slip resistance of dry-mixed mortar is a very important construction performance indicator, especially when used on walls (such as tile adhesive and plastering mortar). It measures the ability of mortar to resist sliding down a vertical surface due to its own weight. If the slip resistance is not up to standard, it will lead to problems such as uneven mortar layer thickness and hollow walls. Therefore, this application proposes a testing device that can automatically detect the slip resistance of dry-mixed mortar to provide accurate data for the production and use of dry-mixed mortar.

It should be understood that the data used in this way can be interchanged where appropriate, so as to the embodiments of this application described herein.

[0019] like Figure 1 As shown, the present invention provides an automatic testing device for the anti-slip performance of dry-mixed mortar, comprising a support mechanism 100, a test platform 200, a rotary driver 300, a clamp 400, and a moving driver 500. Specifically, the support mechanism 100 provides stable support for the overall testing device and includes a leveling function to ensure that the test platform 200 is horizontal before testing. The test platform 200 is rotatably mounted on the support mechanism 100. The rotary driver 300 connects the support mechanism 100 and the test platform 200 to adjust the tilt angle of the test platform 200 during testing, thereby facilitating the testing of the anti-slip performance of dry-mixed mortar under different tilt states. The clamp 400 and the moving driver 500 are both mounted on the test platform 200, wherein the clamp 400 is used to hold the test piece, and the moving driver 500 is used to provide a sliding force acting on the test piece. Based on this, the anti-slip capability of the test piece is evaluated by detecting the sliding state of the test piece and the magnitude of the sliding force.

[0020] For example, slippage of dry-mixed mortar can be understood as the sliding of an object on the vertical surface of a formed mortar layer. Anti-slip performance can characterize the ability of dry-mixed mortar to prevent an object from sliding on the mortar layer in a wet state. Based on this, the test specimen should include a substrate, a dry-mixed mortar layer, and a test block; wherein, the substrate is a concrete block, and the test block is a wall installation component such as a tile or wall panel.

[0021] Continue to refer to Figures 1-3 As shown, the support mechanism 100 includes a support platform 110 and support columns 120. Specifically, the support platform 110 is a circular frame platform, meaning that a hollow cavity is formed inside the support platform 110, and the test bench 200 is rotatably installed within this hollow cavity; support columns 120 are provided at each of the four corners of the support platform 110 to create clearance space below the support platform 110 to accommodate the rotation of the test bench 200. Before testing, the test bench 200 is held in a position driven by the rotary actuator 300. Figure 1 and Figure 3 The test platform 200 is positioned horizontally with the support platform 110 to facilitate the installation of the test piece. During testing, the test platform 200 rotates under the drive of the rotary driver 300 to... Figure 2 As shown in the figure, the test platform 200 rotates from a horizontal state to a vertical state, which enables the adaptive testing of the anti-slip performance of dry-mixed mortar. In addition, under the drive of the rotary driver 300, the test platform 200 can also be positioned at any angle from 0° to 90°, thereby facilitating the testing of the anti-slip performance of dry-mixed mortar at different tilt angles and ensuring the comprehensiveness of the test.

[0022] It is worth noting that each of the support columns 120 is configured as a telescopic structure capable of height adjustment, so that the support platform 110 can be leveled collaboratively by the support columns 120 at the four corners. Specifically, each support column 120 includes a column body and support feet spirally connected to the bottom of the column body. Based on this, by rotating the support feet, some of the support feet can be inserted into or removed from the column body, thereby changing the overall height of the support column 120. The four support columns 120 are independently adjustable to ensure that the support platform 110 is level, that is, to ensure that when the test platform 200 is horizontally aligned with the support platform 110, the initial angle of the test platform 200 is 0°.

[0023] In one specific embodiment, the rotary actuator 300 includes a rotation actuation part, the two ends of which are rotatably connected to the support mechanism 100 and the test platform 200, respectively. The rotation actuation part is configured to adjust the rotation angle of the test platform 200 relative to the support mechanism 100 by adjusting the distance between its two ends. Specifically, the rotation actuation part of the rotary actuator 300 can be an electric cylinder or a hydraulic cylinder, so as to adjust the distance between the two ends of the rotation actuation part by the extension and retraction drive of the electric cylinder or hydraulic cylinder, and can fix the test platform 200 at any rotation angle.

[0024] Continue to refer to Figure 3As shown, the fixture 400 includes a first fixture 410 and a second fixture 420 that are movable relative to each other. Specifically, the first fixture 410 is mounted on the test bench 200 and is used to hold the substrate in the test piece; the second fixture 420 is connected to the motion driver 500 and is used to hold the test block in the test piece. When the second fixture 420 is moved relative to the first fixture 410 by the motion driver 500, the test block moves relative to the substrate.

[0025] In this embodiment, we continue to refer to Figure 3 and Figure 5 As shown, the mobile actuator 500 includes a mobile execution part, which includes a slidingly mounted mobile guide rail 501 and a mobile slide block 502. The mobile slide block 502 is fixedly connected to the second clamp 420 via a connecting rod 503. The mobile guide rail 501 is configured to drive the second clamp 420 to perform a second-direction movement relative to the first clamp 410 by guiding the movement of the mobile slide block 502; wherein the second-direction movement is perpendicular to the first-direction movement.

[0026] For example, a dry-mixed mortar layer is applied to a concrete block with a cross-section of 40cm*20cm. Then, a compaction block with a cross-section of (100±1)mm*(100±1)mm and a mass of (5.00±0.015)kg is pressed onto the dry-mixed mortar layer for (30±5s). The concrete block is clamped and fixed by the first clamp 410, and the compaction block is clamped and fixed by the second clamp 420. The rotary actuator 300 drives the test platform 200 to rotate relative to the support mechanism 100 to the testing position. The movable actuator 500 drives the second clamp 420 through the connecting rod 503. The second clamp 420 moves relative to the first clamp 410 at a speed of 0.1 mm / min and a distance of 0.5 mm. During the movement, the driving force and driving time of the moving driver 500 are detected, or the moving speed is 0.1 mm / min and the moving time is 0.5 s. During the movement, the driving force of the moving driver 500 and the moving distance between the second clamp 420 and the pressure block are detected. Based on parameters such as moving distance, driving force and driving time, the anti-slip performance of the dry-mixed mortar layer at the current detection angle is evaluated.

[0027] Continue to refer to Figure 3 and Figure 4As shown, the first clamp 410 includes a fixed clamp 411 and a movable clamp 412, forming a first clamping space between the fixed clamp 411 and the movable clamp 412. The test bench 200 is provided with a first track 201 that guides the movable clamp 412 to move relative to the fixed clamp 411 in a first direction to adjust the size and position of the first clamping space. Specifically, multiple fixed clamps 411 are arranged equidistantly along the first direction, and two movable clamps 412 are arranged on the first track 201. Therefore, when clamping substrates of different sizes, multiple fixed clamps 411 clamp one end of the substrate, while two movable clamps 412 symmetrically clamp both sides of the substrate, ensuring the substrate's stability on the test bench 200. Of course, the clamping position of the substrate can also be adjusted based on the movement of the fixed clamps 411 and the movable clamps 412 on the first track 201 to flexibly meet actual testing needs.

[0028] Continue to refer to Figure 3 As shown, the test bench 200 is provided with a second track 202. The second track 202 is configured to guide the movement of the motion driver 500, thereby driving the second clamp 420 to move relative to the first clamp 410 in a first direction. This allows the second clamp 420 and the first clamp 410 to be misaligned in the first direction, facilitating the installation of the test piece. It should be noted that, in order to ensure the stability of the movement of the second clamp 420, such as... Figure 3 and Figure 6 As shown, a mounting frame 203 for mounting the second clamp 420 is provided on the test bench 200. The mounting frame 203 includes a vertical frame 204, a first horizontal frame 205, and a second horizontal frame 206. The vertical frame 204 is fixedly mounted on the test bench 200, the first horizontal frame 205 is fixedly mounted on the vertical frame 204, and the second horizontal frame 206 is slidably mounted on the first horizontal frame 205 along a second direction. The second clamp 420 is slidably mounted on the second horizontal frame 206 along a first direction. Based on this, when the mobile driver 500 moves along the second track 202 in the first direction, the second clamp 420 slides along the second horizontal frame 206. When the mobile driver 500 drives the second clamp 420 to move relative to the first clamp 410 in the second direction via the connecting rod 503, the second clamp 420 and the second horizontal frame 206 slide along the first horizontal frame 205, which can effectively ensure the stability of the movement of the second clamp 420, thereby avoiding the impact of clamp shaking on the test results.

[0029] It should be noted that both the first track 201 and the second track 202 can be electrically driven linear structures, such as linear motors, electrode lead screw structures, etc.

[0030] Furthermore, the automatic detection device for the anti-slip performance of dry-mixed mortar provided by this utility model further includes: a data acquisition module for acquiring the rotation driving angle of the rotary driver 300, the moving driving force of the moving driver 500, and the moving driving distance within a preset time; a data processing module for evaluating the anti-slip performance based on the data acquired by the data acquisition module and obtaining the evaluation result; and a display module for displaying the data acquired by the data acquisition module and the evaluation result.

[0031] The data acquisition module includes: an angle sensor mounted on the rotary driver 300 or the test platform 200; a force sensor mounted on the mobile driver 500; and a displacement sensor mounted on the mobile driver 500 or the second fixture 420.

[0032] In summary, the automatic testing device for the anti-slip performance of dry-mixed mortar provided by this utility model can, on the one hand, realize the automatic testing operation of the anti-slip performance of dry-mixed mortar, and on the other hand, automatically collect the testing parameters during the automatic testing operation, and automatically analyze and evaluate the anti-slip performance of the test specimen based on the collected parameters; in addition, it can also visualize the collected parameters and evaluation results.
