Description

Technical Field

[0001] This utility model relates to the field of compressive strength testing technology for building materials, and in particular to a compressive strength testing device for lightweight building materials. Background Technology

[0002] The compressive strength test of building materials is an experimental method for evaluating the performance of materials under pressure. It is mainly used to measure the maximum compressive load or stress that a material can withstand.

[0003] Patent CN220084581U discloses a pressure testing device for building materials. It includes a test chamber and a hydraulic cylinder. The test chamber has a protective door hinged to its front, with an observation window on its surface. The hydraulic cylinder is fixedly installed inside the test chamber, and its hydraulic rod is fixedly connected to a mounting base. A pressure head is fixedly connected to the bottom center of the mounting base via a pressure sensor. When using this patent for pressure testing of building materials, the building material is placed inside the test chamber, and then the hydraulic rod of the hydraulic cylinder is extended. The hydraulic rod drives the pressure head and two pressure plates to descend. The pressure sensor monitors the pressure on the building material and transmits the monitoring data to a display screen. However, this existing patent still has some shortcomings. Because the building material will crack and produce debris after being compressed using this patent, the debris at the bottom of the test chamber needs to be manually cleaned after the test. However, manual cleaning is time-consuming and may affect the start time of the next test. Furthermore, failure to clean the debris will cause the sample to be placed unevenly, affecting the actual pressure value that the material can withstand.

[0004] Therefore, there is a need to provide a compressive strength testing device for lightweight building materials with an automatic cleaning function. Utility Model Content

[0005] To overcome the drawback that the material cracks and produces debris after being compressed using the existing patent, the debris at the bottom of the test chamber needs to be manually cleaned after the test. However, manual cleaning takes a long time and may affect the start time of the next test. On the other hand, not cleaning will affect the pressure distribution during the next test, causing the sample to be placed unevenly and affecting the actual pressure value that the material can withstand. This utility model provides a lightweight building material compression resistance testing device with automatic cleaning function.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a lightweight building material compressive strength testing device, comprising a test chamber, a weighing plate, a support frame, an electric push rod, a pressure plate, a control panel, baffles, and a pull rod. The weighing plate is installed inside the test chamber, and the support frame is fixedly connected to the test chamber. An electric push rod is installed between the two support frames, and a pressure plate is installed on the telescopic rod of the electric push rod. The pressure plate is located inside the test chamber. A control panel is installed on the test chamber and is electrically connected to the electric push rod and the weighing plate. Two baffles are slidably arranged on the test chamber, and pull rods are fixedly connected to the baffles. The device also includes a mounting frame, an electric telescopic rod, and a scraper. The mounting frame is fixedly connected between the two support frames, and the electric telescopic rod is installed on the mounting frame. A scraper is installed on the telescopic rod of the electric telescopic rod, and the scraper is located inside the test chamber.

[0007] Furthermore, it is particularly preferred that the test box also includes a safety light curtain, an electric slide rail, an electric slider, and a controller. Two safety light curtains are installed on the test box, an electric slide rail is installed on the test box, two electric sliders are installed on the electric slide rail, a baffle is installed on adjacent electric sliders, and a controller is installed on the test box, with the controller electrically connected to the safety light curtains.

[0008] Furthermore, it is particularly preferred that the test box also includes a support plate, a clamping plate, a guide rod, and an adjusting rod. Two support plates are fixedly connected to the test box, and two guide rods are slidably arranged on the support plates. A clamping plate is fixedly connected between the two guide rods. The clamping plate is located inside the test box, and an adjusting rod is fixedly connected to the clamping plate. The adjusting rod is threadedly connected to the adjacent support plate and passes through the test box.

[0009] In addition, it is particularly preferred that a protective pad is included, with the protective pad embedded in the clamp.

[0010] In addition, it is particularly preferred that the device also includes an observation plate, which is embedded in the baffle.

[0011] In addition, it is particularly preferred that the adjusting rod also includes an anti-slip sleeve.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. The electric telescopic rod is activated by the control panel, which causes the telescopic rod to extend and shorten, and drives the scraper to move back and forth, thereby scraping off the building materials and debris generated during the test on the weighing plate, achieving the effect of automatic cleaning, thus ensuring the accuracy of the next test and shortening the time to start the subsequent test.

[0013] 2. When the safety light curtain does not detect the worker's hand, it sends a signal to the controller, causing the controller to drive two electric sliders on the electric slide rail to move inward. The inward movement of the electric sliders causes the baffle to move inward, thereby automatically closing the baffle and preventing debris from splashing out if the baffle is not closed.

[0014] 3. By rotating the adjusting rod, the two guide rods and clamps on the adjusting rod move inward, thereby aligning the building material so that the top surface of the building material can fully contact the pressure plate and ensure accurate data. Attached Figure Description

Detailed Implementation

[0022] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] Example 1: A compressive strength testing device for lightweight building materials, see reference. Figures 1-5As shown, the system includes a test chamber 1, a weighing plate 2, a support frame 3, an electric push rod 4, a pressure plate 5, a control panel 6, a baffle 10, and a pull rod 11. The weighing plate 2, a pressure-type load cell, is bolted to the bottom of the test chamber 1. Support frames 3 are welded to both sides of the test chamber 1. An electric push rod 4 is bolted between the upper parts of the two support frames 3. A pressure plate 5 is mounted on the telescopic rod of the electric push rod 4, located inside the test chamber 1. A pull rod 11 is bolted to the front top of the test chamber 1. The control panel 6 is electrically connected to the electric push rod 4 and the weighing plate 2. The front side of the test box 1 is symmetrically equipped with baffles 10 that slide left and right. A pull rod 11 is fixedly connected to the front side of the baffles 10. The test box 1 also includes a mounting frame 7, an electric telescopic rod 8 and a scraper 9. The mounting frame 7 is fixedly connected between the lower parts of the two support frames 3. The electric telescopic rod 8 is installed in the middle of the mounting frame 7 by bolt connection. The scraper 9 is installed on the telescopic rod of the electric telescopic rod 8. The scraper 9 is located inside the test box 1 and behind the pressure plate 5. The bottom surface of the scraper 9 is in contact with the top surface of the weighing plate 2.

[0024] See Figure 1 and Figure 3 As shown, it also includes an observation plate 21, which is embedded in the baffle 10.

[0025] When a compressive strength test is required on lightweight building materials, firstly, slide the baffle 10 outward using the pull rod 11, then place the building material on the weighing plate 2. Next, pull the baffle 10 back to its original position, and then activate the electric push rod 4 via the control screen 6. This causes the extension rod of the electric push rod 4 to extend and move the pressure plate 5 downward, thus conducting the compressive strength test on the building material. The weighing plate 2 records the pressure and other values ​​generated during the process and transmits the data to the control screen 6. After the test is completed, control the extension rod of the electric push rod 4 to retract, causing the pressure plate 5 to reset. Then, activate the electric telescopic rod 8 via the control screen 6, causing the extension rod of the electric telescopic rod 8 to extend and retract, and moving the scraper 9 back and forth. This scrapes away the building material and debris generated during the test from the weighing plate 2, achieving an automatic cleaning effect. This ensures the accuracy of the next test and shortens the start time of subsequent tests. After cleaning, control the extension rod of the electric telescopic rod 8 to retract, causing the scraper 9 to return to its original position. The above operation can be repeated for the next compressive strength test of the building material.

[0026] Example 2: Based on Example 1, refer to Figure 3As shown, it also includes a safety light curtain 12, an electric slide rail 13, an electric slider 14, and a controller 15. The front of the test box 1 is symmetrically equipped with safety light curtains 12 by bolt connection. The two safety light curtains 12 are located in front of the two baffles 10. The upper part of the test box 1 is equipped with an electric slide rail 13 by bolt connection. Two electric sliders 14 are installed on the electric slide rail 13. The baffles 10 are installed on the adjacent electric sliders 14. The top of the test box 1 is equipped with a controller 15 by bolt connection. The controller 15 is electrically connected to the safety light curtain 12.

[0027] When it is necessary to open the baffle 10, the electric slide rail 13 is activated, causing the two electric sliders 14 on the electric slide rail 13 to move outward. As the electric sliders 14 move outward, the baffle 10 moves outward. After the building materials are placed into the test chamber 1, when the operator's hand leaves the safety light curtain 12, the safety light curtain 12 sends a signal to the controller 15, causing the controller 15 to drive the two electric sliders 14 on the electric slide rail 13 to move inward. The electric sliders 14 move inward, causing the baffle 10 to move inward, thereby automatically closing the baffle 10 and preventing debris from splashing out if the baffle 10 is not closed. The observation plate 21 allows the operator to observe the situation inside the test chamber 1.

[0028] See Figures 3-6 As shown, it also includes a support plate 16, a clamping plate 17, a guide rod 18, and an adjusting rod 19. The support plate 16 is fixedly connected to both sides of the lower part of the test box 1. The guide rod 18 is slidably provided on both the front and rear parts of the support plate 16. The clamping plate 17 is fixedly connected between the ends of the two guide rods 18. The clamping plate 17 is located inside the test box 1. The adjusting rod 19 is fixedly connected to the outer side of the middle part of the clamping plate 17. The adjusting rod 19 is threadedly connected to the nearby support plate 16 and passes through the test box 1.

[0029] See Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, it also includes an anti-slip sleeve 22, which is fitted onto the handwheel of the adjusting rod 19.

[0030] See Figures 4-6 As shown, it also includes a protective pad 20, which is embedded in the inner side of the clamping plate 17.

[0031] When the building material is placed on the weighing plate 2, the adjusting rod 19 is rotated to move the two guide rods 18 and the clamping plate 17 inward, thereby aligning the building material so that the top surface of the building material can fully contact the pressure plate 5 to ensure accurate data. After alignment, the adjusting rod 19 is reversed to move the two guide rods 18 and the clamping plate 17 back to their original positions. The protective pad 20 reduces the pressure between the clamping plate 17 and the building material, preventing the clamping plate 17 from scratching the building material. The anti-slip sleeve 22 increases the friction between the worker's hand and the adjusting rod 19, making it easier for the worker to rotate the adjusting rod 19.

[0032] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
