Description

Technical Field

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

[0002] During the production and processing of building materials, it is necessary to test the compressive strength of the materials to determine their qualification status. Different materials have different compressive strengths, and the application of pressure often causes the materials to crack. The materials are prone to producing residues that fly everywhere under pressure.

[0003] A search revealed that utility model patent CN221260689U discloses a device for testing the compressive strength of bridge engineering building materials. Through the cooperation of a connecting rod and a blocking mechanism, the building materials can be blocked during testing, preventing debris from flying everywhere. This is not only convenient but also reduces production costs and energy consumption, effectively improving the device's applicability. Furthermore, the cooperation of a linear guide rail and a cleaning mechanism allows for effective debris removal, enhancing testing efficiency and solving the problems of low applicability and inconvenience in debris removal found in existing devices.

[0004] Although the aforementioned device can test the compressive strength of building materials, in actual testing, when the tested material cracks, although some debris will fly due to pressure, some debris will still adhere to the surface of the tested material because the pressure is insufficient to fly. Since this debris cannot be effectively collected, when the tested material is subsequently removed, this debris will adhere to the hands of the relevant testing personnel or fall directly into the testing environment, thus causing unnecessary pollution.

[0005] Therefore, it is necessary to invent a device for testing the compressive strength of building materials to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a device for testing the compressive strength of building materials. This device can clean up any unsplashed solid debris from the surface of the tested material after testing, thus preventing solid debris from falling into the work environment or adhering to the hands of testing personnel during subsequent removal. This is more convenient in actual use and addresses the problem mentioned in the background art: during actual testing, although some debris may splash due to pressure after the tested material cracks, some debris remains adhering to the surface of the tested material due to insufficient pressure. Since this debris cannot be effectively collected, it will adhere to the hands of testing personnel or fall directly into the testing environment when the tested material is subsequently removed, causing unnecessary pollution.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a device for testing the compressive strength of building materials, comprising:

[0008] A protective collection mechanism is used to block and collect debris that splashes during the compressive strength test.

[0009] A pressure testing mechanism, wherein the pressure testing mechanism is used to apply pressure to the material being tested; and

[0010] The test material support mechanism includes a mounting plate located at the top of the inner side of the chamber. Multiple support columns are evenly fixedly arranged on the outer side of the bottom of the mounting plate. The multiple support columns are fixedly arranged at the bottom of the inner cavity of the chamber. A drive motor is fixedly arranged at the center of the bottom of the mounting plate. A support turntable is rotatably sleeved on the top plate of the mounting plate through a bearing. The output shaft of the drive motor extends to the top of the mounting plate and is fixedly connected to the support turntable. An anti-slip pad is adhered to the top of the support turntable.

[0011] According to at least one embodiment of the building materials compressive strength testing device of the present disclosure, the protective collection mechanism includes a box, a chip discharge channel is provided in the middle of the front of the box, a protective cover is fixedly provided on the top of the box, and two mutually symmetrical protective doors are movably connected to the front of the protective cover by hinges.

[0012] According to at least one embodiment of the building materials compressive strength testing device of the present disclosure, a guide plate is fixedly installed in the middle of the inner side of the box, the guide plate is fixedly sleeved on the outside of four supporting columns, guide blocks are fixedly installed on both sides of the top of the guide plate, the guide blocks are fixedly connected to the inner wall of the box, a pad is fixedly installed on the front of the box, and a collection bucket is placed on the top of the pad.

[0013] According to at least one embodiment of the building materials compressive strength testing device of the present disclosure, the pressure testing mechanism includes a hydraulic cylinder fixedly disposed on the top of the protective cover, and a hydraulic power component is connected to the hydraulic cylinder.

[0014] According to at least one embodiment of the building materials compressive strength testing device of the present disclosure, an upper pressure plate is fixedly provided at the bottom end of the output shaft of the hydraulic cylinder, a plurality of limit pins are uniformly slidably provided through the top of the upper pressure plate, a lower pressure plate is fixedly provided at the bottom end of the plurality of limit pins, and a pressure sensor is fixedly provided at the top of the lower pressure plate.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This invention features a material support mechanism. After testing, the drive motor is energized, causing the support turntable to rotate continuously. This rotation causes the material to be placed on top of the anti-slip mat to rotate synchronously. During rotation, debris adhering to the surface of the material and falling onto the top of the turntable are thrown off by centrifugal force. The material itself remains in place due to friction with the anti-slip mat. The drive motor is then stopped, and the cleaned material is removed from the top of the anti-slip mat. Compared to existing technologies, this invention allows for the cleaning of any unsplashed solid debris from the surface of the material after testing, preventing it from falling into the work environment or sticking to the hands of testing personnel during subsequent removal. This makes it more convenient in practical use. Attached Figure Description

[0025] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0026] Figure 1 This is a schematic diagram of the overall structure of a building materials compressive strength testing device according to one embodiment of the present disclosure.

[0027] Figure 2 This is a schematic diagram of the protective collection mechanism 1 of a building materials compressive strength testing device according to one embodiment of the present disclosure.

[0028] Figure 3 This is a schematic diagram of the pressure testing mechanism 2 and the material support mechanism 3 of a building material compressive strength testing device according to one embodiment of the present disclosure.

[0029] like Figures 1-3 As shown, the compressive strength testing device for building materials disclosed herein may include components such as a protective collection mechanism 1, a pressure testing mechanism 2, and a material support mechanism 3.

[0030] like Figure 2As shown in this disclosure, the protective collection mechanism 1 includes a box 11. A chip removal channel is provided in the center of the front of the box 11. A protective cover 12 is fixedly installed on the top of the box 11. Two symmetrical protective doors 13 are movably connected to the front of the protective cover 12 via hinges. A guide plate 14 is fixedly installed in the center of the inner side of the box 11. The guide plate 14 is fixedly sleeved on the outside of four supporting columns 32. Guide blocks 15 are fixedly installed on both sides of the top of the guide plate 14. The guide blocks 15 are fixedly connected to the inner wall of the box 11. A pad 16 is fixedly installed on the front of the box 11. A collection bucket 17 is placed on the top of the pad 16.

[0031] Therefore, after the material being tested breaks, the debris generated falls onto the top of the guide plate 14 and can be discharged through the debris discharge channel under the guidance of the guide plate 14 and the guide block 15, and then falls into the inside of the collection bucket 17 under the action of gravity and is collected.

[0032] like Figure 3 As shown, in a preferred embodiment, the pressure detection mechanism 2 includes a hydraulic cylinder 21 fixedly mounted on the top of the protective cover 12. A hydraulic power component is connected to the hydraulic cylinder 21. An upper pressure plate 22 is fixedly mounted at the bottom end of the output shaft of the hydraulic cylinder 21. Multiple limit pins 23 are uniformly slidably disposed through the top of the upper pressure plate 22. A lower pressure plate 24 is fixedly mounted at the bottom end of the multiple limit pins 23. A pressure sensor 25 is fixedly mounted on the top of the lower pressure plate 24.

[0033] Therefore, after the material to be tested is placed on top of the anti-slip mat 35, the hydraulic power assembly provides power to the hydraulic cylinder, causing the hydraulic cylinder 21 to move the upper pressure plate 22 downward. When the upper pressure plate 22 moves downward, it moves the lower pressure plate 24 downward through the limit pin 23 until the lower pressure plate 24 is in contact with the top of the material to be tested. Subsequently, as the output shaft of the hydraulic cylinder 21 continues to move downward, the upper pressure plate 22 slides down along the limit pin 23 and presses on the top of the pressure sensor 25. The pressure sensor 25 continuously detects the pressure applied by the hydraulic cylinder 21. At the same time, the pressure applied by the hydraulic cylinder 21 also acts on the material to be tested through the pressure sensor 25 and the lower pressure plate 24. The material to be tested can be viewed through the protective door 13 made of tempered glass. When the material to be tested breaks, the hydraulic cylinder 21 drives its output shaft to reset.

[0034] It should also be noted that the pressure detection mechanism 2 is a solution already disclosed in the prior art and is not a necessary technical feature of this application. Therefore, this application will not elaborate on the specific model of the pressure sensor 25 and the other components connected to it.

[0035] like Figure 3As shown in this disclosure, the material support mechanism 3 includes a mounting plate 31 located at the top of the inner side of the housing 11. Multiple support columns 32 are evenly fixedly arranged on the outer side of the bottom of the mounting plate 31. The multiple support columns 32 are all fixedly arranged at the bottom of the inner cavity of the housing 11. A drive motor 33 is fixedly arranged at the center of the bottom of the mounting plate 31. A support turntable 34 is rotatably sleeved on the top plate of the mounting plate 31 through a bearing. The output shaft of the drive motor 33 extends to the top of the mounting plate 31 and is fixedly connected to the support turntable 34. An anti-slip pad 35 is adhesively arranged on the top of the support turntable 34.

[0036] Therefore, after the test is completed, the drive motor 33 is powered on, and the drive motor 33 drives the supporting turntable 34 to rotate continuously. When the supporting turntable 34 rotates, it drives the test material placed on the top of the anti-slip pad 35 to rotate synchronously. During the rotation, the debris attached to the surface of the test material and the debris that falls on the top of the supporting turntable 34 are thrown away under the action of centrifugal force. The test material cannot fall off due to the friction between it and the anti-slip pad 35. Then the drive motor 33 is stopped, and the cleaned test material is removed from the top of the anti-slip pad 35. Compared with the existing technology, it is possible to clean up the solid debris that has not been splashed on the surface of the test material after the test is completed, thereby avoiding solid debris from falling into the working environment or adhering to the hands of relevant test personnel when it is removed later. It is more convenient in actual use.

[0037] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0038] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
