Description

Technical Field

[0001] This utility model relates to the field of building material testing technology, specifically to a rapid and accurate testing device for the compressive strength of building materials. Technical Background

[0002] In the field of construction engineering, the compressive strength of building materials is one of the key indicators for measuring material quality and the safety of engineering structures. Accurately testing the compressive strength of building materials is of great significance for ensuring the quality of construction projects. Among the existing technologies, the device disclosed in Chinese Patent Publication No. CN202023009005.0, by installing a protective cover on the lower surface of a fixed plate, can cover the outside of the building materials when the hydraulic press is used to test the compressive strength of the building materials, preventing the building materials from breaking and splashing outwards after excessive pressure, thus improving the safety of the device and making it quite practical.

[0003] However, this device has many shortcomings in its use. On the one hand, some testing equipment lacks an effective protective structure. During the testing process, building materials may break under pressure, causing fragments to fly, which can easily cause personal injury to operators and damage surrounding equipment. On the other hand, the device is not good at fixing building materials. During the testing process, the materials are prone to displacement, leading to inaccurate test data and affecting the reliability of the test results. In addition, after the device has finished testing, it is inconvenient to clean up the broken material residue, which usually requires manual cleaning. This not only increases the labor intensity of operators but also reduces the testing efficiency, making it unable to meet the needs of large-scale and rapid testing.

[0004] Therefore, developing a building material compressive strength testing device with good protective function, good fixing effect, easy cleaning and accurate and fast testing has become an urgent problem to be solved. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] As attached Figure 1 To be continued Figure 5 The aforementioned rapid and accurate testing equipment for the compressive strength of building materials includes a protective component 1, a fixed testing component 2, and a feeding component 3. The fixed testing component 2 is disposed inside the protective component 1, and the feeding component 3 is disposed at the bottom of the fixed testing component 2. Example

[0023] Specifically, the protective assembly includes a base 11, support columns 12, support plate 13, protective shell 14, outer shell 15, outer shell 16, and discharge pipe 17. Four sets of support columns 12 are symmetrically arranged at the top of the base 11. The function of the support columns 12 is to provide stable support for the support plate 13, fix the support plate 13 at a suitable height, and ensure the stability of the entire equipment structure. The support plate 13 is fixedly connected to the top of the support columns 12. The support plate 13 not only provides an installation platform for fixing the detection component 2 and the protective shell 14, but the sliding grooves at both ends of the plate also provide guidance for the movement of the clamping plate 23, ensuring that the clamping plate 23 can move smoothly.

[0024] The protective shell 14 is located at the top of the support plate 13. The protective shell 14 has positioning grooves at both ends. The positioning grooves cooperate with the sliding grooves of the support plate 13 to further limit the movement of the clamping plate 23. At the same time, the protective shell 14 and the door panel at one end connected by a hinge form a closed protective space to prevent material fragments from splashing during the testing process. The outer shell 15 is located at the top of the protective shell 14. The function of the outer shell 15 is to provide installation and protection space for the drive cylinder 24 and to prevent the drive cylinder 24 from being interfered with by external factors.

[0025] In addition, the outer casing 16 is located at the bottom of the support plate 13. The outer casing 16 provides installation and protection space for the drive motor 21 and the bidirectional threaded rod 22, preventing dust, impurities and other contaminants from entering and affecting the normal operation of the components. The feed pipe 17 is located at the end of the support plate 13 away from the outer casing 16. The function of the feed pipe 17 is to provide a channel for the fall of the crushed material residue after detection, so as to facilitate the introduction of the residue into the collection box 32. Example

[0026] Based on Example 1, in order to further prevent the material from shifting during the testing process, a fixed testing component is installed inside the protective component.

[0027] Specifically, the fixed detection component 2 includes a drive motor 21, a bidirectional threaded rod 22, a clamping plate 23, a drive cylinder 24, a pressure plate 25, a mounting plate 26, a damper 27, a spring 28, and a placement plate 29. The drive motor 21 is located at one end of the outer shell 16 and serves as a power source. Its output end is connected to the bidirectional threaded rod 22, which can drive the bidirectional threaded rod 22 to rotate. The bidirectional threaded rod 22 is symmetrically arranged at the output end of the drive motor 21. The outer end of the bidirectional threaded rod 22 is symmetrically provided with clamping plates 23. When the bidirectional threaded rod 22 rotates, it can drive the clamping plates 23 on both sides to move in opposite directions along the sliding groove of the support plate 13 and the positioning groove of the protective shell 14, thereby realizing the clamping or releasing of the building materials.

[0028] The drive cylinder 24 is located inside the outer casing 15. The bottom end of the drive cylinder 24 is connected to the pressure plate 25. The drive cylinder 24 can provide stable pressure, pushing the pressure plate 25 downward to apply pressure to the building material placed on the placement plate 29 for compressive strength testing. The pressure plate 25 is located at the bottom end of the drive cylinder 24 and is in direct contact with the building material, so as to evenly transfer the pressure generated by the drive cylinder 24 to the building material and ensure the accuracy of the test. The mounting plate 26 is located at the top of the support plate 13. The mounting plate 26 provides the mounting base for the damper 27 and fixes the damper 27 stably on the support plate 13. Four sets of dampers 27 are symmetrically arranged at the top of the mounting plate 26. The top of the damper 27 is connected to the placement plate 29. The damper 27 can play a buffering role during the test, slowing down the rate of pressure change and preventing the material from breaking instantly due to a sudden increase in pressure. At the same time, it works with the spring 28 to enhance the buffering effect.

[0029] In addition, spring 28 is sleeved on the outer end of damper 27. The two ends of spring 28 are in contact with mounting plate 26 and placement plate 29 respectively. Spring 28 is elastic and can produce elastic deformation when placement plate 29 is subjected to pressure, further assisting damper 27 in buffering and shock absorption, and ensuring the stability of the testing process. Placement plate 29 is set on top of damper 27. Placement plate 29 is used to place building materials to be tested. The anti-slip texture on its top can increase the friction between the material and placement plate 29, preventing the material from sliding during the testing process. The arc-shaped edge at the edge can prevent material residue from falling from the edge of placement plate 29.

[0030] It should be noted that when the drive cylinder 24 is activated, its piston rod extends slowly at a set rate, pushing the pressure plate 25 vertically downward. After the lower surface of the pressure plate 25 contacts the upper surface of the building material to be tested, the pressure generated by the drive cylinder 24 is evenly transmitted to the material surface as the piston rod continues to extend. Because the lower surface of the pressure plate 25 is precision polished, local pressure concentration can be avoided to prevent premature material breakage, ensuring that the test data accurately reflects the overall compressive strength of the material.

[0031] Real-time monitoring: The drive cylinder 24 integrates a pressure sensor, which can collect the pressure value inside the cylinder in real time and convert the data into an electrical signal to be transmitted to the matching control system. The control system's display screen will dynamically display the real-time pressure value, and the operator can intuitively observe the pressure change trend. At the same time, the system will automatically record the pressure data and form a pressure-time curve, providing a basis for subsequent test result analysis.

[0032] Specifically, the feeding assembly 3 includes a second drive motor 31, a collection box 32, an electric push rod 33, a push plate 34, and a telescopic column 35. The second drive motor 31 is located at the top of the base 11, and its output end is connected to the rotating shaft. The second drive motor 31 can drive the rotating shaft to rotate, thereby driving the collection box 32 to rotate. The collection box 32 is connected to the output end of the second drive motor 31 through the rotating shaft. A partition plate is provided in the middle of the collection box 32. The collection box 32 is used to collect the material residue after testing. The partition plate can divide the inside of the collection box 32 into multiple areas, which is convenient for classifying and collecting material residue of different batches or different types. At the same time, the collection box 32 can rotate under the drive of the second drive motor 31, which is convenient for aligning different areas with the feeding pipe 17 for residue collection.

[0033] The electric push rod 33 is installed on the inner wall of the protective shell 14. One end of the electric push rod 33 is connected to the push plate 34. The electric push rod 33 can provide linear driving force to push the push plate 34 to move in the horizontal direction. The push plate 34 is installed at one end of the electric push rod 33. Under the push of the electric push rod 33, the push plate 34 can push the detected crushed material residue on the placement plate 29 to the feed pipe 17 to realize the automatic cleaning of the residue.

[0034] In addition, telescopic columns 35 are symmetrically arranged on both sides of the electric push rod 33. One end of the telescopic column 35 is fixedly connected to the inner wall of the protective shell 14, and the other end of the telescopic column 35 is fixedly connected to one end of the push plate 34. The telescopic column 35 can play a guiding and supporting role during the movement of the push plate 34, ensuring that the push plate 34 always moves horizontally, avoiding tilting or deviation of the push plate 34 during the movement, and ensuring the effect of residue cleaning.

[0035] It should also be noted that the building materials used in this application may include small and medium-sized block building materials, large component building materials, and special functional building materials, etc. Figure 1In this embodiment, the building material is described as a small to medium-sized block building material. Of course, other types of building materials can also adopt a similar structure, which will not be elaborated on later.

[0036] Understandable, Figure 1 The diagram only schematically illustrates some of the components included in the testing equipment; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, testing equipment can also include, compared to Figure 1 More or fewer parts.

[0037] In actual use, the operator opens the door panel of the protective shell 14 and places the building material to be tested steadily on the top of the placement plate 29. When placing the material, ensure that the center of the material is roughly aligned with the center of the placement plate 29. The anti-slip texture on the top of the placement plate 29 increases the friction between the material and the placement plate 29, preventing the material from sliding during subsequent operations. At the same time, the arc-shaped edge of the placement plate 29 can prevent the material from falling accidentally.

[0038] When the power supply to the drive motor 21 is turned on, the drive motor 21 starts and outputs rotational power, which drives the bidirectional threaded rod 22 to rotate around its own axis through its output end. Since the clamping plates 23 symmetrically arranged at the outer end of the bidirectional threaded rod 22 are connected to the bidirectional threaded rod 22 by threads, and the surface of the bidirectional threaded rod 22 is machined with two sections of threads with opposite directions, under the rotation of the bidirectional threaded rod 22, the two sets of clamping plates 23 move towards each other along the sliding grooves at both ends of the support plate 13 and the positioning grooves at both ends of the protective shell 14.

[0039] Continuously observe the movement of the clamping plates 23. When the inner walls of the two sets of clamping plates 23 are tightly fitted to both sides of the building material to be tested, turn off the drive motor 21. At this time, the clamping plates 23 maintain the clamping state under the threaded locking action of the bidirectional threaded rod 22, and stably fix the building material on the placement plate 29 to prevent the material from shifting during the compressive strength test and ensure accurate test data.

[0040] Close the door panel of the protective shell 14 to form a closed protective space with the protective shell 14 and the door panel. Then, turn on the power to the drive cylinder 24 inside the outer shell 15. After the drive cylinder 24 is started, the piston rod at its bottom end slowly extends and pushes the pressure plate 25 to move downward in the vertical direction.

[0041] The pressure plate 25 continues to move downward until its lower surface is in complete contact with the upper surface of the building material to be tested. At this time, the drive cylinder 24 applies stable pressure to the pressure plate 25 through the piston rod according to the preset test pressure parameters. The pressure plate 25 transmits the pressure evenly to the surface of the building material to test the compressive strength of the material.

[0042] During the application of pressure, the building material generates a downward reaction force on the placement plate 29. The placement plate 29 transmits the reaction force to the four sets of dampers 27 connected at the top. The dampers 27 use their own damping characteristics to slow down the rate of pressure change. At the same time, the springs 28 sleeved on the outer end of the dampers 27 are compressed by the placement plate 29 and undergo elastic deformation, further absorbing the pressure impact and playing a buffering and shock absorption role. This prevents the material from breaking instantly due to a sudden increase in pressure, ensures a stable testing process, and ensures that the test data can accurately reflect the actual compressive strength of the material.

[0043] After the pressure test is completed, if the building material breaks under pressure, first control the piston rod of the drive cylinder 24 to retract, driving the pressure plate 25 to move upward and reset, away from the broken material residue, and then open the door panel of the protective shell 14 again.

[0044] When the power supply to the electric push rod 33 on the inner wall of the protective shell 14 is turned on, the electric push rod 33 starts and its movable end extends, pushing the push plate 34 to move horizontally toward the feed pipe 17 on the support plate 13. During this process, the telescopic columns 35 symmetrically arranged on both sides of the push plate 34 extend synchronously with the push plate 34, providing guidance and support for the push plate 34, preventing the push plate 34 from tilting or deviating, and ensuring that the push plate 34 can smoothly push the crushed residue on the placement plate 29.

[0045] The pusher plate 34 pushes the crushed residue to the edge of the support plate 13. The residue falls through the internal channel of the feed pipe 17. If the residue needs to be classified and collected, the power supply of the second drive motor 31 can be turned on. The second drive motor 31 drives the rotating shaft to rotate, and the rotating shaft drives the collection box 32 to rotate synchronously. The appropriate collection chamber in the collection box 32 is rotated to the position directly below the feed pipe 17, so that the residue falls accurately into the corresponding collection chamber.

[0046] After the residue is collected, the movable end of the electric push rod 33 is retracted, which drives the push plate 34 and the telescopic column 35 to reset. The drive motor 31 is turned off, completing a complete building material compressive strength test and subsequent cleaning process. The equipment is then restored to standby mode and can be used for the next test operation.

[0047] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
