Description

Technical Field

[0001] The invention relates to the technical field of building material detection, and in particular to a wear-resistant detection device for building materials used in construction design. Background Art

[0002] In the construction industry, construction design and the selection of building materials are inseparable, and they together determine the final quality, function and service life of the construction project. Every decision made in the construction design stage has a profound impact on the selection of materials, and the performance characteristics of building materials in turn affect the implementation of the design and the final effect. The relationship between the two is not only reflected in the implementation of the design, but also in how to achieve the best performance and function match through scientific material selection and reasonable design concepts.

[0003] The core goal of architectural design is to ensure the functionality, stability and safety of buildings, and building materials are the basis for achieving this goal. Designers select appropriate materials to meet design requirements based on the nature of the building's use, environmental conditions and expected functions. For example, when designing floors or walls with high wear resistance requirements, designers must take into account the material's wear resistance, compression resistance and other properties to ensure that it can withstand friction and wear in long-term use and maintain the stability and safety of the building. The wear resistance of building materials is a key indicator for evaluating their quality and applicability. Especially in high-intensity use environments, the long-term stability and wear resistance of building materials directly affect the safety and durability of the building.

[0004] Traditional testing equipment usually uses a certain amount of abrasive for testing, during which the friction and wear levels are relatively constant. Since the friction contact area and friction force remain relatively stable, this test method is difficult to truly reproduce the variable friction environment that building materials may encounter in actual use. In actual applications, the friction of materials is often affected by factors such as abrasive density and contact area. Therefore, a single test condition cannot fully reflect the true wear resistance of the material. Summary of the invention

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] refer to Figure 1-Figure 13, a wear-resistant testing device for building materials used in construction design, comprising:

[0054] Detection bracket 100;

[0055] A detection box 101 is arranged on the detection bracket 100, a detection platform 102 is arranged in the detection box 101, and a fixing part 103 for fixing the detection member is arranged on the detection platform 102;

[0056] The container 104 disposed on the top of the detection box 101 is used to contain abrasives, and a discharge port 105 is provided at the bottom of the container 104;

[0057] A discharge shaft 106 is disposed in the container 104, and a plurality of discharge plates 107 are connected to the outer wall of the discharge shaft 106, and a discharge cavity 108 is formed between every two adjacent discharge plates 107;

[0058] A pressure plate 109 disposed on the detection bracket 100;

[0059] An adjusting component disposed between the discharge shaft 106 and the discharge chamber 108, for adjusting the volume of the discharge chamber 108 for accommodating abrasives;

[0060] A moving component disposed between the detection bracket 100 and the pressure plate 109, used to move the pressure plate 109 up and down, and the moving component can synchronously move the position of the container 104 when moving the pressure plate 109;

[0061] A shaking component provided between the detection bracket 100 and the detection platform 102, used for shaking the detection platform 102, the shaking component can shake the detection platform 102 horizontally when the pressure plate 109 moves downward to a preset position;

[0062] The discharge shaft 106 can rotate during the process of the container 104 moving from point a to point b;

[0063] The adjusting component can adjust the volume of the discharge cavity 108 for accommodating the abrasive when the container 104 moves to a preset position;

[0064] By setting up the testing platform 102, when in use, building materials such as tiles, gypsum boards, and wooden boards that need to be tested for wear resistance can be placed in the testing platform 102, and the fixed part 103 thereon can be used to limit and fix the test piece, and abrasives such as sand grains and corundum can be filled into the container 104. Suitable abrasives are selected according to the test requirements, and the abrasives are stored in the container 104. Specifically, the operator can use the moving parts to move the position of the pressure plate 109 downward. When the pressure plate 109 moves downward close to the test piece in the testing platform 102, the set container 104 can move synchronously. The container 104 moves along the path of the testing box 101. During this process, the discharge shaft 106 set can rotate to drive the discharge plate 107 thereon to rotate. The abrasive stored in the discharge cavity 108 formed between every two adjacent discharge plates 107 can be released into the testing platform 102 as the discharge shaft 106 rotates, and the abrasive is evenly discharged to the surface of the testing platform 102. After the pressure plate 109 moves the position of the abrasive downward and applies a certain pressure to the abrasive, the moving part stops, and the shaking part set at this time starts to work, driving the detection platform 102 to shake horizontally. During the shaking process of the detection platform 102, the surface of the detection piece and the abrasive produce relative movement, so that the abrasive rubs evenly on the surface of the detection piece, which can effectively simulate the friction environment that the material may encounter in actual use. Through the horizontal shaking of the detection platform 102, the abrasive can fully contact the surface of the detection piece, so as to evaluate the wear resistance of the material under relatively uniform friction conditions. After continuously shaking the detection platform 102 for a period of time, the position of the moving pressure plate 109 can be reset upward by the moving part, so that the pressure plate 109 leaves the abrasive and the detection piece. During this process, the shaking part stops working and the container 104 is reset to the origin. After cleaning the abrasive on the detection piece, the wear state of the building material can be clearly observed. At this time, the operator can selectively, such as replacing the building material, cleaning the abrasive and continuing to perform another round of wear resistance testing on the building material. Since the adjustment component is set to adjust the volume of the discharge chamber 108 when the container 104 moves to the preset position for the first time, when the test is performed again, the volume of the discharge chamber 108 is increased when the container 104 moves along the test box 101 again. When the container 104 passes the test piece, the amount of abrasive released this time will be greater than the amount of abrasive released last time, so that the test piece is subjected to more abrasive in this round of testing. By analogy, by gradually increasing the amount of abrasive, the wear resistance of the material under high abrasive density conditions can be simulated, and its adaptability and performance under different friction intensity environments can be further evaluated. This design of dynamically adjusting the volume of the discharge chamber 108 can not only realize the gradually increasing abrasive release, but also provide more accurate and comprehensive wear resistance tests for various types of building materials by flexibly adjusting the range and variation of the discharge amount.At the same time, such a gradual loading method can help study the wear resistance of materials under different load conditions and provide a scientific basis for selecting suitable materials in engineering applications. After completing multiple rounds of tests, operators can record and analyze data based on the wear state of the test piece, such as key indicators such as surface wear depth, volume loss rate or mass reduction. For the test data of different materials, combined with parameters such as abrasive amount and friction time, a complete material wear resistance evaluation report can be generated. After multiple rounds of wear resistance tests on a building material, when the volume of the discharge chamber 108 is increased to the maximum and the last round of tests is completed, the building material can be replaced as a test piece. When replacing the building material as a test piece, the wear resistance test will be carried out in a manner where the amount of abrasive is gradually reduced. Through this gradually decreasing abrasive release method, the wear resistance of the material under the conditions of gradually reducing the friction intensity or sparse abrasive density can be simulated, thereby evaluating its adaptability in a light-load, low-wear environment. During the test process of gradually decreasing abrasive, the amount of abrasive released gradually decreases as the volume of the discharge chamber 108 decreases. This design can more accurately examine the wear resistance attenuation characteristics of the material under different abrasive densities. At the same time, the test method of gradually reducing the amount of abrasive can reduce the force strength on the surface of the material, and help to more carefully analyze the durability and performance change of the material under long-term slight wear. This test mode of cyclic increasing and decreasing abrasive provides a more comprehensive dynamic evaluation system for the wear resistance of building materials. Through multiple rounds of testing, comprehensive performance data on materials under different friction conditions, abrasive densities and pressures can be obtained. These data can not only be used for performance optimization in material research and development, but also provide accurate selection basis for engineering applications of materials. In addition, the horizontal shaking detection platform 102 that allows the shaking component to be horizontal can make the abrasive evenly contact the surface of the test piece and generate friction. Through this shaking method, the variable friction environment that building materials may encounter during actual use can be effectively simulated. This design can accurately control the distribution and friction intensity of the abrasive, so that the friction conditions to which the material is subjected during the test are closer to the actual use conditions, thereby improving the reliability and authenticity of the wear resistance test. After the pressure plate 109 moves downward to the preset position (contacting the abrasive and applying a preset pressure to the abrasive), the detection platform 102 is shaken horizontally. By using this precise shaking timing, it is possible to avoid the test error caused by uneven distribution of abrasive or local pressure differences due to the abrasive being separated from the test piece due to shaking before the abrasive is subjected to the pressure of the pressure plate 109. Compared with the wear resistance test equipment in the prior art, this application significantly improves the authenticity and comprehensiveness of the wear resistance test by introducing a test design that dynamically adjusts the abrasive release amount and variable friction conditions.

[0065] As a further solution of the present invention, the adjusting component includes a connecting port 200 opened in the discharge chamber 108, the connecting port 200 is connected to the discharge shaft 106, an adjusting shaft 201 is rotatably connected in the discharge shaft 106, a lead screw a202 is connected to the adjusting shaft 201, the lead screw a202 is a reciprocating lead screw, a limit plate 203 is connected to the lead screw a202, two sliding rings 204 slidably connected to the discharge shaft 106 are threadedly connected to the lead screw a202, a connecting rod 205 is rotatably connected to the sliding ring 204, a connecting plate 206 is provided in the discharge chamber 108, baffles 207 are slidably connected on both sides of the connecting plate 206, a spring a208 is connected between the baffle 207 and the connecting plate 206, and the other end of the connecting rod 205 is rotatably connected to the connecting plate 206;

[0066] By providing the connecting plate 206 and the baffle 207, the connecting plate 206 and the baffle 207 form an isolation zone to block the abrasive. The closer the connecting plate 206 and the baffle 207 are to the discharge shaft 106, the larger the volume of the discharge chamber 108 for accommodating the abrasive. The farther the connecting plate 206 and the baffle 207 are from the discharge shaft 106, the smaller the volume of the discharge chamber 108 for accommodating the abrasive. When the container 104 moves, the discharge shaft 106 rotates to drive the adjustment shaft 201 therein to rotate. When the adjustment shaft 201 rotates with the discharge shaft 106, the positions of the connecting plate 206 and the baffle 207 remain unchanged. When the discharge shaft 106 does not rotate, the adjusting shaft 201 can be rotated alone to move the position of the sliding ring 204 through the force of the thread of the lead screw a202. The sliding rings 204 on the two lead screws a202 can move away from or towards each other. The position of the connecting plate 206 can be adjusted by using the connecting rod 205 to allow the connecting plate 206 to move closer to or away from the discharge shaft 106. At this time, the baffle 207 slides on the side wall of the discharge plate 107 and is tightly attached to the discharge plate 107 through the potential energy of the spring a208, thereby achieving the purpose of adjusting the volume of the discharge chamber 108 for accommodating the abrasive, thereby achieving the effect of being able to flexibly adjust the volume of the discharge chamber 108 to control the amount of abrasive released. In addition, the lead screw a202 is designed as a reciprocating lead screw. When the lead screw a202 rotates a preset number of times to move the connecting plate 206 so that the volume of the discharge chamber 108 containing the abrasive reaches the maximum or minimum amount, the lead screw a202 can automatically change the moving direction of the sliding ring 204 when it rotates again through its reciprocating design characteristics. This design can realize the dynamic adjustment of the volume of the discharge chamber 108, which supports both gradually increasing the amount of abrasive to test the wear resistance of the material under high abrasive density conditions, and gradually reducing the amount of abrasive to simulate the wear environment under light load conditions.

[0067] As a further solution of the present invention, a connecting frame 300 is connected to the top of the detection box 101, and the container 104 is slidably connected to the connecting frame 300. A rack a301 is connected to the bottom of the connecting frame 300. Both ends of the discharge shaft 106 extend to the outside of the container 104 and are connected to a gear a302 adapted to the rack a301.

[0068] The rack a301 is connected to a rack b303, and both ends of the adjustment shaft 201 extend to the outside of the discharge shaft 106 and are connected to a gear b304 meshing with the rack b303;

[0069] By setting the connecting frame 300, the container 104 can be slidably connected to the connecting frame 300, so as to achieve stable movement in the detection box 101. At the same time, a rack a301 is set at the bottom of the connecting frame 300, and the two ends of the discharge shaft 106 extend to the outside of the container 104 and are connected to the gear a302 adapted to the rack a301. When the rack a301 and the gear a302 are meshed with each other, the container 104 drives the discharge shaft 106 to rotate synchronously through the gear transmission mechanism during the movement, so as to achieve uniform release of the abrasive. This design can effectively ensure the moving stability of the container 104 and the synchronous rotation of the discharge shaft 106, so that the abrasive is evenly distributed on the detection platform 102, avoiding the uneven distribution of the abrasive caused by the uneven movement of the container 104 or the asynchronous rotation of the discharge shaft 106. In addition, by setting the rack b303, the length of the rack b303 is shorter than the rack a301. When the container 104 moves to the preset position, the gear a302 on the discharge shaft 106 is disengaged from the rack a301, and the gear b304 can mesh with the rack b303. As the container 104 continues to move, the adjustment shaft 201 can rotate independently. This design can accurately control the volume change of the discharge chamber 108 when the container 104 moves to the preset position, and realize flexible adjustment of the abrasive amount through the independent rotation of the adjustment shaft 201. This structure can not only meet the needs of gradually increasing or decreasing the abrasive amount during multiple rounds of testing, but also improve the automation and ease of operation of the equipment, making the wear test more diverse and adaptable, and suitable for the wear performance evaluation of different materials and test conditions.

[0070] As a further solution of the present invention, a ratchet mechanism a305 is provided between the gear a302 and the discharge shaft 106, and a ratchet mechanism b306 is provided between the gear b304 and the adjustment shaft 201;

[0071] By setting the ratchet mechanism a305 and the ratchet mechanism b306, the rotation direction of the discharge shaft 106 and the adjustment shaft 201 can be unidirectionally controlled, so that when the container 104 moves back to the origin, the abrasive will not be released into the detection platform 102, causing unnecessary release and waste of the abrasive. At the same time, the ratchet mechanism b306 can prevent the adjustment shaft 201 from rotating in the reverse direction, thereby ensuring that the volume of the discharge chamber 108 after adjustment remains stable, avoiding volume changes caused by reverse rotation, and affecting the test accuracy and reliability of the results.

[0072] As a further solution of the present invention, an elastic telescopic rod 307 is connected to the container 104, and one end of the elastic telescopic rod 307 is connected to a limiting boss 308 that abuts against the discharge shaft 106;

[0073] By setting up the elastic telescopic rod 307, the elastic telescopic rod 307 can allow the limiting boss 308 to touch the discharge shaft 106, so that after the gear a302 and the rack a301 are disengaged and the gear b304 and the rack b303 are engaged with the adjustment shaft 201 to rotate, it will not affect the angle of the discharge shaft 106, avoiding the problem of adjustment failure.

[0074] As a further solution of the present invention, the moving part includes a lead screw b400 rotatably connected to the detection bracket 100, a motor 401 is provided at the bottom of the lead screw b400, a frame 402 is connected to the top of the pressure plate 109, and the frame 402 is threadedly connected to the lead screw b400;

[0075] The moving part also includes a lead screw c403 rotatably connected to the connecting frame 300, the container 104 is threadedly connected to the lead screw c403, the lead screw b400 is connected to a gear c404, a connecting shaft 405 is rotatably connected to the connecting frame 300, the connecting shaft 405 is connected to a gear d406 meshing with the gear c404, and a chain transmission mechanism 407 is provided between the connecting shaft 405 and the lead screw c403;

[0076] By setting up the motor 401, the screw b400 can be driven to rotate, thereby driving the frame 402 threadedly connected thereto to move up and down, and realizing precise control of the position of the pressure plate 109. At the same time, the connecting shaft 405 is driven to rotate through the gear c404 and the gear d406, and the power is transmitted to the screw c403 through the chain transmission mechanism 407, thereby pushing the container 104 threadedly connected thereto to slide along the connecting frame 300. Such a design can realize the synchronous or independent adjustment of the position of the pressure plate 109 and the container 104, ensure the coordination of the abrasive release and pressure loading process, and improve the flexibility and applicability of the test equipment.

[0077] As a further solution of the present invention, the shaking component includes a slider 500 slidably connected to both sides of the detection platform 102, a threaded tube 501 is connected to the slider 500, a spring b502 is connected between the slider 500 and the detection platform 102, a sliding frame 503 is respectively connected to both sides of the detection box 101, a spring c504 is connected between the sliding frame 503 and the detection box 101, a lead screw d505 threadedly connected to the sliding frame 503 is rotatably connected, the lead screw d505 is a reciprocating lead screw, a top contact rod 506 is connected to the bottom of the frame 402, which vertically corresponds to the position of the sliding frame 503, a rotating shaft 507 is provided at the bottom of the lead screw b400, the rotating shaft 507 is connected to the driving shaft of the motor 401, a gear e508 is connected to the rotating shaft 507, a gear f509 adapted to the gear e508 is connected to the lead screw d505, and a preset distance is provided between the gear e508 and the gear f509;

[0078] By setting the rotating shaft 507, when the motor 401 is working, the rotating shaft 507 can be rotated, and the rotation of the rotating shaft 507 can drive the gear e508 thereon to rotate. In the initial state, the height of the lead screw d505 and the gear f509 thereon is higher than the gear e508, and they are not meshed with the gear e508. When the rotating shaft 507 rotates to rotate the lead screw b400, the frame 402 and the pressure plate 109 will continue to move downward until the pressure plate 109 contacts the abrasive and the detection part, and the top contact rod 506 on the frame 402 can press the position of the sliding frame 503 to allow the sliding frame 503 and the lead screw d505 to move downward, so that the gear f509 is meshed with the gear e508, and when the lead screw d505 moves downward, the threaded tube 501 can move downward together. When the motor 401 continues to rotate in the same direction, the gear e508 and the gear f509 drive the lead screw d505 to rotate, and the reciprocating design of the lead screw d505 causes the threaded tube 501 to repeatedly move along the thread direction of the lead screw d505, thereby driving the slider 500 and the detection platform 102 to perform lateral reciprocating motion. This achieves the coordinated action of the loading of the pressure plate 109 and the shaking of the detection platform 102, and avoids the problem of the loss of abrasive on the detection piece due to the shaking of the detection platform 102 when the pressure plate 109 is not loaded in place.

[0079] As a further solution of the present invention, the top of the rotating shaft 507 is connected to a connecting platform 600, the bottom of the lead screw b400 is connected to a connecting ring 601 sleeved on the outside of the connecting platform 600, the outer wall of the connecting platform 600 is slidably connected to a plurality of push rods 602, a spring d603 is connected between the push rods 602 and the connecting platform 600, the inner wall of the connecting ring 601 is provided with a plurality of top grooves 604, the top grooves 604 are semi-spherical grooves, and one end of the push rod 602 adapted to the top groove 604 is semi-spherical;

[0080] By setting the spring d603, the elastic potential energy of the spring d603 is greater than that of the spring b502 and the spring rod c. The spring d603 can give the push rod 602 a force to touch the top groove 604, so that a certain friction force is formed between the push rod 602 and the top groove 604, and the friction force can be used to realize the rotation of the transmission screw b400 when the rotating shaft 507 rotates. When the screw b400 rotates to allow the pressure plate 109 to move downward, the force of the spring b502 and the spring c504 can be overcome, until the pressure plate 109 contacts the abrasive and the detection part, and the movement of the pressure plate 109 encounters resistance. At this time, the rotating shaft 507 continues to rotate under the drive of the motor 401. At this time, the rotation of the rotating shaft 507 and the connecting platform 600 can overcome the force of the spring d603, so that the push rod 602 and the top groove 604 are separated. The rotating shaft 507 can idle at the bottom of the screw b400. In this case, the shaft 507 can idle at the bottom of the screw b400 and drive the shaking component to work, so that the detection platform 102 can move back and forth horizontally to complete the wear test. This design not only realizes the loading function of the pressure plate 109, but also ensures that the shaft 507 can be flexibly switched to the shaking mode through the force-controlled separation mechanism of the spring d603, effectively avoiding system action conflicts and improving the reliability of the equipment and the accuracy of the test process.

[0081] As a further solution of the present invention, the bottom of the pressure plate 109 is slidably connected to the limit frame 700, and a spring e701 is connected between the limit frame 700 and the pressure plate 109;

[0082] By setting the pressure plate 109, when the operator places the building materials to be tested in the testing platform 102, the position of the building materials can be appropriately adjusted to correspond to the position of the pressure plate 109. When the pressure plate 109 is subsequently moved downward to the position of the abrasive and the building materials, the limit frame 700 can effectively frame the released abrasive, limit the abrasive within the testing area, avoid the diffusion of the abrasive, ensure the full contact between the abrasive and the building materials, and further improve the accuracy and uniformity of the wear test. This design not only improves the utilization efficiency of the abrasive, but also effectively avoids the overflow or waste of the abrasive, provides a more stable environment for the wear test, and ensures the reliability and consistency of the test results.

[0083] As a further solution of the present invention, the fixing part 103 includes a hydraulic lever 702 connected to the detection platform 102, and a positioning plate 703 is connected to the telescopic shaft of the hydraulic lever 702;

[0084] By setting the hydraulic lever 702, the positioning and fixing of the building materials on the testing platform 102 can be accurately controlled. The telescopic function of the hydraulic lever 702 can adjust the position of the positioning plate 703 as needed, thereby achieving rapid and stable fixing of the building materials. Under the action of the hydraulic lever 702, the positioning plate 703 can achieve accurate positioning of the building materials in a short time, ensuring that the building materials will not move or deviate from the predetermined position due to external forces during the test. In this way, test errors can be avoided and the accuracy and reliability of the test results can be improved.
