Description

Technical Field

[0001] This invention relates to the field of thermal insulation material testing technology, and in particular to a pressure-bearing thermal insulation testing device for thermal insulation materials. Background Technology

[0002] Thermal insulation materials are widely used in construction, industrial equipment and other fields. Their thermal insulation performance, wear resistance and compressive strength directly affect their performance and lifespan.

[0003] For example, CN119715130A describes a pressure-bearing and thermal insulation testing device for thermal insulation materials. This device includes a workbench with a first pressure-bearing testing mechanism for fixing the thermal insulation material. The first pressure-bearing testing mechanism includes a first clamping seat fixed to the workbench and fitted over the outside of the thermal insulation material. An inner tube for inserting into the inner side of the thermal insulation material passes through the first clamping seat. The inner tube has three non-communicating areas. A second pressure-bearing testing mechanism for testing the middle portion of the thermal insulation material is also provided on the workbench. The purpose of this invention is to provide a pressure-bearing and thermal insulation testing device for thermal insulation materials. This device can test the pressure-bearing performance of the thermal insulation material under constant pressure and simultaneously perform thermal insulation testing. The two tests are performed concurrently and in coordination, improving the quality of the thermal insulation material while further increasing the testing efficiency.

[0004] However, in the existing technology, the common testing methods for thermal insulation materials are mostly single performance tests, such as testing thermal insulation through a constant temperature chamber or testing compressive strength through a pressure machine. In practical applications, thermal insulation materials often bear the combined effects of pressure, friction and temperature changes at the same time. Existing testing devices are difficult to simulate complex working conditions, resulting in deviations between test results and actual performance. Summary of the Invention

[0005] In view of the aforementioned existing problems, the present invention is proposed.

[0006] The purpose of this invention is to solve the problem that the existing technology has a relatively simple function for testing the pressure resistance of thermal insulation materials.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] On one hand, the present invention provides a pressure-bearing insulation testing device for insulation materials, which includes a testing platform and a testing mechanism. The testing mechanism is disposed above the testing platform and includes an abrasion resistance testing module and a pressure resistance testing module. The abrasion resistance testing module includes a mold core and a hammering mechanism. The mold core is vertically adjustable and disposed on the upper part of the testing platform. The testing platform is provided with a limiting groove adapted to the lower end of the mold core. The middle and lower sections of the mold core are respectively used for winding different insulation materials. The hammering mechanism is disposed on the testing platform and is used to apply pressure to the insulation material located in the middle section for testing. A first temperature sensor is provided on the outer wall of the mold core. The pressure resistance testing module includes a fixing frame and a vacuum tube. The fixing frame has multiple cavities for placing rigid insulation materials. The cavity on one side of the rigid insulation material is connected to an external vacuum pump through the vacuum tube.

[0009] Furthermore, the lower end of the mold core is spherical, and the upper and lower ends of the mold core are respectively provided with waist grooves. The upper and lower ends of the insulation material located in the middle section of the mold core can be tied and fixed to the upper and lower waist grooves respectively by the first cable tie. The upper end of the insulation material located at the lower end of the mold core can be tied and fixed to one of the waist grooves at the lower end by the second cable tie.

[0010] Furthermore, the mold core is a hollow structure. A first inner groove is formed on the outer side of the mold core facing the hammering mechanism. The first inner groove is not connected to the interior of the mold core. The first temperature sensor is located in the first inner groove. A second inner groove is formed on the outer side of the lower end of the mold core. The second inner groove is not connected to the interior of the mold core. A second temperature sensor is located in the second inner groove. A quartz heating tube and a semiconductor cooling element are respectively provided inside the mold core. A control box and a display are provided on the detection platform. A microcontroller is provided in the control box. The first and second temperature sensors are electrically connected to the display through the microcontroller. The first and second temperature sensors convert the detected temperature into an electrical signal and transmit it to the microcontroller. After processing the signal, the microcontroller sends the temperature data to the display for observation by the staff. The quartz heating tube and the semiconductor cooling element are electrically connected to an external power supply.

[0011] Furthermore, the pressure resistance testing module is located at the center of the testing platform, and the wear resistance testing module is provided in two sets and symmetrically arranged on both sides of the pressure resistance testing module. The upper end of the mold core is assembled and connected to the upper end of the testing platform through a first cylinder. The upper end of the testing platform is provided with a first motor, and the output end of the first motor is linked to a reciprocating mechanism. The output end of the first cylinder is linked to a rotating shaft, which is rotatably mounted on the upper end of the testing platform. The rotating shaft is linked with the reciprocating mechanism. By driving the first cylinder, the first cylinder can be driven to extend, which can apply pressure to the mold core or lift it. By driving the first motor, the reciprocating mechanism is driven, which drives the first cylinder to perform a reciprocating oscillating motion, thereby achieving a friction test on the insulation material located at the lower end of the mold core.

[0012] Furthermore, the reciprocating mechanism is provided in two sets and symmetrically arranged. The reciprocating mechanism includes a connecting frame, a first turntable and a fixed shaft. The connecting frame is linked to the upper end of the turntable. The first motor is a bidirectional motor. The output end of the first motor is linked to the first turntable. A collar is provided at the edge of the first turntable. The fixed shaft is set on the connecting frame. The collar is slidably sleeved on the fixed shaft. By driving the bidirectional motor, the first turntable is driven to rotate. The collar moves in a ring. The collar is sleeved on the fixed shaft. When the collar is located on both sides of the first turntable, the connecting frame swings left and right, causing the first cylinder and the mold core to swing left and right.

[0013] Furthermore, the testing platform is equipped with a mounting frame, and the hammering mechanism is mounted on the mounting frame. The hammering mechanism includes a disc frame, a limiting frame, and a hammer head. The disc frame is mounted on the mounting frame, and a second turntable is rotatably mounted on one side inside the disc frame. A second motor is mounted on the outside of the disc frame, and the second turntable is driven to rotate by the second motor. A rotating block is provided at the edge of the second turntable, and a push shaft is hinged to the rotating block via a connecting strip. The end face of the push shaft is perpendicular to the hammer head. The limiting frame is connected to the end of the disc frame facing the mold core. The hammer head is slidably mounted within the limiting frame. Driven by the second motor, the second turntable rotates, and the rotating block at the edge of the second turntable moves in a circular motion. Since the two ends of the connecting strip are connected to the rotating block and the end face of the push shaft respectively, when the rotating block is located away from the hammer head, the rotating block pulls the connecting strip and the push shaft away from the mold core. Conversely, it pushes the hammer head towards the mold core, thereby reciprocatingly hammering the insulation material on the outside of the mold core. During the hammering process, the lower end of the mold core is always within the limiting groove, and the mold core will not be displaced, ensuring the stability of the test.

[0014] Furthermore, the mounting bracket has a slider at its lower end, and the testing platform has a sliding groove that is adapted to slide the slider. A lead screw is rotatably mounted in the sliding groove, with one end of the lead screw extending to the outside of the testing platform. A threaded groove is opened at the center of the slider and threadedly fitted with the lead screw. By rotating the outer end of the lead screw, the slider is driven to move back and forth in the sliding groove, achieving the effect of fine adjustment of the distance between the plate and the insulation material. This allows for adjustment at any time according to the thickness of the insulation material during the hammer test.

[0015] Furthermore, the fixing frame has a detachable sealing cover on its front side, and a U-shaped frame is provided at the center of the fixing frame. The U-shaped frame has an installation groove for sliding the insulation material at its center. The sealing cover has a cover groove on its inner side that is adapted to the end face of the U-shaped frame and the insulation material. The vacuum pump is installed on the testing platform, and the end of the vacuum tube away from the vacuum pump is connected to the fixing frame. When installing the insulation material, the sealing cover is opened, and the insulation board of the cut size is slid into the installation groove on the U-shaped frame for sealing and locking. Finally, the sealing cover is slid into the opening end of the fixing frame to seal.

[0016] Furthermore, the U-shaped frame is connected to a first assembly slot on one side of the mounting slot, and a second assembly slot is provided at the cover slot. Both the first and second assembly slots are filled with airbags. An air pump is provided above the fixing frame. Both airbags are inflated and deflated by the air pump. The first and second assembly slots have the same structure and have a storage slot at the top inside. An insert is provided in the storage slot through a spring. After the insulation board and sealing cover are installed, the air pump is started to inflate the airbags, so that the airbags are tightly fitted to the insulation board, preventing the air from communicating between the two sides of the insulation board. This makes the air pressure test on both sides of the insulation board more accurate. In the initial state, the spring is in an extended state, pushing the insert to squeeze the deflated airbag into the first or second assembly slot to avoid affecting the installation of the insulation board and the mounting slot. When the airbag is inflated, the pressure of the inflated airbag pushes the insert upward and retracts into the storage slot.

[0017] Furthermore, a pressure-applying component is provided inside the fixed frame on the side away from the vacuum tube. The pressure-applying component includes a second cylinder and a push plate. One end of the second cylinder is located on the inner wall of the fixed frame, and the output end of the second cylinder is assembled and connected to the push plate. The push plate faces the center of the insulation board. By activating the second cylinder to extend it, the push plate pushes the insulation board. By applying different pressures, it is observed whether the insulation board deforms or breaks.

[0018] The beneficial effects of this invention are:

[0019] This invention integrates a wear resistance testing module and a compressive strength testing module, enabling simultaneous simulation of complex working conditions such as pressure, friction, and temperature changes experienced by thermal insulation materials in practical applications. The wear resistance testing module, through the synergistic action of the reciprocating oscillation of the mold core and the hammering mechanism, tests the decay of the material's thermal insulation performance under dynamic friction and impact. The compressive strength testing module, combined with a vacuum pump and pressure application components, tests the deformation characteristics of rigid insulation boards under negative pressure and mechanical pressure. Compared to traditional single-performance testing devices, this invention more realistically reflects the comprehensive performance of materials in complex environments, effectively solving the problem of large discrepancies between test results and actual applications. Furthermore, this device supports simultaneous testing of different types of thermal insulation materials, such as rigid and flexible materials. The middle and lower sections of the mold core can simultaneously fix two materials for friction and pressure testing, respectively. The rigid insulation board within the vacuum chamber can be independently tested for compressive strength and airtightness. This design not only avoids the cumbersome operation of frequently changing testing fixtures in traditional equipment but also significantly improves testing efficiency, making it particularly suitable for batch quality inspection scenarios.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, as used herein, "an embodiment" or "embodiment" refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0035] Please see Figures 1-9 This invention provides a technical solution: a pressure-bearing insulation testing device for insulation materials, comprising a testing platform 1 and a testing mechanism. The testing mechanism is positioned above the testing platform 1 and includes an abrasion resistance testing module and a pressure resistance testing module. The abrasion resistance testing module includes a mold core 2 and a hammering mechanism. The mold core 2 is vertically adjustable and positioned on the upper end of the testing platform 1. The testing platform 1 is provided with a limiting groove 3 adapted to the lower end of the mold core 2. The middle and lower sections of the mold core 2 are respectively used for winding different insulation materials. The hammering mechanism is positioned on the testing platform 1 and is used to apply pressure to the insulation material located in the middle section for testing. A first temperature sensor 4 is provided on the outer wall of the mold core 2. The pressure resistance testing module includes a fixing frame 511 and a vacuum tube 512. The fixing frame 511 has multiple cavities 513 for placing rigid insulation materials. The cavity 513 on one side of the rigid insulation material is connected to an external vacuum pump 514 through the vacuum tube 512.

[0036] like Figures 1-9 As shown, the lower end of the mold core 2 is spherical, and the upper and lower ends of the mold core 2 are respectively provided with waist grooves 6. The upper and lower ends of the insulation material located in the middle section of the mold core 2 can be tied and fixed to the upper and lower waist grooves 6 respectively by the first cable tie. The upper end of the insulation material located at the lower end of the mold core 2 can be tied and fixed to one of the lower waist grooves 6 by the second cable tie.

[0037] like Figures 1-9As shown, the mold core 2 has a hollow structure. A first inner groove 711 is formed on the outer side of the mold core 2 facing the hammering mechanism. The first inner groove 711 is not connected to the interior of the mold core 2. A first temperature sensor 4 is disposed within the first inner groove 711. A second inner groove 712 is formed on the lower outer side of the mold core 2. The second inner groove 712 is not connected to the interior of the mold core 2. A second temperature sensor 713 is disposed within the second inner groove 712. A quartz heating tube 714 and a semiconductor cooling element 715 are respectively disposed inside the mold core 2. The testing table 1 is equipped with... The control box 716 and the display 717 are equipped with a microcontroller. The first temperature sensor 4 and the second temperature sensor 713 are electrically connected to the display 717 through the microcontroller. The first temperature sensor 4 and the second temperature sensor 713 convert the detected temperature into an electrical signal and transmit it to the microcontroller. After processing the signal, the microcontroller sends the temperature data to the display 717 for display, which is convenient for the staff to observe. The quartz heating tube 714 and the semiconductor cooling element 715 are electrically connected to an external power supply.

[0038] like Figures 1-9 As shown, the pressure resistance testing module is located at the center of the testing platform 1. The wear resistance testing module has two sets and is symmetrically arranged on both sides of the pressure resistance testing module. The upper end of the mold core 2 is connected to the upper end of the testing platform 1 through the first cylinder 811. The upper end of the testing platform 1 is equipped with a first motor 812. The output end of the first motor 812 is linked to a reciprocating mechanism. The output end of the first cylinder 811 is linked to a rotating shaft 813. The rotating shaft 813 is rotatably mounted on the upper end of the testing platform 1. The rotating shaft 813 is linked with the reciprocating mechanism. By driving the first cylinder 811, the first cylinder 811 can be driven to extend, which can apply pressure to the mold core 2 or lift it. By driving the first motor 812, the reciprocating mechanism is driven, which drives the first cylinder 811 to perform a reciprocating swinging motion, so as to achieve friction testing on the insulation material located at the lower end of the mold core 2.

[0039] like Figures 1-9 As shown, the reciprocating mechanism has two sets arranged symmetrically. The reciprocating mechanism includes a connecting frame 821, a first turntable 822, and a fixed shaft 823. The connecting frame 821 is linked to the upper end of the rotating shaft 813. The first motor 812 is a bidirectional motor. The output end of the first motor 812 is linked to the first turntable 822. A collar 825 is provided at the edge of the first turntable 822. The fixed shaft 823 is set on the connecting frame 821. The collar 825 is slidably sleeved on the fixed shaft 823. By driving the first motor 812, the first turntable 822 is driven to rotate. The collar 825 moves in a ring. The collar 825 is sleeved on the fixed shaft 823. When the collar 825 is located on both sides of the first turntable 822, the connecting frame 821 swings left and right, causing the first cylinder 811 and the mold core 2 to swing left and right.

[0040] like Figures 1-9 As shown, the testing table 1 is equipped with a mounting frame 83, and the hammering mechanism is mounted on the mounting frame 83. The hammering mechanism includes a disc frame 841, a limiting frame 842, and a hammer head 843. The disc frame 841 is mounted on the mounting frame 83. A second turntable 844 is rotatably mounted on one side inside the disc frame 841, and a second motor 845 is mounted on the outside of the disc frame 841. The second turntable 844 is driven to rotate by the second motor 845. A rotating block 846 is provided at the edge of the second turntable 844. A push shaft 848 is hinged to the rotating block 846 through a connecting strip 847. The end face of the push shaft 848 is perpendicular to the hammer head 843. The limiting frame 842 is connected to the end of the disc frame 841 facing the mold core 2. The hammer head 843 slides. Set within the limiting frame 842, the second motor 845 drives the second turntable 844 to rotate, causing the rotating block 846 at the edge of the second turntable 844 to perform circular motion. Since the two ends of the connecting strip 847 are connected to the end faces of the rotating block 846 and the push shaft 848 respectively, when the rotating block 846 is located away from the hammer head 843, the rotating block 846 pulls the connecting strip 847 and the push shaft 848 to move away from the mold core 2, and vice versa, it pushes the hammer head 843 towards the mold core 2, thereby reciprocatingly hammering the insulation material on the outside of the mold core 2. During the hammering process, the lower end of the mold core 2 is always within the limiting groove 3, and the mold core 2 will not be displaced, ensuring the stability of the test.

[0041] like Figures 1-9 As shown, the mounting bracket 83 has a slider 851 at its lower end, and the testing table 1 has a sliding groove 852 that is adapted to slide the slider 851. A lead screw 853 is rotatably installed in the sliding groove 852. One end of the lead screw 853 extends to the outside of the testing table 1. A threaded groove is opened at the center of the slider 851 and is threadedly fitted with the lead screw 853. By rotating the outer end of the lead screw 853, the slider 851 is driven to move back and forth in the sliding groove 852, thereby achieving the effect of fine adjustment of the distance between the plate frame 841 and the insulation material. This allows for adjustment at any time according to the thickness of the insulation material during the hammer test.

[0042] like Figures 1-9 As shown, the front of the fixing frame 511 is detachably equipped with a sealing cover 911. A U-shaped frame 912 is provided at the center of the fixing frame 511. An installation groove 913 for sliding installation of insulation material is opened at the center of the U-shaped frame 912. The inner side of the sealing cover 911 is provided with a cover groove 914 that is adapted to the end face of the U-shaped frame 912 and the insulation material. The vacuum pump 514 is set on the testing table 1. The end of the vacuum tube 512 away from the vacuum pump 514 is connected to the fixing frame 511. When installing the insulation material, the sealing cover 911 is opened, and the insulation board of the cut size is slid into the installation groove 913 on the U-shaped frame 912 for sealing and locking. Finally, the sealing cover 911 is slid into the open end of the fixing frame 511 to seal.

[0043] like Figures 1-9 As shown, the U-shaped frame 912 is connected to the first assembly slot 921 on one side of the mounting slot 913, and the second assembly slot 922 is opened at the cover slot 914. Airbags 923 are laid in both the first and second assembly slots 921 and 922. An air pump 924 is installed above the fixing frame 511. Both airbags 923 are inflated and deflated by the air pump 924. The first assembly slot 921 and the second assembly slot 922 have the same structure, and a storage slot 925 is opened at the top inside. Inserts 927 are installed in the storage slot 925 via springs 926. The insulation board and the sealing cover 911 are both installed with... After installation, the air pump 924 is started to inflate the airbag 923, making the airbag 923 fit tightly against the insulation board and preventing gas communication between the two sides of the insulation board. This will make the air pressure test on both sides of the insulation board more accurate. In the initial state, the spring 926 is in the extended state, pushing the insert 927 to squeeze the deflated airbag 923 into the first assembly slot 921 or the second assembly slot 922 to avoid affecting the installation of the insulation board and the mounting slot 913. When the airbag 923 is inflated, the pressure of the inflated airbag 923 pushes the insert 927 upward and retracts it into the storage slot 925.

[0044] like Figures 1-9 As shown, a pressure-applying component is provided inside the fixed frame 511 on the side away from the vacuum tube 512. The pressure-applying component includes a second cylinder 101 and a push plate 102. One end of the second cylinder 101 is located on the inner wall of the fixed frame 511. The output end of the second cylinder 101 is assembled and connected to the push plate 102. The push plate 102 faces the center of the insulation board. By starting the second cylinder 101 to extend, the push plate 102 is driven to push the insulation board. By applying different pressures, it is observed whether the insulation board is deformed or damaged.

[0045] Working Principle: Since there are various types of insulation materials, different detection methods are used for different materials and in different scenarios. Depending on the needs, either thermal insulation or cold insulation can be selected. The mold core 2 can be heated or cooled to a set temperature. The insulation material is cut and wrapped around the bottom of the mold core 2. Extending the first cylinder 811 causes the mold core 2 to move downwards, positioning the insulation material between the limiting groove 3 and the mold core 2. Further extension of the first cylinder 811 allows the mold core 2 to apply pressure to the insulation material. The temperature change of the second temperature sensor 713 located at the bottom of the mold core 2 under different pressures is recorded. Additionally, driving the first motor 812 drives the first cylinder 811 and the mold core 2 to perform small-range, high-frequency movements. The left and right swinging motion generates friction between the insulation material and the limiting groove 3 and the mold core 2 during the swinging process. This test is used to simulate the insulation material wrapped around a heavy object. Under high-intensity pressure and slight shaking, it is tested whether the insulation material will break, and if so, whether the degree of breakage will affect the insulation effect. This is specifically judged by observing the temperature change of the second temperature sensor 713 before and after applying pressure to the insulation material. Another insulation material can be wrapped and fixed on the outer wall of the middle section of the mold core 2. The impact test of the insulation material can be performed by driving the hammering mechanism. In addition, the hammering test can also be carried out synchronously with the rotation and compression test of another insulation material set at the lower end of the mold core 2. The reciprocating rotation of the mold core 2 This increases friction, increasing the friction area of ​​the insulation material in the middle section, resulting in better experimental results. This experiment simulates situations where the insulation material is frequently stepped on or rubs against other structures, to determine if it is prone to damage leading to insulation failure. After the test, the temperature difference before and after the first temperature sensor 4 can be observed. Finally, for some rigid insulation boards or hollow insulation boards, they can be placed in the cavity 513 of the fixing frame 511, and the sealing cover 911 can be closed, so that the insulation board seals and separates the cavity 513 from the middle. The external vacuum pump 514 is driven to extract the gas from one side of the cavity 513 through the vacuum tube 512. By applying different vacuum pressures, the results are observed. To check whether the insulation board has deformed or broken, pressure can be applied to the insulation board by applying pressure to one side of the cavity 513. By applying different pressures, the insulation board can be observed to see if it deforms or breaks. The insulation material can be tested in different ways using the wear resistance test module and the compressive strength test module, making the test more comprehensive. Different test modules can be tested simultaneously. For example, testing the two insulation materials located in the middle and lower sections of the mold core 2 can not only improve the test efficiency but also increase the friction range of the insulation material in the wear resistance test, making the test results more significant. In addition, the wear resistance test module and the compressive strength test module can be tested simultaneously, which can improve the test efficiency for different insulation materials.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
