In actual applications, thermal insulation materials are often subjected to 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 above existing problems, the present invention is proposed.
[0006] The purpose of the present invention is to solve the problem that the pressure bearing detection function of the thermal insulation material is relatively single in the prior art.
[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0008] On the one hand, the present invention provides a pressure-bearing and heat-insulating detection device for heat-insulating materials, which includes a detection platform and a detection mechanism. The detection mechanism is arranged above the detection platform. The detection mechanism includes a wear-resistant detection module and a pressure-resistant detection module. The wear-resistant detection module includes a mold core and a hammering mechanism. The mold core is adjusted up and down and is arranged at the upper end of the detection platform.

[0010] Furthermore, the mold core is a hollow structure, and a first inner groove is provided on the outer side of the mold core toward the hammering mechanism, and the first inner groove is not connected to the interior of the mold core. The first temperature sensor is arranged in the first inner groove, and a second inner groove is provided on the outer side of the lower end of the mold core, and the second inner groove is not connected to the interior of the mold core. A second temperature sensor is provided in the second inner groove, and a quartz heating tube and a semiconductor refrigeration component are respectively provided inside the mold core. A control box and a display are provided on the detection table, and a single-chip microcomputer is provided in the control box. The first temperature sensor and the second temperature sensor are electrically connected to the display through the single-chip microcomputer respectively. The first temperature sensor and the second temperature sensor convert the detected temperature into an electrical signal and transmit it to the single-chip microcomputer. After the single-chip microcomputer processes the signal, the temperature data is sent to the display for display, which is convenient for the staff to observe, wherein the quartz heating tube and the semiconductor refrigeration component are respectively electrically connected to the external power supply.
[0011] Furthermore, the pressure resistance detection module is located at the center of the detection platform, and the wear resistance detection module is provided with two groups and is symmetrically arranged on both sides of the pressure resistance detection module. The upper end of the mold core is assembled and connected to the upper end of the detection platform through a first cylinder. The upper end of the detection 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, and the rotating shaft is rotatably arranged at the upper end of the detection platform. The rotating shaft is linked to the reciprocating mechanism. By driving the first cylinder, the first cylinder can be driven to extend, and the mold core can be pressurized or lifted. By driving the first motor, the reciprocating mechanism is driven, and the first cylinder is driven to perform reciprocating swinging motion, so as to achieve friction testing of the thermal insulation material located at the lower end of the mold core.
[0012] Furthermore, the reciprocating mechanism is provided with two groups and is symmetrically arranged. The reciprocating mechanism includes a connecting frame, a first turntable and a fixed shaft. The connecting frame is linked and arranged at the upper end of the rotating shaft. The first motor is a bidirectional motor. The output end of the first motor is linked and arranged with the first turntable. A ring is provided at the edge of the first turntable. The fixed shaft is arranged on the connecting frame. The ring is slidably sleeved on the fixed shaft. By driving the bidirectional motor, the first turntable is driven to rotate, and the ring moves in a circular motion. The ring is sleeved up and down on the fixed shaft. When the ring is located on both sides of the first turntable, the connecting frame is in a left-right swinging state, driving the first cylinder and the mold core to swing left-right.
[0013] Furthermore, the detection table is provided with a mounting frame, the hammering mechanism is arranged on the mounting frame, the hammering mechanism includes a disc frame, a limiting frame and a hammer head, the disc frame is arranged on the mounting frame, a second turntable is rotatably provided on one side of the inner part of the disc frame, a second motor is provided on the outer side of the disc frame, the second turntable is driven to rotate by the second motor, a rotating block is provided at the edge of the second turntable, a push shaft is hingedly provided on the rotating block through a connecting strip, the end face of the push shaft is perpendicular to the hammer head, and the limiting frame is connected to the end of the disc frame facing the mold core body. The hammer head is slidingly arranged in the limit frame, and the second turntable is driven to rotate by driving the second motor, and the rotating block at the edge of the second turntable performs a circular motion accordingly. Since the two ends of the connecting strip are respectively connected to the rotating block and the end face of the push shaft, when the rotating block is located away from the hammer head, the rotating block pulls the connecting strip and the push shaft to move away from the mold core body, and vice versa, the hammer head is pushed toward the mold core body, thereby realizing reciprocating hammering of the thermal insulation material on the outside of the mold core body. During the hammering process, the lower end of the mold core body is always in the limit groove, and the mold core body will not be displaced, thereby ensuring the stability of the test.
[0014] Furthermore, a slider is provided at the lower end of the mounting frame, and a slide groove is provided on the testing platform to be slidably adapted to the slider. A screw rod is provided to rotate in the slide groove, and one end of the screw rod extends to the outside of the testing platform. A threaded groove is provided at the center of the slider and is threadedly sleeved with the screw rod. By rotating the screw rod at the outer end, the slider is driven to move back and forth in the slide groove, thereby achieving the effect of fine-tuning the distance between the disc rack and the thermal insulation material, so that during the hammering test, it can be adjusted at any time according to the thickness of the thermal insulation material.
[0015] Furthermore, a sealing cover is detachably provided on the front of the fixing frame, a U-shaped frame is provided at the center position inside the fixing frame, and a mounting groove for slidingly installing a thermal insulation material is provided at the center position of the U-shaped frame. The sealing cover is provided on the inner side and is provided with a cover groove adapted to the end face of the U-shaped frame and the thermal insulation material.

Air bags are laid in the first assembly slot and the second assembly slot, and an air pump is provided above the fixing frame. The two air bags are inflated and deflated by the air pump. The first assembly slot and the second assembly slot have the same structure and a storage slot is provided on the upper part thereof. An insertion strip is provided in the storage slot through a spring. After the insulation board and the sealing cover are installed, the air pump is started to inflate the air bag so that the air bag fits tightly with the insulation board to avoid gas communication in the space on both 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 is in an extended state, pushing the insertion strip to squeeze the deflated air bag and store it in the first assembly slot or the second assembly slot to avoid affecting the installation of the insulation board and the mounting slot. When the air bag is inflated, the pressure of the bulging air bag pushes the insertion strip to move upward and retract into the storage slot.
[0017] Furthermore, a pressure piece is provided on the side of the fixing frame away from the vacuum tube, and the pressure piece includes a second cylinder and a push plate. One end of the second cylinder is provided on the inner wall of the fixing frame, and the output end of the second cylinder is assembled and connected to the push plate.

By applying different pressures, it is observed whether the insulation board is deformed or damaged.
[0018] The beneficial effects of the present invention are:
[0019] By integrating a wear-resistant detection module and a pressure-resistant detection module, the present invention can simultaneously simulate the complex working conditions such as pressure, friction, and temperature changes that insulation materials are subjected to in actual applications. The wear-resistant detection module tests the attenuation changes of the material's thermal insulation performance under dynamic friction and impact through the synergistic effect of the reciprocating swing of the mold core and the hammering mechanism. The pressure-resistant detection module, combined with a vacuum pump and a pressure-applying member, can test the deformation characteristics of the rigid insulation board under negative pressure and mechanical pressure. Compared with traditional single-performance testing devices, the present invention can more realistically reflect the comprehensive performance of the material under complex environments, effectively solving the problem of large deviations between test results and actual applications. In addition, the device supports simultaneous testing of different types of insulation materials, such as rigid and flexible insulation materials. The middle and lower sections of the mold core can simultaneously fix two materials for friction testing and pressure testing, respectively. The rigid insulation board in the vacuum chamber can be independently tested for pressure resistance and airtightness. This design not only avoids the tedious operation of frequently changing test tooling in traditional equipment, but also greatly improves testing efficiency, making it particularly suitable for batch quality inspection scenarios.

By applying different pressures, it is observed whether the insulation board is deformed or damaged.
[0045] Working principle: Since there are many kinds of thermal insulation materials, the detection methods for different materials in different scenarios are different. Hot insulation or cold insulation can be selected according to the needs. The mold core 2 can be heated or cooled to the set temperature, and the thermal insulation material is cut and wrapped and fixed at the bottom of the mold core 2. The first cylinder 811 is extended to drive the mold core 2 to move downward, so that the thermal insulation material is located between the limit groove 3 and the mold core 2. The first cylinder 811 is continued to extend, and the mold core 2 can apply pressure to the thermal insulation material. The temperature change of the second temperature sensor 713 at the bottom of the mold core 2 under different pressures is recorded. In addition, the first motor 812 is driven to drive the first cylinder 811 and the mold core 2 to perform a small range of high frequency The left and right swings generate friction between the insulation material and the limit groove 3 and the mold core 2 during the swinging process. The test is used to simulate the insulation material wrapped around the outside of the heavy object. Under high-intensity pressure and slight shaking, whether the insulation material will be damaged, and if it is damaged, whether the degree of damage affects the insulation effect. The judgment is made by observing the temperature change of the second temperature sensor 713 before and after the pressure is applied 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 insulation material can be impact tested by driving the hammering mechanism. In addition, the hammering test can also be carried out synchronously with the rotation extrusion test of another insulation material set at the lower end of the mold core 2. The reciprocating rotation of the mold core 2 It can increase the friction effect and increase the friction area of the insulation material in the middle section, so that the experimental effect is better. The experiment is used to simulate the situation when the insulation material is frequently stepped on or frequently rubbed against other structures to see whether it is easy to be damaged and cause insulation failure. After the test is completed, the temperature difference between the front and back of the first temperature sensor 4 can be observed. Finally, for some hard insulation boards or hollow insulation boards, they can be placed in the cavity 513 of the fixed frame 511, and the sealing cover 911 is covered so that the insulation board can seal the cavity 513 from the middle. The external vacuum pump 514 is driven to extract the gas on one side of the cavity 513 through the vacuum tube 512. By applying different vacuum pressures, the temperature is observed. Whether the insulation board is deformed or damaged can be determined by applying pressure to the insulation board through a pressure piece located on one side of the cavity 513. By applying different pressures, it is observed whether the insulation board is deformed or damaged. The insulation material is inspected in different ways by the above-mentioned wear-resistant detection module and pressure-resistant detection module. The inspection content is more comprehensive, and simultaneous inspection operations can be performed on different detection modules. For example, the inspection of two insulation materials arranged in the middle and lower sections of the mold core 2 can not only improve the inspection efficiency, but also increase the friction range of the insulation material in the wear-resistant test, making the inspection effect more significant. In addition, the tests of the wear-resistant detection module and the pressure-resistant detection module can be carried out simultaneously, which can improve the inspection efficiency of different insulation materials.
