Description

Technical Field

[0001] This invention relates to the field of impact resistance testing technology, and more specifically, to a test device for impact resistance testing of thermal insulation wall panels based on intelligent sensors. Background Technology

[0002] Thermal insulation wall panels are building materials with thermal insulation properties, typically used for exterior walls, interior walls, or roofs. They effectively reduce heat transfer and decrease heating and cooling energy consumption. During the production and processing of thermal insulation wall panels, to ensure product quality stability, impact tests are conducted to simulate potential impact conditions encountered in real-world use scenarios. In this process, sensors precisely measure impact force, acceleration, displacement, and other physical quantities closely related to impact, converting these quantities into electrical or digital signals. This provides reliable and accurate data support for subsequent in-depth analysis and precise assessment of the impact resistance performance of the thermal insulation wall panels.

[0003] During impact resistance testing of thermal insulation wall panels, the impact resistance of different parts of the panel varies in actual application scenarios, requiring testing at multiple points on the panel surface. Existing equipment struggles to perform individual testing at each of these points, resulting in an inability to comprehensively and meticulously assess the impact resistance of the panel at different locations, thus affecting the accuracy of the test results. Summary of the Invention

[0004] This invention provides a test device for impact resistance testing of thermal insulation wall panels based on intelligent sensors, which solves the technical problem that existing devices in related technologies are difficult to perform individual testing on multiple test points of thermal insulation wall panels, resulting in an inability to comprehensively and meticulously evaluate the impact resistance of thermal insulation wall panels at different locations, thus affecting the accuracy of test results.

[0005] This invention provides a test device for impact resistance testing of thermal insulation wall panels based on intelligent sensors. The device includes a main body comprising an impact table with multiple detection heads; and an adjustment unit comprising a connecting frame mounted on the impact table. A fixed block is located at the center of the connecting frame, and multiple sets of movable blocks are arranged around the fixed block. Both the fixed block and the movable blocks are equipped with a switching mechanism and a telescopic mechanism. The switching mechanism controls the telescopic mechanism to extend and retract, controlling the corresponding detection head to extend according to different detection points. This allows for impact resistance testing of different locations on the thermal insulation panel without requiring adjustment of the insulation panel itself.

[0006] As a further optimization of the present invention, the switching mechanism includes air chambers respectively installed on a fixed block and a movable block. An air inlet pipe is installed on the air chamber. A first sealing rod is provided inside the air inlet pipe, and a first sealing block is installed on the first sealing rod. A cone is installed on the first sealing block, and a limiting ring is provided outside the cone. The air inlet pipe and the limiting ring are fixedly connected. A second spring is provided on the first sealing rod.

[0007] As a further optimization of the present invention, a limiting plate is installed inside the air intake pipe, and the limiting plate and the first sealing rod are slidably connected, and the limiting plate is provided with several openings.

[0008] As a further optimization of the present invention, the air chamber is also provided with an air outlet pipe, the air outlet pipe is provided with a second sealing rod, and a second sealing block is installed on the second sealing rod.

[0009] As a further optimization of the present invention, the telescopic mechanism includes an inner sleeve respectively installed on a fixed block and a movable block, and an outer sleeve slidably connected to the inner sleeve. The outer sleeve is fixedly connected to the detection head, and a third spring is installed between the inner sleeve and the outer sleeve.

[0010] As a further optimization of the present invention, a gasket is provided between the air outlet pipe and the second sealing block. The gasket is hollow inside and is made of flexible rubber.

[0011] As a further optimization of the present invention, the connecting frame is provided with a first lead screw mechanism and a second lead screw mechanism. By driving the first lead screw mechanism and the second lead screw mechanism to work, multiple sets of movable blocks are driven to move along the X-axis and Y-axis respectively, and the position of the movable blocks is adjusted.

[0012] As a further optimization of the present invention, the first lead screw mechanism includes a first bidirectional threaded lead screw and a first lead screw nut threadedly connected to the first bidirectional threaded lead screw, and a first guide rod is installed between every two sets of the first lead screw nuts;

[0013] The second lead screw mechanism includes a second bidirectional threaded lead screw and a second lead screw nut threadedly connected to the second bidirectional threaded lead screw, with a second guide rod installed between every two sets of the second lead screw nuts;

[0014] The first guide rod and the second guide rod are slidably connected to multiple sets of movable blocks corresponding to their positions.

[0015] As a further optimization of the present invention, a first guide frame is installed inside the connecting frame, and a second guide frame is symmetrically installed on both sides of the first guide frame. The fixing block is fixedly connected to the first guide frame. The first guide frame and the second guide frame are used to limit the movement of multiple sets of movable blocks on the X-axis and Y-axis, so that the movable blocks remain stable when moving.

[0016] As a further optimization of the present invention, the connecting frame is also provided with a first sliding groove and a second sliding groove, through which the first guide rod and the second guide rod are moved and guided.

[0017] The beneficial effects of the present invention are as follows: The present invention controls the telescopic mechanism to extend and retract by switching mechanism, thereby driving the detection head to extend and retract synchronously. When performing impact resistance testing on different detection positions of the insulation board, there is no need to adjust the insulation board. By controlling the telescopic mechanism to extend and retract at the corresponding position by switching mechanism, the detection head can perform impact resistance testing on the detection point during the fall of the impact table.

[0028] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0029] according to Figure 1 and Figure 2 As shown, a test device for impact resistance testing of thermal insulation wall panels based on intelligent sensors includes a device body 10. The device body 10 includes a workbench 11, and a connecting frame 12 is provided above the workbench 11. Guide columns 13 are symmetrically installed between the workbench 11 and the connecting frame 12, and an impact table 14 is provided on the guide columns 13. Sliding sleeves 15 are symmetrically installed on the impact table 14 and are slidably connected to the guide columns 13. Multiple detection heads 16 are provided on the impact table 14, and the detection heads 16 are used to perform impact resistance testing on the thermal insulation wall panels. A traction frame 17 and a power unit 18 are also installed on the workbench 11.

[0030] In practice, a traction rope is connected to the traction frame 17, which passes through the pulley block on the impact table 14, and the other end of the traction rope passes through the pulley block on the traction frame 17 and is connected to the power unit 18.

[0031] When the insulation wall panel is subjected to impact resistance testing, the control power device 18 is wound up and released to complete the winding and unwinding operation of the impact table 14, so that the testing head 16 can perform impact resistance testing on the insulation wall panel.

[0032] according to Figure 3 As shown, in order to buffer the connection between the guide post 13 and the sliding sleeve 15 on the impact table 14 and to protect the impact table 14, the guide post 13 is provided with a pad 131 and a first spring 132. The two ends of the first spring 132 are fixedly connected to the worktable 11 and the pad 131 respectively. When the impact table 14 falls to the lowest point, the sliding sleeve 15 and the pad 131 come into contact, and the impact table 14 is buffered and protected by the first spring 132.

[0033] according to Figure 3 and Figure 4 As shown, an adjustment unit 20 is provided between the impact table 14 and the detection head 16. The adjustment unit 20 includes a connecting frame 21 installed on the impact table 14, and a first lead screw mechanism 22 and a second lead screw mechanism 23 are provided on the connecting frame 21. A fixed block 24 is provided in the middle position inside the connecting frame 21, and multiple sets of movable blocks 25 are provided around the fixed block 24.

[0034] Specifically, by driving the first lead screw mechanism 22 and the second lead screw mechanism 23 to work, multiple sets of movable blocks 25 are driven to move along the X-axis or Y-axis respectively, and the position of the movable blocks 25 is adjusted so that the movable blocks 25 move closer to the center of the fixed block 24 or spread outwards. That is to say, they move closer to the fixed block 24 or away from the fixed block 24.

[0035] according to Figure 6 As shown, the first lead screw mechanism 22 includes a first bidirectional threaded lead screw 221 with bearings connected to both sides of the connecting frame 21, and a first lead screw nut 222 is threaded to both sides of the outer side of the first bidirectional threaded lead screw 221. The two sets of first bidirectional threaded lead screws 221 are connected to each other through a first belt pulley transmission mechanism 223. A first guide rod 224 is installed between each two sets of first lead screw nuts 222, and the first guide rod 224 is slidably connected to multiple sets of movable blocks 25 corresponding to its position.

[0036] according to Figure 6 As shown, the second lead screw mechanism 23 includes a second bidirectional threaded lead screw 231 with bearings connected to the other two sides of the connecting frame 21, and a second lead screw nut 232 is threaded to both sides of the outer side of the second bidirectional threaded lead screw 231. The two sets of second bidirectional threaded lead screws 231 are connected to each other through a second belt pulley transmission mechanism 233. A second guide rod 234 is installed between each two sets of second lead screw nuts 232, and the second guide rod 234 is slidably connected to multiple sets of movable blocks 25 corresponding to its position.

[0037] When it is necessary to adjust the position of multiple sets of movable blocks 25, the position of multiple sets of movable blocks 25 can be adjusted by manual operation or by using a motor to drive the first bidirectional threaded screw 221 and the second bidirectional threaded screw 231.

[0038] It should be noted that, according to Figure 5 As shown, a first guide frame 211 is installed inside the connecting frame 21, and a second guide frame 212 is symmetrically installed on both sides of the first guide frame 211. The end of the second guide frame 212 away from the first guide frame 211 is fixedly connected to the inner wall of the connecting frame 21. Support plates 213 are installed on both sides inside the first guide frame 211, and a fixing block 24 is fixedly connected to the first guide frame 211.

[0039] The first guide frame 211 and the second guide frame 212 are used to limit the movement of multiple sets of movable blocks 25 on the X and Y axes, so that the movable blocks 25 remain stable during movement. In addition, the first guide rod 224 and the second guide rod 234 are provided to ensure that the movable blocks 25 at the four corners inside the connecting frame 21 remain stable during movement.

[0040] Furthermore, the connecting frame 21 is also provided with a first sliding groove 214 and a second sliding groove 215, which correspond to the first guide rod 224 and the second guide rod 234. In this embodiment, the first guide rod 224 and the second guide rod 234 are guided by the first sliding groove 214 and the second sliding groove 215, thereby improving the stability of the movement of the first guide rod 224 and the second guide rod 234.

[0041] according to Figure 7 As shown, both the fixed block 24 and the movable block 25 are equipped with a switching mechanism 26 and a telescopic mechanism 27. The fixed block 24 and the movable block 25 are respectively connected to the detection head 16 through the telescopic mechanism 27. In this embodiment, the telescopic mechanism 27 is controlled to extend and retract by the switching mechanism 26, thereby driving the detection head 16 to extend and retract synchronously. This is so that when performing impact resistance testing on different detection positions of the insulation board, there is no need to adjust the insulation board. By controlling the telescopic mechanism 27 to extend to the corresponding position by the switching mechanism 26, the detection head 16 can perform impact resistance testing on the detection point during the descent of the impact table 14.

[0042] according to Figure 8 and Figure 9As shown, the switching mechanism 26 includes an air chamber 261 installed on a fixed block 24 and a movable block 25 respectively. An air inlet pipe 262 is installed on the air chamber 261. A first sealing rod 264 is provided inside the air inlet pipe 262, and a first sealing block 265 is installed on the first sealing rod 264. A cone 266 is installed on the first sealing block 265, and a limiting ring 267 is provided outside the cone 266. The air inlet pipe 262 and the limiting ring 267 are fixedly connected. A limiting plate 268 is installed inside the air inlet pipe 262, and the limiting plate 268 is slidably connected to the first sealing rod 264. Several openings are provided on the limiting plate 268. A second spring 269 is provided on the first sealing rod 264. One end of the second spring 269 is fixedly connected to the first sealing block 265, and the other end of the second spring 269 is fixedly connected to the limiting plate 268.

[0043] The gas chamber 261 is also provided with an air outlet pipe 263. The air outlet pipe 263 is provided with a second sealing rod 2610 inside, and a second sealing block 2611 is installed on the second sealing rod 2610. The first sealing rod 264 and the second sealing rod 2610 are fixedly connected by a connecting plate 2612.

[0044] Furthermore, a gasket 2613 is provided between the vent pipe 263 and the second sealing block 2611. The gasket 2613 is hollow inside and is made of flexible rubber.

[0045] according to Figure 8 As shown, the telescopic mechanism 27 includes an inner sleeve 271 that is respectively installed on the fixed block 24 and the movable block 25, and an outer sleeve 272 that is slidably connected to the inner sleeve 271. The outer sleeve 272 is fixedly connected to the detection head 16, and a third spring 273 is installed between the inner sleeve 271 and the outer sleeve 272.

[0046] In practice, the air intake pipe 262 is connected to the external air supply equipment via a flexible hose. It should be noted that during operation, the external air supply equipment controls the air to enter the air intake pipe 262. The air pressure pushes the first sealing block 265 and the cone head 266, causing the second spring 269 to elastically deform. This controls the first sealing rod 264 to move the second sealing rod 2610 synchronously. At this time, the second sealing block 2611 adheres to the washer 2613, closing the air outlet pipe 263. As a large amount of gas flows in, the second sealing block 2611 continuously compresses the washer 2613, causing the washer 2613 to deform.

[0047] When a large amount of gas rushes in, it fully expands the inner sleeve 271 and the outer sleeve 272, causing the third spring 273 to undergo elastic deformation, which extends a set of detection heads 16 connected to it outward. At this time, the other sets of detection heads 16 remain in a retracted state.

[0048] When the detection head 16 needs to be reset, the air supply is stopped by the external air supply device. The second spring 269 drives the first sealing rod 264 to reset, so that the first sealing rod 264 drives the second sealing rod 2610 to move synchronously, so that the second sealing rod 2610 is reset, opening the air outlet pipe 263. And through the setting of the third spring 273, the inner sleeve 271 and the outer sleeve 272 are driven to reset, controlling the detection head 16 to return to the retracted state.

[0049] The embodiments of this specific implementation have been described above. However, this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.
