Description

Technical Field

[0001] This disclosure relates to the field of testing equipment technology, and in particular to a deformation detection device for hardness impact testing of color steel plates. Background Technology

[0002] As a composite material consisting of a substrate and a surface coating, color steel sheet is widely used in building envelopes, appliance housings, transportation and other fields. Its impact resistance directly determines its ability to resist external collisions, falling objects and other scenarios during use. Hardness impact testing is one of the core methods to evaluate this performance. It aims to simulate the impact load under actual working conditions and determine whether the color steel sheet has failed due to coating peeling, substrate deformation, cracking and other failure phenomena.

[0003] Currently, when conducting impact tests on color steel sheets, the sheets are typically clamped and then impacted using a drop hammer impact testing machine. However, after the impact, because color steel sheets usually have a certain degree of elasticity, they may undergo continuous deformation. After a certain period of stabilization, the sheet is removed for measurement, which fails to detect the amount of change in the sheet during the deformation process. Consequently, the rebound effect of the sheet cannot be detected, affecting the detection range of the device. Summary of the Invention

[0004] This disclosure aims to at least partially address one of the technical problems in the related art.

[0005] Therefore, the purpose of this disclosure is to provide a deformation detection device for hardness impact testing of color steel plates.

[0006] To achieve the above objectives, this disclosure provides a deformation detection device for hardness impact testing of color steel plates, comprising: a support structure, on which a sliding structure and an auxiliary structure are mounted; a placement structure is slidably fitted on the sliding structure; a color steel plate is placed on the placement structure; multiple detection structures are installed within the placement structure, each detection structure corresponding to the color steel plate; the auxiliary structure supports the placement structure to prevent excessive pressure on the color steel plate from being transmitted to the sliding structure and causing damage to the sliding structure; and a pressing structure, which is slidably connected to the support structure; multiple fixing structures and pressure-applying structures are mounted on the lower side of the pressing structure, each fixing structure corresponding to the pressure-applying structure; the fixing structures control the impact intensity of the pressure-applying structures; and the fixing structures press down and fix the color steel plate.

[0007] Optionally, the support structure includes: a base, on which a support frame is fixed; a sliding structure including a first electric slide rail fixed to the base; an auxiliary structure including a support slide rail fixed to the base; and multiple support plates fixed to the support frame. The support plates assist in supporting the placement structure and the color steel plate, and the first electric slide rail drives the placement structure to slide. The support slide rail limits the placement structure to prevent the first electric slide rail from being subjected to excessive pressure and thus damaged.

[0008] Optionally, the placement structure includes: a support base, which is fixedly connected to the output end of a first electric slide rail and slidably connected to the support slide rail. A placement plate is mounted on the upper side of the support base, and the color steel plate is placed on the upper side of the placement plate. Multiple first electric cylinders are fixed on the support base, and the output ends of the first electric cylinders are fixedly connected to the placement plate. A first through groove is opened in the middle of the placement plate. When the color steel plate is subjected to impact testing, the color steel plate is placed on the placement plate, and then the placement plate is slid by the first electric slide rail, thereby moving the color steel plate to the position to be tested. At this time, the placement plate is located above the support plate, and the support plate provides auxiliary support to the placement plate. When the color steel plate is subjected to pressure testing, the color steel plate is placed on the support plate, the first electric cylinder is activated, and the position of the placement plate is adjusted to below the support plate. The placement plate is then slid to the position to be tested by the first electric slide rail, thereby monitoring the degree of deformation of the color steel plate.

[0009] Optionally, the detection structure includes: multiple distance sensors, which are fixed on the support base and located directly below the first through slot. The distance sensors detect the positional changes of the color steel plate after being impacted or pressured to monitor the degree of deformation of the color steel plate; and an integrated machine, which is fixed on the support frame. The integrated machine processes the data monitored by the distance sensors and displays the results. It also controls the operation of the first electric slide rail, the first electric cylinder, the pressing structure, the fixing structure, and the pressurizing structure.

[0011] Optionally, the fixing structure includes: multiple first telescopic rods and multiple second telescopic rods; wherein the first telescopic rods and the second telescopic rods have the same structure, and both the first telescopic rods and the second telescopic rods are fixedly connected to the sliding frame, the first telescopic rods are located on the upper side of the placement plate, and the second telescopic rods are located on the upper side of the support plate; wherein both the first telescopic rods and the second telescopic rods include a first rod body and a second rod body, the first rod body and the second rod body are slidably connected, a locking structure is installed between the first rod body and the second rod body, and multiple first springs are fixed between the first rod body and the second rod body; wherein, when the color steel plate is pressed down and fixed, the sliding frame slides down so that the second rod body contacts the color steel plate, and as the sliding frame slides, the first springs are compressed. At this time, the position of the second rod body is fixed by the locking structure, so that the color steel plate can be pressed and fixed without changing the position of the sliding frame.

[0012] Optionally, the locking structure includes: a positioning block; a cavity is provided at the end of the second rod; multiple second through slots are provided on the periphery of the cavity; the second through slots correspond to the positioning block; multiple second springs are fixed between the positioning block and the cavity; multiple positioning slots are provided inside the first rod; the positioning slots correspond to the positioning block; a third electric cylinder is fixed inside the cavity; and a push block is fixed at the output end of the third electric cylinder. When the position of the second rod needs to be fixed, the third electric cylinder is activated, pushing the push block upwards. The push block has a conical structure and presses the positioning block peripherally, causing the positioning block to slide out and enter the positioning slot, thus fixing the position of the second rod.

[0013] Optionally, the pressurizing structure includes: a second electric cylinder, which is fixed to the upper side of the sliding frame, and a fixed cylinder is fixed to the lower side of the sliding frame. A limit frame is slidably fitted inside the fixed cylinder. A connecting rod is fixed between two adjacent first telescopic rods, and a push rod is fixed on the connecting rod. The limit frame is fixedly connected to the push rod. A pressure rod is slidably fitted inside the fixed cylinder. A positioning structure is installed between the pressure rod and the limit frame, and the positioning structure corresponds to the second electric cylinder. When the first telescopic rod extends or retracts, it pushes the limit frame up and down through the push rod to slide, thereby adjusting the position of the limit frame. The position of the pressure rod's rebound is selected according to the position of the limit frame, thereby controlling the magnitude of the instantaneous impact pressure.

[0014] Optionally, the pressurizing structure further includes a third spring and a fourth spring; wherein the third spring and the fourth spring are both fixed inside the fixed cylinder, and a sliding plate is fixed to the top of the pressure rod. When the sliding plate slides upward, it squeezes the third spring. When the sliding plate is released, the instantaneous impact generated by the rebound of the third spring presses the color steel plate. The fourth spring limits and buffers the sliding plate to prevent the sliding plate from being damaged by impact.

[0015] Optionally, the positioning structure includes: an insert block; a first sliding groove is provided on the sliding plate, the first sliding groove is slidably connected to the insert block; a pull rod is fixed at the output end of the second electric cylinder, a slot is provided on the pull rod, the slot corresponds to the insert block; a limit rod is fixed on the limit frame; multiple second sliding grooves are provided on the periphery of the fixed cylinder, the second sliding grooves correspond to the limit frame; a fifth spring is fixed between the insert block and the first sliding groove; a groove is provided on the insert block, the groove corresponds to the limit rod; wherein, when the sliding plate slides upward, the limit rod inserts into the groove and drives the insert block to slide in the first sliding groove, causing the insert block to separate from the slot, thereby the third spring rebounds and pushes the sliding plate to slide, causing the pressure rod to generate downward impact pressure, which can then be used to inspect the color steel plate.

During impact testing, the deformation of the color steel plate can be continuously detected and the change curve can be plotted through the detection structure.

This allows for the detection of the rebound effect of the color steel plate. In addition to impact testing, the device can also continuously apply static pressure to the color steel plate through the pressure structure, thereby expanding the measurement range of the device and making it more flexible to use.

[0017] 2. When pressure is applied to the color steel plate, the support plate can be used to provide auxiliary support, and the placement structure can be limited by the auxiliary structure to prevent the placement structure from being damaged by excessive pressure, thereby ensuring the transportation effect of the color steel plate and extending the service life of the device.

[0018] 3. The color steel plate can be extruded and fixed by a fixed structure, thereby ensuring the stability of the color steel plate during operation. Furthermore, the magnitude of the instantaneous impact force applied by the pressure structure can be adjusted by the fixed structure, thereby enabling the color steel plate to be tested for deformation under different impact forces, thus expanding the detection range of the device.

[0021] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0022] like Figures 1 to 10 As shown in the present disclosure, an embodiment of the device for detecting deformation of color steel plate in a hardness impact test includes: a support structure, on which a sliding structure and an auxiliary structure are mounted; a placement structure is slidably fitted on the sliding structure; a color steel plate is placed on the placement structure; multiple detection structures are installed inside the placement structure, and the detection structures correspond to the color steel plate; the auxiliary structure supports the placement structure to prevent the color steel plate from being subjected to excessive pressure that could be transmitted to the sliding structure and cause damage to the sliding structure; and a pressing structure, which is slidably connected to the support structure; multiple fixing structures and pressure-applying structures are mounted on the lower side of the pressing structure, and the fixing structures correspond to the pressure-applying structures; the fixing structures control the impact intensity of the pressure-applying structures, and the fixing structures press down and fix the color steel plate.

[0023] In this embodiment, the support structure includes: a base 101, a support frame 102 fixed on the base 101, a sliding structure including a first electric slide rail 103 fixed on the base 101, an auxiliary structure including a support slide rail 104 fixed on the base 101, and a plurality of support plates 105 fixed on the support frame 102; wherein, the support plates 105 assist in supporting the placement structure and the color steel plate, and the first electric slide rail 103 drives the placement structure to slide, and the support slide rail 104 limits the placement structure to prevent the first electric slide rail 103 from being damaged by excessive pressure.

[0024] Specifically, activating the first electric slide rail 103 causes the support base 201 to slide. The support base 201 slides on the support slide rail 104. When the support base 201 is subjected to significant pressure, the support slide rail 104 provides auxiliary support and disperses the pressure exerted by the support base 201 on the first electric slide rail 103. This prevents damage to the first electric slide rail 103 due to excessive pressure, extends its service life, and ensures the normal movement of the support base 201. This allows the support base 201 to transport the color steel plate effectively, facilitating the testing and inspection of its deformation and improving the efficiency of the testing and inspection work.

[0025] The placement structure includes: a support base 201, which is fixedly connected to the output end of a first electric slide rail 103 and slidably connected to a support slide rail 104; a placement plate 203 is mounted on the upper side of the support base 201; a color steel plate is placed on the upper side of the placement plate 203; multiple first electric cylinders 202 are fixed on the support base 201; the output ends of the first electric cylinders 202 are fixedly connected to the placement plate 203; and a first through groove 205 is formed in the middle of the placement plate 203. When performing impact testing on the color steel plate, the color steel plate is placed on the placement plate. The first electric slide rail 103 drives the placement plate 203 to slide, thereby moving the color steel plate to the position to be tested. At this time, the placement plate 203 is located above the support plate 105, and the support plate 105 provides auxiliary support for the placement plate 203. When the color steel plate is subjected to pressure testing, the color steel plate is placed on the support plate 105, the first electric cylinder 202 is started, and the position of the placement plate 203 is adjusted to be below the support plate 105. The first electric slide rail 103 drives the placement plate 203 to slide to the position to be tested, so that the degree of deformation of the color steel plate can be monitored.

[0026] Specifically, when impact testing of the color steel sheet is required, the color steel sheet is placed on the placement plate 203. Then, the first electric slide rail 103 is activated, causing the support base 201 to move, which in turn moves the placement plate 203, thus sliding the color steel sheet to the position to be tested. Then, the first electric cylinder 202 is activated, causing the placement plate 203 to slide downwards until it is limited by the support plate 105. At this point, the color steel sheet comes into contact with the support plate 105, so that both the placement plate 203 and the support plate 105 simultaneously support the color steel sheet. The support plate 105 also serves to support and limit the placement plate 203, preventing it from moving or impacting the first electric cylinder 202 under large impact pressure. This creates significant pressure, thereby extending the service life of the first electric cylinder 202, ensuring the stability of the color steel plate during the test, and guaranteeing the accuracy of the device in detecting the impact deformation of the color steel plate. When static pressure monitoring of the color steel plate requires continuous pressure, the color steel plate is placed on two support plates 105, and then the first electric cylinder 202 is activated to adjust the position of the placement plate 203 to below the support plate 105. The placement plate 203 is then slid to the position to be tested via the first electric slide rail 103. At this time, static pressure is applied to the color steel plate. The placement plate 203 does not contact the color steel plate, and the deformation of the color steel plate is dynamically detected only by the distance sensor 204 on the support base 201. This expands the applicability of the device and makes the device more flexible in testing color steel plates.

[0027] The detection structure includes: multiple distance sensors 204, which are fixed on the support base 201 and located directly below the first through slot 205. The distance sensors 204 detect the positional changes of the color steel plate after being impacted or pressured to monitor the degree of deformation of the color steel plate; and an integrated machine, which is fixed on the support frame 102. The integrated machine processes the data monitored by the distance sensors 204 and displays the results. The integrated machine also controls the operation of the first electric slide rail 103, the first electric cylinder 202, the pressing structure, the fixing structure, and the pressurizing structure.

[0028] Specifically, when impact or static pressure is applied to the color steel plate, the dynamic position change of the color steel plate can be detected by the distance sensor 204. When the color steel plate deforms, the position change of a certain part of the color steel plate is different according to different deformation. Therefore, the deformation can be detected by detecting the position change of the color steel plate by the distance sensor 204, and the rebound effect of the color steel plate can be detected by the real-time change curve, thereby expanding the detection range of the device and ensuring the accuracy of the detection results.

[0029] The pressing structure includes: a sliding frame 302, a second electric slide rail 301 fixed on the support frame 102, the output end of the second electric slide rail 301 fixedly connected to the sliding frame 302, an integrated machine connected to the second electric slide rail 301 via a data cable, and the integrated machine controlling the opening and closing and sliding distance of the second electric slide rail 301. The fixing structure and the pressing structure are both fixedly connected to the sliding frame 302. The sliding frame 302 slides up and down, causing the fixing structure and the pressing structure to slide up and down, which is used to assist in fixing and pressing the color steel plate, ensuring stability during the color steel plate testing process, and enabling more accurate testing of the color steel plate.

[0030] Specifically, activating the second electric slide rail 301 causes the sliding frame 302 to slide up and down, which in turn causes the first telescopic rod 401, the second telescopic rod 402, and the fixed cylinder 503 fixed on the sliding frame 302 to slide up and down. This can be used to assist in pressing down and fixing the color steel plate and applying pressure, thereby ensuring the stability of the color steel plate during testing. It can also prevent the first telescopic rod 401, the second telescopic rod 402, and the fixed cylinder 503 from limiting the color steel plate during the sliding process, thus facilitating the loading and unloading of the color steel plate and improving the testing efficiency of the color steel plate.

[0031] The fixing structure includes: a plurality of first telescopic rods 401 and a plurality of second telescopic rods 402; wherein the first telescopic rods 401 and the second telescopic rods 402 have the same structure, and both the first telescopic rods 401 and the second telescopic rods 402 are fixedly connected to the sliding frame 302. The first telescopic rods 401 are located on the upper side of the placement plate 203, and the second telescopic rods 402 are located on the upper side of the support plate 105; wherein both the first telescopic rods 401 and the second telescopic rods 402 include a first rod body 403 and a second rod body 404, and the first rod body 403 and the second rod body 404 are fixedly connected to the sliding frame 302. The two rods 404 are slidably connected. A locking structure is installed between the first rod 403 and the second rod 404. Multiple first springs 405 are fixed between the first rod 403 and the second rod 404. When the color steel plate is pressed down and fixed, the sliding frame 302 slides down so that the second rod 404 contacts the color steel plate. As the sliding frame 302 slides, the first springs 405 are compressed. At this time, the position of the second rod 404 is fixed by the locking structure, so that the color steel plate can be pressed and fixed without changing the position of the sliding frame 302.

[0032] Specifically, when the sliding frame 302 slides downwards, the second rod 404 comes into contact with the color steel plate, causing the second rod 404 to press upwards relative to the plate. The first spring 405 is compressed, and the first spring 405 generates a counter-elastic force to press the color steel plate, thus pressing and fixing the color steel plate downwards. This ensures the stability of the color steel plate and prevents it from shaking due to large impact forces. This ensures that the device can accurately detect the deformation of the color steel plate, thereby improving the accuracy of the device and ensuring the accuracy of the test results. Furthermore, the sliding connection between the first rod 403 and the second rod 404 does not impose a large limit on the downward pressing position of the sliding frame 302, thereby expanding the detection range of the device.

[0033] The locking structure includes: a positioning block 407; a cavity 409 is provided at the end of the second rod 404; multiple second through slots 410 are provided on the periphery of the cavity 409, corresponding to the positioning block 407; multiple second springs 408 are fixed between the positioning block 407 and the cavity 409; multiple positioning slots 406 are provided in the first rod 403, corresponding to the positioning block 407; a third electric cylinder 411 is fixed in the cavity 409; and a push block 412 is fixed at the output end of the third electric cylinder 411. When it is necessary to fix the position of the second rod 404, the third electric cylinder 411 is activated, and the third electric cylinder 411 pushes the push block 412 upward. The push block 412 has a conical structure and presses the positioning block 407 to the periphery. The positioning block 407 slides out and enters the positioning slot 406, thereby fixing the position of the second rod 404.

[0034] Specifically, when it is necessary to fix the lengths of the first telescopic rod 401 and the second telescopic rod 402, the third electric cylinder 411 is activated, causing the third electric cylinder 411 to push the push block 412 upwards. This push block 412 then presses against the positioning block 407, causing the positioning block 407 to slide out of the second through groove 410 and into the positioning slot 406. This creates a locking relationship between the positioning block 407 and the positioning slot 406, compressing the second spring 408, thus fixing the lengths of the first telescopic rod 401 and the second telescopic rod 402. The length of the first telescopic rod 401 and the second telescopic rod 402 is fixed. When it is necessary to extend or retract the length of the first telescopic rod 401 and the second telescopic rod 402, the third electric cylinder 411 is activated, which pulls the push block 412 downward. As a result, the push block 412 no longer presses and limits the positioning block 407. At this time, the second spring 408 rebounds and drives the positioning block 407 to reset. The positioning block 407 and the positioning slot 406 lose their engagement relationship, and the length of the first telescopic rod 401 and the second telescopic rod 402 can be extended or retracted.

[0035] The pressurizing structure includes: a second electric cylinder 303, which is fixed to the upper side of the sliding frame 302. A fixed cylinder 503 is fixed to the lower side of the sliding frame 302. A limit frame 506 is slidably fitted inside the fixed cylinder 503. A connecting rod 501 is fixed between two adjacent first telescopic rods 401. A push rod 502 is fixed on the connecting rod 501. The limit frame 506 is fixedly connected to the push rod 502. A pressure rod 509 is slidably fitted inside the fixed cylinder 503. A positioning structure is installed between the pressure rod 509 and the limit frame 506. The positioning structure corresponds to the second electric cylinder 303. When the first telescopic rod 401 extends or retracts, it pushes the limit frame 506 up and down through the push rod 502 to adjust the position of the limit frame 506. The position of the pressure rod 509 is selected according to the position of the limit frame 506 to control the instantaneous impact pressure.

[0036] Specifically, when static pressure needs to be applied, the second electric slide rail 301 is activated, causing the sliding frame 302 to slide downwards, which in turn causes the fixed cylinder 503 to slide downwards. The second electric cylinder 303 is then activated, which pushes the pressure rod 509 downwards. The pressure rod 509 then contacts the color steel plate, thus applying static pressure to the color steel plate.

[0037] The pressurizing structure further includes: a third spring 510 and a fourth spring 511; wherein, the third spring 510 and the fourth spring 511 are both fixed inside the fixed cylinder 503, and a sliding plate 508 is fixed to the top of the pressure rod 509. When the sliding plate 508 slides upward, it compresses the third spring 510. When the sliding plate 508 is released, the instantaneous impact generated by the rebound of the third spring 510 pressurizes the color steel plate. The fourth spring 511 limits and buffers the sliding plate 508 to prevent the sliding plate 508 from being damaged by impact. The positioning structure includes: an insert block 601. A first sliding groove 505 is provided on the sliding plate 508. The first sliding groove 505 is slidably connected to the insert block 601. A pull rod 504 is fixed to the output end of the second electric cylinder 303. A slot 6 is provided on the pull rod 504. 02. The slot 602 corresponds to the insert block 601. A limit rod 507 is fixed on the limit frame 506. Multiple second sliding grooves 512 are opened on the periphery of the fixed cylinder 503. The second sliding grooves 512 correspond to the limit frame 506. A fifth spring 604 is fixed between the insert block 601 and the first sliding groove 505. A groove 603 is opened on the insert block 601. The groove 603 corresponds to the limit rod 507. When the sliding plate 508 slides upward, the limit rod 507 inserts into the groove 603 and drives the insert block 601 to slide in the first sliding groove 505, so that the insert block 601 separates from the slot 602. Then, the third spring 510 rebounds and pushes the sliding plate 508 to slide, so that the pressure rod 509 generates downward impact pressure, which can be used to inspect the color steel plate.

[0038] Specifically, when impact pressure needs to be applied to the device, when the first telescopic rod 401 is extended and retracted by the sliding frame 302, the first telescopic rod 401 will push the limiting frame 506 to slide up and down through the push rod 502, thereby adjusting the magnitude of the applied impact force. After adjustment, the length of the first telescopic rod 401 is locked, and then the second electric cylinder 303 is activated, so that the second electric cylinder 303 pulls the pressure rod 509 through the pull rod 504, thereby squeezing the third spring 510 by the sliding plate 508 until the limiting rod 507 is inserted into the groove 603, so that the limiting rod 507 drives the insert 601 to slide in the first sliding groove 505, so that the insert 601 separates from the slot 602, thereby the third spring 510 rebounds and pushes the sliding plate 508 to slide, so that the pressure rod 509 generates downward impact pressure, thus realizing the monitoring of the deformation of the color steel plate under instantaneous impact.

[0039] Workflow: Place the color steel plate on the placement plate 203, then activate the first electric slide rail 103, causing it to move the support base 201, which in turn moves the placement plate 203, thus sliding the color steel plate to the position to be tested. Then, activate the first electric cylinder 202, causing it to slide the placement plate 203 downwards until it is limited by the support plate 105. At this point, the color steel plate contacts the support plate 105, and both the placement plate 203 and the support plate 105 simultaneously support the color steel plate. Activate the second electric slide rail 301, which will then move the sliding frame 302 up and down, thereby moving the first telescopic rod 401 and the second telescopic rod 402 fixed on the sliding frame 302. The rod 402 and the fixed cylinder 503 slide up and down, which can be used to assist in pressing down and fixing the color steel plate and applying pressure, thereby ensuring the stability of the color steel plate during the test. When the sliding frame 302 slides down, the second rod 404 comes into contact with the color steel plate, so that the second rod 404 is relatively pressed upward, and the first spring 405 is compressed. At this time, the first spring 405 generates a counter-elastic force to press the color steel plate, which can press down and fix the color steel plate. The third electric cylinder 411 is activated, so that the third electric cylinder 411 pushes the push block 412 relatively upward, so that the push block 412 presses the positioning block 407, so that the positioning block 407 slides out from the second through groove 410 and enters the positioning slot 406, so that the positioning block 407 and the positioning slot 406 are in contact. When the first telescopic rod 401 and the second telescopic rod 402 are in a snap-fit ​​relationship, the second spring 408 is compressed, thus fixing their lengths. When it is necessary to extend or retract the lengths of the first telescopic rod 401 and the second telescopic rod 402, the third electric cylinder 411 is activated, causing it to pull the push block 412 downwards. This removes the push block 412 from the positioning block 407, causing it to revert to its original position. The second spring 408 then rebounds, resetting the positioning block 407. The positioning block 407 loses its snap-fit ​​relationship with the positioning slot 406, allowing for adjustment of the lengths of the first telescopic rod 401 and the second telescopic rod 402. When impact pressure needs to be applied to the device, the first telescopic rod 401 extends or retracts due to the up-and-down sliding motion of the sliding frame 302. The first telescopic rod 401 pushes the limiting frame 506 up and down through the push rod 502 to adjust the magnitude of the applied impact force. After adjustment, the length of the first telescopic rod 401 is locked, and then the second electric cylinder 303 is activated, which pulls the pressure rod 509 through the pull rod 504. This causes the sliding plate 508 to compress the third spring 510 until the limiting rod 507 is inserted into the groove 603. The limiting rod 507 then drives the insert 601 to slide in the first sliding groove 505, causing the insert 601 to separate from the slot 602. The third spring 510 then rebounds and pushes the sliding plate 508 to slide, causing the pressure rod 509 to generate downward impact pressure. This allows for the monitoring of the deformation of the color steel plate under instantaneous impact.

[0040] When static pressure monitoring of the color steel plate requires continuous pressure application, the color steel plate is placed on two support plates 105. Then, the first electric cylinder 202 is activated to adjust the position of the placement plate 203 to below the support plate 105. The placement plate 203 is slid to the position to be tested via the first electric slide rail 103. At this time, static pressure is applied to the color steel plate. The placement plate 203 does not contact the color steel plate. The deformation of the color steel plate is dynamically detected only by the distance sensor 204 on the support base 201. Then, the second electric slide rail 301 is activated, which causes the sliding frame 302 to slide downward, thereby causing the fixed cylinder 503 to slide downward. The second electric cylinder 303 is activated, which pushes the pressure rod 509 downward. The pressure rod 509 contacts the color steel plate, thus applying static pressure to the color steel plate.
