[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-2 The present invention provides a technical solution: a multi-functional air defense door debugging and testing platform, including a shell 1, a track 2, a support component 3, a safety component 4, a testing component 5 and an air inlet 16. The support component 3 is located below the shell 1 and is used to place the air defense door panel to be tested. Two sets of tracks 2 are symmetrically arranged at the left and right ends of the support component 3 for transporting the air defense door panel. The safety component 4 is located inside the shell 1. Several sets of testing components 5 are sequentially installed above the safety component 4. For example, three sets of testing components 5 are provided.

[0037] The interior of the outer casing 1 is equipped with several connecting blocks 15, which are fixedly connected to the safety component 4 and the detection component 5 respectively to provide support force. A gate 10 is installed on the lower end face of the outer casing 1. The gate 10 is the prior art. The gate 10 is located between the left end track 2 and the support component 3. The right end track 2 is used to transport the door panel of the air defense door to be tested to the top of the support component 3. The left end track 2 is used to transport the door panel of the air defense door after testing to the subsequent stage.

[0038] The following is a supplementary explanation based on the above structure: Before the test begins, the gate 10 is in the closed state. The gate 10 isolates the left end track 2 from the support component 3, and the right end track 2 is connected to the support component 3. The door panel of the air-raid shelter door to be tested is transported to the top of the support component 3 through the right end track 2. Since the gate 10 isolates the support component 3 from the left end track 2, the air-raid shelter door panel cannot move to the left end track 2 through the support component 3. The gate 10 causes the air-raid shelter door panel to be tested to stop above the support component 3.

[0039] The lower end face of the outer casing 1 is symmetrically provided with motor 3 9. Motor 3 9 is a bidirectional motor. The output end of motor 3 9 is connected to lead screw 3 6. The lower end bearing of lead screw 3 6 is connected to a base. Each set of lead screw 3 6 is threadedly connected to a ring 3 7. Each set of ring 3 7 is connected to a clamp 3 8. The clamp 3 8 includes a hydraulic cylinder set inside. The output end of the hydraulic cylinder is connected to a gripper.

[0040] The following is a supplementary explanation based on the above structure: Start the hydraulic cylinder inside clamp 3 8. The hydraulic cylinder pushes the gripper to retract, causing the gripper to clamp the support component 3. When the hydraulic cylinder pulls the gripper, the gripper releases the support component 3. Start motor 3 9. Motor 3 9 drives lead screw 3 6 to rotate. The thread of lead screw 3 6 pushes ring 3 7 to move along the axis of lead screw 3 6. By controlling different rotation directions through motor 3 9, ring 3 7 can move up or down along lead screw 3 6. Ring 3 7 drives clamp 3 8 to move synchronously, and clamp 3 8 drives support component 3 to move synchronously.

[0041] refer to Figures 3 to 6The support component 3 includes a base plate 301. A sealing ring 2 is installed around the outer side of the support component 3. A baffle 306 is symmetrically installed along the long side above the base plate 301. The height of the baffle 306 is less than the thickness of the air defense door panel. A ring of light sensors 302 is laid around the central area on the upper surface of the base plate 301. Several sets of air pressure sensors 303 are evenly installed around the outer ring of the light sensors 302. Several sets of rollers 305 are installed in the middle area of ​​the base plate 301. The rollers 305 are used to place the air defense door panel to be tested. Columns 304 with the same structure are fixedly installed at the diagonal positions of the base plate 301. Each set of columns 304 is divided into a first segment 3041, a second segment 3042, and a third segment 3043 from top to bottom. The first segment 3041 is located above the base plate 301, the third segment 3043 is located below the base plate 301, and the second segment 3042 is fixedly connected to the base plate 301.

[0042] The following is a supplementary explanation based on the above structure: Clamp 38 holds the third segment 3043. When the door panel of the air defense door to be tested is above the support component 3, the motor 39 is started, so that clamp 38 drives the support component 3 to move upward and enter the safety component 4.

[0043] refer to Figures 7 to 11 Safety component 4 is used to provide a pressure buffer area to improve the safety of the door panel inspection process of the air defense door. Safety component 4 includes a safety shell 401 and a safety plate 406. The outer wall of the safety shell 401 is fixedly connected to the connecting block 15. A limit hole 407 is opened on the long side shell wall of the safety shell 401. A sealing plate 18 is installed at the bottom of the safety shell 401. A process hole 21 with the same shape as the support component 3 is opened in the middle of the sealing plate 18. The safety plate 406 is symmetrically arranged on both sides of the long side of the process hole 21 through the limit hole 407. A driver 11 is installed on the outer wall near the limit hole 407. The output end of the driver 11 is fixedly connected to the upper end of the safety plate 406 through the limit hole 407.

[0044] Several sets of motors 403 are arranged above the sealing plate 2 18. The output end of the motors 403 faces the sealing plate 2 18. The output end of each motor 403 is connected to a lead screw 402. The other end of each lead screw 402 is connected to a bearing of the sealing plate 2 18. Each lead screw 402 has a ring 405 threadedly connected to its shaft. Each ring 405 is connected to a clamp 404. The clamp 404 includes a hydraulic cylinder installed inside. The output end of the hydraulic cylinder is connected to a gripper.

[0045] The following is a supplementary explanation based on the above structure: During the process of clamp 3 8 driving support component 3 to move upward, since clamp 3 8 clamps the third segment 3043, when the upper end face of the base plate 301 coincides with the upper end face of the sealing plate 2 18, the third segment 3043 is located below the sealing plate 2 18, and the rest of the support component 3 is located above the sealing plate 2 18. At this time, the hydraulic cylinder inside clamp 1 404 is activated, and clamp 1 404 clamps the second segment 3042, thereby realizing the clamping of support component 3 by safety component 4.

[0046] After safety component 4 clamps support component 3, clamp 3 8 releases support component 3. At this time, support component 3 is completely clamped by safety component 4. Motor 2 503 is started. Motor 2 503 drives clamp 1 404 to move. The moving principle is the same as the moving principle of motor 3 9 driving clamp 3 8. Clamp 1 404 drives support component 3 to move upward and enter detection component 5.

[0047] When the third segment 3043 is above the sealing plate 2 18, the driver 11 is activated. The driver 11 pushes the safety plates 406 on both sides to move towards each other, so that the safety plates 406 cover the process hole 21.

[0048] refer to Figures 11 to 15 The detection component 5 is used to test the overall shape, airtightness, and air pressure resistance of the air defense door panel. The detection component 5 includes a detection shell 501, which is positioned above the safety component 4. The lower end of the detection shell 501 is fixedly connected to the upper end of the safety shell 401. When multiple sets of detection components 5 are installed sequentially, the detection shells 501 of each set are fixedly connected to each other. Limiting holes 508 are provided on all four sides of the shell wall of the detection shell 501. A sealing plate 12 is fixedly installed at the bottom of the detection shell 501. A motor 403 is fixedly installed on the lower end face of the sealing plate 12. A light bulb 14 is installed at the bottom of the sealing plate 12. A [missing information - likely a device or feature] is provided in the middle of the sealing plate 12. A long-side baffle 506 and a wide-side baffle 507 are symmetrically arranged above the process hole 13 and the sealing plate 12, respectively. A sealing ring 1 is installed around the long-side baffle 506 and the wide-side baffle 507. The long-side baffle 506 is located above the wide-side baffle 507. The width of the wide-side baffle 507 is the same as the distance between the two sets of baffles 306. The height of the wide-side baffle 507 is the same as the height of the baffle 306. A driver 20 is fixedly installed on the outer wall of the detection shell 501 near the limiting hole 2 508. The driver 20 has the same structure as the driver 11. The output end of the driver 20 passes through the limiting hole 2 508 and is fixedly connected to the upper ends of the long-side baffle 506 and the wide-side baffle 507, respectively.

[0049] A motor 503 is installed on the upper end of the sealing plate 12. The motor 503 is installed on the lower end face of the sealing plate 12 of the upper detection component 5. The output end of the motor 503 faces the sealing plate 12. The output end of the motor 503 is connected to a lead screw 502. A ring 505 is threaded on the shaft of the lead screw 502. The ring 505 is connected to a clamp 504. The clamp 504 includes a hydraulic cylinder installed inside. The output end of the hydraulic cylinder is connected to a gripper.

[0050] The following is a supplementary explanation based on the above structure: During the process of clamp 1 404 driving support component 3 from safety component 4 into detection component 5, since clamp 1 404 clamps the second segment 3042, the first segment 3041 first passes through sealing plate 12 and enters detection component 5. When the first segment 3041 is inside detection component 5, clamp 2 504 clamps the first segment 3041. The clamping principle is the same as the clamping principle of clamp 3 8.

[0051] After clamp 2 504 completes clamping, control clamp 1 404 to release support component 3. Motor 1 403 drives clamp 1 404 to move downward until clamp 1 404 moves to the position of the third segment 3043. Clamp 1 404 clamps the third segment 3043. At this time, clamp 2 504 clamps the first segment 3041 and clamp 1 404 clamps the third segment 3043. Control motor 1 403 and motor 2 503 to work synchronously, so that clamp 1 404 and clamp 2 504 work together to drive support component 3 to move upward. When the second segment 3042 moves into the detection component 5, control motor 1 403 and motor 2 503 to stop working.

[0052] Control clamp 2 504 releases support assembly 3, motor 2 503 drives clamp 2 504 to move to the second segment 3042 position, so that clamp 2 504 clamps the second segment 3042. Control clamp 1 404 releases support assembly 3, clamp 2 504 drives support assembly 3 to move upward and enter the upper layer detection assembly 5. The transportation principle between different layers of detection assembly 5 is the same as the above principle. Finally, the bottom plate 301 and the sealing plate 12 of the uppermost detection assembly 5 are at the same water position. Since the shape of support assembly 3 is the same as process hole 13, at this time the sealing ring 2 of support assembly 3 seals process hole 13, and the gas in detection assembly 5 can only flow through the gap between rollers 305.

[0053] The principle of moving the support component 3 down from the top detection component 5 to reset it is the same as the principle described above, but the operation is reversed.

[0054] Three sets of detection components 5 are provided as an example. The detection shell 501 of each set of detection components 5 is fixedly connected. The detection shell 501 located at the bottom is fixedly installed above the safety shell 401. The outer walls of the safety shell 401 and the detection shell 501 are fixedly connected to the connecting block 15. A top shell 19 is fixedly installed above the detection component 5 located at the top. A light bulb 14 is installed at the lower end of the top shell 19. An air inlet cylinder 16 passes through the outer shell 1 and the top shell 19 and communicates with the interior of the top detection component 5. A compressor 17 is provided on the outside of the outer shell 1. The output end of the compressor 17 is connected to the air inlet cylinder 16 pipeline.

[0055] Under otherwise identical conditions, the inspection steps for the air-raid shelter door panel are as follows:

[0056] Step 1: Transport the door panel to be tested to the top of the support assembly 3 via track 2, start motor 3 9 and motor 1 403 to drive the support assembly 3 into the safety assembly 4;

[0057] Step 2: Start motor 1 (403) and motor 2 (503) to drive the support component 3 into the detection component 5. The detection components 5 work together to make the support component 3 enter the top detection component 5.

[0058] Step 3: Use the top-level detection component 5 to inspect the overall shape and airtightness of the air-raid shelter door panel;

[0059] Step 4: Control the movement of the support component 3 so that the support component 3 is located inside the detection component 5 at different heights, and detect the maximum air pressure that the air defense door panel can withstand.

[0060] Specifically, in step three, the second actuator 20 of the top-level detection component 5 is activated. The second actuator 20 pushes the long side baffle 506 and the wide side baffle 507 towards the door panel of the air-raid shelter until the sealing rings of the long side baffle 506 and the wide side baffle 507 are in contact with the perimeter of the air-raid shelter door panel above the support component 3. The long side baffle 506 and the wide side baffle 507 push the air-raid shelter door panel to adjust its position. Due to the coordinated operation of the second actuator 20, the air-raid shelter door panel is finally positioned... At the middle position of the support component 3, the position of the door panels of different specifications of the air defense door is adjusted by using the long side baffle 506 and the wide side baffle 507. At this time, the wide side baffle 507 covers the rollers 305 on both sides of the air defense door panel, and the long side baffle 506 covers the rollers 305 on both sides of the long side of the air defense door panel. The light sensor 302 is blocked. The sealing rings of the long side baffle 506 and the wide side baffle 507 are in contact with the surface of the air defense door panel, sealing the air defense door panel around its perimeter.

[0061] Furthermore, the compressor 17 delivers a rated amount of high-pressure gas through the air inlet cylinder 16 into the detection component 5 and powers the bulb 14 located below the top shell 19, so that the light shines on the surface of the air defense door panel. If the air pressure sensor 303 detects that the air pressure inside the detection component 5 rises to a certain value and then stops rising, with the highest value being the air pressure inside the detection component 5 of the rated amount of high-pressure gas, which is recorded as the rated air pressure, and the light sensor 302 cannot receive the light signal, it indicates that the long side baffle 506 and the wide side baffle 507 are completely fitted to the four sides of the air defense door panel to be tested, which means that the overall shape of the air defense door panel is qualified and the airtightness is good.

[0062] Based on the above detection method, and according to the changes in the optical sensor 302 and the barometric pressure sensor 303, the following analytical results can also be obtained:

[0063] Scenario 1: If the air pressure sensor 303 detects that the air pressure rises to a certain value and then stops rising, but the maximum detected air pressure value is less than the rated air pressure, after the compressor 17 finishes delivering, the air pressure sensor 303 detects that the air pressure gradually decreases. At the same time, the light sensor 302 receives a light signal, indicating that there is a defect in the structure of the tested air defense door panel, which makes the sealing ring 1 unable to fit the perimeter of the door panel. There is a gap between the air defense door panel and the long side baffle 506 and the wide side baffle 507, causing gas to leak through the gap. Light shines through the gap onto the light sensor 302.

[0064] Furthermore, if the light signal received by the light sensor 302 is irregularly distributed in the form of dots, it indicates that there are concave or convex areas in the outline of the air defense door panel, resulting in tiny holes between the outline of the air defense door panel and the long side baffle 506 and the wide side baffle 507, allowing light to shine onto the surface of the light sensor 302. The shape defects caused by small-scale concave or convex areas can be corrected through subsequent repair operations.

[0065] Furthermore, if the light signal received by the light sensor 302 appears as one or more continuous strips, it indicates that one or more sides of the air-raid shelter door panel were tilted during manufacturing, resulting in a continuous gap between the tilted side and the long side baffle 506 and the wide side baffle 507, causing light to shine onto the surface of the light sensor 302. The presence of tilt on one or more sides indicates a problem with the manufacturing process of the air-raid shelter door panel. Production should be stopped, the cause of the problem investigated, and the air-raid shelter door panels that fail the test should be scrapped.

[0066] Scenario 2: If the light sensor 302 does not detect the light signal, but the air pressure sensor 303 detects that the air pressure rises to a certain value and then stops rising, but the maximum detected air pressure value is less than the rated air pressure, and the air pressure sensor 303 detects that the air pressure gradually decreases after the compressor 17 finishes delivering, it indicates that the overall shape of the air defense door panel itself is qualified, but there are tiny gaps in the structure of the air defense door panel itself, which allow gas to leak through the gaps.

[0067] Furthermore, multiple sets of air-raid shelter door panels should be inspected to confirm the frequency of structural gaps in the door panels. If the gaps are within the error range, the defective products should be scrapped separately. If the gaps are greater than the error range, it indicates that there is a problem with the manufacturing process of the air-raid shelter door panels themselves, and the cause should be investigated in a timely manner.

[0068] Specifically, in step four, based on step three, after confirming that the overall shape and airtightness of the tested air-raid shelter door panel are qualified, the compressor 17 delivers a rated amount of high-pressure gas into the testing component 5 in batches, causing the internal air pressure of the testing component 5 to increase. If the air-raid shelter door panel deforms under high pressure, specifically manifested as deformation on the side subjected to high pressure, when the air-raid shelter door panel deforms, the deformation inevitably causes gaps between the air-raid shelter door panel and the long side baffle 506 and the wide side baffle 507, causing gas leakage. The air pressure sensor 303 clearly detects the decrease in air pressure and records the maximum air pressure before the pressure drop, denoted as . , This refers to the maximum air pressure that a single side of a civil defense door panel can withstand.

[0069] Furthermore, due to the small internal volume of a single detection component 5, the pressure of the high-pressure gas quickly reaches [the required level]. This causes the door panel of the air-raid shelter to deform rapidly in a short period of time, making it difficult to determine the maximum pressure that the elastic and plastic deformation of the door panel can withstand. Therefore, a brand new door panel should be replaced before proceeding to the next step of testing.

[0070] Furthermore, the control support component 3 moves the door panel of the air-raid shelter downwards to the interior of the detection component 5 in the middle position, so that the bottom plate 301 and the sealing plate 12 of the middle detection component 5 are at the same horizontal height, and the door panel of the air-raid shelter is located in the middle position of the space enclosed by the safety component 4 and several sets of detection components 5. The space enclosed by the safety component 4 and several sets of detection components 5 is called the detection space. The compressor 17 is started to deliver high-pressure gas, which increases the air pressure in the entire detection space. At this time, the entire door panel of the air-raid shelter is subjected to air pressure. Under the comprehensive air pressure, the door panel of the air-raid shelter collapses, which is manifested as irregular cracks or fractures on the overall structure of the door panel of the air-raid shelter. By the distribution of cracks or fracture points, the structural weak points of the door panel of the air-raid shelter can be obtained, which provides a reference for the structural design of the door panel of the air-raid shelter.

[0071] Furthermore, the control support component 3 moves the new air defense door panel downwards to the bottommost detection component 5, so that the bottom plate 301 and the sealing plate 12 of the detection component 5 below are at the same level. At this time, the sealing ring 2 of the support component 3 fits with the sealing plate 12, completing the seal. Then, the long side baffle 506 and the wide side baffle 507 are controlled to fit with the surface of the air defense door panel. At this time, the space volume above the air defense door panel is the sum of the volumes of the three detection components 5. Under the condition that the amount of high-pressure gas introduced by the compressor 17 is the same, the larger space volume causes the pressure of the rated amount of high-pressure gas to drop. In order to make the pressure reach the critical volume of leakage of the air defense door panel, the same amount of high-pressure gas needs to be delivered multiple times. During this process, the pressure rise rate decreases. The slower pressure rise rate reduces the deformation rate of the air defense door panel caused by the pressure. It can more accurately obtain the pressure value that the air defense door panel can withstand when elastic deformation and plastic deformation occur, providing a basis for the selection of materials for the production of air defense door panels.

[0072] Specifically, the slowly rising air pressure causes the deformation rate of the air-raid shelter door panel to be slow. When deformation leads to the appearance of a gas leakage gap, the gas leakage rate is less than the delivery rate of the compressor 17 because the gap is small. This causes the air pressure sensor 303 to detect a further decrease in the rate of air pressure increase, and the air pressure before the decrease is recorded as... At this point, compressor 17 stops supplying gas. After the gas supply stops, gas continues to leak, causing the gas pressure to gradually decrease. As the gas pressure gradually decreases, if the gas pressure sensor 303 detects that the gas pressure drops to a certain value and then stops changing, it indicates that the deformation of the air defense door panel has gradually returned to its original position, allowing the space to return to a sealed state. This refers to the maximum air pressure that the plastic deformation of the door panel of a civil defense door can withstand.

[0073] Furthermore, by intermittently supplying gas to the compressor 17, the relative movement of the safety plate 406 inside the safety component 4 is controlled, causing the process hole 13 of the sealing plate 18 to open, so as to discharge the leaked gas to the external environment and prevent the gas pressure of the leaked gas from affecting the test results.

[0074] As the compressor 17 intermittently delivers gas, the deformation of the air defense door panel increases continuously, causing gas leakage to increase continuously. When the compressor 17 stops delivering gas, if the gas pressure at this time has not reached the critical gas pressure for plastic deformation, the gas pressure sensor 303 detects that the gas pressure drops to a certain value and remains stationary, indicating that the deformation of the air defense door panel has been reset, and the leaked gas pressure directly enters the outside through the process hole 13.

[0075] Since the process hole 13 of the sealing plate 2 18 is open, the leaked gas continuously enters the outside. Therefore, when the air pressure sensor 303 detects that the air pressure gradually decreases until it is the same as the outside atmospheric pressure, it indicates that the deformation of the door panel of the air defense door has been reset. Therefore, the air pressure sensor 303 detects that the air pressure before the air pressure decreases is the maximum air pressure that plastic deformation can withstand.

[0076] By comparing and analyzing the maximum air pressure that the elastic deformation and plastic deformation of different materials of civil defense door panels can withstand, it has a positive effect on the selection of materials for the production of civil defense door panels.
