Description

Technical Field

[0001] The present invention belongs to the technical field of airtightness detection of steel-plastic pipes, and specifically relates to a detection device for the production of steel-plastic pipe fittings based on intelligent sensing. Background Art

[0002] Steel-plastic pipe fittings are pipe connectors made of composite materials of steel and plastic materials, which have the characteristics of corrosion resistance, pressure resistance, long service life, and convenient installation. They are widely used in many fields such as construction, municipal engineering, petroleum, and chemical industry. They have the advantages of corrosion resistance, pressure resistance, long service life, and convenient installation. The airtightness detection of steel-plastic pipe fittings is an important link to ensure their quality and performance. The main purpose of airtightness detection is to check whether there is leakage in the steel-plastic pipe fittings to ensure that they can maintain the sealing performance during use, prevent medium leakage and environmental pollution. There are various methods for airtightness detection of steel-plastic pipe fittings, and common ones include the water immersion method, the pressure drop method, the differential pressure method, the direct pressure method, and the mass flow method, etc.

[0003] Chinese invention patent CN110220653A discloses a double-wall pipe airtightness detection tooling and detection method. The detection tooling includes a blanking cover, a test cover plate, a cover plate, a water inlet pipe group, a water outlet pipe group, and an air inlet pipe. The blanking cover plugs the natural gas inlet of the double-wall pipe, and the test cover plate and the cover plate respectively seal both ends of the double-wall pipe; one end of the water inlet pipe group and one end of the water outlet pipe group are respectively connected to the test cover plate; the detection accuracy of this airtightness detection tooling is low, and the detection effect is poor.

[0004] Chinese invention patent CN115371903A discloses a heat energy pipe airtightness detection device, specifically related to the technical field of production detection of heat energy equipment, including a housing. A window is provided on the front side of the housing, a comparison plate is provided on the rear side inside the housing, openings are provided at both ends of the housing, a fixed ring is fixedly provided inside one of the openings, and a sealed smoke inlet mechanism is provided at one end of the housing; the operation difficulty of this airtightness detection device is high, and the detection efficiency is low.

[0005] When actually detecting the airtightness of steel-plastic pipe fittings, if there are dust impurities, etc. on the inner wall of the steel-plastic pipe fittings, it will affect the subsequent sealing performance of the steel-plastic pipe fittings and ultimately reduce the accuracy of airtightness detection.

[0006] And because the diameters and lengths of steel-plastic pipe fittings are different, and when clamping and fixing the steel-plastic pipe fittings, the steel-plastic pipe fittings have their own gravity and are prone to deviation, which will cause the steel-plastic pipe fittings to deviate and cannot be coaxially clamped and sealed, ultimately directly affecting the airtightness detection of the steel-plastic pipe fittings.

[0007] At the same time, the existing steel-plastic pipe fitting detection equipment can only detect that there are cracks in the steel-plastic pipe fittings, but cannot accurately determine the position and size of the cracks, which increases the difficulty of subsequent crack treatment of the steel-plastic pipe fittings.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] As Figures 1-11 shown, a detection device for the production of steel-plastic pipe fittings based on intelligent sensing. During the key production and processing of steel-plastic pipe fittings, the airtightness of the steel-plastic pipe fittings is the main detection item, which is directly related to the quality of the steel-plastic pipe fittings. Therefore, the detection device for the production of steel-plastic pipe fittings in this application mainly includes a housing assembly 1. An adjustment assembly 2 is provided inside the housing assembly 1. The adjustment assembly 2 mainly adjusts the positions of the positioning assembly 3 and the detection assembly 4. A plurality of positioning assemblies 3 are evenly arranged on one side above the adjustment assembly 2. The positioning assembly 3 positions and installs a plurality of steel-plastic pipe fittings to improve the detection accuracy. A plurality of detection assemblies 4 are evenly arranged on the other side above the adjustment assembly 2. After the steel-plastic pipe fittings are installed, the detection assembly 4 performs subsequent precise detection.

[0042] The housing assembly 1 includes a housing 101. Inside the housing 101, there is a detection chamber 102. Inside the detection chamber 102, there is a detection liquid, which is mostly clear water. During actual detection, high-pressure gas is filled inside the steel-plastic pipe fitting, and then the steel-plastic pipe fitting is placed in the clear water inside the detection chamber 102. If there are cracks inside the steel-plastic pipe fitting, the high-pressure gas inside the steel-plastic pipe fitting will discharge along the crack position, and then form bubbles inside the detection chamber 102, which is convenient for quickly observing the airtightness of the steel-plastic pipe fitting. Above the housing 101, there is a transfer box 109. The setting of the transfer box 109 facilitates the regulation of the detection process and the storage and transfer of gas.

[0043] At the top of one side of the housing 101, there is a support frame 104. At the top of the support frame 104, there is a top plate 105. The support frame 104 and the top plate 105 wrap and protect the internal detection chamber 102. The top of the transfer box 109 is fixedly connected to the bottom of the top plate 105. On one side of the top of the top plate 105, there is an air pump 106. At the bottom of the air pump 106, there are a plurality of bases 107 evenly arranged. The bottom of the base 107 is fixedly connected to the top of the top plate 105. The setting of the base 107 improves the safety and stability of the air pump 106. The output end of the air pump 106 is provided with an air inlet pipe 108. The other end of the air inlet pipe 108 passes through the top plate 105 and is connected to the transfer box 109 in communication. When the air pump 106 is started and high-pressure gas is introduced into the air inlet pipe 108, the high-pressure gas enters the transfer box 109 for transfer and storage. At the bottom of the housing 101, there are a plurality of feet 103 threadedly connected evenly. The setting of the feet 103 improves the stability of the housing 101. In the middle of one side of the transfer box 109, there is a control screen 110, which can control the detection device. On one side of the transfer box 109 and on both sides of the control screen 110, there are a plurality of buttons 111 evenly arranged. Each button 111 corresponds to controlling different processes. At the bottom of the transfer box 109, there is a tripod 112. The bottom of the tripod 112 is fixedly connected to the top of the housing 101. The tripod 112 supports and fixes the transfer box 109.

[0044] The adjustment assembly 2 includes a moving plate 212, which can move up and down inside the detection chamber 102, and then drive the positioning assembly 3, the detection assembly 4 and the steel-plastic pipe fitting to move for airtightness detection. At the bottom of the moving plate 212, there are a plurality of connecting plates 211 evenly arranged. Inside the detection chamber 102 and below the transfer box 109, there are two groups of side frames 201 symmetrically arranged. Between the two groups of side frames 201, there are a plurality of splicing rods 202 evenly arranged. The setting of the splicing rods 202 improves the support and connection of the two groups of side frames 201. On one side of the side frame 201, there are a plurality of limit grooves 203 evenly arranged. Inside the limit groove 203, there is a limit block 204 in sealed sliding connection. The side wall of the limit block 204 is fixedly connected to the side wall of the connecting plate 211. The limit block 204 and the limit groove 203 are in sealed sliding connection with each other, further improving the movement stability and synchronization of the plurality of connecting plates 211.

[0045] On one side of the side frame 201 away from the limit groove 203, there is a fixed block 205. At the bottom of the fixed block 205, there is a slide rail 207. On both sides of the bottom of the fixed block 205, there are inclined support rods 206. The other end of the inclined support rod 206 is fixedly connected to the inner bottom of the detection cavity 102. The inclined support rod 206 improves the stability and support of the fixed block 205. On one side of the slide rail 207 close to the moving plate 212, a plurality of chutes 208 are evenly opened. Inside the chute 208, there is a sliding block 209 in sealed sliding connection. The side wall of the sliding block 209 is fixedly connected to the side wall of the connecting plate 211. The sliding block 209 moves up and down inside the chute 208. The sliding block 209 synchronously drives the moving plate 212 to move up and down through the connecting plate 211. The moving plate 212 drives the positioning component 3, the detection component 4 and the steel-plastic pipe fitting to move, further improving the airtightness detection efficiency. At the bottom of the sliding block 209, there is a moving hydraulic rod 210. The bottom of the moving hydraulic rod 210 is fixedly connected to the inner bottom of the detection cavity 102. The output end of the moving hydraulic rod 210 can drive the sliding block 209 to move up and down.

[0046] The positioning component 3 includes a positioning exhaust cylinder 304. On the outer surface of the positioning exhaust cylinder 304, there is an elastic sealing ring 307. The elastic sealing ring 307 has elasticity. Therefore, by means of the elastic sealing ring 307 fitting with the inner wall of the steel-plastic pipe fitting, the tightness of the detection is ensured. On one side of the elastic sealing ring 307, a plurality of adjusting pneumatic rods 308 are evenly arranged. After the adjusting pneumatic rod 308 is started, its output end extends to squeeze the elastic sealing ring 307. The elastic sealing ring 307 undergoes elastic deformation and fits and seals with the inner wall of the steel-plastic pipe fitting.

[0047] The positioning component 3 further includes a positioning fixing plate 301. The bottom of the positioning fixing plate 301 is fixedly connected to one side of the top of the moving plate 212, and a plurality of positioning fixing plates 301 are evenly distributed on the top of the connecting plate 211. Inside the positioning fixing plate 301, there is a positioning through hole 303. On one side of the positioning fixing plate 301 away from the detection exhaust cylinder 404, there is a positioning pneumatic rod 302. The output end of the positioning pneumatic rod 302 passes through the positioning through hole 303 and is fixedly connected to the side wall of the positioning exhaust cylinder 304. After the positioning pneumatic rod 302 is started, its output end drives the positioning exhaust cylinder 304 to move above the connecting plate 211, thereby realizing the clamping and fixing of the steel-plastic pipe fitting by the positioning exhaust cylinder 304. The inside of the positioning exhaust cylinder 304 is communicated with a positioning air outlet pipe 305. The other end of the positioning air outlet pipe 305 is communicated with the inside of the transfer box 109. The high-pressure gas inside the transfer box 109 enters the inside of the positioning exhaust cylinder 304 along the positioning air outlet pipe 305 and enters the inside of the steel-plastic pipe fitting along the positioning exhaust cylinder 304 for filling, thereby realizing the airtightness detection process of the steel-plastic pipe fitting.

[0048] The outer surface of the positioning exhaust pipe 304 is provided with a support ring 306. The side wall of the support ring 306 is in extrusion contact with the side wall of the elastic sealing ring 307. The diameter value of the support ring 306 is greater than that of the elastic sealing ring 307. Therefore, the support ring 306 can not only limit and fix the side wall of the elastic sealing ring 307, but also block the side wall of the steel-plastic pipe fitting, avoiding the sliding of the steel-plastic pipe fitting above the connecting plate 211 and reducing the detection accuracy. At the same time, it can also improve the positioning accuracy of the steel-plastic pipe fitting. On the outer surface of the positioning exhaust pipe 304 close to the detection exhaust pipe 404, there is an installation ring 309. The side wall of the installation ring 309 is fixedly connected to the side walls of a plurality of adjusting pneumatic rods 308. The other output ends of the adjusting pneumatic rods 308 are in extrusion contact with the side wall of the elastic sealing ring 307. When it is necessary to seal the inner wall of the steel-plastic pipe fitting, the plurality of adjusting pneumatic rods 308 are started and the output ends extend. The output ends of the adjusting pneumatic rods 308 extrude and deform the elastic sealing ring 307, thereby realizing the fitting and sealing of the elastic sealing ring 307 with the inner wall of the steel-plastic pipe fitting.

[0049] The detection assembly 4 includes a detection exhaust pipe 404, which cleans and detects the inside of the steel-plastic pipe fitting. The detection assembly 4 also includes a detection fixing plate 401. The bottom of the detection fixing plate 401 is fixedly connected to the other side of the top of the moving plate 212. A plurality of detection fixing plates 401 are evenly distributed on the top of the connecting plate 211. A detection through hole 403 is provided inside the detection fixing plate 401. On the side of the detection fixing plate 401 away from the positioning exhaust pipe 304, there is a clamping pneumatic rod 402. The output end of the clamping pneumatic rod 402 passes through the detection through hole 403 and is fixedly connected to the side wall of the detection exhaust pipe 404. When the clamping pneumatic rod 402 is started and the output end drives the detection exhaust pipe 404 to move, it can cooperate with the positioning pneumatic rod 302 to realize the clamping and positioning of steel-plastic pipe fittings with different lengths and the airtightness detection. The inside of the detection exhaust pipe 404 is communicated with a detection air outlet pipe 405. The other end of the detection air outlet pipe 405 is communicated with the inside of the transfer box 109. The high-pressure gas inside the transfer box 109 can also be discharged into the detection exhaust pipe 404 along the detection air outlet pipe 405, thereby improving the cleaning and positioning and sealing effects on the inner wall of the steel-plastic pipe fitting.

[0050] On one side of the detection exhaust pipe 404, there is a sliding connection with an inner moving block 407. The inner moving block 407 can move inside the steel-plastic pipe fitting, thereby achieving precise positioning of the crack position of the steel-plastic pipe fitting. On the outer surface of the detection exhaust pipe 404, there is a stop ring 406. The stop ring 406 is in mutual extrusion contact with the side wall of the inner moving block 407. The stop ring 406 not only calibrates the initial position of the inner moving block 407 but also locates and blocks the side wall of the steel-plastic pipe fitting, improving the positioning accuracy of the steel-plastic pipe fitting. On the side of the inner moving block 407 close to the detection exhaust pipe 404, there is a docking groove 424. The inner wall of the docking groove 424 matches the outer surface of the detection exhaust pipe 404. The setting of the docking groove 424 prevents the inner moving block 407 from blocking the air outlet end of the detection exhaust pipe 404, thereby ensuring the continuous and stable exhaust of the detection exhaust pipe 404. On the side wall of the detection exhaust pipe 404, there is a return spring 412. The other end of the return spring 412 is fixedly connected to the inner wall of the docking groove 424. The setting of the return spring 412 realizes the elastic reset performance of the inner moving block 407.

[0051] On the circumferential side surface of the inner moving block 407, there is a ring groove 408. Inside the ring groove 408, there is an elastic support ring bladder 409. When the inner wall of the elastic support ring bladder 409 is squeezed, it can make sealing contact with the inner wall of the steel-plastic pipe fitting, improving the sealing performance of the steel-plastic pipe fitting. Inside the inner moving block 407, there are evenly arranged a plurality of lateral holes 413. Inside the inner moving block 407, there are evenly arranged a plurality of matching holes 417. Inside the matching hole 417, there is a sealing sliding connection with a gas-blocking rod 418. The gas-blocking rod 418 can slide hermetically inside the matching hole 417. One end of the lateral holes 413 facing each other is vertically connected to the matching hole 417. One end of the lateral holes 413 facing away from each other is connected to the annular surface of the ring groove 408. High-pressure gas discharged along the detection exhaust pipe 404 can flow inside the lateral holes 413. The gas-blocking rod 418 matches the lateral holes 413. When the position of the gas-blocking rod 418 moving inside the matching hole 417 is different, the blocking area of the gas-blocking rod 418 for the lateral holes 413 is different, and the amount of high-pressure gas introduced into the lateral holes 413 is different. On the inner wall of the lateral holes 413, there is a retaining ring 414. On one side of the retaining ring 414, there is a connecting spring 415. At the other end of the connecting spring 415, there is a push block 416. The setting of the connecting spring 415 improves the elastic reset performance of the push block 416 inside the lateral holes 413.

[0052] The other end of the pushing block 416 is in mutual extrusion contact with the inner wall of the elastic support ring capsule 409. When the amount of high-pressure gas introduced into the lateral hole 413 increases, the high-pressure gas drives the pushing block 416 to increase the supporting force on the side wall of the elastic support ring capsule 409, and the extrusion force between the other side of the elastic support ring capsule 409 and the inside of the steel-plastic pipe fitting increases, further improving the sealing performance of the steel-plastic pipe fitting. There is magnetic powder inside the elastic support ring capsule 409. A plurality of discharge holes 410 are evenly opened on the side of the elastic support ring capsule 409 away from the inner moving block 407. An electromagnetic valve 411 is provided inside the discharge holes 410. The discharge holes 410 are matched with the positions of the lateral holes 413. When cracks appear in the steel-plastic pipe fitting, the electromagnetic valve 411 is opened, and the magnetic powder inside the elastic support ring capsule 409 is discharged along the discharge holes 410 and marks the crack position, thereby improving the accuracy of subsequent repair of the cracks in the steel-plastic pipe fitting.

[0053] One end of the air-blocking rod 418 is provided with a magnetic blocking block 422. A plurality of grooves 419 are evenly opened on the side of the inner moving block 407 away from the detection exhaust cylinder 404. An electromagnetic ring 420 is provided on the inner wall of the grooves 419. The other end of the electromagnetic ring 420 is provided with a support spring 421. The other end of the support spring 421 is fixedly connected to the side wall of the magnetic blocking block 422. The setting of the support spring 421 further improves the elastic reset performance of the magnetic blocking block 422. The support spring 421 is located on the outer surface of the air-blocking rod 418. The end faces of the electromagnetic ring 420 and the magnetic blocking block 422 facing each other have the same magnetism. When the energizing current of the electromagnetic ring 420 increases, the magnetic repulsion force of the electromagnetic ring 420 on the magnetic blocking block 422 increases, and the magnetic blocking block 422 stretches the support spring 421 and moves away from the electromagnetic ring 420 end. The magnetic blocking block 422 synchronously drives the air-blocking rod 418 to move. The other end of the magnetic blocking block 422 is provided with a pressure sensor 423, and the pressure sensor 423 is used to detect the air pressure value at the end of the magnetic blocking block 422.

[0054] When actually detecting the airtightness of the steel-plastic pipe fitting, if there are dust impurities, etc. on the inner wall of the steel-plastic pipe fitting, it will affect the subsequent sealing of the steel-plastic pipe fitting and ultimately reduce the accuracy of the airtightness detection; and because the diameters and lengths of the steel-plastic pipe fittings are different, and when clamping and fixing the steel-plastic pipe fitting, the steel-plastic pipe fitting itself has gravity and is prone to offset, which will cause the steel-plastic pipe fitting to offset and cannot be coaxially clamped and sealed, directly affecting the airtightness detection of the steel-plastic pipe fitting; at the same time, the existing steel-plastic pipe fitting detection equipment can only detect that there are cracks in the steel-plastic pipe fitting, but cannot accurately determine the position and size of the cracks, which increases the difficulty of subsequent crack treatment of the steel-plastic pipe fitting.

[0055] To solve the above problems, when the detection device for the production of steel-plastic pipe fittings based on intelligent sensing is actually used, the air pump 106 starts and injects high-pressure gas into the inside of the transfer box 109 along the air inlet pipe 108 for temporary storage. The connecting plate 211 drives the positioning assembly 3 and the detection assembly 4 to the initial position. Then, multiple steel-plastic pipe fittings are transferred above the connecting plate 211 and correspond to multiple positioning exhaust cylinders 304 and detection exhaust cylinders 404 in sequence. At this time, the steel-plastic pipe fittings are inserted into the outer surface of the positioning exhaust cylinder 304 and are in mutual extrusion contact with the side wall of the support ring 306. At the same time, the clamping pneumatic rod 402 starts and the output end extends. The output end of the clamping pneumatic rod 402 drives the detection exhaust cylinder 404 to move towards the positioning exhaust cylinder 304 until it reaches the inside of the steel-plastic pipe fitting, thus completing the assembly of the steel-plastic pipe fitting. Under the action of the gravity of the steel-plastic pipe fitting, it is in mutual extrusion contact with the elastic sealing ring 307 and the top of the elastic support ring bladder 409.

[0056] Then the control screen 110 controls the energizing current of the electromagnetic ring 420 to reach the maximum. The electromagnetic ring 420 exerts a magnetic repulsive force on the magnetic block 422 and drives the magnetic block 422 to stretch the support spring 421 and move away from the detection exhaust cylinder 404. The magnetic block 422 drives the air-blocking rod 418 to move synchronously. When the air-blocking rod 418 disengages from the matching hole 417, the groove 419 communicates with the matching hole 417. The high-pressure gas inside the transfer box 109 enters the inside of the detection exhaust cylinder 404 along the detection outlet pipe 405, and then enters the docking groove 424 along the detection exhaust cylinder 404. The high-pressure gas inside the docking groove 424 further enters the groove 419 along multiple matching holes 417 and finally is discharged into the steel-plastic pipe fitting along the groove 419. At this time, since the elastic sealing ring 307 and the elastic support ring bladder 409 do not seal and fit the inner wall of the steel-plastic pipe fitting, the high-pressure gas can flow along the steel-plastic pipe fitting to both sides and is finally discharged along both sides of the steel-plastic pipe fitting, further realizing the wind cleaning effect on the inner wall of the steel-plastic pipe fitting, avoiding the influence of dust and impurities attached to the inner wall of the steel-plastic pipe fitting on the subsequent airtightness detection. At the same time, to ensure the thoroughness of the cleaning of the inner wall of the steel-plastic pipe fitting, the steel-plastic pipe fitting can be rotated during actual use. Then, under the action of the gravity of the steel-plastic pipe fitting, the elastic sealing ring 307 and the elastic support ring bladder 409 are always in mutual extrusion contact with the inner top of the steel-plastic pipe fitting, thereby continuously changing the contact position with the rotation of the steel-plastic pipe fitting, and further improving the thoroughness and stability of the cleaning of the inner wall of the steel-plastic pipe fitting.

[0057] After the inner wall of the steel-plastic pipe fitting is cleaned, the control panel 110 controls the energizing current of the electromagnetic ring 420 to decrease to the initial value. Then, the magnetic repulsive force of the electromagnetic ring 420 on the magnetic block 422 decreases. Under the elastic force of the support spring 421, the magnetic block 422 is driven to be in the initial position. The magnetic block 422 drives the air-blocking rod 418 to move reversely along the matching hole 417 to the initial position. The air-blocking rod 418 blocks part of the lateral holes 413. The high-pressure gas inside the docking groove 424 enters the inside of the lateral holes 413 along the matching hole 417 and applies a force to the push block 416. The push block 416 stretches the connecting spring 415 and moves away from the air-blocking rod 418. The force applied by the push block 416 to the elastic support ring bladder 409 increases. Correspondingly, the elastic support ring bladder 409 continuously moves along the annular groove 408. The elastic support ring bladder 409 is hermetically squeezed and fitted with the inner wall of the steel-plastic pipe fitting. At the same time, the control panel 110 controls a plurality of adjusting pneumatic rods 308 to start and the output ends extend. The adjusting pneumatic rods 308 apply a squeezing force to one side of the elastic sealing ring 307. The other side of the elastic sealing ring 307 is limited by the support ring 306 and continuously collides. Then, the outer surface of the elastic sealing ring 307 is also hermetically squeezed and fitted with the inner wall of the steel-plastic pipe fitting, thereby completing the fixed installation process of the steel-plastic pipe fitting.

[0058] After that, the control panel 110 controls the high-pressure gas inside the transfer box 109 to no longer enter the inside of the detection exhaust cylinder 404 along the detection air outlet pipe 405. The air pressure entering the docking groove 424 inside the detection exhaust cylinder 404 is stable. The high-pressure gas inside the transfer box 109 enters the inside of the positioning exhaust cylinder 304 along the positioning air outlet pipe 305. The high-pressure gas inside the positioning exhaust cylinder 304 continuously enters the inner cavity of the steel-plastic pipe fitting. The high-pressure gas in the inner cavity of the steel-plastic pipe fitting continuously moves to the other end and reaches the end of the inner moving block 407. The air pressure values detected by a plurality of air pressure sensors 423 continuously increase. When the air pressure values detected by a plurality of air pressure sensors 423 are equal, it indicates that the steel-plastic pipe fitting is coaxially placed with the positioning exhaust cylinder 304 and the detection exhaust cylinder 404, and the elastic sealing ring 307 and the elastic support ring bladder 409 are hermetically fitted with the inner wall of the steel-plastic pipe fitting.

[0059] If the air pressure value detected by a certain side air pressure sensor 423 decreases, it indicates that the high-pressure gas inside the steel-plastic pipe fitting leaks at this position, that is, the elastic support ring bladder 409 at this position is not hermetically fitted with the inner wall of the steel-plastic pipe fitting. Commonly, it is the plurality of air pressure sensors 423 below the inner moving block 407. Because the steel-plastic pipe fitting itself has gravity and is different, the squeezing force applied by the top of the inner cavity of the steel-plastic pipe fitting to the tops of the elastic support ring bladder 409 and the elastic sealing ring 307 is large, which may cause the situation that the steel-plastic pipe fitting is not coaxial with the positioning exhaust cylinder 304 and the detection exhaust cylinder 404. At this time, it is necessary to increase the supporting force of the tops of the elastic support ring bladder 409 and the elastic sealing ring 307 on the top of the inner cavity of the steel-plastic pipe fitting.

[0060] That is, if the air pressure value detected by the air pressure sensor 423 at a certain position below decreases, the control panel 110 controls the current passing through the electromagnetic ring 420 at the corresponding position above to increase. The magnetic repulsion force of the electromagnetic ring 420 on the magnetic block 422 increases, and the magnetic block 422 stretches the support spring 421 and moves a greater distance away from the detection exhaust pipe 404 end along the matching hole 417. The magnetic block 422 synchronously drives the air blocking rod 418 to move, and the blocking area of the air blocking rod 418 on the side hole 413 decreases. At the same time, the amount of high-pressure gas inside the docking groove 424 increases, and the amount of high-pressure gas inside the docking groove 424 entering the side hole 413 along the matching hole 417 increases. The amount of high-pressure gas inside the side hole 413 increases and the thrust applied to one side of the push block 416 increases. The extrusion force applied by the other side of the push block 416 to the side wall of the elastic support ring bladder 409 increases, and the elastic support ring bladder 409 moves a greater distance along the ring groove 408, further improving the degree of fitting between the elastic support ring bladder 409 and the inner wall of the steel-plastic pipe at this position, thereby improving the sealing effect of the elastic support ring bladder 409 on the inner wall of the steel-plastic pipe.

[0061] At the same time, the control panel 110 controls the adjustment pneumatic rod 308 at the position corresponding to the electromagnetic ring 420 to start and the output end extends. The extrusion force applied by the output end of the adjustment pneumatic rod 308 to the elastic sealing ring 307 increases, and the elastic sealing ring 307 elastically expands correspondingly at this position and the thrust applied to the inner top of the steel-plastic pipe increases. Then, with the combined action of the elastic support ring bladder 409, the steel-plastic pipe is continuously moved upward to a suitable position, thereby ensuring the coaxial setting of the steel-plastic pipe with the positioning exhaust pipe 304 and the detection exhaust pipe 404, and correspondingly improving the subsequent detection accuracy of the air tightness of the steel-plastic pipe.

[0062] After that, the air tightness of the inner wall of the steel-plastic pipe can be detected. That is, the control panel 110 controls the moving hydraulic rod 210 to start and the output end shortens. The output end of the moving hydraulic rod 210 drives the slider 209 to move downward along the sliding groove 208. The slider 209 drives the connecting plate 211 to move downward. The connecting plate 211 drives the moving plate 212 to move downward. The moving plate 212 drives a plurality of positioning exhaust pipes 304, detection exhaust pipes 404, and the steel-plastic pipe between them to move downward into the detection cavity 102. The steel-plastic pipe is immersed in the clear water inside the detection cavity 102. At this time, since high-pressure gas is filled into the steel-plastic pipe along the positioning exhaust pipe 304, if there are large cracks inside the steel-plastic pipe, the high-pressure gas can directly discharge along the cracks and generate bubbles inside the clear water. The position of the cracks can be determined by means of these bubbles, so as to carry out subsequent processes.

[0063] However, if the operator only relies on the naked eye to observe that there are no bubbles inside the clean water, it is necessary to conduct more accurate inspection of the steel-plastic pipe fittings. Since the steel-plastic pipe fittings are filled with high-pressure gas, if the air pressure values ​​detected by multiple air pressure sensors 423 do not change within a period of time, it means that there is no leakage in the steel-plastic pipe fittings, and the air tightness of the steel-plastic pipe fittings meets the requirements. If the air pressure values ​​detected by multiple air pressure sensors 423 continue to decrease and are less than the set air pressure preset value, it means that there is a leakage in the steel-plastic pipe fittings, and the crack position of the steel-plastic pipe fittings needs to be marked.

[0064] Therefore, the control panel 110 controls the transfer box 109 to increase the amount of high-pressure gas introduced into the detection exhaust cylinder 404 along the detection exhaust pipe 405, and the amount of high-pressure gas entering the docking groove 424 of the detection exhaust cylinder 404 increases and the thrust applied to the inner moving block 407 increases. The inner moving block 407 stretches the reset spring 412 and continuously moves along the inner wall of the steel-plastic pipe away from the end of the detection exhaust cylinder 404. The inner moving block 407 drives the elastic support ring bag 409 on the surrounding side to move synchronously. At this time, the elastic support ring bag 409 and the inner wall of the steel-plastic pipe are still in a fitted and sealed state.

[0065] During the movement, if the air pressure values ​​detected by the multiple air pressure sensors 423 remain unchanged, it means that there is no crack in the steel-plastic pipe at this position. As the inner moving block 407 moves, the contact position between the elastic support ring capsule 409 and the inner wall of the steel-plastic pipe keeps changing, and the support point position of the elastic support ring capsule 409 on the steel-plastic pipe keeps changing. From the principle of lever, it can be seen that the steel-plastic pipe keeps tilting downward under the action of gravity at the end of the detection exhaust pipe 404, and the squeezing force applied by the steel-plastic pipe to the top of the elastic support ring capsule 409 increases. From the above, it can be seen that the high-pressure gas inside the steel-plastic pipe flows along the bottom of the elastic support ring capsule 409. When the air pressure values ​​detected by the multiple air pressure sensors 423 below decrease, the control screen 11 0 controls the electromagnetic ring 420 at the corresponding position above to increase the current, and the magnetic repulsion force applied by the electromagnetic ring 420 to the magnetic block 422 increases. The magnetic block 422 stretches the support spring 421 and drives the gas blocking rod 418 to move away from the end of the detection exhaust cylinder 404. The blocking area of ​​the lateral hole 413 by the gas blocking rod 418 is reduced, and the high-pressure gas inside the matching hole 417 enters the lateral hole 413 and increases the thrust applied to the push block 416. The support force of the push block 416 on the bottom of the elastic support ring capsule 409 increases, and the thrust applied by the elastic support ring capsule 409 to the top of the steel-plastic pipe fitting increases, thereby ensuring that the steel-plastic pipe fitting continuously moves upward and restores the coaxial state, thereby ensuring the stability and coaxiality of the inner moving block 407 when moving inside the steel-plastic pipe fitting.

[0066] As the inner moving block 407 continuously moves inside the steel-plastic pipe fitting, when the inner moving block 407 moves to the crack position, since the high-pressure gas inside the steel-plastic pipe fitting directly discharges along the crack, the air pressure value detected by the air pressure sensor 423 at the corresponding position continuously decreases to the set minimum air pressure value, and the control panel 110 controls the energizing current of the electromagnetic ring 420 at this position to continue increasing. The magnetic repulsion force of the electromagnetic ring 420 on the magnetic block 422 continues to increase. The magnetic block 422 stretches the support spring 421 and drives the air-blocking rod 418 to move away from the detection exhaust cylinder 404 end along the matching hole 417. The blocking area of the air-blocking rod 418 on the side hole 413 decreases, the amount of high-pressure gas inside the docking groove 424 increases, the amount of high-pressure gas inside the docking groove 424 entering the side hole 413 along the matching hole 417 increases, the thrust applied by the high-pressure gas on the push block 416 increases, the extrusion force applied by the push block 416 on the side wall of the elastic support ring bladder 409 increases. At the same time, the solenoid valve 411 at the corresponding position opens, and the magnetic powder inside the elastic support ring bladder 409 directly discharges along the discharge hole 410 and is marked at the corresponding position, thus facilitating subsequent processing procedures for this steel-plastic pipe fitting.

[0067] After that, the inner moving block 407 continues to move inside the steel-plastic pipe fitting. The air pressure value detected by the air pressure sensor 423 is still less than the set minimum air pressure value. The magnetic powder inside the elastic support ring bladder 409 continuously discharges along the discharge hole 410 and marks the crack position. When the marking is completed, that is, after the inner moving block 407 disengages from the crack position, the air pressure values detected by multiple air pressure sensors 423 return to the initial values, indicating that the detection of this steel-plastic pipe fitting is completed. The control panel 110 controls the positioning exhaust cylinder 304 and the detection exhaust cylinder 404 to stop supplying gas, and adjusts the pneumatic rod 308 to return to its original position. Then the elastic sealing ring 307 and the elastic support ring bladder 409 no longer clamp and fix the inner wall of the steel-plastic pipe fitting. After the operator fixes the position of the steel-plastic pipe fitting, the inner moving block 407 moves in the reverse direction to return to its original position. At the same time, the positioning pneumatic rod 302 and the clamping pneumatic rod 402 are started in the reverse direction and drive the positioning exhaust cylinder 304 and the detection exhaust cylinder 404 to move in the reverse direction to disengage from the clamping of the steel-plastic pipe fitting, completing the blanking of the steel-plastic pipe fitting. After that, repeat the above process to re-perform the airtightness detection on the subsequent steel-plastic pipe fittings.

[0068] This detection device has high detection accuracy, good detection effect, meets the actual detection requirements, reduces the operation difficulty, increases the detection range, ensures the detection efficiency, is suitable for the batch production and processing requirements of steel-plastic pipe fittings, is safe and stable, and is green and environmentally friendly. At the same time, it can also perform wind cleaning on the inner wall of the steel-plastic pipe fitting before detection, improving the sealing performance and clamping stability of the subsequent steel-plastic pipe fittings. Moreover, it can accurately position the coaxiality of the steel-plastic pipe fitting to ensure the accurate and stable airtightness detection of the steel-plastic pipe fitting. During the detection process, it further realizes the accurate positioning and marking of the crack position, reducing the subsequent repair difficulty and improving the repair efficiency.
