Description

Technical Field

[0001] The invention belongs to the technical field of air tightness detection of steel-plastic pipes, and in particular is a detection device for steel-plastic pipe production based on intelligent sensing. Background Art

[0002] Steel-plastic pipe fittings are pipe connectors made of a composite of steel and plastic materials. They are corrosion-resistant, pressure-resistant, long-life, and easy to install. They are widely used in construction, municipal administration, petroleum, chemical industry and other fields. They have the advantages of corrosion resistance, pressure resistance, long life and easy installation. The air tightness test of steel-plastic pipe fittings is an important link to ensure their quality and performance. The main purpose of air tightness test is to check whether there is leakage in steel-plastic pipe fittings to ensure that they can maintain sealing performance during use and prevent medium leakage and environmental pollution. There are many methods for air tightness test of steel-plastic pipe fittings, the most common ones include water immersion method, pressure drop method, differential pressure method, direct pressure method and mass flow method.

[0003] Chinese invention patent CN110220653A discloses a double-wall pipe air tightness detection tool and detection method. The detection tool includes a blind cover, a test cover plate, a cover plate, an inlet pipe group, an outlet pipe group and an air inlet pipe. The blind cover blocks the natural gas inlet of the double-wall pipe, and the test cover plate and the cover plate respectively seal the two ends of the double-wall pipe; one end of the inlet pipe group and one end of the outlet pipe group are respectively connected to the test cover plate; the air tightness detection tool has low detection accuracy and poor detection effect.

[0005] When actually testing the air tightness of steel-plastic pipe fittings, if there is dust and impurities on the inner wall of the steel-plastic pipe fittings, it will affect the sealing of the subsequent steel-plastic pipe fittings and ultimately reduce the accuracy of the air tightness test.

[0006] In addition, since the diameters and lengths of steel-plastic pipe fittings are different, and the steel-plastic pipe fittings themselves have gravity and are prone to displacement when they are clamped and fixed, the steel-plastic pipe fittings will be offset and cannot be coaxially clamped and sealed, which will ultimately directly affect the air tightness detection of the steel-plastic pipe fittings.

[0007] At the same time, the steel-plastic pipe fittings detection equipment in the prior art can only detect the presence of cracks in the steel-plastic pipe fittings, but cannot accurately determine the location and size of the cracks, thereby increasing the difficulty of subsequent treatment of the cracks in the steel-plastic pipe fittings.

The setting of the support spring 421 further improves the elastic reset performance of the magnetic stopper 422. The support spring 421 is located outside the gas blocking rod 418. On the surface, the facing end faces of the electromagnetic ring 420 and the magnetic stopper 422 have the same magnetic properties. When the current flowing through the electromagnetic ring 420 increases, the magnetic repulsion of the electromagnetic ring 420 on the magnetic stopper 422 increases, and the magnetic stopper 422 stretches the support spring 421 to move away from the end of the electromagnetic ring 420. The magnetic stopper 422 simultaneously drives the air blocking rod 418 to move. An air pressure sensor 423 is provided at the other end of the magnetic stopper 422. The air pressure sensor 423 is used to detect the air pressure value at the end of the magnetic stopper 422.

[0038] When actually testing the air tightness of steel-plastic pipe fittings, if there are dust and impurities on the inner wall of the steel-plastic pipe fittings, it will affect the subsequent sealing of the steel-plastic pipe fittings and ultimately reduce the accuracy of the air tightness test; and because the diameters and lengths of steel-plastic pipe fittings are different, and the steel-plastic pipe fittings themselves have gravity and are prone to displacement when they are clamped and fixed, the steel-plastic pipe fittings are offset and cannot be coaxially clamped and sealed, directly affecting the air tightness test of the steel-plastic pipe fittings; at the same time, the steel-plastic pipe fittings detection equipment in the prior art can only detect the presence of cracks in the steel-plastic pipe fittings, but cannot accurately determine the location and size of the cracks, thereby increasing the difficulty of subsequent crack treatment of the steel-plastic pipe fittings.

[0039] In order to solve the above problems, when the intelligent sensing-based steel-plastic pipe fittings production detection equipment is actually used, the air pump 106 is started and high-pressure gas is introduced into the transfer box 109 along the air inlet pipe 108 for temporary storage. The connecting plate 211 drives the positioning component 3 and the detection component 4 to the initial position, and then multiple steel-plastic pipe fittings are transferred to the top of the connecting plate 211, and correspond to multiple positioning exhaust cylinders 304 and detection exhaust cylinders 404 in turn. At this time, the steel-plastic pipe fittings are inserted into the outer surface of the positioning exhaust cylinder 304 and squeezed and contacted with the side wall of the support ring 306. At the same time, the clamping pneumatic rod 402 is started and the output end is extended. The output end of the clamping pneumatic rod 402 drives the detection exhaust cylinder 404 to move close to the end of the positioning exhaust cylinder 304 to reach the inside of the steel-plastic pipe fitting, thereby completing the assembly of the steel-plastic pipe fitting, and under the action of gravity, the steel-plastic pipe fittings are squeezed and contacted with the elastic sealing ring 307 and the top of the elastic support ring bag 409.

[0040] Afterwards, the control panel 110 controls the current of the electromagnetic ring 420 to reach the maximum, and the electromagnetic ring 420 applies magnetic repulsion to the magnetic stopper 422 and drives the magnetic stopper 422 to stretch the support spring 421 to move away from the end of the detection exhaust cylinder 404, and the magnetic stopper 422 drives the gas blocking rod 418 to move synchronously. When the gas blocking rod 418 is disengaged from the matching hole 417, the groove 419 is connected to the matching hole 417, and the high-pressure gas inside the transfer box 109 enters the detection exhaust cylinder 404 along the detection exhaust pipe 405, and 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 is finally discharged to the steel-plastic pipe fitting along the groove 419. At the same time, since the elastic sealing ring 307 and the elastic supporting ring capsule 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 finally be discharged along both sides of the steel-plastic pipe fitting, thereby further realizing the wind cleaning effect on the inner wall of the steel-plastic pipe fitting, and avoiding the dust and impurities attached to the inner wall of the steel-plastic pipe fitting from affecting the subsequent air tightness detection. At the same time, in order 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 supporting ring capsule 409 are always in contact with the inner top of the steel-plastic pipe fitting, and then the contact position is continuously changed in coordination with the rotation of the steel-plastic pipe fitting, thereby improving the thoroughness and stability of the cleaning of the inner wall of the steel-plastic pipe fitting.

[0041] After the cleaning of the inner wall of the steel-plastic pipe fitting is completed, the control panel 110 controls the current of the electromagnetic ring 420 to be reduced to the initial value, and the magnetic repulsion force of the electromagnetic ring 420 on the magnetic stopper 422 is reduced. Under the elastic force of the support spring 421, the magnetic stopper 422 is driven to be located in the initial position, and the magnetic stopper 422 drives the gas blocking rod 418 to move in the opposite direction along the matching hole 417 to the initial position, and the gas blocking rod 418 blocks part of the lateral hole 413, and the high-pressure gas inside the docking groove 424 enters the lateral hole 413 along the matching hole 417 and applies a force to the push block 416, and the push block 416 stretches the connecting spring 415 and moves away from the gas blocking rod 4 18 ends move, and the force exerted by the push block 416 on the elastic support ring capsule 409 increases. The corresponding elastic support ring capsule 409 continues to move along the ring groove 408, and the elastic support ring capsule 409 is sealed and squeezed together with the inner wall of the steel-plastic pipe fitting. At the same time, the control panel 110 controls multiple adjustment pneumatic rods 308 to start and the output end extends, and the adjustment pneumatic rods 308 apply 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 constantly collides. Then, the outer surface of the elastic sealing ring 307 is also sealed and squeezed together with the inner wall of the steel-plastic pipe fitting, thereby completing the fixed installation process of the steel-plastic pipe fitting.

[0042] Afterwards, the control panel 110 controls the high-pressure gas inside the transfer box 109 to no longer enter the detection exhaust cylinder 404 along the detection air outlet pipe 405, and the air pressure inside the detection exhaust cylinder 404 entering the docking groove 424 is stable, and the high-pressure gas inside the transfer box 109 enters the positioning exhaust cylinder 304 along the positioning air outlet pipe 305, and the high-pressure gas inside the positioning exhaust cylinder 304 continuously enters the inner cavity of the steel-plastic pipe fitting, and 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, and the air pressure values ​​detected by multiple air pressure sensors 423 continue to increase. If the air pressure values ​​detected by multiple air pressure sensors 423 are all equal, it means 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 bag 409 are sealed and fit to the inner wall of the steel-plastic pipe fitting.

[0043] If the air pressure value detected by the air pressure sensor 423 on one side decreases, it means that the high-pressure gas inside the steel-plastic pipe fitting leaks at this position, that is, the elastic support ring bag 409 at this position is not tightly fitted with the inner wall of the steel-plastic pipe fitting. The most common ones are multiple air pressure sensors 423 under the inner moving block 407. Because the steel-plastic pipe fitting itself has gravity and each is different, the top of the steel-plastic pipe fitting exerts a large extrusion pressure on the top of the elastic support ring bag 409 and the elastic sealing ring 307, which causes the steel-plastic pipe fitting to be out of coaxial with the positioning exhaust pipe 304 and the detection exhaust pipe 404. At this time, it is necessary to increase the supporting force of the elastic support ring bag 409 and the top of the elastic sealing ring 307 on the top of the steel-plastic pipe fitting.

[0044] 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 electromagnetic ring 420 at the corresponding position above to increase the current, the magnetic repulsion of the electromagnetic ring 420 on the magnetic stopper 422 increases, the magnetic stopper 422 stretches the support spring 421 and increases the moving distance away from the detection exhaust pipe 404 end along the matching hole 417, the magnetic stopper 422 simultaneously drives the gas blocking rod 418 to move, the blocking area of ​​the gas blocking rod 418 on the lateral hole 413 is reduced, and at the same time the amount of high-pressure gas inside the docking groove 424 increases The amount of high-pressure gas inside the docking groove 424 that enters the lateral hole 413 along the matching hole 417 increases, the amount of high-pressure gas inside the lateral hole 413 increases and the thrust applied to one side of the push block 416 increases, the extrusion pressure applied by the other side of the push block 416 to the side wall of the elastic support ring capsule 409 increases, and the moving distance of the elastic support ring capsule 409 along the annular groove 408 increases, further improving the degree of fit between the elastic support ring capsule 409 and the inner wall of the steel-plastic pipe fitting at this position, thereby improving the sealing effect of the elastic support ring capsule 409 on the inner wall of the steel-plastic pipe fitting.

[0045] 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 extend the output end, and the output end of the adjustment pneumatic rod 308 increases the extrusion force applied to the elastic sealing ring 307. The elastic sealing ring 307 elastically expands at this position and increases the thrust applied to the top of the steel-plastic pipe fitting. The elastic support ring bag 409 cooperates with the steel-plastic pipe fitting to continuously move upward to a suitable position, thereby ensuring the coaxial arrangement of the steel-plastic pipe fitting with the positioning exhaust cylinder 304 and the detection exhaust cylinder 404, thereby correspondingly improving the subsequent detection accuracy of the air tightness of the steel-plastic pipe fitting.

[0046] After that, the air tightness test of the inner wall of the steel-plastic pipe fitting can be carried out, that is, the control panel 110 controls the mobile hydraulic rod 210 to start and shorten the output end, the output end of the mobile hydraulic rod 210 drives the slider 209 to move downward along the slide 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 multiple positioning exhaust cylinders 304, the detection exhaust cylinder 404 and the steel-plastic pipe fittings therebetween to move downward to the inside of the detection chamber 102, the steel-plastic pipe fittings are immersed in the clean water inside the detection chamber 102, at this time, since the steel-plastic pipe fittings are filled with high-pressure gas along the positioning exhaust cylinder 304, if there are large cracks inside the steel-plastic pipe fittings, the high-pressure gas can be directly discharged along the cracks and generate bubbles inside the clean water, with the help of the bubbles, the crack position can be determined, so as to carry out subsequent processes.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] As the inner moving block 407 continues to move 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 is directly discharged along the crack, the air pressure value detected by the air pressure sensor 423 at the corresponding position continues to decrease to the set minimum air pressure value, and the control panel 110 controls the current of the electromagnetic ring 420 at this position to continue to increase, and the magnetic repulsion force of the electromagnetic ring 420 on the magnetic stopper 422 continues to increase, and the magnetic stopper 422 stretches the support spring 421 and drives the gas blocking rod 418 along the matching hole 417 to move away from the detection exhaust pipe 40 The 4 ends move, and the blocking area of ​​the gas blocking rod 418 on the lateral hole 413 is reduced, the amount of high-pressure gas in the docking groove 424 increases, and the amount of high-pressure gas in the docking groove 424 that enters the lateral hole 413 along the matching hole 417 increases, and the thrust applied by the high-pressure gas to the push block 416 increases, and the extrusion pressure applied by the push block 416 to the side wall of the elastic support ring bag 409 increases. At the same time, the electromagnetic valve 411 at the corresponding position is opened, and the magnetic powder inside the elastic support ring bag 409 is directly discharged along the discharge hole 410 and marked at the corresponding position, thereby facilitating the subsequent processing of the steel-plastic pipe fitting.

[0051] After that, the inner moving block 407 continues to move along the inside of the steel-plastic pipe fitting, and 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 bag 409 is continuously discharged along the discharge hole 410 and marks the crack position. When the marking is completed, that is, the inner moving block 407 is separated from the crack position, the air pressure values ​​detected by the multiple air pressure sensors 423 return to the initial value, indicating that the steel-plastic pipe fitting has completed the detection, and the control panel 110 controls the positioning exhaust pipe 304 and the detection exhaust pipe 404 to stop supplying air, and adjusts When the throttling rod 308 returns to its original position, the elastic sealing ring 307 and the elastic supporting ring bag 409 no longer clamp 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 opposite 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 opposite direction and drive the positioning exhaust cylinder 304 and the detection exhaust cylinder 404 to move in the opposite direction to disengage from the clamping of the steel-plastic pipe fitting, completing the unloading of the steel-plastic pipe fitting. Thereafter, the above process is repeated to re-test the air tightness of the subsequent steel-plastic pipe fittings.

[0052] The detection equipment has high detection accuracy and good detection effect, meets actual detection needs, reduces operation difficulty, increases detection range, ensures detection efficiency, is suitable for batch production and processing needs of steel-plastic pipe fittings, is safe, stable, and environmentally friendly; at the same time, before detection, the inner wall of the steel-plastic pipe fitting can be cleaned by wind to improve the subsequent sealing and clamping stability of the steel-plastic pipe fittings, and can also accurately locate the coaxiality of the steel-plastic pipe fittings to ensure accurate and stable airtightness detection of the steel-plastic pipe fittings; during the detection process, the precise positioning and marking of the crack position can be further realized to reduce the difficulty of subsequent repairs and improve repair efficiency.
