Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline crack detection, and in particular relates to an intelligent detection device for buried pressure pipelines. Background Art

[0002] Buried pressure piping refers to all pipelines that are subject to internal or external pressure, regardless of the medium inside the pipe. Buried pressure piping is a part of the pipeline that is used to transport, distribute, mix, separate, discharge, meter, control and stop the flow of fluids. It is usually an assembly consisting of pipes, fittings, flanges, bolted connections, gaskets, valves and other components or pressure-bearing parts and supports.

[0003] During the development of this utility model, the inventors discovered that this technology suffers from at least the following issues: Existing buried pressure pipelines must be inspected for cracks using a detection device before leaving the factory to ensure they are free of internal cracks. However, when the detection device is in operation, it typically only inspects one side of the buried pressure pipeline using the relevant instrument, resulting in an incomplete inspection and unreliable test results.

[0004] To this end, we propose an intelligent detection device for buried pressure pipelines to solve the above problems. Utility Model Content

[0005] The main purpose of the present invention is to provide an intelligent detection device for buried pressure pipelines, so that all positions on the buried pressure pipelines can be detected, making the detection of buried pressure pipelines more comprehensive and the detection structure more reliable, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A buried pressure pipeline intelligent detection device includes a base, an upper boss integrally welded to the base, and an intelligent detection mechanism located on the upper boss. Three movable motors are horizontally mounted on a side wall of the upper boss. An arcuate groove for placing a pipeline to be detected is formed on a side of the upper boss facing away from the three movable motors, and the arcuate groove penetrates the top wall of the upper boss. Three side grooves are formed on the inner wall of the arcuate groove, each of which has a plurality of openings distributed at equal intervals. The output shafts of the three movable motors are coaxially connected to inner support shafts, and each inner support shaft is fixedly sleeved with a plurality of rollers. The plurality of rollers on the inner support shafts extend from the plurality of openings located on the inner wall of the arcuate groove in one of the side grooves.

[0008] Extension seats are symmetrically welded on both sides of the top wall of the upper boss, and slide grooves are formed above the two extension seats. A conveying mechanism is also provided on the upper boss, and the conveying mechanism includes a servo motor horizontally installed on one of the extension seats, screws and slide rods respectively located in the two slide grooves, and a bracket located above the two extension seats, wherein the output shaft of the servo motor is coaxially connected to the screw, and both sides of the slide rod are welded to the extension seat, one side of the bracket extends into one of the slide grooves and is threadedly sleeved on the screw, and the other side extends into the other slide groove and is slidably sleeved on the slide rod. The intelligent detection mechanism includes a crack comprehensive detector mounting seat welded on the bracket and a crack comprehensive detector installed on the inner side of the crack comprehensive detector mounting seat. The technical principle of the crack comprehensive detector is the existing technology, and it is a technically mature product.

[0009] As a preferred embodiment, there are three inner support shafts and they are all arranged horizontally, wherein the three inner support shafts are respectively located in the three side grooves, and the three inner support shafts are all rotatably connected to the base; so that the three inner support shafts operate stably, and at the same time, the three inner support shafts are parallel to each other.

[0010] As a preferred embodiment, the multiple rollers on the inner support shaft are distributed at equal intervals in the horizontal direction; and since the multiple rollers extend from the openings of the side grooves located on the inner wall of the arc-shaped groove, the multiple rollers can contact the pipeline to be inspected and flip the pipeline by rotating the rollers.

[0011] As a preferred embodiment, the screw and the sliding rod are both arranged horizontally, and both sides of the screw are rotatably connected to the extension seat; so that the screw can operate stably under the drive of the servo motor, and the mobile motor and the servo motor require different external power facilities for power supply.

[0012] As a preferred embodiment, the crack comprehensive detector mounting seat is in the shape of a U and passes through the top and bottom walls of the bracket; so that the crack comprehensive detector on the inside of the crack comprehensive detector mounting seat can perform crack detection on the pipeline to be detected below it.

[0013] In summary, the technical effects and advantages of the utility model are:

[0014] The intelligent detection device for buried pressure pipelines is provided with an intelligent detection mechanism above the pipeline to be detected, so that the buried pressure pipeline to be detected can be detected by the comprehensive crack detector of the intelligent detection mechanism after leaving the factory. Because the comprehensive crack detector can be translated outside the buried pressure pipeline under the action of the conveying mechanism, moving from one side to the other, all positions on the buried pressure pipeline can be detected, making the detection of the buried pressure pipeline more comprehensive and the detection structure more reliable.

[0015] This intelligent detection device for buried pressure pipelines drives three mobile motors to operate, causing three inner support shafts and the rollers thereon to rotate in the same direction, so that the buried pressure pipeline to be inspected is flipped at a certain angle. Then, at this angle, crack detection is performed on various positions of the buried pressure pipeline to be inspected. In this way, the crack detection on the buried pressure pipeline to be inspected can be more comprehensive to ensure that it is qualified before leaving the factory.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figures 1-4 A buried pressure pipeline intelligent detection device includes a base 1, an upper boss 2 integrally welded to the base 1, and an intelligent detection mechanism located on the upper boss 2. Three movable motors 3 are horizontally mounted on one side wall of the upper boss 2. An arcuate groove 4 for placing the pipeline to be detected is formed on the side of the upper boss 2 facing away from the three movable motors 3. The arcuate groove 4 passes through the top wall of the upper boss 2 and has three side grooves 5 formed on the inner wall of the arcuate groove 4. Each side groove 5 has a plurality of openings distributed at equal intervals on the inner wall of the arcuate groove 4.

[0023] The output shafts of the three moving motors 3 are coaxially connected to the inner support shafts 6. It should be noted that there are three inner support shafts 6 in total and they are all arranged horizontally. The three inner support shafts 6 are respectively located in the three side grooves 5, and the three inner support shafts 6 are rotatably connected to the base 1, so that the three inner support shafts 6 can operate stably. At the same time, the three inner support shafts 6 are parallel to each other, and each inner support shaft 6 is fixedly sleeved with a plurality of rollers 7, and the plurality of rollers 7 on the inner support shaft 6 respectively extend from a plurality of openings on the inner wall of the arc-shaped groove 4 of one of the side grooves 5. The plurality of rollers 7 on the inner support shaft 6 are equally spaced in the horizontal direction. Since the plurality of rollers 7 extend from the openings on the inner wall of the arc-shaped groove 4 of the side groove 5, the plurality of rollers 7 can contact the pipeline to be inspected and flip the pipeline by the rotation of the rollers 7.

[0024] Extension seats 8 are symmetrically welded on both sides of the top wall of the upper boss 2, and slide grooves 10 are formed above the two extension seats 8. A conveying mechanism is also provided on the upper boss 2, which includes a servo motor 9 horizontally mounted on one of the extension seats 8, a screw 11 and a slide rod 12 respectively located in the two slide grooves 10, and a bracket 13 located above the two extension seats 8, wherein the output shaft of the servo motor 9 is coaxially connected to the screw 11, and both sides of the slide rod 12 are welded to the extension seat 8, one side of the bracket 13 extends into one of the slide grooves 10 and is threadedly sleeved on the screw 11, and the other side extends into the other slide groove 10 and is slidably sleeved on the slide rod 12, the screw 11 and the slide rod 12 are both horizontally arranged, and both sides of the screw 11 are rotatably connected to the extension seat 8, so that the screw 11 can operate stably under the drive of the servo motor 9, and the mobile motor 3 and the servo motor 9 require different external power facilities for power supply;

[0025] The intelligent detection mechanism includes a crack comprehensive detector mounting base 14 welded on the bracket 13 and a crack comprehensive detector 15 installed on the inner side of the crack comprehensive detector mounting base 14. The technical principle of the crack comprehensive detector 15 is the existing technology and is a technically mature product. The crack comprehensive detector mounting base 14 is in the shape of a U, and the crack comprehensive detector mounting base 14 passes through the top and bottom walls of the bracket 13, so that the crack comprehensive detector 15 on the inner side of the crack comprehensive detector mounting base 14 can perform crack detection on the pipeline to be detected below it.

[0026] The intelligent detection device for buried pressure pipelines: When in use, the buried pressure pipeline to be detected is first placed flat in the arc-shaped groove 4, so that the outer wall of the buried pressure pipeline to be detected contacts the three sets of rollers 7, and then the comprehensive crack detector 15 is used to detect cracks in the buried pressure pipeline to be detected below it. The technical principle and operation method of the detection are all existing technologies. Then, the servo motor 9 can be driven to drive the screw 11 to operate, so that the bracket 13 moves a distance along with the slide rod 12, thereby facilitating the comprehensive crack detector 15 to detect other positions on the buried pressure pipeline to be detected. In this way, the detection range of the buried pressure pipeline to be detected is expanded (the servo motor 9 is a bidirectional motor);

[0027] After the above-mentioned inspection process is completed, the three moving motors 3 should be driven to operate, driving the three inner support shafts 6 and the rollers 7 thereon to rotate in the same direction, so that the buried pressure pipeline to be inspected is flipped at a certain angle (for example, 30°), and then at this angle, the crack detection at various positions of the buried pressure pipeline to be inspected is carried out... In this way, the detection of cracks on the buried pressure pipeline to be inspected can be more comprehensive to ensure that it is qualified before leaving the factory.
