Description

Technical Field

[0001] The present invention relates to the technical field of suspension transportation, and more specifically, to a pipeline detection and transportation system provided with a suspension auxiliary structure. Background Art

[0002] Among the many modes of transportation of crude oil, natural gas and refined oil, pipeline transportation occupies an extremely important position. Oil and gas pipelines are key components of the pipeline transportation system. In the actual pipeline laying and connection process, the interconnection between oil and gas pipelines is mostly achieved by welding. Therefore, it is necessary to use defect detection equipment to perform detailed defect detection on the welds at the connection of oil and gas pipelines to ensure the welding quality and transportation safety between oil and gas pipelines.

[0003] In the prior art, for example, the invention patent with application number CN202410369759.0 discloses a pipeline nondestructive flaw detection device, which includes a support mechanism, multiple flaw detection mechanisms and multiple driving mechanisms. The support mechanism includes multiple support tubes, and the multiple support tubes are coaxially spaced. Multiple flaw detection mechanisms and multiple support tubes are correspondingly arranged, and the flaw detection mechanisms are installed in the corresponding support tubes for elastically clamping the pipeline and detecting the pipeline. Multiple driving mechanisms and multiple support tubes are correspondingly arranged, and the driving mechanisms are installed on the corresponding support tubes. The driving mechanisms have a first state and a second state. In the first state, the driving mechanism is used to drive the pipeline to rotate. In the second state, the driving mechanism is used to drive the pipeline to move along the length direction of the support tube. In this flaw detection device, the driving mechanism directly acts on the pipeline surface during transportation, which is easy to cause secondary damage to the pipeline. When the length of the pipeline is large, the two ends of the pipeline are bent and deformed under the action of gravity. Excessive bending will also cause damage such as tearing at the weld, affecting the detection accuracy.

[0004] Therefore, it is necessary to propose a pipeline inspection and transportation system provided with a suspension auxiliary structure to at least partially solve the problems existing in the prior art. Summary of the invention

[0069] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0070] Embodiment 1:

[0071] like Figure 1 As shown, the present invention provides a pipeline detection and conveying system provided with a suspension auxiliary structure, comprising:

[0072] Ultrasonic testing unit, which is used to detect defects in the pipeline at its center;

[0073] A pipeline propulsion unit, which is arranged at the front end of the ultrasonic detection unit and is used to clamp one end of the pipeline and propel it into the ultrasonic detection unit;

[0074] The suspension auxiliary unit is arranged at the rear end of the ultrasonic detection unit and is used to suspend and support the other end of the pipeline. The suspension auxiliary unit and the pipeline propulsion unit are fed synchronously.

[0075] The working principle and beneficial effects of the above technical solution are:

[0076] The present invention provides a pipeline detection and conveying system with a suspension auxiliary structure, which uses ultrasound to detect pipeline defects; during the detection process, the pipeline is moved to the detection station by hoisting or the like, a pipeline propulsion unit clamps one end of the pipeline and conveys it into the ultrasonic detection unit, the pipeline passes through the center of the ultrasonic detection unit, and is gradually fed along the length direction as the pipeline propulsion unit moves, thereby fully detecting each position of the pipeline; a suspension auxiliary unit is arranged at the rear end of the ultrasonic detection unit to suspend and support the other end of the pipeline, and moves synchronously with the pipeline propulsion unit.

[0077] Through the above structural design, when inspecting the pipeline, a fixing method of clamping at one end and hanging at the other end is adopted, so that the two ends of the pipeline are at the same height and pass through the center of the ultrasonic detection unit, reducing the bending deformation at both ends of the pipeline, ensuring that the pipeline is evenly stressed during the ultrasonic detection process, preventing secondary damage defects caused by bending of the pipeline during or after the detection, and ensuring the accuracy of the detection results; at the same time, the hanging-assisted method greatly reduces the length of the ground track and releases ground space.

[0078] Embodiment 2:

[0079] On the basis of the above-mentioned embodiment 1, a pressure sensor is provided in the ultrasonic detection unit for detecting the force values ​​in various directions of the pipeline; the controller controls the hanging position of the hanging auxiliary unit according to the detection data of the pressure sensor so that the force in various directions of the pipeline is uniform.

[0080] The working principle and beneficial effects of the above technical solution are:

[0081] A pressure sensor is installed in the ultrasonic detection unit to detect the stress conditions in all directions of the pipeline to evaluate the position of the pipeline, and adjust the position of the suspension auxiliary unit based on this to prevent the pipeline from being deformed and damaged secondary due to unbalanced force during feeding.

[0082] Embodiment 3:

[0083] like Figure 1 , Figure 2 As shown, based on the above embodiment 1, the suspension auxiliary unit includes:

[0084] An electric suspension track 31, the electric suspension track 31 is arranged on the top of the factory building;

[0085] The telescopic suspension frame 32 is connected to the lower part of the electric suspension track 31 and has an adjustable height. The telescopic power end of the telescopic suspension frame 32 is connected to the controller, and the telescopic suspension frame 32 moves along the moving direction of the pipeline;

[0086] The clamp assembly includes two left and right semicircular clamps 33, the top of the clamp 33 is hinged to the telescopic suspension frame 32, and lugs 34 are set at the bottom ends of the two clamps 33, and the lugs 34 are connected by bolts; a ball 35 is set on the inner wall of the clamp 33, and the pipe clamp is set between the two clamps 33.

[0087] The working principle and beneficial effects of the above technical solution are:

[0088] When the suspension auxiliary unit is in use, the controller adjusts the length of the telescopic suspension frame 32 to adapt it to the height of the pipeline, passes the pipeline between the two clamps 33, closes the clamp 33, connects the lug 34 at the bottom of the clamp 33 with bolts, and the pipeline contacts the ball 35 in the clamp 33, which can rotate freely while stably clamping; when the suspension auxiliary unit moves, the electric suspension track 31 is started to drive the telescopic suspension frame 32 on it to move, and feed synchronously with the pipeline propulsion unit. The electric suspension track 31 of the suspension auxiliary unit is improved on the existing hoisting track of the factory building to reduce production costs.

[0089] Embodiment 4:

[0090] like Figure 1 As shown, based on the above embodiment 1, the pipeline propulsion unit includes:

[0091] An electric slide rail 41 is arranged on the floor of the plant and along the moving direction of the pipeline, and a traveling trolley 42 is arranged on the electric slide rail 41;

[0092] The propulsion frame 43 is installed above the walking trolley 42. The propulsion frame 43 is provided with an adaptive clamping assembly and a rotating motor 45. The adaptive clamping assembly is used to clamp the pipeline, and the rotating motor 45 is used to drive the pipeline to rotate.

[0093] The working principle and beneficial effects of the above technical solution are:

[0094] When the pipeline propulsion unit is used, the pipeline is moved to the detection line by hoisting, and its height is adjusted to correspond to the height of the adaptive clamping assembly. The electric slide rail 41 is started to drive the walking trolley 42 thereon to move, and the propulsion frame 43 carries the adaptive clamping assembly close to the pipeline and automatically clamps the end of the pipeline; a rotating motor 45 is set on one side of the propulsion frame 43, which can drive the adaptive clamping assembly to rotate and make the pipeline rotate accordingly. When performing the detection work, the electric slide rail 41 and the rotating motor 45 are started to propel the pipeline along the length direction and rotate around its own axis at the same time, so that the ultrasonic detection unit can detect various positions of the pipeline, improve the comprehensiveness and accuracy of the detection, and reduce the possibility of missed detection.

[0095] Embodiment 4:

[0096] like Figure 3-Figure 5 As shown, based on the above embodiment 1, the adaptive clamping assembly includes:

[0097] A transmission disc 44, the transmission disc 44 is connected to the propulsion frame 43, the transmission disc 44 is arranged near an opening on one side of the ultrasonic detection unit, and a rotating motor 45 is connected to the other side of the transmission disc 44;

[0098] The rotating frame 46 is rotatably disposed in the transmission plate 44. The rotating frame 46 contacts the side wall of the transmission plate 44 and has a predetermined friction force. The rotating frame 46 includes three outwardly extending arms.

[0099] A central gear 47, the central gear 47 is rotatably connected to the center of the transmission plate 44, a rotating shaft 48 is disposed at the center of the central gear 47, and the rotating shaft 48 passes through the center of the rotating frame 46 and is connected to the output shaft of the rotating motor 45;

[0100] Planetary gears 49, which are provided in three numbers and are rotatably connected to three arms of the rotating frame 46 respectively, and the planetary gears 49 are meshedly connected with the central gear 47;

[0101] An inner clamping rod 51, the inner clamping rod 51 is connected to the rotating shaft of the planetary gear 49 and extends outward from the transmission plate 44;

[0102] An inner friction roller 52, the inner friction roller 52 is connected to a side of the extended end of the inner clamping rod 51 close to the ultrasonic detection unit;

[0103] The limiting member 53 is connected to the inner clamping rod 51 and arranged on the outer side of the inner friction roller 52 .

[0104] The working principle and beneficial effects of the above technical solution are:

[0105] When the adaptive clamping assembly is in use, the rotating motor 45 is started, and the central gear 47 is driven to rotate through the output shaft. Due to the friction between the rotating frame 46 and the transmission disk 44, the rotating frame 46 does not rotate; the central gear 47 is meshed with the planetary gear 49 for transmission, and the inner clamping rod 51 is driven to rotate synchronously through the rotating shaft of the planetary gear 49; in the initial position, the inner clamping rod 51 is close to the center of the transmission disk 44. As the rotating shaft of the planetary gear 49 rotates, the inner clamping rod 51 gradually extends outward until the inner friction roller 52 contacts and abuts against the inner wall of the pipeline, clamping the inner wall of the pipeline; a limit piece 53 is provided on the inner clamping rod 51 to limit the end of the pipeline to prevent the clamping distance of the pipeline from being too long and colliding with the transmission components.

[0106] Through the above-mentioned structural design, the inner clamping rod 51 can be automatically unfolded under the drive of the rotating motor 45, and multiple inner friction rollers 52 are supported on the inner side of the pipeline, so as to fix the inner side of the pipeline and evenly apply force, thereby reducing the clamping deformation of the pipeline; and the inner clamping rod 51 can automatically adapt to pipelines of different sizes through different unfolding degrees, without the need to replace parts, thereby improving the detection efficiency; the inner friction roller 52 has sufficient friction with the inner wall of the pipeline, thereby reducing the displacement of the pipeline during detection and transportation.

[0107] Embodiment 5:

[0108] like Figure 3-Figure 5 As shown, based on the above embodiment 1, the adaptive clamping assembly further includes:

[0109] A swing slot 54, which is disposed at one end of the support arm of the rotating frame 46 away from the center;

[0110] Slide grooves 55, two slide grooves 55 are symmetrically arranged on both sides of the inner wall of the swing groove 54, and extend along the length direction of the support arm of the rotating frame 46;

[0111] An outer clamping rod 56, which is rotatably disposed in the swing slot 54 and has one end extending out of the transmission plate 44;

[0112] A slide column 57, which is disposed at the other end of the outer clamping rod 56. The slide column 57 is slidably connected in the slide groove 55. A spring C58 is sleeved on the slide column 57, and two ends of the spring C58 are respectively connected to the outer clamping rod 56 and the inner wall of the swing groove 54;

[0113] The electromagnetic driving member includes a first magnetic block and a second magnetic block. The first magnetic block is connected to one end of the swing slot 54 close to the center of the rotating frame 46, and the second magnetic block is connected to the end of the outer clamping rod 56. When the first magnetic block and the second magnetic block are energized, a repulsive force or an attractive force is generated to drive the outer clamping rod 56 to move toward the outside or inside of the transmission disk 44.

[0114] The outer friction roller 59 is connected to a side of the extended end of the outer clamping rod 56 close to the ultrasonic detection unit.

[0115] The working principle and beneficial effects of the above technical solution are:

[0116] The adaptive clamping assembly is also provided with an external clamping assembly. When the pipeline is installed, the controller energizes the electromagnetic drive component, so that the first magnetic block and the second magnetic block generate a repulsive force, thereby pushing the external clamping rod 56 to move outside the transmission disk 44, and the sliding column 57 on the external clamping rod 56 slides along the sliding groove 55, increasing the space between the inner friction roller 52 and the outer friction roller 59, which is convenient for pipeline installation. When the rotating shaft of the rotating motor 45 rotates, the central gear 47 and the planetary gear 49 rotate until the inner clamping rod 51 extends and the inner friction roller 52 contacts the inner wall of the pipeline. The inner clamping rod 51 no longer rotates, thereby driving the support arm of the rotating frame 46 to rotate, that is, the rotating frame 46 overcomes the friction force and rotates. At the same time, when the external clamping rod 56 rotates to the top of the transmission disk 44, the controller energizes the electromagnetic drive component, so that the first magnetic block and the second magnetic block generate an attractive force, and the external clamping rod 56 moves to the transmission disk 44 under the action of magnetic attraction and gravity until the outer friction roller 59 contacts the outer wall of the pipeline. Under the joint clamping action of the outer friction roller 59 and the inner friction roller 52 , the pipeline is stably connected to the rotating frame and can rotate synchronously with the rotating motor 45 when it rotates.

[0117] Through the above structural design, an external clamping assembly is set on the adaptive clamping assembly, and under the joint action of the inner friction roller 52 and the outer friction roller 59, the pipeline is stably clamped, adapted to pipelines of different sizes, and can adapt to the irregular structure outside the pipeline. When the pipeline is installed, the outer friction roller 59 and the inner friction roller 52 can both extend outward or inward, leaving enough space for pipeline installation and reducing the difficulty of clamping; when the inner and outer clamping points are clamped at the same time, the line connecting the inner and outer clamping points does not pass through the center of the circle, which limits the rotation of the pipeline and prevents displacement in the circumferential direction during feeding and detection.

[0118] Embodiment 6:

[0119] like Figure 3-Figure 5 As shown, based on the above embodiment 1, the adaptive clamping assembly further includes:

[0120] An adjustment groove 61, which is disposed at the top of the transmission disc 44, wherein the connection between the adjustment groove 61 and the edge of the transmission disc 44 is configured as an inclined surface, and the outer clamping rod 56 is slidably disposed at the edge of the transmission disc 44 and in the adjustment groove 61;

[0121] The limit card strip 62 is arranged on the side wall of the swing slot 54 close to the ultrasonic detection unit and extends along the length direction of the support arm of the rotating frame 46. The limit card strip 62 is evenly provided with a plurality of card slots;

[0122] A limit block 63, the limit block 63 is connected to the side wall of the outer clamping rod 56, and the limit block 63 is adapted to the limit strip 62;

[0123] Spring D64 , the spring D64 is sleeved on the limiting block 63 and one end of the spring D64 is connected to the outer clamping rod 56 .

[0124] The working principle and beneficial effects of the above technical solution are:

[0125] When the outer clamping rod 56 rotates to the top of the transmission disk 44, the outer clamping rod 56 moves along the inclined surface to the adjustment groove 61. Under the action of the spring D64, the outer clamping rod 56 moves into the adjustment groove 61, even if the outer clamping rod 56 tilts, the limit block 63 and the limit card strip 62 are separated at this time; at the same time, the controller energizes the electromagnetic drive component, so that the first magnetic block and the second magnetic block generate attraction, and the outer clamping rod 56 moves slightly to the inside or outside of the transmission disk 44 under the action of magnetic attraction and gravity, and the clamping state here is readjusted so that the outer friction roller 59 adapts to the end of the pipeline and keeps the pipeline pressed. After the outer clamping rod 56 moves out of the adjustment groove 61, under the squeezing action of the edge of the transmission disk 44, the outer clamping rod 56 rotates and resets, and the limit block 63 and the limit card strip 62 are clamped again.

[0126] Through the above structural design, the adjustment groove 61 is provided. When the pipe is initially clamped, as the rotating frame 46 rotates, when the outer clamping rod 56 passes through the adjustment groove 61, the outer clamping rod 56 quickly moves inward and clamps the pipe through the outer friction roller 59. During the pipe rotation and feeding process, the clamping position may deviate due to uneven force, or the clamping position may be separated due to imbalance at both ends, which may affect the stability of the pipeline detection process. During the detection process, when each outer clamping rod 56 rotates to the top of the transmission disk 44, the outer clamping rod 56 can be reopened in the adjustment groove 61 to clamp and adjust the outer friction roller 59; the outer friction rollers 59 on the other two outer clamping rods 56 remain in a clamped state, thereby ensuring that they can still rotate stably during the clamping adjustment process; in addition, during the adjustment process, the stress of the current clamping position can be released to avoid deformation of the pipeline and the outer friction roller 59 caused by long-term clamping; after the adjustment is completed, a limit block 63 and a limit strip 62 are set to lock and clamp, which can keep the position of the outer clamping rod 56 stable and will not shift during the rotation and feeding of the pipeline.

[0127] Embodiment 7:

[0128] like Figure 6-Figure 14 As shown, based on the above embodiment 1, the ultrasonic detection unit includes:

[0129] A base 1 is provided with a movable ring 2 on the inner side of the base 1, a rack 3 is connected to the outer side of the movable ring 2, an ultrasonic detection ring 4 is movably connected to one side of the base 1, a detection probe is provided on the ultrasonic detection ring 4, and the detection probe is connected to the controller; a threaded rod 5 is rotatably provided at one end of the ultrasonic detection ring 4, a motor 6 is connected inside the base 1, a rotating shaft 7 is provided at the output end of the motor 6, a pulley A8 is connected to the outer side of the rotating shaft 7, a pulley B10 is provided on one side of the pulley A8, and a reciprocating screw 11 is connected to one end of the pulley B10, The outer side of the reciprocating screw 11 is connected to a piston 12, and an air inlet pipe 13 is arranged on the outer side of the piston 12. The air inlet pipe 13 is connected to the upper end of the base 1, and the upper end of the base 1 is connected to a fixing frame 16, and a guide pipe 17 is connected to the inside of the fixing frame 16. A movable block 18 is arranged inside the guide pipe 17, and a spring A19 is connected to one end of the movable block 18. A cleaning block 20 is connected to the inner side of the movable ring 2, and a cleaning ball 21 is connected to the inside of the cleaning block 20. A support rod 22 is connected to one side of the cleaning block 20, and a spring B23 is arranged on the outer side of the support rod 22;

[0130] The base 1 is provided with two groups, wherein the movable ring 2 is movably connected to the inner side of the base 1, and the rack 3 is connected to the outer side of the movable ring 2. A gear is provided at the lower end of the rack 3, and the gear is meshed with the rack 3. When in use, the staff places the welded pipeline at the inner center of the movable ring 2, and then drives the rack 3 to rotate through the gear. Since the movable ring 2 is movably connected, and the rack 3 is fixedly connected to the movable ring 2, when the gear drives the rack 3 to rotate, the movable ring 2 will be driven to rotate.

[0131] Among them, the upper end of the base 1 is connected to a fixed plate, and a positioning block is rotatably connected inside the fixed plate and can be locked. The threaded rod 5 is threadedly connected to the positioning block, and a guide column is slidably connected to the positioning block, and the end of the guide column is connected to the ultrasonic detection ring 4. After placing the pipeline inside the movable ring 2, the staff rotates the positioning block to place the ultrasonic detection ring 4 outside the pipeline. The positioning block can be rotated to any angle and then locked; then by rotating the threaded rod 5, the distance between the ultrasonic detection ring 4 and the pipeline is adjusted, and the ultrasonic detection ring 4 contacts the outer wall of the pipeline and maintains a stable relative position, so as to detect cracks inside the pipeline through ultrasound, and also detect whether there is air leakage at the welding point to prevent accidents during later use; as the pipeline rotates and feeds, all positions of the pipeline are fully detected.

[0132] Among them, the motor 6 is connected inside the base 1, and its rotating shaft 7 is connected to the output end of the motor 6. The end of the rotating shaft 7 away from the motor 6 is connected to the gear. The outer side of the rotating shaft 7 is connected to the pulley A8, and the pulley A8 is provided with two groups of notches, and the two groups of notches are sleeved with belts 9. Two groups of pulleys B10 are provided on both sides of the pulley A8, and the pulleys B10 and the pulleys A8 are connected by belts 9. When the device is used, the rotating shaft 7 is driven to rotate by the motor 6. When the rotating shaft 7 rotates, the gear is fixedly connected to the rotating shaft 7, which will drive the gear to rotate synchronously. When the rotating shaft 7 rotates, it will drive the pulley A8 to rotate synchronously. When the pulley A8 rotates, it will drive the two groups of pulleys B10 on both sides to rotate synchronously through the two groups of belts 9.

[0133] Among them, the reciprocating screw 11 is connected to one end of the two sets of pulleys B10 close to the outside, and the two sets of reciprocating screws 11 are connected to the outside of the piston 12. The piston 12 is connected to the ball nut pair of the reciprocating screw 11. The air intake pipe 13 is located on the outside of the piston 12. The inner diameter of the air intake pipe 13 matches the outer diameter of the piston 12. One end of the air intake pipe 13 extends to the inside of the base 1, and the air intake pipe 13 is fixed by connecting to the base 1. When the two sets of pulleys B10 rotate, the two sets of reciprocating screws 11 will be driven to rotate synchronously. When the reciprocating screw 11 rotates, the piston 12 will be driven to move back and forth, so that when the piston 12 moves back and forth, it will enter the inside of the air intake pipe 13. At the same time, because the piston 12 matches the inner diameter of the air intake pipe 13, when the piston 12 moves inside the air intake pipe 13, the air pressure will be squeezed and gradually enter the rear end of the air intake pipe 13.

[0134] Among them, the end of the air intake pipe 13 away from the pulley B10 is connected to a connecting pipe 14, and the connecting pipe 14 penetrates the base 1 and extends to the outside. The end of the connecting pipe 14 away from the air intake pipe 13 is connected to an air pressure valve 15, and a fixing frame 16 is connected to the base 1. Two sets of guide pipes 17 are connected inside the fixing frame 16, and the guide pipes 17 are connected to the air pressure valve 15 through the connecting pipe 14. After the air pressure gradually enters the rear end of the air intake pipe 13, it will enter the inside of the air pressure valve 15 through the connecting pipe 14. The upper end of the air pressure valve 15 is provided with a valve, and the valve will be automatically pushed open when a certain pressure value is reached, so that the air pressure will quickly enter the inside of the guide pipe 17 through the connecting pipe 14 at the upper end of the air pressure valve 15.

[0135] Among them, the movable block 18 is movably connected inside the guide tube 17, and the outer diameter of the movable block 18 matches the guide tube 17. The outer wall of the movable block 18 is provided with a plurality of empty slots. One end of the movable block 18 close to the inner side of the guide tube 17 is connected with a spring A19, and the other end of the spring A19 is connected with the inner wall of the movable block 18. When the air pressure quickly enters the inside of the guide tube 17, the movable block 18 will be quickly pushed out, so that the movable block 18 will strike the welding and heat-stressed parts of the outer wall of the pipeline, so that the weld metal will be plastically deformed, thereby offsetting part of the welding stress, effectively reducing the welding stress concentration, and improving the density and strength of the weld. After the guide tube 17 is ejected, the air pressure will be released through the plurality of empty slots on the outer wall. After the pressure is released, the movable block 18 will automatically reset to the inside of the guide tube 17 by the force of the spring A19.

[0136] Among them, there are several groups of support rods 22 movably connected inside the movable ring 2, the interior of the support rods 22 is hollow, and the multiple groups of support rods 22 are connected to a cleaning block 20 at one end on the inner side of the movable ring 2; the cleaning block 20 is connected to the hollow part inside the support rod 22, and the cleaning ball 21 is movably connected inside the cleaning block 20, and the outer wall of the cleaning ball 21 is provided with a groove, and the spring B23 is connected to the outside of the support rod 22, and the spring B23 is connected to the outer wall of the movable ring 2. Because the cleaning block 20 fits against the outer wall of the pipeline, the cleaning ball 21 will also fit against the outer wall of the pipeline. Therefore, when the movable ring 2 rotates to drive the cleaning block 20 to rotate, the cleaning ball 21 will rub against the outer wall of the pipeline, thereby rotating. When the cleaning ball 21 rotates, part of the protective liquid will be brought out through the groove on the outer wall of the cleaning ball 21 and smeared on the outer wall of the pipeline, thereby providing preliminary protection for the outer wall of the pipeline to prevent corrosion of the pipeline wall after the pipeline has been left unused for a long time after inspection or during transportation, thereby further improving the protection of the pipeline, preventing danger caused by corrosion of the pipeline wall during subsequent use, reducing the service life, and also improving the accuracy of the inspection.

[0137] The working principle and beneficial effects of the above technical solution are:

[0138] The staff places the welded pipeline at the center of the movable ring 2. When using the equipment, the motor 6 drives the rotating shaft 7 to rotate. When the rotating shaft 7 rotates, the gear is fixedly connected to the rotating shaft 7, which will drive the gear to rotate synchronously. When the gear rotates, it will drive the rack 3 to rotate synchronously. Because the movable ring 2 is movably connected, and the rack 3 is fixedly connected to the movable ring 2, when the gear drives the rack 3 to rotate, it will drive the movable ring 2 to rotate; after placing the pipeline inside the movable ring 2, the staff rotates the positioning block to place the ultrasonic detection ring 4 on the outside of the pipeline. The positioning block can be rotated to any angle and then locked; then by rotating the threaded rod 5, the distance between the ultrasonic detection ring 4 and the pipeline is adjusted. The ultrasonic detection ring 4 contacts the outer wall of the pipeline and maintains a stable relative position, thereby detecting cracks inside the pipeline through ultrasound, and also detecting whether there is air leakage at the welding point to prevent accidents during later use; as the pipeline rotates and feeds, all positions of the pipeline are fully detected to reduce the situation of missed detection or insufficient detection accuracy;

[0139] When the movable ring 2 rotates, it will drive multiple groups of cleaning blocks 20 to rotate synchronously. When the cleaning blocks 20 rotate, since the cleaning blocks 20 fit against the outer wall of the pipeline, the cleaning blocks 20 clean the outer wall of the pipeline to prevent stains attached to the outer wall of the pipeline during welding from corroding the pipeline, thereby affecting subsequent use; the pressure sensor on the cleaning block 20 is used to detect the force values ​​of the pipeline in various directions.

[0140] Because the cleaning block 20 fits against the outer wall of the pipeline, the cleaning ball 21 will also fit against the outer wall of the pipeline. Therefore, when the movable ring 2 rotates to drive the cleaning block 20 to rotate, the cleaning ball 21 will rub against the outer wall of the pipeline, thereby rotating. When the cleaning ball 21 rotates, part of the protective liquid will be brought out through the groove on the outer wall of the cleaning ball 21 and smeared on the outer wall of the pipeline, thereby providing preliminary protection for the outer wall of the pipeline to prevent corrosion of the pipeline wall after the pipeline has been left unused for a long time after inspection or during transportation, thereby further improving the protection of the pipeline, preventing danger caused by corrosion of the pipeline wall during subsequent use, reducing the service life, and also improving the accuracy of the inspection.

[0141] When the rotating shaft 7 rotates, the pulley A8 will be driven to rotate synchronously. When the pulley A8 rotates, the two sets of pulleys B10 on both sides will be driven to rotate synchronously through the two sets of belts 9. When the two sets of pulleys B10 rotate, they will synchronously drive the two sets of reciprocating screws 11 to rotate. When the reciprocating screw 11 rotates, it will drive the piston 12 to reciprocate, so that when the piston 12 reciprocates, it will enter the inside of the intake pipe 13. At the same time, because the inner diameter of the piston 12 matches the inner diameter of the intake pipe 13, when the piston 12 moves inside the intake pipe 13, it will squeeze the air pressure to gradually enter the rear end of the intake pipe 13. After the air pressure gradually enters the rear end of the intake pipe 13, it will enter the air pressure valve 15 through the connecting pipe 14. The air pressure valve 15 is provided with a valve at the upper end thereof, and the valve will be automatically pushed open when a certain pressure value is reached, so that the air pressure will quickly enter the inside of the guide tube 17 through the connecting pipe 14 at the upper end of the air pressure valve 15. When the air pressure quickly enters the inside of the guide tube 17, the movable block 18 will be quickly pushed out, so that the movable block 18 will knock on the welding and heat-stressed parts of the outer wall of the pipeline, so that the weld metal will produce plastic deformation, thereby offsetting part of the welding stress, effectively reducing the welding stress concentration, and improving the density and strength of the weld. After the guide tube 17 is ejected, the air pressure will be released through several groups of empty grooves on the outer wall. After the pressure is released, the movable block 18 will automatically reset to the inside of the guide tube 17 through the force of the spring A19.
