Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to a flaw detection device for inspecting material pipes. Background Technology

[0002] Seamless steel pipes can be used for material conveying. They are steel pipes without seams on their surface. According to the production method, seamless steel pipes are divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, and jacking pipes. According to the shape of the cross-section, seamless steel pipes are divided into round and irregular shapes. They are mainly used in oil and geological drilling pipes, cracking pipes for petrochemicals, boiler tubes, bearing tubes, and high-precision structural steel pipes for automobiles, tractors, and aviation.

[0003] After seamless steel pipes are manufactured, the inner wall of the pipe will have some protrusions and unevenness due to the extrusion device. If wrinkles or burrs appear on the inner wall of the pipe during the extrusion process, these defects will greatly affect the quality of the pipe. Therefore, it is necessary to perform flaw detection on the surface of the pipe. If the inspection box detects defects on the surface of the pipe, it is necessary to conduct further manual re-judgment. Since the inspection position of the pipe is inside the inspection box, the equipment needs to be stopped or the pipe needs to be marked before the re-judgment is carried out. Then the defect position of the pipe needs to be moved out of the inspection box before manual re-judgment. The re-judgment process is quite troublesome. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a flaw detection device for steel pipe inspection. By incorporating a braking component, the device can move the defective location of the steel pipe outside the inspection box while simultaneously stopping the movement of the steel pipe, facilitating manual re-evaluation. This invention aims to solve the problems in the prior art.

[0005] To achieve the above-mentioned technical objectives, the specific technical solution of the present invention is as follows: The present invention proposes a flaw detection device for tube inspection, comprising: a detection box, the detection box having a detection hole through which the tube passes, and a controller installed on the detection box; a detection component installed inside the detection hole, the detection component being used for flaw detection on the surface of the tube; a drive component for driving the tube to move; and a braking component for stopping the tube's movement; the braking component includes a movable frame, the movable frame being symmetrically connected with a pair of rotating shafts, the rotating shafts being connected with clamping wheels, the two clamping wheels being respectively located on the upper and lower sides of the tube and clamping the tube, the rotation of the rotating shafts changing the orientation of the clamping wheels; wherein, the orientation of the clamping wheels is their rolling direction; when the detection component detects damage on the surface of the tube, the rotating shafts rotate, driving the clamping wheels to rotate, so that the orientation of the clamping wheels is perpendicular to the axial direction of the tube, and as the tube continues to move, it drives the movable frame to move away from the detection box.

[0006] As a preferred embodiment of the present invention, a movable drive frame is connected to the movable frame, a pair of racks are fixedly connected to the drive frame, a gear meshing with the racks is fixedly connected to the rotating shaft, and a limiting frame that is slidably connected to the racks is fixedly connected to the movable frame.

[0007] As a preferred embodiment of the present invention, a servo motor is installed on the movable frame to drive the drive frame to move. A lead screw is connected to the servo motor and is threadedly connected to the drive frame. When the lead screw rotates, it drives the drive frame to move. The gear is driven to rotate through the rack and pinion to change the orientation of the clamping wheel.

[0008] As a preferred embodiment of the present invention, a pair of sliding rods are movably connected to the movable frame. One end of the sliding rod is fixedly connected to the detection box, and the other end of the sliding rod is fixedly connected to a stop block. A cylindrical spring is connected to the surface of the sliding rod and is located between the stop block and the movable frame.

[0009] As a preferred embodiment of the present invention, the driving assembly includes: a rotating frame, on which a drive motor is mounted, and a drive wheel is connected to the drive motor for driving the material tube forward; and a fixed frame, fixedly connected to the detection box, with an elastic element fixedly connected between the fixed frame and the rotating frame.

[0010] As a preferred embodiment of the present invention, a first support is fixedly connected to the movable frame, and a roller is connected to the first support. A second support is fixedly connected to the rotating frame, and a guide rail that cooperates with the roller is fixedly connected to the second support. When the roller moves away from the detection box along the guide rail, it drives the rotating frame to rotate horizontally, and the drive wheel separates from the surface of the material tube.

[0011] As a preferred embodiment of the present invention, the detection assembly includes a detection ring rotatably connected inside the detection hole, a plurality of third supports are fixedly connected to the detection ring, and a detection probe is fixedly connected to the third support. The detection probe is used for flaw detection on the surface of the material tube.

[0012] As a preferred embodiment of the present invention, the detection component includes: a connecting frame, which is fixedly connected to the detection box, a first rotating rod rotatably connected to the connecting frame, and a conveying wheel coaxially fixedly connected to the first rotating rod, the conveying wheel contacting the surface of the material tube.

[0013] As a preferred embodiment of the present invention, a second rotating rod is rotatably connected to the connecting frame. The second rotating rod is perpendicular to the first rotating rod, and a driving bevel gear is fixedly connected to one end of the first rotating rod. A driven bevel gear that meshes with the driving bevel gear is fixedly connected to one end of the second rotating rod, and a rotating seat is fixedly connected to the other end of the second rotating rod for driving the detection ring to rotate.

[0014] As a preferred embodiment of the present invention, the surface of the rotating seat is provided with a spiral ridge, and the inner surface of the detection ring is provided with a plurality of grooves that cooperate with the ridge.

[0015] The beneficial effects of this invention are as follows: This invention incorporates a braking component and a driving component. When the detection component detects a defect on the surface of the tube, the braking component clamps the tube, and then the tube moves forward along with the moving frame, moving the defect location out of the detection box. Simultaneously, the driving component separates from the tube, and the tube stops moving, facilitating timely re-judgment of the defect location.

[0016] The detection component of this invention drives the rotating seat to rotate by the rotation of the conveyor wheel. When the rotating seat rotates, it drives the detection ring to rotate, so that the detection ring moves in a circle around the material tube as the tube moves forward, thereby detecting the material tube from all angles.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] It should be noted that flaw detection is a process that starts with straightening and enters online eddy current and ultrasonic testing, marking and sorting out non-conforming areas, removing blind spots online, and finally checking dimensions and packaging. It mainly reflects the automation of the entire process.

[0025] Example: This example discloses a flaw detection device for inspecting material pipes, such as... Figures 1-5 As shown, it includes: a detection box 1, which has a detection hole 101 through which the material tube passes, and a controller 5 installed on the detection box 1. The controller 5 is used to control the operation of the braking assembly 3; a detection assembly 4, which is installed in the detection hole 101 and is used to detect flaws on the surface of the material tube; a drive assembly 2, which is used to drive the material tube to move; and a braking assembly 3, which is used to stop the movement of the material tube. When the detection assembly 4 detects damage on the surface of the material tube, the controller 5 controls the braking assembly 3 to operate, and the material tube stops being conveyed forward, which facilitates the re-judgment of the material tube.

[0026] Among them, such as Figure 2 As shown, the detection assembly 4 includes a detection ring 49, rotatably connected within the detection hole 101. Multiple third supports 411 are fixedly connected to the detection ring 49, and detection probes 412 are fixedly connected to each third support 411. The number of detection probes 412 is 3-4, and the detection probes 412 are used for surface flaw detection of the material tube. The detection assembly 4 also includes a connecting frame 41, which is fixedly connected to the detection box 1. A first rotating rod 44 is rotatably connected to the connecting frame 41, and a conveying wheel 42 is coaxially fixedly connected to the first rotating rod 44. The conveying wheel 42 contacts the surface of the material tube, and the material tube rotates when it moves forward. A second rotating rod 45 is rotatably connected to the connecting frame 41, and the second rotating rod 45 is perpendicular to the first rotating rod 44. One end of the first rotating rod 44 is fixedly connected to... The active bevel gear 43 and the second rotating rod 45 are fixedly connected at one end to a driven bevel gear 46 that meshes with the active bevel gear 43. The other end of the second rotating rod 45 is fixedly connected to a rotating seat 47, which is used to drive the detection ring 49 to rotate. The surface of the rotating seat 47 is provided with a spiral ridge 48, and the inner surface of the detection ring 49 is provided with several grooves 410 that cooperate with the ridge 48, so that the rotating seat 47 can drive the detection ring 49 to rotate when it rotates. During the forward movement of the material tube, the conveyor wheel 42 is driven to rotate. When the conveyor wheel 42 rotates, it drives the first rotating rod 44 to rotate. The first rotating rod 44 drives the second rotating rod 45 to rotate, which in turn drives the rotating seat 47 to rotate. When the rotating seat 47 rotates, it drives the detection ring 49 to rotate, which in turn causes the detection probe 412 to rotate around the circumference of the material tube, so as to comprehensively detect the material tube.

[0027] like Figure 3 As shown, the drive assembly 2 includes: a rotating frame 21, which is rotatably connected to the detection box 1, a drive motor 22 is mounted on the rotating frame 21, and a drive wheel 23 is connected to the drive motor 22 for driving the material tube forward; and a fixed frame 24, which is fixedly connected to the detection box 1, and an elastic element 25 is fixedly connected between the fixed frame 24 and the rotating frame 21. The elastic element 25 applies elastic force to the rotating frame 21 so that the drive wheel 23 keeps in contact with the surface of the material tube.

[0028] like Figures 4-5 As shown, the braking assembly 3 includes a movable frame 31, on which a pair of rotating shafts 36 are symmetrically connected. Clamping wheels 37 are connected to the rotating shafts 36, which are respectively located on the upper and lower sides of the material tube and clamp the material tube. When the material tube moves, the clamping wheels 37 rotate on the surface of the material tube, and the rotation of the rotating shafts 36 can change the orientation of the clamping wheels 37; the orientation of the clamping wheels 37 is its rolling direction. When the detection assembly 4 detects damage on the surface of the material tube, the rotating shafts 36 rotate, causing the clamping wheels 37 to rotate, making the orientation of the clamping wheels 37 perpendicular to the axial direction of the material tube, increasing the friction between the clamping wheels 37 and the material tube. As the material tube continues to move, it drives the movable frame 31 to move away from the detection box 1.

[0029] The movable frame 31 is connected to a movable drive frame 35. A pair of racks 39 are fixedly connected to the drive frame 35. A gear 38 that meshes with the racks 39 is fixedly connected to the rotating shaft 36. A limit frame 310 that slides with the racks 39 is fixedly connected to the movable frame 31. A servo motor 312 is installed on the movable frame 31 to drive the drive frame 35 to move. A lead screw 311 is connected to the servo motor 312. The lead screw 311 is threadedly connected to the drive frame 35. When the detection component 4 detects damage on the surface of the material tube, the controller 5 controls the servo motor 312 to start. The servo motor 312 drives the lead screw 311 to rotate. When the lead screw 311 rotates, it drives the drive frame 35 to move. The racks 39 drive the gear 38 to rotate 90°, changing the orientation of the clamping wheel 37. When the material tube continues to move forward, it will drive the movable frame 31 to move together.

[0030] Preferably, a pair of slide rods 32 are movably connected to the movable frame 31. One end of the slide rod 32 is fixedly connected to the detection box 1, and the other end of the slide rod 32 is fixedly connected to a stop block 33. A cylindrical spring 34 is connected to the surface of the slide rod 32. The cylindrical spring 34 is located between the stop block 33 and the movable frame 31. When the movable frame 31 moves away from the detection box 1, the cylindrical spring 34 is compressed by force, and the cylindrical spring 34 plays the role of resetting the movable frame 31.

[0031] Preferably, a first support 313 is fixedly connected to the movable frame 31, and a roller 314 is connected to the first support 313. A second support 26 is fixedly connected to the rotating frame 21, and a guide rail 27 that cooperates with the roller 314 is fixedly connected to the second support 26. The guide rail 27 is in the shape of a right trapezoid. When the roller 314 moves away from the detection box 1 along the guide rail 27, it drives the rotating frame 21 to rotate horizontally away from the material tube. The drive wheel 23 separates from the surface of the material tube, and the drive assembly 2 no longer drives the material tube to move, and the material tube stops running.

[0032] In practice: During the inspection process, drive component 2 moves the tube forward, and inspection component 4 rotates around the tube to perform a comprehensive inspection. When inspection component 4 detects a defect on the tube surface, inspection probe 412 sends a signal to controller 5. Controller 5 then starts servo motor 312, which drives lead screw 311 to rotate, moving drive frame 35. Rack 39 drives gear 38 to rotate, which in turn drives rotating shaft 36 to rotate, causing clamping wheel 37 to rotate horizontally by 90°, making clamping wheel 37 perpendicular to the tube axis. This greatly increases the friction between the tube and clamping wheel 37. As the tube continues to move forward, it drives the entire moving frame 31. The material tube moves away from the inspection box 1, causing the defect location to move outside the inspection box 1. The cylindrical spring 34 is compressed, and at the same time, the roller 314 rolls along the guide rail 27, driving the rotating frame 21 to rotate away from the material tube. The drive wheel 23 separates from the material tube, and the material tube stops moving. The inspection personnel re-judge the defect location of the material tube. After the re-judgment is completed, the controller 5 controls the servo motor 312 to rotate in the opposite direction, changing the orientation of the clamping wheel 37 to be parallel to the axis of the material tube. The moving frame 31 moves towards the inspection box 1 under the elastic force of the cylindrical spring 34, returning to its original position. At the same time, the rotating frame 21 rotates towards the material tube, and the drive wheel 23 contacts the material tube again, continuing to drive the material tube forward.
