Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to a flaw detection equipment for material pipe detection. Background Art

[0002] Seamless steel pipes can be used for material transportation. There are no seams on the surface of the steel pipes. 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. At the same time, according to the shape of the cross-section, seamless steel pipes are divided into round and special-shaped ones. They are mainly used in petroleum geological drilling pipes, cracking pipes for petrochemicals, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation.

[0003] After the seamless steel pipe is manufactured, the inner wall of the steel pipe will be affected by the extrusion device, and there will be more or less bulges and unevenness on the inner wall of the steel pipe. Once the inner wall of the steel pipe is affected by the extrusion end during the extrusion process and wrinkles or burrs appear, these defects will have a great impact on the quality of the steel pipe. Therefore, it is necessary to perform flaw detection on the surface of the steel pipe. If the detection box detects surface defects of the steel pipe, manual re-evaluation is required. Since the steel pipe detection position is inside the detection box, the equipment needs to be stopped or the steel pipe needs to be marked during the re-evaluation, and then the defective position of the steel pipe needs to be moved out of the detection box for manual re-evaluation. The re-evaluation operation process is relatively cumbersome. Summary of the Invention

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described 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.

[0025] It should be noted that flaw detection is a process that starts with straightening, then enters online eddy current and ultrasonic testing, marks and sorts unqualified parts, removes blind areas online, and finally checks and packages the dimensions, which mainly reflects the automation of the entire process.

[0026] Example: This embodiment discloses a flaw detection device for material pipe detection. Figure 1-Figure 5 As shown, it includes: a detection box 1, which is provided with a detection hole 101 for the material pipe to pass through, and a controller 5 is installed on the detection box 1, and the controller 5 is used to control the operation of the brake component 3; a detection component 4, which is installed in the detection hole 101 and is used to detect flaws on the surface of the material pipe; a driving component 2, which is used to drive the material pipe to move; and a brake component 3, which is used to stop the movement of the material pipe. When the detection component 4 detects damage on the surface of the material pipe, the controller 5 controls the brake component 3 to operate, and the material pipe stops conveying forward, so that the material pipe can be re-judged.

[0027] Among them, such as Figure 2 As shown, the detection component 4 includes a detection ring 49, which is rotatably connected in the detection hole 101, and a plurality of third brackets 411 are fixedly connected to the detection ring 49, and a detection probe 412 is fixedly connected to the third bracket 411. The number of the detection probes 412 is 3-4, and the detection probe 412 is used for flaw detection on the surface of the material pipe; the detection component 4 also includes: a connecting frame 41, the connecting frame 41 is fixedly connected to the detection box 1, and 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 pipe, and the conveying wheel 42 is driven to rotate when the material pipe 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, and one end of the first rotating rod 44 is fixedly connected to The driving bevel gear 43 and the second rotating rod 45 are fixedly connected at one end with a driven bevel gear 46 meshing with the driving bevel gear 43, and the other end of the second rotating rod 45 is fixedly connected with a rotating seat 47 for driving the detection ring 49 to rotate; the surface of the rotating seat 47 is provided with a spiral convex strip 48, and the inner surface of the detection ring 49 is provided with a plurality of grooves 410 that cooperate with the convex strip 48, so that the rotating seat 47 can drive the detection ring 49 to rotate when it rotates; in the process of the material tube moving forward, it drives the conveying wheel 42 to rotate, and when the conveying wheel 42 rotates, it drives the first rotating rod 44 to rotate, and the first rotating rod 44 drives the second rotating rod 45 to rotate, thereby driving the rotating seat 47 to rotate, and when the rotating seat 47 rotates, it drives the detection ring 49 to rotate, thereby causing the detection probe 412 to rotate around the circumference of the material tube, and comprehensively detect the material tube.

[0028] like Figure 3 As shown, the driving assembly 2 includes: a rotating frame 21, which is rotatably connected to the detection box 1, and a driving motor 22 is installed on the rotating frame 21. The driving motor 22 is connected to a driving wheel 23 for driving the material tube to be transported forward; a fixed frame 24, which is fixedly connected to the detection box 1, and an elastic member 25 is fixedly connected between the fixed frame 24 and the rotating frame 21. The elastic member 25 applies elastic force to the rotating frame 21, so that the driving wheel 23 maintains contact with the surface of the material tube.

[0029] like Figure 4-Figure 5 As shown, the brake assembly 3 includes a movable frame 31, which is symmetrically connected to a pair of rotating shafts 36, and a clamping wheel 37 is connected to the rotating shaft 36. The two clamping wheels 37 are respectively arranged 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 direction of the clamping wheels 37 can be changed when the rotating shaft 36 rotates; wherein, the direction of the clamping wheels 37 is its rolling direction; when the detection assembly 4 detects that the surface of the material tube is damaged, the rotating shaft 36 rotates to drive the clamping wheels 37 to rotate, so that the direction of the clamping wheels 37 is perpendicular to the axial direction of the material tube, thereby increasing the friction between the clamping wheels 37 and the material tube. When the material tube continues to move, it drives the movable frame 31 to move away from the detection box 1.

[0030] Among them, the movable driving frame 35 is connected to the moving frame 31, and a pair of racks 39 are fixedly connected to the driving frame 35. A gear 38 meshing with the rack 39 is fixedly connected to the rotating shaft 36, and a limit frame 310 slidingly connected to the rack 39 is fixedly connected to the moving frame 31; a servo motor 312 is installed on the moving frame 31 to drive the driving frame 35 to move, and the servo motor 312 is connected to the screw rod 311, and the screw rod 311 is threadedly connected to the driving 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, and the servo motor 312 drives the screw rod 311 to rotate. When the screw rod 311 rotates, it drives the driving frame 35 to move, and drives the gear 38 to rotate 90° through the rack 39, changing the direction of the clamping wheel 37. When the material tube continues to move forward, it will drive the moving frame 31 to move together.

[0031] Preferably, a pair of slide rods 32 are movably connected to the mobile 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 the stopper 33, and a cylindrical spring 34 is connected to the surface of the slide rod 32. The cylindrical spring 34 is arranged between the stopper 33 and the mobile frame 31. When the mobile frame 31 moves away from the detection box 1, the cylindrical spring 34 is compressed by force, and the cylindrical spring 34 plays a role in resetting the mobile frame 31.

[0032] Preferably, a first bracket 313 is fixedly connected to the movable frame 31, a roller 314 is connected to the first bracket 313, a second bracket 26 is fixedly connected to the rotating frame 21, and a guide rail 27 cooperating with the roller 314 is fixedly connected to the second bracket 26. The guide rail 27 is in the shape of a right-angled trapezoid. When the roller 314 moves along the guide rail 27 away from the detection box 1, it drives the rotating frame 21 to rotate horizontally away from the material pipe, the driving wheel 23 is separated from the surface of the material pipe, the driving assembly 2 no longer drives the material pipe to move, and the material pipe stops running.

[0033] During specific implementation: During the detection process, the driving component 2 drives the material tube to move forward, and the detection component 4 rotates in a circle around the material tube to perform a comprehensive detection on the material tube. When the detection component 4 detects defects on the surface of the material tube, the detection probe 412 sends a signal to the controller 5. The controller 5 controls the servo motor 312 to start, and the servo motor 312 drives the screw rod 311 to rotate, drives the driving frame 35 to move, drives the rack 39 to rotate the gear 38, and drives the rotating shaft 36 to rotate, drives the clamping wheel to rotate horizontally 90 degrees, so that the clamping wheel 37 is perpendicular to the axis of the material tube, which greatly increases the friction between the material tube and the clamping wheel 37. When the material tube continues to move forward, it drives the moving frame 31 as a whole. It moves away from the inspection box 1, so that the defective position of the material tube moves out of 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 driving wheel 23 is separated from the material tube, and the material tube stops moving. The inspection personnel re-judge the defective position 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 direction of the clamping wheel 37 to be parallel to the axial direction of the material tube. The movable frame 31 moves toward the inspection box 1 under the elastic force of the cylindrical spring 34 and returns to its original position. At the same time, the rotating frame 21 rotates toward the material tube, and the driving wheel 23 contacts the material tube again, continuing to drive the material tube forward.
