Description

Technical Field

[0001] This utility model relates to the field of steel pipe flaw detection technology, specifically to an auxiliary material feeding mechanism for steel pipe flaw detection. Background Technology

[0002] Before steel pipe manufacturers ship their products, they must conduct flaw detection tests to ensure the quality of the pipes. Commonly used flaw detection methods include eddy current testing and ultrasonic testing. Eddy current testing is characterized by its fast detection speed, no need for coupling with the workpiece surface, and high detection sensitivity. However, eddy current testing can only detect the surface or near-surface of the steel pipe and cannot detect the internal condition of some thick-walled steel pipes. Ultrasonic testing, on the other hand, requires more stringent conditions but can detect the internal condition of thick-walled steel pipes, further ensuring the quality of the steel pipes. Therefore, many manufacturers now use a combination of the two flaw detection methods to conduct flaw detection on steel pipes, ensuring the quality of the steel pipes. After the inspection is completed, the pipes need to be cut into blanks for subsequent processing.

[0003] Chinese Utility Model Patent Publication No. CN205114413U discloses a steel pipe flaw detection and unloading mechanism. The specification of this mechanism includes a loading rack and a conveyor table. The loading rack includes a platform portion away from the conveyor table and an inclined portion close to the conveyor table. The inclined portion is provided with multiple inclined guide rails connected to the platform portion and extending above the conveyor table. The inclined guide rails are rotatably connected to the top of a column on the inclined portion near the conveyor table. A limiting block is provided at the end of the inclined guide rail near the conveyor table. This mechanism enables automated loading of steel pipes and efficient removal of defective steel pipes found on the loading rack, ensuring the efficiency of the entire loading process. However, this steel pipe flaw detection and unloading mechanism is not convenient for limiting and lifting during unloading, which can easily lead to jamming. Furthermore, it is not convenient for horizontal movement of the steel pipes, requiring manual intervention, resulting in poor unloading efficiency. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an auxiliary unloading mechanism for steel pipe flaw detection. It can effectively solve the problems in the prior art, such as the inconvenience of limiting and lifting the pipe, which leads to jamming during unloading, and the inconvenience of horizontal movement of the steel pipe, which requires the intervention of the operator and results in poor unloading efficiency.

[0005] The technical solution adopted by this utility model is: an auxiliary feeding mechanism for steel pipe flaw detection, including a main frame, a flaw detection mechanism, a top frame and a fixed frame. A movable component is fixedly installed at the end of the top frame away from the main frame. A conveyor is fixedly installed at the end of the main frame away from the top frame. A fixed frame and a material blocking component are fixedly installed at the inner edge of the fixed frame. The conveyor, the fixed frame and the material blocking component are on the same horizontal line. A feeding component is fixedly installed at the end of the fixed frame away from the main frame.

[0006] The moving component includes a drive motor, a fixed base, a moving beam, and a conveying steel pipe. A slider is fixedly installed at the end of the moving beam away from the fixed base. A slide rail is fixedly installed on the top frame. A connecting frame and a hook are fixedly installed at the end of the moving beam away from the fixed base.

[0007] The feeding assembly includes a second moving motor. An mounting base, a limiting base, and a lifting cylinder are fixedly installed along the inner edge of the fixed frame. A top plate is fixedly installed at the output end of the lifting cylinder.

[0008] Preferably, a drive wheel is fixedly installed at the output end of the drive motor, a drive belt is provided at the end of the drive wheel away from the drive motor, a driven wheel is provided at the end of the drive belt away from the drive wheel, a drive screw is fixedly installed at the inner edge of the driven wheel, the fixed seat and the moving beam are fixedly installed, and the drive screw and the moving beam are threadedly connected.

[0009] Through the above technical solution, and through the design of the first transmission motor, when it is necessary to unload materials, the first transmission motor can drive the first drive wheel, which in turn drives the first driven wheel and the first transmission screw to rotate via the first transmission belt. The transmission screw is threadedly engaged with the moving beam, which converts the rotational motion into the linear translation of the moving beam, making it easier to move the conveying steel pipe on the hook.

[0010] Preferably, the slide rail and the slider are slidably connected, and there are two identical slide rails and sliders, which are symmetrically distributed about the center line of the moving beam.

[0011] With the above technical solution, when the transmission screw is in motion, the two symmetrically distributed slide rails and the slider can slide together to guide the moving beam, improve the stability of the moving beam, and prevent the conveying steel pipe from shaking or falling off during the transfer process.

[0012] Preferably, there are two identical connecting frames and hooks, which are distributed at equal intervals, and the cross-section of the hooks is in the shape of a "J".

[0013] The above technical solution uses the arc-shaped contour of the J-hook to fit the outer wall of the conveying steel pipe, which can stably hook the steel pipe without damaging the surface. In addition, the equidistant distribution design can keep the center of gravity of the steel pipe in the middle of the two hooks, ensuring balance and no tilting during transfer. It can be adapted to steel pipes of different diameters, improve the versatility of the mechanism, and avoid the steel pipe from rotating or slipping due to single-point suspension.

[0014] Preferably, a drive wheel is fixedly installed at the output end of the second mobile motor, and a driven wheel is meshed at the other end of the drive wheel away from the second mobile motor. A rotating rod is fixedly installed at the inner edge of the driven wheel, and the rotating rod is in contact with the conveying steel pipe. The top plate is in contact with the conveying steel pipe.

[0015] Through the above technical solution, the active wheel two and the driven wheel two mesh to drive the rotating rod to rotate. The friction force pushes the conveyed steel pipe to move towards the storage rack. With the addition of the lifting cylinder to extend and retract, the height of the top plate can be adjusted to accommodate steel pipes of different thicknesses or to connect with the height of the conveyor. This can realize the conveying of steel pipes, reduce manual intervention, and the cylinder lifting can adjust the height of the steel pipe so that it can connect with the discharge baffle and guide plate to avoid material jamming.

[0016] Preferably, the material blocking assembly includes a mounting plate, on which a guide rail is fixedly mounted. A guide seat is slidably connected to the end of the guide rail away from the mounting plate, and a rotary cylinder is fixedly mounted to the end of the guide seat near the material feeding assembly.

[0017] Through the above technical solution, by designing a rotary cylinder, when feeding or conveying steel pipes of different lengths, the rotary cylinder can slide on the guide rail via the guide seat, and then bring the rotary cylinder close to the conveying steel pipe, thereby facilitating rapid feeding.

[0018] Preferably, a feeding baffle and a storage rack are fixedly installed at the end of the fixed frame away from the main frame, and a guide plate is fixedly installed at the end of the storage rack near the feeding baffle. The guide plate has a U-shaped cross-section.

[0019] With the above technical solution, the material discharge baffle and storage rack can guide the conveying steel pipe to fall to the storage rack during material discharge, which facilitates rapid material discharge, reduces the number of work steps for workers, and improves production efficiency.

[0020] Compared with the prior art, this utility model provides an auxiliary feeding mechanism for steel pipe flaw detection, which has the following beneficial effects:

[0021] 1. This auxiliary feeding mechanism for steel pipe flaw detection drives the rotating rod to rotate through the meshing of the second driving wheel and the second driven wheel. The friction force pushes the conveyed steel pipe to move towards the storage rack. With the addition of a lifting cylinder that can extend and retract to adjust the height of the top plate, it can adapt to steel pipes of different thicknesses or connect with the height of the conveyor. This enables the conveying of steel pipes, reduces manual intervention, and the cylinder lifting can adjust the height of the steel pipe so that it can align with the feeding baffle and guide plate to avoid jamming.

[0022] 2. The auxiliary unloading mechanism for steel pipe flaw detection, through the design of the moving component, can easily lift the inspected steel pipe and then place it on the conveyor for movement. With the help of the unloading baffle and storage rack, when unloading, the unloading baffle can guide the conveyed steel pipe to fall to the storage rack, which can facilitate rapid unloading, reduce the number of work steps for workers, and improve production efficiency.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1: As Figure 1-6 As shown, the present invention provides an auxiliary feeding mechanism for steel pipe flaw detection, including a main frame 1, a flaw detection mechanism 2, a top frame 3 and a fixed frame 6. A movable component 4 is fixedly installed at the end of the top frame 3 away from the main frame 1. A conveyor 5 is fixedly installed at the end of the main frame 1 away from the top frame 3. A fixed frame 6 and a material blocking component 11 are fixedly installed at the inner edge of the fixed frame 6. The conveyor 5, the fixed frame 6 and the material blocking component 11 are on the same horizontal line. A feeding component 7 is fixedly installed at the end of the fixed frame 6 away from the main frame 1.

[0032] The moving component 4 includes a drive motor 401, a fixed base 406, a moving beam 407 and a conveying steel pipe 412. A slider 408 is fixedly installed on the end of the moving beam 407 away from the fixed base 406. A slide rail 409 is fixedly installed on the top frame 3. A connecting frame 410 and a hook 411 are fixedly installed on the end of the moving beam 407 away from the fixed base 406.

[0033] The unloading assembly 7 includes a moving motor 701, and a mounting base 705, a limit seat 706 and a lifting cylinder 707 are fixedly installed on the inner edge of the fixed frame 6. A top plate 708 is fixedly installed on the output end of the lifting cylinder 707.

[0034] Specifically, a drive wheel 402 is fixedly installed at the output end of the drive motor 401. A transmission belt 403 is provided at the end of the drive wheel 402 away from the drive motor 401. A driven wheel 404 is provided at the end of the transmission belt 403 away from the drive wheel 402. A transmission screw 405 is fixedly installed at the inner edge of the driven wheel 404. The fixed seat 406 and the moving beam 407 are fixedly installed. The transmission screw 405 and the moving beam 407 are threadedly connected. The advantage is that, through the design of the drive motor 401, when material needs to be unloaded, the drive wheel 402 can be driven by the drive motor 401, which in turn drives the driven wheel 404 and the transmission screw 405 to rotate via the transmission belt 403. The transmission screw 405 and the moving beam 407 are threadedly engaged, converting the rotational motion into the linear translation of the moving beam 407, which facilitates the movement of the conveying steel pipe 412 on the hook 411.

[0035] Specifically, the slide rail 409 and the slider 408 are slidably connected. There are two identical slide rails 409 and sliders 408. The two slide rails 409 and sliders 408 are symmetrically distributed about the center line of the moving beam 407. The advantage is that when the transmission screw 405 is in operation, the two symmetrically distributed slide rails 409 and sliders 408 can slide together, which can guide the moving beam 407, improve the stability of the movement of the moving beam 407, and prevent the conveying steel pipe 412 from shaking or falling off during the transfer process.

[0036] Specifically, there are two identical connecting frames 410 and hooks 411, and the two connecting frames 410 and hooks 411 are distributed at equal intervals. The cross-section of hook 411 is a "J" shaped structure. The advantage is that the arc contour of the J-shaped hook fits the outer wall of the conveying steel pipe 412, which can stably hook the steel pipe without damaging the surface. In addition, with the design of equal distribution, the center of gravity of the steel pipe can be located in the middle of the two hooks 411, ensuring balance and no tilting during transfer. It can be adapted to steel pipes of different diameters, improve the versatility of the mechanism, and avoid the rotation or slippage of the steel pipe caused by single-point suspension.

[0037] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0038] Specifically, a drive wheel 702 is fixedly installed at the output end of the second mobile motor 701. The other end of the drive wheel 702, away from the second mobile motor 701, is meshed with a driven wheel 703. A rotating rod 704 is fixedly installed on the inner edge of the driven wheel 703. The rotating rod 704 is in contact with the conveying steel pipe 412, and the top plate 708 is in contact with the conveying steel pipe 412. The advantage is that the drive wheel 702 and the driven wheel 703 mesh and drive the rotating rod 704 to rotate. The friction force pushes the conveying steel pipe 412 to move towards the storage rack 9. With the extension and retraction of the lifting cylinder 707, the height of the top plate 708 can be adjusted to adapt to steel pipes of different thicknesses or to connect with the height of the conveyor 5. This can realize the conveying of steel pipes, reduce manual intervention, and the cylinder lifting can adjust the height of the steel pipe so that it can connect with the discharge baffle 8 and the guide plate 10 to avoid material jamming.

[0039] Specifically, the material blocking assembly 11 includes a mounting plate 1101, on which a guide rail 1102 is fixedly mounted. A guide seat 1103 is slidably connected to one end of the guide rail 1102 away from the mounting plate 1101. A rotary cylinder 1104 is fixedly mounted on one end of the guide seat 1103 near the material feeding assembly 7. The advantage is that, through the design of the rotary cylinder 1104, when feeding or conveying steel pipes 412 of different lengths, the guide seat 1103 can slide on the guide rail 1102, and then the rotary cylinder 1104 can be brought close to the conveying steel pipe 412, thereby facilitating rapid feeding.

[0040] Specifically, a feeding baffle 8 and a storage rack 9 are fixedly installed at the end of the fixed frame 6 away from the main frame 1. A guide plate 10 is fixedly installed at the end of the storage rack 9 near the feeding baffle 8. The guide plate 10 has a U-shaped cross-section. The advantage is that when feeding, the feeding baffle 8 can guide the conveying steel pipe 412 to fall to the storage rack 9, which facilitates rapid feeding, reduces the number of work steps for workers, and improves production efficiency.

[0041] Working Principle: During use, the design of the drive motor 401 allows the drive wheel 402 to rotate via the drive belt 403 when material needs to be unloaded. The drive wheel 404 and the drive screw 405 rotate through the drive belt 403. The drive screw 405 is threaded into the moving beam 407, converting the rotational motion into linear translation of the moving beam 407. This facilitates the movement of the conveying steel pipe 412 on the hook 411. When the drive screw 405 is in operation, the two symmetrically distributed slide rails 409 and sliders 408 slide together, guiding the moving beam 407 and improving its stability. This prevents the conveying steel pipe 412 from shaking or falling off during transport. The J-shaped hook's arc contour fits the outer wall of the conveying steel pipe 412, stably hooking it without damaging the surface. Combined with the equidistant distribution design, this ensures the steel pipe... The center of gravity is located between the two hooks 411, ensuring balance and preventing tilting during transfer. It can accommodate steel pipes of different diameters, improving the versatility of the mechanism and avoiding rotation or slippage of the steel pipe caused by single-point suspension. Through the meshing transmission of the second drive wheel 702 and the second driven wheel 703, the rotating rod 704 is driven to rotate. The friction force pushes the conveyed steel pipe 412 to move towards the storage rack 9. With the extension and retraction of the lifting cylinder 707, the height of the top plate 708 can be adjusted to accommodate steel pipes of different thicknesses or to connect with the height of the conveyor 5. This enables the conveying of steel pipes, reduces manual intervention, and the cylinder lifting can adjust the height of the steel pipe so that it can connect with the discharge baffle 8 and the guide plate 10 to avoid jamming. Through the discharge baffle 8 and the storage rack 9, when unloading, the conveyed steel pipe 412 can be guided by the discharge baffle 8 to fall to the storage rack 9, which can facilitate rapid unloading, reduce the number of work steps for workers, and improve production efficiency.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
