Description

Technical Field

[0001] This invention relates to the field of detection equipment technology, and in particular to a seamless stainless steel pipe welding defect sensing and detection device. Background Technology

[0002] Seamless stainless steel pipe is an important steel pipe product, widely used in various industrial fields due to its excellent mechanical properties and corrosion resistance. Sensor detection of welding defects in seamless stainless steel pipes is a crucial step in ensuring welding quality and extending pipeline service life. Seamless stainless steel pipes are widely used in petroleum, natural gas, chemical, food, and pharmaceutical industries, thus requiring extremely high welding quality.

[0003] The prior art publication CN222353810U provides an automatic inspection device for stainless steel pipe welds. This device uses a drive unit and a three-jaw wedge chuck to clamp and position the stainless steel pipe, then automatically scans the weld using a laser scanner. A control computer automatically processes and analyzes the data. The entire inspection process requires minimal manual intervention, improving production efficiency. Furthermore, the laser scanners are arranged in a circular array, enabling comprehensive and thorough scanning of the outer wall of the stainless steel pipe, ensuring the accuracy and completeness of weld inspection. In addition, the control computer can judge the weld quality based on the analysis results and issue alarms or notify operators when defects are detected, achieving intelligent inspection and management.

[0004] When using this device, the steel pipes need to be lifted by manual handling or other hoisting equipment before they can be clamped and inspected using a three-jaw chuck. This makes it inconvenient for automatic loading and unloading. Manual handling may bring safety hazards and increase labor intensity, and reduce the overall efficiency of the production line, making it impossible to further improve the level of automation.

[0005] In summary, the existing technology lacks a technology for automatic loading and unloading when sensing and detecting welding defects in seamless stainless steel pipes. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by proposing a seamless stainless steel pipe welding defect sensing and detection device.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a seamless stainless steel pipe welding defect sensing and detection device, comprising a frame, a three-jaw chuck provided on one side of the upper end of the frame, a detection ring seat fixedly connected to the other side of the upper end of the frame, a fixed frame fixedly connected to one side of the frame, a feeding component fixedly connected to the fixed frame, a pre-embedded seat fixedly connected to the bottom end of the fixed frame, a feeding trough fixedly connected through the middle of the frame, and a receiving component symmetrically arranged above the feeding trough.

[0008] Preferably, a hydraulic push rod is fixedly connected to one side of the three-jaw chuck, and the hydraulic push rod is fixedly connected to the frame through it.

[0009] Preferably, the inner wall of the detection ring seat is provided with a plurality of ultrasonic sensors in a ring structure, an electric push rod is fixedly connected to one side of the detection ring seat, an adjustment frame is fixedly connected to the top of the electric push rod, and a support roller is rotatably connected to the adjustment frame.

[0010] Preferably, the fixing frame is arranged with an inclined structure, and a guide plate is fixedly connected to one side of the top of the fixing frame.

[0011] Preferably, the feeding assembly includes a motor, which is fixedly connected to the bottom end of the fixed frame. A lead screw is fixedly connected to the output end of the motor. The lead screw is rotatably connected to the fixed frame. A feeding plate is threadedly connected to the outer wall of the lead screw. A transmission rack is fixedly connected to one side of the feeding plate.

[0012] Preferably, a protective plate is slidably fitted on one side of the inner wall of the embedded base, and a groove is provided at the bottom end of the protective plate. A rotating shaft is rotatably connected through one side of the inner wall of the embedded base. An L-shaped rod is fixedly connected to the top end of the rotating shaft. The outer wall of the top end of the L-shaped rod is slidably fitted with the inner wall of the groove. A universal joint is fixedly connected to the bottom end of the rotating shaft. One end of the universal joint is rotatably connected to the inner wall of the embedded base, and a transmission wheel is fixedly connected to the other end of the universal joint. The transmission wheel is movably meshed with a transmission rack for transmission.

[0013] Preferably, a plurality of rubber strips are fixedly connected to the upper side of the inner wall of the feeding trough, and a baffle is provided at the bottom opening of the feeding trough.

[0014] Preferably, the receiving assembly includes a movable frame, a hydraulic cylinder is fixedly connected to the bottom of the movable frame, the hydraulic cylinder is fixedly connected to the frame through the hydraulic cylinder, and a receiving plate is rotatably connected to the top of the movable frame.

[0015] Preferably, a transmission rod is rotatably connected to the bottom end of the movable frame. Two top rods are fixedly connected to the transmission rod in a symmetrical structure. The other end of the top rod is slidably in contact with one side of the receiving plate. A worm gear is fixedly connected to one end of the transmission rod. A worm is meshed with one side of the worm gear. The worm is rotatably connected to the movable frame. An adjusting wheel is fixedly connected to one end of the worm. A fixed rack is meshed with one side of the adjusting wheel. The fixed rack is fixedly connected to the frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects: By setting up a feeding component, steel pipes on the ground can be automatically transported into the receiving component and fixed by a three-jaw chuck, eliminating the need for manual handling. This reduces the workload of workers, shortens the production cycle, and improves overall production efficiency. At the same time, when the feeding component is retracted and reset, it can automatically close the protective plate on the embedded seat, preventing workers from falling. This not only improves safety but also achieves a steady improvement in product quality by increasing efficiency, saving time, and reducing costs. By setting up the receiving component, the position of the steel pipe can be automatically adjusted so that one end of the steel pipe can be aligned with the clamping center of the three-jaw chuck. Automatic adjustment reduces the operational error caused by manual intervention and improves the consistency of the production process. At the same time, when the receiving component moves to the bottom, the receiving plate can rotate automatically, so that the inspected steel pipe can fall into the unloading chute automatically, simplifying the unloading process of the steel pipe, avoiding additional manual handling and processing, and improving the convenience of operation. This not only improves the efficiency, safety and flexibility of the seamless stainless steel pipe welding defect sensing and detection equipment, but also optimizes the production process and reduces operating costs. By setting up a feeding chute, the inspected steel pipes can be fed into the chute. The internal rubber strips effectively slow down the falling speed of the steel pipes, reducing the impact force when the steel pipes come into contact with the bottom of the feeding chute, thereby reducing steel pipe damage and safety hazards. At the same time, the rubber strips form an elastic barrier between the steel pipes, preventing the two steel pipes from colliding with each other, significantly reducing the risk of damage caused by steel pipe collisions. In addition, by setting an adjustable support roller on one side of the inspection ring seat, the three-jaw chuck can clamp and push the other end of the steel pipe for support, so that the other end of the steel pipe remains stable when clamped during welding defect inspection, effectively improving the accuracy of welding inspection.

[0019] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] like Figures 1-8 The seamless stainless steel pipe welding defect sensing and detection device shown includes a frame 1, a three-jaw chuck 2 is provided on one side of the upper end of the frame 1, a detection ring seat 3 is fixedly connected to the other side of the upper end of the frame 1, a fixed frame 4 is fixedly connected to one side of the frame 1, a feeding component 5 is fixedly connected to the fixed frame 4, a pre-embedded seat 6 is fixedly connected to the bottom end of the fixed frame 4, a feeding trough 7 is fixedly connected through the middle of the frame 1, and a receiving component 8 is symmetrically arranged above the feeding trough 7.

[0021] Among them, the frame 1 is made of high-strength steel welded into shape, with a stable overall structure and strong vibration resistance, providing a stable installation and working foundation for each component. Its surface is treated with paint for rust prevention, making it suitable for the harsh working environment of industrial workshops. The three-jaw chuck 2 adopts a high-precision hydraulic three-jaw chuck, with uniform clamping force and high centering accuracy, which can be adapted to seamless stainless steel pipes of different diameters, ensuring the coaxiality of the steel pipe during testing.

[0022] like Figure 2 As shown, a hydraulic push rod 201 is fixedly connected to one side of the three-jaw chuck 2, and the hydraulic push rod 201 is fixedly connected to the frame 1 through it.

[0023] The hydraulic push rod 201 adopts a heavy-duty engineering hydraulic push rod, which has a large thrust and precise and controllable stroke. Its stroke can be flexibly adjusted according to the length of the steel pipe to be tested, and the maximum stroke is suitable for the testing needs of long pipes.

[0024] like Figure 3 As shown, the inner wall of the detection ring seat 3 is arranged in a ring structure with multiple ultrasonic sensors. An electric push rod 301 is fixedly connected to one side of the detection ring seat 3. An adjustment frame 302 is fixedly connected to the top of the electric push rod 301. A support roller 303 is rotatably connected to the adjustment frame 302.

[0025] The detection ring seat 3 is made of high-strength aluminum alloy, which is lightweight and rigid. The inner wall has a precision circular structure, and multiple ultrasonic sensors are evenly distributed in a ring, which can realize full coverage detection of circumferential welding defects of steel pipes. The electric actuator 301 adopts a servo electric actuator, with precise and controllable stroke and thrust. The height of the support roller 303 can be adjusted according to the diameter of the steel pipe to ensure that the support roller 303 is in close contact with the outer wall of the steel pipe.

[0026] like Figure 4 As shown, the fixing frame 4 is set with an inclined structure, and a guide plate 401 is fixedly connected to one side of the top of the fixing frame 4.

[0027] like Figure 5 As shown, the feeding assembly 5 includes a motor 501, which is fixedly connected to the bottom of the fixed frame 4. A lead screw 502 is fixedly connected to the output end of the motor 501. The lead screw 502 is rotatably connected to the fixed frame 4. A feeding plate 503 is threadedly connected to the outer wall of the lead screw 502. A transmission rack 504 is fixedly connected to one side of the feeding plate 503.

[0028] The motor 501 adopts a servo geared motor with precise and controllable speed and large torque. The feeding speed can be adjusted according to the weight of the steel pipe. The transmission rack 504 meshes with the transmission wheel 606 on the pre-embedded seat 6, which can convert the linear motion of the feeding plate 503 into the rotational motion of the transmission wheel 606, realizing the linkage switch of the protective plate 601. No additional power source is required, simplifying the equipment structure.

[0029] By setting up the feeding component 5, steel pipes on the ground can be automatically transported into the receiving component 8 and fixed by the three-jaw chuck 2. No manual handling is required, which reduces the workload of workers, shortens the production cycle, and improves the overall production efficiency. At the same time, when the feeding component 5 is retracted and reset, it can drive the protective plate 601 on the pre-embedded seat 6 to close automatically, preventing workers from falling. This not only improves safety, but also achieves a steady improvement in product quality by increasing efficiency, saving time, and reducing costs. like Figure 6As shown, a protective plate 601 is slidably fitted on one side of the inner wall of the embedded base 6. A groove 602 is provided at the bottom end of the protective plate 601. A rotating shaft 603 is rotatably connected through one side of the inner wall of the embedded base 6. An L-shaped rod 604 is fixedly connected to the top end of the rotating shaft 603. The outer wall of the top end of the L-shaped rod 604 is slidably fitted with the inner wall of the groove 602. A universal joint 605 is fixedly connected to the bottom end of the rotating shaft 603. One end of the universal joint 605 is rotatably connected to the inner wall of the embedded base 6. A transmission wheel 606 is fixedly connected to the other end of the universal joint 605. The transmission wheel 606 is movably meshed with the transmission rack 504 for transmission.

[0030] The embedded base 6 is embedded below the ground and fixedly connected to the ground foundation. The structure is stable and provides a stable installation base for the protective plate 601 and transmission components. The protective plate 601 is made of stainless steel plate with a smooth surface, which can effectively isolate the equipment operation area from the ground and prevent workers from falling.

[0031] like Figure 7 As shown, multiple rubber strips 701 are fixedly connected to the upper side of the inner wall of the feeding trough 7, and a baffle 702 is provided at the bottom opening of the feeding trough 7.

[0032] Rubber strip 701 is made of oil-resistant, wear-resistant, and highly elastic natural rubber; baffle 702 is made of rubber on one side to avoid scratching the surface of the steel pipe.

[0033] like Figure 8 As shown, the receiving assembly 8 includes a movable frame 801, a hydraulic cylinder 802 is fixedly connected to the bottom of the movable frame 801, the hydraulic cylinder 802 is fixedly connected to the frame 1 through the hydraulic cylinder 802, and a receiving plate 803 is rotatably connected to the top of the movable frame 801.

[0034] A transmission rod 804 is rotatably connected to the bottom of the movable frame 801. Two push rods 805 are fixedly connected to the transmission rod 804 in a symmetrical structure. The other end of the push rod 805 is slidably in contact with one side of the receiving plate 803. A worm gear 806 is fixedly connected to one end of the transmission rod 804. A worm 807 is meshed with one side of the worm gear 806. The worm 807 is rotatably connected to the movable frame 801. An adjusting wheel 808 is fixedly connected to one end of the worm 807. A fixed rack 809 is meshed with one side of the adjusting wheel 808. The fixed rack 809 is fixedly connected to the frame 1.

[0035] Working principle: Before the equipment starts, the feeding plate 503 of the feeding assembly 5 is at its lowest position on the ground. At this time, the transmission rack 504 drives the transmission wheel 606 to rotate. Through the transmission of the universal joint 605, the rotating shaft 603 and the L-shaped rod 604, the protective plate 601 on the embedded seat 6 is in a closed state, isolating the equipment operation area. The hydraulic cylinder 802 of the receiving assembly 8 drives the moving frame 801 to the feeding high position. The three-jaw chuck 2 is in the initial retracted state, and the hydraulic push rod 201 is in the retracted state. The electric push rod 301 of the detection ring seat 3 drives the support roller 303 to the low position, and the baffle 702 of the unloading chute 7 closes naturally. The detection sensor is in standby state.

[0036] The seamless stainless steel pipe to be tested is placed at the bottom of the fixed frame 4. The motor 501 of the feeding assembly 5 is started. The motor 501 drives the lead screw 502 to rotate, causing the feeding plate 503 to move upward in a straight line along the fixed frame 4. Then the feeding plate 503 moves out, lifts the steel pipe and slides upward. After being guided by the guide plate 401, it falls precisely into the V-shaped centering groove formed by the receiving plates 803 of the two receiving assemblies 8, realizing automatic centering. During the upward movement of the feeding plate 503, the transmission rack 504 on one side meshes with the transmission wheel 606, driving the transmission wheel 606 to rotate. Through the universal joint 605 and the rotating shaft 603, the L-shaped rod 604 is driven to rotate. The top of the L-shaped rod 604 slides along the slide groove 602 of the protective plate 601, driving the protective plate 601 to move upward and open, without affecting the feeding action.

[0037] After the steel pipe falls into the receiving plate 803, the V-shaped centering groove realizes the automatic centering of the steel pipe, ensuring that the axis of the steel pipe coincides with the axis of the three-jaw chuck 2; the hydraulic cylinder 802 of the receiving component 8 drives the moving frame 801 to move upward according to the diameter of the steel pipe, adjusting the steel pipe to the clamping height that matches the three-jaw chuck 2; then the hydraulic push rod 201 extends, driving the three-jaw chuck 2 to move towards the steel pipe, one end of the steel pipe enters between the jaws of the three-jaw chuck 2, the three-jaw chuck 2 starts, the jaws retract and firmly clamp the end of the steel pipe, realizing the precise fixation of the steel pipe.

[0038] After the steel pipe is clamped, the electric push rod 301 on one side of the detection ring seat 3 is activated, driving the adjusting frame 302 and the support roller 303 to move upward, so that the support roller 303 is aligned with the bottom of the steel pipe. Then, multiple ultrasonic sensors of the detection ring seat 3 are activated and enter the detection state. The hydraulic push rod 201 continues to extend at a constant speed, driving the three-jaw chuck 2 and the steel pipe to move horizontally in a straight line towards the detection ring seat 3. The steel pipe passes through the detection ring seat 3 at a constant speed. The ultrasonic sensors perform 360° full coverage detection of the circumference of the steel pipe, identify welding defects in real time, and transmit the detection signal to the control system. At the same time, the support roller 303 supports one end of the steel pipe.

[0039] When the steel pipe has completely passed through the inspection ring seat 3 and the welding defect inspection is completed, the control system will feed back and record the inspection results; the hydraulic push rod 201 retracts, driving the three-jaw chuck 2 and the inspected steel pipe to move to the initial position, and at the same time the three-jaw chuck 2 releases the steel pipe; the hydraulic cylinder 802 of the receiving assembly 8 starts, driving the moving frame 801 and the steel pipe to move downward. During the downward movement of the moving frame 801, the adjusting wheel 808 on one side rolls and rotates along the fixed rack 809 on the frame 1, driving the worm 807 to rotate. The worm 807 meshes with the worm wheel 806 to drive the transmission rod 804 to rotate. The push rod 805 on the transmission rod 804 is reset, so that the receiving plate 803 rotates under its own weight and the weight of the steel pipe. The two receiving plates 803 separate, so that the steel pipe can fall automatically.

[0040] After the steel pipe slides into the feeding trough 7, it is buffered multiple times by the rubber strip 701 on the inner wall, which greatly reduces the falling speed and avoids collision with the feeding trough 7 and damage. The steel pipe is limited by the baffle 702 and stops moving, and then the steel pipe can be taken out. After the feeding is completed, the motor 501 of the feeding assembly 5 reverses, driving the lead screw 502 to rotate in the opposite direction, so that the feeding plate 503 is retracted downwards to the lowest position on the ground. The transmission rack 504 drives the transmission wheel 606 to rotate in the opposite direction, and through the transmission components, it drives the protective plate 601 to move downwards and automatically close, restoring the equipment to the protective state. The hydraulic cylinder 802 of the receiving assembly 8 extends, driving the moving frame 801 to move upwards and reset. The adjusting wheel 808 rolls in the opposite direction along the fixed rack 809, driving the receiving plate 803 to rotate and reset. The electric push rod 301 of the detection ring seat 3 drives the support roller 303 to move downwards and reset. The equipment returns to the initial state and waits for the next steel pipe to be inspected. This cycle is repeated to realize the continuous automated detection of welding defects in seamless stainless steel pipes.
