Abstract
Description
Technical Field
[0001] This utility model relates to the field of flaw detection device technology, and in particular to a high-frequency welded pipe flaw detection device. Background Technology
[0002] Flaw detection devices are used to inspect high-frequency welded pipes for defects at the weld joints. These devices are typically ultrasonic flaw detectors. When inspecting high-frequency welded pipes, the ultrasonic flaw detector is activated, and the probe is brought into contact with the pipe. The ultrasonic generator inside the flaw detector produces ultrasonic waves. These ultrasonic waves penetrate deep into the metal material and, when they travel from one section to another, are reflected at the interface edge. This characteristic is used to inspect for defects in the parts. When the ultrasonic beam encounters a defect or the bottom surface of the part, reflected waves are generated, forming pulse waveforms on the screen of the ultrasonic flaw detector. The location and size of the defect are determined based on these pulse waveforms, thus enabling flaw detection of the high-frequency welded pipe.
[0003] The inventors discovered in their daily work that when using the flaw detection device, the probe needs to contact the high-frequency welded pipe. When detecting flaws in the high-frequency welded pipe, the worker needs to manually rotate the high-frequency welded pipe one full turn so that the probe can detect flaws in the high-frequency welded pipe. Since the worker needs to manually rotate the high-frequency welded pipe continuously, it may increase the worker's labor intensity. Utility Model Content
[0004] The purpose of this invention is to solve the problem that in actual use, when the probe needs to contact the high-frequency welded pipe, the worker needs to manually rotate the high-frequency welded pipe one full turn so that the probe can inspect the high-frequency welded pipe. Since the worker needs to manually rotate the high-frequency welded pipe continuously, it may increase the labor intensity of the worker. Therefore, a high-frequency welded pipe inspection device is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-frequency welded pipe flaw detection device, comprising a base, a U-shaped frame and an ultrasonic flaw detector fixedly connected to the upper end of the base, a hydraulic rod fixedly connected to the lower end of the U-shaped frame, an installation component and a probe provided at the lower end of the hydraulic rod, the probe and the ultrasonic flaw detector being connected by a wire, an auxiliary component provided at the upper end of the base, the auxiliary component including an installation ring fixedly connected to the upper end of the base, a toothed ring provided on the front side of the installation ring, a circular ring fixedly connected to the front side of the toothed ring, and clamping blocks provided on both sides of the inner wall of the circular ring.
[0006] The effect achieved by the above-mentioned components is as follows: by setting auxiliary components, when inspecting high-frequency welded pipes, the high-frequency welded pipe is dragged and inserted between two clamping blocks inside the circular ring on the mounting ring. Through the pushing mechanism, the clamping blocks on both sides are pressed against the high-frequency welded pipe for fixation. Then, the hydraulic rod under the U-shaped frame on the base is activated, so that the probe contacts the high-frequency welded pipe. Then, through the driving mechanism, the toothed ring is rotated, so that the high-frequency welded pipe rotates slowly, thereby allowing the probe to perform inspection. This avoids the need for manual rotation of the high-frequency welded pipe for inspection as much as possible and reduces the intensity of manual labor.
[0007] Preferably, a guide rod is fixedly connected to the arc surface of the clamping block, a circular ring is slidably inserted into the guide rod, and a screw is rotatably connected to the arc surface of the clamping block, with the screw and the circular ring being threadedly connected.
[0008] The effect achieved by the above components is that turning the screw, under the limit of the guide rod, pushes the clamping block.
[0009] Preferably, a gear is provided on the front side of the mounting ring, and the gear meshes with the gear ring.
[0010] The effect achieved by the above components is that the gear rotates, causing the gear ring to rotate.
[0011] Preferably, a motor is mounted on the back of the mounting ring, and the output end of the motor is fixed to the gear.
[0012] The effect achieved by the above components is to start the motor, which, in conjunction with the encoder, causes the gears to rotate.
[0013] Preferably, a positioning ring is fixedly connected to the front side of the mounting ring, and a bearing is provided between the positioning ring and the toothed ring. The outer ring of the bearing is fixed to the toothed ring, and the inner ring of the bearing is fixed to the positioning ring.
[0014] The effect achieved by the above components is to improve the rotational stability of the gear ring by setting up a positioning ring and bearings.
[0015] Preferably, the mounting assembly includes a connector fixedly connected to the output end of the hydraulic rod, and an insert rod is slidably inserted into the inner wall of the connector, the insert rod being inserted into the probe.
[0016] The effect achieved by the above components is as follows: when a probe needs to be installed, the probe is snapped into the connector, and the probe is inserted through the plug rod to install and fix the probe.
[0017] Preferably, a spring is fixedly connected to the left end of the insertion rod, and the other end of the spring is fixed to the connector.
[0018] The effect achieved by the above components is to reset the insertion rod by setting a spring.
[0019] Preferably, a pull rope is fixedly connected to the left end of the insertion rod, and the pull rope passes through the connector.
[0020] The effect achieved by the above components is that pulling the rope causes the plug rod to be pulled.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] In this invention, by setting an auxiliary component, when inspecting high-frequency welded pipes, the high-frequency welded pipe is dragged and inserted between two clamping blocks inside the circular ring on the mounting ring. A pushing mechanism then presses the clamping blocks on both sides against the high-frequency welded pipe for fixation. Next, the hydraulic rod under the U-shaped frame on the base is activated, causing the probe to contact the high-frequency welded pipe. Then, a driving mechanism rotates the gear ring, causing the high-frequency welded pipe to rotate slowly, allowing the probe to perform the inspection. This minimizes the need for manual rotation of the high-frequency welded pipe during inspection, reducing labor intensity. It solves the problem that when inspecting high-frequency welded pipes, workers need to manually rotate the pipe one full turn so that the probe can inspect it, which increases the labor intensity for workers due to the need for continuous manual rotation.

[0029] The following section will explain the specific settings and functions of auxiliary component 2 and installation component 3.
[0030] Reference Figure 2 and Figure 3 As shown in this embodiment: the auxiliary component 2 includes a mounting ring 21 fixedly connected to the upper end of the base 1. A toothed ring 22 is provided on the front of the mounting ring 21, and a circular ring 23 is fixedly connected to the front of the toothed ring 22. Clamping blocks 24 are provided on both sides of the inner wall of the circular ring 23. By setting the auxiliary component 2, when inspecting the high-frequency welded pipe, the high-frequency welded pipe is dragged so that it is clamped between the two clamping blocks 24 in the circular ring 23 on the mounting ring 21. By pushing the mechanism, the clamping blocks 24 on both sides are pressed against the high-frequency welded pipe for fixation. Then, the hydraulic rod 5 under the U-shaped frame 4 on the base 1 is activated, so that the probe 6 contacts the high-frequency welded pipe. Then, by driving the mechanism, the toothed ring 22 is rotated, so that the high-frequency welded pipe rotates slowly, thereby allowing the probe 6 to perform inspection. This avoids the need for manual rotation of the high-frequency welded pipe for inspection as much as possible and reduces the intensity of manual labor. The arc surface of the clamping block 24 is fixed. A guide rod 28 is fixedly connected, and a circular ring 23 is slidably inserted into the guide rod 28. A screw 27 is rotatably connected to the arc surface of the clamping block 24. The screw 27 and the circular ring 23 are threadedly connected. Tightening the screw 27, under the limit of the guide rod 28, pushes the clamping block 24. A gear 25 is provided on the front side of the mounting ring 21. The gear 25 meshes with the gear ring 22. The rotation of the gear 25 causes the gear ring 22 to rotate. A motor 26 is installed on the back side of the mounting ring 21. The output end of the motor 26 is fixed to the gear 25. Starting the motor 26, in conjunction with the encoder, causes the gear 25 to rotate. A positioning ring 29 is fixedly connected to the front side of the mounting ring 21. A bearing 210 is provided between the positioning ring 29 and the gear ring 22. The outer ring of the bearing 210 is fixed to the gear ring 22, and the inner ring of the bearing 210 is fixed to the positioning ring 29. By setting the positioning ring 29 and the bearing 210, the rotational stability of the gear ring 22 is improved.
[0031] Reference Figure 4As shown in this embodiment: the installation component 3 includes a connector 31 fixedly connected to the output end of the hydraulic rod 5. A rod 32 is slidably inserted into the inner wall of the connector 31. The rod 32 is inserted into the probe 6. When the probe 6 needs to be installed, the probe 6 is snapped into the connector 31 and the rod 32 is inserted into the probe 6 to install and fix the probe 6. A spring 34 is fixedly connected to the left end of the rod 32. The other end of the spring 34 is fixed to the connector 31. By setting the spring 34, the rod 32 is reset. A pull rope 33 is fixedly connected to the left end of the rod 32. The pull rope 33 passes through the connector 31. Pulling the pull rope 33 causes the rod 32 to be pulled.
[0032] Working principle:
[0033] When inspecting high-frequency welded pipes, the ultrasonic flaw detector 7 (model DECCADK-2300) is activated. The probe 6 is brought into contact with the high-frequency welded pipe. The ultrasonic generator inside the ultrasonic flaw detector 7 generates ultrasonic waves. These ultrasonic waves penetrate deep into the metal material and reflect off the interface edges when they travel from one section to another. This is a method for inspecting part defects. When the ultrasonic beam encounters a defect or the bottom surface of the part, reflected waves are generated, forming pulse waveforms on the screen of the ultrasonic flaw detector 7. The location and size of the defect are determined based on these pulse waveforms, thus inspecting the high-frequency welded pipe. For better inspection, the high-frequency welded pipe is dragged until it is engaged between the two clamping blocks 24 within the circular ring 23 on the mounting ring 21. The screw 27 is then turned, and the guide rod 28 is engaged. The position is lowered, causing the clamping block 24 to be pushed, so that the clamping blocks 24 on both sides are pressed against the high-frequency welded pipe for fixation. Then, the hydraulic rod 5 under the U-shaped frame 4 on the base 1 is activated, so that the probe 6 contacts the high-frequency welded pipe. Then, the motor 26 is started, and with the encoder, the gear 25 rotates, so that the gear ring 22 rotates, and the high-frequency welded pipe rotates slowly, so that the probe 6 can perform detection. This can avoid manual rotation of the high-frequency welded pipe for detection as much as possible and reduce the intensity of manual labor. By setting the positioning ring 29 and bearing 210, the rotational stability of the gear ring 22 is improved. When the probe 6 needs to be installed, the probe 6 is inserted into the connector 31, and the probe 6 is installed and fixed by inserting the rod 32. The spring 34 is set to reset the rod 32, and the pull rope 33 is pulled, so that the rod 32 is pulled.
