Description

Technical Field

[0001] The utility model relates to the technical field of pipeline flaw detection, and particularly relates to a positioning device for ultrasonic flaw detection. Background Technique

[0002] Ultrasonic flaw detection technology is a non-destructive testing method widely used in the detection of material defects in structures such as pipelines, bridges, and buildings. Its principle is to use ultrasonic signals to penetrate the interior of the material. According to information such as the strength and time characteristics of the reflected signals, it is possible to determine whether there are defects inside the material and locate and classify them. However, traditional ultrasonic flaw detection technology is usually fixed on the surface of the detection object, and manual adjustment of the detection position is required. The operation is complex and the efficiency is low, making it difficult to meet the comprehensive flaw detection requirements for complex-shaped structures such as pipelines.

[0003] Existing positioning devices have limitations in use. Traditional non-destructive testing equipment, such as RT ray detection, UT ultrasonic detection, MT magnetic particle detection, and PT penetrant detection equipment, usually has a fixed structure and can only be used for detection at specific positions. For pipelines with a large diameter or situations where continuous detection along the pipeline surface is required, these devices are difficult to adapt to, the operation is inconvenient, and it is difficult to achieve all-round and efficient detection. In addition, there is a large sliding resistance between the probe of some devices and the pipeline surface, making it difficult to achieve smooth sliding.

[0004] Therefore, a positioning device for ultrasonic flaw detection is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a positioning device for ultrasonic flaw detection to solve the problems raised in the above background technique.

[0006] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0007] A positioning device for ultrasonic flaw detection includes a U-shaped frame and a handheld ultrasonic flaw detection device. Transverse adjustment mechanisms are arranged on both side walls of the U-shaped frame, and a support frame assembly is arranged at the end of the transverse adjustment mechanism. Rubber wheels are rotatably installed on the surface of the support frame assembly. A vertical adjustment mechanism is arranged on the top surface of the U-shaped frame, and the detection end of the handheld ultrasonic flaw detection device is inserted into the movable end of the vertical adjustment mechanism.

[0008] Furthermore, the transverse adjustment mechanism includes a first threaded rod. The first threaded rods are respectively threadedly inserted into both side walls of the U-shaped frame. A first knob is fixedly installed at the end of the first threaded rod. Guide rods are movably inserted into both side walls of the U-shaped frame.

[0009] Furthermore, the support frame assembly includes a side plate, the end of the first threaded rod is rotatably mounted with the first threaded rod, and the end face of the first threaded rod and the end of the guide rod are fixedly mounted, the other end face of the side plate is fixedly mounted with an L-shaped frame, a protrusion is fixedly mounted on the surface of the L-shaped frame, and a rubber wheel is rotatably mounted inside the protrusion.

[0010] Furthermore, the vertical adjustment mechanism includes a second threaded rod, the top surface of the U-shaped frame is threadedly plugged with the second threaded rod, and the top of the second threaded rod is fixedly mounted with a second knob, the bottom end of the second threaded rod is rotatably mounted with a movable plate, the top surface of the movable plate is fixedly mounted with a guide rod, and the guide rod and the U-shaped frame are movably plugged, and the inner wall of the movable plate is fixedly mounted with a rubber ring.

[0011] Furthermore, the handheld ultrasonic flaw detection equipment comprises a probe, the inside of the rubber ring is fixedly plugged with the probe, the end of the probe is connected with a wire, and the end of the wire is fixedly mounted with a handheld host.

[0012] Furthermore, the surface of the rubber wheel is provided with an anti-skid pattern, and when the pipeline is inspected, the rubber wheel is arranged to fit the outer surface of the pipeline.

[0013] The beneficial effects of the utility model are as follows:

[0014] The positions of the two groups of support frame assemblies are adjusted respectively by two groups of lateral adjustment mechanisms, so that the rubber wheel rotatably mounted on the surface of the support frame assembly fits with the outer surface of the pipe. The position of the rubber wheel can be adjusted and the rubber wheel is in a V-shaped structure, so that it can adapt to the use of pipes with different diameters. The distance between the detection end of the handheld ultrasonic flaw detection equipment and the pipe surface is adjusted by the vertical adjustment mechanism. The pipe is then inspected by the handheld ultrasonic flaw detection equipment. The rubber wheel is rotatably mounted on the support frame assembly, so that the positioning device can move along the surface of the pipe during the inspection, so that the position of the handheld ultrasonic flaw detection equipment can be moved. By equipping the U-shaped frame and the matching lateral and vertical adjustment mechanisms, this device can adapt to more variable inspection environments, especially for pipes with larger diameters. Whether it is the precise positioning of the inspection starting point or the continuous inspection along the pipe surface, it can achieve all-round coverage, greatly improving the comprehensiveness of the inspection. The design of the rubber wheel cleverly reduces the sliding resistance between the probe and the pipe surface, making the inspection process smoother and smoother, while ensuring the stability of the equipment during large-scale movement and optimizing the operating experience.

[0024] As Figures 1 to 4 shown, a positioning device for ultrasonic flaw detection includes a U-shaped frame 1 and a handheld ultrasonic flaw detection device 6. Transverse adjustment mechanisms 2 are provided on both side walls of the U-shaped frame 1, and support frame assemblies 3 are provided at the ends of the transverse adjustment mechanisms 2. Rubber wheels 4 are rotatably installed on the surfaces of the support frame assemblies 3. A vertical adjustment mechanism 5 is provided on the top surface of the U-shaped frame 1, and the detection end of the handheld ultrasonic flaw detection device 6 is inserted into the movable end of the vertical adjustment mechanism 5. More specifically, through the two sets of transverse adjustment mechanisms 2, the positions of the two sets of support frame assemblies 3 are respectively adjusted, so that the rubber wheels 4 rotatably installed on the surfaces of the support frame assemblies 3 are in contact with the outer surface of the pipeline. Since the position of the rubber wheel 4 can be adjusted and the rubber wheel 4 has a V-shaped structure, it can be adapted to pipelines of different diameters. The distance between the detection end of the handheld ultrasonic flaw detection device 6 and the pipeline surface is adjusted through the vertical adjustment mechanism 5, and the pipeline is subjected to flaw detection through the handheld ultrasonic flaw detection device 6. Since the rubber wheel 4 is rotatably installed on the support frame assembly 3, the positioning device can move along the surface of the pipeline during detection, so that the position of the handheld ultrasonic flaw detection device 6 can be moved.

[0025] The transverse adjustment mechanism 2 includes a first threaded rod 201. The first threaded rods 201 are respectively inserted into the two side walls of the U-shaped frame 1 in a threaded manner. A first knob 202 is fixedly installed at the end of the first threaded rod 201. Guide rods 203 are movably inserted into the two side walls of the U-shaped frame 1. More specifically, the first threaded rod 201 is rotated by driving the first knob 202. Since the first threaded rod 201 is inserted into the U-shaped frame 1 in a threaded manner, the transverse positions of the support frame assembly 3 and the rubber wheel 4 can be adjusted.

[0026] The support frame assembly 3 includes side plates 301. The first threaded rod 201 is rotatably installed at the end of the first threaded rod 201, and the end surface of the first threaded rod 201 and the end of the guide rod 203 are fixedly installed. The other end surface of the side plate 301 is fixedly installed with an L-shaped frame 302. A convex block 303 is fixedly installed on the surface of the L-shaped frame 302, and a rubber wheel 4 is rotatably installed inside the convex block 303. More specifically, the rubber wheel 4 can be supported through the convex block 303 on the surface of the L-shaped frame 302. Since the L-shaped frame 302 enables the rubber wheel 4 to be installed in a V-shaped manner, after the position of the rubber wheel 4 is adjusted by the transverse adjustment mechanism 2, it can be adapted to pipelines of different diameters.

[0027] The vertical adjustment mechanism 5 includes a second threaded rod 501. The top surface of the U-shaped frame 1 is threadedly inserted with the second threaded rod 501, and a second knob 502 is fixedly installed at the top end of the second threaded rod 501. The bottom end of the second threaded rod 501 is rotatably installed with a movable plate 503. A guide rod 504 is fixedly installed on the top surface of the movable plate 503, and the guide rod 504 and the U-shaped frame 1 are movably inserted. A rubber ring 505 is fixedly installed on the inner wall of the movable plate 503. More specifically, by driving the second threaded rod 501 to rotate through the second knob 502, and through the threaded insertion of the second threaded rod 501 and the U-shaped frame 1, the movable plate 503 is vertically moved, so that the distance between the detection end of the handheld ultrasonic flaw detector 6 and the pipe surface can be adjusted.

[0028] The handheld ultrasonic flaw detector 6 includes a probe 601. The probe 601 is fixedly inserted into the rubber ring 505, and a wire 602 is connected to the end of the probe 601. A handheld host 603 is fixedly installed at the end of the wire 602. More specifically, the handheld host 603 controls the probe 601 to emit ultrasonic waves through the wire 602 to detect the scars on the pipe.

[0029] Anti-slip patterns are provided on the surface of the rubber wheel 4. When detecting the pipe, the rubber wheel 4 is in close contact with the outer surface of the pipe. More specifically, by providing anti-slip patterns on the surface of the rubber wheel 4, the friction force in contact with the pipe is increased, so that the device can move along the surface of the pipe.

[0030] In summary: By two groups of horizontal adjustment mechanisms 2, the positions of the two groups of support frame assemblies 3 are respectively adjusted, so that the rubber wheels 4 rotatably installed on the surface of the support frame assemblies 3 are in close contact with the outer surface of the pipe. By being able to adjust the position of the rubber wheels 4 and the rubber wheels 4 having a V-shaped structure, it is possible to adapt to pipes of different diameters. The distance between the detection end of the handheld ultrasonic flaw detector 6 and the pipe surface is adjusted by the vertical adjustment mechanism 5. By the handheld ultrasonic flaw detector 6, the pipe is flaw detected. By the rubber wheels 4 being rotatably installed with the support frame assemblies 3, the positioning device can move along the surface of the pipe during detection, so that the position of the handheld ultrasonic flaw detector 6 can be moved.
