Description

Technical Field

[0001] The utility model relates to pipeline flaw detection technology, in particular to a pipeline flaw detection and positioning device. Background Art

[0002] An ultrasonic flaw detector is a portable industrial non-destructive flaw detection instrument. It can quickly, conveniently, non-destructively and accurately detect, locate, evaluate and diagnose various internal defects of workpieces. During the process of non-destructively detecting a pipeline with an ultrasonic detector, an operator needs to hold the ultrasonic detector by hand, and hold the detection head of the ultrasonic detector with the other hand and stick it to the outer wall of the pipeline to detect along the pipeline. Then, according to the results of ultrasonic detection, the pipeline can be inspected for damage or defects without damage.

[0003] Therefore, during pipeline detection, the detector needs to hold the ultrasonic probe and move it along the outer wall of the pipeline. The existing ultrasonic detection probe is small in size. The detector needs to hold the small-sized ultrasonic detection probe for a long time and keep the bottom of the ultrasonic probe in contact with the outer wall of the pipeline while moving, which causes the hand to become stiff after holding the ultrasonic detection probe for a long time to keep the bottom of the probe in contact with the outer wall of the pipeline. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a pipeline flaw detection and positioning device, which is used to solve the problems that the hand becomes stiff after holding the ultrasonic detection probe for a long time to keep the bottom of the probe in contact with the outer wall of the pipeline, and it is not convenient to hold the ultrasonic detection probe.

[0005] To solve the above problems, the utility model provides a pipeline flaw detection and positioning device, which includes a support installed on the ultrasonic detection probe. Cross-shaped circular grooves are opened on both the upper and lower sides of the support. A rotating column is rotatably connected in the circular groove. Both ends of the rotating column extend out of the support and are respectively fixed with a support rod. A plurality of slots arranged in an annular array are opened in the middle of the rotating column. The middle part of the rotating column can partially extend out of the support. Two L-shaped grooves are opened on one side of the support. An L-shaped plate that can move up and down is arranged in the L-shaped groove. One end of the L-shaped plate is fixed with an L-shaped positioning plate, and one end of the positioning plate can be inserted into the corresponding slot on the rotating column.

[0006] The pipeline flaw detection and positioning device provided by the utility model further has the following technical features:

[0007] Further, two grips are fixed on one side of the support.

[0008] Further, one side of the L-shaped plate is connected to the support through a tension spring, and the end of the L-shaped plate away from the positioning plate extends out of the L-shaped groove.

[0009] Further, a torsion spring is sleeved on the rotating column. One end of the torsion spring is fixed to the support rod, and the other end of the torsion spring is fixed to the support.

[0010] Furthermore, a limiting groove is formed at the free end of the support rod. A ejector rod is slidably connected in the limiting groove. One end of the ejector rod extends out of the limiting groove, and the other end of the ejector rod is connected to the support rod through a first spring.

[0011] Furthermore, a rotatable roller is provided at the end of the ejector rod extending out of the limiting groove.

[0012] The utility model has the following beneficial effects: By bringing the bottom of the ultrasonic detection probe into contact with the outer wall of the pipeline, and by adjusting the positions of the four support rods, the support rods can support the position of the ultrasonic detection probe. When moving the ultrasonic detection probe, it is only necessary to press the support to move it, without deliberately keeping the state that the bottom of the ultrasonic detection probe is in contact with the outer wall of the pipeline when moving the ultrasonic detection probe, thereby relieving the pressure on the hand, facilitating the movement of the ultrasonic detection probe, and avoiding hand stiffness.

The middle part of the rotating column 3 is provided with a plurality of slots 5 arranged in a circular array, and the middle part of the rotating column 3 can partially extend out of the support 2. Two L-shaped grooves are provided on one side of the support 2, and an L-shaped plate 6 that can move up and down is provided in the L-shaped groove, and an L-shaped positioning The positioning plate 7, one end of which can be inserted into the slot 5 on the corresponding rotating column 3, is used to make the bottom of the ultrasonic detection probe 1 contact the outer wall of the pipe, and the positions of the four support rods 4 are adjusted so that the support rods 4 can play a role in supporting the position of the ultrasonic detection probe 1, so that when moving the ultrasonic detection probe 1, it is only necessary to press the support 2 to move it, and there is no need to deliberately keep the bottom of the ultrasonic detection probe 1 in contact with the outer wall of the pipe when moving the ultrasonic detection probe 1, thereby relieving the pressure on the hand, making it easier to move the ultrasonic detection probe 1 and avoiding hand stiffness.

[0020] In one embodiment of the present application, preferably, two handles 8 are fixed to one side of the support 2. The provision of the two handles 8 can facilitate an operator to hold the support 2 and the ultrasonic detection probe 1.

[0021] In one embodiment of the present application, preferably, one side of the L-shaped plate 6 is connected to the support 2 via a tension spring 9, and one end of the L-shaped plate 6 away from the positioning plate 7 extends out of the L-shaped groove, so that under normal conditions the positioning plate 7 can be inserted into the slot 5 under the action of the tension spring 9, thereby fixing the position of the support rod 4, and making it easier to adjust the angle of the support rod 4, which can be applicable to pipes of various different diameters.

[0022] In one embodiment of the present application, preferably, a torsion spring 10 is sleeved on the rotating column 3, one end of the torsion spring 10 is fixedly connected to the support rod 4, and the other end of the torsion spring 10 is fixedly connected to the support 2, so that in the initial state, the four support rods 4 are parallel to each other. When in use, the bottom of the ultrasonic detection probe 1 is pressed against the outer wall of the pipe, so that the four support rods 4 are stretched open, the torsion spring 10 is in a force storage state, and then the positioning plate 7 is inserted into the slot 5 under the action of the tension spring 9.
