technical field

The utility model relates to an ultrasonic guided wave probe fixing device, in particular to a novel adjustable ultrasonic guided wave probe fixing device for high-pressure tank detection, which belongs to the field of high-pressure tank equipment non-destructive testing.

Background technique

In recent years, accidents caused by cracks and corrosion of some high-pressure tanks have occurred frequently, which not only cause harm to people's lives and health, but also leave people with a lot of psychological damage, forming fear of some high-pressure tanks Therefore, how to effectively and quickly detect and check some high-pressure tanks with potential safety hazards has become a problem that people need to pay attention to. At present, ultrasonic guided wave technology has been widely used in the detection of cracks and corrosion in equipment such as long transportation pipelines, plates, and high-pressure tanks. When using ultrasonic guided wave technology for detection, ultrasonic guided wave probes generally require special fixtures and objects to be tested. They are fixed together to achieve accurate detection, but different fixing devices are required for pipes of different diameters or high-pressure tanks, which will not only increase the detection cost, but also consume time and effort. Therefore, how to install the ultrasonic guided wave probe on high-pressure tanks with different diameters has become a problem to be solved.

Utility model content

According to the above problems, the utility model proposes a novel adjustable ultrasonic guided wave probe fixing device for high-pressure tank detection.

detailed description

As shown in Figures 1 to 4, the utility model discloses a new type of adjustable ultrasonic guided wave probe fixing device for high-pressure tank detection. Its structure mainly includes: a right-angle connecting rod 1, a connecting pin 2, a first telescopic rod 3, Fixed pin 4, connecting rod 5, tightening nut 6, bolt with hole 7, probe cover 8, V-shaped block 9, second telescopic rod 10, object under test 11, plug 12, long bolt 13, guide block with threaded hole 14 etc. Wherein the right angle connecting rod and the first telescopic rod, the connecting rod and the V-shaped block are fixedly connected by connecting pins; the first telescopic rod and the connecting rod, the right angle connecting rod and the second connecting rod are connected by fixed pins; tighten the nut It is threadedly connected with bolts with holes, guide blocks with threaded holes and long bolts.

The working process of this embodiment is described in detail as follows.

As shown in Figure 1, it is suitable for high-pressure tanks with large diameters, such as small boilers. First, pull out the fixing pin 4 on the entire fixing device, pull out the first telescopic rod 3 and the second telescopic rod 10 respectively to the longest state, and then put the fixing device on a suitable position of the outer diameter of the measured object 11 . Then push the first telescopic rod 3 and the second telescopic rod 10 inwards to the outside of the measured object 11 close to the inside of the V-shaped block 9, at this time pass the first telescopic rod 3 and the second telescopic rod with the fixing pin 4 The through hole is connected with the right-angled connecting rod 1 and the connecting rod 5. At this time, the plug 12 is pressed against the outer wall of the measured object 11 by rotating the long bolt 13. Finally, the probe cover 8 is brought into contact with the measured object 11 by turning the tightening nut 6 , so far the entire fixing process of the ultrasonic guided wave probe is completed. In order to avoid touching the ultrasonic guided wave probe during disassembly, the nut 6 should be rotated and tightened first to keep the probe cover away from the measured object 11, and then the long bolt 13 can be rotated to separate the fixing device from the measured object 11. Finally, for easy access and space saving The connecting pin 2 and the fixing pin 4 can all be dismounted, and the whole device can be disassembled into a single component for easy portability.

As shown in Figure 3, it is suitable for high-pressure tanks with small diameters, such as gas tanks, oxygen tanks, etc. Its specific implementation process is roughly the same as the process described in Figure 1 above.
