Embodiment 1

[0021] see Figure 1~3 , in an embodiment of the present invention, a pipeline circumferential ultrasonic flaw detection device includes a first ring body 1, a second ring body 2, a detection mechanism arranged on the first ring body 1 and the second ring body 2, and the detection mechanism is directed to Matched semicircular inner rack 3 and base 18;

[0022] Wherein, the inner walls of the first ring body 1 and the second ring body 2 are fixed with a semicircular inner rack 3, the upper ends of the first ring body 1 and the second ring body 2 are hinged, and the first ring body 1 and the second ring body The lower ends of the two rings 2 are connected by locks. After the locks are opened, the hinged first ring 1 and the second ring 2 can be opened, so that they can be sleeved on the outer wall of the pipeline. What needs to be explained Yes, a complete circle is formed between the first ring body 1 and the second ring body 2 after the lock is locked.

[0023] Specifically,...

Embodiment 2

[0028] In order to further explain the above-mentioned pipeline circumferential ultrasonic flaw detection device, in another embodiment of the present invention, a pipeline circumferential ultrasonic flaw detection device, the lower part of the first ring body 1 is fixedly connected to the support frame 16, and the support frame 16 is fixed on the base 18 Above, the first ring body 1 is fixed by the support frame 16 and the fixing seat 18 to maintain overall stability.

Abstract

The invention discloses a pipeline circumferential ultrasonic flaw detection device. A pipeline is wrapped by two hinged ring bodies, and a rotating gear cooperates with gear rings fixed on inner walls of the ring bodies to drive the circular motion of an entire detection mechanism, and the problem that the existing pipeline flaw detection requires manual winding is effectively solved. Semicircular internal racks are fixed to the inner walls of the first ring body and the second ring body, an upper end of the first ring body is hinged with the upper end of the second ring body, a the lower endof the first ring body is cooperatively connected with the lower end of the second ring body through a lock catch; and the detection mechanism comprises a mounting seat arranged on outer walls of thefirst ring body and the second ring body, a motor fixedly connected to the mounting seat, a gear connected with an output end of the motor through a transmission member, a fixing frame fixedly connected with the mounting seat and used for rotationally mounting the gear, and a fitting component arranged at an end part of the fixing frame, and the gear is engaged with the semicircular internal racks.

Description

technical field [0001] The invention relates to the detection field, in particular to a pipeline circumferential ultrasonic flaw detection device. Background technique [0002] Non-destructive testing is an indispensable and effective tool for industrial development, which reflects the industrial development level of a country to a certain extent. The importance of non-destructive testing has been recognized, mainly including radiographic testing (RT), ultrasonic testing (UT), magnetic particle testing (MT) and liquid penetrant testing (PT) four. [0003] Among them, after the pipeline is installed, it is often necessary to carry out non-destructive testing to prevent leakage incidents. However, the existing pipeline circumference flaw detection device needs manual detection, which is not only low in accuracy, but also labor-intensive and time-consuming. Contents of the invention [0004] Based on the deficiencies in the prior art mentioned in the background art above, th...
