Description

Automatic crawling scanning nondestructive flaw detection device for inner holes Technical Field The utility model relates to the field of pipeline inner hole detection, in particular to an automatic inner hole crawling scanning nondestructive flaw detection device. Background The pipeline is used as important equipment for transporting flowing media, is widely applied to industries such as petroleum, chemical engineering, electrician and the like, and therefore, a large number of service pipelines are provided, however, manufacturing defects possibly exist in the pipeline and complicated and various faults are easily caused in service due to the influences of flushing of the flowing media, environmental corrosion, external force damage and the like, serious economic loss and even serious safety accidents are caused, if the problems can be found as soon as possible, and corresponding measures are taken, accidents can be avoided, and failure modes of the pipeline have the problems of local corrosion, integral corrosion, large-scale damage corrosion, sulfide stress corrosion, stress corrosion cracking, mechanical damage and the like, so that the automatic crawling scanning nondestructive flaw detection device for the inner holes is required to solve the problems. Disclosure of utility model The utility model aims to provide an automatic crawling scanning nondestructive flaw detection device for an inner hole so as to solve the problem that an oil film influences ultrasonic judgment. The technical scheme is that the automatic crawling scanning nondestructive flaw detection device for the inner hole comprises a detection ring for detecting the inner hole of a pipeline, wherein the detection ring is in an annular arrangement, a feeding inner cavity for oil film to pass through is formed in the inner side of the detection ring, a scraping ring is arranged on one side of the detection ring, a turning ring is fixedly arranged in the inner side of the feeding inner cavity, and the end part of the turning ring is fixedly connected with the end part of the scraping ring; the inner side of the feeding inner cavity far away from the turning ring is fixedly provided with a feeding isolation ring, and the outer sides of the feeding isolation ring and the scraping ring are contacted with the inner wall of the inner hole of the pipeline; The end part of the detection ring corresponding to the scraping ring is fixedly provided with a first ultrasonic detection ring, and the outer side of the detection ring is fixedly provided with a second ultrasonic detection ring.
