Embodiment 1

[0033] Such as figure 1 , figure 2As shown, a rolling filming device for on-site pipeline flaw detection of the present invention includes a support frame, a running mechanism and a running mechanism. The support frame is installed on the outer surface of the pipeline 1 to be tested, and the running mechanism is installed on the support On the frame, the running mechanism is located between the running mechanism and the pipeline 1 to be tested, and the support frame provides stable support for the whole device, especially to improve the support point for the track 6 in the running mechanism. The combination of the running mechanism and the running mechanism makes X The X-ray machine 7 is free to go around on the outer surface of the pipeline 1 to be tested, which is convenient for the X-ray machine 7 to locate the flaw detection position and improve the flaw detection efficiency; the support frame includes a fixed ring 3, a fixed connection end 4 and a connecting rod 5, and t...

Abstract

The invention discloses a rolling photographing device for on-site pipeline flaw detection, and belongs to the technical field of flaw detection. The rolling photographing device comprises a supporting frame, a running mechanism and a walking mechanism, wherein the supporting frame is mounted on the outer surface of the pipeline to be detected; the running mechanism is mounted on the supporting frame; the walking mechanism is positioned between the running mechanism and the pipeline to be detected. The rolling photographing device for on-site pipeline flaw detection is reasonable in structural design and easy to manufacture; a special detection platform does not need to be built for an X-ray flaw detector, so that the engineering cost is reduced; furthermore, all-round flaw detection for pipeline welds is realized, the flaw detection efficiency is greatly improved, and the engineering progress is accelerated; meanwhile, a detection person can get away from a flaw detection region in the flaw detection process, so as to relieve the harm of ray flaw detection to the detection person and provide great insurance for the safety of the engineering.

Description

technical field [0001] The invention relates to the technical field of flaw detection, in particular to a rolling filming device for on-site pipeline flaw detection. Background technique [0002] Flaw detection is the detection of cracks and defects inside metal materials or components. Commonly used flaw detection methods include radiographic flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetrant flaw detection, eddy current flaw detection and other methods. Radiographic flaw detection is a non-destructive testing method that uses the difference in intensity attenuation of X-rays or γ-rays when penetrating each part of the inspected part to detect defects in the inspected part. [0003] During the construction process, in order to ensure the quality of the project, each weld must be subjected to non-destructive testing. The most commonly used flaw detection equipment is X-ray flaw detector. Since the construction is often in a hurry, the i...
