A mobile on-site X-ray pipeline rolling filming device

Abstract

The invention discloses a movable field X-ray rolling shooting device for a pipeline, and belongs to the technical field of flaw detection. The movable field X-ray rolling shooting device for the pipeline comprises a supporting frame, an operating mechanism and a walking mechanism, wherein the supporting frame is mounted on the external surface of a to-be-detected pipeline; the operating mechanism is mounted on the supporting frame; the walking mechanism is located between the operating mechanism and the to-be-detected pipeline. The movable field X-ray rolling shooting device for the pipeline, which is provided by the invention, is reasonable in structural design and is simple to make; not only can the special putting up of a detecting platform for an X-ray flaw detector be avoided and can the engineering cost be reduced, but also the all-around flaw detection for welds on the pipeline is realized; when the flaw detection is carried out on the welds on the same pipeline, the trouble of repeated disassembly and assembly is omitted; the flaw detection efficiency is greatly promoted; the engineering progress is quickened; a detector is enabled to keep far away from an area to be subjected to the flaw detection in a flaw detection process; the injury of radiographic flaw detection to the detector is reduced; a strong guarantee is provided for engineering safety.

Description

technical field [0001] The invention relates to the technical field of flaw detection, and more specifically relates to a movable on-site X-ray pipeline rolling filming device. 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 h...
