Embodiment 1

[0035] Such as figure 1 , figure 2 , image 3As shown, a mobile 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 On the support frame, the running mechanism is located between the running mechanism and the pipeline 1 to be tested. 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 The X-ray machine 7 is free to circle around the outer surface of the pipeline 1 to be tested, which is convenient for the X-ray machine 7 to find 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, a...

Abstract

The invention discloses a movable shooting device for on-site pipeline flaw detection and belongs to the technical field of flaw detection.The movable shooting device comprises a supporting frame, a running mechanism and a traveling mechanism, the supporting frame is mounted on the outer surface of a to-be-detected pipeline, the running mechanism is mounted on the supporting frame, and the traveling mechanism is positioned between the running mechanism and the to-be-detected pipeline.The movable shooting device is reasonable in structural design, setting up of a detection platform special for an X-ray flaw detector can be avoided, engineering cost is reduced, and omnibearing flaw detection of pipeline welding joints is realized; when flaw detection is performed on welding joints on a same pipeline, trouble of repeated mounting and demounting is omitted, flaw detection efficiency is improved greatly, engineering process is accelerated, detection personnel can be away from a flaw detection area in the flaw detection process, damage to the detection personnel by ray flaw detection is reduced, and a powerful guarantee is provided for engineering safety.

Description

technical field [0001] The invention relates to the technical field of flaw detection, in particular to a movable 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...
