Embodiment 1

[0031] Such as figure 1 , figure 2 As shown, an on-site pipeline flaw detection device of the present invention includes a support frame, a track 6 and a traveling mechanism. The support frame is installed on the outer surface of the pipeline 1 to be tested, and the track 6 is installed on the support frame. The walking mechanism of the walking mechanism is located between the track 6 and the pipeline to be tested 1, and the support frame provides stable support for the whole device, especially to improve the support point for the track 6, and the combination of the track 6 and the running mechanism makes the X-ray machine 7 outside the pipeline to be tested 1 The surface is free to go around, 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 the fixed ring 3 is sleeved on the pipeline to be tested 1 Above,...

Abstract

The invention discloses a field pipeline flaw detection device and belongs to the technical field of flaw detection. The device comprises a supporting frame, a track and a traveling mechanism, wherein the supporting frame is installed on the outer surface of a pipeline to be detected, the track is installed on the supporting frame, and the traveling mechanism is located between the track and the pipeline to be detected. The device is reasonable in structural design, easy to manufacture, and capable of avoiding the construction of a detection platform special for an X-ray flaw detector so as to reduce engineering cost, achieving comprehensive flaw detection of pipeline welding seams, improving flaw detection efficiency greatly, accelerating work progress, and allowing detection staff to be away from the flaw detection area during flaw detection so as to reduce the harm of radiographic inspection to detection staff, so that engineering safety is guaranteed reliably.

Description

technical field [0001] The invention relates to the technical field of flaw detection, in particular to a field pipeline flaw detection 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 hurry, the installation and constr...
