An adjustable protective device for pipeline flaw detector

Abstract

The invention relates to the field of pipeline flaw detectors, in particular to an adjustable protective device for pipeline flaw detectors, which includes a handle, a guide structure, a cleaning structure, a position limiting structure, a fixing structure, an ash removal structure and a transmission structure; Adjust the position of the four guide structures through the limit structure, so that the four guide structures can define a circle, so that the four guide structures are all in contact with the pipeline, which is convenient for use in the flaw detection of pipelines with different diameters, thereby greatly improving the flexibility of operation The four guiding structures are symmetrically arranged in the limit structure in pairs, which makes it more convenient and quick to drive the rotation between the limit structure and the pipeline, facilitates flaw detection at different positions of the pipeline, and facilitates the positioning of the guide structure after the flaw detection is completed. Then the flaw detection quality is greatly improved; the ash removal structure is connected to the fixed structure, so that the guide structure drives the transmission structure to compress the ash removal structure when guiding, so that the ash removal structure can clear the ash on the flaw detector on the fixed structure through gas.

Description

technical field [0001] The invention relates to the field of pipeline flaw detectors, in particular to an adjustable protective device for pipeline flaw detectors. Background technique [0002] The flaw detector is generally non-destructive flaw detection. The flaw detector is specially used for shipbuilding, petroleum, chemical industry, machinery, aerospace, transportation and construction and other industrial sectors to check the welding quality of materials and parts such as hulls, pipelines, high-pressure vessels, boilers, aircraft, vehicles and bridges. , and the quality of processed parts such as various light metals, rubber, ceramics, etc. In the case of performance, it is a method to detect various macroscopic defects inside or on the surface of materials, objects or equipment, and to judge their position, size, shape and type. [0003] However, when performing flaw detection on a pipeline that has been installed with a relatively high erection height, the traditio...

Problems solved by technology

[0003] However, when performing flaw detection on a pipeline that has been installed with a relatively high erection height, the traditional support structure is not convenient for supporting the flaw detection components, and it is not convenient for flaw detection at different positions of the erected pipeline, and during high-altitude operations It is easy to cause the flaw detection component to fall and damage, and the dust on the pipeline is easy to stick to the end of the flaw detection equipment during the flaw detection process, which affects the quality of flaw detection, and it is not convenient to clean up the dust and waste accumulated on the pipeline during the flaw detection process. And it is not convenient to locate the distance between the flaw detector and the pipeline
