Adjustable protecting device for pipeline flaw detector

Abstract

The invention relates to the field of pipeline flaw defectors and in particular to an adjustable protecting device for a pipeline flaw detector. The protecting device comprises a handle, four guidingstructures, a cleaning structure, a limiting structure, a fixing structure, an ash removing structure and a transmission structure. The positions of the four guiding structures are adjusted by the limiting structure conveniently, so that the four guiding structures determine a circle and lean against a pipeline to be applied to flaw detection of pipelines with different diameters conveniently, andtherefore, the operating flexibility is improved greatly. The four guiding structures are symmetrically arranged on the limiting structure in pairs, so that it is more convenient and rapid to drive rotation between the limiting structure and the pipeline. Flaws in different positions of the pipeline are detected conveniently. After flaw detection, the guiding structures are positioned conveniently, so that the flaw detection quality is improved greatly. The ash removing structure is connected to the fixing structure, so that the guiding structures drive the transmission structure to compressthe ash removing structure during guiding, and therefore, the ash removing structure cleans ash on the flaw detector on the fixing structure by means of 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.

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
