Wheel set flaw detector capable of adjusting wheel track of walking mechanisms

Abstract

The invention relates to the field of flaw detectors, in particular to a wheel set flaw detector capable of adjusting the wheel track of walking mechanisms. The wheel set flaw detector comprises a flaw detection mechanism, an adjusting mechanism, two walking mechanisms, a sweeping mechanism and a driving mechanism, wherein the walking mechanisms are oppositely mounted at two ends of the flaw detection mechanism; the two walking mechanisms are allowed to approach or depart from each other by utilizing the opening and closing principles of ribs; as the two walking mechanisms are contracted, thewhole wheel set flaw detector can be placed in a pipeline to be detected; and the walking mechanisms have a telescopic function, and the two walking mechanisms are loosened after being put into the pipeline to be detected, so the ends of the walking mechanisms abut against the pipeline. According to the invention, the wheel track is rapidly adjusted according to pipelines with different diameters;the whole structure of the wheel set flaw detector is guided, and the situation that the whole structure inclines during walking and the detection of pipelines is affected is avoided; when the wholestructure is placed into a pipeline needing to be detected and then rotates clockwise, expansion of the two walking mechanisms is achieved, so operation is easy; and the expansion of the two walking mechanisms is controlled at the same time, so wheel track adjusting time is saved.

Description

technical field [0001] The invention relates to the field of flaw detectors, in particular to a wheel set flaw detector capable of adjusting the track of a traveling mechanism. 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 show the surface and internal defects of parts and welds processed from materials to evaluate the quality of products. Shows the location, shape and size of the discontinuity. It can detect extremely fine cracks, hairlines, white spots, folds, inclusions and other defects on the surface of the material. It has high detection sensitivity and can intuitively display the position, shape, size and severi...

Problems solved by technology

[0003] However, when the flaw detector detects the pipeline to be inspected, the flaw detector body is directly put into the pipeline to be inspected. It is difficult for the running wheels of the machine to adjust the wheelbase according to the pipes of different diameters. When inspecting pipes of different diameters, the flaw detector is prone to tilt, causing the flaw detector to stagnate or roll over inside the pipe, which affects the detection effect of the pipe. When the machine detects the pipeline, the overall movement cooperates with the detection of the flaw detector. If the pipeline encounters dust, it will affect the detection effect of the flaw detector.
