Embodiment Construction

[0024] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0025] For the convenience of description, spatially relative terms may be used here, such as "on ...", "over ...", "on the surface of ...", "above", etc., to describe the The spatial positional relationship between one device or feature shown and other devices or features. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, devices described as "above" or "above" other devices or configurations would then be oriented "beneath" or "above" the other devices or conf...

Abstract

The invention discloses a manual ultrasonic detection device for large pipe diameters. The manual ultrasonic detection device comprises an ultrasonic phase control array detector, a creeping wave probe and a mounting rack, wherein the creeping wave probe is mounted on a creeping wave probe wedged block; the ultrasonic probe of the ultrasonic phase control array detector is mounted on an ultrasonicprobe wedged block; the ultrasonic phase control array detector is connected with the creeping wave probe and the ultrasonic probe through data wires; the mounting rack consists of a limiting rod andtwo pressing rods; one ends of the two pressing rods are hinged together; the other ends of the pressing rods are respectively hinged to the creeping wave probe wedged block; the ultrasonic phase probe wedged block is fixed on the limiting rod; and the limiting rod is arranged between the two pressing rods in a sliding manner. The manual ultrasonic detection device for large pipe diameters, whichis disclosed by the invention, is simple in structure, simple to operate and high in detection rate.

Description

technical field [0001] The invention relates to the technical field of ultrasonic flaw detection, in particular to a manual ultrasonic detection device for large pipe diameters. Background technique [0002] Ultrasonic creeping wave is a compressed longitudinal wave with a refraction angle of 90°. The maximum amplitude direction is at a small angle with the surface, and it only propagates under the surface. The surface scattering is relatively weak, and it is not sensitive to surface roughness. It is especially suitable for detecting austenite coarse grains. Inspection of material surface, near-surface defects and defects in thin parts, such as subsurface defect cracks in castings, surfacing layers, etc., and cracks at the root of bolts, etc. [0003] In the process of ultrasonic detection, the emission and reception of ultrasonic waves are realized through the probe. The performance of the probe directly affects the characteristics of the ultrasonic wave and affects the de...
