Description

Technical Field

[0001] The invention relates to the technical field of flaw detectors, in particular to an adaptive pipeline X-ray flaw detector. Background Art

[0002] With the widespread application and multi-dimensional development of non-destructive testing, non-destructive testing is becoming more and more specialized, classified, refined and widely used in different fields, with more diversified requirements for time, space, testing conditions and testing efficiency. However, due to the characteristics of its field, non-destructive testing often has various forms and complex flaw detection situations, which makes it difficult to achieve both research and development and production of flaw detectors. Its products are often difficult to be compatible with different flaw detection situations, resulting in a strong correspondence in the application fields of flaw detectors, thereby reducing the use efficiency of flaw detectors. Especially in the field of pipeline flaw detection, the existing X-ray flaw detectors are difficult to handle flaw detection of different pipelines, and often a flaw detector of one specification is only suitable for pipelines of one specification. An adaptive pipeline X-ray flaw detector proposed according to application number 201620222911.3 includes an X-ray generator, an adjustment mechanism, a track foot, a heat energy converter, a battery and a drive motor. The heat conductor in the X-ray generator connects the X-ray tube and the casing, and the X-ray tube passes through the heat conductor and is fixed in the radiator. The adaptive pipeline X-ray flaw detector has complex operation, low flaw detection efficiency, low transportation flexibility, small angle for curved pipelines, and poor use effect.

[0011] Furthermore, it also includes a connecting rod and a roller, and the rollers are respectively connected to the lower surface of the four corners of the mounting plate by the connecting rod. The setting of the connecting rod and the roller improves the flexibility of the flaw detector, and the use effect is more in line with the requirements of the actual site.

[0012] Furthermore, it also includes heat dissipation grooves, which are arranged in an array on the upper surface of the contact plate equipped with the ray emitting plate, so that the heat generated by the ray emitting plate can be dissipated through the heat dissipation grooves.

[0013] Compared with the prior art, the invention has the following advantages:

[0014] 1. The adaptive pipeline X-ray flaw detector adopts spring bidirectional shock absorption and a shaft connection design with a wide steering angle, which can improve the adaptability range of the use site and has a wide coverage of the diameter and bending angle of the pipeline.
