Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection devices, in particular to a circumferential ray detection device for pipeline prefabricated parts. Background Art

[0002] Prefabricated pipelines refer to pipeline components prefabricated, processed and assembled in factories or production sites. After the production of prefabricated pipelines is completed, a circumferential ray detection device is required to detect the quality of the pipelines, so as to avoid the use of prefabricated pipelines with problems such as air holes, inclusions, cracks, etc. inside, and improve the project quality.

[0003] However, in the prior art, circumferential ray detection devices are divided into two categories: external installation and internal installation. When the circumferential ray detection device is externally installed on the pipeline, a large external working space is required. When the external installation operation space is insufficient or other situations occur, it is necessary to use an internally installed circumferential ray detection device to detect prefabricated pipelines. However, when the existing internally installed circumferential ray detection device enters the pipeline interior, it mostly uses a horizontal vehicle plate to fix and send the circumferential ray detection device to move and install the circumferential ray detection device. Due to the difference in the inner diameter sizes of the detected pipelines, when the circumferential ray detection device enters the interior and performs circular motion to scan the pipe wall, the distance between the ray emission end and the pipe inner wall is inconsistent, resulting in errors in the detection data of different positions when the circumferential ray detection device detects the pipeline. Summary of the Utility Model
