A multi-section bridge pipeline welding seam positioning flaw detection device

Abstract

The invention discloses a multisection bridge pipeline welding seam positioning flaw detecting device. The multisection bridge pipeline welding seam positioning flaw detecting device comprises a first cavity-type end socket, a universal joint connector, a second cavity-type end socket, travelling mechanisms, an auxiliary mechanism, a gamma source accommodating and conveying positioning unit, and a light emitting unit; the travelling mechanisms are uniformly arranged on the periphery of the first cavity-type end socket and the periphery of the second cavity-type end socket; the auxiliary mechanism is arranged on the first cavity-type end socket; the first cavity-type end socket and the second cavity-type end socket are connected via the universal joint connector. The beneficial effects are that: the multisection bridge pipeline welding seam positioning flaw detecting device can be used for flaw detecting of pipelines of different diameters, application range is widened, transillumination accuracy is increased, telescopic functions are achieved, crossing of welding seams or obstacles can be realized, working efficiency is increased, the structure is simple, the multisection bridge pipeline welding seam positioning flaw detecting device is convenient to use, and reliability is high.

Description

technical field [0001] The invention relates to the technical field of bridge pipeline weld seam flaw detection, in particular to a multi-section bridge pipeline weld seam positioning flaw detection device. Background technique [0002] The length of the support arm on the multi-section flaw detection machine for the existing bridge pipeline welded joints is fixed, so that only one diameter of pipeline can be used for flaw detection, and the scope of use is small. When there is an obstacle, it is impossible to pass through, which reduces work efficiency. The cameras on the multi-section flaw detection machine used for the welded joints of bridges and pipelines are all fixed by bolts, which often makes the camera appear dead angle, and cannot fully record the positional relationship between the radiation source and the weld seam, reducing the flaw detection. quality. [0003] Flaw detection is also called "non-destructive testing", which is a technology to check whether ther...
