Abstract

The invention discloses a supporting arm of a pipeline detector, and belongs to the field of pipeline detection. The bottom of a probe groove included in a probe base of the supporting arm of the pipeline detector comprises a plurality of socket grooves, each socket groove is internally provided with a probe socket, the lower end of each eddy current probe in a plurality of eddy current probes comprises a contact pin, and through the contact pins, the eddy current probes can be connected with the probe sockets. Branch cables are connected to the bottoms of the probe sockets and connected withone end of a main cable, and the other end of the main cable can penetrate through a cable hole in the lower surface of the probe base. Therefore, in the embodiment of the invention, the electrifyingpoints of the plurality of eddy current probes are all positioned below the eddy current probes, the branch cable correspondingly connected with each probe socket is fixed in the probe base, and the cable connected with the probe is not exposed out of the probe base, so that the cable does not rub the pipe wall of the oil and gas pipeline, and the cable is not easy to damage.

Description

technical field [0001] The present application relates to the technical field of pipeline detection, in particular to a support arm of a pipeline detector and the pipeline detector. Background technique [0002] Oil and gas pipeline is one of the main equipment for transporting oil and natural gas. Oil and gas pipelines in long-term operation face risks such as pipe body corrosion and deformation, which requires regular inspection of oil and gas pipelines through pipeline detectors. [0003] In the related art, a pipeline detector includes a plurality of support arms, wherein, for any support arm, the support arm includes two parallel elastic swing arms and a probe base connected to one end of the two elastic swing arms. Wherein, a plurality of eddy current probes are installed on the probe base, and the energization point included on one side of each eddy current probe in the plurality of eddy current probes is connected with one end of one cable in the plurality of cables...
