Description

Technical Field

[0001] The invention relates to the technical field of gas and oil pipeline defect detection equipment, and in particular to an auxiliary installation device for a pipeline defect detector. Background Art

[0002] The magnetic flux leakage detector is used for internal and external damage defect detection of gas and oil pipelines. During the detection, the magnetic flux leakage detector needs to be placed in a transmitting and receiving ball barrel, and the magnetic flux leakage detector is moved in the pipeline to perform an all-round and no-dead-angle detection of the inner wall of the pipeline. This method can accurately detect corrosion, cracks, deformation and other defects on the inner wall of the pipeline, and locate and quantitatively evaluate them. In the existing operating steps, when the magnetic flux leakage detector is placed in the transmitting and receiving ball barrel or taken out of the transmitting and receiving ball barrel, due to the structure and weight limitations of the magnetic flux leakage detector, multiple people are required to lift it together and slowly insert it into the transmitting and receiving ball barrel. The operation is extremely inconvenient and the operator may be accidentally injured. Its convenience and safety need to be improved. In addition, since there may be excessive pressure in the transmitting and receiving ball barrel, accidents may also occur when the operator opens the blind plate, which needs to be improved urgently.
