Device for fixing detection probe for ship pipeline

Abstract

The invention provides a device for fixing a detection probe for a ship pipeline. The length of the whole device is adjusted by a locking device on a lower rod; when the inner wall of the pipeline isdetected, sweeping and detection from bottom to top are performed; the elongation of a first telescopic rod is controlled by a controller, and a sweeper is enabled to be positioned on the inner wall of the pipeline; a hand lever is rotated for one circle, and the sweeper sweeps the inner wall of the pipeline for one circle and then continuously upwards sweeps; the elongation of a second telescopicrod is controlled by the controller, and the inner wall of the pipeline is detected by the detection probe; when the outer wall of the pipeline is detected, a first annular sleeve is rotated, so thatthe first telescopic rod and the second telescopic rod are positioned on the same vertical line, and the sweeping and detection from bottom to top are performed; the elongation of the first telescopic rod is controlled by the controller, the sweeper is enabled to be positioned on the outer wall of the pipeline, and the hand lever moves forwards for a distance; the sweeper sweeps the outer wall ofthe pipeline for a distance and continuously upwards sweeps; the elongation of the second telescopic rod is controlled by the controller, and the detection probe detects the outer wall of the pipeline.

Description

technical field [0001] The invention belongs to the field of ship pipeline detection, in particular to a device for fixing a ship pipeline detection probe. Background technique [0002] Non-destructive testing technology is to detect various engineering materials, parts, Internal and surface defects such as structural parts, and make judgments and evaluations on the type, nature, quantity, shape, shape, position, size, distribution and changes of defects. Non-destructive testing technology mainly includes five testing methods: radiographic testing, ultrasonic testing, magnetic particle testing, penetrant testing and eddy current testing, and pulsed eddy current testing technology, as a branch of eddy current testing in non-destructive testing, has its unique advantages, mainly including It has the advantages of no coupling agent, rich spectrum, fast response speed, and strong penetration depth. However, the pulsed eddy current detection device does not have a cleaning func...
