Abstract
The utility model discloses a kind of flexible magnetic yoke device, comprise multistrand rope, conductive coil, two pieces of ferromagnetic boots, pitch angles adjustment control device, be fastened outside the middle part of multistrand rope conductive coil; Two end faces of multistrand rope fix one piece of ferromagnetic boots respectively; The two ends of multistrand rope are bent to middle part, install between the two ends of multistrand rope upon bending and fix pitch angles adjustment control device, pitch angles adjustment control device can control bending after the ferromagnetic boots in multistrand rope two ends between spacing and ferromagnetic boots bottom surface between relative angle.The utility model can meet the defects detecting technology requirement of different magnetic boots spacing and different coupling angle in fracture detection by magnetic powder.
Description
Technical field
The utility model relates to a kind of the cannot-harm-detection device, particularly relates to a kind of flexible magnetic yoke device of fracture detection by magnetic powder.
Background technology
General fracture detection by magnetic powder electromagnetic yoke all adopts silicon steel sheet to form as the iron core system of changing, and the method electromagnetic conversion efficiency is high, loss is little, but brings thus and not easily adjust with the coupling gap of surface of the work, cannot reach optimum detection effect.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art, designs a kind of flexible magnetic yoke device, adopts multistrand rope to make flexible electrical yoke.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of flexible magnetic yoke device, it is characterized in that, comprises multistrand rope, conductive coil, two pieces of ferromagnetic boots, pitch angles adjustment control device; Be fastened outside the middle part of described multistrand rope conductive coil; Two end faces of multistrand rope fix one piece of ferromagnetic boots respectively; The two ends of multistrand rope are bent to middle part, install between the two ends of multistrand rope upon bending and fix pitch angles adjustment control device, described pitch angles adjustment control device can control bending after the ferromagnetic boots in multistrand rope two ends between spacing and ferromagnetic boots bottom surface between relative angle.
The beneficial effects of the utility model are, a kind of flexible magnetic yoke device, adopt multistrand rope to make flexible electrical yoke, the spacing between two magnetic boots of flexible yoke and angle can regulate arbitrarily, meet the defects detecting technology requirement of different magnetic boots spacing and different coupling angle in fracture detection by magnetic powder.
Below in conjunction with embodiment, the utility model is described in further detail, but a kind of flexible magnetic yoke device of the present utility model is not limited to embodiment.
