Abstract
The utility model aims to provide a steel pipe flaw detection device. The steel pipe flaw detection device comprises a working table, wherein a guide rail is arranged on the working table; a trolley capable of moving on the guide rail is arranged on the guide rail; the guide rail sequentially penetrates through a magnetization chamber, a powder spray chamber, a flaw detection chamber and a demagnetization chamber; the heights and the widths of the magnetization chamber, the powder spray chamber, the flaw detection chamber and the demagnetization chamber can allow the trolley loaded with pipelines to pass; and magnetic powder media sprayed from the powder spray chamber can be black magnetic powder, red magnetic powder or white magnetic powder. The steel pipe flaw detection device has the benefits as follows: the structure is simple, the use is convenient, magnetization, flaw detection and demagnetization of a workpiece can be completed on the same working table, and accordingly, manpower is saved.
Description
Technical field
The utility model relates to a kind of pipeline sniffer, particularly relates to a kind of pipeline inspection device.
Background technology
Magnetic powder inspection utilizes the stray field at workpiece, defect place and the interaction of magnetic, it has utilized the difference of steel product surface and near surface flaw magnetic permeability and iron and steel magnetic permeability, after magnetization, will distort in the magnetic field at these material discontinuity places, forming section flux leakage place surface of the work has produced stray field, thereby attract magnetic to form the magnetism powder accumulation of fault location, under suitable illumination condition, show defective locations and shape, the accumulation of these magnetics is observed and explained, just realized magnetic powder inspection.Existing pipeline sniffer has been the flaw detection of twin conduit, and the demagnetization of pipeline is just completed by other staff, does like this and extremely wastes resource.Therefore, be necessary existing pipeline sniffer to improve, can on same worktable, complete magnetization, flaw detection and the demagnetization of workpiece, saved manpower.
Utility model content
In order to overcome the weak point of existing pipeline sniffer, the utility model provides a kind of pipeline inspection device.
The technical solution of the utility model is achieved in that
A kind of steel pipe defectoscope of this programme, comprises worktable, on described worktable, is provided with guide rail; On described guide rail, be provided with the dolly that can move on guide rail; Described guide rail is successively through magnetization chamber, powder spraying chamber, crack detection room and demagnetization chamber; The height of described magnetization chamber, powder spraying chamber, crack detection room and demagnetization chamber and width can pass through for the dolly that is mounted with pipeline.
Further, the magnetic medium that described powder spraying chamber sprays can be black particle, red particle or white magnetic.
Further, described degaussing process, for part is put in DC electromagnetic field, constantly changes direction of current and gradually electric current is down to null value.
Usefulness of the present utility model is: simple in structure, easy to use, can on same worktable, complete magnetization, flaw detection and the demagnetization of workpiece, and saved manpower.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1-worktable, 2-guide rail, 3-dolly, 4-magnetization chamber, 5-powder spraying chamber, 6-crack detection room, 7-demagnetization chamber.
Embodiment
Below in conjunction with accompanying drawing, a kind of embodiment of the present utility model is made to brief description.
A kind of steel pipe defectoscope as Fig. 1, comprises worktable 1, on described worktable 1, is provided with guide rail 2; On described guide rail 2, be provided with the dolly 3 that can move on guide rail 2; Described guide rail 2 is successively through magnetization chamber 4, powder spraying chamber 5, crack detection room 6 and demagnetization chamber 7; The height of described magnetization chamber 4, powder spraying chamber 5, crack detection room 6 and demagnetization chamber 7 and width can pass through for the dolly 3 that is mounted with pipeline; The magnetic medium that described powder spraying chamber 5 sprays can be black particle, red particle or white magnetic.
The course of work of this example: when using the utility model, first, the pipeline that will detect a flaw is placed on the dolly 3 of worktable 1, owing to being provided with guide rail 2 on worktable 1, so dolly 3 can drive pipeline to move on worktable 1.Then, dolly 3 transports pipeline to magnetization chamber 4, workpiece is magnetized in magnetization chamber 4, pipeline after magnetization has entered powder spraying chamber 5, workman can select the magnetic medium that will spray according to the background color of pipeline, by the pipeline of the upper magnetic medium of spray, entered crack detection room 6 and detect a flaw, last, the qualified device for cleaning pipeline of detecting a flaw is crossed demagnetization chamber 7 and is carried out demagnetization.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
