Description
Technical field
The utility model relates to a kind of degaussing gear, especially relates to a kind of pipeline remanent magnetism belt degaussing gear.
Background technology
In petrochemical plant maintenance and process pipelines welding procedure, welding rod will be by strong adsorption to pipeline with a certain distance from bevel for welding, the reversing the current magnetic field that produces after the welding rod striking during welding and remanent magnetism magnetic field interaction make electric arc blow outside groove, can't form molten bath and weld seam, make under the band magnetic state and can not implement pipeline welding.At present, the field condition construction utilizes electromagnetic induction principle to carry out demagnetization often, according to the remanent magnetism size, utilize on-the-spot electric welding machine electrode holder line interim coiling anti-magnetized coil 10-20 circle on pipeline opening, welding machine dc power cathode ground connection, soldering turret is clamped welding rod striking on ground wire, treats that whole root bead bar all burnt demagnetization finishes.Although this technique can be implemented welding at the scene, because the electrode holder linear diameter is thicker, the erasing current that passes through is large (100A), makes every demagnetization once will burn a root bead bar, and namely consumable material, waste again electric energy; Scene needs the regular hour with electrode holder wire-wound anti-magnetized coil processed simultaneously, takies the construction period; The weld bond pipeline of magnetic of disappearing in construction all can produce new remanent magnetism at any time under electromagnetic environment, therefore need to repeatedly carry out demagnetization.
The utility model content
To have consumable material, waste electric energy in order overcoming in existing petrochemical pipe Site Welding, extend the construction period, to need the deficiency of demagnetization repeatedly, the utility model provides a kind of pipeline remanent magnetism belt degaussing gear.
The technical scheme that its technical problem that solves the utility model adopts is: pipeline remanent magnetism belt degaussing gear, comprise annulus, coil is coated with insulating barrier, and the loop coil that is coated with insulating barrier is arranged in the pocket bag, and the snap close that is arranged on the pocket bag is closed the pocket bag; Stretch out outside the pocket bag at the two ends of loop coil coiling, and an end of coiling is connected with the wiring female joint, and the other end is connected with the wiring male joint; Pocket bag more than 2 or 2 is fixedly mounted on the strip waistband successively, and the loop coil in the pocket bag more than 2 or 2 is successively by wiring female joint, wiring male joint series connection; The two ends of strip waistband are equipped be used to the cotton rope that is connected and fixed.The pocket bag is fixedly connected with waistband by sewing line; Toroidal end face is attached on the plane of waistband.Loop coil is cuboid or square.
The beneficial effects of the utility model are, and are simple in structure, easy to use, can simplify the demagnetization program, make pipeline demagnetization simple operation, shorten the pipeline welding duration, improve pipeline welding quality and operating efficiency.

Fig. 2 is the top view of Fig. 1.
In figure: 1. loop coil, 2. wiring female joint, 3. wiring male joint, 4. insulating barrier, 5. pocket bag, 6. snap close, 7. cotton rope, 8. sewing line, 9. strip waistband.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.But what those skilled in the art should know is that the utility model is not limited to the listed specific embodiment, as long as spirit according to the invention all should be included in protection scope of the present invention.
Referring to accompanying drawing 1.The utility model pipeline remanent magnetism belt degaussing gear, comprise pocket bag 5, strip waistband 9, annulus 1, and annulus 1 is coated with insulating barrier 4, and the loop coil 1 that is coated with insulating barrier 4 is arranged in pocket bag 5, and the snap close 6 that is arranged on pocket bag 5 is closed pocket bag 5.
Stretch out outside pocket bag 5 at the two ends of loop coil 1 coiling, and an end of coiling is connected with wiring female joint 2, and the other end is connected with wiring male joint 3; The quantity of pocket bag 5 is more than 2 or 2, according to the length of institute's welded pipe line circumference, determines.Pocket bag 5 is fixedly mounted on strip waistband 9 successively, usually with sewing line 8, pocket bag 5 is made and is fixed on waistband 9.Loop coil 1 is cuboid or square; The end face of loop coil 1 is attached on the plane of waistband 9.Loop coil 1 in pocket bag 5 is successively by wiring female joint 2, wiring male joint 3 series connection.
The two ends of strip waistband 9 are equipped be used to the cotton rope 7 that is connected and fixed.
The utility model pipeline remanent magnetism belt degaussing gear also can adopt in a pocket bag 5 annulus 1 that is equipped with successively more than 2 or 2, and series connection successively; Need the isolation of pocket bag between adjacent 2 annuluses 1.
The utility model develops according to electromagnetic induction principle, adds an equal-sized backing field on former residual magnetic field, makes the workpiece part not show magnetic.Though the method can not make workpiece forever demagnetize, can guarantee temporarily without macroscopic magnetization, to show in work progress, welding job is normally carried out, simplify the demagnetization program, shorten the erasing time, simple and convenient, improve welding quality and operating efficiency.
When application the utility model carries out the pipeline welding operation, the quantity of at first according to pipe circumference length, determining to install pocket bag 5 on waistband 9, the end face of the interior loop coil 1 of pocket bag 5 is facing to waistband 9, and several loop coils 9 are connected in series; Then, the belt demagnetizer is after the pipeline opening circumferencial direction of needs welding winds with one circuit, fixing with cotton rope 7; Subsequently, with magnetometer or compass, pipe joint remanent magnetism being carried out magnetic pole detects, determine belt type demagnetizer energising direction according to the pole polarity that detects with Ampere's law, the negative level of dc welding machine weld handle plier is clipped on first lead-in wire of the female wiring of demagnetizer, the anodal weld handle plier of dc welding machine is clamped a bare conductor to be touched on another root male joint lead-in wire of belt demagnetizer, the time of touching, the electric welding machine output dc voltage was not less than 75V less than 5 seconds, and welding current is not less than 100A.
