Abstract
A portable yoke defectoscope for yoke adjustable angle, comprises magnetic powder flaw detector main frame (1), is positioned at the metal yoke (2) of magnetic powder flaw detector main frame (1) bottom, is located at the yoke angular adjustment shift knob (3) on main frame top, is located at magnetic field generation shift knob (4) of main frame bottom, the power lead (5) be connected on main frame.The utility model devises a kind ofly has the portable yoke defectoscope of the Magnetic testing of adjustable yoke angle, for yoke method magnetic powder inspection, the accuracy of angular adjustment can be significantly improved, reduce labor intensity, increase the security to personnel in Magnetic testing process.
Description
Technical field
The utility model relates to a kind of portable yoke defectoscope of Magnetic testing with adjustable yoke angle, for yoke method magnetic powder inspection.
Background technology
Yoke defectoscope, utilize yoke to carry out magnetized light miniature magnetic particle inspection apparatus to the workpiece that ferrimagnet is made, can magnetize various part, be applicable to oil field, shipbuilding, internal combustion engine part, colliery, machinery, standard component, oil pump nozzle, aircraft manufacturing, auto parts, bridging, chemical industry, boilers and pressure vessel, the industry products such as railway, because of forging and stamping, quenching, welding, the surface that fatigue etc. causes and near surface flaw, as chain bar, bent axle, bearing, high-strength bolt, spring, forging, petrochemical industry pipe fitting, valve, blade, gear, roll, the flaw detection of the complex geometry such as anchor chain and weld seam workpiece.
All electronic components of alternating current-direct current yoke magnetic powder flaw detector and parts, be all arranged in main frame, generally can not come off, and circuit adopts colour cord to draw, and is convenient to distinguish, maintenance.Whole instrument layout is reasonable, and compact conformation is reasonable in design, uses easy to operate, the weight balancing of complete machine, easy to carry.
When using traditional yoke defectoscope to carry out magnetic powder inspection, when especially carrying out the weld seam detection of boiler and pressure vessel, need according to the width of weld seam (on such as steam boiler safety valve base and reheater piping weld seam wider, and the weld seam of main steam pipe and little base is narrower) namely the width that carrys out manual adjustments yoke magnetize the size of pole span, and the scope that general yoke defectoscope can regulate is at 50mm to 200mm.Manual adjustments has following inferior position: one is when carrying out water base magnetic powder inspection, due to a lot of moisture residual in yoke, the angle between yoke is regulated when inserting AC power, often there will be and leak electricity and situation electric in one's hands, although magnetic powder flaw detector is protected with leak resistance, often by light current in one's hands be also beyond affordability; Two is when pulling yoke, if the operating switch and the magnetic field that have touched defectoscope bottom because of carelessness produce shift knob (4), powerful magnetic field of short durationly can be applied to people on hand, will produce greatly disorderly to the blood of inside of human body and electrolytic solution, harm staff health of human body; Three is when pulling yoke, is difficult to settle at one go play the part of suitable angle, often needs to pull back and forth, finds most suitable angle to adapt to the width of weld seam, therefore can cause expending of the reduction of detection efficiency and testing staff's muscle power; Four is when carrying out the flaw detection of oiliness black particle, can leave a lot of dirty oil on hand, inconvenient wiping when pulling yoke; Five is after often pulling yoke, because the strength of different people is different with the angle of exerting oneself, can cause loosening of yoke screwing, even a yoke drops suddenly in the process pulled, and very easily hurts the personnel of below and lead to major accident when work high above the ground.
Summary of the invention
The drawback that the purpose of this utility model produces when being the angle being to solve manual adjustments yoke, realizes the portable yoke defectoscope that can use adjustable yoke angle function when carrying out Magnetic testing on the weld seam such as boiler and pressure vessel.
The utility model solves the technical scheme that its technical matters adopts:
A portable yoke defectoscope for yoke adjustable angle, comprises magnetic powder flaw detector main frame, is positioned at metal yoke bottom magnetic powder flaw detector main frame, is located at the yoke angular adjustment shift knob on main frame top, is located at the magnetic field of main frame bottom and produces shift knob, the power lead be connected on main frame.All electronic components and each spare and accessory parts and control circuit are arranged on main frame inside.
The utility model devises a kind ofly has the portable yoke defectoscope of the Magnetic testing of adjustable yoke angle, for yoke method magnetic powder inspection.The utility model can make nondestructive testing personnel when carrying out yoke method magnetic powder inspection, the expanded angle of Electronic control yoke is carried out by yoke angular adjustment shift knob, development rate is set to comparatively slow, thus can precisely find the yoke angle of the most applicable weld width to detect.Thus the accuracy of angular adjustment can be significantly improved, reduce labor intensity, increase the security to personnel in Magnetic testing process.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Number in the figure 1. magnetic powder flaw detector main frame, 2. metal yoke, 3. yoke angular adjustment shift knob, 4. magnetic field produces switch, 5. power lead, 6. electronic component and each spare and accessory parts, 7 control circuits.
Embodiment
See Fig. 1, a portable yoke defectoscope for yoke adjustable angle, comprises magnetic powder flaw detector main frame 1, is positioned at metal yoke 2 bottom magnetic powder flaw detector main frame 1, is located at the yoke angular adjustment shift knob 3 on main frame top, is located at the magnetic field of main frame bottom and produces shift knob 4, the power lead 5 be connected on main frame; It is inner that all electronic components and each spare and accessory parts 6 and control circuit 7 are arranged on main frame 1.
Magnaflux of the present utility model in use, the width that can come between motorized adjustment yoke according to the developed width of working site weld seam, "+,-" button and the yoke angular adjustment shift knob 3 on the top of pressing magnetic powder flaw detector 1 is only needed in the process regulated, during angular adjustment between yoke and pair of magnetic yoke 2 around its root reverse rotation time, the speed arranging expansion is comparatively slow, is convenient to precisely control required angle.When carrying out the angular adjustment of yoke, default setting magnaflux starting switch 4 is in closed condition always, inconvenience is caused with mistaken collision preventing, only when angle adjusting button 3 is in inoperation, just can open starting switch 4 and carry out Magnetic testing work, equally starting switch 4 to be pressed by staff be generally press starting switch with middle finger after hand catches magnetic powder flaw detector time, angle adjusting button 3 is in closed condition, with mistaken collision preventing.
Claims (1)
