Technical field
The present invention relates to a kind of sensor, specifically a kind of wire rope magnetic line of force balanced type flaw detection sensor.
Background technology
In mine, each field such as cableway, hoisting device, elevator, harbour machinery, rope bridge all needs to use wire rope flaw detection sensor.
At present, the principle of work of domestic existing wire rope flaw detection sensor, for detecting wire rope leakage field situation after magnetization wire rope, judges the defect of wire rope; Mainly can sort out two kinds: one is weak magnetic detection, as Luoyang TCK and TST; Another kind is strong magnetic detection, as Shanghai and China and the wire rope flaw detection sensor of HUST.And the maximum shortcoming that they exist is: the first, the homogeneity existing problems of magnetization wire rope, and cause measurement inaccurate; The second, due to the shake of wire rope, the leakage field size that wire rope flaw detection sensor is received can change, and causes measurement inaccurate, and then causes the detection of the inner fracture of wire situation of wire rope to produce difficulty.
Summary of the invention
Object of the present invention is just to provide a kind of wire rope magnetic line of force balanced type flaw detection sensor, all defect of the measuring steel wire rope inside and outside of accurate non-blind area, overcomes the impact of wire rope shake on measurement result.
The technical scheme that the present invention is adopted to achieve these goals is: a kind of wire rope magnetic line of force balanced type flaw detection sensor, is characterized in that: comprise inductor, check processing circuit, output driving circuit, CAN change-over circuit and feed circuit; Inductor is connected with check processing circuit, and check processing circuit is connected with output driving circuit, and output driving circuit is connected with CAN change-over circuit, and feed circuit are connected with inductor, check processing circuit, output driving circuit and CAN change-over circuit respectively; Described inductor is provided with driving source, two drive coils and an inductive coil, described driving source is connected with two drive coils respectively, produce the magnetic line of force that size equidirectional is contrary, described inductive coil is arranged in the middle of two drive coils, and the output terminal of inductive coil is connected with described check processing circuit.
The invention has the beneficial effects as follows: the sensitivity of the extent of damage inside and outside detection wire rope is greatly improved, when the every filament diameter of wire rope is greater than 1mm, can measure for disconnected one.Avoiding shaking the impact on measuring simultaneously, greatly improving the accuracy of wire rope standard, improve tested wire rope safety in utilization, guarantee production efficiency and the security of the lives and property of the entity and individual using wireline equipment; The present invention is high in technological content, technological precedence, and working stability is reliable, usage range is wide, make measurement sensistivity, accuracy significantly rises to, the easier and accurate damage situation that must find wire rope, in technique, adopt up-to-date and state-of-the-art components and parts, modular construction, make sensor stabilization reliable, easy care, considers the complex environment of application places to greatest extent, get rid of on-the-spot interference, reach steady operation.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated:
A kind of wire rope magnetic line of force balanced type flaw detection sensor, as shown in Figure 1, comprises inductor, check processing circuit, output driving circuit, CAN change-over circuit and feed circuit; Circuit connects as shown in Figure 3 and Figure 4, the signal output part of inductor is connected with check processing circuit, check processing circuit is connected with output driving circuit, output driving circuit is connected with CAN change-over circuit, feed circuit are connected with inductor, check processing circuit, output driving circuit and CAN change-over circuit respectively, for various piece is powered; The principle of work of described inductor as shown in Figure 2, inductor is provided with driving source 1, drive coil A2 and a drive coil B3 and inductive coil 4, described driving source 1 is connected with drive coil A2 and B3 respectively, produce the identical and magnetic line of force that direction is contrary of size, described inductive coil 4 is arranged on the centre of two drive coil A2 and B3, and inductive coil output terminal 5 is connected with described check processing circuit.Driving source 1 can adopt direct current or AC power, the magnetic line of force equal and opposite in direction direction that during work, drive coil A2 and B3 produces is contrary, in inductive coil 4, produce induced electromotive force is zero, is no matter wire rope shake and mobile, on the induced electromotive force of inductive coil 4 without impact.When wire rope is impaired, as fracture of wire, deformation, wearing and tearing, steel wire extruding, rope neck local becomes large, wire rope is crushed, reverse, bending etc., first through drive coil A2, its magnetic flux is changed, break magnetic flux balance, in inductive coil, produce induced electromotive force+E; When defect in rope is through drive coil B3, cause drive coil B3 magnetic flux change, in drive coil B3, produce induced electromotive force-E.Wire rope inherent vice or External Defect all can cause the change of magnetic flux, thus accurately detect steel rope fault, equilibrium principle ensure that high measurement sensistivity and measuring accuracy, and whole rope has one to rupture or diameter change 2mm just can be accurately detected out.
When inductor detects that magnetic flux changes, output signal to check processing circuit, check processing circuit outputs to output driving circuit after carrying out direct current amplification, judgement and computing to signal, the signal that output driving circuit exports is through the conversion of CAN change-over circuit, and providing can the signal of measured terminating machine identification.
