Description
Technical field
The utility model relates to a kind of wire-rope flaw detector, a kind of specifically intrinsic safety portable wire-rope flaw detector.
Background technology
Wire rope is widely used in each departments of national economy such as coal, metallurgy, building, water conservancy, tourism, port and pier, communications and transportation as crucial key member in lifting, transportation, lifting and the load bearing equipment.The safe operation of great equipment of the use of wire rope and industry-by-industry and critical facility is closely related.
In order to guarantee the safe operation of wire rope, the scientist of various countries is just carrying out unremitting exploration and research aspect the nondestructive examination of wire rope always.Safe in utilization in order to ensure wire rope, the mode that can only adopt simple manual detection or regularly change rope with the rope unit.Manual detection, the surface damage of observation wire rope that can only be limited, and to the fracture of wire of wire rope inside, wearing and tearing, corrosion especially great disconnected rope hidden danger such as fatigue, then can't discover at all; Regularly change the mode of rope, not only cause the huge waste of wire rope more than at least 1/3 in every year, strengthened production cost, and this mode can not be guaranteed the safe in utilization of wire rope.
At present, worldwide, usually magnetic inspection technique and non-magnetic inspection technique branch are classified as two branches of wire rope nondestructive testing technique.Non-magnetic inspection technique generally is under specific technical conditions, to adopt.Because the flaw detection media formation condition that relates to is harsh, technical sophistication, cost of equipment and cost of use are very high, praise highly so only aspect scholastic attainment, receive for the moment, really do not obtain practical application afterwards, also are in the laboratory study stage so far.The magnetic inspection technique is the most representative is the inductive coil technology of inventing at the beginning of last century and the Hall element technology (being called for short strong magnetic flaw detection) of the last century invention in mid-term, and afterwards the American with the combine technology of use of Hall element and inductive coil.These several kinds of magnetic inspection techniques all are under the state of wire rope a bit being implemented strong magnetic pumping, to accomplish to survey.The high-intensity magnetic field excitation oversaturated wire rope in magnetic field down is in one very among the complex magnetic environment; These magnetic fields had both comprised the magnetic field of wire rope itself and damage thereof; Also include terrestrial magnetic field, electromagnetic field or the like; We call " signal " to the Magnetic Field of all damages in the wire rope, and we then are referred to as " noise " in the detection process other Magnetic Field.In detection, the influence that the flower of being restricted, rope shake, speed and external magnetic field change, detection process follows in a large number " strand ripple " noise to occur with " wild point " (local anomaly signal just).Therefore; The most basic, most important requirement is exactly a signal of under various interference, discerning damage of steel cable delicately, like clockwork to wire rope flaw detection equipment; Get rid of various noise; Thereby obtain the real information of damage of steel cable, and on this basis these information are carried out analyzing and processing, form judgement damage of steel cable.And inductive coil and Hall element technology have geneogenous critical defect in this regard.The sensitivity of the sensor of inductive coil and Hall element is very low: the one, can't capture faint relatively damage signal delicately; The 2nd, can't eliminate the various external worlds " noise " and disturb; The 3rd, result of detection is extremely unstable.These reasons cause these two kinds of detector devices all to be difficult at present obtain real damage of steel cable information just, and based on analysis and judgement on these information bases, and the conclusion that draws thus also just is difficult to convincing.
