Abstract
The utility model relates to conducting magnetic material, particularly an automatic detector for detecting the number of the wires which are broken for a steel wire cable and the worn condition of the steel wire at the outer layer. The automatic detector comprises an inductive sensor, a signal conditioning converting circuit, a computer system, a recordation and display system, and an alarm system. The automatic detector can be used for analyzing the number of the wires which are broken for a steel wire cable and the wearing capacity of the steel wire at the outer layer in a quantitative mode. The automatic detector is suitable for the in-line detection for a steel wire cable. When the number of the wires which are broken for a steel wire cable or the wearing capacity of the steel wire at the outer layer reaches the discarded standard, the alarm system controlled by the computer system can give an alarm.
Description
The utility model relates to a kind of magnetic conductive material, especially the automatic tester of steel rope fault and cover wire wearing and tearing.It comprises sensor, Signal Regulation change-over circuit, computer system, input-output system, warning system.
The broken wires of wire rope and cover wire wear extent, be two of wire rope main scrap index.Detect with wire rope and scrap usage range at the GB5972-86(hoisting machinery) in stipulated the detection method of steel rope fault and wearing and tearing, promptly so-called observation method.At " handling machinery ", in 1988 the 12nd phases " the wire rope monitoring of rope-driven conveyor and the adjustment synchronously " literary composition, introduced the leakage magnetic flux method that only is used for Detecting broken wires in steel rope.The leakage magnetic flux method is to utilize magnetizing assembly, makes wire rope magnetization and saturated, by the coil-induced or leakage magnetic flux of magneto sensor detection because of existing fracture of wire to produce in the wire rope, to reach the purpose of detection.Their weak point is, observation method is subjected to the influence of wire rope working environment, and the people is difficult to detect reliably fracture of wire.The leakage magnetic flux method is disguised the living high-intensity magnetic field of buying property owing to exist by permanent magnet or electromagnet equimagnetic, can influence detection signal, and sensitivity is low, and accuracy rate is low.Huge magnetizing assembly more is not suitable for the online detection of wire rope.When there was fracture of wire in inside, because the shielding action of cover wire, interior flux leaked not come out, so can't detect.For the detection of cover wire wear extent, then utilize general measurer by the testing staff, detect the diameter of the xsect of limited several wire rope, judge whether wear extent exceeds standard, obviously, be difficult to detect real critical section like this.The leakage magnetic flux rule can't detect the wearing and tearing of wire rope.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part, and design a kind of high-intensity magnetic field that do not have, no huge magnetizing assembly, can detect the inside and outside fracture of wire of wire rope simultaneously, and wire rope cover wire wear extent, and the online detection of suitable wire rope, sensitive wire rope automatic tester reliably.
The purpose of this utility model can reach by following measure: detector with inductance type transducer as detecting sensor, one section of wire rope seals in the sensor magnetic circuit, iron core passes cell winding and then forms closed magnetic circuit, perhaps the steel wire penetrating cell winding becomes open circuit, when occurring the wearing and tearing of fracture of wire or cover wire in the wire rope, the magnetic resistance that the capital the makes magnetic circuit volume of actual iron core in other words changes, and causes that the inductance of cell winding or mutual inductance change.Utilize common inductance or mutual inductance signal to regulate change-over circuit, make variation conversion or voltage, electric current or the frequency signal of inductance or mutual inductance, sampling of input computer system and data processing, can judge the size of broken wires and wear extent, utilize the exportable result of display or registering instrument, when broken wires or wear extent exceed standard, report to the police by the computer control warning system.
The purpose of this utility model can also reach by following measure: when adopting the open-flux path inductance type transducer, make cell winding inner radius coil width less than 10mm.No matter be open-flux path, or closed magnetic circuit, the size of the working current in the cell winding, in the time of should guaranteeing that wire rope is magnetized, its magnetic permeability is lower than the initial permeability of wire rope, and in addition, computer system adopts microcontroller system.
Compared with prior art, the utlity model has following advantage:
1, do not have high-intensity magnetic field and huge magnetizing assembly, improved the sensitivity and the accuracy rate of instrument, and be fit to online detection.
2, no matter be inner fracture of wire, still outside fracture of wire or wearing and tearing all will make magnetic resistance or core volume change, and cause the variation of inductance or mutual inductance, overcome the defective that prior art can not detect inner fracture of wire.
3, because wire rope is operated in below the initial permeability, make the detector tool stable and repeated preferably.
Press accompanying drawing 1, wire rope 1 passes cell winding 2, the width 3mm of cell winding 2, wire rope 1 becomes the iron core of coil 2, inductance L among the figure, capacitor C constitutes the basic circuit elements of sensor, the pumping signal of oscillator 3 output Frequency and Amplitude Stabilization is added to cell winding 1 via resistance R, and when the inductance L of cell winding 1 changed because of wire rope 1 iron core magnetic resistance changes, the detecting circuit μ of output changed thereupon, after the Mcs-51 microcontroller system carries out sampling processing to μ, the output result.
According to accompanying drawing 2, wire rope 1 constitutes the sensor closed magnetic circuit with iron core 8, and the Signal Regulation change-over circuit is an electric bridge, and the inductance L of cell winding is an arm of electric bridge, other three arms meet Z1, Z2, Z3 respectively, when the magnetic resistance of closed magnetic circuit changed because of the fracture of wire of wire rope or wearing and tearing, inductance L changed thereupon, destroys the original balance of electric bridge, output △ μ, △ μ exports V after filtering, after the Mcs-51 microcontroller system carries out sampling processing to V, and the output result.
