Description
Technical field
The present invention relates to a kind of defectoscope of wire rope, particularly a kind of elevator dragging wire rope high speed defectoscope sensor with quarter-phase magneto sensor, it belongs to the technical field of nondestructive testing of Safety Supervision on Special Equipment and elevator installation repair and maintenance industry.
Background technology
1906, First wire rope electromagnetic nondestructive instrument was in the world invented in South Africa, and over more than 100 year, the stuctures and properties of instrument improves constantly, but ultimate principle is used till today always, and was all made up of sensor and the large critical piece of processor two.
The basic system of sensor and principle of work be as shown in Figure 1: the permanent-magnet steel up and down 1 in sensor is connected by armature 2, and form flux loop, its trend is: N pole-armature-S pole-steel wire-N pole.
When wire rope 10 is by sensor, wire rope 10 is made to magnetize and reach capacity.
When wire rope 10 inside and outside fracture of wire, corrosion, wearing and tearing, loose stock occurs, jumps the signal of leakage field that the defect such as silk, distortion, material change will produce and magnetic flux change, often to change the line of production raw 100 trigger action and the wire rope position signalling that provides in conjunction with scrambler 5, by gathering magnetic induction signal by the poly-magnetic sheet (ring) 3 being positioned at sensor central authorities two magnetoconductivities larger, and being inserted in two poly-magnetic sheet centers, the arrangement magneto sensor (Hall element) 4 being looped around wire rope surrounding receives and exports.
Now, along with the fast development of domestic and international elevator industry, the quantity of elevator increases sharply, thus the accident of wire cable rupture also repeatedly occurs, and needs badly and carries out periodic detection to elevator dragging wire rope, and the defectoscope of elevator dragging wire rope meets the tendency development thus.
When using prior art to detect elevator dragging wire rope, because every platform elevator has the traction steel-cable of 4 ~ 8 dense arrangement, so elevator high and low's circular flow back and forth can only be allowed when detecting, individually each root traction steel-cable is detected, and detection speed is lower than 2m/s, much consuming time, efficiency is very low.
Also someone applies above-mentioned technical method, sensor is expanded to two-layer up and down, many Gen Milie wire rope can be contained, gather the data of whole wire rope simultaneously, but occur on any steel cable once but cannot differentiate after measuring defective data, can only again go to recheck with single wire rope defectoscope, the time spent thus be more, and efficiency is lower.
In addition, elevator dragging wire rope diameter range is from Φ 8mm to Φ 20mm, and the string diameter of wire rope the most carefully only has 0.4mm, in order to ensure the accuracy detected, need the sensor configuring multiple different size, even adopt multiloop elevator dragging wire rope defectoscope, there is this problem too.
If improved above-mentioned prior art, just optionally a set of existing single wire rope defectoscope expansion amplified, consequently cannot distinguish defect is occur on which root wire rope; Or combine overlapping existing single wire rope defectoscope simply, consequently the detection signal of adjacent wires rope disturbs mutually more; Or will overlap existing single wire rope defectoscope sensor step arrangement curtly, its result sensor is too heavy more, be also difficult to use.
Summary of the invention
Technical matters to be solved by this invention overcomes defect existing in above-mentioned prior art, a kind of elevator dragging wire rope high speed defectoscope sensor with quarter-phase magneto sensor is provided, different-diameter can be tackled, the elevator dragging wire rope of many Gen Milie carries out synchronous high-speed detection.
Present invention employs following technical proposal and solve its technical matters: a kind of elevator dragging wire rope high speed defectoscope sensor with quarter-phase magneto sensor, comprise a housing, this housing is by top board, front and back, left side plate and base plate are fixedly connected with rear formation, described cover top plate is fixedly connected with one handle, one end of this handle is rotationally connected a rocking arm, this rocking arm is rotationally connected the scrambler of a coding ranging, one armature is fixedly connected on the inner side of cover top plate, permanent-magnet steel is fixedly equipped with in the space formed inside this armature and base plate, it is characterized in that: in the middle of base plate, be equipped with the track combination that simultaneously can detect at least two wire rope, the central authorities of every block guide rail are equipped with a counterbore from top to bottom, magneto sensor is fixedly put in the middle of this counterbore, described poly-magnetic sheet along tested wire rope radial array on the guide rail of magneto sensor both sides.
The present invention adopts monolateral hard magnetization to many wire rope, synchronous by shape of a saddle composite guideway, inlay two panels ingot iron in the guide rail of every root wire rope both sides and gather magnetic sheet, between sheet, magneto sensor is installed, make reception and the magneto sensor of output detections signal is quarter-phase permutation and combination, namely magneto sensor can gather the detection signal of left and right two wire rope simultaneously, improves anti-interference, and greatly improves Detection results.
