Become impact.Although intensity, amount of deflection and the wearability of elevator dragging wire rope is required higher, but due to various stress effects, with
Time also affected by factors such as friction, corrosion, elevator dragging wire rope is easily generated the phenomenons such as fracture of wire, abrasion and corrosion, steel wire
The quality of rope form condition directly affects the safety of elevator and passenger.
For a long time, in order to improve service life and the elevator safety coefficient of elevator dragging wire rope, repair and maintenance personnel can be through
Often elevator is carried out regular repair and maintenance inspection work.But owing to the detection of elevator dragging wire rope be there is no the instruments of inspection of science
Limit so that typically can only estimate, or detect accordingly by the method for vernier caliper measurement, thus make its testing result accurate
Exactness and degree of accuracy are poor, often cause steel wire rope to exceed the time limit to use or change in advance, have both affected the safe handling of elevator, made again
Great cost is become to waste.
The system being applied to defect in rope detection at present exists that volume is big, cost is high, precision is low, poor reliability etc. lacks
Point.
Summary of the invention
In order to overcome the shortcoming of upper described prior art, this utility model provides a kind of elevator dragging wire rope defect inspection
Examining system, is acquired elevator dragging wire rope flaw indication efficiently and analyzes, thus uses elevator dragging wire rope
Safety is estimated.
This utility model realizes with following technical scheme: a kind of elevator dragging wire rope defect detecting system, including
Two set detection devices；Often set detection device includes for steel wire rope carrying out magnetized magnetizing assembly and for gathering leakage field letter
Number signal pickup assembly；Described signal pickup assembly uses multiple Hall elements, and multiple Hall elements are according to matrix
Arrangement constitutes a circle detection circle, and described magnetizing assembly includes two excitation mechanisms, the setting that two excitation mechanisms are symmetrical
Both sides at circle detection circle；The circle detection circle of machine room steel wire rope the most a set of detection device passes, sedan-chair top steel wire rope
Pass from the circle detection circle of other set detection device；The signal of collection is sent out by the circle detection circle in two set detection devices
Deliver to processor；Processor is wirelessly transmitted to monitor supervision platform by after the signal processing of reception.
Preferably, described excitation mechanism is by soft magnetic bodies, and the permanent magnet being arranged on soft magnetic bodies two ends is constituted, and two forever

Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is this utility model theory diagram.
In figure: 1, excitation mechanism, 11, permanent magnet, 12, soft magnetic bodies, 2, Hall element.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of elevator dragging wire rope defect detecting system, including two set detection devices；Often overlap inspection
Survey device to include for steel wire rope carrying out magnetized magnetizing assembly and for gathering the signal pickup assembly of magnetic leakage signal；Institute
The signal pickup assembly stated uses multiple Hall elements 2, and multiple Hall elements 2 constitute a circular inspection according to matrix arrangement
Surveying circle, described magnetizing assembly includes two excitation mechanisms 1, and what two excitation mechanisms were symmetrical is arranged on the two of circle detection circle
Side；Passing in the circle detection circle of machine room steel wire rope the most a set of detection device, sedan-chair top steel wire rope is from other set detection dress
The circle detection circle put passes；The signal gathered is sent to processor by the circle detection circle in two set detection devices；Process
Device sends after the signal processing of reception to monitor supervision platform.
Excitation mechanism 1 is by soft magnetic bodies 12, and the permanent magnet 11 being arranged on soft magnetic bodies two ends is constituted, two permanent magnet correspondences
N pole and S pole for permanent magnet.Permanent magnet is for magnetizing steel wire rope, and soft magnetic bodies is mainly used in changing the direction of the magnetic line of force,
The magnetic resistance making whole magnetic loop minimizes.
Hall element uses high-precision linear Hall element, and high-precision linear Hall element carries out matrix arrangement group
Become, establish spatial triaxial Measurement Method for Magnetic Field, it can be deduced that the stray field at steel rope fault is in axial, radial direction and circumference point
The vector correlation of cloth.
In the present embodiment, processor uses DSP signal processor
Operator only need to penetrate detecting system steel wire rope can complete the collection to defect in rope signal and process,
Available software analysis goes out steel rope fault situation, and operation principle is as in figure 2 it is shown, whole detection analysis process includes measuring object
The signal that Hall element is collected by the i.e. magnetization of steel wire rope, the signals collecting of Hall element, DSP signal processor is carried out
The signal that process, DSP signal processor processes are crossed is wirelessly transmitted to monitor supervision platform and is analyzed.
Work process: steel wire rope passes from position shown in Fig. 1, when steel wire rope generation fracture of wire, the magnetic signal at fracture of wire
There is clear signal；Magnetic leakage signal at this is exported to DSP signal processor processes, DSP signal processor by Hall element
Signal after processing is wirelessly transmitted to monitor supervision platform, and data are analyzed processing by monitor supervision platform, thus use steel wire rope
Safety is estimated.
