Abstract
The invention relates to a detector of broken wires in a steel rope. The detector consists of a U-shaped magnet, a Hall sensor group, a steel rope to be detected, a detection circuit and an alarming circuit; a circle is defined by the Hall sensor group; the steel rope to be detected passes through a center hole of the Hall sensor group; and a square is defined by the U-shape magnet and a small section of the steel rope to be detected so that the Hall sensor group is located between an N (North) pole and an S (South) pole and the steel rope to be detected can freely move left and right. If a part of the steel rope is broken, the Hall sensor group detects large flux leakage when a crack passes through the Hall sensor group, and the alarming circuit emits light and buzzing after the detection circuit detects the large flux leakage. The detector of the broken wires in the steel rope has the advantages of simple structure, low cost and good operability.
Description
Technical fieldThis invention relates to fields such as electronic technology, sensing technology and machinery.
Technical backgroundWire rope is applied to a plurality of fields such as crane, crane, cable car widely, and wire rope can fracture of wire take place because of fatigue year in year out, exists potential danger.And the normal conditions utilization is artificial wire rope to be detected, but lacks real-time, and this contrive equipment can replace manual work to detect the fracture of wire situation of wire rope in real time.
Summary of the invention
The present invention relates to a kind of Detecting broken wires in steel rope appearance, this device is made up of U type magnet (1), Hall element group (2), wire rope to be measured (3), testing circuit (4) and warning circuit (5); Hall element group (2) surrounds an annular; Wire rope to be measured (3) passes from Hall element group (2) center pit; " mouth " font of a bit of composition of U type magnet (1) and wire rope to be measured (3) makes extremely centre of the N utmost point and S that Hall element group (2) is positioned at U type magnet (1).U type magnet (1), the end of its N utmost point and the S utmost point have the circular hole that size is complementary with wire rope to be measured (3), and wire rope to be measured (3) passes and U type magnet (1) is formed " mouth " font from circular hole, wire rope to be measured (3) can about move freely.Hall element group (2) constitutes an annular by a plurality of linear hall sensors, and the just enough wire rope to be measured (3) of the size of ring can pass, and the N utmost point that Hall element group (2) is positioned at U type magnet (1) and S be the centre extremely, is used to detect the leakage field of wire rope.
If the part steel wire fracture is arranged, when breach passed through the Hall element group, the Hall element group detected bigger leakage field, behind testing circuit, makes the luminous and buzzing of warning circuit.
The usefulness of this device is simple in structure, and cost is low, and operability is good.

Specific embodiments
This device of the present invention is made up of U type magnet (1), Hall element group (2), wire rope to be measured (3), testing circuit (4) and warning circuit (5).Hall element group (2) surrounds an annular, and wire rope to be measured (3) passes from Hall element group (2) center pit; " mouth " font of a bit of composition of U type magnet (1) and wire rope to be measured (3) makes extremely centre of the N utmost point and S that Hall element group (2) is positioned at U type magnet (1).
U type magnet (1), the end of its N utmost point and the S utmost point have the circular hole that size is complementary with wire rope to be measured (3), and wire rope to be measured (3) passes and U type magnet (1) is formed " mouth " font from circular hole, wire rope to be measured (3) can about move freely.Hall element group (2) constitutes an annular by a plurality of linear hall sensors, and the just enough wire rope to be measured (3) of the size of ring can pass, and the N utmost point that Hall element group (2) is positioned at U type magnet (1) and S be the centre extremely, is used to detect the leakage field of wire rope.
In the present embodiment, U type magnet (1) can adopt permanent magnet, also can adopt electromagnet, is shaped as the U type, and the N utmost point of U type magnet and the extreme portion of S have circular hole, and the size and the wire rope to be measured (3) of circle are complementary, and wire rope to be measured just in time can pass from the hole.
In the present embodiment, Hall element group (2) is made up of a plurality of linear hall sensors, and the model of Hall element can adopt S496B, or other type sensor.The quantity of sensor is by the size decision of annulus.The sensitive area of sensor is towards circle ring center.
In the present embodiment, testing circuit (4) is the signal that is used to handle Hall element output, and each Hall element is supporting to have a comparer, the sensitivity that the resistance through adjustment comparer reverse input end can regulating circuit.The shared alarm of all comparers, just often, the Hall element output voltage is lower, the comparer output low level; When steel wire had the minority fracture, breach place leakage field increased, and bigger voltage of Hall element output is relatively exported high level, the luminous and buzzing of alarm.
