Description
Technical field
The utility model relates to a kind of sensor, particularly relates to a kind of sensor for Weaving Steel Wires damage check.
Background technology
Wire rope as promote, transport and load bearing equipment in critical component be widely used in many engineering fields this, its safety in utilization is most important.The rope strand of wire rope complexity connects stock and severe working environment makes it in use be easy to occur wearing and tearing, corrosion, fatigue, fracture of wire equivalent damage, causes its intensity to decline, causes potential safety hazard.The object of wire rope Non-Destructive Testing is the safe operation ensureing wire rope, and under the prerequisite of safe operation, reduce the waste produced because of premature failure as far as possible.
Power transmission engineering in electric system is used for hanging the wire rope of electric wire, and its cross section is not circular but squarish, because it have employed a kind of special mode, as braiding, is therefore called Weaving Steel Wires.This steel wire rope sling, just like traceless advantage after flexible, distortion, is very applicable to traction.The working environment very severe of Weaving Steel Wires, and require the intensity with high reliability, this just needs repairing and detection.Because of the structure that it is special, existing its Detection results of detection technique is not ideal enough.
Utility model content
The purpose of this utility model is the above problem overcoming prior art existence, provides a kind of sensor for Weaving Steel Wires damage check, effectively realizes the on-line checkingi of Weaving Steel Wires fracture of wire.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of sensor for Weaving Steel Wires damage check, comprise the support be made up of insulated nylon, the surface of described support is covered by the iron yoke with magnetic conduction ability, outer cover is provided with metal shell, described support is positioned at shaft centre line place and is provided with the through hole that wire rope moves, be wound with field coil in the middle part of axle, the end being positioned at field coil both sides is wound with magnetic test coil, is positioned at the set collar on through hole center line when the two ends of described through hole are welded with for ensureing that wire rope moves all the time.
Further, the coil ratio of described field coil and magnetic test coil is 1:1.
The beneficial effects of the utility model are:
The utility model, according to reluctance principle, utilizes the linear incentive on the former limit of differential transformer and the reversal connection of secondary two windings, achieves the on-line checkingi of Weaving Steel Wires fracture of wire, ensure that the safe operation of Weaving Steel Wires.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, and form a application's part, schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is fundamental diagram of the present utility model;
Number in the figure illustrates: 1-support, 11-through hole, 2-metal shell, 3-field coil, 4-magnetic test coil, 5-set collar, 6-wire rope.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
As shown in Figure 1, a kind of sensor for Weaving Steel Wires damage check, comprise the support 1 be made up of insulated nylon, the surface of described support 1 is covered by the iron yoke with magnetic conduction ability, outer cover is provided with metal shell 2, described support 1 is positioned at shaft centre line place and is provided with the through hole 11 that wire rope 6 moves, field coil 3 is wound with in the middle part of axle, the end being positioned at field coil 3 both sides is wound with magnetic test coil 4, is positioned at the set collar 5 on through hole 11 center line when the two ends of described through hole 11 are welded with for ensureing that wire rope 6 moves all the time.
Further, above-mentioned field coil 3 is 1:1 with the coil ratio of magnetic test coil 4.
The principle of work of the present embodiment is as follows:
As shown in Figure 2, wire rope is used as armature by the utility model, if just like the damage of fracture of wire in wire rope, magnetic resistance will change, and moves wire rope along axis, can make the induction electromotive force that two secondary winding change, output voltage; Magnetic resistance change rate is changed by the air cleft gap in armature and common transformer between iron to cause, the change of this representative damage wire rope; When the armature position of common differential transformer changes, the mutual inductance of secondary winding
,
can change; When detecting for steel wire,
,
determined by magnetic resistance, the feature of its signal is differential.Because the diameter of Weaving Steel Wires is mostly less than 30mm, single loop excitation can meet the demands.
