Puccinia graminis eating off filament test system, it is strong operability, safe and reliable, easy to operate.
To achieve the above object, the utility model is adopted the following technical scheme that：
A kind of bridge cable puccinia graminis eating off filament test system of multi-parameter regulation, it includes tensioning geosyncline, the tensioning geosyncline
Provided with multiple bayonet socket bearings, a pair of stretch-drawing beams are removably mounted on any two bayonet socket bearing, and the system also includes connection
Fixed dress is retouched in anchor, magnetostriction guided wave detector, stretch-draw jack for catching rope bar corrosion signal, the connection
Put including fixing end anchorage, adapter sleeve, pull bar, heel brace and the pull-rod nut for anchoringwire bar, rope bar is by adapter sleeve with drawing
Bar is connected, and the pull bar is anchored on moveable anchor after passing through stretch-drawing beam pull-rod nut, heel brace and stretch-draw jack.
Preferably, the tensioning geosyncline is the oblong openings casing for being depressed in underground, and the bayonet socket bearing is to be located at length
A pair of lug bosses of square aperture casing both sides.
Preferably, the bayonet socket bearing on tensioning geosyncline is arranged at equal intervals.
Preferably, the signal driving source and signal that the magnetostriction guided wave detector includes being arranged on rope bar are received
Device, the signal analysis device being electrically connected with the driving source and receiver.
Preferably, the stretch-drawing beam is provided with arcuate recess.
Preferably, the middle part of the stretch-drawing beam is angular in rounding.
Compared with prior art, the beneficial effects of the utility model are：
The utility model can adjust the active length of rope bar by adjusting the position of stretch-drawing beam, very heavy by controlling
Push up tensioning and draw pull-rod nut anchoring, rope bar can be adjusted and be in different stresses, by corroding to rope bar steel wire
Property processing or cut, can adjust rope bar steel corrosion destructiveness and position, pass through quantitative regulation rope bar destructiveness and position, magnetic
The signal under flexible Guided waves instrument detection current state is caused, so that analytical derivation detection signal is corresponding with rope bar corrosion condition
Relation and determination methods, it is established that the test that Suo Li, length and extent of corrosion can adjust and calibrate, it is simple in construction.
