Ultrasound detection is a kind of important method of non-destructive testing technology, high, the easy to operate, testing cost with detection accuracy
Low, the fireballing advantage of detection.It is usually used in the automatic detection of material internal quality, as steel plate factory before quality inspection,
Rail quality on-line checking, storage tank are creeped detector etc..To realize automatic ultrasonic detection, ultrasonic probe can be made into wheeled
Detection structure, principle of compositionality be ultrasonic probe be installed on the axis of wheeled construction, wheel skin use a kind of softer solid coupling
Condensation material takes turns interior hydraulically full couplant.When detecting, holding shaft does not rotate, and makes to take turns under the action of certain pressure and thrust
Sub- pivoting and roll be carried forward scanning.Guarantee that the purpose that does not rotate of axis is to maintain ultrasonic probe acoustic beam and is directed toward constant, makes
Ultrasonic energy enters to inject in checking matter and receives reflection echo at an angle always.
It needs to come into full contact with wheel skin with checking matter wheeled construction application certain pressure when detecting, since wheel skin is a kind of
Quality is softer, deformable material, it is also the part in wheeled construction with checking matter mere contact, if rolling scanning
It is uneven along the deformation of force direction wheel skin in the process, then skin is taken turns along scanning direction or so meeting deflection, causes wheel shaft or so deflection, from
And makes ultrasonic probe that left and right deflection occur, influence its normal transmission and receive detection signal.If wheel shaft is sent out during scanning
Raw rotation can make ultrasonic probe along deflection before and after scanning direction, also will affect the transmitting-receiving of detection signal.Therefore, one kind need to be designed
The auxiliary stabilizing mechanism of wheeled supersonic detection device makes it in the detection process and can guarantee that ultrasonic probe is stablized receiving and transmitting signal and made
The ultrasonic probe of deflection is quickly aligned.
Utility model content
According to above-mentioned mentioned wheeled supersonic detection device in the detection process there may be caused by probe deflection not
The problem of stablizing receiving and transmitting signal, the utility model proposes a kind of auxiliary stabilizing mechanisms for wheeled supersonic detection device, so that
Ultrasonic probe can stablize transmitting-receiving detection signal in the detection process.
The utility model adopts the following technical solutions:
A kind of auxiliary stabilizing mechanism of wheeled supersonic detection device, including wheel shaft holding frame, clamping alignment device, support knot
Structure.
The wheel axis clamping of probe wheel is kept fixed it when probe wheel rolls by wheel shaft holding frame, guarantees in probe wheel
Ultrasonic probe be directed toward it is constant.Clamping alignment device is by being threadedly coupled on the wheel shaft for being installed on probe wheel, when wheel shaft and wheel axle clamp
Holding frame loosening causes ultrasonic probe along when deflection, can clamp alignment device by adjusting be such that ultrasonic probe returns to before and after scanning direction
Normal operation position.
Support construction is made of support arm, support wheel, telescopic rod, returning spring.The two sides of probe wheel wheel shaft are respectively articulated with
Two support arms are cased with a reply bullet on telescopic rod bar by the telescopic rod lateral connection of a variable-length between two ipsilateral support arms
The both ends of spring, spring are connected on support arm, and the other end of two support arms is connected by a hinge with two support wheels respectively.Axis two sides
Support wheel again by a fixed length bar connect, form one tool there are four support wheel probe wheel support construction.It is visited when using
When great wheel detects, pressure need to be applied to it, pressure effect lower whorl skin is deformed, and ipsilateral two support arm of support construction occurs opposite
Rotation, telescopic rod elongation, spring are in tensional state, and the spacing between ipsilateral support wheel expands.During taking turns skin deformation, branch
Support structure changes with the deformation of wheel skin, and the left and right sides of support probe wheel, makes to take turns skin deformation uniformly always, guarantees ultrasonic probe
It is unbiased along scanning direction or so, to realize that stablizing for detection signal is received and dispatched, when pressure removes, acted in returning spring
Under, support arm, support wheel and telescopic rod are returned to original position again.
The beneficial effects of the utility model are: the utility model proposes a kind of auxiliary of wheeled supersonic detection device to stablize
Mechanism, it can overcome the problems, such as follows: (1) probe wheel is in the detection process since wheel skin deformation makes ultrasonic probe along a scanning direction left side
Right bank causes ultrasonic signal transmitting-receiving unstable；It (2), can be by adjusting clamping levelling when probe is tilted forward and back along scanning direction
Device makes ultrasonic probe return to normal operation position.As a kind of auxiliary body, probe wheel normal table transmitting-receiving ultrasound can guarantee
Detect signal.
