Description
Technical field
The utility model relates to rail's end portion ultrasound wave test technique automatic, refers to a kind of adjustable ultrasound examination probe cassette particularly.
Background technology
In steel production enterprise, heavy rail will carry out the UT (Ultrasonic Testing) inspection to rail head of rail before dispatching from the factory.Ultrasound wave is the communication process of mechanical vibration in elastic medium of ultrasonic frequency; UT (Ultrasonic Testing) is exactly to utilize the influence of the acoustic properties of material master body and inherent vice to ultrasonic propagation, and size, shape and the distribution situation of non-destruction ground detecting material inherent vice are because UT (Ultrasonic Testing) has highly sensitive; Penetration power is strong; Detection speed is fast, and low cost and other advantages has become one of main method of Non-Destructive Testing.Heavy rail by continuous casting steel billet through heating, multi-set of rolling mill is rolling forms, the steel interior tissue is thin and evenly, very help ultrasonic propagation.Ultrasound wave through emission, lotus root closes and reaches interior, produces reflection echo when meeting defect interface and workpiece bottom, operating personnel read defective locations from oscillogram and compare with the wave amplitude size and with reference value, declare also record at any time of inherent vice situation.Heavy rail molten steel smelt with subsequently rolling processing in may produce be mingled with, defectives such as white point and bubble, all can test through defect detection on ultrasonic basis.
The state-of-the-art technology of the current online high-speed automated detection of heavy rail is the heavy rail Non-Destructive Testing line that Canadian NDT company produces; But practice is found its heavy rail head detection probe cassette and in design, is had certain drawback: during the detection probe sensitivity of calibration rail's end portion both sides; The height that can only rely on the adjustment rail head to detect undercarriage is adjusted the height and position of probe; As long as in the probe cassette 2 probes have any 1 to aim at corresponding people's industrial injury on the appearance rail, 1 probe has in addition just been aimed at people's industrial injury that it is corresponding.Find that through production operation this perfect condition is difficult to reach.According to the requirement of iron mark; Two people's industrial injuries of appearance rail head portion side are respectively apart from rail's end portion tread 14mm and 30mm; The gap and the wearing clearance of probe holder assembly self be 8 degree angles with rail side test surface, owing to can't guarantee that probe cassette is in the abswolute level state.The conveyor roller degree of wear is also different, can't guarantee that a kind rail is in horizontality.Therefore, this sensitivity correction method can not guarantee that 2 probes in the probe cassette simultaneously aim at appearance rail people's industrial injury and obtain best reflection echo with best angle in the optimum height position respectively.The flaw detection sensitivity of proofreading and correct in this state is higher, causes rail's end portion to detect regular wrong report, erroneous judgement.
Summary of the invention
The purpose of the utility model is exactly that a kind of adjustable ultrasound examination probe cassette that detects accurately, can significantly reduce the wrong report phenomenon will be provided.
For realizing above-mentioned purpose; The adjustable ultrasound examination probe cassette that the utility model designed; Comprise the probe box body, said probe box body is provided with static probe frame and movable probe frame, is separately installed with static probe and movable probe in said static probe frame and the movable probe frame.The left and right sides coaxial arrangement of said movable probe frame has the positioning of rotating axle, and the positioning of rotating axle in said left side is installed in the axis hole on the probe box body, and the positioning of rotating axle on said right side is installed in the open pore of fixed angle card.Be provided for tightening up the angle clamping screw of open pore on the said fixed angle card, the two ends of said fixed angle card are connected with the probe box body through the bolt that passes its bolt hole.
As preferred version, the positioning of rotating axle in said left side through axle fixedly slide block be movably arranged in the axis hole of probe on the box body, said axis hole is vertical mounting hole.Said probe box body up and down two ends interts and is provided with the height control bolt that matches with spool fixing slide block.Accordingly, the bolt hole at said fixed angle card two ends also is vertical mounting hole.Like this, can adjust the height of left side and right side positioning of rotating axle synchronously.
Further, the two ends up and down of said movable probe frame are provided with the probe set bolt, and said movable probe is installed in the movable probe frame through the probe set bolt.
The action principle of the utility model is following: when detecting rail head of rail; Earlier the static probe in the probe cassette is aimed at corresponding people's industrial injury on the appearance rail; Then through adjustment movable probe frame; Make movable probe aim at corresponding people's industrial injury on kind rail with best angle, thereby obtain best reflection echo in the optimum height position.
The advantage of the utility model is: in the adjustable ultrasound examination probe cassette that is designed, movable probe can be adjusted detection angles separately, can also adjust height up and down.Like this, movable probe matches with static probe, and the detection sensitivity of proofreading and correct out is very accurate, greatly reduces rate of false alarm.Actual detected shows: in rail's end portion both sides ultrasound examination process, the utility model result of use is good.Through adding up: the detection sensitivity debug time of each probe is more than 10 minutes before improving, and shortens to after the improvement about 5 minutes, and operating rate has improved about one times.Rail's end portion detects the erroneous judgement index and reduces to 0.01/1000th from 0.3/1000th, has significantly reduced wrong report, False Rate, greatly improves the lumber recovery of rail.
