Embodiment
Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.
As shown in Figures 1 to 8, a kind of ultrasound wave on-line checkingi defect-detecting equipment for drill pipe thickening district and friction welding seam, comprise the base 1 set gradually from bottom to up, hoistable platform 2 and mobile probe erecting frame, described hoistable platform 2 is connected with base 1 by elevating mechanism, described mobile probe erecting frame comprises mobile probe stand plate 3, move left plate 8, move right plate 9, left probe holder mounting disc 10 and right probe holder mounting disc 11, mobile probe stand plate 3 is arranged on hoistable platform 2 by ball screw framework 4, driven by movable motor 5 and move forward and backward along hoistable platform 2 axis, on mobile probe stand plate 3, symmetrical installation is left, right slide rail 6, 7, left, right slide rail 6, on 7, correspondence is slidably matched and moves left plate 8, move right plate 9, a described left side, move right plate 8, 9 realize along left by air cylinder driven respectively, right slide rail 6, the movement of 7.Moving left the left probe holder mounting disc 10 of corresponding installation and right probe holder mounting disc 11 on plate 8 and the plate 9 that moves right, left and right probe holder mounting disc 10,11 is semi-circular shape, form circular when left and right probe holder mounting disc 10,11 closes completely in together, corresponding installation ultrasonic probe 16 in left and right probe holder mounting disc 10,11.
Above-mentioned elevating mechanism comprises lifting motor 12, worm and gear lifter 13, lifting guide pillar 14 and lifting guide pin bushing 15, lifting motor 12 is fixed on base 1 end face, the output shaft of lifting motor 12 connects worm and gear lifter 13 by shaft coupling, hoistable platform 2 is connected with base 1 by worm and gear lifter 12, correspondingly on hoistable platform 2 and base 1 installs lifting guide pillar 14 and lifting guide pin bushing 15.Operationally, drive worm and gear lifter 13 to realize moving up and down of hoistable platform 2 by lifting motor 12, lifting guide pillar 14 and lifting guide pin bushing 15 ensure the degree of accuracy moved up and down.
Left and right probe holder mounting disc 10,11 installs ultrasonic probe 16 by probe holder 17.This probe holder comprises the base plate 17-1 be fixed in left and right probe holder mounting disc 10,11, radially slide along annulus and be arranged on the probe mounting box 17-2 on base plate 17-1 and the telescopic cylinder 17-3 for driving probe mounting box 17-2 movable, ultrasonic probe 16 floats and is arranged on probe mounting box 17-2.
At circumferentially uniform 6 probes 16 of the annulus that left and right probe holder mounting disc 10,11 is formed, and wherein 3 probes 16 are positioned at annulus front, and other 3 are positioned at the annulus back side.
In 3, the front probe 16 of the annulus that described left and right probe holder mounting disc 10,11 is formed, 2 is single crystal probe, and 1 is double crystal probe; In 3 probes 16 at the annulus back side, 2 is single crystal probe, and 1 is double crystal probe.Single crystal probe is responsive to the inside and outside wall position of drilling rod, and double crystal probe is responsive to drill pipe body centre, and the integrated use of two kinds of probes, achieves and detect all standing of drill pipe body.
Fall into this failure detector to prevent dust impurity and cause fault, be provided with dust cover 18 in base 1 and hoistable platform 2 outside, left and right probe holder mounting disc 10,11 is outer arranges dust cover 18 respectively.In addition clamp block 19 is set in seat board 3 side, convenient arrangement folding and unfolding electric wire, cable.
In use, can, according to practical condition and drilling rod regulation, elevating mechanism be utilized to regulate the height of this failure detector.The left and right probe holder mounting disc 10,11 of semi-circular shape can move left and right, thus the carrying out flaw detection of the drilling rod that can realize different tube diameters and other tubing, and empty mistake can being realized when not needing carrying out flaw detection, facilitating the material of large gauge (as bored ship) to pass through.Possess single crystal probe and double crystal probe simultaneously, the sensitivity of the defect of single crystal probe detection drilling rod inwall, outer wall is higher, the sensitivity of the defect of double crystal probe detection drilling rod zone line is higher, therefore this failure detector is more comprehensive to the ultrasonic listening of the tubing such as drilling rod, mainly solves the detection that drilling rod specifies male and female button thickened area (300-500mm) in regional extent, friction welding seam (bonding wire ± 40mm region) surface and internal ultrasonic ripple 100%.During on-line checkingi, the ultrasonic probe 16 of the annulus front-back that left and right probe holder mounting disc 10,11 is formed can detect two ends, drilling rod left and right respectively.
Embodiment two
