Abstract
The utility model discloses a multichannel combination formula ultrasonic transducer, including the shell, be provided with linear arrangement's a plurality of ultrasonic wave receiving channel in the shell, be provided with an ultrasonic emission passageway on one side of the receiving channel, there is the sound insulation piece between ultrasonic emission passageway and the receiving channel. The probe has the advantages of compact structure, low cost, high sensitivity and good stability.
Description
Technical field
The utility model relates to a kind of ultrasonic probe, is a kind of multi-channel assembled ultrasonic probe.
Background technology
Enforcement along with " the provisional technical conditions of 350Km/h Line for Passenger Transportation 60Kg/m rail ", railroad is more and more higher to the requirement of rail product internal soundness, and online UT (Ultrasonic Testing) had higher requirement, made clearly regulation to the web of the rail cross-sectional area of detected rail with reference to artificial defect.It has the flat-bottom hole 2 of 6 φ 2mm with reference to the artificial defect layout as shown in Figure 1 at the web of the rail short transverse interval of rail 1 10mm.Flaw detection requires the area of UT (Ultrasonic Testing) to be greater than 70%.
The general employing along rail of present domestic rail web of the rail UT (Ultrasonic Testing) vertically arranged a plurality of single probes, promptly corresponding each artificial defective locations will have a probe, or adopt wafer to overcharge multiple probe and guarantee the area of detecting a flaw, this method has following shortcoming: 1, arrange a plurality of single probe line flaw detections, a plurality of probes location is inaccurate, and the flaw detection precision is low; 2, adopt wafer to overcharge multiple probe and rail surface surface of contact defective coupling, stability is not strong, and data-signal is prone to interference between a plurality of passages, causing the flaw detection fail to report, report by mistake many, the flaw detection requirement that does not reach standard " the provisional technical conditions of 350Km/h Line for Passenger Transportation 60Kg/m rail "; 3, big to the erecting stage space requirement, the quantity that mechanical hook-up is required is many.Above-mentioned shortcoming can cause the accuracy and the reliability variation of flaw detection.
The utility model content
At the physical dimension and the requirement of 100 meters long chi rail examinations of the 60kg/m rail web of the rail, the purpose of this utility model is to provide a kind of novel multichannel ultrasonic probe, adopts this probe good reliability of detecting a flaw, and can reduce rate of failing to report.
The utility model adopts following technical scheme: multi-channel assembled ultrasonic probe, comprise shell, be provided with linearly aligned a plurality of ultrasound wave receiving cable in the enclosure, be provided with a ultrasonic emitting passage in receiving cable one side, the sound insulation piece is arranged between ultrasonic emitting passage and the receiving cable.
On the sound insulation piece between described ultrasonic emitting passage and the receiving cable, can be compounded with Copper Foil, received signal one utmost point of this Copper Foil and the receiving cable common ground that links together.
According to 60kg/m rail web of the rail flaw detection requirement, described linearly aligned ultrasound wave receiving cable preferred number is 2 to 5, generally can satisfy rail web flaw detection requirement.
The beneficial effects of the utility model are:
(1) transmission channel and a plurality of receiving cable in a probe, have been arranged, a probe test surface can cover the physical dimension of the 60kg/m rail web of the rail and the scope of artificial defect on web of the rail short transverse of 100 meters long chi rail, only need two probes to be staggered and correspond respectively to basic idol worker's defective hole, then can satisfy the flaw detection area of standard-required, for the scene installation stays bigger space, the quantity that mechanical hook-up is required is few, need not stay more line between instrument and the probe, make things convenient for the flaw detection operation.
(2) with respect to single probe, because of the time can reducing by four probes, thereby can make mechanical hook-up compacter and more become rationally in flaw detection, can guarantee that probe contacts well with the rail surface, has improved the stability of detecting a flaw.
(3) adopt multicast channel layout structure, compare, avoided the interference of mutual data-signal, strengthen the consistance of instrument and probe with overcharging multiple probe.Particularly also increased the Copper Foil of ground connection between transmission channel and receiving cable, surplus sensitivity, resolution, signal to noise ratio (S/N ratio) improve relatively.Improve the accuracy and the reliability of result of detection, reduced rate of failing to report, prolonged serviceable life.
(4) adopt the multicast structure, reduced cost, increased benefit.
In a word, adopt this novel multi-channel combination ultrasonic probe can guarantee the flaw detection requirement of high-speed high-quality rail, for running at high speed of train provides strong safety curtain.
Description of drawings
Fig. 1 is a 60kg/m rail web of the rail artificial defect arrangenent diagram.
Fig. 2 is a kind of multi-channel assembled ultrasonic probe floor plan of the present utility model.
Fig. 3 is for adopting multi-channel assembled ultrasonic probe flaw detection mode synoptic diagram shown in Figure 2.
Embodiment
Below in conjunction with accompanying drawing and a preferred embodiment multi-channel assembled ultrasonic probe of the present utility model is described further.
As shown in Figure 2, be arranged with by piezoelectric chip in probing shell 1 internal linear and constitute three ultrasound wave receiving cables 11,12,13, be furnished with a ultrasonic emitting passage 14 that constitutes by piezoelectric chip in three ultrasound wave receiving cables, 11,12,13 1 sides, form one three and receive multi-channel assembled ultrasonic probe.Longer by receiving cable, can adopt three interconnective piezoelectric chips to constitute.Signal disturbs between the hyperchannel in order further to reduce, and has sticked with glue one deck Copper Foil 15 on the sound insulation piece 16 between receiving cable 11,12,13 and the transmission channel 14, and Copper Foil 15 is connected back ground connection with a utmost point of three receiving cables 11,12,13.This one receives multiple multi-channel assembled ultrasonic probe, both had and overcharged the big advantage of multiple probe flaw detection area, structure is compact again and overcome the signal of overcharging multiple passage and disturb, strengthened the consistance of instrument and probe, improved the integrated performance index of instrument and probe, and can reduce cost.
During use as shown in Figure 3, according in the standard with reference to the layout feature of artificial defect, 6 artificial defects 2 are divided into two groups by odevity, and according to the physical dimension characteristics of the web of the rail, two probes 3,4 are staggered, have just guaranteed the flaw detection area that requires in the standard fully.Compare with traditional mode, probe quantity has reduced four, and mechanical hook-up is compacter more to become rationally thereby make, and has improved stability; Higher accuracy and the reliability that has improved result of detection of flaw detection repetition rate reduced rate of failing to report, guaranteed the flaw detection requirement of high-speed high-quality rail.For the high speed driving of train provides strong safety curtain.
