Abstract

The flushing probe for automatic ultrasonic flaw detection is a twin probe matched with ZSF-H type ultrasonic full-automatic steel rail flaw detector, and comprises a shell, triangular cutting blocks and wafers, wherein the twin wafers on the inclined plane of the triangular cutting blocks form two included angles with the normal line, the included angle is 29-31 degrees, a water injection pipe which can be connected with the flaw detector is arranged on a shell cover, a water outlet groove which is communicated with the water injection pipe is arranged on the bottom surface of the shell, wear-resistant grinding blocks are arranged at two ends of the bottom surface of the shell, and lugs arranged on two end surfaces of the shell can be connected with a holder of the flaw detector. The utility model discloses the echo is sensitive, and the SNR is for being more than or equal to 20db, replaces the oil coupling with the bath, and is from the slipperiness good, simple structure, convenient to use, and processing is easy, and is with low costs.

Description

Automatic ultrasonic inspection bath probe

The utility model relates to a kind of automatic ultrasonic inspection bath probe, claims transducer again, is the supporting probe of ZSF-full-automatic rail defectoscope of H ultrasound wave.

Two strands of rail as rolling stock operation basis on the railway line are directly connected to safety of railway transportation.The fatigue damage of generations such as the geneogenous damage of rail or overload use, extended active duty is all answered active prevention, the accurately position that detects wound and the development thereof of unit's mistake as early as possible.The touring flaw detection requires to possess the defect-detecting equipment of altitude maneuver ability in the crack on very long circuit, between train operation, and ultrasonic flaw detection occupies first of the conventional flaw detection, for obtaining correct result of detection reliably, except the capability and performance of instrument itself, depend primarily on the adaptability of probe quality and application.

In the operation of existing rail examination, for probe with visited the lubricated of rail attrition surface, be everlasting rail oil surface or watering, like this, oiling cost height, the limit oiling or while sprinkle water the obvious work efficiency of flaw detection manual operations is very low.Probe wafer incident angle clutter is big.

The purpose of this utility model is to avoid the deficiencies in the prior art part, and provide that a kind of continuous bath, sliding certainly property are good, installation, demolition are convenient, wear-resistant, simple in structure, handling ease, automatic ultrasonic inspection bath that cost is low are popped one's head in.

The purpose of this utility model realizes by following technical proposal.

The acoustic absorbant that coats in the triangle organic glass stripping and slicing that the utility model includes triangle organic glass stripping and slicing that centre in shell, casing cover, the shell is separated with sound insulating layer, two wafer on triangle organic glass stripping and slicing two inclined-planes, lead that the positive and negative two sides of two wafer connects respectively, have wafer and the immobilization material of affixed acoustic absorbant and shell, the two plates on the triangle organic glass stripping and slicing inclined-plane and two angles of normal---incident angle is 29～31.Casing cover is provided with two water injection pipes and two flexible pipes that are installed with lead, the shell bottom surface is provided with two effluent troughs that communicate with two water injection pipes, the abrading block that is connected with shell through screw is equipped with at two ends, shell bottom surface, one lug respectively is housed on the both ends of the surface of shell, is connected with clamper on the automatic inspection equipment.

The utility model compared with prior art has following advantage:

1, two lugs on the shell both ends of the surface, make probe in use on automatic inspection equipment loading, unloading very convenient.

2, the abrading block at two ends, shell bottom surface has wear-resistant, the sliding certainly good advantage of property, improves 7～8 times serviceable life.

3、29～31。The wafer incident angle can get very sensitive echo, signal to noise ratio (S/N ratio) is 〉=20db.Double crystal probe one emission one receives, and is easy to use.

4, the water injection pipe on the casing cover is connected with the water source of automatic inspection equipment, and couplant---water flows to rail by the effluent trough of its bottom surface in use, and flaw detection has been played with the lubricated use of water for oil while washing by water, and greatly reduces use cost.

5, the utility model simple in structure, make handling ease, cost is low, has obvious practicability.

The explanation of accompanying drawing drawing:

Fig. 1 is a upward view of the present utility model.

Fig. 2 is a front elevation of the present utility model.

Fig. 3 is a vertical view of the present utility model.

Fig. 4 is a cut-open view of the present utility model.

Fig. 5 is Fig. 2 side view.

Following the utility model will describe in detail embodiment (in conjunction with the accompanying drawings).

The centre that the utility model shown in Figure 4 includes in shell 1, casing cover 2, the shell 1 is separated with the triangle organic glass stripping and slicing 20 (seeing Fig. 1 and 4) of sound insulating layer 19, two wafer (7 and 8) on 20 liang of inclined-planes of triangle organic glass stripping and slicing, and the lead (21,22,23 and 24) that the positive and negative two sides of two wafer (7 and 8) is connected respectively passes two flexible pipes (15 and 16) respectively and is connected with automatic inspection equipment.

Wafer (7 and 8) on triangle organic glass stripping and slicing 20 inclined-planes and normal two angles---incident angle is 29～31 °.The frequency of wafer (7 and 8) is 5MHZ.

The abrading block (5 and 6) (seeing Fig. 2,4 and 5) that is connected with shell 1 through screw (17 and 18) is equipped with at two ends, shell 1 bottom surface.Lug (3 and 4) is housed respectively on the both ends of the surface of shell 1, is contained in during use on the clamper of automatic inspection equipment.

During flaw detection, earlier lug of the present utility model (3 and 4) is contained on the automatic inspection equipment clamper, water injection pipe (13 and 14) is connected with automatic inspection equipment with lead on the positive and negative two sides of wafer (7 and 8).To pop one's head in and survey, simultaneously couplant along the rail waist---on rail, the defect reflection in the rail shows on the screen to automatic inspection equipment water along shell effluent trough (11 and 12) stream.The signal to noise ratio (S/N ratio) of probe is 〉=20db that sensitivity is 〉=52db.
