Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model ultrasonic wheel type probe;
Fig. 2 is the axial cross-sectional views of ultrasonic wheel type probe shown in Fig. 1.
Embodiment
As shown in Figure 1, the utility model ultrasonic wheel type probe mainly comprises: probe foreign steamer 1, some independently ultrasonic probe modules 13,15,16, and water sealing box 2, installs the probe bracket 3 of probe module, couplant 18 etc.Probe bracket 3 is alloy aluminum support, also can be made up of other materials, and the end face of support 3 is surface level.For weight reduction, when intensity allows, a part can be excavated by the middle of plane.The bottom surface of support 3 has multiple probe module installed surface, and installed surface is the inclined-plane becoming predetermined angular with surface level.Certainly, also installed surface can be made surface level, and change control angle by probe.Fig. 1 comprises two makes that ultrasound wave enters the installation inclined-plane of rail with 61 ° ~ 70 ° refraction angles, two installation inclined-planes making ultrasound wave enter rail with 36 ° ~ 47 ° refraction angles make the vertical surface level entering 0 ° of probe of rail of ultrasound wave with one.According to the difference of probe shape and size, installed surface can make corresponding shape and size, preferred the present embodiment is the installed surface of 70 ° of probe modules 15 and 37 ° of probe modules 16 is rectangle, rectangle corner is left screw and is used for fixing probe module, rectangular planes is reserved the installation site of circular hole as 0 ° of probe module 13 at straight-through support 3 top, opening part stays probe positioning table, and support 3 end face arranges positioning screw hole in circular hole both sides.
As shown in Figure 2, probe bracket 3 is fixed silk 8 side with axle and is passed through bobbin 11 by locating shaft 7, side and be connected with inspection car.Locating shaft 7 axle head is semi-cylindrical, semi-circle plane is vertical with 0 ° of probe module acoustic beam, also a fixed angle can be adopted, by adjustment locating shaft semi-circle plane horizontal sextant angle, ensure that probe module injects the accurate of the refraction angle of the ultrasonic acoustic beam of rail, and be provided with axle pilot hole 6, for the connection location between supersonic detecting vehicle with fixing.Go out bobbin 11 for quill shaft, have probe bus and portal 12, be used for drawing probe bus.
As shown in Figure 1, probe module 13,15,16 is contained in the bottom surface of probe bracket 3, probe bracket 3 has the probe lead wire hole 14 leading to top water sealing box cavity 20.The surface of emission of probe is towards couplant 18.Water sealing box 2 is established in the top of probe bracket 3; water sealing box 2 is preferably semi-cylindrical; among the notch being loaded on probe bracket 3 end face; cradle top surface is fixed on by screw 17; and forming closed cavity 20 with support 3, cavity 20, for encapsulating the coupling arrangement of each probe module line and wheel seach unit bus, makes it to keep apart with coupling liquid; protection probe line, probe bus to be portalled 12 extractions by going out bobbin 11 bus.Probe module is prefabricated wheel seach unit dedicated probe, and each is independently, only need open water sealing box 2 during replacing, dismounting convenience easy to maintenance.
As shown in Figure 2, at locating shaft 7 with go out on bobbin 11 to add shaft seal 4, ring flange 10, bearing 5 successively, probe foreign steamer 1 is enclosed within two ring flanges 10, then silk 19 is fixed together with ring flange 10 compact siro spinning technology by foreign steamer pressure ring 9 foreign steamer pressure ring, form confined space, fill couplant 18 in confined space, probe module 13,15,16, support 3 and water sealing box 2 be immersed in couplant 18.Drive ring flange 10, shaft seal 4, bearing 5 to rotate together when rolling on rail when popping one's head in, and axle is fixed, the probe bracket 3 be spirally connected with it accordingly is also fixed, ensure that the probe surface of emission is always downward towards rail.Shaft seal 4 is rubber, and it and support shaft closely cooperate, the spilling of inner couplings medium when preventing bearing 5 from rotating, and same ring flange 10 excircle uses thread Pilot hole, is also the spilling preventing couplant.Ring flange 10 is arranged a water injection hole and a vent port, be used for pouring into couplant 18 in probe, the present embodiment selects water as couplant 18, according to the difference of environment for use condition, other liquid also can be selected to make couplant.
Probe foreign steamer 1 is circular, directly contacts with rail, so entrant sound should be selected to get well and have the material of sufficient intensity and toughness to make during flaw detection.The probe surface of emission is to couplant 18, and ultrasound wave enters rail through couplant 18 just can complete flaw detection task.According to hyperacoustic propagation characteristic, when in ultrasound wave oblique incidence to heterogeneous interface, by generation reflection and refraction, needed for flaw detection is the wave beam being refracted into rail, by acoustics refraction principle sin α/sin β=c
1/ c
2(wherein α is incident angle, β is refraction angle, c
1, c
2for the velocity of propagation of sound wave in two media) known, couplant one timing, only need determine that sound wave enters the angle of rail, just can know the incident angle of sound wave, namely on support 3, probe installs the angle of inclined-plane and surface level.According to the flaw detection demand of rail, preferred support 3 being installed bevel angle is 16 ° ~ 20 ° and 24 ° ~ 26 °.
When inspection car advances, drive probe foreign steamer 1 to roll on rail, the ultrasonic delivery rail that probe is launched, completes flaw detection work through a series of process.
