Background technology
Ultrasonic test equipment is widely used in multiple technical field, the principle of UT (Ultrasonic Testing) is: when ultrasound wave is propagated in detected material, the change damaging material acoustics characteristic and the interior tissue caused due to material internal can produce certain impact to hyperacoustic propagation, by the detection to ultrasound wave degree of susceptibility and situation, Knowing material performance and structure change.
In the process that the railway system is detected rail, ultrasound wave also can be utilized to detect railway track, damage (as the crackle) situation in detection rail, to take measures to prevent trouble before it happens before rail fracture.
In existing rail defect-detecting equipment, usual use ultrasonic wheel type probe is arranged on inspection car, ultrasonic wheel type probe inside is provided with probe, along with inspection car is in the motion of track, by the probe installed in ultrasonic wheel type probe, be ultrasound wave by electroporation, to import into after track through medium from each group of ultrasound wave launched of popping one's head in and reflect, refraction angle refers to the angle of refracted beam and vertical direction, detects the degree of impairment of rail predetermined position by refracting ultrasound ripple at a predetermined angle.In order to omnibearing detection track, be usually provided with and organize probe more.
No. 201520115122.5 patent discloses a kind of ultrasonic wheel type probe, comprise some independently ultrasonic probe modules, the probe bracket of probe module is installed, couplant, probe bracket by locating shaft with go out bobbin and be connected with inspection car, going out bobbin is have the quill shaft that portals of probe bus, probe module is located at the below of probe bracket, the water sealing box with closed cavity is established in the top of probe bracket, probe line is packaged in closed cavity, and to be portalled extraction by bus, locating shaft and go out bobbin and be provided with bearing, seal, ring flange, probe foreign steamer connects and composes confined space by foreign steamer pressure ring and ring flange, couplant is filled in confined space, probe module, support and water sealing box are immersed in couplant.
In ultrasonic wheel type probe, probe cable line will be released from the axle of hollow, but be filled with couplant in the confined space of wheel seach unit, in order to ensure that medium can not spill, normally at probe line with go out embedding fluid sealant in the middle of bobbin, but such structure is torn open very inconvenient, because fluid sealant is once solidify, just can not take apart, therefore, existing hermetically-sealed construction causes probe replacing to bother very much.
Utility model content
One of technical problem to be solved in the utility model is to provide a kind of good sealing effect and removes and installs simple ultrasonic wheel type probe packoff.
Two of technical problem to be solved in the utility model is to provide the ultrasonic wheel type probe using above-mentioned ultrasonic wheel type probe packoff.
The utility model one of solves the problems of the technologies described above by the following technical solutions: a kind of ultrasonic wheel type probe packoff, comprise bobbin, also comprise O-ring seal, O-ring seal is tightly sandwiched in out in bobbin, it offer some for the hole through probe cable line, the external diameter of the little probe cable line passed in the inner of the internal diameter in hole, the internal diameter going out bobbin is less than the diameter of O-ring seal.
As the technical scheme optimized, described O-ring seal outline is circular.
As the technical scheme optimized, described O-ring seal is elastic seal ring.
The utility model solve the problems of the technologies described above by the following technical solutions two: a kind of ultrasonic wheel type probe, comprise couplant container, probe bracket, some independently ultrasonic probe modules, couplant, couplant is filled in couplant container, probe bracket and probe module are arranged in couplant container, be immersed in couplant, probe bracket by locating shaft with go out bobbin and be connected with inspection car, going out bobbin is have the quill shaft that probe cable line portals, probe module is fixedly located on probe bracket, locating shaft and go out bobbin and couplant container junction is respectively equipped with flange, described ultrasonic wheel type probe also comprises an O-ring seal, O-ring seal is tightly sandwiched in out in bobbin, it offer some for the hole through probe cable line, the external diameter of the little probe cable line passed in the inner of the internal diameter in hole, the internal diameter going out bobbin is less than the diameter of O-ring seal.
As the technical scheme optimized, described O-ring seal outline is circular.
As the technical scheme optimized, described O-ring seal is elastic seal ring.
The utility model has the advantage of: good sealing effect, and remove and install simple, when the probe visited in wheel will be changed, as long as O-ring seal is taken out from the axle visiting wheel, extract out in the hole of the total O-ring seal of line of probe, i.e. replaceable probe, probe is changed very easy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model ultrasonic wheel type probe.
Fig. 2 is the planimetric map of O-ring seal.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Refer to shown in Fig. 1, ultrasonic wheel type probe comprises couplant container 4, probe bracket 3, some independently ultrasonic probe modules 5, couplant 42, couplant 42 is filled in couplant container 4, probe bracket 3 and probe module 5 are arranged in couplant container 4, are immersed in couplant 42.
Probe bracket 3 by locating shaft 1 with go out bobbin 2 and be connected with inspection car, go out the quill shaft that bobbin 2 portals for having probe cable line 6, probe module 5 is fixedly located on probe bracket 3, locating shaft 1 and go out bobbin 2 and be respectively equipped with flange 8,9 with couplant container 4 junction.
Existing probe cable line 6 is all directly draw from going out bobbin 2, then at probe cable line with go out embedding fluid sealant in the middle of bobbin, in the application, use an O-ring seal 7, shown in Fig. 2, described O-ring seal 7 outline is circular, it offer some for the hole 72 through probe cable line 6, preferably, the quantity in hole 72 is the same with the quantity of probe module 5, thus make to separate between probe cable line 6 clear, the external diameter of probe cable line 6 is slightly larger than the internal diameter in hole 72, like this when probe cable line 6 is through hole 72, probe cable line 6 is made tightly to be sandwiched in hole 72, can not leak between probe cable line 6 and O-ring seal 7.The diameter of O-ring seal 7 is slightly larger than the internal diameter going out bobbin 2, and O-ring seal 7 is placed in out in bobbin 2, and therefore O-ring seal 7 is tightly sandwiched in out in bobbin 2, O-ring seal 7 and go out between bobbin 2 and can not leak.Thus ensure the sealing of whole packoff.
During use, probe cable line 6 passes from hole 72, then is put into out in bobbin 2 by O-ring seal 7.When probe module 5 will be changed, as long as O-ring seal 7 from going out bobbin 2 to take out, probe cable line 6 is extracted out from the hole 72 of O-ring seal 7, i.e. replaceable probe module 5.
The foregoing is only the preferred embodiment that the utility model is created; do not create in order to limit the utility model; the any amendment done within all spirit of creating at the utility model and principle, equivalent to replace and improvement etc., all should be included within protection domain that the utility model creates.
