    BACKGROUND OF THE INVENTION
    [0001] The disclosure generally relates to inspection systems and special probes for a substantially round hole inspection system using eddy currents or ultrasound.
    Industrial machines such as gas turbines have numerous parts with holes therein, which require inspection using eddy currents or ultrasound. For example, a bolt hole in a gas turbine engine part may require such inspection to identify cracks, etc. A problem with the use of eddy current and ultrasonic inspection methods is that they require very precise handling of the inspection probe. When inspecting inner surfaces with larger diameters (eg, over 2.5 centimeters), probe handling is very difficult. Another problem is that a probe using a single sensor requires very long inspection times due to the requirements for proper inspection area coverage. In addition, a single sensor probe requires complex handling to ensure adequate test area coverage.

    DETAILED DESCRIPTION OF THE INVENTION
    As set forth above, the disclosure provides probes for a substantially round hole inspection system.
    It is shown in FIG. 1 - 3; for one embodiment, a probe 100 for an inspection system 102 for a substantially round hole in a material is shown. The inspection system 102 may include any currently known or later developed eddy current or ultrasonic inspection system capable of being operatively associated with a probe according to the invention. As is well known, the inspection system 102 includes a control system for sending either an eddy current or an ultrasonic signal through a probe, such as the probe 100 in FIG. 1-3 or the probe 200 in FIG. 4-6, to receive a return signal and analyze the return signal so that the structure of the material over which the signals are transmitted can be analyzed and / or imaged. Such inspection systems 102 are capable, among other things, of identifying defects in the material, such as cracks or other imperfections.
    The term "substantially round hole" as used herein refers to a hole in a material, e.g. In steel, aluminum or another metal or an alloy thereof, which has at least one portion which has a round, oval, circular or approximately circular shape. In one example, the hole may be a threaded opening such as a bolt hole in a portion of a gas turbine. Various other examples will be apparent to those skilled in the art.
    It is shown in FIG. 1, reference is made; The probe 100 may include a flexible plate 110 that is shaped and biased to substantially conform to the shape of a portion 112 of an interior 114 of a substantially circular hole 116 in a material 118. In one embodiment, the flexible plate 110 may comprise a polystyrene substrate; however, various other flexible sheet materials may also be used, such as, but not limited to, polytetrafluoroethylene (PTFE) and vinyls. Multiple sensors 120 may be disposed on the flexible plate 110 so that each sensor 122 may send a non-destructive signal into the material 118 to inspect the substantially circular hole, i. by the inspection system 102 which analyzes a return signal received by the sensors 122. As mentioned, the non-destructive signal may include either an eddy current signal or an ultrasonic signal. Each sensor 122 may take any suitable form based on the type of signal used, e.g. B. the form of any combination of coils for Wirbelström or an ultrasonic transducer for the transmission and reception of ultrasonic signals. In one embodiment, as shown in FIG. 1, multiple sensors 120 extend along a line 124 on the flexible plate 110 and along substantially the entire length of the flexible plate 110. In this way, as the probe 100 enters or exits the hole 116, it will assess at least one half of the hole, e.g. B. at least 180 ° of the round hole. Although a rectilinear arrangement has been shown, other arrangements may be provided depending on the shape of section 112. For example, two lines of sensors, a sinusoidal line, a matrix of sensors, etc. may be used.
    The flexible plate 110 may initially be shaped to be substantially conformed to the shape of the portion 112, e.g. B. by having a certain length and a certain radius of curvature. For example, the polystyrene substrate may have a shape designed to substantially conform to the shape of the portion 112 of the interior 114 of the substantially circular hole 116. For example, if the hole 116 has a diameter of 1.2 centimeters, the flexible plate 110 may have a radius of curvature of 0.6 centimeters (radius of the hole 116) and a length of about 1.9 centimeters (a little more than half of the Circumference of the hole 116). Moreover, as shown in Fig. 2, the flexible plate may be inserted between a first compressed position (dashed line HOC in Fig. 2) adapted to insert the plate into one end of the substantially circular hole 116, and a second, extended position (solid line 110E in FIG. 2), which is such that the plate is substantially conformed to the shape of the portion 112 of the interior 114 of the substantially circular hole 116. In this way, the probe 100 can be easily inserted into the hole 116 in the first, compressed position without the need for expensive handling operations, and can then be released in the second, expanded position so that it expands. In one example, as shown in FIG. 1, the portion 112 may include a substantially semicircular portion of the interior 114 of the substantially circular hole 116, and the flexible plate 110 may be sized to substantially conform to the shape of the substantially semicircular portion of the interior of the substantially circular one Hole is adjusted. Alternatively, as shown in FIG. 2, the portion 112 may be arcuate rather than substantially semicircular when the hole 116 is not precisely circular.
    As shown in FIG. 1 and 2, the probe 100 may also include a probe carrier 130 (only FIG. 2) coupled to the flexible plate 110 for supporting the flexible plate relative to the substantially circular hole 116. A handle 132 may be coupled to the probe carrier 130 to control a position of the probe. The probe carrier 130 and the handle 132 may be made of any material having sufficient strength to handle the position of the flexible plate 110, e.g. B. of a metal or hard plastic. The probe carrier 130 may be coupled to the flexible plate 130 in any manner currently known or later developed, e.g. By mechanical fasteners such as a screw, with adhesive, etc. The probe carrier 130 and handle 132 may be coupled in a similar manner, or may be made as a one-piece structure.
    Although not necessary in all cases, in one embodiment, a guide 135 may be provided which is movable with the flexible plate 110 and relative to a portion 142 (opposite the portion 112) of the interior 114 of the hole 116 to guide the flexible plate along the section. In an embodiment, the guide 135 may include a guide bracket 134 pivotally coupled to the handle 132 at a first end 136 of the track bracket, e.g. B. by means of a bolt. The guide bracket 134 may be positioned within a groove (not shown) within the handle 132 or may simply be pivotally coupled to an outside of the handle. A guide member 138 may be coupled to a second end 140 of the guide bracket 134 to engage the portion 142 of the interior 114 of the substantially circular hole 116 opposite the flexible panel 110. In the illustrated example, the guide member 138 includes a wheel rotatably coupled to the second end 140; however, structures of any type that are capable of pressing against and against the opposing portion 142, e.g. B. by rolling or sliding, are used. For example, a slider or skid of a block of material may also be applicable. The guide member 138 may be made of any material capable of interference, by rolling, sliding or otherwise, with the opposing portion 142, e.g. As a metal or plastic, withstand. The guide carrier 134 may be made of the same material as the probe carrier 130 or handle 132. As shown in FIG. 1, the guide 135 may also include a biasing member 150 for biasing the guide bracket 134 so as to urge the guide member 138 against the opposing portion 142. In this way, the guide member 138 is movable with the flexible plate 110 (and the sensors 120) and relative to the opposing portion 142 to guide the flexible plate 110 along the portion 112 in a substantially conformal fashion. The biasing member 150 may take many forms, e.g. As a spring, a pneumatic piston, a hydraulic piston, etc. The guide support 134 and / or the biasing member 150 can be changed, for. In size, strength, position, etc., to accommodate holes 116 of different sizes. Optionally, control of the biasing member 150 may be performed via the inspection system 102, e.g. B. using pneumatic, electrical or hydraulic control devices.
    As shown in FIG. 1, any lead wires 152 that may be required to connect the inspection system 102 to the sensors 120 or the biasing member 150 may be disposed along or within the handle 132 and / or along or within the probe carrier 130. Any currently known or later developed transition seals or fittings may be used which are required to secure the lead wires with respect to openings, e.g. B. within the handle, or to protect moving parts.
    In operation, the probe 100 then allows, as shown in FIG. 2 and 3, an inspection of a hole 116 by inserting the probe containing sensors 120 into the hole. As the probe 100 is directed into the hole 116, sensors send / receive a suitable signal in about half of the hole, e.g. B. about 180 °, resulting in an inspection results in about half of the hole. After the probe 100 has been fully inserted in one direction, the probe 100 can be rotated through approximately 180 ° and retracted through the hole, resulting in inspection of the remaining half of the hole. During insertion and withdrawal, the flexible plate 110, possibly with the guide member 138, if used, remains in a state well adapted to the shape of the portion 112 of the interior 114 of the hole 116, thereby providing good quality eddy current or ultrasound data Inspection system 102 can be provided.
    It is now shown in FIG. 4-6, wherein another embodiment of a probe 200 for the inspection system 102 for a substantially round hole 116 in a material 118 is illustrated. In this embodiment, the probe 200 may include an elongated sensor carrier 210. The elongated sensor carrier 210 is stretched sufficiently long to ensure complete sensor coverage over a length of the hole 116, that is, all relevant portions of the hole 116 can be evaluated. A bearing plate 212 is configured to rotatably support the elongated sensor carrier 210 at a position in the substantially circular hole 116. As illustrated, the bearing plate 212 positions the elongated sensor carrier 210 centered in the hole 116; However, this is not necessary in all cases, for. B. for elongated, rounded holes. In any event, the bearing plate 212 may include a mounting surface 214 configured to mate with an end 116 of the substantially circular hole 116 to position the elongate sensor carrier 210. The mounting surface 214 may be shaped to mate with the end 116 such that the bearing plate 212 appropriately positions the sensor carrier 210 and may be rotated into the end 116 with the end 116 and the carrier 214 substantially concentric , As shown in FIG. 5, the bearing plate 212 may have at least one passage 218 therethrough to allow lead wires to be connected to sensors 220 (FIGS. 6 and 7) (if necessary), to look into the hole 116, etc. Although FIG four passages are shown, their number can be arbitrary. Although the mounting surface 214 in FIG. 5 is shown as a substantially circular member, the mounting surface 214 need not be contiguous, as circumferentially spaced elements on the bearing plate 212 may be used.
    The elongate sensor carrier 210 is rotatably coupled to the bearing plate 212 by a bearing 222 which can limit the rotation of the elongate sensor carrier 210 to a value slightly greater than 360 ° (eg, 362 °, 365 °, 370 °, etc.), the purpose of this measure being described here. "A little larger than 360 °" can be any amount near 360 °, which ensures that the entire hole has been assessed without a large amount of overlap. The bearing 222 may limit the rotation of the elongated sensor carrier 210 in any known manner, e.g. By means of rotation stops on, in or adjacent to the bearing 222 and / or on, in or beside the support 210. In addition, a starting point may be fixed or keyed to the bearing 222 to ensure that all measurements begin at the same location. The carrier 210, the bearing plate 212 and the bearing 222 may be made of any material that has sufficient strength to support the sensors 220, made of a metal or hard plastic.
    FIG. 6 shows a plan view, and FIG. 7 shows a side view of a sensor mounting surface 230 of the probe 200 of FIG. 4 according to an embodiment of the invention. As illustrated, the sensor mounting surface 230 may be shaped to substantially conform to the shape of a portion 112 (FIG. 4) of the interior 114 (FIG. 4) of a substantially circular hole 116 (FIG. 4). As mentioned above, the portion 112 may include a substantially semicircular portion of the interior 114 of the substantially circular hole 116, and the sensor mounting surface is sized to substantially conform to the shape of at least a portion of the substantially semicircular portion of the interior of the housing Essentially round hole is adjusted. Accordingly, in one embodiment, the sensor mounting surface 230 may have a fixed curvature to accommodate the smallest hole 116, i. Section 112, for which the probe 200 (FIG. 4) can be used. In this case, the sensor mounting surface 230 may be made of a rigid material 232, such as a metal or hard plastic. In another embodiment, the sensor mounting surface 214 may include a flexible plate 234 that is shaped and biased to substantially conform to the shape of the portion of the interior 114 of the substantially circular hole 116. The flexible plate 234 may be made of the same material as the flexible plate 110 described above, e.g. B. from a polystyrene substrate. Like the flexible plate 110, the flexible plate 234 may be flexible between a compressed and an expanded state. The flexible plate 234, like the elongated sensor carrier 210, has a length that ensures complete measurements of the length of the hole 116, and its length can be changed to accommodate different hole lengths.
    As shown in the portion of the plan view of FIG. 6, a plurality of sensors 220 may be disposed on the sensor mounting surface 230. Each sensor 220 may be configured to send a non-destructive signal into the material to inspect the substantially circular hole 116 (FIG. 4). As mentioned above, the non-destructive signal may include an eddy current signal or an ultrasonic signal. In addition, multiple sensors 220 may be provided on the sensor mounting surface 230 in a variety of arrangements to accommodate different holes 116, e.g. For example, in the illustrated embodiment, sensors 220 extend along a longitudinal line on the sensor mounting surface 230, and may extend substantially along an overall length of the sensor mounting surface 230. In one embodiment, the sensor mounting surface 230 may, as shown in the side view of FIG. 7, have a channel 236 along a longitudinal axis thereof. Multiple sensors 220 may be disposed within the channel 236 to protect the sensors 220 in situations where protection is required, such as in a hole 116 having an interior with a rough surface.
    It is again on FIG. 4, incorporated by reference; The probe 200 may also include a biasing element 250 that couples the sensor mounting surface 230 and the elongate sensor carrier 210. The biasing member 250 biases the sensor mounting surface 230 to conform substantially to the shape of the portion 112 of the interior 114 of the substantially circular hole 116. In the illustrated example, the biasing member 250 includes a plurality of pneumatic pistons 252 distributed along a length of the sensor mounting surface 230. Although three pistons 252 are shown, any number may be used to bias the sensor mounting surface 230 sufficiently. In addition, although pneumatic pistons are illustrated, the biasing member may utilize any form of a presently known or later developed biasing system, including but not limited to springs, hydraulic pistons, etc. The size and / or position of the biasing member 150 may be altered to include holes 116 of different size. The biasing element 250, z. Piston 252, may be coupled to sensor carrier 210 and sensor mounting surface 230 using any currently known or later developed solution, e.g. By mechanical fasteners such as hinges, hinges, screws, etc .; Welding; adhesives; etc. Moreover, although the biasing member 250 is illustrated as being comprised of piston 252 having a rectilinear arrangement with respect to the sensor mounting surface 230, the pistons or other biasing members may be circumferentially displaced along the arcuate sensor mounting surface 230 to provide the bias over the circumference of the surface to distribute. Further, although only one piston is shown at each axial position, one or more pistons or other biasing elements may be used at any axial position along the carrier 210.
    In operation, then, as shown in FIG. 4, the probe 200 inspects the hole 116. After the probe 200 has been placed in the hole 116, the biasing member 250 can be activated, e.g. By pressurizing the pistons 252 with pneumatic pressure to ensure that the sensor mounting surface 234 has sufficient contact with, or sufficiently close to, the portion 112 for the sensors 220 to operate. At this time, the inspection system 100 may activate the sensors 220, and the sensor carrier 210 may be rotated to allow the hole 116 to be rotated slightly more than 360 ° (eg, 361 °, 364 °, 369 °, etc.) by rotation of the sensor carrier 210. ) is exposed in its entirety to the sensors 220. In this way, a full inspection of the hole 116 may be made, with the biasing member 250 maintaining a good fit to the shape of the portion 112 of the interior 114 of the hole 116, thereby ensuring good quality eddy current or ultrasonic data for the inspection system 102.
    Each of the embodiments provides information that may be used to estimate the service life of industrial parts having holes 116 formed therein, e.g. B. of gas turbine components to extend.
