Description

Technical Field

[0001] This application relates to the field of nondestructive testing technology, and in particular to a testing device bracket and a nondestructive testing device. Background Technology

[0002] As large composite material components such as wind turbine blades become larger and lighter, their internal structures are becoming increasingly complex. The need to detect internal defects (such as delamination and insufficient adhesive) and damage (such as fatigue cracks) generated during manufacturing and operation is becoming increasingly urgent. Currently, there are many problems when conducting inspections, especially when scanning areas such as the main beam while the blade is in an upright position. First, the blade surface is a complex spatial curved surface with different angles of the tangent plane at different locations, requiring the scanning device to have multi-degree-of-freedom adjustment capabilities. Second, the scanning device itself has a certain weight and size, and is usually fixed to the blade surface by methods such as vacuum adsorption. During adjustment and movement, if it is handled manually, it is not only labor-intensive and requires multiple people to cooperate, but also carries the risk of the device falling due to personnel fatigue or miscoordination, resulting in poor stability and safety.

Numerous specific details are set forth in the following detailed description to provide a comprehensive understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without requiring some of these specific details.

[0024] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art will understand the specific meaning of these terms in this application based on the specific circumstances.

[0025] As large composite material components such as wind turbine blades become larger and lighter, their internal structures are becoming increasingly complex. The need to detect internal defects (such as delamination and missing adhesive) and damage (such as fatigue cracks) generated during manufacturing and operation is becoming increasingly urgent. Phased array ultrasonic testing technology, due to its high precision and efficiency, is widely used for non-destructive testing of such structures. To perform the test, a scanning device equipped with a probe is typically required to be stably attached to the surface area to be inspected and moved along a preset path.

[0026] Based on this, the applicant discovered that current inspection practices, especially when scanning areas such as the main beam with the blades in a vertical orientation (i.e., the direction from the leading edge to the trailing edge is vertical), present numerous challenges. First, the blade surface is a complex spatial curved surface, with varying tangential angles (i.e., normal angles along the blade's axial and chordal directions) at different locations, requiring the scanning device to possess multi-degree-of-freedom adjustment capabilities to conform to the curved surface in real time. Second, the scanning device itself has a certain weight and size, and is typically fixed to the blade surface using methods such as vacuum adsorption. During adjustment and movement, relying solely on manual handling is not only labor-intensive and requires multiple people, but also carries the risk of the device falling due to personnel fatigue or coordination errors, resulting in poor stability and safety. Furthermore, existing dedicated supports or AGV integrated support platforms are often structurally complex, inconvenient to adjust (e.g., using multiple separate lead screws for adjustment, making synchronization difficult and lacking intuitiveness), inflexible in movement (large turning radius, high requirements for ground flatness), or cumbersome to assemble and disassemble with the scanning device, severely impacting the overall efficiency of the inspection operation.

[0027] To address the aforementioned issues, this application provides a testing device bracket and a non-destructive testing device, which can effectively improve the flexibility of the testing device's movement and scanning.

[0028] It is understood that the following embodiments of this application are only used as examples of applying the testing device bracket and non-destructive testing equipment to the testing of wind turbine blades. However, it should be understood that the testing device bracket and non-destructive testing equipment provided in the embodiments of this application are not limited to the following embodiments, and can also be used in other occasions where non-destructive testing of structural components with complex shapes is required, and to protect them.

[0029] To better understand this application, the following will be combined with... Figures 1 to 4 The testing device bracket and non-destructive testing equipment provided in the embodiments of this application are described in detail.

[0030] Please refer to the following: Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a detection device bracket provided in one embodiment of this application. Figure 2 This is a partial structural schematic diagram of a detection device bracket provided in one embodiment of this application. Figure 3 This is a partial structural schematic diagram of the detection device bracket provided in another embodiment of this application.

[0031] In a first aspect, according to an embodiment of this application, a testing device support 100 is provided for supporting a testing device 201, comprising: a support assembly 10; a lifting assembly 20, including a first lifting member 21 and a second lifting member 22, the first lifting member 21 being mounted on one side of the support assembly 10 in a first direction X, the second lifting member 22 being movably connected to the first lifting member 21 and capable of moving relative to the first lifting member 21 along the first direction X; a support assembly 30 being rotatably connected to the second lifting member 22, the support assembly 30 being capable of rotating relative to the lifting assembly 20 about an axis extending along a second direction Y, the first direction X intersecting the second direction Y, the side of the support assembly 30 away from the support assembly 10 having a support surface, on which the testing device 201 can be placed; and a drive assembly 40 being mounted on the lifting assembly 20 and connected to the support assembly 30, the drive assembly 40 being capable of driving the support assembly 30 to rotate and adjusting the pitch angle of the testing device 201.

[0032] This application provides a testing device support 100 for supporting the testing device 201 to perform scanning inspections on structural components such as blades, for example, non-destructive testing using a phased array ultrasonic probe. The testing device support 100 mainly includes a load-bearing component 10, a lifting component 20, a support component 30, and a drive component 40.

[0033] The load-bearing component 10 forms the base of the entire support structure, which is used to support other components and provide good stability. The load-bearing component 10 may have a certain area size to reduce the possibility of the support structure tipping over during use or movement.

[0034] The lifting assembly 20 is connected to one side of the support assembly 10 in a first direction X, which can be a vertical direction perpendicular to the support surface of the support assembly 10 or the ground. The lifting assembly 20 includes a first lifting member 21 and a second lifting member 22, which are movably connected. The first lifting member 21 is fixedly mounted on the support assembly 10, while the second lifting member 22 can move relative to the first lifting member 21 along the aforementioned first direction X. Thus, the height of the working end of the entire support can be adjusted by the lifting and lowering of the second lifting member 22.

[0035] The support assembly 30 is rotatably connected to the second lifting member 22. Specifically, the support assembly 30 can rotate relative to the lifting assembly 20 about an axis extending along a second direction Y, thereby adjusting the pitch angle of itself and the detection device 201 clamped on the support assembly 30. The second direction Y intersects the first direction X, and may further be perpendicular to each other. The second direction Y may also be parallel to the horizontal direction. The side of the support assembly 30 away from the bearing assembly 10, which can be considered the upper side of the support assembly 30, has a support surface. The detection device 201 to be supported, such as a phased array scanner, can be placed on this support surface and move synchronously with at least a portion of the support assembly 30.

[0036] It is understood that the support component 30 may be able to rotate relative to the lifting component 20 in one of the aforementioned directions, or the support component 30 may be able to rotate at least partially relative to the lifting component 20 in other directions, in order to further improve the flexibility and range of adjustment.

[0037] The drive assembly 40 is mounted on the lifting assembly 20 and connected to the support assembly 30. The drive assembly 40 can output torque to drive the support assembly 30 to rotate about the axis parallel to the second direction Y, thereby adjusting the pitch angle of the detection device 201 placed on the support surface accordingly. The drive assembly 40 can be an electric / hydraulic drive structure with its own power source, or it can be a transmission structure driven by an operator.

[0038] In this embodiment, the support frame utilizes the lifting assembly 20 to achieve a wide range of vertical position adjustments for the detection device 201, adapting to detection areas of varying heights. Simultaneously, the drive assembly 40 drives the support assembly 30 to rotate, enabling precise and controllable adjustment of the pitch angle of the detection device 201. These two core degrees of freedom adjustment functions allow operators to easily adjust the detection device 201 to the required angle and height for initial contact with a local surface of a complex curved structure (such as the main beam area of ​​a wind turbine blade), preparing for subsequent precise adsorption or contact scanning. Furthermore, this eliminates the need for manual hand-held movement of the detection device 201, effectively improving operational flexibility and detection efficiency.

[0039] In some optional embodiments, the first lifting member 21 includes multiple lifting support rods 211 extending along the first direction X, and the second lifting member 22 includes a connecting part 221 and a supporting part 222; the connecting part 221 is movably connected to the multiple lifting support rods 211 respectively, the supporting part 222 extends at least partially along the third direction Z, and the support assembly 30 is rotatably connected to the supporting part 222, and the first direction X, the second direction Y and the third direction Z are arranged to intersect each other.

[0040] The first lifting member 21 in this embodiment includes multiple lifting support rods 211 extending along the first direction X. These lifting support rods 211 are arranged parallel to each other and can be arranged at intervals along the second direction Y. These lifting support rods 211 are used to provide stable guidance for the entire lifting movement. They can be fixedly connected to the bearing component 10 by welding or detachably connected by fasteners.

[0041] The second lifting member 22 further includes a connecting portion 221 and a supporting portion 222. The connecting portion 221 is movably connected to multiple lifting support rods 211 via pulleys 214, sliders, linear bearings, or sleeves, ensuring that the second lifting member 22 can slide smoothly up and down along the lifting support rods 211. The supporting portion 222 extends from the connecting portion 221 to one side, at least partially extending along a third direction Z, to facilitate the support assembly 30 and reduce the possibility of the support assembly 30 interfering with other structures during lifting. The first direction X, the second direction Y, and the third direction Z intersect each other, and may further be perpendicular to each other. The support assembly 30 is rotatably connected to the aforementioned supporting portion 222 extending along the third direction Z.

[0042] For example, the first lifting member 21 may include two lifting support rods 211, which may be provided with a sliding groove extending along the first direction X. The second lifting member 22 is provided with a pulley 214 at the connecting part 221. The pulley 214 may be disposed in the sliding groove and can slide in the groove to provide auxiliary fiber functions in other directions while realizing relative movement along the first direction X.

[0043] The aforementioned frame structure is rigid and has good guidance, and can withstand the torque generated by the detection device 201 and the support component 30, so that the lifting process is smooth and without shaking.

[0044] In some alternative embodiments, the support assembly 30 includes a support member 31 and a rotating member 32 connected to each other, with a support surface disposed on the support member 31, and the support member 31 being detachably connected to the detection device 201; the rotating member 32 is at least partially located on the side of the support portion 222 opposite to the support assembly 10 and is rotatably connected to the support portion 222.

[0045] Optionally, the support assembly 30 includes a support member 31 and a rotating member 32 connected to each other. To improve stability, the connection between the two can be either welded or integrally formed. The support surface is disposed on the support member 31, which is designed to be detachably connected to the detection device 201, for example, through a slot, positioning pin, or quick clamp, ensuring that the detection device 201 remains in a fixed position relative to the support member 31 during adjustment and movement.

[0046] The rotating component 32 is a key component for achieving a rotatable connection between the support assembly 30 and the second lifting component 22. At least part of its structure is located on the side of the support portion 222 away from the support assembly 10, and forms a rotating pair with the support portion 222 through structures such as bearings and rotating shafts. The support portion 222 supports the rotating component 32, and the rotating component 32 in turn provides support to the support component 31, thereby enabling the entire working end structure, including the support component 31 and the detection device 201 on it, to rotate freely around an axis parallel to the second direction Y.

[0047] The aforementioned structure enables the support component 30 to maintain a relatively stable position during rotation and provides reliable support to the detection device 201.

[0048] In some optional embodiments, the support member 31 includes a support base plate 311 and a plurality of fixing parts 312 connected to the support base plate 311. The support base plate 311 is plate-shaped and extends along the second direction Y. The plurality of fixing parts 312 are arranged in pairs. The plurality of pairs of fixing parts 312 are spaced apart along the second direction Y. Each pair of fixing parts 312 is spaced apart along the third direction Z and is arranged facing each other. The fixing part 312 has a fixing hole that passes through along the third direction Z.

[0049] Optionally, the support member 31 includes a support base plate 311 and a plurality of fixing parts 312, wherein the support base plate 311 is a plate-shaped member used to support the detection device 201, and its main extending direction is the second direction Y. The plurality of fixing parts 312 are connected to the support base plate 311 and are used to define the position of the detection device 201.

[0050] Specifically, multiple fixing parts 312 are arranged in pairs, and the multiple pairs of fixing parts 312 are arranged at intervals along the extension direction of the support base plate 311. The two individual units in each pair of fixing parts 312 are spaced apart and facing each other along the third direction Z. The part of the support base plate 311 connecting the two forms a U-shaped structure that can be limited in the first direction X and the third direction Z.

[0051] Furthermore, each fixing part 312 has a fixing hole extending through in the third direction Z for inserting a fixing pin and providing a limit on the other side in the first direction X. It is understood that the detection device 201 typically includes a scanning frame and a detection probe movable along the scanning frame, wherein the scanning frame can be placed on the support base plate 311 and sandwiched between two units in each pair of fixing parts 312. Then, by inserting the fixing pin into the fixing hole, quick locking can be achieved, and the relative position between the detection device 201 and the support assembly 30 can be stabilized and prevented from shifting.

[0052] The aforementioned structure enables the rapid clamping and release of the detection device 201, and the multiple pairs of fixing parts 312 arranged at intervals along the second direction Y provide multiple clamping points, further enhancing the stability and balance of the load.

[0053] In some optional embodiments, the second lifting member 22 includes a plurality of support portions 222 spaced apart along the second direction Y, and a rotating member 32 is disposed between adjacent support portions 222; the support portion 222 is provided with a rotating groove on the side away from the bearing assembly 10, the rotating groove is arc-shaped and recessed along the first direction X, and the rotating member 32 includes a rotating wheel 321, the rotating wheel 321 is disposed in the rotating groove and can rotate in the rotating groove about an axis parallel to the second direction Y.

[0054] Optionally, to improve the stability of support and rotation, the second lifting member 22 may include a plurality of support portions 222 spaced apart along the second direction Y, and the rotating member 32 in the support assembly 30 is disposed between these two adjacent support portions 222, thereby enabling the opposite sides of the support assembly 30 to be rotatably connected to at least one support portion 222 respectively.

[0055] The support portion 222 can be a rod-shaped member extending along a third direction Z. A rotating groove is machined on the side of each support portion 222 opposite to the bearing assembly 10, i.e., on the upper surface of the support portion 222. The rotating groove has an arc-shaped edge in the cross-sectional shape formed in a cross-section perpendicular to the second direction Y, and is recessed along the first direction X. Correspondingly, the rotating member 32 includes a rotating wheel 321, which can be disposed in the rotating groove and can roll freely within the rotating groove about an axis parallel to the second direction Y.

[0056] It is understandable that the central angle corresponding to the arc-shaped rotating groove should be less than or equal to 180° so that the rotating wheel 321 can quickly disengage from or enter the rotating groove. When setting the rotating wheel 321, the number of rotating wheels 321 can be matched with the number of rotating grooves and correspond one-to-one. The diameter of each rotating wheel 321 and the diameter and depth of the rotating groove can be the same so that the rotating part 32 is subjected to uniform force.

[0057] This "wheel-groove" rotating connection method results in low frictional resistance and smooth rotation, enabling sensitive and easy adjustment of the pitch angle of the support component 30°. Simultaneously, the arc-shaped rotating groove naturally limits the rolling range of the rotating wheel 321, further improving rotational stability.

[0058] In some optional embodiments, the rotating member 32 further includes a rotating rod 322 and a counterweight 323. The counterweight 323 and the rotating wheel 321 are both connected to the rotating rod 322, which extends along the second direction Y. The counterweight 323 and the support member 31 are respectively connected to the two opposite sides of the rotating rod 322 along the third direction Z, and the rotating wheel 321 is connected to the opposite ends of the rotating rod 322 in the second direction Y.

[0059] Optionally, the rotating component 32 may further include a rotating rod 322 and a counterweight 323. The counterweight 323 and the aforementioned rotating wheel 321 are both connected to the rotating rod 322, which itself extends along the second direction Y. The rotating rod 322 can serve as the main structural component and provide the main connection and load-bearing functions.

[0060] Furthermore, the counterweights 323 in the support member 31 and the rotating member 32 are respectively connected to opposite sides of the rotating rod 322 along the third direction Z. In other words, the counterweights 323 and the support member 31 are located on opposite sides of the rotating rod 322 in its own radial direction, and the line connecting their centers of gravity can be chosen to pass through the central axis of the rotating rod 322. The rotating wheels 321 are connected to opposite ends of the rotating rod 322 in the second direction Y, and are respectively embedded in the rotating grooves of the two support portions 222. Thus, the detection device 201 can be placed on the support member 31 and maintained in balance with the assistance of the counterweights 323.

[0061] For example, the counterweight 323 can be fan-shaped, semi-circular, arc-shaped, etc. Taking the counterweight 323 as an example, its two ends can be connected to the area of ​​the rotating rod 322 near the two rotating wheels 321 respectively, and bend and protrude in the direction away from the rotating rod 322 along the third direction Z, so that it has a certain distance from the rotating rod 322 in the area near the center, which facilitates the setting of other connection structures.

[0062] The counterweight 323 allows the center of gravity of the entire support assembly 30 to be closer to or through the central axis of the rotating rod 322, thereby significantly reducing the torque required to drive the support assembly 30 to rotate, making manual adjustment easier. At the same time, it can improve the static stability of the support assembly 30 at any pitch angle, preventing it from rotating on its own without external force due to the shift of the center of gravity. In other words, by setting the counterweight 323, it can provide the ability of "self-locking" and "position holding", further improving the ease of use of the detection device bracket 100.

[0063] In some optional embodiments, the support portion 222 is also connected to a plurality of limiting portions 223, which extend along a third direction Z and are spaced apart along a second direction Y. Along the first direction X, the orthographic projection of the support member 31 partially overlaps with the orthographic projection of the limiting portion 223. The support member 31 is also capable of rotating relative to the second lifting member 22 about an axis parallel to the third direction Z, and the limiting portion 223 can limit the rotation range of the support member 31.

[0064] The rotating member 32 in this embodiment further includes a plurality of limiting portions 223, which can be connected to the supporting portion 222. These limiting portions 223 extend along a third direction Z and are spaced apart along a second direction Y. The limiting portions 223 may be rod-shaped members and may be provided in a one-to-one correspondence with the supporting portion 222. They may be connected to the side surface of the supporting portion 222 facing the bearing assembly 10 along the first direction X.

[0065] Based on this, the support member 31 can not only rotate with the entire support assembly 30 around an axis parallel to the second direction Y for pitch adjustment, but also rotate relative to the second lifting member 22 around an axis parallel to the third direction Z to achieve high and low swinging at both ends. The latter rotational degree of freedom can be used to fine-tune the yaw angle of the detection device 201 around its own axis to match the extension direction of the area to be scanned.

[0066] Based on this, along the first direction X, the orthographic projection of the support member 31 overlaps with the orthographic projection of the limiting part 223. That is, the limiting part 223 can limit the angle of the support member 31, including in the pitch adjustment direction and the end swing direction. The limiting part 223 can extend from the side to the support member 31. When the support member 31 rotates about an axis parallel to the third direction Z, it will contact the limiting part 223, thereby limiting the angle range of the support member 31. While maintaining a certain alignment adjustment range, it prevents excessive rotation that could cause interference between the detection device 201 and other parts of the bracket or excessive twisting of connecting cables. The specific angle range can be within 10° of clockwise or counterclockwise tilt relative to the horizontal direction.

[0067] Meanwhile, the limiting part 223 connected to the support part 222 can also prevent the support member 31 from tilting too far downward and reduce the possibility of the support member 31 flipping forward and falling, thereby improving the overall reliability of the bracket.

[0068] In some alternative embodiments, along the direction from the support component 30 to the carrier component 10, the distance between the limiting portion 223 and the first lifting member 21 on the side of the limiting portion 223 away from the lifting component 20 in the third direction Z tends to decrease.

[0069] Along the direction from the support component 30 to the carrier component 10, in this embodiment, the end face of the limiting portion 223 on the side away from the lifting component 20 in the third direction Z can be inclined. Specifically, the distance between this end face and the first lifting member 21 can gradually decrease in the aforementioned direction. For example, this end face of the limiting portion 223 can be designed as a slope or a concave arc surface.

[0070] Taking the side of the limiting part 223 away from the lifting component 20 in the third direction Z as an example, the angle between this plane and the first direction X can be about 45°.

[0071] The aforementioned design allows for a gradually narrowing clearance space to be formed between the limiting part 223 and the lifting support rod 211. When the support member 31 tilts forward, this clearance space formed at the front end of the limiting part 223 can prevent the probe in the detection device 201 from rigidly colliding with it during movement, thereby ensuring smooth movement and preventing damage to the detection device 201.

[0072] In some optional embodiments, the first lifting member 21 further includes a hydraulic lifting part 212, a traction cable 213, and a pulley 214. The hydraulic lifting part 212 is capable of extending and retracting along a first direction X. The pulley 214 is installed at the end of the hydraulic lifting part 212 away from the bearing component 10. The traction cable 213 passes around the pulley 214, and one end of the traction cable 213 is connected to the second lifting member 22, and the other end is connected to the lifting support rod 211.

[0073] Optionally, the first lifting member 21 in this embodiment may include a hydraulic lifting section 212, a traction cable 213, and a pulley 214. The hydraulic lifting section 212 may be a manual hydraulic cylinder or an electro-hydraulic push rod, etc., and is capable of extending and retracting along a first direction X. The pulley 214 is installed at the end of the hydraulic lifting section 212 away from the supporting component 10, i.e., its top end, and is capable of rising and falling with the extension and retraction of the hydraulic lifting section 212.

[0074] The traction cable 213 can be a steel wire rope, chain, or high-strength cable, etc. The traction cable 213 is wound around the pulley 214, and one end of the traction cable 213 is connected to the second lifting member 22, for example, it can be connected to the connecting part 221 therein, and the other end is connected to the lifting support rod 211. For example, it can be directly connected to the lifting support rod 211, or it can be connected to a crossbar fixed in a position relative to the lifting support rod 211, that is, indirectly connected to the lifting support rod 211.

[0075] In this embodiment, when the hydraulic lifting section 212 extends upward, the pulley 214 at its top rises accordingly. Since one end of the traction cable 213 is fixed, the rise of the pulley 214 pulls the end of the traction cable 213 connected to the second lifting member 22, thereby lifting the second lifting member 22 and the entire support assembly 30 upward. Conversely, when the hydraulic lifting section 212 retracts, the second lifting member 22 descends under the weight of the support assembly 30. By employing the aforementioned principle of the movable pulley 214, a large lifting stroke can be achieved with a small hydraulic lifting stroke, and the transmission is smooth and reliable.

[0076] In some optional embodiments, the first lifting member 21 further includes a lifting controller 215 for controlling the extension and retraction of the hydraulic lifting section 212; the drive assembly 40 includes a control handwheel 41, a first transmission rod 42, a second transmission rod 43, and a reducer 44, wherein the first transmission rod 42 is connected between the support assembly 30 and the reducer 44, and the second transmission rod 43 is connected between the reducer 44 and the control handwheel 41; wherein the control handwheel 41 and the lifting controller 215 are both located on the side of the lifting support rod 211 away from the support assembly 30 along the third direction Z.

[0077] Optionally, the first lifting component 21 may also include a lifting controller 215 for controlling the extension and retraction of the hydraulic lifting unit 212. The lifting controller 215 may be a combination of a manual pump handle, an electric switch, or a pressure pedal and a pressure relief valve.

[0078] The drive assembly 40 includes a control handwheel 41, a first transmission rod 42, a second transmission rod 43, and a reducer 44. The first transmission rod 42 connects the rotating part 32 of the support assembly 30 to the output end of the reducer 44. The second transmission rod 43 connects the input end of the reducer 44 to the control handwheel 41. These four components are sequentially connected, transmitting the initial rotation of the control handwheel 41 to the first transmission rod 42, and then to the rotating part 32, driving it to rotate. The reducer 44 increases torque and enables fine adjustment, meaning it can reduce the output of one revolution of the second transmission rod 43 to less than one revolution of the first transmission rod 42. For example, the central angle between the two rotations can be 5:1 or 3:1, etc.

[0079] Based on this, the control handwheel 41 and the lifting controller 215 are both located on the side of the lifting support rod 211 away from the support component 30 along the third direction Z. Thus, the operator can stand on the same side of the bracket to operate the lifting controller 215 to adjust the height and operate the control handwheel 41 to adjust the pitch angle. Simultaneous adjustment is optional. The main position adjustment can be completed without walking back and forth around the equipment, which greatly improves the convenience and efficiency of operation and conforms to ergonomics.

[0080] In some alternative embodiments, the support assembly 10 includes a support member 11 and a moving wheel 12, with the support member 11 connected between the moving wheel 12 and the lifting assembly 20.

[0081] Optionally, the support component 10 in this embodiment may include a support member 11 and casters 12. The support member 11 may be a platform frame or a plate-shaped base, and multiple casters 12 are mounted on the bottom of the support member 11. The lifting component 20 is connected to the upper surface of the support member 11. The casters 12 may be omnidirectional wheels with brakes and / or self-driving power wheels.

[0082] Optionally, the carrier 11 may be provided with handrails on opposite sides in the second direction Y, so that the operator can push the carrier assembly 10 from both sides to move and / or make large coarse adjustments to the angle between the carrier assembly 10 and the object being tested.

[0083] This movable structure with casters 12 allows the entire support to be easily moved and turned within the workshop or testing area, quickly positioned near the blade to be inspected, further improving the overall flexibility of the support.

[0084] Please see Figure 4 , Figure 4 This is a partial structural schematic diagram of a non-destructive testing device provided in one embodiment of this application.

[0087] The detection device 201 includes a scanning detection component 50, such as a phased array ultrasonic probe and its mechanical scanning frame, and a control host 60. The scanning detection component 50 is communicatively connected to the control host 60, including direct connection via cable or remote wireless connection via a signal transceiver module. The control host 60 is placed on the bearing surface of the support assembly 10, and the scanning detection component 50 is placed and fixed on the support surface of the support assembly 30. Optionally, to place the mechanical scanning frame on the support surface and enable the phased array ultrasonic probe to reciprocate along the length of the support surface on the scanning frame, suction cups or other structures for auxiliary connection and fixation can be provided at opposite ends of the scanning frame itself.

[0088] Optionally, a toolbox, a water tank for holding coupling agent, etc. can also be placed on the carrier 11. This application does not make specific limitations on this without affecting the lifting operation of the lifting assembly 20 and the rotation of the support assembly 30.

[0089] The aforementioned placement method allows the device to integrate a flexible mechanical adjustment bracket with the testing device 201, forming a mobile and quick-adjustment semi-automatic testing workstation. Operators can easily adjust the scanning and testing piece 50 to a suitable height and angle, ensuring initial contact with the blade surface, and then activate the scanning device for automatic testing. This significantly reduces labor intensity and improves the safety and consistency of the testing operation.
