Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to a magnetic adsorption wheel and a weld seam testing device. Background Technology

[0002] With the development of science and technology, the use of large steel structure curved surfaces in engineering operations is constantly increasing, such as wind turbine towers and tower-type chemical tanks. These often require regular inspection or cleaning, but manual inspection and cleaning would incur significant costs. Therefore, automated transport equipment is needed to transport the work equipment to the corresponding work surfaces. However, most current work equipment transport devices use wheeled magnetic adsorption wall-climbing trolleys. These trolleys have poor adaptability to curved or uneven surfaces, exhibiting insufficient adsorption force and poor stability, thus limiting their applicability. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to overcome the shortcomings of the prior art and provide a magnetic adsorption wheel and weld inspection device, which can be applied to different types of metal walls, and is suitable for curved or uneven metal walls, and can solve the problem of insufficient adsorption force.

[0004] This invention provides the following technical solution:

[0005] According to a first aspect disclosed in this invention, a magnetic adsorption wheel is provided, the magnetic adsorption wheel comprising:

[0006] A first wheel body includes two sets of finned portions, which have an inter-wheel gap on a first axis. Each set of finned portions comprises multiple finned portions, and each set is circumferentially distributed along the first axis.

[0009] A wheel hub, connected to the drive component, the drive component capable of driving the wheel hub to rotate; wherein...

[0010] The two opposite ends of the fin portion are an elastic end and a connecting end, respectively. The elastic end is close to the wheel gap and can undergo elastic deformation to move closer to or away from the wheel hub. The connecting end is away from the wheel gap and is connected to the wheel hub.

[0011] Furthermore, the end of the fin portion near the wheel gap is configured as a thin-walled structure, and there is a deformation gap between the end of the fin portion near the wheel gap and the wheel hub.

[0012] Furthermore, the fin portion includes:

[0013] Contact module;

[0014] An elastic module is provided, wherein the contact module is connected to the wheel hub through the elastic module, and there is a gap between the contact module and the wheel hub. The elastic module is configured to undergo elastic deformation, wherein the elastic module forms the connection end and the contact module forms the elastic end.

[0015] Furthermore, a permanent magnet is provided on the side of the elastic end facing the wheel hub, and a tire surface is formed on the side of the elastic end away from the wheel hub.

[0016] Furthermore, the Young's modulus of the elastic module is 0.12 GPa to 0.7 GPa.

[0017] Furthermore, the number of wheel hubs is one pair, and the pair of wheel hubs are coaxially arranged;

[0018] The drive unit includes a pair of motors and a frame, wherein the pair of motors are mounted on the frame and each of the pair of motors is connected to a wheel hub.

[0019] According to a second aspect of the present invention, a weld inspection device is provided, the weld inspection device comprising the aforementioned magnetic adsorption wheel.

[0020] Furthermore, the weld inspection device also includes:

[0021] The vehicle frame is connected to the magnetic adsorption wheel;

[0022] An ultrasonic testing component is mounted on the vehicle frame and is capable of detecting weld seams.

[0023] The ultrasonic testing component includes:

[0024] A support wheel and a damping frame, wherein the support wheel is rotatably connected to the damping frame, and the axis of the support wheel is parallel to the axis of the first wheel body;

[0025] Shock absorber, the damping frame is connected to the vehicle frame via the shock absorber;

[0026] An ultrasonic transceiver is mounted on the damping frame.

[0027] Furthermore, the support wheel includes:

[0028] The second wheel is a magnetic wheel; and the surface of the second wheel has an annular groove that extends circumferentially along the first wheel.

[0029] Furthermore, the weld inspection device also includes a coating component, which is mounted on the vehicle frame and is capable of applying coupling agent;

[0030] The applicator is located upstream of the ultrasonic transceiver in the direction of movement, and the ultrasonic transceiver is located on the movement path of the applicator.

[0031] Furthermore, the applicator includes:

[0032] A coupling agent cartridge, which stores the coupling agent, is connected to the vehicle frame, and has a channel at the bottom of the cartridge that allows the coupling agent to flow out.

[0033] A flexible applicator is installed at one end of the coupling agent box that has a channel.

[0034] Furthermore, the shock absorber includes:

[0035] A pair of first dampers, each of which is parallel to a first reference plane, with opposite ends of the first dampers hinged to the vehicle frame and the damping frame, respectively; wherein the axis of the support wheel is parallel to the first reference plane;

[0036] A pair of second dampers, each of which is parallel to the second reference plane, with opposite ends of the second dampers connected to the vehicle frame and the damping frame, respectively; wherein the second reference plane is perpendicular to the first reference plane;

[0037] The axes of the first pair of dampers intersect with the second reference plane, and the axes of the second pair of dampers intersect with the first reference plane.

[0038] The embodiments of the present invention have the following advantages:

[0039] When using the magnetic adsorption wheel provided by this invention, a gap is formed between the ends of the two sets of fins that are close to each other. The ends of the fins near the gap can elastically deform radially from the first wheel body. In other words, when the metal wall surface is uneven or curved, the two sets of fins can adaptively deform according to the shape of the metal wall surface, thereby adapting to the metal wall surface and increasing the contact area between the first wheel body and the metal wall surface. For example, when the metal wall surface is uneven, the fins can deform individually or in multiple ways; when the metal wall surface is curved, an annular groove or annular protrusion can be formed between the two sets of fins to adapt to the concave or convex curved surface. Furthermore, because the two sets of fins are staggered, the wheel surface formed by the two sets of fins is continuous, thus avoiding magnetic blind zones. This ensures that a stable magnetic attraction force is provided at all points on the wheel surface when in contact with the metal wall surface, and avoids discontinuity in the wheel surface, reducing vibration during the movement of the magnetic adsorption wheel and improving the smoothness of its movement.

[0040] This device can be applied to various types of metal walls, including curved or uneven surfaces, and solves the problem of insufficient adsorption force. It requires no external power source and uses simple mechanical and physical principles to solve the originally complex problem of aligning the normal to curved surfaces. This significantly reduces the cost of large steel structure surface operations, effectively improves the efficiency of such operations, significantly simplifies the complexity of the work, and greatly enhances the safety of personnel and equipment.

[0041] Furthermore, the present invention also relates to a weld inspection device. Since the magnetic adsorption wheel has the above-mentioned technical effects, the weld inspection device including the magnetic adsorption wheel should have the same technical effects, which will not be elaborated here.

[0051] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0052] It should be noted that when an element is said to be "fixed" to another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected" to another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly" on another element, there is no intervening element.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0054] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0056] In related technologies, with the development of science and technology, the number of large steel structure curved surfaces used in engineering operations is constantly increasing, such as the 270 wind turbine tower and tower-type chemical tanks. These often require regular inspection or cleaning, and manual inspection and cleaning would incur significant costs. Therefore, automated transport equipment is needed to transport the work equipment to the corresponding work surface. However, most work equipment transport devices use wheeled magnetic adsorption wall-climbing trolleys. But these wheeled magnetic adsorption wall-climbing trolleys have poor adaptability to curved or uneven surfaces. During operation, the contact area between the magnetic wheels of the wheeled magnetic adsorption wall-climbing trolley and the curved or uneven surface fluctuates greatly, resulting in insufficient adsorption force and poor stability, thus limiting their applicability.

[0057] In other words, the structure of the wheeled magnetic adsorption wall-climbing vehicle mainly uses permanent magnets, which are distributed around the wheels. During movement, this method is usually only applicable to flat metal walls. When the metal wall is curved or uneven, the movement is likely to be restricted.

[0058] like Figure 2 and Figure 3As shown, in order to solve the above-mentioned technical problems, according to the first aspect disclosed in this invention, a magnetic adsorption wheel is provided. The magnetic adsorption wheel 200 includes a first wheel body and a driving member. The first wheel body includes two sets of fin portions 220, which have an inter-wheel gap 250 on a first axis. Each set of fin portions 220 has a plurality of fin portions, and each set of fin portions 220 is evenly distributed circumferentially along the first axis. The two sets of fin portions 220 are staggered so that all the fin portions 220 can form a continuous wheel surface of the first wheel body. The fin portions 220 are configured such that at least the portion near the inter-wheel gap 250 is capable of elastic deformation, and the portion of the fin portion 220 at least near the inter-wheel gap 250 is magnetic. The driving member is connected to the first wheel body and can drive the first wheel body to rotate.

[0059] In other words, both sets of fin sections 220 are evenly distributed circumferentially along the first axis, and the two sets of fin sections 220 are staggered. It is easy to understand that this ensures that the contact area between any position of the wheel surface of the first wheel and the metal wall surface has sufficient magnetic attraction. Clearly, when the gap between adjacent fin sections 220 in one set faces the metal wall surface, the fin sections 220 in the other set can precisely contact the metal wall surface, thereby eliminating the magnetic blind zone and preventing detachment from the metal wall surface due to weaker magnetic attraction when the gap between adjacent fin sections 220 faces the metal wall surface.

[0060] For example, the width of the fin portion 220 and the gap width between adjacent fin portions 220 are adjusted so that the width of the fin portion 220 is greater than the gap width between adjacent fin portions 220.

[0061] The presence of a wheel gap 250 between the two sets of fin portions 220 allows the portions of the two sets of fin portions 220 near the wheel gap 250 to elastically deform, thus preventing interference during elastic deformation. For example, a groove can be formed to accommodate a convex metal wall surface; or a protrusion can be formed to accommodate a concave metal wall surface. Clearly, the gaps between adjacent fin portions 220 and the wheel gap 250 can accommodate uneven metal wall surfaces. When foreign objects protrude from the metal wall surface, the gaps between adjacent fin portions 220 and the wheel gap 250 can also accommodate the protrusions or deformations, providing clearance.

[0062] It should be noted that the fin portion 220 is magnetic, so that it can generate a magnetic attraction when it comes into contact with the metal wall surface, thereby keeping the first wheel body able to adhere to the metal wall surface. For example, a magnet can be provided in the fin portion 220 to make it magnetic; or, a portion of the fin portion 220 can be fabricated using a magnet, which will also make the fin portion 220 magnetic. No specific limitation is made here, as long as it is possible to make the fin portion 220 magnetic.

[0063] Furthermore, the driving component is used to drive the first wheel to rotate, that is, to drive the wheel surface formed by the aforementioned fin portion 220 to rotate, thereby enabling the first wheel to move on the metal wall surface. When the wheel surface rotates, the fin portion 220 alternately contacts the metal wall surface.

[0064] Using the magnetic adsorption wheel provided by this invention, a wheel gap 250 is formed between the ends of the two sets of fin portions 220 that are close to each other. The ends of the fin portions 220 near the wheel gap 250 can undergo elastic deformation in the radial direction of the first wheel body. That is, when the metal wall surface is uneven or curved, the two sets of fin portions 220 can adaptively deform according to the shape of the metal wall surface, thereby adapting to the metal wall surface and increasing the contact area between the first wheel body and the metal wall surface. For example, when the metal wall surface is uneven, the fin portions 220 can deform individually or in multiples; when the metal wall surface is curved, an annular groove or annular protrusion can be formed between the two sets of fin portions 220 to adapt to the concave or convex curved surface. In addition, the two sets of fins 220 are staggered to ensure that the wheel surface formed by the two sets of fins 220 is continuous, that is, to avoid the existence of magnetic blind spots, to ensure that a stable magnetic attraction force can be provided when the wheel surface contacts the metal wall, and to avoid the discontinuity of the wheel surface, thereby reducing the vibration when the magnetic adsorption wheel 200 moves and improving the smoothness of the movement of the magnetic adsorption wheel 200.

[0065] This device can be applied to various types of metal walls, including curved or uneven surfaces, and solves the problem of insufficient adsorption force. It requires no external power source and uses simple mechanical and physical principles to solve the originally complex problem of aligning the normal to curved surfaces. This significantly reduces the cost of large steel structure surface operations, effectively improves the efficiency of such operations, significantly simplifies the complexity of the work, and greatly enhances the safety of personnel and equipment.

[0066] like Figure 3 As shown, based on the above embodiment, the first wheel body further includes a hub 210, which is connected to the driving member, and the driving member can drive the hub 210 to rotate; wherein, the two opposite ends of the fin portion 220 are an elastic end 222 and a connecting end 221, respectively. The elastic end 222 is close to the wheel gap 250 and can undergo elastic deformation to move closer to or away from the hub 210. The connecting end 221 is away from the wheel gap 250 and is connected to the hub 210.

[0067] In other words, at least the elastic end 222 can undergo elastic deformation to adapt to the surface shape of the metal wall, increasing the contact area between the fin portion 220 and the metal wall, thereby increasing the magnetic attraction force and ensuring that the first wheel can move stably on the metal wall. Obviously, this configuration can support the first wheel through the elastic end 222 and the connecting end 221.

[0068] For example, the connecting end 221 can be detachably connected to the side of the hub 210. For instance, the connecting end 221 and the hub 210 are connected by screws, which facilitates the subsequent replacement of the fin part 220. Optionally, the elastic end 222 and the connecting end 221 are detachably connected. Since the elastic end 222 is in contact with the metal wall surface and is subject to wear, the elastic end 222 and the connecting end 221 are set to be detachably connected, which facilitates the replacement of the elastic end 222 separately and reduces the cost of use.

[0069] For example, the connecting end 221 is made of a high-toughness, high-elasticity material and is configured as L-shaped or plate-shaped.

[0070] For example, the hub 210 should be made of a non-magnetic metal material with good strength and a bending strength of not less than 750MPa to 800MPa to ensure the strength of the hub 210 under cyclic load.

[0071] like Figure 3 As shown, based on the above embodiment, the driving component includes a motor 270, the main shaft of the motor 270 and the hub 210 are coaxially connected, and the motor 270 is configured such that the maximum total torque on the first wheel body is not less than 4 to 5 times its own weight, so as to ensure the overall load-bearing capacity.

[0072] Based on the above embodiment, the end of the fin portion 220 near the wheel gap 250 is configured as a thin-walled structure, and there is a deformation gap between the end of the fin portion 220 near the wheel gap 250 and the hub 210.

[0073] Obviously, since the fin portion 220 is designed as a thin-walled structure, and the end of the fin portion 220 near the wheel gap 250 is suspended, it is possible for the end of the fin portion 220 near the wheel gap 250 to deform and move closer to or further away from the hub 210, thus achieving self-adaptive metal wall surface. It should be noted that the side of the fin portion 220 away from the hub 210 extends to form an arc-shaped surface, thereby enabling all the sides of the fin portion 220 away from the hub 210 to form a wheel surface, that is, to constitute a complete circular cylindrical surface.

[0074] like Figure 3As shown, based on the above embodiment, the fin portion 220 includes a contact module and an elastic module. The contact module is connected to the hub 210 through the elastic module, and there is a gap between the contact module and the hub 210. The elastic module is configured to undergo elastic deformation, wherein the elastic module forms a connecting end 221 and the contact module forms an elastic end 222.

[0075] The elastic module is made of high toughness and high elasticity material and is formed in L-shape or plate shape. Depending on the situation, its Young's modulus is about 0.12GPa to 0.7GPa, which allows the elastic module to generate tough deformation during movement on the metal wall to maintain the smooth movement of the entire device.

[0076] Furthermore, the contact module is rigid as a whole and can be L-shaped or T-shaped. The radial projection of the contact module on the hub 210 can be trapezoidal, rectangular, or involute toothed, etc., without specific limitations. The contact module as a whole can be a single fin or multiple fins. This design can ensure good contact between the tire tread and the metal wall (i.e., the working surface) after the contact module is deformed.

[0077] For example, the hub 210 is fixed to the main shaft of the motor 270 by fixing screws, and both ends of the fixed connecting plate are connected to the hub 210 and the elastic module by fixing screws respectively. One end of the elastic module is fixed to the contact module by a connecting screw.

[0078] like Figure 3 As shown, based on the above embodiment, a permanent magnet 240 is provided on the side of the elastic end 222 facing the hub 210, and a tire surface 230 is formed on the side of the elastic end 222 away from the hub 210.

[0079] For ease of understanding, the side of the elastic end 222 closest to the hub 210 is the inner side, and the side of the elastic end 222 furthest from the hub 210 is the outer side. A permanent magnet 240 is bonded to the inner side of the elastic end 222, and a tire pad is bonded to the outer side of the elastic end 222 to form the tire surface 230. For example, the tire pad is a rubber pad, and magnetic material is disposed within the rubber pad to increase its magnetism. Examples include iron powder and magnetic powder.

[0080] Optionally, an anti-slip structure is provided on the side of the tire pad away from the elastic end 222 to increase the friction between the tire pad and the metal wall surface, thereby reducing the probability of slippage. For example, the anti-slip structure can be an anti-slip pattern or an anti-slip protrusion, etc., and is not specifically limited here, as long as it can achieve the anti-slip effect.

[0081] It should be emphasized that the addition of tire pads is mainly to increase the contact area between the first wheel and the metal wall through their elastic deformation, reduce the distance between the permanent magnet 240 and the metal wall, and correspondingly increase the magnetic attraction between the permanent magnet 240 and the metal wall.

[0082] like Figure 2 and Figure 3 As shown, based on the above embodiment, the number of wheel hubs 210 is one pair, and the pair of wheel hubs 210 are coaxially arranged;

[0083] The drive unit includes a pair of motors 270 and a frame 260. The pair of motors 270 are mounted on the frame 260 and are respectively connected to wheel hubs 210.

[0084] Specifically, the frame 260 has annular flanges on both sides, with multiple circumferential holes on each flange. These holes need to have good alignment to ensure the two motors 270 are collinear, meaning the coaxiality of the two annular flange holes is no less than grade 10. After the two motors 270 are arranged symmetrically as described above, their axes must be collinear to ensure stable movement. Each motor 270 can be individually controlled in terms of its rotation direction and speed, and it has feedback capability, capable of transmitting real-time working status and completed tasks.

[0085] like Figure 1 As shown, according to a second aspect of the present invention, a weld inspection device is provided, the weld inspection device including a magnetic adsorption wheel 200.

[0086] Since the magnetic adsorption wheel 200 has the above-mentioned technical effects, the weld inspection device including the magnetic adsorption wheel 200 should have the same technical effects, which will not be elaborated here.

[0087] Based on the above embodiments, the weld inspection device further includes a frame 300 and an ultrasonic testing component 600. The frame 300 is connected to a magnetic adsorption wheel 200. The ultrasonic testing component 600 is installed on the frame 300 and can detect welds.

[0088] For example, if the frame 300 and the housing 260 are connected, the frame 300 can be moved by controlling the rotation of the magnetic adsorption wheel 200. Clearly, by mounting the ultrasonic testing component 600 to the frame 300 so that the ultrasonic testing component 600 moves with the frame 300, during operation, the frame 300 can be controlled to move along the weld seam, keeping the movement path of the ultrasonic testing component 600 aligned with the weld seam. This allows for the inspection of the weld seam using the ultrasonic testing component 600.

[0089] It should be noted that the ultrasonic testing component 600 is an ultrasonic weld inspection instrument. For those skilled in the art, ultrasonic detection of welds is an existing technology, so the working principle and structure of the ultrasonic testing component 600 will not be described in detail here.

[0090] like Figure 4As shown, based on the above embodiment, the ultrasonic testing component 600 includes a support wheel 610, a damping frame, a shock absorber 620, and an ultrasonic transceiver 630. The support wheel 610 is rotatably connected to the damping frame, and the axis of the support wheel 610 is parallel to the axis of the first wheel body. The damping frame is connected to the frame 300 through the shock absorber 620. The ultrasonic transceiver 630 is mounted on the damping frame.

[0091] In other words, the ultrasonic transceiver 630 is connected to the support wheel 610 through a damping frame. Both the support wheel 610 and the first wheel body are in contact with the metal wall surface, so that the distance between the ultrasonic transceiver 630 and the metal wall surface is basically consistent, which helps to improve the detection accuracy of the weld.

[0092] For example, the ultrasonic transceiver 630 should be a planar oblique ultrasonic transceiver 630, which has the function of receiving and transmitting ultrasonic waves, and the detection angle K is nominally K1, and the ultrasonic frequency is 4-5MHz, so as to ensure that the ultrasonic detection range has sufficient depth and breadth.

[0093] like Figure 4 As shown, based on the above embodiment, the damping frame is equipped with a housing, the ultrasonic transceiver 630 is installed inside the housing, the housing has a wiring hole for receiving the motor 270 wire from the motor 270 of the magnetic adsorption wheel 200 and the ultrasonic transmission line of the ultrasonic transceiver 630, and the rear of the housing has a connection port for connecting external power lines and information transmission lines.

[0094] like Figure 1 As shown, based on the above embodiment, the frame 300 is provided with a control module, a lighting lamp 400 and a camera 500; the lighting lamp 400 is installed in a reserved position on the frame 300 and connected to a dedicated interface of the control module; the camera 500 is connected to the dedicated interface of the control module; the control module is fixed by a reserved buckle on the frame 300.

[0095] The control module is powered by an external power source, which converts the power supply to the magnetic adsorption wheel 200, the lighting lamp 400, the ultrasonic transceiver 630, and the camera 500. The control module is a PLC programmable controller, with driver programs for motor 270, camera 500, and ultrasonic transceiver 630 written in the control module. The entire device is controlled by connecting to a computer via an external information transmission line.

[0096] In addition, the camera 500 can transmit images back to the control interface in real time. The camera 500 can be installed in a position close to the lower part of the frame 300 to facilitate observation of the location of the weld gap.

[0097] like Figure 4As shown, based on the above embodiment, the support wheel 610 includes a second wheel body, which is a magnetic wheel; and the wheel surface of the second wheel body is formed with an annular groove 611, which extends circumferentially along the first wheel body.

[0098] For example, the frame 300 is equipped with a pair of magnetic attraction wheels 200, the frame 300 has an axis of symmetry, and the pair of magnetic attraction wheels 200 are symmetrically arranged about the axis of symmetry.

[0099] Furthermore, by providing a coaxial annular groove 611 on the surface of the second wheel, it is suitable for use on metal walls that are curved or uneven. And since the second wheel is a magnetic wheel, the magnetic attraction between the weld inspection device and the metal wall surface can be increased.

[0100] For example, the magnetic wheel can be the aforementioned magnetic adsorption wheel 200, which can provide sufficient driving force. In other embodiments, the magnetic wheel can also be configured as a non-powered magnetic wheel to reduce the size of the weld inspection device.

[0101] like Figure 4 As shown, based on the above embodiment, the wheel surface of the second wheel body is provided with two sets of raised tire pads, each set of raised tire pads is multiple, and each set of raised tire pads is evenly distributed around the second wheel body, so the above-mentioned annular groove 611 is formed between the two sets of raised tire pads.

[0102] like Figure 5 As shown, based on the above embodiment, the weld inspection device also includes an applicator 100, which is mounted on the frame 300 and can apply coupling agent.

[0103] The applicator 100 is located upstream of the ultrasonic transceiver 630 in the direction of movement, and the ultrasonic transceiver 630 is located on the movement path of the applicator 100.

[0104] For example, the frame 300 has a front end and a rear end in its direction of movement. That is, the applicator 100 is mounted at the front end of the frame 300 and the ultrasonic transceiver 630 is mounted at the rear end of the frame 300. By adjusting the mounting positions of the two, the movement paths of the applicator 100 and the ultrasonic transceiver 630 can be made to overlap.

[0105] Obviously, during operation, the frame 300 can be moved along the weld seam on the metal wall to apply coupling agent to the weld seam via the applicator 100, and then the ultrasonic transceiver 630 can be used to detect the weld seam coated with coupling agent. As is common knowledge in the art, applying coupling agent can improve the accuracy of ultrasonic detection.

[0106] like Figure 5As shown, based on the above embodiment, the applicator 100 includes a coupling agent box and a flexible applicator 130. The coupling agent box stores coupling agent and is connected to the vehicle frame 300. The coupling agent box has a channel that allows the coupling agent in the coupling agent box to flow out. The flexible applicator 130 is installed at the end of the coupling agent box with the channel.

[0107] Obviously, before work begins, the coupling agent is filled into the coupling agent box, and by setting the channel on the side of the coupling agent box facing the weld, that is, at the lower end of the coupling agent box, the coupling agent will flow out from the channel under the action of gravity. Since the flexible application part 130 is installed at one end of the coupling agent box where the channel is set, the flexible application part 130 can move with the frame 300, thus enabling the coupling agent flowing out from the channel to be evenly applied to the weld.

[0108] For example, the coupling agent box includes a coupling agent box cover 110 and a coupling agent box body 120, which are fixed together by connecting screws; the flexible application block is fixed to the bottom of the coupling agent box body 120 by fixing screws.

[0109] It should be noted that during operation, the flexible coating block comes into contact with the metal wall surface.

[0110] like Figure 5 As shown, based on the above embodiment, the flexible application block is made of a flexible absorbent material, such as a sponge. The bottom of the coupling agent box has evenly distributed holes, and one side of the flexible application block has a columnar protrusion 131 corresponding to the evenly distributed holes. During installation, the columnar protrusion 131 passes through the evenly distributed holes at the bottom of the coupling agent box, extends into the interior of the coupling agent box to absorb the coupling agent, and is then applied to the metal wall surface from its other smooth surface. This design provides a more uniform dispensing and application effect, while also saving on the amount of coupling agent used.

[0111] For example, after the flexible coating block is installed, its bottom position should be 5-8mm lower than the lowest point of the magnetic adsorption wheel 200 to ensure good contact with the metal wall surface and facilitate the uniform application of the coupling agent.

[0112] like Figure 4 As shown, based on the above embodiment, the shock absorber 620 includes a pair of first dampers 622 and a pair of second dampers 621. Both of the first dampers 622 are parallel to the first reference plane, and the two opposite ends of the first dampers 622 are respectively hinged to the frame 300 and the damping frame; wherein, the axis of the support wheel 610 is parallel to the first reference plane.

[0113] A pair of second dampers 621 are both parallel to the second reference plane, and the two opposite ends of the second dampers 621 are connected to the frame 300 and the damping frame, respectively; wherein, the second reference plane is perpendicular to the first reference plane.

[0114] The axes of a pair of first dampers 622 intersect with the second reference plane, and the axes of a pair of second dampers 621 intersect with the first reference plane.

[0115] For example, a pair of first dampers 622 are symmetrically and crosswise assembled, and their initial positions and spring coefficients should be consistent. The four initial positions of a pair of second dampers 621 and a pair of first dampers 622 should be adjusted so that their upper and lower ends are in the same horizontal plane to ensure complete contact between the ultrasonic transceiver 630 and the metal wall surface, thereby improving detection accuracy. Optionally, the pair of second dampers 621 are arranged in a figure-eight shape, and the pair of first dampers 622 are arranged in an X shape.
