Description

Technical Field

[0001] This invention relates to the field of ultrasonic flaw detection technology, and in particular to an auxiliary mobile device for a handheld ultrasonic flaw detector. Background Technology

[0002] As a core material in high-end equipment fields such as aerospace, rail transportation, and automobile manufacturing, the internal quality of aluminum alloy ingots directly determines the structural safety and service life of downstream products. Therefore, defect detection during the aluminum alloy ingot production process is crucial. Currently, the industry generally uses a semi-continuous casting process for aluminum alloy ingot production. Although this process can achieve efficient mass production, there are unavoidable risks of defects during the casting process: On the one hand, after the high-temperature aluminum liquid is poured, the cooling water comes into direct contact with the ingot surface, creating a drastic temperature difference, which leads to significant thermal stress inside the ingot. This thermal stress can easily cause internal thermal cracks. If these cracks are not detected in time, they will further expand during subsequent plastic processing such as rolling and forging, ultimately leading to product scrap. On the other hand, the aluminum liquid needs to be transported through multiple flow channels before pouring. Oxide scale, impurities on the inner wall of the flow channels, or air entrained during the transportation process can all form defects such as slag entrapment and porosity inside the ingot, seriously affecting the mechanical properties of the aluminum alloy ingot.

[0003] In the field of aluminum alloy casting, ultrasonic testing technology has become a core technical means for identifying defects in aluminum alloy ingots due to its advantages such as large detection depth, high precision, and non-destructive nature to the workpiece. Currently, the mainstream ultrasonic testing equipment is the handheld ultrasonic flaw detector. Its basic operating mode is as follows: the operator holds the flaw detector probe and slowly moves it across the surface of the aluminum alloy ingot according to a preset detection path. The ultrasonic wave reflected signals received by the probe are used to determine whether internal defects exist and their specific location and size.

[0004] However, handheld ultrasonic flaw detectors have the following problems: First, the detection efficiency is low. Operators need to hold the probe for a long time and keep it moving steadily. The detection time for a single large aluminum alloy ingot can usually be several hours, which is difficult to match the production rhythm of an assembly line and results in high labor intensity for personnel. Second, the detection quality is unstable. It is difficult to ensure that the contact pressure between the probe and the surface of the ingot is uniform during manual operation, and the moving speed is easily affected by factors such as the operator's physical strength and fatigue, which makes it easy to miss defects. In particular, for small micro-crack defects, the miss rate of manual detection is as high as 15% or more. Summary of the Invention

[0005] The purpose of this invention is to provide a handheld ultrasonic flaw detector auxiliary mobile device that can improve detection efficiency, reduce labor intensity, and improve detection comprehensiveness and product quality.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A handheld ultrasonic flaw detector auxiliary mobility device is provided, comprising:

[0008] A fixing bracket extends along the length of the solid round ingot and is used to fix it to the solid round ingot;

[0009] A movable support is movably connected to a fixed frame along the length of a solid circular ingot. A probe bracket is fixed to the movable support, and the probe bracket is used to install an ultrasonic probe.

[0010] The driving component is mounted on the movable support and is capable of driving the movable support to move relative to the fixed frame along the length of the solid circular ingot.

[0011] As one possible implementation of the auxiliary mobile device for the aforementioned handheld ultrasonic flaw detector, the fixing frame includes a connecting beam and two sets of fixing components arranged symmetrically. The fixing components are installed on the connecting beam, and each set of fixing components includes multiple fixing parts. The multiple fixing parts are distributed along the length direction of the connecting beam. The two sets of fixing components and the connecting beam enclose a clamping space. The fixing parts can be fixed relative to the outer periphery of the solid round ingot so that the solid round ingot is located within the clamping space.

[0012] As one possible implementation of the auxiliary mobile device for the aforementioned handheld ultrasonic flaw detector, an elastic buffer layer is provided on the side of the fixed part that contacts the solid round ingot.

[0013] As one possible implementation of the auxiliary mobile device for the aforementioned handheld ultrasonic flaw detector, an anti-slip part is provided on the side of the elastic buffer layer away from the fixed part.

[0014] As one possible implementation of the auxiliary mobile device for the aforementioned handheld ultrasonic flaw detector, the connecting beam is a telescopic structure, comprising an inner rod and an outer rod. One end of the inner rod is inserted into the outer rod and slides in cooperation with it. A locking element for locking the inner rod is threaded onto the outer rod.

[0015] As one possible implementation of the auxiliary mobile device for the aforementioned handheld ultrasonic flaw detector, the probe bracket includes a frame and a mounting base. The frame is fixedly connected to the mobile bracket, and the mounting base is installed on the frame. The mounting base is used to install the ultrasonic probe.

[0016] As one possible implementation of the auxiliary mobile device for the aforementioned handheld ultrasonic flaw detector, the probe bracket also includes a telescopic rod, one end of which is connected to the frame and the other end of which is connected to the mounting base. The telescopic rod is telescopic along its own axis.

[0017] As one possible implementation of the auxiliary mobile device for the aforementioned handheld ultrasonic flaw detector, the mounting base is hinged to the telescopic rod via a hinge shaft, and the mounting base can rotate relative to the telescopic rod to make the angle of the ultrasonic probe adjustable.

[0018] As one possible implementation of the auxiliary mobile device for the aforementioned handheld ultrasonic flaw detector, a locking element is provided at the hinge joint between the mounting base and the telescopic rod, which can selectively lock or unlock the mounting base and the telescopic rod.

[0019] As one possible implementation of the auxiliary mobile device for the aforementioned handheld ultrasonic flaw detector, the outer side of the fixed frame is provided with a guide rail extending along its own length direction, the mobile bracket is rotatably connected with a roller, the roller makes rolling contact with the guide rail, the output end of the drive component is connected to the roller for transmission, and the drive component is used to drive the roller to rotate.

[0020] As one possible implementation of the auxiliary mobile device for the aforementioned handheld ultrasonic flaw detector, both ends of the guide rail are provided with limiting blocks, which can abut against the rollers.

[0021] As one possible implementation of the aforementioned handheld ultrasonic flaw detector auxiliary mobility device, the handheld ultrasonic flaw detector auxiliary mobility device further includes:

[0022] The first testing element is set on the probe bracket and is used to detect the contact pressure between the ultrasonic probe and the solid round ingot.

[0023] And / or, a second detection element, which is disposed on the probe bracket, is used to detect the distance between the movable bracket and the limiting block.

[0024] As one possible implementation of the auxiliary mobile device for the aforementioned handheld ultrasonic flaw detector, the outer periphery of the roller is provided with a wear-resistant layer.

[0025] The beneficial effects of this invention are:

[0026] This invention provides a handheld ultrasonic flaw detector auxiliary moving device. Before ultrasonic testing of a solid circular ingot, a coupling agent is first evenly applied to the surface of the ingot. The coupling agent fills the pits on the surface of the solid circular ingot, reducing the attenuation of ultrasonic waves during subsequent testing. Then, a fixing frame is placed on the solid circular ingot and fixed along its length to ensure no displacement deviation during the inspection. Next, the ultrasonic probe is installed on the probe holder, aligning it with the ingot surface to ensure the coupling effect between the ultrasonic probe and the ingot meets the inspection standards. Then, the drive unit is activated, driving the moving bracket to move at a constant speed along the fixing frame. During this process, the ultrasonic probe mounted on the probe holder moves synchronously with the moving bracket, continuously scanning and detecting along the length of the solid circular ingot.

[0027] To achieve comprehensive circumferential inspection of the ingot, the mounting frame is designed to be segmented and fixed along the ingot's circumference. After inspecting a section, the frame is released and rotated to the next inspection area, then re-fixed, repeating the moving inspection process. During inspection, the ultrasonic probe continuously emits ultrasonic waves, acquiring real-time defect signals from the solid circular ingot. The data is synchronously transmitted to the terminal display. Operators only need to monitor the equipment's operating status and inspection data, eliminating the need to manually move the probe, significantly reducing operational intervention.

[0028] Traditional handheld ultrasonic probe testing requires operators to hold the probe for extended periods, moving it slowly along the length of the ingot while maintaining a consistent speed. On average, each meter takes 2-3 minutes to test. This device, however, uses a drive mechanism to move the support frame at a uniform speed, eliminating speed fluctuations associated with manual handling. The speed can be stably controlled at 0.5-1 m / min, reducing the testing time per meter to less than 1 minute and improving efficiency by over 50%. This device enables continuous, uninterrupted testing, avoiding the time-consuming issues of speed fluctuations or breaks caused by fatigue during manual operation. Furthermore, the device provides full-length fixed support for the ultrasonic probe via a mounting frame and probe holder. Operators no longer need to hold the probe; they only need to perform light physical tasks such as device fixation, parameter setting, and status monitoring, significantly reducing labor intensity.

[0029] When manually inspecting ingots with handheld probes, issues such as operator fatigue and visual judgment errors can easily arise, leading to problems like probe trajectory deviation, missed scans, or duplicate scans. This is especially true for longer ingots, where linear movement accuracy is difficult to guarantee, and blind spots can easily appear in circumferential coverage, resulting in a high rate of missed defects. This device's moving bracket moves relative to the fixed frame along the length of the ingot, achieving precise control of the probe's scanning trajectory and avoiding missed or duplicate scans. Combined with segmented circumferential fixation, it enables 360° coverage inspection of the ingot surface without blind spots. Simultaneously, the uniform speed of the drive mechanism avoids signal distortion caused by sudden speed changes during manual operation, ensuring a high detection rate for minute defects. The overall inspection comprehensiveness is improved by more than 60% compared to traditional methods, thus guaranteeing the quality of solid round ingot products. Attached Figure Description

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0039] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0042] like Figure 1-5 As shown, an embodiment of the present invention provides an auxiliary moving device for a handheld ultrasonic flaw detector, including a fixed frame 1, a moving bracket 2, and a driving component 3. The fixed frame 1 extends along the length direction of a solid circular ingot and is used to fix it to the solid circular ingot. The moving bracket 2 is movably connected to the fixed frame 1 along the length direction of the solid circular ingot. A probe bracket 4 is fixed to the moving bracket 2, and the probe bracket 4 is used to install an ultrasonic probe 5. The driving component 3 is installed on the moving bracket 2 and can drive the moving bracket 2 to move relative to the fixed frame 1 along the length direction of the solid circular ingot. Specifically, the driving component 3 is a drive motor.

[0043] Before ultrasonic testing of the solid circular ingot, a coupling agent is first evenly applied to the surface of the ingot. This agent fills the pits on the surface, reducing ultrasonic attenuation during subsequent testing. Then, the mounting bracket 1 is placed on the solid circular ingot and fixed along its length to ensure no displacement deviation during testing. Next, the ultrasonic probe 5 is installed on the probe holder 4, aligning it with the ingot surface to ensure the coupling effect between the probe 5 and the ingot meets the testing standards. Then, the drive unit 3 is activated, driving the moving bracket 2 to move uniformly along the mounting bracket 1. During this process, the ultrasonic probe 5, mounted on the probe holder 4, moves synchronously with the moving bracket 2, continuously scanning along the length of the solid circular ingot.

[0044] To achieve comprehensive circumferential inspection of the ingot, the fixing frame 1 is designed to be segmented and fixed along the circumference of the ingot. After completing the inspection of a section, the fixing frame 1 is released and rotated to the next inspection area, and then re-fixed, repeating the above moving inspection process. During the inspection, the ultrasonic probe 5 continuously emits ultrasonic waves to collect the internal defect signals of the solid circular ingot in real time. The data is synchronously transmitted to the terminal display. The operator only needs to monitor the equipment's operating status and inspection data, without having to hold the probe and follow its movement, greatly reducing the intensity of operational intervention.

[0045] Traditional handheld ultrasonic probe testing requires operators to hold the probe for extended periods, moving it slowly along the length of the ingot while maintaining a consistent speed. On average, each meter takes 2-3 minutes to test. This device, however, uses a drive unit 3 to move the moving support 2 at a uniform speed, eliminating speed fluctuations associated with manual handling. The moving speed can be stably controlled at 0.5-1 m / min, reducing the testing time per meter to less than 1 minute and improving efficiency by over 50%. This device enables continuous, uninterrupted testing, avoiding the time-consuming issues of speed fluctuations or breaks caused by fatigue during manual operation. Furthermore, the device uses a fixed frame 1 and a probe support 4 to provide full-length fixed support for the ultrasonic probe 5. Operators no longer need to hold the probe; they only need to perform light physical tasks such as device fixation, parameter setting, and status monitoring, significantly reducing labor intensity.

[0046] When manually inspecting ingots with handheld probes, issues such as operator fatigue and visual judgment errors can easily occur, leading to problems like probe trajectory deviation, missed scans, or duplicate scans. This is especially true for longer ingots, where linear movement accuracy is difficult to guarantee, and blind spots can easily appear in circumferential coverage, resulting in a high rate of missed defects. This device addresses this by moving the support 2 along the length of the ingot relative to the fixed frame 1, achieving precise control of the probe scanning trajectory and preventing missed or duplicate scans. Combined with segmented circumferential fixing, it enables 360° coverage inspection of the ingot surface without blind spots. Simultaneously, the uniform speed of the drive unit 3 avoids signal distortion caused by sudden speed changes during manual operation, ensuring a high detection rate for minute defects. The overall inspection comprehensiveness is improved by more than 60% compared to traditional methods, thus guaranteeing the quality of solid round ingot products.

[0047] Furthermore, such as Figure 1 and Figure 3 As shown, the fixing frame 1 includes a connecting beam 11 and two symmetrically arranged sets of fixing components. The fixing components are installed on the connecting beam 11. Each set of fixing components includes multiple fixing parts 12, which are distributed along the length of the connecting beam 11. The two sets of fixing components and the connecting beam 11 enclose a clamping space. The fixing parts 12 can be fixed relative to the outer periphery of the solid round ingot so that the solid round ingot is located within the clamping space. Specifically, the fixing parts 12 are rubber pressure plates.

[0048] Each set of fixing components has multiple fixing parts 12 along the length of the connecting beam 11, forming multiple points of uniform force distribution, avoiding the ingot from shifting due to its own weight or vibration, and improving the fixing stability.

[0049] The rubber material is soft and does not generate rigid friction when in contact with the outer circumference of the solid round ingot. This avoids surface defects such as scratches and indentations caused by metal fixing parts 12, ensuring the surface quality of the ingot in subsequent processing. In addition, the rubber has good elasticity and anti-slip properties, which can increase the friction with the outer circumference of the ingot. Even if the ingot is subjected to external force or vibration, it can reduce relative slippage and ensure that the ingot is stably held in the clamping space. The outer circumference of the solid round ingot may have slight dimensional deviations or roundness errors. The elasticity of the rubber pressure plate can achieve slight deformation, which can closely fit the outer contour of the ingot, allowing each fixing part 12 to be evenly stressed, avoiding ingot deformation or loosening caused by excessive local stress.

[0050] Furthermore, an elastic buffer layer is provided on the side of the fixing part 12 that contacts the solid circular ingot. Specifically, the elastic buffer layer can be made of silicone, polyurethane, or nitrile rubber, etc. The elastic material can transform the rigid contact between the fixing part 12 and the ingot into a flexible contact, greatly reducing the impact force and preventing indentations, scratches, or metal fatigue cracks from appearing on the surface of the ingot. It is especially suitable for precision ingots with high surface finish requirements.

[0051] Furthermore, an anti-slip portion is provided on the side of the elastic buffer layer away from the fixing part 12. Specifically, the anti-slip portion is an anti-slip texture or anti-slip protrusion, etc. By increasing the roughness of the contact surface, the anti-slip portion increases the coefficient of friction with the outer periphery of the ingot, further improving the fixing stability.

[0052] Furthermore, such as Figure 4 As shown, the outer side of the fixed frame 1 is provided with a guide rail 6 extending along its own length direction. The movable bracket 2 is rotatably connected with a roller 7. The roller 7 rolls in contact with the guide rail 6. The output end of the drive component 3 is connected to the roller 7 for transmission. The drive component 3 is used to drive the roller 7 to rotate.

[0053] The roller 7 and the guide rail 6 have rolling friction, and the coefficient of friction is much smaller than that of sliding friction, which reduces the moving resistance. The drive component 3 does not need to overcome a large amount of sliding resistance, which can reduce energy consumption and improve drive efficiency; at the same time, it makes the movement of the moving bracket 2 smoother and avoids jamming.

[0054] The guide rail 6 adopts a double parallel rail design, and the rollers 7 are symmetrically distributed. The guide rail 6 extends along the length of the fixed frame 1, providing a clear guiding path for the rollers 7. It can strictly limit the movement direction of the moving support 2, avoid deviation, improve movement accuracy, and ensure the reliability of the test data.

[0055] Furthermore, both ends of the guide rail 6 are provided with limit blocks, which can abut against the roller 7.

[0056] The limit block directly abuts against the roller 7, which can limit the movement range of the movable support 2 on the fixed frame 1, and prevent the movable support 2 from falling off the guide rail 6 due to excessive movement, thus ensuring the safety of the equipment.

[0057] Optionally, a rubber pad is provided on the side of the limiting block facing the roller 7 to attenuate the impact force of the collision, thereby protecting the roller bearing, guide rail 6 and transmission components of the drive unit 3, and reducing maintenance costs.

[0058] Furthermore, the connecting beam 11 is a telescopic structure, comprising an inner rod and an outer rod. One end of the inner rod is inserted into the outer rod and slides within it. The outer rod is threaded with a locking element for locking the inner rod. Specifically, the locking element is a bolt.

[0059] The sliding of the inner rod relative to the outer rod can change the total length of the connecting beam 11, thereby adjusting the spacing between the two sets of fixing components. This allows it to accommodate solid round ingots of different lengths without the need to replace the dedicated fixing frame 1, reducing equipment investment costs and expanding application scenarios. Simply loosen the locking parts to slide the inner rod to adjust its length, and tighten the locking parts to fix it in place. The operation is simple, requiring no complicated tools, and can quickly switch between clamping ingots of different specifications, improving work efficiency. When the equipment is idle or being transported, the length of the connecting beam 11 can be shortened to reduce space occupation and improve the convenience of storage and transportation.

[0060] Furthermore, such as Figure 5 As shown, the probe bracket 4 includes a frame and a mounting base. The frame is fixedly connected to the movable bracket 2, and the mounting base is installed on the frame. The mounting base is used to install the ultrasonic probe 5.

[0061] The frame and the movable bracket 2 are rigidly connected, providing a stable support base for the mounting base. The mounting base is specifically designed to meet the installation requirements of the ultrasonic probe 5, and can be fixed to the probe by bolts, clips, etc., to prevent the probe from loosening or shifting during the test and to ensure stable detection signal. The mounting base can be designed with a custom fixing structure according to the size and mounting hole position of the ultrasonic probe 5. There is no need to modify the frame; only the corresponding mounting base needs to be replaced to adapt to different models and specifications of ultrasonic probes 5, improving the versatility of the probe bracket 4 and reducing equipment modification costs.

[0062] Furthermore, the probe bracket 4 also includes a telescopic rod, one end of which is connected to the frame body, and the other end of which is connected to the mounting base. The telescopic rod is extendable and retractable along its own axis. Specifically, the telescopic rod is a pneumatic push rod.

[0063] The telescopic rod can extend and retract axially, directly changing the distance between the mounting base and the frame, and the surface of the ingot. This also changes the distance between the ultrasonic probe 5 and the ingot surface. It allows for quick adjustment of the probe to the optimal detection position based on the diameter and required detection depth of the solid round ingot, preventing collisions due to excessive proximity or signal interference from excessive distance. For ingots with slight surface deviations, the probe position can be fine-tuned using the telescopic rod. This ensures the probe fits snugly against the ingot's detection requirements, covering more detection points and reducing blind spots caused by fixed positions, thus guaranteeing comprehensive detection.

[0064] Furthermore, the mounting base is hinged to the telescopic rod via a hinge shaft, allowing the mounting base to rotate relative to the telescopic rod to make the ultrasonic probe angle adjustable.

[0065] By rotating the mounting base to adjust the probe angle, the detection area can be covered in different directions on the ingot surface. This addresses minor surface irregularities and roundness deviations, reducing blind spots that cannot be covered by a fixed angle and improving the defect detection rate. The solid round ingot has an arc-shaped outer circumference, and the adjustable probe angle ensures that the ultrasonic wave emission direction is perpendicular to the ingot surface. This avoids signal attenuation or reflection distortion caused by angular deviations, ensuring effective ultrasonic wave penetration and improving the accuracy of defect detection.

[0066] Different ultrasonic incident angles may be required for different testing standards and defect types (such as internal cracks, inclusions, etc.). The adjustable angle design allows for flexible switching of the testing angle without the need to replace a dedicated probe or bracket, adapting to diverse testing scenarios, reducing equipment adaptation costs, and improving equipment versatility.

[0067] Furthermore, a locking element is provided at the hinge joint between the mounting base and the telescopic rod, which can selectively lock or unlock the mounting base and the telescopic rod. Specifically, the locking element adopts a combination structure of bolts and friction plates. The bolts pass through the hinge shaft holes of the telescopic rod and the mounting base. By tightening the bolts, the friction plates are squeezed, and the angle of the mounting base is locked by friction. Loosening the bolts unlocks the rotation.

[0068] After the angle is adjusted to the correct position, the locking component can fix the relative position of the mounting base and the telescopic rod, which can prevent the probe angle from shifting due to equipment vibration or external force during the testing process, ensuring the uniformity of the angle of the same batch of ingots or the same testing area, improving the consistency and reliability of the test data, and ensuring the accuracy of the test.

[0069] Continue as Figure 5 As shown, the ultrasonic probe 5 is connected to the data acquisition unit via the probe data cable 8. The data acquisition unit and the screen are integrated into one unit, reducing the redundancy of equipment cables and making it convenient for operators to carry and move. It is especially suitable for the use of handheld ultrasonic flaw detectors, improving the flexibility of on-site operation.

[0070] The screen displays waveform curves in real time, directly reflecting the signal state at the moment of detection, avoiding data transmission delays or distortion during storage. Operators can judge internal defects in the ingot by observing the waveform curves displayed on the screen in real time, without waiting for data export. They can immediately observe the ultrasonic reflection signal and quickly determine whether there are defects such as cracks or inclusions inside the ingot by observing abnormal fluctuations in the waveform (such as peak shifts or increased noise), shortening the detection and judgment cycle. Operators can also analyze the waveform simultaneously with the on-site detection scenario (such as probe position and pressure status), reducing misjudgments caused by data lag and improving the accuracy of defect judgment.

[0071] Furthermore, the auxiliary mobile device for the handheld ultrasonic flaw detector also includes a first detection element, which is mounted on the probe bracket 4. The first detection element is used to detect the contact pressure between the ultrasonic probe 5 and the solid round ingot. Specifically, the first detection element is a pressure sensor.

[0072] Furthermore, the auxiliary moving device of the handheld ultrasonic flaw detector also includes a second detection element, which is mounted on the probe bracket 4 and is used to detect the distance between the moving bracket 2 and the limiting block. Specifically, the second detection element is a distance sensor.

[0073] The auxiliary mobile device for the handheld ultrasonic flaw detector also includes a controller, and the pressure sensor, distance sensor, and drive unit are all electrically connected to the controller. The pressure sensor detects the contact pressure between the ultrasonic probe 5 and the solid round ingot. If the contact pressure exceeds a preset range, the pressure sensor transmits a signal to the controller, which then stops the drive unit 3 from operating. This avoids signal attenuation, distortion, or missed defects caused by abnormal pressure, while also preventing excessive probe wear and scratches on the ingot surface, ensuring stable and reliable test data.

[0074] The distance sensor detects the distance between the moving support 2 and the limit block. If the distance is less than a preset value, the distance sensor transmits a signal to the controller, which then controls the drive component 3 to decelerate. This prevents the moving support 2 from impacting the limit block at high speed, reduces wear and tear on the roller 7, guide rail 6, and limit block from rigid impacts, and prevents the ingot from shifting due to impact, ensuring the structural safety of the equipment and the workpiece.

[0075] It should be noted that the controller can be a centralized or distributed control board. For example, the controller can be a single microcontroller or a combination of multiple distributed microcontrollers. The microcontroller can run a control program to control each component to achieve its function.

[0076] Furthermore, a wear-resistant layer is provided on the outer periphery of the roller 7. Specifically, the wear-resistant layer is a polyurethane coating layer, which is attached to the outer periphery of the roller 7 by casting or vulcanization process.

[0077] The elastic wear-resistant layer can absorb impact energy, avoid rigid friction between roller 7 and guide rail 6, reduce wear on guide rail 6, extend the service life of roller 7, and reduce maintenance costs.

[0078] Optionally, the movable support 2 is provided with a handle. The handle has an arc-shaped structure, which makes it convenient for the operator to hold the movable support 2 and manually push the movable support 2 to move when the drive component 3 fails.

[0079] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
