Description

Technical Field

[0001] This utility model belongs to the field of steel pipe measurement technology, and in particular relates to a magnetic levitation steel pipe measuring device. Background Technology

[0002] In modern industrial systems, steel pipes are critical engineering materials, and their quality directly impacts the safety and lifespan of energy transmission (oil and natural gas pipelines), building structures (building pipes, scaffolding), machinery manufacturing (hydraulic cylinders, drive shafts), and infrastructure (bridges, pile foundations). Wall thickness, as one of the core parameters for measuring steel pipe quality, is crucial in its uniformity and compliance with standards. Insufficient wall thickness significantly weakens the pressure-bearing capacity and structural strength of the steel pipe, easily leading to leaks, deformation, or even catastrophic fractures; uneven wall thickness can cause stress concentration, accelerating localized fatigue failure. Therefore, accurate, efficient, and reliable measurement of steel pipe wall thickness is an indispensable and critical link throughout the entire process of production, quality inspection, and service monitoring.

[0003] With the improvement of industrial automation, online automatic measurement devices for steel pipe wall thickness (such as those based on ultrasonic, laser, and X-ray principles) have been widely used on production lines, improving detection efficiency and coverage. However, existing mainstream automatic measurement systems still generally use traditional mechanical contact or near-contact solutions (such as precision guide rails, rollers, air bearings, and probe supports) in their core displacement positioning and scanning mechanisms. When these solutions meet the measurement requirements of high speed, high precision, and harsh industrial environments, the mechanical contact components such as guide rails, rollers, and bearings inevitably generate friction when operating at high speed, long stroke, heavy load (especially for large-diameter measuring devices), or in dusty environments. Long-term wear causes increased movement clearance and deterioration of straightness / flatness, directly affecting the probe positioning accuracy and repeatability, causing systematic drift in wall thickness measurements, and requiring regular maintenance, leading to equipment downtime and increased operating costs.

[0004] Therefore, this utility model provides a magnetic levitation steel pipe measuring device to solve the problems existing in the prior art. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following solution: This utility model provides a magnetic levitation steel pipe measuring device, comprising:

The X-axis magnetic levitation shell and the X-axis magnetic levitation side plate are arranged opposite each other, and a gap is left between the X-axis magnetic levitation shell and the X-axis magnetic levitation side plate. The X-axis magnetic levitation slider is located in the gap and is slidably connected to the X-axis magnetic levitation side plate. The X-axis magnetic levitation limiting plate is located at both ends of the X-axis magnetic levitation side plate and the X-axis magnetic levitation shell and is fixedly connected to the X-axis magnetic levitation side plate and the X-axis magnetic levitation shell. The X-axis magnetic levitation limiting plate is used to limit the movement of the X-axis magnetic levitation slider.

[0009] Furthermore, the Y-axis magnetic levitation component includes a Y-axis magnetic levitation fixing plate, a Y-axis magnetic levitation outer shell, a Y-axis magnetic levitation side plate, a Y-axis magnetic levitation slider, and a Y-axis magnetic levitation limiting plate. The Y-axis magnetic levitation fixing plate is fixedly connected to one side of the X-axis magnetic levitation slider. The Y-axis magnetic levitation outer shell is fixedly connected to the Y-axis magnetic levitation fixing plate. The Y-axis magnetic levitation outer shell and the Y-axis magnetic levitation side plate are arranged opposite each other, and a gap is left between the Y-axis magnetic levitation outer shell and the Y-axis magnetic levitation side plate. The Y-axis magnetic levitation slider is located within the gap and is slidably connected to the Y-axis magnetic levitation side plate. The Y-axis magnetic levitation limiting plate is located at both ends of the Y-axis magnetic levitation side plate and the Y-axis magnetic levitation outer shell and is fixedly connected to the Y-axis magnetic levitation side plate and the Y-axis magnetic levitation outer shell. The Y-axis magnetic levitation limiting plate is used to limit the Y-axis magnetic levitation slider.

[0010] Furthermore, the Z-axis magnetic levitation component includes a Z-axis magnetic levitation fixing plate, a Z-axis magnetic levitation outer shell, a Z-axis magnetic levitation side plate, a Z-axis magnetic levitation slider, and a Z-axis magnetic levitation limiting plate. The Z-axis magnetic levitation fixing plate is fixedly connected to one side of the Z-axis magnetic levitation slider.

[0012] Compared with existing technologies, the beneficial effects of this utility model patent are as follows: This utility model patent constructs a six-degree-of-freedom spatial positioning of the detection mechanism through a non-contact electromagnetic force field, eliminating sliding friction, elastic deformation, and backlash in the mechanical transmission chain. This frees the probe movement from the inherent error sources of traditional mechanical constraints, resulting in a fundamental leap in motion trajectory accuracy. The physical decoupling structure between the levitation body and the fixed base isolates the transmission path of external vibration to the detection mechanism through mechanical connections, significantly reducing the interference of environmental vibration on the measurement signal and ensuring the positioning stability of the probe under complex industrial conditions. The magnetic levitation displacement mechanism simplifies the complexity and motion inertia of the mechanical system. Traditional multi-axis scanning systems require the superposition of a rotary motor and a linear module to achieve circumferential spiral measurement. Complex gears, couplings, and slides constitute a lengthy force transmission chain, which not only accumulates transmission errors but also causes system response lag due to the large mass of moving parts. The magnetic levitation solution directly drives the detection mechanism through an electromagnetic field, eliminating intermediate conversion devices such as reducers and lead screws, and minimizing the equivalent mass of moving parts. This direct-drive structure endows the detection mechanism with millisecond-level dynamic response capabilities, enabling it to instantly follow the surface undulations or ellipticity changes of a high-speed moving steel pipe, achieving real-time and accurate tracking in motion. Simultaneously, multi-degree-of-freedom electromagnetic coordinated control allows the probe to move flexibly along any spatial path, breaking through the linear motion limitations of traditional mechanical guides. This achieves comprehensive scanning coverage of the entire steel pipe surface without blind spots. The non-contact nature of the magnetic levitation mechanism naturally eliminates dust intrusion and lubrication requirements. The enclosed electromagnetic coil assembly, combined with a protective shell, completely isolates external contaminants, allowing for long-term stable operation in harsh environments such as high-dust and high-temperature hot rolling production lines in steel plants. The suspension gap can be actively controlled to automatically compensate for structural dimensional changes caused by thermal deformation, avoiding motion interference problems caused by differences in thermal expansion coefficients in traditional mechanical systems. This broadens the applicable temperature range of the measuring device. Furthermore, the non-contact motion of the magnetic levitation mechanism completely eliminates sources of mechanical wear; the lifespan of key components depends on electronic components rather than mechanical wear, reducing the need for maintenance throughout the equipment's lifecycle.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] See Figure 1-2 As shown, this embodiment provides a magnetic levitation steel pipe measuring device, including: a placement platform, on which a magnetic levitation displacement mechanism and a placement frame are sequentially arranged, the magnetic levitation displacement mechanism is fixedly connected to a detection mechanism, and a sensor is arranged on one side of the magnetic levitation displacement mechanism for measuring the levitation gap.

[0020] Specifically, the steel pipe is placed on the mounting frame, and the magnetic levitation displacement mechanism is controlled to move it, thereby realizing the multi-dimensional displacement of the detection mechanism. Since it is non-contact, it avoids measurement differences such as wear and tear, and improves measurement accuracy.

[0021] Understandably, traditional measuring devices rely on contact transmission structures such as precision guide rails, ball screws, or air bearings, inevitably introducing mechanical friction and backlash. The nonlinear resistance generated by these physical contacts directly interferes with the accuracy of the motion trajectory of the detection mechanism, causing the measuring probe to drift during high-speed scanning. Magnetic levitation technology, however, constructs a six-degree-of-freedom spatial positioning of the detection mechanism through a non-contact electromagnetic force field, completely eliminating sliding friction, elastic deformation, and backlash in the mechanical transmission chain. This frees the probe from the inherent error sources of traditional mechanical constraints, resulting in a fundamental leap in motion trajectory accuracy. The physical decoupling design between the levitation body and the fixed base isolates the transmission path of external vibrations to the detection mechanism from the structural source, significantly reducing the interference of environmental vibrations on the measurement signal and ensuring the positioning stability of the probe under complex industrial conditions. The magnetic levitation displacement mechanism simplifies the complexity and inertia of the mechanical system. Traditional multi-axis scanning systems require the superposition of a rotary motor and a linear module to achieve circumferential helical measurement. Complex gears, couplings, and slides form a lengthy force transmission chain, not only accumulating transmission errors but also causing system response lag due to the large mass of moving parts. The magnetic levitation solution directly drives the detection mechanism through electromagnetic fields, eliminating intermediate conversion devices such as reducers and lead screws. This minimizes the equivalent mass of moving parts, giving the detection mechanism dynamic response capabilities. It allows it to instantly follow the surface undulations or ellipticity changes of a high-speed moving steel pipe, achieving real-time and precise tracking in motion. Simultaneously, multi-degree-of-freedom electromagnetic coordinated control enables the probe to move flexibly along any spatial path (such as variable-diameter spirals or three-dimensional curved surfaces), breaking through the linear motion limitations of traditional mechanical guides and achieving comprehensive scanning coverage of the entire steel pipe surface without blind spots. In terms of adaptability to extreme environments, the magnetic levitation mechanical structure exhibits revolutionary advantages. Traditional precision guides are extremely sensitive to dust contamination; even tiny particles intruding into the track can cause scratches and jamming. Under high-temperature conditions, lubricating grease failure and metal thermal expansion further degrade motion accuracy and may even cause the mechanism to lock up. The non-contact nature of the magnetic levitation mechanism naturally eliminates the need for dust intrusion and lubrication. The enclosed electromagnetic coil assembly, combined with a protective shell, completely isolates external contaminants, allowing it to operate stably for extended periods in harsh environments such as high-dust and high-temperature hot rolling production lines in steel plants. The active control mechanism of the suspension gap can automatically compensate for structural dimensional changes caused by thermal deformation, avoiding motion interference problems caused by differences in thermal expansion coefficients in traditional mechanical systems, and widening the applicable temperature range of the measuring device. Failures in traditional automatic measuring devices are mostly concentrated in mechanical wear and tear factors such as bearing wear, guide rail damage, and transmission belt aging during high-speed movement, requiring frequent downtime for maintenance. The magnetic levitation mechanism eliminates mechanical wear sources due to its non-contact motion; the lifespan of key components depends on electronic components rather than mechanical wear, reducing the need for maintenance throughout the equipment's lifecycle.

[0022] In some embodiments of this application, the magnetic levitation displacement mechanism includes an electromagnet and an X-axis magnetic levitation component, a Y-axis magnetic levitation component, and a Z-axis magnetic levitation component arranged sequentially from bottom to top. The X-axis magnetic levitation component is fixedly connected to the placement platform, the Y-axis magnetic levitation component is fixedly connected to the X-axis magnetic levitation component, the Z-axis magnetic levitation component is fixedly connected to the Y-axis magnetic levitation component, and the Z-axis magnetic levitation component is fixedly connected to the detection mechanism. The X-axis, Y-axis, and Z-axis magnetic levitation components are used to drive the detection mechanism to move along the X, Y, and Z axes of the placement platform. The electromagnet is located inside the X-axis, Y-axis, and Z-axis magnetic levitation components, respectively.

[0023] Specifically, when displacement is required, the X-axis magnetic levitation component is located at the lowest end. Therefore, the X-axis magnetic levitation component drives the Y-axis magnetic levitation component and the Z-axis magnetic levitation component to achieve displacement in the X-axis direction. The Y-axis displacement component drives the Z-axis displacement component to achieve displacement in the Y-axis direction. Since the detection mechanism is fixedly connected to the Z-axis displacement component, the Z-axis displacement component drives the detection mechanism to achieve the final displacement in the Z-axis direction.

[0024] In some embodiments of this application, the X-axis magnetic levitation component includes an X-axis magnetic levitation shell, an X-axis magnetic levitation side plate, an X-axis magnetic levitation slider, and an X-axis magnetic levitation limiting plate. The X-axis magnetic levitation shell and the X-axis magnetic levitation side plate are arranged opposite each other, and a gap is left between the X-axis magnetic levitation shell and the X-axis magnetic levitation side plate. The X-axis magnetic levitation slider is located in the gap and is slidably connected to the X-axis magnetic levitation side plate. The X-axis magnetic levitation limiting plate is located at both ends of the X-axis magnetic levitation side plate and the X-axis magnetic levitation shell and is fixedly connected to the X-axis magnetic levitation side plate and the X-axis magnetic levitation shell. The X-axis magnetic levitation limiting plate is used to limit the movement of the X-axis magnetic levitation slider.

[0025] In some embodiments of this application, the Y-axis magnetic levitation component includes a Y-axis magnetic levitation fixing plate, a Y-axis magnetic levitation outer shell, a Y-axis magnetic levitation side plate, a Y-axis magnetic levitation slider, and a Y-axis magnetic levitation limiting plate. The Y-axis magnetic levitation fixing plate is fixedly connected to one side of the X-axis magnetic levitation slider. The Y-axis magnetic levitation outer shell is fixedly connected to the Y-axis magnetic levitation fixing plate. The Y-axis magnetic levitation outer shell and the Y-axis magnetic levitation side plate are arranged opposite each other, and a gap is left between the Y-axis magnetic levitation outer shell and the Y-axis magnetic levitation side plate. The Y-axis magnetic levitation slider is located in the gap and is slidably connected to the Y-axis magnetic levitation side plate. The Y-axis magnetic levitation limiting plate is located at both ends of the Y-axis magnetic levitation side plate and the Y-axis magnetic levitation outer shell and is fixedly connected to the Y-axis magnetic levitation side plate and the Y-axis magnetic levitation outer shell. The Y-axis magnetic levitation limiting plate is used to limit the Y-axis magnetic levitation slider.

[0026] In some embodiments of this application, the Z-axis magnetic levitation component includes a Z-axis magnetic levitation fixing plate, a Z-axis magnetic levitation outer shell, a Z-axis magnetic levitation side plate, a Z-axis magnetic levitation slider, and a Z-axis magnetic levitation limiting plate. The Z-axis magnetic levitation fixing plate is fixedly connected to one side of the Z-axis magnetic levitation slider. The Z-axis magnetic levitation outer shell is fixedly connected to the Z-axis magnetic levitation fixing plate. The Z-axis magnetic levitation outer shell and the Z-axis magnetic levitation side plate are arranged opposite each other, and a gap is left between the Z-axis magnetic levitation outer shell and the Z-axis magnetic levitation side plate. The Z-axis magnetic levitation slider is located in the gap and is slidably connected to the Z-axis magnetic levitation side plate. The Z-axis magnetic levitation limiting plate is located at both ends of the Z-axis magnetic levitation side plate and the Z-axis magnetic levitation outer shell and is fixedly connected to the Z-axis magnetic levitation side plate and the Z-axis magnetic levitation outer shell. The Z-axis magnetic levitation limiting plate is used to limit the Z-axis magnetic levitation slider.

[0027] Understandably, each of the X, Y, and Z axes constructs a closed suspension unit (a combination of outer shell, side plate, slider, and limiting plate). The mechanical errors of each axis are strictly limited within the main unit, avoiding the deformation superposition caused by cross-axis force transmission in traditional serial mechanisms. The sliding connection between the slider and the side plate provides radial constraint, while the limiting plate rigidly cuts off axial movement, forming a composite positioning mechanism of "zero friction in the suspension direction + high rigidity in the constraint direction." This retains the frictionless advantage of magnetic levitation while suppressing multi-degree-of-freedom coupled vibration. The direct hard connection between the fixed plate and the slider (such as the Y-axis fixed plate locked to the X-axis slider) establishes a short-path force flow, shortens the load transmission chain, and reduces the structural micro-strain caused by motion inertia. The opposing arrangement of the outer shell and side plate on each axis forms a symmetrical lever arm, offsetting the unilateral bending moment caused by electromagnetic force asymmetry; the bidirectional clamping of the limiting plate at the end constitutes a box-shaped anti-torsional structure, suppressing frame flutter during high-speed reversal. The fixed gap between the outer shell and the side plate is precision machined in one piece to ensure consistent air gap dimensions throughout, preventing assembly stress from altering the magnetic field distribution characteristics. The slider makes full-stroke sliding contact within the gap, correcting air gap offsets caused by thermal deformation in real time. The limiting plate, as the last line of defense, prevents the slider from derailing through mechanical hard contact in the event of control system failure, providing intrinsic safety protection and reducing the risk of collision damage. The X / Y / Z axes achieve three-dimensional stacking through standardized interfaces on the slider fixing plates (e.g., the Y-axis fixing plate is embedded on the X-axis slider side). Pre-loaded gap-eliminating screws on the interface surface eliminate loose connections, maintaining a unified multi-axis motion reference. The wide sliding surface design (non-point contact) between the slider and the side plate disperses the probe's off-center load stress, preventing excessive local pressure from crushing the guide rail surface. The topology optimization of the reinforcing ribs on the suspension component shell specifically improves the bending section modulus. The detachable design of the limiting plate allows for quick replacement of worn sliders without disassembling the entire machine. The separable structure of the side plate and outer shell facilitates cleaning of dust contaminants and restores original motion accuracy.

[0028] In some embodiments of this application, a control unit is also included. The control unit is electrically connected to the detection mechanism and the magnetic levitation displacement mechanism. The control unit is configured to control the magnetic levitation displacement mechanism to achieve displacement. The control unit is also configured to collect detection data from the detection mechanism.

[0029] Specifically, the control unit controls the magnetic levitation displacement mechanism to achieve displacement through the central control device. At the same time, it also collects data such as the steel pipe wall thickness detected by the detection mechanism and transmits it to the central control device for easy control and viewing of detailed data.

[0030] The magnetic levitation steel pipe measuring device in the above embodiments constructs a six-degree-of-freedom spatial positioning of the detection mechanism through a non-contact electromagnetic force field. This eliminates sliding friction, elastic deformation, and backlash in the mechanical transmission chain, freeing the probe from the inherent error sources of traditional mechanical constraints, resulting in a fundamental leap in motion trajectory accuracy. The physical decoupling structure between the levitation body and the fixed base isolates the transmission path of external vibration to the detection mechanism through mechanical connections, significantly reducing the interference of environmental vibration on the measurement signal and ensuring the positioning stability of the probe under complex industrial conditions. The magnetic levitation displacement mechanism simplifies the complexity and motion inertia of the mechanical system. Traditional multi-axis scanning systems require the superposition of a rotary motor and a linear module to achieve circumferential spiral measurement. Complex gears, couplings, and slides constitute a lengthy force transmission chain, which not only accumulates transmission errors but also causes system response lag due to the large mass of moving parts. The magnetic levitation scheme directly drives the detection mechanism through an electromagnetic field, eliminating intermediate conversion devices such as reducers and lead screws, and minimizing the equivalent mass of moving parts. This direct-drive structure endows the detection mechanism with millisecond-level dynamic response capabilities, enabling it to instantly follow the surface undulations or ellipticity changes of a high-speed moving steel pipe, achieving real-time and accurate tracking in motion. Simultaneously, multi-degree-of-freedom electromagnetic coordinated control allows the probe to move flexibly along any spatial path, breaking through the linear motion limitations of traditional mechanical guides. This achieves comprehensive scanning coverage of the entire steel pipe surface without blind spots. The non-contact nature of the magnetic levitation mechanism naturally eliminates dust intrusion and lubrication requirements. The enclosed electromagnetic coil assembly, combined with a protective shell, completely isolates external contaminants, allowing for long-term stable operation in harsh environments such as high-dust and high-temperature hot rolling production lines in steel plants. The suspension gap can be actively controlled to automatically compensate for structural dimensional changes caused by thermal deformation, avoiding motion interference problems caused by differences in thermal expansion coefficients in traditional mechanical systems. This broadens the applicable temperature range of the measuring device. Furthermore, the non-contact motion of the magnetic levitation mechanism completely eliminates sources of mechanical wear; the lifespan of key components depends on electronic components rather than mechanical wear, reducing the need for maintenance throughout the equipment's lifecycle.
