Description
Technical Field
[0001] This invention relates to the field of magnetic levitation train track construction technology, specifically to an integrated installation device and method for magnetic levitation stator core and long stator coil. Background Technology
[0002] As a core representative of my country's high-end rail transit equipment, high-speed maglev trains have become a key development direction for future intercity and urban rail transit due to their unique advantages such as high operating speed, high driving stability, low noise pollution, and low mechanical wear. The long stator coil, as a core component of the high-speed maglev train traction system, directly determines the power conversion efficiency, operational stability, and train driving safety of the traction system through its construction quality.
[0003] From the perspective of existing construction technology, the stator core is in an alternating magnetic field working environment for a long time. During operation, it will continuously generate energy losses such as hysteresis loss and eddy current loss, as well as mechanical wear and insulation aging. According to industry maintenance standards, it must be replaced regularly. The conventional process for replacing the stator core is as follows: first, the original old long stator coil is manually removed. After the core is disassembled, replaced and fixed, the bending, rolling, laying, embedding and shaping of the new coil are carried out again. The traditional construction methods currently widely used in the industry have several unavoidable technical defects that severely restrict construction efficiency and quality control: First, the secondary shaping and repositioning after coil embedding relies entirely on manual adjustment by workers using rubber mallets. The force applied is entirely based on experience; excessive force can easily puncture the cable insulation layer and cause deformation of the inner lining, while insufficient force results in insecure coil embedding and poor fit with the iron core grooves, failing to meet construction precision requirements and leading to a low shaping pass rate. Second, coil loading and lifting rely entirely on manual handling, lacking dedicated loading and lifting mechanisms. During the dragging of long stator coils, they are prone to hard friction with the track plate and iron core grooves, further increasing the risk of insulation layer scratching and damage. Third, traditional simple mobile tooling lacks a force balance monitoring structure, easily leading to uneven pressure on the rollers and one-sided imbalance during movement, causing coil misalignment and further increasing rework rates. Therefore, it does not meet current needs. Therefore, to address the issue of not meeting existing requirements, we have proposed an integrated installation device and usage method for magnetic levitation stator core and long stator coil. Summary of the Invention
[0004] The purpose of this invention is to provide an integrated installation device and method for magnetic levitation stator cores and long stator coils. By replacing manual hammering with a set hammering drive component, flexible and automated shaping and embedding are achieved, allowing for pre-embedding of the coils and cores, significantly improving construction accuracy and pass rate. Equipped with a dedicated feeding and electric lifting mechanism for synchronous lifting into place, the entire process is completed without manual handling or dragging, eliminating hard friction damage to the insulation layer. The addition of a real-time pressure monitoring and automatic leveling structure, combined with an infrared laser device, achieves precise centering and positioning, greatly improving installation efficiency and accuracy, reducing disassembly and assembly losses, and solving the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated installation device and method for magnetic levitation stator core and long stator coil, comprising a connecting bracket, one end of which is fitted with an inverted assembly via fixing bolts, and the other end of which is fitted with a side connecting bracket via fixing bolts. Traveling rollers are installed on both sides of the connecting bracket, a moving assembly is installed on the upper surface of the connecting bracket, and a pneumatic pump is installed on the moving assembly. A feeding assembly is connected to the side of the inverted assembly, and a striking drive assembly is provided on the feeding assembly.
[0006] Preferably, the inverted assembly includes an inverted bracket, an inverted frame, a lifting cylinder, a support rod, a load-bearing platform, and a lifting platform. A transition platform is provided on one side of the inverted bracket, and the inverted frame is provided on the side of the transition platform away from the transition platform. A support rod is fixed to the bottom of the inverted bracket, and a load-bearing platform is movably mounted on the support rod. The load-bearing platform can slide on the support rod to make fine adjustments to the lifting cylinder. The lifting cylinder is mounted on the load-bearing platform, and a lifting platform is provided on the top of the lifting cylinder. An infrared laser device is provided on the lifting platform.
[0007] Preferably, both the inverted bracket and the side connecting frame are equipped with side rollers. The connecting bracket, inverted bracket, inverted frame and side connecting frame are all made of high-strength hollow aluminum alloy and the surface is anodized for corrosion protection. A hydraulic rod connects the bearing platform and the inverted bracket.
[0008] Preferably, the moving component includes a first motor, a threaded rod, a moving platform, a mounting plate, a moving block, a limiting plate, and a sliding rod. The output end of the first motor is connected to the threaded rod, and the end of the threaded rod away from the first motor is rotatably mounted on the mounting plate. The first motor is mounted on the outside of the mounting plate and is a reversible motor. A sliding rod is provided on the side corresponding to the threaded rod, and the sliding rod is parallel to the threaded rod. Moving blocks are movably mounted on both the sliding rod and the threaded rod. The moving blocks are fixed on both sides of the moving platform. A limiting plate is provided on the moving platform, and a pneumatic pump is provided on the moving platform and is limited by the limiting plate.
[0009] Preferably, the feeding assembly includes a moving wheel, a mounting frame, an adjusting component, a support frame, a roller, and a hook. The inner side of the mounting frame is provided with a roller, which is used to feed the long stator coil without manual feeding, saving manpower. The upper surface of the mounting frame is equipped with adjusting components on both sides, and the right side of the adjusting component is provided with a mounting frame. The hammering drive component is installed on the mounting frame, and the adjusting component is used to straighten and bend the long stator coil. A moving wheel is installed on one lower surface of the mounting frame, and a hook is installed on the other lower surface. The feeding assembly is connected to the inverted frame through the hook.
[0010] Preferably, the adjustment assembly includes a support plate, a hydraulic rod, a movable plate, and a guide groove. The support plate is fixed on the mounting frame, and a hydraulic rod is installed on the outer side of the support plate. The extended end of the hydraulic rod passes through the support plate and connects to the movable plate. The movable plate is provided with multiple guide grooves, which are used to guide the long stator coil. By passing the long stator coil through the guide grooves in sequence, the long stator coil can be bent.
[0011] Preferably, the striking drive assembly includes a second motor, a disc, a first mounting rod, a limiting block, a connecting rod, a second mounting rod, a connector, a sliding column, and a striking assembly. The second motor is mounted on a bearing plate, which is fixed to a support plate. The output end of the second motor is mounted on the disc. The top of the disc is provided with a first mounting rod, which is connected to the second mounting rod via a connecting rod. A limiting block is provided on the first mounting rod to prevent the connecting rod from slipping off. The second mounting rod is fixed to the connector, which is mounted on the sliding column.

[0012] Preferably, the striking assembly includes a sleeve, a spring, a sleeve rod, and a striking seat. The spring is installed inside the sleeve, and the bottom of the spring is fixed to the sleeve rod. The bottom of the sleeve rod is fixed to the striking seat. When the stator core is clamped onto the long stator coil, the operator moves the assembled stator core clamp and long stator coil to directly below the striking seat, starts the second motor to drive the disc to rotate. During one rotation of the disc, the sliding column is pressed down and lifted up. The sliding column drives the striking seat to move synchronously, realizing automatic striking and embedding the long stator coil into the stator core.
[0013] Preferably, each roller shaft of the traveling roller is equipped with a pressure-sensitive resistor monitoring module, and the sensing end of the pressure-sensitive resistor is in direct and close contact with the surface of the magnetic levitation track to collect the pressure values of the rollers on both sides of the connecting bracket in real time.
[0014] The method for using the integrated mounting device for magnetic levitation stator core and long stator coil includes the following steps: Step 1: Move the connecting bracket to the construction site, install the inverted component on one end of the connecting bracket with fixing bolts, install the side connecting bracket on the other end of the connecting bracket with fixing bolts, install the air pressure pump on the moving platform, and limit it with the limiting plate; Step 2: Connect the feeding component to the inverted frame using hooks, preset the pressure difference warning threshold, and collect the pressure values of the rollers on both sides of the connecting bracket in real time through the pressure-sensitive resistor monitoring module. When the pressure difference on both sides exceeds the warning threshold, start the first motor to make the threaded rod rotate and thus drive the moving platform to move, adjust the position of the air pump, and thus adjust the pressure on both sides of the connecting bracket. When the pressure values on both sides return to within the warning threshold, the first motor stops working. Step 3: Based on the bending length of the long stator coil, start the hydraulic rod to adjust the position of the moving plate. Stop after adjusting to the appropriate position. Then, bend the long stator coil by passing it through the guide groove. After bending, clamp the stator core onto the long stator coil. Step 4: When the stator core is secured to the long stator coil, the operator moves the assembled stator core and long stator coil to directly below the striking base, starts the second motor to drive the disc to rotate. During the rotation of the disc, the sliding column is pressed down and lifted up. The sliding column drives the striking base to move synchronously, realizing automatic striking and embedding the long stator coil into the stator core. Step 5: After the installation is completed, move the long stator coil and stator core to the lifting platform. Use the infrared laser device on the lifting platform to locate the installation position of the long stator coil and stator core. If the actual installation position does not match the position of the long stator coil and stator core, activate the hydraulic rod to move the bearing platform along the support rod to adjust the position of the long stator coil and stator core. When the adjustment is consistent with the actual installation position, activate the lifting cylinder to move the long stator coil and stator core to the construction site for installation.
[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up a hammering drive component and a buffer hammering component, and by using a second motor to drive the disc, connecting rod, and sliding column in a coordinated manner, achieves automated and constant-force hammering and embedding operations, eliminating the need for manual hammering. The hammering component has a built-in spring buffer structure, which can effectively buffer the impact force of hammering, avoiding excessive rigid hammering force that could break through the coil insulation layer and cause deformation of the inner lining. At the same time, the hammering force is uniform and controllable, ensuring that the coil and the iron core teeth are tightly fitted and firmly embedded without loosening. This completely solves the industry pain point of uneven hammering force, and the construction accuracy is controllable throughout the process. The coil shaping and embedding qualification rate is greatly improved, fully meeting the construction accuracy requirements of high-speed magnetic levitation long stator coils, and eliminating construction waste and rework problems caused by human operation errors. 2. This invention utilizes a roller-type feeding assembly and a lifting cylinder electric lifting mechanism. The feeding assembly uses rollers to automatically and uniformly feed long stator coils, eliminating the need for manual handling and dragging of coil cables. This fundamentally avoids hard friction between the coil and the track plate and iron core grooves. The lifting cylinder, as a dedicated electric lifting component, enables the coil to be lifted electrically and smoothly without manual lifting. The lifting speed is infinitely adjustable and the height is precisely controllable. There is no dragging, bumping, or hard friction throughout the process, completely eliminating mechanical damage to the outer and inner layers of the coil caused by manual handling and dragging. This comprehensively protects the integrity of the coil insulation layer, reducing construction losses and subsequent maintenance costs. 3. This invention, by equipping the rotating shaft of the traveling rollers with a high-precision piezoresistive monitoring module, combined with a movable and adjustable moving component and a pneumatic pump counterweight structure, achieves closed-loop control with real-time pressure monitoring and automatic leveling in case of imbalance. The piezoresistive sensor collects the pressure values of the two rollers in real time. When the pressure difference exceeds the warning threshold, the first motor is automatically started to drive the threaded rod to rotate, thereby displacing the moving platform and the pneumatic pump. This quickly adjusts the overall center of gravity of the fixture, balances the pressure of the two rollers, and completely avoids problems such as one-sided weight imbalance, skewed movement, and misaligned laying. It ensures accurate positioning and balanced force throughout the movement of the fixture and the laying of the coil, fundamentally solving the construction deviation caused by fixture offset, significantly reducing the construction rework rate, and improving the overall construction efficiency and quality stability.

Detailed Implementation
[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] To address the issue of secondary reshaping and resetting after coil embedding in existing technology, which relies entirely on manual adjustment using rubber mallets by construction workers, the required precision cannot be met, resulting in a low reshaping pass rate. Furthermore, the lack of a dedicated feeding and lifting mechanism exacerbates the risk of insulation layer scratches and damage. During movement, uneven pressure on the rollers and one-sided imbalances can easily occur. Please refer to [link / reference needed]. Figures 1-7 This embodiment provides the following technical solution: An integrated installation device for magnetic levitation stator core and long stator coil includes a connecting bracket 1. One end of the connecting bracket 1 is fitted with an inverted assembly 2 by fixing bolts, and the other end is fitted with a side connecting bracket 3 by fixing bolts. Traveling rollers 7 are installed on both sides of the connecting bracket 1. A moving assembly 4 is installed on the upper surface of the connecting bracket 1. An air pressure pump 6 is installed on the moving assembly 4. A feeding assembly 5 is connected to the side of the inverted assembly 2. A knocking drive assembly 8 is provided on the feeding assembly 5.
[0020] The inverted assembly 2 includes an inverted bracket 21, an inverted frame 23, a lifting cylinder 24, a support rod 25, a bearing platform 26, and a lifting platform 27. A transition platform 29 is provided on one side of the inverted bracket 21, and the inverted frame 23 is provided on the side of the transition platform 29 away from the transition platform. The support rod 25 is fixed to the bottom of the inverted bracket 21, and the bearing platform 26 is movably mounted on the support rod 25. The bearing platform 26 can slide on the support rod 25 to fine-tune the lifting cylinder 24. The lifting cylinder 24 is mounted on the bearing platform 26, and the lifting platform 27 is provided on the top of the lifting cylinder 24. An infrared laser device is provided on the lifting platform 27. The lifting cylinder 24 is used to achieve electric and stable lifting of the long stator coil. The lifting cylinder 24 is equipped with an independent... The system includes a hydraulic pump station, a pressure regulating valve, and a stroke controller. The pressure regulating valve precisely controls the lifting speed, which is steplessly adjustable to prevent sudden stress changes that could cause damage to the long stator coil during rapid lifting. The stroke controller precisely controls the lifting height, ensuring that the long stator coil is lifted to the corresponding height of the iron core slots without excessive height or height deviation. The lifting platform 27 increases the force-bearing area during the lifting of the long stator coil, dispersing local pressure on the cable and preventing single-point crushing damage. This achieves a completely damage-free lifting of the long stator coil from the ground to the construction height, fundamentally solving the technical problem of damage to the insulation surface caused by manual hammering. The transition platform 29 is used to transition the long stator coil to the stator core, preventing accidental bending and damage to the long stator coil and stator core when moving to the lifting platform.
[0021] Both the inverted bracket 21 and the side connecting frame 3 are equipped with side rollers 22. The connecting bracket 1, the inverted bracket 21, the inverted frame 23 and the side connecting frame 3 are all made of 6061-T6 high-strength hollow aluminum alloy with anodized anti-corrosion treatment. They are corrosion-resistant, wear-resistant and deformation-resistant, suitable for the harsh outdoor environment of track construction. The single-sided load capacity is ≥60kg and the standard section weight is ≤80kg. The lightweight design facilitates manual assembly, disassembly and transportation. The bearing platform 26 and the inverted bracket 21 are connected by a hydraulic rod 28.
[0022] The moving component 4 includes a first motor 41, a threaded rod 42, a moving platform 43, a mounting plate 44, a moving block 45, a limiting plate 46, and a sliding rod 47. The output end of the first motor 41 is connected to the threaded rod 42. The end of the threaded rod 42 away from the first motor 41 is rotatably mounted on the mounting plate 44. The first motor 41 is mounted on the outside of the mounting plate 44. The first motor 41 is a forward and reverse motor. A sliding rod 47 is provided on the side corresponding to the threaded rod 42. The sliding rod 47 is parallel to the threaded rod 42. Moving blocks 45 are movably mounted on both the sliding rod 47 and the threaded rod 42. The moving blocks 45 are fixed on both sides of the moving platform 43. A limiting plate 46 is provided on the moving platform 43. The air pump 6 is mounted on the moving platform 43 and is limited by the limiting plate 46 to prevent the air pump 6 from falling off the moving platform 43 and affecting normal use.
[0023] The feeding assembly 5 includes a moving wheel 51, a mounting frame 52, an adjusting assembly 53, a support frame 54, a roller 55, and a hook 56. The inner side of the mounting frame 52 is provided with a roller 55, which is used to feed long stator coils without manual feeding, saving manpower. The upper surface of the mounting frame 52 is equipped with adjusting assemblies 53 on both sides. The right side of the adjusting assembly 53 is provided with the mounting frame 52. The hammering drive assembly 8 is installed on the mounting frame 52. The adjusting assembly 53 is used to arrange and bend the long stator coils. The lower surface of one side of the mounting frame 52 is equipped with a moving wheel 51, and the lower surface of the other side is equipped with a hook 56. The feeding assembly 5 is connected to the inverted frame 23 through the hook 56.
[0024] The adjustment assembly 53 includes a support plate 531, a hydraulic rod 532, a movable plate 533, and a guide groove 534. The support plate 531 is fixed on the mounting frame 52. The hydraulic rod 532 is installed on the outer side of the support plate 531. The extended end of the hydraulic rod 532 passes through the support plate 531 and connects to the movable plate 533. The movable plate 533 is provided with multiple guide grooves 534. The guide grooves 534 are used to guide the long stator coil to prevent the long stator coil from getting tangled. At the same time, the long stator coil can be bent by passing through the guide grooves 534 one by one without manual bending. After bending, the stator core is clamped on the long stator coil. Then, the stator core is hammered into the stator core by the hammering drive assembly 8. According to the bending length of the long stator coil, the hydraulic rod 532 is activated to adjust the position of the movable plate 533. The position is stopped after adjusting to the appropriate position.
[0025] The striking drive assembly 8 includes a second motor 81, a disc 82, a first mounting rod 83, a limiting block 84, a connecting rod 85, a second mounting rod 86, a connector 87, a sliding column 88, and a striking assembly (89). The second motor 81 is mounted on a bearing plate, which is fixed to a support plate 531. The output end of the second motor 81 is mounted on the disc 82. The top of the disc 82 is provided with a first mounting rod 83, which is connected to the second mounting rod 86 via a connecting rod 85. A limiting block 84 is provided on the first mounting rod 83 to prevent the connecting rod 85 from slipping off the first mounting rod 83. The second mounting rod 86 is fixed to the connector 87, which is mounted on the sliding column 88. The sliding column 88 passes through the support plate 531 and is connected to the striking assembly 89.
[0026] The striking assembly 89 includes a sleeve 891, a spring 892, a sleeve rod 893, and a striking base 894. The spring 892 is installed inside the sleeve 891. The bottom of the spring 892 is fixed to the sleeve rod 893, and the bottom of the sleeve rod 893 is fixed to the striking base 894. When the stator core is clamped onto the long stator coil, the operator moves the assembled stator core clamp and long stator coil to directly below the striking base 894. The second motor 81 is started to drive the disc 82 to rotate. During the rotation of the disc 82, the sliding column 88 is pressed down and lifted up during one revolution. The sliding column 88 drives the striking base 894 to move synchronously, realizing automatic striking and embedding the long stator coil into the stator core. The spring 892 plays a buffering role.
[0027] Each roller shaft of the traveling roller 7 is equipped with a pressure-sensitive resistor monitoring module. The sensing end of the pressure-sensitive resistor is in direct contact with the surface of the magnetic levitation track to collect the pressure values of the rollers on both sides of the connecting bracket 1 in real time. A preset pressure difference warning threshold is set. When the pressure difference on both sides exceeds the warning threshold, the first motor 41 is started, which causes the threaded rod 42 to rotate and thus drives the moving platform 43 to move, adjusting the position of the air pump 6, and thus adjusting the pressure on both sides of the connecting bracket 1. When the pressure values on both sides return to within the warning threshold, the first motor 41 stops working, completely avoiding the problems of uneven pressure at both ends, such as one-sided weight distribution, skewed walking, and misaligned coil laying, ensuring balanced force and accurate positioning throughout the construction process. The pressure-sensitive resistor adopts a high-precision surface mount design with a response time of ≤0.1s, a monitoring accuracy of ±1N, and is not affected by track vibration or dust, exhibiting extremely high stability.
[0028] The method for using the integrated mounting device for magnetic levitation stator core and long stator coil includes the following steps: Step 1: Move the connecting bracket 1 to the construction site, install the inverted component 2 at one end of the connecting bracket 1 with fixing bolts, install the side connecting bracket 3 at the other end of the connecting bracket 1 with fixing bolts, install the air pressure pump 6 on the moving platform 43, and limit it with the limiting plate 46; Step 2: Connect the feeding component 5 to the inverted frame 23 via the hook 56. Set a pressure difference warning threshold. The pressure value of the rollers on both sides of the connecting bracket 1 is collected in real time by the pressure-sensitive resistor monitoring module. When the pressure difference on both sides exceeds the warning threshold, the first motor 41 is started to rotate the threaded rod 42 and drive the moving platform 43 to move. Adjust the position of the air pump 6 and adjust the pressure on both sides of the connecting bracket 1. When the pressure value on both sides returns to within the warning threshold, the first motor 41 stops working. Step 3: Based on the bending length of the long stator coil, start the hydraulic rod 532 to adjust the position of the moving plate 533. Stop after adjusting to the appropriate position. Bending the long stator coil sequentially through the guide groove 534. After bending, clamp the stator core onto the long stator coil. Step 4: When the stator core is secured on the long stator coil, the operator moves the assembled stator core and long stator coil to directly below the striking base 894, starts the second motor 81 to drive the disc 82 to rotate. During the rotation of the disc 82, the sliding column 88 is pressed down and lifted up. The sliding column 88 drives the striking base 894 to move synchronously, realizing automatic striking and embedding the long stator coil into the stator core. Step 5: After the inlay is completed, move the long stator coil and stator core to the lifting platform 27. Use the infrared laser device on the lifting platform 27 to locate the installation position of the long stator coil and stator core. If the actual installation position does not match the position of the long stator coil and stator core, activate the hydraulic rod 28 to move the bearing platform 26 along the support rod 25 to adjust the position of the long stator coil and stator core. When the adjustment is consistent with the actual installation position, activate the lifting cylinder 24 to move the long stator coil and stator core to the construction site for installation. After installation, use the lifting platform 27 in conjunction with the extension and retraction of the lifting cylinder 24 to shape the long stator coil and stator core, so that the long stator coil and stator core can be firmly fixed together.
