Description

Technical Field

[0001] This utility model relates to the field of cargo lifting and transportation technology, and in particular to a magnetic levitation transportation device. Background Technology

[0002] In modern manufacturing, the transportation of workpieces and materials is essential. Traditional transportation systems typically use servo motors or stepper motors for driving force. However, traditional transportation systems are space-consuming, energy-intensive, inefficient, and lack flexibility in transport, making it impossible to quickly move workpieces or materials to designated locations. They also cannot be readily available for immediate use, as workpieces or materials cannot be moved or their height adjusted during transportation, requiring manual handling to different heights, which is inconvenient. For the installation and transportation of small modular equipment (such as bucket screens and workpieces), multiple transportation devices need to operate simultaneously, and each device needs to be installed and disassembled before and after use, making the process cumbersome and reducing the installation efficiency of modular equipment.

[0038] 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.

[0039] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0040] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] For ease of description below, an XYZ coordinate system is established, defining the length direction of the magnetic levitation transport device as the X-axis, the width direction as the Y-axis, and the height direction as the Z-axis. It is understood that the coordinate system of the magnetic levitation transport device can be flexibly set according to actual needs; this application only provides an example and should not be considered a specific limitation thereof.

[0042] Please see Figure 1 , Figure 1 This is a partial structural diagram showing the connection between the movable base 1, the lifting mechanism, and the first magnetic levitation track 3 provided in the embodiments of this application; the magnetic levitation transportation device includes the movable base 1, the lifting mechanism, the first magnetic levitation track 3, the magnetic levitation drive mechanism 4, the bearing platform 5, and the lifting mechanism 6.

[0043] In some embodiments, the movable base 1 includes two spaced-apart support beams 14 and a plurality of spaced-apart support longitudinal beams 15. The support longitudinal beams 15 are mounted between the two support beams 14 and are fixedly connected to the support beams 14. In some examples, the support beams 14 may extend along the X-axis direction, and the support longitudinal beams 15 may extend along the Y-axis direction.

[0044] In other embodiments, the movable base 1 includes two spaced-apart support beams 14 and a plurality of spaced-apart support longitudinal beams 15. The support beams 14 are mounted between the two support longitudinal beams 15 and are fixedly connected to the support longitudinal beams 15. In some examples, the support beams 14 may extend along the X-axis direction, and the support longitudinal beams 15 may extend along the Y-axis direction.

[0045] In some examples, the bottom of the supporting crossbeam 14 may be equipped with multiple movable wheels 12 driven by the motor 11 and auxiliary supports 13; in other examples, the bottom of the supporting longitudinal beam 15 may be equipped with multiple movable wheels 12 and auxiliary supports 13 driven by the motor 11; in still other examples, both the bottom of the supporting crossbeam 14 and the supporting longitudinal beam 15 may be equipped with movable wheels 12 and auxiliary supports 13 driven by the motor 11. The movable wheels 12 are used to drive the magnetic levitation transport device to move on the ground, and the auxiliary supports 13 extend and retract by rotation. When the magnetic levitation transport device stops running, the movable wheels 12 are prevented from moving, and the rotating auxiliary supports 13 are used to limit the movement of the movable base 1, thereby improving the safety performance of the magnetic levitation transport device.

[0046] In some embodiments, the movable base 1 has multiple sets of lifting mechanisms spaced apart along the Y-axis on the support beam 14. Each set of lifting mechanisms includes multiple hydraulic lifting rods 21 spaced apart along the X-axis. Each set of lifting mechanisms is equipped with a first magnetic levitation track 3. The first magnetic levitation track 3 can extend along the X-axis, and the hydraulic lifting rods 21 extend along the Z-axis to adjust the height of the first magnetic levitation track 3. The structure is simple and easy to operate.

[0047] For example, in each set of lifting mechanisms, the number of hydraulic lifting rods 21 can be two, three, four or five, etc. The more hydraulic lifting rods 21 there are, the more stable the bottom support of the first magnetic levitation track 3 becomes.

[0048] In other implementations, a first magnetic levitation track 3 may be installed on two hydraulic lifting rods 21 opposite each other in two adjacent sets of lifting mechanisms.

[0049] In some embodiments, one end of each hydraulic lifting rod 21 can be fixedly connected to the supporting beam 14 via a bottom fixing seat 16, and the other end of each hydraulic lifting rod 21 can be fixedly connected to the first magnetic levitation track 3 via a top fixing seat 17. In this way, by setting the bottom fixing seat 16 and the top fixing seat 17, the connection strength between the hydraulic lifting rod 21 and the movable base 1 and the first magnetic levitation track 3 is improved.

[0050] In other embodiments, each hydraulic lifting rod 21 has multiple reinforcing ribs at its bottom along the circumference of the hydraulic lifting rod 21, and the reinforcing ribs are connected to the bottom fixing seat 16. In addition, each hydraulic lifting rod 21 has multiple reinforcing ribs at its top along the circumference of the hydraulic lifting rod 21, and the reinforcing ribs are connected to the top fixing seat 17. This helps to improve the connection strength between the hydraulic lifting rod 21 and the top fixing seat 17 and the bottom fixing seat 16.

[0051] Please see Figure 2 Combined Figure 1 , Figure 2This is a partial structural diagram of the magnetic levitation drive mechanism 4 installed on the first magnetic levitation track 3. A first space a is defined between two adjacent sets of lifting mechanisms. The magnetic levitation drive mechanism 4 is mounted above the first space a. A first kinetic energy braking module 31 is installed on each of the first magnetic levitation tracks 3. Drive beams 41 are installed at both ends of the first magnetic levitation track 3, which are driven to move along the first magnetic levitation track 3 by the first kinetic energy braking module 31. The drive beams 41 extend along the X-axis. Multiple second magnetic levitation tracks 42 are installed between the drive beams 41 at both ends. The second magnetic levitation tracks 42 can extend along the Y-axis. A second space b is defined between two adjacent second magnetic levitation tracks 42.

[0052] For example, multiple first kinetic energy braking modules 31 can be installed on the first magnetic levitation track 3. The more first kinetic energy braking modules 31 there are, the greater the kinetic energy of the first kinetic energy braking modules 31 driving the magnetic levitation drive mechanism 4, and the higher the transportation efficiency.

[0053] Specifically, the drive beam 41 has a first notch 411 on the side facing the first magnetic levitation track 3, and the first kinetic braking module 31 is located within the first notch 411. Several stators c are installed on the first magnetic levitation track 3. The first kinetic braking module 31 includes a motor rotor f, a three-phase armature winding e, a mover d, and a U-shaped mover mounting seat k. The U-shaped mover mounting seat k of the first kinetic braking module 31 is covered by an open end cap on the first magnetic levitation track 3. The open end cap of the U-shaped mover mounting seat k of the second kinetic braking module 43 is covered by an open end cap on the second magnetic levitation track 42. The motor rotor f and the three-phase armature winding e are installed on the outer side of the upper wall of the U-shaped mover mounting seat k, and the mover d is installed on the inner side of the upper wall of the mover mounting seat k. For example, the mover d can be a permanent magnet.

[0054] For example, the shape of the first notch 411 may include, but is not limited to, an inverted U-shape, a semi-circle, a cone shape or other irregular shapes, as long as the first notch 411 has space to accommodate the first kinetic braking module 31, and the shape is not limited here.

[0055] In other embodiments, the three-phase armature winding e can also be mounted on the stator c.

[0056] Please see Figure 3 , Figure 3 This is a partial enlarged view of the first kinetic braking module 31 installed on the first magnetic levitation track 3 or the second kinetic braking module 43 installed on the second magnetic levitation track 42. The motor rotor f achieves coordinated control of levitation force and driving force through electromagnetic coupling. When the stator c is energized, the stator c and the rotor d generate a vertically upward levitation force under the interaction of the magnetic field, which can counteract the gravity of the magnetic levitation drive mechanism 4.

[0057] The three-phase armature winding e (U, V, W phases) is used to generate a controllable electromagnetic field. Driven by the motor rotor f, it generates a traveling wave magnetic field that propagates along the direction of the first magnetic levitation track 3. The mover d is cut by the traveling wave magnetic field, and the interaction between the permanent magnet magnetic field and the traveling wave magnetic field induces a traction force, which pushes the magnetic levitation drive mechanism 4 to move on the first magnetic levitation track 3. By providing a constant magnetic field and current interaction, it realizes the efficient conversion of electrical energy and mechanical energy. It has the characteristics of simple structure and easy installation.

[0058] In some embodiments, the extension direction of the second magnetic levitation track 42 is perpendicular to the extension direction of the first levitation track 3. This ensures that the first levitation track 3 and the second magnetic levitation track 42 run in different directions, thereby guaranteeing the diversity of transportation paths for the magnetic levitation transport device.

[0059] Please see Figure 4 , Figure 4 This is a partial structural diagram of the support platform 5 installed on the second magnetic levitation track 42. In some embodiments, a second kinetic energy braking module 43 is installed on the second magnetic levitation track 42, and the support platform 5 is installed on the second magnetic levitation track 42 and driven to move along the second magnetic levitation track by the second kinetic energy braking module 43.

[0060] For example, multiple second kinetic energy braking modules 43 can be installed on the second magnetic levitation track 42. The more second kinetic energy braking modules 43 there are, the greater the kinetic energy that the second kinetic energy braking modules 43 drive the carrying platform 5, and the higher the transportation efficiency.

[0061] Specifically, the supporting platform 5 has a second notch 51 on the side facing the second magnetic levitation track, and the second kinetic energy braking module 43 is located within the second notch 51. (Continue reading...) Figure 3 The motor rotor f achieves coordinated control of levitation force and driving force through electromagnetic coupling. When the stator c is energized, the stator c and the rotor d generate a vertically upward levitation force under the interaction of the magnetic field, which can counteract the gravity of the bearing platform 5.

[0062] For example, the shape of the second notch 51 may include, but is not limited to, an inverted U-shape, a semi-circle, a cone shape or other irregular shapes. The main requirement is that the second notch 51 has space to accommodate the second kinetic braking module 43, and the shape is not limited here.

[0063] The three-phase armature winding e (U, V, W phases) is used to generate a controllable electromagnetic field. Driven by the motor rotor f, it generates a traveling wave magnetic field that propagates along the direction of the second magnetic levitation track 42. The mover d is cut by the traveling wave magnetic field, and the interaction between the permanent magnet magnetic field and the traveling wave magnetic field generates a traction force, which pushes the bearing platform 5 to move on the second magnetic levitation track 42. By providing a constant magnetic field and current interaction, it realizes the efficient conversion of electrical energy and mechanical energy. It has the characteristics of simple structure and easy installation.

[0064] In some embodiments, the first kinetic braking module 31 and the second kinetic braking module 43 can each be configured as multiple. The more first kinetic braking modules 31 and the second kinetic braking modules 43 there are, the higher the efficiency of the magnetic levitation transport device in transporting goods, which is beneficial to ensuring transport efficiency.

[0065] Please see Figure 5 , Figure 5 This is a partial structural diagram of the lifting mechanism 6 mounted on the main beam 52 of the support platform 5. In some embodiments, the lifting mechanism 6 is movably mounted on the bottom of the support platform 5 via a sliding seat 61 (the sliding seat 61 is a well-established and known product, and will not be described in detail here). The lifting mechanism 6 passes through the second space b and the first space a. The lifting mechanism 6 rises and falls along the height direction of the magnetic levitation transport device via an electric drum 62. Specifically, the bottom of the support platform 5 is provided with a main beam 52 extending along the second magnetic levitation track. The main beam 52 extends along the Y-axis direction, and slide rails 511 are provided on both sides of the main beam 52. The wheels on both sides of the sliding seat 61 are engaged with the slide rails 511 on both sides, realizing movement along the slide rails 511 on both sides.

[0066] In some other embodiments, the main beam 52 may be provided with a slide rail 511 on one side, and the sliding seat 61 is a single-sided wheel. The single-sided wheel of the sliding seat 61 is locked on the slide rail 511 to realize single-sided movement along the slide rail 511.

[0067] The lifting mechanism 6 also includes a lifting rope 63 and a hook 64. The sliding seat 61 is driven by the drive motor 11 to move along the slide rail 511. An electric drum 62 is mounted on the sliding seat 61. One end of the lifting rope 63 is fixedly connected to the electric drum 62, and the other end is connected to the hook 64. The electric drum 62 rotates to wind up and unwind the lifting rope 63 along the Z-axis. By setting up the lifting mechanism 6 to move goods using the second space b and the first space a, the usability of the magnetic levitation transport device is increased, and the operability of the magnetic levitation transport device is improved.

[0068] In some embodiments, anti-collision blocks 44 are provided at both ends of the extension direction of each second magnetic levitation track, and the anti-collision blocks 44 are installed on the upper part of the drive beam 41 through the support frame 45. The anti-collision blocks 44 are installed at both ends of the extension direction of the drive beam 41. The support frame 45 is used to raise the anti-collision blocks 44 so that the anti-collision blocks 44 can play the role of protecting the bearing platform 5. The anti-collision blocks 44 are set to ensure the safe operation of the magnetic levitation transport device.

[0069] For example, the anti-collision block 44 includes, but is not limited to, a polyurethane buffer.

[0070] Based on the above, the magnetic levitation transport device also includes a control cabinet 7, which is installed on the movable base 1 and is used to control the opening, closing and operation of the magnetic levitation transport device.

[0071] Specifically, control cabinet 7 includes a PLC controller, a control panel, a wireless remote controller, and a wireless communication module. The PLC controller includes a lifting control module and a walking control module. The lifting control module is used to drive the lifting mechanism to rise and fall. The walking control module is used to control the movement of the moving wheels 12, the first kinetic energy braking module 31, and the second kinetic energy braking module 43. The PLC controller is communicatively connected to the wireless communication module, the control panel, and the wireless remote controller.

[0072] The magnetic levitation transport device provided in this application embodiment combines a lifting mechanism, a first magnetic levitation track 3, a magnetic levitation drive mechanism 4, a cargo platform 5, and a hoisting mechanism 6 to enable the magnetic levitation transport device to move along the X-axis, Z-axis, and Y-axis directions. This makes the method of transporting workpieces or materials more flexible, improves the portability of lifting and positioning, and can transport materials to different heights at designated locations according to usage needs. It features stable and accurate lifting, frequent start-up, and flexible operation, significantly improving the flexibility, practicality, safety, and accuracy of the magnetic levitation transport device.

[0073] The magnetic field strength can be adjusted by regulating the current supplied to the stator C, thereby controlling the speed of the magnetic levitation transport device, reducing the inertia of the motor during rapid braking, which is beneficial for smooth transport, saves energy, and significantly improves transport efficiency.

[0074] Furthermore, this magnetic levitation transport device is lightweight, simple in structure, easy to assemble and disassemble, convenient to carry and move, suitable for use in narrow spaces, and can be adjusted in position according to usage needs to improve work efficiency. It features stable and accurate lifting, frequent start-up, and flexible operation.

[0077] Under the influence of magnetic field and current, the mover d, stator c and three-phase armature winding e drive the first kinetic energy braking module 31 and the second kinetic energy braking module 43 to levitate; the first kinetic energy braking module 31 and the second kinetic energy braking module 43 are activated, the first kinetic energy braking module 31 pushes the magnetic levitation drive mechanism 4 to move to the designated position along the length direction of the magnetic levitation transport device, and the first kinetic energy braking module 31 drives the carrying platform 5 and the cargo to move to the specific position along the width direction of the magnetic levitation transport device.

After the goods 5 reach the designated position, stop the operation of the lifting control module through the control panel of the control cabinet, lock the support height of the bearing platform, and then the loading and unloading work can be carried out.
