Description

Technical Field

[0001] The invention belongs to the technical field of access control equipment, and in particular relates to an adjustable electromagnetic suspension door. Background Art

[0002] Currently, corporate gates often use folding fence doors to block vehicles and prevent theft. However, folding fence doors require regular maintenance and lubrication, and need to be maintained in a timely manner. Otherwise, there will be problems such as rust, wear, and natural weathering, which will cause noise and vibration in the door transmission. In addition, the current folding fence doors move slowly and may fall over in windy weather. They are low in cost but inconvenient to use and have a short service life. In addition, the existing corporate gates are in a folding form. When one section fails, the entire gate will not work, making maintenance difficult and replacement costly.

[0003] The utility model patent with authorization announcement number CN208448469U discloses an electromagnetically suspended fireproof automatic door, which uses a combination of electromagnets and permanent magnets to suspend the moving door under conductive conditions, reducing friction, reducing wear and increasing service life. However, the moving speed of the moving door is fixed, and the suspension height and forward speed of the moving door cannot be adjusted as needed. Summary of the Invention

[0004] The object of the present invention is to provide an adjustable electromagnetic suspension door with adjustable suspension height and forward speed and double anti-tilt insurance.

[0005] The technical solution adopted by the present invention to solve the technical problem is: an adjustable electromagnetic suspension door, comprising a plurality of suspension door units, a U-shaped electromagnetic track for supporting the movement of the suspension door units, and a door opening for accommodating the suspension door units;

[0006] The suspended door monomer includes a door frame body and a door frame base. The door frame body is located in the door opening. Anti-tilt electromagnets are laterally fixed in the middle of both sides of the door frame body. Anti-tilt electromagnetic sensors are respectively provided on the two side walls in the door opening. The anti-tilt electromagnetic sensors correspond to the anti-tilt electromagnets and are at the same level. The bottom of the door frame body is connected to the door frame base by welding. A U-shaped electromagnet, a controller, and a linear motor stator are fixed to the bottom of the door frame base by bolts. The controller is electrically connected to the U-shaped electromagnet, the linear motor stator, and the anti-tilt electromagnet respectively. The U-shaped electromagnetic track is located below the door frame base and corresponds to the position of the U-shaped electromagnet. The U-shaped electromagnetic track The track is at a different level from the U-shaped electromagnet, and a driving copper plate is provided in the U-shaped electromagnetic track. The U-shaped electromagnetic track and the driving copper plate are electrically connected to the controller respectively. The linear motor stator is used to generate a magnetic field. After the driving copper plate is energized, it generates cutting magnetic flux lines in the magnetic field generated by the linear motor stator. The suspended door obtains power and moves back and forth by cutting the magnetic flux lines. There are several anti-tilt electromagnetic wheels symmetrically distributed on both sides of the door frame base. The anti-tilt electromagnetic wheels correspond to the positions of the U-shaped electromagnetic track. A wheel regulator is connected to the top of each anti-tilt electromagnetic wheel. Each wheel regulator controls the corresponding anti-tilt electromagnetic wheel to turn independently, and the wheel regulator is electrically connected to the controller.

[0007] Furthermore, the ends of both sides of the gantry base are respectively provided with suspension legs, and the suspension legs are at the same magnetic level as the U-shaped electromagnetic track.

[0008] Furthermore, the controller is used to supply power to the U-shaped electromagnet, and the U-shaped electromagnet is energized and operates. At the same time, the U-shaped electromagnetic track at the bottom is energized, the U-shaped electromagnetic track and the U-shaped electromagnet are attracted to each other by opposite charges, and the suspension legs and the U-shaped electromagnetic track generate repulsive force to balance the suction and gravity of the U-shaped electromagnet, lift the suspension door, and electromagnetically drive the suspension door forward and backward. The lifting height of the electromagnetic suspension door is adjusted by adjusting the amount of electricity by the controller.

[0009] Furthermore, an obstacle removal baffle is provided below the end of the gantry base, the top of the obstacle removal baffle is connected to a spring adjuster, and the obstacle removal baffle is connected to the bottom of the gantry base through the spring adjuster.

[0010] Furthermore, anti-collision baffles are respectively provided on both sides of the end of the portal frame base.

[0011] Furthermore, position sensors are respectively installed on both sides of the bottom of the gantry base, and the position sensors are electrically connected to the controller.

[0012] Furthermore, the door frame body includes a door frame top plate, a door panel, a door frame pillar, and a door frame slide rail. The two sides of the door panel are respectively connected to the door frame pillars, the top of the door panel is connected and fixed to the door frame top plate, the bottom of the door panel and the door frame pillars are placed in the door frame slide rail, and the bottom of the door frame slide rail is connected to the door frame base by welding.

[0013] Furthermore, the door frame body is made of hollow stainless steel.

[0014] The present invention has the following beneficial effects:

[0015] 1. The adjustable electromagnetic suspension door of this invention utilizes the principle of magnetic levitation to create a gap with the ground. The suspension legs generate repulsive force through eddy currents to lift the door. A U-shaped electromagnet generates an attractive force, guiding the door frame. When the door frame moves horizontally, the attractive force pulls the door back, preventing damage from collisions and strong winds. The electromagnetic drive allows for smoother, quieter operation without noticeable jolts or vibrations, resulting in energy-saving, low-carbon, and environmentally friendly operation. Compared to traditional folding fence doors, it requires less energy, requires less electricity, and reduces energy waste due to frictional resistance.

[0016] 2. The electromagnetic suspension door of the present invention generates a magnetic field through the electromagnetic coil, which interacts with the electromagnetic driving copper plate at the bottom to generate electromagnetic force to drive the operation. It can cover a longer distance in a shorter time and increase the speed to a higher value in a very short time. It is sensitive and quick to respond, and is faster and more efficient.

[0017] 3. The suspension height and forward speed of the electromagnetic suspension door of the present invention can be continuously adjusted according to the situation, making it faster, more stable and safer.

[0018] 4. The electromagnetic floating door of this invention features dual anti-tilt protection. First, an electromagnetic guide in the door opening prevents the door frame from tipping over and ensures that all doors remain on the designated path, ensuring high-speed and efficient operation. Second, an anti-tilt electromagnetic wheel. In strong winds, the repulsion between the bottom of the floating door and the U-shaped electromagnetic track shifts to an attraction between the anti-tilt wheel and the U-shaped electromagnetic track. This magnetic attraction enhances the anti-tilt effect, providing maximum wind and tip protection.

[0019] 5. The electromagnetic floating door of the present invention is composed of multiple floating door units connected together, and the door frame and door panel are installed in an assembled manner, which is convenient for disassembly and maintenance. It is not only suitable for the needs of corporate doors of various lengths, but also if a section of the door frame is damaged, only a single section of the floating door unit can be replaced instead of all overhauling, which effectively reduces the cost of repair and maintenance, is convenient to operate, and requires less labor input.

[0020] 6. The door is guided by the suction of a U-shaped electromagnet and an anti-tilt electromagnetic wheel. The magnetic force of the U-shaped electromagnet is used to adsorb the floating door. When the floating door deviates from the original track, the magnetic force will guide the floating door back to the original track. When the floating door deviates too much, the deflection of a single anti-tilt electromagnetic wheel can be adjusted to turn the floating door and guide it back to the original route.

[0021] 7. When the floating door cannot be suspended due to power outage, it can be pushed by the anti-tilt electromagnetic wheel to avoid the traffic inconvenience caused by power outage.

[0022] 8. The electromagnetic suspension door of the present invention is environmentally friendly and energy-saving, greatly increases its service life, and avoids frequent maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following are specific embodiments of the present invention to further describe the technical solution of the present invention, but the scope of protection of the present invention is not limited to these embodiments. Any changes or equivalent substitutions that do not deviate from the concept of the present invention are included in the scope of protection of the present invention.

[0031] like Figure 1-6 As shown, an adjustable electromagnetic suspension door includes a plurality of suspension door units, a U-shaped electromagnetic track 9 for supporting the movement of the suspension door units, and a door opening 12 for accommodating the suspension door units.

[0032] The suspended door unit includes a door frame body 1 and a door frame base 2. The door frame body 1 is made of hollow stainless steel. The door frame body 1 is located in the door opening 12. Anti-tilt electromagnets 7 are laterally fixed in the middle of both sides of the door frame body 1. Anti-tilt electromagnetic sensors 11 are respectively provided on the two side walls in the door opening 12. The anti-tilt electromagnetic sensors 11 correspond to the anti-tilt electromagnet 7 in position and are at the same level. The door frame body 1 is subjected to the same-level repulsive force of the anti-tilt electromagnet 7 and the anti-tilt electromagnetic sensor 11 to ensure that the suspended door unit will not tilt.

[0033] The door frame body 1 includes a door frame top plate 1-1, door panels 1-2, door frame pillars 1-3, and door frame slide rails 1-4. The sides of the door panel 1-2 are connected to the door frame pillars 1-3, and the top of the door panel 1-2 is fixedly connected to the door frame top plate 1-1. The door frame top plate 1-1, door frame pillars 1-3, and door panel 1-2 can be connected by splicing, making it easy to assemble and disassemble. The door panel 1-2 is made of aluminum alloy steel plate and can be customized with various patterns as needed. It is not only beautiful but also highly interchangeable to meet the needs of different users. The bottom of the door panel 1-2 and door frame pillars 1-3 is placed in the door frame slide rails 1-4, and the bottom of the door frame slide rails 1-4 is welded to the door frame base 2.

[0034] The two ends of the gantry base 2 are each provided with a suspension leg 13. A U-shaped electromagnet 6, a controller 4, and a linear motor stator 5 are bolted to the bottom of the gantry base 2. The controller 4 is electrically connected to the U-shaped electromagnet 6, the linear motor stator 5, and the anti-tilt electromagnet 7. The controller 4 is used to supply power to the U-shaped electromagnet 6 to ensure its operation. At the same time, the U-shaped electromagnetic track 9 at the bottom is energized. The U-shaped electromagnetic track 9 and the U-shaped electromagnet 6 have opposite charges, and the four suspension legs 13 generate a repulsive force that balances the suction force of the U-shaped electromagnet 6 and the force of gravity, lifting the suspended door. The electromagnetically driven suspended door moves forward and backward. The lifting height of the electromagnetic suspended door is adjusted by adjusting the amount of power by the controller 4. Position sensors are installed on both sides of the bottom of the gantry base 2. The position sensors are not shown in the accompanying drawings. The position sensors are electrically connected to the controller 4 and are used to transmit the lifting height data of the electromagnetic suspended door to the controller.

[0035] The U-shaped electromagnetic track 9 is located below the gantry base 2 and corresponds to the position of the U-shaped electromagnet 6. The U-shaped electromagnetic track 9 and the U-shaped electromagnet 6 attract each other at different levels, and the U-shaped electromagnetic track 9 and the suspension leg 13 repel each other at the same level. The U-shaped electromagnet adsorption and the suspension leg repulsion are coordinated in a way that the repulsion is used for suspension and the adsorption force is used for guidance compensation.

[0036] A driving copper plate 10 is located within the U-shaped electromagnetic track 9. Both the U-shaped electromagnetic track 9 and the driving copper plate 10 are electrically connected to the controller 4. The linear motor stator 5 generates a magnetic field. When energized, the driving copper plate 10 cuts through the magnetic flux lines generated by the linear motor stator 5. This cutting of the magnetic flux lines propels the floating door forward. The linear motor stator 5 can commutate to adjust the direction of the force acting on the cut magnetic flux lines, controlling the door's retraction. Adjusting the current flowing through the linear motor can adjust the door's forward and reverse speeds.

[0037] An obstacle removal baffle 14 is provided below the end of the gantry base 2 of the floating door, which can clear obstacles on the path when traveling, and prevent obstacles from interfering with the adsorption and movement of the floating door. This not only ensures the adsorption effect of the floating door, but also prevents damage to the bottom layer of the floating door. The obstacle removal baffle 14 is connected to the bottom of the gantry base 2 through a spring regulator 16. When the floating door is suspended by magnetic force, the obstacle removal baffle 14 is tightened to the U-shaped electromagnetic track 9 through the spring regulator 16 to clear obstacles; when the floating door is adsorbed on the U-shaped electromagnetic track 9, the spring regulator 16 presses the obstacle removal baffle 14 tightly to the gantry base 2 of the floating door, and prevents the obstacle removal baffle 14 from interfering with the floating door's proximity to the U-shaped electromagnetic track 9.

[0038] Anti-collision baffles 15 are respectively provided on both sides of the end of the electromagnetic suspension door frame base 2, which can avoid rigid collision between suspension doors, effectively improve the service life and avoid damage to the suspension doors.

[0039] Several anti-tilt electromagnetic wheels 3 are symmetrically distributed on either side of the gantry base 2. These wheels 3 correspond to the U-shaped electromagnetic track 9, and each wheel 3 is connected to a wheel adjuster 8 above it. These wheel adjusters 8 are electrically connected to the controller 4. If the electromagnetic floating door is subject to excessive wind and threatens to tilt, position sensors on either side of the bottom of the gantry base 2 sense the floating height. If the two floating heights differ, and the difference exceeds a specified value, the position sensors transmit a signal to the controller 4, which instructs the wheel adjusters 8 to extend the anti-tilt electromagnetic wheels 3 and attach them to the U-shaped electromagnetic track 9. This shifts the floating door's movement from suspension to wheeled motion, effectively resisting wind forces and preventing it from tipping over. Each anti-tilt electromagnetic wheel 3 operates independently. If the floating door deviates from its original trajectory, the position sensors sense it and transmit a signal to the controller 4, which then controls the deflected anti-tilt electromagnetic wheel 3 to rotate, guiding the door back to its original trajectory, effectively tracking it.

[0040] The electromagnetic floating door is composed of multiple floating door units connected together. It is not only suitable for the needs of corporate doors of various lengths, but also if a section of the door frame is damaged, only the single section of the floating door unit can be replaced instead of all overhauling, which effectively reduces the cost of repair and maintenance, is convenient to operate, and requires less labor input.

[0041] Even when the door is completely blocked, the floating door remains partially in the doorway. The anti-tilt electromagnet and anti-tilt electromagnetic sensor act in concert to prevent the door from tilting. The main frame is positioned above the U-shaped electromagnetic track, preventing it from derailing or tipping. The electromagnetic floating door's frame base is massive, stabilizing the door's center of gravity.

[0042] During normal operation, the floating door moves forward and backward through electromagnetic levitation, with extremely low frictional resistance. Compared with traditional folding fence doors, it requires less energy, requires less electricity, and reduces energy waste caused by frictional resistance. The electromagnetically driven door operates more smoothly and quietly, without noticeable jolts or vibrations, making it energy-efficient, low-carbon, and environmentally friendly.

[0043] The electromagnetic levitation door generates a magnetic field through the electromagnetic coil, which interacts with the electromagnetic drive copper plate at the bottom to generate electromagnetic force to drive its operation. Compared with the traditional folding fence door, it has a very obvious speed-up effect (refer to the performance gap between the magnetic levitation train and the ordinary train). It can cover a longer distance in a shorter time and increase the speed to a higher value in a very short time. It responds quickly and sensitively, and is more high-speed and efficient.

[0044] Electromagnetic floating doors feature two anti-tilt safeguards. The first is an electromagnetic guide within the door opening, which not only prevents the door from tipping over but also ensures that all doors remain on the designated path, ensuring high-speed and efficient operation. The second is an anti-tilt electromagnetic wheel, designed for use in strong winds. In strong winds, the repulsion between the door's base and the U-shaped electromagnetic track shifts to an attraction between the anti-tilt wheel and the track. Compared to traditional folding door wheel systems, the magnetic attraction provides superior anti-tilt protection, providing maximum wind and tipping resistance. Adjustable electromagnetic floating doors use suction to guide them if they deviate due to external forces. If excessive deflection causes insufficient suction, the anti-tilt electromagnetic wheel can be controlled to steer the door back to its intended path. This provides the door with a certain degree of rigidity, preventing it from easily deviating from its intended path. While traditional gates have a low, fixed forward speed, electromagnetic floating doors can adjust their height and forward speed continuously, providing faster, more stable, and safer operation.

[0045] The present invention is not limited to the above-mentioned embodiments. Anyone should be aware that any structural changes made under the guidance of the present invention, and any technical solutions that are the same or similar to those of the present invention, fall within the scope of protection of the present invention.
