Description

Technical Field

[0001] This utility model relates to the field of magnetic levitation door technology, specifically a linear motor magnetic levitation door that can achieve rapid opening and closing. Background Technology

[0002] Magnetic levitation doors, as a type of automated door, utilize electromagnetic principles to achieve levitation and movement, avoiding the frictional losses of traditional mechanical tracks and improving opening and closing efficiency. The introduction of linear motor technology further optimizes the drive method, directly controlling the door's displacement through linear motion, ensuring that the door completes opening or closing actions in a short time, meeting the needs of modern buildings for efficient passage and security. In high-frequency usage scenarios such as transportation hubs and commercial centers, rapid response and low-noise operation have become key advantages of this type of door.

[0003] Currently, the levitation gap of magnetic levitation doors is usually very small. During long-term use, dust and particles will continuously accumulate on the inner wall of the track, which will directly fill or squeeze the levitation gap, thereby breaking the balance of electromagnetic force. To address this, we propose a linear motor magnetic levitation door that can achieve rapid opening and closing. Utility Model Content

[0004] The purpose of this invention is to provide a linear motor magnetic levitation door that can achieve rapid opening and closing, in order to solve the problem mentioned in the background art that dust and particulate matter inside the track will disrupt the balance of electromagnetic force.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a linear motor magnetic levitation door capable of rapid opening and closing, comprising: a magnetic levitation door body; magnetic levitation tracks for moving the magnetic levitation door body are respectively installed above and below the magnetic levitation door body, and a magnetic levitation track cleaning mechanism is installed on one side of the magnetic levitation door body. The cleaning mechanism is in contact with the inner wall of the magnetic levitation track, and a linear motor is installed on the inner wall of the magnetic levitation track. The linear motor drives the magnetic levitation door body to open and close inside the magnetic levitation track. At the same time, the cleaning mechanism effectively cleans the dust and particles remaining on the inner wall of the magnetic levitation track by moving the magnetic levitation door body, preventing the dust and particles from disrupting the balance of the magnetic levitation door body.

[0006] The cleaning mechanism includes a movable plate and a cleaning plate inside the movable plate. The bottom of the cleaning plate is in contact with the inner wall of the magnetic levitation track, and a rotating rod is fixedly installed inside the cleaning plate.

[0007] One end of the rotating rod extends into the interior of the moving plate and is rotatably connected to it. A baffle is installed on the back of the cleaning plate, and the top of the baffle is fixed to the moving plate. The side of the moving plate away from the cleaning plate is in contact with the side of the magnetic levitation door.

[0008] The movable plate has a movable frame fixedly installed inside, and one end of the movable frame extends into the interior of the magnetic levitation gate. A support plate is fixedly installed on the inner wall of the movable frame, and a telescopic spring is fixedly installed on the top of the support plate.

[0009] The top of the telescopic spring is fixedly equipped with a pressing plate, and the outer surface of the pressing plate is in contact with the inner wall of the moving frame. A limit block is fixedly installed on the top of the pressing plate, and one end of the limit block passes through the moving frame and extends into the interior of the magnetic levitation door, and the cleaning mechanism is engaged with one side of the magnetic levitation door.

[0010] One side of the magnetic levitation gate is equipped with a connecting frame, and a collection frame is snapped into the inside of the connecting frame.

[0011] The top of the collection frame is fixedly equipped with an extraction block, which is in contact with the outer surface of the connecting frame, and the connecting frame is in contact with one side of the magnetic levitation track.

[0012] This utility model has at least the following beneficial effects: By incorporating a cleaning mechanism, linear motor, and collection frame, the linear motor efficiently drives the magnetic levitation gate to move smoothly, ensuring precise and controllable movement throughout the entire process. During this process, the moving plate and cleaning plate closely follow the movement of the magnetic levitation gate, achieving a completely synchronized motion trajectory and avoiding any lag or deviation. The cleaning plate is specifically designed to penetrate deep into the magnetic levitation track, continuously pushing residual dust and fine particles towards the connecting frame. This ensures that debris smoothly enters the internal storage space of the collection frame, effectively preventing dust and particles from directly filling or crowding the critical suspension gaps on the inner wall of the track. This maintains a stable balance of electromagnetic force and prevents the suspension system from failing due to the accumulation of impurities. At the same time, the extraction block adopts a convenient design, allowing operators to quickly remove dust and particles from the collection frame after the cleaning cycle, simplifying the maintenance process, ensuring the equipment is clean and efficient, and facilitating continuous use without interruption of operation.

[0015] 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.

[0016] Example 1 Please see Figures 1 to 5 This utility model provides a technical solution: a linear motor magnetic levitation gate capable of rapid opening and closing, comprising: a magnetic levitation gate body 1; magnetic levitation tracks 2 for moving the magnetic levitation gate body 1 are respectively installed above and below the magnetic levitation gate body 1, and a magnetic levitation track 2 cleaning mechanism 3 is installed on one side of the magnetic levitation gate body 1, the cleaning mechanism 3 being in contact with the inner wall of the magnetic levitation track 2; a linear motor 12 is installed inside the magnetic levitation track 2, the stator of the linear motor 12 is composed of an iron core and windings, and is usually integrated in the top structure of the magnetic levitation track 2; the mover of the linear motor 12 is installed on the top of the magnetic levitation gate body 1, and the mover is usually made of a permanent magnet or a highly conductive material; when the linear motor 12 is running, the stator... After being electrified, a traveling wave magnetic field is generated. The permanent magnet on the mover interacts with the magnetic field of the stator, generating a thrust to drive the magnetic levitation gate 1 to translate, thereby enabling the magnetic levitation gate 1 to open and close inside the magnetic levitation track 2. The linear motor 12 not only provides driving force but also enables the magnetic levitation gate 1 to levitate through electromagnetic force, reducing friction and wear. At the same time, the cleaning mechanism 3 effectively cleans the dust and particles remaining on the inner wall of the magnetic levitation track 2 through the movement of the magnetic levitation gate 1, preventing dust and particles from disrupting the balance of the magnetic levitation gate 1. Through the setting of the linear motor 12, the opening and closing movement of the magnetic levitation gate 1 can be effectively realized, while ensuring the stability of the magnetic levitation gate 1 during the movement.

[0017] The cleaning mechanism 3 includes a movable plate 31 and a cleaning plate 32 inside the movable plate 31. The bottom of the cleaning plate 32 is in contact with the inner wall of the magnetic levitation track 2, and a rotating rod 33 is fixedly installed inside the cleaning plate 32. The rotating rod 33 allows the cleaning plate 32 to move inside the movable plate 31. When the movable plate 31 returns to its original position, the cleaning plate 32 comes into contact with the particles inside the magnetic levitation track 2 that have not been cleaned. The rotating rod 33 then flips the cleaning plate 32 so that the cleaning plate 32 can pass through the particles smoothly, preventing the particles that have not been cleaned from entering the magnetic levitation track 2 along with the cleaning plate 32.

[0018] One end of the rotating rod 33 extends into the interior of the movable plate 31 and is rotatably connected to it. A baffle 34 is installed on the back of the cleaning plate 32, and the top of the baffle 34 is fixed to the movable plate 31. The side of the movable plate 31 away from the cleaning plate 32 is in contact with the side of the magnetic levitation door 1. With the setting of the baffle 34, when the movable plate 31 moves, one end of the cleaning plate 32 is in contact with the inner wall of the magnetic levitation track 2 and cleans the dust and particles inside it. When fine particles come into contact with the cleaning plate 32, the cleaning plate 32 will rotate towards the baffle 34 with the help of the rotating rod 33 and come into contact with the baffle 34. With the help of the baffle 34, particles can be effectively prevented from passing through the bottom of the cleaning plate 32 and the dust and particles are cleaned into the interior of the collection frame 10.

[0019] A movable frame 4 is fixedly installed inside the movable plate 31, and one end of the movable frame 4 extends into the interior of the magnetic levitation gate 1. A support plate 5 is fixedly installed on the inner wall of the movable frame 4, and a telescopic spring 6 is fixedly installed on the top of the support plate 5. By setting the movable frame 4, the position of the telescopic spring 6 and the support rod can be restricted, and the positional relationship between the movable plate 31 and the magnetic levitation gate 1 can be connected.

[0020] A pressing plate 7 is fixedly installed on the top of the telescopic spring 6, and the outer surface of the pressing plate 7 is in contact with the inner wall of the moving frame 4. A limiting block 8 is fixedly installed on the top of the pressing plate 7, and one end of the limiting block 8 passes through the moving frame 4 and extends into the interior of the magnetic levitation door 1, and engages the cleaning mechanism 3 on one side of the magnetic levitation door 1. By setting the pressing plate 7, the limiting block 8 can be removed from the interior of the magnetic levitation door 1 by its own movement, and the connection between the magnetic levitation door 1 and the moving plate 31 can be released, which facilitates the subsequent quick replacement of the cleaning plate 32 by the staff.

[0021] A connecting frame 9 is installed on one side of the magnetic levitation door 1, and a collection frame 10 is snapped into the inside of the connecting frame 9.

[0022] An extraction block 11 is fixedly installed on the top of the collection box 10, and the extraction block 11 is in contact with the outer surface of the connecting frame 9. The connecting frame 9 is in contact with one side of the magnetic levitation track 2. The extraction block 11 facilitates the quick cleaning of dust inside the collection box 10 by subsequent staff, and also facilitates installation.

[0023] The working principle of a linear motor magnetic levitation door with rapid opening and closing based on an embodiment is as follows: When the magnetic levitation door needs to be opened or closed, the linear motor 12 is started, and its output end applies force to the magnetic levitation door body 1, driving it to slide rapidly on the magnetic levitation track 2, achieving smooth and efficient opening and closing action. During this process, the airflow generated by the movement of the magnetic levitation door body 1 carries dust and other impurities into the cleaning mechanism 3 area. The cleaning plate 32 is engaged with one side of the magnetic levitation door body 1 through the moving plate 31, automatically cleaning impurities on the track surface and guiding the dust into the collection frame 10. If the cleaning plate 32 needs to be replaced, the operator presses the pressing plate 7, the telescopic spring 6 is compressed, causing the pressing plate 7 to move along the inner wall of the moving frame 4, driving the limit block 8. Completely withdraw from inside the magnetic levitation gate 1 to disconnect it from the moving plate 31. Then, the cleaning plate 32 can be easily disassembled and replaced. Simultaneously, the collection frame 10 is secured inside the mounting plate via the connecting frame 9. After dust accumulation, workers can grasp the extraction block 11 and pull out the collection frame 10 for cleaning, then re-insert it into the connecting frame 9, ensuring convenient installation. The overall principle is based on the synergistic effect of magnetic levitation technology and a linear motor. Magnetic levitation reduces frictional resistance, while the linear motor provides precise linear drive. Combined with the modular design of the cleaning mechanism 3, this not only achieves rapid response and stable operation of the gate but also facilitates maintenance and cleaning, improving equipment lifespan and efficiency. The overall operation process is now complete.
