Description

Technical Field

[0001] This utility model relates to the field of platform sliding doors, and more specifically, to a magnetic levitation platform sliding door. Background Technology

[0002] In railway transportation, the efficiency of platform organization and guidance is directly related to passenger safety and train punctuality. Currently, most railway platforms adopt the "train arrival guidance" operation mode, that is, after the train enters the station and stops, platform staff manually guide waiting passengers to the corresponding platform boarding area according to the specific location of the train carriages.

[0003] To improve the accuracy and safety of guidance, some modern platforms have installed controllable sliding doors at the entrances connecting the waiting hall and different platforms. These sliding doors are usually operated by staff through a control terminal after confirming the train's arrival information, allowing them to slide left and right precisely to align with the current train's door position. This creates a safe and orderly boarding path for passengers. This design, to some extent, avoids passengers blindly searching for carriages on the spacious platform and improves the order of platform management.

[0004] However, the existing platform sliding door guidance system still has obvious shortcomings in intelligence and functional limitations, mainly in the following two aspects:

[0005] First, the level of intelligence is low, and it relies on manual operation. The entire guidance process depends heavily on the on-site judgment and manual control of the staff. The staff need to pay attention to the train's arrival at the station at all times and receive dispatch instructions before they can operate the sliding doors. This not only increases the cost of human resources, but also may cause delays in manual response during peak passenger flow, affecting the guidance efficiency. In addition, there is a risk of misjudgment or misoperation in manual operation, which may cause the sliding doors to fail to be accurately aligned with the train doors, resulting in safety hazards.

[0006] Secondly, the door structure is simple, and its adaptability and adjustment range are limited. Existing sliding doors can usually only move their inherent single or double doors. The adjustment range of their overall width is limited by the physical size of the door itself. When encountering complex train types (such as short trains and long trains running together), large differences in door spacing, or the need to temporarily open a wider passage to manage large passenger flows, the limited adjustment capacity of existing sliding doors becomes inadequate. They cannot dynamically and significantly change the effective passage width according to the needs of the site, which limits their application flexibility in diverse operating scenarios.

[0007] Therefore, it is necessary to propose a magnetic levitation platform sliding door to solve the above problems. Utility Model Content

[0008] To overcome at least one of the defects (deficiencies) of the prior art described above, this utility model provides a magnetic levitation platform sliding door.

[0009] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a magnetic levitation platform sliding door, used to be installed on a platform passage where trains can be observed to enter the station, including a train type identifier, a magnetic levitation left sliding door, a control box with a controller, a magnetic levitation right sliding door and a track platform;

[0010] The track platform is set on the platform passage where the train can be observed to enter the station. The track platform is equipped with a magnetic levitation motor stator, a magnetically conductive track and a positioning sensor.

[0011] The magnetic levitation left sliding door, the control box, and the magnetic levitation right sliding door are connected in sequence. The train model identifier is installed on the magnetic levitation left sliding door and / or the magnetic levitation right sliding door and is connected to the controller in the control box.

[0012] The control box is equipped with a magnetic levitation motor mover and an electromagnet. When the electromagnet is energized, it lifts the control box relative to the magnetically conductive track. When the magnetic levitation motor mover is energized, it repels the magnetic levitation motor stator, allowing the magnetic levitation left sliding door, the control box, and the magnetic levitation right sliding door to be movably mounted on the track platform.

[0013] The control box is equipped with a positioning sensor that interacts with the positioning sensor on the track platform. The positioning sensor is connected to the controller. By setting up a track platform on the platform passage where the train's arrival can be observed, and installing a magnetic levitation motor stator and positioning sensor on the track platform, and placing a train model identifier on the control box and connecting it to the controller inside the control box, the train model identifier can quickly determine the train's arrival status and automatically identify the train model and number. This allows the controller to better control the position and width of the opened magnetic levitation left and right sliding doors. This setup can intelligently guide passengers. In addition, compared to existing sliding doors, this solution places the controller in the control box and places the magnetic levitation left and right sliding doors on both sides of the control box. Therefore, when moving, the magnetic levitation left sliding door, the control box, and the magnetic levitation right sliding door move simultaneously, thus achieving a greater range of changes in the effective passage width and enabling flexible application in diverse operating scenarios.

[0014] Furthermore, it also includes radar detectors, which are installed on the magnetic levitation left sliding door and / or the magnetic levitation right sliding door and connected to the controller in the control box. The radar detectors can sense people inside the platform.

[0015] Furthermore, the train model identifier is a high-definition camera for model recognition. The high-definition camera for model recognition is installed on the magnetic levitation left sliding door and / or the magnetic levitation right sliding door and is connected to the controller in the control box. By setting up the high-definition camera for model recognition, the train model and the train's arrival status can be automatically identified, thereby facilitating the controller to control the position and width of the magnetic levitation left sliding door and the magnetic levitation right sliding door that need to be opened.

[0016] Furthermore, the control box includes a control box body, a support frame, a connecting plate, a tank track groove, status indicator lights, and a support plate with positioning holes;

[0017] The magnetic levitation motor actuator, electromagnet, and positioning sensor are all mounted on the support frame.

[0018] The connecting plate is set on the top of the support frame, the support plate is set on the connecting plate, and the control box body is set on the support plate with positioning holes by positioning components.

[0019] The status indicator light is located on the control box body;

[0020] The controller is housed within the control box. The controller's wires are connected via a tank chain cable groove to the train model identifier, the magnetic levitation motor mover, status indicator lights, an electromagnet, and a positioning sensor. Through the arrangement of the magnetic levitation motor mover and stator, when the magnetic levitation motor mover is energized, the mover and stator repel each other, allowing the support frame to move more effectively on the track platform. The positioning sensor detects the positioning of the support frame. Furthermore, the support plate supports the control box. When the support frame is in position, the status indicator lights provide corresponding reminders.

[0021] Furthermore, the support frame is provided with sliders on both sides, and the track platform is provided with slide rails. The support frame is fitted onto the slide rails of the track platform by the sliders. The sliders and slide rails facilitate the limited movement of the support frame.

[0022] Furthermore, the bottom of the magnetic levitation left sliding door and the magnetic levitation right sliding door are provided with an extension side. The bottom of the magnetic levitation left sliding door and the magnetic levitation right sliding door are fixed to the support plate with positioning holes through the extension side. By setting the extension side, the bottom of the magnetic levitation left sliding door and the magnetic levitation right sliding door can also be stably fixed to the support plate, thereby strengthening the fixation of the magnetic levitation left sliding door and the magnetic levitation right sliding door.

[0023] Furthermore, the support frame is provided with reinforcing ribs, which are fitted to both sides of the magnetic levitation motor mover. The reinforcing ribs can strengthen and fix the magnetic levitation motor mover.

[0024] Furthermore, the bottom of the magnetic levitation left sliding door and the magnetic levitation right sliding door are equipped with apron anti-pinch brushes. By setting the apron anti-pinch brushes, it is possible to prevent the magnetic levitation left sliding door and the magnetic levitation right sliding door from pinching passengers during the movement.

[0025] Furthermore, the magnetic levitation left sliding door and the magnetic levitation right sliding door are made of glass. In practical applications, the magnetic levitation left sliding door and the magnetic levitation right sliding door can also be made of other materials, which are all alternative solutions that are easy for those skilled in the art to think of.

[0026] Furthermore, the track platform is provided with wire grooves, which facilitate wiring and are simple and practical.

[0027] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0028] This utility model discloses a magnetic levitation platform sliding door. By setting up a track platform on the platform passageway where train arrival can be observed, and installing a magnetic levitation motor stator and positioning sensors on the track platform, and placing a train model identifier on the control box and connecting it to the controller inside the control box, the train model identifier can quickly determine the train's arrival status and automatically identify the train model and number. This allows the controller to better control the position and width of the opened magnetic levitation left and right sliding doors. This setup intelligently guides passengers. Furthermore, compared to existing sliding doors, this solution places the controller in the control box and positions the magnetic levitation left and right sliding doors on either side of the control box. Therefore, during movement, the magnetic levitation left sliding door, control box, and magnetic levitation right sliding door move simultaneously, thus achieving a greater range of changes in the effective passage width and enabling flexible application in diverse operational scenarios.

The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0040] like Figure 1-5As shown, a magnetic levitation platform sliding door is installed on a platform passage 1 where train arrival can be observed. It includes a train type identifier, a magnetic levitation left sliding door 2, a control box 4 with a controller 3, a magnetic levitation right sliding door 5, and a track platform 6. The track platform 6 is installed on the platform passage 1 where train arrival can be observed, and it is equipped with a magnetic levitation motor stator 7, a magnetically conductive track 28, and a positioning sensor 8. The magnetic levitation left sliding door 2, the control box 4, and the magnetic levitation right sliding door 5 are connected sequentially. The train type identifier is installed on the magnetic levitation... The left sliding door 2 and / or the right sliding door 5 are suspended and connected to the controller 3 inside the control box 4. The control box 4 is equipped with a magnetic levitation motor mover 9 and an electromagnet 26. When the electromagnet 26 is energized, it lifts the control box 4 relative to the magnetically conductive track 28. When the magnetic levitation motor mover 9 is energized, it repels the magnetic levitation motor stator 7, allowing the magnetic levitation left sliding door 2, the control box 4, and the magnetic levitation right sliding door 5 to be movably mounted on the track platform 6. The control box 4 is equipped with a positioning sensor that connects to the track platform 6. The system includes a positioning sensor 10 that senses the interaction between sensors 8 and the system. The positioning sensor 10 is connected to the controller 3. A track platform 6 is installed on the platform passage 1 where the train's arrival can be observed. The track platform 6 is equipped with a magnetic levitation motor stator 7 and a positioning sensor 8. The train model identifier is installed on the control box 4 and connected to the controller 3 inside the control box 4. Therefore, the train model identifier can quickly determine the train's arrival status and automatically identify the train model and number. This allows the controller 3 to better control the position and width of the opened magnetic levitation left sliding door 2 and magnetic levitation right sliding door 5. This setup can intelligently guide passengers. In addition, compared to existing sliding doors, this solution places the controller 3 in the control box 4 and places the magnetic levitation left sliding door 2 and magnetic levitation right sliding door 5 on both sides of the control box 4. Therefore, when moving, the magnetic levitation left sliding door 2, the control box 4, and the magnetic levitation right sliding door 5 move simultaneously, thus achieving a larger range of changes in the effective passage width and enabling flexible application in diverse operating scenarios.

[0041] This invention also includes a radar detector 11, which is installed on the magnetic levitation left sliding door 2 and / or the magnetic levitation right sliding door 5 and connected to the controller 3 inside the control box 4.

The train model recognition device is a high-definition camera 12, which is installed on the control box 4 and connected to the controller 3 inside the magnetic levitation left sliding door 2 and / or the magnetic levitation right sliding door 5. The high-definition camera 12 can automatically identify the train model and the train's arrival status, thereby facilitating the controller 3 to control the position and width of the magnetic levitation left sliding door 2 and the magnetic levitation right sliding door 5 that need to be opened.

[0042] like Figure 6-8 As shown, the control box 4 includes a control box body 13, a support frame 14, a connecting plate 15, a tank chain cable groove 16, a status indicator light 17, and a support plate 19 with positioning holes 18; the magnetic levitation motor actuator 9, the electromagnet 26, and the positioning sensor 10 are all mounted on the support frame 14; the connecting plate 15 is mounted on the top of the support frame 14, and the support plate 19 is mounted on the connecting plate 15; the control box body 13 is mounted on the support plate 19 with positioning holes 18 via positioning components (such as screws); the status indicator light 17 is mounted on the control box body 13; the controller 3 is mounted inside the control box body 13, and the wires on the controller 3 are connected to the tank chain cable groove 16 respectively. The train model identifier, the magnetic levitation motor mover 9, the status indicator light 17, the electromagnet 26, and the positioning sensor 10 are connected. Through the setting of the magnetic levitation motor mover 9 and the magnetic levitation motor stator 7, when the magnetic levitation motor mover 9 is energized, the magnetic levitation motor mover 9 and the magnetic levitation motor stator 7 repel each other, and the support frame 14 can move better on the track platform 6. The positioning sensor 10 can sense the position of the support frame 14. In addition, the support plate 19 can be used to support the control box 13. When the support frame 14 moves into position, the status indicator light 17 can give a corresponding reminder of the position of the support frame 14.

[0043] In this invention, the support frame 14 has sliders 20 on both sides, and the track platform 6 has a slide rail 21. The support frame 14 is fitted onto the slide rail 21 of the track platform 6 via the sliders 20. The sliders 20 and the slide rail 21 facilitate the limited movement of the support frame 14. Extended edges 22 are provided at the bottom of the magnetic levitation left sliding door 2 and the magnetic levitation right sliding door 5. The bottoms of the magnetic levitation left sliding door 2 and the magnetic levitation right sliding door 5 are fixed to the positioning holes via the extended edges 22. On the support plate 19 of 18, by setting the extended side 22, the bottom of the magnetic levitation left sliding door 2 and the magnetic levitation right sliding door 5 can also be stably fixed on the support plate 19, thereby strengthening the fixation of the magnetic levitation left sliding door 2 and the magnetic levitation right sliding door 5. In this utility model, a reinforcing rib 23 is provided on the support frame 14. The reinforcing rib 23 is attached to both sides of the magnetic levitation motor mover 9. By setting the reinforcing rib 23, the magnetic levitation motor mover 9 can be strengthened and fixed.

[0044] In addition, in this utility model, the bottom of the magnetic levitation left sliding door 2 and the magnetic levitation right sliding door 5 is provided with an apron anti-pinch brush 24. By setting the apron anti-pinch brush 24, the situation of the magnetic levitation left sliding door 2 and the magnetic levitation right sliding door 5 being pinched during movement can be avoided. The magnetic levitation left sliding door 2 and the magnetic levitation right sliding door 5 are made of glass material. In practical applications, the magnetic levitation left sliding door 2 and the magnetic levitation right sliding door 5 can also be made of other materials, which are all alternative solutions that are easy for those skilled in the art to think of. In this utility model, a wire groove 25 is provided on the track platform 6. The setting of the wire groove 25 can facilitate wiring and is simple and practical. In practical applications, a connecting hole 27 can also be set on the support frame 14 to facilitate wiring.
