Description

Technical Field

[0001] This utility model relates to the field of shielded doors, and more specifically, to a magnetic levitation door drive installation structure. Background Technology

[0002] Magnetic levitation technology, with its non-contact, low-friction, and high-precision characteristics, has been increasingly widely used in modern rail transit platform screen door systems. The basic principle of this technology is to use electromagnetic force to levitate and drive moving parts. Specifically, in the field of screen doors, a typical magnetic levitation drive system includes: several electromagnets set below the moving part (such as the door body), and a magnetic levitation linear motor composed of a stator and a mover. By energizing the electromagnets, a repulsive or attractive force is generated with the magnetically conductive track below, causing the moving part to overcome gravity and levitate. Subsequently, by controlling the current supplied to the mover of the linear motor, the principle of "like poles repel and unlike poles attract" between magnetic poles is used to generate propulsion force, thereby precisely controlling the moving part to translate along a predetermined path.

[0003] In existing technologies, in order to support and drive heavy platform screen door systems, a high-density, high-power magnetic levitation component layout is usually adopted. Specifically, a row of continuously distributed electromagnets is set along the entire length of the moving parts or at key load-bearing locations to provide sufficient and uniform levitation force. At the same time, a row of stators and movers of magnetic levitation linear motors is also set to ensure strong driving thrust and smooth control performance. This "full-row" design is a necessary technical means to ensure the operational stability and safety of heavy and large platform screen doors.

[0004] However, when this mature solution designed for heavy equipment is directly applied to lighter platform screen doors (such as small platform screen doors for low-passenger-flow lines or specific areas), its technical and economic irrationality becomes apparent. For lightweight doors, the required levitation force and driving force are much smaller than those for heavy doors. In this case, while using the original high-density electromagnet and motor arrangement can meet or even exceed expectations in terms of performance, it undoubtedly results in functional redundancy and resource waste. The use of a large number of electromagnets, stators, and movers, as well as the supporting large-capacity power supply and control modules, directly leads to a sharp increase in system manufacturing costs. This makes magnetic levitation, an advanced technology, uncompetitive in cost-sensitive low-to-medium load application scenarios, limiting the further popularization of its technological advantages.

[0005] Therefore, it is necessary to propose a magnetic levitation door drive installation structure to solve the above problems. Utility Model Content

[0006] To overcome at least one of the defects (deficiencies) of the prior art described above, this utility model provides a magnetic levitation door drive installation structure.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a magnetic levitation door drive installation structure, including a controller cabinet, a drive controller, a magnetic levitation shielded door, a track platform, and a support frame for supporting the controller cabinet;

[0008] The track platform is provided with a slide rail, and the support frame is provided with a slider. The support frame is movably fitted onto the slide rail of the track platform via the slider.

[0009] The track platform is equipped with a magnetic levitation motor stator and a magnetically conductive track. The support frame is equipped with a magnetic levitation motor mover and an electromagnet for levitizing the support frame relative to the magnetically conductive track when energized. The magnetic levitation motor mover and the electromagnet are respectively arranged side by side on both sides of the middle part of the support frame. The electromagnet and the magnetic levitation motor mover are respectively connected to the drive controller.

[0010] Both the drive controller and the magnetic levitation shielding door are mounted on the controller cabinet. When the electromagnet is energized, it can levitate the entire support frame from the middle. When the magnetic levitation motor is energized, its interaction with the magnetic levitation motor stator on the track platform causes the support frame to move relative to the track platform. The slider and slide rail provide support and guidance. For lighter magnetic levitation doors, by placing the magnetic levitation motor mover and electromagnet on both sides of the middle of the support frame, the lighter magnetic levitation door can be levitated and driven, thus effectively simplifying the installation structure of the magnetic levitation door drive.

[0011] Furthermore, the support frame is provided with reinforcing ribs, and the two ends of the magnetic levitation motor mover abut against the outside of the reinforcing ribs. The reinforcing ribs can strengthen and fix the magnetic levitation motor mover.

[0012] Furthermore, the support frame is provided with a connecting plate for fixing the controller cabinet. The connecting plate can strengthen and fix the controller cabinet.

[0013] Furthermore, the support frame, connecting plate, and reinforcing ribs are an integral structure, which effectively simplifies the structure of the support frame.

[0014] Furthermore, the connecting plate is provided with mounting positioning holes for installing the controller cabinet. The mounting positioning holes make it easy and convenient to install the controller cabinet onto the connecting plate.

[0015] Furthermore, the connecting plate is provided with through holes for the wires of the controller cabinet or the drive controller to pass through. The through holes facilitate the connection between adjacent controller cabinets and the fixation of the drive controller, which is simple and practical.

[0016] Furthermore, the support frame is provided with a connecting hole, and the electromagnet is located directly below the connecting hole. The connecting hole facilitates wiring.

[0017] Furthermore, it also includes an electromagnet support base, on which the electromagnet is mounted on a support frame directly below the connecting hole. The electromagnet support base facilitates the installation and fixation of the electromagnet.

[0018] Furthermore, the support frame is equipped with a positioning sensor, and the track platform is equipped with an arrival sensor that matches the positioning sensor. By setting the arrival sensor, it can be used to sense each other with the positioning sensor, thereby judging the movement of the support frame.

[0019] Furthermore, there is at least one position sensor. In practical applications, the number of position sensors can be set as needed, which are all solutions that are easy for those skilled in the art to conceive of.

[0020] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0021] The magnetic levitation gate drive installation structure disclosed in this utility model allows the support frame to be levitated when the electromagnet is energized, with the electromagnet suspending the entire support frame from the middle. When the magnetic levitation motor mover is energized, its interaction with the magnetic levitation motor stator on the track platform causes the support frame to move relative to the track platform. The slider and slide rail provide support and guidance. For lighter magnetic levitation gates, by placing the magnetic levitation motor mover and electromagnet on both sides of the middle of the support frame, the lighter magnetic levitation gate can be levitated and driven, effectively simplifying the installation structure of the magnetic levitation gate drive.

[0036] Example

[0037] In this embodiment, when the electromagnet is energized, it can levitate the entire support frame from the middle of the support frame. When the magnetic levitation motor is energized, the magnetic levitation motor mover interacts with the magnetic levitation motor stator on the track platform, causing the support frame to move relative to the track platform.
