Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and in particular to a prefabricated F-type rail. Background Technology

[0002] Medium and low speed maglev guide rails use special steel with an "F" shaped cross section for medium and low speed maglev tracks. They interact with maglev vehicles to achieve the functions of vehicle levitation, traction, guidance and braking. They are generally produced by rolling.

[0003] CN201288279Y discloses a hot-rolled F-shaped special steel for medium- and low-speed maglev train tracks, which solves the problems of high production cost and low efficiency of steel plate welding, and is suitable for mass production and engineering applications. CN118720339A discloses a medium- and low-speed maglev guide rail and its welding method. When the required quantity is small, the method of welding steel plates and then machining is adopted to solve the problem of excessive rolling cost.

[0004] F-shaped steel has an irregular cross-section, making it difficult to roll and resulting in a long delivery cycle. Using steel plate welding methods has problems such as large welding deformation and large machining volume.

[0005] Therefore, it is necessary to provide a new assembled F-type rail to solve the above-mentioned technical problems. Utility Model Content

One end of the installation body is disposed on the rail body, and the other end is connected to the U-shaped structure through the connector. The assembled F-shaped rail can be magnetically attracted to an electromagnet to generate levitation force.

[0008] Optionally, the mounting body includes a wing plate and a web plate connected together, the connection between the wing plate and the web plate forming a stepped surface, the wing plate being connected to the track body; the web plate being connected to the U-shaped structure via the connector.

[0009] Optionally, the mounting body is a one-piece molded component.

[0010] Optionally, the wing plate is provided with a welding area; the web plate overlaps the welding area and is welded to the wing plate.

[0011] Optionally, the U-shaped structure includes a plurality of stacked U-shaped bending plates, the size of the plurality of U-shaped bending plates decreasing sequentially in the direction away from the web plate, and the inner wall of the previous U-shaped bending plate being in contact with the outer wall of the next U-shaped bending plate.

[0012] Optionally, the U-shaped bending plate is a one-piece molded part.

[0013] Optionally, the connector includes a bolt and a fastening nut, wherein the bolt passes sequentially through the web and each of the U-shaped bends and is threadedly connected to the fastening nut.

[0020] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0021] This utility model proposes an assembled F-type rail, aiming to solve the problem of the high production difficulty of existing assembled F-type rails.

[0022] Example 1

[0023] like Figure 1As shown, the assembled F-shaped rail includes a mounting body 1, a U-shaped structure 2, and a connector 3. One end of the mounting body 1 is mounted on the rail body, and the other end is connected to the U-shaped structure 2 via the connector 3. The assembled F-shaped rail can be magnetically attracted to an electromagnet to generate levitation force. The mounting body 1 and the U-shaped structure 2 are assembled using the connector 3 to obtain the F-shaped rail. This method is simple to operate, convenient to assemble, requires less welding and machining, which helps ensure processing quality and efficiency, solves the problem of high costs associated with rolling or steel plate welding machining, and effectively reduces the production difficulty of the F-shaped rail. In this embodiment, the U-shaped structure 2 forms inner and outer legs that correspond to the two magnetic poles of the electromagnet, respectively.

[0024] The mounting body 1 includes a wing plate 1.1 and a web plate 1.2 connected to each other. The connection between the wing plate 1.1 and the web plate 1.2 forms a stepped surface 1.3. The wing plate 1.1 is connected to the track body. The web plate 1.2 is connected to the U-shaped structure 2 through a connector 3.

[0025] Specifically, the mounting body 1 is a one-piece molded component. The one-piece molding mounting body 1 can be obtained by bending the steel plate into a Z-shaped structure with a stepped surface of 1.3, which can meet the structural requirements and reduce the processing difficulty.

[0026] Furthermore, the U-shaped structure 2 includes multiple stacked U-shaped bent plates 2.1. The dimensions of the multiple U-shaped bent plates 2.1 decrease sequentially in the direction away from the web 1.2, and the inner wall of the upper U-shaped bent plate 2.1 fits against the outer wall of the lower U-shaped bent plate 2.1. The U-shaped bent plate 2.1 includes a mounting part and a bending part connected to both ends of the mounting part. The mounting part of each U-shaped bent plate 2.1 is connected to the web 1.2 through a connector 3. The bending parts at both ends of each U-shaped bent plate 2.1 are stacked to form the inner leg and outer leg of the U-shaped structure 2. In actual operation, the operator can increase or decrease the number of U-shaped bent plates 2.1 according to actual needs to change the size of the inner leg and outer leg, thereby meeting different application requirements.

[0027] Furthermore, the U-shaped bending plate 2.1 is a one-piece molded component. The U-shaped bending plate 2.1 is made by bending a steel plate into a U-shaped structure 2, which eliminates the need for rolling or welding processes, reducing the amount of welding work in the production process of F-shaped rails and lowering the processing difficulty.

[0028] In addition, the connector 3 includes bolts 3.1 and fastening nuts 3.2. Bolts 3.1 pass through the web 1.2 and each U-shaped bending plate 2.1 in sequence and are threadedly connected to the fastening nuts 3.2. Using bolts 3.1 and fastening nuts 3.2 to connect the web 1.2 and the U-shaped structure 2 can ensure the connection strength between the mounting body 1 and the U-shaped structure 2, and also facilitates flexible changes in the number of U-shaped bending plates 2.1 to adjust the size of the inner and outer legs to meet different needs.

[0029] Example 2

[0030] The difference from Embodiment 1 is that: the wing plate 1.1 is provided with a welding area 1.1.1; the web plate 1.2 overlaps the welding area 1.1.1 and is welded to the wing plate 1.1. Welding after overlapping the wing plate 1.1 and the web plate 1.2 is convenient and the welding difficulty is low.

[0031] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
